Executive Summary

This report describes the risks associated with

coal combustion waste (CCW) disposal and how

Iowa and the federal government are handling

the challenge. As the Clean Air Act

progressively restricts the air contaminants that

issue from smokestacks, CCW becomes

increasingly contaminated with pollutants

removed from the air. The waste stream is

disposed of in a variety of ways, including

sanitary landfills, industrial re-use, road

building, fill for construction projects, and

filling of abandoned mines and quarries.

Without proper precautions, land-disposed

CCW can leach toxic heavy metals into

groundwater and surface water.

In comparison to coal, CCW is relatively

enriched in elements such as arsenic, selenium,

chlorine, copper, zinc, and mercury. Heavy

metals are far more concentrated in bottom ash

and fly ash than in the source coal prior to

combustion. Emission controls exacerbate these

differences by removing heavy metals from air

emissions and concentrating them in CCW.

Disposing of the various forms of coal

combustion waste can represent a significant

expense to operators of coal-fired power plants.

The cheapest means of disposal is therefore

attractive to coal plant operators nationwide.

Coal ash currently crosses state boundaries in

search of the cheapest disposal sites. “In

addition to mining and air quality problems

caused by coal, we now have a land and water

problem caused by coal combustion waste,”

says Carrie La Seur, one of the report’s authors

and founder of Plains Justice.

Findings

Iowa’s Coal Combustion Waste Regulations

Pose a Significant Risk to Human Health and

the Environment

Iowa is currently importing CCW from as far

away as Indiana. The likely explanation for the

distant imports is Iowa’s loose regulation of this

waste stream, which keeps costs low but

increases the risk of undetected groundwater

contamination for Iowa residents. Iowa has

nearly two dozen sites at which CCW has been

used as “fill” without any liner, groundwater

monitoring, or financial assurances in case of

contamination. At least four sites use perhaps

the riskiest form of storage: filling unlined

quarries with vast amounts of CCW.

A significant portion of Iowa’s CCW is

being dumped in unlined quarries near

residential areas or rural water supplies, without

groundwater monitoring or financial assurances.

The primary risk from such poor disposal

practices is contamination of ground water not

only with arsenic but also with other heavy

metals such as cadmium, chromium, lead,

thallium, boron, selenium, nickel, molybdenum,

antimony and vanadium.

These metals are called trace elements

because they exist in trace amounts in the

environment, but it is important to understand

that they are toxic in trace amounts. Other more

soluble pollutants present in even greater

quantities in ash, such as sulfate, iron,

Page 6: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

vi

manganese, calcium, magnesium, sodium and

chloride, can often be bellwethers of

contamination yet to come from trace heavy

metals that will tend to leach more slowly from

the ash, dissolving into groundwater in

dangerous concentrations as factors limiting

their solubility change over time.

The Public Lacks Information About the Risk

The public has received little information about

the true nature of this risk. Developers of a

proposed 750 megawatt coal plant at Waterloo,

Iowa, tout CCW fill as an “environmental

benefit” of their plant. Indeed, the permitting

program run by the Iowa Department of Natural

Resources (IDNR) is referred to as “beneficial

use” permitting for CCW that may go into

everything from road construction to gypsum

wallboard to filling up old quarries. However,

the benefits of “beneficial use” fill sites are far

from clear, and federal regulation of this waste

stream has a long, troubled history.

The Public Lacks Access to Permitting and

Monitoring Data

IDNR does not have basic permitting and

enforcement data for this waste stream on its

website. Paper files available at the central

records repository in Des Moines lack complete

data even for sites where monitoring has taken

place. The lack of access to such basic

information hampers citizen involvement in the

permitting and enforcement process. Public

access is critical to each Iowa resident’s ability

to assess risks posed by existing and proposed

land uses. Access to thorough public

environmental records is essential to good

government at the local, county and state level.

Direct public access to such records also

improves the incentives for regulatory

compliance for regulated entities.

State and Federal Regulatory Reform Is Long

Overdue

State CCW regulation has become a patchwork

because of a remarkable 27-year failure by the

U.S. Environmental Protection Agency (EPA)

to issue comprehensive regulations for the

proper management of CCW. The National

Academies of Science have recommended

national regulations that would set minimum

safeguards at CCW placed in surface mines.

However, EPA has let its obligation to regulate

CCW in these and other sites languish. What

remains is a largely voluntary system of

inconsistent state regulations and administrative

guidelines that condones existing CCW

management practices regardless of the hazards.

One hazard of poorly regulated CCW

disposal is contamination of groundwater, which

leads to increased cancer risk. EPA studies

indicate that disposing of CCW in unlined

surface impoundments creates a risk of cancer

due to arsenic exposure through contaminated

groundwater of up to one person in 100. This

level of risk is 10,000 times higher than EPA’s

regulatory goals for reducing cancer. The

harmful impact of excessive levels of heavy

metals such as mercury and lead on human

physiology is well documented. Risks for

children are particularly serious and include a

wide range of neurological and developmental

disorders.

Iowa’s regulatory regime for CCW

landfill sites and for “beneficial use” of CCW

fill poses significant risks of undetected

environmental contamination, significant

liability risks to fill site operators, and

significant health risks to Iowans. In light of the

documented risks to human health and the

environment, the authors of this report strongly

recommend immediate cessation of “beneficial

use” fill permits and closure of fill sites.

Closure should proceed according to

recommended closure and post-closure practices

for coal ash sanitary landfills.

National regulation, both of CCW

landfill sites and “beneficial use”

determinations, is desirable because of the

fluidity of CCW across state borders. A state by

state project of regulatory reform has the risk of

commencing a race to the bottom, in which

CCW finds its way to the most loosely regulated

state, which in the Midwest may be Iowa. Until

national reform takes place, Iowa must improve

its CCW disposal regime to avoid becoming, or

remaining, a regional net recipient of this

hazardous waste stream.

Immediate Action Is Necessary to Protect

Iowa Ground and Surface Waters

In addition to the detailed recommendations for

Iowa regulatory reform included at the end of

this report, the authors recommend the

following four steps as urgently needed for the

protection of public health and the environment:

1. Halting further permitting, renewal or

expansion of fill sites;

2. Closing existing fill sites on the most

expeditious, yet practicable schedule

(within two years);

3. Imposing immediate and long-term

monitoring at existing fill sites; and

4. Mandating cleanup of contamination

detected at existing sites.

Without immediate preventive action, Iowans

are at significant risk for drinking water

contamination and taxpayer financial liability

for cleanups. Swift action by Iowa regulators

could substantially reduce these risks.

Federal Regulatory Reform Is Necessary But

Not Sufficient

This report includes, as an appendix, a recent

proposal for federal regulatory reform.

Although federal reform is badly needed, it is

unlikely to come quickly enough to protect

Iowans’ health and natural environment from

the existing risk. Waiting for federal reform on

coal combustion waste disposal, originally

ordered by Congress some 27 years ago, is not a

viable strategy.

Introduction

The United States’ current energy structure is dominated

by fossil fuels, and Iowa is no exception. Coal

combustion produces up to 85% of Iowa’s electricity.1

Because the power industry can’t prevent all the

environmental and public health harms caused by coal

simply by installing the pollution control technologies

required under the Clean Air Act, the price of coal

currently does not reflect its true cost to society. The

extent of the U.S. coal supply is currently a subject of

debate,2 but the massive American reliance on coal for

electricity and proposals for many new coal plants raise

the question of what health and environmental costs will

be imposed on the population during the life cycle of new

plants.

These costs are not hard to envision, given a

typical 500 megawatt coal plant’s annual output: 10,000

tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon dioxide, 220 tons of

hydrocarbons, 720 tons of carbon monoxide, 125,000 tons of ash and 193,000 tons of sludge from the

smokestack scrubber, 225 pounds of arsenic, 114 pounds of lead, 4 pounds of cadmium, trace elements

of uranium, plus many other toxic heavy metals.3 These pollutants cause known damage to human

health, with a spectrum that runs from increased asthma rates to neurological damage caused by mercury

exposure and respiratory mortality in vulnerable populations such as children and the elderly. However,

airborne pollutants are not the only environmental contamination risk from coal combustion.

As the Clean Air Act progressively restricts the air contaminants that issue from smokestacks,

coal combustion by-products become increasingly contaminated with pollutants removed from the air.

“You’re replacing an air problem with a land problem - a disposal problem,” says Bruce Dockter, a

research engineer with the Energy and Environmental Research Center at the University of North

Dakota.4 Although originally directed by Congress in 1980 to develop a safe disposal regime for CCW,

the U.S. Environmental Protection Agency (“EPA”) still has not done so, allowing instead a patchwork

of insufficiently protective state regulations. Regulation of CCW disposal sites in Iowa is entirely under

the authority of the Iowa Department of Natural Resources (IDNR).

Coal of all varieties consists of greatly compressed layers of fossilized plants, including all the

metals taken up by those plants millions of years ago. Analyses of coal ash have long established that

coal combustion results in an even greater concentration of these metals in the solid waste that results

when coal is combusted and its volume reduced by 80 percent to that of ash. According to a 1976 study,

This report describes Iowa’s

regulation of Coal Combustion

Waste (CCW), identifies potential

risks, and recommends state and

federal regulatory reform needed

for the protection of public health

and ecosystems. As new sources

of CCW in Iowa and nearby states

are proposed, with Iowa disposal

sites targeted for hundreds of

thousands of tons of additional

CCW, this issue becomes more

and more urgent.

in comparison to coal, fly ash is relatively enriched in elements such as chlorine, copper, zinc, arsenic,

selenium, and mercury.5 A more recent study indicates that fly ash is also enriched in boron, strontium,

molybdenum, sulfur, and calcium.6 Trace elements in the ash are concentrated in the smaller ash

particle sizes.

A pilot study by the Electric Power Research Institute (1983)7 revealed large quantitative

differences in elemental concentrations in coal, bottom ash, and fly ash from a southwest U.S. power

plant burning southwestern subbituminous coal:

Aluminum Arsenic Barium Chromium Iron Magnesium Lead Silicon

(ppm)8 (ppb)9 (ppm) (ppm) (ppm) (ppm) (ppb) (ppm)

Coal 29100 7100 71.8 6.1 5130 1130 11000 50200

Bottom Ash 142000 24100 2830 29 28100 4640 23000 260000

Fly Ash 144000 32750 3110 31 24800 5260 51500 258000

The EPRI study demonstrates that heavy metals are far more concentrated in bottom ash and fly ash

than in the source coal prior to combustion.

Emission controls exacerbate these differences by removing heavy metals from air emissions and

concentrating them in CCW. Elevated heavy metal concentrations in CCW were revealed in studies of

the mobilization, or movement in the environment, of trace metals from coal-burning power plants in

Europe.10

This quantitative evaluation looked at stack emissions and the quantities of metals retained in

ash by electrostatic filters (an air pollution control device).

Researchers concluded that modern electrostatic filters can filter out 99.8% of particulate matter

(soot). Consequently, the largest environmental risk associated with most of the metals from coal-

burning power plants is from potential releases from solid waste. Analyses of trace metals present in

coal revealed that of the total mobilization of these metals in the combustion process, the great majority

of the metals were retained in the solid waste and only a very small percent were present in the

atmospheric stack emissions.

For example, for the trace metals charted below, a very high percentage of the total mobilization

of each metal was retained and concentrated in the coal ash. 11

Trace metal Arsenic Cadmium Chromium Lead Antimony Selenium % retained and concentrated in coal ash

97% 97.2% 99% 97.5% 97.7% 91.5%

Disposing of the various forms of coal combustion waste can represent a significant expense to

operators of coal-fired power plants. The cheapest means of disposal is therefore attractive to coal plant

operators nationwide. Coal ash currently crosses state boundaries in search of the cheapest disposal

sites.

Iowa has more than a dozen CCW landfills and over 20 CCW “beneficial use” sites. Some are

currently importing CCW from as far away as Indiana.12

The likely explanation for the distant imports

is Iowa’s loose regulation of this waste stream, which keeps costs low but increases the risk of

undetected groundwater contamination for Iowa residents. In Iowa today, CCW continues to be used as

fill without any liner, groundwater monitoring, or financial assurance in case of contamination. At least

four sites use perhaps the riskiest form of storage: filling unlined, unmonitored quarries with vast

3

amounts of CCW.13

In spite of the acknowledged risk, EPA admits that it does not know how many such unlined

facilities exist around the U.S.14

Although the National Academies of Science have recommended

national regulations that would set minimum safeguards at CCW placed in surface coal mines,15

EPA

has let its commitment to develop regulations for CCW in other sites languish. What remains is a

largely voluntary system of inconsistent state regulations and administrative guidelines that condones

existing CCW management practices regardless of the hazards posed.16

This is no de minimis problem. CCW is a vast waste stream. The U.S. Department of Energy’s

Energy Information Administration estimates that U.S. coal burners produced 129 million tons of coal

ash in 2004, a quantity comparable to the 245 million tons of municipal solid waste produced in the U.S.

in 2005.17

The annual generation of CCW in the U.S. alone would fill the box cars of a train extending

from Washington, D.C., to Melbourne, Australia, yet this massive toxic waste stream is usually less

strictly regulated than municipal waste disposal.

This report describes Iowa’s regulation of CCW, identifies potential risks, and recommends state

and federal regulatory reform needed for the protection of public health and ecosystems. As new

sources of CCW in Iowa and nearby states are proposed, with Iowa disposal sites targeted for hundreds

of thousands of tons of additional CCW, this issue becomes more and more urgent. Although specific

sites are discussed as examples, the goal of this report is to prescribe state-level solutions to a national

regulatory problem, not to perform a comprehensive analysis of the compliance status or risks associated

with any single Iowa CCW disposal site.

Contamination Risks

Associated With CCW

Disposal

A significant portion of Iowa’s CCW is being dumped in unlined quarries adjacent to residential areas

or rural water supplies, without groundwater monitoring or financial guarantees in case of

contamination. The primary risk from such poor disposal practices is contamination of ground water not

only with arsenic but also with other heavy metals such as cadmium, chromium, lead, thallium, boron,

selenium, nickel, molybdenum, antimony and vanadium. These metals are called trace elements

because they exist in trace amounts in the environment, but it is important to understand that they are

toxic in trace amounts. Other more soluble pollutants present in even greater quantities in ash, such as

sulfate, iron, manganese, calcium, magnesium, sodium and chloride, can often be bellwethers of

contamination yet to come from trace heavy metals that will tend to leach more slowly from the ash,

dissolving into groundwater in dangerous concentrations as factors limiting their solubility change over

time.

Quarries are unlined sites, usually in sand and gravel aquifers that are highly conductive to

water, precisely the places for which EPA has documented the greatest potential for damages to occur

from CCW. While the federal government has been slow to acknowledge the scope of the threats posed

by CCW, in a recent admission, EPA states:

EPA has gathered or received information on 135 possible damage cases. . . .

After reviewing these 135 damage cases, EPA identified 24 proven damage cases.

The overwhelming majority of the damage cases reflect management in unlined

units—that is, all but one of the 24 proven damage cases involved unlined CCW

management units, including six cases involving disposal of CCW in unlined sand

and gravel pits. . . . . Four of the proven damages to ground water were from

unlined landfills, 5 were from unlined surface impoundments, 1 was due to liner

failure at a surface impoundment, and the remaining 6 were from unlined sand

and gravel pits.18

Thus one fourth of the sites acknowledged by EPA as proven examples of CCW contaminating

off site groundwater supplies involve unlined sand and gravel pits. At least one additional proven

damage case involves a limestone quarry. EPA acknowledges that five other sand and gravel quarries

where CCW has been placed are “potential” damage sites for which more information is needed. In

assessing the dangers posed by CCW landfills and surface impoundments, EPA states:

The risk assessment also suggests that one of the most sensitive parameters in the

risk assessment is infiltration rate. Infiltration rate is greatly influenced by

whether and how a WMU (Waste Management Unit) is lined.19

There are few environments with infiltration rates of surface waters to groundwaters exceeding

infiltration rates occurring at sand and gravel quarries. The hydraulic conductivity of sand and gravel

aquifers is very high (with water moving through them at 10-2

to 10-3

cm/sec or faster). The lack of a

liner at such a site assures ready and uninterrupted infiltration of coal ash leachate into groundwater.

The following are several examples of quarries where CCW has contaminated human drinking

water:

• Highway 59 Ash Landfill, Waukesha, Wisconsin: Operators placed just 8,000 tons (a

relatively small amount) of CCW below the water table in a sand and gravel pit, a glacial

unconsolidated aquifer adjacent to a dolomite aquifer. Resulting contamination of 13 offsite

drinking water wells with boron, molybdenum and sulfates exceeding state health standards cost

an estimated $6.6 million to abate.20

• Port Washington Fly Ash Landfill, Wisconsin: Two drinking water wells were contaminated

with selenium and boron exceeding state health standards from coal ash dumped in a sand and

gravel quarry. After contaminating a first well screened 50 feet deep into the Niagara Dolomite

aquifer, 250 feet away from the site, the plume from the ash contaminated a second well dug 160

feet into this hard rock aquifer.21

Dolomite, a limestone carbonate rock with as much magnesium as calcium, will fracture

as much if not more than limestone, although it is prone to less dissolution and formation of

karst. Midwestern sand and gravel quarries along rivers and from glacier deposits are often over

or near carbonate rock, i.e. limestone and dolomite. The fractures and dissolution channels in

this rock provide pathways that enhance contaminant migration away from coal ash dumped into

Midwestern sand and gravel quarries.

• Chisman Creek Disposal Site, Virginia: Wells for 55 homes were contaminated by fly ash

from the combustion of coal and petroleum coke dumped into abandoned sand and gravel pits on

27 acres. Disposal at the site ended in 1974, but water in nearby residential wells became

contaminated in 1980 with sulfate, selenium and vanadium, turning green and exceeding federal

Drinking Water Standards (DWS) for selenium and sulfate (there is no DWS for vanadium). The

shallow groundwater, on-site ponds, and sediments of Chisman Creek and its tributaries became

contaminated with arsenic, beryllium, chromium, copper, molybdenum, nickel, vanadium and

selenium.

A four year Superfund clean up of the site was necessary to extend public water to the 55

homes, cap disposal pits with soil and compacted clay and vegetation, collect groundwater and

leachate for treatment, lower the water table between the disposal pits, and initiate post closure

monitoring of the pits. Additionally, 600 feet of a tributary to Chisman Creek had to be

relocated to minimize contact with fly ash areas, surface runoff from the site had to be diverted,

and longterm monitoring established for ponds, the tributary and an adjacent estuary.22

• Gambril’s Ash Disposal Site, Maryland: Four million tons of coal ash disposed in two sand

and gravel pits since 1995 has contaminated water in at least 23 nearby residential wells with

cadmium, thallium and lead exceeding DWS necessitating the emergency provision of bottled

water to home owners. In all, detectable levels of metals have been found in least 50 wells. The

generator of the CCW and the operator of the ash dump have been fined $1 million by the

Maryland Department of the Environment and ordered to clean up the site. The County Council

of Anne Arundel County where the site is located has passed a one year ban on any new ash sites

within the County.23

The site is not yet recognized by EPA as a damage case.

Human Health

Hazards

One externality of poorly regulated CCW disposal is contamination of groundwater, which

leads to increased cancer risk. For example, the cancer risk of adults and children who drink

from groundwater that is contaminated with arsenic from CCW can be as high as 1 in 100, which

is 10,000 times higher than EPA’s regulatory goals for reducing cancer.24

EPA studies indicate a

risk of cancer due to arsenic exposure through contaminated groundwater of up to 1 in 100 for

CCW disposal in unlined surface impoundments.25

The impact of excessive levels of heavy

metals on human physiology is well documented. Following are the effects of some of the

better-known metals.

Arsenic

Arsenic is acutely toxic: drinking water with an arsenic level of 60 parts per million is lethal, and

far lower levels of exposure are directly linked to cancer.26

According to Harvard University’s

Arsenic Project:

After several years of low level arsenic exposure, various skin lesions appear.

These are manifested by hyperpigmentation (dark spots), hypopigmentation

(white spots) and keratoses of the hands and feet. After a dozen or so years skin

cancers are expected. Twenty or thirty years after exposure to 500 [parts per

billion] of arsenic, internal cancers (lung, kidney, liver and bladder) appear among

10% of all exposed.27

Other toxic metals have similarly severe impacts. Health risks associated with chronic increased

consumption of selenium include discoloration of the skin, pathological deformation and loss of

Page 15: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

8

nails, loss of hair, excessive tooth decay and discoloration, lack of mental alertness, and

listlessness.

Cadmium and Molybdenum

Excessive intake of cadmium has been linked to kidney damage and increased risk of prostatic

and respiratory cancers.28

Adverse health impacts reported from molybdenum exposure have

included liver dysfunction with hyperbilirubinemia in workmen chronically exposed in the

Soviet Union and gout in factory workers in Armenia. Notable symptoms include joint pains in

the knees, hands, feet, articular deformities, erythema, and edema of the joint areas.29

Lead

Lead poisoning, a more familiar heavy metal risk due to the prevalence of lead in older paint, has

a host of harmful health impacts. Children under age six are especially vulnerable because their

brains and central nervous systems are in development. Even very low levels of lead exposure in

small children can cause reduced IQ, learning disabilities, attention deficit disorders, behavioral

problems, stunted growth, impaired hearing, and kidney damage. High levels of exposure can

cause mental retardation, coma, and death. Iowa’s lead poisoning level is nearly three times the

national average.30

In a community, the presence of lead-poisoned children can be associated with an

increase in the number of children with developmental deficits and learning

disorders. This places an unnecessary and expensive burden on the educational

system. The presence of lead-poisoned children also requires substantial

community public health resources for medical and environmental case

management services.31

Lead exposure in adults can increase blood pressure, cause fertility problems, nerve disorders,

muscle and joint pain, irritability, and memory or concentration problems. Unborn children are

at risk: lead crosses the placenta and can contaminate a fetus through the mother’s blood.

Pregnancy can also cause lead stored in the mother’s bones to be released and enter the blood

stream, causing the baby to be born with an elevated blood lead level.

Under current regulations for disposal of heavy metal-contaminated CCW in Iowa

“beneficial use” fill sites, there is no way to determine if or how much leachate comes in

contact with the groundwater. The hydrogeology of quarry sites in particular creates

significant opportunity for CCW leachate to reach the groundwater or migrate to surface

water. Iowa’s current regulatory regime therefore represents a significant public health

risk.

Crawford Quarry

in Cedar Rapids,

a CCW “beneficial use”

fill site

in a residential

neighborhood, less than a mile

from three schools.

Epidemiologists measure lead levels

in micrograms of lead per deciliter of

blood to indicate the severity of

exposure. The U.S. Centers for

Disease Control and Prevention (CDC) have a “level of concern” for children of 10 micrograms

per deciliter. This level of exposure is generally accepted as the point of onset of adverse health

effects. However, the New England Journal of Medicine recently published a study indicating

that very harmful effects may well occur at levels of exposure as low as 5 micrograms of lead per

deciliter of blood.32

The best science now tells us that there may be no safe level of exposure to

lead.

History of U.S. CCW

Regulation

The U.S. Congress has grappled with the issue of safe disposal of CCW since 1980, when it

temporarily exempted from regulation as hazardous under the Resource Conservation and

Recovery Act (“RCRA”) Subtitle C certain large-volume wastes generated primarily from the

combustion of coal or other fossil fuels.33

These large-volume wastes are fly ash, bottom ash,

slag waste, and flue gas emission control (“FGD”) wastes.34

Congress directed EPA to perform

a study and publish the results in a Report to Congress (“RTC”) concerning potential adverse

effects on human health and the environment of the disposal of CCW. In addition, Congress

ordered EPA to determine whether the temporarily exempt status of CCW as hazardous waste

was warranted.35

Because EPA did not publish its report within the required timeline, a citizen group filed suit.

In a consent decree to resolve the litigation, EPA divided CCW into two categories:

1. Fly ash, bottom ash, boiler slag, and FGD waste from the combustion of coal by

electric utility and independent power-producing facilities that is not co-managed

with other power plant wastes;

2. All CCW that is co-managed with other power plant wastes, including low

volume cleaning wastes, blow down and coal refuse and all remaining wastes

from the combustion of fossil fuels subject to RCRA Sections 3001(b) and

8002(n).36

EPA, when it finally submitted the RTC in 1988, determined that CCW did not warrant

regulation as hazardous waste under Subtitle C of RCRA.37

In a 1993 Regulatory Determination

(“RD”), EPA concluded that waste from Category 1 does not warrant regulation as hazardous

waste when managed alone, and therefore regulation under Subtitle C of RCRA is

inappropriate.38

Later, in a 1999 RTC, EPA concluded that waste from Category 2 should also be exempt

from regulation under Subtitle C.39

However, in 2000, EPA determined that national regulations

11

are appropriate under Subtitle D of RCRA for CCW placed in landfills and surface

impoundments, and possibly under certain sections of the Surface Mining Control and

Reclamation Act (SMCRA) and RCRA, for CCW placed in landfills and surface impoundments,

and placed in coal mines.40

EPA has not acted on the 2000 determination, and therefore no regulation under Subtitle D is

currently pending. In fact, since the determination, EPA has conducted a lengthy dialogue with

the utility industry’s consortium, the Utility Solid Waste Activities Group (“USWAG”), to create

a voluntary plan for CCW management. USWAG’s “Voluntary Action Plan” is a loosely

worded, unenforceable document that does not address the protective measures most necessary

for safe CCW disposal (e.g., frequent groundwater monitoring).

In January of 2007, a coalition of environmental agencies and organizations41

(Plains Justice

included) drafted a proposal for the Federal Regulation of Coal Combustion Waste to provide a

framework for appropriate federal regulation. This proposal has been submitted to EPA and is

appended to this report as a model for state reform.42

History of Iowa CCW

Regulation

Notwithstanding this long overdue national

movement for safer regulation of CCW disposal,

Iowa has yet to update its regulations to resemble

the more protective standards in use nationwide. In

2004, coal combustion in Iowa produced 1,260,000

short tons of CCW. Of that waste, 750,000 short

tons (around 60 percent) were designated for “beneficial use,” anything from the manufacture of

gypsum wallboard to filling abandoned quarries. Iowa also accepts CCW from other states for

disposal or “beneficial use.” Wisconsin is a large contributor, expected to grow larger if new

coal plant proposals become reality. The forty percent of CCW that is not “beneficially used”

goes to CCW landfills governed by 567 Iowa Administrative Code (“IAC”) 103.

Where CCW is allocated for “beneficial use” as fill material, the IAC has application,

record-keeping and reporting requirements for operators of fill sites. Iowa currently has nearly

two dozen sites approved for CCW “beneficial use.” Conditions vary greatly at these sites.

Some are abandoned quarries and some are working mines that fill empty mine “rooms” with

CCW on an ongoing basis. Other sites are one-time projects (e.g., road building or fill for

building projects). Some are closed, and others anticipate accepting CCW for decades to come.

Others, such as Waterloo South Quarry, are the proposed receptacles for the hundreds of

thousands of tons of CCW to be produced by new coal-fired power plants at Waterloo, Iowa and

Cassville, Wisconsin. Plant developers at Waterloo have repeatedly touted filling a quarry with

coal ash as an “environmental benefit” of the new plant.

Iowa is currently engaged in a rulemaking process to improve financial assurances for

disposal sites. The state is also reviewing solid waste regulations. Now is an ideal time to make

sure that all solid waste disposed in Iowa is subject to the same consistent level of protective

regulation.

Plant developers at Waterloo

refer to filling a quarry with

coal ash as an “environmental

benefit” of the new plant.

Current Iowa CCW

Regulations

As currently written, Iowa’s regulations for CCW disposal are weak in comparison to those of

other states and certainly in comparison to the federal regulations recommended to EPA by

national environmental organizations. The sanitary landfill CCW regulations at IAC § 567-103

(2007) are wholly inadequate to protect the health of Iowa’s citizens and the environment. CCW

approved for “beneficial use” under IAC § 567-108.4(4) (2007) is subject to even fewer

protective standards than CCW destined for landfills and is exempt from landfill permitting

requirements.

I. Sanitary Landfill CCW Regulations

Iowa’s Environmental Protection Commission regulates CCW sanitary landfills solely at IAC §

567-103 (2007).43

CCW sanitary landfills accept bottom ash, fly ash, slag and flue gas

desulfurization system material generated by the coal combustion process and associated air

pollution control equipment, plus any other pre-approved materials.44

A. Permitting Requirements

The following must be included in any application for a CCW landfill operating permit:

1. A completed application Form 50.542-1542;

2. A copy of the letter from the waste management assistance division approving the

comprehensive landfill operating plan;

3. Proof of legal entitlement to the property;

4. A topographical map of the landfill site and adjacent area (within 300 feet) that shows

existing wells and lakes;

5. The results of a minimum of three soil borings to determine the hydrogeologic conditions

and to determine the direction of groundwater flow throughout the site and the minimum

groundwater depth;

Page 21: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

14

6. An “adequate number” of representative groundwater sample results at a minimum of

three locations to characterize the groundwater quality. The analytical parameters

required to characterize the groundwater quality and establish a baseline for those

parameters are: arsenic, barium, beryllium, cobalt, copper, iron, lead, magnesium,

manganese, selenium, zinc, chlorides, and sulfate;

7. Construction drawings and specifications of the improvements and alterations that will

take place on the landfill site (i.e. roads, structures, drainage ways, etc.);

8. A copy of the local siting approval.45

Additionally, the site cannot be a wetland, be within a 100-year flood plain, have any sinkholes

or karst features, be located within 300 feet of a residential or commercial area (without the

written approval of the property owners), and must be a minimum of 5 feet above the high

groundwater table.46

These permitting requirements are inadequate to achieve any meaningful characterization

of the landfill site and the groundwater quality.

First, the permit requirements do not include an analysis of the quality of surface waters,

nor do they require the operator to identify any potential interconnections between aquifers and

surface waters. Without this essential information, it is impossible to ascertain the impact of

CCW disposal on the surface waters surrounding the landfill site.

Second, the baseline groundwater sampling requirements are too vague (e.g. the

requirement of an “adequate number” of samples) and lack certain features necessary to gain a

thorough understanding of the groundwater characteristics. For example, there are no specific

upgradient/downgradient sampling location requirements, no duration or frequency of sampling

requirements, and no requirement to update the site characterization as new information (i.e.

monitoring data) becomes available that indicates the hydrology has evolved or is influencing the

groundwater parameters.

The analytes sampled to determine baseline water quality do not include two well known

indicator parameters for ash contamination, boron and molybdenum. Ample research confirms

the leachability of boron and molybdenum from eastern and Midwestern coal ash. Dressen et al.

(1977) found that molybdenum was highly leachable from coal fly ash under alkaline conditions,

and Wu and Chen (1987) found that very high percentages of boron (58-88%) were leachable

from Illinois Basin bituminous coal ashes under alkaline conditions. Ainsworth and Rai (1987)

found molybdenum to be strikingly more concentrated in fly ash from eastern bituminous coal

compared to western subbituminous coal and lignite.

The state of Wisconsin uses boron as an indicator parameter for contamination at coal ash

landfills, and monitoring data from Wisconsin sites has repeatedly revealed high levels of boron

and molybdenum in groundwater at sites contaminated by coal ash. The failure to monitor for

boron and molybdenum leaves Iowa regulators less capable of distinguishing sources of

contamination at coal ash landfills such as the Cargill Gypsum/Fly Ash Landfill in Mahaska

County, where the operator is attributing high levels of sulfate, iron and manganese (many times

over secondary drinking water standards) in downgradient wells to degraded drainage from

previous coal mining at the site.

15

In addition, the applicant is not required to determine groundwater flow rates,

information that is fundamental to understanding the amount of water moving under a site and

pollutant transport times to human receptors such as drinking water or stock water wells or

irrigation pumping points. Furthermore, while the applicant must determine the direction of

groundwater movement, there are no details specifying the degree to which flow directions must

be understood, much less any requirement to map the direction of groundwater flow. In addition

to the lack of flow rates and vague requirement to determine flow direction, the requirement to

identify existing wells and lakes within 300 feet of the site on a topographical map will not

reliably reveal the nature, extent and proximity of human activities or ecological receptors to the

proposed landfill site. As a whole, these methods are unlikely to reveal the true risk of

unacceptable exposure to ash contaminants.

Last, there is no financial assurance requirement to cover monitoring, maintenance,

abatement of pollution, closure or postclosure of the landfill, although IDNR is in the process of

a rulemaking that should rectify this deficiency. Without a financial assurance requirement, the

State cannot be sure that operators will be responsible for any damage their landfills cause to any

groundwater, surface water, air, or the surrounding environment.

B. Design Criteria

Applicants for a CCW sanitary landfill permit must also submit a design plan for an operating

permit. In addition to certain fence and access road requirements, the CCW landfill site design

plan must include the following:

1. A method for ensuring protection of the groundwater and surface water;

2. A method of ash transportation that prevents blowing ash; and

3. A plan to divert surface runoff during the active life of the site and during the postclosure

period.47

These requirements are inadequate for the protection of public health and the

environment. While other states in the Midwest have developed thorough, detailed and

comprehensive isolation and cover requirements,48

Iowa’s regulations do not require any

particular isolation or cover system.

One sentence in the CCW disposal regulations directly addresses the protection of groundwater,

and that sentence proposes no specific standards or requirements.49

• There are no daily or intermediate cover requirements.50

• There are no liner permeability or thickness requirements, or even a requirement that an

operator must utilize a liner at all.

• There are no standards or requirements for a leachate collection system.51

Without these specific requirements to isolate CCW from groundwater, surface water, air, and

the surrounding environment, Iowans in the vicinity of coal ash landfills are not assured of

Page 23: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

16

adequate protection from the harmful heavy metal toxins that may escape CCW landfill sites in

the form of leachate and fugitive dust.

C. Monitoring Requirements

Iowa CCW landfill groundwater and surface water monitoring requirements are also inadequate

for the protection of public health and the environment. Within a year of initiating operations,

CCW sanitary landfill operators must commence a groundwater monitoring program. This plan

must be submitted to the appropriate department field office prior to initiating operations.52

The

monitoring program must include the following:

1. A minimum of 1 downgradient monitoring well installed within a year of initiating

operations (additional wells may be required);

2. Quarterly sampling of all monitoring wells within a year of commencing operations to

establish average baseline concentrations;

3. Annual sampling of all monitoring wells within one year of completing the quarterly

baseline monitoring;

4. Sampling for 3 consecutive months if a parameter is exceeded for the two most recent

years of data. If the average of the monthly samplings equals or exceeds the baseline

parameter, a site assessment may be required;

5. A report of the groundwater monitoring results must be submitted annually.53

Several aspects of these monitoring requirements are troubling. First, there is no requirement

for surface water monitoring. Without a requirement for surface water monitoring, any

contamination resulting from CCW leachate emanating to the surface may not be detected or, if

detected, may not be properly attributed to the CCW

landfill. The greater speed with which surface waters

travel, as compared to groundwater, and the threat that

high metals, pH and other pollutants in ash leachate

pose to aquatic life, wildlife and domestic animals,

make this deficiency particularly egregious.

Second, allowing the collection of monitoring data

to determine “baseline” concentrations after operations

at a landfill have commenced can result in the

collection of samples that do not reflect water quality

unaffected by waste disposal. This defeats the basic

objective of baseline monitoring, namely to establish

background water quality from before permit

operations with which to compare subsequent water

quality to determine if contamination from the waste is

occurring.

The determination of baseline water quality, water

flow directions and pathways, rates of flow and

locations of human and ecological receptors are basic

information that needs to be gathered for the regulatory

agency to make intelligent decisions to approve or

water quality, water flow

directions and pathways, rates

Without this information, cost

effective monitoring systems

that protect human health and

the environment with an

adequate margin of safety are

unlikely to be employed.

17

deny a permit for an ash landfill. Without this information, cost effective monitoring systems

that protect human health and the environment with an adequate margin of safety are unlikely to

be employed.

Third, only one downgradient monitoring well is required, while no upgradient monitoring

wells are required. Although the report’s authors find that most Iowa CCW landfills are being

required to install at least one upgradient monitoring well, this basic requirement is a standard

component in virtually all landfill regulations elsewhere and should not be determined on a

permit by permit basis. In addition to surface water monitoring points, more monitoring wells

should be required (at least one upgradient and at least three downgradient) to understand the full

impact of CCW leachate on groundwater. Monitoring of leachate quality from samples drawn

from leachate collection systems or from wells screened within the ash is also needed to

contextualize the constituents most likely to be found in downgradient waters from ash

contamination.

Fourth, the frequency of post-baseline groundwater monitoring and the initiation of

corrective action responses is severely inadequate and corrective action steps are not adequately

defined. Annual monitoring fails to account for different seasons in the hydrologic cycle when

aquifers are recharging or discharging and when water tables are fluctuating and greater

precipitation may dilute contaminant concentrations. Depending on when the sampling occurs,

the results can understate or overstate trends in concentrations or miss detection of a contaminant

entirely. Even if annual monitoring detects an increase in heavy metal toxins polluting Iowa

groundwater, nothing will be done until two consecutive years of sampling reveal an above

average number for the parameter in question. Only then will the operator be required to

implement a regime of sampling for three consecutive months.

Even then, if the average of those 3 month samples equals or exceeds the value that required

the monthly sampling, all that ”may” be done is a

“site assessment.” 54

Specific corrective actions and

the timing for executing them are not spelled out.

Thus, the operator will not be required by the

language of the regulation to take immediate

corrective action to abate proven contamination,

even though the CCW landfill has been polluting

the groundwater for well over two years.

As a basic recommendation, when a rise in

pollutant concentrations is detected, immediate

requirements to monitor from additional points and

for additional parameters would enhance efforts to

locate the source(s) of contamination within a

landfill. Such enhanced monitoring will

differentiate potential sources of contamination and

identify points where leachate is being generated

and migration is occurring.

The failure to require any of these steps in

regulations may leave residents near CCW landfills

with little assurance that contamination will be addressed before it harms them. In the worst

case scenario, the local community may be left entirely ignorant of emerging environmental

threats, becoming non-consenting participants in an experiment on their health.

18

D. Closure/Postclosure Requirements

Iowa CCW landfill closure/postclosure requirements are inadequate as well. The operator of a

CCW landfill does not have to submit a plan for post-closure (a closure plan requirement is not

specified) until 180 days prior to closure.55

The post-closure plan must contain the following:

1. The date of closure;

2. Actions that will be taken to close the site;

3. The parties responsible for postclosure care;

4. Final site contours and final cover design (which must consist of not less than 2 feet of

compacted soil and 1 foot of uncompacted soil capable of sustaining a growth of

common grass);

5. A slope design of not less than 3 percent or more than 25 percent;

6. A growth of common grasses to be established by the end of the first full growing season;

7. A minimum of 1 sample from each monitoring well shall be collected annually during the

post-closure period;

8. Annual inspection of the site, including a report on the findings and any corrective

actions taken.56

Post-closure actions are required for a minimum of 10 years following closure, although the

department may extend the monitoring and reporting period as needed.57

These closure/post-closure requirements do not adequately protect the health of Iowans and the

purity of Iowa’s ground and surface water. This inadequacy is manifest in several of the

regulation’s weaknesses:

1. the lack of mandatory final cover implementation date;

2. the short post-closure period (10 years);

3. the infrequency of sampling required;

4. the lack of surface water sampling;

5. the lack of specified corrective action standards and procedures; and

6. the lack of a financial assurance requirement.

The lack of a final cover implementation date means that CCW could go uncovered for extended

periods of time, creating a risk to the groundwater and nearby surface waters. Other states in the

Midwest have more stringent and specific time requirements for final cover implementation.58

The post-closure period is also too short to get a real sense of any potential long-term impact

CCW may have on the groundwater, surface water, and surrounding environment. It is

Page 26: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

19

important for the health of Iowans that the postclosure period be long enough to allow the

operator to assess with a high degree of accuracy the long-term effect of CCW.59

The lack of surface water sampling and infrequency of groundwater sampling ensure that

contamination will either go unnoticed or be approached with such lethargy that corrective action

will not halt contamination in time to avoid human and ecological damage. Indeed, whether any

corrective action will be required, even a site assessment for contaminant rises, is not clearly

spelled out. Finally, without a financial assurance requirement, the state may not be able to

enforce the post-closure care requirements and may be forced to shift the cost of monitoring and

clean-up to taxpayers. Upon finalization of new financial assurance requirements, they must

become part of all existing and new permits.

Groundwater Trends

at Iowa CCW

Landfills

Monitoring data from Iowa CCW landfills

demonstrate the potential for the CCW in these

facilities to pollute underlying groundwater. While

this report does not examine in detail the activities at

Iowa CCW landfills, the authors undertook a brief

examination of water quality at monitoring points at

these facilities. This analysis readily reveals higher

ash pollutant concentrations at downgradient points

than at upgradient points and rising concentrations at

downgradient points compared to concentrations at upgradient points that are usually static or

declining. The following are examples of these trends from three Iowa CCW landfills.

Figures 1 through 4 reflect iron, sulfate, magnesium and cobalt concentrations in the

shallow groundwater underneath the adjoining Cargill Sweeteners – North American Landfills

for CCW and gypsum near Eddyville in Mahaska County.60

According to reports in the permit

files from the landfill’s consultant, Howard R. Green Company, the original landfills for fly ash

(CCR) and gypsum were developed at this site in the late 1980s, approximately 10 to 15 years

after strip mining for coal ceased at the site. Gypsum was disposed in a cell on the western half

of the site from 1990 to 1991. A substantially larger amount of fly ash was deposited on the

eastern half of the site from 1990 to 2000. According to IDNR inspection reports, the amount of

fly ash disposed was approximately 20,000 to 30,000 tons per year.

Monitoring well MW-6 in Figures 1 through 4 is an upgradient point while monitoring

wells MW-10, 11, 12 and 13 are designated as downgradient points. These wells are screened in

mine spoils underneath a constructed groundwater drainage layer of sand, which in turn is under

a recompacted liner of “clay-rich mine spoils,” and a system of leachate collection pipes. The

upgradient and downgradient designations are corroborated by groundwater flow maps and water

level measurements in Annual Water Quality Reports from the Operator which place the water

elevations in MW-6 consistently above water elevations in the downgradient wells. For

example, water elevations (in feet above mean sea level) recorded in Annual Reports from

September 1995 through September 2005 were 7.6 to 40.8 feet higher in MW-6 than in MW-10,

MW-11, MW-12 and MW-13. Two other downgradient wells, MW-8 and MW-9 (unexamined)

were sampled in conjunction with MW-6 for the gypsum landfill.

Figure 1 reveals noticeably higher concentrations of iron in all downgradient wells, but

particularly MW-10 and MW-11, than have been measured in upgradient MW-6. The highest

measurement in MW-6 was 1.6 mg/L, while the highest measurements in MW-10 and MW-11

have been 3.6 and 3.9 mg/L respectively. Only three of 25 samples at MW-6 recorded iron

levels equal to or greater than five times the secondary Drinking Water Standard (“DWS”) of

0.30 mg/l. In contrast, 20 of 27 samples at MW-10 and 15 of 27 samples at MW-11 have

produced iron concentrations equal to or greater than five times the secondary DWS. There was

also an anomalously high measurement of 11 mg/L recorded at MW-13, but other measurements

for this well and those at MW-12 are in the same range as those at MW-6.

The operator maintains that higher iron levels at MW-11 and MW-12 are due to

“weathering of disturbed materials in the mine spoils.” The operator puts forward this same

assertion consistently for higher levels of manganese, sulfate, and cobalt at downgradient

monitoring wells at this site. However, this claim does not explain clearly rising trends in

average concentrations of these pollutants measured at downgradient monitoring wells that are

not seen at MW-6. Figure 1 reflects a doubling of average iron concentrations at MW-11 from

1990 to 2005.

If high iron at MW-11 were due simply to the ambient effects of mining which ended

thirty years ago at this site, one would not expect to find such a rising average concentration.

The oxidation and weathering of pyrites in the spoils should decline with time from the mining

as these constituents wash out of the system. The covering of the site with compacted spoils,

CCW and capping measures should have further reduced the atmospheric exposure needed for

weathering of spoils to produce such degraded mine drainage. Reductions in acid mine drainage

and acidity in both underground and surface mine sites with time has been substantively

documented in research and is a fundamental concept behind modern reclamation which seeks to

eliminate the atmospheric exposure that generates acid from mine spoils.61

In addition to much higher concentrations at downgradient points, Figure 2 demonstrates

the same rising trend in average sulfate concentrations is occurring at downgradient MW-12 but

not at upgradient MW-6. Access to monitoring data prior to 1999 for sulfate, not in the permit

file available at DNR’s main Des Moines records facility, would reveal if sulfate trends at other

downgradient monitoring points have been occurring. While sulfate concentrations at MW-6

have remained static, between the secondary DWS of 250 mg/L and US EPA’s health based

Drinking Water Advisory of 500 mg/L, the average sulfate concentration at MW-12 has risen to

approximately 3500 mg/L as of November 2005, 14 times the secondary DWS and seven times

the Drinking Water Advisory.62

The 2005 Annual Water Quality Report from Cargill also revealed manganese

concentrations of 8.9 mg/L at MW-10, 6.0 mg/L at MW-11, 2.6 mg/L at MW-12 and 0.712

annual sampling. Thus manganese ranged from just over twice the secondary DWS at MW-6 to

178 times the secondary DWS at MW-10. Levels at three of the four downgradient points also

exceeded all EPA (child and adult) Health Advisory Levels including the Drinking Water

Equivalent Level for manganese, which standards range from of 0.3 mg/L to 1.6 mg/L, while the

concentration at upgradient MW-6 remained below these health-based standards.

Much higher concentrations of magnesium at all downgradient wells than at upgradient

MW-6 provide additional evidence that ash is degrading groundwater at this site (see Figure 3).

While there is no drinking water standard, health advisory or drinking water advisory level for

magnesium, like calcium this metal occurs in large quantities and readily soluble concentrations

in many coal ashes and thus serves as a good indicator parameter for water contaminated by ash.

Presumably IDNR’s recognition of this fact is why it requires CCW landfills to monitor for

magnesium. The presence of high levels of sulfate and magnesium at downgradient monitoring

points appears to concern IDNR, which states in a May 8, 2006 letter to Cargill concerning the

2005 Annual Water Quality Report:

Page 31: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

24

In addition, the possibility that a release may have occurred at this site is

supported by the common occurrence of calcium sulfate and magnesium

sulfate in fly ash and by the detection of similar sulfate concentrations in

groundwater at other CCR landfills in the state.

Cargill appears to acknowledge the significance of high magnesium concentrations at the site in

the 2005 Report on page 11-2:

Magnesium was detected in all of the wells. Magnesium does not have a

MCL, SMCL, or HAL standard. The results were evaluated by comparing

the reported concentration to the average concentration from the most

recent two (2) years of data. The concentrations were above the two (2)

year average in all of the wells with the exception of MW-06. The

concentrations of magnesium detected in the wells ranged from 18.0 mg/L

in MW-06 to 310 mg/L in MW-10. Based on review of historical data, the

concentrations of magnesium in MW-13 may be indicative of an

increasing trend.

An increasing trend in average magnesium concentrations at MW-13 is confirmed in Figure 3

and might be confirmed at other monitoring points were there magnesium data available for

those points prior to Quarter 3 of 2000.

Figure 4 illustrates a rise in average cobalt concentrations in downgradient water at the Cargill

Landfill. Cobalt is a trace metal found in Iowa coal ashes (and many others) and monitored for

at Iowa CCW landfills. An Annual Water Quality Report filed for Permit No. 62-SDP-4-89P

states:

Analysis of Iowa coals shows the presence of sulfur, primarily from pyrite but also as

sulfate and in organic forms. These analyses also show the presence of cobalt,

manganese and iron in the ash from these coals (Hatch et al., 1984).

While cobalt can be radioactive and is much more toxic if so, it is usually found as a stable

metal. Cobalt is beneficial as part of Vitamin B12, but also harmful in small doses. The

International Agency for Research on Cancer (IARC) states that, “Cobalt is possibly

carcinogenic to humans” although this is based on studies of rodents breathing cobalt dust or

who had the metal placed directly into their bodies. Long term exposure of rodents to lower

levels of cobalt in food and drinking water has resulted in effects on the heart, liver, kidneys,

testes, blood and skin as well as behavior.63

26

While there is wide variation in standards for safe cobalt levels in water among states, the

latest measurements at MW-10 and MW-11 exceed Wisconsin’s groundwater standard and

drinking water standard for cobalt of 40 micrograms per liter (0.04 mg/L).

The figures below show similar degradation of the shallow groundwater underneath two other

Iowa CCW Landfills. Figures 5, 6 and 7 reflect rising iron and manganese concentrations and

notably higher sulfate concentrations respectively measured at downgradient monitoring wells

than at upgradient wells (and other downgradient wells) at the Grain Processing Corporation

Landfill. This facility occupies approximately 80 acres of a ravine fill site opening into a flood

plain near Muscatine in Louisa County.64

According to permit documents, “landfilling” has

been going on at this site since at least the mid-1960s.

Wells MW-2, MW-3 and MW-5 are designated upgradient points and MW-4, MW-15

and MW-16 are designated downgradient points. All monitoring wells at the site are screened in

shallow sand or in a deeper sand and gravel alluvial aquifer that is a regional water table in the

area. The designation of MW-5 is contradicted by permit materials which label it a

downgradient well in narratives and maps while monitoring reports identify MW-5 as an

upgradient point. Most notable are sharp rises in iron and manganese at downgradient MW-4 off

the northwestern corner of the site to concentrations that exceed the secondary DWS for iron by

28 times and manganese by 96 times. Also of note are rising sulfate concentrations at

downgradient MW-16 beyond the eastern boundary to three times the secondary DWS (250

mg/L) and 7 to 8 times higher than sulfate concentrations in the other monitoring wells.

Figures 8, 9 and 10 also reflect higher concentrations of iron, manganese and sulfate respectively

at downgradient points in groundwater underneath the CCR Landfill (Permit No. 29-SDP-3-82P-

ILF) at the Iowa Army Ammunition Plant in Des Moines County. The site occupies

approximately 7.5 acres. Although the data set extends for only 2-3 years and the site is small,

there is noticeably more degradation manifested at downgradient monitoring wells (MW-3-91,

MW-4-91d, MW-5-91, and MW-6-91) than at upgradient monitoring wells (MW-1-91 and MW-

2-91d). The “d” besides the monitoring label infers a deeper aquifer depth being monitored by

that well.

Monitoring data from Iowa CCW landfills indicates that additional safeguards are needed in

regulations as well as rigorous enforcement of those safeguards to stop contamination of shallow

groundwater by CCW that appears to be a routine occurrence at these “protected” sites.

II. “Beneficial Use” of CCWs

Not all CCW produced in or imported to Iowa winds up in a sanitary landfill. CCW is pre-

approved for “beneficial use” under Iowa Administrative Code § 567-108.4(4) (2007) and does

not require further approval from IDNR when used as designated by this regulation. Coal

combustion fly ash and flue gas desulfurization by-products may be used as follows:

1. Raw material in manufactured gypsum, wallboard, plaster, or similar product;

2. Raw material in manufactured calcium chloride;

3. Raw material in the manufacture of absorbents;

4. Fill material pursuant to IAC § 567-108.6(1) (defining requirements for fill material

use); or

5. Alternative cover material at a sanitary landfill pursuant to IAC § 567-108.8 (approving

use of alternative cover materials for sanitary landfills).65

Coal combustion fly ash or bottom ash or boiler slag may be used as follows:

1. Raw material in the manufacture of cement or concrete products;

2. Raw material to be used in mineral recovery;

Page 39: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

32

3. Raw material in the manufacture of asphalt products;

4. Raw material in plastic products;

5. Subbase for hard-surface road construction;

6. Soil stabilization for construction purposes;

7. Fill material pursuant to IAC § 567-108.6(1);

8. Alternative cover material at a sanitary landfill pursuant to IAC § 567-108.8.66

Coal combustion bottom ash may be used as follows:

1. Traction agent for surfaces used by vehicles;

2. Sandblasting abrasive.67

If CCW is to be used as fill material, the following measures are required:

1. Leachate characteristics of the solid by-product shall be measured by the synthetic

precipitation leaching procedure (SPLP, EPA Method 1312) and shall be less than or

equal to 10 times the maximum contaminant levels (MCL) for drinking water. Foundry

sand and coal combustion by-products may limit the SPLP analytes to total metals for

drinking water.

2. Total metals testing results, which shall include thallium, shall be consistent with the

department’s statewide standards for soil pursuant to IAC § 567-137. Arsenic levels shall

be consistent with the statewide standards for soil or the naturally occurring (i.e.,

baseline) arsenic levels of the soil, whichever are greater.

3. The solid by-product shall produce a fill that has a pH:

a. Greater than or equal to 5 and less than or equal to 8 if the fill may be used as a

growing media either now or in the future;

b. Greater than or equal to 5 and less than 12 if the fill is specifically intended not to

be uses as growing media either now or in the future. In this category of fill,

materials with a pH equal to or greater than 10 but less than 12 shall be used only

in areas where direct physical contact by humans for long periods of time is not

expected to occur.

c. For deep fills where only the surface may serve as growing media either now or in

the future, then at a minimum the top 3

feet shall have a pH greater than or

equal to 5 and less than equal to 8. Fill

material below the top 3 feet shall have

a pH greater than or equal to 5 and less

than or equal to 12.

4. The by-product shall not be placed in a

waterway or wetland or any waters of the state

or extend below or within 5 feet of the high

water table.

5. The by-product shall not be placed within the

100-year flood plain unless in accordance with

all local and department regulations including

IAC § 567-71.5 (regarding approval of waste or water treatment facilities).

Thus a laboratory leach test on

one sample of CCW and an

analysis of the pH and metals

content relative to soils from a

single sample of CCW are the

sole regulatory requirements

before large volumes of that

CCW can be used to fill a low-

lying area in Iowa.

Page 40: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

33

6. The by-product shall not be placed closer than 200 feet to a sinkhole or to a well that is

being used or could be used for human or livestock water consumption.

7. The by-product shall not be putrescible.68

Thus a laboratory leach test on one sample of CCW and an analysis of the pH and metals content

relative to soils from a single sample of CCW are the sole regulatory requirements before large

volumes of that CCW can be used to fill a low-lying area in Iowa. Normally the testing

requirements must be completed before commencing filling and in an annual report to IDNR.

However, file review indicates that variances to soil and pH standards are granted routinely.

More importantly, ample research has shown that laboratory leach tests such as the

Synthetic Precipitation Leaching Procedure (SPLP) do not provide a reliable indication of how

metals and other constituents in CCW will behave in the disposal environment. While this test

determines the quantity of inorganic constituents that readily leach out of a coal ash sample

under controlled laboratory conditions for short (18 hour) periods, it is not designed to simulate

actual conditions in sites where CCW is placed. Given the lack of any safeguards under Iowa’s

beneficial use policy separating the CCW fill sites from soils, rock and layers of earth or

preventing large quantities of rain water, snow melt or other precipitation from percolating

through these sites, the conditions in them will be geochemically much more complex than the

set conditions in the lab test.

Site placements will involve much larger volumes of coal ash in much more concentrated

environments for leaching, a variety of surrounding site materials, constant wetting and drying of

CCW that will vary throughout large deposits and changing chemistries of groundwaters and

leachates moving through the coal ash. Also missing from the SPLP is the ability to predict coal

ash leaching behavior over time. Coal ash placements will produce leachate over decades at

these sites, not hours. Different constituents in CCW and the surrounding earth will become

more or less soluble over time as factors such as oxidation/reduction potentials and pH change.

Not surprisingly, researchers at US EPA, the US Department of Energy, and numerous

universities have found that standard leaching tests (such as the SPLP) alone should not be relied

upon to predict the leaching behavior of numerous contaminants in coal ash and “may greatly

underestimate the actual leaching that will occur” at CCW disposal sites.69

A study of a bituminous fly ash disposal site revealed that several different leaching tests

failed to predict the contaminants ultimately found in monitoring wells.70

The study found that

leaching tests both over-predict and under-predict concentrations of pollutants and that results

should be field tested until the leaching characteristics of the particular ash in the site in question

are fully known. The study found that leach tests are unreliable field indicators “primarily

because these tests are not designed, and should not be used, to predict exactly the concentrations

of leachate components that will be found in the field.” 71

There are no regulatory requirements for environmental covenants or easements to prevent

future uses that might lead to human health impacts. There are no regulatory requirements for

pre-fill surface or groundwater baseline testing or for surface or groundwater monitoring after fill

activities have commenced.

Iowa’s ‘beneficial use’ regime in effect handles a toxic waste stream as if it were almost entirely

benign, creating the potential for a growing human health hazard.

34

A. Management Plans

All sites engaged in CCW beneficial uses listed in IAC § 567-108.4 are required to develop and

maintain a solid by-product management plan that satisfies the following requirements:

1. Lists the source(s) of the solid by-product;

2. Lists procedures for periodic testing of the solid by-product to ensure that the chemical

and physical composition has not changed significantly;

3. Provides a description of storage procedures, including:

a. Storage location(s);

b. Maximum anticipated inventory, including dimensions of any stockpiles;

c. Run-on and run-off controls, which may include a storm water National Pollution

Discharge Elimination System (“NPDES”) permit;

d. Maximum storage time, not to exceed six months unless authorized in writing by

the department.72

File review indicates that the quality and thoroughness of management plans vary widely, from

ring-bound documents that include test results, to one-page letters. Consistent standards are not

spelled out to ensure that periodic retesting occurs on a frequent enough basis to detect changes

in the physical and chemical composition of CCW before large quantities of the CCW are

dumped at fill sites. We were unable to locate any files that include NPDES permits. In general,

the management plans assert that run-off and run-on are not risks and do not address them. We

comment on one sample management plan below in a discussion of a Scott County, Iowa, site.

B. Records and Reporting

Any entity that engages in the beneficial use of CCW in Iowa must maintain all records related

to the management plan for a minimum of 5 years.73

Reporting is required as follows:

1. A copy of the management plan must be submitted to IDNR whenever that plan is

revised or within 60 days of the end of the calendar year, whichever is earlier;

2. Generators whose solid by-products are being beneficially used as fill material shall

submit to the department within 60 days of the end of each calendar year the following

information for each beneficial use project or activity:

a. The location of the project;

b. The tons of solid by-product used for the project.74

The only mention of Iowa in EPA’s “Coal Combustion Waste Management at Landfills and

Surface Impoundments, 1994-2004, Report”, notes that Iowa is one of 30 states that do not

exempt on-site CCW landfills from state solid waste permitting requirements. This is a

misleading categorization of Iowa’s permitting regime, because it gives the impression that

Iowa’s solid waste permitting laws apply to all CCW. On the contrary, if CCW is designated for

“beneficial use” in Iowa, a near total lack of state solid waste permitting requirements results.

Unfortunately, the EPA report did not review regulations governing the “beneficial use” of

CCWs, which are the source of greatest concern in Iowa.

Iowa Coal Combustion Waste Disposal

35

In addition, research for this report was complicated by the fact that IDNR does not have

basic permitting and enforcement data for this waste stream on its website. Paper files available

at the central records repository in Des Moines lack complete data even for sites where

monitoring has taken place. The lack of access to such basic information hampers citizen

involvement in the permitting and enforcement process. Public access is critical to each Iowa

resident’s ability to assess risks posed by existing and proposed land uses. Access to thorough

public environmental records is essential to good government at the local, county and state level.

Direct public access to such records also improves the incentives for regulatory compliance for

regulated entities.

C. Case Study 1 – Linwood Mining Beneficial Use Site, Scott County, Iowa

At the Linwood underground mining operation located north and west of Buffalo, Iowa, in Scott

County near the eastern border, fly ash is used to fill underground voids to stabilize the surface.

Linwood Mining and Materials Corporation (“Linwood”) collects fly ash as backhaul in their

product distribution to a number of coal combustion sites in Iowa, Indiana, and Wisconsin.75

Fly

ash used for backfilling mine chambers is stored onsite in contained compartments called pigs.

The management plan submitted by Linwood and the Waste Commission of Scott County and

accepted by IDNR appears inadequate even in relationship to the relatively minimal standards set

by the Code.

In response to the Code’s requirement for periodic testing, the management plan encloses

one set of test results of existing sources and proposes to test as new fuel sources are added or to

the extent that the fly ash can be considered a new source. How this will be determined, by

whom or by what standard, is not clear, but is a basic concern given the potential for multiple

different ashes from generators in several states to be disposed in this operation.

In what appears to be a violation of the plain language of IAC 567-108.6(1)(d), (e) and

(f), without any variance mentioned, the management plan states:

Fly ash backfilling operation of the rooms at the mine may occur within the

horizontal extent of the 100-year flood plain, are generally below the high water

table and may be within 200 feet of a sinkhole or well that is being used or could

be used for human or livestock consumption. The placement of fly ash in the

mine room is approximately 140 feet to 180 feet below the surface (Citations

omitted).76

The management plan does not give any additional information about the hydrogeology of the

site or explain why this situation should be considered legal.

Part of the submission from the operators is an application for a variance to allow for

beneficial use of CCW that exceeds state soil standards for beryllium and arsenic. The primary

justification offered is that the operator solidifies the fly ash by mixing it with water, then adding

lime kiln dust if necessary, to make the mixture “set up” in the mine. The variance petition

provides no further information about the stability or permeability of the substance created,

Page 43: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

36

although the petition asserts that “the material is not exposed to water,” suggesting that water

might affect it were water present.77

No test results on the resulting substance are included.

A September 15, 2005 request to accept CCW from Alliant Energy’s Nelson Dewey coal

fired plant at Cassville, Wisconsin, includes testing results indicating that the waste tests above

Iowa state soil standard limits for arsenic, vanadium, and “possibly beryllium,” although the

beryllium level detected is over twice the state soil standards limit.78

In three tests, the waste

tested from 19 to 38.1 mg/kg for arsenic, while the state standard for soil is 1.40 mg/kg.79

IDNR

granted a variance for beneficial use of this waste as minefill, relying on leachate tests dating

from 2001 in granting the June 2006 variance.80

Neither the beneficial use determination nor

the management plan for Linwood sets up any

enforceable schedule for composition testing in the

site or any requirement for groundwater monitoring.

Leachate tests more recent than from 2001 apparently

have not been required of the operator. IDNR and the

operator accept the “setting up” process that binds the

CCW in a “cementitious” state as sufficient

protection, without further analysis. Yet in evaluating

the variance request, IDNR Environmental Engineer

Senior Nina M. Koger states with regard to total

metals limits: “In some cases, the regulated limits are

set too high and there is no way to determine if the

results are actually less than the limit or not.”

The relevant section of the Code, IAC § 567-

108, provides no guidance on what conditions might

justify a variance allowing higher total metals limits

than those set by law. Part of the stated justification for the variance is that other sites have

received a similar variance, in spite of the fact that they do not “solidify” their fill. One of those

sites, Waterloo South Quarry Fill Reclamation, is discussed below.

D. Case Study 2 – Waterloo South Quarry Reclamation, Black Hawk County

Viewed from surface level (as pictured on the front of this report), Waterloo South Quarry is a

massive open pit with many ponds of standing water on a dry day. This quarry in northeastern

Iowa accepts CCW from some of Iowa’s best-known public and private institutions: the

University of Iowa, University of Northern Iowa, Iowa State University and John Deere

Foundry. University of Iowa fly ash and John Deere Foundry waste hold variances for

exceeding state standards.

Foundry sand goes into the quarry first, to a height of 12 feet from the natural surface.

Two feet of clay are added as an “aquitard.” Ash is then mixed with quarry rock to cover the

clay to within 2 feet of the natural surface. The final 2 feet are filled with vegetated topsoil. A

final letter in the file, changing the height of the foundry sand fill from 25 feet to 12 feet below

the surface, does not mention the clay cap. It is not clear whether this requirement still exists.

The file gives no indication of any groundwater monitoring at the site or any subsequent leachate

tests done on ashes once they are approved for disposal at this site. There is therefore no way to

determine whether any water contamination has resulted from CCW disposal at this site, and no

baseline from which to measure any future contamination, even if monitoring began today.

A September 15, 2005 request

to accept CCW from Alliant

Energy’s Nelson Dewey coal

fired plant at Cassville,

Wisconsin, includes testing

results indicating that the waste

tests above Iowa state soil

standard limits for arsenic,

vanadium, and “possibly

beryllium,” although the

beryllium level detected is over

Proposed Iowa CCW

Regulatory Reform

Iowa’s CCW disposal regulations need to improve

quickly in order to protect the health and well-being of

Iowans, and to keep our environment clean and safe.

Iowa is now home to a new 790MW coal-fired power

plant at Council Bluffs and state agencies have received

proposals for a 660MW plant at Marshalltown and a

750MW plant at Waterloo, each of which will add

thousands of tons of coal ash to Iowa disposal sites. In

light of these proposals for massive new coal plants that would dispose of their coal ash in Iowa,

new and more protective regulations are urgently needed.

The following proposed improvements to regulations for landfill sites constitute a framework

for comprehensive CCW regulations:

1. Improved site characterization is needed of disposal sites prior to permit approval. This characterization must include baseline surface water sampling and improved

baseline groundwater sampling in order to achieve a better understanding of the quality

of the water. At a minimum, monthly surface and groundwater quality samples at should

be collected that characterize the seasonal variation of surface and groundwater quality

throughout the entire hydrologic cycle in baseline sampling. These samples should be

collected from upgradient and downgradient monitoring points and upstream and

downstream monitoring points.

This characterization should also require mapping of the flow rate and direction of

groundwater and identify all interconnections between aquifers and groundwater and

surface waters on the site or in vicinity of the site. All of this information must be

gathered prior to approval of a facility’s permits and serve as the basis for approval of the

permit or disapproval of the site for waste disposal;

Iowa’s Coal Combustion Waste

disposal regulations need to

improve quickly to protect the

health and well-being of

Iowans, and to keep our

environment clean and safe.

39

2. Operators must characterize the chemical and physical properties of the CCW prior

to accepting it at their facilities, and must continue to characterize it as it evolves.

The characterization of the CCW should be integrated with the characterization of the site

so that disposal of wastes with known high potential to pollute at sites near human

receptors is avoided. 3. Operators must design a facility that is capable of limiting impacts to acceptable

levels during the lifetime of the disposal and through the closure/postclosure

periods. This design must include comprehensive liner, cover, and leachate collection

system requirements comparable to those of other states surrounding Iowa;

4. Increased monitoring is needed of the construction, operation, and performance of

the disposal site during its operation and after closure;

5. Groundwater and surface water monitoring are needed that will realistically detect

contamination from CCW leachate. This should include a minimum of 1

upgradient/upstream monitoring well, a minimum of 3 downgradient/downstream

monitoring wells (this should include the closest water-bearing zones to the bottom of fill

sites), and wells in proximity. In addition monitoring should document pollutant

concentrations emanating directly from within the waste.

Operators should be required to conduct at least quarterly sampling of all

monitoring wells during the life of the disposal site and during the closure/postclosure

periods to ensure that the groundwater and surface waters are safe from contamination.

Data from monitoring shall be assessed to assure that the initial conceptualization in

characterization of the site is updated as necessary so that monitoring systems remain

effective in measuring upgradient water quality and detecting contaminant migration

from the site;

6. Abatement of adverse impacts when they occur must be required by setting

standards of performance that trigger intervention both if standards are exceeded

and if standards will be exceeded. The procedure for assessing and abating pollution

should be clearly spelled out and should assure that pollution is abated as expeditiously as

possible.

7. The guarantee of financial assurance during the life of the disposal site and during

the closure/postclosure periods must be assured before permits for landfills are

approved.81

The danger posed by coal ash leachate does not disappear when coal ash is transported inside the

boundaries of a fill site. Evidence of harm from lax coal ash disposal is well established

throughout the country. No scientific basis exists for exempting fill sites from Iowa landfill

standards. Many fill sites in Iowa are in sand and gravel quarries or limestone quarries, a siting

choice that renders meaningless the limitation on placement of CCW five feet above the water

table, given that such sites are located in highly conductive aquifers. These are precisely the

sites that generate the highest human cancer risk according to the US EPA risk assessment just

completed in the August 2007 Notice of Data Availability.

40

Accordingly, we recommend that the Iowa Administrative Code be modified to remove

“fills, structural or otherwise, pursuant to IAC § 567-108.6(1), as a beneficial use of CCW

exempt from the landfill standards in IAC § 567-103.” In addition, the above deficiencies

provide ample basis for:

1. Halting further permitting, renewal or expansion of “fills” under Iowa Admin. Code § 567-

108.6(1);

2. Closing existing fill sites on the most expeditious, yet practicable schedule (within two

years);

3. Imposing immediate and long term monitoring at existing fill sites; and

4. Mandating cleanup of contamination detected at existing sites.

41

Conclusion

Iowa’s regulatory regime for CCW landfill sites and for “beneficial use” of CCW fill poses

significant risks of undetected environmental contamination, significant liability risks to fill site

operators, and significant health risks to Iowans. In light of the documented risks to human

health and the environment, we strongly recommend immediate cessation of “beneficial use” fill

permits and closure of such sites using the recommended practices for coal ash sanitary landfills.

National regulation, both of CCW landfill sites and “beneficial use” determinations, is desirable

because of the fluidity of CCW across state borders. A state by state project of regulatory reform

has the risk of commencing a race to the bottom, in which CCW would find its way to the most

loosely regulated state (which may be Iowa in the Midwest). Until national reform takes place,

Iowa must improve its CCW disposal regime to avoid becoming (or remaining) a regional net

recipient of this under-regulated hazardous waste stream.

Purpose of the Proposal

This proposal provides a framework for federal regulation of the waste generated by U.S.

coal-fired power plants. Its intent is to address, with nationally consistent, enforceable minimum

standards, the significant risks to human health and the environment posed by the disposal of

coal combustion waste (CCW).

The above-named groups submit this proposal as a starting point for an inclusive and

comprehensive discussion between EPA and environmental stakeholders.i We are submitting this

proposal with the hope that it will function as a working template for draft regulations to be

formulated by a committee established pursuant to the Federal Advisory Committee Act. It is

necessary for EPA to formally establish a committee comprised of interested and affected

stakeholders because, to date, EPA has sought almost exclusively the input of the regulated

community and consequently has failed to produce even draft regulations in the nearly seven

years following EPA’s Regulatory Determination.

In 2000, EPA made an explicit commitment to promulgate a rule pursuant to the

Resource Conservation and Recovery Act (RCRA) governing CCW.ii Since 2000, EPA has

conducted a long standing dialogue with the electric utilities industry and, in fact, invited their

consortium, the Utility Solid Waste Activities Group (USWAG)iii

, to submit a voluntary plan for

CCW management, in lieu of regulations, violating the clear directive of the 2000 Regulatory

Determination. In contrast, EPA did not solicit the submission of today’s proposal. Rather,

environmental stakeholders requested the opportunity to submit draft regulations after learning

that EPA was poised (1) to publish notice in the federal register of the electric utility industry’s

voluntary plan, and (2) to seek public comment on the option of abandoning federal regulation of

CCW. We greatly appreciate the opportunity to submit this proposal, but its placement in the

docket does not in any way indicate parity with the regulated community in terms of access and

consideration of our viewpoint by EPA.

We thus respectfully ask that EPA seriously and thoughtfully consider this proposal from

environmental groups and communities threatened or harmed by CCW. To this end, we ask for

the immediate establishment of a federal advisory committee whose charge is to produce

comprehensive enforceable federal regulations. To reiterate, the goal of these proposed

regulations is simply to initiate this dialogue. In order to move forward, the rulemaking process

must allow for extensive additional input from a variety of interested groups including, in

addition to environmental groups and affected communities, engineers, hydrogeologists, and

those, inside and outside of government, who may have creative approaches to achieving

environmental protection from CCW contamination.

Lastly, we cannot lose track of the fact that CCW currently disposed without adequate

safeguards poses an imminent and substantial endangerment to health and the environment at

numerous sites throughout the U.S. In view of this present threat, we ask that EPA use its

authority under Section 7003 of RCRA immediately to abate such hazards while the federal

rulemaking process is underway. EPA has the authority under Section 7003 to require ground

water monitoring, as well as remedial measures, at CCW disposal sites that threaten human

health or water resources. Because of the acknowledged damage to human populations, drinking

49

water sources and aquatic ecosystems, it is essential that EPA use this authority to prevent

further damage while developing this national rule.

The Need for This Proposal

In light of the significant risk to human health and the environment posed by improper

management of CCW, we ask that work begin immediately to draft federal regulations containing

adequate safeguards. Several recent EPA reports confirm the substantial, imminent and growing

risk posed by CCW and thus support the urgent need for federal regulations. Specifically:

• EPA’s draft Revised Risk Assessment for CCW (December 2006)iv found that people

living near CCW surface impoundments assume risks that exceed EPA cancer thresholds by

1000 times or more. EPA estimates that the excess cancer risk for adults and children drinking

groundwater contaminated with arsenic from CCW surface impoundments can be as high as 1 in

100 -- 10,000 times higher than EPA’s regulatory goal for reducing cancer risks.v Furthermore,

this draft Revised Risk Assessment confirms that “[t]here are ecological risks associated with

surface impoundments to terrestrial and aquatic communities primarily from selenium and

boron.”vi

• EPA’s 2006 report, entitled Characterization of Mercury-Enriched Coal Combustion

Residues from Electric Utilities Using Enhanced Sorbents for Mercury Control confirmed that

CCW leaches arsenic and selenium at levels of potential concern.vii

The report tested both

laboratory leachate and field leachate of CCW and found significant exceedances of MCLs for

arsenic and selenium in groundwater in a substantial percentage of the samples. In fact, the

concentrations of some samples approached 100 times the MCL. The report concludes that use

of activated carbon injection to capture mercury at coal-fired power plants substantially increases

the arsenic and selenium content of CCW. The report found, in addition, that CCW commonly

leached arsenic and selenium in excess of 10 times the MCL from both plants that employed

sorbent technologies and those that did not.

Also, according to this report and EPA’s Preamble to the National Emission Standards

for Hazardous Air Pollutants from the Portland Cement Manufacturing Industry published

December 20, 2006, sorbent injection processes significantly increase the mercury content of fly

ash.viii

Testing to date reveals that the median increase in mercury in fly ash is by a factor of 8.5

and, in one case, the mercury content increased by a factor of 70. Such increased mercury,

arsenic and selenium in fly ash also increase risks to human health via inhalation of fugitive dust.

In the 2000 Determination, EPA committed specifically to “reevaluat[ing] risks posed by

managing coal combustion solid wastes if levels of mercury or other hazardous constituents

change due to any future Clean Air Act air pollution control requirements for coal burning

utilities.”ix

It is critical that EPA mandate the use of air pollution control technologies, including

sorbent injection, to reduce hazardous emissions from coal-fired power plants. In conjunction

with their use, nevertheless, EPA must take action to ensure that the pollution reduction in power

plant air emissions is not transferred to land and water via the coal ash. Consequently, in view of

EPA’s own findings and explicit commitment, the agency must reassess risk to human health and

the environment from CCW enhanced by the use of pollution control devices.

• A 2006 report published by EPA and the U.S. Department of Energy (DOE), entitled

Coal Combustion Waste Management at Landfills and Surface Impoundments, 1994-2004, found

that states have not closed significant gaps in their regulation of CCW. In fact, the report’s

survey of surface impoundments and landfills permitted between 1994 and 2004 indicates that

the absence of state requirements imposing mandatory safeguards has resulted in disposal units

that lack basic safeguards. The report points out that 30% of the total coal-fired generating

capacity in the U.S. is in states “that potentially exempt CCW landfills from solid waste

permitting requirements and that exclude certain CCWs from all solid waste regulation.”x This

astounding statement most certainly underestimates the gap in state regulation of CCW, because

it does not account for the many states that exempt CCW from all solid waste regulation when

“beneficially used,” a term that frequently encompasses potentially dangerous fill projects for

roads, gravel pits, floodplains, floodways, hill sides, valleys and mines.xi

In view of EPA’s draft Revised Risk Assessment (cited above) that identifies significant

risk from leaking surface impoundments, the findings related to deficiencies in state laws

governing surface impoundments are particularly troubling. The DOE/EPA Report found that:

(i) Only one of the states surveyed had regulations requiring groundwater monitoring

at CCW surface impoundments.

(ii) Only 33% of the states surveyed had regulations requiring liners for surface

impoundments.

(iii) Only 14% of the states surveyed had regulations requiring leachate collection

systems for surface impoundments.

(iv) Only 20% of the states surveyed required corrective action and financial

assurance at CCW surface impoundments.

(v) Only 9% of the states surveyed had regulations requiring a solid waste permit for

all CCW surface impoundments.

The DOE/EPA report also found that states lacked regulations requiring many basic

safeguards for CCW landfills:

(i) 45% of the states surveyed do not require permits for all on-site CCW landfills.

Two states of the states surveyed do not require any solid waste permits for CCW

landfills.

(ii) 44% of the states surveyed did not have regulations requiring liners for CCW

landfills.

(iii) 33% of the states surveyed do not have regulations requiring groundwater

monitoring at CCW landfills.xii

(iv) No state surveyed had regulations requiring quarterly groundwater monitoring for

the active life of the disposal unit.xiii

(v) 71% of the states surveyed did not have regulations requiring leachate collection

systems for landfills.

(vi) No state surveyed passed more stringent regulations pertaining to liners,

groundwater monitoring, leachate collection or financial assurance for surface

impoundments or landfills since 1999.

51

Lastly, the report’s survey of new and expanded CCW landfills and surface

impoundments permitted between 1994 and 2004 indicates that substantial safeguards are still

not employed at many new or expanded units. The report found:

(i) 89% of the new surface impoundment permits lacked groundwater protection

standards.xiv

(ii) 89% of the new surface impoundment permits lacked requirements for closure

and post-closure.

(iii) 88% of the new surface impoundment permits lacked requirements for financial

assurance.

(iv) 88% of the new surface impoundments lacked solid waste permits.

(v) 38% of the new surface impoundment permits lacked groundwater monitoring

requirements.

• EPA’s most recent “Damage Case Assessment under RCRA for Fossil Fuel

Combustion Wastes,” dated August 2006, recognizes 24 proven damage cases -- more than

double the number of recognized damage cases cited in the 2000 Determination. Further, EPA

recognizes another 39 “potential” damage cases in the 2006 Assessment.xv

Given the serious

deficiencies in monitoring systems at most CCW sites, and the complete lack of monitoring at

many CCW sites, damage caused by lax management of CCW is highly likely to be

underestimated, as EPA conceded in its 2000 Determination.xvi

While we believe that EPA’s

damage case list represents only a small fraction of the contaminated sites caused by CCW, the

significant increase in the number of proven and potential damage cases speaks for itself. We

believe this sharp increase in officially recognized, documented damage cases to groundwater

and surface water by mismanaged CCW since 2000 requires an immediate response from EPA.

• DOE and the Energy Information Administration (EIA)’s 2007 Annual Energy Outlook

indicates that electricity production by coal is projected to increase almost 25 percent by 2020

and 64% by 2030.xvii

The increase in the production of coal ash is roughly proportional to the

increase in the use of coal for electric power. CCW generation will increase, therefore, at least

25 percent by 2020. Moreover, the increase in CCW volume is likely to be substantially greater,

because both the increased use of scrubbers on coal-fired power plants and the building of

numerous fluidized bed combustion plants (that produce up to 10 times more CCW than

conventional pulverized coal plants) will significantly boost the waste volume. According to

EPA, 129 million tons of CCW was produced in 2004. A sharp growth in the volume of this

immense waste stream, as well as its projected increase in toxicity, is a clear basis for immediate

regulatory action.

USWAG’s “Voluntary Action Plan”

This proposal stands in stark contrast to USWAG’s “Voluntary Action Plan” (VAP).

USWAG’s VAP contains six pages of loosely worded, wholly unenforceable voluntary actions

that, even if adopted in full today by all U.S. coal-fired power plants, would guarantee no

reduction of risk. While it is outside the scope of this document to critique the VAP, it is worth

noting that the agreement contains no enforceable conditions, signatories have up to five years

Page 59: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

52

before any groundwater monitoring is required at the majority of landfills and surface

impoundments, there is no prohibition on the most dangerous disposal practice identified by EPA

– the dumping of CCW in sand and gravel pits below the water table, nor is there a prohibition

on the construction of new surface impoundments, and the plan fails entirely to contain any

closure, post-closure and financial assurance requirements.

Simply put, USWAG’s VAP fails to address the critical safeguards required for safe

disposal of any solid waste. Thus contamination of drinking water supplies will likely continue

undetected and unabated, if not increase, given the pending construction of many new power

plants and the resulting substantial increase in CCW. Even if the VAP invited compliance with

appropriate safeguards, the fact remains that any voluntary plan, by definition, fails to provide

enforceable requirements and national consistency. In view of the abominable level of

safeguards on existing disposal units quantified in the 2000 Determination, which found that

only 57% of all landfills and 26% of all surface impoundments had liners, there is absolutely no

basis for EPA to rely on a voluntary plan for nationwide compliance. While the DOE/EPA

report asserts that some improvement in the use of safeguards has occurred at CCW units

permitted between 1994 and 2004, the 56 units surveyed by the report represent less than 10% of

all U.S. CCW disposal units. EPA has no data indicating that the use of safeguards has improved

whatsoever at the nation’s 600 existing CCW landfills and surface impoundments, only an

official admission that the damage from these units is more pervasive nationally than the agency

previously recognized (see above-cited 2006 Damage Case Assessment). Thus acceptance of a

voluntary agreement to deal with this management crisis consciously disregards the enormous

risk to human health and the environment posed by these operating units. It also disregards the

increased liability that will result from a major growth in the volume and toxicity of CCW

nationally without any enforceable standards in place to assure that citizens, their environment,

and their water supplies will be protected from imminent and substantial and endangerment.

This protection is required by RCRA and was promised by EPA in the 2000 Regulatory

Determination.

Summary of Proposed Regulations

A. Overview

The following proposed regulations constitute a framework for development of

comprehensive CCW regulations. The end goal is to produce regulations for the disposal of

CCW that prevents unacceptable impact to human health and the environment. To accomplish

this goal, the proposal must require that (1) CCW disposal facilities are located, designed and

operated to limit impacts to acceptable levels; (2) CCW disposal facilities are monitored to

demonstrate that they are limiting and will continue to limit impacts to acceptable levels; and (3)

CCW disposal facilities provide the financial means to remediate unacceptable impacts during

and after disposal operations.

To accomplish these objectives, the regulations must require the owners and operators of

all CCW disposal units to:

Page 60: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

53

(1) Characterize the disposal site at and around the facility prior to the

development of new CCW disposal units, during the operation of all CCW

disposal units and after closure of all disposal units.

(2) Characterize the chemical and physical properties of the CCW prior to

disposal, under disposal conditions and as the CCW evolves during disposal

operations and after closure.

(3) Design a facility capable of limiting impacts to acceptable levels during

operation of the unit and after closure.

(4) Monitor the construction, operation and performance of the facility during

operation of the unit and after closure.

(5) Monitor the impacts of the disposal unit, including instantaneous conditions,

historical trends, and future trends during operation of the unit and after

closure.

(6) Abate adverse impacts when they occur by setting standards of performance

that trigger intervention both if standards are exceeded and if standards will be

exceeded.

(7) Guarantee financial ability to intervene and remediate impacts during the

operation of the unit and after closure.

In addition, the proposed regulations must also guarantee public participation, public

access to information, and effective enforcement mechanisms, including the right to bring a

citizen suit, to ensure compliance with regulatory standards.

B. Specific Regulatory Provisions

The proposal submitted herein is patterned after EPA’s proposed rule, “Standards for the

Management of Cement Kiln Dust,” published by EPA on August 20, 1999.xviii

EPA described

this rule as a “creative, affordable, and common sense approach for the management of cement

kiln dust (CKD) waste under the Resource Conservation and Recovery Act.” The 1999 CKD

rule set forth numerous design and management standards, drawing primarily from the municipal

solid waste landfill regulations (40 CFR Part 258). In the CKD rule, EPA also proposed

”contingent” RCRA Subtitle C (hazardous waste) regulatory standards that would apply to CKD

in the event of substantial noncompliance with the Subtitle D standards. We believe a similar

framework is wholly appropriate for the regulation of CCW, as well. The following proposal,

however, does not contain provisions requiring CCW be subject to Subtitle C standards in the

event of substantial noncompliance with Part 253. We would, nevertheless, like to discuss the

addition of such regulatory provisions in the course of the CCW rulemaking.

Similarly, we have also deferred a discussion of waste characterization requirements for

CCW. In our view, most state CCW regulatory programs are barely able to meet the most basic

safeguards regarding the characterization, monitoring and abatement of pollution at CCW

disposal sites, much less competently implement major improvements in waste characterization

measures needed beyond the benchmark leach tests commonly used today. Because the evidence

demonstrates that even the most “benign” CCW, as indicated by standard laboratory leach tests,

has caused harm to the environment, we believe that the provisions in this proposal should apply

regardless of the waste characterization currently employed by state and federal agencies.

Page 61: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

54

However, we do believe that characterization of CCW must be further explored and view

characterization measures as potentially adding an additional degree of safety to the basic

standards of this proposal.

Specifically, our proposal contains the following provisions:

1. Location restrictions: Ban on disposal below the seasonal high groundwater level.

The proposed regulations include a ban on management of CCW in units whose base is

located below the seasonal high groundwater level. The seasonal high groundwater level is

defined as the natural level at which water stands in a shallow well open along its length and

penetrating the surficial deposits just deeply enough to encounter standing water at the bottom

when the aquifer is at its highest seasonal elevation. This specifically includes perched

groundwater. This restriction is necessary to protect human health and the environment because

of the damage caused by management of CCW at sites located below the natural water table.

2. Additional location restrictions: Prohibition on placement of CCW disposal units in

floodplains, wetlands, fault areas, seismic impact zones, unstable areas and karst

terrain.

The proposed regulations include a prohibition on locating new CCW units in

floodplains, wetlands, fault areas, seismic impact zones, unstable areas and karst terrain. For

existing units located in these areas, a demonstration must be made that such units are designed

in a way to prevent adverse impacts to the environment. If this demonstration cannot be made

the existing unit would have to close within two years of the effective date of the final rule.

3. Standards for protection of groundwater

The draft regulations propose that design criteria similar to those for municipal solid

waste landfills (MSWLFs) under the Subtitle D program (Solid Waste Disposal Facility Criteria,

56 FR 50978, October 9, 1991) be adopted with certain modifications for groundwater

monitoring and remediation. For the protection of groundwater, any new CCW management

unit or expansion of an existing unit must be constructed with a composite liner and a leachate

collection and removal system that is designed and constructed to maintain less than a 30 cm

depth of leachate over the liner. The composite liner must consist of two components; an upper

flexible membrane liner with a minimum thickness of 30 mil, and a lower component consisting

of at least two feet of compacted clay with a hydraulic conductivity of no more than 1 x 10(-7)

cm/sec. All waste management units must also apply suitable cover over exposed waste in a

manner designed to minimize surface water infiltration, leachate generation and the creation of

fugitive (airborne) releases from waste. Where required, based on site and waste characteristics,

additional requirements may be imposed on a case by case basis.

4. Requirements for groundwater monitoring and corrective action

The regulations propose that groundwater monitoring be required for all new and existing

CCW disposal units to detect the presence of CCW constituents in the groundwater. The

Page 62: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

55

groundwater monitoring system must include at a minimum one upgradient and three

downgradient wells screened in the shallow aquifer immediately below the waste disposal unit

and at least one well located in the waste to gather pore water quality and allow for rapid

identification and response to contamination of underlying groundwater. The downgradient

wells must be located not farther than 50 meters from the unit boundary at the relevant point of

compliance (POC) specified by the EPA Regional Administrator. The groundwater monitoring

system must be capable of ascertaining the quality of background groundwater that has not been

affected by releases from the unit and assessing the quality of groundwater passing the relevant

POC, as certified by a qualified groundwater scientist. The groundwater monitoring program

must include consistent procedures that are designed to ensure monitoring results that provide an

accurate representation of groundwater quality at the background and downgradient wells.

Because this proposal requires groundwater monitoring at new and existing CCW disposal units,

the rule effectively prohibits the location of such units in areas where subsurface conditions

prevent characterization and monitoring of subsurface contaminant migration.

The regulations propose that disposal facilities conduct quarterly monitoring for

"detection" parameters, which include common constituents of CCW. During “detection

monitoring,” groundwater monitoring results are measured against corrective action “trigger”

levels that are based on the highest pre-disposal concentrations of the constituents, as determined

by upgradient background monitoring and baseline monitoring that establishes background

quality at downgradient points prior to placement of CCW. If these trigger levels are exceeded, a

more extensive groundwater monitoring regime is required, which includes a much larger list of

assessment parameters monitored more frequently and from additional monitoring points.

Corrective action abatement steps must be taken if this ‘assessment monitoring”

determines that there is a statistically significant increase in pollutant concentrations above

background concentrations. The facility operator must complete an assessment and selection of

corrective action remedies within 120 days and begin abatement of the pollution within 60 days

of selecting the remedy. The objective of the remedy is to halt the spread of contamination and

restore background water quality at affected monitoring points. The remedy is deemed complete

when background water quality has been maintained for a period of three years.

5. Closure and Post Closure Care

The proposed regulations require that new and existing CCW disposal units, including

expansions and inactive units, be closed in accordance with specified standards and that units be

monitored and maintained after closure. Closure and post-closure plans describing these

activities are to be prepared to comply with a minimum set of procedural requirements.

The proposal requires that post-closure care be conducted for a period of 30 years after

the closure of each CCW disposal unit. Post-closure care consists of maintaining the

effectiveness of the final cap, continuing groundwater monitoring and leachate management, and

if necessary upgrading these activities, to control the formation and release of leachate into the

environment. Routine maintenance of the integrity of the final cap is necessary to prevent liquid

from penetrating into the closed landfill and creating the potential for leachate migration.

Iowa Coal Combustion Waste Disposal

56

6. Financial Assurance

The proposed regulations require a demonstration of financial assurance for the costs of

conducting closure, post-closure care and if applicable, corrective action for known releases.

The proposed financial assurance requirements are patterned after the financial assurance

provisions for municipal solid waste landfills under Subtitle D (see 258.71 to 258.75). The

purposes of the financial assurance are to ensure that the owner or operator of a CCW disposal

unit adequately plans for the future costs of closure, post-closure care and corrective action for

known releases, and to ensure that adequate funds will be available when needed to cover the

costs if the owner or operator is unwilling or unable to do so.

To demonstrate to the EPA Regional Administrator that it has planned for future costs,

written cost estimates must be prepared. These cost estimates would serve as the basis for

determining the amount of financial assurance that must be demonstrated. This proposal states

that that persons managing CCW in new and existing CCW disposal units, including expansions,

be required to demonstrate financial responsibility for closure, post-closure care, and corrective

action for known releases in an amount equal to the cost of a third party conducting these

activities. The cost estimates must be based on the cost of closing the CCW disposal unit at the

point of the unit's active life when the extent and manner of its operation would make closure the

most expensive. Similarly, cost estimates for post-closure care must include estimates for both

annual and periodic activities, and account for the most expensive costs of routine post-closure

care.

The proposal does not address the requirement to demonstrate financial assurance for

third party liability to compensate injured third parties. Such liability requirements are currently

required under RCRA Subtitle C for hazardous waste management facilities (see 40 CFR

264.147). Financial assurance for third-party liability benefits public health by providing the

incentive of lower insurance premiums resulting from improved facility design and operation.

This requirement should be considered and an analysis completed to determine its feasibility.

7. Implementation

Existing CCW disposal units, including expansions, would be required to be in compliance

with the groundwater monitoring requirements proposed under 253.40 within one year after the

effective date of the final rule. New CCW disposal units, including expansions, must be in

compliance with the groundwater monitoring requirements before CCW can be placed in the

unit. Groundwater monitoring shall be conducted throughout the active life and post-closure

care period of the CCW disposal unit.

8. Notification, Recordkeeping and Reporting

The proposed regulations require that information concerning CCW management be

retained in an operating record and be submitted to US EPA or an authorized state. In addition,

the rule proposes that all information contained in the operating record must be publicly

available. These requirements would ensure the public availability of basic types of information

that demonstrate compliance with the requirements of the proposed regulations.

Page 64: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

57

Record reviews are one of the ways EPA and citizens can ascertain whether a facility is

in compliance. Accordingly, in Sec. 253.23, a recordkeeping requirement ensures that a

historical record of CCW disposal unit performance is maintained at the facility and submitted to

the EPA Regional Administrator. The person managing CCW would be required to maintain and

submit the following records: (1) Any required demonstration, certification, finding, monitoring,

notification, testing, or analytical data under Subpart E of part 253; (2) required inspection

records, training procedures, and regulatory agency notification procedures; (3) required closure

and post-closure care plans and any monitoring or analytical data proposed under Secs. 253.50

and 253.51; and (4) any required cost estimates and financial assurance documentation proposed

in subpart G. All information in the operating record must be publicly available, and, as stated

above, EPA or an authorized state would receive copies of the documents. In addition,

documentation of groundwater monitoring that indicates exceedances of trigger levels must be

clearly set forth in notifications that are submitted to EPA (or the authorized state), the host

municipality, adjacent landowners, and the public.

9. Citizen Suits and Citizen Enforcement of Part 253 Standards

Part 253 provides citizens with the right to bring a citizen suit for the failure of any CCW

disposal unit to comply with Part 253 standards. In contrast, USWAG’s Voluntary Action Plan

provides no right of federal, state, or citizen enforcement of its provisions. EPA emphasized, in

its 2000 Determination, the importance of citizen enforcement and the inherent advantage of

subtitle D standards, which “would be applicable and enforceable by citizens as soon as the

federal rule becomes effective.”xix

Part 253 also affirms the right of citizens to bring an action

under section 7002 of RCRA, 42 U.S.C. §6972, to abate any pollution generated by CCW that

may create the threat of an imminent and substantial endangerment of health or the environment

or seek other relief related to the abatement of the threat.

In order to ensure the right of EPA to enforce the provisions of Part 253, as well as to

ensure the applicability of federal inspection authority of CCW units, it is necessary to provide in

the regulations that substantial noncompliance with specific Part 253 standards triggers Subtitle

C listing of CCW. While the regulation we are proposing does not propose this step, we

reiterate that it is essential to discuss this important contingency in course of comprehensive

CCW rulemaking.

10. Prohibition on the construction of new CCW surface impoundments and closure of

existing CCW surface impoundments

The draft regulations provide that after the effective date of the final rule construction of

new surface impoundments and the expansion of existing surface impoundments for the

management, storage or disposal of CCW shall be prohibited.

In addition, the disposal of CCW into existing surface impoundments shall cease within two

years of the final rule. The proposal requires monitoring to be established at existing surface

impoundments within one year of the effective date of the regulations and closure of CCW

Page 65: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

58

surface impoundments within two years, in accordance with all closure and post-closure

requirements set forth in Part 253.

Conclusion

This proposal lays the framework for a federal rule addressing the second largest

industrial solid waste stream in the U.S. Such a rule is long past due. The failure of EPA to

provide rules for safe disposal of coal ash has resulted in the poisoning of surface water and

groundwater in 23 states, by EPA’s own admission. As we approach the greatest increase in

coal-fired power plants in the history of this country, this is exactly the wrong time to acquiesce

and accept voluntary standards from an industry with a track record of poor waste management.

EPA must abide by its commitment in its 2000 Regulatory Determination to write a federal rule,

and it must bring those to the table with the will, expertise and commitment to assist in the effort.

Through a federal advisory committee, the process can be fair, open and collaborative.

Finally, because CCW currently disposed in dumps without adequate safeguards poses an

imminent and substantial endangerment to health and the environment at many sites, it is

appropriate that EPA immediately use its authority under Section 308(a) of the Clean Water Act

and Section 7003 of RCRA to require groundwater monitoring and cleanup at such sites. We

recommend that EPA survey its list of CCW damage cases, including potential and indeterminate

cases, and solicit input from stakeholders to identify disposal sites where monitoring or remedial

action is needed to quantify the threat to health and the environment. Information gathered from

this monitoring and remediation will help guide the federal rulemaking. Initiation of such

enforcement actions will make good on EPA’s explicit promise in its 2000 Determination,

wherein EPA stated, exactly twice, “As we proceed with regulation development, we will also

take enforcement action under RCRA section 7003 when we identify cases of imminent and

substantial endangerment.”xx

Subpart A--General Provisions

Sec. 253.1 Purpose, scope, and applicability.

(a) The purpose of this part is to establish minimum national criteria for all coal combustion

waste disposal units, including landfills and surface impoundments.

(b) Regulations in this part apply to any coal combustion waste (CCW) actively managed [after

the effective date of the final rule], and as otherwise specifically provided in paragraph (c) of this

section, including CCW managed in new CCW disposal units, existing CCW disposal units and

expansions of CCW disposal units.

(c) Regulations in this part also apply to CCW disposal units that stopped receiving waste before

[the effective date of the final rule], hereinafter “inactive units.” [In view of the large and diverse

universe of inactive units, it will be necessary to tailor the applicability of the closure and post-

closure requirements of Part 253 to these units. Factors that must be considered include the age

and condition of the unit, when CCW was last placed in the unit, and whether the unit has

already undergone closure pursuant to state requirements. These factors will be considered and

tailored requirements generated after further analysis.]

(d) The compliance date for all requirements of this part 253, unless otherwise specified, is [one

year after the effective date of the final rule].

CCW into or on any land or water so that such CCW or any constituent thereof may enter the

environment or be emitted into the air or discharged into any waters, including ground waters.

EPA Regional Administrator means the chief administrative officer of the EPA Region

responsible for implementing the Subtitle C solid waste permit program. This reference only

applies to a State that has not chosen to create a regulatory program under State law. In States

facility.

Run-on means any rainwater, leachate, or other liquid that drains over land onto any part of a

facility.

Saturated zone means that part of the earth's crust in which all voids are filled with water.

Storage means the containment of CCW on a temporary basis in such a manner as not to

constitute disposal of such waste.

Uniquely associated wastes are low volume wastes that are co-managed with coal combustion

waste including coal pile runoff, coal mill rejects/pyrites, air heater and precipitator washwater,

boiler fireside chemical cleaning waste, floor and yard drains and sumps, and waste treatment

sludge.

(d) For purposes of this Section:

(1)Unstable area means a location that is susceptible to natural or human-induced events or

forces capable of impairing the integrity of some or all of the landfill structural components

responsible for preventing releases from a landfill. Unstable areas can include poor

foundation conditions, areas susceptible to mass movements, and karst terrains.

(2) Structural components means liners, leachate collection systems, final covers, run-on/run-

off systems, and any other component used in the construction and operation of the CCW

disposal that is necessary for protection of human health and the environment.

(3) Poor foundation conditions means those areas where features exist which indicate that a

natural or human-induced event may result in inadequate foundation support for the structural

components of a CCW disposal unit.

(4) Areas susceptible to mass movement means those areas of influence (i.e., areas

characterized as having an active or substantial possibility of mass movement) where the

movement of earth material at, beneath, or adjacent to the CCW disposal unit, because of

natural or human-induced events, results in the downslope transport of soil and rock material

by means of gravitational influence. Areas of mass movement include, but are not limited to,

landslides, avalanches, debris slides and flows, soil fluction, block sliding, and rock fall.

Sec. 253.16 Karst terrains.

following factors, at a minimum, must be considered when determining whether a terrain is

karstic:

(1) On-site or local geologic or geomorphologic features;

(2) On-site or local soil conditions that may result in significant differential settling, collapse,

or puncture of a landfill liner;

(3) On-site hydrology, including the character and direction of ground-water flow and points

of discharge for the karst ground-water basin the facility may affect; and

(4) On-site or local human-made features or events (both surface and subsurface).

(c) The Regional Administrator must approve or disapprove any demonstration made pursuant to

Sec. 253.16(b) within 120 days of its submission. If the Regional Administrator does not

karst terrain must close the disposal unit in compliance with the applicable requirements of this

Page 78: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

71

Part within two years of that determination. All approved demonstrations must be maintained in

the operating record.

(d) For purposes of this Section:

(1) Karst terrains mean areas where karst landscape, with its characteristic hydrogeology

and/or landforms are developed. In karst terrain, ground-water flow generally occurs through

an open system with both diffuse and conduit flow end member components, and typically

has rapid ground-water flow velocities that exceed Darcian flow velocities. Composed of

limestone, dolomite, gypsum and other soluble rock, karst terrain typically has well

developed secondary porosity enhanced by dissolution. Landforms found in karst terrain

include, but are not limited to, sinkholes, sinking streams, caves, springs and blind valleys.

Karst terrains always include one or more springs for each ground-water basin, and

underground streams except where groundwater flow is diffuse or the host rock has

megaporosity.

(2) Structural components means liners, leachate collection systems, final covers, run-on/run-

off systems, and any other component used in the construction and operation of the CCW

disposal unit that is necessary for protection of human health and the environment.

(3) Conduit flow means nonlinear to turbulent groundwater flow through an integrated system

of conduits that behave hydraulically as a system of pipes. Conduit flow is typical of ground-

water flow through thick, massive soluble rock such as limestone, where ground water is

concentrated, flow is rapid and specific discharges are high. Turbulent conduit flow can be

initiated in fractures as thin as 5 to 10 millimeters.

(4) Darcian flow means groundwater flow which follows Darcy's law, where the specific

discharge is proportional to the hydraulic gradient. Darcian ground-water flow is typically

linear and laminar, travels from 1 x 10-11

to 1 x 10-12

centimeters per second, and is

characteristic of ground-water flow through granular porous media.

(5) Diffuse flow means groundwater flow that is laminar and slow (within the range of

Darcian flow velocities) through a system of joints and bedding planes that have had minimal

solution enlargement.

Subpart C--Additional Criteria

Sec. 253.20 Air criteria for temporary storage including storage in tanks, containers, or

buildings.

Administrator if a demonstration is made to the EPA Regional Administrator that the alternative

measures are at least as effective in controlling wind dispersal of CCW as the minimum

standards defined in paragraphs (a), (b), and (c) of this section. The person managing CCW must

place the demonstration in the operating record and provide a copy of the demonstration to the

EPA Regional Administrator.

Iowa Coal Combustion Waste Disposal

77

university programs that enable that individual to make sound professional judgments regarding

groundwater monitoring, contaminant fate and transport, and corrective action.

Sec. 253.41 Groundwater monitoring systems.

(a) A groundwater monitoring system must be installed that consists of a sufficient number of

wells and/or springs, installed at appropriate locations and depths, to yield groundwater samples

from the uppermost aquifer (as defined in Sec. 253.2) and any other aquifer that is hydrologically

connected to the uppermost aquifer or is otherwise vulnerable to contamination by the waste unit

based on the hydrologic characterization of the site. The groundwater monitoring system must

consist of sufficient monitoring points to detect degradation of groundwater quality that

originates from any point within the unit. The system must include, at a minimum, one

upgradient and three downgradient wells. Groundwater samples must:

(1) Represent the seasonal variation of head elevation and water quality of upgradient

groundwater that has not been affected by leakage from the unit being monitored.

(2) Represent the elevation and quality of leachate contained within the disposal unit

throughout the operation and post closure monitoring of the unit;

(3) Represent the quality of groundwater passing the relevant POC. The downgradient

monitoring system must be installed at the relevant POC (or at the waste management unit

boundary if deemed necessary by the EPA Regional Administrator to prevent offsite

migration of contaminants) that ensures timely detection of groundwater contamination in the

uppermost and any other affected aquifer.

(b) A groundwater monitoring system must be designed, installed, and operated to assure the

ability to detect changes in groundwater quality considering projected changes to the

hydrogeologic system at the facility during the construction, operation, and post-closure periods.

(c) A multi-unit groundwater monitoring system may be installed instead of separate

groundwater monitoring systems for each CCW disposal unit when the facility has several units,

provided the multi-unit groundwater monitoring system meets the requirement of paragraph (a)

of this section and will be as protective of human health and the environment as individual

monitoring systems for each CCW disposal unit, based on the following factors:

(1) Number, spacing, and orientation of the CCW disposal units;

(2) Hydrogeologic setting that exists during the construction, operation, and post-closure

periods; and

(3) Site history.

(d) Monitoring wells must be cased in a manner that maintains the integrity of the monitoring

well bore hole. This casing must be screened or perforated and packed with gravel or sand,

where necessary, to enable collection of ground-water samples. The annular space (i.e., the space

between the bore hole and well casing) above the sampling depth must be sealed to prevent

contamination of samples and the groundwater.

(1) The person managing CCW must notify the EPA Regional Administrator that the

documentation of design, installation, development, and decommission of any monitoring

Page 85: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

78

wells, piezometers and other measurement, sampling, and analytical devices has been placed

in the operating record; and

(2) The monitoring wells, springs, piezometers, and other measurement, sampling, and

analytical devices must be operated and maintained so that they perform to design

specifications throughout the life of the monitoring program.

(e) The number, spacing, and depths of monitoring systems shall be:

(1) Determined based upon site-specific hydrogeologic information that must include

thorough characterization of:

(i) Aquifer thickness(es), ground-water flow rate(s), groundwater flow direction(s)

including seasonal and temporal fluctuations in groundwater flow, and flow through

fractures or other pathways between aquifers; and

(ii) Saturated and unsaturated geologic units, disposed wastes, and fill materials overlying

the uppermost aquifer, materials comprising each potentially affected aquifer, and

materials comprising the confining unit defining the lower boundary of the uppermost

aquifer; including, but not limited to: thicknesses, stratigraphy, lithology, hydraulic

conductivities, porosities and effective porosities.

(2) Certified by a qualified groundwater scientist and approved by the EPA Regional

Administrator. Within 14 days of this certification, the person managing CCW must notify

the EPA Regional Administrator that the certification has been placed in the operating

record.

Sec. 253.43 Groundwater sampling and analysis requirements.

(a) The groundwater monitoring program must include consistent sampling and analysis

procedures that are designed to ensure monitoring results that provide an accurate representation

of groundwater quality at the upgradient and downgradient wells (and at springs respective to

site hydrogeology) installed in compliance with Sec. 253.41(a). The person managing CCW

must submit to the EPA Regional Administrator the sampling and analysis program

documentation and place this documentation in the operating record. The program must include

procedures and techniques for:

(1) Sample collection;

(2) Sample preservation and shipment;

(3) Analytical procedures;

(4) Chain of custody control; and

(5) Quality assurance and quality control.

(b) The monitoring program must include sampling and analytical methods that are appropriate

for groundwater sampling and that accurately measure hazardous constituents, ph, temperature,

specific conductivity and other monitoring parameters in groundwater and leachate samples.

Analyses shall be reported at detection limits at least 50 percent below the lower of health-based

or drinking water standards where such exist. Groundwater samples shall not be field-filtered

prior to laboratory analysis.

79

(c) The sampling procedures and frequency must ensure protection of human health and the

environment with an adequate margin of safety and be designed to reliably detect changes in

water quality and contamination from the waste disposal unit(s) before such contamination has

migrated beyond the property boundary of the waste disposal unit.

(d) Groundwater and leachate elevations must be measured in each well immediately prior to

purging, each time ground water is sampled. The rate and direction of groundwater flow must be

determined each time ground water is sampled. Groundwater elevations in wells that monitor the

same waste management area must be measured within a period of time short enough to account

for temporal variations in groundwater flow that could otherwise preclude accurate

determination of groundwater flow rate and direction.

(e) Baseline groundwater quality must be established in upgradient and downgradient well(s)

(and spring(s) if appropriate) for each of the monitoring parameters or constituents required in

the particular groundwater monitoring program that applies to the CCW disposal unit, as

determined under Sec. 253.44(a) or Sec. 253.45(a). Baseline monitoring must be sufficient to

track seasonal variability and consist of not less than quarterly sampling for a period of one year.

(f) The person managing CCW must determine whether or not there is an increase (increase or

decrease for pH) over baseline values for each parameter or constituent required in the particular

groundwater monitoring program that applies to the CCW disposal unit, as determined under

Sec. 253.44(a).

(g) In determining whether an increase (increase or decrease for pH) has occurred, the person

managing CCW must compare the groundwater quality of each parameter or constituent at each

monitoring well (and spring if appropriate) to the highest (highest and lowest for pH) recorded

baseline value of that constituent.

(h) Within 14 days after completing sampling and analysis, the person managing CCW must

determine whether there has been an increase (increase or decrease for pH) over baseline at each

monitoring well and spring.

Sec. 253.44 Detection monitoring program.

(a) Detection monitoring is required at CCW disposal units at all groundwater monitoring wells

(and springs if appropriate) defined under Sec. 253.41 (a). At a minimum, a detection monitoring

program must include the monitoring for the constituents listed in Appendix I to this part.

(1) The EPA Regional Administrator may establish an expanded list of indicator parameters

for a CCW disposal unit, in addition to the constituents listed in Appendix I to this part. In

determining additional parameters, the EPA Regional Administrator shall consider the

following factors:

(i) The types, quantities, and concentrations of constituents in wastes and leachate

managed at the CCW disposal unit;

(ii) The mobility, stability, and persistence of waste constituents or their reaction

products in any unsaturated zone(s) beneath the CCW disposal unit;

(iii) The detectability of indicator parameters, waste constituents, and reaction products

in the ground water; and

Page 87: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

80

(iv) The concentration or values and coefficients of variation of monitoring parameters

or constituents in the ground-water baseline.

(b) The monitoring frequency for all constituents listed in Appendix I to this part, or in the

alternative list approved in accordance with paragraph (a)(1) of this section, shall be sufficient to

track seasonal variability and not less than quarterly during the active life of the facility

(including closure) and the post-closure period.

(c) At least one sample from a leachate collection sump, and each upgradient and downgradient

well (and spring if appropriate) must be collected and analyzed during subsequent sampling

events.

(d) If the person managing CCW determines that the concentration of one or more of the

constituents listed in Appendix I to this part is higher (outside the range for pH) than the highest

(outside the range for pH) baseline value for that parameter at the POC, the person managing

CCW:

(1) Must, within 14 days of this finding, place a notice in the operating record indicating

which constituents have increased (outside the range for pH) over baseline levels, and notify

the EPA Regional Administrator of this finding. The documentation shall clearly indicate all

constituents that have increased over baseline and define the baseline for each identified

constituent;

(2) If the person managing CCW determines that there has been an increase above the

highest baseline value for any parameter (outside the range for pH), in any two sampling

events, he must establish an assessment monitoring program meeting the requirements of

Sec. 253.45 within 90 days, except as provided for in paragraph (d)(3) of this section.

(3) The owner/operator may demonstrate that the increase (outside the range for pH) resulted

from error in sampling or analysis. A report documenting this demonstration must be

certified by a qualified groundwater scientist and submitted to the EPA Regional

Administrator, as well as placed in the operating record. If the demonstration is approved by

the EPA Regional Administrator, the person managing CCW may continue detection

monitoring as specified in this Section. If, after 90 days, a successful demonstration is not

made, the person managing CCW must initiate an assessment monitoring program as

required in Sec. 253.45.

Sec. 253.45 Assessment monitoring program.

(a) Assessment monitoring is required whenever an increase over the highest (outside the

range for pH) baseline value has been detected for one or more of the constituents listed

in the Appendix I of this part during any two sampling events.

(b) Within 90 days of triggering an assessment monitoring program, and at least bimonthly

(every other month) thereafter, the person managing CCW must sample and analyze the

groundwater for constituents identified in Appendix VIII of Part 261 of this chapter as

well as aluminum, boron, chloride, chromium (hexavalent), copper, molybdenum, sulfate,

and zinc. A minimum of one sample from each downgradient well (and spring if

appropriate) must be collected and analyzed during each sampling event. The initial

sampling event for assessment monitoring will consist of the collection and analysis of

Page 88: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

81

four independent samples for all constituents in Appendix VIII of Part 261 as well as

aluminum, boron, chloride, chromium (hexavalent), copper, molybdenum, sulfate and

zinc from each upgradient and downgradient well (and spring if appropriate) to establish

existing concentrations for the constituents.

(c) The EPA Regional Administrator may increase the frequency for repeated sampling and

analysis for the set of constituents required by paragraph (b) of this Section, during the

active life (including closure) and post-closure care of the unit considering the following

factors:

(1) Lithology of the aquifer(s) and unsaturated zone(s);

(2) Hydraulic conductivity(ies) of the aquifer(s) and unsaturated zone(s);

(3) Ground-water flow rates;

(4) Minimum distance between upgradient edge of the CCW disposal unit and downgradient

monitoring well screen (minimum distance of travel);

(5) Hydrograph of springs if appropriate;

(6) Resource value of the aquifer; and

(7) Nature (fate and transport) of any constituents detected in response to this Section.

(d) After obtaining the results from the initial or subsequent sampling events required in

paragraph (b) of this Section, the person managing CCW must:

(1) Within 14 days, place documentation in the operating record identifying the constituents

that have been detected and their concentrations and submit such documentation to the EPA

Regional Administrator and to the host municipality in which the CCW disposal unit is

located. The documentation shall clearly specify each detected constituent along with the

baseline values for all detected constituents;

(2) Within 90 days, resample all wells (and springs if appropriate) specified by Sec.

253.41(a), conduct analyses for those constituents required by paragraph (b) of this Section,

and submit all analyses to the EPA Regional Administrator and host municipality as well as

record all concentrations in the facility operating record. At least one sample from each

upgradient and downgradient well (and spring if appropriate) must be collected and analyzed

during these sampling events.

(3) Establish upgradient concentrations for any constituents detected pursuant to paragraph (b)

or (d)(2) of this Section; and

(4) Determine whether or not there is a statistically significant increase over upgradient or

baseline values for each parameter or constituent required in the particular groundwater

monitoring program that applies to the CCW disposal unit, as determined under Sec.

253.44(a) or Sec. 253.45(a).

(e) The number of samples collected to establish groundwater quality data must be consistent

with the appropriate statistical procedures determined pursuant to paragraph (f) of this section.

The sampling procedures shall be those specified under Sec. 253.44 for detection monitoring,

Sec. 253.45 for assessment monitoring.

(f) One of the following statistical methods to be used in evaluating groundwater monitoring data

Page 89: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

82

must be specified in the operating record and submitted to the EPA Regional Administrator for

each hazardous constituent in addition to an evaluation of trend analysis that is sufficient to

account for seasonal or other temporal variations in the data. The statistical test chosen shall be

conducted separately for each hazardous constituent in each well (and spring if appropriate).

(1) A parametric analysis of variance (ANOVA) followed by multiple comparisons

procedures to identify statistically significant evidence of contamination. The method must

include estimation and testing of the contrasts between each compliance well's mean and the

upgradient mean levels for each constituent.

(2) An analysis of variance (ANOVA) based on ranks followed by multiple comparisons

procedures to identify statistically significant evidence of contamination. The method must

include estimation and testing of the contrasts between each compliance well's median and

the upgradient median levels for each constituent.

(3) A tolerance or prediction interval procedure in which an interval for each constituent is

established from the distribution of the upgradient data, and the level of each constituent in

each compliance well is compared to the upper tolerance or prediction limit.

(4) A control chart approach that gives control limits for each constituent.

(5) Another statistical test method that meets the performance standards of paragraph (h) of

this section. The person managing CCW must place a justification for this alternative in the

operating record and submit the justification to the EPA Regional Administrator of the use of

this alternative test. The justification must demonstrate that the alternative method meets the

performance standards of paragraph (h) of this section.

(g) Any statistical method chosen shall comply with the following performance standards, as

appropriate:

(1) The statistical method used to evaluate groundwater monitoring data shall be appropriate

for the distribution of chemical parameters or hazardous constituents. If the distribution of the

chemical parameters or hazardous constituents is shown by the person managing CCW to be

inappropriate for a normal theory test, then the data should be transformed or a distribution-

free theory test should be used. If the distributions for the constituents differ, more than one

statistical method may be needed.

(2) If an individual well comparison procedure is used to compare an individual compliance

well constituent concentration with upgradient constituent concentrations or a groundwater

protection standard, the test shall be done at a Type I error level no less than 0.01 for each

testing period. If a multiple comparisons procedure is used, the Type I experimental error rate

for each testing period shall be no less than 0.05; however, the Type I error of no less than

0.01 for individual well comparisons must be maintained. This performance standard does not

apply to tolerance intervals, prediction intervals, or control charts.

(3) If a control chart approach is used to evaluate groundwater monitoring data, the specific

type of control chart and its associated parameter values shall be protective of human health

and the environment. The parameters shall be determined after considering the number of

samples in the baseline data base, the data distribution, and the range of the concentration

values for each constituent of concern.

(4) If a tolerance interval or a predictional interval is used to evaluate ground-water

Page 90: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

83

monitoring data, the levels of confidence and, for tolerance intervals, the percentage of the

population that the interval must contain shall be protective of human health and the

environment. These parameters shall be determined after considering the number of samples

in the baseline data base, the data distribution, and the range of the concentration values for

each constituent of concern.

(5) The statistical method shall account for data below the limit of detection with one or more

statistical procedures that are protective of human health and the environment. Any practical

quantification limit (pql) that is used in the statistical method shall be the lowest concentration

level that can be reliably achieved within specified limits of precision and accuracy during

routine laboratory operating conditions that are available to the facility.

(6) The statistical method shall include procedures to control or correct for seasonal and

spatial variability as well as temporal correlation in the data.

(h) In determining whether a statistically significant increase has occurred, the person managing

CCW must compare the groundwater quality of each parameter or constituent at each monitoring

well (and spring if appropriate) designated pursuant to Sec. 253.41(a)(3) to the baseline value of

that constituent at that well (spring, if appropriate) and upgradient value of that constituent,

according to the statistical procedures and performance standards specified under paragraphs (f)

and (g) of this section.

(i) If the concentrations of all constituents listed in paragraph (b) are shown to be at or below

baseline values and upgradient values, using the statistical procedures in Sec. 253.45, for

consecutive sampling events spanning an entire hydrologic cycle, the person managing CCW

must notify the EPA Regional Administrator of this finding prior to returning to detection

monitoring.

(j) If one or more constituents listed in paragraph (b) are detected at statistically significant

action program is completed in accordance with Sec. 253.48(f).

(2) The owner or operator must increase the corrective action cost estimate and the amount of

financial assurance provided under paragraph (b) of this section if changes in the corrective

action program or CCW disposal unit conditions increase the maximum costs of corrective

action.

(3) The owner or operator may reduce the amount of the corrective action cost estimate and

the amount of financial assurance provided under paragraph (b) of this section if the cost

estimate exceeds the maximum remaining costs of corrective action. Within 14 days of

making an annual adjustment under paragraph (a)(1) of this section, the owner or operator

must notify the EPA Regional Administrator that the justification for the reduction or increase

of the corrective action cost estimate and the amount of financial assurance has been placed in

the operating record. The existing amount of financial assurance may not be reduced to a

lesser amount estimated for a reduced cost for corrective action until the reduction in cost is

approved by the EPA Regional Administrator.

(b) An owner or operator in a CCW disposal unit, if required to undertake a corrective action

program under Sec. 253.48 must establish financial assurance using the allowable mechanisms

defined under Sec. 253.64. An owner or operator in a CCW disposal unit must establish financial

assurance for all corrective action programs initiated during the active life of the unit, closure,

and post-closure care periods. The owner or operator must provide continuous coverage for

corrective action.

Sec. 253.64 Allowable mechanisms.

The mechanisms used to demonstrate financial assurance under this Section must ensure that

the funds necessary to meet the costs of closure, post-closure care, and corrective action for

known releases will be available whenever they are needed. Persons managing CCW must

choose from the options specified in paragraphs (a) through (j) of this section.

(a) Trust Fund.

(1) The owner or operator may satisfy the requirements of this section by establishing a trust

fund that conforms to the requirements of this paragraph. The trustee must be an entity which

has the authority to act as a trustee and whose trust operations are regulated and examined by

a Federal or State agency. A copy of the trust agreement must be placed in the facility's

operating record.

(2) Payments into the trust fund must be made annually by the owner or operator over the

term of the initial control mechanism or over the remaining life of the CCW disposal unit,

whichever is shorter, in the case of a trust fund for closure or post-closure care, or over one-

half of the estimated length of the corrective action program in the case of corrective action

for known releases. This period is referred to as the pay-in period.

(3) For a trust fund used to demonstrate financial assurance for closure and post-closure care,

the first payment into the fund must be at least equal to the current cost estimate for closure or

post-closure care, except as provided in paragraph (k) of this section, divided by the number

of years in the pay-in period as defined in paragraph (a)(2) of this section. The amount of

subsequent payments must be determined by the following formula:

Next Payment = [CE-CV]/Y

Where: CE is the current cost estimate for closure or post-closure care (updated for inflation

or other changes), CV is the current value of the trust fund, and Y is the number of years

remaining in the pay-in period.

(4) For a trust fund used to demonstrate financial assurance for corrective action, the first

payment into the trust fund must be at least equal to one-half of the current cost estimate for

corrective action, except as provided in paragraph (k) of this section, divided by the number

of years in the corrective action pay-in period as defined in paragraph (a)(2) of this Section.

The amount of subsequent payments must be determined by the following formula:

Next Payment = [RB-CV]/Y

Where: RB is the most recent estimate of the required trust fund balance for corrective action

(i.e., the total costs that will be incurred during the second half of the corrective action

period), CV is the current value of the trust fund, and Y is the number of years remaining in

the pay-in period.

(5) The initial payment into the trust fund must be made before the initial receipt of waste or

before two years elapse after the effective date of this rule, whichever is later; in the case of

closure and post-closure care, or no later than 120 days after the corrective action remedy has

been selected in accordance with the requirements of Sec. 253.48.

(6) If the owner or operator establishes a trust fund after having used one or more alternate

mechanisms specified in this Section, the initial payment into the trust fund must be at least

the amount that the fund would contain if the trust fund were established initially and annual

payments made according to the specifications of this paragraph and paragraph (a) of this

section, as applicable.

96

(7) The owner or operator, or other person authorized to conduct closure, post-closure care, or

corrective action activities may request reimbursement from the trustee for these

expenditures. Requests for reimbursement will be granted by the trustee only if sufficient

funds are remaining in the trust fund to cover the remaining costs of closure, post-closure

care, or corrective action, and if justification and documentation of the cost is placed in the

operating record. Prior to reimbursement, the owner or operator must notify the EPA Regional

Administrator that the documentation of the justification for reimbursement has been placed

in the operating record and that reimbursement has been received.

(8) The trust fund may be terminated by the owner or operator only if the owner or operator

substitutes alternate financial assurance as specified in this Section or if he is no longer

required to demonstrate financial responsibility in accordance with the requirements of Sec.

253.61(b), Sec. 253.62(b), or Sec. 253.63(b).

(b) Surety Bond Guaranteeing Payment or Performance.

(1) The owner or operator may demonstrate financial assurance for closure or post-closure

care by obtaining a payment or performance surety bond that conforms to the requirements of

this paragraph. The owner or operator may demonstrate financial assurance for corrective

action by obtaining a performance bond that conforms to the requirements of this paragraph.

The bond must be effective before the initial receipt of waste or before two years elapse after

[the effective date of this rule], whichever is later; in the case of closure and post-closure

care, the bond must be effective no later than 120 days after the corrective action remedy has

been selected in accordance with the requirements of Sec. 253.48. Within 14 days after

demonstrating financial assurance according to this section, the owner or operator must

notify the EPA Regional Administrator that a copy of the bond has been placed in the

operating record. The surety company issuing the bond must, at a minimum, be among those

listed as acceptable sureties on Federal bonds in Circular 570 of the U.S. Department of the

Treasury.

(2) The penal sum of the bond must be in an amount at least equal to the current closure,

post-closure care or corrective action cost estimate, whichever is applicable, except as

provided in paragraph (k) of this section.

(3) Under the terms of the bond, the surety will become liable on the bond obligation when

the owner or operator fails to perform as guaranteed by the bond.

(4) The owner or operator must establish a standby trust fund. The standby trust fund must

meet the requirements of paragraph (a) of this Section except the requirements for initial

payment and subsequent annual payments specified in paragraphs (a)(2), (3), (4) and (5) of

this section.

(5) Payments made under the terms of the bond will be deposited by the surety directly into

the standby trust fund. Payments from the trust fund must be approved by the trustee.

(6) Under the terms of the bond, the surety may cancel the bond by sending notice of

cancellation by certified mail to the owner and operator and to the EPA Regional

Administrator 120 days in advance of cancellation. If the surety cancels the bond, the owner

or operator must obtain alternate financial assurance as specified in this section.

Iowa Coal Combustion Waste Disposal

97

(7) The owner or operator may cancel the bond only if alternate financial assurance is

substituted as specified in this Section or if the owner or operator is no longer required to

demonstrate financial responsibility in accordance with Sec. 253.61(b), Sec. 253.62(b) or Sec.

253.63(b).

(c) Letter of Credit.

(1) The owner or operator may satisfy the requirements of this Section by obtaining an

irrevocable standby letter of credit that conforms to the requirements of this paragraph. The

letter of credit must be effective before the initial receipt of waste or before two years elapse

after the effective date of this rule, whichever is later; in the case of closure and post-closure

care, the letter of credit must be effective no later than 120 days after the corrective action

remedy has been selected in accordance with the requirements of Sec. 253.48. Within 14

days after obtaining a letter of credit, the owner or operator must notify the EPA Regional

Administrator that a copy of the letter of credit has been placed in the operating record. The

issuing institution must be an entity which has the authority to issue letters of credit and

whose letter-of-credit operations are regulated and examined by a Federal or State agency.

(2) A letter from the owner or operator referring to the letter of credit by number, issuing

institution, and date, and providing the following information: Name, and address of the

facility, and the amount of funds assured, must be included with the letter of credit in the

operating record.

(3) The letter of credit must be irrevocable and issued for a period of at least one year in an

amount at least equal to the current cost estimate for closure, post-closure care or corrective

action, whichever is applicable, except as provided in paragraph (k) of this Section. The letter

of credit must provide that the expiration date will be automatically extended for a period of

at least one year unless the issuing institution has canceled the letter of credit by sending

notice of cancellation by certified mail to the owner and operator and to the EPA Regional

Administrator 120 days in advance of cancellation. If the letter of credit is canceled by the

issuing institution, the owner or operator must obtain alternate financial assurance.

(4) The owner or operator may cancel the letter of credit only if alternate financial assurance

is substituted as specified in this Section or if the owner or operator is released from the

requirements of this Section in accordance with Sec. 253.61(b), Sec. 253.62(b) or Sec.

253.63(b).

(d) Insurance.

(1) The owner or operator may demonstrate financial assurance for closure and post-closure

care by obtaining insurance that conforms to the requirements of this paragraph. The

insurance must be effective before the initial receipt of waste or before two years elapse after

the effective date of the requirements of this rule, whichever is later; in the case of closure and

post-closure care, the insurance must be effective no later than 120 days after the corrective

action remedy has been selected in accordance with the requirements of Sec. 253.48. At a

minimum, the insurer must be licensed to transact the business of insurance, or eligible to

provide insurance as an excess or surplus lines insurer, in one or more States. Within 14 days

after obtaining insurance, the owner or operator must notify the EPA Regional Administrator

Page 105: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

98

that a copy of the insurance policy has been placed in the operating record.

(2) The closure or post-closure care insurance policy must guarantee that funds will be

available to close the CCW disposal unit whenever final closure occurs and/or to provide

post-closure care for the CCW disposal unit whenever the post-closure care period begins,

whichever is applicable. The policy must also guarantee that once closure or post-closure care

begins, the insurer will be responsible for the paying out of funds to the owner or operator or

other person authorized to conduct closure or post-closure care, up to an amount equal to the

face amount of the policy.

(3) The insurance policy must be issued for a face amount at least equal to the current cost

estimate for closure or post-closure care, whichever is applicable. The term face amount

means the total amount the insurer is obligated to pay under the policy. Actual payments by

the insurer will not change the face amount, although the insurer's future liability will be

lowered by the amount of the payments.

(4) A owner or operator, or any other person authorized to conduct closure or post-closure

care, may receive reimbursements for closure or post-closure expenditures, whichever is

applicable. Requests for reimbursement will be granted by the insurer only if the remaining

value of the policy is sufficient to cover the remaining costs of closure or post-closure care,

and if justification and documentation of the cost is placed in the operating record. Within 14

days after reimbursement, the owner or operator must notify the EPA Regional Administrator

that the documentation of the justification for reimbursement has been placed in the operating

record and that reimbursement has been received.

(5) Each policy must contain a provision allowing assignment of the policy to a successor

owner or operator. Such assignment may be conditional upon consent of the insurer, provided

that such consent is not unreasonably refused.

(6) The insurance policy must provide that the insurer may not cancel, terminate or fail to

renew the policy except for failure of payment of premium. The automatic renewal of the

policy must, at a minimum, provide the insured with the option of renewal at the face amount

of the expiring policy. If there is a failure to pay the premium, the insurer may cancel the

policy by sending notice of cancellation by certified mail to the owner and operator and to the

EPA Regional Administrator 120 days in advance of cancellation. If the insurer cancels the

policy, the owner or operator must obtain alternate financial assurance as specified in this

section.

(7) For insurance policies providing coverage for post-closure care, commencing on the date

that liability to make payments pursuant to the policy accrues, the insurer will thereafter

annually increase the face amount of the policy. Such increase must be equivalent to the face

amount of the policy, less any payments made, multiplied by an amount equivalent to 85

percent of the most recent investment rate or of the equivalent coupon-issue yield announced

by the U.S. Treasury for 26-week Treasury securities.

(8) The owner or operator may cancel the insurance policy only if alternate financial

assurance is substituted as specified in this Section or if the owner or operator is no longer

required to demonstrate financial responsibility in accordance with the requirements of Sec.

253.61(b), Sec. 253.62(b) or Sec. 253.63(b).

99

(e) Corporate Financial Test. The owner or operator that satisfies the requirements of this

paragraph may demonstrate financial assurance up to the amount specified herein:

(1) Financial Component.

(i) The owner or operator must satisfy one of the following three conditions:

(A) A current rating for its senior unsecured debt of AAA, AA, A, or BBB as issued by

Standard and Poor's or Aaa, Aa, A or Baa as issued by Moody's; or

(B) A ratio of less than 1.5 comparing total liabilities to net worth; or

(C) A ratio of greater than 0.10 comparing the sum of net income plus depreciation,

depletion and amortization, minus $10 million, to total liabilities.

(ii) The tangible net worth of the owner or operator must be greater than:

(A) The sum of the current closure, post-closure care, corrective action cost estimates

and any other environmental obligations, including guarantees, covered by a financial

test plus $10 million except as provided in paragraph (e)(1)(ii)(B) of this section.

(B) $10 million in net worth plus the amount of any guarantees that have not been

recognized as liabilities on the financial statements, provided all of the current closure,

post-closure care, and corrective action costs and any other environmental obligations

covered by a financial test are recognized as liabilities on the owner's or operator's

audited financial statements, and subject to the approval of the EPA Regional

Administrator.

(iii) The owner or operator must have assets located in the United States amounting to at

least the sum of current closure, post-closure care, corrective action cost estimates and any

other environmental obligations covered by a financial test as described in paragraph (e)(3)

of this Section.

(2) Recordkeeping and reporting requirements.

(i) As they become available, the owner or operator must place the following items into the

facility's operating record:

(A) A letter signed by the owner's or operator's chief financial officer that:

(1) Lists all the current cost estimates covered by a financial test, including, but not

limited to, cost estimates required for municipal solid waste management facilities

under 40 CFR Part 258, cost estimates required for UIC facilities under 40 CFR Part

144, if applicable, cost estimates required for petroleum underground storage tank

facilities under 40 CFR Part 280, if applicable, cost estimates required for PCB storage

facilities under 40 CFR Part 261, if applicable, and cost estimates required for

hazardous waste treatment, storage, and disposal facilities under 40 CFR Parts 264 and

265, if applicable; and

(2) Provides evidence demonstrating that the firm meets the conditions of either

paragraph (e)(1)(i)(A) or (e)(1)(i)(B) or (e)(1)(i)(C) and paragraphs (e)(1)(ii) and

(e)(1)(iii) of this Section.

(B) A copy of the independent certified public accountant's unqualified opinion of the

Page 107: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

100

owner's or operator's financial statements for the latest completed fiscal year. To be

eligible to use the financial test, the owner's or operator's financial statements must

receive an unqualified opinion from the independent certified public accountant. An

adverse opinion, disclaimer of opinion, or other qualified opinion will be cause for

disallowance, with the potential exception for qualified opinions provided in the next

sentence. The EPA Regional Administrator may evaluate qualified opinions on a case-

by-case basis and allow use of the financial test in cases where the EPA Regional

Administrator deems that the matters which form the basis for the qualification are

insufficient to warrant disallowance of the test. If the EPA Regional Administrator does

not allow use of the test, the owner or operator must provide alternate financial

assurance that meets the requirements of this Section.

(C) If the chief financial officer's letter providing evidence of financial assurance

includes financial data showing that owner or operator satisfies paragraphs (e)(1)(i)(B)

or (e)(1)(i)(C) of this section that are different from data in the audited financial

statements referred to in paragraph (e)(2)(i)(B) of this Section or any other audited

financial statement or data filed with the Securities and Exchange Commission (SEC)

then a special report from the owner's or operator's independent certified public

accountant to the owner or operator is required. The special report shall be based upon

an agreed upon procedures engagement in accordance with professional auditing

standards and shall describe the procedures performed in comparing the data in the

chief financial officer's letter derived from the independently audited, year-end financial

statements for the latest fiscal year with the amounts in such financial statements, the

findings of that comparison, and the reasons for any differences.

(D) If the chief financial officer's letter provides a demonstration that the firm has

assured for environmental obligations as provided in paragraph (e)(1)(ii)(B) of this

section, then the letter shall include a report from the independent certified public

accountant that verifies that all of the environmental obligations covered by a financial

test have been recognized as liabilities on the audited financial statements, how these

obligations have been measured and reported, and that the tangible net worth of the firm

is at least $10 million plus the amount of any guarantees provided.

(ii) The owner or operator must place the items specified in paragraph (e)(2)(i) of this

section in the operating record and notify the EPA Regional Administrator that these items

have been placed in the operating record before the initial receipt of waste or before two

years elapse after the effective date of this rule, whichever is later; in the case of closure,

and post-closure care, items specified in paragraph (e)(2)(i) of this section must have been

placed in the operating record no later than 120 days after the corrective action remedy has

been selected in accordance with the requirements of Sec. 253.48.

(iii) After the initial placement of items specified in paragraph (e)(2)(i) of this section in

the operating record, the owner or operator must annually update the information and place

updated information in the operating record within 90 days following the close of the

owner or operator's fiscal year. The EPA Regional Administrator may provide up to an

additional 45 days for a owner or operator who can demonstrate that 90 days is insufficient

time to acquire audited financial statements. The updated information must consist of all

items specified in paragraph (e)(2)(i) of this section.

Iowa Coal Combustion Waste Disposal

101

(iv) The owner or operator is no longer required to submit the items specified in paragraph

(e)(2) of this section or comply with the requirements of this paragraph when:

(A) The person substitutes alternate financial assurance as specified in this section

that is not subject to these recordkeeping and reporting requirements; or

(B) The person is released from the requirements of this section in accordance with

Sec. 253.61(b), Sec. 253.62(b), or Sec. 253.63(b).

(v) If the owner or operator no longer meets the requirements of paragraph (e)(1) of this

section, the owner or operator must, within 120 days following the close of the owner or

operator's fiscal year, obtain alternative financial assurance that meets the requirements of

this section, place the required submissions for that assurance in the operating record, and

notify the EPA Regional Administrator that the owner or operator no longer meets the

criteria of the financial test and that alternate assurance has been obtained.

(vi) The EPA Regional Administrator may, based on a reasonable belief that the owner or

operator may no longer meet the requirements of paragraph (e)(1) of this section, require at

any time the owner or operator to provide reports of its financial condition in addition to or

including current financial test documentation as specified in paragraph (e)(2) of this

section. If the EPA Regional Administrator finds that the owner or operator no longer

meets the requirements of paragraph (e)(1) of this section, within 120 days of this finding

the owner or operator must provide alternate financial assurance that meets the

requirements of this section.

(vii) Calculation of costs to be assured. When calculating the current cost estimates for

closure, post-closure care, corrective action, or the sum of the combination of such costs to

be covered, and any other environmental obligations assured by a financial test referred to

in paragraph (e) of this section, the owner or operator must include cost estimates required

for coal combustion waste management facilities under this part, as well as cost estimates

required for the following environmental obligations, if the person assures them through a

financial test: obligations associated with UIC facilities under 40 CFR Part 144, petroleum

underground storage tank facilities under 40 CFR Part 280, PCB storage facilities under 40

CFR Part 261, and hazardous waste treatment, storage, and disposal facilities under 40

CFR Parts 264 and 265.

(f) Corporate Guarantee.

(1) The owner or operator may meet the requirements of this section by obtaining a written

guarantee. The guarantor must be the direct or higher-tier parent corporation of the owner

or operator, a firm whose parent corporation is also the parent corporation of the owner or

operator, or a firm with a ``substantial business relationship'' with the owner or operator.

The guarantor must meet the requirements for owners or operators in paragraph (e) of this

section and must comply with the terms of the guarantee. A certified copy of the guarantee

must be placed in the facility's operating record along with copies of the letter from the

guarantor's chief financial officer and accountants' opinions. If the guarantor's parent

corporation is also the parent corporation of the owner or operator, the letter from the

guarantor's chief financial officer must describe the value received in consideration of the

guarantee. If the guarantor is a firm with a ``substantial business relationship'' with the

Page 109: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

102

owner or operator, this letter must describe this ``substantial business relationship'' and the

value received in consideration of the guarantee.

(2) The guarantee must be effective and all required submissions placed in the operating

record before the initial receipt of waste or before the effective date of the requirements of

this section, whichever is later, in the case of closure and post-closure care, or in the case

of corrective action no later than 120 days after the corrective action remedy has been

selected in accordance with the requirements of Sec. 253.48.

(3) The terms of the guarantee must provide that:

(i) If the owner or operator fails to perform closure, post-closure care, and/or corrective

action of a facility covered by the guarantee, the guarantor will:

(A) Perform, or pay a third party to perform, closure, post-closure care, and/or

corrective action as required (performance guarantee); or

(B) Establish a fully funded trust fund as specified in paragraph (a) of this section in

the name of the owner or operator (payment guarantee).

(ii) The guarantee will remain in force for as long as the owner or operator must comply

with the applicable financial assurance requirements of this Subpart unless the guarantor

sends prior notice of cancellation by certified mail to the owner or operator and to the EPA

Regional Administrator. Cancellation may not occur, however, during the 120 days

beginning on the date of receipt of the notice of cancellation by both the owner or operator

and the EPA Regional Administrator, as evidenced by the return receipts.

(iii) If notice of cancellation is given, the owner or operator must, within 90 days

following receipt of the cancellation notice by the owner or operator and the EPA Regional

Administrator, obtain alternate financial assurance, place evidence of that alternate

financial assurance in the facility operating record, and notify the EPA Regional

Administrator. If the owner or operator fails to provide alternate financial assurance within

the 90-day period, the guarantor must provide that alternate assurance within 120 days of

the cancellation notice, obtain alternative assurance, place evidence of the alternate

assurance in the facility operating record, and notify the EPA Regional Administrator.

(4) If a corporate guarantor no longer meets the requirements of paragraph (e)(1) of this

section, the owner or operator must, within 90 days, obtain alternative assurance, place

evidence of the alternate assurance in the facility operating record, and notify the EPA

Regional Administrator. If the owner or operator fails to provide alternate financial assurance

within the 90-day period, the guarantor must provide that alternate assurance within the next

30 days.

(5) The owner or operator is no longer required to meet the requirements of paragraph (g)

of this section when:

(i) The owner or operator substitutes alternate financial assurance as specified in this

section; or

(ii) The owner or operator is released from the requirements of this section in

accordance with Sec. 253.61(b), Sec. 253.62(b), or Sec. 253.63(b).

(g) State-Approved Mechanism. In an authorized State, the owner or operator may satisfy the

Page 110: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

103

requirements of this section by obtaining any other mechanism that meets the criteria specified in

paragraph (j)(1) Of this section, and that is approved by the State Director.

(h) State Assumption of Responsibility. If the State Director either assumes legal responsibility

for the person's compliance with the closure, post-closure care and/or corrective action

requirements of this part, or assures that the funds will be available from State sources to cover

the requirements, the owner or operator will be in compliance with the requirements of this

section. Any State assumption of responsibility must meet the criteria specified in paragraph

(j)(1) of this section.

(i) Use of multiple mechanisms. The owner or operator may demonstrate financial assurance for

closure, post-closure, and corrective action, as required by Sec. 253.61, Sec. 253.62, and Sec.

253.63 by establishing more than one mechanism per facility, except that mechanisms

guaranteeing performance rather than payment, may not be combined with other instruments.

The mechanisms must be as specified in paragraphs (a), (b), (c), (d), (e), (f), (g), (h), and (i) of

this section, except that financial assurance for an amount at least equal to the current cost

estimate for closure, post-closure care, and/or corrective action may be provided by a

combination of mechanisms rather than a single mechanism.

(j) The language of the mechanisms listed in paragraphs (a), (b), (c), (d), (e), (f), (g), (h), and (i)

of this section must ensure that the instruments satisfy the following criteria:

(1) The financial assurance mechanisms must ensure that the amount of funds assured is

sufficient to cover the costs of closure, post-closure care, and corrective action for known

releases when needed;

(2) The financial assurance mechanisms must ensure that funds will be available in a timely

fashion when needed;

(3) The financial assurance mechanisms must be obtained by the owner or operator by the

effective date of these requirements or prior to the initial receipt of solid waste, whichever is

later, in the case of closure and post-closure care, and no later than 120 days after the

corrective action remedy has been selected in accordance with the requirements of Sec.

253.48, until the owner or operator is released from the financial assurance requirements

under Secs. 253.61, 253.62 and 253.63.

(4) The financial assurance mechanisms must be legally valid, binding, and enforceable under

State and Federal law.

Sec. 253.65 Discounting.

The EPA Regional Administrator may allow discounting of closure cost estimates in Sec.

253.61(a), post-closure cost estimates in Sec. 253.62(a), and/or corrective action costs in Sec.

253.63(a) up to the rate of return for essentially risk free investments, net of inflation, under the

following conditions:

(a) The EPA Regional Administrator determines that cost estimates are complete and accurate

and the owner or operator has submitted a statement from a Registered Professional Engineer so

stating;

(b) The EPA Regional Administrator finds the facility in compliance with applicable and

Page 111: November 2007 - Plains Justiceplainsjustice.org/files/CoalCombustionWasteReport/CCW Report... · tons of sulfur dioxide, 10,200 tons of nitrogen oxide, 3.7 million tons of carbon

Iowa Coal Combustion Waste Disposal

104

appropriate permit conditions;

(c) The EPA Regional Administrator determines that the closure date is certain and the owner or

operator certifies that there are no foreseeable factors that will change the estimate of site life;

and

(d) Discounted cost estimates must be adjusted annually to reflect inflation and years of

remaining life.

NOTES

i Due to the very short time period provided by EPA to submit this proposal, we have not attempted to address all

aspects of CCW management nor have all identified issues been fully resolved. For example, this proposal does not

address the various uses of CCW that can cause serious contamination of water resources, such as the use of coal ash

for fill and road base. The absence of provisions addressing this and other CCW hazards should not be construed as

an absence of concern, nor should it be construed to mean that regulations are not required to address those issues.

Given the time and opportunity, we are very interested in working with EPA to fill all gaps remaining in this

proposal.

ii On April 24, 2000, EPA acknowledged in its Regulatory Determination that “coal combustion wastes could pose

risks to human health and the environment if not properly managed” and “national regulations under subtitle D of

RCRA are warranted for coal combustion wastes when they are disposed in landfills or surface impoundments.”

70 Fed. Reg, 32214 at 33214. Hereinafter this document is referred to as “EPA 2000 Determination.”

USWAG is a consortium of approximately 80 utility operating companies comprising more than 85% of total U.S.

electric generating capacity.

iv In January 2007, EPA denied a FOIA request from Earthjustice for the final Revised Risk Assessment. The denial

is currently under appeal. Earthjustice did receive in a synopsis of the draft Revised Risk Assessment, and, as of the

date of this document, Earthjustice has received no indication from EPA that the conclusions of the draft Revised

Risk Assessment have changed.

v EPA summarized the draft Revised Rick Assessment as follows: “The primary risk to groundwater is from

Arsenic. Risk exceedances due to arsenic (groundwater to drinking water pathway) are from 10(-2) to 10(-3) for

surface impoundments and 10(-4) for landfills.” From a document entitled, “Coal Combustion Waste (CCW)

Rulemaking Early Guidance Meeting, Briefing: Marcus Peacock, Deputy Administrator, EPA, July 27, 2006,”

See, for example, the Indiana statutory provision that explicitly prohibits the Solid Waste Management Board, the

rulemaking body responsible for environmental regulation of solid wastes, from developing any regulations

restricting the use of power plant waste as fill. See IC 13-19-3-3(2)(E).

xii

Texas, the state that generates the largest amount of CCW in the U.S., does not require groundwater monitoring.

xiii

The only surveyed state that approached this benchmark was Pennsylvania, which requires “no shorter than”

quarterly groundwater monitoring for indicator parameters but ‘no shorter than” annual monitoring for metals and

volatile organic compounds.

xiv Groundwater protection requirements are defined in the report as contaminant concentrations in groundwater that

cannot be exceeded. xv

“Potential damage cases,” by EPA’s definition, constitute sites at which groundwater or surface water is

contaminated by CCW leachate but where the agency has no evidence of migration beyond the property boundary or

where contaminants are not listed as primary contaminants under the Safe Drinking Water Act. “Potential” does not

mean that contamination is not proven.

xvi

EPA stated, “ Given the volume of coal combustion wastes generated nationwide (115 million tons) and the

numbers of facilities that currently lack some basic environmental controls, especially groundwater monitoring,

other cases of proven and potential damage are likely to exist.” 2000 Determination at 32216.
