Re: April 19-20, 2012 Clean Water Act Inspection

Dear CAPT Williamson:

Enclosed is the January 29, 2013 report for our April 19-20, 2012 inspection of the

NAVFAC-HI WWTP and internal sewer outfalls. Please submit a short response to the

findings in Sections 1 through 4 of this report to EPA and Hawaii DOH, by March 30, 2013.

The main findings are summarized below:

1 The Navy continues to effectively control the generation, delivery, treatment, and

disposal of all domestic and non-domestic wastewaters discharged into the NAVFAC-

HI sewers. Treated discharges are consistently high in quality because of (1) tertiary

treatment and nutrient removal, (2) the 2.5-mile ocean outfall, (3) segregated pre-

treatment of oily wastewaters, (4) segregated pretreatment of process-related

industrial wastewaters, and (5) effective internal controls of non-domestic sources.

2 The resulting 2011-2012 sample record shows consistent compliance with NPDES

permit limits at the WWTP for conventional pollutants, toxics, and nutrients, and

near consistent compliance for whole effluent toxicity. It shows consistent compli-

ance in the quarterly samples for toxics at the internal outfalls, and 5-year geometric

means for nutrients in the receiving waters that were well below Hawaii water quality

standards.

So I retire tomorrow. It is fitting that this report is my last act at EPA for over the

years, there was nothing I enjoyed working on more than Pearl Harbor. And I’ve seen the

remarkable improvements you have made to what now has become by every measure a

state-of-the-art facility operated by exemplary people. I will always fondly remember all of

you, and Pearl Harbor, and the beautiful State of Hawaii, but especially all of you. If you

have any comments or questions, please call Ken Greenberg at (415) 972-3577, or by e-

mail at [email protected].

housing, recreation, facilities, and other support services, including domestic sewer

service, industrial wastewater pretreatment, and sewage treatment at the NAVFAC-HI

WWTP. The Commander of the Navy Region Hawaii provides overall command and

coordination. JBPHH involves a number of other major commands, in particular, PHNSY,

NAVFAC-Hawaii, NAVSUP FLC Pearl Harbor, and the 15th Airlift Wing.

1.1.2 Pearl Harbor Naval Shipyard

The Pearl Harbor Naval Shipyard is a Naval Sea Systems Command (“NAVSEA”) naval

shipyard tenant command located at the JBPHH. PHNSY provides full service fleet

maintenance and repair for naval ships and submarines. The facility consists of four

graving dry docks, and shops and support operations housed in 114 buildings [1].

The on-site shipyard capabilities include ships repair in dry dock, precision and large-

scale machining and metal forming both in shop and on board (CNC lathing, milling,

boring, surface grinding), heat treating, compression and injection molding of plastics

and rubber, engine overhaul and repair, heat exchanger and cooling services cleaning

and repair, air conditioning and refrigeration services, hydraulics services, electrical and

electronics repair, engraving and wire marking, structural metal forming and cutting

(forming, rolling, plasma cutting, laser cutting, water jet cutting, shearing), welding,

sheet metal fabrication, valve and pipe fabrication and repair (acid cleaning, hydro

blasting, cleaning, bending, hydro-testing, flushing), painting and coating (abrasive

blasting, aluminum flame spray, powder and Teflon coating, brush electroplating,

electrostatic epoxy spraying, painting, corrosion control), calibration, shipwright and

wood working, fabric work, insulation, and non-destructive testing [1].

1.1.3 NAVFAC Hawaii Wastewater

NAVFAC-Hawaii operates a JBPHH installation-wide sewer system for the collection and

piped delivery of all domestic and non-domestic wastewaters, including all ships sanitary

(“CHT”) delivered through a dedicated ship wastewater collection ashore abatement

system (“SWWCAAS”), to the NAVFAC-HI WWTP for tertiary wastewater treatment.

Tertiary treated wastewaters discharge through an ocean outfall to the Pacific Ocean.

NAVFAC-Hawaii administratively controls non-domestic wastewater discharges from

numerous sources within the sewer service area through Navy Region Hawaii instruct-

tions 11345.5 for an industrial sewer discharge certification program and 11345.2C for

the applicable internal water quality limits. NAVFAC-Hawaii also operates an oily

wastewater sewer system for the collection and piped delivery of ships bilge to the Bldg

1910 Bilge Oily Waste Treatment System, with the treated wastewaters discharged into

the NAVFAC sewers. NAVFAC-Hawaii collects certain high-strength industrial waste-

waters into tanker trucks for delivery to the Bldg 1424 Industrial Wastewater Treatment

Complex for batch chemical and physical treatment, with the treated industrial

wastewaters discharged into the NAVFAC sewers.

See Sections 1.2 - 1.7 on pages 7 through 14 of this report for detailed descriptions of

the NAVFAC-Hawaii wastewater facilities.


1.1.4 Fleet Logistics Center Pearl Harbor

The NAVSUP Fleet Logistics Center Pearl Harbor provides acquisition, distribution, stor-

age, replacement, and disposition of materiel for the fleet and air force. The FLC Pearl

Harbor capabilities also include HAZMAT management, fuel storage, acquisition, and

refueling, and off-spec fuel reclamation in the Bldg 1403 Fuel Oil Reclamation Facility.

1.2 NAVFAC-Hawaii WWTP

Wastewater Sources, Handling, Treatment, and Discharge

The NAVFAC-HI WWTP, which was formerly known as the Fort Kam WWTP, is a domestic

tertiary wastewater treatment plant with a dry-weather design capacity of 13.0 mgd.

The JBPHH service area has a population of 40,000 and hosts 156 non-domestic sources

internally regulated by the Navy. The WWTP receives domestic sewage, commercial-

related wastewaters from restaurants and stores, and industrial wastewaters generally

from controlled sources. The WWTP also receives ships sanitary, ships bilge water, and

oily wastewaters, specifically associated with ships services, ships repair, and aircraft

services. The NAVFAC-HI WWTP treats on average 5.4 to 5.8 million gallons per day

(“mgd”), with annual peak flows reaching 12-13 mgd, and historical peaks of 30 mgd.

Planned capital improvement projects for 2013 include aeration basin de-lamination

repair, new parshall flume, refurbishment of DAF No.2, DAF sludge line replacement,

replacement of blowers, and the replacement of Pump Station SY01 and its influent line.

Influent and Delivery - Nearly all domestic and non-domestic wastewaters, including

ships sanitary, arrive by trunk lines from Pump Station SY01 Pearl Harbor and Pump

Station 1A/1B Hickam. Wastewaters arrive weak in strength with the influent BODs

averaging only 70-85 mg/l. NAVFAC also collects food-related grease and miscellaneous

wastes (not septage) from Navy sources for delivery by tanker truck into an on-site

dump station which consists of two 15,000 gallon storage tanks and hard-plumbed lines

to anaerobic Digester No.1. See Photo #1 in Section 1.10 on page 15 of this report.

Treatment Capability - Treatment involves headworks barscreening, primary sedimenta-

tion, activated sludge aeration/nitrification and anoxic-zone denitrification, secondary

clarification, traveling-bridge sand filtration, ultraviolet disinfection, and a 2.5-mile deep-

water ocean outfall. The activated sludge consists of four anoxic basins followed by six

aerobic basins, which together operate at a mean cell residence time θc of ~18 days.

Operations typically involve all four anoxic basins and three of the six aeration basins.

Because of weak influent strength, the WWTP does not achieve removal rates of at least

85% for conventional pollutants. Solids handling involves hydrocyclone de-gritting,

polymer-aided dissolved air flotation thickening, anaerobic digestion, and centrifuge

dewatering. The anaerobic digestion occurs in three fixed-dome digesters, two operated

in the mesophyllic range (95°F), and one in the thermophyllic range (125°F), with the

overall digestion mean cell residence time θc of ~60 days. See Photos #2 through #12

in Section 1.10 on pages 15 through 17 of this report.

Residuals - Headworks screenings and the hydrocyclone removed grit are delivered to a

Hawaii Power waste-to-energy project. Centrifuge dewatering produces digested sludge

with a solids content of roughly 13%. NAVFAC delivers the centrifuged digested sludge

to a bioremediation farm at Barbers Point for composting.

Odor Control – The NAVFAC-HI WWTP employs three sets of bio-towers for biological

odor reduction and sulfide destruction at (1) the headworks, (2) the sludge centrifuge,

and (3) Pump Station SY01. Each bio-tower set consists of stackable enclosed pallets

with wood, clay, ceramic gravel, and fertilizer, through which collected fumes are drawn.

See Photos #13 through #15 in Section 1.10 on page 17 of this report.

NPDES Sample Points - The NPDES permit requires influent sampling just upstream of

the headworks and effluent sampling after UV disinfection. Sludge samples are of

dewatered digester sludge. For the purposes of this inspection report, the sample points

are designated in this report as NPDES-001Inf, NPDES-001Eff, and NPDES-001Sldg,

respectively.


1.3 COMNAVREG Hawaii Instructions

Internal Regulation of Non-Domestic Discharges

In 1989 the Commander of the Navy Region Hawaii issued COMNAVREG Instructions

11345.5 and 11345.2C establishing a sewer discharge permit system and wastewater

discharge limitations for industrial wastewaters into the JBPHH sewer service area.

Under the authority of the COMNAVREG Instructions NAVFAC issues wastewater dis-

charge certificates to each non-domestic source establishing the specific terms allowing

discharge of non-domestic wastewater into the domestic sewers. See Photo #16 in

Section 1.10 on page 17 of this report.

According the 2011 NAVFAC pretreatment annual report, the JBPHH service area hosts

156 certificate non-domestic sources. Sixteen of these sources are categorical or con-

sidered significant, 8 are cooling towers, 41 are other industrial-related sources such as

test stands, laboratories, and washing sinks, and 91 are commercial-related sources

such as restaurants, swimming pools, vehicle maintenance shops, and dental offices.

The 2011 NPDES permit for the NAVFAC-HI WWTP requires the Navy to implement the

COMNAVREG Instructions. In particular, Part E(2)(a)(6) requires NAVFAC to prohibit

non-domestic discharges into the sewers in concentrations exceeding the COMNAVREG

Instruction. Part E(2)(b)(1) prohibits any source from discharging non-domestic

wastewaters into the sewers without first obtaining an industrial wastewater discharge

certificate from NAVFAC.


1.4 Bldg 1424 Industrial Wastewater Treatment Complex


NAVFAC handles industrial wastewaters generated by Pearl Harbor sources in the Bldg

1424 Industrial Wastewater Treatment Complex (IWTC). The IWTC has the capability to

accept for batch treatment as much as 34,000 gallons of cost-efficiently treatable but

not strictly oil-bearing industrial wastewaters and can impound another 40,000 gallons

for treatment later. Untreatable or costly-to-treat industrial wastewaters are handled

through hazardous waste collection for off-site disposal. Oily wastewaters are handled

through the Bldg 1910 BOWTS.

Influent and Delivery – All wastewaters arrive at the Bldg 1424 IWTC by tanker truck or

by trucked delivery of drums to two receiving bays. Most wastewaters are collected

from the ships in repair, including, according to IWTC logs, hydroblast tail water, acid

wash waters, citrate rinse water, contaminated bilge, steam clean tail water, wash rack

waste-water, waste chemicals, CHT chlorinated disinfection grey water, chelate

wastewater, dock water with paint chips, and equipment hydrotesting water. The

remainder consists of deliveries from the hose and pipe shop, brush plating, corrosion

control, the firefighting school, and hazardous waste collection sites. See Photo #17 in


Treatment Capability – The Bldg 1424 IWTC provides batch metals removals, solids

removal, oil removal, and organics destruction. It consists of five 5,000 gallon batch

reactor tanks, a sixth 5,000 gallon holding tank feeding an oil/water separator, two

2,000 gallon brine holding tanks, four 10,000 gallon stand-by holding tanks, a fifth

10,000 gallon holding tank feeding reactor tank decant through a final sand filter for

discharge to the NAVFAC-HI sewers, and residuals handling equipment. Reactor Tanks

#5, #6, #7, and #8 each can provide metals hydroxide precipitation, ferrous sulfate

coagulation, EDTA chelation, polymer flocculation, chemical oxidation and reduction, and

settling, depending on the wastewater characteristics. The batch reactor Tank #30 can

provide UV/peroxide oxidation of organic-laden wastewaters such as aqueous firefighting

foam. The batch holding Tank #4 and following oil/water separator provides oil removal

in conjunction with the removal of inorganics. Holding Tanks #17 and #18 feed through

a reverse osmosis and ultrafiltration system. Each reactor tank is outfitted with pH and

ORP metering to measure reaction end-points. NAVFAC conducts jar tests of incoming

deliveries to determine the necessary reactions and reaction end points. See Photos

#18 through #23 in Section 1.10 on pages 17 and 18 of this report.

Residuals - Reactor tank residuals are transferred to two 2,000 gallon sludge holding

tanks, Tank #11 for inorganic sludges, and Tank #12 for oily sludges. The sludges are

then fed through two diatomaceous earth-coated filter presses followed by a low-tem-

perature/ low-pressure evaporator. Press filtrate returns to the receiving bays. NAVFAC

hauls filter press cake off-site as non-hazardous. Removed free oils fill another holding

Tank #10 for off-hauling to the Bldg 1403 Fuel Oil Reclamation Center. See Photo #24

in Section 1.10 on page 18 of this report.

Certificate Sample Point – A NAVFAC Certificate establishes a compliance sample point

for the Bldg 1424 IWTC discharges to the NAVFAC-HI domestic sewers. This certificate

sample point is after final sand filtration. This certificate sample point is designated in

this report by certificate number as IWD-1622 and as NPDES-014i. See Photo #23 in


1.5 Bldg 1910 Bilge Oily Wastewater Treatment System


NAVFAC handles the oily wastewaters generated by Pearl Harbor sources including ships

bilge, ships ballast, and fuel reclamation tail waters in the Bldg 1910 Bilge Oily Waste-

water Treatment System (BOWTS). The Bldg 1910 BOWTS accepts 8 million gallons

per year (20,000 gpd) of oily wastewater. The peak design capacity is 420,000 gpd.

Influent and Delivery – Oily wastewaters arrive at the Bldg 1910 BOWTS either by dedi-

cated bilge sewer line, tanker truck, or by barge to a bilge sewer line connection. Naval


station sources connect ships bilge into pierside risers under the control of NAVFAC-HI.

The pierside risers connect at the Bravo piers to Pump Stations #7 and #8 and at the

submarine piers to Pump Stations #3, #4, and #5 for delivery to the Bldg 1910 BOWTS

by dedicated pipeline. Port operations arrange the delivery time with NAVFAC and

certify the wastewater type and flow for delivery to the BOWTS. Ships ballast, collected

into ships waste off-load barges (“SWOBs”), is also pumped into the pierside risers for

delivery to the BOWTS. PHNSY sources deliver oily wastewater by tanker truck [4].

Treatment Capability – The Bldg 1910 BOWTS consists of equalization and two parallel

treatment units. Equalization involves a 1.6 million gallon oil storage tank internally

partitioned into thirds. The compartments fill one at a time in sequence with floating oils

skimmed to an unused compartment. Once per year, skimmed oils are delivered by

tanker truck to the Bldg 1403 Fuel Oil Reclamation Center. Decant then proceeds

through two 150 gpm capacity chemical treatment units. Chemical treatment units A

and B are identical in configuration, providing oil water separation, peroxide oxidation of

sulfides, caustic and polymer-aided flocculation, and induced air flotation removal of

coalesced oil. See Photos #25 to #28 in Section 1.10 on page 19 of this report.

Residuals – Chemical floc froth from the induced air flotation units is dewatered through

sludge decant holding and a filter press with the press slurry hauled off-site as hazar-

dous by DLA Disposition Services. NAVFAC has also installed pilot project bioreactors to

determine whether oily sludges can be batch treated. Each pilot project bioreactor has a

prospective design capacity to treat 500 gallons of sludge every 12 days. See Photos

#29 and #30 in Section 1.10 on page 19 of this report.

Certificate Sample Points – A NAVFAC Certificate establishes two compliance sample

points for the Bldg 1910 BOWTS discharges to the NAVFAC-HI domestic sewers. These

certificate sample points are sited at the ends of chemical treatment units A and B.

These certificate sample points are designated in this report by certificate number as

IWD-1623a and IWD-1623b. See Photo #28 in Section 1.10 on page 19 of this report.

1.6 Bldg 1403 Fuel Oil Reclamation Center


NAVSUP FLC Pearl Harbor processes for reclaim accumulated petroleum products (not

used oil) from ships, shipyard shops, accumulation pits, tank bottoms from the Red Hill

and Upper Tank Farm, and Hotel pier sump drainage in the Bldg 1403 Fuel Oil Reclama-

tion Center (“FORC”). The Bldg 1403 FORC does not operate as designed.

Influent and Delivery – Accumulated petroleum products arrive by vacuum truck for

delivery into Bldg 1403 FORC reclaim pit. Sump drainage from the Hotel pier also is

pumped to Tank B-1. FLC Pearl Harbor tests each delivery with clean fuels recovered as

fuel stock, and contaminated or water-logged petroleum drained to the reclaim pit.

Treatment Capability – The Bldg 1910 FORC consists of a reclaim pit and two 400,000

gallon tanks for skimming and product storage. Decanted tail waters from Tank B-1

drain through caustic and polymer-aided oil water separation, dissolved air flotation, and

final cartridge filters. FLC Pearl Harbor treats the decant in 26,000 gallon batches equi-

valent in volume to the DAF tank, with the chelated float and the treated water-fraction

subnatant fed through cartridge filters. The DAF unit is not operated as designed since

there is no DAF float removal, but rather a reliance on final filtration to remove solids.

The DAF also would operate more efficiently with metered continuous feed from settling

Tank B-1. See Photos #31 and #34 in Section 1.10 on page 20 of this report.

1.7 Ship-to-Shore Collection of CHT Ships Sanitary

NAVFAC provides the pierside services to berthed ships of potable water, collecting/

holding/transfer (“CHT”) ships sanitary wastewater disposal, (3) bilge water disposal,

and (4) salt water firefighting water. Each of these services stub-out at intervals along

the piers for connection by hose to the ships. The size and color of the fittings for each

of the four services are different, blue for potable, gold for ships sanitary, yellow and

black for bilge, and red for fire. CHT ships sanitary sewer is delivered through numerous

lift stations to the NAVFAC-HI domestic sewer system. The ships contact NAVFAC Ships

Services for CHT ships sanitary sewer [5]. NAVFAC does not issue certificates for

discharge. See Photos #35 and #36 in Section 1.10 on page 20 of this report.

1.8 Facility SIC Code

Joint Base Pearl Harbor Hickam is assigned the SIC code for national security (SIC

9711). NAVFAC-HI WWTP is assigned the SIC code for sewage treatment (SIC 9525).

2.0 NPDES Permit Requirements

The NPDES permit must apply Federal BAT/NSPS standards to all regulated sources and

the Hawaii water quality standards to the discharge to the ocean.

Summary

The NPDES permit for the NAVFAC-HI Wastewater Treatment Plant currently in effect

was issued on September 7, 2011, took effect on October 7, 2011, and is set to expire

on September 6, 2012. The permit imposes (1) Federal BAT/NSPS standards for secon-

dary wastewater treatment, (2) limits implementing the Hawaii water quality standards

for the outfall, zone of initial dilution, and zone of mixing, and (3) internal limits as the

expression of BAT for metal finishing and other non-domestic sources discharged into

the NAVFAC-HI sewers. The application of standards and limits was determined through

visual inspection. See Appendix 1 on page 29 of this report for NPDES permit limits.

Requirements

None.

Recommendations

None.

2.1 Federal BAT/NSPS Categorical Standards

Part A(1)(a) of the 2011 NPDES permit incorporates Federal standards for secondary

treatment of domestic sewage. The permit establishes concentration-based and mass-

based limits for BOD and TSS for both 30-day and 7-day averages, as well as

instantaneous limits for pH. The mass-based limits are based on the average dry

weather treatment plant capacity of 13.0 mgd. The permit, in accordance with 40 CFR

133.103(d), also continues to waive the secondary treatment standards to attain 85%

removal rates for BOD and TSS because of the weak strength of the influent.

2.2 Water Quality Based Effluent Limits

The NPDES permit applies Hawaii water quality standards to the discharges from the

NAVFAC-HI WWTP through the ocean outfall. The permit applies the water quality-

based limits (1) to the plant effluent discharges into the outfall, designated in this report

as NPDES-001, (2) to the Zone of Initial Dilution (“ZID”) boundary over and around the

outfall diffuser, and (3) to a designated by permit Zone of Mixing (“ZOM”) boundary for

the assimilation of the tertiary treated wastewaters.

Effluent Outfall – Part A(1)(a) of the 2011 NPDES permit applies the water quality stan-

dards for settleable solids, oil and grease, and enterococci without adjustment to the


NAVFAC-HI WWTP effluent at NPDES-001. In addition, Part A(1)(a) of the permit also

applies a ZID critical dilution factor to the water quality standards for a number of toxic

parameters to arrive at additional end-of-pipe water quality-based effluent limits

(“WQBELs”) for the treatment plant effluent discharge at NPDES-001. The resulting

end-of-pipe WQBELs include limits for total nitrogen, ammonia, total phosphorus, total

residual chlorine, and chronic whole effluent toxicity, and result in no limits but

continued self-monitoring for certain toxics (copper, lead, mercury, selenium, silver,

cyanide, 4,4-DDD, dieldrin, tributyltin, dioxin, PAHs, PCBs, and other toxic organics).

Zone of Initial Dilution – The ZID is the area of the plume around and above the diffuser

where density differences cause the effluent to rise and disperse. The permit fact sheet

lists the critical initial dilution factor as 111:1. Calculations of critical initial dilution

factors depend on a number of fixed constants, in particular, the outfall diffuser depth,

diffuser length, the number of diffuser ports, density differences, and the receiving

water currents, as well as on the independent variable of the expected peak outfall

discharge flow rates. Part C(1) of the permit defines the resulting spatial dimensions of

the ZID. Part C(2) of the 2011 NPDES permit advances statistically-derived limits that

apply at the boundaries of the ZID for total nitrogen, ammonia, total phosphorus,

chlorophyll-a, turbidity, dissolved oxygen, change-in-pH, change-in-temperature, and

change-in-salinity. The statistically-derived limits comprise the geometric mean, the

90th-percentile event, and the 98th-percentile event.

Zone of Mixing – The ZOM is a geographic area in the receiving waters with the capacity

to assimilate pollutants without exceeding the water quality standards at the boundaries.

Parts C(1) and C(4) of the 2011 NPDES permit establishes the spatial dimensions of a

ZOM around the outfall. Part C(3) of the permit advances geometric mean, 90th-per-

centile, and 98th-percentile statistical limits for nitrate+nitrite at the ZOM boundaries.

2.3 Internal Federal BAT/NSPS Standards for Non-Domestic Wastewaters

Parts A(1)(c), A(1)(d), and A(1)(e) of the 2011 NPDES permit apply the Federal metal

finishing standards in 40 CFR 433 to defined internal wastewater discharges into the

NAVFAC-HI sewers from qualifying wastewater sources. In order to maintain BAT for

the entire sewer service area, Part E of the permit also requires implementation of an

Industrial Wastewater Sewer Discharge Permit System for non-domestic wastewater

sources that functions in a similar manner to the NPDES pretreatment requirements for

Publicly-Owned Treatment Works (“POTWs”). The NAVFAC-HI sewer system would not

qualify as a POTW under the definitions in 40 CFR 403.

2.3.1 Metal Finishing Sources

Facility Definition - The JBPHH military installations perform ships repair and aircraft

maintenance functions in a number of installations that, because they are contiguous,

are considered as one facility. The definition of "facility" comes from the Federal Clean

Water Act regulations which define a "source" as not just a building under one com-

mand, but as a building, structure, facility, or installation from which there is or may be


a discharge of pollutants, 40 CFR 122.2. The metal finishing regulations further refer to

the regulated entity as a plant, user, industrial facility, or source, 40 CFR 433.10(a) and

433.14. Taken together a "facility" is defined by common function (ships repair and

aircraft maintenance) on a contiguous piece of property. The JBPHH military installa-

tions, defined as one facility for purposes of the Clean Water Act, does not extend to the

ships berthed in port, or to other non-contiguous military installations.

Standards - The BAT/BPT standards for existing source metal finishing advance limits for

metals, cyanide, toxic organics, oil & grease, suspended solids, and pH, for discharges to

waters of the United States. The 2011 NPDES permit applies these standards to the

internal outfalls for metals, cyanide, and toxic organics, leaving out the standards for oil

& grease, pH, and suspended solids. This is appropriate because the internal waste-

water discharges are further treated by NAVFAC-HI WWTP for suspended solids, oil and

grease, and regulated for pH. Parts A(1)(c) and A(1)(d) apply the BAT/BPT standards

for new and existing source metal finishing from 40 CFR 433.14 and 40 CFR 433.16 to

defined internal outfalls. See Table 1.3 on page 9 of this report for the list of internal

outfalls under regulation as metal finishing sources. The 2011 NPDES permit lists other

sources which would be under regulation if their outfalls discharged to the sewers.

Applicability - Under 40 CFR 433.10(a), the metal finishing standards "... apply to plants

that perform ..." the core operations of electroplating, electroless plating, etching,

anodizing, chemical coating, or printed circuit board manufacturing and they extend to

other on-site operations, such as cleaning, machining, grinding, sand blasting, welding,

soldering, solvent degreasing, painting, paint stripping, assembly, calibration, and

testing, associated with metal finishing and specifically listed in 40 CFR 433.10(a). If

any of the core operations are performed, the metal finishing standards apply to dis-

charges from any of the core or associated operations. As a result, since the Navy

performs copper and nickel plating in Bldg 67, alodining in Bldg 67 (a form of chemical

coating), deoxidation, acid etching, and desmut in Bldg 67, and acid cleaning in Bldg

1456 once upgraded, and acid cleaning and deoxidation dockside at the graving docks

(all forms of chemical etching), the metal finishing standards apply to the discharges

listed in Table 1.3 on page 9 of this report.

Centralized Treatment Applicability - The Bldg 1424 IWTC receives wastewaters from

existing source metal finishing operations, new source metal finishing, and sources that

are considered unregulated under the Federal standards. As a result, the Federal

standards for the Bldg 1424 IWTC falls between the standards for existing and new

source metal finishing for cadmium but are otherwise unadjusted because no dilution

waters are involved. Federal standards applied to combined waste streams are adjusted

using the combined waste stream formula:

Ctotal = (C433exist Q433exist) + (C433new Q433new) x Qtotal - Qdilution C – concentration

(Q433exist + Q433new) Qtotal Q – flow

The Bldg 1910 BOWTS and Bldg 1403 FORC receive only unregulated waste streams and

thus do not discharge wastewaters into the NAVFAC-HI sewers that qualify for regulation

under the Federal metal finishing standards.


Basis of the Standards - The metal finishing standards were based on a model pretreat-

ment unit that comprises metals precipitation, settling, sludge removal, source control of

toxic organics, closed-loop zero discharge of cadmium, and if necessary, chromium

reduction and cyanide destruction. The best-available-technology standards were set

where metal finishers with model treatment operated at a long-term average and

variability that achieved a compliance rate of 99% (1 in 100 chance of violation).

Adjustments – The Bldg 1424 IWTC receives combined waste streams from regulated

and unregulated sources. Otherwise, no adjustments are necessary to account for

multiple Federal categories or unregulated flows. Under 40 CFR 433.12(c), the cyanide

standards default without adjustment when there are no cyanide bearing flows.

2.3.2 Non-Domestic Certificate Discharges

Parts E(1-3) of the 2011 NPDES permit require implementation of the discharge limits in

COMNAVREG Hawaii Instruction 11345.2D established to protect the sewers, treatment

plant, and receiving waters from adverse impacts. The Instructions prohibit discharges

that can cause the pass-through of pollutants into the receiving waters, the operational

interference of the treatment works, contamination of the sewage sludge, sewer worker

health and safety risks, fire or explosive risks, and corrosive damage to the sewers.

3.0 Compliance with NPDES Permit Requirements

Treated wastewater discharges from the NAFVAC-HI WWTP must comply with the NPDES

permit limits for Federal secondary treatment and the Hawaii water quality standards at

the outfall, at the boundary of the zone of initial dilution, and at the boundary of the

zone of mixing. [NPDES Permit §A(1)(a), §A(1)(b), §C(3)]

Non-domestic discharges to the sewers from categorical sources must comply with the

NPDES permit limits for Federal categorical standards at the internal outfalls. [NPDES

Permit §A(1)(b)]

Non-domestic discharges to the sewers from categorical and non-categorical sources

must comply with internal limits enacted through Navy instruction in accordance with a

NAVFAC certificate discharge program. [NPDES Permit §E]

Summary

NAVFAC provides best-available-technology treatment for all of the domestic and non-

domestic wastewaters discharged into the NAVFAC-HI sewers by JBPHH, PHNSY, FLC,

berthed ships, aircraft, and tenant commands. As a result, NAVFAC has succeeded in

achieving consistent compliance with nearly all of the discharge requirements in the

2011 NPDES permit, both the technology-based requirements for conventional pollutants

and toxics, and the water quality-based requirements for toxics and nutrients. The

design and configuration of the BAT-equivalent treatment on-site involves (1) tertiary

treatment for conventional pollutants and nutrients of all domestic and non-domestic

wastewaters collected into the NAVFAC sewers, (2) a 2.5-mile long ocean outfall, (3) oil

wastewater treatment for ships bilge, ships ballast, recovered fuels, tank farm bottoms,

and other oily wastewater sources, (4) industrial wastewater batch treatment for the

process-related wastewaters generated by berthed ships, shops, dry dock repair work,

and aircraft maintenance, and (5) internal controls of other non-domestic sources into

the sewers under a base instruction certificate discharge program.

This inspection documents that all aspects of the treatment and control of wastewaters

discharged into the NAVFAC-HI sewers were found to be fully and effectively functioning,

with one minor exception (Bldg 1403). As a result, the sample record from January

2011 through September 2012 indicates consistent compliance at the WWTP outfall in

over 600 daily samples with the permit-limited requirements for conventional pollutants,

toxics, and nutrients, and near consistent compliance in 23 tests for chronic whole

effluent toxicity. Subsequent toxicity testing returned to consistent compliance. See

Appendix 2 on page 30 of this report for a summary of the WWTP sampling record.

The 2011-2012 sample record also shows consistent compliance in the 63 quarterly

samples for toxics collected from the 15 NPDES permit-regulated internal outfalls, with

only a single violation of a single parameter in one internal discharge of only 12 gallons.

Subsequent discharges from this internal outfall were suspended. The 2010 and 2011

industrial pretreatment annual reports required by the NPDES permit also indicate that

internal sources of non-domestic wastewaters are internally inspected, monitored, and


evaluated by NAVFAC for certificate discharge. See Appendix 3 on pages 31-35 of this

report for summaries of the sampling records for the internal outfalls.

The September 2012 DMR also reports the 5-year (May 2007 to August 2012) 12-

sample geometric mean for the various ZID and ZOM boundary sample points. All

calculated geometric means for the receiving water samples were significantly below the

Hawaii water quality standards for total nitrogen, ammonia, nitrate+nitrite, total

phosphorus, chlorophyll-a, and turbidity. See Appendix 4 on page 36 of this report for

the September 2012 geometric means.

Requirements

None.

Recommendations

FLC should consider (1) operating the Bldg 1403 DAF unit to remove float, and (2)

metering accumulated oily wastewater through the DAF at a consistent feed rate.


4.0 Compliance with NPDES Permit Monitoring Requirements

The influent and effluent discharges from the NAVFAC-HI WWTP at NPDES-001Eff and

NPDES-001Inf, must be self-monitored for discharge flow rate, nutrients, conventional

pollutants, toxics, residual chlorine, pH, and whole effluent toxicity. [NPDES Permit

§A(1)]

The receiving waters at the boundaries of the ZID and/or ZOM must be self-monitored

for nutrients, turbidity, and chlorophyll-a. [NPDES Permit §C]

The internal outfalls into the NAVFAC-HI sewers designated as NPDES-002i through

NPDES-026i must be self-monitored for flow rate, metals, cyanide, and toxic organics.

[NPDES Permit §A(1)].

Summary

Data Review Scope – The data review involved the DMRs submitted by NAVFAC covering

the NPDES effluent discharge point and internal outfalls, for all permit required para-

meters, from January 2011 through September 2012. This data review also involved

the calculated geometric mean for the ZID and ZOM boundaries, for nutrients, turbidity,

and chlorophyll-a, from May 2007 through August 2012. See Appendix 1 on page 28 for

the NPDES permit requirements. See Appendices 2, 3, and 4 on pages 30, 31, and 36

for the NPDES permit self-monitoring results.

Permit Requirements – For the sample record reviewed in this inspection, NAVFAC has

successfully fulfilled the NPDES permit self-monitoring requirements. The DMRs show

that NAVFAC has done the following: (1) submitted sample results for all permit listed

parameters at the frequencies set forth in the permit for NPDES-001Eff, NPDES-001Inf,

for the ZID and ZOM designated sample locations, and for the internal outfalls, NPDES-

002i through NPDES-026i; (2) collected all samples from the compliance sampling

points; (3) correctly obtained composites or grabs, and; (4) analyzed at detection limits

below the NDPES permit limits. It was not determined whether appropriate chain-of-

custody procedures were followed.

Requirements

None.

Recommendations

None.
