RE: ClassIIAirQualityRenewalPermitNo.55223ComprehensiveRequestforAdditionalInformation,RevisedAirDispersionModelingReport
DearBalaji:
InJuly2017,theRosemontCopperCompanysubmittedaClassIISyntheticminorpermitrenewalapplicationtotheArizonaDepartmentofEnvironmentalQuality.Therenewalapplicationincludedanairqualitymodelingreport(ProjectReport,RosemontCopperCompany,PimaCounty,AZ.AERMODModelingReport.July2017)documentingthemethodologyandresultsoftheairqualityanalysespreparedinsupportofAirQualityClassIISyntheticMinorPermit(Permit#55223)renewalandmodificationfortheRosemontCopper(Rosemont)Project.
BasedonADEQ’spreliminaryreviewofthemodelingreport,onSeptember26,2017theagencyprovidedaComprehensiveRequestforAdditionalInformation(hereinafterreferredtoasComprehensiveRequest).OnNovember17,2017,RosemontrespondedtotherequestandprovidedanAmendedAERMODModelingReport,aswellasacoverletterdetailingtheitemsincludedintheComprehensiveRequestalongwithRosemont’sresponsetothoseitems.OnDecember7,2017,aconferencecallwasheldbetweenADEQ,Rosemont,andTrinityConsultants(Trinity),duringwhichADEQrequestedadditionalmodificationstotheAERMODModelingReportandassociatedemissionsinventory.Theadditionalmodificationsincludethefollowingitems.Foreachitem,Rosemont’sresponseorassociatedmodelrevisionhasbeenidentifiedinboldtext

2. On‐siteMeteorologicalMonitorBaseElevation
Thebaseelevationfortheon‐sitemonitorgivenintheAERMETfilesis1591meters;however,thebaseelevationusedintheAERMODfilesis1567meters.Rosemontshoulddeterminewhichelevationiscorrect,andusethatelevationinboththeAERMETandAERMODfiles.
Itwasdeterminedthatthecorrectbaseelevationofthemonitoris1591meters.Themodelinganalysishasbeenrevisedtouseanelevationof1591metersinboththeAERMETandAERMODfiles.
3. DryStackTailingsVolumeSources
ItwasunclearfromthedescriptionprovidedintheAERMODModelingreporthowthedimensionsofthevolumesourcesrepresentingthedrystacktailingsweredetermines.ADEQrequestedRosemontrevisethemodeleddimensionsofthethreevolumesourcesthatarebeingusedtorepresentthedrystacktailingsanddescribethemethodologyinthemodelingreport.
Thevolumesourcesrepresentingthedrystacktailingswerepreviouslychosenbasedontotaltailingsareasize,withemissionsassignedbasedonvolumesourcesize.Thevolumesourceshavebeenrevisedtomoreaccuratelyrepresentthedisturbedtailingsarea(500acres)usingthreeequallysizedvolumesourcesandemissionsdistribution.TherevisedmethodologyisdetailedinSection6.8.2.2oftheDecember2017AmendedAERMODModelingReport.
4. CombinationHaulRoadLengthandSourceAllocation
Thetotallengthofthecombinationhaulroadsusedintheemissionscalculationsandsourceallocationdidnotcorrespondtothelengthofthecombinationhaulroadrepresentedinthemodel.ADEQrequestedRosemontrevisethenumberofvolumesourcesfortheoutofpitcombinationhaulroadinthemodeltoensureitisconsistentwiththeemissionsinventory.
Thehaulroadlengthrepresentedinthemodelinadvertentlyincludedaportionoftheinpitcombinationhaulroad.Thenumberofvolumesourcesfortheoutofpitcombinationhaulroadhasbeenrevisedinthemodel(previously93volumesources,now31volumesources)andtheemissionssourceallocationwasrevised.
5. HaulRoadDimensions
ADEQrequestedthatRosemontcalculatetheinitialverticaldimensionofthehaulroadvolumesourcesusing1.7timesthetruckheightandcalculatetheinitialhorizontaldimensionofthehaulroadsusingthetruckwidthplus6meters.
ThehaulroaddimensionshavebeenupdatedperADEQ’srequest.TherevisedmethodologyanddimensionsaredescribedinSection6.8.2.1oftheDecember2017AmendedAERMODModelingReport.

Rosemont Modeling Protocol
BACKGROUND INFORMATION Ambient monitoring at the Rosemont Project for PM10 concentrations has been performed and
recorded from June 16, 2006 to June 30, 2009. Within this data, there are several concentration
measurements that appear to be outlying data and cannot be explained by any reasonable statistical
distribution. This document analyzes the outlying data points to determine the probability of their
occurrence to determine whether they are reasonable recurring events.
ANALYSIS The PM10 concentration measurements as a function of the date they were recorded are presented in Figure B.1. The possible outlying data points are the concentrations 71.3 and 40.3.
Figure B.1: PM10 Concentration Measurements
In order to statistically analyze the PM10 concentrations, the type of data distribution needs to be
determined. The simplest distribution is called a normal distribution. To test for normal distribution,
the standard normal concentrations (Z) are plotted against the measured PM10 concentrations. If a
linear regression line fits the plotted data points reasonably, a normal distribution can be assumed. The standard normal concentrations are calculated by Equation 1:
X - Z (1)

The normal and standard normal probability density functions for the PM10 concentration
measurements are shown in Figures B.3 and B.4. Both of these figures represent the same function.
The only difference is that Figure 4 is plotted with the standard normal data (Z). This implies that the
mean of the standard normal data is 0 and variance (standard deviation squared) is equal to 1. The
standard normal data and standard normal probability density function will be used in further analysis.

Figure B.4: Standard Normal Probability Density Function The probability density function (f(x)) also produces the probability of an event occurring in a future
sample. For the PM10 concentration data, this means the probability of the PM10 concentration
occurring during a future measurement. The possible outlier data points and their probability to occur
during a random measurement are shown in Table B.1.
The probability of a future measurement being equal to or exceeding the measured data point is also
shown in Table C.1. This value is calculated using Cumulative Standard Normal Distribution tables.
Based on the standard normal value of a data point, the Cumulative Standard Normal Distribution
tables produce the probability that a future measurement will be less than or equal to the data point.
Since the standard normal probability function is symmetric (centered at a mean of 0), the probability
of the measurement being greater than the data point can be calculated by Equation 3:
PZ z1- PZ z (3)

P = Probability
Z = Future data

10/27/08 31.6 2.16 4.21E-03 0.98 0.02
CONCLUSION
The probabilities in Table B.1 show that it is highly unlikely that a PM10 concentration measurement greater than 71.3 or 40.3 μg/m3 will occur in future measurements (0.00000000587% and 0.0981%,
respectively). If the probability equals 5.87E-11, then of the next 100 billion samples taken, the outlier
(or greater values) is expected to occur 5.87 times. Similarly, of the next 10 billion samples taken, it is
not even expected to occur (since it is expected to occur 0.587 times, which is less than 1). A
concentration measurement of 31.6 μg/m3 has a 2% probability of occurring and therefore, the data
point should not be considered an outlier during further PM10 concentration data analysis.

Re: Response to the Forest Service April 22, 2010 Request for Clarifications
Dear Ms. Arnold:
Presented below please find a citation of the Forest Service Request for Clarification and the corresponding response.
Section 7.1.2: Please provide documentation supporting the NO2/NOx ratios used in the NO2 analysis of the various types of equipment proposed to be used. This information is necessary for us to evaluate the four scenarios offered for NO2 modeling and select the best option.
Documentation and Clarifications:
The one-hour NO2 standard was published in the Federal Register on February 9, 2010 (75 FR 6474-6537), becoming effective April 12, 2010. Following its promulgation, EPA issued memoranda on June 29, 2010 and March 1, 2011 clarifying the applicability of current guidance in the Guideline on Air Quality Models for modeling NO2 impacts. The two memoranda reflect major uncertainties regarding appropriate in-stack NO2/NOx ratios for use by the current AERMOD Model.
Except for emergency generators that operate only during emergency conditions when there is a disruption to mining processes, sources of NOx emissions are comprised of blasting (884 lb/hr), a small boiler (0.876 lb/hr) and mobile sources (315.25 lb/hr). Emergency generators were not included in the modeling analyses because they would not operate when mining operations would be taking place, and are also excluded from consideration by the March 1, 2011 EPA memorandum. The NO2/NOx ratio due to blasting emissions is uncertain, however blasting is constrained to occur only between the hours of 12:00 (noon) and 4:00 P.M (i.e. starting at noon and ending at 5:00 P.M.). The maximum predicted 1-hour NOx impacts due to blasting for any single hour for the three meteorological years that were modeled during these hours is 8.58 μg/m3, or 4.5% of the 1-hour NO2 standard. Because not all NOx emissions will be in the form of NO2, the actual NO2
impact will be lower. Consequently, the overwhelming sources of NOx emissions that can contribute to significant NO2 impacts are mobile sources.
Data of in-stack NO2/NOx ratios for mobile sources (i.e. internal combustion engines) is very limited, if not unavailable. In order to address the information requested by the Forest Service, requests were made to Caterpillar Inc, the major supplier of mobile equipment to Rosemont, and to Leonard Montenegro, former Supervisor of the Air Quality Evaluation Group at the Arizona Department of Environmental Quality, to research and provide such information.

![Page 59: portal.azoah.com · VIA E‐MAIL: Vaidyanathan.Balaji@azdeq.gov December 15, 2017 Mr.Balaji Vaidyanathan Manager, Facilities Emission Control Section Arizona Department of Environmental](https://reader036.fdocuments.net/reader036/viewer/2022071000/5fbc1773013e5f21f87885eb/html5/thumbnails/59.jpg)
Page 2 of 4 A letter from Caterpillar Inc. is attached citing “engine out” NO2 as being 5 to 15% of NOx emissions for engines without an oxidation catalyst or catalyzed DPF. Mobile sources at the Rosemont facility will not be equipped with oxidation catalysts or catalyzed DPF. As indicated below, the NO2/NOx ratio of “engine out” emissions overestimates the in-stack ratio because such measurements have been made after the engine exhaust has been mixed with ambient air and the NO to NO2 conversion has already commenced. In-stack NO2/NOx ratios should thus be less than those cited by Caterpillar Inc.
The research conducted by Mr. Montenegro is attached. The research describes the techniques used to measure emissions from the exhaust of IC engines, the results of measurements designed to determine in- stack NO2/NOx ratios (2-6%), and ratios used by EPA to evaluate the sensitivity of AERMOD’s algorithms for modeling NO to NO2 conversion and exposure assessment studies (5-10%). Mr. Montenegro’s research supports an in-stack NO2/NOx ratio of somewhere around 5%.
Independent of the representativeness of the NO2/NOx ratio used to evaluate potential 1-hour NO2
concentrations, all parties to the EIS should also consider the conservativeness of the modeling. As indicated during past conference calls with the Forest Service and National Park Service, short term standards were evaluated by assuming maximum hourly emissions, i.e. all equipment (except emergency generators) are operating concurrently at all time, i.e. 8760 hours/year. This cannot occur. Haul trucks, for example, have a design annual operating hour capacity of 6600 hours and not 8760 hours. Emissions from haul trucks represent 260.8 lb/hr of the 315.25 lb/hour that were modeled for mobile sources. Use of 6600 hours would reduce hourly emissions from all mobile sources to 250.95 lb/hour, or a 20% decrease in total mobile source emissions. Other equipment will also not be operating on a continuous basis.
Other assumptions that increase the conservativeness of the modeling even further include the following:
The assumption that the highest background NO2 concentration occurs every hour of the year. A
more typical background concentration that would be anticipated to occur would be the average concentration. The highest hourly and average NO2 concentrations at the Alamo background site are 24.5 μg/m3 and 4.9 μg/m3 respectively. The assumption that the highest 1-hour concentration occurs continuously is unrealistic.
All haul trucks are assumed to have Tier 2 engines. Because of delays, however, six of the engines
will not be manufactured until the Tier 4 standards become effective, at which time manufacturers, will be prohibited from manufacturing Tier 2 engines. NOx emissions for Tier 4 engines are 58% of those of Tier 2 engines. EPA’s Final Rule for Nonroad Engines ((69 Fr 38957 -39206) states that the NOx emission reductions for engines used in mobile machinery are based on engine-based emissions control technology rather than after-treatment methods that utilize oxidation catalysts. The net result of 6 haul trucks with Tier 4 engines is a 21 lb/hr reduction in NOx emissions from haul trucks.
Application of these more realistic assumptions in combination with a NO2/NOx in-stack ratio of 5% would result is substantially lower predicted impacts than those presented in the modeling report.
Section 7.1.5: The report indicates that a three-year average was used to determine attainment of the National Ambient Air Quality Standard (NAAQS) for 2.5 micron-diameter particulate matter (PM2.5). According to EPA’s Model Clearinghouse memorandum of February 26, 2010, the use of a three-year average does not preempt the requirement in Appendix W that five years of National Weather Service (NWS) data be used. The five-year average of modeled impacts serves as an unbiased estimate of the three- year average for the purpose of modeling compliance with the NAAQS. Please clarify that this guidance for PM2.5 modeling was followed.

Clarification:
Section 9.3.1.2.b of 40 CFR 51, Appendix W states the following:
Page 3 of 4
The use of 5 years of NWS meteorological data or at least 1-year of site specific data is required. If one year or more (including partial years), up to five years, of site specific data is available, these data are preferred for use in air quality analyses. Such data should have been subjected to quality assurance procedures as described in subsection 9.3.3.2.
The above citation clarifies that a minimum of 1-year of site specific data is preferred for conducting air impact analyses over 5 years of nearby NWS data. Use of 3-years of site specific data as was conducted in the air impact analyses for the Rosemont project thus exceeds the minimum preferred requirements of Appendix W and does not preempt it.
With regards to the February 26, 2010 memorandum, we have not been able to locate it. We presume, however, that a March 23, 2010 memorandum titled “Modeling Procedures for Demonstrating Compliance with PM2.5 NAAQS” from Stephen D. Page, Director of Office Air Quality Planning and Standards, includes that guidance or a refinement of the guidance provided by the February 26, 2010 memorandum.
This memorandum cites the following in the section titled “Comparison to NAAQS” in the Cumulative Impact Assessment:
For the 24-hour NAAQS analysis, the modeled concentrations to be added to the monitored 24-hour design value should be computed using the same procedure used for the preliminary analysis based on the highest average of the maximum modeled 24-hour averages across 5 years for NWS meteorological data or the maximum modeled 24-hour average for one year of site-specific meteorological data. As noted above, use of the average modeled concentration across the appropriate time period more accurately characterizes the modeled contribution from the facility in relation to the NAAQS than use of the highest modeled contribution, while using the average of the first highest 24-hour averages rather than the 98th percentile (8th highest) values is consistent with the screening nature of PM2.5 dispersion modeling.
The above hypothesizes that the available meteorological data is limited to either five years of NWS data or only one year of site-specific meteorological data. The second highlighted sentence above states that “use of the average modeled concentration across the appropriate time period more accurately characterizes the modeled contribution from the facility than use of the highest modeled contribution”. With regards to the modeling conducted for Rosemont, three years of site-specific data were used. Consequently, averaging of the maximum modeled 24-hour averages across 3 years of site-specific meteorological data more accurately characterizes the modeled contribution than taking only one year of modeled data. The modeling that was conducted for Rosemont thus conforms to EPA’s March 23, 2010 guidance memorandum.
Please call if you have any questions.

Evaluation of Representative Primary NO2/NOx Ratios for use in Modeling Mobile Source Emissions as Part of the Rosemont Copper Project Ambient
Impact Analysis. Executive Summary
Nitrogen-dioxide (NO2) pollution from industrial sources is a product of two distinct processes— primary NO2 from combustion and the formation of secondary NO2 from oxidation of nitric oxide (NO) by ozone (O3) in ambient air. Dispersion models, like AERMOD (USEPA’s guideline dispersion model), can be used to estimate ambient NO2 impacts from plumes emitted by large industrial stacks, by using stack test data for the in-stack model input parameter. However, data from stack tests does not exist for other source types, such as mobile on- and off- road source categories. Therefore, an in-stack equivalent must be selected from available data.
This document discusses the basis for differentiating among data-sampling methods to determine representative primary, or ―in-stack,ǁ NO2/NOx fractions for modeling mobile sources and presents current research to support an in-stack ratio of 5% for Rosemont’s mobile source NOx
emissions.
Introduction
The current short-term NAAQS (National Ambient Air Quality Standard) for NO2 (nitrogen dioxide) became effective April 12, 2010. Industrial sources can demonstrate compliance with the standard by using either source-oriented ambient NO2 monitoring data or by relying on estimates provided by air-quality dispersion modeling. NO2 monitors measure ambient hourly NO2 concentrations, which can be compared directly to the NO2 NAAQS. However, industrial- source emissions are reported as total NOx, which is a composite of NO2 and NO. Air-quality models must, therefore, simulate the dispersion and transformation of NOx to NO2 before any comparisons to the NAAQS can be made. Most photochemical models use elaborate chemical transformation schemes to simulate secondary NO2 formation, but they are generally intended for long-range air-quality studies and not for localized air-quality impacts from industrial sources. In any event, model selection is dictated by federal guidance, which generally limits industrial-source permit modeling to AERMOD (which uses a rather simple NO2 oxidation scheme to simulate NOx transformations).
AERMOD is primarily a steady-state plume-dispersion model; therefore, it must rely on built-in oxidation models like OLM (Ozone Limiting Method) and PVMRM (Plume Volume Molar Ratio Method) to estimate ambient ratios of NO2 /NOx, based initially upon representative NO2/NOx data from in-stack NOx emissions. The ambient NO2 ratio is estimated by computing the sum of the fraction of in-stack NO2 formed during combustion—called the primary NO2/NOx
ratio—with the fraction of secondary NO2, transformed from NO in the ambient air by mixing and by oxidation by ozone. At minimum, AERMOD requires a representative estimate for the primary NO2 fraction. Modeling industrial stacks using either OLM or PVMRM is typically straight forward, since in-stack NOx data collected from compulsory EPA stack testing is usually available. To the contrary, modeling NO2 impacts from mobile sources is not straight forward,

since stack testing does not apply to mobile sources and mobile source plume behaviors is distinctively different from plumes emitted from elevated stacks.
The body of literature from studies pertinent to mobile source NOx emissions is comprised of data collected from a variety of sampling methods. The primary objective of this document is to present representative NO2/NOx estimates, based on only those studies in which primary NO2
was sampled by either direct (in-stack or in-pipe) measurement methods or by methods designed for mitigating oxidation from ambient ozone, via measuring NOx inside of tunnels.
The following reports support a primary NO2 in-stack fraction of 5%
―Nitrogen Oxides Reactions in Diesel Oxidation Catalyst.ǁ – Majewski, et al. Reports a maximum primary NO2 ratio of 5.3%
―The use of tunnel concentration profile data to determine the ratio of NO2/NOx

Discussion
Traditional NOx measurements from power plants are often derived from in-stack measurements, in accordance with USEPA Test Method 7 (1). Stack test data is ideal for oxidation models, since OLM and PVMRM require, as input, the ratio of primary NO2/NOx—representative of NOx
emissions before the exhaust gases leave the stack (2). However, selecting representative in-stack NO2/NOx data for modeling mobile sources can be complicated. Stack testing does not apply to mobile sources, and established EPA mobile-source test methods are not well suited to provide primary NO2 measurements.
For example, EPA’s continuously integrated test method for NOx emissions samples engine-out exhaust, which has been mixed with ambient air and allowed to cool to near ambient temperature (3). Also, EPA’s bag-sample method, where diluted exhaust gas is collected and analyzed at ambient temperature, also allows cooling and is not a representative measure of ―in-stackǁ primary NO2. Since the model’s in-stack parameter requires measurements that are representative of NOx emissions before they leave the stack, data derived from EPA’s test procedures are inappropriate for model input.
There are alternative data sources for mobile-source emissions, but discretion should be used to differentiate samples that are representative of primary NO2 from combustion, from those that

![Page 66: portal.azoah.com · VIA E‐MAIL: Vaidyanathan.Balaji@azdeq.gov December 15, 2017 Mr.Balaji Vaidyanathan Manager, Facilities Emission Control Section Arizona Department of Environmental](https://reader036.fdocuments.net/reader036/viewer/2022071000/5fbc1773013e5f21f87885eb/html5/thumbnails/66.jpg)
may likely include an appreciable degree of oxidation. There are two important considerations for determining appropriate NO2/NOx ratios for off-road diesel vehicles. First, the ratio of NO2/NOx must be representative of primary NO2 formed from combustion—engine-out measurements made inside the tail pipe (in-pipe) are preferred. The second consideration must account for NO2 formed by diesel after treatment technologies, such as Continuously Regenerating Technology (CRT), which reduce particulate emissions but can increase the in-pipe fraction of NO2 by forcing oxidation of NO to NO2 across a catalyst. Most research suggests that diesel engines fitted with CRT can increase the in-pipe NO2 to 30%, on average. However, not all diesel after-treatment technologies have adverse impacts on in-pipe NO2.
The study ―Nitrogen Oxides Reactions in Diesel Oxidation Catalystǁ (4) discussed the influences of platinum and palladium oxidation catalysts on NOx transformations in diesel exhaust from a Caterpillar 3304 mining diesel engine. The apparatus design was comprised of a direct (i.e., in- pipe) sampling method using Fourier Transform Infrared (FTIR) and was set up to allow sampling before and after each catalyst. At a maximum conversion temperature of approximately 380 degrees C, the platinum catalyst increased NO2 from approximately 5 ppm to 25 ppm, while NO was reduced from 625 ppm to 475 ppm. The values are approximations, since the report only provided the data in chart form. However, even with a fourfold increase in NO2, the maximum NO2/NOx ratio was 5.3%. The maximum pre-catalyst NO2/NOx was approximately 3.5% at 150 degrees C, where NO was 200 ppm and NO2 was 7 ppm.
Tunnel sampling methods can also provide an estimate of primary NO2, since the air near the center of long tunnels often has less oxidation potential than ambient air, outside the tunnel. The study ―The Use of Tunnel Concentration Profile Data to Determine the Ratio of NO2/NOx
Directly Emitted from Vehiclesǁ (5) details a procedure for estimating the primary NO2 fraction from NOx measurements made in two separate tunnels; each tunnel was approximately 4 km in length. At the center of each tunnel, atmospheric oxidation potential is limited (albeit not likely entirely absent). Ambient pollutant concentrations are measured inside the tunnel at different locations. Higher NO2/NOx ratios were measured near each tunnel’s entrance and exit. The lowest NO2/NOx ratios (2% to 6%) were measured near the center of each tunnel. Measurements near the tunnels’ centers can be considered very conservative estimates for thermal NO2/NOx, since measurements are made in the open air and at ambient temperatures, yet with very limited oxidation potential.
In a letter provided by Caterpillar, Caterpillar states that emission test procedures for on- and off- road equipment follow applicable regulations. As a general rule, Caterpillar claims that engine- out NO2/NOx can range from 5% to 15% NO2, but that oxidation catalysts and diesel particulate filters can increase the ratio of engine-out NO2. It is unclear, however, if Caterpillar estimates are for engine-out or tailpipe NO2. EPA also suggests that mobile-source NO2 emissions from diesel vehicles with DPF can have elevated NO2/NOx ratios, as compared to non-catalyzed diesel vehicles. In Shorter et al., (6) diesel vehicles fitted with DPF/CRT had an average NO2/NOx ratio of 30%, while ambient measurements from non-catalyzed vehicles were below 10% NO2/NOx.
In section 8.4 of EPA’s ―Risk and Exposure Assessment to Support the Review of the NO2
Primary National Ambient Air Quality Standardǁ (7) AERMOD was set up to model ambient NO2 impacts in Atlanta, GA. OLM was used for roadway and airport emissions, and PVMRM was used for point sources. All sources were modeled with an in-stack ratio of 10%, including

off-highway diesel airport vehicles. Roadways were modeled as large area sources, with length- to-width ratios of 1:100.
In Appendix B - Supplement to the NO2 Exposure Assessment, Section B-3 Philadelphia Exposure Assessment Case-Study (8), NO2 air-quality impacts were modeled in the Philadelphia area, with AERMOD. OLM was used for roadway, fugitive, and airport emissions, including off- highway diesel vehicles, with an in-stack NO2/NOx ratio of 10%. PVMRM was used to model stacks with an in-stack ratio of 10%.
Conclusions
In-stack data is available for industrial stacks, not mobile sources. In-stack NO2/NOx must be representative of exhaust gases before leaving the stack and
before any mixing or oxidation by ambient air has occurred. Typical mobile-source emissions, which are often measured after mixing with ambient
air, are inappropriate for use with OLM or PVMRM. According to data sampled from in-pipe diesel exhaust, the maximum ratio of NO2/NOx
is 5.3%. According to data sampled from a tunnel study, estimates of the primary NO2 fraction
range from 2% to 6%. Reports of NO2/NOx ratios as high as 30% are often reflective of diesel vehicles fitted
with diesel after treatment devices.

The Australian coal mining industry, as with other industries is coming under greaterconstraints with respect to their environmental impacts. Emissions of acid gases such asNOx and SOx to the atmosphere have been regulated for many years because of theiradverse health effects. Although NOx from blasting in open-cut coal mining may representonly a very small proportion of mining operations’ total NOx emissions, the rapid releaseand high concentration associated with such activities may pose a health risk. This paperpresents the results of a new approach to measure these gas emissions by scanning theresulting plume from an open-cut mine blast with a miniaturised ultraviolet spectrometer.The work presented here was undertaken in the Hunter Valley, New South Wales, Australiaduring 2006. Overall this technique was found to be simpler, safer and more successfulthan other approaches that in the past have proved to be ineffective in monitoring theseshort lived plumes. The average emission flux of NOx from the blasts studied was about0.9 kt t�1 of explosive. Numerical modelling indicated that NOx concentrations resultingfrom the blast would be indistinguishable from background levels at distances greater thanabout 5 km from the source.

1. Introduction
Open-cut coal mining is widespread in the upperHunter Valley in New South Wales (NSW) with severallarge mines operating within close proximity to the townsof Muswellbrook and Singleton. Consequently, there iscommunity concern about the potential environmentalimpacts of mining on nearby populations.
Blasting, in particular, has the potential to affect areasoutside the mine boundary and accordingly, vibration anddust emission limits are set in each mine’s environmentallicence. However, gaseous emissions of environmentalconcern, such as nitrogen dioxide (NO2) may also bereleased during blasting operations. Currently, there arevery little quantitative data relating to the magnitude ofthese emissions and it is not yet possible to determine ifthey contribute significantly to ambient levels in the mainpopulation centres.
The explosive ammonium nitrate/fuel oil (ANFO) is usedalmost universally throughout the open-cut coal miningindustry. Under ideal conditions, the only gaseous productsfrom the explosion are carbon dioxide (CO2), water (H2O)and nitrogen (N2).

However, even quite small changes in the stoichiometry(either in the bulk material or caused by localised condi-tions such as moisture in the blast hole, mineral matter orother factors) can lead to the formation of substantialamounts of the toxic gases carbon monoxide (CO) and nitricoxide (NO) as shown.

In addition, some of the NO formed may oxidise in thepresence of oxygen (O2) to produce NO2.

2NO þ O2 / 2NO2 (4)
Often in practice, large quantities of NO2 are released fromblasts which are observed as intense orange plumes.
Although these gases are not considered in their envi-ronmental licences, each mine is required to estimateannual emissions of CO, NOx and SO2 for the NationalPollutant Inventory (NPI), compiled each year by theAustralian government. These estimates are made bymultiplying the amount of explosive consumed by anemission factor which is currently 8 kg t�1 for NOx, 34 kg t�1
for CO and 1 kg t�1 for SO2 (National Pollutant Inventory,1999). These emission factors, however, are based onlimited overseas data and are subject to high uncertainty.
Most of the studies which have examined NOx forma-tion from blasting have used blast chambers. The resultsfrom these studies do not necessarily correlate with what isobserved during actual blasts. Few studies have attemptedto measure NOx emissions under actual field conditions,presumably because of the practical difficulties involved.Plumes from blasting lack confinement, can be very large insize and are affected by prevailing weather conditions.There is also a large quantity of dust associated with theblast and these factors combine to make physical samplingof the plume very difficult. There are also the obvious safetyimplications which restrict access to blast sites. Conse-quently, quantitative measurements of plume characteris-tics are generally unavailable. Nevertheless, it is importantfor mine operators, particularly when their operations areclose to residential areas, to have some method forassessing NOx formation and more importantly, predictingthe severity of the NOx plume. At present predictions of NOx
formation are subjective and are based on the blast engi-neer’s knowledge of the area to be blasted (e.g. rock type,area of the mine, presence of water in the holes, etc.) andthe ratings obtained from blasts performed under similarconditions. Quantitative flux estimations of NOx releasedfrom a blast require measurement of concentrationthrough the plume in both the horizontal and vertical axes.
Some of the options available to make these measure-ments are given in the following sections.
1.1. Physical sampling
Sampling of blasting fumes involves taking a sample ofgas from the plume for subsequent analysis, which could beeither on site or in an off site laboratory. Although physicalsampling could in principle provide sufficient informationto characterise a plume, there are a number of seriouslogistical problems with this approach:
� The size of the plume means that a large number ofsample points would be required to sample across thewidth and height of the plume.
� The force of the explosion and the resulting debriswould restrict the proximity of any sampling packagesto the initial gas release.
� The potential toxicity of the plume; personnel cannotmove through it to take samples, hence samplingstations must be fixed prior to the blast. This means
that the path of the plume must be anticipatedbefore the blast.
1.2. Continuous analysis
Another option is to use portable analysers to measureNOx concentrations in real time. There are, however,disadvantages with this approach since a sample of theplume must be presented to the instrument for analysis.Usually a pump draws air through a small diameter tubeinto the instrument, but to achieve the necessary spatialcharacterisation of the plume, sample tubes would need tobe positioned at various points throughout the plume. Thusmany of the problems identified for the physical samplingwould also apply to the use of continuous analysers.
1.3. Optical methods
There are several optical methods of analysis currentlyavailable that may be applicable to field measurements ofNOx. These include open-path Fourier Transform Infra-RedSpectroscopy (FT-IR), Correlation Spectroscopy (COSPEC)and Differential Optical Absorption Spectroscopy (DOAS).FT-IR has often been used in air pollution studies (e.g.Levine and Russwurm, 1994). It has also been used in minesituations to measure fugitive methane emissions. Kirch-gessner et al. (1993) used open-path FT-IR (op-FT-IR) toestimate methane emissions from open-cut coal mines inthe United States. The technique relies on passing a colli-mated infrared beam through ambient air over a pathlength of up to several hundred metres. In the Kirchgessneret al. (1993) study, the concentration of methane across theplume was measured then wind speed data and a Gaussianplume dispersion model were used to estimate themethane emission rate from the mine. These authorssubsequently developed a modification of their methodwhich improved its accuracy (Piccot et al., 1994, 1996). Theimproved method was essentially the same as describedabove except that methane concentrations were measuredat several elevations to better characterise the plume.
In principle, open-path FT-IR could be used to measureNOx in blast plumes since it is sensitive to NO, NO2, and COalong with other gases. Infrared radiation is also stronglyabsorbed in many parts of the spectrum by both CO2 andwater which are very likely to be present in high concen-trations in blast plumes and this may tend to obscure theNOx signal. High resolution instruments may resolve at leastsome of the NOx absorption lines, however, a more seriousdrawback with op-FT-IR is that the infrared beam would besubstantially attenuated by the dust thrown up by the blast.In the period immediately after the blast when the dustlevel is very high it is likely that the IR beam would becompletely blocked thus making measurements impossible.
Another well established optical method is CorrelationSpectroscopy (COSPEC). The system was first described byMoffat and Milan (1971) and was designed to measurepoint source emissions of SO2 and NO2 from industrialplants but found a niche application in the measurement ofSO2 fluxes from volcanoes (Galle et al., 2002). The COSPECsystem utilises a ‘‘mask correlation’’ spectrometer and wasdesigned to measure vertical or slant columns using

sky-scattered sunlight. By traversing beneath plumes withthe mobile instrument, the concentration of the column iscalculated and, once multiplied by the plume velocity,produces a source emission rate. These instruments arelimited to detecting only those species where masks areavailable. They also suffer from interferences from otheratmospheric gases and light scattering from clouds oraerosols that can produce errors in column densities(Chalmers Radio and Space Science, website).
The DOAS technique is a relatively new technique that isgaining widespread acceptance as an air pollution moni-toring method. Like the open-path FT-IR method, the DOAScan simultaneously measure concentrations of a number ofspecies over path lengths which typically range fromhundreds of metres to kilometres.
A DOAS, configured as an ‘active system’, Fig. 1, has threemain parts – a light emitter, a light receiver and a spec-trometer. The emitter sends a beam of light to the receiver(in some cases the emitter and receiver are contained in thesame unit and the light beam is reflected off a remotelylocated passive reflector). The light beam contains a rangeof wavelengths, from ultraviolet to visible, althoughinstruments are now available with an infrared source,which extends the range of compounds that can bedetected. Different pollutant molecules absorb light atdifferent wavelengths along the path between the emitterand receiver. The receiver is connected to the spectrometerwhich measures the intensity of the different wavelengthsover the entire light path and through the data systemconverts this signal into concentrations for each of thespecies being monitored.
DOAS instruments are routinely used to measure SO2,NO2 and O3.
More recently, advances in miniaturising UV–vis spec-trometers has lead to the development of much morecompact DOAS units, configured as a passive system (Fig. 1),which have come to be known as ‘‘mini-DOAS’’. The mini-DOAS system has so far been used mainly in the study ofSO2 fluxes in volcanic emissions (McGonigle et al., 2003).
2. Methodology
2.1. Field measurements
A portable DOAS (mini-DOAS) manufactured by Reso-nance Ltd was used in this study. The instrument covers
a spectral range of 280–420 nm and can measure sub-partper million levels of NO2 and SO2. The unit, whichcomprises a telescope, scanning mirrors, calibration cellsand a miniature CCD array spectrometer (Ocean OpticsUSB2000 spectrometer), is housed in a small packagewhich is mounted on a tripod. Calibration of the instrumentwas carried out using the internal calibration cell. Theconcentration of the cell was equivalent 50 ppm m. No SOx
measurements were undertaken.Data collection and processing were performed by
Ocean Optics OOIBase32 software loaded in a laptopcomputer. This results in a more compact system that iseasier to deploy at mine sites and provides greater flexi-bility in positioning the instrument in relation to the blastplume.
Prior to each monitored blast, a dark spectrum wascollected by blocking light from entering the spectrometerand a scan was performed. To produce a reference spec-trum, a further scan was performed in a clear sky back-ground which contained background absorption from NO2.The reference spectrum was required in order to determinethe increase in concentration of NO2 above ambient levelsin the blast plumes.
The plume resulting from each blast was tracked withthe spectrometer until the NO2 concentration was indis-tinguishable from the surrounding sky. During each fieldmeasurement, the mini-DOAS and a video camera werepositioned a safe operating distance from the blast at alltimes.
NO2 concentrations in the plume were calculated bysubtracting the dark spectrum from the measured spec-trum and the reference spectrum using the suppliedsoftware.
The results obtained from the mini-DOAS are a path-averaged NO2 concentration profile measured in units ofparts per million metre (ppm m). The mini-DOAS resultsmust be divided by the path length through the plume toyield a concentration. To estimate the amount of NO2
released from each blast it was necessary to multiply theconcentration by the volume of the plume. Hence it wasnecessary to estimate the dimensions of each plume.
All of the blasts monitored were video-taped using atleast one, and sometimes two, video recorders. Thedistances between the cameras and the blast weremeasured by locating their positions with a handheld GPSreceiver.

Wind speed and directional data used to plot thedirectional path of the plume were obtained from a seriesof meteorological stations located around the mining lease.Simple trigonometry was employed to determine thedistance from the video camera to the plume at thecorresponding time intervals.
A rudimentary method of photogrammetry was thenused to estimate the size of the plume based on still imagesextracted from the videos. Ratios of the plume to picturesize in both the vertical and horizontal planes were made.
Once the plume to camera distance and the constrainingangle for the plume is known, a crude three-dimensionalestimate of the plume dimension was calculated using basictrigonometric functions. An example of the dimensionsdetermined for a plume using this method is shown in Fig. 2.
Ground level measurements were carried out usinga Greenline 8000 portable gas analyser. This instrument iscapable of continuous, simultaneous analysis of O2, CO2,CO, SO2, NO and NO2. It is battery powered and can operateunattended for up to about 2 h. The instrument wascalibrated against a standard gas mixture before each use.Data were logged on a laptop computer connected to theinstrument.
For each experiment, the instrument was set updownwind of the blast in a location where the plume wasexpected to pass, but far enough away to avoid flying debris.The inlet probe was fixed at about 2 m above ground level.
It must be noted that selecting an appropriate locationfor the instrument was often difficult. In many cases,the wind conditions were quite variable, especiallywithin the pit so it was not always possible to correctlyanticipate the path of the blast plume. As well, the layout ofthe mine pit and safety considerations imposed constraintson where the instrument could be placed. Because of theseproblems, the plumes from many of the blasts did not passover the analyser and data was not recorded.
2.2. Modelling
A simple modelling exercise was undertaken for thisstudy to determine if the release of NO2 from a blast couldbe of detriment to persons exposed to the plume within
5 km of the release. The results of this study are indicativeand based on the assumption that the model used isappropriate. Modelling generally relies on local observa-tional data to confirm the performance of the model. Thedifficulty in measuring emissions from mining blasts hasmeant that in this case the model is used as an indicatorrelying on the verifications used in the development of thechosen model. For this reason we have modelled concen-trations directly downwind of theoretical blasts with AFTOX(Kunkel, 1991), a USEPA approved dispersion model (http://www.epa.gov/scram001/dispersion_alt.htm#aftox). Theoriginal DOS based QuickBasic code was transformed intoExcel macros to enable many scenarios to be run.
AFTOX is a Gaussian Puff model developed for theUnited States Air Force to assess real time toxic chemicalreleases. The model uses information from US Air WeatherService (AWS) stations to calculate dispersion based onmeasured atmospheric conditions. As for all Gaussianmodels, the spread of pollutants is governed by dispersioncoefficients in the horizontal (sy) and vertical (sz) direc-tions. These coefficients depend on the atmosphericstability derived from the AWS data. In this study, thescenarios were modelled by predefining the wind speedand atmospheric stability classes. The wind speedsmodelled ranged from very low (0.5 m s�1) to moderate(10 m s�1). Stability was modelled in six steps representingthe standard Pasquill-Gifford stability classes, i.e. A–F,where A, B and C represent unstable conditions (where A isthe most unstable), D is neutral and E and F are stableconditions. These stability classes are used to categorise therate at which a plume will disperse. Unstable conditionsmight be found on a sunny day with light winds leading torapid plume dispersion while the stable conditions mayoccur in clear skies with light winds and perhapsa temperature inversion present. Plume spread is slow inthese circumstances.
AFTOX is operated by assuming an emission releasefrom a single location. The emissions can be eithercontinuous or instantaneous. In this study AFTOX was usedto describe an area source by representing it as a largenumber of individual points. The area of the emission (i.e.the area over which the explosives were distributed) was

assumed to be 100 m� 200 m based upon sizes commonlyobserved during the field measurements. The area wassubdivided into 10 m� 10 m units. Each square was rep-resented by a point source with its source at the centre. Intotal, the area was modelled as 231 separate point sources(see Fig. 3). The total flux of emissions for the source was setat 100 kg. To estimate the maximum concentration andpollutant exposure values, the values should be multipliedby an appropriate scaling factor.
One hundred and twenty scenarios were modelled inwhich the 100 kg of emissions were spread randomlythroughout the source area. A multi-stage process wasemployed for this task. In the first step, the total maximumnumber of points emitting was determined. This wasdefined by a random number between 20% and 80% of themaximum number of sources (in this case 231). The rangechosen was an estimate from the portion of blasts thatappeared to fume in conditions witnessed during this study.The total emission was then divided by this number. Eachportion of the total emission was then placed randomlywithin the emission area. This process allowed certainpoints to receive multiple portions of the total emissionsenabling the formation of hot spots. An example of oneemission grid (Scenario 1 of 120) is displayed in Fig. 4.
Concentrations were determined for each of the 120emission scenarios at distances of 200 m, 300 m, 400 m,500 m, 750 m, 1 km, 1.25 km, 1.5 km, 2 km, 2.5 km, 3 km,4 km and 5 km from the origin of the source. A concen-tration was determined for a number of discrete times thatencompassed the complete plume travelling past thereceptor. Further the concentrations were determined at 21locations 10 m apart in a plane parallel and directlydownwind of the source area (see Fig. 3). An averageconcentration from each of the receptors was determined;in this case with N equal to 21.

3. Results and discussion
3.1. Field measurements
Plume measurements were made using the mini-DOASspectrometer at two open-cut mine sites located inthe Hunter Valley. The combination of the spectral analysisand the plume estimation technique allowed for NO2
concentration and mass flux estimates to be maderemotely, totally eliminating the requirement of physicalsampling.
An example of the spectral output produced by themini-DOAS is shown in Fig. 5. The spectral output consistsof the NO2 concentration (ppm m) as a function of time. Thefigure also contains a series of photographs depicting theformation of a blast plume at time intervals of 70, 110, 163,250 and 350 s post-blast initiation. It is worth noting thechange in intensity of the colour of plume and size asa function of time.
Reliable concentration measurements with the mini-DOAS may only be made when the spectrometer is aimedinto a sky background above the horizon from the point ofobservation. In this example, a peak concentration of580 ppm m was achieved in 163 s post-blast initiation(third image from the left). At this time the plume has risenabove the horizon from the point of observation. The plumeto mini-DOAS distance at this stage is approximately500 m, with an estimated plume depth of 105 m. Thisresults in a NO2 concentration of 5.6 ppm at that particularstage of the plumes’ dispersion.
After 350 s, the plume is barely visible and is now esti-mated to be approximately 650 m from the mini-DOASunit. The plume depth has increased to 125 m with

a corresponding increase in plume volume by a factor oftwo. This expansion of the plume corresponds to a decreasein NO2 concentration to 2.8 ppm.
At 360 s the plume was no longer visible to the eye andwas lost for a short period of time to the mini-DOAS. This,however, was rectified with scanning of the sky with thespectrometer until the invisible plume was tracked fora further period.
Results for all plumes monitored during field work atboth mine sites are given in Table 1. The table gives the peakNO2 concentration as measured by the mini-DOAS abovethe horizon. Also given in the table is the plume volume atpeak concentration and the calculated mass of NO2
released from the blast. The mass of ANFO typically used ina blast was on average 210 tonnes, ranging from 60 to
565 tonnes. The explosive was distributed over an area oftypically 200 m� 100 m containing approximately 200bole holes with 200 mm diameter and to a depth of 25 m.
From the table the maximum NO2 concentrations werefound to range from 0 to about 7 ppm. This range ofconcentrations translated to 0–63.3 kg of NO2 in the plume.However, no correlation can be made between blast chargeand NO2 levels.
During the measurements with the mini-DOAS groundlevel measurements were also carried out using a portablecombustion gas analyser (Greenline 8000) to augment theairborne measurements made by the mini-DOAS. For NO2
the ground level measures were higher than thoseobserved using the mini-DOAS at higher altitudes. Whenthe results of both measurement methods were applied to

relationship enabled the estimation of the NO fluxes in theblast plume with a reasonable level of confidence.
The results obtained in this study are the only publishedquantitative data available on blast plume gas compositionthat the authors are aware of and it is useful to comparethem to the emission factors currently used for NPIestimates.
Based on the NO2 measurements and estimates of NO,the flux for NOx was calculated to be in the range of 0.04–5.3 kg t�1 ANFO. The average flux level for all the blastplumes measured was 0.9 kg t�1. This figure is considerablylower than the current NPI emission factor which is 8 kg t�1.
3.2. Modelling
Results of the modelling runs are summarised in Table 2and show the peak NO2 concentrations (ppm) at variouspoints downwind of the blast for the six atmosphericstability classes considered.
Examples of the modelled data are plotted in Fig. 6 andFig. 7. In Fig. 6 a plot is displayed for the concentrationestimate of one scenario at a distance of 200 m from thesource origin and for a wind speed of 2 m s�1 and a stabilityclass C. In this plot 21 lines are shown representing the dosereceived directly downwind of the source at the locationsdisplayed in Fig. 3. In this figure it is apparent that there isa considerable difference in the concentration predicted ateach of the 21 receptors. It should be noted that thedistance of 200 m is defined from the origin of the sourcearea (0, 0) as displayed in Fig. 3. At this distance emissionsources at 100 m will cause significantly higher concen-trations than those occurring at positions toward theorigin. In comparison the concentrations predicted at thereceptor array 1 km from the source show more normallydefined distributions with maxima occurring towards themiddle receptors as a result of crosswind diffusion.
Receptors toward the edge of the sample array receive lesscrosswind influence and are, therefore, smaller in concen-tration. Also apparent in these two figures is the consid-erable difference in the predicted peak concentrations withthe values at 1 km up to 25 times lower than at 200 m.When viewing Table 2, the peak values at 5 km approachambient levels for all but the most stable conditions whichare quite commonly over predicted with Gaussian models.For future studies it is recommended that a long pathtechnique on a mining lease boundary may provide botha measure of the model accuracy as well as a direct measureof the impact in areas directly surrounding the mining area.
The data presented in this study represent a dose directlydownwind of the source and as such are a worst casescenario for exposure. The averages of the 21 receptors (i.e.the average concentration directly downwind of the source)for each of the 120 scenarios modelled were used to deter-mine the selected data. The number of scenarios modelledwas arbitrarily chosen to allow 10 scenarios to be run oneach machine in a cluster of 12 computers. The maximumconcentration in Table 2 is the maximum ensemble averageobtained from the average of the 21 receptors for the 120scenarios modelled. Maximum concentrations at individuallocations directly downwind of hot spots are obviouslyhigher than the values reported in this table.
When viewing Table 2 it is apparent that the peakconcentrations drop dramatically as the receptor movesaway from the source. It is also apparent that the peakconcentrations vary little as a function of wind speedalthough the plume width will vary. In AFTOX a downwindconcentration is determined in two steps. In the first stepthe size of the initial plume envelope is estimated. In itsdefault mode AFTOX determines the size of the envelope(assumed to be a cylinder of equal height and width) fromthe magnitude of the emission rate. In this report the size isset at 10 m to match the grid structure used for the area

source. AFTOX in this regard ignores the effect of windspeed on the size of the initial envelope and as such theinitial concentration of the plume is identical irrespectiveof wind speed by ignoring longitudinal (i.e. downwind)spread of the initial release. In the second step theconcentration downwind of the initial release is deter-mined by estimating the growth of a puff in three dimen-sions which in this case explicitly includes longitudinalplume spread which is assumed to be equal to the degree ofcrosswind spread. The degree of this spread is determinedsolely from the prescribed atmospheric stability classwhich ignores any wind speed dependence.
While the peak concentrations are similar, the dosereceived at a receptor is linearly dependent on wind speed.Emissions released into an atmosphere with higher windspeeds result in a receptor receiving doses for a smallerperiod of time. It should be noted that some of the differ-ences in the peak concentrations displayed in Table 2 resultfrom the number of discrete time steps used to calculatethe concentrations. This was set at 25 intervals between theonset and finish of a plume as it passes by the receptor. Thistime is dependent on atmospheric stability and thedistance from the source. In AFTOX, the puffs are assumedto disperse in the direction of plume travel proportionallywith the degree of crosswind spread. As such, portions ofthe plume arrive before and after the main bulk of theemissions and the effect clearly demonstrated in Figs. 6 and7. The moderate number of discrete times modelled tocapture this effect while generally adequate may have ledto a degree of variation particularly at larger distances fromthe source.
Again it should be noted that the modelled figuresassume an area wide flux of 100 kg which is larger thanobserved in the blast recorded during this study. It shouldalso be noted that while some of the concentrations arehigh close to the source the concentration at a particular
location occurs for a brief period of time which is deter-mined by the wind speed.
4. Conclusions
A portable open-path spectroscopic method was foundto be effective for measuring NO2 emissions from blasting.Overall this technique was found to be simpler, safer andmore successful than other approaches that in the pasthave proved to be ineffective in monitoring these shortlived plumes.
Quantitative measurements of NO2 in plumes fromblasting were made at two open-cut mines. The resultsshowed that NO2 was present in most of the plumes but inrelatively low concentrations (typically ranging between0 and 7 ppm). The highest concentration measured duringall the field campaigns was about 17 ppm at ground level.
Based on field measurements, the emission factorcurrently used in compiling the Australian NationalPollutant Inventory was found to be approximately eighttimes greater than that observed in our investigation. Thiswould suggest that an over estimation of NOx is made if thecurrent factor is used.
Numerical modelling of the behaviour of plumesresulting from blasting was made to assess the possibledownwind concentrations of NO2. These results werecompared to ambient NOx measurements made inMuswellbrook.
� Modelling results were consistent with concentrationmeasurements within the plumes at relatively shortdistances from the blast (i.e. up to about 1 km).
� Ambient monitoring did not detect NOx events thatcould be attributed to individual blasts. Modellingsuggested that these emissions would be very low at

1. PARTICLE SIZE DISTRIBUTIONS The following sections describe the methodology used to estimate the particle size distributions for
various emission sources.
1.1 Haul Roads Section 13.2.4 of AP 42 lists the emission factors for emissions from unpaved roads. These emission
factors were used to determine the distribution of emissions for particles with nominal diameters less
than 30, 10 and 2.5 m. Figure E.1 shows the distribution.
Figure E.1 Average size distribution for air borne dust generated by haul trucks for entire
study period.
A 2nd degree polynomial equation was used to fit the data and determine particle size distributions for
use with haul road emissions from the Rosemont mine. Table A.1 shows the calculated particle size
distribution that will be used for haul road emissions.

Introduction
ADEQ Guidance to ACFY on Ozone Impact Analysis January 7, 2016
Based on preliminary information provided by Arizona Clean Fuels Yuma (ACFY), it is likely the proposed
refinery project will trigger PSD review for ozone. The Project area is currently designated as
unclassifiable/attainment with respect to the 2008 ozone NAAQS, and the Project NOx and voe emission
increases will be approximately 250-300 tpy each. Therefore, there will be a PSD requirement to
demonstrate that the Project emissions do not "cause or contribute" to a vio lation of the ozone NAAQS.
EPA recently revised the ozone NAAQS from 75 parts per billion ("ppb") to 70 ppb on an 8-hr averaging
interval; this more stringent standard will take effect December 28, 2015. 80 Fed. Reg. 65292. In the final
ozone NAAQS rule, EPA also amended the PSD rules to allow sources to be grandfathered with respect to
the new NAAQS (i.e., to require only that the source owner/operator demonstrate compliance with the
2008 ozone NAAQS) if either the permit application was deemed complete before the new ozone NAAQS
rule was signed in October 2015, or if a draft permit was issued before the new ozone NAAQS became
effective in December 2015. 80 Fed. Reg. 65292 at p. 65433. Neither of these grandfathering provisions
will apply to the ACFY Project as a permit application has not yet been received, therefore this Project will
have to demonstrate that the Project emissions do not cause or contribute to a violation of the 2015
ozone NAAQS.
ACFY has collected PSD pre-construction ozone data at the Project site for a one year period that indicates
the 2015 NAAQS concentration is being exceeded in the area. In addition, three recent years of ozone
data from ADEQ operated ozone monitors in the area also indicate exceedances of the 2015 NAAQS.
Therefore, the Project area may be designated non-attainment with respect to the 2015 ozone NAAQS in
the future. However, given the time frame for the designation process, it is very likely that the PSD
permitting requirements for ozone will still be in effect during the review and approval of the ACFY Project
permit application. Therefore, ACFY will have to demonstrate that the Project's emissions do not cause
or contribute to a violation of the 2015 ozone NAAQS.
Cause or Contribute Criteria and Significant Impact Levels
Historically, under the de minimis doctrine, EPA and the courts have allowed the use of several types of
"screening tools" in the permitting process. These tools include the Significant Emissions Rates (SERs) and
the Significant Impact Levels (SILs). The SERs, defined in tons per year (tpy) for each regulated pollutant,
are incorporated in the codified PSD and NNSR rules and are used to determine whether the emissions
increase from any proposed source or modification can be excluded from review entirely. Similarly, the
SILs, which are incorporated in the codified rules for certain pollutants and are expressed in terms of
ambient concentration, are used as a quantitative representation of the ambiguous phrase, "cause or
contribute to." A source that will cause an increase in concentration in an area that is violating a NAAQS
is deemed not to "cause or contribute" to the violation if its contribution is less than the SIL. (See: A.A.C.
R18-2-406(A)(5)(b); 40 CFR § 51.165(b)(2); Section Ill.A of appendix S to 40 CFR part 51.)
Under the PSD program air quality impact analysis process, SILs are used first to determine whether a
Project's ambient impact of a particular pollutant is significant enough to warrant a complete source
PNB000832
![Page 94: portal.azoah.com · VIA E‐MAIL: Vaidyanathan.Balaji@azdeq.gov December 15, 2017 Mr.Balaji Vaidyanathan Manager, Facilities Emission Control Section Arizona Department of Environmental](https://reader036.fdocuments.net/reader036/viewer/2022071000/5fbc1773013e5f21f87885eb/html5/thumbnails/94.jpg)
impact analysis. If a complete analysis is required, and if a violation of a NAAQS is predicted in that
analysis, the SILs are then used to determine whether the source's impact is considered to "cause or
contribute" to that violation. See, for example, 80 Fed. Reg. 65292 at p. 65441.
EPA's October 1, 2015, implementation memo for the new 2015 ozone NAAQS notes the importance of
the SI Ls with respect to implementing the ozone NAAQS under the PSD program:
There are a number of existing program tools that can be used to help facilitate the permitting
process, and the EPA continues to work with stakeholders on others that will improve the
permitting process while assuring attainment and protection of the ozone standards. These
include the use of emission offset programs and significant impact levels (S/Ls) for ozone for PSD
permitting. The existing "PSD offsets" tool continues to be available for permit applicants and
reviewing authorities to address ozone impacts from a proposed source or modification, including
in an area that is not designated nonattainment but where ambient monitoring data shows ozone
concentrations that exceed tjJe revised NAAQS. We believe that S/Ls and related "screening tools"
are useful in determining the extent to which an ambient impact analysis must be completed to
make the required demonstration for the applicable pollutant. We intend to provide additional
guidance on these screening tools in the near future. {Internal footnote omitted.]
Development of an Interim Ozone SIL
The codified Arizona major NSR rules do not specify a SIL or any other comparable de minimis threshold
for the ozone air quality impact analysis. Similarly, no such provisions have been established in the federal
major NSR rules nor have there been any EPA policy statements of general applicability. EPA is in the
process of developing an ozone SIL. 80 Fed. Reg. 65292 at p. 65441. EPA also has announced its intent to
introduce a new de minimis tool, specifically for ozone and PM2.s precursors, called Model Emissions Rates
for Precursors (MERPs). 80 Fed. Reg. 45340 at p. 45347. These federal provisions, whether established
through rulemaking or policy, are not expected to be finalized at the time of permitting the ACFY project.
Where no SIL has been established by rule or by generally applicable policy, PSD permitting authorities
may need to develop interim SILs. These interim SIL values must be reasonable and supported by an
administrative record. See, for example, final order of the EPA Environmental Appeals Board (EAB) in PSD
Appeal Nos. 98-27 and 98-28, Sept. 9, 1999, upholding the decision of the Indiana Department of
Environmental Management (IDEM) to apply an ozone SIL of 3 ppb ("The mere fact that EPA has not set
a significant impact level for ozone does not, without more, demonstrate clear error or an abuse of
discretion on the part of IDEM in using significant impact levels for ozone in the context of this case.").
See, also, final order of the EPA Administrator denying Petition Nos. Vl-2010-05, Vl-2011-06, and Vl-2012-
07, Jan. 30, 2014, with respect to claims that the Louisiana Department of Environmental Quality acted
inappropriately in using SILs to excuse predicted violations of the Class I S02 increment ("EPA has long
interpreted and continues to interpret this ambiguity in the statute to permit the use of SILs to determine
if the impact from a source contributes to an existing violation.")
PNB000833
![Page 95: portal.azoah.com · VIA E‐MAIL: Vaidyanathan.Balaji@azdeq.gov December 15, 2017 Mr.Balaji Vaidyanathan Manager, Facilities Emission Control Section Arizona Department of Environmental](https://reader036.fdocuments.net/reader036/viewer/2022071000/5fbc1773013e5f21f87885eb/html5/thumbnails/95.jpg)
EPA established an interim 1-hr N02 SIL in their June 29, 2010 memorandum Guidance Concerning the
Implementation of the 1-hour N02 NAAQS for the Prevention of Significant Deterioration Program, and
later an interim 1-hr S02 SIL in their August 23, 2010, memorandum General Guidance for Implementing
the 1-hour S02 National Ambient Air Quality Standard in Prevention of Significant Deterioration Permits,
Including an Interim 1-hour S02 Significant Impact Level. In these memoranda EPA described the basis
and historical precedence for establishing these short-term SI Ls at values equal to 4% of the corresponding
NAAQS. Using this same logic, it is reasonable and consistent with previous EPA actions for ADEQ to
establish an interim ozone SIL at 4% of the 2015 NAAQS, equal to 2.8 ppb for an 8-hour average. This is
the same value (4% of 2008 NAAQS) that IDEM established as an interim ozone SIL which EAB upheld.
Recent EPA modeling guidance for PM2.s has suggested that the PM2.s SILs should only be used as a
screening technique for determining when a Project requires a cumulative impact analysis when the
difference between the NAAQS and the existing air quality is greater than the SIL concentration (herein
referred to as the delta test). See EPA's Guidance for PM2.s Permit Modeling, EPA-454/B-14-001, May
2014. Whiie this would of course result in extra conservatism, it must be noted that this is inconsistent
with how EPA and ADEQ have applied the SILs in the past. No explanation has been offered by EPA for
this seemingly arbitrary shift in policy. Moreover, and of particular note with respect to an ozone PSD
analysis, EPA has not suggested application of the "delta" test for any pollutant other than PM2.s.
Additionally, the PM2.s modeling guidance does not suggest that the SILs cannot be directly used to
determine if a source "causes or contributes" to a violation of the NAAQS during a cumulative analysis. In
summary, the SI Ls have been historically been used to determine when a source "causes or contributes"
to a violation of the NAAQS, both in attainment areas and in non-attainment areas, without the "delta"
test as suggested by the new EPA PM2.s guidance.
EPA Guidance on Single Source Ozone Impact Analysis
On January 4, 2012, the EPA granted a petition submitted on behalf of the Sierra Club that requested the
EPA initiate rulemaking to establish air quality models for ozone and PM2.s for use by all major sources
applying for a PSD permit. In granting that petition, EPA explained that the "complex chemistry of ozone
and secondary formation of PM2.s are well documented and have historically presented significant
challenges to the designation of particular models for assessing the impacts of individual stationary
sources on the formation of these air pollutants" and further explained that "[b]ecause of these
considerations, the EPA's judgment in the past has been that it was not technically sound to designate
with particularity specific models that must be used to assess the impacts of a single source on ozone
concentrations".
EPA's current approach to assess ozone impacts of an individual source is performed on a case-by-case
basis in consultation with the appropriate EPA Regional Office and/or permit reviewing authority. Section
5.2.1.c of the current 40 CFR Part 51 Appendix W (the Guideline on Air Quality Models) states that the
"[c]hoice of methods used to assess the [ozone] impact of an individual source depends on the nature of
the source and its emissions." There is currently not a preferred or recommended analytical technique or
modeling system to perform ozone compliance demonstration assessments for individual sources. Some
assessments have been completely qualitative in nature; while others have utilized photochemical grid
PNB000834
![Page 96: portal.azoah.com · VIA E‐MAIL: Vaidyanathan.Balaji@azdeq.gov December 15, 2017 Mr.Balaji Vaidyanathan Manager, Facilities Emission Control Section Arizona Department of Environmental](https://reader036.fdocuments.net/reader036/viewer/2022071000/5fbc1773013e5f21f87885eb/html5/thumbnails/96.jpg)
models as part of the assessment. Through the consultation process, a modeling protocol should be
developed by the permit applicant and approved by the appropriate permitting authority to ensure that
the analysis conducted will conform to the recommendations, requirements, and principles of Section
10.2.1 of the current Guideline.
In the July 29, 2015 proposed revision to the Guideline, the EPA has stated that advances in photochemical
modeling indicate it is now reasonable to propose more specific guidance that identifies particular models
or analytical techniques that may be used under specific circumstances. The degree of complexity varies
depending on the nature of the source, its emissions, and the background environment. EPA has proposed
a two-step demonstration approach for addressing single-source impacts on ozone and secondary PM2.s.
The first step involves use of t echnically credible relationships between precursor emissions and a source's
impacts that may be published in the peer-reviewed literature; developed from modeling that was
previously conducted for an area by a source, a governmental agency, or some other entity and that is
deemed sufficient; or generated by a peer-reviewed reduced form model. The second step involves
application of photochemical grid models. The appropriate method for a given Project should be selected
in consultation with the reviewing authority and be consistent with EPA guidance. To implement these
proposed changes to the Guideline related to addressing ozone and secondary PM2.s impacts, the EPA
intends to pursue a separate rulemaking to establish new values for PM2.s Significant Impact Levels (SI Ls)
and to introduce a new demonstration tool for ozone and PM2.s precursors referred to as Model Emissions
Rates for Precursors (MERP). EPA intends that the MERPs will represent a level of precursor emissions
that is not expected to contribute significantly to concentrations of ozone or secondarily formed PM2.s.
Based on the present understanding of the atmospheric science of ozone and secondary PM2.s formation,
the MERP values will likely be higher than the SERs.
EPA's current PM2.s modeling guidance provides for a three tier approach to address secondary PM2.s with
(1) a qualitative assessment; (2) a hybrid qualitative/quantitative assessment utilizing existing technical
work; and (3) a full quantitative modeling exercise. The EPA expects that MERPs will replace the first tier
as the qualitative assessment.
EPA is currently performing and reviewing single-source photochemical modeling studies and other PM2.s
and ozone research to develop MERPs for PM2.s and ozone precursors (ozone precursors include the PSD
regulated pollutants NOx and VOC). Some of these studies are summarized below, along with findings
related to the ambient ozone impacts for sources with NOx and voe emissions on the order of 300 tpy
(similar to the current estimates for the ACFY Project).

Environ International Corporation, September 2012.
Two CAMx analyses of Electric Generating Units (EGUs) and Oil and Gas Developments were
performed. For the first modeling analysis, EGUs with greater than approximately 5000 tpy
combined of NOx and S02 resulted in 8-hr ozone impacts of 6 to 13 ppb, while EGUs with
approximately 150 tpy of NOx emissions resulted in 8-hr ozone impacts of approximately 1 ppb.

![Page 97: portal.azoah.com · VIA E‐MAIL: Vaidyanathan.Balaji@azdeq.gov December 15, 2017 Mr.Balaji Vaidyanathan Manager, Facilities Emission Control Section Arizona Department of Environmental](https://reader036.fdocuments.net/reader036/viewer/2022071000/5fbc1773013e5f21f87885eb/html5/thumbnails/97.jpg)
In the second eAMx analysis, EGUs with greater than 1750 tpy of NOx resulted in 8-hr ozone
impacts ranging from 5 ppb to 17 ppb, while EGU sources with NOx emissions of 660 tpy and
smaller resulted in 8-hr ozone impacts less than 1.1 ppb. For Oil and Gas Scenario OG3 with 290
tpy NOx and 90 tpy voe emissions, the 8-hr ozone impact was 1.5 ppb.
lnteragency Workgroup on Air Quality Modeling Phase 3 Summary Report: Near-Field Single
Source Secondary Impacts. EPA-454/P-15-002, July 2015
This report includes examples of single source impacts in two urban areas, Atlanta and Detroit. A
photochemical grid model was applied with baseline emissions and subsequent additiona l
simulations where a new hypothetical source was included with a fixed precursor emission rate.
The simulations with the additional hypothetical source were compared with the baseline
simulation where the hypothetical source is not included (e.g. brute-force difference) and single
source impacts are estimated for 03 and secondary PM2.s. Impacts tend to be highest within 15
km the source and decrease as distance from the source increases. The maximum single-source
8-hr ozone impact is less than 0.5 ppb for all cases with NOx and voe emissions over the range of
100 to 300 tpy (each).
This report also includes a review of existing research and observational studies published
between 2005 and 2015 relating to single source precursor emissions and downwind ozone
impacts. The studies indicate that 8-hr ozone impacts are on the order of 1 ppb for NOx emission
sources of up to 500 tpy. The peak 8-hr ozone impact reported in literature was approximately
33 ppb for a very large NOx source ("'14,000 tpy) in the Louisiana/eastern Texas area.
A Screening Method for Ozone Impacts of New Sources based on High Order Sensitivity Analysis
of CAMx Simulations for Sydney, ENVIRON Corporation, EPA's 10th Conference on Air Quality
Modeling, March 13-15, 2012
This study developed a method for estimating single-source ozone impacts in the Sydney Australia
area. Severa l hypothetical new sources were modeled using eAMx and both a sensitivity test
method (HDDM) and a brute force approach to develop the relationship between ozone impacts
as a function of NOx and voe emissions. A 5000 tpy source was modeled assuming only NOx, only
voe, and a mixture of the two pollutants. The reported maximum ozone 1-hr impact was less
than 1.6 ppb at any grid cell.
In summary, these studies indicate that sources with NOx and voe emissions on the order of 300 tpy
(similar to the AeFY Project) would likely result in ozone impacts below an interim ozone SIL established
at 2.8 ppb.
Requirements for AeFY Ozone Impact Analysis
Based on the current EPA Guidelines, the AeFY ozone impact analysis methodology should be determined
on a case-by-case basis in consultation with the appropriate EPA Regional Office and/or permit reviewing
authority. Given the nature of the source and level of emissions, it is likely that the appropriate level of
PNB000836
![Page 98: portal.azoah.com · VIA E‐MAIL: Vaidyanathan.Balaji@azdeq.gov December 15, 2017 Mr.Balaji Vaidyanathan Manager, Facilities Emission Control Section Arizona Department of Environmental](https://reader036.fdocuments.net/reader036/viewer/2022071000/5fbc1773013e5f21f87885eb/html5/thumbnails/98.jpg)
analysis would be qualitative in nature. ACFY could summarize the ozone impacts reported for similarly
sized sources in the literature, and demonstrate that the impacts are not likely to cause or contribute to
a violation of the 2015 NAAQS (because the existing air quality is already above the 2015 NAAQS
concentration, this means that ACFY ozone impacts would need to be below an interim SIL concentration).
Using EPA's current proposed guidance, the ACFY ozone impact analysis methodology could utilize a tier
2 "hybrid qualitative/quantitative assessment" approach. The assessment should address the topics
discussed in Section 111.2.1 of EPA's PM2.s Modeling Guidance. This hybrid assessment involves the use of
technically credible relationships between precursor emissions and a source's impacts that have been
published in peer-reviewed literature or by governmental agencies. For example, based on the brief
analysis of ozone modeling studies discussed previously, it could be concluded that sources with NOx and
voe emissions similar to ACFY would likely result in ozone impacts below an interim 8-hr ozone SIL of 2.8
ppb.
As EPA has noted in their PM2.s modeling guidance, it is anticipated that only a few situations will require
explicit Tier 3 photochemical grid modeling. Given the relatively modest Project NOx and VOC emissions
for the ACFY Project, it is not likely that this Project is one of the few situations for which Tier 3
photochemical grid modeling is warranted.
