### 1 1 INTRODUCTION

1.1 Purpose

Development of an emissions inventory is an important foundation for performing regional scale atmospheric modeling for regulatory air quality management. The accuracy of the atmospheric model’s prediction of air quality depends, in pa rt, on the accurate representation of emissions from a variety of source sectors including point , area, non-road, on-road and biogenic sources. Electric generating units (EGUs) are an important point source sector a nd are often considered for controls to meet air quality objectives. Theref ore, it is especially important to accurately represent and document EGU emissions and associated characteristics in a regulatory modeling application.

This report describes the development of futu re year EGU emission estimates for use in MidAtlantic/Northeast Visibility Union (MANE-VU) 2018 regional haze modeling.

This document synthesizes information from severa l documents that already describe parts of the process of preparing emissions estimates and pr ovides information not ye t included in other documents. It covers the following major steps in that process: preparat ion of the inter-Regional Planning Organization (RPO) Integr ated Planning Model® (IPM) runs commonly referred to as the Visibility Improvement State and Tribal As sociation of the Southe ast (VISTAS) IPM runs, the post-processing of those runs to create Sparse Matrix Operator Kernel Emissions (SMOKE) input files, the modification of those files to refl ect state estimates of emissions, and the adjustments made by MANE-VU modelers to maintain the Clean Air Interstate Rule (CAIR) cap. It also provides background information a bout preparing EGU forecasts and related work by the U.S. Environmental Protection Agency (EPA).

1.2 Background on Emissions Projections

Emission projections for point sources depend on changes in source level activity, the emission

factors or installed controls. Th e approach taken to project poin t source emissions depends on the level of detail necessary in the projection. Chan ges in point source emissions are accounted for by a combination of growth, control, and retiremen t rates. Growth rates are applied to estimate the overall change in activity, while retirement rates are applied to estimate the decrease in emissions activity from existing sources. Retirem ent (and replacement of these sources with new sources) must be considered be cause regulations affecting new sources may differ from those affecting existing sources.

The projection year control factor accounts fo r both changes in emission factors due to technology improvements and new levels of contro l required by regulations. The control factor accounts for three variables: regul ation control, rule effectiven ess, and rule penetration.

Control factors are closely linked to the type of emission process (identified by Source Classification Code (SCC)) and s econdarily to the type of i ndustry identified by Standard Industrial Classification (SIC). Point source projections should account for Federal, State, and local regulations affec ting these categories.

### 2 A complicating factor is the requirement for emission offsets in nonatt ainment areas through New Source Review requirements. This may be accounted for by 1) restricting growth under the assumption that it will be offset; 2) applying reduc tions to selected source categories to account for the emission growth which must be offset; or 3) selecting the indivi dual sources, based on a cost analysis, from which offsets are likely to come.

1.3 Factors Causing Variation in EGU Emissions Forecasts

There are various sources of uncertainty in esti mating future EGU emissi ons. These include the relative prices of various fuels (especially coal, oil, and natura l gas), predictions of which plants will be shut down, the size, type, and location of new plants, the total demand for electricity, and requirements imposed by state-specific or plant- specific regulations or orders. Emissions

estimates based on the methods described in th is report represent the MANE-VU states’ best

effort to forecast future emissions in light of these and other uncertainties.

When projecting Electricity Generating Unit (E GU) emissions in the Eastern United States, emission trading should be considered. There are three general appr oaches to performing projections while accounting for su ch trading schemes. The first option is to optimize control

levels across the domain based on the cost of alte rnative controls. The second option is to survey individual sources to determine how they will comply (will they apply controls and sell or buy allowances) and use this as the basis for the future year control level. The third option is to apply the control level used to establish the budget to all affected sources and ignore which sources may choose to buy or sell credits/allowances.

Other factors which must be c onsidered include programs, such as fuel switching, designed to provide source flexibility in meeting future air quality requirements. Fuel switching refers to

instances where a unit historica lly burned one primary fuel, such as coal, and under a "fuel switching" program the unit would burn an alternate fuel, such as natural gas, during a certain period of time and may switch back to the "historic" fuel for so me or all of the year. Fuel switching is often done in cases where sources aver age their emissions to meet federal mandates. Fuel switching may also be used as a seasonal compliance strate gy (e.g., switching from residual fuel oil to natural gas in order to reduce NOx em issions during the ozone season. The variation in emissions over the course of the year caused by fuels switching must be calculated properly in projections.

Repowering is another example of a planned change in emission rates which should be considered. In this case, the unit may be switchi ng entirely from coal to natural gas or may be completing a major modification whic h would lower the emission rate.

Spatial allocation is another factor which must be considered, particularly if air quality modeling will be performed using the projection. For poi nt sources, important questions are which facilities will retire and where new growth will occur. Changes in land use patterns may also impact the location of point source emissions. As undeveloped and rural areas become suburban and urban areas, the number of point s ources in that area will increase.

### 3 As can be seen from the discussion above, an y number of complicating issues can lead to emission forecasts which may differ from user to user. An inconsistent decision made between two parties can lead to significant differences in growth, control, or placement of emissions from point source forecasts. For this reason, the Re gional Planning Organizations (RPOs) in the

Eastern U.S. made a decision to utilize cons istent forecasting methods for EGU emissions, as they are one of the most significant contributor s to regional haze in the United States. This decision, to coordinate on the projection of EGU source emissions, led to the preparation of an

EGU forecast methods document from which a coordinated decision was made on methods to develop EGU emissions in future years. Each RPO ends up using somewhat different estimates, as discussed below, but there was a great deal of cooperation and data sharing throughout the

process.

### 4 2 PREPARATION OF EGU FORECASTS

2.1 Decision to Use the IPM Model

Early in the planning process there was a joint agreement by the RPOs to work together to develop future year EGU emissions estimates based on the use of the Integrated Planning

Model ® 

### (IPM). The decision to use IPM modeling resu lted in part from a study of EGU forecast methods prepared by E.H. Pechan and Associ ates, Inc. (Pechan) for the Midwest Regional Planning Organization (MRPO) (Pechan, 2004) , which recommended IPM as a viable methodology. Although IPM results were availabl e from work conducted by EPA to support their rulemaking for the Clean Air Interstate Ru le (CAIR), the RPOs c oncluded that certain model inputs needed to be revise d. Thus, the RPOs decided to work together to hire contractors to conduct new IPM modeling and to post-process th e IPM results. This section describes the

recommendation to use IPM.

The Lake Michigan Air Direct ors Consortium (LADCO) sought contractor assistance in reviewing emissions inventory growth for ex isting and new EGUs (Pechan, 2004). Because the

results of EGU emission forecasts are used in urban or regional scale air quality modeling exercises to estimate future year air pollutant concentrations, growth methods are needed to supply model-ready emission model inputs. The purpose of LADCO’s project was to begin to examine EGU growth methods.

The primary pollutants of intere st were sulfur dioxide (SO 2 

### ), oxides of nitrogen (NO

x 

### ), particulate matter (PM), ammonia (NH 3 

### ), and mercury (Hg). Projecti on years of interest included 2009 (the approximate time for ozone and PM 2.5 

### attainment) and 2018 (a longer term regional haze planning horizon). The geographic area of inte rest was the eastern half of the United States (to capture the trading issues affecting the Midwest States).

This 2004 Pechan report provided a detailed eval uation of three EGU growth modeling methods

of interest to the LADCO States for consid eration in developing its own approach. These evaluations addressed the following at tributes of each modeling approach:

• Description of primary an alytical modeling methods; • Geographic areas of application; • Advantages; and • Disadvantages.

The material in this evaluation was intended to be used to determine which of the currently available modeling approaches might be best suited for use by the LADCO States (and other RPOs) for future state implementation plan (SIP ) and air dispersion modeling work. The models evaluated in this report include d the Integrated Planning Model ® 

### (IPM), the National Energy Modeling System (NEMS), and the Elect ric Power Market Model (EPMM).

### 5 Based on the conclusions and summ ary of the report (P echan, 2004), the four participating RPOs (MANE-VU, MRPO, VISTAS, and the Central Re gional Air Planning Association, CENRAP) decided to use IPM as the tool for forecasting EGU emissions.

2.2 The Integrated Planning Model (IPM)

IPM was developed by ICF Consulting, Inc. (ICF) a nd used to support public and private sector clients. This model is a proprietary, multi-re gional, dynamic, deterministic linear programming model of the U.S. electric power se ctor. It provides forecasts of least-cost capaci ty expansion, electricity dispatch, and em ission control strategies for meeting energy demand and environmental, transmission, dispatc h, and reliability constr aints. It can be us ed to evaluate the cost and emissions impacts of propose d policies to limit emissions of SO 2 

### , NO

x 

### , carbon dioxide (CO 2 

### ), and Hg from the electric po wer sector. The IPM model was a key analytical tool used by EPA in developing the Clean Air Interstate Rule (CAIR) and the Clean Air Mercury Rule (CAMR).

Among the factors that make IPM particularly well suited to model multi-emissions control programs are (1) its ability to capture complex interactions among the electric power, fuel, and environmental markets; (2) its detail-rich representation of emi ssion control options encompassing a broad array of re trofit technologies along with emission reductions through fuel switching, changes in capacity mix and electricity dispatch strategies; a nd (3) its capability to model a variety of environmental market mech anisms, such as emissions caps, allowances, trading, and banking. The model’s ability to capt ure the dynamics of th e allowance market and its provision of a wide range of emissions reduction options ar e particularly important for assessing the impact of multi-emissions e nvironmental policies like CAIR and CAMR.

2.3 U.S. EPA Use of IPM

The U.S. EPA uses IPM to analyze the projected im pact of environmental policies on the electric power sector in the 48 contiguous states and the District of Colu mbia. The next two sections describe EPA modeling results available to the RPOs early in the planning process. Then

Section 2.3.3 reviews the limitati ons of the EPA results that led the RPOs to conduct additional IPM modeling.

2.3.1 EPA’s Base Case 2004

The EPA’s Base Case 2004 (EPA, 2005a) served as the starting point against which EPA compared various policy scenarios. It is a projection of electricity sector activity that takes into

account federal and state air emissi on laws and regulations whose provi sions were either in effect or enacted and clearly delineated at the time the base case was finalized in August 2004. Regulations mandated under the Clean Air Ac t Amendments of 1990 (CAAA), but whose provisions have not yet been finalize d, were not included in the base case . These include:

• Measures to Implement Ozone and Particulate Matter (PM) Standards : EPA Base Case 2004 predates and so does not include the pr ovisions of CAIR, the primary federal regulatory measure for achieving the National Ambient Air Quality Standards (NAAQS)

### 6 for ozone (8-hour standard of 0.08 ppm) and fine particles (24-hour average of 65 ug/m3 or less and annual mean of 15 ug/m3 for par ticles of diameter 2.5 micrometers or less, i.e., PM 2.5 

### ). EPA Base Case 2004 was used to evaluate policy alternatives which ultimately resulted in CAIR. The final CA IR was issued on March 10, 2005. EPA Base Case 2004 includes measures to implement ozone and particulate matte r standards to the extent that some of the state regulati ons included in EPA Base Case 2004 contain measures to bring non-attainment areas into attainment. Individual permits issued by states in response to ozone and particulate ma tter standards are not captured in the base

case.

• Mercury Regulations on Elect ric Steam Generating Units: EPA Base Case 2004 predates both CAMR, which was issued by EPA on March 15, 2005 and the “Maximum Achievable Control Technology” (MACT) st andards that were scheduled to be promulgated by December 15, 2004, but, pending litigation, were superseded by CAMR. Consequently, this base case did not include any federal regulatory measures for mercury control. (CAMR was vacated in 2008.)

• Clean Air Visibility Rules: On July 1, 1999, EPA issued Regional Haze Regulations to meet the national goal for visibility establ ished in Section 169A of the CAAA, which calls for “prevention of any future, and the remedying of any existing, impairment of visibility in Class I areas [156 national parks and wilderne ss areas], which impairment results from manmade air pollu tion.” The regulations required states to submit revised SIPs that (1) establish goals that provi de for reasonable progr ess towards achieving natural visibility conditions at Class I areas , (2) adopt a long-term control strategy that includes such measures as are necessary to achieve the reasonable progress goals, and (3) require Best Available Retrofit Technology (BART) for sources in listed source categories placed in operation between 1962 and 1977.

In effect, EPA Base Case 2004 offered a snapshot projection of the electric sector assuming that the only future environmental regulations were those with provisions known at the time that the base case assumptions were finalized. While not n ecessarily an accurate re flection of what would actually occur, this assumption ensured that th e base case was policy neutral with respect to future environmental policies.

2.3.2 EPA CAIR Case

On January 30, 2004, EPA proposed CAIR, which set emission reduction requirements for 29

States and the District of Columbia. Those emission reduction requirements were based on achieving highly cost-effective em ission reductions from large el ectricity generating units.

While EPA believed that the modeling it init ially performed for the January 2004 proposal provided a reasonable estimate of the impact of requiring highly cost-effective emission reductions from electricity generati ng units, it did not exactly m odel the proposed control region.

For both SO 2 

### and NO

x 

### , EPA used modeling assumptions that differed slightly from the January 2004 CAIR proposal. For SO 2 

### in particular, EPA modeled th e program assuming a cap on

national emissions rather than in the 29 St ates proposed. Although EPA believed the modeling

### 7 done at that time provided a reasonable approxim ation of the impacts of the original CAIR, because 92 percent of the SO 2 

### emissions in the 48 contiguous Stat es occur in the 28 States that were covered by the proposal, EPA completed additional analysis. This additional analysis examined the effect of covering the geographi c region proposed in the January 30, 2004 proposal using the NO

x 

### emissions cap and a close approximation of the SO 2 

### cap proposed for CAIR (EPA, 2005a).

For the supplemental proposal, EPA performed refined modeling of the emission reduction requirements proposed on January 30, 2004. In this refined modeling, EPA modeled the exact control regions for both SO 2 

### and NO

x 

### , as proposed.

2.3.3 EPA’s CAIR Modeling Limitations

The U.S. EPA’s modeling was based on its best judgment for various input assumptions that were uncertain, particularly assu mptions for future fuel prices and electricity demand growth (EPA, 2004). In addition, EPA’s modeling using IPM did not take into account the potential for advancements in the capabilities of pollution control technologies for SO 2 

### and NO

x 

### removal as

well as reductions in their costs over time.

Retirement Ratios: EPA issued a CAIR supplemental notice of proposed rulemaking that proposed two alterna tives for how the SO 2 

### reduction target would be achieved. The proposal took comment on implementing the reduction requirements in the second phase either by using a 2.86 to 1 ratio (which would match the 65 percent SO 2 

### reduction target) of acid rain allowances to emissions, or alternatively, by implementing the reductions using a 3 to 1 ratio (for administrative simplicity) and then letting States create and distribute additional allowances equal to the surplus created by the 3 to 1 ratio to achieve the proposed 65 percent reduction. In either case, the effective cap on SO 2 

### emissions from the power se ctor would be the same.

Modelers assumed a 3 to 1 Title IV allowance retirement ratio for 2015 and beyond to implement the reductions in the proposed control region. The model did not add back the 130,000 tons of

SO 2 

### from over-compliance that would result from this ratio. Therefore, in this modeling, EPA analyzed slightly greater SO 2 

### emission reductions th an required by the pr oposal. This assumption was made for modeling simplicity and was expected to result in a slight overestimate of costs for the proposal and of the emissions reductions achieved.

BART: The EPA did not incorporate any best ach ievable retrofit technology (BART) modeling in this analysis. BART would achieve reduction s in non-CAIR States and had the potential to mitigate leakage issues.

Demand Response: EPA’s 2004 CAIR case includes a dema nd response to incr eased natural gas prices but not electricity prices. In the model, increased gas pr ices would prompt the public to curtail their use of gas and en courage them to seek substitutes. However, no provision for demand response was included for electricity prices. If demand had been allowed to change in response to increasing prices of electricity, one can assume that consumers would have reduced their demand for electricity, lowering electricity prices and reducing gene ration and emissions to

some extent.

### 8 State Rules: Only some State-adopted rules were inco rporated into EPA’s modeling framework.

A list of the State Mul ti-pollutant regulations used in IPM 2.1, IPM 2.1.6, and IPM 2.1.9 can be located in Appendix 3-2 of EPA’s Standalone Documentation for EPA Base Case 2004 (v.2.1.9) Using the Integrated Planning Model (EPA, 2005a).

Because of the limitations noted above, the RPOs decided to initiate their own IPM modeling based on the EPA’s latest update of the IPM input framework, called IPM 2.1.9. EPA completed the input framework for IPM 2.1.9 in March of 2003.

2.4 RPO Use of IPM – Phase I

In August 2004, VISTAS contracted with ICF to r un IPM to provide revised utility forecasts for

2009 and 2018 under two future scenarios – Base Case and CAIR Case (ICF, 2004). The Base Case represented the current operation of the pow er system under laws and regulations as known at the time the run was made, including those that come into force in the study horizon. The CAIR Case was the Base Case with the proposed CAIR rule superimposed. Run results were parsed at the unit level for the 2009 and 2018 run years. 1



### In August 2004, MRPO contracted with Pechan to post-process the VISTAS’ IPM outputs to provide the (National Emission I nventory Input Format) NIF forma tted emission files needed for the regional inventory. The IPM ou tput files were delivered by ICF to VISTAS in November 2004 and the post-processed data files were de livered by Pechan to the MRPO in December

2004.

These IPM runs (VISTAS_CAIR_2) and the NIF files that were generated from the parsed data sets are commonly referred to as the Phase I In ter-RPO runs. The Phase I runs were ultimately not used in RPO modeling of regi onal haze, as further revisions to the inputs were necessary once the final version of CAIR was adopted.

2.5 RPO Use of IPM – Phase II

On March 10, 2005, EPA issued the final CAIR . A consortium of RPOs, (MANE-VU, VISTAS, MRPO, and CENRAP) conducted a nother round of IPM modeling which reflected changes to control assumptions based on the final CAIR as well as additional changes to model inputs based on state and local agency and stakeholder commen ts. Several conference ca lls were conducted in the spring of 2005 among the participating RP Os to discuss and provide comments on IPM assumptions related to six main topics: power system operation, generating resources, emission control technologies, set-up parameters, financia l assumptions, and fuel assumptions. Based on these discussions, VISTAS sponsored a new se t of IPM runs to reflect the final CAIR

1 “Parsing” results refers to allocating emissions estimates to individual units. Results may be analyzed in aggregate form but must be parsed in order to be used in air quality modeling. (See Section 3.2)

### 9 requirements as well as certain changes to IPM assu mptions that were agreed to by the RPOs. ICF performed the following four runs using IP M during the summer of 2005. This set of IPM

runs is referred to as the VISTAS Phase II analysis or Inter-RPO v.2.1.9 runs.

 Base Case with EPA 2.1.9 coal, gas, and oil price assumptions (VISTASII_BC_1Z1).

 Base Case with EPA 2.1.9 coal and gas supp ly curves adjusted for the U.S. Energy

Information Administration’s most recent Annual Energy Outlook (AEO 2005) reference case price and volume relati onships (VISTASII_BC_2Y).

 Strategy Case with EPA 2.1.9 coal, gas and oi l price assumptions (VISTASII_PC_1f).

 Strategy Case with EPA 2.1.9 coal and ga s supply curves adjusted for AEO 2005 reference case price and volume relationships (VISTASII_PC_2C).

The above runs were parsed for 2009 and 2018 r un years. The output taken from the Strategy Case with EPA 2.1.9 coal, gas, and oil price assu mptions (VISTASII_PC_1f) is also referred to

as the Inter-RPO CAIR Case IPM 2.1.9 or RPO 2.1.9 IPM and is the basis for discussion in the remainder of this report. That run was also parsed for 2012. The RP O 2.1.9 IPM parsed results were post-processed for 2009, 2012, 2018, as described in Section 3.2.1

The Phase II scenarios were based on VISTAS Phase I and EPA IPM 2.1.9 assumptions (EPA, 2005b). Additional changes that were implemented in the above four runs are summarized below and in associated documentation (ICF, 2007):

 Unadjusted AEO 2005 electric ity demand projections were used. (U.S. EPA runs were adjusted to reflect reduced demand due to vol untary conservation projects sponsored by U.S. EPA)

 Gas supply curves were adjusted for AEO 2005 reference case price and volume relationships. The EPA 2.1.9 gas supply curves were scaled such that IPM solved for AEO 2005 gas prices when the power sector ga s demand in IPM is consistent with AEO 2005 power sector gas demand projections.

 The coal supply curves used in EPA 2.1.9 were scaled such that the average mine mouth coal prices that the IPM was solving in aggr egated coal supply regions were comparable to AEO 2005. Coal grades and supply re gions contained in AEO 2005 and EPA 2.1.9 were not directly comparable. An iterative approach was used to obtain comparable results. The coal transportation matrix was not updated with Energy Information Administration (EIA) assumptions due to significant differences between the EPA 2.1.9 and EIA AEO 2005 coal supply and coal demand region configurations.

 The cost and performance of new units we re updated to AEO 2005 reference case levels.

 The run years 2008, 2009, 2012, 2015, 2018, 2020 and 2026 were modeled.

 The AEO 2005 life extension costs for foss il and nuclear units were incorporated.

 The extensive NEEDS comments provided by VISTAS, MRPO, CENRAP and MANEVU were incorporated into the Phase I NEEDS input file.

 MANE-VU’s comments in regards to the north east state regulations were incorporated.

 Northeast Renewable Portfolio Standards (RPS) were modeled based on the Regional Greenhouse Gas Initiative analys is. A single RPS cap was modeled for MA, RI, NY, NJ, MD, and CT. These states could buy credits from NY or from the PJM Interconnection and New England model regions.

### 10  Selective Catalytic Reduction (SCR) and Sc rubber Feasibility Limits: No limits were applied in 2008, 2009 and 2010 to the capacity for installing these emissions controls.

 The Clean Air Visibility Rule (CAVR) was not modeled.

 Modelers assumed a Title IV SO 2 

### Bank for 2007 of 4.98 million tons.

 The investments required under the Illinois Power, Mirant and First Energy NSR settlements (as identified during spring 2005) were incorporated in the above runs.

For the Phase II inter-RPO set of IPM runs, ICF generated two different parsed files for each of the two strategy case scenarios (VISTAS II_PC_1f and VISTAS II_PC_2c). One file includes all fuel burning units (fossil, biomass, landfill gas) as well as non-fuel burning units (hydro, wind, etc.). The second file contains just the fossil- fuel burning units (e.g., emissions from biomass and landfill gas are omitted). In all RPOs the fossil- only file was used for modeling. This is consistent with EPA, since EPA used the fossil only results for CAIR analyses.

### 12 3 POST PROCESSING OF IPM OUTPUT

3.1 Use of SMOKE Emissions Processing Model

On behalf of MANE-VU, modelers from Th e Northeast States for Coordinated Air Use Management (NESCAUM) used an emissions pro cessing model to prepar e data produced by the IPM model for use in air quality and visibility modeli ng. The Sparse Matrix Operator Kernel Emissions (SMOKE) Modeling System is an em issions processing system designed to create gridded, speciated, hourly emissions for input into a variety of air quality models, such as EPA’s Community Multi-Scale Air Quality (CMAQ) model and Regional Modeling System for Aerosols and Deposition (REMSAD) (Houyoux, et. al., 2000). SMOKE supports area, biogenic, mobile (both onroad and nonroad), and point source emissions processing for criteria, particulate, and toxic pollutants. For biogeni c emissions modeling, SMOKE uses the Biogenic Emission Inventory System, version 2.3 (BEIS2) and version 3.09 and 3.12 (BEIS3). SMOKE is also integrated with the onr oad emissions model MOBILE6.

The sparse matrix approach used throughout SMOKE permits rapid and flexible processing of emissions data. Flexible processing comes fr om splitting the processing steps of inventory growth, controls, chemical speciation, tempor al allocation, and spa tial allocation into independent steps whenever possible. The results from these steps are merged together in the final stage of processing using vector-matrix mu ltiplication. It allows in dividual steps (such as adding a new control strategy, or processing for a different grid) to be performed and merged without having to redo all of the other processi ng steps. Individual emission scenarios were simulated for MANE-VU using the SMOKE Modeling System.

NESCAUM, on behalf of MANE-VU and its particip ating States, conducted regional air quality simulations for calendar year 2002 and several future periods (NESCAUM, 2008). This work was directed at satisfying a number of goals u nder the Haze State Implem entation Plan (SIP), including a contribution assessment, a polluti on apportionment for 2018, and the evaluation of visibility benefits of control measures being considered for achieving reasonable progress goals and establishing a long-term emissions manageme nt strategy for MANE-VU Class I areas. The modeling tools utilized for these analyses in clude the Fifth-Genera tion NCAR / Penn State

Mesoscale Model ( 

### MM5), SMOKE, CMAQ and REMSAD, and in corporate tagging features that allow for the tracking of individua l source regions or measures. These tools have been evaluated and found to perform adequately relati ve to U.S. EPA modeling guidance.

As described below, in order for NESCAUM to process the EGU emissions generated by the

IPM ® 

### procedures noted above, a series of intermedia te steps were required to get the activity and emission data into the appropria te format for SMOKE processing.

3.2 Preparing IPM Output for Use in SMOKE Model

IPM can produce projections at the regional, state, pl ant, or unit level. Data must be parsed to provide the unit level information required for chemical transport modeling. Parsing involves developing detailed unit level info rmation from the model’s projecti ons at the model plant level. ICF parsed the VISTASII_PC_1f data for use by the RPOs.

### 13 Further post-processing of IPM parsed output is needed to prepare the files for use by the SMOKE emissions processing model. The following sections describe the intermediate steps necessary to make these conversions. The first st ep is the augmentation of the IPM parsed output files to include additional unit level characteristics and pollutant estimates necessary for one atmosphere modeling. This step converts the IPM parsed data files into EPA’s National Emission Inventory Input Format (NIF). The second step is the additiona l conversion of these NIF files into the Inventory Data Analy zer (IDA) format required by th e SMOKE emissions processor.

3.2.1 IPM to NIF

After running IPM, ICF provided an initial spreadsheet file cont aining unit-level records for

both: (1) “existing” units (those currently in ope ration during the modele d base year) and (2) committed/planned or new generic aggregat es (new generic units expected to come

online or identified as needed to meet el ectric generation dema nd in a geographic area).

IPM parsed file reco rds include unit and fuel type data; existing, re trofit (for SO 2 

### and NO

x 

### ), and separate NO

x 

### control information; annual SO 2 

### and NO

x 

### emissions and heat input; summer season (May-September) NO

x 

### and heat input; July day NO

x 

### and heat input; coal heat input by coal type; nameplate capacity megawatt (MW), and State FI PS codes (Federal Information Processing codes used to identify geographic areas). Exis ting units also had county FIPS codes, a unique plant identifier (ORISPL) and unit ID (also called boiler ID) (BLRID); gene ric units did not have

these data.

The processing of IPM parsed data to NIF format included estimating emissions of pollutants not generated by IPM and adding control efficien cies, stack parameters, latitude-longitude coordinates, and State identifiers (plant ID, point ID, stack ID, process ID) from a series of lookup tables or by matching to individual units as configured in base y ear 2002 emission files (Pechan, 2005). Additionally, new generic units created by IPM were sited in a county and given appropriate IDs. This processing is described in more detail below.

Generic Units : The new generic units and associated data were prepared by transforming the generic aggregates into units similar in size and fuel to existing units in terms of the available data. Generic aggregates were split into sma ller generic units based on their unit types and capacity. Each generic unit was provided a dummy ORIS unique plant and boiler ID, and was given a county FIPS code based on an algorithm that sited each gene ric unit by assigning a sister plant that is in a county based on its attainment/nonattainment status. Within a State, existing plants (in county then ORIS plant co de order) in attainment counties were used first as sister sites to new generic units (to obt ain county location), followed by existing plants in PM nonattainment counties, followed by existing plants in 8-hour ozone nonattainment counties. No States identified counties that should not be considered when siting new generic units, so this process was identical to the one used for EPA IPM post-processing under CAIR.

### 14 SCCs were assigned to existing units using unit/fuel/firing/bottom t ype data. SCCs were assigned to generic units using unit and fuel type information. Latitude-longitude coordinates were assigned, first using the EP A-provided data files, secondly using an in-house contractor developed latitude-longitude file, and lastly using county cent roids. These addi tional location files were only used when the da ta were not provided in the original 2002 base year files. Stack parameters were then assigned to each unit, first using the EPA- provided data files, secondly using an in-house stack pa rameter file based on previous EI A-767 data, and las tly using an EPA June 2003 SCC-based default stack parameter file . These data were only used when the data were not provided in th e 2002 base year files.

IPM does not calculate emissions for all pollu tants necessary for regional haze modeling. Therefore additional data were required to estimate VOC, CO, filterable primary PM 10 

### and

PM 2.5 

### , PM condensable, and NH 3 

### emissions. Thus, ash and sulfur contents were assigned by first using 2002 EIA-767 values for existing units or SCC-based defaults; filterable PM 10 

### and PM 2.5 

### efficiencies were obtained from the 2002 EGU NEI that were based on 2002 EIA-767 control data and the PM Calculator pr ogram (a default of 99.2 percen t is used for coal units if necessary); fuel use was back calculated from th e given heat input and a default SCC-based heat content; and emission factors were obtained from an EPA-approved emission factor file based on AP-42 emission factors. Table 2 presents th e SCC-based default heat content and stack parameters used when actual data were not av ailable. Table 3 (worksheet sccemfac100704 from MRPOpostprocdatafiles.xls, Pech an 2005) reflects emission fact ors used to develop emission estimates of CO, VOC, filterable PM, and NH 3

### Condensable PM : To estimate total primary PM emissions, additional calculations were

conducted to derive condensable PM emissions from these sour ces. In MANE VU and VISTAS

PM condensable emissions were calculated base d on factors derived from AP-42 defaults. In

MRPO no condensable emissions were estimated or included in the inventory. (Janssen, 2008) Table 4 (worksheet pmcdef fr om MRPOpostprocdatafiles.xls, Pechan 2005) shows these PM condensable emission factors and SCC assignments.

### Additional Pollutants : As noted above, in pr ocessing IPM parsed data to convert it to NIF format, emissions of additional pollutants were estimated. Emissions for 28 temporal-pollutant combinations were estimated since there are seven pollutants (VOC, CO, primary PM 10 

### and

PM 2.5 

### , NH 3 

### , SO 2 

### and NO

x 

### ) and four temporal periods (ann ual, summer season, winter season, and July day).

Crosswalk Match to 2002 Inventory : The final step in the IPM to NIF conversion process was to

match the IPM unit IDs with the identifiers in the base year 2002 inventory for existing EGUs. A

crosswalk file was used to obt ain FIPS State and county, plant ID (within State and county), and point ID. If the FIPS State and county, plant ID and point ID were in the 2002 base year NIF tables, then the process ID and stack ID were obtained from the NIF; otherwise, defaults, described above, were used.

The post-processed files were then provided in NIF 3.0 format. Two sets of tables were developed : “NIF files” for IPM units that had a crosswalk match and were in the 2002 base year inventory, and “NoNIF files” for IPM units that were not in the 2002 base year inventory (which included existing units with or w ithout a crosswalk match as well as generic units). Two special cases relating to the crosswalk match were handled as follows:

1. One-to-many match: At a given plant, if one IPM boiler ID was matched to more than one point ID, the boiler data were put on the first point ID records; records from the other point IDs were delete d from the relevant tables.

2. Many-to-one match: At a given plant, if more than one IPM boiler ID was matched to one point ID, all the boilers’ emissions (tons), throughput (really heat input in MMBtu), and capacity (MW) were summed (“summed boiler”) and put on that point

### 18ID’s records in the relevant tables. The values for stack parameters and latitudelongitude values were those from the first record summed.

3.3 State Results – Phase II Augmented

Summarizing the results of the estimation of additional pollutants, Table 5 presents additional pollutant augmented State level emission results from the 2018 Inter-RPO CAIR Case IPM v. 2.1.9 fossil-only parsed file (VIS TASII_PC_1f with pollutant a ugmentation; found in modeling

file ida_egu_18_basef_2453605.txt from VISTAS BaseF). A co mparison of RPO totals for SO 2 

### and NO

x 

### shows that these are the same as presented in Table 1.

3.4 NIF to IDA

The main purpose of the SMOKE conversion task was to convert EGU emission inventories provided in NIF format into the IDA format required by the SMOKE model for the criteria pollutants VOC, NO

x 

### , CO, SO 2 

### , PM 10 

### , PM 2.5 

### , and NH 3 

### . Annual and seasonal emissions were taken directly from the NIF structured invent ories with no alternate temporal calculations performed (e.g., estimate seasonal emissions from annual or annual from seasonal). The temporal allocation module of the SMOKE emissions processor was intended to be us ed to further define temporal distribution of these emissions.

No quality assurance (QA) related to the reporte d values in the NIF files was conducted (e.g., it was assumed that reported emission levels were correct) and therefore the QA focus was to maintain the integrity of the mass files in the conversion to IDA.

Each set of NIF structured data had a unique set of relational tables necessary to maintain the information required in each source sector based on its reporting requirements. Conversion scripts to read the information from each of thes e relational data sets and convert them to the IDA structures required by this task were impl emented by Alpine (Alpine, 2006). Prior to and after the conversion from NIF to IDA, a list of emission summary repor ts was developed to check that the emissions input in to the conversion process were th e same as output into the IDA

formatted files.

### 20 4 MODIFICATIONS BY OTHER REGIONS

4.1 Emission Control Modifications wi thin VISTAS, MRPO, and CENRAP

State and local agencies and invited stakeholde rs from VISTAS, MRPO, and CENRAP reviewed

the results of the Inter-RPO Phase II set of IPM runs. These stakeholders primarily reviewed and

commented on the IPM results with respect to IPM decisions on NO

x 

### post-combustion controls

and SO 2 

### scrubbers and provided additional information on when and where new SO 2 

### and NO

x 

### controls were planned to come online based on the best available data from state rules, enforcement agreements, compliance plans, permits, and discussions/commitments from individual companies. They also reviewed th e IPM results to verify that known and existing

controls and emission rates we re properly reflected in the IPM runs. After considering comments, those RPOs adjusted the IPM results for specific units using new information they had as part of the permitting process or other co ntact with the industry th at indicated which units

would install controls as a re sult of CAIR and when these new controls would come on-line (MACTEC, 2007; MRPO 2006; ENVIRON 2007).

As described in the following section, some entities specified changes to the controls assigned by

IPM to reflect their best estimates of emission control levels. These changes typically involved either 1) adding selective cataly tic reduction (SCR) or scrubber controls to units where IPM did not predict SCR or scrubber controls, or 2) re moving IPM-assigned SCR or scrubber controls at units where the commenting entity indicated there we re no firm plans for controls at those units.

At this point in the process MANE-VU decided not to make any changes to the northeastern state IPM output regardless of state knowledge of di screpancies with actual conditions. MANE-VU determined that IPM provided a reasonable estima te of the impact of the CAIR cap and trade program consistent with methods used by EPA, and planners were concerned that adjustments

would not reflect the allocation of all allowed emissions under CAIR.

In MANE-VU’s final modeling, many of the cha nges made by the other RPOs were included, but due to the timing of the release of revised data, the location with respect to the modeling domain, and need to progress with modeling, M ANE-VU did not incorpor ate changes reflected

in the final CENRAP EGU files.

4.2 Emission Factor and Control Modifica tions for VISTAS Emission Sources

VISTAS reviewed the PM and NH 3 

### emissions from its States’ EGUs provided after the original

IPM to NIF conversation conducted for the RPOs a nd identified significantly higher emissions in

2009/2018 than in 2002. VISTAS determined th is conversion used a set of PM and NH 3 

### emission factors that were “the most recent EPA approved uncontrolled emission factors” for estimating 2009/2018 EGU emissions but were most likely not the same emission factors used by States for estimating these emissions in 2002. Thus, the emission increase from 2002 to 2009/2018 was simply an artifact of the change in emission factors, not anything to do with changes in activity or control technology applic ation. During this review, VISTAS additionally

identified an inconsistent use of SCCs for de termining emission factors between the base and future years.

### 21 Documentation (Alpine, 2005a, b) indicates that VISTAS adjusted the 2002 base year emissions inventory to account for these discrepancies in base year and future year PM and NH 3 

### emission factor use. Using the latest “EPA-approved” uncontrolled emission f actors by SCC, Alpine

utilized data collected under EPA’s Consolidat ed Emissions Reporting Rule (CERR) or data reported by VISTAS. Alpine us ed reported annual heat input, fuel throughput, heat, ash, and

sulfur content to estimate annual uncontrolled 2002 emissions for units identified as having corresponding output from IPM. This step wa s conducted for non-CEM pollutants (CO, VOC, PM, and NH 3 

### ) only. For PM emissions, the condensable component of emissions was calculated and added to the resulting PM primary estima tions. The resulting 2002 emissions were then adjusted by any control efficiency factors repo rted in the CERR or VISTAS data collection effort. The second adjustment was to the future y ear inventories. Alpine updated the SCCs in the future year inventory to assign the same SCC used in the base year. Using the same methods as described for the 2002 revisions, those non-IPM generated pollutants were estimated using IPM predicted fuel characteristics a nd base year 2002 SCC assignments.

In addition to the changes to the emission factor assignments, SCC, and IPM-assigned controls, VISTAS also specified other ch anges to the IPM re sults or converted IPM to NIF files. Comments on changes in stack parameters from the 2002 inventory were implemented in the converted files for the 2018 inventory. Changes to stack parameters were also made in cases

where new controls were scheduled to be in stalled. In cases where an emission unit was projected to have an SO 2 

### scrubber by 2018, some Stat es were able to pr ovide revised stack parameters for some units based on design f eatures for the new control system. Other units projected to install sc rubbers by 2018 were not far enough along in the design process to have specific design details. For those units, VIST AS made the following assumptions: 1) the scrubber is a wet scrubber; 2) ke ep the current stack he ight the same; 3) keep the current flow rate the same, and 4) change the stack exit temperature to 169 degrees F (this is the virtual temperature derived from a wet temperatur e of 130 degrees F) (M ACTEC, 2007). VISTAS determined that exit temperatur e (wet) of 130 degrees F +/- 5 degrees F is representative of

different size units and wet scrubber technology.

4.3 Emission Inventory Replacement by Western States

During the development of their EGU emission fo recast, the Western Regional Air Partnership (WRAP) conducted an exercise where IPM was not used to pr epare emission estimates from EGU sources. Using capacity factor adjustme nts and emission control assumptions, WRAP developed a forecast of EGU emissions based on its initial 2002 base year inventory (ERG, 2006). This revised forecast was used by some of the other RPOs and replaced the emissions generated for the domain by IPM. This change by WRAP is reflected in the difference in State

emission totals between Tables 5 and 6. As WRAP is outside the MANE VU modeling domain, this change was not reflected in MANE-VU modeling. MANE-VU did not change its boundary conditions to reflect this change.

4.4 Eliminating Double Counting of EGU Units

An additional set of procedures was used by MANE-VU and VISTAS to avoid double counting of EGU emissions in the 2018 point sour ce inventory (MACTEC, 2006, 2007). Since each

### 22 RPO’s 2002 emissions inventory file containe d both EGUs and non-EGU point sources, and EGU emissions were projected using IPM, it was necessary to split the 2002 point source file into two components. The first component contai ned those emission units accounted for in the IPM forecasts. The second component contained al l other point sources not accounted for in

IPM.

As described in the previous section, 2018 NIF files for EGUs were prepared from the IPM parsed files. All IPM matched units were initially removed from the 2018 point source inventory to create the non-EGU inventory (which wa s projected to 2018 using non-EGU growth and control factors). This was done on a unit-by-unit basis based on a cross-reference table that matched IPM emission unit identifiers (ORISPL plant code and BLRID emission unit code) to NIF emission unit identifiers (FIPSST state code , FIPSCNTY county code, State Plant ID, State Point ID). When there was a match between th e IPM ORISPL/BLRID a nd the emission unit ID, the unit was assigned to the EGU inventory; al l other emission units were assigned to the nonEGU inventory.

If an emission unit was contained in the NIF files created from the IPM output, the corresponding unit was removed from the initia l 2018 point source inventory. For VISTAS, the NIF 2018 EGU files from the IPM parsed files were then merged with the non-EGU 2018 files to create a complete 2018 point source scenario.

Next, several ad-hoc QA/QC queries were done to verify that there was no double-counting of

emissions in the EGU a nd non-EGU inventories:

 The IPM parsed files were reviewed to identif y EGUs accounted for in IPM. This list of emission units was compared to the non-EGU inventory derived from the IPM-NIF crossreference table to verify that units account ed for in IPM were not double-counted in the non-EGU inventory. As a result of this compar ison, a few adjustments were made in the

cross-reference table to add emission units fo r plants to ensure these units accounted for in IPM were moved to the EGU inventory.

 The non-EGU inventory was further reviewed to identify remaining emission units with

an Standard Industrial Classi fication (SIC) code of “4911 El ectrical Services” or Source

Classification Code of “1-01-xxx-xx External Combustion Boiler, Electric Generation”. The list of sources meeting thes e selection criteria were compar ed to the IPM parsed file

to ensure that these units were not double-counted.

 VISTAS invited various stakeh older groups to review the 20 18 point source inventory to verify whether there was any double counting of EGU emissions. In some instances, corrections were provided where an emission unit was double counted.

### 24 4.6 Revised Results – VISTAS Base G2 Adjustment

VISTAS further refined their future predicti ons based on further state input. The resulting modeling file was called the Base G2 inventory. Table 7 presents State level emission results

from the Base G2 2018 Inter-RPO CAIR Case IP M v. 2.1.9 parsed file modified by VISTAS.

Some states specified changes to the controls as signed by IPM to reflect their best estimates of emission control levels. These changes typically involved either 1) addi ng selective catalytic reduction (SCR) or scrubber controls to units where IPM did not predict SCR or scrubber controls, or 2) removing IPM-as signed SCR or scrubber controls at units where the commenting entity indicated their were no firm plans for cont rols at those units. These changes were based

on those states’ best available information a bout where and when emissions controls were expected to be installed, as well as informati on concerning IPM-predicte d plant closures that were deemed unlikely to occur. In comparing Table 7 with Table 6, it can be seen that the changes included in the Base G2 i nventory were requested by the st ates of Florida, Georgia, and

North Carolina.

Note that no changes were made at this time by the MANE-VU states. The net effect of these changes was to reduce emissions of SO 2 

### relative to either Table 5 or Table 6.

### 26 5 ADDITIONAL ADJUSTMENTS BY NORTHE ASTERN STATES AND MODELERS

FOR REGIONAL HAZE SIP MODELING

5.1 Introduction

MANE VU used the G2 inventory as the basis for further adjustments to incorporate MANE-VU state changes and also to represent the MANE VU control strategy for key EGUs. These modifications resulted in a) SO 2 

### emissions reductions at one M ANE-VU EGU source subject to

Best Available Retrofit Technol ogy (BART) requirements, 2) em issions increases in MANE-VU

to reflect states’ best estimates that some sour ces predicted by IPM to be closed would continue to operate and information about where and wh en emission controls would or would not be installed, 3) SO 2 

### emissions reductions at key EGUs (or alternative faciliti es) to reflect the MANE-VU EGU strategy, and 4) increases in SO 2 

### emissions to estimate the predicted effect of emissions trading under the CAIR program. Each of these is explained below.

5.2 Best Available Retrofit Technology (BART)

To assess the impacts of the implementation of the BART provisions of the Regional Haze Rule, NESCAUM included estimated reductions anticip ated for BART-eligible facilities not covered by CAIR in the MANE-VU region in the 2018 CMAQ modeling analysis. A survey of state staff indicated that eigh t units would likely be controlled under BART alone. State-provided potential control technologies and levels of control for these sources we re incorporated into the 2018 emission inventory projections used in MANE-VU’s March 2008 modeling run (NESCAUM, 2008b). The eight BART-eligible units included one EGU point source, which is located in Maine (Wyman Station).

5.3 MANE-VU State Modifica tions of IPM Results

Previously, during development of the Base G a nd Base G2 inventories, MANE-VU states had relied on the RPO IPM model results (Base F) without revisions. In 2007, the MANE-VU states decided that they should revise the estimates, as other RPOs had done, to reflect their best estimates of future source operations and controls . State and regional staff reviewed and revised the IPM results with respect to when and where new SO 2 

### controls were planne d to come online. Modifications were based on state rules, enforcement agreements, compliance plans, permits, and commitments from individual companies. St ates reviewed the IPM results to verify that known and existing controls and emission rates were properly reflected in the IPM results. In addition, states noted that some units predicte d by IPM to close were very unlikely to cease operation.

The net effect of these adjustments was an increase in SO 2 

### emissions in the MANE-VU region as

a whole. In Delaware SO 2 

### emissions decreased due to controls on a major source. Emissions in Connecticut, the District of Columbia, Rhode Island, and Vermont remained the same as predicted by RPO IPM 2.1.9 (B ase F). Emissions of SO 2 

### in other MANE-VU states increased. No changes were made in emissions of other pollutants.

### 27 5.4 MANE-VU EGU Strategy

MANE-VU states have recognized that SO 2 

### emissions from power plants are the single largest contributing sector to visibility impairment in the Northeast’s Class I areas. Sulfate formed through atmospheric processes from SO 2 

### emissions are responsible for over half the mass and approximately 70-80 percent of the extinction on the worst visibility days (NESCAUM, 2006a, and b). The emissions from power plants dominate the SO 2 

### inventory.

A modeling analysis was conducted to identify those EGUs with the greatest impact on visibility in MANE-VU. As part of the MANE VU Contribution Assessment, two MANE-VU modeling centers undertook CALPUFF modeling to identify the top 100 stacks that impacted three of the

MANE VU Class I areas in the ba se year, 2002. These three ar eas are Acadia, Brigantine and Lye Brook. Details of the modeling are pr ovided in Appendix D of the Contribution Assessment. (NESCAUM, 2006a) Appendix D of the Contribution Assessment includes a model performance evaluation, including compar isons of CALPUFF results from two different modeling groups using different me teorological drivers, as well as comparisons to other models

and to ambient data. The overall CALPUFF results were similar and performance was acceptable.

The CALPUFF modeling results were sorted to identify the indivi dual stacks causing the highest

24-hr concentrations at each of the three Class I areas. Impacts were not summed for all stacks at a facility. The 100 top stacks for each Cla ss I area are listed in Tables 10 and 20 from Appendix D “Dispersion Model Technique s” of the Contribution Assessment.

The two modeling centers us ed 2002 U.S. EPA Continuous Emission Monitoring System (CEMS) data reported by the power companies, which is stack based rather than emission unit based. A power plant may have several stacks. Each stack may vent emissions from one or more units at the plant. The two modeling cent ers also used different meteorological data—one

used data from the MM5 model and the other us ed National Weather Se rvice observation-based meteorology.

There are differences between results from th e two centers because of the differences in meteorological input data and also because of rounding when summing annual emissions. As a result the MM5-based modeling identified some stacks as being in the top 100 impacting a

MANE-VU Class I area that were not identifie d by the observation-based modeling, and vice versa. For purposes of identifying key stacks, all stacks on either list were included.

MARAMA combined the lists of the top 100 EG U stacks in Tables 10 and 20 from Appendix D

of the Contribution Assessment and eliminated both duplications and stacks that were outside the MANE-VU consultation area. (The consultation area includes states contributing at least 2% of

the sulfate monitored at MANE-VU Class I areas in 2002.) This process resulted in 167 unique stacks impacting one or more of the three MANE- VU Class I areas. The use of stacks rather than units or facilities was chosen as more consistent with the results of the modeling presented

in the Contribution Assessment. The Contribution Assessment Appendix D tables did not identify the units or facilities that were m odeled, only providing a CEMS Identification number.

### 28 MARAMA used information contained in IPM i nput files to match the plant name and type where the stack was located. The resulting list of 167 stacks is found in Appendix A of this

report.

MANE-VU asked states in the consultation ar ea to pursue 90 percen t control on all units emitting from those stacks by 2018. MANE-VU recognized that this level of control may not be

feasible in all cases. NESCAUM modelers inco rporated State comments gathered during the inter-RPO consultation process in estimating the imp act of this strategy on visibility at Class I areas. This process is desc ribed below in Section 5.5.

5.5 Implementation of MANE-VU Control Strategy for Key EGUs

As part of the MANE-VU strategy to improve vi sibility, MANE-VU asked states to pursue a 90 percent reduction in SO 2 

### emissions from the 167 EGU stacks identified as described in Section 5.4 and listed in Appendix A. MARAMA gather ed information from MANE-VU, MRPO, and VISTAS states and regional sta ff to obtain information about antic ipated emissions changes.

State and local agencies and individual stakeholders from MANE-VU, MRPO and VISTAS reviewed and revised the IPM results with respect to controls planned to come online. They also

reviewed the IPM results to ve rify that known and existing c ontrols and emission rates were properly reflected in the IPM r uns. In addition, commenters noted that some units predicted by

IPM to be shutdown would not shutdown.

Adjustments to the IPM results were made to sp ecific units using informa tion states had obtained as part of the permitting process or other contac t with the industry that indicated which units

would install controls as a re sult of CAIR and when these new controls would come on-line (Koerber, 2007; VISTAS 2007). In general, th e changes at specific E GUs provided by VISTAS reflected their Base G2 inventory, and, as di scussed with MRPO, the changes NESCAUM made

to emissions from sources in the MRPO were consistent with source s where controls were predicted in EPA’s IPM 3.0 run for 2018, since MRPO modeling relied on IPM 3.0. In addition to the 167 stacks, MANE-VU incorporated further corrections to source emissions as requested by VISTAS states at the following locations: North Carolina (Cliffside), South Carolina (Jefferies), Kentucky (Spurlock), and Virg inia (Chesapeake and Clinch River). .

NESCAUM determined the desired emissions leve ls for the 167 key stacks based on a 90 percent reduction in continuous emissions monitoring data from 2002. This established a target emissions level for the region from those stacks . NESCAUM compared these levels with the information provided by the states for those so urces. In each region, predicted 2018 emissions exceeded the target level. Therefore, emi ssions reductions from other EGU sources were considered in order to meet the target emissi ons reductions for the region (both within MANEVU and in other RPOs). This resulted in a net decrease in emissions in all three affected RPOs.

Emissions of SO 2 

### would have decreased by over 14,000 tons per year in MANE-VU, over 304,000 tons per year in the Midwest, and over 197,000 tons per year in the VISTAS region.

### 29 However, MANE-VU planners recognized that CAIR allows emissions trading, and that

reductions at one unit could be offset increases at another unit within the CAIR region. Because

most states do not restrict tr ading, MANE-VU decided that emi ssions should be increased to represent the implementation of the strategy for the 167 stacks within the limits of the CAIR program. Therefore, NESCAUM increased the emi ssions from states subject to the CAIR cap and trade program. For MANE-VU, 75,809 tons we re added back, leaving total regional emissions from the MANE-VU region greater than the original Inter-RPO IPM-based estimate but consistent with state projections. The rema ining 440,541 tons added b ack were allocated to

VISTAS and MRPO based on the fraction of their contribution to the total SO 2 

### emissions. The additional emissions correspond to an increase of 20.5 percent, with a total of 223,856 tons added to MRPO and 216,685 added to VISTAS.

Table 8 shows the emissions difference between the results of two IPM runs and the modeling inventories used by three Regi onal Planning Organizations (RPO s). VISTAS used Base G2, MANE-VU used the March 2008 Modeling Inventory, and MRPO used IPM 3.0..

MANE-VU 3/08 minus EPA 3.0 (negative numbers mean MANE-VU's modeling inventory was less than EPA 3.0) -34 -53 -142 -229



### The intent of the MANE-VU modelers’ final EGU emissions adjustments was to retain the same level of emissions as predicted by the RPO CAIR IPM run for the three re gions together, but to modify the locations of the emissions to better reflect the states’ estimates and to achieve

### 30 reductions at the 167 stacks identified as importa nt contributors to regi onal haze at MANE-VU Class I areas. As shown in Table 8, above, the MANE-VU adjustments resulted in total emissions from the three regions being less than the SO 2 

### emissions predicted by the RPO 2.1.9 IPM run but greater than emissions in the G2 i nventory used by VISTAS modelers. In both the MANE-VU and VISTAS regions, the MANE-VU Modeling Inventory is greater than the

VISTAS/Inter-RPO IPM run and in MRPO it is smaller. Results from IPM 3.0 also are provided for comparison, and are uniformly greater than the MANE-VU Modeling I nventory for EGUs.

All future EGU emissions estimates involve un certainty. MANE-VU be lieves its process of adding back emissions resulted in a reasonable, conservative estimate of the implementation of the MANE-VU request for a 90% reduction at key EGU facilities.

TOP ELECTRIC GENERATING EMISSI ON POINTS CONTRIBUTING TO

VISIBILITY IMPAIRMENT IN MANE-VU IN 2002

For each of three MANE-VU Class I Areas the 100 Electric Generating Unit (EGU) stacks with the most significant 2002 impact on visibilit y impairment were identified by CALPUFF modeling conducted by two modeling centers. 2 

### Many of these stacks have a regional impact and therefore significantly impact more than one Cla ss I Area. When the “Top Impacting” stacks for each of the three areas are aggregated into a single group there are 167 individual “Top Impacting” stacks identified. Fi gure A-1 indicates the location of the 167 stacks, and the tables following the map provides identif ying information, emissions us ed in the CALPUFF modeling, and predicted impacts.

The following information may be found in the listed columns of Table A-1:

1. Row Number (1 through 167)

2. CEMS Unit ID: an arbitrary number identifying the CEMS unit

3. ORIS ID: a standard identification number associated with each unit

4. Acadia MM5: The rank of this source based on its predicted sulfate ion annual impact on Acadia in 2002 using meteorologi cal data from the MM5 model. (A blank in columns 4, 5, 6, 7, 8, or 9 indicates this source was not among the top 100 for this Class I area as predicted by the indicated model.)

5. Acadia VTDEC: The rank of this source in terms of its predicted sulfate ion annual impact on Acadia in 2002 using National Weather Service data.

6. Brig MM5: The rank of this source in term s of its predicted sulfate ion annual impact on Brigantine in 2002 using meteorological data from the MM5 model.

7. Brig VTDEC: The rank of this source in terms of its predicted sulfate ion annual impact on Brigantine in 2002 using National Weather Service data.

8. Lye MM5: The rank of this source in terms of its predicted sulfate ion annual impact on Lye Brook in 2002 using meteorological data from the MM5 model.

9. Lye VTDEC: The rank of this source in te rms of its predicted sulfate ion annual impact on Lye Brook in 2002 using National Weather Service data.

10. MM5 2002 SO 2 

### Tons per Year: Emissions calcula ted from CEMS data and used by modelers who used the MM5 generated meteorological data

11. VTDEC 2002 SO 2 

### Tons per Year: Emissions calcu lated from CEMS data and used by modelers who used the national weathe r service generated meteorological data

12. Plant Number (1 through 105): The 167 stacks are located at 105 plants.

13. Plant Name—table is in alphabetical order by plant within each state

14. Plant Type: coal fired or oil/ga s fired electric generating units

15. State Name—table is in alphabetical order by state

16. State Code

2 For more information and detailed modeling results, see Appendix D: Source Dispersion Model Methods, in

NESCAUM 2006a.

### 38 Note that this list was created using 2002 emissions. By 2018 some of the units using these

stacks will have emission controls installed or be repowered or s hut down. This list represents

the EGU stacks that had the la rgest individual impacts on baseline visibility in 2002 at three

MANE-VU Class 1 areas.

Table A-2 presents predicted 2018 emissions estimate s for the same list of key stacks. Column 6 of Table A-2 gives the 2018 emissions predic ted by the IPM run VISTAS_PC_1f. Column 7

lists the revised 2018 emissions used in MANE-VU’s March 2008 modeling. Column 8 provides the basis for revising the emissions. See Section 5.5 of this report for more

information.
