### 3 A. Overview

MARAMA has awarded a contract to ICF Resources, L.L.C. (ICF), seeking ICF’s services to evaluate the impact of EPA’s CAIR Policy and the Mid-Atlantic/Northeast Visibility Union (MANE-VU) CAIR Plus proposal on the electric generating sector for the contiguous United States using the Integrated Planning Model (IPM ® 

### ).

IPM is a dynamic linear optimization model that can be used to examine air pollution control policies for various pollutants throughout the contiguous U.S. for the entire electric power system. The dynamic nature of IPM enables the pr ojection of the behavior of the power system over a specified future period. The optimizati on logic determines the least-cost means of meeting electric generation and capacity requirements while complying with specified constraints including air pollution regulations, transmission bottlenecks, and plant-specific operational constraints. The versatility of IPM allows users to specify which constraints to exercise and populate IPM with their own datasets.

This report summarizes the analysis that ICF has performed in evaluating the impact of the CAIR Plus proposal in the CAIR Plus region on the electricity generating sector by using IPM (hereafter, the analysis is referred to as the MA RAMA analysis). As part of this analysis, ICF has also developed a Base Case that implem ents EPA’s CAIR, CAMR and CAVR policies. The model assumptions and data used in this analysis are presented in Section B. The results are presented in Section C and the analysis limitations are presented in Section D.

Since the modeling is based on analyses dev eloped by U.S. EPA, VISTAS and LADCO, we have summarized only the incremental changes that were proposed by MARAMA as part of this analysis. The documentation for EPA’s v2.1.9 and v3.0 base cases is available at http://www.epa.gov/airmarkets/progsregs/epa-ipm . The VISTAS study assumptions are summarized in Appendix 1 and 2.

B. Modeling Assumptions and Changes Made to VISTAS Run

The MARAMA analysis is based on the recent IPM based analysis performed for VISTAS except for changes made by MARAMA. These runs are based on the VISTASII_PC_1f run that was developed for VISTAS in 2005. As per direction from MARAMA, the following assumptions for modeling the MARAMA Base Case-CAIR/ CAMR/CAVR (MARAMA 5c) and MARAMA CAIR Plus Policy Case (MARAMA 4c) were implement ed. Detailed assumptions are summarized in Appendix 3.

a) Run year configuration : The run year configuration was updated to separate out the key analysis years of 2009, 2012 and 2018. The revised configuration is summarized in Table 1:

### 4 Table 1: Run Years in MARAMA Base Case and MARAMA CAIR Plus Policy Case Run Year Calendar Years 2008 2007-2008 2009 2009-2009 2010 2010-2011 2012 2012-2012 2015 2013-2017 2018 2018-2018 2020 2019-2022 2026 2023-2030

b) Natural Gas Prices : As per direction from MARAMA, ICF implemented the EPA Base Case v3.0 natural gas supply curves that were based on ICF’s NANGAS (North American Natural Gas Analysis System) model as part of this analysis. These gas supply curves are documented in the EPA Base Case v3.0 documentation published on its website. The gas supply curves used in the VISTAS analysis were based on the EPA Base Case v2.1.9. The gas supply curves used in the MARAMA analysis will result in higher gas prices as compared to the VISTAS analysis. For example, for a 5 quad gas consumption in the power sector, the Henry hub gas price using the EPA Base Case v3.0 gas supply curves will result in a gas price that is approximately 40-60% (based on the run year) higher than if EPA Base Case v2.1.9 gas supply curves were used.

c) Fuel Oil Prices : The fuel oil price projections from AEO 2006 were implemented in the MARAMA analysis and are higher as compared to the VISTAS analysis. The fuel oil price projections used in the VISTAS analysis were based on AEO 2005. The AEO 2006 assumptions are documented in the EPA Base Case v3.0.

d) SCR and Scrubber Feasibility Limits : Table 2 summarizes the cumulative SCR and scrubber feasibility limits that were implement ed (in the MARAMA analysis) in the years 2008, 2009 and 2010. These limits are beyond existing control installations and prevent the model from projecting a level of SCR and scrubber builds in the short-term that was higher than the industry’s capability to deliver. The feasibility limits in 2008 and 2009 are based on actual planned SCR and scrubber installations. The 2010 limit for scrubbers is based on a projection for installation of SO 2 

### scrubbers under CAIR. It is based on an internal analysis that accounted for the 2008/2009 feasibility limits. In the VISTAS study, feasibility limits for SCR and scrubbers were not applied in 2008, 2009 and 2010.

Note that in 2008, 2009 and 2010 run years, the individual unit level decisions were not hardwired but IPM will choose to build only the most economic SCRs and scrubbers up to those limits.

Table 2: Cumulative SCR and FGD Feasibility Limits in MARAMA Base Case and MARAMA CAIR Plus Policy Case Runs Year SCR (GW) Scrubbers (GW) 2008 9 31 2009 15 51 2010 No Limit 69 Note: The above limits are incremental to thos e that are already installed on existing units as assumed in NEEDS.

### 5 e) CAVR (Clean Air Visibility Rule) : Consistent with U.S. EPA’s implementation of the CAVR rule, MARAMA has implemented the C AVR rule beginning in the run year 2015 within the MARAMA Base Case and MARAMA CAIR Plus Policy Case runs.

CAVR SO 2 

### Requirements : All CAVR eligible, unscrubbed, non CAIR and non WRAP affected sources larger than 200 MW are required to meet an output emission rate of 0.15 lbs/MMBtu of SO 2 

### or achieve 95% removal. However, only the option to meet the 0.15 lbs/MMBtu of SO 2 

### emission rate was provided in IPM. This assumption was based on the results from a comparison of output SO 2 

### emission rates of unscrubbed CAVR affected units in the VISTAS analysis when adjusted for a 95% removal with 0.15 lbs/MMBtu. The 0.15 lbs/MMBtu rate limit was always higher and hence is a lower cost strategy.

CAVR NO x 

### Requirements : All CAVR eligible, non CAIR affected sources larger than 200 MW are required to install combustion controls. SCRs are also required if the affected units are cyclone fired. All existing SCRs are required to operate annually.

Note that CAVR eligible sources in the above discussion imply the list of CAVR affected sources that U.S. EPA had modeled in their C AVR analysis using IPM. A list of units affected by the CAVR SO 2 

### and NO x 

### requirements are shown in Appendix 3 (tables A3.5a and A3.5b respectively).

f) Title IV SO 2 

### Bank : The IPM modeling time period in the MARAMA analysis is 2007- 2030. In order to capture the dynamics of the SO 2 

### allowance market pre 2007, MARAMA has implemented a Title IV SO 2 

### allowance bank of 6.43 million tons going into the year 2007. This assumption is based on an internal ICF analysis of the current market conditions.

g) Applicable States for Programs: The MARAMA CAIR Plus Policy Case run is based on the MARAMA Base Case run with the MARAMA CAIR Plus Policy Case proposal implemented as a replacement of the CAIR policy. Figure 1 shows a U.S. map with states affected by CAIR and CAIR Plus policies highlighted.

### Budgets : Table 3 summarizes the NO x 

### budgets implemented in the MARAMA Base Case and MARAMA CAIR Plus Policy Case runs, and Table 4 summarizes SO 2 

### allowance retirement ratios implemented in the MARAMA Base Case and MARAMA CAIR Plus Policy Case runs. The NO x 

### budgets under the Base Case and CAIR Plus policy cases in Table 3 are not comparable because there are more states in the CAIR Plus domain as compared to the CAIR domain in the Base Case. In IPM, em issions budgets are modeled as a cap that all affected sources together are required to comply with. These sources can buy or sell emission allowances among themselves and bank for future use under favorable economics.

C. Results

In this section, ICF has presented the costs, control installations, emissions, allowance market impacts, delivered fuel prices, generation, po wer plant retirements and new builds from the MARAMA Base Case and then compared these results with those from the MARAMA CAIR Plus Policy Case run. Appendix 5 summarizes the SO 2 

### and NO x 

### emission results and production cost components on a state and RPO level. The following paragraphs discuss the results from the two runs.

1. Production Costs

IPM projects the production cost of the U.S. power sector for each of the modeled run years. The production cost includes the annualized capital co sts of new investment decisions (includes control equipment costs and new build costs), fuel costs and the total variable and fixed operation and maintenance (O&M) costs of power pl ants. Allowance costs are not listed as a separate category because on a region wide basis the net cost is zero (number of allowances

### 8 purchased is equal to the number of allowances so ld). The administrative costs related to the purchase and sale of allowances are not modeled in IPM. The annualized incremental cost 1 

### of the MARAMA CAIR Plus Policy as compared to MARAMA Base Case is summarized in Table 5. The analysis projects a total cost of $10.7 billion in 2009 & $2.6 billion in 2018 respectively. Note that the cost of the policy is highest in 2009 (higher fuel costs being the main contributor of higher production costs) and then decreases starting 2010. This is because in 2009 there are limitations to the number of units that can install SCRs. In 2010 however, these limits are relaxed. In order to comply with the tight NO x 

### regulations and the limitations on SCR installations, the power sector increases natural gas-fired generation. In 2009 in the MARAMA CAIR Plus Policy Case the gas consumption increases by 812 TBtu and $0.85/MMBtu. This increase in gas consumption and the gas price result in a spike in fuel costs. Note that these costs are for the entire U.S. power sector and the policy could affect states that are within and outside the CAIR Plus region.

Table 5: Incremental Cost of the MARAMA CAIR Plus Policy Case Compared to MARAMA Base Case -- US Power Sector (1999 Billion Dollars) 2008 2009 2010 2012 2015 2018 Variable O&M Cost 0.04 0.01 0.32 0.51 0.41 0.28 Fixed O&M Cost 0.01 -0 .03 0.12 0.29 0.20 0.13 Fuel Cost 0.04 10.40 0.17 -0.90 0.04 0.23 Annualized Capital Cost 0. 26 0.31 1.58 2.43 2.12 1.93 Total Production Cost 0.36 10.69 2.19 2.33 2.77 2.57 Note: To convert year 1999 dollars to year 2006 dollars, use a conversion factor of 1.1856



### The marginal costs 2 

### of emission reductions as manifested in the projected allowance prices in the MARAMA Base Case and the MARAMA CAIR Pl us Policy Case are shown in Table 6. The SO 2 

### and NO x 

### allowance prices in the CAIR Plus region in the MARAMA CAIR Plus Policy Case run are high starting in 2009 due to the relatively tighter policies applied to the CAIR Plus region as compared to the SO 2 

### and NO x 

### policies in the MARAMA Base Case. Tighter policies result in more expensive compliance options being chosen resulting in higher allowance prices. The NO x 

### allowance prices are high in 2009 and drop in 2010 because the SCR feasibility limits are relaxed starting in 2010. In 2009, due to limitations on SCR installations, a significant increase in natural gas fired generation occurs, driving up the annual NO x 

### allowance prices. Starting in 2010, SCRs are installed resulting in a reduction in the use of more expensive NO x 

### reduction options such as natural gas generation, driving down the annual NO x 

### allowance prices.

The compliance options available to power plants to reduce both annual NO x 

### emissions and the ozone season NO x 

### emissions are same. In addition the plants affected by the ozone season NO x 

### policy and the annual NO x 

### policy in the MARAMA CAIR Plus Policy Case are identical. A plant that installs a NO x 

### control option such as a SCR will be able to reduce emissions in both the ozone season and the non ozone season and hence simultaneously affect CAIR/CAIR Plus annual NO x 

### and ozone season NO x 

### allowance markets. It appears that complying with the annual NO x 

### policy results in an over compliance with the ozone season NO x 

### policy and is highlighted by the zero ozone season NO x 

### allowance price starting 2010.

1 Annual Incremental Production Cost = Annualized Produ ction Cost of MARAMA CAIR Plus Policy Case – Annualized Production Cost of MARAMA Base Case.

2 Marginal cost is defined as the cost of reducing one additional ton of emissions.

### 2. Projected Control Technology Retrofits Installation of controls is one of the strategies that the power sector opts for complying with the CAIR Plus proposal requirements. This strategy is in addition to other compliance strategies such as changes to fuel switching, plant retirements, plant dispatch and new builds. Under the MARAMA CAIR Plus Policy Case, an additional 19.5 GW of SO 2 

### scrubbers and 77.8 GW of selective catalytic reduction (SCRs) are instal led by 2012 (see Table 7). In the MARAMA CAIR Plus Policy Case, the SCR feasibility limits in 2008 and 2009 run years and the SO 2 

### scrubber limits in 2008 and 2010 run years are achieved.

### 10 3. Emissions

Tables 8 and 9 summarize the SO 2 

### and NO x 

### emissions from all units including both fossil and nonfossil units in the MARAMA Base Case and the MARAMA CAIR Plus Policy Case in the 2008, 2009, 2010, 2012, 2015 and 2018 run years. The projected state-level emissions for SO 2 

### and NO x 

### for the MARAMA CAIR Plus Policy Case and the MARAMA Base Case are presented in Tables A5.1-A5.3 in Appendix 5.

Note, that the CAIR/CAIR Plus policies are not applied to the WRAP region in the MARAMA Base Case and MARAMA CAIR Plus Policy Case runs, and hence the SO 2 

### and NO x 

### emissions in the two runs in the WRAP region are similar. The CAIR/CAIR Plus NO x 

### programs start in 2009. Hence, the NO x 

### emissions are lower starting in 2009. The NO x 

### emissions in CAIR Plus region in Table 9 do not match the corresponding NO x 

### budgets in Table 3 because NO x 

### emissions in Table 9 include emissions from both CAIR Plus affected and not affected units.

The CAIR/CAIR Plus SO 2 

### programs start in 2010. However, the SO 2 

### emissions are lower prior to 2010 because Title IV SO 2 

### allowances that are banked prior to 2010 can be used to comply with the CAIR/CAIR Plus provisions starting 2010.

Both the CAIR and CAIR Plus programs are cap and trade policies. Therefore, while the CAIR Plus policy is more stringent than the CAIR policy, emissions can still go up in individual states in MARAMA CAIR Plus Policy Case as compared to MARAMA Base Case.

### 5. Fuel Consumption and Prices

Table 11a summarizes the coal and natural gas consumption in the U.S. power sector as projected by IPM in the MARAMA Base Case and MARAMA CAIR Plus Policy Case runs. Table 11b summarizes the delivered coal and natural gas prices solved by IPM in the MARAMA Base Case and MARAMA CAIR Plus Policy Case runs. The delivered gas prices are not inputs to the model but are determined endogenously by equilibrating demand and supply.

In the MARAMA Base Case, the natural gas prices in 2008 are higher than 2009. This is due to differences in the supply curves for the two year s. As an example, for a gas consumption level of 5,696 TBtu, the gas price in 2008 is $7.23/MMbtu. However, at the same level of gas consumption, the gas price in 2009 would be at $6.12.

The fuel costs shown in Table 5 are incremental costs (i.e. MARAMA CAIR Plus Policy Case – MARAMA Base Case). The increase in fuel costs of $10.4 billion dollars in 2009 is a result of the incremental increase in natural gas prices of $0.85MMBtu between the two cases (i.e. $7.83/MMBtu in the CAIR Plus Policy case versus $6.98 in the MARAMA Base Case) and an increase in natural gas consumption 812 TBtu.

The gas prices are higher in most years in the MARAMA CAIR Plus Policy Case, in comparison to the MARAMA Base Case. This is a result of an increase in gas consumption as shifting from coal to gas is a compliance option leading to higher gas prices. In 2009 the gas prices increase is the highest because of restrictions on new SCR builds which result in an increase in gas consumption by 812 TBtu.

### 6. Power Plant Retirements

A tighter environmental policy increases the total production costs of a power plant, including its compliance costs, and thus could make it uneconomic. Table 12 summarizes the power plant retirements in the MARAMA Base Case and the MARAMA CAIR Plus Policy Case. Note that the more stringent CAIR Plus policy results in an increase in total retirements by 4.9 GW in 2009. Oil/gas steam units that are uneconomic to run under the CAIR Plus policy retire. Increase in natural gas use as presented in Table 11a is accounted for by the remaining gas fired units that have relatively lower costs of operation.

### 15 7. Power Plant Generation

Changes in power plant generation is one of the compliance strategies for meeting a tighter environmental policy. In the MARAMA CAIR Plus Policy Case as compared to the MARAMA Base Case, the generation mix changes towards lower emission intensive fuel and plant types. Table 13 summarizes the generation mix in the MARAMA Base Case and the MARAMA CAIR Plus Policy Case. Note that there is an increase in natural gas fired generation (from combined cycles, combustion turbines and oil/gas steam units) and a reduction in coal fired generation (from coal steam and IGCC units) in all years except 2012. The overall increase in coal fired generation in 2012 occurs because it is the first year when the scrubber feasibility limits are no longer applicable resulting in an increase in scrubber installations and a relatively lower drop in generation from the coal steam units. Coal generation in 2010 is also not higher due to the presence of scrubber limits. In years after 2012, the SO 2 

### and NO x 

### policies in the MARAMA CAIR Plus Policy Case continue to become more stringent resulting in an increase in gas based generation.

The electricity demand in both the MARAMA Base Case and the MARAMA CAIR Plus Policy Case are identical. However the power generation in the two runs is different due to differences in transmission and pump storage losses.

### 17 8. New Power Plant Builds

Table 14 summarizes the new power plant builds in the MARAMA Base Case and the MARAMA CAIR Plus Policy Case. In the MARAMA CAIR Plus Policy Case, new builds are higher than in the MARAMA Base Case because of a need to compensate for the increase in power plant retirements as presented in Table 12 and to take advantage of the relatively cleaner emission profiles of the new technologies.

New IGCC’s have lower emission rates and lower heat rates making them more valuable under a stringent environmental policy. Hence IGCC’s are built in 2010 and 2012 in the MARAMA CAIR Plus Policy Case and not in the MARAMA Base Case.

In 2018, the SO 2 

### allowance retirement ratio increases from 3.32 to 4.16. This increase results in a drop in coal fired generation and an increase in natural gas fired generation. In order to support this increase, in 2018 there is a significant increase in new combined cycle capacity that is more cost effective for base and intermediate load operation and a corresponding decrease in new combustion turbine capacity that is cost effective for peak load operation.

### 18 D. Limitations of Analysis

MARAMA modeling using IPM is based on various economic and engineering input assumptions that are inherently uncertain, such as assumptions for future fuel prices, electricity demand growth and the cost and performance of control technologies. As configured, IPM does not take into account demand response (i.e., consumer reaction to changes in electricity prices).

### 19 Appendix 1: Summary of Changes to EPA Base Case v2.1.9 by Vistas

The EPA Base Case v.2.1.9 was dev eloped by ICF under th e direction of the U.S. Environmental Protection Agency (EPA). It serves as the starting point for the anal ysis presented in this report. Subsequent to its release the VISTAS Regional Pl anning Organization initiated a two-phase study using IPM. Starting with the EPA 2.1.9 as a base, VIST AS, along with study parti cipants from CENRAP and LADCO RPOs, made several changes to the underlyi ng datasets and modeling assumptions. The starting point for the MARAMA analyses discussed in this re port was work from the VISTAS study as modeled in the run VISTASII_PC_1f.

VISTAS and its workgroup initiated a review of N EEDS and recommended a large number of changes to the data. This occurred in two phases. In addition to unit level changes, VISTAS and its workgroup made a number of global changes that are reflected in this case. These are briefly described below:

• Demand forecast were changed to reflect unadju sted EIA AEO 2005 national electricity and peak demand values.

• AEO 2005 data was used for all assumptions regarding new builds of conventional technologies. The cost and performance assumpti ons for these units were as per the AEO 2005 documentation, while assumptions for r enewable capacity were the same as those used in the EPA Base Case 2004 v.2.1.9.

• For nuclear units, the cost of continued operation was updated to approximately $27 per kilowatt-year based on AEO 2005.

• Hardwired Duke Power and Progress Energy cont rol technology investment strategies for complying with the North Carolina Clean Smoke Stacks rule.

• The renewable portfolio standards (RPS) is modeled based on the most recent RGGI documentation using a single RPS region fo r Massachusetts (MA), Rhode Island (RI), New York (NY), New Jersey (NJ), Maryland (MD) and Connecticut (CT). The RPS requirements within these states can be met by renew able generation from New England, New York and PJM. EPA Base Case 2004 v.2.1.9 methodology and EIA AEO 2004 projected renewable builds were used for the rest of the regions.

• The run years used were 2008 (2007-2008), 2009 (2009), 2012 (2010-2013), 2015 (2014- 2017), 2018 (2018), 2020 (2019-2022), and 2026 (2023-2030).

• The Clean Air Mercury Rule (CAMR) was modeled.

### 20 Appendix 2: MANE-VU IPM Global Parameter Decisions

This section summarizes the decisions as made by MANE-VU for global assumptions to be used in EGU forecasting with IPM as part of the VISTAS analysis. These decisions and changes are made to EPA Base Case version 2.1.9 assumptions.

A. Market Assumptions

1. National Electricity and Peak Demand Decision : Use unadjusted EIA AEO 2005 national electricity and peak demand values. (This is the same as the assumption used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)

2. Regional Electricity and Demand Breakout Decision : Use the existing IPM region breakdown as conducted in earlier modeling. (This is the same as the assumption used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)

3. Natural Gas Supply Curve and Price Forecast Decision : Use fuel supply curves and fuel price forecast s from IPM version 2.1.9. These are the same fuel price forecasts and supply curve assu mptions used in EPA’s latest CAIR runs.

(This is the same as the assumption used by VIST AS, MRPO, and CENRAP. See e-mail from Megan Schuster dated 7/5/05.)

4. Oil Price Forecast Decision : Use fuel supply curves and fuel price forecast s from IPM version 2.1.9. These are the same fuel price forecasts and supply curve assu mptions used in EPA’s latest CAIR runs.

(This is the same as the assumption used by VIST AS, MRPO, and CENRAP. See e-mail from Meagan Schuster dated 7/5/05.)

5. Coal Supply and Price Forecast Decision : Use fuel supply curves and fuel price forecast s from IPM version 2.1.9. These are the same fuel price forecasts and supply curve assu mptions used in EPA’s latest CAIR runs.

(This is the same as the assumption used by VIST AS, MRPO, and CENRAP. See e-mail from Megan Schuster dated 7/1/05.)

B. Technical Assumptions

1. Firmly Planned Capacity Assumptions Decision : Use revisions and new data as pr ovided by RPOs and stakeholders. Decision : Allow NC Clean Smokestacks 2009 data as provided to define “must run” units. (These are the same as the assumptions used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)

2. Pollution Control Retrofit Cost and Performance [SO2, NOx, Hg] Decision : Retain pollution control retrofit cost and performance values. (This is the same as the assumption used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)

3. New Conventional Capacity cost and performance assumptions Decision : Use EIA AEO 2005 cost and performance assumptions for new conventional capacity. Decision : Retain existing 2.1.9 framework cost and performance for new renewable capacity. Decision : Exclude constraint on new capacity type builds (i.e., no new coal). (These are the same as the assumptions used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)

4. SO 2 Title IV Allowance Bank

### 21 Decision : Use existing SO2 allowance bank value (4.99 million tons) for 2007. (This is the same as the assumption used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)

5. Nuclear Re-licensing and Uprate Decision : Use existing IPM configuration with updat ed EIA AEO 2005 (~$27/kW) incurrence cost for continued operation. (This is the same as the assumption used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)

C. Strategy Assumptions

1. Clear Air Mercury Rule (CAMR) Decision : Include CAMR in future rounds of IPM modeling. (This is the same as the assumption used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)

2. Renewable Portfolio Standards Decision : Model RPS based on the most recent RGGI doc umentation using a single RPS region for MA, RI, NY, NJ, MD and CT. The RPS requirements within these states can be met by renewable generation from New England, New York and PJM. EPA 2.1.9 methodology and ha rdwired EIA AEO 2004 projected renewable builds for the remainder of the country. (This is the same as the assumption used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)

D. Other Assumptions

1. Run Years Decision : Parsed output data will be provided for 2009, 2012 and 2018. Run years to 2008, 2009, 2012, 2015, 2018, 2020, and 2026. (Run Year 2008 [2007-2008], Run Year 2009 [2009], Run Year 2012 [2010-2013], Run Year 2015 [2014-2017], Run Year 2018 [2018], Run Year 2020 [2019-2022] and Run Year 2026 [2023-2030] (This is the same as the assumption used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)

2. Canadian Sources Decision : Utilize existing v.2.1.9 configurati on (no Canadian site specific sources). (This is the same as the assumption used by VISTAS, MRPO, and CENRAP. See 5/11/05 Inter-RPO IPM Global Decisions memo.)
