Subject: WRAP PRP18b Emissions Inventory

– Revised Point and Area Source Projections

Date: April 29, 2009 (Revised October 16, 2009 1 

# )

INTRODUCTION

The WRAP 2018 point and area sources’ “base cas e” emissions projection inventory was first

compiled in January 2006. 2 

# That 2018 projection inventory was revised in June 2007 to provide the

technical basis for making preliminary evaluations of reasonable progress toward individual Class I

area visibility goals by the WRAP. 3 

# The June 2007 revision, called the 2018 Preliminary

Reasonable Progress version “a” (PRP18a ) emissions inventory, focused on the most significant

point and area sources of visibility-impairing pollution within each state and Native American

Reservation (NAR), and on the specific source cat egories whose 2018 emissions were known to be

incorrect or needed to be revised. This PRP18a effort included updating projections of electric

generating units (EGUs) and incorporating th e effects of known and presumed Best Available

Retrofit Technology (BART) emission lev els, primarily for BART controls of SO 2 

# emissions.

The objective of this current project, the 2018 Preliminary Reasonable Progress version “b”

(PRP18b) analysis is to make a second revision to the 2018 emissions inventory projections for point

and area sources in the WRAP region to provide a more current assessment of the reasonable

progress toward visibility goals by the WRAP. The focus of this project was to address specific

changes that have occurred since January 2007 in these areas:

x BART determinations (or expected BART contro l levels where BART had not been finalized);

x Projections of “future” fossil -fuel plants needed to achieve 2018 federal electrical generation

demand forecasts;

x New rulemaking, permit limits, and consent decrees; and

x Other outstanding issues that were identified by the federal, state, or local agencies within the

WRAP domain as needing to be corrected or updated.

# SCOPE

The scope of this project covers stationary point and area sources located within the states of Alaska,

Arizona, California, Colorado, Idaho, Montana, Ne vada, New Mexico, North Dakota, Oregon, South

Dakota, Utah, Washington, and Wyoming, plus tribal sources within the WRAP region.

The PRP18b inventory includes point and area sour ces (excluding some area sources covered by

other inventories, such as fugitive dust, fires, and area ammonia sources) emitting the following air

pollutants: nitrogen oxides (NO

x 

# ), sulfur dioxide (SO 2 

# ), volatile organic compounds (VOC), carbon

monoxide (CO), particulate matter (PM) with an aerodynamic diameter of less than 10 micrometers

( μ m) (PM 10 

# ) and less than 2.5 μ m (PM 2.5 

# ), and ammonia (NH 3 

# ).

The deliverables produced under this project includ e, in addition to a draft and final technical

memorandum, WRAP PRP18b inv entory pivot tables (similar to those provided under ERG’s

previous projects). ERG also provided PRP18b fi les formatted for modeling (i.e., SMOKE/IDA

format) and for use in the WRAP EDMS (i.e., NIF3.0).

METHODOLOGY

Using the PRP18a emissions inventory (June 2007) as a basis, spreadsheets were developed that

contained multiple worksheets for each federal or state agency containing the following information:

x BART sources and PRP18a emission rates

– Listing of BART eligible or subject sources

according to the most recent WRAP BART “Clearinghouse” spreadsheet (2008 -10-24_WRAP

BART Tracking Sheet.xls). Where applicable, the BART emission limits and/or presumptive

BART emission limits used in the PRP 18a emissions inventory were listed.

x Future EGUs

– Listing of plants that were included in the PRP18a inventory as either permitted

for construction, or under construction.

x Leftovers

– Comments and responses from previous WRAP inventory versions (Plan02d and

PRP18a) for potentially needed revisions for the PRP18b inventory.

The spreadsheets containing the three worksheets were transmitted via e-mail to each relevant

agency. Telephone conferences were held with each agency during December 2008 to review the

spreadsheets, answer questions, and establish deadlines for submittal of information by the agencies

to ERG. After each agency responded, updates were made to the PRP18a inventory to reflect the

changes. The result is the draft PRP18b point and area source emissions inventory.

# The Regional Haze Rule explicitly recognized the authority of trib es to implement the provisions of the Rule, in accordance wi th

principles of Federal Indian law, and as provided by the Clean Air Act §301(d) and the Tribal Authority Rule (TAR) (40 CFR

§§49.1-.11). It is our hope that the finding and recommendations in this report will prove useful to tribes, whether they choos e to

submit full or partial 308 or 309 Tribal Implementation Plans (TIPs), or work with the U.S. EPA to develop Federal Implementati on

Plans (FIPs). The authors of this memo have strived to ensure th at all references to tribes in the document are consistent with

principles of tribal sovereignty and autonomy as reflected in the regulatory framework. Any inconsistency with this framework i s

strictly inadvertent and not an attempt to impose requirements on tribes which are not present under existing law.

# Revisions to the 2018 Emissions Inventory

The revisions made as a result of this project are su mmarized below. These fe ll into three different

categories: revised EGU projections, BART emission limits, and other miscellaneous changes.

Revised EGU Projections

For the PRP18b inventory, ERG updated the analysis of future coal-fired EGUs (i.e., units that will

need to be built in order to meet future projected electricity demand). ERG obtained the most recent

energy generation projections from the Annual Energy Outlook (AEO), which is published annually

by the Energy Information Administration (EIA). 5 

# The original 2018 base case inventory relied

upon EIA projections released in 2005; the PRP18a analysis used EIA projections released in

February 2007; and, this PRP18b analysis used the mo st recent EIA projections released in February

2008. A comparison of the three sets of energy generation projections is shown in Table 1. The

most recent 2008 energy generation projection indicates a significant decrease of 20 percent in the

required 2018 coal-fired electricity generation for the WRAP domain, as compared to the previous

projection.

# Two primary reasons were identified for this decreas e in projected coal-fired electricity generation.

First, several underlying economic fundamentals within the Annual Energy Outlook model were

revised. For instance, the annual gross domestic product (GDP) growth rate was assumed to be 2.8

percent in both the 2005 and 2007 projections (i.e., th e left and middle scenarios in Table 1); in the

2008 projection (i.e., the right scenario in Table 1) the annual GDP growth rate was revised down to

2.4 percent. Likewise, the annual electricity de mand growth rate was adjusted downward from 1.5

percent in the 2007 projection to 1.1 percent in the 2008 projection. 6 

# Although both of these

adjustments were less than half a percent each, over the 16 year period between 2002 and 2018 the

effects become more significant.

# Second, impacts from state renewable port folio standards (RPSs) were included. 7 

# Although state

RPSs existed previously, the 2008 Annual Energy Outlook was the first time that EIA attempted to

incorporate the effects of the state RPSs into their energy demand modeling. 8 

# As of June 2008, 25

states had established RPSs, of which 8 were WR AP states (i.e., Arizona, California, Colorado,

Montana, Nevada, New Mexico, Oregon, and Washington). The 2008 Annual Energy Outlook

incorporated the state RPSs as aggregated regional factors. The aggregated regional RPS factors

used in EIA’s 2008 modeling are presented in Table 2.

# The documentation of AEO assumptions indicates that “only targets with established enforcement

provisions or established state funding mechanis ms were included in the calculation; goals,

provisional RPS requirements, or requi rements lacking established funding were not included.” As

an example, California is not included in Table 2, because the state’s RPS is su bject to limitations of

state funding. For California, the AEO electricity generation projections only incorporate the

additional renewable capacity based upon currently authorized funds through 2011. The

documentation of AEO assumptions also states that “compliance enforcement provisions vary

significantly among states and most states have established procedures for waiving compliance

through the use of ‘alternative compliance’ paymen ts, penalty payments, discretionary regulatory

waivers, or retail price impact limits. Because of the variety of mechanisms, even within a given

electricity market region, these limits were not modeled.”

The revised PRP18b analysis of future electricit y generation by coal-fired EGU plants is

summarized in Table 3. Based upon EIA’s most recent projection of coal -fired electricity for the

WRAP region (i.e., 320.69 billion kWh), the needed future new coal-fired EGU generation capacity

is only 61.99 billion kWh. This needed future coal -fired EGU generation capacity is more than

offset by capacity from three categories of sources:

x Unused capacity from existing EGUs included in the 2002 base year inventory;

x Capacity from EGUs that began operation after the 2002 base year;

x Capacity from EGUs that are currently being constructed or permitted.

Remaining Capacity to be Allocated 66.53 41.20 -40.50



# The unused capacity from existing EGUs was previously estimated to be 16.60 billion kWh and was

assumed to still be valid.

Only four coal-fired EGUs have been identified as beginning operation after the 2002 base year:

Wygen Station #1 and #2 in Wyoming, Hardin Station in Montana, and Springerville Unit #3 in

Arizona. The capacity of these four EGUs has been estimated to be 5.34 billion kWh.

A listing of coal-fired EGUs that are currently under construction or are being permitted was

originally developed for the 2018 base case anal ysis and was then expanded for the PRP18a

projections (i.e., the left and center portions of Tab le 4). As part of the PRP18b revision, the status

of these EGU facilities was confirmed with the states and other resources. The revised status of

these EGU facilities is located in the right portion of Table 4. As noted above, Wygen Station #2,

Hardin Station, and Springerville Unit #3 have all recently become operational and were removed

from the “Under Construction” classification; Wyge n Station #1 was already operating as part of the

2018 base case analysis and the PRP18a revision (i .e., indicated in Table 4 as 0.66 billion kWh of

capacity at post-2002 faci lities). Also, six facilities were moved from “Being Permitted” status to

“Under Construction” status (i.e., Springerville Unit #4, Comanche Unit #3, Newmont, Spiritwood,

Wygen Station #3, and Dry Fork). In addition, four f acilities have been cancelled (i.e., Ft. Morgan,

Akron, Gascoyne Station #1, and South Heart) and one facility will be switched to a natural

gas/wind facility (i.e., Highwood). Finally, three new coal-fired EGU projects have been identified

within the WRAP domain (i.e., Toquop and Ely Ener gy Center in Nevada and a 110 MW waste

coal-fired addition to the existing Bonanza EGU lo cated on tribal lands in eastern Utah). Emissions

for the Toquop and Ely Energy Center facilities we re provided by Nevada environmental staff, while

emissions for the Bonanza addition were obtained from the PSD permit provided by U.S. EPA,

Region 8 staff. The status of the EGUs that are cu rrently under construction or are being permitted

is fluid, but Table 4 represents the known status as of early February 2009.

Assuming that all future EGUs will operate at a cap acity threshold of 85 percent, then the estimated

generation capacity of the 6 EGUs under construc tion is 14.43 billion kWh, while the estimated

generation capacity of the 11 EGUs currently being permitted is 66.12 billion kWh. The sum total

of the available future generation capacity is 102.49 billion kWh (i.e., 16.60 billion kWh unused

capacity + 5.34 billion kWh capacity at post-2002 facilities + 14.43 billion kWh at under

construction facilities + 66.12 billion kWh at fa cilities currently being permitted). This total

available future generation capacity exceeds the needed future generation capacity (i.e., 61.99 billion

kWh); this excess capacity is represented in Table 4 by the value of -40.50 billion kWh by 67

percent. It should be noted that not all of the capacity currently being permitted will be built.

# However, if 39% of the new coal-fired EGU plant capacity currently in the permitting process is

brought on-line, then the 2008 coal-fired EI A projection for 2018 will be satisfied.

The PRP18a analysis included an additional 11 hypothetical model future 500 MW coal-fired EGUs

not specifically identified by states. These 11 mode l EGU plants were used to meet the estimated

41.20 billion kWh shortfall in future generation capacity that resulted from the PRP 18a AEO

analysis, and they were located throughout th e WRAP domain based upon proportional allocation of

existing generating capacity in WRAP states. The plants were identified in the database as either

“Future Coal EGU (A)” or “Future Coal EGU (B)”. Because of the revised excess future generation

capacity estimated in this PRP18b analysis, these hy pothetical model future EGUs are not needed to

meet a future generation capacity shortfall, and therefore all 11 such facilities have been deleted

from the PRP18b projections.

BART Emission Limits

As part of the PRP18a analysis, ERG collected information on specific BART SO 2 

# limits for all

coal-fired EGU sources subject to BART. Data we re available for Colorado, North Dakota, Utah, as

well as the Boardman EGU in Oregon. These were used in place of the 2018 base case projections

in the WRAP PRP18a inventory.

In addition to these specific BART limits, the presumptive limit of 0.15 lb SO 2 

# /MMBtu mandated by

the U.S. EPA BART Guideline was applied to a certain group of coal-fired EGUs. This presumptive

limit was applied to those coal EGUs that were de termined to be “Subject to BART”, but for which a

specific limit had not yet been determined. The 0.15 lb/MMBtu presumptive limit was also applied

to those coal EGUs that were “Eligible for BART”, but for which the responsible agency has not yet

completed the BART visibility impact analysis for final BART determination.

For the PRP18b analysis, ERG confirmed and, when necessary, updated the PRP18a coal-fired EGU

BART SO 2 

# emissions rates. ERG also obtained the proposed NO

x 

# reductions for these coal-fired

EGU sources. Finally, ERG obtained the proposed SO 2 

# and NO

x 

# reductions for the non-EGU sector

of BART sources, a sector for which no BART c ontrol information was solicited in the preparation

of the previous PRP18a inventory. The BART limi ts for coal-fired EGU sources are summarized in

Table 5, and BART limits for non-EGU sources are presented in Table 6. For the subject facilities

with no specific BART emission limits, a summary of changes made as a result of applying the

presumptive BART limits is shown in Table 7. In Table 5, the changes relative to the PRP18a

analysis are indicated. Due to the responses from state agencies, the number of sources with

specified BART emission limits (i.e., Table 5) has increased compared to th e PRP18a analysis, while

the number of sources with presumptive BART em ission limits (i.e., Table 7) has decreased.

Other Miscellaneous Changes

In addition to revised EGU projections and BART emission limits, there were a number of other

miscellaneous changes that were made during th e development of the PRP18b inventory. These

included the following:

x Modification of various inventory data to be c onsistent with the Plan 02d emissions inventory.

x Revision of a limited number of area source categor ies (i.e., fuel combustion emissions in South

Dakota and California, gasoline distribution emissions in Idaho, residential wood combustion

emissions in Washington, construction dust in [Clark County] Nevada).

x Revision of stack parameters based upon agency input.

The four miscellaneous changes listed above were discussed during the federal and state agency

telephone calls. In addition to these changes, there was one other change related to oil and gas

emissions data that was made that was not specifically discussed during the telephone calls.

The 2018 base case area source inventory contained oil and gas emissions data from the WRAP

Phase I oil and gas project. 9 

# During the modeling of the PRP18a inventory, a separate modeling

file of oil and gas emissions data was provide by another WRAP contractor (Environ) and this

data was obtained from the WRAP Phase II oil and gas project. 10 

# In order to avoid double

counting the oil and gas emissions provided by Environ in the separate modeling file, ERG’s

PRP18a area source emissions modeling file ex cluded oil and gas emissions. As a result, ERG ’s

June 18, 2007 technical memo also excluded these oil and gas emissions data.

The WRAP Phase II oil and gas emissions data have been added to the emission totals for both

the PRP18a inventory (Table 9b) and the PRP18b i nventory (Table 9c) in this technical memo, in

order to provide as complete an assessment as pos sible. Thus, Table 9b of this memo will not

match the area source emission inventory reported in the June 18, 2007 PRP18a technical memo.

In addition, the changes occurring between the PR P18a and PRP18b shown in Table 9e will not

reflect an “artificial increase” in emissions wh ich would otherwise be shown if oil and gas

emissions were added only to the PRP18b inventory. State level emission totals that include the

WRAP Phase II oil and gas emissions data are shaded in Table 9b and Table 9c.

Attachment 1 contains point sources summary tables for each state/tribe, which show the

following:

x Final 2018 base case emissions (previously submitted)

x Net changes made for the PRP18a analysis (i.e ., at the facility-, unit-, emission point- or

SCC-level) (previously submitted)

x Final PRP18a emissions (previously submitted)

x Net changes made for the PRP18b analysis

x PRP18b emissions

Attachment 2 contains similar summary tables for area sources.

It should be noted that the records that were deleted upon the request of the state/local agencies

are not itemized in these tables. The result of all deletions is shown as a single line item on each

table (if applicable), as these were extensive in many cases and would have made the length of

the tables unmanageable for this memo.
