Notice of Public Meeting and roposed Amendment and 

Reissuance General Permit Nu ber WDWGO 10000 

The Texas Commission on Enviro ental Quality (TCEQ) proposes 

to amend ru1d reissue the Class I U1 derground Injection Control (UIC) 

General Permit Number WDWGO 1 000 authorizing the use ofa Class I 

injection well to dispose of nonhaz rdous brine from a desalination operation or nonhazardous drinking ater treatment residuals (DWTR) . 

The proposed general permit (GP) pplies to the entire state of Texas. 

This GP is authorized by Texas W ter Code, §27.025. 

PROPOSED AMENDED GENE L PERMIT. The executive director has prepru·ed a draft amended G that authorizes the use of a Class I 

injection well to dispose ofnonhaz rdous brine from a desalination operation or nonhazardous DWTR.' e amendments of this existing GP 

would incorporate standards for di osal of nonhazardous D WTR that 

contain naturally occurring radioa tivc material (NORM) into a salt 

cavern in horizontally bedded or n-domal salt. These st<mdards require the owner or operator to atlai a performance standard to prevent 

the movement of fluids that would result in the pollution of an underground source of drinking water. 'he executive director proposes to 

reqtJire regulated facilities to subm a Notice ofintent to obtain authorization tor injection. A Radioacti e Materials License is required for 

disposal ofDWTR containing NO that docs not meet an exempted 

level for its radiological content. e proposed changes to the GP are 

included in the proposed GP and d scribed in the fact sheet. 

The executive director has revicwe this action for consistency with the 

goals and policies of the Texas Co tal Management Program (CMP) 

according to Coastal Coordination ouncil (CCC) regulations and has 

determined that the action is consis ent with applicable CMP goals and 

policies. 

A copy of the proposed amended P and fact sheet are available tbr 

viewing and copying at the TCEQ ffice of the Chief Clerk located at

EXECUTIVE SUMMARY 

In 2008, the commission adopted the Eight-Hour Ozone Redesignation Request and 

Maintenance Plan for the Beaumont-Port Arthur (BPA) Ozone Nonattainment Area (Project No. 

2oo8-oo6-SIP-NR), which fulfills all Federal Clean Air Act (FCAA) requirements to redesignate 

the BPA ozone nonattainment area (Hardin, Jefferson, and Orange Counties) to attainment of 

the 1997 eight-hour ozone standard and demonstrates continued attainment of that standard 

through 2021. The plan was approved by the United States Environmental Protection Agency 

(EPA) effective November 19, 2010, and the BPA area was redesignated to attainment for the 

1997 eight-hour ozone standard. The 2008 BPA maintenance plan contains on-road mobile 

emissions inventories, a nitrogen oxides (NOx) motor vehicle emissions budget (MVEB), and a 

volatile organic compounds (VOC) MVEB developed using the EPA's MOBILE emissions 

estimation model. On March 2, 2010, the EPA officially released a new model, the Motor Vehicle 

Emission Simulator (MOVES) model, to replace the MOBILE model for SIP applications. 

Beginning March 2, 2013, transportation conformity must be conducted using the MOVES 

model. To demonstrate transportation conformity, a nonattainment or maintenance area must 

show that its metropolitan transportation plans, transportation improvement programs, and 

projects funded by the Federal Highway Administration or the Federal Transit Administration 

conform to the MVEBs established in the state implementation plan (SIP). Conformity must be 

demonstrated before area transportation plans can be approved or funded by the United States 

Department of Transportation or the Metropolitan Planning Organizations. Updating MVEBs 

using MOVES-based on-road mobile emissions inventories requires a SIP revision. This 

proposed SIP revision would facilitate future MOVES-based transportation conformity 

determinations by providing MVEBs based on the latest version of the MOVES model, 

MOVES2010a. 

This proposed SIP revision would replace the 2008 BPA maintenance plan on-road mobile 

source emissions inventories for NOx and VOC based on the EPA's MOBILE model with those 

based on the EPA's MOVES model. On-road mobile source emissions inventory updates include 

those for 2005, 2011, 2014, 2017, and 2021. In addition, 2021 NOx and VOC MVEBs would be 

updated based on the MOVES-based emissions inventories. 

This proposed SIP revision includes documentation to satisfy the EPA's MOVES 

implementation policy guidance1 concerning updating maintenance plans with MOVES, which 

indicates that states must (1) demonstrate that the updated plan continues to meet all 

maintenance requirements and (2) document that growth and control strategy assumptions for 

all other source categories (area, non-road mobile, and stationary point) continue to be valid 

and any minor updates would not change the conclusions of the approved maintenance plan.

ES-1 
SECTION V-A: LEGAL AUTHORITY 

General 

The Texas Commission on Environmental Quality (TCEQ) has the legal authority to implement, 

maintain, and enforce theN ational Ambient Air Quality Standards (NAAQS) and to control the 

quality of the state's air, including maintaining adequate visibility. 

The first air pollution control act, known as the Clean Air Act of Texas, was passed by the Texas 

Legislature in 1965. In 1967, the Clean Air Act of Texas was superseded by a more 

comprehensive statute, the Texas Clean Air Act (TCAA), found in Article 4477-5, Vernon's Texas 

Civil Statutes. The legislature amended the TCAA in 1969, 1971, 1973, 1979, 1985, 1987, 1989, 

1991, 1993, 1995, 1997, 1999, 2001, 2003, 2005, 2007, 2009, and 2011. In 1989, the TCAA was 

codified as Chapter 382 of the Texas Health and Safety Code. 

Originally, the TCAA stated that the Texas Air Control Board (TACB) is the state air pollution 

control agency and is the principal authority in: the state on matters relating to the quality of air 

resources. In 1991, the legislature abolished the TACB effective September 1, 1993, and its 

powers, duties, responsibilities, and functions were transferred to the Texas Natural Resource 

Conservation Commission (TNRCC). With the creation of the TNRCC, the authority over air 

quality is found in both the Texas Water Code and the TCAA. Specifically, the authority of the 

TNRCC is found in Chapters 5 and 7· Chapter 5, Subchapters A- F, H- J, and L, include the 

general provisions, organization, and general powers and duties of the TNRCC, and the 

responsibilities and authority of the executive director. Chapter 5 also authorizes the TNRCC to 

implement action when emergency conditions arise and to conduct hearings. Chapter 7 gives the 

TNRCC enforcement authority. In 2001, the 77th Texas Legislature continued the existence of 

the TNRCC until September 1, 2013, and changed the name of the TNRCC to the TCEQ. In 

2009, the 81st Texas Legislature, during a special session, amended section 5.014 of the Texas 

Water Code, changing the expiration date of the TCEQ to September 1, 2011, unless continued in 

existence by the Texas Sunset Act. In 2011, the 82nd Texas Legislature continued the existence 

of the TCEQ until 2023. 

The TCAA specifically authorizes the TCEQ to establish the level of quality to be maintained in 

the state's air and to control the quality of the state's air by preparing and developing a general, 

comprehensive plan. The TCAA, Subchapters A-D, also authorize the TCEQ to collect 

information to enable the commission to develop an inventory of emissions; to conduct research 

and investigations; to enter property and examine records; to prescribe monitoring 

requirements; to institute enforcement proceedings; to enter into contracts and execute 

instruments; to formulate rules; to issue orders taking into consideration factors bearing upon 

health, welfare, social and economic factors, and practicability and reasonableness; to conduct 

hearings; to establish air quality control regions; to encourage cooperation with citizens' groups 

and other agencies and political subdivisions of the state as well as with industries and the 

federal government; and to establish and operate a system of permits for construction or 

modification of facilities. 

Local government authority is found in Subchapter E of the TCAA. Local governments have the 

same power as the TCEQ to enter property and make inspections. They also may make 

recommendations to the commission concerning any action of the TCEQ that affects their 

territorial jurisdiction, may bring enforcement actions, and may execute cooperative agreements 

with the TCEQ or other local governments. In addition, a city or town may enact and enforce 

ordinances for the control and abatement of air pollution not inconsistent with the provisions of 

the TCAA and the rules or orders of the commission. 
Subchapters G and H of the TCAA authorize the TCEQ to establish vehicle inspection and 

maintenance programs in certain areas of the state, consistent with the requirements of the 

Federal Clean Air Act; coordinate with federal, state, and local transportation planning agencies 

to develop and implement transportation programs and measures necessary to attain and 

maintain the NAAQS; establish gasoline volatility and low emission diesel standards; and fund 

and authorize participating counties to implement vehicle repair assistance, retrofit, and 

accelerated vehicle retirement programs. 

Applicable Law 

The following statutes and rules provide necessary authority to adopt and implement the state 

implementation plan (SIP). The rules listed below have previously been submitted as part of the 

SIP.

CHAPTER1: GENERAL(UPDATED) 

1.1 BACKGROUND AND INTRODUCTION (UPDATED) 

1.1.1 Purpose of Plan (Updated) 

In 2008, the commission adopted the Eight-Hour Ozone Redesignation Request and 

Maintenance Plan for the Beaumont-Port Arthur (BPA) Ozone Nonattainment Area (Project No. 

2008-oo6-SIP-NR), which fulfills all Federal Clean Air Act (FCAA) requirements to redesignate 

the BPA ozone nonattainment area (Hardin, Jefferson, and Orange Counties) to attainment of 

the 1997 eight-hour ozone standard and demonstrates continued attainment of that standard 

through 2021. The plan was approved by the United States Environmental Protection Agency 

(EPA), effective November 19, 2010, and the BPA area was redesignated to attainment for the 

1997 eight-hour ozone standard. The maintenance plan contains on-road mobile emissions 

inventories, a nitrogen oxides (NOx) motor vehicle emissions budget (MVEB), and a volatile 

organic compounds (VOC) MVEB developed using the EPA's MOBILE emissions estimation 

model. On March 2, 2010, the EPA officially released a new model, the Motor Vehicle Emission 

Simulator (MOVES) model, to replace the MOBILE model for SIP applications. 

Beginning March 2, 2013, transportation conformity must be conducted using the MOVES 

model. To demonstrate transportation conformity, a nonattainment or maintenance area must 

show that its metropolitan transportation plans, transportation improvement programs, and 

projects funded by the Federal Highway Administration or the Federal Transit Administration 

conform to the MVEBs established in the state implementation plan (SIP). Conformity must be 

demonstrated before area transportation plans can be approved or funded by the United States 

Depa,rtment of Transportation or the Metropolitan Planning Organizations. Updating MVEBs 

using MOVES-based on-road mobile emissions inventories requires a SIP revision. This 

proposed SIP revision would facilitate future MOVES-based transportation conformity 

determinations by providing MVEBs based on the latest version of the MOVES model, 

MOVES2o10a. 

This proposed SIP revision would replace the 2008 BPA maintenance plan on-road mobile 

source emissions inventories for NOx and VOC based on the EPA's MOBILE model with those 

based on the EPA's MOVES model. On-road mobile source emissions inventory updates include 

those for 2005, 2011, 2014, 2017, and 2021. In addition, 2021 NOx and VOC MVEBs would be 

updated according to the MOVES-based emissions inventories. 

This proposed SIP revision includes documentation to satisfy the EPA's MOVES 

implementation policy guidance 2 concerning updating maintenance plans with MOVES, which 

indicates that states must (1) demonstrate that the updated plan continues to meet all 

maintenance requirements and (2) document that growth and control strategy assumptions for 

all other source categories (area, non-road mobile, and stationary point) continue to be valid 

and any minor updates would not change the conclusions of the approved maintenance plan.

Transportation Conformity, and Other Purposes." Transportation and Regional Programs Division, Office 

of Transportation and Air Quality, U.S. Environmental Protection Agency, EPA-420-B-09-046, December

1.1.3 Eight-Hour Ozone History in the BPAArea (Updated) 

1.1.3.1 2008 and 2010 Eight-Hour Ozone Standards (Added) 

On March 12, 2008, the EPA lowered the primary and secondary eight-hour ozone standards to 

0.075 parts per million (ppm). The governor recommended to the EPA in March 2009 that 

Hardin, Jefferson, and Orange Counties be designated as a nonattainment area for the 2008 

eight-hour ozone standard. In September 2009, the EPA announced that it intended to 

reconsider the 2008 ozone standard. On January 19, 2010, the EPA proposed revisions in the 

Federal Register (75 FR 2938) to strengthen the primary eight-hour ozone standard in the 

range of o.o6o to 0.070 ppm. On September 2, 2011, the President announced a request that the 

EPA withdraw the proposed, reconsidered ozone standard. 

In a September 2011 memo, the EPA announced that it would proceed with initial area 

designations under the 2008 (0.075 ppm) eight-hour ozone standard, starting with the 

recommendations states made in 2009 and updating those recommendations with the most 

current, certified air quality data (2008 through 2010). The governor submitted a revised 

designation recommendation in October 2011 that excluded Hardin, Jefferson, and Orange 

Counties from being designated as nonattainment under the reinstated 2008 eight-hour ozone 

standard. 

The EPA published final designations for the 2008 ozone standard along with a final rulemaking 

to revoke transportation conformity under the 1997 eight-hour ozone standard on May 21, 2012. 

Since the BPA area is designated attainmentjunclassifiable for the 2008 eight-hour ozone 

standard and is a maintenance area for the 1997 eight-hour ozone standard, transportation 

conformity will no longer be required upon the effective date of revocation of transportation 

conformity for the 1997 eight-hour ozone standard, July 20, 2013. 

1.2 PUBLIC HEARING INFORMATION (UPDATED) 

The commission will offer a public hearing in Beaumont on August 1, 2012, at six o'clock in the 

evening. The public hearing will be held in the Homer E. Nagel Conference Room of the South 

East Texas Regional Planning Commission at 2210 Eastex Freeway, Beaumont, Texas 77703. 

The public comment period will open on June 29, 2012, and will close on August 3, 2012. Notice 

of public hearing for this SIP revision will be published in the Texas Register and the 

"Beaumont Enterprise" newspaper. Written comments will be accepted via mail, fax, or through 

the eComments system. All comments should reference the "Beaumont-Port Arthur Attainment 

Area On-Road Mobile Source Emissions Inventory and Motor Vehicle Emissions Budget Update

2.1 ATTAINMENT OF THE 1997 EIGHT-HOUR OZONE NATIONAL AMBIENT AIR 

QUALITY STANDARD (UPDATED) 

2.1.1 Ozone Data (No Change) 

2.1.2 Ozone Trend Analysis (Updated) 

Ozone trends in the Beaumont-Port Arthur (BPA) area have been decreasing over the past 20 

years. Figure 2-1: Ozone Design Value Trends in the BPAArea shows decreases in both the 

eight-hour and one-hour ozone design values. Although both the eight-hour and the one-hour 

design values increased from 2010 to 2011, the overall design value trend has been decreasing. 

The eight-hour ozone design value has decreased by 22% over the past 20 years and the onehour ozone design value had decreased by 27% over the past 20 years. The 2011 eight-hour 

ozone design value for the BPA area was 79 parts per billion (ppb), which is below the 1997 

eight-hour ozone standard of 84 ppb (o.o8 parts per million (ppm)). The BPA area has not 

exceeded the eight-hour ozone standard since 2006. The 2011 one-hour ozone design value for 

the BPA area was 110 ppb, which is also below the revoked one-hour ozone standard of 125 ppb 

( 0.12 ppm). The decreases in ozone have occurred despite increases in population in the BPA 

area, as shown in Figure 2-2: Ozone Design Values and Population Trends in the BPAArea. 

Figure 2-3: Ozone Exceedance Days and Number of Monitors in the BPA Area shows that the 

number of eight-hour ozone exceedance days has decreased in the BPA area despite an increase 

in the number of monitors. Although there were more eight-hour ozone exceedance days in 2011 

compared to 2010, the overall trend in exceedance days is decreasing. There were only four 

eight-hour ozone exceedance days in the BPA area in 2011, an unusual year with recordbreaking temperatures and an unusual number of days that favored the development of ozone. 

Because the exceedance day count is dependent on the number of monitors in the area, the 

number of eight-hour ozone exceedance days by monitor is shown in Figure 2-4: Eight-Hour 

Ozone Exceedance Days by Monitor in the BPAArea. Exceedances by monitor tend to vary 

from year to year; however, the overall trend in the number of eight-hour ozone exceedance days 

has been decreasing over the past 20 years.

Downtown (CAMS 2/CAMS 112/ CAMS 2002), Jefferson County Airport (CAMS 

1019/CAMS2001), Hamshire (CAMS 64/CAMS 654), Nederland High School (CAMS 1035), and 

West Orange (CAMS 9/CAMS141). Data for 2011 cover only the first two quarters of the year, 

and NOx averages during 2011 are subject to change. The average NOx concentration has 

remained relatively flat at most monitors until sometime from 2003 to 2006. After 2006, the 

last year the BPA area had an ozone design value exceed 84 ppb, most monitors showed a large 

decrease in NOx concentrations. West Orange (CAMS 9/CAMS141) did show a slight increase in 

average NOx concentrations from 2010 to 2011, but the overall trend from 1991 to 2011 shows a 

decrease of 54%. NOx decreased 26% from 1991 to 2011 at the Beaumont Downtown (CAMS 

2/CAMS 112/ CAMS 2002) site, 40% from 2000 to 2011 at the Hamshire (CAMS 64/CAMS 654) 

site, and so% from 2006 to 2011 at the Nederland High School (CAMS 1035) site.

Volatile Organic Compounds Trends (Updated) 

Continuous volatile organic compounds (VOC) data are collected at two automated gas 

chromatograph (AutoGC) monitors in the BP A area. Those two monitors are Beaumont 

Downtown (CAMS 2/CAMS 112/ CAMS 2002) and Nederland High School (CAMS 1035), which 

have valid data beginning August 28, 2006, and August 29, 2006, respectively, and ending on 

December 1, 2011. Note that the last month of data from 2011 is not yet available. Figures 2-6: 

Median Ethylene at AutoGCs in the BPA Area and 2-7: Median Propylene at AutoGCs in the 

BPA Area show the median ethylene and propylene concentrations at the two AutoGC monitors 

in the BPA area, respectively. Both ethylene and propylene have decreased at all monitors over 

the last five years. Ethylene decreased 55% at Beaumont Downtown (CAMS 2/CAMS 112/ CAMS 

2002) and 41% at Nederland High School (CAMS 1035). Propylene decreased 54% at Beaumont 

Downtown (CAMS 2/CAMS 112/ CAMS 2002) and 35% at Nederland High School (CAMS

VOC canister data have also been available in the BPA area since 1994. The VOC canisters 

samples are 24-hour averages and are sampled every 6 days. Figures 2-8: Median Ethylene 

Trends from Canister Data in the BPAArea and 2-9: Median Propylene Trends from Canister 

Data in the BPA Area both show that ethylene and propylene, two of the most reactive VOC, 

have been decreasing at nine canister sites in the BPA area over the past 14 and 17 years, 

respectively. Only one quarter of data are available for 2011, so concentrations are subject to 

change. While the ethylene concentrations are generally higher than the propylene 

concentrations, the median ethylene concentrations have decreased at the nine canister sites 

(one of the eight sites has three monitors), with an average decrease of 41%. West Orange 

(CAMS 9/CAMS141) and Beaumont Mary (CAMS 1050) both showed increases in ethylene; 

however, the West Orange (CAMS 9/CAMS141) canister site stopped operation in 2006, and the 

Beaumont Mary (CAMS 1050) site has only been in operation for two years. Similarly, median 

propylene concentrations have decreased at the nine canister sites, with an average decrease of 

42%. Again, the Beaumont Mary (CAMS 1050) site showed a slight increase in propylene 

concentrations, but it has only been in operation for two years. For both propylene and ethylene, 

the increase at Beaumont Mary (CAMS 1050) was less than 0.5 ppb.

CHAPTER 4: MAINTENANCE DEMONSTRATION (UPDATED) 

4.1 GENERAL (UPDATED) 

This proposed state implementation plan (SIP) revision is an update to the 2008 BeaumontPortArthur (BPA) maintenance plan that revises the original on-road mobile source emissions 

inventories, nitrogen oxides (NOx) motor vehicle emissions budget (MVEB), and volatile organic 

compounds (VOC) MVEB to be based on the United States Environmental Protection Agency's 

(EPA) Motor Vehicle Emission Simulator (MOVES) model. The on-road mobile source 

emissions inventories and MVEBs adopted with the 2008 BP A maintenance plan, which was 

approved by the EPA effective November 19, 2010, were developed using the MOBILE emissions 

estimation model. On March 2, 2010, the EPA officially released the MOVES model to replace 

the MOBILE model for SIP applications. Beginning March 2, 2013, transportation conformity 

must be conducted using the MOVES model. This proposed update to the 2008 BPA 

maintenance plan would facilitate future, required, MOVES-based transportation conformity 

determinations. 

The EPA provided a guidance documene to assist states in incorporating MOVES-based onroad mobile source emissions inventories and MVEBs into existing area maintenance plans. The 

guidance allows states, under stipulated conditions, to update only the on-road mobile source 

portions of their maintenance plans. States must (1) demonstrate that the updated plan 

continues to meet all maintenance requirements and (2) document that growth and control 

strategy assumptions for all other source categories (area, non-road mobile, and stationary 

point) continue to be valid and any minor updates would not change the conclusions of the 

approved maintenance plan. 

This proposed SIP revision satisfies both conditions of the MOVES guidance document; 

therefore, only Section 4-4.2: On-Road Mobile Sources has been revised. For each of the other 

source categories (area, non-road mobile, and stationary point), sections have been added 

describing that any minor updates have not changed the conclusions of the 2008 BPA 

maintenance plan: Section 4.2.1.2: Updated Verification ofContinuedAttainmentfor Area 

Sources; Section 4.2.3.3: Updated Verification ofContinuedAttainmentfor Non-Road Mobile 

Sources; and Section 4.244: Updated Verification ofContinuedAttainmentfor Stationary 

Point Sources. 

4.2 FUTURE EMISSIONS AND VERIFICATION OF CONTINUED ATTAINMENT 

(UPDATED) 

MOVES-based on-road mobile source NOx and VOC emissions estimates would change slightly 

from the MOBILE-based estimates adopted with the 2008 BPA maintenance plan. Table 4-1: 

MOBILE-Based On-Road Mobile Source NOx and VOC Emissions in the BPA Area (2005, 2011, 

2014, 2017, and 2021) summarizes, in tons per day (tpd), the on-road mobile source emissions 

estimates (MOBILE-based) that were included in the original maintenance plan. Emissions 

estimates for area, non-road mobile, and stationary point sources were not included in Table 4-1 

because they were not updated from the 2008 BPA maintenance plan. MOVES-based NOx and 

VOC on-road mobile source emission estimates are summarized in Tables 4-2: Updated 

Summary ofNOx Emissions in BPA by Source Type (2005, 2011,2014,2017, and 2021) and 4-

and stationary point). Tables 4-2 and 4-3 show how this proposed update to the MOVES model 

would affect the projected overall emissions trends included in the 2008 BPA maintenance plan.

The 2008 BPA maintenance plan demonstrates that overall NOx emissions are projected to 

decline by 15.36 tpd from 2005 through 2021 using MOBILE-based on-road emissions 

estimates. Updating the BPA maintenance plan to incorporate the MOVES model would still 

result in a decline in projected NOx emissions; however, the decline would be slightly smaller, 

10.80 tpd. The original maintenance plan (MOBILE-based) demonstrated an increase in overall 

VOC emissions projections from 2005 through 2021, 12.72 tpd. While MOVES-based 

projections also show an increase in overall VOC emissions, that increase is smaller, 12.18 tpd. 

Although there is a slight estimated increase in VOC over the 16 years projected for the BPA 

maintenance plan, it has been established that NOx emissions reductions are more effective 

than VOC reductions at reducing ozone design values in the BPA area. In fact, photochemical 

modeling analysis adopted with the 2008 BPA maintenance plan showed that reductions in NOx 

emissions are 3.76 times as effective as VOC reductions at reducing the BPA-area ozone design 

value. In its proposed approval of the 2008 plan in the Federal Register (75 FR 27514), the EPA 

supported the 2008 demonstration by stating that "based on photochemical modeling analyses 

showing that the formation of ozone in the BPA area is more sensitive to NOx than to VOC 

emissions, the increase in VOC emissions is expected to be fully offset by the decrease in NOx." 

4-3 
Based on the photochemical modeling analysis included in the original 2008 BPA maintenance 

plan and supported by the EPA, emissions in the BP A area are expected to remain at levels 

consistent with attainment for the 1997 eight-hour ozone standard through 2021. Please see 

Section 4.2: Future Emissions and Verification of Continued Attainment of the original 2008 

BPA maintenance plan for further details on the photochemical modeling analysis 

demonstrating the effectiveness of NOx in reducing ozone design values in the BP A area. 

4.2.1 Area Sources (Updated) 

4.2.1.1 Flash Emissions from Upstream Oil and Gas Production (No Change) 

4.2.1.2 Updated Verification of Continued Attainment for Area Sources (Added) 

In reviewing the 2008 BP A maintenance plan and applying updates, staff determined that 

emissions would be further decreased for both NOx and VOC. There are two factors attributed to 

these reductions: updated growth factors provided by the Eastern Research Group through a 

contract in 2010; 4 and speciation updates performed on the oil and gas categories for 2005. 

Although minor updates have occurred in the area source category since the 2008 submission, 

those updates do not change the overall conclusions of the BP A maintenance plan SIP revision. 

4.2.2 On-Road Mobile Sources (Updated) 

The Texas Commission on Environmental Quality (TCEQ) updated the 2008 BP A maintenance 

plan's on-road mobile source emissions inventory estimates for this proposed SIP revision by 

contracting with the Texas Transportation Institute (TTI). TTl developed detailed, hourly, linkbased ozone season weekday emissions estimates for the three BPA counties, Jefferson, Hardin, 

and Orange, using the newest version of the EPA's MOVES model, MOVES2010a. The updated 

emissions inventory estimates include NOx and VOC emissions for the 2005 base year for the 

2011, 2014, and 2017 interim years and for the 2021 horizon year. TTl also used the latest 

planning assumptions to develop the maintenance inventories in an effort to ensure that the 

MVEBs would be consistent with transportation conformity analysis assumptions. 

TTl produced emissions estimates using a link-based methodology that used a travel demand 

model (TDM) and MOVES "rates-per-activity." Emissions were estimated by hourly and 24-

hour periods by MOVES source use type and fuel type, pollutant process, and TDM roadway 

class. The most recently available data were used, including Texas Department of 

Transportation (TxDOT) vehicle classification counts and TxDOT /Texas Department of Motor 

Vehicles registration data. MOVES default data were used as needed. Control programs that 

were modeled in the analysis include: 

• Federal Motor Vehicle Control Program Standards; 

• Federal Low Emissions Heavy-Duty Diesel Engines Rebuild Program; 

• Federal Heavy-Duty 2004 Pull-Ahead Program; 

• Conventional Gasoline with Federal Low Reid Vapor Pressure; and 

• Diesel Fuel with Texas Low Emission Diesel as appropriate for applicable years. 

For the fuel programs, MOVES defaults, fuel survey data, and federally regulated values were 

used. Details of how these were modeled are found in Appendix D: BPA Area On-Road 

Emissions Inventories for SIP Submission- 2005, 2011,2014,2017, and 2021, TTI Report,

4.2.2.1 Motor Vehicle Emissions Budgets (Updated) 

The 2008 BPA maintenance plan established MOBILE-based MVEBs, setting the allowable onroad mobile emissions that an area can produce while continuing to demonstrate maintenance. 

Local transportation planning organizations demonstrate that projected emissions from 

transportation plans, programs, and projects are equal to or less than the MVEBs as required by 

the federal transportation conformity rule. The NOx and VOC on-road mobile source emissions 

inventory totals for 2021, the final year of this maintenance plan, establish the MVEBs. The 

MOVES-based MVEBs for this proposed SIP revision are summarized in Table 4-7: 2021 

Horizon Year MVEBsfor the BPA area using MOVES2010a. Detailed documentation ofMVEB 

calculations, modeling methods, and input parameter development and usage is provided in

4.2.3.1 Airports (No Change) 

4.2.3.2 Locomotives and Marine Vessels (No Change) 

4.2.3.3 Updated Verification of Continued Attainment for Non-Road Mobile Sources (Added) 

NONROAD Model 

For all Texas non-road mobile source categories except aircraft, airport equipment, locomotives, 

and commercial marine vessels, emissions are calculated using the Texas-Specific NONROAD 

4-5 
(TexN) model that utilizes the EPA's latest NONROAD model. While the TexN model utilizes 

input files and post-processing routines to estimate Texas specific emissions estimates, it retains 

the EPA's NONROAD model as the core model to conduct the basic emissions calculations. 

The EPA's NONROAD2005 model, which was used as the core model for the 2008 BPA 

maintenance plan, was updated to the NONROAD2oo8a version in April 2009. The 

NONROAD2oo8a model accounted for the addition of two new federal rules that affect the 

equipment categories in the non-road mobile source sector; therefore, the TexN model was 

updated accordingly. In addition, equipment survey studies have been conducted and emissions 

updated for the diesel construction equipment sector, the agricultural equipment sector, and 

drilling rig diesel engines since 2009. 

Using current methodology and the TexN/EPA NONROAD2oo8a model, emissions calculated 

for each county in the BP A area are, overall, lower and demonstrate a downward trend for both 

NOx and VOC compared to the emissions reported in the 2008 BPA maintenance plan. 

Although minor updates have occurred in the non-road mobile source category since the 2008 

submission, those updates do not change the overall conclusions of the BP A maintenance plan. 

Airports 

The Federal Aviation Administration's Emissions and Dispersion Modeling System (EDMS) 

version 5.1 was used to estimate NOx and VOC emissions for commercial aircraft, general 

aviation, and ground support equipment emissions in the 2008 BPA maintenance plan. The 

model has not changed since the 2008 submission, and the repopulated EDMS files, which 

reflect 2011 operations, indicate that both" NOx and VOC emissions declined between 2005 and 

2011. 

The 2011 emissions calculated for the airports source category in the BP A area demonstrate a 

downward trend for both NOx and VOC compared to the emissions reported in the 2008 BPA 

maintenance plan. Although minor updates have occurred in the airports source category since 

the 2008 submission, those updates do not change the overall conclusions of the BPA 

maintenance plan. 

Locomotives and Commercial Marine Vessels 

Texas Air Emissions Repository (TexAER) data from 2005, which was developed from the 2005 

Consolidated Emissions Reporting Rule data, were used to estimate NOx and VOC emissions 

from locomotive and commercial marine vessel activities in the 2008 BPA maintenance plan. 

The methodology has not changed since the 2008 submission. 

Actual 2011 emissions calculated for locomotive and commercial marine vessel activities in the 

BPA area, when compared to the projected 2011 emissions reported in the 2008 BPA 

maintenance plan, are lower and demonstrate a downward trend for both NOx and VOC. Since 

the original inventories conservatively estimated future year locomotive and commercial marine 

vessel activities emissions, recalculation of the milestone year inventories would not change the 

overall conclusions of the 2008 BPA maintenance plan.

4.2.4.3 Updated Uncontrolled Milestone Year Inventories (No Change) 

4.2.4.4 Updated Verification of Continued Attainment for Stationary Point Sources (Added) 

There have been no changes to the point source emissions inventories included in the 2008 BPA 

maintenance plan. Those inventories projected positive point source emissions growth for all 

future milestone years. Actual point source emissions for 2008 through 2010 are below the 

2005 base year emissions, below emissions trends projected in the maintenance plan, and are 

anticipated to remain below projected emissions. Since the original inventories conservatively 

estimated future year point source emissions, recalculation of the milestone year inventories 

would not change the overall conclusions of the 2008 BPA maintenance plan. 

4·3 CONTROL STRATEGIES (NO CHANGE) 

4·4 EMISSIONS SUMMARY (UPDATED) 

Updated percentages of emissions by source category for 2005, 2011, 2014, 2017, and 2021 are 

reflected in Tables 4-8: Updated Percentages ofNOx Emissions in BPA by Source Category and 

4-9: Updated Percentages ofVOCEmissions in BPA by Source Category. The percentages of 

contribution from source categories have changed slightly with the MOVES-based on-road 

mobile source emissions inventory updates. Table 4-8 shows that on-road mobile source 

emissions determined using the MOVES model account for a slightly larger percentage of NOx 

emissions, overall, than those determined using the MOBILE model. Table 4-9 shows that onroad mobile source emissions determined using the MOVES model account for a slightly smaller 

percentage ofVOC emissions, overall, than those determined using the MOBILE model. As in 

the 2008 BPA maintenance plan, these tables show that the largest man-made contribution of 

NOx is from stationary point sources and the largest man-made contribution ofVOC is from 

area sources. Contributions from biogenic emissions are not included in the summary, because 

the maintenance measures are limited to the reduction of man-made emissions.

4·5 CONTINUED MAINTENANCE WITH MOVES-BASED ON-ROAD MOBILE 

EMISSIONS INVENTORIES (ADDED) 

Revising the on-road mobile source emissions inventories and MVEBs for this proposed SIP 

revision would minimally affect projected NOx and VOC emissions trends from the 2005 base 

year across the 2011, 2014, and 2017 milestone years and the 2021 horizon year; however, NOx 

emissions are still projected to decrease and VOC emissions are still projected to increase (see 

Tables 4-2 and 4-3). On-road mobile source emissions inventories were the only inventories 

updated; however, in determining whether to update inventories for the other source categories, 

TCEQ staff found that area, non-road mobile, and stationary point source emissions all trended 

below the projections included in the 2008 BP A maintenance plan. In addition, photochemical 

modeling analyses adopted with the 2008 BPA maintenance plan and supported by the EPA 

demonstrate that the formation of ozone in the BPA area is more sensitive to NOx than to VOC 

emissions. The slight increase in VOC emissions, which was shown in the original BPA 

maintenance plan as well as this proposed update, would be offset by the decrease in NOx 

emissions. Those factors, along with the overall downward trend in ozone design values for the 

BP A area, show that this proposed SIP revision would continue to meet all requirements for 

maintenance of the 1997 eight-hour ozone standard.

Docket No.: 2012-o8os-SIP 

Subject: Commission Approval for Adoption of the Beaumont-Port Arthur (BP A) 

Attainment Area On-Road Mobile Source Emissions Inventory and Motor 

Vehicle Emissions Budget (MVEB) Update State Implementation Plan (SIP) 

Revision 

BP A MVEB Update SIP Revision 

SIP Project No. 2012-005-SIP-NR 

Background and reason(s) for the SIP revision: 

In 2008, the commission adopted the BPA area maintenance plan (Project No. 2008-oo6-

SIP-NR), which demonstrates continued attainment of the 1997 eight-hour ozone standard 

through 2021. The plan was approved by the United States Environmental Protection 

Agency (EPA) effective November 19, 2010, and the BPA area was redesignated to 

attainment for the 1997 eight-hour ozone standard. The maintenance plan contains onroad mobile emissions inventories developed using the EPA's MOBILE (MOBILE6.2) 

emissions estimation model. On March 2, 2010, the EPA officially released the Motor 

Vehicle Emission Simulator (MOVES) model, to replace the MOBILE model for SIP 

applications. Beginning March 2, 2013, transportation conformity must be conducted by 

all local metropolitan planning organizations (MPO) using the MOVES model. 

On September 9, 2011, the Texas Commission on Environmental Quality (TCEQ) received 

a letter from the South East Texas Regional Planning Commission, the BPA-area MPO, 

requesting the development of MOVES-based MVEBs to replace the existing MOBILEbased MVEBs. The letter indicated that the area was unable to conform to the existing 

MVEBs and would enter into a conformity lapse on September 25, 2012, which it has. The 

conformity lapse entails the cessation of new transportation projects and project phases 

until the area is able to conform to EPA-approved MVEBs. This SIP revision responds to 

the MPO's request by establishing new MVEBs to which the BPA transportation plan may 

be able to conform. 

Scope of the SIP revision: 

A.) Summary of what the SIP revision will do: 

This SIP revision replaces the 2008 BPA maintenance plan on-road mobile source 

emissions inventories for nitrogen oxides (NOx) and volatile organic compounds (VOC) 

based on the EPA's MOBILE model with those based on the EPA's MOVES model, 

specifically MOVES2010a. On-road mobile source emissions inventory updates include 
Commissioners 

Page2 

October 26, 2012 

Re: Docket No. 2012-0805-SIP 

those for 2005, 2011, 2014, 2017, and 2021. The 2021 NOx and VOC MVEBs are also 

updated based on the MOVES-based emissions inventories. 

This SIP revision includes documentation to satisfy the EPA's MOVES implementation 

policy guidance 1 concerning updating maintenance plans with MOVES, which indicates 

that states must (1) demonstrate that the updated plan continues to meet all maintenance 

requirements and (2) document that growth and control strategy assumptions for all other 

source categories (area, non-road mobile, and stationary point) continue to be valid and 

any minor updates would not change the conclusions of the approved maintenance plan. 

B.) Scope required by federal regulations or state statutes: 

For maintenance plans, MVEBs set the maximum level of on-road mobile transportation 

emissions that can be produced when considered with emissions from all other sources, 

which demonstrates continued maintenance of the National Ambient Air Quality 

Standards (NAAQS). Maintenance plans must include MVEBs for transportation 

conformity purposes. Transportation conformity is required by Federal Clean Air Act 

(FCAA), §176(c) to ensure that the effects of emissions from all on-road sources are 

consistent with attainment or maintenance of any criteria pollutant or its precursors 

allocated to highway and transit vehicle use. Conforming to the SIP means that 

transportation activities will not cause new air quality violations, worsen existing 

violations, or hinder maintenance of the NAAQS. The EPA's conformity rule, 40 Code of 

Federal Regulations Part 51.390 and Part 93 Subpart A, states that "conformity 

determinations must be based on the latest emission estimation model available." 

C.) Additional staff recommendations that are not required by federal rule or 

state statute: 

On June 28, 2012, the TCEQ sent a letter to EPA, Region 6 requesting that the EPA parallel 

process its review and approval of this SIP revision with the TCEQ's. The EPA will consider 

a request to parallel process only when the state anticipates that there will be no significant 

changes made to the associated SIP revision between proposal and adoption because a 

notice of proposed approval from the EPA could potentially be published before the state 

adopts the SIP revision. With parallel processing, the EPA's proposed approval is based on 

the state's proposed SIP revision. No significant changes were made to the BP A MVEB 

Update SIP Revision from the proposed version that was sent to the EPA along with the 

request to parallel process, and consequently, the EPA published its proposed approval in 

the Federal Register on September 19, 2012 (77 FR 58058). 

The parallel processing request was made to allow BP A-area transportation partners to 

conduct a conformity determination using EPA-approved, MOVES-based MVEBs as 

quickly as possible due to the transportation conformity lapse that began September 25, 

1 EPA, 2009. "Policy Guidance on the Use ofMOVES2010 for State Implementation Plan Development, 

Transportation Conformity, and Other Purposes." Transportation and Regional Programs Division, Office of 

Transportation and Air Quality, U.S. Environmental Protection Agency, EPA-420-B-09-046, December 

2009.

Re: Docket No. 2012-0805-SIP 

2012. Although this SIP revision and the EPA's expedited approval of it could not prevent 

the transportation conformity lapse from occurring, these actions by the commission and 

the EPA may help minimize the consequences of the lapse by shortening its duration. 

Statutory authority: 

The authority to propose and adopt the SIP revision is derived from the FCAA, 42 United 

States Code, §7410, which requires states to submit SIP revisions that contain enforceable 

measures to achieve the NAAQS and other general and specific authority in Texas Water 

Code, Chapters 5 and 7 and Texas Health and Safety Code, Chapter 382. 

Effect on the: 

A.) Regulated community: 

The local transportation planning entities may benefit from MOVES-based MVEBs by 

being able to proceed with planning and initiating congestion-reducing transportation 

projects. 

B.) Public: 

The general public could benefit from transportation improvement projects that decrease 

traffic congestion and emissions. 

C.) Agency programs: 

This SIP revision has no new effect on agency programs. 

Stakeholder meetings: 

No stakeholder meetings were held because there were no new rules associated with this 

SIP revision. 

Public comment: 

The commission offered a public hearing in Beaumont on August 1, 2012. Notice of the 

public hearing was published in the Texas Register and the Beaumont Enterprise 

newspaper. The public hearing was not opened because no one signed in to provide oral 

testimony. The public comment period opened on June 29, 2012, and closed on August 3, 

2012. No written comments were received concerning this SIP revision. 

Significant changes from proposal: 

No significant changes were made to this SIP revision after proposal. 

Potential controversial concerns and legislative interest: 

The transportation plan for the BP A area lapsed starting September 25, 2012, which means 

that no new projects or project phases may advance until the area is able to conform to 

EPA-approved MVEBs. This SIP revision may or may not help that problem as the BPA 

transportation plan may not be able to conform to MOVES-based MVEBs either. That 

would leave the area in a continued transportation conformity lapse until it adopts a new

Re: Docket No. 2012-0805-SIP 

transportation plan after the effective date of revocation of transportation conformity 

requirements under the 1997 eight-hour ozone standard, July 20, 2013. 

With revocation of transportation conformity requirements under the 1997 standard and 

with an attainment/unclassifiable designation under the 2008 standard, the BPA area 

would no longer be required to demonstrate transportation conformity. This SIP revision 

may only be useful, then, if the EPA finalizes approval and the area demonstrates 

conformity before July 20, 2013. The TCEQ formally requested that the EPA parallel 

process its review and approval of this SIP revision to make it possible for the area to 

demonstrate conformity to MOVES-based, EPA-approved MVEBs as soon after 

commission adoption as possible and before July 20, 2013. That request was made on June 

28, 2012, and the EPA published its proposed approval in the Federal Register on 

September 19, 2012 (77 FR 58058). 

Does this SIP revision affect any current policies or require development of 

new policies? 

No 

What are the consequences if this SIP revision does not go forward? Are there 

alternatives to this SIP revision? 

The BP A-area transportation plan lapsed on September 25, 2012, after which no new 

transportation projects or project phases have been allowed to advance. If the area is not 

able to conform to the existing maintenance MVEBs, transportation projects could be on 

hold until the area adopts a new transportation plan after the effective date of revocation of 

transportation conformity requirements under the 1997 eight-hour ozone standard, which 

is expected July 20, 2013.

EXECUTIVE SUMMARY 

In 2008, the commission adopted the Eight-Hour Ozone Redesignation Request and 

Maintenance Plan for the Beaumont-Port Arthur (BPA) Ozone Nonattainment Area (Project No. 

2oo8-oo6-SIP-NR), which fulfills all Federal Clean Air Act (FCAA) requirements to redesignate 

the BP A ozone nonattainment area (Hardin, Jefferson, and Orange Counties) to attainment of 

the 1997 eight-hour ozone standard and demonstrates continued attainment of that standard 

through 2021. The plan was approved by the United States Environmental Protection Agency 

(EPA) effective November 19, 2010, and the BPA area was redesignated to attainment for the 

1997 eight-hour ozone standard. The maintenance plan includes on-road mobile emissions 

inventories and nitrogen oxides (NOx) and volatile organic compounds (VOC) motor vehicle 

emissions budgets (MVEBs) developed using the EPA's MOBILE emissions estimation model. 

On March 2, 2010, the EPA officially released a new model, the Motor Vehicle Emission 

Simulator (MOVES) model, to replace the MOBILE model for SIP applications. 

Beginning March 2, 2013, transportation conformity must be conducted using the MOVES 

model. To demonstrate transportation conformity, a nonattainment or maintenance area must 

show that its metropolitan transportation plans, transportation improvement programs, and 

projects funded by the Federal Highway Administration or the Federal Transit Administration 

conform to the MVEBs established in the state implementation plan (SIP). Conformity must be 

demonstrated before area transportation plans can be approved or funded by the United States 

Department of Transportation or the metropolitan planning organizations. Updating MVEBs 

using MOVES-based on-road mobile emissions inventories requires a SIP revision. This SIP 

revision will facilitate future MOVES-based transportation conformity determinations by 

providing MVEBs based on the MOVES2010a model. 

This SIP revision replaces the 2008 BPA maintenance plan on-road mobile source emissions 

inventories for NOx and VOC based on the EPA's MOBILE model with those based on the EPA's 

MOVES model. On-road mobile source emissions inventory updates include those for 2005, 

2011, 2014, 2017, and 2021. In addition, 2021 NOx and VOC MVEBs are updated based on the 

MOVES-based emissions inventories. 

This SIP revision includes documentation to satisfy the EPA's MOVES implementation policy 

guidance 1 concerning updating maintenance plans with MOVES, which indicates that states 

must (1) demonstrate that the updated plan continues to meet all maintenance requirements 

and (2) document that growth and control strategy assumptions for all other source categories 

(area, non-road mobile, and stationary point) continue to be valid and any minor updates would 

not change the conclusions of the approved maintenance plan.

SECTION V-A: LEGAL AUTHORITY 

General 

The Texas Commission on Environmental Quality (TCEQ) has the legal authority to implement, 

maintain, and enforce the National Ambient Air Quality Standards (NAAQS) and to control the 

quality ofthe state's air, including maintaining adequate visibility. 

The first air pollution control act, known as the Clean Air Act of Texas, was passed by the Texas 

Legislature in 1965. In 1967, the Clean Air Act of Texas was superseded by a more 

comprehensive statute, the Texas Clean Air Act (TCAA), found in Article 4477-5, Vernon's Texas 

Civil Statutes. The legislature amended the TCAA in 1969, 1971, 1973, 1979, 1985, 1987, 1989, 

1991, 1993, 1995, 1997, 1999, 2001, 2003, 2005, 2007, 2009, and 2011. In 1989, the TCAA was 

codified as Chapter 382 of the Texas Health and Safety Code. 

Originally, the TCAA stated that the Texas Air Control Board (TACB) is the state air pollution 

control agency and is the principal authority in the state on matters relating to the quality of air 

resources. In 1991, the legislature abolished the TACB effective September 1, 1993, and its 

powers, duties, responsibilities, and functions were transferred to the Texas Natural Resource 

Conservation Commission (TNRCC). With the creation of the TNRCC, the authority over air 

quality is found in both the Texas Water Code and the TCAA. Specifically, the authority of the 

TNRCC is found in Chapters 5 and 7· Chapter 5, Subchapters A- F, H - J, and L, include the 

general provisions, organization, and general powers and duties of the TNRCC, and the 

responsibilities and authority of the executive director. Chapter 5 also authorizes the TNRCC to 

implement action when emergency conditions arise and to conduct hearings. Chapter 7 gives the 

TNRCC enforcement authority. In 2001, the 77th Texas Legislature continued the existence of 

the TNRCC until September 1, 2013, and changed the name of the TNRCC to the TCEQ. In 

2009, the 81st Texas Legislature, during a special session, amended section 5.014 of the Texas 

Water Code, changing the expiration date of the TCEQ to September 1, 2011, unless continued in 

existence by the Texas Sunset Act. In 2011, the 82nd Texas Legislature continued the existence 

of the TCEQ until 2023. 

The TCAA specifically authorizes the TCEQ to establish the level of quality to be maintained in 

the state's air and to control the quality of the state's air by preparing and developing a general, 

comprehensive plan. The TCAA, Subchapters A-D, also authorize the TCEQ to collect 

information to enable the commission to develop an inventory of emissions; to conduct research 

and investigations; to enter property and examine records; to prescribe monitoring 

requirements; to institute enforcement proceedings; to enter into contracts and execute 

instruments; to formulate rules; to issue orders taking into consideration factors bearing upon 

health, welfare, social and economic factors, and practicability and reasonableness; to conduct 

hearings; to establish air quality control regions; to encourage cooperation with citizens' groups 

and other agencies and political subdivisions of the state as well as with industries and the 

federal government; and to establish and operate a system of permits for construction or 

modification of facilities. 

Local government authority is found in Subchapter E of the TCAA. Local governments have the 

same power as the TCEQ to enter property and make inspections. They also may make 

recommendations to the commission concerning any action of the TCEQ that affects their 

territorial jurisdiction, may bring enforcement actions, and may execute cooperative agreements 

with the TCEQ or other local governments. In addition, a city or town may enact and enforce 

ordinances for the control and abatement of air pollution not inconsistent with the provisions of 

the TCAA and the rules or orders of the commission. 
Subchapters G and H of the TCAA authorize the TCEQ to establish vehicle inspection and 

maintenance programs in certain areas of the state, consistent with the requirements of the 

Federal Clean Air Act; coordinate with federal, state, and local transportation planning agencies 

to develop and implement transportation programs and measures necessary to attain and 

maintain the NAAQS; establish gasoline volatility and low emission diesel standards; and fund 

and authorize participating counties to implement vehicle repair assistance, retrofit, and 

accelerated vehicle retirement programs.

CHAPTER1: GENERAL(UPDATED) 

1.1 BACKGROUND AND INTRODUCTION (UPDATED) 

In 2008, the commission adopted the Eight-Hour Ozone Redesignation Request and 

Maintenance Plan for the Beaumont-Port Arthur (BPA) Ozone Nonattainment Area (Project No. 

2oo8-oo6-SIP-NR), which fulfills all Federal Clean Air Act (FCAA) requirements to redesignate 

the BPA ozone nonattainment area (Hardin, Jefferson, and Orange Counties) to attainment of 

the 1997 eight-hour ozone standard and demonstrates continued attainment of that standard 

through 2021. The plan was approved by the United States Environmental Protection Agency 

(EPA) effective November 19, 2010, at which time the BPA area was redesignated to attainment 

for the 1997 eight-hour ozone standard. The maintenance plan includes on-road mobile 

emissions inventories and nitrogen oxides (NOx) and volatile organic compounds (VOC) motor 

vehicle emissions budgets (MVEBs). 

MVEBs are established in the state implementation plan (SIP) and set the allowable on-road 

mobile NOx and VOC emissions that an area can produce while continuing to demonstrate 

attainment or maintenance. MVEBs are used in transportation conformity analyses, for which a 

nonattainment or maintenance area must show that its metropolitan transportation plans, 

transportation improvement programs, and projects funded by the Federal Highway 

Administration or the Federal Transit Administration do not exceed the MVEBs established in 

the SIP. Conformity must be demonstrated before area transportation plans can be approved or 

funded by the United States Department of Transportation or area metropolitan planning 

organizations (MPOs). 

The MVEBs established in the 2008 BP A maintenance plan were based on the mobile source 

emissions estimation model in use at that time, the EPA's MOBILE model. On March 2, 2010, 

the EPA officially released a new mobile source emissions estimation model, the Motor Vehicle 

Emission Simulator (MOVES) model, to replace the MOBILE model for SIP applications. 

Beginning March 2, 2013, transportation conformity must be conducted using the MOVES 

model. 

On September 9, 2011, the TCEQ received a letter from the South East Texas Regional Planning 

Commission, the BPA-area MPO, requesting the development of MOVES-based MVEBs to 

replace the existing MOBILE-based MVEBs. The letter indicated that the area was unable to 

conform to the existing MVEBs and would enter into a conformity lapse on September 25, 2012, 

which it has. The conformity lapse entails the cessation of new transportation projects and 

project phases until the area is able to conform to EPA-approved MVEBs. This SIP revision 

responds to the MPO's request by establishing new MVEBs to which the BPA transportation 

plan may be able to conform. 

1.1.1 Purpose of Plan (Updated) 

This SIP revision replaces the 2008 BPA maintenance plan on-road mobile source emissions 

inventories for NOx and VOC based on the EPA's MOBILE model with those based on the EPA's 

MOVES model, specifically MOVES2010a. On-road mobile source emissions inventory updates 

include those for 2005, 2011, 2014, 2017, and 2021. In addition, 2021 NOx and VOC MVEBs are 

updated according to the MOVES-based emissions inventories. 

1-1 
This SIP revision includes documentation to satisfy the EPA's MOVES implementation policy 

guidance 2 concerning updating maintenance plans with MOVES, which indicates that states 

must (1) demonstrate that the updated plan continues to meet all maintenance requirements 

and (2) document that growth and control strategy assumptions for all other source categories 

(area, non-road mobile, and stationary point) continue to be valid and any minor updates would 

not change the conclusions of the approved maintenance plan. 

1.1.2 One-Hour Ozone History in the BPAArea (No Change) 

1.1.3 Eight-Hour Ozone History in the BPAArea (Updated) 

1.1.3.1 2008 and 2010 Eight-Hour Ozone Standards (Added) 

On March 12, 2008, the EPA lowered the primary and secondary eight-hour ozone standards to 

0.075 parts per million (ppm). The governor recommended to the EPA in March 2009 that 

Hardin, Jefferson, and Orange Counties be designated as a nonattainment area for the 2008 

eight-hour ozone standard. In September 2009, the EPA announced that it intended to 

reconsider the 2008 ozone standard. On January 19, 2010, the EPA proposed revisions in the 

Federal Register (75 FR 2938) to strengthen the primary eight-hour ozone standard in the 

range of o.o6o to 0.070 ppm. On September 2, 2011, the President announced a request that the 

EPA withdraw the proposed, reconsidered ozone standard. 

In a September 2011 memo, the EPA announced that it would proceed with initial area 

designations under the 2008 (0.075 ppm) eight-hour ozone standard, starting with the 

recommendations states made in 2009 and updating those recommendations with the most 

current, certified air quality data (2008 through 2010). The governor submitted a revised 

designation recommendation in October 2011 that excluded Hardin, Jefferson, and Orange 

Counties from being designated as nonattainment under the reinstated 2008 eight-hour ozone 

standard. 

The EPA finalized designations for the 2008 eight-hour ozone standard effective July 20, 2012. 

At the same time, the EPA issued a final rulemaking to revoke transportation conformity under 

the 1997 eight-hour ozone standard one year after the effective date of designations under the 

2008 eight-hour ozone standard. Since the BPA area is designated attainment/unclassifiable for 

the 2008 eight-hour ozone standard and is a maintenance area for the 1997 eight-hour ozone 

standard, transportation conformity will no longer be required as of July 20, 2013. 

1.2 PUBLIC HEARING INFORMATION (UPDATED) 

The commission offered a public hearing in Beaumont on August 1, 2012, at 6:oop.m. in the 

Homer E. Nagel Conference Room of the South East Texas Regional Planning Commission at 

2210 Eastex Freeway, Beaumont, Texas 77703. Notice of public hearing for this SIP revision was 

published in the Texas Register and the Beaumont Enterprise newspaper. The public hearing 

was not opened because no one signed in to provide oral testimony. 

The public comment period opened on June 29, 2012, and closed on August 3, 2012. No written 

comments were received concerning this SIP revision.

2.1.1 Ozone Data (No Change) 

2.1.2 Ozone Trend Analysis (Updated) 

Ozone trends in the Beaumont-Port Arthur (BPA) area have been decreasing over the past 20 

years. Figure 2-1: Ozone Design Value Trends in the BPAArea shows decreases in both the 

eight-hour and one-hour ozone design values. Although both the eight-hour and the one-hour 

design values increased from 2010 to 2011, the overall design value trend has been decreasing. 

The eight-hour ozone design value has decreased by 22% over the past 20 years and the onehour ozone design value had decreased by 27% over the past 20 years. The 2011 eight-hour 

ozone design value for the BPA area was 79 parts per billion (ppb ), which is below the 1997 

eight-hour ozone standard of 84 ppb (o.o8 parts per million (ppm)). The BPA area has not 

exceeded the eight-hour ozone standard since 2006. The 2011 one-hour ozone design value for 

the BPA area was 110 ppb, which is also below the revoked one-hour ozone standard of 125 ppb 

(0.12 ppm). The decreases in ozone have occurred despite increases in population in the BPA 

area, as shown in Figure 2-2: Ozone Design Values and Population Trends in the BPAArea. 

Figure 2-3: Ozone Exceedance Days and Number of Monitors in the BPAArea shows that the 

number of eight-hour ozone exceedance days has decreased in the BPA area despite an increase 

in the number of monitors. Although there were more eight-hour ozone exceedance days in 2011 

compared to 2010, the overall trend in exceedance days is decreasing. There were only four 

eight-hour ozone exceedance days in the BPA area in 2011, an unusual year with recordbreaking temperatures and an unusual number of days that favored the development of ozone. 

Because the exceedance day count is dependent on the number of monitors in the area, the 

number of eight-hour ozone exceedance days by monitor is shown in Figure 2-4: Eight-Hour 

Ozone Exceedance Days by Monitor in the BPA Area. Exceedances by monitor tend to vary 

from year to year; however, the overall trend in the number of eight-hour ozone exceedance days 

has been decreasing over the past 20 years.

2.3.3.1 Nitrogen Oxides Trends (Updated) 

Overall, nitrogen oxides (NOx) trends in the BPA area are decreasing. Figure 2-5: Average NOx 

Trends in the BPA Area shows the NOx trends at five monitors in the BPA area: Beaumont 

Downtown (CAMS 2/CAMS 112/ CAMS 2002), Jefferson County Airport (CAMS 

1019/CAMS2001), Hamshire (CAMS 64/CAMS 654), Nederland High School (CAMS 1035), and 

West Orange (CAMS 9/CAMS141). Data for 2011 cover only the first two quarters of the year, 

and NOx averages during 2011 are subject to change. The average NOx concentration has 

remained relatively flat at most monitors until sometime from 2003 to 2006. After 2006, the 

last year the BP A area had an ozone design value exceed 84 ppb, most monitors showed a large 

decrease in NOx concentrations. West Orange (CAMS 9/CAMS141) did show a slight increase in 

average NOx concentrations from 2010 to 2011, but the overall trend from 1991 to 2011 shows a 

decrease of 54%. NOx decreased 26% from 1991 to 2011 at the Beaumont Downtown (CAMS 

2/CAMS 112/ CAMS 2002) site, 40% from 2000 to 2011 at the Hamshire (CAMS 64/CAMS 654) 

site, and so% from 2006 to 2011 at the Nederland High School (CAMS 1035) site.

VOC canister data have also been available in the BPA area since 1994. The VOC canister 

samples are 24-hour averages and are sampled every 6 days. Figures 2-8: Median Ethylene 

Trends from Canister Data in the BPAArea and 2-9: Median Propylene Trends from Canister 

Data in the BPA Area both show that ethylene and propylene, two of the most reactive VOC, 

have been decreasing at nine canister sites in the BPA area over the past 14 and 17 years, 

respectively. Only one quarter of data are available for 2011, so concentrations are subject to 

change. While the ethylene concentrations are generally higher than the propylene 

concentrations, the median ethylene concentrations have decreased at the nine canister sites 

(one of the eight sites has three monitors), with an average decrease of 41%. West Orange 

(CAMS 9/CAMS141) and Beaumont Mary (CAMS 1050) both showed increases in ethylene; 

however, the West Orange (CAMS 9/CAMS141) canister site stopped operation in 2006, and the 

Beaumont Mary (CAMS 1050) site has only been in operation for two years. Similarly, median 

propylene concentrations have decreased at the nine canister sites, with an average decrease of 

42%. Again, the Beaumont Mary (CAMS 1050) site showed a slight increase in propylene 

concentrations, but it has only been in operation for two years. For both propylene and ethylene, 

the increase at Beaumont Mary (CAMS 1050) was less than 0.5 ppb.

CHAPTER 3: ATTAINMENT EMISSIONS INVENTORY (NO CHANGE) 

3-1 
CHAPTER4: MAINTENANCE DEMONSTRATION (UPDATED) 

4.1 GENERAL (UPDATED) 

This state implementation plan (SIP) revision is an update to the 2008 Beaumont-Port Arthur 

(BPA) maintenance plan that revises the original on-road mobile source emissions inventories 

and nitrogen oxides (NOx) and volatile organic compounds (VOC) motor vehicle emissions 

budgets (MVEBs) to be based on the United States Environmental Protection Agency's (EPA) 

Motor Vehicle Emission Simulator (MOVES) model. The on-road mobile source emissions 

inventories and MVEBs adopted with the 2008 BP A maintenance plan, which was approved by 

the EPA effective November 19, 2010, were developed using the MOBILE emissions estimation 

model. On March 2, 2010, the EPA officially released the MOVES model to replace the MOBILE 

model for SIP applications. Beginning March 2, 2013, transportation conformity must be 

conducted using the MOVES model. This update to the 2008 BPA maintenance plan would 

facilitate future, required, MOVES-based transportation conformity determinations. 

The EPA provided a guidance documene to assist states in incorporating MOVES-based onroad mobile source emissions inventories and MVEBs into existing area maintenance plans. The 

guidance allows states, under stipulated conditions, to update only the on-road mobile source 

portions of their maintenance plans. States must (1) demonstrate that the updated plan 

continues to meet all maintenance requirements and (2) document that growth and control 

strategy assumptions for all other source categories (area, non-road mobile, and stationary 

point) continue to be valid and any minor updates would not change the conclusions of the 

approved maintenance plan. 

This SIP revision satisfies both conditions of the MOVES guidance document; therefore, only 

Section 4-4.2: On-Road Mobile Sources has been revised. For each of the other source categories 

(area, non-road mobile, and stationary point), sections have been added describing that any 

minor updates have not changed the conclusions of the 2008 BPA maintenance plan: Section 

4.2.1.2: Updated Verification ofContinuedAttainmentfor Area Sources; Section 4.2.3.3: 

Updated Verification ofContinuedAttainmentfor Non-Road Mobile Sources; and Section 

4.2-4-4: Updated Verification ofContinuedAttainmentfor Stationary Point Sources. 

4.2 FU1URE EMISSIONS AND VERIFICATION OF CONTINUED ATTAINMENT 

(UPDATED) 

MOVES-based on-road mobile source NOx and VOC emissions estimates change slightly from 

the MOBILE-based estimates adopted with the 2008 BPA maintenance plan. Table 4-1: 

MOBILE-Based On-Road Mobile Source NOx and VOC Emissions in the BPA Area (2005, 2011, 

2014, 2017, and 2021) summarizes, in tons per day (tpd), the on-road mobile source emissions 

estimates (MOBILE-based) that were included in the original maintenance plan. Emissions 

estimates for area, non-road mobile, and stationary point sources were not included in Table 4-1 

because they were not updated from the 2008 BPA maintenance plan. MOVES-based NOx and 

VOC on-road mobile source emission estimates are summarized in Tables 4-2: Updated 

Summary ofNOx Emissions in BPA by Source Type (2005, 2011,2014,2017, and 2021) and 4-

The 2008 BP A maintenance plan demonstrates that overall NOx emissions are projected to 

decline by 15.36 tpd from 2005 through 2021 using MOBILE-based on-road emissions 

estimates. Updating the BPA maintenance plan to incorporate the MOVES model still results in 

a decline in projected NOx emissions; however, the decline is slightly smaller, 10.80 tpd. The 

original maintenance plan (MOBILE-based) demonstrated an increase in overall VOC emissions 

projections from 2005 through 2021, 12.72 tpd. While MOVES-based projections also show an 

increase in overall VOC emissions, that increase is smaller, 12.18 tpd. 

Although there is a slight estimated increase in VOC over the 16 years projected for the BPA 

maintenance plan, it has been established that NOx emissions reductions are more effective 

than VOC reductions at reducing ozone design values in the BPA area. In fact, photochemical 

modeling analysis adopted with the 2008 BP A maintenance plan showed that reductions in NOx 

emissions are 3.76 times as effective as VOC reductions at reducing the BPA-area ozone design 

value. In its proposed approval of the 2008 plan in the Federal Register (75 FR 27514), the EPA 

supported the 2008 demonstration by stating that "based on photochemical modeling analyses 

showing that the formation of ozone in the BP A area is more sensitive to NOx than to VOC 

emissions, the increase in VOC emissions is expected to be fully offset by the decrease in NOx." 

4-3 
Based on the photochemical modeling analysis included in the original 2008 BP A maintenance 

plan and supported by the EPA, emissions in the BP A area are expected to remain at levels 

consistent with attainment for the 1997 eight-hour ozone standard through 2021. Please see 

Section 4.2: Future Emissions and Verification of Continued Attainment ofthe original2oo8 

BP A maintenance plan for further details on the photochemical modeling analysis 

demonstrating the effectiveness of NOx in reducing ozone design values in the BP A area. 

4.2.1 Area Sources (Updated) 

4.2.1.1 Flash Emissions from Upstream Oil and Gas Production (No Change) 

4.2.1.2 Updated Verification of Continued Attainment for Area Sources (Added) 

In reviewing the 2008 BP A maintenance plan and applying updates, the TCEQ determined that 

emissions would be further decreased for both NOx and VOC. There are two factors attributed to 

these reductions: updated growth factors provided by the Eastern Research Group through a 

contract in 2010; 4 and speciation updates performed on the oil and gas categories for 2005. 

Although minor updates have occurred in the area source category since the 2008 submission, 

those updates do not change the overall conclusions of the BP A maintenance plan SIP revision. 

4.2.2 On-Road Mobile Sources (Updated) 

The Texas Commission on Environmental Quality (TCEQ) updated the 2008 BP A maintenance 

plan's on-road mobile source emissions inventory estimates for this SIP revision by contracting 

with the Texas Transportation Institute (TTI). TTl developed detailed, hourly, link-based ozone 

season weekday emissions estimates for the three BP A counties, Jefferson, Hardin, and Orange, 

using the newest version of the EPA's MOVES model, MOVES2010a. The updated emissions 

inventory estimates include NOx and VOC emissions for the 2005 base year, the 2011, 2014, and 

2017 interim years, and the 2021 horizon year. TTl also used the latest planning assumptions to 

develop the maintenance inventories in an effort to ensure that the MVEBs would be consistent 

with transportation conformity analysis assumptions. 

TTl produced emissions estimates using a link-based methodology that used a travel demand 

model (TDM) and MOVES "rates-per-activity." Emissions were estimated by hourly and 24-

hour periods by MOVES source use type and fuel type, pollutant process, and TDM roadway 

class. The most recently available data were used, including Texas Department of 

Transportation (TxDOT) vehicle classification counts and TxDOT /Texas Department of Motor 

Vehicles registration data. MOVES default data were used as needed. Control programs that 

were modeled in the analysis include: 

• Federal Motor Vehicle Control Program Standards; 

• Federal Low Emissions Heavy-Duty Diesel Engines Rebuild Program; 

• Federal Heavy-Duty 2004 Pull-Ahead Program; 

• Conventional Gasoline with Federal Low Reid Vapor Pressure; and 

• Diesel Fuel with Texas Low Emission Diesel as appropriate for applicable years. 

For the fuel programs, MOVES defaults, fuel survey data, and federally regulated values were 

used. Details of how these were modeled are found in Appendix D: BPAArea On-Road 

Emissions Inventories for SIP Submission- 2005,2011,2014,2017, and 2021, TTl Report,

4.2.2.1 Motor Vehicle Emissions Budgets (Updated) 

The 2008 BPA maintenance plan established MOBILE-based MVEBs, setting the allowable onroad mobile emissions that an area can produce while continuing to demonstrate maintenance. 

Local transportation planning organizations demonstrate that projected emissions from 

transportation plans, programs, and projects are equal to or less than the MVEBs as required by 

the federal transportation conformity rule. The NOx and VOC on-road mobile source emissions 

inventory totals for 2021, the final year of this maintenance plan, establish the MVEBs. The 

MOVES-based MVEBs for this SIP revision are summarized in Table 4-7: 2021 Horizon Year 

MVEBsfor the BPA area using MOVES2010a. Detailed documentation ofMVEB calculations, 

modeling methods, and input parameter development and usage is provided in Appendix D.

4.2.3.2 Locomotives and Marine Vessels (No Change) 

4.2.3.3 Updated Verification of Continued Attainment for Non-Road Mobile Sources (Added) 

NONROAD Model 

For all Texas non-road mobile source categories except aircraft, airport equipment, locomotives, 

and commercial marine vessels, emissions are calculated using the Texas-Specific NONROAD 

(TexN) model that utilizes the EPA's latest NONROAD model. While the TexN model utilizes 

input files and post-processing routines to estimate Texas-specific emissions estimates, it 

4-5 
retains the EPA's NONROAD model as the core model to conduct the basic emissions 

calculations. 

The EPA's NONROAD2005 model, which was used as the core model for the 2008 BPA 

maintenance plan, was updated to the NONROAD2oo8a version in April 2009. The 

NONROAD2oo8a model accounted for the addition of two new federal rules that affect the 

equipment categories in the non-road mobile source sector; therefore, the TexN model was 

updated accordingly. In addition, equipment survey studies have been conducted and emissions 

updated for the diesel construction equipment sector, the agricultural equipment sector, and 

drilling rig diesel engines since 2009. 

Using current methodology and the TexN/EPA NONROAD2oo8a model, emissions calculated 

for each county in the BP A area are, overall, lower and demonstrate a downward trend for both 

NOx and VOC compared to the emissions reported in the 2008 BPA maintenance plan. 

Although minor updates have occurred in the non-road mobile source category since the 2008 

submission, those updates do not change the overall conclusions of the BP A maintenance plan. 

Airports 

The Federal Aviation Administration's Emissions and Dispersion Modeling System (EDMS) 

version 5.1 was used to estimate NOx and VOC emissions for commercial aircraft, general 

aviation, and ground support equipment emissions in the 2008 BP A maintenance plan. The 

model has not changed since the 2008 submission, and the repopulated EDMS files, which 

reflect 2011 operations, indicate that both NOx and VOC emissions declined between 2005 and 

2011. 

The 2011 emissions calculated for the airports source category in the BPA area demonstrate a 

downward trend for both NOx and VOC compared to the emissions reported in the 2008 BPA 

maintenance plan. Although minor updates have occurred in the airports source category since 

the 2008 submission, those updates do not change the overall conclusions of the BPA 

maintenance plan. 

Locomotives and Commercial Marine Vessels 

Texas Air Emissions Repository (TexAER) data from 2005, which were developed from the 

2005 Consolidated Emissions Reporting Rule data, were used to estimate NOx and VOC 

emissions from locomotive and commercial marine vessel activities in the 2008 BP A 

maintenance plan. The methodology has not changed since the 2008 submission. 

Actual 2011 emissions calculated for locomotive and commercial marine vessel activities in the 

BP A area, when compared to the projected 2011 emissions reported in the 2008 BP A 

maintenance plan, are lower and demonstrate a downward trend for both NOx and VOC. Since 

the original inventories conservatively estimated future year locomotive and commercial marine 

vessel activities emissions, recalculation of the milestone year inventories would not change the 

overall conclusions of the 2008 BP A maintenance plan.

4.2.4.3 Updated Uncontrolled Milestone Year Inventories (No Change) 

4.2.4.4 Updated Verification of Continued Attainment for Stationary Point Sources (Added) 

There have been no changes to the point source emissions inventories included in the 2008 BP A 

maintenance plan. Those inventories projected positive point source emissions growth for all 

future milestone years. Actual point source emissions for 2008 through 2010 are below the 

2005 base year emissions, below emissions trends projected in the maintenance plan, and are 

anticipated to remain below projected emissions. Since the original inventories conservatively 

estimated future year point source emissions, recalculation of the milestone year inventories 

would not change the overall conclusions of the 2008 BP A maintenance plan. 

4·3 CONTROL STRATEGIES (NO CHANGE) 

4·4 EMISSIONS SUMMARY (UPDATED) 

Updated percentages of emissions by source category for 2005, 2011, 2014, 2017, and 2021 are 

reflected in Tables 4-8: Updated Percentages ofNOx Emissions in BPA by Source Category and 

4-9: Updated Percentages ofVOCEmissions in BPA by Source Category. The percentages of 

contribution from source categories have changed slightly with the MOVES-based on-road 

mobile source emissions inventory updates. Table 4-8 shows that on-road mobile source 

emissions determined using the MOVES model account for a slightly larger percentage ofNOx 

emissions, overall, than those determined using the MOBILE model. Table 4-9 shows that onroad mobile source emissions determined using the MOVES model account for a slightly smaller 

percentage ofVOC emissions, overall, than those determined using the MOBILE model. As in 

the 2008 BPA maintenance plan, these tables show that the largest man-made contribution of 

NOx is from stationary point sources and the largest man-made contribution ofVOC is from 

area sources. Contributions from biogenic emissions are not included in the summary because 

the maintenance measures are limited to the reduction of man-made emissions.

4·5 CONTINUED MAINTENANCE WITH MOVES-BASED ON-ROAD MOBILE 

EMISSIONS INVENTORIES (ADDED) 

Revising the on-road mobile source emissions inventories and MVEBs for this SIP revision only 

minimally affects projected NOx and VOC emissions trends from the 2005 base year across the 

2011, 2014, and 2017 milestone years and the 2021 horizon year; however, NOx emissions are 

still projected to decrease and VOC emissions are still projected to increase (see Tables 4-2 and 

4-3). On-road mobile source emissions inventories were the only inventories updated; however, 

in determining whether to update inventories for the other source categories, the TCEQ found 

that area, non-road mobile, and stationary point source emissions all trend below the 

projections included in the 2008 BP A maintenance plan. In addition, photochemical modeling 

analyses adopted with the 2008 BP A maintenance plan and supported by the EPA demonstrate 

that the formation of ozone in the BP A area is more sensitive to NOx than to VOC emissions. 

The slight increase in VOC emissions, which was shown in the original BP A maintenance plan as 

well, is offset by the decrease in NOx emissions. Those factors, along with the overall downward 

trend in ozone design values for the BPA area, show that this SIP revision continues to meet all 

requirements for maintenance of the 1997 eight-hour ozone standard.

REVISIONS TO THE STATE IMPLEME:t\"'TATION PL.L\.N 

Docket No. 2012-oSos-SIP 

Project No. 2012-oos-SIP-NR 

On November 14, 2012, the Texas Commission on Environmental Quality 

(Commission), during a public meeting, considered adoption of a re·vision to the BeaumontPortArthur (EPA) Maintenance Plan for the 1997 Eight-Hour Ozone Standard. The 

Commission adopts this revision to the state implementation plan (SIP). The adopted SIP 

revision replaces the 2008 EPA maintenance plan on-road mobile source emissions 

inventories for nitrogen oxides (NOx) and volatile organic compounds (VOC) based on the 

United Stated Environmental Protection Agency's MOBILE model -vvith those based on the 

EPA's Motor Vehicle Emission Simulator (MOVES) model. On-road mobile source emissions 

inventory updates include those for 2005, 2011, 2014, 2017, and 2021. The 2021 NOx and 

VOC motor vehicle emission budgets (MVEBs) are also updated based on the MOVES-based 

emissions inventories. Under Tex. Health & Safety Code Ann. §§382.011, 382.012, and 

382.023 (Vernon 2011), the Commission has the authorit~y to control the quality of the state's 

air and to issue orders consistent -vvith the policies and purposes of the Texas Clean Air Act, 

Chapter 382 of the Tex. Health & Safety Code. Notice of the proposed SIP revision was 

published for comment in the July 13, 2012 issue of the Texas Register (37 TexReg 5368). 

Pursuant to 40 Code of Federal Regulations §51.102 and after proper notice, the 

Commission offered a public hearing to consider the revision to the SIP. Proper notice 

included prominent advertisement in the area affected at least 30 days prior to the date of the 

hearing. A public hearing was offered in Beaumont on August 1, 2012. 

The Commission circulated hearing notic.es of its intended action to the public, 

including interested persons, the Regional Administrator of the EPA, and all applicable local 

air pollution control agencies. The public was imited to submit data, views, and 

recommendations on the proposed SIP revisions, either orally or in ·writing, at the hearing or 

during the comment period. Prior to the scheduled hearing, copies of the SIP re·vision were 

available for public inspection at the Commission's central office and on the Commission's 

Web site. 

No comments ·were received regarding the SIP Ie"\ision. 

IT IS THEREFORE ORDERED BY THE COMMISSION that the revision to the SIP 

incorporated by reference to this Order is hereby adopted. The adopted revision to the SIP is 

incorporated by reference in this Order as if set forth at length verbatim in this Order. 

IT IS FURTHER ORDERED BY THE COMMISSION that on behalf of the Commission, 

the Chairman should transmit a copy of this Order, together v\ith the adopted revision to the 
SIP, to the Regional Administrator of EPA as a proposed revision to the Texas SIP pursuant to 

the Federal Clean Air Act, codified at 42 U.S. Code Ann. §§7401- 7671q, as amended. 

If any portion of this Order is for any reason held to be invalid by a court of competent 

jurisdiction, the invalidity of any portion shall not affect the validity of the remaining 

portions.
