Proposal June 27, 2012

### Thispage intentionally left blankEXECUTIVE SUMMARY In 2008, the commission adopted the Eight-Hour Ozone Redesignation Request and Maintenance Plan for the Beaumont-PortArthur (BPA) Ozone NonattainmentArea (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 ofthat standard through 2021. The plan was approvedbythe United States Environmental ProtectionAgency (EPA) effective November 19, 2010, andthe BPA area was redesignated to attainment for the 1997 eight-hour ozone standard. The 2008 BPA maintenance plan contains on-roadmobile emissions inventories, a nitrogen oxides (NOx) motor vehicle emissionsbudget (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 mustbe conductedusing the MOVES model. To demonstrate transportation conformity, a nonattainment or maintenance area must show that its metropolitan transportationplans, transportation improvementprograms, and projects funded bythe Federal HighwayAdministration orthe FederalTransitAdministration conform to the MVEBs established in the state implementationplan (SIP). Conformity mustbe demonstratedbefore area transportationplans canbe approved orfunded bythe United States Department ofTransportation orthe 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 byproviding MVEBs based onthelatest version ofthe MOVES model, MOVES2010a. This proposed SIP revision would replace the 2008 BPA maintenance plan on-road mobile source emissions inventories for NOx andVOC based onthe EPA's MOBILE model with those based onthe EPA's MOVES model. On-roadmobile source emissions inventoryupdates include those for 2005, 2011, 2014, 2017, and 2021. In addition, 2021 NOx andVOC MVEBs wouldbe updatedbased onthe MOVES-based emissions inventories. This proposed SIP revision includes documentation to satisfythe EPA's MOVES implementationpolicy guidance 1 concerning updating maintenance plans with MOVES, which indicates that states must (1) demonstrate thattheupdated 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 stationarypoint) continue to bevalid and any minor updates would not change the conclusions ofthe approved maintenance plan.

Transportation and Regional Programs Division, Office ofTransportation andAir Quality, U.S. Environmental ProtectionAgency, EPA-420-B-09-046, December 2009. ES-1SECTIONV-A: LEGALAUTHORITY General The Texas Commission on Environmental Quality (TCEQ) has the legal authorityto implement, maintain, and enforce theN ationalAmbientAir Quality Standards (NAAQS) andto control the quality ofthe state's air, including maintaining adequate visibility. The first air pollution control act, known as the CleanAirAct ofTexas, was passedbytheTexas Legislature in 1965. In 1967, the CleanAir Act ofTexas was supersededby a more comprehensive statute, the Texas Clean AirAct (TCAA), found in Article 4477-5, Vernon's Texas Civil Statutes. The legislature amendedtheTCAA in 1969, 1971, 1973, 1979, 1985, 1987, 1989, 1991, 1993, 1995, 1997, 1999, 2001, 2003, 2005, 2007, 2009, and 2011. In 1989, theTCAA was codified as Chapter 382 ofthe Texas Health and SafetyCode. Originally, theTCAA statedthattheTexas Air Control Board (TACB) is the state airpollution control agency and is theprincipal authority in: the state on matters relating to the quality ofair resources. In 1991, the legislature abolished theTACB effective September 1, 1993, and its powers, duties, responsibilities, andfunctions were transferred to the Texas Natural Resource Conservation Commission (TNRCC). With the creation oftheTNRCC, the authority over air qualityis found inboththeTexas Water Code and theTCAA. Specifically, the authorityofthe TNRCC is found in Chapters 5 and 7· Chapter 5, SubchaptersA- F, H- J, and L, include the general provisions, organization, and general powers and duties ofthe TNRCC, and the responsibilities and authority ofthe executive director. Chapter 5 also authorizes the TNRCC to implement action when emergency conditions arise andto conducthearings. Chapter 7 gives the TNRCC enforcement authority. In 2001, the 77th Texas Legislature continuedthe existence of theTNRCC until September 1, 2013, and changedthe name ofthe TNRCC to theTCEQ. In 2009, the 81stTexas Legislature, during a special session, amended section 5.014 oftheTexas Water Code, changing the expiration date ofthe TCEQ to September 1, 2011, unless continued in existence bythe Texas SunsetAct. In 2011, the 82ndTexas Legislature continuedthe existence ofthe TCEQ until 2023. The TCAA specifically authorizes the TCEQ to establish the level ofquality tobe maintained in the state's air andto control the quality ofthe state's airbypreparing 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 inventoryofemissions; to conduct research andinvestigations; to enterproperty and examine records; toprescribe monitoring requirements; to institute enforcement proceedings; to enterinto contracts and execute instruments; to formulate rules; to issue orders taking into consideration factors bearing upon health, welfare, social and economic factors, andpracticability and reasonableness; to conduct hearings; to establish air quality control regions; to encourage cooperation with citizens' groups and other agencies andpolitical subdivisions ofthe state as well as with industries and the federal government; and to establish and operate a system ofpermits for construction or modification offacilities. Local government authority is found in Subchapter E ofthe TCAA. Local governments have the same power as the TCEQ to enterproperty and make inspections. They also may make recommendations to the commission concerning any action ofthe TCEQ that affects their territorialjurisdiction, maybring enforcement actions, and may execute cooperative agreements with theTCEQ or otherlocal governments. In addition, a city or town may enact and enforce ordinances for the control and abatement ofairpollution not inconsistentwith the provisions of theTCAA andthe rules or orders ofthe commission.Subchapters G and H ofthe TCAA authorize theTCEQ to establish vehicle inspection and maintenanceprograms in certain areas ofthe state, consistent with the requirements ofthe Federal Clean AirAct; coordinate with federal, state, andlocal transportationplanning agencies to develop and implement transportationprograms and measures necessaryto attain and maintain the NAAQS; establish gasoline volatility andlow emission diesel standards; andfund and authorize participating counties to implement vehicle repair assistance, retrofit, and acceleratedvehicle retirement programs.

XCHAPTER1: 

### GENERAL(UPDATED) 1.1 BACKGROUND AND INTRODUCTION 

### (UPDATED) 1.1.1 Purpose ofPlan (Updated) In 2008, the commission adopted the Eight-Hour Ozone Redesignation Request and Maintenance Plan for the Beaumont-PortArthur (BPA) Ozone NonattainmentArea (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 ofthat standard through 2021. The plan was approvedbythe United States Environmental ProtectionAgency (EPA), effective November 19, 2010, andthe 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 emissionsbudget (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 MotorVehicle Emission Simulator (MOVES) model, to replace the MOBILE model for SIP applications. Beginning March 2, 2013, transportation conformity mustbe conducted using the MOVES model. To demonstrate transportation conformity, a nonattainment or maintenance area must showthat its metropolitan transportation plans, transportation improvement programs, and projects funded bythe Federal HighwayAdministration or the Federal TransitAdministration conform to the MVEBs established in the state implementationplan (SIP). Conformitymustbe demonstratedbefore area transportation plans can be approved orfunded bythe United States Depa,rtment ofTransportation orthe 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 byproviding MVEBs based on the latest version ofthe MOVES model, MOVES2o10a. This proposed SIP revision would replace the 2008 BPA maintenance plan on-road mobile source emissions inventories for NOx andVOC based on the EPA's MOBILE model with those based on the EPA's MOVES model. On-road mobile source emissions inventoryupdates include those for 2005, 2011, 2014, 2017, and 2021. In addition, 2021 NOx andVOC MVEBs would be updated according to the MOVES-based emissions inventories. This proposed SIP revision includes documentation to satisfythe EPA's MOVES implementationpolicy guidance2 concerning updating maintenance plans with MOVES, which indicates that states must (1) demonstrate that the updatedplan 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 stationarypoint) continue to bevalid and any minor updates would not change the conclusions ofthe approved maintenance plan.

### (No Change) 1.1.3 Eight-Hour Ozone Historyinthe BPAArea 

### (Updated) 1.1.3.1 2008 and 2010 Eight-Hour Ozone Standards 

### (Added) On March 12, 2008, the EPAlowered theprimary and secondary eight-hour ozone standards to 0.075 parts permillion (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 itintendedto reconsider the 2008 ozone standard. On January 19, 2010, the EPAproposed revisions inthe 

### Federal Register (75 FR 2938) to strengthenthe primaryeight-hour ozone standard in the range ofo.o6o to 0.070 ppm. On September 2, 2011, the President announced a request thatthe EPA withdrawtheproposed, reconsidered ozone standard. In a September 2011 memo, the EPA announcedthat itwould proceed with initial area designations underthe 2008 (0.075 ppm) eight-hour ozone standard, startingwith the recommendations states madein 2009 andupdating 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 nonattainmentunder 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 conformityunderthe 1997 eight-hour ozone standard on May 21, 2012. Since the BPA area is designated attainmentjunclassifiable for the 2008 eight-hour ozone standard andis a maintenance area for the 1997 eight-hour ozone standard, transportation conformity will no longerbe required upon the effective date ofrevocation oftransportation conformityfor the 1997 eight-hour ozone standard, July 20, 2013.
1.2 PUBLIC HEARING INFORMATION (UPDATED) The commission will offer a public hearing in Beaumont onAugust 1, 2012, at six o'clock inthe evening. The public hearingwill beheldinthe Homer E. Nagel Conference Room ofthe South East Texas Regional Planning Commission at 2210 Eastex Freeway, Beaumont, Texas 77703. The public comment periodwill open onJune 29, 2012, and will close onAugust 3, 2012. Notice ofpublichearing for this SIP revision will be publishedin the

### Ozone Data (No Change) 2.1.2 

### OzoneTrendAnalysis (Updated) Ozone trends in the Beaumont-PortArthur (BPA) areahave been decreasing over thepast 20 years. Figure 2-1: 

### Ozone Design Value Trends in the BPAArea shows decreases inboth the eight-hour and one-hour ozone design values. Although both the eight-hour andthe one-hour design values increased from 2010 to 2011, the overall design value trendhas been decreasing. The eight-hour ozone design value has decreasedby 22% over thepast 20 years andthe onehour ozone design value had decreasedby 27% over the past 20 years. The 2011 eight-hour ozone design value for the BPA areawas 79 parts perbillion (ppb), which is belowthe 1997 eight-hour ozone standard of84ppb (o.o8 parts per million (ppm)). The BPA areahas not exceeded the eight-hour ozone standard since 2006. The 2011 one-hour ozone design value for the BPA area was 110ppb, which is also below the revoked one-hour ozone standard of 125ppb (0.12 ppm). The decreases in ozone have occurred despite increases inpopulation in the BPA area, as shown in Figure 2-2: 

### Ozone Design Values andPopulation Trends in theBPAArea. Figure 2-3: 

### Ozone Exceedance Days andNumber of Monitors in theBPAArea shows thatthe number ofeight-hour ozone exceedance days has decreased in the BPA area despite an increase in the number ofmonitors. Although there were more eight-hour ozone exceedance days in 2011 comparedto 2010, the overall trend in exceedance days is decreasing. There were onlyfour eight-hour ozone exceedance days in the BPA area in 2011, an unusual year with recordbreaking temperatures and an unusual number ofdays thatfavored the development ofozone. Because the exceedance day count is dependent on the number ofmonitors in the area, the number ofeight-hour ozone exceedance days by monitoris shown in Figure 2-4: 

### Eight-Hour Ozone Exceedance Days byMonitor in the BPAArea. Exceedances bymonitortendto vary from year to year; however, the overall trend in the number ofeight-hour ozone exceedance days has been decreasing overthe past 20 years.

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

### AverageNOx Trends in the BPAArea shows the NOx trends at five monitors in the BPA area: Beaumont Downtown (CAMS 2/CAMS 112/ CAMS 2002), Jefferson CountyAirport (CAMS 1019/CAMS2001), Hamshire (CAMS 64/CAMS 654), Nederland High School (CAMS 1035), and West Orange (CAMS 9/CAMS141). Data for 2011 cover onlythe first two quarters ofthe year, and NOx averages during 2011 are subject to change. The average NOx concentrationhas remained relatively flat at most monitors until sometimefrom 2003 to 2006. After 2006, the lastyear the BPA areahad an ozone design value exceed 84 ppb, most monitors showed a large decrease inNOx concentrations. West Orange (CAMS 9/CAMS141) did show a slight increase in average NOx concentrations from 2010 to 2011, but the overall trendfrom 1991 to 2011 shows a decrease of54%. NOx decreased 26% from 1991 to 2011 atthe Beaumont Downtown (CAMS 2/CAMS 112/ CAMS 2002) site, 40% from 2000 to 2011 atthe Hamshire (CAMS 64/CAMS 654) site, and so% from 2006 to 2011 at the Nederland High School (CAMS 1035) site.

### Volatile Organic CompoundsTrends (Updated) Continuous volatile organic compounds (VOC) data are collected at two automated gas chromatograph (AutoGC) monitors in the BPA 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, andAugust 29, 2006, respectively, and ending on December 1, 2011. Note that thelast month ofdatafrom 2011 is not yet available

. Figures 2-6: Median Ethylene atAutoGCs in theBPAArea and 2-7: Median Propylene atAutoGCs in the BPAArea show the median ethylene andpropylene concentrations at the two AutoGC monitors in the BPA area, respectively. Both ethylene andpropylene 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 1035).

### Median Propylene Trends from Canister Data in the BPAAreaboth show that ethylene and propylene, two ofthe most reactive VOC, have been decreasing at nine canister sites inthe BPA area over the past 14 and 17 years, respectively. Only one quarter ofdata are available for 2011, so concentrations are subject to change. While the ethylene concentrations are generallyhigher than thepropylene concentrations, the median ethylene concentrations have decreased at the nine canister sites (one ofthe eight sites has three monitors), with an average decrease of41%. West Orange (CAMS 9/CAMS141) and Beaumont Mary (CAMS 1050) both showed increases in ethylene; however, theWest Orange (CAMS 9/CAMS141) canister site stopped operation in 2006, and the Beaumont Mary (CAMS 1050) site has onlybeen 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 ithas onlybeen in operation for two years. For both propylene and ethylene, the increase at Beaumont Mary (CAMS 1050) was less than 0.5 ppb.

### This proposed state implementation plan (SIP) revision is an update tothe 2008 

### BeaumontPortArthur (BPA) maintenance planthat revises the original on-road mobile source emissions inventories, nitrogen oxides (NOx) motorvehicle emissions budget (MVEB), andvolatile organic compounds (VOC) MVEB to be based on the United States Environmental ProtectionAgency's (EPA) MotorVehicle Emission Simulator (MOVES) model. The on-road mobile source emissions inventories and MVEBs adopted with the 2008 

### BPA maintenance plan, which was approved bythe 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 mustbe 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 andMVEBs into existing area maintenance plans. The guidance allows states, under stipulated conditions, to update only the on-road mobile source portions oftheir 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 bevalid and any minorupdates would not change the conclusions ofthe approved maintenance plan. This proposed SIP revision satisfies both conditions ofthe MOVES guidance document; therefore, only Section 4-4.2: 

### On-RoadMobile Sources has been revised. For each ofthe other source categories (area, non-road mobile, and stationarypoint), sections have been added describing that any minor updates have not changed the conclusions ofthe 2008 

### BPA maintenance plan: Section 4.2.1.2: 

### Updated Verification ofContinuedAttainmentforArea Sources; Section 4.2.3.3:

Updating the BPA maintenance plan to incorporate the MOVES model would still result in a decline inprojected NOx emissions; however, the decline wouldbe slightly smaller, 10.80 tpd. The original maintenanceplan (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 inVOC over the 16 years projected for the BPA maintenance plan, it hasbeen 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 ofthe 2008 plan in the

### Federal Register (75 FR 27514), the EPA supportedthe 2008 demonstrationbystatingthat "based on photochemical modeling analyses showing thatthe formation ofozone in the BPA area is more sensitive to NOx than to VOC emissions, the increase inVOC emissions is expected to befully offset bythe decrease in NOx."
4-3Based on the photochemical modeling analysis included in the original 2008 BPA maintenance plan and supportedbythe EPA, emissions inthe BPA area are expected to remain at levels consistent with attainment for the 1997 eight-hour ozone standard through 2021. Please see Section 4.2:

### (No Change) 4.2.1.2 UpdatedVerification ofContinuedAttainment for Area Sources 

### (Added) In reviewing the 2008 BPA maintenanceplan and applying updates, staffdetermined that emissions wouldbe further decreased for bothNOx andVOC. There are two factors attributedto these reductions: updated growth factors providedbythe Eastern Research Group through a contract in 2010; 4 and speciation updates performed on the oil and gas categories for 2005. Although minorupdates have occurred in the area source category since the 2008 submission, those updates do not change the overall conclusions ofthe BPA maintenanceplan SIP revision. 4.2.2 On-RoadMobile Sources 

### (Updated) TheTexas Commission on Environmental Quality (TCEQ) updated the 2008 BP A maintenance plan's on-roadmobile source emissions inventoryestimates for this proposed SIP revision by contractingwith 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 ofthe EPA's MOVES model, MOVES2010a. The updated emissions inventory estimates include NOx andVOC emissions for the 2005 base year for the 2011, 2014, and 2017 interim years andfor the 2021 horizonyear. TTl also used the latest planning assumptions to develop the maintenance inventories in an effort to ensure that the MVEBs wouldbe consistent with transportation conformity analysis assumptions. TTl produced emissions estimates using a link-based methodology that used a travel demand model (TDM) andMOVES "rates-per-activity." Emissions were estimatedbyhourly and 24- hourperiodsbyMOVES source use type andfuel type, pollutantprocess, andTDM roadway class. The most recently available data were used, including Texas Department of Transportation (TxDOT) vehicle classification counts andTxDOT/Texas Department ofMotor Vehicles registration data. MOVES default data were used as needed. Control programs that were modeled in the analysis include:

• Federal MotorVehicle 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. Forthe fuel programs, MOVES defaults, fuel survey data, andfederally regulated values were used. Details ofhow these were modeled are found in Appendix D:

### (Updated) The 2008 BPA maintenance plan established MOBILE-based MVEBs, setting the allowable onroad mobile emissions that an area canproducewhile continuing to demonstrate maintenance. Local transportationplanning organizations demonstrate that projected emissions from transportationplans, programs, and projects are equal to orless thanthe MVEBs as requiredby thefederal transportation conformity rule. The NOx andVOC on-road mobile source emissions inventorytotals for 2021, the final year ofthis maintenanceplan, establish the MVEBs. The MOVES-based MVEBs for this proposed SIP revision are summarizedinTable 4-7:

### (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 theTexN model utilizes inputfiles andpost-processing routines to estimateTexas 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 maintenanceplan, was updatedto the NONROAD2oo8aversion in April 2009. The NONROAD2oo8a model accounted for the addition oftwo new federal rules that affect the equipment categories in the non-road mobile source sector; therefore, theTexN model was updated accordingly. In addition, equipment survey studies havebeen conducted and emissions updatedfor the diesel construction equipment sector, the agricultural equipment sector, and drilling rig diesel engines since 2009. Using current methodology andtheTexN/EPANONROAD2oo8a model, emissions calculated for each county in the BPA area are, overall, lower and demonstrate a downwardtrendfor both NOx andVOC comparedto the emissions reported inthe 2008 BPA maintenanceplan. Although minorupdates have occurred in the non-road mobile source category since the 2008 submission, those updates do not change the overall conclusions ofthe BPA maintenanceplan. 

### Airports The Federal Aviation Administration's Emissions and Dispersion Modeling System (EDMS) version 5.1 was used to estimate NOx andVOC emissions for commercial aircraft, general aviation, and ground support equipment emissions in the 2008 BPA maintenanceplan. The model has not changed since the 2008 submission, andthe repopulated EDMS files, which reflect 2011 operations, indicate thatboth"NOx andVOC emissions declinedbetween 2005 and 2011. The 2011 emissions calculated for the airports source categoryinthe BPA area demonstrate a downward trend for both NOx andVOC comparedto the emissions reported inthe 2008 BPA maintenanceplan. Although minorupdates have occurred in the airports source category since the 2008 submission, those updates do not change the overall conclusions ofthe BPA maintenanceplan. 

### Locomotives and CommercialMarine Vessels Texas Air Emissions Repository (TexAER) datafrom 2005, which was developed from the 2005 Consolidated Emissions Reporting Rule data, were used to estimate NOx andVOC emissions from locomotive and commercial marine vessel activities in the 2008 BPA maintenanceplan. The methodologyhas not changed since the 2008 submission. Actual 2011 emissions calculated for locomotive and commercial marinevessel activities in the BPA area, when comparedto theprojected 2011 emissions reported in the 2008 BPA maintenanceplan, are lower and demonstrate a downward trendfor both NOx andVOC. Since the original inventories conservatively estimatedfuture year locomotive and commercial marine vessel activities emissions, recalculation ofthe milestoneyear inventories would not change the overall conclusions ofthe 2008 BPA maintenance plan.

### shows that on-road mobile source emissions determined using the MOVES model account for a slightlylarger percentage ofNOx emissions, overall, than those determinedusing 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, thanthose 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 stationarypoint sources andthelargest 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 ofman-made emissions.

4·5 CONTINUED MAINTENANCEWITH MOVES-BASED ON-ROAD MOBILE EMISSIONS INVENTORIES (ADDED) Revising the on-roadmobile source emissions inventories and MVEBs for this proposed SIP revision would minimally affect projected NOx andVOC emissions trends from the 2005 base year across the 2011, 2014, and 2017milestone years andthe 2021 horizon year; however, NOx emissions are still projected to decrease andVOC 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 whetherto update inventories for the other source categories, TCEQ stafffound that area, non-road mobile, and stationarypoint source emissions all trended belowthe projections included in the 2008 BPA maintenanceplan. In addition, photochemical modeling analyses adoptedwith the 2008 BPA maintenance plan and supportedbythe EPA demonstrate that the formation ofozone in the BPA area is more sensitive to NOx than to VOC emissions. The slight increase inVOC emissions, which was shown in the original BPA maintenanceplan as well as this proposed update, wouldbe offset bythe decrease in NOx emissions. Those factors, along with the overall downward trendin ozone design values for the BPA area, showthatthis proposed SIP revision would continue to meet all requirements for maintenance ofthe 1997eight-hour ozone standard.

### Docket No.: 2012-o8os-SIP 

### Subject: Commission Approval for Adoption ofthe Beaumont-PortArthur (BPA) AttainmentArea On-Road Mobile Source Emissions Inventory and Motor Vehicle Emissions Budget (MVEB) Update State Implementation Plan (SIP) Revision BPA MVEB Update SIP Revision SIP Project No. 2012-005-SIP-NR 

### Background and reason(s) for the SIP revision: In 2008, the commission adoptedthe BPA area maintenance plan (Project No. 2008-oo6- SIP-NR), which demonstrates continued attainment ofthe 1997 eight-hour ozone standard through 2021. The planwas approvedbythe United States Environmental Protection Agency (EPA) effective November 19, 2010, andthe BPA area was redesignatedto attainmentfor 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 mustbe 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 ofMOVES-based MVEBs to replace the existing MOBILEbased MVEBs. The letter indicatedthatthe area was unable to conform to the existing MVEBs andwould enterinto a conformitylapse on September 25, 2012, which it has. The conformity lapse entails the cessation ofnewtransportation projects andproject phases until the area is able to conform to EPA-approved MVEBs. This SIP revision responds to the MPO's requestby establishing new MVEBs to which the BPA transportation plan may be able to conform. 

### Scope ofthe SIP revision: A.) 

### Summary ofwhat the SIP revision will do: This SIP revision replaces the 2008 BPA maintenance plan on-road mobile source emissions inventories for nitrogen oxides (NOx) andvolatile organic compounds (VOC) based on the EPA's MOBILE model with those based onthe 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 andVOC MVEBs are also updatedbased on the MOVES-based emissions inventories. This SIP revision includes documentation to satisfythe EPA's MOVES implementation policy guidance 1 

### concerning updating maintenance plans with MOVES, which indicates that states must (1) demonstratethatthe updatedplan 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 stationarypoint) continueto be valid and any minorupdates would not change the conclusions ofthe approved maintenance plan. B.) Scope required

### byfederal regulations or state statutes: For maintenance plans, MVEBs setthe maximum level ofon-road mobile transportation emissions that can be produced when consideredwith emissions from all other sources, which demonstrates continued maintenance ofthe National AmbientAir Quality Standards (NAAQS). Maintenance plans must include MVEBs for transportation conformitypurposes. Transportation conformity is requiredby Federal Clean Air Act (FCAA), §176(c) to ensure thatthe effects ofemissions from all on-road sources are consistentwith attainment or maintenance ofany criteria pollutant or its precursors allocatedto highway andtransitvehicle use. Conforming to the SIP means that transportation activities will not cause new air quality violations, worsen existing violations, orhinder maintenance ofthe NAAQS. The EPA's conformity rule, 40 Code of Federal Regulations Part 51.390 and Part 93 SubpartA, states that "conformity determinations mustbebased on the latest emission estimation model available." C.) 

### Additional staffrecommendations that are not required

### byfederal rule or state statute: On June 28, 2012, the TCEQ sent a letterto EPA, Region 6 requesting thatthe EPA parallel process its review and approval ofthis SIP revision with the TCEQ's. The EPA will consider a request to parallel process only when the state anticipates thatthere will be no significant changes madeto the associated SIP revision between proposal and adoptionbecause a notice ofproposed approval from the EPA could potentiallybe publishedbefore 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 BPA MVEB Update SIP Revision from the proposed version that was sentto 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 BPA-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,

2012. Although this SIP revision andthe EPA's expedited approval ofit could not prevent the transportation conformitylapse from occurring, these actions bythe commission and the EPA may help minimize the consequences ofthe lapse by shortening its duration. Statutory authority: 

### The authorityto 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 and7 andTexas Health and Safety Code, Chapter 382. Effect onthe: A.) 

### Regulated community: 

### The local transportation planning entities maybenefitfrom MOVES-based MVEBs by being able to proceed withplanning and initiating congestion-reducing transportation projects. B.) Public: 

### The general public couldbenefitfrom transportation improvement projects that decrease traffic congestion and emissions. C.) Agencyprograms: 

### This SIP revision has no neweffect on agency programs. Stakeholder meetings: 

### No stakeholder meetings were heldbecause there were no new rules associated with this SIP revision. Public comment: 

### The commission offered a public hearing in Beaumont onAugust 1, 2012. Notice ofthe publichearing was published in the 

### Texas Register andthe

### BeaumontEnterprise newspaper. The public hearingwas not openedbecause 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 andlegislative interest: 

### The transportation plan for the BPA arealapsed 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 notbe able to conform to MOVES-based MVEBs either. That would leave the area in a continuedtransportation conformitylapse until it adopts a new

### Commissioners Page4 October 26, 2012 Re: Docket No. 2012-0805-SIP transportation plan after the effective date ofrevocation oftransportation conformity requirements underthe 1997 eight-hour ozone standard, July 20, 2013. With revocation oftransportation conformity requirements under the 1997 standard and with an attainment/unclassifiable designation underthe 2008 standard, the BPA area would no longerbe required to demonstrate transportation conformity. This SIP revision may onlybeuseful, then, ifthe EPA finalizes approval andthe area demonstrates conformitybefore July 20, 2013. The TCEQ formally requestedthat the EPA parallel process its review and approval ofthis SIP revision to make it possible for the area to demonstrate conformityto MOVES-based, EPA-approved MVEBs as soon after commission adoption as possible andbefore July 20, 2013. Thatrequest was made on June 28, 2012, andthe EPA published its proposed approval in the

### FederalRegister on September 19, 2012 (77 FR 58058). 

### Does this SIP revision affect any currentpolicies or require development of newpolicies? No 

### What are the consequences ifthis SIP revision does not go forward? Are there alternatives to this SIP revision? The BPA-area transportation plan lapsed on September 25, 2012, after which no new transportation projects or project phases have been allowed to advance. Ifthe area is not able to conform to the existing maintenance MVEBs, transportation projects couldbe on hold until the area adopts a newtransportation plan after the effective date ofrevocation of transportation conformityrequirements under the 1997 eight-hour ozone standard, which is expectedJuly 20, 2013.

Project Number 2012-oos-SIP-NR

Adoption November 14,2012

### Thispage intentionally left blank

### EXECUTIVE SUMMARY In 2008, the commission adopted the Eight-Hour Ozone Redesignation Request and Maintenance Plan for the Beaumont-PortArthur (BPA) Ozone NonattainmentArea (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 ofthat standard through 2021. The planwas approvedbythe United States Environmental Protection Agency (EPA) effective November 19, 2010, andthe 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) andvolatile 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 MotorVehicle Emission Simulator (MOVES) model, to replace the MOBILE model for SIP applications. Beginning March 2, 2013, transportation conformity mustbe 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 TransitAdministration conform to the MVEBs established in the state implementation plan (SIP). Conformity mustbe demonstratedbefore area transportation plans can be approved orfunded by the United States Department ofTransportation orthe 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 determinationsby providing MVEBs based onthe MOVES2010a model. This SIP revision replaces the 2008 BPA maintenance plan on-road mobile source emissions inventories for NOx andVOC 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 andVOC MVEBs are updatedbased 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 stationarypoint) continue to be valid and any minor updates would not change the conclusions ofthe approved maintenance plan.

### SECTIONV-A: 

### LEGALAUTHORITY 

### General The Texas Commission on Environmental Quality (TCEQ) has the legal authorityto implement, maintain, and enforce the National AmbientAir 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 ofTexas, was passedbythe Texas Legislature in 1965. In 1967, the Clean Air Act ofTexas was supersededby a more comprehensive statute, the Texas Clean Air Act (TCAA), found inArticle 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 ofthe Texas Health and Safety Code. Originally, the TCAA stated thatthe 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 ofair resources. In 1991, the legislature abolished the TACB effective September 1, 1993, and its powers, duties, responsibilities, andfunctions were transferredto the Texas Natural Resource Conservation Commission (TNRCC). With the creation ofthe TNRCC, the authority over air quality is found inboththe Texas Water Code andthe TCAA. Specifically, the authority ofthe TNRCC is found in Chapters 5 and 7· Chapter 5, SubchaptersA- F, H

- J, and L, include the general provisions, organization, and general powers and duties ofthe TNRCC, and the responsibilities and authority ofthe 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 continuedthe existence of the TNRCC until September 1, 2013, and changed the name ofthe TNRCC to the TCEQ. In 2009, the 81st Texas Legislature, during a special session, amended section 5.014 ofthe Texas Water Code, changing the expiration date ofthe TCEQ to September 1, 2011, unless continued in existence bythe Texas SunsetAct. In 2011, the 82ndTexas Legislature continued the existence ofthe TCEQ until 2023. The TCAA specifically authorizes the TCEQ to establish the level ofqualityto be maintained in the state's air andto control the quality ofthe state's airbypreparing and developing a general, comprehensive plan. The TCAA, SubchaptersA-D, also authorize theTCEQ to collect information to enable the commission to develop an inventory ofemissions; 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, andpracticability and reasonableness; to conduct hearings; to establish air quality control regions; to encourage cooperation with citizens' groups and other agencies and political subdivisions ofthe state as well as with industries andthe federal government; and to establish and operate a system ofpermits for construction or modification offacilities. Local government authority is found in Subchapter E ofthe 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 ofthe TCEQ that affects their territorialjurisdiction, maybring 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 ofair pollution not inconsistent with the provisions of the TCAA and the rules or orders ofthe commission.

### Subchapters G and H ofthe TCAA authorize the TCEQ to establish vehicle inspection and maintenance programs in certain areas ofthe state, consistent with the requirements ofthe Federal Clean Air Act; coordinate with federal, state, andlocal 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; andfund and authorize participating counties to implementvehicle repair assistance, retrofit, and accelerated vehicle retirement programs.

### CHAPTER1: 

### GENERAL(UPDATED) 1.1 BACKGROUNDAND INTRODUCTION 

### (UPDATED) In 2008, the commission adopted the Eight-Hour Ozone Redesignation Request and Maintenance Plan for the Beaumont-PortArthur (BPA) Ozone NonattainmentArea (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 ofthat standard through 2021. The planwas approved bythe 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) andvolatile 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 andVOC 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, andprojects funded bythe Federal Highway Administration orthe Federal TransitAdministration do not exceed the MVEBs established in the SIP. Conformity mustbe demonstratedbefore area transportation plans can be approved or funded by the United States Department ofTransportation or area metropolitan planning organizations (MPOs). The MVEBs established in the 2008 BPA maintenance plan were based onthe mobile source emissions estimation model in use atthattime, the EPA's MOBILE model. On March 2, 2010, the EPA officially released a new mobile source emissions estimation model, the MotorVehicle Emission Simulator (MOVES) model, to replace the MOBILE model for SIP applications. Beginning March 2, 2013, transportation conformity mustbe 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 ofMOVES-based MVEBs to replace the existing MOBILE-based MVEBs. The letter indicated that the area was unable to conform to the existing MVEBs andwould enter into a conformity lapse on September 25, 2012, which it has. The conformitylapse entails the cessation ofnew transportation projects and projectphases until the area is able to conform to EPA-approved MVEBs. This SIP revision responds to the MPO's request byestablishing new MVEBs to which the BPA transportation plan maybe able to conform. 1.1.1 Purpose ofPlan 

### (Updated) This SIP revision replaces the 2008 BPA maintenance plan on-road mobile source emissions inventories for NOx andVOC 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 andVOC 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 ofthe approved maintenance plan.

### Eight-Hour Ozone History 

### inthe 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 primaryeight-hour ozone standardin the range ofo.o6o to 0.070 

### ppm. On September 2, 2011, 

### the President announced a request thatthe EPA withdraw the proposed, reconsidered ozone standard. In a September 2011 

### memo, the EPA announcedthat itwould proceed with initial area designations underthe 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 ofdesignations underthe 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 conformitywill no longer be required as ofJuly 20, 2013.

### Ozone Data (No Change) 2.1.2 

### Ozone TrendAnalysis (Updated) Ozone trends in the Beaumont-PortArthur (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 decreasedby 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 perbillion (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 andPopulation Trends in the BPAArea. Figure 2-3: 

### Ozone Exceedance Days andNumber of Monitors in the BPAArea shows that the number ofeight-hour ozone exceedance days has decreased in the BPA area despite an increase in the number ofmonitors. Although therewere more eight-hour ozone exceedance days in 2011 

### comparedto 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 ofdays that favored the development ofozone. Because the exceedance day count is dependent on the number ofmonitors in the area, the number ofeight-hour ozone exceedance days by monitor is shown in Figure 2-4: 

### Eight-Hour Ozone Exceedance Days byMonitor in the BPAArea

. Exceedances by monitortend to vary from year to year; however, the overall trend in the number ofeight-hour ozone exceedance days has been decreasing over the past 20 

### years.

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

### AverageNOx Trends in the BPAArea shows the NOx trends atfive monitors in the BPA area: Beaumont Downtown (CAMS 2/CAMS 112/ CAMS 2002), Jefferson CountyAirport (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 ofthe 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 lastyear 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 of54%. 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.

### 2.3.3.2 Volatile Organic Compounds Trends 

### (Updated) Continuous volatile organic compounds (VOC) data are collected at two automated gas chromatograph (AutoGC) monitors in the BPA area. Those two monitors are Beaumont Downtown (CAMS 2/CAMS 112/ CAMS 2002) and Nederland High School (CAMS 1035), which have valid databeginningAugust 28, 2006, andAugust 29, 2006, respectively, and ending on December 1, 2011. Note that the last month ofdata from 2011 is notyet available. Figures 2-6: 

### Median Ethylene atAutoGCs in the BPAArea and 2-7: 

### Median Propylene atAutoGCs in the BPAArea showthe 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 1035).

### inthe BPAArea 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 Trendsfrom Canister Data in the BPAArea and 2-9: 

### Median Propylene Trends from Canister Data in the BPAAreaboth show that ethylene and propylene, two ofthe 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 ofdata 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 atthe nine canister sites (one ofthe eight sites has three monitors), with an average decrease of41%. 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 onlybeen 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, butit has onlybeen in operation for two years. Forbothpropylene and ethylene, the increase at Beaumont Mary (CAMS 1050) was less than 0.5 ppb.

### CHAPTER4: MAINTENANCE DEMONSTRATION (UPDATED) 

### 4.1 GENERAL (UPDATED) 

### This state implementation plan (SIP) revision is an update to the 2008 

### Beaumont-PortArthur (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) tobe based onthe United States Environmental Protection Agency's (EPA) MotorVehicle Emission Simulator (MOVES) model. The on-road mobile source emissions inventories and MVEBs adopted with the 2008 

### BPA 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 mustbe 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 oftheir 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 bevalid and any minor updates would not change the conclusions ofthe approved maintenance plan. This SIP revision satisfies both conditions ofthe MOVES guidance document; therefore, only Section 4-4.2: 

### On-RoadMobile Sources has been revised. For each ofthe other source categories (area, non-road mobile, and stationarypoint), sections have been added describing that any minor updates have not changed the conclusions ofthe 2008 

### BPA maintenance plan: Section 4.2.1.2: 

### Updated Verification ofContinuedAttainmentforAreaSources; Section 4.2.3.3: 

### Updated Verification ofContinuedAttainmentforNon-RoadMobile Sources; and Section 4.2-4-4: 

### Updated Verification ofContinuedAttainmentforStationary Point Sources. 4.2 FU1URE EMISSIONSANDVERIFICATION OF CONTINUEDATTAINMENT (UPDATED) 

### MOVES-based on-road mobile source NOx andVOC emissions estimates change slightly from the MOBILE-based estimates adopted with the 2008 

### BPA maintenance plan. Table 4-1: 

### MOBILE-Based On-RoadMobile Source NOx and VOCEmissions in the BPAArea (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 stationarypoint sources were not included in Table 4-1 

### because theywere 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 ofNOxEmissions in BPA by Source Type (2005, 2011,2014,2017, 

### and 2021)

Updatingthe 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 inVOC over the 16 years projected for the BPA maintenance plan, it hasbeen established that NOx emissions reductions are more effective thanVOC reductions at reducing ozone design values in the BPA area. In fact, photochemical modeling analysis adopted with the 2008 BPA maintenance plan showedthat 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 ofthe 2008 plan in the

### Federal Register (75 FR 27514), the EPA supportedthe 2008 demonstrationby stating that "based on photochemical modeling analyses showing that the formation ofozone in the BPA area is more sensitive to NOx than to VOC emissions, the increase inVOC emissions is expected tobe fully offset bythe decrease in NOx."

### Based on the photochemical modeling analysis included in the original 2008 BPA maintenance plan and supportedby the EPA, emissions in the BPA area are expected to remain atlevels consistent with attainment for the 1997 eight-hour ozone standard through 2021. Please see Section 4.2:

### (Added) In reviewing the 2008 BPA maintenance plan and applying updates, the TCEQ determined that emissions wouldbefurther decreased for both NOx andVOC. There are two factors attributed to these reductions: updated growth factors providedbythe 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 ofthe BPA maintenance plan SIP revision. 4.2.2 

### On-RoadMobile Sources (Updated) 

### The Texas Commission on Environmental Quality (TCEQ) updatedthe 2008 BPA 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 BPA counties, Jefferson, Hardin, and Orange, using the newest version ofthe EPA's MOVES model, MOVES2010a. The updated emissions inventory estimates include NOx andVOC emissions for the 2005baseyear, the 2011, 2014, and 2017 interimyears, andthe 2021 horizon year. TTl also used the latestplanning assumptions to develop the maintenance inventories in an effort to ensure that the MVEBs wouldbe consistent with transportation conformity analysis assumptions. TTl produced emissions estimates using a link-based methodologythat used a travel demand model (TDM) and MOVES "rates-per-activity." Emissions were estimatedby hourly and 24- hour periodsby MOVES source use type andfuel type, pollutantprocess, and TDM roadway class. The most recently available data were used, including Texas Department of Transportation (TxDOT) vehicle classification counts and TxDOT/Texas Department ofMotor Vehicles registration data. MOVES default data were used as needed. Control programs that were modeled in the analysis include:

• Federal MotorVehicle 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. Forthe fuel programs, MOVES defaults, fuel survey data, and federally regulated values were used. Details ofhow these were modeled are found in Appendix D:

### MotorVehicle 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, andprojects are equal to orless than the MVEBs as requiredby the federal transportation conformityrule. The NOx andVOC on-road mobile source emissions inventorytotals for 2021, 

### the final year ofthis 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 usingMOVES2010a. Detailed documentation ofMVEB calculations, modeling methods, and input parameter development and usage is provided inAppendix D. Table 4-7:

### (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 thebasic 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 inApril 2009. The NONROAD2oo8a model accounted for the addition oftwo new federal rules that affect the equipment categories inthe non-road mobile source sector; therefore, the TexN model was updated accordingly. In addition, equipment survey studies have been conducted and emissions updatedfor the diesel construction equipment sector, the agricultural equipment sector, and drilling rig diesel engines since 2009. Using current methodology andthe TexN/EPA NONROAD2oo8a model, emissions calculated for each county in the BPA area are, overall, lower and demonstrate a downward trend for both NOx andVOC 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 ofthe BPA maintenance plan. Airports The FederalAviation Administration's Emissions and Dispersion Modeling System (EDMS) version 5.1 was used to estimate NOx andVOC emissions for commercial aircraft, general aviation, andground support equipment emissions in the 2008 BPA maintenance plan. The model has not changed since the 2008 submission, andthe repopulated EDMS files, which reflect 2011 operations, indicate thatboth NOx andVOC 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 andVOC comparedto the emissions reported in the 2008 BPA maintenance plan. Although minorupdates have occurred in the airports source category since the 2008 submission, those updates do not change the overall conclusions ofthe BPA maintenance plan. Locomotives and CommercialMarine 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 andVOC 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 andVOC. Since the original inventories conservatively estimated future year locomotive and commercial marine vessel activities emissions, recalculation ofthe milestone year inventories would not change the overall conclusions ofthe 2008 BPA maintenance plan.

### (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 arebelow the 2005 base year emissions, below emissions trends projected in the maintenance plan, and are anticipated to remainbelowprojected emissions. Since the original inventories conservatively estimatedfuture year point source emissions, recalculation ofthe milestone year inventories would not change the overall conclusions ofthe 2008 BPA maintenance plan. 

### 4·3 CONTROL STRATEGIES (NO CHANGE) 

### 4·4 EMISSIONS SUMMARY (UPDATED) 

### Updated percentages ofemissionsby source category for 2005, 2011, 2014, 2017, and 2021 are reflected in Tables 4-8: 

### UpdatedPercentages ofNOxEmissions in BPA by Source Category and 4-9: 

### UpdatedPercentages 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 slightlylarger 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 determinedusing the MOBILE model. As 

### in the 2008 BPA maintenance plan, these tables showthatthe largest man-made contribution of NOx is from stationarypoint sources andthe largest man-made contribution ofVOC is from area sources. Contributions from biogenic emissions are not included in the summarybecause the maintenance measures are limited to the reduction ofman-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 andVOC emissions trends from the 2005

### baseyear across the 2011, 2014, 

### and 2017 

### milestone years and the 2021 

### horizon year; however, NOx emissions are still projected to decrease andVOC emissions are still projectedto 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 stationarypoint source emissions all trendbelowthe projections included in the 2008 

### BPA maintenance plan. In addition, photochemical modeling analyses adopted with the 2008 

### BPA maintenance plan and supportedbythe EPA demonstrate that the formation ofozone in the BPA area is more sensitive to NOx than to VOC emissions. The slight increase inVOC emissions, which was shown in the original BPA 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, showthatthis SIP revision continues to meet all requirements for maintenance ofthe 1997

### eight-hour ozone standard.
