### Component # 1 (this component was evaluated by S. Rennie) : What is EPA’s Voluntary Mobile Emission reduction Program (VMEP)?3 Voluntary mobile source strategies that attempt to complement existing regulatory programs throu gh voluntary, non

- regulatory changes in local transportation activities or changes in in

- use vehicle and engine composition constitute the VMEP. EPA supports innovative methods in achieving air quality goals and the creation of viable voluntary mobile sou rce air quality programs. The increasing cost of technological improvements to produce incrementally smaller reductions in grams per mile or grams per kilowatt

- hour emission in the entire fleet of vehicles and engines suggests that supplemental or alterna tive approaches for reducing mobile source air pollution are necessary.
The C AA allows SIP credit for new approaches to reducing mobile source emissions. This flexible approach is set forth in section 110 of the Act, and economic incentive provisions are in sections 182(g)(4)(A) and 108 of the Act. The credits generated through VMEP can be counted toward attainment and maintenance of the NAAQS. Up to 3% of the total future year emissions reductions of each pollutant required to attain the appropriate NAA QS may be claimed under the VMEP. Some voluntary mobile measures may also be implemented under authority of the Economic Incentives Program What are the guidelines for creditability of emission reductions achieved under a VMEP?
The basic framework for ens uring SIP credit for VMEPs is spelled out in guidance issued under a memorandum from Richard D. Wilson, Acting Assistant Administrator for Air and Radiation, dated October 24, 1997, entitled “ Guidance on Incorpo rating Voluntary Mobile Source Emission Reduction Programs in State Implementation Plans (SIPs) .” While this guidance was l ater inco rporated into another EPA guidance, “Implementing Bundled Measure into a State i mplementation Plan (SIP),” 1 the VMEP demonstration is based on the former and the mobile source portion of the latter. Generally, to obtain credit for a VMEP, a State submits a SIP that: 1) identifies and describes a VMEP; 2) contains projections of emission reductions attributable to the program, along with any relevant technical supp ort documentation; 3) commits to evaluation and reporting on program implementation and results; and 4) commits to the timely remedy of any credit shortfall should the VMEP not achieve the anticipated emission reductions. More

1 Office of Air and Radiation, August 2005.4 specifically, the guidance suggests the following key points are considered for approval of credits. The credits should be:
1. Quantifiable

- VMEP emission reductions must be quantifiable. The level of uncertainty in achieving emission reductions must be quantified, and this unce rtainty must be reflected in the projected emission reductions claimed by the VMEP. VMEPs must also contain procedures designed to both evaluate program implementation and to report program results as described in the “Technical Support for VMEPs” portion of the guidance.
2. Surplus

- VMEP emission reductions may not be substituted for mandatory, required emission reductions. States may submit to EPA for approval any program that will result in emission reductions in addition to those already credited in a relevant attainment or maintenance plan, or used for purposes of SIP demonstrations such as conformity, rate of progress, or emission credit trading programs.
3. Enforceable

- VMEPs must be enforceable at the State and Federal levels. A State can adop t a measure into the SIP such that the State is obligated only to track, assess and report on the implementation of voluntary actions and the emission reductions achieved from the voluntary actions. The State is not responsible, necessarily, for implement ing a program depending on voluntary actions. The State must commit to conducting program evaluations and reporting the results to EPA within an appropriate time

- frame.
4. Permanent

- VMEP emission reductions must continue at least for as long as the time period in which they are used by the applicable SIP demonstration.
5. Adequately Supported

- VMEPs must demonstrate adequate personnel and program resources to implement the progra m.
6. Consistent
- VMEPs must be consistent with attainment of the standard and with and Rate of Progress requirements. Further, VMEPs cannot interfere with the other requirements of the Clean Air Act. What is the Background for the HGB VMEP Program?5 The State first established the VMEP program in the December 2000 1

- hour ozone attainment demonstration for the HGB nonattainment area approved by EPA on November 14, 2001, 66 FR 57160. In that initial action we approved VMEP emission reductions of 23 tpd of NOx (up to 3% of the total needed for attainment) because the state was able to demonstrate that the HGB area’s ozone SIP VMEP met the criteria for credit in the SIP. The State showed that the credits were quantifiable, surplus, enforceable, permanent, adequately supported, and consistent with the SIP and the Act. The Houston

- Galveston Area Council (H

- GAC) implemented the VMEP programs in the HGB area, committing to evaluate each program to validate estimated credits, and reporting the emission reductio ns to the TCEQ. The State is responsible for verifying the reported emissions and timely remedy of any shortfall. The VMEP program can be revised by submitting substitute measures or additional measures as a SIP revision, which has been done with subsequ ent submittals.
In the mid

- course review submitted December 1, 2004, it was noted that the VMEP program was not getting the projected 23 tpd in NOx reductions. Subsequently, we approved that revision and a supplemented VMEP program on September 6, 2006, 71 FR 52656, which revised credit taken for this program to 7 tpd. In that revision, certain mobile emission credits were recalculated using MOBILE6. In the earlier SIP submittal these credits were calculated using MOBILE5a.
What did the State submit?
In the June 13, 2007 , submittal adopted May 23, 2007, the State includes seven program descriptions (Table B ) that project emission reductions attributable to each voluntary commitment as part of the Houston

- Galveston

- Brazoria State Implementation Plan. Thi s submittal builds upon the VMEP program established in previous SIP revisions as noted above. The additional commitment to reduce NOx by an estimated 2.82 tons per day, and are referred to as the Houston

- Galveston Area Council (H

- GAC) reductions.

- Expanding Vanpooling

- Internet Ridematching Service and Incentives

- Personalized Rapid Transit and Subscription Service 0.77

Pooled Ownership of Vehicles 0.05 Total Benefits 2.82 All VMEP commitment emission reductions were calculated for 2009 and were not to be forecasted to estimate emission reductions for any other year. The measures will be in place for the life of the SIP, however, which makes them permanent.
What did EPA’s analysis show? Overall the VMEP projects are consistent with the SIP and fall within the 3% allowed by the guidance for voluntary mobile measures. None of the programs interferes with or are mandated by other Act requirements. Employee trip reduction i s no longer required by the Act, so the Commute Solutions measures are allowed. Therefore all programs are surplus.
Since the State committed in the December 2000 SIP to assure that any shortfall in VMEP credits would be made up with other measures not already in the SIP, the measures are enforceable. And since all measures will be in place by 2009 for a 2010 attainment date , and they will remain in place for the life of the SIP, the measures are considered permanent. Our analysis below further shows that each program is also quantifiable and adequately supported. Therefore all criteria for the VMEP have been met

. Publi c and Private Sector Clean Fuel Fleet : A description of this measure is found in Appendix A of the submittal, Voluntary Mobile Source Emission Reduction Programs for the Houston

- Galveston

- Brazoria Eight

- Hour Ozone State Implementation Plan. This measure s eeks to reduce on

- road vehicle emissions through rapid turnover to newer, lower emitting engines, retrofit of existing engines with approved devices, or new, lower emission technologies. The target for this program will be heavy duty vehicles,7 although oth er fleets can compete for the funds. Funding heavy duty vehicles is more cost effective than lighter vehicles. Funding for the program comes from CMAQ and TERP. Quantifying the emission reductions from this program is done by calculating the differences in emission standards for vehicles that are replaced by new, lower emission vehicles, or by using EPA’s diesel emission quantifier for calculating benefits of retrofits and other new technologies. Therefore, the state has demonstrated that this program m easure is quantifiable and adequately supported. The emission reductions for this program are projected to be 2.0 tpd of NOx.
Commute Solutions Summary descriptions of the Commute Solutions program Detailed descriptions of the five programs that make up C ommute Solutions are found in Appendix A cited above. Detailed descriptions are found in Appendix C, Evaluation of Mobile Source Control Strategies for the Houston

- Galveston

- Brazoria State Implementation Plan (Drafted by Environ for the Houston

Galveston Area Council), of the submittal. The combined emission reduction for all Commute Solutions programs is projected to be 0.77 tpd of NOx. Compressed Work Week : A compressed work week program is already in place in the HGB nonattainment area, but this

measur e would aim to specifically increase the amount of compressed work weeks through a mandatory program that is not currently in place. This program would target 20% of Houston area employees for a 4/40 program (four 10 hour days per week). Emission reducti ons are calculated using the MOSERs 2 method that takes into account variables for number of employees potentially affected, average round trip VMT, average light duty vehicle composite emission factors for NOx and VOC. Although costs for this hypothetical program are unknown, the cost to employers is considered minimal with offsetting benefits including decreased turnover, reduced parking demand, and possibly fewer sick days. The cost effectiveness of the program is approximately $4,200/ ton of NOx reduce d. The analysis shows that this measure is quantifiable and could be adequately supported.

2 Mobile Source Emission Reduction Strategi es. http://moser.tamu.edu/8 Telecommuting Incentives or Mandates : A telecommuting program is already in place in the HGB nonattainment area with varying frequency, but this measure would aim t o specifically increase the amount of telecommuting through a program that is not currently in place in which an employee would commit to tele

working once per week. The program would target 10% of the total employment in the HGB nonattainment area. Emis sion reductions are calculated using the MOSERs method that considers the average round trip VMT per participant, one day per week participation, and average light duty vehicle composite emission factors for NOx and VOC. The current program costs attribut ed to employer outreach and marketing by H

- GAC and consultants is $2.5 million/year. Although this program aims to be 100 times larger than the current program, an accurate cost cannot be calculated, and it is assumed that an addition $2.5 million would b e allocated for the new program. Net benefits are not quantified, but may be as much as three times the program cost based on a JALA International example. Cost

- effectiveness is about $6,400/ton of NOx reduced. The analysis shows that this measure is qu antifiable and could be adequately supported. Expanding Vanpooling : The ongoing vanpooling program is anchored by METRO (the local transit agency), and consists of standard vanpools and a newer effort called “miniPOOL” to recruit participants. The aim of this measure would be to aggressively encourage vanpooling through improved coordination and implementation of the program, additional funding and improved marketing outreach. The goal is to increase ridership by three times the current number. The net d ecrease in VMT would be over 1million miles per day. Emission reductions are calculated using MOSERs methodology. Reductions are reduced by an additional 0.4 tpd from reductions already accounted for in the baseline modeling. Some of the additional cost of the program may be offset by “the application of revenue positive features such as limited in

- van advertising.” The cost

- effectiveness is estimated at about $36,700/ton of NOx reduced. The analysis shows that this measure is quantifiable and could be adequately supported. Internet Ridematching Service and Incentives :9 This program is described as an H

- GAC ridesharing program that uses computer

- based methods to match riders for carpooling. It was started in August 2005. This program offers incentives to participate by offering gift cards and other similar benefits to participants based on the number of times they sign up for a carpool. The aim of this measure is to increase participation in the program from its infancy of 2,500 riders to 100,000 regul ar riders who would use this service on average two times per week. This program is available seven days a week, and so can provide additional reductions that other commuter programs would not ordinarily do. The VMT reductions are calculated with MOSERs methodology using the number of ridesharers, miles of carpooling, miles driven by the carpool driver, and frequency of ridesharing. A budget of $1.5 million is expected to be sufficient to accommodate the larger ridership. Sign up for the program is free to the riders, so the program cost must be borne by H

- GAC. The cost

- effectiveness is about $15,200/ton of NOx reduced. The analysis shows that this measure is quantifiable and could be adequately supported. Personalized Rapid Transit and Subscription Se rvice : This innovative program would be designed to remove obstacles to transit use by providing more personalized services between residential areas and employment areas. This might include on

line transit planning, subscription bus service, and feeder s huttles from major transit stops to work centers. Buses and vans may be equipped with wireless Internet connections and accommodate working in transit with fold

- down tables. The analysis envisions 100 business buses and 100 shuttle buses. The program ar ea would include underserved residential areas too far from transit center or park and ride and employment areas in downtown Houston which do not have sufficient transit access. Calculation of emission reductions is by MOSERs methodology that relied on t he following key variables:

• 100 buses seating 35 people operating four round trips (per person) per day; at 80% capacity this is equivalent to 11,200 people per work day;

• 100 shuttle buses seating 15 people operating 6 round trips (per person) per day; a t 80% capacity this is equivalent to 7,200 people per work day.10 • 100% of shuttle use is due to new transit users who did not previously use transit because it did not provide a viable way to their place of employment or their home.

• average work trip dista nce is 40 miles round trip business buses travel 40 miles for each round trip, or 160 miles each day per bus; new emissions due to these buses is therefore based upon an average weekday mileage of 16,000 miles.

• shuttle buses are assumed to travel 10 miles per round trip, or 60 miles per day per shuttle; new emissions due to the shuttles is therefore based upon an average weekday shuttle mileage of 6,000 miles.

• Average light duty vehicle composite emission factor for NOx for same day is 0.471 grams per mil e

• Average light duty vehicle composite emission factor for VOC for same day is 0.489 grams per mile.

• Average shuttle bus emissions are represented by the MOBILE6 category LDDT12 and are 2.68 grams per mile of NOx and 2.56 grams per mile of VOC.

• Average transit bus emissions are represented by the MOBILE6 HDDBS category and are 9.83 grams per mile NOx and 0 .57 grams per mile VOC. The cost of the program is estimated at over $45.6 million/year (in 2005

- 2006 $) not including marketing and administration. R iders will pay $2 to $5 per round trip. Selling ad space inside the vehicles will also be considered as a way to help pay for the service. Annual NOx reduction benefits are 54.6 tons, with cost effectiveness at $500,000/ton. The analysis shows that this measure is quantifiable and could be adequately supported. Pooled Ownership of Vehicles A detailed description of this program is found in Appendix C, Evaluation of Mobile Source Control Strategies for the Houston

- Galveston

- Brazoria State Implementation P lan (Drafted by Environ for the Houston

- Galveston Area Council), of the submittal. This is a car

- sharing program with vehicles based at transit stations for use by employees to dispersed work locations. These vehicles are referred to as station cars. Th e analysis assumes 10,000 station cars used by 10 people per car. Calculation of the emission reduction from VMT by this program was done using the basic process suggested by the MOSERs methodology. Depending on how the program is structured, the cost pe r ton of NOx could range from $0 to $14,000. The cost would be borne by the station car users, and some other entity (presumably H

- GAC) for marketing and11 administration. This measure was estimated to provide 0.05 tpd of NOx reductions. The analysis show s that this measure is quantifiable and could be adequately supported.
Conclusion for Component # 1 : The HGB 8

- Hour SIP revision of the VMEP meets the criteria for credit in the SIP. The State has shown that the credits are quantifiable, surplus, enforceab le, permanent, adequately supported, and consistent with the SIP and the Act. We recommend proposing approval of the VMEP portion of the HGB 8

What EPA document contains a list of questions and answers concerning relationship of the 1
- Hou r RACT and the 1997 8
- Hour RACT? The May 18, 2006 Memorandum from William T. Harnett, Director, Air Quality Policy Division to Regional Air Division Directors titled “RACT Qs & As

– Reasonably Available Control Technology (RACT): Questions and Answers” (EPA’s May 18, 2006 RACT Q and A document ) explains the relationship of the 1

- Hour RACT and the 1997 8

- Hour RACT in the form of a series of questions and answers. This document is available at http://www.epa.gov/ttn/oarpg/t1/memoranda/ractqanda.pdf (URL dating June 12, 2012)

. What Framework did Texas use to conduct its RACT analysis?
Texas submitted a RACT assessment in its SIP revision s of June 13, 2007 and April 6, 2010. In th ose submittal s , Texas evaluated its existing RACT regulations which were federally approved and adopted to meet the 1

- hour ozone standard to ascertain whether the se regulations constitute RACT for the new 8

- hour ozone NAAQS. Texas’ 8

- H our ozone RACT SIP submittal s are based on the determination that RACT has been met either through a certification that previously required RACT controls for the 1

- hour ozone standard represent RACT for 8

- hour ozone implementation purposes or, where necessary, through a new RACT evaluation for certain regulatio ns or sources. See section 3.3.2 of Appendix D, April 6, 2010 submittal. In making its 8

- H our ozone R ACT determination, Texas also relied on EPA’s May 18, 2006 RACT Q and A document

. See section 3.3 of Appendix D, April 6, 2010 submittal. A ccordingly, the framework for Texas’ RACT SIP determination is to :16 • Identify all source categories covered by Control Technique Guidelines (CTG) and Alternative Control Technique (ACT) documents.

• Identify applicable regulations that implement RACT.

• Certify that the existing level of controls for the 1

- hour ozone standard equals RACT under the 8

- hour ozone standard, or

• De clare that sources covered by a CTG and ACT do not exist within the state and/or that RACT is not applicable in certain cases , or

• Identify potential RACT revisions necessary to implement RACT

.
What is our review of Texas’ RACT analysis ? By approving RACT under the 1

- Hour ozone standard ( 70 FR 58136, October 5, 2005; and 71 FR 52676, September 6, 2006 ) we found that control measures in 30 TAC Chapter 115 meet the lowest emissions limitation that a particular source is capable of meeting by the application o f control technology that is reasonably available, considering technological and economic feasibility

. EPA’s May 18, 2006 RACT Q and A document recommends a State certif y after review that its regulations continue to represent RACT fo r the 1997 8

- Hour ozon e NAAQS. Th e certification approach is in agreement with the 70 FR 71612, November 29, 2008 (Final Rule to Implement the 8

- Hour Ozone NAAQS). Also, see sections 3.1 and 3.3, Appendix D, April 6, 2010 submittal. The most recent revisions to Chapter 115 reg ulations corresponding to the newly

– 219

Section 115.211 affects the Houston/Galveston areas requiring a VOC limit of 0.09 pound per 1,000 gallons (10.8 mg/liter) of gasoline loaded into transport vessels.17 Section 115.212 concerns control requirements for nonattainment areas including the HGB area and the vapors from the transport vessel caused by the loading of VOC with a true vapor pressure greater than or equal to 0.5 psia under ac tual storage conditions must be controlled by at least a control efficiency of 90%, a vapor balance system, or a pressurized loading system. Section 115.213 provides for an alternative means control for VOCs and facilitates operational; flexibility for op erations. Section 115.214 provides for inspection requirements of the affected VOC loading and unloading sources in the HGB area ranging from visible liquid leaks, visible fumes to significant odors and prescribes what action to take. Section 115.215 estab lishes what Test Methods are to be used to determine compliance. Some of these Test methods are: Flow rate. Test Methods 1

- 4 (40 Code of Federal Regulations (CFR) Part 60, Appendix for determining flow rates, as necessary; Test Method 18 (40 CFR Part 60, A ppendix A) for determining gaseous organic compound emissions by gas chromatography; Test Method 25 (40 CFR Part 60, Appendix A) for determining total gaseous non

- methane organic emissions as carbon; Test Methods 25A or 25B (40 CFR Part 60, Appendix A) fo r determining total gaseous organic concentrations using flame ionization or non

- dispersive infrared analysis. Adoption of these approved Test Methods will provide for federally enforceable mechanism for Chapter 115.

Section 115.112 establishes the control requirements based on the true vapor pressure and tank capacity of the storage tank when VOCs Other than Crude Oil and Condensate are stored. See Table 1(a) of this section. Also establishes the control requirement s based on the true vapor pressure and tank capacity of the storage tank when crude oil and condensate are stored in a tank. See Table II(a) of this section. This section also states that when a vapor control systems is used28 as a control device on any sto rage tank must maintain a minimum control efficiency of 90%. If a flare is used, it must be designed and operated in accordance with 40 Code of Federal Regulations §60.18(b)

- (f) (as amended through December 22, 2008 (73 FR 78209)) and be lit at all times when VOC vapors are routed to the flare. Section 115.113 provides for an alternate methods control condition upon demonstrating and documenting continuous compliance with the applicable control requirements or exemption criteria as the case might be. This provision provides for operational flexibility to a source. Section 115.114 establishes what the inspection requirements for each affected tank are. This provision should facilitate compliance determination. Section 115.115 set forth the parameters an aff ected source in the HGB area will need to monitor. For example, for a direct

- flame incinerator, the owner or operator shall continuously monitor the exhaust gas temperature immediately downstream of the device; for a condensation system, the owner or opera tor shall continuously monitor the outlet gas temperature to ensure the temperature is below the manufacturer's recommended operating temperature for controlling the volatile organic compounds (VOC) vapors routed to the device; and for a carbon adsorption system or carbon adsorber the owner or operator shall continuously monitor the exhaust gas VOC concentration of a carbon adsorption system that regenerates the carbon bed directly to determine breakthrough (using EPA Test Method 21). These monitoring requi rements will facilitate compliance determination. Section 115.116 establishes the testing requirements for an affected facility in the HGB area. For example; for a vapor control system, other than a vapor recovery unit or a flare, an initial control effici ency test must be conducted in accordance with the approved test methods; and when A flare used to comply with the control requirements it must meet the design verification test requirements in 40 CFR §60.18(f) (as amended through December 22, 2008 (73 FR 78209)). In addition, if the vapor control system is modified in any way that could decrease the control efficiency of the system, then the device must be retested within 60 days of the modification. Section 115.117 set forth what test methods are to be u sed to determine compliance with emission specification or prescribed VOC control level. Among these tests are EPA Test Methods 1

- 4 for determining the flow rate, Test methods 18, 21, 22, 25, 25A, and 25 B. In addition, true vapor pressure must be determin ed using standard reference texts or American Society for Testing and Materials Test Method D323, D2879, D4953, D5190, or D5191 for the29 measurement of Reid vapor pressure, adjusted for actual storage temperature in accordance with American Petroleum Instit ute Publication 2517. Use of approved test methods will facilitate compliance determination. Section 115.118 establishes specific equations to determine reportable emissions, and states that all records must be maintained for two years and be made availab le for review upon request by authorized representatives (including any local air pollution control agency with jurisdiction). Section 115.119 establishes the date by which an affected source in the HGB area is to meet the applicable recordkeeping, monitor ing, testing, and emission specifications requirements of this sector. The compliance schedule will make this particular provision of Chapter 115 federally enforceable. Sections 115.112

- flame incinerator the conditions are at a temperature equal to or greater than 1,300 degrees Fahrenheit (704 degrees Celsius); a smokeless flare; or any other vapor control system are to be used. Establishing a minimum control requirement should assist in lowering the VOC in the affected area. Section 115.313 provides for an alternate methods control condition upon demonstrating and documenting continuous compliance with the applicable control requirements or exemption criteria as the case might be. This provision provides for operational flexibility to a source. Section 115.315 set forth what test methods are to be used to determine compliance with emission specification or prescribed VOC control level. Among these tests are EPA Test Method s 1

- 4 for determining the flow rate, Test methods 18, 25, 25A, and 25 B for determining concentrations. Use of approved test methods will facilitate compliance determination. Section 115.316 sets forth what parameters are to be monitored and what records a re to be maintained. All records shall be maintained for two years and be made available for review upon request. Among such records are: continuous monitoring of the exhaust gas temperature immediately downstream of a direct

- flame incinerator; continuous monitoring of temperatures upstream and downstream of a catalytic incinerator or chiller; continuous monitoring of the exhaust gas VOC concentration of any carbon adsorption system; and the results of any applicable testing conducted. Maintaining records a nd making them available for review or examination will assist with compliance determination. Section 115.317 states what source may be exempt from these requirements. The only exemption is listed is for the vacuum

- producing system emitting a combined weig ht of volatile organic compounds equal to or less than 100 pounds (45.4 kg) in Gregg, Nueces, and Victoria Counties. No exemption is listed in this source category within the HGB area. Section 115.319 establishes what counties are subject to these require ments and by what date an affected source should comply with the applicable control requirements of the process unit turnaround and vacuum

- producing systems in petroleum refineries. For compliance date see 115.930.31 Section 115.131 establishes an emission s pecification that any water separator equipped with a vapor recovery system shall reduce emissions such that the true partial pressure of the VOC in vent gases to the atmosphere will not exceed a level of 0.5 psia (3.4 kPa) in the HGB area. Section 115.132 requires that any water separator which separates materials containing VOC obtained from any equipment which is processing, refining, treating, storing, or handling VOC, unless each compartment be controlled in one of the following ways: 1) the compartmen t totally encloses the liquid contents and has all openings (such as roof seals and access doors) sealed; 2) the compartment is equipped with a floating roof or internal floating cover which will rest on the surface of the contents and must be equipped wit h a closure seal or seals to close the space between the roof edge and tank wall; 3) the compartment is equipped with a vapor recovery system which satisfies the established emission specifications; and 4) once any water separator becomes subject to these emission specifications it will always be subject to them (the once in always in will apply even if the throughput or emissions later fall below the exemption limits). Establishing these requirements will assist in lowering the VOC levels for this sector i n the HGB

area. Section 115.133 provides for an alternate methods control condition upon demonstrating and documenting continuous compliance with the applicable control requirements or exemption criteria as the case might be. This provision provides for op erational flexibility to a source. Section 115.135 set forth what test methods are to be used to determine compliance with emission specification or prescribed VOC control level. Among these tests are EPA Test Methods 1

- 4 for determining the flow rate, Tes t methods 18, 25, 25A, and 25 B for determining concentrations. Also for determination of true vapor pressure at actual storage temperature this section requires using American Society for Testing Materials (ASTM) Test Methods D323, D2879, D4953, D5190, or D5191; using API Publication 2517, Third Edition, 1989 or standard reference texts to convert from Reid vapor pressure to true vapor pressure, where applicable are required. Use of approved test methods will facilitate compliance determination. Section 11 5.136 sets forth what parameters are to be monitored and what records are to be maintained. Among such records are: the exhaust gas temperature immediately downstream of any direct

- flame incinerator; the gas temperature immediately upstream and downstream of any catalytic incinerator or chiller; and the VOC concentration of any carbon adsorption system exhaust gas to determine if breakthrough has occurred. Affected owner or operator shall install32 and maintain monitors to continuously measure and record oper ational parameters of any emission control device installed to meet applicable control requirements. Such records must be sufficient to demonstrate proper functioning of those devices to design specifications. All records shall be maintained for two years and be made available for review upon request. Monitoring and keeping of these record will assist in compliance determination of the affected source in the HGB area. Section 115.137 states what source may be exempt from these requirements. Among exempted units are water separator used exclusively in conjunction with the production of crude oil or condensate is exempt from 115.132(a) of this title (relating to Control Requirements) if the emissions from the separator have a combined weight of VOC equal to o r less than 100 pounds (45.4 kg) in any continuous 24

- hour period. To ensure this provision is not abused this section states that “it is unacceptable to disconnect any of the multiple sources routed through a common vent for purposes of complying with thi s exemption.” Section 115.139 establishes what counties are subject to these requirements and states that owner or operator of each VOC water separator shall continue to comply with the applicable VOC requirements of wastewater separators in the HGB area. For compliance date see 115.930. Sections 115.311

- 319 combined with sections 115.131

- 139 will provide for lowering of VOC emissions from this sector. We have previously stated that VOC and NOx RACT requirements under the Act are in place for the HGB area for the 1

15 Gasoline Service Stations Design Criteria for Stage I Vapor Control Systems

- Gasoline Service Stations, November 1975 §115.221

– 229

Section 115.221 sets forth emission specifications by stating that no person shall transfer, or allow the transfer of, gasoline from any tank

- truck tank into a stationary storage container which is located at a motor vehicle fuel dispensing facility, unles s the displaced vapors from the gasoline storage container are controlled of a vapor control system which reduces the emissions of VOC to the atmosphere to not more than 0.8 pound per 1,000 gallons (93 mg/liter) of gasoline transferred; or a vapor balance system which is operated and maintained in accordance wi th the provisions of 115.222. Section 115.222 states that vapor balance system will be assumed to comply with the specified emission limitation of if: the container is equipped with a submerged fill pipe and the path through the submerged fill pipe to the bottom of the tank must not be obstructed by a screen, grate, or similar device whose presence would preclude the determination of the submerged fill pipe's proximity to the tank bottom while the sub merged fill tube is properly installed; a vapor

tight return line is connected before gasoline can be transferred into the storage container; the vapor return line's cross

- sectional area is at least one

- half of the product drop line's cross

sectional area; and no avoidable gasoline leaks, as detected by sight, sound, or smell, exist anywhere in the liquid transfer or vapor balance systems. In addition, the only atmospheric emission during gasoline transfer into the storage container is through a storage con tainer vent line equipped with a pressure

- vacuum relief valve set to open at a pressure of no more than eight ounces per square inch (3.4 kPa). Section 115.223 provides for an alternate methods control condition while vapor recovery system is capable of me eting the applicable performance requirements for Motor Vehicle Fuel Dispensing Facilities, as certified by third

- party evaluation conducted by a qualified independent testing organization using a code or standard of practice and has been developed by a na tionally recognized agency, association, or independent testing laboratory. This provision provides for operational flexibility to a source.42 Section 115.224 establishes inspection requirements so that inspections for liquid leaks, visible vapors, or signif icant odors resulting from gasoline transfer shall be conducted at motor vehicle fuel dispensing facilities. Gasoline transfer shall be discontinued immediately when a leak is observed and shall not be resumed until the observed leak is repaired; and the g asoline tank

- truck tank must have been inspected for leaks within one year as evidenced by a prominently displayed certification affixed near the United States Department of Transportation certification plate. The inspection requirement will assist with co mpliance determination of the source in the HGB area. Section 115.225 set forth the testing methods an affected source in the HGB area will need to conduct. The test methods are EPA Test Methods 1

- 4 for determining flow rate, and Test Methods 18, 25, 25A, 25 B for determining VOC concentration, and Test Method 21for determining volatile organic compound leaks. Adoption of approved Test methods will make the control requirements federally enforceable. Section 115.226 sets forth the type of records an affecte d source in the HGB area should maintain and make them available for review or inspection upon request. Some of these records include: dates on which gasoline was delivered to the dispensing facility and the identification number and date of the last leak testing; a record of the results of any testing conducted at the motor vehicle fuel dispensing facility. The records must contain the calendar month and year, and the total facility gasoline throughput for each calendar month. Maintaining records and keepi ng them on site for two years will assist with compliance determination of the affected site. Section 115.227 states that the motor vehicle fuel dispensing facility which has dispensed no more than 10,000 gallons of gasoline in any calendar month after J anuary 1, 1991, and for which construction began prior to November 15, 1992, are exempt from the requirements this sector. This section will assist the field personnel with the rule applicability determination. Section 115.229 states that owner or operator of each motor vehicle fuel dispensing facility in the HGB area are required to comply with the applicable recordkeeping, monitoring, testing, and emission specifications requirements of this sector. For compliance date see 115.930. Sections 115.221

Section 115.112 estab lishes the control requirements based on the true vapor pressure and tank capacity of the storage tank when VOCs Other than Crude Oil and Condensate are stored. See Table 1(a) of this section. Also establishes the control requirements based on the true va por pressure and tank capacity of the storage tank when crude oil and condensate are stored in a tank. See Table II(a) of this section. This section also states that when a vapor control systems is used as a control device on any storage tank must maintai n a minimum control efficiency of 90%. If a flare is used, it must be designed and operated in accordance with 40 Code of Federal Regulations §60.18(b)

- (f) (as amended through December 22, 2008 (73 FR 78209)) and be lit at all times when VOC vapors are r outed to the flare. Section 115.113 provides for an alternate methods control condition upon demonstrating and documenting continuous compliance with the applicable control requirements or exemption criteria as the case might be. This provision provides fo r operational flexibility to a source. Section 115.114 establishes what the inspection requirements for each affected tank are. This provision should facilitate compliance determination. Section 115.115 set forth the parameters an affected source in the HGB area will need to monitor. For example, for a direct

- flame incinerator, the owner or operator shall continuously monitor the exhaust gas temperature immediately downstream of the device; for a condensation system, the owner or operator shall continuous ly monitor the outlet gas temperature to ensure the temperature is below the manufacturer's recommended operating temperature for controlling the volatile organic compounds (VOC) vapors routed to the device; and for a carbon adsorption system or carbon ads orber the owner or operator shall continuously monitor the exhaust gas44 VOC concentration of a carbon adsorption system that regenerates the carbon bed directly to determine breakthrough (using EPA Test Method 21). These monitoring requirements will facilit ate compliance determination. Section 115.116 establishes the testing requirements for an affected facility in the HGB area. For example; for a vapor control system, other than a vapor recovery unit or a flare, an initial control efficiency test must be co nducted in accordance with the approved test methods; and when A flare used to comply with the control requirements it must meet the design verification test requirements in 40 CFR §60.18(f) (as amended through December 22, 2008 (73 FR 78209)). In additio n, if the vapor control system is modified in any way that could decrease the control efficiency of the system, then the device must be retested within 60 days of the modification. Section 115.117 set forth what test methods are to be used to determine com pliance with emission specification or prescribed VOC control level. Among these tests are EPA Test Methods 1

- 4 for determining the flow rate, Test methods 18, 21, 22, 25, 25A, and 25 B. In addition, true vapor pressure must be determined using standard re ference texts or American Society for Testing and Materials Test Method D323, D2879, D4953, D5190, or D5191 for the measurement of Reid vapor pressure, adjusted for actual storage temperature in accordance with American Petroleum Institute Publication 2517 . Use of approved test methods will facilitate compliance determination. Section 115.118 establishes specific equations to determine reportable emissions, and states that all records must be maintained for two years and be made available for review upon r equest by authorized representatives (including any local air pollution control agency with jurisdiction). Section 115.119 establishes the date by which an affected source in the HGB area is to meet the applicable recordkeeping, monitoring, testing, and em ission specifications requirements of this sector. The compliance schedule will make this particular provision of Chapter 115 federally enforceable. Sections 115.112

- 119 will provide for lowering of VOC emissions from this sector. We have previously state d that VOC and NOx RACT requirements under the Act are in place for the HGB area for the 1

VOC : RACT for major VOC sources that do not fall into one of the above sector categories identified in Table C of this TSD , and are located in the HG B area is discussed here. The major source definition for the HGB area , classified as severe , is 25 TPY when uncontrolled. See section 182(e) of the Act. For the list of major VOC sources in the HGB area we are using the Appendix D of the April 6, 2010 Submitta l. A s stated else where in this document, TCEQ reviewed the point source emissions inventory and Title V databases to identify all major sources of NO X or VOC emissions. All sources in the Title V database that were listed as a major source for NO X or VOC emissions and included in the RACT analysis. For illustration purposes a sample company from the Appendix D list is shown below.

NOx : Using a similar a pproach , RACT for major NOx sources that are located in the HGB area is discussed here. The major source definition for the HGB area, classified as severe, is 25 TPY when uncontrolled. See section 182(e) of the Act. For the list of major NOx sources in the HGB

We ha ve reviewed TCEQ’s approach and RACT determination, and agree with their approach to include these sources in the inventory of the sources, and their RACT determination. Therefore, we are proposing that the requirements established in Chapter 117 for majo r sources in the HGB Area represent RACT under the 8

- Hour ozone NAAQS. Therefore, by implementing the 30 TAC Chapter 11 7 control requirements Texas has the 8

- Hour RACT in place for major NOx sources in the HGB area. We recommend propos ing their approval into Texas SIP. Conclusion for Component # 2 : The EPA had previously approved RACT for VOC and NOx into Texas’ SIP under the 1

- Hour ozone standard , thus finding that these control measures result in the lowest emissions limitation that a pa rticular source is capable of meeting through application of control technology that is reasonably available, considering technological and economic feasibility . Based on EPA’s May 18, 2006 RACT Q and A document, the framework identified above, and TCEQ’s certification , a permissible approach per 70 FR 71612, November 29, 2008 (Final Rule to Implement the 8

- Hour Ozone NAAQS), of its RACT w e are proposing to approve the 30 TAC Chapter 115 control requirements as meeting RACT for VOC sources ( both the CTG so urces identified in Table C and all major Non
