Agency: Antelope Valley Air Quality Management District (AVAQMD)

SIP Approved Rule: Rule 461

– Gasoline Transfer and Dispensing Adopted

– September 8, 1995 Submitted

– January 31, 1996 EPA Approved

– October 7, 1996 (61 FR 52297)

Subject of this TSD: Rule 461

- Gasoline Transfer and Dispensing Amended

RULE SUMMARY

– AVAQMD Rule 461, Gasoline Transfer and Dispensing, is a rule designed to limit volatile organic compound (VOC) emissions during the transfer of gasoline from any tank truck, trailer, or railroad tank car into any stationary storage tank or mobile fueler , and from any stationary storage tank or mobile fueler into any mobile fueler or motor vehicle fuel tank. AVAQMD is a severe non

attainment area for the 8

- hour ozone national ambient air quality standard (NAAQS) (40 CFR 81.305), and AVAQMD revised Rule 46 1 partly to address the associated Clean Air Act (CAA) obligations.

The significant changes to Rule 461 relative to the SIP approved rule include:

1. Section B, a dded several definitions and made other editorial changes to improve clarity.

2. Section C, a dded new requirements for recordkeeping, training, equipment installation, maintenance, inspection and certification

.

3. Section D, a dded several performance and re

- verification test methods.

4. Section E, a dded new exemption for Phase II vapor recovery requiremen ts for non

- retail fleets where at least 95% of the fleet is equipped with onboard refueling vapor recovery ( ORVR )

.

EPA EVALUATION CRITERIA

- The following criteria were used to evaluate the submitted Rule 70:

1. Enforceability

– The Bluebook (Issues Relating to VOC Regulation Cutpoints, Deficiencies, and Deviations), EPA, May 25, 1988 and the Little Bluebook (Guidance Document for Correcting Common VOC & Other Rule Deficiencies), EPA Region 9, August 21, 2001, wer e used to help evaluate compliance with CAA §110(a)(2)(A) requirement for enforceability.

2. RACT

– EPA’s Control Technique Guidelines (CTG) titled, “Technical Guidance

- Stage II Vapor Recovery Systems for Control of Vehicle Refueling Emissions at Gasoline Dispensing Facilities” (EPA 450/3

- 91

- 022), “Control of Volatile Organic Emissions From Bulk Gasoline Plants”( EPA

450/2

- 77

- 035), “Control of Vola tile Organic Emissions From Storage of Petroleum Liquids in Fixed

- Roof Tanks”(EPA

- 450/2

- 77

- 036), “Control of Volatile Organic Emissions from PetroleumLiquid Storage in External Floating Roof Tanks”( EPA

- 450/2

- 78

- 047), “Stationary Sources” (EPA

453/R

- 92

- 01 8 (ACT)) , EPA’s Draft Model Rule,” Gasoline Dispensing Facility

– Stage II Vapor Recovery, (August 17, 1992), “ Gasoline Vapor Recovery Guidelines” , EPA Region IX (April 24, 2000) and other state and local rules for this category were used to help evaluate the RACT requirements of CAA §182(b)(2) and §182(f).

3. SIP Relaxation

– Where previous versions of rules have been SIP approved, new submittals must comply with CAA §110(l) and §193 regarding SIP relaxations.

EPA EVALUATION

- The submitted AVAQMD Rule 461 is more stringent than the approved SIP, largely because of added administrative and technical details, and does not relax the existing SIP

- approved rule. The current SIP submittal generally contains sufficient testing and recordkeeping requirements to sa tisfy enforcement requirements. The stringency of requirements in submitted Rule 461 is also generally consistent with relevant guidance and analogous rules in other areas that help define RACT.

RULE DEFICIENCIES

– We have identified no deficiencies with R ule 461 sufficient for EPA to propose less than full approval.

RECOMMENDATIONS

– The following revisions are not currently the basis for rule disapproval, but are recommended for the next time the rule is amended.

Section C (1) (c) should reference section B (32) for Vapor Tight.

EPA ACTION

– The submitted revisions to Rule 461 will help clarify the SIP and improve compliance

assurance. The rule largely fulfills the relevant CAA §110 and part D requirements. EPA staff recommends approval of Rule 461 pursuant to CAA §110(k)(3) and §301(a).
