PROPOSED RULES
POLLUTION CONTROL AGENCY
Original Notice.
Exempt from preproposal statement of inquiry under RCW 70.94.141(1).
Title of Rule: Amend: Regulation II, Sections 1.05, 2.04, 2.05, 2.07, 2.08.
Repeal: Regulation II, Section 2.06.
Adopt: Regulation II, Section 2.01.
Purpose: The proposed amendments are designed largely to ensure the integrity of the gasoline vapor recovery program. This would be accomplished through periodic inspection and testing of vapor recovery equipment at gas stations, enhancements to the periodic testing requirements for transport tanks, and by requiring that gasoline vapors collected from gas stations are returned to a facility that is capable of recovering (or combusting) them.
A number of changes are being proposed to clarify and simplify the regulations, including but not limited to the addition of a definitions section specific to the gasoline marketing regulations, merging of the sections for terminals and bulk plants, and segregating the requirements for bulk gasoline distribution facilities from those for transport tanks. The requirements for large volatile organic compound storage tanks would be moved to a different article and revised slightly to reflect that they are sometimes used for products other than petroleum.
Other Identifying Information: Section 1.05 - Special Definitions; 2.01 - Definitions; 2.04 - Volatile Organic Compound Storage Tanks; 2.05 - Bulk Gasoline Distribution Facilities; 2.06 - Bulk Gasoline Plants; 2.07 - Gasoline Stations; 2.08 Gasoline Transport Tanks.
Statutory Authority for Adoption: Chapter 70.94 RCW.
Statute Being Implemented: RCW 70.94.141.
Summary: Section 2.01, Definitions. This section would be added for definitions related to gasoline marketing. Pertinent definitions from Section 1.05 moved here and some would be revised.
Section 2.05, Bulk Gasoline Distribution Facilities. The requirements for bulk gasoline plants (Section 2.06) and gasoline loading terminals (2.05) would be merged into this section, which would apply to all facilities that supply gasoline to other facilities equipped with vapor recovery systems. Requirements related to gasoline loading equipment would be moved from Section 2.08 to this section and the emission standard would be tightened to 10 milligrams per liter of gasoline transferred. Technical specifications for continuous emission monitoring systems on vapor recovery systems using carbon adsorption would be added.
Section 2.07, Gasoline Stations. Stage 2 vapor recovery equipment would have to be inspected weekly and tested annually. Stage 1 vapor recovery equipment would have to be inspected after each bulk delivery to the station. Repairs to defective stage 1 and 2 equipment would have to be implemented within specified time frames.
Section 2.08, Gasoline Transport Tanks. Testing requirements for transport tanks would be tightened and test certificates would have to include more information.
Section 3.04, VOC Storage Tanks. The requirements for volatile organic compound storage tanks would be moved from Section 2.04 to this section, since they apply to products other than petroleum. The emission standard for control equipment would be changed to a more general form (i.e., 95% control).
Reasons Supporting Proposal: Field testing has found that stage 2 vapor recovery equipment at gas stations is only achieving about 79% of the expected emission reduction. Testing of this equipment in accordance with its certification requirements is expected to reduce emissions by over 500 tons per year. Testing has been shown to be cost effective in California, reducing emissions for about $750 per ton (about $400 per station annually).
Similarly, field testing of gasoline transport tanks has found that vapor emissions during transport can be significantly reduced by testing the vapor valves on the transport tank and reducing the allowable leak rate from the storage compartments. The requirements have been imposed on all transport tanks loading at refineries and are based upon the requirements adopted in California.
Transport tanks delivering to storage tanks at gas stations and bulk gasoline plants equipped with a vapor recovery system have been required to recover the vapors from the stationary storage tank. The proposal would require the vapors to be delivered to a bulk gasoline distribution facility with vapor recovery equipment. The larger bulk gasoline distribution facilities are presently equipped with vapor recovery equipment. Smaller bulk gasoline distribution facilities would service their few accounts with vapor recovery directly from the larger bulk gasoline distribution facilities. No capital expenditures would be required, making this proposal reasonably cost effective.

Name of Proponent: Puget Sound Air Pollution Control Agency, governmental.
Agency Comments or Recommendations, if any, as to Statutory Language, Implementation, Enforcement, and Fiscal Matters: The state implementation plan will be updated to reflect these amendments.
Rule is not necessitated by federal law, federal or state court decision.
Explanation of Rule, its Purpose, and Anticipated Effects: Gasoline is a volatile commodity. In the Puget Sound region, over 1.3 billion gallons are consumed annually. The gasoline vapors are composed of hydrocarbons which are not only toxic but react with sunlight to produce photochemical smog (ozone). Gasoline vapor recovery is one of the principal control strategies to control smog formation.
Stage 2 vapor recovery takes vapors displaced during the filling of motor vehicle fuel tanks and returns them to the underground storage tank at the gas station. Stage 1 vapor recovery equipment takes these vapors and the vapors displaced during the filling of the underground storage tank and returns them to the transport tank. Bulk gasoline distribution facilities take these vapors when they fill the transport tank and either convert them back to a liquid product for sale or combust them. In this manner, tens of thousands of tons of emissions are prevented and public health is protected.
The proposed amendments would significantly improve the vapor recovery program and prevent the release of between 500 and 1,000 tons per year of gasoline vapors.
Proposal Changes the Following Existing Rules: Section 2.01, Definitions. This section would be added for definitions related to gasoline marketing. Pertinent definitions from Section 1.05 moved here and some would be revised.
Section 2.05, Bulk Gasoline Distribution Facilities. The requirements for bulk gasoline plants (Section 2.06) and gasoline loading terminals (2.05) would be merged into this section, which would apply to all facilities that supply gasoline to other facilities equipped with vapor recovery systems. Requirements related to gasoline loading equipment would be moved from Section 2.08 to this section and the emission standard would be tightened to 10 milligrams per liter of gasoline transferred. Technical specifications for continuous emission monitoring systems on vapor recovery systems using carbon adsorption would be added.
Section 2.07, Gasoline Stations. Stage 2 vapor recovery equipment would have to be inspected weekly and tested annually. Stage 1 vapor recovery equipment would have to be inspected after each bulk delivery to the station. Repairs to defective stage 1 and 2 equipment would have to be implemented within specified time frames.
Section 2.08, Gasoline Transport Tanks. Testing requirements for transport tanks would be tightened and test certificates would have to include more information.
Section 3.04, VOC Storage Tanks. The requirements for volatile organic compound storage tanks would be moved from Section 2.04 to this section, since they apply to products other than petroleum. The emission standard for control equipment would be changed to a more general form (i.e., 95% control).

However, notification of the test date shall be submitted to the Agency at least 5 days in advance of the test and copies of all test results shall be kept on site for at least 2 years from the date of the test.
AMENDATORY SECTION
REGULATION II SECTION 2.08 ((LEAKS FROM)) GASOLINE TRANSPORT TANKS
((AND VAPOR RECOVERY SYSTEMS))
(((a) Section 2.08 shall apply to all gasoline transport tanks and all facilities subject to
Sections 2.05, 2.06, and 2.07 of Regulation II.
(b) It shall be unlawful for any person to cause or allow the transfer of gasoline between a facility subject to the requirements of Section 2.08 and a gasoline transport tank unless a current leak test certification for the transport tank is on file with the facility or a valid inspection sticker is displayed on the vehicle.
(c) It shall be unlawful for any person to cause or allow the use of any transport tank for the transfer of gasoline at a facility subject to the requirements of Section 2.08, unless the tank:
(1) Is leak tested annually;
(2) Displays a sticker and carries a certificate that:
(A) Shows the date the tank last passed the leak test; and
(B) Shows the identification number of the tank; and
(3) Is loaded and unloaded in such a manner that the concentration of gasoline vapors is below the lower explosive limit (expressed as propane) at all points a distance of 2.5 cm (1 inch) or greater from any potential leak source. Any transport tank that fails to meet the requirements of this paragraph shall be repaired and retested in accordance with the provisions of Section 2.08(e) within 10 days. The Control Officer shall be notified in writing within 5 days after the completion of the required leak test.
(d) It shall be unlawful for any person to cause or allow the operation of any facility subject to Section 2.08 unless the vapor recovery system and the gasoline loading equipment is operated during all loading and unloading of gasoline such that:
(1) The concentration of gasoline vapors is below the lower explosive limit (expressed as propane) at all points a distance of 2.5 cm (1 inch) or greater from any potential leak source; and
(2) There are no liquid leaks in excess of 3 drops per minute and there is no more than 10 ml of liquid drainage per disconnect.
(e) During the test required by Section 2.08(c), each transport tank shall sustain a pressure change of no more than 0.75 kPa (3 inches) of water in 5 minutes when pressurized to a gauge pressure of 4.5 kPa (18 inches) of water and evacuated to a gauge pressure of 1.5 kPa (6 inches) of water during the test.))
(a) This section shall apply to all transport tanks that deliver gasoline to gasoline stations or bulk gasoline distribution facilities equipped with a vapor recovery system.
(b) It shall be unlawful for the owner or operator of a transport tank to cause or allow the transfer of gasoline at a facility equipped with a vapor recovery system unless:
(1) The transport tank is also equipped with a vapor recovery system;
(2) The transport tank is tested annually in accordance with the procedures in Method 27
of 40 CFR Part 60, Appendix A by pressurizing the tank to gauge pressures of 18 and - 6 inches
of water and waiting for a time period of 5 minutes during which the pressure change is no more
than:
| tank capacity (gallons) | pressure change (inches of water) |
| 2,500 or more | 1.0 |
| 1,500-2,499 | 1.5 |
| 1,000-1,499 | 2.0 |
| 999 or less | 2.5 |
(4) The transport tank carries a certificate that includes the following information:
(A) Testing company name, date, and test location;
(B) Tester's name, title, and signature;
(C) Transport tank owner's name and address;
(D) Transport tank identification number;
(E) Type of test: pressure decay, vacuum decay, or internal vapor valve;
(F) Vapor tightness repair (if any): nature of repair work and when performed in relation to the test; and
(G) Test results: pressure or vacuum change, time period of test.
(5) The transport tank displays a sticker near the Department of Transportation certification plate, which shows the identification number of the transport tank and the date the transport tank last passed the tests specified in this section; and
(6) The vapor recovery system is employed and the concentration of gasoline vapors is below the lower explosive limit (measured as propane) at all points a distance of 1 inch or greater from any potential leak source on the transport tank. (Any transport tank that fails to meet this requirement shall be repaired and retested for compliance with Sections 2.08 (b)(2) and (b)(3) of this regulation within 10 days, and a copy of the revised compliance certificate shall be sent to the Agency within 5 days after completing the required leak test.)
(c) Transport tanks tested prior to August 1, 1999 shall be subject to the requirements in Sections 2.08 (b)(2) and (b)(3) of this regulation at the time of their next annual test.
