Notice of Proposed Rule
DAR File No.: 34349
Filed: 01/06/2011 06:33:12 AM
Purpose of the rule or reason for the change:
Rule R307-328 establishes the Stage I Vapor Recovery requirements for the State of Utah. Stage I gasoline vapor recovery systems are designed to capture the vapors expelled from an underground storage tank (UST) at a gas station when it is being filled. In this process, as gasoline is dispensed into the UST, excess vapors from the UST are transferred back into the tank truck and returned to the tank farm or loading facility where they are reprocessed or burned. Section R307-328-6 requires delivery trucks that service gas stations throughout Utah to be vapor tight and equipped to recover vapors and return them to the loading facilities. The delivery trucks are required to be tested annually between December 1st and May 1st to ensure that they are vapor tight. In 2009, the Utah Petroleum Marketers and Retailers Association requested a rule change to eliminate the December 1st - May 1st testing window and allow testing year round. Trucking companies were finding it difficult to complete the testing on all of their trucks during the five-month window. In addition, winter is the most difficult time to test and repair trucks because of poor weather conditions. Utah Division of Air Quality (UDAQ) staff reviewed the proposal and determined that there were other reasons to eliminate the five-month testing window. 1) The Maximum Achievable Control Technology (MACT) rule for Gasoline Distribution Facilities (Bulk Gasoline Terminals and Pipeline Breakout Stations), 40 CFR Part 63 Subpart R, requires an annual vapor tightness test for most of the delivery trucks that are subject to Rule R307-328. The MACT does not establish a testing window. It would be more efficient to align with the MACT testing schedule, allowing the owners and operators of these trucks to test trucks when they were scheduled for other maintenance, rather than waiting until the five-month testing window. 2) The five-month testing window causes difficulties for out-of-state trucks that are certified under the MACT, but are not allowed to refuel at Utah refineries because they were not tested within the five-month window. 3) The five-month testing window might be counterproductive in some cases because trucks are not tested in the middle of the summer and leaking trucks may not be identified until the following winter. 4) VOC emissions from tanker trucks may be important outside of the traditional ozone season of May - September. EPA has proposed expanding the ozone season in Utah to include the months of April and October, and elevated ozone values have been monitored during the middle of winter in the Uintah Basin. Technical work in support of the PM2.5 SIP has also identified VOC as an important precursor for PM2.5 during winter temperature inversions.
Summary of the rule or change:
The proposed amendments include the following changes: eliminate the five-month testing window, and instead reference the MACT requirements for an annual test; replace the current leak tightness standard (pressure change of three inches H2O over five minutes) with the more stringent MACT standard (pressure change of one inch H2O over five minutes); and remove the reference to the vapor testing procedures in Rule R307-342 and instead rely on the MACT standard that uses federal Method 27. (DAR NOTE: the proposed repeal of Rule R307-342 is under DAR No. 34348 in this issue, February 1, 2011, of the Bulletin.)
State statutory or constitutional authorization for this rule:
- Section 19-2-101
- Subsection 19-2-104(1)(a)
This rule or change incorporates by reference the following material:
- Adds 40 CFR Subpart 63.425(e), published by Government Printing Office, July 1, 2009
- Adds 40 CFR Subpart 63.421, published by Government Printing Office, July 1, 2009
Anticipated cost or savings to:
the state budget:
A possible time savings may be incurred due to the removal of duplicative requirements. No other cost or savings is anticipated for the state budget as this amendment does not create any new requirements.
No cost or savings is anticipated for local government as this amendment does not create any new requirements.
A possible savings may be incurred by small businesses due to the allowance of testing of gasoline cargo tanks over a longer period of time rather that all at once, and a possible time savings due to the removal of duplicative requirements. A possible cost may be incurred if gasoline cargo tanks do not currently meet the more stringent MACT standard.
persons other than small businesses, businesses, or local governmental entities:
A possible savings may be incurred by persons other than small businesses, businesses, or local government entities due to the allowance of testing of gasoline cargo tanks over a longer period of time rather that all at once, and a possible time savings due to the removal of duplicative requirements. A possible cost may be incurred if gasoline cargo tanks do not currently meet the more stringent MACT standard.
Compliance costs for affected persons:
A possible cost may be incurred if gasoline cargo tanks do not currently meet the more stringent MACT standard.
Comments by the department head on the fiscal impact the rule may have on businesses:
A possible savings may be incurred by affected persons due to the allowance of testing of gasoline cargo tanks over a longer period of time rather that all at once, and a possible time savings due to the removal of duplicative requirements. A possible cost may be incurred if gasoline cargo tanks do not currently meet the more stringent MACT standard.

R307-328. Gasoline Transfer and Storage.
The purpose of R307-328 is to establish
Reasonably Available Control Technology (RACT) for control of
gasoline vapors during the filling of [
gasoline transport vehicles] and storage tanks in Utah. The rule is
based on federal control technique guidance documents. This
requirement is commonly referred to as stage I vapor recovery.
Transport Vehicles]. R307-328 applies to the owner or
operator of any [ gasoline tank truck, railroad tank car, or other gasoline
transport vehicle] that loads or unloads gasoline in
(2) Gasoline Dispensing. R307-328 applies to the owner or operator of any bulk terminal, bulk plant, stationary storage container, or service station located in Utah that dispenses 10,000 gallons or more in any one calendar month.
(3) This rule applies to all [
transport vehicles] and
dispensing facilities that operate within Utah
according to the compliance schedule defined in section 328-9 of
The following additional definitions apply to R307-328.
"Bottom Filling" means the filling of a tank through an inlet at or near the bottom of the tank designed to have the opening covered by the liquid after the pipe normally used to withdraw liquid can no longer withdraw any liquid.
"Qualified contractor" means a contractor who has
been qualified by the executive secretary in accordance with
R307-342 to perform vapor tightness tests on gasoline transport
] "Submerged Fill Pipe" means any fill pipe with a discharge opening which is entirely submerged when the liquid level is 6 inches above the bottom of the tank and the pipe normally used to withdraw liquid from the tank can no longer withdraw any liquid.
R307-328-4. Loading of Tank Trucks, Trailers, Railroad Tank Cars, and Other Transport Vehicles.
(1) No person shall load or permit the
loading of gasoline into any
tank truck, trailer, railroad tank car, or other transport
vehicle] unless the emissions from such vehicle are
controlled by use of a vapor collection and control system and
submerged or bottom filling. RACT shall be required and in no case
shall vapor emissions to the atmosphere exceed 0.640 pounds per
1,000 gallons transferred.
(2) Such vapor collection and control system shall be properly installed and maintained.
(3) The loading device shall not leak.
(4) The loading device shall utilize the dry-break loading design couplings and shall be maintained and operated to allow no more than an average of 15 cc drainage per disconnect for 5 consecutive disconnects.
(5) All loading and vapor lines shall be equipped with fittings which make a vapor tight connection and shall automatically close upon disconnection to prevent release of the organic material.
(6) A gasoline storage and transfer installation that receives inbound loads and dispatches outbound loads ("bulk plant") need not comply with R307-328-4 if it does not have a daily average throughput of more than 3,900 gallons (15,000 or more liters) of gasoline based upon a 30-day rolling average. Such installations shall on-load and off-load gasoline by use of bottom or submerged filling or alternate equivalent methods. The emission limitation is based on operating procedures and equipment specifications using Reasonably Available Control Technology as defined in EPA documents EPA 450/2-77-026 October 1977, "Control of Hydrocarbons from Tank Truck Gasoline Loading Terminals," and EPA-450/2-77-035 December 1977, "Control of Volatile Organic Emissions from Bulk Gasoline Plants."

around the perimeter of a potential leak source as detected by a
combustible gas detector. Potential leak sources include, but are
not limited to, piping, seals, hoses, connections, pressure or
vacuum vents, and vapor hoods. In addition, no visible liquid leaks
are permitted during testing or monitoring.

R307-328-8. Alternate Methods of Control.
(1) Any person may apply to the executive secretary for approval of an alternate test method, an alternate method of control, an alternate compliance period, an alternate emission limit, or an alternate monitoring schedule. The application must include a demonstration that the proposed alternate produces an equal or greater air quality benefit than that required by R307-328, or that the alternate test method is equivalent to that required by these rules. The executive secretary shall obtain concurrence from EPA when approving an alternate test method, an alternate method of control, an alternate compliance period, an alternate emission limit, or an alternate monitoring schedule.
(2) Manufacturer's operational specifications, records, and testings of any control system shall use the applicable EPA Reference Methods of 40 CFR Part 60, the most recent EPA test methods, or EPA-approved state methods, to determine the efficiency of the control device. In addition, the owner or operator must meet the applicable requirements of record keeping for any control device. A record of all tests, monitoring, and inspections required by R307-328 shall be maintained by the owner or operator for a minimum of 2 years and shall be made available to the executive secretary or the executive secretary's representative upon request. Any malfunctioning control device shall be repaired within 15 calendar days after it is found by the owner or operator to be malfunctioning, unless otherwise approved by the executive secretary.
(3) For purposes of determining compliance with emission limits, volatile organic compounds and nitrogen oxides will be measured by the test methods identified in federal regulation or approved by the executive secretary. Where such a method also inadvertently measures compounds with negligible photochemical reactivity, an owner or operator may exclude these negligibly reactive compounds when determining compliance with an emissions standard.
R307-328-9. Compliance Schedule.
(1) Effective May 1, 2000, all Facilities located in Davis, Salt Lake, Utah, and Weber Counties shall be in compliance with this rule.
(2) All other facilities located in Utah, shall be in compliance with this rule according to the following phase-in schedule:
(a) Facilities located in Box Elder, Cache, Tooele and Washington Counties shall be in compliance with this rule by April 30, 2009.
