RULE ANALYSIS

Purpose of the rule or reason for the change:

On 08/25/2015, the EPA proposed conditional approval of sections of Utah's PM2.5 State Implementation Plan (SIP). As a condition for approving the SIP, EPA is requiring the state to amend Section R307-328-4. The state sent a letter to the EPA on 08/04/2015, that committed to revising the SIP. This amendment will partially satisfy that commitment.

Summary of the rule or change:

The rule states that gasoline loading shall be performed by "submerged filling or alternative equivalent methods." DAQ is proposing to remove "alternative equivalent methods" because filling should be performed via submerged delivery to reduce VOC generation.

State statutory or constitutional authorization for this rule:

• Section 19-2-104

Anticipated cost or savings to:

the state budget:

There will be no costs or savings to the state budget because there is no equivalent method to "submerged filling." As a result, removing the phrase "equivalent method" will only have the impact of more clearly describing the appropriate method for gasoline loading.

local governments:

There will be no costs or savings for local government because there is no equivalent method to "submerged filling." As a result, removing the phrase "equivalent method" will only have the impact of more clearly describing the appropriate method for gasoline loading.

small businesses:

There will be no costs or savings for small businesses because there is no equivalent method to "submerged filling." As a result, removing the phrase "equivalent method" will only have the impact of more clearly describing the appropriate method for gasoline loading.

persons other than small businesses, businesses, or local governmental entities:

There will be no costs or savings for other persons because there is no equivalent method to "submerged filling." As a result, removing the phrase "equivalent method" will only have the impact of more clearly describing the appropriate method for gasoline loading.

Compliance costs for affected persons:

There will be no costs for affected persons because there is no equivalent method to "submerged filling." As a result, removing the phrase "equivalent method" will only have the impact of more clearly describing the appropriate method for gasoline loading.

Comments by the department head on the fiscal impact the rule may have on businesses:

There will be no fiscal impact on businesses because there is no equivalent method to "submerged filling." As a result, removing the phrase "equivalent method" will only have the impact of more clearly describing the appropriate method for gasoline loading.

R307. Environmental Quality, Air Quality.

R307-328. Gasoline Transfer and Storage.

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 gasoline cargo tank 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." The design effectiveness of such equipment and the operating procedures must be documented and submitted to and approved by the director.

(7) Hatches of gasoline cargo tanks shall not be opened at any time during loading operations except to avoid emergency situations or during emergency situations. Pressure relief valves on storage tanks and gasoline cargo tanks shall be set to release at the highest possible pressure, in accordance with State or local fire codes and National Fire Prevention Association guidelines. Pressure in the vapor collection system shall not exceed the gasoline cargo tank pressure relief setting.

(8) Each owner or operator of a gasoline storage or dispensing installation shall conduct testing of vapor collection systems used at such installation and shall maintain records of all tests for no less than two years. Testing procedures of vapor collection systems shall be approved by the director and shall be consistent with the procedures described in the EPA document, "Control of Volatile Organic Compound Leaks from Gasoline Tank Trucks and Vapor Collection Systems," EPA-450/2-78-051.

(9) Semi-annual testing shall be conducted and records maintained of such test. The frequency of tests may be altered by the director upon submittal of documentation which would justify a change.

(10) The vapor collection and vapor processing equipment shall be designed and operated to prevent gauge pressure in the gasoline cargo tank from exceeding 18 inches of water and prevent vacuum from exceeding 6 inches of water. During testing and monitoring, there shall be no reading greater than or equal to 100 percent of the lower explosive limit measured at 1.04 inches 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.
