Current through December 26, 2024

Section 250-RICR-120-05-11.5 - Bulk Gasoline Terminals

A. § 11.5 of this Part shall apply to bulk gasoline terminals and appurtenant equipment necessary to load and unload the tank trucks, railroad tank cars or trailer compartment. If a source is ever considered a bulk terminal because it surpasses the daily throughput under the definition in § 11.3(A)(4) of this Part, it is always subject to this regulation even if it goes below the daily throughput.

11.5.1Prohibitions

A. No person shall load or unload gasoline into any tank trucks, railroad tank cars, or trailers from any bulk gasoline terminal unless the above-mentioned vessels are equipped with a vapor balance system, and

1. The bulk gasoline terminal is equipped with a vapor control system properly installed, maintained and in good working order, in operation and that prevents emissions to the atmosphere from exceeding 0.30 grams per gallon (80 grams/1000 liters) of gasoline loaded over any 6-hour period as determined by § 11.5.3 of this Part. The vapor collection and processing equipment must be designed and operated to prevent gauge pressure in the tank truck from exceeding eighteen (18) inches of water and prevent vacuum from exceeding six (6) inches of water, and

2. A connecting pipe or hose from the loading rack to the delivery vessel is equipped with fittings which are vapor tight and will automatically and immediately close upon disconnection so as to prevent release of volatile organic materials to the best extent possible, and

3. A vapor space connection on the tank truck, railroad tank car, or trailer equipped with fittings which are vapor tight and will automatically and immediately close upon disconnection so as to prevent release of volatile organic materials to the best extent possible.

4. The bulk gasoline terminal is equipped with a vapor control system, capable of complying with § 11.5.1(A)(1) of this Part, properly installed, in good working order, in operation and consistent with one of the following:

a. An adsorber or condensation system which processes and recovers at least ninety percent (90%) by weight of all vapors and gases from the equipment being controlled; or,

b. A vapor collection system which directs all vapors to a fuel gas system and reduces emissions by at least ninety percent (90%) by weight all vapors and gases from the devices being controlled; or,

c. A control system determined to be equally effective and approved by the Director.

B. Sources affected under § 11.5 of this Part may not:

1. Allow gasoline to be discarded in sewers or stored in open containers or handled in any manner that would result in evaporation, nor

2. Allow the pressure in the vapor collection system to exceed the tank truck or trailer pressure relief settings.

C. All pumps and compressors handling gasoline shall have mechanical seals or other equipment for the purposes of air pollution control as approved by the Director and EPA. The seals or other equipment, when tested by a combustible gas detector at 2.5 centimeters from any potential leak points, shall give no reading of greater than one hundred percent (100%) of the lower explosive limit, measured as propane.

D. The emergency venting of vessels covered by § 11.5.1(A) of this Part shall be in accordance with the federal DOT specifications for cargo tanks and tank cars authorized to carry hazardous materials. Emergency venting shall not be considered a violation.

11.5.2Records

A. Records shall be maintained at the facility by the owner or operator of a bulk gasoline terminal and shall include:

1. Records of daily throughput quantities of gasoline.

2. Records for both scheduled and unscheduled maintenance of the vapor control system that is described in § 11.5.1(A)(1) of this Part.

B. Records cited in § 11.5.2(A) of this Part should be maintained for a period of three (3) years and should be accessible for review by the Director, personnel designated by the Director, or the EPA.

11.5.3Compliance Test Methods

A. Compliance with the emission limitations set forth in § 11.5 of this Part shall be determined by using the procedures, compliance averaging times (six (6) hours), and test methods which are detailed in 40 C.F.R § 60.503, incorporated in § 11.2(D) of this Part, or any other method approved by the Director and EPA.
