Tenn. Comp. R. & Regs. 1200-03-18-.22 - BULK GASOLINE PLANTS

(1) Applicability of this rule is as follows:

(a) This rule applies to all unloading, loading, and storage operations at bulk gasoline plants in Anderson, Blount, Carter, Cheatham, Davidson, Dickson, Fayette, Hamilton, Hawkins, Haywood, Jefferson, Knox, Loudon, Marion, Meigs, Montgomery, Putnam, Robertson, Rutherford, Sevier, Shelby, Sullivan, Sumner, Tipton, Unicoi, Union , Washington, Williamson, and Wilson Counties and to gasoline tank trucks delivering or receiving gasoline at these bulk gasoline plants.

(b) The following are subject only to the requirements of Parts (3)(c)7, 8, and 9 of this rule:

1. Any stationary storage tank of 2,082 liters (L) (550 gallons [gal]) capacity or less notwithstanding Rule .06 of this chapter; or

2. Any bulk gasoline plant with an average daily throughput of gasoline of less than 15,000 L (4,000 gal) on a monthly average provided that records are maintained according to the requirements in Subparagraph (5)(a) of this rule. Any plant that becomes or is currently subject to all of the provisions of this rule by exceeding this applicability threshold will remain subject to these provisions even if its throughput later falls below the applicability threshold.

(2)

(Reserved)

(3) Standards as follow apply:

(a) Each bulk gasoline plant subject to this rule shall be equipped with a vapor balance system between the gasoline storage vessel and the incoming gasoline tank truck designed to capture and transfer vapors displaced during filling of the gasoline storage vessel. These lines shall be equipped with fittings that are vapor tight and that automatically and immediately close upon disconnection.

(b) Each bulk gasoline plant subject to this rule shall be equipped with a vapor balance system between the gasoline storage vessel and the outgoing gasoline tank truck designed to capture and transfer vapors displaced during the loading of the gasoline tank truck. The vapor balance system shall be designed to prevent any vapors collected at one loading rack from passing to another loading rack.

(c) Each owner or operator of a bulk gasoline plant subject to this rule and owner or operator of each tank truck delivering or receiving gasoline at a plant subject to this rule, as applicable, shall act to ensure that the procedures described below are followed during all loading, unloading, and, with respect to the owner or operator of the plant, storage operations:

1. The vapor balance system shall be connected between the tank truck and storage vessel during all gasoline transfer operations;

2. All storage vessel openings, including inspection hatches and gauging and sampling devices shall be vapor tight when not in use;

3. The gasoline tank truck compartment hatch covers shall not be opened during the gasoline transfer;

4. All vapor balance systems shall be designed and operated at all times to prevent gauge pressure in the gasoline tank truck from exceeding 450 millimeters (mm) (18 inches [in]) of water and vacuum from exceeding 150 mm (5.9 in) of water during product transfers;

5. No pressure vacuum relief valve in the bulk gasoline plant vapor balance system shall begin to open at a system pressure of less than 450 mm (18 in) of water or at a vacuum of less than 150 mm (5.9 in) of water;

6. All product transfers involving gasoline tank trucks at bulk gasoline plants subject to this rule shall be limited to vapor-tight gasoline tank trucks;

7. Filling of storage vessels shall be restricted to submerged fill;

8. Loading of outgoing gasoline tank trucks shall be limited to submerged fill; and

9. Owners or operators of bulk gasoline plants or owners or operators of tank trucks shall observe all parts of the transfer and shall discontinue transfer if any leaks are observed.

(d) Each calendar month, the vapor balance systems and each loading rack handling gasoline shall be inspected for liquid or vapor leaks during gasoline transfer operations. For purposes of this subparagraph, detection methods incorporating sight, sound, or smell are acceptable. Each leak that is detected shall be repaired within 15 calendar days after it is detected. Dripping liquid resulting upon disconnect following gasoline transfer shall not constitute a leak.

(4) A pressure measurement device (liquid manometer, magnehelic gauge, or equivalent instrument) capable of measuring 500 mm (20 in) of water gauge pressure within a ± 2.5 mm (0.098 in) of water precision, shall be calibrated and installed on the bulk gasoline plant vapor balance system at a pressure tap, located as close as possible to the connection with the gasoline tank truck, to allow determination of compliance with Part (3)(c)4 of this rule.

(5) The owner or operator of a facility subject to this rule shall maintain the following records for at least 3 years and shall make these records available to the Technical Secretary upon request:

(a) Daily records showing the quantity of gasoline loaded into gasoline tank trucks; and

(b) A record of each monthly leak inspection kept on file at the plant. Inspection records shall include, as a minimum, the following information:

1. Date of inspection;

2. Findings (may indicate no leaks discovered or location, nature, and severity of each leak);

3. Leak determination method;

4. Corrective action (date each leak repaired; reasons for any repair interval in excess of 15 calendar days); and

5. Inspector name and signature.

(6) The owner or operator of any facility containing sources subject to this rule shall comply with the requirements in paragraphs .04(1) and (2) of this chapter, except that for any bulk gasoline plant in Anderson, Blount, Carter, Cheatham, Dickson, Fayette, Hamilton, Hawkins, Haywood, Jefferson, Knox, Loudon, Marion, Meigs, Montgomery, Putnam, Robertson, Sevier, Sullivan, Tipton, Unicoi, Union, or Washington County that is an existing source on December 29, 2004 the initial compliance certification required in paragraph .04(1) shall be submitted by May 1, 2006 instead of the date specified in this paragraph .04(1).
