b. the last internal inspection of the ship or barge listed on its Certificate of Inspection was prior to July 23, 1990;

c. the loading which results in the excess emissions occurs before May 1, 1994.

3. Any request for an extension of the compliance dates will be considered on a case-by-case basis in response to a written request to the administrative authority and in accordance with LAC 33:III.2119.

4. A facility that has become subject to this regulation as a result of a revision of the regulation shall comply with the requirements of this Section as soon as practicable, but in no event later than one year from the promulgation of the regulation revision.

E. Test Methods and Procedure

1. For the purpose of determining compliance with the mass emission limitations of LAC 33:III.2108.C.3 the following reference methods shall be used:

a. for the determination of volume at the exhaust vent:

i. Method 2B ( 40 CFR Part 60, Appendix A, as incorporated by reference at LAC 33:III.3003) for combustion vapor processing systems (except flare stacks);

ii. Method 2A ( 40 CFR Part 60, Appendix A, as incorporated by reference at LAC 33:III.3003) for all other vapor processing systems;

b. for the determination of total organic compounds concentration at the exhaust vent, Method 25A or 25B ( 40 CFR Part 60, Appendix A, as incorporated by reference at LAC 33:III.3003). The calibration gas shall be either propane or butane.

2. Vapor processing systems utilizing a flare stack to destruct the collected VOCs will be exempt from testing and must be designed and operated in accordance with 40 CFR 60.482 - 10(d), as incorporated by reference in LAC 33:III.Chapter 30.

3. Immediately prior to the performance test for determination of compliance, all potential sources of vapor leakage in the facility's vapor collection system equipment shall be monitored for leaks using Method 21 ( 40 CFR Part 60, Appendix A, as incorporated by reference at LAC 33:III.3003). The monitoring shall be conducted only while a ship or barge is being loaded and should cover all parts of the vapor system, including tank hatches, that operate at pressures above atmospheric pressure. All leaks shall be repaired prior to conducting the performance test.

4. The test procedure for determining compliance with LAC 33:III.2108.C.3 shall be that specified below.

a. All testing equipment shall be prepared and installed as specified in the appropriate test methods.

b. The time period for a performance test shall be not less than three hours. As much as possible, testing should be conducted during the three-hour period in which the highest emissions normally occur (near the end of the loading).

c. For intermittent vapor processing systems:

i. the vapor holder level shall be recorded at the start of the performance test. The end of the performance test shall coincide with a time when the vapor holder is at its original level;

ii. at least two start-ups and shutdowns of the vapor processor shall occur during the performance test. If this does not occur under automatically-controlled operation, the system shall be manually controlled.

d. The volume of crude oil, gasoline and volatile organic compounds loaded during the performance test period, whose vapor emissions are controlled by the processing system being tested, shall be determined.

e. An emission testing interval shall consist of each five-minute period during the performance test. For each interval:

i. the reading from each measurement instrument shall be recorded; and

ii. the volume exhausted and the average total organic compounds concentration in the exhaust vent shall be determined, as specified in the appropriate test method. The average total organic compounds concentration shall correspond to the volume measurement by taking into account the sampling system response time.

f. The mass emitted during each testing interval shall be calculated as follows.

where:

E = mass of total organic compounds emitted per volume of crude oil, gasoline and volatile organic compounds loaded, mg/liter

Mei = mass of total organic compounds emitted during testing interval i, mg

L = total volume of crude oil, gasoline and volatile organic compounds loaded, liters

n = number of testing intervals

5. The owner or operator may adjust the emission results to exclude the methane and ethane content in the exhaust vent by the chromatographic method shown in Method 25 ( 40 CFR Part 60, Appendix A, as incorporated by reference at LAC 33:III.3003).

6. At least 30 days prior to performing any emission test, notification of testing shall be made to the Office of Environmental Services to afford the department the opportunity to conduct a pretest conference and to have an observer present.

F. Reporting and Recordkeeping

1. The results of any testing done in accordance with Subsection E of this Section shall be reported to the Office of Environmental Services within 60 days of the test.

2. The following records shall be kept on file at the affected facility for at least two years and shall be made available for inspection by a representative of the administrative authority on request:

a. daily throughput of liquid by type;

b. daily record of the number of each type of vessel loaded and the type and quantity of each liquid loaded on each vessel;

c. records of all replacements or additions of components performed on the vapor processing system;

d. records on control equipment operating parameters such as monitoring for breakthrough on carbon adsorption devices, pump amperes, and temperatures in refrigeration systems;

e. if any loadings are conducted which result in emissions exceeding those listed in LAC 33:III.2108.C.3 a record of the name, owner, type and quantity of liquid loaded, the date of loading and the vessel's last internal examination dates listed on its Certificate of Inspection shall be maintained for three years.

G. Operation and Maintenance

1. No person may load gasoline, crude oil or other VOC's into ships or barges at affected facilities unless all loading and vapor lines, arms and hoses are equipped with fittings which make vapor-tight connections and provide tight shut-off when disconnected.

2. Provisions must be made to prevent spills or leaks during attachment or disconnection of filling lines, hoses or arms. Liquids subject to this rule shall not be spilled or handled in any other manner that would result in evaporation to the atmosphere.

3. All equipment associated with the loading of gasoline, crude oil or other VOC's into ships or barges at affected facilities shall be maintained to be leak-free, gas-tight and in good working order.

H. Safety/Emergency. Nothing in this rule shall be construed to:

1. require any act or omission that would be in violation of any regulation or other requirement of the United States Coast Guard; or

2. prevent any act or omission that is necessary to secure the safety of a vessel or for saving life at sea.
