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.

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.
