Current through Register Vol. 50, No. 9, September 20, 2024
A.
Oil/Water-Separation. Single or multiple compartment volatile organic compound
water separators which receive effluent water from any equipment processing,
refining, treating, storing, or handling volatile organic compounds shall be
equipped with one of the following vapor loss control devices properly
installed, in good working order and in operation.
1. A container having all openings sealed and
totally enclosed liquid contents. All gauging and sampling devices will be
gas-tight except when gauging or sampling is taking place.
2. A container equipped with a floating roof,
consisting of a pontoon type, double deck type roof, or internal floating cover
which rests or floats on the surface of the contents and is equipped with a
closure seal or seals to close the space between the roof edge and container
wall. All gauging and sampling devices will be gas-tight except when gauging or
sampling is taking place.
3. A
container equipped with a vapor disposal system capable of processing such
organic vapors and gases so as to limit their emission to the atmosphere to the
same extent as LAC 33:III.2109.A.1 and 2 and with all container gauging and
sampling devices gas-tight except when gauging or sampling is taking
place.
4. Other equivalent
equipment or means as may be approved by the administrative
authority*.
B.
Exemptions from LAC 33:III.2109.A
1. Volatile
organic compound water separators used exclusively in conjunction with the
production of crude oil or condensate are exempt from the provisions of LAC
33:III.2109.A.
2. Any single or
multiple compartment volatile organic compound water separator which separates
less than 200 gallons (757 liters) a day of materials containing volatile
organic compounds.
3. Any single or
multiple compartment volatile organic compound water separator which separates
materials having a true vapor pressure of volatile organic compounds less than
0.5 psia (3.4 kPa).
4. Except for
the parishes of Ascension, Calcasieu, East Baton Rouge, Iberville, Livingston,
Pointe Coupee, and West Baton Rouge, any single- or multiple-compartment
volatile organic compound water separator emitting 100 tons per year or less of
regulated hydrocarbons (uncontrolled) is exempt from the provisions of LAC
33:III.2109.A.
5. Any facility may
choose to reduce the flow of volatile organic compounds to the oil-water
separator by process or equipment modifications at the source(s) as an
alternate to the requirements of LAC 33:III.2109.A. Such alternate means of
compliance must be shown to result in a reduction of VOC emissions at least as
great as would result from application of the measures specified in LAC
33:III.2109.A.
C.
Compliance. Compliance with LAC 33:III.2109.A shall be determined by monthly
visual inspections or by use of one of the following test methods where
appropriate:
1. Test Method 1-4 (40 CFR Part
60, Appendix A, as incorporated by reference at LAC 33:III.3003) for
determining flow rates, as necessary;
2. Test Method 18 ( 40 CFR Part 60, Appendix
A, as incorporated by reference at LAC 33:III.3003) for measuring gaseous
organic compound emissions by gas chromatographic analysis;
3. Test Method 21 ( 40 CFR Part 60, Appendix
A, as incorporated by reference at LAC 33:III.3003) for determination of
volatile organic compound leaks;
4.
Test Method 25 ( 40 CFR Part 60, Appendix A, as incorporated by reference at
LAC 33:III.3003) for determining total gaseous nonmethane organic emissions as
carbon;
5. determination of true
vapor pressure using ASTM Test Method D323-82 for the measurement of Reid vapor
pressure, adjusted for actual storage temperature in accordance with API
Publication 2517, Third Edition, 1989; or
6. additional performance test procedures, or
equivalent test methods, approved by the administrative authority*.
D. Recordkeeping. The
owner/operator of any single or multiple compartment volatile organic compound
water separator shall maintain records to verify compliance with or exemption
from LAC 33:III.2109. The records shall be maintained for at least two years
and will include but not be limited to the following:
1. results of the monthly visual inspections
and the results of other tests performed in accordance with LAC
33:III.2109.C;
2. measurement of
the volume and true vapor pressure of the volatile organic compound(s)
recovered by the separator to demonstrate continuous compliance with the
criteria for exempted facilities; and
3. the date and reason for any maintenance
and repair of the applicable control devices.
