Current through Register Vol. 50, No. 9, September 20, 2024
A. Applicability
1. The following loading facilities for
volatile organic compounds having a true vapor pressure at loading conditions
of 1.5 psia (10.3 kPa) or greater must comply with the requirements of
Subsections B-F of this Section when servicing tanks, trucks or trailers which
have individual capacities in excess of 200 gallons (760 liters):
a. 20,000 gallons (75,700 liters) or more
throughput per day (averaged over any 30-day period), for operations (all
facilities on premises) for which construction commenced after May 20, 1979;
or
b. 40,000 gallons (151,400
liters) or more throughput per day (averaged over any 30-day period), for
operations (all facilities on premises) for which construction commenced prior
to May 20, 1979.
2. Once
a facility is subject to this Section, it must remain in compliance with the
requirements of Subsections B-F of this Section, even during periods in which
its throughput is below the applicability levels.
B. Control Requirements. The facility must be
equipped with a vapor collection system properly installed, and in good working
order. The vapor collection system shall consist of, at a minimum, a vapor
return line which returns to the VOC dispensing vessel or to a disposal system
all vapors displaced during loading. In the event a disposal system is used, it
shall have a destruction/removal efficiency as referenced at Subsection E of
this Section (demonstrated to the satisfaction of the Louisiana Department of
Environmental Quality) of no less than 90 percent. Examples of vapor disposal
systems include but are not limited to incinerators, flares, carbon adsorbers
or chillers. Provisions must be made to prevent spills during the attachment
and disconnection of filling lines or arms. Loading and vapor lines must be
equipped with fittings which close automatically when disconnected, or must be
equipped to permit residual VOC in the loading line to discharge into a
collection system or disposal or recycling system.
C. Monitoring. No liquid or gaseous leaks
shall exist during loading or unloading operations. Inspection for visible
liquid leaks, visible fumes, or significant odors resulting from VOC dispensing
operations shall be conducted by the owner or operator of the VOC loading
facility or the owner or operator of the tank, truck, or trailer. VOC loading
or unloading through the affected transfer lines shall be discontinued
immediately when a leak is observed and shall not be resumed until the observed
leak is repaired.
D. Recordkeeping.
The owner or operator of any VOC loading facility shall maintain the following
information on the premises for at least two years and shall make such
information available to representatives of the Louisiana Department of
Environmental Quality upon request:
1. a daily
record of the total throughput of VOC loaded at the facility; and
2. for VOC loading operations subject to the
requirements of this Section:
a. a daily
record of the number of delivery vessels loaded at the facility and the
quantity and type of VOC loaded to each delivery vessel;
b. a record of any leaks found at the
facility in accordance with the provisions specified in Subsection C of this
Section and the corrective action taken;
c. a record of the results of any testing
conducted at the facility in accordance with the provisions specified in
Subsection E of this Section.
3. For vapor disposal systems, the following
information shall be recorded:
a. daily
measurements of the exhaust gas temperature immediately downstream of a
direct-flame incinerator;
b. daily
measurements of the inlet and outlet temperature of a chiller or catalytic
incinerator; and
c. breakthrough of
VOCs in a carbon adsorption unit.
4. The date and reason for any maintenance
and repair of the applicable control devices and the estimated quantity and
duration of volatile organic compound emissions during such activities shall be
recorded.
E. Test
Methods
1. Compliance with Subsection B of
this Section shall be determined by applying the following test methods, as
appropriate:
a. Test Methods 1-4 (40 CFR Part
60, Appendix A, as incorporated by reference in LAC 33:III.3003) for
determining flow rates, as necessary;
b. Test Method 18 ( 40 CFR Part 60, Appendix
A, as incorporated by reference in LAC 33:III.3003) for determining gaseous
organic compounds emissions by gas chromatography;
c. Test Method 25 (40 CFR Part 60, Appendix
A, as incorporated by reference in LAC 33:III.3003) for determining total
gaseous non-methane organic emissions as carbon;
d. Test Method 25A or 25B (40 CFR Part 60,
Appendix A, as incorporated by reference in LAC 33:III.3003) for determining
total gaseous organic concentration using flame ionization or nondispersive
infrared analysis; and
e. flaring
devices, which shall be designed and operated according to
40 CFR
60.18.
2. 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.
3. Within 60 days of test completion, a copy
of the test results shall be submitted to the Office of Environmental Services
for review and approval.
F. Exemptions. This Section does not apply to
(a) crude or condensate loading facilities, (b) ship and barge loading
operations, and (c) gasoline loading facilities which are regulated under
Subchapter F.
