Current through August 26, 2024
(1) APPLICABILITY
AND DESIGNATION OF AFFECTED FACILITY.
(a) The
affected facility to which the provisions of this section apply is the total of
all the loading racks at a bulk gasoline terminal which deliver liquid product
into gasoline tank trucks.
(b) Each
facility under par. (a), the construction or modification of which is commenced
after December 17, 1980, is subject to the provisions of this section.
(c) For purposes of this section
any replacement of components of an existing facility described in par. (a),
commenced before August 18, 1983 in order to comply with any emission standard
adopted by the department, will not be considered a reconstruction under the

terminal's vapor collection system.
(g) The owner or operator shall act to assure
that the terminal's and the tank truck's vapor collection systems are connected
during each loading of a gasoline tank truck at the affected facility. Examples
of actions to accomplish this include training drivers in the hookup procedures
and posting visible reminder signs at the affected loading racks.
(h) The vapor collection and liquid loading
equipment shall be designed and operated to prevent gauge pressure in the
delivery tank from exceeding 4,500 pascals (450 mm of water) during product
loading. This level is not to be exceeded when measured by the procedures
specified in sub. (4) (d).
(i) No
pressure-vacuum vent in the bulk gasoline terminal's vapor collection system
may begin to open at a system pressure less than 4,500 pascals (450 mm of

handling gasoline shall be inspected during the loading of gasoline tank trucks
for total organic compounds liquid or vapor leaks. For purposes of this
paragraph detection methods incorporating sight, sound, or smell are
acceptable. Each detection of a leak shall be recorded and the source of the
leak repaired within 15 calendar days after it is detected.
(4) TEST METHODS AND PROCEDURES.
(a) In conducting the performance tests
required in s.
NR 440.08, the
owner or operator shall use as reference methods and procedures the test
methods in Appendix A of 40 CFR part 60, incorporated by reference in s.
NR 440.17, or other methods and procedures as specified
in this subsection, except as provided in s.
NR 440.08(2). The 3-run requirement of
s.
NR 440.08(6) does not apply to this
section.
(b) Immediately before the
performance test required to determine compliance with sub. (3) (b), (c) and
(h), the owner or operator shall use Method 21 to monitor for leakage of vapor
all potential sources in the terminal's vapor collection system equipment while
a gasoline tank truck is being loaded. The owner or operator shall repair all
leaks with readings of 10,000 ppm (as methane) or greater before conducting the
performance test.
(c) The owner or
operator shall determine compliance with the standards in sub. (3) (b) and (c)
as follows:
1. The performance test shall be
6 hours long during which at least 300,000 liters of gasoline is loaded. If
this is not possible, the test may be continued the same day until 300,000
liters of gasoline is loaded or the test may be resumed the next day with
another complete 6-hour period. In the latter case, the 300,000-liter criterion
need not be met. However, as much as possible, testing should be conducted
during the 6-hour period in which the highest throughput normally
occurs.
2. If the vapor processing
system is intermittent in operation, the performance test shall begin at a
reference vapor holder level and shall end at the same reference point. The
test shall include at least two startups and shutdowns of the vapor processor.
If this does not occur under automatically controlled operations, the system
shall be manually controlled.
3.
The emission rate (E) of total organic compounds shall be computed using the
following equation:
where:
E is the emission rate of total organic compounds,
mg/liter of gasoline loaded
See PDF for
diagram
Vesi is the volume of air-vapor mixture exhausted at each
interval"i", scm
Cei is the concentration of total organic compounds at
each interval "i", ppm
L is the total volume of gasoline loaded, liters
n is the number of testing interval
i is the emission testing interval of 5 minutes
K is the density of calibration gas, 1.83 10 6 for propane
and 2.41 106 for butane, mg/scm
4. The performance test shall be conducted in
intervals of 5 minutes. For each interval "i", readings from each measurement
shall be recorded, and the volume exhausted (Vesi) and the corresponding
average total organic compounds concentration (Cei) shall be determined. The
sampling system response time shall be considered in determining the average
total organic compounds concentration corresponding to the volume
exhausted.
5. The following methods
shall be used to determine the volume (Vesi) air-vapor mixture exhausted at
each interval:
a. Method 2B shall be used for
combustion vapor processing systems.
b. Method 2A shall be used for all other
vapor processing systems.
6. Method 25A or 25B shall be used for
determining the total organic compounds concentration (Cei) at each interval.
The calibration gas shall be either propane or butane. The owner or operator
may exclude the methane and ethane content in the exhaust vent by any method,
for example, Method 18, approved by the department.
7. To determine the volume (L) of gasoline
dispensed during the performance test period at all loading racks whose vapor
emissions are controlled by the processing system being tested, terminal
records or readings from gasoline dispensing meters at each loading rack shall
be used.
(d) The owner
or operator shall determine compliance with the standard in sub. (3) (h) as
follows:
1. A pressure measurement device,
liquid manometer, magnehelic gauge or equivalent instrument, capable of
measuring up to 500 mm of water gauge pressure with "2.5 mm of water precision,
shall be calibrated and installed on the terminal's vapor collection system at
a pressure tap located as close as possible to the connection with the gasoline
tank truck.
2. During the
performance test, the pressure shall be recorded every 5 minutes while a
gasoline truck is being loaded; the highest instantaneous pressure that occurs
during each loading shall also be recorded. Every loading position shall be
tested at least once during the performance test.
(e) The performance test requirements of par.
(c) do not apply to flares defined in sub. (2) and meeting the requirements in
s.
NR 440.18(2)
