Current through Register Vol. 43, No. 39, September 26, 2024
(a) The provisions
of this regulation shall apply to any facility that:
(1) Uses, produces, or stores ethanol or
methanol;
(2) has a volatile
organic compound (VOC) potential contaminant emission rate of 100 tons per year
or greater;
(3) is located in an
area which has been identified as not meeting the national primary ambient air
quality standard for ozone in the manner prescribed by the provisions of the
federal clean air act, 42 U.S.C. 7407 as promulgated at 40 CFR Part 81, as in
effect July 1, 1989.
(b) For purposes of this regulation, the
potential contaminant emission rate shall be determined as the sum of all
potential VOC emissions from point and fugitive sources, including any VOC's
present in the wastewater stream, 100 percent of which are presumed to be
emitted to the atmosphere.
(c) VOC
emission sources are:
(1) Point sources,
which include process tanks, alcohol storage tanks, wastewater vents, and
wastewater VOC removal devices; and
(2) fugitive sources, which include all
sources of VOC emissions other than point sources, including leaking valves,
compressors, pumps, gauges, open-ended lines, sample flanges, and other sources
of fugitive emissions including alcohol loading and unloading operations.
(d) The owner or
operator of an affected facility shall control VOC emissions from process tanks
and alcohol storage tanks by installing and operating the following, singly or
in combination:
(1) Retrofitting the tanks
with an internal or external floating roof. Internal and external floating roof
tanks shall be designed and constructed to meet or exceed the design
specifications found at 40 CFR Part 60, Subpart Kb, as in effect July 1, 1989;
or
(2) retrofitting the tanks with
a vapor collection system and control device to reduce VOC emissions by 95 per
cent, by weight or greater. Vapor collection systems and control devices
installed pursuant to this regulation shall be operated at all times when
emissions may be vented to them.
(e) The owner or operator of an affected
facility shall reduce the VOC concentration in process wastewater by 90 percent
by weight or greater, less any credit for VOC reductions achieved through
pollution prevention, by:
(1) installing a
wastewater VOC recovery device or devices to remove and capture VOC's contained
in process wastewater streams for recovery or destruction using a control
device pursuant to subsection (f); or
(2) taking credit for preventing VOC's from
entering the wastewater stream through pollution prevention actions such as
equipment or technology modifications, process or procedure modifications,
reformulation or redesign of products, substitution of raw materials, and
improvements in housekeeping, maintenance, training, or inventory control.
(f) The owner or
operator of an affected facility shall control VOC emissions from wastewater
point sources by installing and operating a device or devices to collect and
recover or destroy VOC's from wastewater point sources to reduce VOC emissions
by 95 percent, by weight, or greater. For treatment purposes, emissions from
wastewater point sources may be combined, in a common vapor collection system
or systems, with emissions collected from process tanks and alcohol storage
tanks to achieve 95 percent reduction of VOC's by weight, or greater.
(g) The owner or operator of an
affected facility shall minimize VOC emissions from fugitive sources by
developing a fugitive source emission control plan which shall be submitted to
the department within 12 months after the effective date of this regulation or
upon commencing operation of the affected facility, whichever is later.
(1) The plan shall include a description of
the control strategy and a testing program to evaluate the percent reduction of
VOC emissions.
(2) The approved
control strategy and testing program shall be implemented and the results of
testing submitted to the department within six months of the department's
approval of the plan.
(3) The
fugitive source emission control plan shall be designed to achieve at least 50
percent control efficiency.
(h) During compliance demonstrations under
subsections (d), (e), or (f):
(1) The
averaging time for percent reduction requirements for gaseous VOC streams shall
be the duration of the 40 CFR Part 60, Appendix A, reference method 25,
performance test, as in effect July 1, 1989. Control equipment parameters,
measured by continuous monitoring devices, shall indicate whether control
equipment is properly operated and maintained; and
(2) the averaging time for percent reduction
requirements for process wastewater streams shall be daily, confirmed by at
least one daily sample of the process wastewater stream at both the inlet and
outlet of the control device.
(i) No later than eighteen months after the
effective date of this regulation or within 180 days of completion of control
equipment installation, whichever date occurs first, the owner or operator of
an affected facility shall conduct performance tests to demonstrate compliance
with the applicable VOC control requirements found in subsections (d), (e), (f)
and (g). If the performance test will not be conducted within 12 months after
an existing facility becomes subject to this regulation, a final control plan
shall be submitted to the secretary by December 31, 1991 for approval. This
plan shall include the following:
(1) a
detailed plan for process modifications; and
(2) a time schedule for compliance containing
increments of progress and a final compliance date.
(j) The owner or operator of an affected
facility shall conduct performance tests to demonstrate compliance with the
applicable percent reduction requirements found in subsections (d) and (f) in
accordance with 40 CFR Part 60, Appendix A, reference method 25 or reference
method 25A, as in effect July 1, 1989, and other applicable approved EPA
reference methods for gaseous streams and demonstrate compliance with the
applicable percent reduction requirement found in subsection (e) by methods
approved by the department for process wastewater streams. All monitoring
equipment shall be installed and calibrated prior to commencement of
performance tests.
(k) The owner
or operator of an affected facility shall conduct an initial performance
evaluation for all tanks retrofitted with an internal or external floating roof
in accordance with the testing requirements found at
40 CFR
60.113b, as in effect on July 1, 1989.
