A.
Affected
facilities
(1) This regulation applies
to any facility that emits or has the potential to emit forty (40) tons or more
of VOC per calendar year.
In determining a facility's potential to emit VOC, total VOC
emissions includes all VOC emissions occurring at the facility from
VOC-emitting equipment or processes, except VOC emissions from equipment
exempted in Section 1(C) of this Chapter. Emissions of VOC emitting activities
from general maintenance shall be included to the extent possible.
(2) Any facility subject to this
Chapter that has potential to emit 40 tons per year or more but did not have
actual emissions of forty (40) tons or more of VOC per calendar year since
January 1, 1987, may be exempt from the requirements of Sections 3 and 4 of
this Chapter under the requirements stated in Section 6 of this rule.
Each owner or operator of a facility that is initially exempt
from the requirements of Sections 3 and 4 and then becomes subject to this
Chapter under the applicability threshold provisions of Section 1(A) of this
Chapter must notify the Department, in writing, of its applicability within
thirty (30) days and must comply with the provisions and schedules specified in
Section 3 with final compliance no longer than two (2) years after becoming
subject to this Chapter.
(3) Any facility subject to this Chapter with
actual emissions greater than 40 tons per year but less than 50 tons VOC per
calendar year actual emissions, since January 1, 1987, that elects to amend its
license and accept license restrictions under the 40 tons of VOC per year
potential to emit at the time of the RACT applicability determination, may be
exempt from the applicability of this Chapter.
(4) As of the effective date of the 1995
amendment to this Chapter, the following VOC-emitting equipment or processes
are no longer exempt from this rule: offset lithography, volatile organic
liquid storage tanks, industrial wastewater, wood furniture, plastic parts
coating (business machines), plastic parts coating (other), autobody
refinishing, clean up solvents, ship building, aerospace coating and SOCMI
batch processes.
NOTE: The above VOC-emitting equipment and processes were
previously exempt pursuant to Section 1(C)(3) of this rule as promulgated in
1993 because EPA had listed them as categories for which CTGs were under
development pursuant to a list in Appendix E of the General Preamble of Title I
(57 Federal Register 18077). The CTG's have not been developed and the CAAA
requires states to adopt rules for these sources by November 15, 1994.
B.
Applicable
Effective Dates. This regulation shall be applicable in all regions of
the State of Maine as follows:
(1) For
affected facilities subject to Sections 1(A)(1) and 1(A)(2) of this rule, the
applicable effective date is October 17, 1993, except
(2) For affected facilities subject to
Section 1(A)(4) of this rule, the applicable effective date is February 15,
1995, and
C.
Exempted VOC-emitting equipment or processes. The following VOC-emitting
equipment or processes are exempted in determining a facility's total VOC
emissions:
(1) VOC-emitting equipment or
processes that are subject to regulation under 40 CFR Part 61: National
Emission Standards for Hazardous Air Pollutants (NESHAPS);
(2) VOC-emitting equipment or processes that
achieve Best Available Control Technology
for VOC or the Lowest Achievable Emission Rate for VOC, as determined by the
Department and imposed in an air emission license which contains specific
emission limitations for all affected VOC-emitting equipment or processes and
was issued pursuant to federally approved permitting regulations or regulations
promulgated by the Environmental Protection Agency (EPA);
(3) VOC-emitting equipment or processes that
receive RACT, as determined by the Department in accordance with the following:
(a) Pursuant to a VOC control regulation
approved by the EPA for which a Control Techniques Guideline (CTG) document was
written, or
(b) As contained in a
federally enforceable air emission license issued by the Department prior to
the applicable effective date;
(4) VOC-emitting equipment from which the
VOCs emitted are from the incomplete combustion of any material, except where
material is heated, burned, combusted or otherwise chemically changed under
oxygen-deficient conditions by design;
(5) Kraft Recovery Boilers;
(6) Indirect contact wood kilns and wood
yards; and
(7) Paper machine area
emissions which include paper machines, and the finishing and converting
areas.
