Current through 2024-13, March 27, 2024
A.
Criteria Air Pollutant Emission
Statements. The owner or operator of any facility meeting the
applicability requirements in Section 1(B) must file an emission statement with
the Department on an annual basis for those criteria air pollutants listed in
Section 1(B) of this Chapter.
(1) For those
pollutants listed in Section 1(B), the emission statement shall be limited to
emissions from only equipment and processes required to be included in and
described in their air emission license.
(2)
De minimus emissions
need not be reported. For criteria pollutants, de minimus
emissions means those emissions, when aggregated on a facility basis, are less
than one percent (1%) of the minimum reporting threshold in Section
1(B).
B.
Greenhouse Gas Emission Statements. The owner or operator of any
facility meeting the applicability requirements in Sections 1(D) or (E) must
file an emission statement with the Department on an annual basis for those
greenhouse gases described in Section 1(C) of this Chapter.
(1) For those greenhouse gases described in
Section 1(C), the emission statement shall be limited to emissions from only
equipment and processes required to be included in and described in their air
emission license, with the exception of fugitive emissions of HFCs, PFCs and
SF6 greater than the de minimis reporting level.
(2)
De minimus emissions
need not be reported. For greenhouse gases, de minimus
emissions means those emissions, when aggregated on a facility basis, that are
less than one ton of carbon dioxide equivalents (CO2e), when calculated using
the global warming potentials listed in Appendix B.
C.
Hazardous Air Pollutant Emission
Statements. The owner or operator of any facility meeting the
applicability requirements in Sections 1(B) and 1(F) must file an emission
statement with the Department every three years, starting with data of
emissions from calendar year 2008 for those hazardous air pollutants subject to
reporting in Section 1(F).
(1) For hazardous
air pollutants subject to reporting in Section 1(F), the emission statement
shall be limited to emissions from only equipment and processes required to be
included in and described in their air emission license.
(2) The emissions statement must include all
hazardous air pollutant, which when taken in aggregate at the facility, exceed
the reporting threshold in Appendix A.
(3) Notwithstanding subsection 3(C)(2) and
the reporting thresholds in Appendix A, emissions of the following hazardous
air pollutants must be reported for all fuel burning or combustion equipment
required to be included and described in the air emission license:
(a) acetaldehyde;
(b) acrolein;
(c) arsenic and arsenic compounds;
(d) benzene;
(e) cadmium and cadmium compounds;
(f) chromium and chromium compounds - For the
purposes of reporting chromium and chromium compounds, the owner or operators
of the facility may report the total emissions for all chromium compounds or
the emissions of hexavalent and trivalent chromium individually, however, not
both the compounds and the metal in its oxidized forms;
(g) cobalt and cobalt compounds;
(h) dioxins - For the purposes of reporting
dioxin and dioxin-like compounds, if the total toxicity equivalents of dioxin
and dioxin-like compounds is over the 0.0002 pound threshold, the owner or
operator of the facility must report the quantities of the individual dioxin
isomers and dioxin-like compounds;
(i) formaldehyde;
(j) manganese and manganese
compounds;
(k) mercury and mercury
compounds;
(l) nickel and nickel
compounds; and
(m) polycyclic
organic matter - For the purposes of reporting polycyclic organic matter, a
owner or operator of a facility may report the sum total of polycyclic organic
matter emissions or the quantities of the individual components of the
polycyclic organic matter group, however, not both.
NOTE: This list of thirteen hazardous air pollutants
represents a subset of the Air Toxics Priority list, developed for the
Department by the Maine Air Toxics Initiative.
(4)
De minimus emissions
need not be reported. For hazardous air pollutants, de minimus
refers to those hazardous air pollutants that do not have to be counted towards
the reporting threshold determination if they are present in a mixture below
certain concentrations. Those concentrations are one percent (1%) for
non-carcinogens and one-tenth of one percent (0.1%) for hazardous air
pollutants which meet the OSHA carcinogen standard. There is no de
minimus concentration for persistent bioaccumulative toxic (PBT)
chemicals.
D. Emission
statements required by subsections 3(A) through 3(C) must be filed with the
Department no later than July 1 of the year following the inventory year.
Beginning with inventory year 2009, emission statements required by subsections
3(A) through 3(C) must be filed with the Department no later than May 15 of the
year following the inventory year.
NOTE: Beginning with the 2009 annual emissions inventory, the
inventory submission deadline will move from July 1 to May 15. The 2009 annual
emissions inventory must be reported no later than May 15,
2010.
