Current through Register Vol. 63, No. 3, March 1, 2024
No person may cause, suffer, allow, or permit the operation of
any affected municipal waste combustor unit in a manner that violates the
following emission limits and requirements:
(1) Before April 28, 2009, particulate matter
emissions from each unit must not exceed 27 milligrams per dry standard cubic
meter (0.012 grains per dry standard cubic foot) corrected to 7 percent oxygen.
On and after April 28, 2009, particulate matter emissions from each unit must
not exceed 25 milligrams per dry standard cubic meter (0.011 grains per dry
standard cubic foot) corrected to 7 percent oxygen.
(2) Opacity. The emission limit for opacity
exhibited by the gases discharged to the atmosphere from a designated facility
must not exceed 10 percent opacity as a 6-minute average.
(3) Municipal Waste Combustor Metals:
(a) Before April 28, 2009, cadmium emissions
from each unit must not exceed 0.040 milligrams per dry standard cubic meter
(0.000018 gr/dscf) corrected to 7 percent oxygen. On and after April 28, 2009,
cadmium emissions from each unit must not exceed 0.020 milligrams per dry
standard cubic meter (0.000008 gr/dscf) corrected to 7 percent
oxygen.
(b) Before April 28, 2009,
lead emissions from each unit must not exceed 0.44 milligrams per dry standard
cubic meter (0.00020 gr/dscf) corrected to 7 percent oxygen. On and after April
28, 2009, lead emissions from each unit must not exceed 0.20 milligrams per dry
standard cubic meter (0.00009 gr/dscf) corrected to 7 percent oxygen.
(c) Before April 28, 2009, mercury emissions
from each unit must not exceed 0.080 milligrams per dry standard cubic meter
(0.000035 gr/dscf) or 15 percent of the potential mercury emission
concentration (an 85 percent reduction by weight), corrected to 7 percent
oxygen, whichever is less stringent. On and after April 28, 2009, mercury
emissions from each unit must not exceed 0.050 milligrams per dry standard
cubic meter (0.000022 gr/dscf) or 15 percent of the potential mercury emission
concentration (an 85-percent reduction by weight), corrected to 7 percent
oxygen, whichever is less stringent.
(4) Sulfur dioxide (SO2) emissions from each
unit must not exceed 29 parts per million by volume or 25 percent of the
potential sulfur dioxide emission concentration (75-percent reduction by weight
or volume), corrected to 7 percent oxygen (dry basis), whichever is less
stringent. Compliance with this emission limit is based on a 24-hour daily
geometric mean.
(5) Hydrogen
chloride (HCl) emissions from each unit must not exceed 29 parts per million by
volume or 5 percent of the potential hydrogen chloride emission concentration
(95-percent reduction by weight or volume), corrected to 7 percent oxygen (dry
basis), whichever is less stringent.
(6) The dioxin/furan emissions from each unit
must not exceed:
(a) Before April 28, 2009,
60 nanograms per dry standard cubic meter (total mass), corrected to 7 percent
oxygen, for a municipal waste combustor unit that employs an electrostatic
precipitator-based emission control system;
(b) On and after April 28, 2009, 35 nanograms
per dry standard cubic meter (total mass), corrected to 7 percent oxygen, for a
municipal waste combustor unit that employs an electrostatic precipitator-based
emission control system;
(c) Before
April 28, 2009, 30 nanograms per dry standard cubic meter (total mass),
corrected to 7 percent oxygen, for a municipal waste combustor unit that does
not employ an electrostatic precipitator-based emission control system. On and
after April 28, 2009, 15 nanograms per dry standard cubic meter (total mass),
corrected to 7 percent oxygen, for a municipal waste combustor unit that does
not employ an electrostatic precipitator-based emission control
system.
(7) Emissions of
nitrogen oxides from each unit must not exceed 205 parts per million by volume
on a dry basis corrected to 7 percent oxygen.
(8) Fugitive Emissions:
(a) No owner or operator may cause or allow
visible emissions of combustion ash from an ash conveying system (including
conveyor transfer points) in excess of 5 percent of the observation period
(i.e., 9 minutes per 3-hour period), as determined by EPA Reference Method 22
observations, except as provided in subsections (b) and (c) of this
section.
(b) The emission limit
specified in subsection (a) of this section does not cover visible emissions
discharged inside buildings or enclosures of ash conveying systems; however,
the emission limit specified in subsection (a) of this section does cover
visible emissions discharged to the atmosphere from buildings or enclosures of
ash conveying systems.
(c) The
provisions specified in subsection (a) of this section do not apply during
maintenance and repair of ash conveying systems.
