Current through all regulations passed and filed through December 16, 2024
(A) Destruction and removal efficiency (DRE)
standard.
(1) General. Except as provided in
paragraph (A)(3) of this rule, a boiler or industrial furnace burning hazardous
waste shall achieve a DRE of 99.99 per cent for all organic hazardous
constituents in the waste feed. To demonstrate conformance with this
requirement, 99.99 per cent DRE shall be demonstrated during a trial burn for
each principal organic hazardous constituent (POHC) designated [under paragraph
(A)(2) of this rule] in the boiler's or
industrial furnace's permit for each waste feed. DRE is determined for
each POHC from the following equation:
DRE = 1 [ 1 - (Wout / Win) ] x 100
where:
Win = mass feed rate of one POHC in the hazardous
waste fired to the boiler or industrial furnance.
Wout = mass emission rate
of the same POHC present in stack gas prior to release to the
atmosphere.
(2) Designation
of POHCs. POHCs are those compounds for which compliance with the DRE
requirements of this rule shall be demonstrated in a trial burn in conformance
with procedures prescribed in rule
3745-50-66 of the Administrative
Code. One or more POHCs shall be designated by the director for each waste feed
to be burned. POHCs shall be designated based on the degree of difficulty of
destruction of the organic constituents in the waste and on
the organic
constituents' concentrations or mass in the waste feed considering the
results of waste analyses submitted with "Part B" of the permit application.
POHCs are most likely to be selected from among those compounds listed in the
appendix to rule
3745-51-11 of the Administrative
Code that are also present in the normal waste feed. However, if the applicant
demonstrates to the director's satisfaction that a compound not listed in the
appendix to rule
3745-51-11 of the Administrative
Code or not present in the normal waste feed is a suitable indicator of
compliance with the DRE requirements of this rule, that compound may be
designated as a POHC. Such POHCs need not be toxic or organic
compounds.
(3) Dioxin-listed waste.
A boiler or industrial furnace burning hazardous waste containing (or derived
from) EPA hazardous waste numbers F020, F021, F022, F023, F026, or F027 shall
achieve a DRE of 99.9999 per cent for each POHC designated [under paragraph
(A)(2) of this rule] in the boiler's or
industrial furnace's permit. This performance shall be demonstrated on
POHCs that are more difficult to burn than tetra-, penta-, and
hexachlorodibenzo-p-dioxins and dibenzofurans. DRE is determined for each POHC
from the equation in paragraph (A)(1) of this rule. In addition, the owner or
operator of the boiler or industrial furnace shall notify the director of
intent to burn EPA hazardous waste numbers F020, F021, F022, F023, F026, or
F027.
(4) Automatic waiver of DRE
trial burn. Owners and operators of boilers operated under the special
operating requirements provided by rule
3745-266-110 of the
Administrative Code are considered to be in compliance with the DRE standard of
paragraph (A)(1) of this rule and are exempt from the DRE trial burn.
(5) Low risk waste. Owners and operators of
boilers or industrial furnaces that burn hazardous waste in compliance with
paragraph (A) of rule 3745- 266-109 of the Administrative Code are considered
to be in compliance with the DRE standard of paragraph (A)(1) of this rule and
are exempt from the DRE trial burn.
(B) Carbon monoxide standard.
(1) Except as provided in paragraph (C) of
this rule, the stack gas concentration of carbon monoxide from a boiler or
industrial furnace burning hazardous waste cannot exceed one hundred parts per
million by volume (ppmv) on an hourly rolling average basis (i.e., over any
sixty-minute period), continuously corrected to seven
per cent oxygen, dry gas basis.
(2)
Carbon monoxide and oxygen shall be continuously monitored in conformance with
"Performance Specifications for Continuous Emission Monitoring of Hydrocarbons
for Incinerators, Boilers, and Industrial Furnaces Burning Hazardous Waste" in
the appendix to rule
3745-266-103 of the
Administrative Code.
(3) Compliance
with the one hundred ppmv carbon monoxide limit shall be demonstrated during
the trial burn (for new facilities or a permit by rule facility applying for a
permit) or the compliance test (for permit by rule facilities). To demonstrate
compliance, the highest hourly rolling average carbon monoxide level during any
valid run of the trial burn or compliance test shall not exceed one hundred
ppmv.
(C) Alternative
carbon monoxide standard.
(1) The stack gas
concentration of carbon monoxide from a boiler or industrial furnace burning
hazardous waste may exceed the one hundred ppmv limit provided that stack gas
concentrations of hydrocarbons do not exceed twenty ppmv, except as provided by
paragraph (F) of this rule for certain industrial furnaces.
(2) Hydrocarbon limits shall be established
under this rule on an hourly rolling average basis (i.e., over any
sixty-minute period), reported as propane, and
continuously corrected to seven per cent oxygen, dry gas basis.
(3) Hydrocarbons shall be continuously
monitored in conformance with "Performance Specifications for Continuous
Emission Monitoring of Hydrocarbons for Incinerators, Boilers, and Industrial
Furnaces Burning Hazardous Waste" in the appendix to rule
3745-266-103 of the
Administrative Code. Carbon monoxide and oxygen shall be continuously monitored
in conformance with paragraph (B)(2) of this rule.
(4) The alternative carbon monoxide standard
is established based on carbon monoxide data during the trial burn (for a new
facility) and the compliance test (for a permit by rule facility). The
alternative carbon monoxide standard is the average over all valid runs of the
highest hourly average carbon monoxide level for each run. The carbon monoxide
limit is implemented on an hourly rolling average basis, and continuously
corrected to seven per cent oxygen, dry gas basis.
(D) Special requirements for furnaces. Owners
and operators of industrial furnaces (e.g., kilns, cupolas) that feed hazardous
waste for a purpose other than solely as an ingredient [see paragraph (A)(5)(b)
of rule 3745-266-103 of the
Administrative Code] at any location other than the end where products are
normally discharged and where fuels are normally fired shall comply with the
hydrocarbon limits provided by paragraph (C) or (F) of this rule irrespective
of whether stack gas carbon monoxide concentrations meet the one hundred ppmv
limit of paragraph (B) of this rule.
(E) Controls for dioxins and furans. Owners
and operators of boilers and industrial furnaces that are equipped with a dry
particulate matter control device that operates within the temperature range of
four hundred fifty to seven hundred fifty degrees Fahrenheit, and industrial
furnaces operating under an alternative hydrocarbon limit established under
paragraph (F) of this rule shall conduct a site-specific risk assessment as
follows to demonstrate that emissions of chlorinated dibenzo-p-dioxins and
dibenzofurans do not result in an increased lifetime cancer risk to the
hypothetical maximum exposed individual exceeding one in one hundred thousand:
(1) During the trial burn (for new facilities
or a permit by rule facility applying for a permit) or compliance test (for
permit by rule facilities), determine emission rates of the tetra- to octa-
congeners of chlorinated dibenzo-p-dioxins and dibenzofurans (CDDs and CDFs)
using method 0023A, "Sampling Method for Polychlorinated Dibenzo-p-Dioxins and
Polychlorinated Dibenzofurans Emissions from Stationary Sources," U.S. EPA
publication SW-846;
(2)
Estimate the 2,3,7,8-TCDD toxicity equivalence of the tetra- to octa- CDDs and
CDFs congeners using "Procedures for Estimating the Toxicity Equivalence of
Chlorinated Dibenzo-p-dioxin and Dibenzofuran Congeners" in the appendix to
rule 3745-266-103 of the
Administrative Code. Multiply the emission rates of CDD and CDF congeners with
a toxicity equivalence greater than zero (see the procedure) by the calculated
toxicity equivalence factor to estimate the equivalent emission rate of
2,3,7,8-TCDD;
(3) Conduct
dispersion modeling using methods recommended in 40 CFR Part 51 appendix W
["Guideline on Air Quality Models (Revised)" and any supplements],
the "Hazardous Waste Combustion Air Quality Screening Procedure," provided in
the appendix to rule
3745-266-103 of the
Administrative Code, or in "Screening Procedures for Estimating the Air Quality
Impact of Stationary Sources, Revised" to predict the maximum annual average
off-site ground level concentration of 2,3,7,8-TCDD equivalents determined
under paragraph (E)(2) of this rule. The maximum annual average concentration
shall be used when a person resides on-site; and
(4) The ratio of the predicted maximum annual
average ground level concentration of 2,3,7,8-TCDD equivalents to the
risk-specific dose for 2,3,7,8-TCDD provided in appendix B to rule
3745-266-109 of the
Administrative Code (2.2 x 10-7) shall not exceed
1.0.
(F) Monitoring
carbon monoxide and hydrocarbons in the by-pass duct of a cement kiln. Cement
kilns may comply with the carbon monoxide and hydrocarbon limits provided by
paragraphs (B), (C), and (D) of this rule by monitoring in the by-pass duct
provided that both:
(1) Hazardous waste is
fired only into the kiln and not at any location downstream from the kiln exit
relative to the direction of gas flow.
(2) The by-pass duct diverts a minimum of ten
per cent of kiln off-gas into the duct.
(G) Use of emissions test data to demonstrate
compliance and establish operating limits. Compliance with this rule shall be
demonstrated simultaneously by emissions testing or during separate runs under
identical operating conditions. Further, data to demonstrate compliance with
the carbon monoxide and hydrocarbon limits of this rule or to establish
alternative carbon monoxide or hydrocarbon limits under this rule shall be
obtained during the time that DRE testing, and where applicable, CDD and CDF
testing under paragraph (E) of this rule and comprehensive organic emissions
testing under paragraph (F) of this rule is conducted.
(H) Enforcement. For the purposes of permit
enforcement, compliance with the operating requirements specified in the permit
(under rule
3745-266-102 of the
Administrative Code) will be regarded as compliance with this rule. However,
evidence that compliance with those permit conditions is insufficient to ensure
compliance with this rule may be information justifying modification of a
permit under rule
3745-50-51 of the Administrative
Code.
