Current through Register Vol. 50, No. 9, September 20, 2024
A boiler or industrial furnace burning hazardous waste
must be designed, constructed, and maintained so that, when operated in
accordance with operating requirements specified under LAC 33:V.3005.E, it will
meet the following standards.
A. DRE
Standard. A boiler or industrial furnace burning hazardous waste must meet the
destruction and removal efficiency (DRE) performance standard of LAC 33:V.3009.
1. General. A boiler or industrial furnace
burning hazardous waste must achieve a DRE of 99.99 percent for all organic
hazardous constituents in the waste feed. To demonstrate conformance with this
requirement, 99.99 percent DRE must be demonstrated during a trial burn for
each principal organic hazardous constituent (POHC) designated under LAC
33:V.3009.A in its permit for each waste feed. DRE is determined for each POHC
from the following equation.

Win = mass feed rate of one POHC in
the hazardous waste fired to the boiler or industrial furnace
Wout = mass emission rate of the
same POHC present in stack gas prior to release to the atmosphere
2. Designation of POHCs. Principal
organic hazardous constituents (POHCs) are those compounds for which compliance
with the DRE requirements shall be demonstrated in a trial burn in conformance
with procedures prescribed in LAC 33:V.537. One or more POHCs will be specified
in the facility's permit 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 hazardous waste and on their concentrations or mass in the
waste feed, considering the results of hazardous waste analysis and trial burns
or alternative data submitted with Part II of the facility's permit
application. POHCs are most likely to be selected from among those compounds
listed in LAC 33:V.4901.G, Table 6 that are also present in the normal waste
feed. However, if the applicant demonstrates to the administrative authority's
satisfaction that a compound not listed in LAC 33:V.4901.G., Table 6 or not
present in the normal waste feed is a suitable indicator of compliance with the
DRE requirements of this Section, 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 must achieve a
DRE of 99.9999 percent for each POHC designated (under Subparagraph A.1.b of
this Section) in its permit. This performance must be demonstrated on POHCs
that are more difficult to burn than tetra-, penta-, and
hexachlorodibenzo-p-dioxins and dibenzofurans. The DRE is determined for each
POHC from the equation in Paragraph A.1 of this Section. In addition, the owner
or operator of the boiler or industrial furnace must notify the Office of
Environmental Services of his 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 LAC 33:V.3021 are
considered to be in compliance with the DRE standard of LAC 33:V.3009.A.1 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 the
requirements of LAC 33:V.3019.A are considered to be in compliance with the DRE
standard of LAC 33:V.3009.A.1 and are exempt from the DRE trial burn.
B. Carbon Monoxide Standard
1. Except as provided in LAC 33:V.3009.C, the
stack gas concentration of carbon monoxide (CO) from a boiler or industrial
furnace burning hazardous waste cannot exceed 100 ppmv on an hourly rolling
average basis (i.e., over any 60-minute period), continuously corrected to 7
percent oxygen, dry gas basis.
2.
CO and oxygen shall be continuously monitored in conformance with "Performance
Specifications for Continuous Emission Monitoring of Carbon Monoxide and Oxygen
for Incinerators, Boilers, and Industrial Furnaces Burning Hazardous Waste" in
40 CFR 266, Appendix IX, as adopted and amended at LAC 33:V.3099.Appendix
I.
3. Compliance with the 100 ppmv
CO limit must be demonstrated during the trial burn (for new facilities or an
interim status facility applying for a permit) or the compliance test (for
interim status facilities). To demonstrate compliance, the highest hourly
rolling average CO level during any valid run of the trial burn or compliance
test must not exceed 100 ppmv.
C. Alternative Carbon Monoxide Standard
1. The stack gas concentration of carbon
monoxide (CO) from a boiler or industrial furnace burning hazardous waste may
exceed the 100 ppmv limit provided that stack gas concentrations of
hydrocarbons (HC) do not exceed 20 ppmv, except as provided by LAC 33:V.3009.F
for certain industrial furnaces.
2.
HC limits must be established under this Section on an hourly rolling average
basis (i.e., over any 60-minute period), reported as propane, and continuously
corrected to 7 percent oxygen, dry gas basis.
3. HC 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 40 CFR 266, Appendix IX, as adopted and amended at LAC
33:V.3099.Appendix I. CO and oxygen shall be continuously monitored in
conformance with Paragraph B.2 of this Section.
4. The alternative CO standard is established
based on CO data during the trial burn (for a new facility) and the compliance
test (for an interim status facility). The alternative CO standard is the
average over all valid runs of the highest hourly average CO level for each
run. The CO limit is implemented on an hourly rolling average basis, and
continuously corrected to 7 percent oxygen, dry gas basis.
D. Special Requirements for Furnaces. Owners
or operators of industrial furnaces (e.g., kilns, cupolas) that feed hazardous
waste for a purpose other than solely as an ingredient (see LAC
33:V.3007.A.5.b) at any location other than the end where products are normally
discharged and where fuels are normally fired must comply with the hydrocarbon
limits provided by LAC 33:V.3009.C or F irrespective of whether stack gas CO
concentrations meet the 100 ppmv limit of LAC 33:V.3009.B.
E. Controls for Dioxins and Furans. Owners or
operators of boilers and industrial furnaces that are equipped with a dry
particulate matter control device that operates within the temperature range of
450-750°F, and industrial furnaces operating under an alternative hydrocarbon
limit established under LAC 33:V.3009.F must 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 (MEI) exceeding 1 in
100,000:
1. during the trial burn (for new
facilities or an interim status facility applying for a permit) or compliance
test (for interim status facilities), determine emission rates of the
tetra-octa congeners of chlorinated dibenzo-p-dioxins and dibenzofurans
(CDDs/CDFs) using Method 0023A, Sampling Method for Polychlorinated
Dibenzo-p-Dioxins and Polychlorinated Dibenzofurans Emissions from Stationary
Sources, EPA Publication SW-846, as incorporated by reference in LAC
33:V.110;
2. estimate the
2,3,7,8-TCDD toxicity equivalence of the tetra-octa CDD/CDF congeners using
"Procedures for Estimating the Toxicity Equivalence of Chlorinated
Dibenzo-p-Dioxin and Dibenzofuran Congeners" in 40 CFR 266, Appendix IX, as
adopted and amended at LAC 33:V.3099.Appendix I. Multiply the emission rates of
CDD/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 51, Appendix W ("Guideline on Air Quality Models
(Revised)" and its supplements), the "Hazardous Waste Combustion Air Quality
Screening Procedure" provided in 40 CFR 266, Appendix IX, as adopted and
amended at LAC 33:V.3099.Appendix I, or in "Screening Procedures for Estimating
the Air Quality Impact of Stationary Sources, Revised," as incorporated by
reference at LAC 33:V.110, 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 Section. The maximum annual average concentration must 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 40 CFR 266, Appendix V, as
adopted at LAC 33:V.3099.Appendix E, (2.2 X 10-7)
shall not exceed 1.0.
G. Monitoring CO and HC
in the By-Pass Duct of a Cement Kiln. Cement kilns may comply with the carbon
monoxide and hydrocarbon limits provided by LAC 33:V.3009.B-D by monitoring in
the by-pass duct provided that:
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; and
2. the by-pass duct diverts a minimum of 10
percent of kiln off-gas into the duct.
H. Use of Emissions Test Data to Demonstrate
Compliance and Establish Operating Limits. Compliance with the requirements of
this Section must be demonstrated simultaneously by emissions testing or during
separate runs under identical operating conditions. Further, data to
demonstrate compliance with the CO and HC limits of this Section or to
establish alternative CO or HC limits under this Section must be obtained
during the time that DRE testing, and where applicable, CDD/CDF testing under
LAC 33:V.3009.E and comprehensive organic emissions testing under LAC
33:V.3009.F is conducted.
I.
Enforcement. For the purposes of permit enforcement, compliance with the
operating requirements specified in the permit (under LAC 33:V.3005) will be
regarded as compliance with this Section. However, evidence that compliance
with those permit conditions is insufficient to ensure compliance with the
requirements of this Section may be "information" justifying modification or
revocation and re-issuance of a permit under LAC 33:V.323.
