La. Admin. Code tit. 33 § V-3019

Current through Register Vol. 50, No. 9, September 20, 2024

Section V-3019 - Low Risk Waste Exemption

A. Waiver of DRE Standard. The DRE standard of LAC 33:V.3009.A does not apply if the boiler or industrial furnace is operated in conformance with LAC 33:V.3019.A.1 and the owner or operator demonstrates by procedures prescribed in LAC 33:V.3019.A.2 that the burning will not result in unacceptable adverse health effects.

1. The device shall be operated as follows:

a. a minimum of 50 percent of fuel fired to the device shall be fossil fuel, fuels derived from fossil fuel, tall oil, or, if approved by the administrative authority on a case-by-case basis, other nonhazardous fuel with combustion characteristics comparable to fossil fuel. Such fuels are termed "primary fuel" for purposes of this Section. (Tall oil is a fuel derived from vegetable and rosin fatty acids.) The 50 percent primary fuel firing rate shall be determined on a total heat or mass input basis, whichever results in the greater mass feed rate of primary fuel fired;

b. primary fuels and hazardous waste fuels shall have a minimum as-fired heating value of 8,000 Btu/lb;

c. the hazardous waste is fired directly into the primary fuel flame zone of the combustion chamber; and

d. the device operates in conformance with the carbon monoxide controls provided by LAC 33:V.3009.B.1. Devices subject to the exemption provided by this Section are not eligible for the alternative carbon monoxide controls provided by LAC 33:V.3009.C.

2. Procedures to demonstrate that the hazardous waste burning will not pose unacceptable adverse public health effects are as follows.

a. Identify and quantify those nonmetal compounds listed in LAC 33:V.4901.G, Table 6 that could reasonably be expected to be present in the hazardous waste. The constituents excluded from analysis must be identified and the basis for their exclusion explained.

b. Calculate reasonable, worst-case emission rates for each constituent identified in LAC 33:V.3019.A.2.a of this Section by assuming the device achieves 99.9 percent destruction and removal efficiency. That is, assume that 0.1 percent of the mass weight of each constituent fed to the device is emitted.

c. For each constituent identified in LAC 33:V.3019.A.2.a, use emissions dispersion modeling to predict the maximum annual average ground level concentration of the constituent:

i. dispersion modeling shall be conducted using methods specified in LAC 33:V.3013;

ii. owners or operators of facilities with more than one on-site stack from a boiler or industrial furnace that is exempt under this Section must conduct dispersion modeling of emissions from all stacks exempt under this Section to predict ambient levels prescribed by this Paragraph.

d. Ground level concentrations of constituents predicted under LAC 33:V.3019.A.2.c must not exceed the following levels:

i. for the noncarcinogenic compounds listed in 40 CFR 266, Appendix IV, as adopted and amended at LAC 33:V.3099.Appendix D, the levels established in 40 CFR 266, Appendix IV, as adopted and amended at LAC 33:V.3099.Appendix D;

ii. for the carcinogenic compounds listed in 40 CFR 266, Appendix V, as adopted at LAC 33:V.3099.Appendix E, the sum for all constituents of the ratios of the actual ground level concentration to the level established in 40 CFR 266, Appendix V, as adopted at LAC 33:V.3099.Appendix E, cannot exceed 1.0; and

iii. for constituents not listed in 40 CFR 266, Appendices IV or V, as adopted and amended at LAC 33:V.3099.Appendices D and E, 0.1 micrograms per cubic meter.

B. Waiver of Particulate Matter Standard. The particulate matter standard of LAC 33:V.3013 does not apply if:

1. the DRE standard is waived under LAC 33:V.3019.A; and

2. the owner or operator complies with the Tier I or adjusted Tier I metals feed rate screening limits provided by LAC 33:V.3013.B or E.
