Section 726.207 - Standards to Control HCl and Chlorine Gas Emissions
Current through Register Vol. 48, No. 38, September 20, 2024
a) General. The owner or operator must comply with the HCl and chlorine gas controls provided by subsection (b), (c), or (e).
b) Screening Limits
c) Tier III Site-Specific Risk Assessments
d) Averaging Periods. The HCl and chlorine gas controls are implemented by limiting the feed rate of total chlorine and chloride in all feedstreams, including hazardous waste, fuels, and industrial furnace feed stocks. Under Tier I, the feed rate of total chlorine and chloride is limited to the Tier I Screening Limits. Under Tier II and Tier III, the feed rate of total chlorine and chloride is limited to the feed rates during the trial burn (for new facilities or an interim status facility applying for a permit) or the compliance test (for interim status facilities). The feed rate limits are based on either of the following:
e) Adjusted Tier I Feed Rate Screening Limits. The owner or operator may adjust the feed rate screening limit provided by Appendix B to account for site-specific dispersion modeling. Under this approach, the adjusted feed rate screening limit is determined by back-calculating from the acceptable ambient level for chlorine gas provided by Appendix D using dispersion modeling to determine the maximum allowable emission rate. This emission rate becomes the adjusted Tier I feed rate screening limit.
f) Emissions Testing. Emissions testing for HCl and chlorine gas (Cl2) must be conducted using the procedures described in Method 0050 or 0051, in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", USEPA publication number EPA-530/SW-846, incorporated by reference in 35 Ill. Adm. Code 720.111(a).
g) Dispersion Modeling. Dispersion modeling must be conducted according to the provisions of Section 726.206(h).
h) Enforcement. For the purposes of permit enforcement, compliance with the operating requirements specified in the permit (under Section 726.202) 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 is "information" justifying modification or revocation and re-issuance of a permit under 35 Ill. Adm. Code 703.270 through 703.273.
