Section NR 666.105 - Standards to control particulate matter(1) A boiler or industrial furnace burning hazardous waste may not emit particulate matter in excess of 180 milligrams per dry standard cubic meter (0.08 grains per dry standard cubic foot) after correction to a stack gas concentration of 7% oxygen, using procedures prescribed in 40 CFR part 60, appendix A, methods 1 to 5, incorporated by reference in s. NR 660.11, and ch. NR 666 Appendix IX.(2) An owner or operator meeting s. NR 666.109(2) for the low risk waste exemption is exempt from the particulate matter standard.(3) OXYGEN CORRECTION. (a) Measured pollutant levels shall be corrected for the amount of oxygen in the stack gas according to the formula: Pc = Pm × 14 /( E - Y)
where:
Pc is the corrected concentration of the pollutant in the stack gas, Pm is the measured concentration of the pollutant in the stack gas, E is the oxygen concentration on a dry basis in the combustion air fed to the device, and Y is the measured oxygen concentration on a dry basis in the stack.
(b) For devices that feed normal combustion air, E will equal 21%. For devices that feed oxygen-enriched air for combustion (that is, air with an oxygen concentration exceeding 21%), the value of E will be the concentration of oxygen in the enriched air.(c) Compliance with all emission standards provided by this subchapter shall be based on correcting to 7% oxygen using this procedure.(4) For the purposes of license enforcement, compliance with the operating requirements specified in the license (under s. NR 666.102) shall be regarded as compliance with this section. However, evidence that compliance with those license conditions is insufficient to ensure compliance with this section may be information justifying modification or revocation and re-issuance of a license under s. NR 670.041.Wis. Admin. Code Department of Natural Resources NR 666.105
