NR 666.104(6)(6)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 subs. (2), (3) and (4) by monitoring in the by-pass duct if both of the following conditions are met:
NR 666.104(6)(a)(a) 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.
NR 666.104(6)(b)(b) The by-pass duct diverts a minimum of 10% of kiln off-gas into the duct.
NR 666.104(7)(7)Use of emissions test data to demonstrate compliance and establish operating limits. Compliance with this section shall 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 shall be obtained during the time that DRE testing, and where applicable, CDD/CDF testing under sub. (5) and comprehensive organic emissions testing under sub. (6) is conducted.
NR 666.104(8)(8)Enforcement. 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.
NR 666.104 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06; corrections in (1) (b), (2) (b), (3) (c), (5) (b) to (d) made under s. 13.92 (4) (b) 7., Stats., Register March 2013 No. 687.
NR 666.105NR 666.105Standards to control particulate matter.
NR 666.105(1)(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.
NR 666.105(2)(2)An owner or operator meeting s. NR 666.109 (2) for the low risk waste exemption is exempt from the particulate matter standard.
NR 666.105(3)(3)Oxygen correction.
NR 666.105(3)(a)(a) Measured pollutant levels shall be corrected for the amount of oxygen in the stack gas according to the formula:
-
×
=
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.
NR 666.105(3)(b)(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.
NR 666.105(3)(c)(c) Compliance with all emission standards provided by this subchapter shall be based on correcting to 7% oxygen using this procedure.
NR 666.105(4)(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.
NR 666.105 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06; correction in (1) made under s. 13.92 (4) (b) 7., Stats., Register March 2013 No. 687.
NR 666.106NR 666.106Standards to control metals emissions.
NR 666.106(1)(1)General. The owner or operator shall comply with the metals standards provided by subs. (2), (3), (4), (5), or (6) for each metal listed in sub. (2) that is present in the hazardous waste at detectable levels by using appropriate analytical procedures.
NR 666.106(2)(2)Tier I feed rate screening limits. Feed rate screening limits for metals are specified in ch. NR 666 Appendix I as a function of terrain-adjusted effective stack height and terrain and land use in the vicinity of the facility. Criteria for facilities that are not eligible to comply with the screening limits are provided in par. (g).
NR 666.106(2)(a)(a) Noncarcinogenic metals. The feed rates of antimony, barium, lead, mercury, thallium and silver in all feed streams, including hazardous waste, fuels, and industrial furnace feed stocks may not exceed the screening limits specified in ch. NR 666 Appendix I.
NR 666.106(2)(a)1.1. The feed rate screening limits for antimony, barium, mercury, thallium and silver are based on either of the following:
NR 666.106(2)(a)1.a.a. An hourly rolling average as defined in s. NR 666.102 (5) (f) 1. b.
NR 666.106(2)(a)1.b.b. An instantaneous limit not to be exceeded at any time.
NR 666.106(2)(a)2.2. The feed rate screening limit for lead is based on one of the following:
NR 666.106(2)(a)2.a.a. An hourly rolling average as defined in s. NR 666.102 (5) (f) 1. b.
NR 666.106(2)(a)2.b.b. An averaging period of 2 to 24 hours as defined in s. NR 666.102 (5) (f) 2. with an instantaneous feed rate limit not to exceed 10 times the feed rate that would be allowed on an hourly rolling average basis.
NR 666.106(2)(a)2.c.c. An instantaneous limit not to be exceeded at any time.
