Appendix - Table 7 to Subpart CCCC of Part 60—Emission Limitations for Waste-Burning Kilns That Commenced Construction After June 4, 2010, or Reconstruction or Modification After August 7, 2013
For the air pollutant You must meet this emission limitation 1 Using this averaging time 2 And determining compliance using this method 2, 3
Cadmium0.0014 milligrams per dry standard cubic meter3-run average (collect a minimum volume of 4 dry standard cubic meters per run)Performance test (Method 29 at 40 CFR part 60, appendix A-8). Use ICPMS for the analytical finish.
Carbon monoxide90 (long kilns)/190 (preheater/precalciner) parts per million dry volume3-run average (1 hour minimum sample time per run)Performance test (Method 10 at 40 CFR part 60, appendix A-4).
Dioxins/furans (total mass basis)0.51 nanograms per dry standard cubic meter3-run average (collect a minimum volume of 4 dry standard cubic meters per run)Performance test (Method 23 at 40 CFR part 60, appendix A-7).
Dioxins/furans (toxic equivalency basis)0.075 nanograms per dry standard cubic meter3-run average (collect a minimum volume of 4 dry standard cubic meters)Performance test (Method 23 at 40 CFR part 60, appendix A-7).
Hydrogen chloride3.0 parts per million dry volume3-run average (1 hour minimum sample time per run) or 30-day rolling average if HCl CEMS is being usedIf a wet scrubber or dry scrubber is used, performance test (Method 321 at 40 CFR part 63, appendix A). If a wet scrubber or dry scrubber is not used, HCl CEMS as specified in § 60.2145(j).
Lead0.014 milligrams per dry standard cubic meter3-run average (collect a minimum volume of 4 dry standard cubic meters)Performance test (Method 29 at 40 CFR part 60, appendix A-8). Use ICPMS for the analytical finish.
Mercury0.0037 milligrams per dry standard cubic meter. Or 21 pounds/million tons of clinker 330-day rolling averageMercury CEMS or integrated sorbent trap monitoring system (performance specification 12A or 12B, respectively, of appendix B and procedure 5 of appendix F of this part), as specified in § 60.2145(j).
Nitrogen oxides200 parts per million dry volume30-day rolling averageNitrogen oxides CEMS (performance specification 2 of appendix B and procedure 1 of appendix F of this part).
Particulate matter (filterable)4.9 milligrams per dry standard cubic meter3-run average (collect a minimum volume of 2 dry standard cubic meters)Performance test (Method 5 or 29 at 40 CFR part 60, appendix A-3 or appendix-8).
Sulfur dioxide28 parts per million dry volume30-day rolling averageSulfur dioxide CEMS (performance specification 2 of appendix B and procedure 1 of appendix F of this part).

1 All emission limitations are measured at 7 percent oxygen (except for CEMS and integrated sorbent trap monitoring system data during startup and shutdown), dry basis at standard conditions. For dioxins/furans, you must meet either the Total Mass Basis limit or the toxic equivalency basis limit.

2 In lieu of performance testing, you may use a CEMS or, for mercury, an integrated sorbent trap monitoring system, to demonstrate initial and continuing compliance with an emissions limit, as long as you comply with the CEMS or integrated sorbent trap monitoring system requirements applicable to the specific pollutant in §§ 60.2145 and 60.2165. As prescribed in § 60.2145(u), if you use a CEMS or integrated sorbent trap monitoring system to demonstrate compliance with an emissions limit, your averaging time is a 30-day rolling average of 1-hour arithmetic average emission concentrations.

3 Alkali bypass and in-line coal mill stacks are subject to performance testing only, as specified in § 60.2145(y)(3). They are not subject to the CEMS, integrated sorbent trap monitoring system, or CPMS requirements that otherwise may apply to the main kiln exhaust.
