Coal—850 parts per million dry volume3-run average (1 hour minimum sample time per run)Performance test (Method 6 or 6c at 40 CFR part 60, appendix A-4). Fugitive ashVisible emissions for no more than 5 percent of the hourly observation periodVisible emissions for no more than 5 percent of the hourly observation periodThree 1-hour observation periodsVisible emission test (Method 22 at 40 CFR part 60, appendix A-7).

1 The date specified in the state plan can be no later than 3 years after the effective date of approval of a revised state plan or February 7, 2018.

2 All emission limitations (except for opacity) are measured at 7 percent oxygen, dry basis at standard conditions. For dioxins/furans, you must meet either the total mass basis limit or the toxic equivalency basis limit.

3 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 §§ 60.2710 and 60.2730. As prescribed in § 60.2710(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.
