# §52.794. Source surveillance.

- (a) The requirements of 51.212 of this chapter are not met by the phrase “for more than a cumulative total of 15 minutes in a 24-hour period” contained in [section 1](/cfr/40/1.md) of APC-3 of the Indiana Air Pollution Control Regulations.
- (b) [Reserved]
- (c) 325 IAC 5-1 (October 6, 1980, submittal—[§ 52.770(c)(53)](/cfr/40/52.770.md?p=c-53)) is disapproved for the Lake County sources specifically listed in Table 2 of 325 IAC 6-1-10.2 ([§ 52.770(c)(57)](/cfr/40/52.770.md?p=c-57)); for pushing and quenching sources throughout the State (August 27, 1981, 325 IAC 11-3-2 (g) and (h)—[§ 52.770(c)(42)](/cfr/40/52.770.md?p=c-42)); and for coke oven doors in Lake and Marion Counties (325 IAC 11-3-2(f)—[§ 52.770(c)(42)](/cfr/40/52.770.md?p=c-42)). Applicability of this regulation to these sources is being disapproved because 325 IAC 5-1 does not meet the enforceability requirements of [§ 51.22](/cfr/40/51.22.md) as it applies to these sources. Opacity limits in 325 IAC 6-1-10.2 and certain opacity limits in 325 IAC 11-3 supersede those in 325 IAC 5-1, and USEPA has previously disapproved these superseding regulations (§ [52.776 (j)](/cfr/40/52.776.md?p=j), [(g)](/cfr/40/52.776.md?p=g), and [(f)](/cfr/40/52.776.md?p=f), respectively).
