South Dakota Acceptance Letter (Not Approved) »

South Dakota Visible Emissions / Opacity Standard

The opacity limit for South Dakota is 20% opacity, flat statewide (both the visible-emissions chapter and the regulated-pollutant chapter use 20%), as established under ARSD 74:36:12:01 (control of visible emissions); 74:36:06:01 (sources not otherwise limited).

Compliance is demonstrated via EPA Method 9 (40 CFR Part 60, Appendix A); compliance testing per ARSD 74:36:11 (Performance Testing).

Averaging period: Not explicitly specified in available rule text; standard applied per Method 9 (6-minute average)

South Dakota's visible emissions chapter (ARSD 74:36:12) establishes a 20% opacity limit that generally applies to all sources. EPA's SIP review documentation explicitly confirmed 'a 20% opacity limit that generally applies to all sources' in ARSD 74:36:12. Source-specific opacity standards may also be applied through permits. An exception to the opacity standard was the subject of a 2015 EPA SSM SIP Call.
