- (b) For systems conducting monitoring at a frequency greater than annually, the department shall determine compliance with the MCL for asbestos by analyzing a running annual average at each sampling point.
- (c) If the average at any sample point is greater than the MCL, then the system shall be out of compliance.
- (d) If any one sample in (c), above, would cause the running annual average to exceed the MCL, the system shall be out of compliance.
