Current through Register Vol. 48, No. 49, December 6, 2024

Section 611.591 - Violation of a State-Only MCL

This Section applies to State-only MCLs. If the result of analysis under Section 611.612 indicates that the level of any contaminant exceeds the State-only MCL, the CWS supplier must take certain actions:

a) Report to the Agency within seven days and initiate three additional analyses at the same sampling point within one month;

b) Notify the Agency and give public notice, as Subpart T specifies, if the average of four analyses exceeds the State-only MCL; and

c) After giving public notice, monitor at a frequency the Agency designates in a SEP. The supplier must continue monitoring until the results do not exceed the State-only MCL in two consecutive samples or until the effective date of a monitoring schedule the Board issues as a condition of a variance, adjusted standard, or enforcement action.
