Violation of a State-Only MCL
Section 611
Section 611.591Â 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)Â Â Â Â Â Â Â Â Report to the Agency within seven days and initiate three
additional analyses at the same sampling point within one month;
b)Â Â Â Â Â Â Â Â Notify the Agency and give public notice, as Subpart T
specifies, if the average of four analyses exceeds the State-only MCL; and
c)Â Â Â Â Â Â Â Â 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.
BOARD NOTE:Â
This is an additional State requirement.
