Details: Increase DBP monitoring to quarterly since Row Riverís August DBP sample exceeded the MCL for HAA5s. This exceedance isnít an MCL violation (which is long-run annual average based), though it triggers increased monitoring frequency.

The rule language follows for reference from 333-061-0036-(4)(e) Increased Monitoring:
(A) At water systems where annual or less frequent monitoring is required according to subsections (4)(c) or (4)(d) of this rule, monitoring must be increased to dual sample sets collected every 90 days at all locations if a TTHM or HAA5 sample exceeds the MCL at any location.
(B) At water systems where increased monitoring is conducted according to paragraph (4)(e)(A) of this rule, samples must be collected at the
monitoring locations specified in the monitoring plan developed according to paragraph (4)(c)(B) of this rule.
(C) Monitoring may be returned to routine if at least four consecutive quarters of increased monitoring has been conducted and the LRAA for
every monitoring location is less than or equal to 0.060 mg/L for TTHM and 0.045 mg/L for HAA5.
