he Stage 2 Disinfection Byproducts Rule (Stage 2 DBPR) was
released by the EPA in January 2006. The intent of this Rule
is to supplement the existing regulations by basing monitoring
requirements on population and source water type only. Stage 2
also requires systems to meet the existing MCL requirements for
TTHMs and HAA5s at each specific location, rather than allowing
systems to continue averaging all location results together. Systems
were required to complete an Initial Distribution System Evaluation
(IDSE) to locate sites with the highest TTHM and HAA5 levels,
unless they obtained 40/30 Certification or a Very Small System
Waiver in lieu of the IDSE. Once this was completed, systems were
further required to complete a Compliance Monitoring Plan (CMP)
to indicate which sites they will sample under Stage 2. Public
Water Supply Section (PWS Section) staff developed two templates
of the CMP form; the standard form is used by systems treating
surface water, and the short form is for all purchase systems and
groundwater-only systems on Schedules 3 & 4. PWS Section set
a due date for the CMPs for the Schedule 3 & 4 systems as July 1,
2013, in an effort to allow the time needed to review the plans prior
to the compliance monitoring start date of October 1, 2013.
