Abstract: The
Disinfectants/Disinfection Byproducts, Chemical and Radionuclides
Rules ICR examines public water system, primacy agency and EPA
burden and costs for recordkeeping and reporting requirements in
support of the chemical drinking water regulations. These
recordkeeping and reporting requirements are mandatory for
compliance with 40 CFR parts 141 and 142. The following chemical
regulations are included: Stage 1 Disinfectants and Disinfection
Byproducts Rule (Stage 1 DBPR), Stage 2 Disinfectants and
Disinfection Byproducts Rule (Stage 2 DBPR), Chemical Phase Rules
(Phases II/IIB/V), 1976 Radionuclides Rule and 2000 Radionuclides
Rule, Total Trihalomethanes (TTHM) Rule, Disinfectant Residual
Monitoring and Associated Activities under the Surface Water
Treatment Rule, Arsenic Rule, Lead and Copper Rule (LCR) and
revisions.
The decrease in burden is
primarily attributable to the use of updated system inventories and
entry points to calculate monitoring costs. Also, there was a
decrease in burden due to the completion of initial monitoring
under the Arsenic Rule and the completion of startup associated
with the Lead and Copper Rule Short Term Revisions. The changes due
to Agency Discretion listed on the individual ICs stem from the
consolidation of three ICs into two. In the previous ICR (for a
Final Rule), one IC was left unaltered which covered the existing
requirements. The second two ICs detailed the burden on private
sector and state entities due to the new rule only. This renewal
ICR has thus consolidated the burden for private and state entities
into their respective ICs, and eliminated the now-unnecessary third
one. While the deletion of the IC is characterized as a program
change, this is only due to the constraints of ROCIS, and there was
no program change in reality.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
