Rule 3745-81-69 | Reporting and Recordkeeping Requirements for LT2 only.
(A) Reporting requirements.
(1) Systems shall report sampling schedules in accordance with paragraph (I) of rule 3745-81-65 of the Administrative Code and source water monitoring results in accordance with paragraph (A) of rule 3745-81-66 of the Administrative Code unless they notify the director that they will not conduct source water monitoring due to meeting the criteria of paragraph (D) of rule 3745-81-65 of the Administrative Code.
(2) Systems shall report their Cryptosporidium bin classification as described in paragraphs (A) to (D) of rule 3745-81-67 of the Administrative Code.
(3) Systems shall report disinfection profiles and benchmarks to the director as described in paragraph (E) of rule 3745-81-72 of the Administrative Code prior to making a significant change in disinfection practice.
(4) Systems shall report to the director in accordance with the following table for any microbial toolbox options used to comply with treatment requirements in accordance with paragraph (E) of rule 3745-81-67 of the Administrative Code. Alternatively, the director may approve a system to certify operation within required parameters for treatment credit rather than reporting monthly operational data for toolbox options.
