If your system is considering a significant change to its disinfection practice, your system must calculate a disinfection benchmark(s) as described in §§ 141.543 and 141.544 and provide the benchmark(s) to your State.

Your system must submit the following information to the State as part of the consultation and approval process:
(a) A description of the proposed change;
(b) The disinfection profile for Giardia lamblia (and, if necessary, viruses) and disinfection benchmark;
(c) An analysis of how the proposed change will affect the current levels of disinfection; and
(d) Any additional information requested by the State.
