RESET Information from June 21st DMAC webinar:
The regulatory reference is under the Coliform Treatment Technique triggers and assessment requirements – 141.589 (a)(2)(ii). This section talks about the two ways a Level 2 can be triggered either through the E.coli MCL for by having a second Level 1 trigger w/in a rolling 12 months UNLESS the state has determined a likely reason for TC+ sample and the system has corrected the problem.
Alaska got the term “reset” from the RTCR Assessment and Corrective Actions Guidance Manual – Appendix B which is an example of a Level 1 Assessment. At the bottom of this Assessment (page B-3 or PDF page 124) in the portion reserved for State (item #4) it has the question “was a reset requested and/or granted?”
When Alaska was putting their assessment form together they started with this document and emailed EPA Region 10 to ask what a “reset” was and here was the response:
EPA response: The “reset” refers to the discretion given to States in 141.859(a)(2)(ii) in determining whether a Level 2 assessment has been triggered after a second Level 1 trigger has been exceeded within a rolling 12-month period. If the first Level 1 trigger has been determined by the State to be caused by the presence of total coliforms and the system has corrected the problem during the assessment, then the State has the discretion to not count that first Level 1 trigger towards a Level 2 assessment. The second Level 1 trigger therefore does not trigger a Level 2 assessment and remains as a Level 1 assessment. It also “resets” to being the first Level 1 assessment in terms of determining a Level 2 assessment for the next round.
