[REVOKED] (a) When monitoring is required in a permit, the following are the minimum monitoring frequencies for parameters during the initial permit cycle: (1) once a week for temperature limits. (2) twice a month for aquatic toxicity criterion-based limits, human health and raw water criterion-based limits, and agriculture criterion-based limits. (3) for bacteriological limitations: (A) twice a week during May 1 through September 30 to protect the PBCR beneficial use, (B) once a week to protect the SBCR beneficial use, if the receiving stream is impaired for bacteria, and (C) once a week for total coliform limits, unless bacteriological limitations for PBCR are also established in the permit, in which case the minimum total coliform monitoring frequency will be once a week for the period October 1 through April 30 only to protect the PPWS beneficial use. (b) DEQ may increase the monitoring frequencies listed in (a)(1) and (2) of this Section for a period not to exceed one (1) year during the initial permit cycle for the purpose of establishing the pattern and extent of variation for a given pollutant.
