Effluent monitoring frequency when permit limitations are required
Cite as Okla. Admin. Code § 252:690-3-89
[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.
