Section 252:628-3-8 - IPR benchmarks for Constituents of Emerging Concern

(a)Effluent monitoring requirements. IPR Source Water discharges shall be monitored quarterly for a DEQ-approved list of CEC surrogates. In addition, IPR Source Water discharges shall be monitored for a DEQ-approved list of CECs every five (5) years upon permit renewal, in accordance with permit application requirements. IPR Sample plans are described in Subchapter 11 of this Chapter.

(b)Corrective actions. Should effluent monitoring conducted in accordance with paragraph (a) of this Section demonstrate that the IPR SWTP is not achieving overall CEC reductions, show an anomalous spike, or should IPR receiving waterbody monitoring indicate a violation of an action level established in accordance with Subchapter 11 of this Chapter, the permittee shall notify DEQ within 24 hours and initiate corrective action if directed by DEQ. A written report describing the reason(s) for the failure to achieve overall CEC reductions or for the violation(s) of the action levels and the proposed corrective action(s) shall be submitted to DEQ within five (5) days. Corrective actions to control CECs shall include but not be limited to:

(1) Evaluating the treatment system effectiveness, operations and maintenance, and making alterations as necessary;

(2) Increasing the effluent monitoring frequency to better characterize the pattern and extent of variation for a given CEC;

(3) Evaluating the collection system for new or increased sources and taking appropriate steps to reduce these sources; and

(4) Implementing additional source controls such as Best Management Practices (BMPs), community disposal centers for pharmaceutical and personal care products (PPCPs), and/or public outreach and awareness programs.
