The term significant noncompliance shall be applicable to all significant industrial users (or any industrial user that violates divisions (C), (D) or (H) below) and shall mean:
(A) CHRONIC VIOLATIONS OF WASTEWATER DISCHARGE LIMITS, defined here as those in which 66% or more of measurements taken for the same pollutant parameter taken during a six-month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits as defined in §§ 53.015 through 53.022 of this chapter;
(B) TECHNICAL REVIEW CRITERIA (TRC) VIOLATIONS, defined here as those in which 33% or more of wastewater measurements taken for each pollutant parameter during a six-month period equals or exceeds the product of the numeric pretreatment standard or requirement including instantaneous limits, as defined by § 53.018 of this chapter multiplied by the applicable criteria (1.4 for BOD, TSS, fats, oils and grease, and 1.2 for all other pollutants except pH);
(C) Any other violation of a pretreatment standard or requirement defined by §§
53.015 through 53.022
of this chapter (daily maximum, long-term average, instantaneous limit, or narrative standard) that the IPD determines has caused, alone or in combination with other discharges, interference or pass through, including endangering the health of POTW personnel or the general public;
(D) Any discharge of pollutants that has caused imminent endangerment to the public or to the environment, or has resulted in the IPD exercise of its emergency authority to halt or prevent such a discharge;
(E) Failure to meet, within 90 days of the scheduled date, a compliance schedule milestone contained in an individual wastewater discharge permit, general permit, or enforcement order for starting construction, completing construction, or attaining final compliance;
(F) Failure to provide within 45 days after the due date, any required reports, including baseline monitoring reports, reports on compliance with categorical pretreatment standard deadlines, periodic self-monitoring reports, and reports on compliance with compliance schedules;
(G) Failure to accurately report noncompliance; or
(H) Any other violation(s), which may include a violation of best management practices that the IPD determines will adversely affect the operation or implementation of the local pretreatment program.
