The city shall publish annually, in a newspaper(s) of general circulation that provides meaningful public notice within the jurisdiction(s) served by the POTW, a list of the users which, at any time during the previous 12 months, were in significant noncompliance with applicable pretreatment standards and requirements. For the purposes of this provision, an industrial user is in significant noncompliance if its violation meets one or more of the following criteria:
(A) Chronic violations of wastewater discharge limits, defined here as those in which 66% or more of wastewater measurements taken for the same pollutant parameter during a six- month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits, as defined by 40 CFR 403.3(1);
(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 40 CFR 403.3(1) multiplied by the TRC [TRC=1.4 for BOD, TSS, fats, oils and grease, and 1.2 for all other pollutants except pH];
(C) Any other discharge violation of a pretreatment standard or requirement as defined by 40 CFR 403.3(1) (daily maximum, longer-term average, instantaneous limit, or narrative Standard) that the POTW 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 have caused imminent endangerment to the public or to the environment, or have resulted in the city's 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 a wastewater discharge permit or enforcement order for starting construction, completing construction, or attaining final compliance;
(F) Failure to provide within 30 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 or group of violations, which may include a violation of best management practices, which the POTW determines will adversely affect the operation or implementation of the local pretreatment program.
