The director shall publish annually, in a newspaper that provides meaningful public notice within the jurisdictions served by the city, a list of the users which, at any time during the previous 12 months, were in SNC with applicable pretreatment standards and requirements. A SIU (or any user which violates items (3), (4), or (8) of this section) is in significant noncompliance if its violation meets one or more of the following criteria:
(1) Chronic violations of wastewater discharge limits, defined here as those in which 66 percent or more of all the 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 section 47-188 of this article;
(2) Technical review criteria (TRC) violations, defined here as those in which 33 percent 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 section 47-188 of this article multiplied by the applicable criteria (1.4 for BOD, TSS, fats, oils and grease, and 1.2 for all other pollutants except pH, TRC criteria do not apply to pH);
(3) Any other violation of a pretreatment standard or requirement as defined by section 47-188 of this article (daily maximum, long-term average, instantaneous limit, or narrative standard) that the director 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;
(4) Any discharge of a pollutant that has caused imminent endangerment to the public or to the environment, or has resulted in the director's exercise of its emergency authority to halt or prevent such a discharge;
(5) Failure to meet, within 90 days of the scheduled date, a compliance schedule milestone contained in an individual wastewater discharge permit or a general permit or enforcement order for starting construction, completing construction, or attaining final compliance;
(6) 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;
(7) Failure to accurately report noncompliance; or
(8) Any other violation(s), which may include a violation of best management practices, which the director determines will adversely affect the operation or implementation of the local pretreatment program.
