Sec. 60-181. - Publication of industrial users in significant noncompliance.
The director shall publish annually, in a newspaper of general circulation that provides meaningful public notice within the jurisdictions served by the city's POTW, a list of the industrial users which, during the previous 12 months, were in significant noncompliance with applicable pretreatment standards and requirements. The term significant noncompliance shall mean one or more of the following:
(1) Chronic violations of wastewater discharge limits, defined here as those in which 66 percent 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;
(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 multiplied by the applicable TRC. The TRC for BOD, TSS, fats, oils and grease is 1.4. For all other parameters except pH, the criteria is 1.2;
(3) Any other discharge violation of a pretreatment standard or requirement as defined by 40 CFR 403.31(1) (daily maximum, long-term average, instantaneous limit, or narrative standard) that the director believes has caused, or has the potential to cause, alone or in combination with other discharges, interference or pass through, or to endanger the health or welfare of city personnel or the general public;
(4) Any discharge of pollutants that has caused imminent endangerment to the public or to the environment, or has resulted in the city's exercise of 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 a wastewater discharge permit or an 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, 90-day compliance reports, periodic self-monitoring reports, and reports on compliance with compliance schedules;
(7) Failure to accurately report noncompliance;
(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.
