9) Did any violation cause imminent endangerment to human health / welfare or to the
environment or has resulted in the POTW's exercise of its emergency authority to halt

10) If the answer to any of these questions is yes, the SIU is in Signficant Non -Compliance (SNC) for this parameter.
They must be listed on the Significant Non -Compliance Report (SNCR) form in the Pretreatment Annual Report
(PAR), described in the PAR narrative (including parameter, period, and POTW actions), and the POTW must
take adequate enforcement as outlined in its Enforcement Responce Plan (ERP).
Is the SIU in SNC for this six month period? CIRCLE ONE: YES NO
Was the SIU in SNC for THE SAME PARAMETER in the previous six month compliance
eu riod? CIRCLE ONE: YES NO
If YES to EITHER question, DESCRIBE IN NARRATIVE.
Please note if SIU was in SNC for the previous six month compliance period and is also in SNC for this six month
compliance period, escalated enforcement actions must be taken as soon as possible, preferably before the
end of the second consecutive period. Failure to take the action within 2 months after the end of the second
consecutive period will subject the POTW to enforcement by the Division. The options are:
Consent Order with Enforceable schedule;
Administrative Order with Enforceable schedule;
Formal notice to comply issued, or
