All parameters shall be monitored semi-annually with a grab sample of the effluent.  Results will be reported annually on a Discharge Monitoring Report (DMR).  

As is found in the existing permit, several conditions for storm event sampling records, SWPPP certification form, and SWPPP development, components, controls, implementation, and amendments are being added to the proposed permit. 

Two special conditions are being added.  One condition addresses the submittal of a Form 2F Application within 180 days after discharge.  The application is being required as the facility failed to test for all required pollutants as part of their re-issuance application.   The second special condition requires the facility to submit an updated SWPPP within sixty (60) days after permit issuance.
