   Construction of any approved facilities shall be completed within six months of notice to provide protection.

The notification shall include location of discharge, date and time thereof, type of waste, concentration and volume, and corrective actions. Any discharger who discharges slugs or accidental discharge of prohibited materials shall be liable for any expense, loss or damage to the POTW, in addition to the amount of any fines imposed on the City on account thereof under state and federal law.

   (d)    Procedures to prevent adverse impact from accidental spills, including inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site run-off, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents), and /or measures equipment for emergency response;

   Signs shall be permanently posted in conspicuous places on the discharger's premises, advising employees whom to call in the event of a slug or accidental discharge. Employees shall instruct all employees, who may cause or discover such a discharge, with respect to emergency notification procedure.

   Each SIU shall notify the City of any significant changes to their operations that might alter the nature, quality, or volume of its wastewater, at least 30 days prior to that change.
