ORDINANCE CONCERNING INDUSTRIAL PRETREATMENT PROGRAM City Manager Micheal Gleason introduced discussion of the City's industrial pretreatment program. Public Works Director Chris Andersen introduced James Ollerenshaw, Wastewater Treatment Plant Laboratory Supervisor. Mr. Ollerenshaw said the proposed ordinance will regulate industrial discharges into the treatment system to protect the workers, sewage system, and treatment plant from damage due to toxic or corrosive substances and to ensure that environmental damage is kept to a minimum. e Mr. Ollerenshaw said the pH and oil and grease discharge limits have been studied since 1984. The proposed changes raise the limit for pH discharge from 9.5 to 12.0, but no problems are anticipated from the increase, He said the City may reduce the limit if problems arise, pH discharges above 12.5 are identified as hazardous wastes in Federal regulations and are prohibited. He said animal and vegetable oil and grease are bio-degradable but hydrocarbon oil and grease are not bio-degradable. He said the proposed change will raise the total oil and grease limit to 300 milligrams per liter and create a limit of 100 milligrams per liter for hydrocarbon oil and grease.

Answering questions from Mayor Obie and Ms, Bascom, Mr, Gleason said the proposed changes have been in effect for some time and the City will work with the affected industries. The changes will not decrease the water quality from e MINUTES--Eugene City Council September 17, 1986 Page 4
