Washington County Water and Sewer Department Director George Gross proposed to the County Commissioners at a public hearing Tuesday that the rate for treating emulsified oily waste at the industrial pretreatment plant be raised from about 7 cents to about 20 cents a gallon.
Mack Trucks is the pretreatment plant's only customer for that kind of waste, Gross said.
About 1.6 million gallons of emulsified oily waste passes through the pretreatment plant a year, at an operating cost of about $318,000, accounting for about 10 percent of the plant's business, he said.
Last year the pretreatment plant posted a $42,000 profit on emulsified oily waste treatment but that money doesn't represent a profit because some major maintenance projects must be done, Gross said.
