Waste hauler fees are changing and increasing. The switch begins a dual fee structure at McMinnville Wastewater Treatment Plant for businesses inside Warren County and those that are not.Affected by the fees are companies that deal with cleaning septic tanks and systems, those offering portable toilets, and package plant waste. Those outside Warren County will be paying a higher fee than those inside.Currently, the city charges a set fee for the type of vehicle and number of gallons a waste hauler wants the city’s plant to take, regardless of where the business resides.Fee schedule:• Class A — 0 to 100 gallons is $6.50, • Class B — 501 to 1,000 gallons is $13• Class C — 1,001 to 2,000 gallons is $26• Class D — 2,001 to 3,000 gallons is $39• Class E — Over 3,000 gallons is $52; • Class E — Over 4,000 gallons is $10 per 1,000 gallonsHowever, surrounding counties are charging far more in comparison.
