Klickitat County Commissioners approved a 5% increase of monthly rates for customers of the Dallesport sewer plant.  Commissioners had left the record open for written comments last week, putting off a decision until Tuesday.  County officials said state law requires all utility service areas to be self-sustaining, and the County had been subsidizing the Dallesport wastewater tipping fees from the Roosevelt Regional Landfill.  But they say with County costs increasing, that cannot continue, and the rates must be brought in-line with other systems in the County.  With the rate increase, the monthly charge will now be $64.22.  The charge to connect into the system was increased by 3% to $4,602.68.  The resolution approved by Commissioners called for an annual review of the rates.  The panel heard testimony at their meeting last week about a number of issues including criticism of Klickitat PUD’s maintenance of the plant, but Commission members pointed out the subject at hand was the rate increase.  The County’s Public Works Department has indicated some of the equipment in the Dallesport treatment plant is at the end of its life and will need replacement that will need to be paid for.
