PAYETTE COUNTY â Hardin Sanitation customers who may have gotten comfortable with their trash collection bill may be sad to learn that their rates will be going up 3.5% later this year. The rate increase was approved by the Payette County Board of Commissioners on May 24. In an email to the newspaper on Monday, site manager Mark Fulweiler said Hardin had put off raising the rate to be fair to customers, but that operating costs forced their hand this year. âHardin Sanitation has not requested the contractual price increase for the past three years, even though the Consumer Price Index (CPI) has risen 5.2%,â said Fulweiler. âLooking at the local environment, we thought asking for a 3.5% increase was fair.â
