People who live and work near a Tualatin composting facility want the state Department of Environmental Quality to reduce odors emanating from the plant.
The Oregonian newspaper reports the DEQ held a public hearing Wednesday on a draft composting permit for Grimm's Fuel Company.
Dozens have complained about shutting windows and staying indoors because of the composting smell. Residents at the hearing were fearful that the permit would eventually allow the facility to compost meat, dairy products and certain dead animals.
Grimm's has been composting mostly yard debris and clippings since 1980, but is interested in composting residential food waste if a curbside collection program starts nearby.
DEQ is accepting written comment until Nov. 6, and the agency expects to respond to comments and issue a decision in December.
