The Oregon Department of Environmental Quality plans to hold a public hearing for proposed modifications to Heard Farms' water quality permit at 6 p.m. March 19 at Umpqua Community College's Science Building 10, 1140 Umpqua College Road, Roseburg.
Heard Farms proposed modifying its permit to add belt presses to remove water from biosolids. Heard Farms would remove ammonia from this water and use the recycled water and biosolids to irrigate fields at two locations.
Heard Farms' facility near Wilbur treats septage from residential septic tanks, sludge from sewage treatment plants, grease and milk processing waste and generates biosolids. Biosolids are then applied on DEQ-approved sites in the area as fertilizer to improve soil productivity. DEQ issued the facility's current 10-year Water Pollution Control Facilities permit Dec. 12, 2011.
The DEQ will review public comments before deciding whether to approve or deny the permit modification. The public comment period closes at 5 p.m. March 23 and the public can mail, fax or email comments to Tim McFetridge, DEQ Water Quality Program, 4026 Fairview Industrial Drive SE, Salem, OR 97302, 503-373-7977, email@example.com.
