Cedar Grove Composting: Permitting and Regulatory Compliance

We have represented Cedar Grove Composting for decades and have helped it grow into one of the largest composters in the United States. We have assisted in the expansion of Cedar Grove’s facilities, handling its regulatory work before State and regional air agencies, and permitting work with the U.S. Army Corps of Engineers and the Washington State Department of Ecology. We also have helped it respond to complaints of nuisance odors or stormwater issues associated with its operations.

We recently completed negotiation of an Agreed Order and odor mitigation plan under which Cedar Grove agreed to voluntarily undertake capital improvements and operational modifications in order to assure that its operations do not impact the neighboring communities in Everett, Marysville, and Maple Valley. This work involved the negotiation of an Agreed Order with the Puget Sound Clean Air Agency under which the Agency acknowledged Cedar Grove’s voluntary mitigation large capital investment in odor control, which has addressed the Agency’s concerns and responded to the needs of the neighboring communities.

Cedar Grove is the largest private composter in the U.S. The company is building commercial methane digesters to capture methane and generate electricity from biomass to sell back to the grid.
