Friends of Outlet Creek formed in 2011 in opposition to Grist Creek Aggregates’ efforts to expand industrial development at its Longvale site. This site is precariously misplaced on the banks and in the floodplain of Outlet Creek. In 2011 Grist Creek Aggregates applied for development review for a new asphalt and concrete batch plant. They were advised by County agencies to remove the asphalt plant from the application because of issues of air pollution and hazardous materials that would require an EIR. Former County Air District official, Chris Brown, said, “It is my feeling that all asphalt plants will need an EIR because you have storage of oils, air toxic emissions and odor issues that need to be addressed.” GCA dropped the asphalt plant off the application, but continued to pursue the concrete batch plant. In 2013 after much public comment against the concrete batch plant by county, state and federal agencies, Grist Creek Aggregates withdrew their concrete batch plant application as well.
In March of 2015, the Mendocino County Board of Supervisors bypassed development review for a new asphalt plant at the site. They voted five to zero in favor of invoking their power of “original jurisdiction” to circumvent the normal planning process. Friends of Outlet Creek filed a lawsuit against the County for noncompliance with the California Environmental Quality Act (CEQA) which requires new development to undergo environmental review. In June, the County quietly rescinded their resolution of “original jurisdiction” claiming the asphalt plant could go forward without it. That same month Mendocino County Air Quality Management District approved a permit for construction of a new asphalt plant at the site allowing up to 500,000 thousand tons of asphalt production annually. Friends of Outlet Creek has filed a second lawsuit against the Air District for noncompliance with CEQA.
