Cortina Integrated Waste Management Inc. (CIWM) has successfully negotiated a lease with the Cortina Band of Wintun Indians to design, construct and operate an integrated waste handling facility on 443 acres of the Cortina Rancheria in Colusa County California. The Class III, municipal waste landfill, is located approximately 85 miles north-east of San Francisco and will have an approximate disposal capacity of 16 million cubic yards of waste.
The landfill will encompass approximately 200 acres of the 443 acres leased and increase from an initial 300 tons per day (TPD) of disposal to 1500 TPD. The initial lease of 25 years, renewable for 25 years, also allows for future material recovery, composting and bio-remediation.
The U.S Department of the Interior, Bureau of Indian Affairs, issued a final approval of the lease in January 2007.
