KINGMAN, Ariz. – The Bureau of Land Management’s (BLM) Kingman Field Office invites the public to provide input on a Comprehensive Environmental Response Compensation and Liability Act (CERCLA) remediation project at the abandoned COD Mine and Mill site, located on BLM-managed public land in the Cerbat Mountains north of Kingman, in Mohave County.  

The mine opened in 1878 and produced silver, lead, zinc and gold until it permanently closed in 1984. Lead, arsenic and thallium have since been found in tailings, waste rock dumps, surrounding soils and drainage areas, at levels that exceed the Arizona Department of Environmental Quality’s non-residential soil standards. No groundwater contamination has been detected.

In 2017, BLM contracted Phoenix-based Terranext, an environmental engineering firm, to evaluate the site. Terranext has completed a Draft Final Engineering Evaluation/Cost Analysis (EECA) to determine the best way to remediate the contamination at the site.

BLM will hold a public open house from 1-4 p.m. on Aug. 23, 2019, to present the EECA. During the meeting, BLM and Terranext staff will be available to answer questions, review maps, and receive public comments about the EECA. The open house will be held at:

Mohave Community College Kingman Campus 1971 Jagerson Avenue, Room 113 Kingman, AZ 86409

A public comment period will be open for a period of 30 calendar days from Aug. 19 to Sept. 18, 2019. Copies of the draft EECA will be available for public review and commenting at the BLM’s Kingman Field Office, 2755 Mission Boulevard, Kingman, AZ 86401, or online through the ePlanning website at Comments may be submitted through ePlanning or by mail to the Kingman Field Office.
