PALM SPRINGS, Calif. — The Bureau of Land Management Palm Springs-South Coast Field Office has approved the Slaughterhouse Canyon proposal for the competitive sale of mineral materials on a 119-acre site of public subsurface estate about four miles north of Lakeside in San Diego County.

The mineral sale will be offered in response to a request from the surface estate owner, Hanson Aggregates Pacific Southwest LLC, who has operated an aggregate mining and processing facility on adjacent land to the site since the mid-1950s. The BLM analyzed the environmental effects of the proposed sale of mineral materials and determined the proposed actions and alternatives did not have a significant effect on the environment.

“The BLM decided to approve the mineral sale after completing an environmental analysis and 30-day public review of the analysis,” said Tim Gilloon, Palm Springs-South Coast field manager. “If the BLM issues a mineral materials contract, future mining and reclamation plans will be required and analyzed under the National Environmental Policy Act and California Environmental Quality Act.”
