US EPA releases proposed cleanup plan for Casmalia Resources Superfund Site in California

The U.S. Environmental Protection Agency is proposing a comprehensive cleanup plan to address contaminated soil and groundwater at the Casmalia Resources Superfund Site in Santa Barbara County, California.

The former hazardous waste treatment, storage, and disposal facility closed in 1989. 

The site was listed on the National Priorities List in 2001 after years of operational problems, releases of waste materials, abandonment by the original operator, and concerns raised by local communities.

the U.S. Environmental Protection Agency (EPA) is proposing a comprehensive cleanup plan to address contaminated soil and groundwater at the Casmalia Resources Superfund Site in Santa Barbara County, Calif. The former hazardous waste treatment, storage, and disposal facility closed in 1989. The site was listed on the National Priorities List in 2001 after years of operational problems, releases of waste materials, abandonment by the original operator, and concerns raised by local communities.EPA's recommended cleanup plan includes: contaminated hotspot removal, engineered capping systems, groundwater collection and treatment systems, natural breakdown of groundwater contaminants at some locations, long-term surface water management, source reduction, land use controls, and ongoing monitoring and maintenance to ensure onsite containment. Construction of the proposed cleanup plan is estimated to take five years and cost approximately $60 million. Annual operations and maintenance costs are estimated at $4.1 million per year.

EPA welcomes public comments on the plan from Wednesday, November 22, 2017, to Monday, January 22, 2018.  EPA will host a public meeting to discuss the proposed plan from 6 to 8 p.m. on Wednesday, December 6, 2017, at Orcutt Academy Charter School (formerly Winifred Wollam Elementary School), at 3491 Point Sal Road in Casmalia, Calif.  Spanish interpretation services will be provided.
