Environmental Remediation Public Meeting: Baker Beach Disturbed Areas 1 and 2a
The California Department of Toxic Substances Control (DTSC) and the Presidio Trust announce the availability of two Draft FS/RAPs which recommend cleanup for Baker Beach Disturbed Areas (BBDAs) 1A and 2 in the Presidio. A California Environmental Quality Act (CEQA) Draft Negative Declaration for the cleanup project has also been prepared (see below)
A public meeting will be held to present the cleanup plans proposed by the Draft FS/RAPs and record oral public comments. It will take place on Wednesday, January 9, 2013 at 7 pm, at the Golden Gate Club, 135 Fisher Loop, Main Post, Presidio
BBDAs 1A and 2 are located on a sloping bluff above the Pacific Ocean, south of the Golden Gate Bridge, and west of the Golden Gate Bridge Highway and Transportation District corporation yard. The sites are open space, vegetated primarily with non-native species. The Coastal Trail runs roughly north-south through BBDA 1A and to the east of BBDA 2.
BBDA 1A contains old asphalt roofing material from the adjacent batteries Cranston and Marcus Miller. The material consists of asphalt pieces, brick fragments, and tar-permeated sand. The material either eroded from the batteries or was removed from the batteries and disposed of in the area. At BBDA 1A, an estimated 4,400 cubic yards of asphalt material and soil contain polycyclic aromatic hydrocarbons (PAHs), metals, and one pesticide at levels that pose a potential risk to human health or the environment.
At BBDA 2, the Army disposed of debris and fill material. The debris fill is a mixture of soil, construction debris, landscaping debris, and other miscellaneous debris (e.g., cans, bottles, and glass). Approximately 6,700 cubic yards of debris fill and soil are contaminated with metals at levels that pose a potential risk to the environment.
Proposed Cleanup Alternative
The proposed cleanup alternative for both BBDA 1A and 2 is excavation. The excavation remedy consists of removal of asphalt material, debris, and soil to achieve cleanup levels, transportation to and offsite disposal of excavated materials at a permitted landfill, and backfill of the excavations with clean soil.
The Draft FS/RAPs and CEQA Draft Negative Declaration will be issued for public comment on December 5, 2012. The public comment period extends from December 5, 2012 through January 5, 2013. After the public comment period ends, DTSC will respond to public comments and issue Final FS/RAPs. The cleanup actions are scheduled to commence in spring 2013 and conclude by fall 2013.
