Environmental Components:
The U.S. Environmental Protection Agency (EPA), under Comprehensive Environmental Response, Compensation, and Liability Act of 1990 (CERCLA) and the Superfund Amendments and Reauthorization Act of 1986 (SARA), desired to have a preliminary assessment (PA) of the Former Marshcrust Area – West End of the City of Alameda (Former Marshcrust) site, Alameda, California.
The purpose of the PA is to review existing information on the site and its environs to assess the threat(s), if any, posed to public health and welfare, or the environment and to determine if further investigation under CERCLA/SARA is warranted. The scope of the PA includes the review of information available from federal, state, and local agencies and performance of an onsite reconnaissance visit.
Using these information sources, the site is then evaluated using the EPA’s Hazard Ranking System (HRS) criteria to assess the relative threat associated with actual or potential releases of hazardous substances at the site. The HRS has been adopted by EPA to help set priorities for further evaluation and eventual remedial action at hazardous waste sites. The HRS is the primary method of determining a site’s eligibility for placement on the National Priorities List (NPL). The NPL identifies sites at which EPA may conduct remedial response actions. This report summarizes the findings of these preliminary investigative activities.
The Alameda Point is comprised of 2,675-acres and is adjacent to the Alameda Facility/Alameda Annex property on the western end of Alameda island. Approximately 75-acres of this land is within the boundaries of the Former Marshcrust site. Prior to construction of Alameda Point, use of the western tip of Alameda Island consisted of farming. Railroad yards were built over the western tip of Alameda Island.
