The Brentwood Gun Club began operation at the site in 1964. The facility had a trap and skeet field, rifle and pistol ranges, and an air gun range. Prior to that the property was used as a sanitary landfill. Contra Costa County acquired the property in August 1999 in preparation for the construction of the State Route 4 Bypass through the site. A Removal Action Workplan was implemented for consolidation of lead-contaminated soil under the proposed roadway and capping contaminated outside of the freeway footprint with 1-2 feet of clean fill. Some soils that exceeded residential screening levels but were below commercial screening levels for lead were left in place without a cap. A Land Use Covenant was filed with the County Recorder that restricts future usage of the site for residential, child care, or school facilities. Annual inspections are required as part of Operations and Maintenance.
Editors note; this deed restriction is current and yet it is a housing development even though it is prohibited in the land use covenant.
Raychem Corporation (Raychem) operated a facility which manufactured high technology plastic and electrical insulation products and also engaged in management of hazardous waste pursuant to a hazardous waste facility permit (Permit). The Permit, issued in 1983 by the California Department of Health Services, the predecessor of DTSC, allowed operation of a wastewater treatment system, a hazardous waste storage yard and a potassium ferrocyanide tank farm. On January 9, 1997, DTSC approved the closure activities of aboveground portions of these hazardous waste management units.

[VIEW COVENANT] 1/19/2007 For some strange reason, the state website does not list the site management requirements but if you click on the View Covenant you can read what is required, this is a deed restriction.
1.2. Raychem Corporation, the Covenantor’s predecessor, manufactured hightechnology plastic and electrical insulation products. It also engaged in management of hazardous waste pursuant to a hazardous waste facility permit issued by the California Department of Health Services, the predecessor agency of the Department. The hazardous waste facility permit allowed Raychem Corporation to operate a wastewater treatment system, a hazardous waste storage yard and a potassium ferrocyanide tank farm. On January 9, 1997, the Department approved the closure activities of the aboveground portions of these hazardous waste management units. Raychem Corporation proceeded with corrective action under the Department’s oversight to address the release of hazardous waste in soil and groundwater. Raychem merged with the Covenantor in 1999. The Covenantor has conducted corrective action at the Property under the Department’s oversight, including removal of contaminated soil, installation of an engineered multi-media cap over an area of subsurface contamination and groundwater monitoring.

As a result of historical operations at the Property, certain hazardous materials, including volatile organic compounds, semi-volatile organic compounds, PCBs, dioxins and dibenzofurans were released into the soil and groundwater at the Property.
Map of the site is on page “The 22-acre site located at 400 Carolan Avenue, in Burlingame. It is the existing Burlingame High School (built in the late 1910s). DTSC reviewed a Phase I Environmental Site Assessment (Phase I) and determined that a Preliminary Environmental Assessment (PEA) was required.
A Preliminary Environmental Assessment (PEA, 2003/04) investigated the site for metals, organochlorine pesticides, polychlorinated biphenyl (PCB), total petroleum hydrocarbons, volatile organic compounds and metals. The PEA report identified lead and PCB around the main building, and elevated arsenic in the athletic field. DTSC issued further action for Lead/PCB, and additional investigation for the arsenic.
Supplemental site investigations defined the extent of lead impacted soils and identified elevated levels of arsenic in soils in various areas of the campus. A Removal Action Workplan (RAW) for lead and PCBs was approved for implementation in December 2005 for areas around the main building. The removal began in January 2006 and was completed in June 2007. Financial hardship caused delays in the completion of the removal. Once financial issues were resolved, the District took confirmation samples to confirm clean-up goals were met. Continue reading “BURLINGAME HIGH SCHOOL (41820008) on toxic waste site”→
“Naval Station Treasure Island (NSTI) is located in San Francisco Bay (Bay), midway between San Francisco and Oakland, California. The facility consists of two contiguous islands: Treasure Island (TI), which is approximately 550 acres, and Yerba Buena Island (YBI), which is approximately 550 acres. Stormwater outfalls and offshore sediments (Site 13) encompass approximately 563 additional acres. Treasure Island is a manmade island that is anchored to a natural rock island (YBI), that was constructed of materials dredged from the Bay in 1936. The island was developed to be the site of the 1939 Golden Gate International Exposition. In response to a Navy request, in 1941, the City of San Francisco leased TI to the Navy for the duration of World War II. After the war, the city agreed to transfer the deed for TI to the Navy in exchange for government-owned land south of San Francisco where the San Francisco International Airport was later built. TI provided administrative and support facilities for processing Pacific-bound naval personnel, and for the administrative operations of other Navy, Marine Reserves, and non-military Federal activities. Military activities at YBI date back to 1866. In 1993, NSTI was designated for closure under the Base Realignment and Closure Act (BRAC) of 1990. The base was closed on September 30, 1997, and is currently in the transfer process.
In April 1988, a Preliminary Assessment/Site Inspection (PA/SI) Report of the facility was prepared for the Naval Energy and Environmental Support Activity (NEESA). Based on information from historical records, aerial photos, agency contacts, field inspection, and personnel interviews, a total of 20 areas were identified with potential contamination and for additional site investigation. These identified acres included: a medical clinic; a former foundry; a boiler plant; an old bunker; stormwater outfalls; a refuse transfer area; a car hobby shop; an oil recovery waste facility; a seaplane maintenance shop; an exchange service station; a hydraulic training school; a painting shop; two storage shed areas; a landfill; and fire training fuel tank releases. During subsequent investigations additional sites were identified that brought the total number of sites to 33. Contaminants include: low-level radioactive waste, polychlorinated biphenyls (PCBs), dioxins, pesticides, paints, waste oil and fuel, solvents, asbestos, acids, and heavy metals.
Since closure of the base in 1997, nearly all of TI has been leased to the City of San Francisco for a variety of uses including movie production, an elementary school and daycare center, approximately 750 rental housing units, and an Olympic sailing school at Clipper Cove. In addition, 35 acres were transferred to the Federal Department of Labor for the establishment of a job corps center on TI. Portions of YBI were also transferred to the State to facilitate the construction of the new East Bay Bridge. The remainder of the land on YBI is comprised of housing that is controlled by the City of San Francisco and a U.S. Coast Guard Station that occupies the southern half of the island.

“The Site was originally marshland on the margin of the Mission Bay which was filled with dune sands and silt in the late 1800’s and early 1900’s for development. The Site has been used for residences, commercial lodging and parking lots from the 1899 until it was purchased by the San Francisco Redevelopment Agency in 1991. ASIAN Inc. has redeveloped the property into affordable housing units and one commercial unit.” Continue reading “SF – 518 MINNA STREET SAN FRANCISCO, CA 94103 STATE RESPONSE OR NPL”→
Apple Computer, Kaiser Permanente Child/ado Psy and Kaiser Permanente – CDRP (Chemical dependency recovery program) are located on the EPA Superfund Tri-Site where there are toxic chemicals in the ground that emerge as toxic vapor and the deed restrictions are present to stop organizations from having hospital facilities on the site. Strange thing is Kaiser Permanente operates two facilities on the site. So I would imagine that each patient must be signing a waver when they visit the facility?
I know Apple does not have daycare at their facility they would not be stupid enough to do such a thing. I find it strange that people are willing to work on a toxic waste site. But I guess they know what they are doing. Surely Apple would inform everyone who has access to the site, including delivery drivers as they are required by the deed restrictions?
Given the Covid Epidemic it is clear that constant exposure to TCE contamination damages the immune system and may have caused the employees at Apple to be further susceptible to Covid infections. –
“The Intersil/Siemens Superfund Site includes the following three areas: 1) the former Intersil facility, located at 10900 North Tantau Avenue, Cupertino; 2) the former Siemens facility, located at 10950 North Tantau Avenue, Cupertino; and 3) the Off-Site Study Area, located north of and hydraulically downgradient from the two former facilities in Sunnyvale. Investigations conducted in the 1980s as part of the California Regional Water Quality Control Board’s (Regional Board’s) underground storage tank (UST) leak detection program found volatile organic compounds (VOCs) in soil on- and off-site. The primary contaminant of concern at the site is the VOC, trichloroethene (TCE).
• Former Intersil Facility – Intersil, Inc. operated at the property from 1968 to 1988 and initiated investigations in 1983. The potential sources of contamination were removed between 1986 and 1988, including waste neutralization systems, a waste solvent tank, and an above-ground chemical and hazardous waste storage area.
• Former Siemens Facility – Litronix and its successor, Siemens Microelectronics, Inc., operated at the property from 1970 to the mid-1990s. Until 1982, liquid wastes were stored in five USTs that were removed in 1982. From 1982 until cessation of operations, liquid wastes previously stored in USTs were temporarily placed in the hazardous materials storage area for off-site disposal or recycling. Investigations began in 1982 after the discovery of contaminants during the removal of the USTs.
Drinking water for Sunnyvale and Cupertino is not affected by this contamination. Calabazas Creek, an intermittent stream, is located approximately 1,500 feet east of the site. “
