Brentwood CA, FORMER BRENTWOOD GUN CLUB (07860001) Housing Development that is banned by Deed Restriction

Site History

Envirostor (State of California) page

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.

Tyco, previously known as Raychem is an electronic manufacturer. Raychem had a hazardous waste facility permit and closed its hazardous waste management units. DTSC has been overseeing corrective action at Tyco under a corrective action consent agreement. The main contaminant is PCBs. Soil removal was completed to industrial levels. LUC has been entered into and filed with County. Tyco is currently conducting long term groundwater monitoring.

[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.

EPA Superfund Site: INTERSIL INC./SIEMENS COMPONENTS CUPERTINO, CA

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?

“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. “
