EDR Proprietary Manufactured Gas Plants <br /> The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants(manufactured gas plants) <br /> compiled by EDR's researchers. Manufactured gas sites were used in the United States from the 1800's to 1950's <br /> to produce a gas that could be distributed and used as fuel.These plants used whale oil,rosin,coal,or a mixture <br /> of coal,oil,and water that also produced a significant amount of waste.Many of the byproducts of the gas production, <br /> such as coal tar(oily waste containing volatile and non-volatile chemicals),sludges,oils and other compounds <br /> are potentially hazardous to human health and the environment_The byproduct from this process was frequently <br /> disposed of directly at the plant site and can remain or spread slowly,serving as a continuous source of soil <br /> and groundwater contamination. <br /> Date of Government Version:NIA Source: EDR,Inc. <br /> Date Data Arrived at EDR:NIA Telephone: N/A <br /> Date Made Active in Reports:NIA Last EDR Contact:NIA <br /> Number of Days to Update:N/A !Next Scheduled EDR Contact:N/A <br /> Data Release Frequency:No Update Planned <br /> COUNTY RECORDS <br /> ALAMEDA COUNTY: <br /> Contaminated Sites <br /> A listing of contaminated sites overseen by the Toxic Release Program(oil and groundwater contamination from <br /> chemical releases and spills)and the Leaking Underground Storage Tank Program(soil and ground water contamination <br /> from leaking petroleum USTs). <br /> Date of Government Version:04/24/2007 Source: Alameda County Environmental Health Services <br /> Date Data Arrived at EDR:04/26/2007 Telephone: 510-567-6700 <br /> Date Made Active in Reports:05/10/2007 Last EDR Contact:04/23/2007 <br /> Number of Days to Update: 14 Next Scheduled EDR Contact:07/23/2007 <br /> Data Release f=requency:Semi-Annually <br /> Underground Tanks <br /> Underground storage tank sites located in Alameda county. <br /> Date of Government Version:04/24/2007 Source: Alameda County Environmental Health Services <br /> Date Data Arrived at EDR:04/26/2007 Telephone: 510-567-6700 <br /> Date Made Active in Reports:05/07/2007 Last EDR Contact:04/23/2007 <br /> Number of Days to Update: 11 Next Scheduled EDR Contact:07/23/2007 <br /> Data Release Frequency:Semi-Annually <br /> CONTRA COSTA COUNTY: <br /> TC1930850.2s Page GR-19 <br />
