(formerly known as: Primex Technologies Tracy Test Facility)",NOE,7/29/2008,7/29/2008,"The corrective action process for this facility was approved in April of 2001, and has identified an area which requires further remediation due to the presence of Mineral Oil in the groundwater. The Mineral Oil is considered non-toxic, but must meet Drinking Water Health Advisory requirements for taste and odor threshold. The taste and odor threshold of 100 ppb for Total Petroleum Hydrocarbons (TPH) for Diesel-Ranged is recommended by the Central Valley Regional Water Quality Control Board. The source of the Mineral Oil came from an empty above-ground storage tank SWMU #21 which was previously closed and removed from the facility. The proposed corrective action revised remedy selection consists of the following activity: adding a 2% hydrogen peroxide solution to the contaminated groundwater via existing piping as an enhanced natural attenuation. A trial test will be performed in one of the Wells. After two weeks time, groundwater samples will be take, to evaluate the effectiveness of the treatment. If results show that biodegradation is occurring, the following will take place. At the beginning of the month for a period of three months, 500 hundred gallons of hydrogen peroxide will be poured into three up-gradient monitoring wells in the area of the groundwater plume. Groundwater monitoring will be conducted quarterly for four quarters which is equivalent to one year of time. The effectiveness of the treatment and need for further monitoring will be evaluated by DTSC after a year of groundwater monitoring. This is the final step required in the corrective action process to clean the site to standards appropriate for residential use of the property. At the conclusion of remediation period, DTSC will determine whether further corrective action will be required for the site.
