At the time of the inspection EHD staff determined <br /> that your septic systems may serve more than 20 people per day. Since ground water is a <br /> source of drinking water, subsurface waste disposal is regulated under the United States Safe <br /> Drinking Water Act. <br /> EHD has implemented a Local Agency Groundwater Protection/Underground Injection Control <br /> (UIC) Program in accordance with guidelines prepared by the United States Environmental <br /> Protection Agency(USEPA). The primary focus of the program is to protect drinking water by <br /> identification and evaluation of subsurface disposal of waste fluids that may lead to the <br /> degradation of drinking water supplies. <br /> By definition any septic system that serves more than 20 people per day is a shallow injection <br /> well, so your facility has been placed on the EHD list of UIC sites. If your septic systems are <br /> used for the disposal of solely sanitary waste and serve fewer than 20 persons per day , please <br /> inform EHD of this in writing. In addition, please provide in writing the disposal method for your <br /> storm water(on site pond, ditches, dry wells). Following review of the information submitted, <br /> EHD will evaluate if your storm water disposal method meets the definition of an underground <br /> injection well and if modifications are necessary and/or if it should be inventoried as an <br /> underground injection well. Enclosed is an "Inventory of Injection Wells"form that is to be <br /> completed and submitted to USEPA in San Francisco (address on page 2 of form) if your facility <br /> has a septic or storm system that meets the definition of an underground injection well. Please <br /> submit a copy of the form to EHD if it is completed. <br /> The above requested information about your facility should be submitted to EHD by July 1, 2005. <br /> If you have any questions contact me at (209)468-3449. <br /> Donna Heran, REHS, Director <br /> Environmental Health Department <br /> Margaret Lagorio, Supervising REHS <br /> Unit IV <br /> Enc. <br />
