C. 27701 <br /> Y <br /> Daar Mr. Roland: - <br /> i . The Division of Environmental Management (DEM) is proposing <br /> . to change the current water supply classification by including <br /> three classes which would be distinguished by the degree of <br /> watershed protection provided; Your water supply currently has an <br /> A-II stream classification and with the proposed rule change this <br /> will automatically be converted to the general water supply <br /> . . classification w.s.-Iii,. we are writing you to determine if your <br /> community is interested in pursuing a more protected water supply <br /> classification (W.S.-I and W.S.-II) . <br /> For the past thirty years we have had the A-I and A-II <br /> classifications for water supplies. The only difference between <br /> A-I and A-II is the amount of treatment required prior to <br /> disinfection. However, this existing classification scheme does • <br /> not evaluate a water supply from a watershed perspective, take <br /> into consideration all point and nonpoint sources of pollution, <br /> or encourage local governments -to select the safest source of <br /> water. DEM is therefore proposing to change the current <br /> classification to reflect our growing concern for the water <br /> quality of these sources in light of the unknown amount and type <br /> of chemicals (which may be potentially toxic) that are being <br /> released into our water-bodies. <br /> The new classification system being proposed by DEM includes <br /> three levels of water supplies (W.S.-I, W.S.-II, and W.S.-III) . <br /> The level would be defined according to the amount and type of <br /> permitted point source discharges located in the watershed, as <br /> well as the control of nonpoint sources of pollution being <br /> 67 provided. The enclosed attachment describes the three <br /> classification of water supplies in detail. <br /> • <br /> PO.
