Subitem (2) requires that stormwater management facilities <br />be designated and installed consistent with Field Offices <br />Technical Guide of the Minnesota Soil and Water Conservation <br />districts and the United States Soil Conservation Service. <br />This provision is needed to insure that the constructed and <br />installed facilities operate to handle the runoff they are <br />designed for. <br />Item (3) requires that construction of new sto^water <br />outfalls to public waters be equipped with devices for <br />filtering or settling of suspended solids and skimming of <br />surface debris before discharge. These provisions would <br />result in minimizing pollution in water bodies and enhancing <br />qiial -i i-y _ _ _ _ ___ _ _ _ _ _ _ _ _ <br />6120.3400 SAJIITARY PROVISIONS <br />Subpi—tt—purpose. <br />This subpart is proposed to be repealed because the intent <br />and purpose are already incorporated in 6120.3500, Subp. 1 <br />and Subp. 2 and 6120.3400, Subp. 3. <br />Subp. 2. Water Supply. <br />One of the changes made in these subparts requires the water <br />quality standards of the Minnesota Department of Health and <br />Minnesota Pollution Control Agency to be adopted as minimum <br />standards or to be exceeded for any public or private supply <br />of water for domestic purposes. This provision would <br />promote the public health and welfare of shoreland <br />residents. The other change requires that wells no longer <br />in service be abandoned according to water well abandonment <br />standards of the Minnesota Department of Health. While the <br />number of abandoned wells in Minnesota is unknown, it is <br />believed to be very high. Officials of the Minnesota <br />Department of Health estimate the number of improperly <br />abandoned wells to be 1/2 million to 1 1/2 million. If <br />wells are not abandoned according to standards, they are a <br />threat to public health and welfare since they become <br />conduits through which contaminants reach and pollute <br />groundwater aquifers. Almost 100% of rural Minnesota and <br />some cities depend on ground water for their domestic water <br />supply. As such its protection is important to prevent <br />disastrous consequences on public health and welfare.
