Draft North & East Metro Groundwater Management Area Plan 4-16 Other Appropriation Categories For appropriations other than municipal water supply, conservation measures are not specifically tracked by DNR.Typical permit language requires that the permittee shall,whenever practical and feasible, employ water conservation techniques and practices. Conservation requirements have been developed for some specific appropriation categories (e.g. golf courses) and a re applied to some permits or permit amendments. An estimated 5 percent of groundwater use in the GWMA is met by wells that do not require a DNR appropriation permit.There are also currently no conservation standards for the non-permitted groundwater users. Pollution containment pumping facilities are reviewed on a regular basis as part of overall site review under the applicable remediation program administered by the Minnesota Pollution Control Agency or Minnesota Department of Agriculture. For example, lower pumping rates were tested for the 3M pollution containment wells in Woodbury, but the lower rates were found to allow polluted groundwater to escape the containment system. In general, pumping more than is necessary is avoided because of the added costs for pumping,treatment and disposal. Industrial users may seek assistance from trade associations and from the Minnesota Technical Assistance Program (MnTAP)of the University of Minnesota to help find industry-tailored ways to prevent pollution and reduce resource use. More efficient water use can save businesses money by,for example, reducing energy costs and wastewater fees.These measures usually must be tailored to an individual facility. Gap Analysis and Recommendations Community%heater supply plans provide the best opportunity for the DNR to engage with public water suppliers and the Metropolitan Council on conservation.The required demand reduction measures will be an important component of the plans. Goals for residential per capita demand, maximum-to average-day demand, and unaccounted for water will also be set in these plans.These goals may need to be updated for water supply plans. Annual reporting of water use by category(residential, industrial, commercial, agricultural)should be made consistent between municipalities to enhance the accuracy of water use tracking. It is important for DNR to develop water use category and business sector specific techniques, practices and measures for all appropriation permits. Permit conditions for each category or sector should be more consistent. Information collected on these conservation related permit conditions should be evaluated and reported to support management of groundwater appropriations. Groundwater users not required to hold DNR permits should be responsible for conservation and reasonable water use measures. DNR has the option to require general permits for wells that pump below the current regulatory limit (10,000 gallong per day or 1,000,000 gallons per year)within the GWMA(Minn. Stat., sec. 103G.287, subd. 4). If required,the fee to request authorization under a 74
