/ 3 CONDITIONAL APPROVAL Because the operation of the high capacity water supply is not expected to cause any significant reduction in groundwater availability to the nearest public utility well, the construction and operation of the proposed batch plant supply well is hereby approved, as described in this approval, subject to the conditions noted below. The Department reserves the authority to limit the pumpage in any amount that may be necessary to eliminate excessive drawdown in any public utility well that may be affected. If the operation of the well adversely affects the operation of any private wells on neighboring properties, this Department approval will not negate the protection to which private well owners are entitled under Wisconsin case law relating to groundwater. Approval by the Department does not relieve the property owner or well operator of any liability which may result from injury or damage suffered by any person upon operation of the well. • If construction of the proposed well has not commenced within two years from the date of this letter, this approval shall become void. After two years, therefore, a new application must be made for approval of the plans and specifications before any construction work is undertaken. 1. A chlorine residual shall be maintained in the drilling water during the entire drilling operation of the new well. 2. Notification of the proposed time of drilling the well shall be given to the Department of Natural Resources, Private Water Supply Section at (608) 267-7652 not less than 48 hours prior to the beginning of the drilling operation. 3. Notification of the proposed time of grouting shall be given to the Department of Natural Resources Southern District office at Madison, telephone number (608) 275-3302, not less than 48 hours prior to the beginning of the grouting operation. In conducting this grouting, the Halliburton double or single plug method may only be used if prior approval is obtained in writing from the Department. 4. All sampling, reporting and other requirements for both the construction and operation of the new well shall be complied with. These requirements include the well driller preparing and submitting a construction report of the well -to the Department within 30 days after completion of drilling of the well. For the new well, the construction reporting also requires that the well driller collect drill cuttings at 5 foot intervals throughout the depth of the well and at each change in formation. The samples must be sent to the State Geologic Survey for examination and preparation of an accurate geologic log of the well. 5. A sign stating "WATER FROM THIS WELL SHALL NOT BE USED FOR HUMAN CONSUMPTION OR FOR THE WASHING OR PREPARATION OF FOOD PRODUCTS" shall be posted at the site of the well and thereafter maintained in a legible condition. 6. Any chemicals that may be injected into the nonpotable well discharge piping shall be injected in strict compliance with all the requirements of s. NR 112.38, Wis. Adm. Code. If a Reduced Pressure Principle Backflow Preventer (RPPBP) valve is used for the injection of any chemicals, then s. ILHR 82.20
