31 <br /> to meet the wellhead rules for WHPA delineation. Minnesota wellhead rules <br /> require evaluation and consideration of the following criteria: <br /> 1. time-of-travel <br /> 2. flow boundaries <br /> 3. dailyvolume . <br /> 4. groundwater flow field <br /> 5. aquifer transmissivity <br /> After evaluating the criteria, and in conjunction with the City of St. Anthony staff, <br /> WSB will identify the delineation approach that best serves the needs of the <br /> public water supply system and meets the rule requirements. <br /> B. Pre-Delineation Meeting. After completion of the method scoping,WSB will <br /> meet with the City of St. Anthony staff and MDH staff to discuss the delineation <br /> criteria, the conceptual model, and the WHPA delineation method. <br /> C.

Well#5,unique number 200524 <br /> A time-of-travel of 10 years will be used to determine the final WHPA boundary, <br /> and 1-year as well as 5-year time-of-travel zones will be shown on maps in the <br /> project deliverables. <br /> D. Delineate the Drinking Water Supply Management Area(DWSMA). WSB will <br /> work with MDH to delineate the DWSMA using the boundary definitions <br /> contained in the wellhead protection rules (MR 4720.5 100, subp. 13) <br /> E. Draft cooperative agreements.

WSB will review the vulnerability <br /> assessment conducted by MDH to phase the well into the Wellhead Protection <br /> (WHP)program to.determine whether it should be revised. Data collected for the <br /> WHPA will be used to prepare an aquifer vulnerability assessment of the entire <br /> DWSMA. <br /> IV. Delineation/Vulnerability Reporting/Deliverables <br /> A. Draft Report. WSB will prepare and submit to MDH a draft report to satisfy the <br /> wellhead protection reporting requirements for WHPA delineations and <br /> vulnerability assessments. The draft report will provide sufficient documentation <br /> to meet wellhead protection rule (MIZ 4720.5330)requirements for the WBPA <br /> delineation and vulnerability assessment. <br /> 1. Draft Report. The draft report will describe the data elements considered <br /> in conducting the delineations and assessments, and the technical approach <br />
