Home Browse Search

Chapter 1 - Introduction 1.1 Background The wellhead protection(WHP)plan for the City of Pequot Lakes is being amended in cooperation with the Minnesota Department of Health(MDH). The second part of the city's original WHP Plan was approved by MDH July, 15,2003. The State WHP Rule requires community water suppliers to amend their plan every 10 years(starting in year 8) so that the plan remains current and reflects any changes to the public water supply system, land use, contaminant issues, etc.that may have occurred during the time the original WHP plan was in place. WHP plans are amended to keep up with new challenges and opportunities to protect the public water supply wells and aquifer used by the city. This plan contains specific actions that the city will take to fulfill WHP requirements that are specified under Minnesota Rules,part 4720.5510 to 4720.5590. Also,the support that Minnesota state agencies, federal agencies, Crow Wing County, and others will provide is presented to identify their roles in protecting the city's drinking water supply. The plan is effective for 10 years after the approval date specified by MDH and the city is responsible for implementing the WHP plan of action, as described in Table 9 of this report. Furthermore,the city will evaluate the status of plan implementation at least every two-and-one-half years to identify whether its WHP plan is being implemented on schedule. 1.2 Plan Appendices Much of the technical information that was used to prepare this plan is contained in the appendices but is summarized in the main body of this plan. In particular: • Appendix I contains the first part of the plan, consisting of the delineation of the wellhead protection area(WHPA),the drinking water supply management area(DWSMA),and the vulnerability assessments for the public water supply well(s)and the DWSMA. This part of the plan is summarized in Chapter 3. • Appendix H contains the inventory of potential contamination sources. This inventory is discussed in Chapter 4 in terms of assigning risk to the city's water supply and is also discussed in Chapter 6,relating to issues,problems or opportunities. • Appendix III contains the contingency strategy to provide for an alternate water supply if there is a disruption caused by contamination or mechanical failure. This information is discussed in Chapter 11. 1.3 Plan Development Milestones: Scoping Two Meeting Held October 9,2012 (4720.5340, Subp. 1) Scoping Two Letter Dated November 7,2012 (4720.5340, Subp. 2) WHP Management Plan Submitted to March 7, 2013 Local Units of Government(LGU's) (4720.5340, Subp. 1) WHP Management Plan Review Received from LGU's May 7,2013 (4720.5350, Subp. 2 1
