August 2009 7. What is required of public water suppliers as the regulated group? All public water suppliers are required to manage an inner wellhead management zone, a 200-foot radius surrounding a public water supply, by: A. Maintaining the isolation distances defined in the state Well Code (Minnesota Rules, Chapter 4725) for newly installed potential sources of contamination. B. Monitoring existing potential sources of contamination that do not comply with the isolation distances defined in the state Well Code. C. Implementing wellhead protection measures for potential contaminant sources in the inner wellhead management zone. In addition to the inner wellhead management zone requirements, owners and operators of community and nontransient noncommunity wells must prepare a wellhead protection plan which includes: A. A map showing the boundaries of the delineated wellhead protection area using the five criteria specified in the rule. B. A vulnerability assessment of the well and the wellhead protection area. C. An inventory of potential sources of contamination within the wellhead protection area based on the vulnerability assessment. D. A plan to manage and monitor existing and proposed potential sources of contamination. E. A contingency strategy for an alternate water supply should the water supply be disrupted by contamination or mechanical failure. 8. Does a public water supplier have to own all the property within the inner wellhead management zone (200-foot radius of a public water supply well )? No. There is no requirement that a public water supplier own the property within the 200-foot radius which forms the inner wellhead management zone. 9. What impact does wellhead protection have on submitting plans for constructing a new community water supply well? The current procedures for submitting pre-construction plans to the Minnesota Department of Health, Administrative Unit, and the driller’s notification of intent to drill to the Well Management Section remain the same. The only change is a preliminary delineation of the wellhead protection area and assessment of the land use, based on existing data, must be completed and submitted with the pre- construction plans. This is required to assist with the siting of a new municipal well. This requirement does not apply to nonmunicipal community water suppliers nor to noncommunity water suppliers. The completion of a two-page form available from the Minnesota Department of Health will fulfill this requirement. A copy of this form can be obtained by calling 651-201-4700 or by visiting the website at: www.health.state.mn.us/divs/eh/water/swp/whp/fs/swpnwr.html. 10. Must contaminant source control measures be implemented before a wellhead protection plan is submitted to the department for approval? No. The plan must identify the measures that will be used and when they will be implemented over a ten-year period, following department approval of the plan.
