• Agenda Item 6A • • Environmental Board Meeting Date: May 30, 2007 Topic: Water Emergency and Conservation Plan Background: Public water suppliers that service more than 1,000 people are required to have a Water Emergency and Conservation Plan approved by the Department of Natural Resources (Minnesota Statutes 103G.291). These plans were first required in 1996 and must be updated every ten years. The Minnesota Department of Natural Resources has prepared a schedule for each public water supplier, with a due date for the City of Lino Lakes of October 15, 2007. The plan must address supply and demand reduction measures and allocation priorities and must identify alternative sources of water for use in an emergency. The current Water Emergency and Conservation Plan was created by TKDA in 1997 and revised in 2004 to meet the requirements of a federal mandate of the USEPA, under the Homeland Security Act. That federal mandate required the City of Lino Lakes to prepare a Water System Vulnerability Assessment and amend and update the Water Emergency and Conservation Plan with the purpose of evaluating the existing security of the water system. Analysis: The Water Emergency and Conservation Plan Benchmarks and Conservation Measures are below. The City must address these items through their report to the DNR. Benchmarks and Conservation Measures. Permit approvals will be based on meeting specified benchmarks listed below. If water demands exceed Benchmarks for unaccounted water, residential per capita, and peak demands then permit approval will be contingent on implementation of one or all the listed Conservation Measures or Programs until the benchmark is achieved.
