(A) Zone 1, minimum setback zone. This chapter incorporates the state’s Environmental Protection Act § 14.2, being 415 ILCS 5/14.2, which provides for the establishment of a 200 feet minimum setback zone for potable water supply wells, or 400 feet for more vulnerable types of permitted or existing community water supply wells. To facilitate the implementation of the siting prohibitions for community water supply wells located within the jurisdiction of the Planning and Zoning Department, a minimum setback zone (Zone 1) is hereby adopted for each community water supply well designated in the attached Exhibit 1 (see column headed “setback”), as determined by the Illinois Environmental Protection Agency.
(B) Zone 2, maximum setback zone. This chapter incorporates the state’s Environmental Protection Act § 14.3, being 415 ILCS 5/14.3, which provides the authority for any county or municipality served by a community water supply well to adopt a maximum setback zone. Specific rules and guidelines for the establishment of maximum setback zone protection for community water supply wells are provided in the publication entitled Maximum Setback Zone Workbook, Community Water Supply Groundwater Quality Protection, July 1990, available from the Planning and Zoning Department. A maximum setback zone (Zone 2), as designated by Exhibit 2, is hereby adopted for each community water supply well listed in Exhibit 2.
(C) Zone 3, five-year recharge area. The county hereby recognizes that certain communities have provided for groundwater modeling studies to delineate time-of-travel recharge areas for their community water supply well(s). To assure consistency in the quality of the modeling studies, the minimum time of travel requirements are provided in the publication entitled, Guidance Document for Groundwater Protection Needs Assessments, January, 1995, available from the Planning and Zoning Department. Communities utilizing this division (C) must provide the Planning and Zoning Department a technical completeness determination document signed by the agency to assure that minimum standards for delineation are met. A five-year recharge area (Zone 3) is hereby adopted for each groundwater recharge area delineation map set forth in Exhibit 3. A copy of each such map shall be on file with the County Planning and Zoning Department.
(D) Intergovernmental agreements. Where the 1,000-foot boundary of the maximum setback zone and/or the five-year recharge area encompasses county and municipal boundaries, the county may enter into intergovernmental agreements with local units of governments, including water districts, to affect a common ordinance protecting the community water supply in question. Pursuant to formal agreements with other responsible units of government, the county may delegate and share permitting, inspection, and enforcement authority as specified in such agreements.
