A. The Groundwater Protection Overlay District is hereby divided into the following zones: A, B, and C.
1. Zone A: Identified as the primary source of water for the Municipal well aquifer and as the area most likely to transmit groundwater contamination to the Municipal wells. Zone A is more restrictive than Zones B or C. This zone extends four hundred feet (400') from each well.
a. Permitted Uses - Zone A: The following uses are permitted uses within the Groundwater Protection Zone A. Uses not listed shall be considered prohibited uses:
Parks, provided there is no on-site waste disposal or fuel storage tank facilities associated with this use.
Playgrounds.
Residential, commercial, and industrial property, which is Municipally sewered, and free of flammable and combustible liquid and underground storage tanks (USTs).
Trails such as bike, skiing, nature, and fitness trails.
Wildlife areas.
b. Separation Distances: The following minimum separation distances shall be maintained in Zone A:
(1) Fifty feet (50') between a well and storm sewer main.
(2) Two hundred feet (200') between a well and any sanitary sewer main, sanitary sewer manhole, lift station, or single-family residential fuel oil tank. A lesser separation distance may be allowed for sanitary sewer mains where the sanitary sewer main is constructed of water main materials and joints and pressure tested in place to meet current American Waterworks Association (AWWA) C600 specifications. In no case may the separation distance between a well and sanitary sewer main be less than fifty feet (50').
2. Zone B: Identified as a secondary source of water for the Municipal wells because of the large cone of depression and a greater time of travel. Zone B is less restrictive than Zone A, but more restrictive than Zone C. This zone extends six hundred feet (600') from each well.
a. Permitted Uses - Zone B: The following uses are permitted uses within the Groundwater Protection Zone B. Uses not listed shall be considered prohibited uses:
All uses listed as permitted uses in Zone A.
Aboveground petroleum product storage tanks less than six hundred sixty (660) gallons. All new or replaced tanks shall be installed in compliance with chapter ATCP 93, Wis. Adm. Code.
Residential, commercial, and industrial property which is Municipally sewered or has a State-approved sewer and septic system.
b. Separation Distances: The following minimum separation distances shall be maintained in Zone B:
(1) Four hundred feet (400') between a well and a septic tank or soil adsorption unit receiving less than eight thousand (8,000) gallons per day, a cemetery or a stormwater drainage pond.
3. Zone C: Identified as the Groundwater Protection Overlay District, excluding those areas within Zone A and Zone B. This zone extends one thousand feet (1,000') from each well.
a. Permitted Uses - Zone C:
All uses listed as permitted in Zone A and Zone B. Individuals and/or facilities may make a request to the City to permit additional land uses in Zone C.
b. Separation Distances: The following minimum separation distances shall be maintained:
(1) Six hundred feet (600') between a well and any gasoline or fuel oil storage tank installation that has received written approval from the Wisconsin Department of Agriculture, Trade, and Consumer Protection (DATCP) or its designated agent under chapter ATCP 93, Wis. Adm. Code.
B. Prohibited Uses: The following uses are prohibited within the Groundwater Protection Overlay District:
Any property with residual groundwater contamination that exceeds chapter NR 140 enforcement standards that is shown on the Department of Natural Resources' geographic information system registry of closed remediation sites.
Any solid waste storage, transportation, transfer, incineration, air curtain destructor, processing, wood burning, one time disposal or small demolition facility.
Bulk fuel storage facilities.
Coal storage area.
Gasoline or fuel oil storage tanks that have not received written approval from DATCP or its designated agent under chapter ATCP 93, Wis. Adm. Code.
Pesticide or fertilizer handling or storage facilities.
Salt or deicing material storage area.
