The following table identifies uses which have varying potential to contaminate groundwater sources. These uses have been classified according to the risk of contamination in each protected zone as follows:

Permitted Uses (P)—The risk of contamination is considered relatively low in the specified zone if regulatory requirements and best management practices are implemented and, therefore, the use is permitted.

Conditional Uses (C)—The risk of contamination is moderate in the specified zone. The use may be permitted only after conditional use review and approval by the planning commission. Approval is subject to implementation of best management practices and compliance with other reasonable conditions as may be established by the planning commission. The Utah Division of Drinking Water Quality shall review all conditional use requests.

Prohibited Uses (X)—The risk of contamination is very high in the specified zone. The use is not permitted.
