19.20.000 Table 20-1 Use Matrix For Potential Contamination Sources

TABLE 20-1

USE MATRIX FOR POTENTIAL CONTAMINATION SOURCES

The following table identifies uses which have varying potentials to contaminate groundwater sources. These uses have been classified according to the risk of contamination in each protection 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 (BMP) are implemented and, therefore, the use is permitted.

Conditional Uses (C) – The risk of contamination is considered relatively low in the specified zone. The use may be permitted only after conditional use review and approval by the Land Use Authority as defined in Section 19.01.135. Approval is subject to implementation of Best Management Practices (BMP) and compliance with other reasonable conditions as may be established by the Land Use Authority. 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.
