A. To protect source water from exposure to hazardous materials or practices that expose a well or spring that supplies water to a PWS, the source water protection overlay (SWPO) designation established pursuant to this chapter shall implement certain measures of protection for water sources appropriate to the risk posed by particular conductor activities. An SWPO designation shall be identified and configured to protect a well, spring, or surface water source from vulnerability to pollutants within a calculated ten (10) year time of travel (TOT) area determined by studies and mapping provided by DEQ. Original data concerning such studies can be obtained from DEQ.
B. Source water protection overlay (SWPO) designations shall be depicted on a map of the city of Payette that is designated as the official SWPO designation map. Each spring, well, or surface water intake that serves as a source for a PWS shall be located on the SWPO map. The official SWPO map of like date with the initial effective date hereof is hereby adopted as a component of this chapter and as a complement to the zoning ordinance of the city of Payette. Each subsequently identified PWS well, spring, or surface water intake shall hereby be automatically added to the SWPO map with the well, spring, or surface water intake location identified by its global positioning system coordinates, or by the same means that other wells, springs, or surface water intakes are located within DEQ records concerning PWS wells, springs, or surface water intakes as soon as DEQ studies concerning such PWS are complete. Even if a PWS well, spring, or surface water intake is not depicted on the SWPO map, it shall nonetheless be subject to the protection and limitations afforded by this chapter. No amendment of this chapter or map shall be necessary to apply the requirements of this chapter to any PWS source. Corrective amendments to the SWPO map can be made by administrative staff of the city of Payette upon a determination of factual propriety. (Ord. 1417, 2016)
