R309-605-9. New Surface Water Sources of Drinking Water

(1) Prior to constructing a new surface water source of drinking water, each PWS shall develop a preliminary evaluation report (PER) which demonstrates that the source location has been chosen such that the number of uncontrolled sources in zones 1 and 2 is minimized. If the source water is not currently classified as Class 1C under UAC R317-2, the PWS must request such a classification from the Water Quality Board for zones 1 and 2. The PWS must also request that the source water be categorized as High Quality Waters - Category 1 or 2 under UAC R317-2-3 (Antidegradation Policy), if applicable. In addition, engineering information in accordance with R309-515-4 and R309-515-5 (general source development and surface water source development requirements) must be submitted to the Director concurrent with the PER. A complete DWSP plan is required, one year after approval of the PER and after construction of the source intake, following the requirements of R309-605-7.

(2) Preliminary Evaluation Report (PER) for New Sources of Drinking Water - PERs shall cover all four zones. PERs should be developed in accordance with the "Standard Report Format for New Surface Sources." This document may be obtained from the Division. PWSs shall include the following four sections in each PER:

(a) Delineation Report for Estimated DWSP Zones - The same requirements apply as in R309-605-7(3).

(b) Susceptibility Analysis and determination (including inventory)- The same requirements apply as in R309-605-7(4).

(c) Land Use Map - A land use map which includes all land within zones one and two and the primary use of the land (residential, commercial, industrial, recreational, crops, animal husbandry, etc). Existing maps or GIS data may be used to satisfy this requirement.

(d) Documentation of Division of Water Quality classification of source water - with reference to R317-2, provide documentation of the classification of the source waters by the Water Quality Board/Division of Water Quality (see also R309-605-9(1)), and of any associated petition for a change in classification.

(3) DWSP Plan for New Sources of Drinking Water - The PWS shall submit a DWSP Plan in accordance with R309-605-4 for any new surface water source of drinking water within one year after the date of the Director's concurrence letter with the PER. In developing this DWSP Plan, PWSs shall refine the information in the PER by applying any new characteristics of the source.
