Subject:TemporaryException to R309-600-13(2)(b)(ii), Septic in zone 2 of an unprotected aquifer and Concurrence, Drinking Water Source Protection Plan for the Sports Complex Production
Well;
Lewiston City; Water System #03009, Source No. WS005
This Temporary Exception Expires on December 31, 2028.
Dear Paul Swainston:
The Division of Drinking Water (the Division) received the Drinking Water Source Protection (DWSP) plan for the Sports Complex Production Well from your consultant, John De Leon and
JUB Engineers on August 5, 2024, with requested information submitted August 13, 2024 and September 12, 2024.
We have completed our review of the DWSP plan, stamped and signed by John De Leon, P.E., and dated September 12, 2024, and find that the plan basically complies with the applicable portions
of Utah’s Administrative Rules for Public Drinking Water Systems. The Division concurs with this plan. We commend you for establishing a program to protect this source from present and
future contamination. This plan must be updated often enough to ensure that it reflects current conditions in your protection zones.
The due date for submitting the next updated plan is December 31, 2028.
Exception Request
The basis for your request for an exception to R309-600-13(2)(b)(ii), septic in zone 2 of an unprotected aquifer is that water quality tests that have been performed for this well in
the past have indicated low levels of nitrates. Based on these tests, the impact of the septic tank on the water quality of the well has been historically negligible. You propose to
complete quarterly water testing for nitrates in the Sports Complex Production Well to verify that levels are below the acceptable maximum contaminant level and to increase frequency
of public education; more specifically, septic tank best management practices fact sheets sent to the owner of this PCS twice a year to meet the intent of the rule.
On this basis, an exception to R309-600-13(2)(b)(ii), septic in zone 2 of an unprotected aquifer, is hereby granted for the Sports Complex Production Well (WS005).
This Temporary Exception expires onDecember 31, 2028.
You will be required to re-submit an exception request along with confirmation that all conditions outlined in this temporary exception have been fulfilled and submit it with your DWSP
plan update due December 31, 2028.
Exceptions granted by the Division include an expiration date to ensure that the basis and conditions for granting the exception are verified periodically and that the drinking water
quality remains protected. After receiving your request, the Division will determine whether this exception can be re-issued.
This Temporary Exception may be rescinded any time if new evidence indicates that the conditions of this exception are no longer being met or a public health risk exists due to this
exception.
Please be aware that the source protection zones for this source have now been incorporated into the Division’s Geographic Information System (GIS) database. In addition, these zones
