This rule is promulgated by the Drinking Water Board as authorized by Title 19, Environmental Quality Code, Chapter 4, Safe Drinking Water Act, Subsection 104 of the Utah Code and in accordance with 63G-3 of the same, known as the Administrative Rulemaking Act.
Definitions for certain terms used in this rule are given in R309-110 but may be further clarified herein.
(1) All public water systems are required to monitor their water to determine if they comply with the requirements for water quality stated in R309-200. In exceptional circumstances the Director may modify the monitoring requirements given herein as is deemed appropriate.
(2) The Director may determine compliance or initiate compliance actions based upon analytical results and other information compiled by authorized representatives.
(3) If the water fails to meet minimum standards, then certain public notification procedures must be carried out, as outlined in R309-220. Water suppliers must also keep analytical records in their possession, for a required length of time, as outlined in R309-105-17.
(4) All samples shall be taken at representative sites as specified herein for each contaminant or group of contaminants.
(5) For the purpose of determining compliance, samples may only be considered if they have been analyzed by the State of Utah primacy laboratory or a laboratory certified by the Utah State Health Laboratory.
(6) Measurements for pH, temperature, turbidity and disinfectant residual may, under the direction of the direct responsible operator, be performed by any water supplier or their representative.
(7) All samples must be marked either: routine, repeat, check or investigative before submission of such samples to a certified laboratory. Routine, repeat, and check samples shall be considered compliance purpose samples.
(8) All sample results can be sent to the Division of Drinking Water either electronically or in hard copy form.
(9) Unless otherwise required by the Director, the effective dates on which required monitoring shall be initiated are identical to the dates published in 40 CFR 141 on July 1, 2001 by the Office of the Federal Register.
(10) Exemptions from monitoring requirements shall only be granted in accordance with R309-105-5.
R309-210-6. Lead and Copper Monitoring.
(1) General requirements.
(a) Applicability and effective dates
(i) The requirements of R309-210-6. unless otherwise indicated, apply to community water systems and non-transient non-community water systems (hereinafter referred to as water systems or systems).
(b) R309-210-6 establishes a treatment technique that includes requirements for corrosion control treatment, source water treatment, lead service line replacement, and public education. These requirements are triggered, in some cases, by lead and copper action levels measured in samples collected at consumers' taps.
(c) Corrosion control treatment requirements
(i) All water systems shall install and operate optimal corrosion control treatment. However, any water system that complies with the applicable corrosion control treatment requirements specified by the Director under R309-210-6(2) and R309-210-6(4)(a) shall be deemed in compliance with this treatment requirement.
(d) Source water treatment requirements
Any system exceeding the lead or copper action level shall implement all applicable source water treatment requirements specified by the Director under R309-210-6(4)(b).
(e) Lead service line replacement requirements
Any system exceeding the lead action level after implementation of applicable corrosion control and source water treatment requirements shall complete the lead service line replacement requirements contained in R309-210-6(4)(c).
