Dear Manuel Montano:
Subject: Public Drinking Water Requirements for Dinosaur NM - Dinosaur Quarry, UTAH24030
According to the Division of Drinking Water’s records, Dinosaur NM - Dinosaur Quarry is a
Non-Transient water system that serves a transient population of about 835, a residential
population of 10, and a non-transient population of 25 people.
This population change results in the following changes to your systems sampling and operator
certification requirements as follows:
Disinfection Byproducts (DBPs) Sampling
The water system is required to monitor for Disinfection Byproducts (DBP) given that it is a
non-transient non-community system that has chlorine in its water. The system is required to
collect two (2) DBP samples every year. Each sample must be a dual sample set of total
trihalomethanes (TTHMs) and haloacetic acids (HAA5). The next DBP samples must be
collected during the July 1 - September 30, 2025 monitoring period . For any questions
regarding the DBP rule contact Luke Treutel at [phone] or [e-mail].
DBP Sample Site Plan Development
The system must submit a DBP sample site plan with at least two sample sites to the Division
within 30 days of this letter. A sample site plan template with instructions has been enclosed.
For any questions regarding the DBP rule contact Luke Treutel at [phone] or
[e-mail].

Chlorine Residual Monitoring
All public water systems with chlorinated water must monitor chlorine residual levels in the
distribution system. As a result, the Dinosaur NM - Dinosaur Quarry water system must take a
minimum of three (3) chlorine residual samples per week at varying locations throughout
its distribution system in accordance with R309-105-10(1)(c). Distribution system chlorine
residuals must also be taken in conjunction with each routine total coliform sample in accordance
with R309-215-10(3). Distribution system chlorine residual monitoring results are submitted
quarterly and are due to the Division by the 10th day following the end of each reporting quarter
(i.e., January 10th, April 10th, July 10th and October 10th for quarterly reports). The chlorine
residuals should be submitted via the online form found at mrdl.utah.gov. For any questions
regarding the chlorine monitoring contact Luke Treutel at [phone] or [e-mail].
Chlorinator Operational Report Requirements
To demonstrate ongoing compliance with disinfection requirements, the water system must
complete monthly operational reports for each active chlorinator using a template approved by
the Division. The system must measure and record the chlorine level at the point of entry (POE)
to the distribution system (i.e. prior to any service connections) at least three times per week. The
system must also collect and record operational readings including the volume of water treated,
the type and amount of disinfectant used, and the rotometer or valve settings at least three times
per week. The POE residual data and the operational readings must be included in the
operational reports. Operational reports are submitted quarterly. The reports are due to the
Division by the 10th day following the end of each reporting month or quarter (i.e., January 10th,
April 10th, July 10th and October 10th for quarterly reports). The reports can be submitted by
uploading them to the chlorine residual reporting form found on MRDL.utah.gov. For any
questions regarding the chlorine monitoring contact Luke Treutel at [phone] or
[e-mail].
Operator Certification Requirements
The system is classified as a Non-Transient that serves a population of 870 persons. If the
system’s classification, complexity, or population changes, a certification may be required. This
requires a certified Distribution Grade I (D1) Direct Responsible Charge Operator (DRC) to
operate the system. According to our records, the system does not have an operator certified at
the level of the system registered as a Direct Responsible Charge (DRC). If the population
increases, a higher level of certification will be required.
The system has until August 15, 2025 , to come into compliance with the R309-300 Certification
Rules for Water Supply Operators. We have updated the System’s operator certification
requirements in the Division’s Improvement Priority System (IPS). Failure to comply would be a
significant deficiency and subject to demerit points.

Stage 2 Disinfectant Byproduct (DBP) Sampling Plan
In accordance with State of Utah Rule R309-210-10(3): Any Community (COM) or Non-Transient Non-Community
(NTNC) drinking water system that regularly applies a chemical disinfectant must develop and implement a DBP
monitoring plan. The system must maintain current version of the plan on file and submit a copy of 1) the monitoring
plan, 2) a schematic of the distribution system, and 3) the justification for site selection (IDSE water, modeling analysis,
etc.) to the Division of Drinking Water.

schedules are based on
population and source water
type. DBPs may be required
quarterly, annually, or every
three years. For a complete list of
possible schedules please see
associated DBP handout.
•One dual sample set must be taken at the
highest TTHM (trihalomethanes) sampling
site, at a location that represents
maximum residence time; typically in the
furthest reaches of your distribution
system, or where water is oldest.
This location is denoted as MR001.
•One dual sample set must be taken
at the highest HAA5 (haloacetic
acids) sampling site, at a location
that represents the average
residence time; typically located mid
distribution system
This location is denoted as MD001.
R309-210-10(3)(ii):
•Water system must identify which locations will be used for compliance monitoring
by alternating selection of locations representing high TTHM and high HAA5 levels
until the required number of compliance monitoring locations have been identified.
