Subject: NOTICE OF VIOLATION – Failure to Monitor Distribution System Chlorine Residuals,
Holcim (US) Inc UTAH15002

Dear Cale Clark:

Our records indicate that Holcim (US) Inc is in violation of the State of Utah Public Drinking Water Rules
as follows:

As a system that disinfects or purchases disinfected water, Holcim (US) Inc is required to take a minimum
of 12 chlorine residuals per month in the distribution system per Rule R309-105-10(1)(c). Disinfectant
residual results for this system were not reported to the Division of Drinking Water (DDW) for the October
1st, 2024, to December 31st, 2024, compliance period.

In accordance with Rule R309-400, failure to take these samples and report them to DDW has resulted in
the addition of 15 Improvement Priority System (IPS) points to this water system’s IPS report for every
month that the Division did not receive chlorine residual data. These violations and associated points can
be resolved by collecting and reporting the required residual data in a future quarter.

Holcim (US) Inc staff must notify all the water system’s consumers of this violation within one year after
notification of this violation (see R309-220-7). Refer to the enclosed example of a public notice. A copy of
the notice sent to the system’s consumers must be forwarded to the Division of Drinking Water

([e-mail]) within ten days after issuing the notice (see R309-105-16(2). Failure to provide the
required public notification within one year will result in the addition of five points to this system’s IPS
report.

If the distribution system chlorine residual sampling has been completed for the compliance period above,
please contact the Division to resolve this issue. Attached is an informational sheet that describes how
water system staff can submit chlorine residual data online. Please contact Luke Treutel at [phone]
or [e-mail] if you have any questions or need assistance regarding this notice. Thank you for your
efforts to maintain safe drinking water.

Sincerely,
Mark Berger
Monitoring and Standards Section Manager

Instructions for Monitoring Violations Annual Notice – Chemical Monitoring (Tier 3)

Template on Reverse

Since most monitoring violations are included in Tier 3, you must provide public notice to persons served
within one year after you learn of the violation (R309-220-7(2)). Multiple monitoring violations can be
serious, check with the Division of Drinking Water (801-536-4200) to make sure you meet the public
notification requirements.

Community systems must use one of the following (R309-220-7(3)(a)):

 Hand or direct delivery
 Mail, as a separate notice or included with the bill

Non-community systems must use one of the following (R309-220-7(3)(b)):

 Posting in conspicuous locations
 Hand delivery
 Mail

In addition, both community and non-community systems must use another method reasonably
calculated to reach others if they would not be reached by the first method (R309-220-7(3)). Such
methods could include newspapers, e-mail, or delivery to community organizations. If you post the
notice, it must remain posted until the violation is resolved. If the violation has been resolved, you must
post the notice for at least one week (R309-220-7(2)). If you mail, post, or hand deliver, print your notice
on letterhead, if available.

The notice on the reverse is appropriate for insertion in an annual notice or the CCR, as long as public
notification timing and delivery requirements are met (R309-220-7(4)). You may need to modify the
template for a notice for individual monitoring violations. This example presents violations in a table;
however, you may write out an explanation for each violation if you wish. For any monitoring violation for
volatile organic compounds (VOCs) or other groups, you may list the group name in the table, but you
must provide the name of every chemical in the group on the notice, e.g., in a footnote.

You may need to modify the notice if you had any monitoring violations for which monitoring later showed
a maximum contaminant level or other violation. In such cases, you should refer to the public notice you
issued at that time.

Include in your notice the standard language for monitoring and testing procedure violations in italics
(R309-220-8(4)(b)). If you modify the notice, you may not alter this mandatory language.

Corrective Actions

In your notice, describe corrective actions you took or are taking. Listed below are some steps commonly
taken by water systems with monitoring violations. Choose the appropriate language, or develop your
own:

 We have since taken the required samples, as described in the last column of the table above.
The samples showed we are meeting drinking water standards.
 We have since taken the required samples, as described in the last column of the table above.
The sample for [contaminant] exceeded the limit. [Describe corrective action; use information
from public notice prepared for violating the limit.]
 We plan to take the required samples soon, as described in the last column of the table above.

After Issuing the Notice

Make sure to send the Division of Drinking Water (PO Box 144830, SLC, UT 84114-4830) a copy of each
type of notice and a certification that you have met all the public notice requirements within ten days after
issuing the notice (R309-105-16(3)).

IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER
Monitoring Requirements Not Met for [System]

Our water system violated several drinking water standards over the past year. Even though
these were not emergencies, as our customers, you have a right to know what happened and
what we did to correct these situations.

We are required to monitor your drinking water for specific contaminants on a regular basis.
Results of regular monitoring are an indicator of whether or not our drinking water meets health
standards. During [compliance period] we ['did not monitor or test' or 'did not complete all
monitoring or testing'] for [contaminant(s)] and therefore cannot be sure of the quality of our
drinking water during that time.

What should I do?

There is nothing you need to do at this time.

The table below lists the contaminant(s) we did not properly test for during the last year, how
often we are supposed to sample for this contaminant and how many samples we are supposed
to take, how many samples we took, when samples should have been taken, and the date on
which follow-up samples were (or will be) taken.

DISTRIBUTION SYSTEM
CHLORINE RESIDUALS &
CHLORINATOR REPORTS

Quarterly Treatment Reports are required to be sent to the
Division of Drinking Water (DDW), per R309-105-10(1).
The quarterly report has three main components:
1.Disinfection byproduct sample results
2.Chlorine residual results from the distribution
system
3.Operational data (rotameter/pump settings,
volume of water treated, chlorine residuals at the
point of entry, etc.)

Ask your lab to submit the
data electronically
Or email to
[e-mail]
Submit distribution system chlorine
residual averages online at
MRDL.utah.gov
Download Operational Report
and submit to MRDL.utah.gov form at the same time as chlorine residual summary
** Systems that purchase chlorinated water but do not add additional disinfectant do not need to report operational data.
Failure to submit a quarterly report will result in a violation and 15 IPS points for each month of
missing data. (R309-400-3)
Applies
to:
Water systems that chlorinate
or purchase chlorinated water
How many residuals should I be taking?
All disinfecting systems, or systems purchasing
disinfected water, must sample a minimum of 3
chlorine residuals within the distribution
system per week, at least 12 per month.
Each time you sample for coliform bacteria you
should also be taking a chlorine residual test. The
coliform sample residuals can count towards your
system’s total distribution residual requirement.
When do I submit quarterly reports? 
Within 10 days after the end of
each quarter
