Subject: Administrative Order: “Approved” Rating Determination and Secondary
Disinfection Requirements for East Grouse Creek Pipeline Water System
UTAH02010

Dear Julie Tanner,

The Division of Drinking Water would like to inform East Grouse Creek Pipeline Water of our
decision to change its status to the “Approved” rating in accordance with the Utah Drinking Water
Rules. Enclosed is the “Administrative Order: “Approved’ Rating Determination.”

While we are closing the Compliance Agreement Enforcement Order (CA/EO) the system must
continue to meet the secondary disinfection requirements outlined in the attached order. Please
note that these requirements remain in effect as long as the water system is in operation. For your
reference, we have also attached a handout explaining secondary disinfection in more detail.
Should you have any questions or need further assistance, please contact the Division of Drinking
Water environmental scientist, Luke Treutel at [phone] or [e-mail].

We appreciate the efforts you have taken to be in compliance with Utah’s Drinking Water Rules.
Those rules were adopted to ensure safe, reliable drinking water and to protect public health. My
staff and I stand ready to continue to assist you. Please contact us if there is anything we can do to
support you.

Sincerely,

Nathan Lunstad, Ph.D., P.E.

UTAH DEPARTMENT OF ENVIRONMENTAL QUALITY
DIVISION OF DRINKING WATER

In the Matter of:

East Grouse Creek Pipeline Water

ADMINISTRATIVE ORDER:
“APPROVED” RATING
DETERMINATION

Docket No. UTAH02010-2024

This ADMINISTRATIVE ORDER: “APPROVED” RATING DETERMINATION
(“Order”), relating to the East Grouse Creek Pipeline Water Company (the “System”), has been
issued by the Director of the Utah Division of Drinking Water (“Director”) based on the
authorities and findings provided herein. Notice of this Order is being provided to East Grouse
Creek Pipeline, a Corporation, as the “Supplier” who is legally responsible for the System.
STATUTORY AND REGULATORY AUTHORITY
1. In 1974, Congress enacted the federal Safe Drinking Water Act, codified at 42 U.S.C. §
300f et seq, as amended. 42 U.S.C. § 300g-2 allows states to achieve primary
enforcement responsibility after the Environmental Protection Agency (“EPA”) has
determined that the state has adopted and can implement a state program that is no less
stringent than the federal public drinking water program (“Primacy”).
2. The Utah legislature has enacted the Utah Safe Drinking Water Act, codified at Utah
Code § 19-4-101, with the intent of achieving Primacy.
3. Utah Code § 19-4-104 authorizes the Utah Drinking Water Board (the “Board”), among
other things, to make rules regulating public water systems in the state of Utah. Utah
Code § 19-4-104(1)(c)(vi) charges the Board to “meet the requirements of federal law
related or pertaining to drinking water.” The Board has promulgated the Utah Public
Drinking Water Rules, codified at Utah Administrative Code (“UAC”) R309.
4. In 1980, the EPA Administrator determined, in accordance with 40 C.F.R. § 142.11, that
the Utah public drinking water program met the federal requirements for Primacy. See
45 Fed. Reg. 6647 (January 29, 1980). In accordance with 40 C.F.R. § 142.17, the EPA
Administrator has reviewed, and continues to review annually, the Utah public drinking
water program to evaluate its continuing compliance with the requirements set forth in 40
C.F.R. Part 142.
5. The Board has defined public water systems under the Utah Public Drinking Water
Rules, UAC R309-110-4.
6. UAC R309-100-7 requires the Director to “assign a rating to each public water supply in
order to provide a concise indication of its condition and performance” in accordance

2

with R309-400. This rule is generally known as the Improvement Priority System(“IPS”)
rating system.
7. The IPS rating system “is a point system used by the division to evaluate a public water
system’s performance and compliance with the drinking water rules in Title 309,
Environmental Quality, Drinking Water.” UAC R309-400-3(1). Under the IPS rating
system, each public water system is assigned a rating “to characterize the water system’s
compliance with drinking water rules and overall operation and performance.” UAC
R309-400-3(2). The IPS rating system is “used by the division to assign compliance
ratings to public water systems and to prioritize enforcement action based on points
assessed for noncompliance with drinking water rules.” UAC R309-400-1(1).
8. UAC R309-400-4(1)(a)(ii) directs the Director to establish “the point thresholds for
assigning an Approved or Not Approved rating for each type of water system.” For
systems exceeding the point threshold, the Director may issue a “Not Approved” rating.
The thresholds are as follows: (i) for community water systems, 150 points; (ii) for non-
transient, non-community water systems, 120 points; and (iii) for non-community water
systems, 100 points.
9. UAC R309-400-4(4) allows the Director to assess points against public water systems
upon their failure to comply with Division directives and orders.
10. UAC R309-400-5(1)(b)(ii) allows the Director to rate any public water system as “Not
Approved” at any time if an immediate threat to public health exists.
11. UAC R309-400-5(1)(c) provides that a public water system may qualify for a “Corrective
Action” rating for its public water system “based on a current, written agreement with the
division to resolve underlying noncompliance according to a compliance schedule.”
12. Pursuant to Utah Code § 19-4-106(d), the Director may enforce rules promulgated by the
Board through the issuance of orders. See also UAC R309-100-8.
13. Utah Code § 19-4-107 provides that upon discovery of any violation of the Act or a rule
of the, the Director shall promptly notify the supplier of the violation, state the nature of
the violation, and issue an order requiring correction of that violation.
14. Utah Code § 19-4-109 provides that any person who violates the Act or a rule or order
made or issued pursuant to the Act may be subject to an administrative penalty of up to
$1,000 per day of violation or a civil penalty of up to $5,000 per day of violation.
15. The Director’s jurisdiction to issue this AO is based, in part, on Section 1447(a) of the
Safe Drinking Water Act, codified at 42 U.S.C. § 300j-6. The federal act provides that if
a state has achieved enforcement primacy, then federal agencies are subject to the
jurisdiction of the state agency with enforcement primacy. In directing federal facilities
to be subject to and to comply with all state requirements “in the same manner and to the
same extent as any [non-governmental entity,]” the explicit language of the federal act
demonstrates Congress’ intention that federal facilities be treated as any other public
water system covered by the federal act and, in turn, the state law (the Utah Safe

3

Drinking Water Act) and rules that implement the federal act. Thus, the Director is
required to assert jurisdiction over the Supplier in this matter in the same manner and to
the same extent as any non-governmental entity.
FINDINGS
Based on information in the Division’s administrative files, the Director makes the following
Findings for purposes of this Order:
1. The System is a public drinking water system within the meaning of the Utah Safe
Drinking Water Act and the Utah Public Drinking Water Rules.
2. The Supplier is the owner and/or operator of the System and is therefore legally
responsible for the System and for compliance with applicable laws, rules, and
regulations.
3. The System qualifies as a Community system under the Utah Public Drinking Water
Rules. The maximum number of points allowed for this type of system is 150.
4. The System is currently rated as “Corrective Action”.
5. For the reasons stated in the Master IPS Report attached hereto as Exhibit A, the System
has been assigned 85 points. This number is below the threshold provided in the IPS
Rule. The Master IPS Report is incorporated herein by this reference.
6. On September 28, 2020, the Supplier entered into a Corrective Action Enforcement Order
(“CA/EO”) relating to the System. As reflected in the Master IPS Report and Division
records, the Supplier has achieved compliance with the requirements in the CA/EO.
ORDER
Based on the foregoing Findings and good cause appearing, IT IS HEREBY ORDERED as
follows.
1. The System is hereby rated as “Approved” under the Utah Public Drinking Water Rules.
This approval is conditioned upon the Supplier continuing to provide the required
secondary disinfection requirements listed below.
2. The CA/EO dated September 28, 2020, is hereby closed.
Secondary Disinfection Requirements
