EXECUTIVE SUMMARY

Include a brief summary of this report.

1.0 INTRODUCTION

1.1 System Information:

Include the water system name, number, and address. Is it a new or an existing
water system? Is it a public or a non-public water system? If public, is it a
community, a non-transient/non-community, or a transient/non-community water
system? The first name of a new water system submitted to DDW will be the
name under which it will be tracked in the future. Please ensure, to the best of
your ability, that the name established for the water system remain the same. A
water system number will be assigned to that name.

1.2 Source Information:

Include the source name. What is the water right number? What is the latitude
and longitude of the point of diversion? Is it a new source or an existing source?
Is it a lake, river, or reservoir? Is this source already constructed? Include a
brief description of the source location, and the location of the point of diversion.

1.3 Designated Person - R309-605-5

Include the name, address, and phone number of the designated person. This
information must be included in each DWSP plan that is submitted to DDW.
Correspondence regarding this report and future correspondence will be directed
to the designated person.

2.0 THE DELINEATION REPORT - R309-605-7(3)

2
Three alternatives are available for providing the Delineation Report.

1. The Delineation Report may be obtained from the Division of
Drinking Water. The report will identify the four protection zones
described in R309-605-7(3)(b), and will contain a map or maps showing
the extent of the zones. A Delineation Report from DDW will become
section 2.0 of your DWSP plan.
2. Alternatively, the PWS may create and provide the
Delineation Report. Such a report must identify the four protection zones
described in R309-605-7(3)(b), and must contain a map or maps showing
the extent of the zones.
3. Alternatively, the PWS may define their own protection
zones based on their own criteria (R309-605-7(3)(c)), if they can
demonstrate that those zones are no less protective of their drinking water
source than the zones defined in R309-605-7(3)(b). Such a report must
identify the protection zones, must explain why the zones are protective of
the source, and must contain a map or maps showing the extent of the
zones. The entire watershed must be included in the delineation.

3.0 SUSCEPTIBILITY ANALYSIS AND DETERMINATION- R309-605-7(4)

3.1 Susceptibility Analysis - R309-605-7(4)(a)
3.1.1 Evaluate and describe the structural integrity of the intake. Is it adequate
to prevent inadvertent/accidental contamination? Does it comply, on a
pass-fail basis, with the minimum requirements for diversion structures
(R309-515-5(5))? These are
(a) Withdrawal of water from more than one level if quality varies with depth;
(b) Intake of lowest withdrawal elevation located at sufficient depth to be kept
submerged at the low water elevation of the reservoir;
(c) Separate facilities for release of less desirable water held in storage;
(d) Occasional cleaning of the inlet line;
(e) A diversion device capable of keeping large quantities of fish or debris from entering
an intake structure; and
(f) Suitable protection of pumps where used to transfer diverted water (refer to R309-540-5).

3.1.2 Evaluate and describe the sensitivity of the setting. Consider
physiographic and hydrogeologic factors, as well as man-made or natural
features that increase or decrease the likelihood of a contamination event.
Note that sensitivity is not related to the presence or absence of potential
contamination sources.
3.1.3 Assess the management and control of potential contamination sources
3.1.3(a) Inventory Potential Contamination Sources (PCS) -R309-
605-7(4)(a)(iii)(A)

3
DDW will provide you with a list of PCSs within your
watershed from the state’s geographic information system
databases. The list will identify the type of PCS, the
protection zone the PCS is located in, and the agency that
maintains records regarding the PCS, along with a contact
phone number. DDW will also provide maps identifying
the location of the various PCSs. DDW will also provide
generalized land use maps, which will allow you to assess
nonpoint source of potential contamination.
PWS Inventory: You are responsible for inventorying the
zones 1 to 3 (as applicable) and identifying any PCSs that
are not in the state’s database. You can rely on the
information provided by DDW for the rest of the
watershed. Obtain information regarding the name and
address of non-residential PCSs, the types of hazards
associated with a PCS, the zone the PCS is located in, and
the name and phone number of a contact person at the PCS.
Residential PCSs may be identified as generalized areas,
rather than listing individual residential lots. Related areas,
such as mining districts and the like, may also be grouped.
You will provide this information with your prioritized list
of PCSs in section 3.3.

3.1.3(b) Identify and assess controls - R309-605-7(4)(a)(iii)(B)
You are responsible for determining whether a PCS is
controlled or not, whether you identify it or DDW does.
The Surface Water User’s Guide contains criteria and
factors that must be evaluated when you determine whether
a PCS is controlled or not. Note that you must provide a
discussion of what control is in place, and the criteria and
factors that were evaluated. You may also wish to discuss
intrinsic hazards associated with the PCS, since one
currently considered controlled can become uncontrolled in
the future. The specific criteria, which must be addressed
in your report, can be found in the Surface Water User’s
Guide and in R309-605-7(4)(a)(iii)(B)(II).

3.2 Susceptibility Determination - R309-605-7(4)(b)

After evaluating the three factors in section 3.1, evaluate how susceptible your
source is to each PCS. You will probably want to weigh the three factors against
each other, although DDW will accept your best judgement regarding
susceptibility. It is possible that one factor may conspicuously outweigh the
others. As an example, if a PCS located near your intake is an uncontrolled
source of pathogens, you will probably want to consider your source susceptible
to that PCS, regardless of how sensitive the setting is, or what condition your

4
intake or diversion structure is in. You might decide that your source water is
not susceptible to any PCS that is considered controlled, although in some
instances, you may wish to consider your source water susceptible to a PCS that
is considered controlled but that contains extremely hazardous materials.

You may, at your discretion, want to use an analytical approach to making your
susceptibility determinations. This may especially be the case when you have
many PCSs to evaluate, and you want to be sure that your determinations are
uniform and unbiased. The Surface Water User’s Guide contains examples for
analytical approaches to susceptibility determinations, as well as a work sheet to
assist you in compiling information for your analysis.

3.3 Prioritized Potential Contamination Source Inventory - R309-605-7(4)(c)

At the conclusion of your susceptibility determination for all your PCSs, you will
have enough information to create a prioritized inventory of your PCSs. The
inventory will be arranged in an order emphasizing the relative susceptibility of
your source to each PCS. The inventory is a tool for you to use to allocate your
resources towards the PCSs that represent the highest threat to your drinking
water source.

When you create and present your inventory, include the following information
for each PCS:

Name and address of the PCS
Which protection zone the PCS is located in
The hazards associated with the PCS (chemical, biological, or
radiological)
Name and phone number of a contact at the facility, if applicable
Whether the PCS is controlled or not

A map or maps showing the locations of all the PCSs within your
watershed and protection zones must also be provided. You may use the
maps provided by DDW for this purpose. DDW will provide the GIS data
in electronic formats, upon request.

4.0 MANAGEMENT PLAN TO CONTROL EXISTING POTENTIAL CONTAMINATION
SOURCES R309-605-7(5):
Utah Administrative Code R309-605 requires that land management strategies be
planned for the three highest priority potential contamination sources that are not
adequately controlled. This section is intended to be a well thought out plan that will be
implemented by the PWS to control PCS hazards. It is not acceptable for the plan to
simply contain a list of land management strategies that are recommended by the
consultant. The PWS must concur with the land management strategies which are
included in this report and be willing to carry them out.

5
4.1 Discuss land management strategies to control the chemical, biological, and
radiological substances that have been identified at each of the three highest
priority Potential Contamination Sources. Land management strategies must be
planned to control the hazards identified at each PCS and be in accordance with
the authority and jurisdiction of the PWS. Land management strategies may be
regulatory and/or non-regulatory.

4.2 Include a discussion (if applicable) of the specific best management practices,
pollution prevention, and other risk reduction strategies that are proposed to control
potential contamination. Fact sheets regarding preventing pollution from many types of
PCSs are available from DDW, and can be downloaded from the DDW web site. 1 Links
to other examples of public education materials are also available on our site, including
videos, commercials, posters, public service radio messages, news releases, stencils for
storm drains, and the like.

4.3 If applicable, discuss existing management strategies that may already exist and
that will accomplish the goals of preventing the spread of contamination from
uncontrolled PCSs. Examples might include U.S. Forest Service Forest
Management plans, existing watershed protection plans, existing zoning under
other authorities, existing Water Quality Management Plans, and other existing
forms of protection. DDW has some information about some programs of this
type, although local land management authorities and soil conservation groups
would be good sources of up-to-date information. Provide a discussion regarding
how these programs, if any, meet your goals of protecting your drinking water
source.

5.0 MANAGEMENT PLAN TO CONTROL FUTURE POTENTIAL CONTAMINATION
SOURCES

If zoning ordinances are used, provide the following information: Discuss specific
sections of the zoning ordinance that are planned or that have been promulgated and
explain how they control or will control future PCSs.

If zoning ordinances are not used, provide the following information: Identify the plan to
contact PCSs individually as they move into protection zones, include them on the
inventory of PCSs, identify and assess current controls, and plan land management
strategies if they are not adequately controlled. This may include existing management
strategies such as those outlined in section 4.3.

6.0 IMPLEMENTATION SCHEDULE

1 Our new address is www.drinkingwater.utah.gov

6
The implementation schedule is a list of the land management strategies which have been
identified by the PWS for both existing and future PCSs with a beginning implementation
date for each one. Each management strategy must be addressed. You will be expected
to implement land management strategies as you specify in this schedule.

7.0 RESOURCE EVALUATION

The resource evaluation is a discussion of financial and other resources which will be
needed by the PWS to implement this DWSP Plan and a determination of how these
resources are to be acquired.

8.0 RECORD KEEPING

This section is included for the PWS to document changes as the plan is updated to show
current conditions in the protection zones and management areas. As the plan is
executed, you must document the implementation of each land management strategy as it
is implemented. This includes copies of ordinances, codes, permits, memoranda of
understanding, public education programs, training session agendas, minutes of meetings,
diary entries, memoranda for the file, etc.

9.0 CONTINGENCY PLAN

The Contingency Plan is only due once with the first Source Protection Plan submittal. If
you have an approved Contingency Plan from an earlier submittal, and if it includes your
surface water source, then it’s not necessary to do another one. If not, please provide a
plan that includes the following information:

Emergency Response: what will you do in the event of sudden contamination of your
water supply?

Rationing: How will you ration water to your customers?

Water Supply Decontamination: How will you decontaminate your source?

Source Development: Do you plan to develop alternate sources? If so, what are they?

10.0 PUBLIC NOTIFICATION

This section will include three subsections

10.1 Provide an example of the proposed public notification material. Examples of
acceptable public notices can be obtained from DDW. At a minimum, the public
notice must contain:

7
< A map showing the watershed area and general areas of concern,
including generalized locations of PCSs. (omit the map if you consider this
information to be sensitive).
< A general discussion of the topographic and geologic characteristics of
your watershed (generally, the factors you would use in determining how
sensitive your source area is).
< A discussion regarding the general categories of PCSs found in your
inventory, and how susceptible your source may be to them.
< A general discussion of the health concerns associated with the PCSs in
the watershed your source area
< A general discussion of your land management or other protection
strategies.
< Specific information regarding how any individual can obtain a copy of
your report(s).

DDW may request revisions of the public notification material if it does not
contain all the information required. Revisions may delay complete concurrence
with your DWSP plan.

10.2 Provide a discussion of the proposed methods for disseminating the information
to your customers. Make note of the all the people you may consider to be your
customers! You may wish to pay particular attention to locations with potentially
sensitive populations, such as hospitals and nursing homes. Depending on the
size of your system, a combination of methods may be desirable in order to assure
that your notification is successful.
10.3 Provide a discussion of the schedule for public notification. Public notification
must be done in a timely way, after your DWSP plan is completed.

Examples of acceptable public notices, and examples of methods for distributing the
information, are available from DDW.
