deficient with respect to any provision of the specifications.
C. The CONTRACTOR shall make all repairs and replacements promptly upon receipt of written
orders for the same from the OWNER. If the CONTRACTOR fails to make repairs and
replacements within 5 days upon notification, the OWNER may contract with others for
performance of the work and the CONTRACT and his surety shall be liable to the OWNER for
the cost thereof.
9.3 Wherever in these Specifications the word "approved" appears, it shall be understood to
mean "as approved by the OWNER or authorized representative." Where approvals are
required, the CONTRACTOR shall keep a written signed record of those approvals and report
such approvals in the daily logs.

STOCKTON TOWN SPECIAL CONDITIONS FOR DRILLING
OLD TANK WELL PROJECT PAGE 02 32 30 - 10
9.7 SUBSTITUTES AND “OR EQUAL” ITEMS
A. Whenever an item of material or equipment is specified or described in the Contract
documents by using the name of a proprietary item or the name of a particular Supplier, the
specification or description is intended to establish the type, function, and quality required.
Whenever one manufacturer or supplier of an item of material or equipment is mentioned in
the Specifications of Divisions 1 and 2, add the words “or equal’ after the listed manufacturer
or supplier, unless the manufacturer’s name is followed by words reading “no or-equal or
substitute products will be accepted” or similar wording. Unless the specification or
description contains or is followed by words reading that no like, equivalent or “or-equal”
item or no substitution is permitted, other items of material or equipment or material or
equipment of other Suppliers may be accepted by the ENGINEER under the following
circumstances:
1. “Or-Equal”: If in the ENGINEER’s sole discretion an item of material or equipment
proposed by CONTRACTOR is equivalent to or better than the product named in the
form, function, performance, reliability, quality, features, materials of construction,
operation and maintenance cost, static and dynamic loads, general dimensional
configuration, size, weight, and appearance to that named and sufficiently similar so
that no change in related work will be required, it may be considered by ENGINEER
as an “or-equal” item, in which case review and approval of the proposed item may,
in ENGINEER’s sole discretion, be accomplished without compliance with some or all
of the requirements for acceptance of proposed substitute items.
2. Substitute Items: If in ENGINEER’s sole discretion an item of material or equipment
proposed by CONTRACTOR does not qualify as an “or-equal” item, it will be
considered a proposed substitute item. CONTRACTOR shall submit sufficient
information as provided below to allow ENGINEER to determine that the item of
material or equipment proposed is essentially equivalent to that named and an
acceptable substitute thereof. The procedure for review by ENGINEER will include
the following and as ENGINEER may decide is appropriate under the circumstances.
Request for review of proposed substitute items of material or equipment will not be
accepted by ENGINEER from anyone other than CONTRACTOR. If CONTRACTOR
wishes to furnish or use a substitute item of material or equipment, CONTRACTOR
shall first make written application to the ENGINEER for acceptance thereof,
certifying that the proposed substitute will perform adequately the functions and
achieve the results called for by the general design, be similar in substance to that
specified and be suited to the same use as that specified. The application will state
the extent, if any, to which the evaluation and acceptance of the proposed substitute
will prejudice CONTRACTOR’s achievement of Substantial Completion on time,
whether or not acceptance of the substitute for use in the work will require change in
any of the Contract Documents (or in the provisions of any other direct contract with
OWNER for work on the Project) to adapt the design to the proposed substitute and
whether or not incorporation or use of the substitute in connection with the work is
subject to payment of any license fee or royalty. All variations of the proposed
substitute from that specified will be identified in the application and available
maintenance, repair and replacement service indicated. The application will also
contain an itemized estimate of all costs or credits that will result directly or
indirectly from acceptance of such substitute, including costs of redesign and claims
of other contractors affected by the resulting change, all of which will be considered

BC&A
STOCKTON TOWN SPECIAL CONDITIONS FOR DRILLING
OLD TANK WELL PROJECT PAGE 02 32 30 - 11
by ENGINEER in evaluating the proposed substitute. ENGINEER may require
CONTRACTOR to furnish additional data about the proposed substitute.
3. CONTRACTOR’s expense: All data to be provided by CONTRACTOR in support of any
proposed “or-equal” or substitute item will be at CONTRACTOR’s expense.
B. ENGINEER will be allowed a reasonable time within which to evaluate each proposal or
submittal made pursuant to paragraphs 9.7.A.1, 9.7.A.2, and 9.7.A.3. ENGINEER will be the
sole judge of acceptability. No “or-equal” will be ordered, installed, or utilized without
ENGINEER’s prior written acceptance which will be evidenced by a Change Order or an
approved Shop Drawing. No substitute will be ordered, installed, or utilized without
ENGINEER’s prior written acceptance which will be evidenced by a Change Order. OWNER
may require CONTRACTOR to furnish at CONTRACTOR’s expense a special performance
guarantee or other surety with respect to any “or-equal” or substitute. ENGINEER will record
time required by ENGINEER, and/or other consultants in evaluating substitutes proposed or
submitted by CONTRACTOR in making changes in the Contract Documents (or in the
provisions of any other direct contract with OWNER for work on the Project) occasioned
thereby. Whether or not ENGINEER accepts a substitute item so proposed or submitted by
CONTRACTOR, CONTRACTOR shall reimburse OWNER for charges of ENGINEER and/or
consultants for evaluating each proposed substitute item.
C. Proposal by CONTRACTOR to provide “or-equal” or substitute materials or equipment shall
be submitted within a maximum of thirty-five (35) days of Contract award. Further,
CONTRACTOR agrees that these proposals create a risk that the materials or equipment may
not meet the specified functional and performance requirements and create a risk associated
with potentially unproven products. Risk arises due to unknowns relating to reliability and
durability of product, and responsiveness and support capability of supplier. Limited time is
available to review and accept an “or-equal” or substituted item during construction (as
compared to time available during design). CONTRACTOR agrees, therefore, that acceptance
of an “or-equal” or substitute item does not relieve CONTRACTOR from responsibility for
meeting specified functional and performance requirements. CONTRACTOR shall bear all
costs necessary to ensure the “or-equal” or substitute item meets specified functional and
performance requirements and operates trouble free.
PART 10 - SUBMITTALS DURING CONSTRUCTION
10.1 GENERAL
A. Requirements in this section are in addition to any specific submittal requirements as set
forth in Specification sections of these Contract Documents.
B. Review, acceptance, or approval of substitutions, schedules, Shop Drawings, lists of materials,

I. OWNER's review will be only for conformance with the design concept of the project and for
compliance with the information given in the Contract Documents and shall not extend to
means, methods, techniques, sequences, or procedures of construction (except where a
specific means, method, technique, sequence, or procedure of construction is indicated in or
required by the Contract Documents) or to safety precautions or programs incident thereto.
The review of a separate item as such will not indicate review of the assembly in which the
item functions.
J. ENGINEER 's review of submittals shall not relieve CONTRACTOR from responsibility for any
variation from the requirements of the Contract Documents unless CONTRACTOR has in
writing called OWNER's attention to each such variation at the time of submission and
OWNER has given written approval of each such variation by a specific written notation
thereof incorporated in or accompanying the shop drawing or sample approval; nor will any
approval by OWNER relieve CONTRACTOR from responsibility for errors or omissions in the
Shop Drawings or from responsibility for having complied with the provisions herein.
K. Where a shop drawing or sample is required by the Specifications, any related work
performed prior to ENGINEER's review and approval of the pertinent submission shall be the
sole expense and responsibility of CONTRACTOR.

D. During the constant-rate drawdown test the discharge rate from the pump shall be
controlled by both a valve and engine throttle. The discharge rate shall be controlled and
maintained at approximately the desired discharge with an accuracy of at least plus or
minus 5 percent. Pump discharge rates shall be measured with an instantaneous and
totalizing flow meter and orifice plate/manometer apparatus, as approved by the
ENGINEER.
E. Whenever continuous pumping at a uniform rate has been specified, failure of pump
operation shall require that the test be aborted and further testing suspended until the
water level in the pumped well has recovered to its original level. For the purposes of this
section, recovery shall be considered "complete" after the well has been allowed to rest for
a period at least equal to the elapsed pumping time of the aborted test, with the exception
that if any three successive water level measurements spaced at least 20 minutes apart
show no further rise in the water level in the pumped well, the test may be resumed at the
direction of the ENGINEER.
F. Any test that does not meet the duration requirement specified above, or that is initiated
too soon after an aborted test as defined above, shall be declared invalid, and the
CONTRACTOR will not be paid for the invalid test.
G. The CONTRACTOR shall provide all information to the ENGINEER regarding the type of
pumping equipment used, including engines, drive components, bowls, lines, and shafts.
The CONTRACTOR shall keep records of the operation of equipment during the tests
including engine rpm and horsepower, fuel use, and other essential information that will be
useful in designing a pump system.
H. During the constant rate pump test, the CONTRACTOR will provide assistance and access to
the ENGINEER for collecting water quality samples from the pump discharge water.
Approximately one water quality sample may be taken for the full suite of Safe Drinking
Water Act parameters near the end of the test.
I. After completion of water level monitoring, and after the pump has been removed from the
well, the CONTRACTOR shall remove all sand and debris that has accumulated in the bottom
of the well.
3.2 WATER LEVEL MEASUREMENT
A. Equipment needed to adequately monitor water level before, during, and after the constant-
rate pumping test include:
1. Electronic water level sounder (Solinst or equal) of sufficient length to monitor
water level.
2. Pressure transducer (In-Situ Inc. PXD-261, Level TROLL, or equal) to be placed in
the water level sounding tube of sufficient length to remain below the water table
during the entire duration of the pumping test.

3. Data logger (Virtual HERMIT, Level TROLL, or equal) for the purpose of obtaining
frequent and automated water level readings during the pump test.
B. Hand (manual) measurements of depth to water shall be performed before and after the
test using an electronic water level sounder to test the accuracy of the transducer. Manual
measurements will also be performed during the pumping test at a frequency approved by
the ENGINEER. The data logger and transducer shall be set-up and started prior to the
pump test so that the initial static water level is determined and recorded. Several
measurements shall be taken over the 24-hour period before the test. The data logger will
be set up to recorded water level measurements at a logarithmic time frequency as the
pumping is started. At a minimum, water level measurements will be collected in
accordance with the following table:

Time Since Pumping
Started/Stopped
(minutes)
Time Interval for
Drawdown Measurements
(minutes)
0-10 0.5-1
10-15 1

60-300 30
300-End of test (minimum 24 hours) 60 (1 hour)

C. Flow rates shall be measured accurately and recorded at the same time interval as
drawdown data.
D. After pumping is terminated (24-hour minimum test duration) recovery shall be monitored
for at least 6 hours or until 85 percent recovery is completed.

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 4
Guidance: Approval for non-ferrous well casing will be determined considering well
depth, formations, temperatures, corrosion potential, well seal material, and other
pertinent information.
(d) Disposal of Cuttings.
Cuttings and waste from well drilling operations shall not be discharged into a
waterway, lake, or reservoir. The rules of the Utah Division of Water Quality must be
observed with respect to these discharges.

(e) Packers.
Packers, if used, shall be of material that will not impart taste, odor, toxic substances, or
bacterial contamination to the well water. Lead or partial lead packers are specifically
prohibited.
(f) Screens.
The use of well screens is recommended where appropriate and, if used, they shall:
(i) be constructed of material resistant to damage by chemical action of groundwater or
cleaning operations;
(ii) have size of openings based on sieve analysis of formations or gravel pack materials;
(iii) have sufficient diameter to provide adequate specific capacity and low aperture
entrance velocities;
Guidance: Usually the entrance velocities should not exceed 0.1 fps.
(iv) be installed so that the operating water level remains above the screen under all
pumping conditions; and,
(v) be provided with a bottom plate or wash-down bottom fitting of the same material as
the screen.
(g) Plumbness and Alignment Requirements.
Every well shall be tested for plumbness and vertical alignment in accordance with AWWA
Standard A100. Plans and specifications submitted for review shall:
(i) have the test method and allowable tolerances clearly stated in the specifications; and,
(ii) clearly indicate any options the design engineer may have if the well fails to meet the
requirements. Generally, wells may be accepted if the misalignment does not interfere with
the installation or operation of the pump or uniform placement of grout.
(h) Casing Perforations.
The placement of perforations in the well casing shall:
(i) be located, as far as practical, to permit the uniform collection of water around the
circumference of the well casing; and,
(ii) be of dimensions and size to restrain the water bearing soils from entrance into the well.
(i) Well Sealing Techniques and Requirements.
For all public drinking water wells, the annulus between the outermost well casing and the
borehole wall shall be sealed with grout to a depth of at least 100 feet below the ground
surface unless an "exception" is issued by the Director (see R309-500-4(1)). If more than
one casing is used, including a conductor casing, the annulus between the outermost casing
and the next inner casing shall be sealed with grout (meeting the sealing materials
requirements of R309-515-6(i)(ii) herein) or with a water tight steel ring having a thickness
equal to that of the permanent well casing and continuously welded to both casings. If a
public drinking water well will be equipped with a pitless adapter or unit, a well seal shall
be installed to a minimum depth of 110 feet to take into account the top 10 feet of
compromised seal interval.
Guidance: This is required in order to prevent the seepage of undesirable surface or
shallow ground water along the casing into the water bearing aquifer. The Division

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 5
of Water Rights Administrative Rules for Water Wells Rule R655-4-11.7.5, Pitless
Adapters/Units states, “A cement grout seal shall not be allowed within the pitless
unit or pitless adapter sealing interval. The pitless adapter or unit sealing interval
shall be sealed with unhydrated bentonite. The pitless adapter or unit, including the
cap or cover, pitless case and other attachments, shall be designed and constructed
to be watertight to prevent the entrance of contaminants into the well from surface
or near-surface sources.” Therefore, a cement seal should not be used in the future
pitless interval as a cement seal would need to be chipped and broken away from the
casing when the pitless area is excavated and installed which could lead to casing
damage. A bentonite seal must be used in the future pitless interval.
The following shall apply to all drinking water wells:
(i) Consideration During Well Construction.
(A) Sufficient annular opening shall be provided to permit a minimum of two inches
of grout between the outermost permanent casing and the drilled hole, taking into
consideration any joint couplings.
(B) The casing(s) must be placed to permit unobstructed flow and uniform thickness
of grout.
Guidance: For the purpose of determining the dimension of the annular opening
between the drilled hole and or any carrier casing or permanent casing which
may be used, the nominal pipe dimension of casing or hole can be used.
Centralizers, casing spacers, or welded guides are recommended to center the
casing and to provide uniform grout thickness.
(ii) Sealing Materials.
(A) Neat Cement Grout.
Cement, conforming to ASTM Standard C150, and water, with no more than six
gallons of water per sack of cement, shall be used for two-inch openings. Additives
may be used to increase fluidity subject to approval by the Director.
(B) Concrete Grout.
Equal parts of cement conforming to ASTM Standard C150, and sand, with not more
than six gallons of water per sack of cement, may be used for openings larger than
two inches.
(C) Clay Seal.
Where an annular opening greater than six inches is available, a seal of swelling
bentonite meeting the requirements of R655-4-11.4.2 may be used when approved
by the Director.
(iii) Application.
(A) When the annular opening is less than four inches, grout shall be installed under
pressure, by means of a positive displacement grout pump, from the bottom of the
annular opening to be filled.
(B) When the annular opening is four or more inches and 100 feet or less in depth,
and concrete grout is used, it may be placed by gravity through a grout pipe installed
to the bottom of the annular opening in one continuous operation until the annular
opening is filled.
(C) All temporary construction casings shall be removed prior to or during the well
sealing operation. Any exceptions shall be approved by the State Engineer’s Office,
and evidence of State Engineer’s Office’s approval shall be submitted to the Director
(see R655-4-11.4.3.1 for conditions concerning leaving temporary surface casing in
place). A temporary construction casing is a casing not intended to be part of the
permanent well.

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 6
(D) When a "well in a protected aquifer" classification is desired, the grout seal shall
extend from the ground surface down to at least 100 feet below the surface, and
through the protective clay layer (see R309-600-6(1)(x)).
(E) After cement grouting is applied, work on the well shall be discontinued until the
cement or concrete grout has properly set, usually a period of 72 hours.
Guidance: “Public Water Supply Well Grouting Requirements and Procedures” is
available on the Division’s website as additional information for grout
placement.
(j) Water Entered Into Well During Construction.
Any water entering a well during construction shall not be contaminated and should be
obtained from a chlorinated municipal system. Where this is not possible, the water must be
treated to produce a 100 mg/l free chlorine residual in accordance with R655-4-11.6.5.
(k) Gravel Pack Wells.
The following shall apply to gravel packed wells:
(i) the gravel pack material shall be of well-rounded particles, at least 90 percent
siliceous material, no more than five percent acid solubility, smooth and uniform, free of
foreign material, properly sized, washed, and then disinfected immediately prior to or
during placement;
(ii) the gravel pack shall be placed in one uniform continuous operation;
(iii) refill pipes, when used, shall be Schedule 40 steel pipe incorporated within the pump
foundation and terminated with screwed or welded caps at least 12 inches above the pump
house floor or concrete apron;
(iv) refill pipes located in the grouted annular opening shall be surrounded by a minimum
of 1.5 inches of grout;
(v) protection shall be provided to prevent leakage of grout into the gravel pack or screen;
and,
(vi) any casings not withdrawn entirely shall meet requirements of R309-515-6(6)(b) or
R309-515-6(6)(c).

R309-515-6 (7) Well Development
Well Development
(a) Every well shall be developed to remove the native silts and clays, drilling mud or finer
fraction of the gravel pack.
(b) Development should continue until the maximum specific capacity is obtained from the
completed well.
(c) Where chemical conditioning is required, the specifications shall include provisions for
the method, equipment, chemicals, testing for residual chemicals, and disposal of waste and
inhibitors.
(d) Where blasting procedures may be used the specifications shall include the provisions
for blasting and cleaning. Special attention shall be given to assure that the grouting and
casing are not damaged by the blasting.

R309-515-6 (8) Well Capping
Capping Requirements.
(a) The well shall be securely capped in accordance with R655-4-14.1 until permanent
equipment can be installed.
(b) At all times during the progress of work the contractor shall provide protection to
prevent tampering with the well or entrance of foreign materials.

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 7
Guidance: A welded metal plate or a threaded cap is the preferred method for capping a
completed well until permanent equipment is installed.

R309-515-6 (9) Well Abandonment
Well Abandonment.
(a) Test wells and groundwater sources which are to be permanently abandoned shall be
abandoned in accordance with R655-4-14.
(b) Wells to be abandoned shall be sealed to prevent undesirable exchange of water from
one aquifer to another. Preference shall be given to using a neat cement grout. Where fill
materials are used, which are other than cement grout or concrete, they shall be disinfected
and free of foreign materials. When an abandoned well is filled with cement-grout or
concrete, these materials shall be applied to the well hole through a pipe, tremie, or bailer.

R309-515-6 (10) Well Assessment
Well Assessment.
(a) Step Drawdown Test.
Preliminary to the constant-rate test required below, it is recommended that a step-
drawdown test (uniform increases in pumping rates over uniform time intervals with single
drawdown measurements taken at the end of the intervals) be conducted to determine the
maximum pumping rate for the desired intake setting.
(b) Constant-Rate Test.
A "constant-rate" yield and drawdown test shall:
(i) be performed on every production well after well development and prior to placement
of the permanent pump,
(ii) have the test methods clearly indicated in the specifications,
(iii) have a test pump with sufficient capacity that when pumped against the maximum

discharge rate,
(iv) provide for continuous pumping for at least 24 hours or until stabilized drawdown
has continued for at least six hours when test pumped at a "constant-rate" equal to 1.5
times the desired design discharge rate,
(v) provide the following data:
(A) capacity vs. head characteristics for the test pump (manufacturer's pump curve),
(B) static water level (in feet to the nearest tenth, as measured from an identified
datum; usually the top of casing),
(C) depth of test pump intake,
(D) time and date of starting and ending test(s),
Guidance: It is recommended to monitor any existing wells in the area during the pump
test to perform a more useful aquifer test and determine if there will be interference
from other wells.
(vi) For the "constant-rate" test provide the following at time intervals sufficient for at
least ten essentially uniform intervals for each log cycle of the graphic evaluation
required below:
(A) record the time since starting test (in minutes),
(B) record the actual pumping rate,
(C) record the pumping water level (in feet to the nearest tenth, as measured from
the same datum used for the static water level),
(D) record the drawdown (pumping water level minus static water level in feet to
the nearest tenth),

(E) provide graphic evaluation on semi logarithmic graph paper by plotting the
drawdown measurements on the arithmetic scale at locations corresponding to time
since starting test on the logarithmic scale, and
(vii) Immediately after termination of the constant-rate test, and for a period of time
until there are no changes in depth to water level measurements for at least six hours,
record the following at time intervals similar to those used during the constant-rate
pump test:
(A) time since stopping pump test (in minutes),
depth to water level (in feet to the nearest tenth, as measured from the same datum
used for the pumping water level).
(c) Safe Yield. If the aquifer drawdown test data show that the drawdown has stabilized, the
Director will consider 2/3 of the pumping rate used in the constant-rate test as the safe yield of
the well. The safe yield is used to determine the number of permanent residential connections
or ERCs that a well source can support.

4.1 Authorization to Drill
The well driller shall make certain that a valid authorization or approval to drill exists before engaging
in regulated well drilling activity. Authorization to drill shall consist of a valid 'start card' based on any
of the approvals listed below. Items 4.1.1 through 4.1.12 allow the applicant to contract with a well
driller to drill, construct, deepen, replace, repair, renovate, or abandon exactly one well at each location
listed on the start card or approval form. The drilling of multiple borings/wells at an approved
location/point of diversion is not allowed without authorization from the state engineer's office. Most
start cards list the date when the authorization to drill expires. If the expiration date has passed, the
start card and authorization to engage in regulated drilling activity is no longer valid. If there is no
expiration date on the start card, the driller must contact the state engineer's office to determine if the
authorization to drill is still valid. When the work is completed, the permission to drill is terminated.
Preauthorization or pre-approval of pump installation/repair work, well cleaning, development, testing,
and disinfection is not required. A well renovation permit is required if an existing well is to be modified
by activities such as deepening, casing/seal/gravel pack repair/renovation, liner installation, pitless
adapter/unit installation, and perforating/screen installation. A well renovation permit is not required
if the well is not modified by activities such as cleaning, development, testing, disinfection, and pump
work.
4.1.1 An approved application to appropriate.
4.1.2 A provisional well approval letter (also known as a Rush Letter Approval).
An approved provisional well letter grants authority to drill but allows only enough water
to be diverted to determine the characteristics of an aquifer or the existence of a useable
groundwater source.
4.1.3 An approved permanent change application.

Section R655-14 UAC)

R655-4-10 General Requirements
10.1 Standards
10.1.1 In some locations, the compliance with the following minimum standards will not
result in a well being free from pollution or from being a source of subsurface leakage,
waste, or contamination of the groundwater resource. Since it is impractical to attempt to
prepare standards for every conceivable situation, the well driller or pump installer shall
judge when to construct or otherwise perform work on wells under more stringent
standards when such precautions are necessary to protect the groundwater supply and
those using the well in question. Other state and local regulations pertaining to well
drilling and construction, groundwater protection, isolation distances (setbacks) from
potential contamination sources and/or other structures/boundaries, and water
quality/testing regulations may exist that are either more stringent than these rules or that
specifically apply to a given situation. It is the licensee's responsibility to understand and
apply other federal, state, and local regulations as applicable.

R655-4-10.2 Well Site Locations
10.2 Well Site Locations.
10.2.1 Well site locations are described by course and distance from outside section
corners or quarter corners (based on a Section/Township/Range Cadastral System) and
by the Universal Transverse Mercator (UTM) coordinate system (NAD83 Map Datum) on
all state engineer authorizations to drill (Start Cards). However, the licensee should also be
familiar with local zoning ordinances, or county boards of health requirements which may
limit or restrict the actual well location and construction in relationship to
property/structure boundaries and existing or proposed concentrated sources of pollution
or contamination such as septic tanks, drain fields, sewer lines, stock corrals, feed lots, etc.
The licensee should also be familiar with the Utah Underground Facilities Act (Title 54,
Chapter 8a of the Utah Code Annotated 1953 as amended) which requires subsurface
excavators (including well drilling) to notify operators of underground utilities prior to any
subsurface excavation. Information on this requirement can be found by calling Blue
Stakes Utility Notification Center at [phone].
10.2.2 Regulated wells shall be drilled at the approved location as defined on the valid
start card. The driller shall check the drilling location to see if it matches the state-
approved location listed on the Driller's Start Card.

R655-4-10.3 Unusual Conditions

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 16
10.3.1 If unusual conditions occur at a well site and compliance with these rules and standards
will not result in a satisfactory well or protection to the groundwater supply, a licensed water
well driller or pump installer shall request that special standards be prescribed for a particular
well (variance request). The request for special standards shall be in writing and shall set forth
the location of the well, the name of the owner, the unusual conditions existing at the well site,
the reasons and justification that compliance with the rules and minimum standards will not
result in a satisfactory well, and the proposed standards that the licensee believes will be more
adequate for this particular well. If the state engineer finds that the proposed changes are in
the best interest of the public, the state engineer will approve the proposed changes by
assigning special standards for the particular well under consideration. At the Division's
discretion, the licensee applying for the variance may be required to provide additional
technical information justifying the variance. The variance request will be evaluated, and a
response will be given within fourteen days. In a public health emergency or other exceptional
circumstance, verbal notification for a variance may be given. An emergency usually consists of
a well failure resulting in a dry well or an unusable well. Driller convenience does not
constitute an emergency.

R655-4-11 Well Drilling and Construction Requirements

R655-4-11.2.4 Plastic and Other Non-metallic Casing
11.2.4 Plastic and Other Non-metallic Casing.
11.2.4.1 Materials. PVC well casing and screen may be installed in Utah upon obtaining
permission of the well owner. Other types of non-metallic casing or screen must be approved
by the state engineer prior to installation. Plastic well casing and screen shall be manufactured
and installed to conform with The American National Standards Institute (ANSI) or the
American Society for Testing and Materials (ASTM) Standard F 480 (most recent version),
which are incorporated by reference to these rules. Casing and screen meeting this standard is
normally marked "WELL CASING" and with the ANSI/ASTM designation "F 480-, SDR-17 (or
13.5, 21, etc.)". All plastic casing and screen for use in potable water supplies shall be
manufactured to be acceptable to the American National Standards Institute/National
Sanitation Foundation (NSF) standard 61. Other types of plastic casings and screens may be
installed upon manufacturers certification that such casing meets or exceeds the above
described ASTM/SDR specification or ANSI/NSF approval and upon state engineer approval.
11.2.4.2 Minimum Wall Thickness and Depth Requirements. PVC well casing and screen with
a nominal diameter equal to or less than four (4) inches and for non-production well purposes
shall meet the minimum wall thickness required under ASTM Standard F480-95 SDR 21 or a
Schedule 40 designation. PVC well casing and screen use for water production well purposes
with a nominal diameter equal to or less than four (4) inches shall meet the minimum wall
thickness required under ASTM Standard F480-95 SDR 17 or a Schedule 80 designation. PVC
well casing and screen with a nominal diameter greater than four (4) inches shall meet the
minimum wall thickness required under ASTM Standard F480 (most recent version) SDR 17 or
a Schedule 80 designation. Additionally, caution should be used whenever other than factory
slots or perforations are added to PVC well casing. The installation of hand cut slots or
perforations significantly reduces the collapse strength tolerances of unaltered casings. The
depth at which plastic casing and screen is placed in a well shall conform to the minimum
requirements and restrictions as outlined in ASTM Standard F-480 (most recent version) and
to PVC casing manufacturer recommendations. Liner pipe does not need to meet these wall
thickness requirements if it is placed inside of a casing that does meet these wall thickness
requirements.
11.2.4.3 Fiberglass Casing. Fiberglass reinforced plastic well casings and screens may be
installed in wells upon obtaining permission of the well owner. All fiberglass casing or screens

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 19
installed in wells for use in potable water supplies shall be manufactured to be acceptable by
ANSI/NSF Standard 61 and upon state engineer approval.
11.2.4.4 Driving Non-metallic Casing. Non-metallic casing shall not be driven, jacked, or
dropped and may only be installed in an oversized borehole.
11.2.4.5 Protective Casing. If plastic or other non-metallic casing is utilized, the driller shall
install a protective steel casing which complies with the provisions of Subsection 11.2.3 or an
equivalent protective covering approved by the state engineer over and around the well casing
at ground surface to a depth of at least two and one half (2.5) feet. If a pitless adapter is
installed on the well, the bottom of the protective cover shall be placed above the pitless
adapter/well connection. If the pitless adapter is placed in the protective casing, the protective
casing shall extend below the pitless entrance in the well casing and be sealed both on the
outside of the protective casing and between the protective casing and well casing. The
protective cover shall be sealed in the borehole in accordance with the requirements of
Subsection 11.4. The annular space between the protective cover and non-metallic casing shall
also be sealed with acceptable materials in accordance with Subsection 11.4. A sanitary,
weather-tight seal or a completely welded cap shall be placed on top of the protective cover,
thus enclosing the well itself. If the sanitary seal is vented, screens shall be placed in the vent
to prevent debris insects, and other animals from entering the well. This protective casing
requirement does not apply to monitor wells. Figure 5 depicts this requirement.

R655-4-11.3 Casing Joints
11.3 Casing Joints.
11.3.1 General. All well casing joints shall be made water tight. In instances in which a
reduction in casing diameter is made, there shall be enough overlap of the casings to prevent
misalignment and to insure the making of an adequate seal in the annular space between
casings to prevent the movement of unstable sediment or formation material into the well, in
addition to preventing the degradation of the water supply by the migration of inferior quality
water through the annular space between the two casings.
11.3.2 Steel Casing. All steel casing shall be screw-coupled or welded. If the joints are welded,
the weld shall meet American Welding Society standards and be at least as thick as the wall
thickness of the casing and shall consist of at least two beads for the full circumference of the
joint and be fully penetrating. Spot welding of joints is prohibited.
11.3.3 Plastic Casing. All plastic well casing shall be mechanically screw coupled, chemically
welded, cam-locked or lug coupled to provide water tight joints as per ANSI/ASTM F480-95.
Metal screws driven into casing joints shall not be long enough to penetrate the inside surface
of the casing. Metal screws should be used only when surrounding air temperatures are below
50 degrees Fahrenheit (F) which retards the normal setting of the cement. Solvent-welded
joints shall not impart taste, odors, toxic substances, or bacterial contamination to the water in
the well.

R655-4-11.4 Surface Seals and Interval Seals
Well Surface Seals and Interval Seals
11.4 Surface Seals and Interval Seals – General
11.4.1 General. Before the drill rig is removed from the drill site of a well, a surface seal shall
be installed. Well casings shall be sealed to prevent the possible downward movement of
contaminated surface waters in the annular space around the well casing. The seal shall also
prevent the upward movement of artesian waters within the annular space around the well
casing. Depending upon hydrogeologic conditions around the well, interval seals may need to
be installed to prevent the movement of groundwater either upward or downward around the

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 20
well from zones that have been cased out of the well due to poor water quality or other
reasons. The following surface and interval seal requirements apply equally to rotary drilled,
cable tool drilled, bored, jetted, augered, and driven wells unless otherwise specified.
11.4.2 Seal Material.
11.4.2.1 General. The seal material shall consist of neat cement grout, sand cement grout,
unhydrated bentonite, or bentonite grout as defined in Section R655-4-2. Use of sealing
materials other than those listed above must be approved by the state engineer. Bentonite
drilling fluid (drilling mud), dry drilling bentonite, or drill cuttings are not an acceptable
sealing material. In no case shall drilling fluid (mud), drill cuttings, drill chips, or puddling clay
be used, or allowed to fill, partially fill, or fall into the required sealing interval of a well during
construction of the well. The annular space to be grouted must be protected from collapse and
the introduction of materials other than grout. All hydrated sealing materials (neat cement
grout, sand cement grout, bentonite grout) shall be placed by tremie pipe, pumping, or
pressure from the bottom of the seal interval upwards in one continuous operation when
placed below a depth of 30 feet or when placed below static groundwater level. Neat cement
and sand cement grouts must be allowed to cure a minimum of 24 hours before well drilling,
construction, or testing may be resumed. Allowable setting times may be reduced or
lengthened by use of accelerators or retardants specifically designed to modify setting time, at
the approval of the state engineer. The volume of annular space in the seal interval shall be
calculated by the driller to determine the estimated volume of seal material required to seal
the annular space. The driller shall place at least the volume of material equal to the volume of
annular space, thus ensuring that a continuous seal is placed. The driller shall maintain the
well casing centered in the borehole during seal placement using centralizers or other means
to ensure that the seal is placed radially and vertically continuous. Neat cement and sand
cement grout shall not be used for surface or interval seals with PVC and other approved non-
metallic casing unless specific state engineer approval is obtained.
11.4.2.2 Bentonite Grout. Bentonite used to prepare grout for sealing shall have the ability to
gel; not separate into water and solid materials after it gels; have a hydraulic conductivity or
permeability value of 10E-7 centimeters per second or less; contain at least 20 percent solids
by weight of bentonite, and have a fluid weight of 9.5 pounds per gallon or greater and be
specifically designed for the purpose of sealing. In addition, if a bentonite grout is to be placed
in the vadose zone (unsaturated interval), then clean rounded fine sand shall be added to the
bentonite grout in order to increase the overall solids content and stabilize the grout from
dehydrating and cracking in that interval. For 20% solids bentonite grout, at least 100 pounds
of clean rounded fine sand shall be added. For 30% solids bentonite grout, at least 50 pounds
of clean fine sand shall be added. Bentonite grout shall not be used for sealing intervals of
fractured rock or sealing intervals of highly unstable material that could collapse or displace
the sealing material, unless otherwise approved by the state engineer. Bentonite grout shall
not be used as a sealing material where rapidly flowing groundwater might erode it. Bentonite
or polymer drilling fluid (mud) does not meet the definition of a grout with respect to density,
gel strength, and solids content and shall not be used for sealing purposes. At no time shall
bentonite grout contain materials that are toxic, polluting, develop odor or color changes, or
serve as a micro-bacterial nutrient. All bentonite grout shall be prepared and installed
according to the manufacturer's instructions and these rules. All additives must be certified by
a recognized certification authority such as NSF and approved by the state engineer. All
bentonite used in any well shall be certified by NSF/ANSI approved standards for use in
potable water supply wells, or equivalent standards as approved by the state engineer.
11.4.2.3 Unhydrated Bentonite. Unhydrated bentonite (e.g., granular, tabular, pelletized, or
chip bentonite) may be used in the construction of well seals above a depth of 50 feet.

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 21
Unhydrated bentonite can be placed below a depth of 50 feet when placed inside the annulus
of two casings, when placed using a tremie pipe, or by using a placement method approved by
the state engineer. The bentonite material shall be specifically designed for well sealing and be
within industry tolerances. All unhydrated bentonite used for sealing must be free of organic
polymers and other contamination. Placement of bentonite shall conform to the
manufacturer's specifications and instructions and result in a seal free of voids or bridges.
Granular or powdered bentonite shall not be placed under water by gravity feeding from the
surface. When placing unhydrated bentonite, a sounding or tamping tool shall be run in the
sealing interval during pouring to measure fill-up rate, verify a continuous seal placement, and
to break up possible bridges or cake formation.
11.4.3 Seal and Unperforated Casing Placement.
11.4.3.1 General Seal Requirements. Figure 1 illustrates the construction of a surface seal for a
typical well. The surface seal must be placed in an annular space that has a minimum diameter
of four (4) inches larger than the nominal size of the permanent well casing (This amounts to a
2-inch annulus). The surface seal must extend from land surface to a minimum depth of 30
feet. The completed surface seal must fully surround the permanent well casing, must be
evenly distributed, free of voids, and extend to undisturbed or recompacted soil. In
unconsolidated formations such as gravels, sands, or other unstable conditions when the use of
drilling fluid or other means of keeping the borehole open are not employed, either a
temporary surface casing with a minimum depth of 30 feet and a minimum nominal diameter
of four (4) inches greater than the outermost permanent casing shall be utilized to ensure
proper seal placement or the well driller shall notify the state engineer's office that the seal will
be placed in a potentially unstable open borehole without a temporary surface casing by
telephone or FAX in conjunction with the start card submittal in order to provide an
opportunity for the state engineer's office to inspect the placement of the seal. If a temporary
surface casing is utilized, the surface casing shall be removed in conjunction with the
placement of the seal. Alternatively, conductor casing may be sealed permanently in place to a
depth of 30 feet with a minimum 2-inch annular seal between the surface casing and borehole
wall. If the temporary surface casing is to be removed, the surface casing shall be withdrawn
as sealing material is placed between the outer-most permanent well casing and borehole wall.
The sealing material shall be kept at a sufficient height above the bottom of the temporary
surface casing as it is withdrawn to prevent caving of the borehole wall. If the temporary
conductor casing is driven in place without a 2-inch annular seal between the surface casing
and borehole wall, the surface casing shall be removed. Specific state engineer approval must
be obtained on a case-by-case basis for any variation of these requirements. Surface seals and
unperforated casing shall be installed in wells located in unconsolidated formation such as
sand and gravel with minor clay or confining units; unconsolidated formation consisting of
stratified layers of materials such as sand, gravel, and clay or other confining units; and
consolidated formations according to the following procedures.
11.4.3.2 Unconsolidated Formation without Significant Confining Units. This includes wells
that penetrate an aquifer overlain by unconsolidated formations such as sand and gravel
without significant clay beds (at least six feet thick) or other confining formations. The surface
seal must be placed in a 2-inch annular space to a minimum depth of 30 feet. Permanent
unperforated casing shall extend at least to a depth of 30 feet and also extend below the lowest
anticipated pumping level. Additional casing placed in the open borehole below the required
depths noted above shall meet the casing requirements of Subsection 9.2 unless the casing is
installed as a liner inside a larger diameter approved casing.
11.4.3.3 Unconsolidated Formation with Significant Confining Units. This includes wells that
penetrate an aquifer overlain by clay or other confining formations that are at least six (6) feet

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 22
thick. The surface seal must be placed in a 2-inch annular space to a minimum depth of 30 feet
and at least five (5) feet into the confining unit above the water bearing formation.
Unperforated casing shall extend from ground surface to at least 30 feet and to the bottom of
the confining unit overlying the water bearing formation. If necessary to complete the well, a
smaller diameter casing, liner, or well screen may be installed below the unperforated casing.
The annular space between the two casings shall be sealed with grout, bentonite, or a
mechanical packer. Additional casing placed in the open borehole below the required depths
noted above shall meet the casing requirements of Subsection 11.2 unless the casing is
installed as a liner inside a larger diameter approved casing.
11.4.3.4 Consolidated Formation. This includes drilled wells that penetrate an aquifer, either
within or overlain by a consolidated formation. The surface seal must be placed in a 2-inch
annular space to a minimum depth of 30 feet and at least five (5) feet into competent
consolidated formation. Unperforated permanent casing shall be installed to extend to a depth
of at least 30 feet and the lower part of the casing shall be driven and sealed at least five (5)
feet into the consolidated formation. If necessary to complete the well, a smaller diameter
casing, liner, or well screen may be installed below the unperforated casing. The annular space
between the two casings shall be sealed with grout, bentonite, or a mechanical packer.
Additional casing placed in the open borehole below the required depths noted above shall
meet the casing requirements of Subsection 11.2 unless the casing is installed as a liner inside a
larger diameter approved casing.
11.4.3.5 Sealing Artesian Wells. Unperforated well casing shall extend into the confining
stratum overlying the artesian zone, and shall be adequately sealed into the confining stratum
to prevent both surface and subsurface leakage from the artesian zone. If leaks occur around
the well casing or adjacent to the well, the well shall be completed with the seals, packers, or
casing necessary to eliminate the leakage. The driller shall not move the drilling rig from the
well site until leakage is completely stopped, unless authority for temporary removal of the
drilling rig is granted by the state engineer, or when loss of life or property is imminent. If the
well flows naturally at land surface due to artesian pressure, the well shall be equipped with a
control valve so that the flow can be completely stopped. The control valve must be available
for inspection by the state engineer at all times. All flowing artesian water supply wells shall
be tested for artesian shut-in pressure in pounds per square inch and rate of flow in cubic feet
per second, or gallons per minute, under free discharge conditions. This data shall be reported
on the well log.
11.4.3.6 Exceptions: With state engineer approval, exceptions to minimum seal depths can be
made for shallow wells where the water to be produced is at a depth less than 30 feet. In no
case shall a surface seal extend to a total depth less than 10 feet below land surface.
11.4.4 Interval Seals. Formations containing undesirable materials (e.g., fine sand and silt that
can damage pumping equipment and result in turbid water), contaminated groundwater, or
poor quality groundwater must be sealed off so that the unfavorable formation cannot
contribute to the performance and quality of the well. These zones, as well as zones with
significantly differing pressures, must also be sealed to eliminate the potential of cross
contamination or commingling between two aquifers of differing quality and pressure. Figure
4 illustrates this situation. Unless approved by the state engineer, construction of wells that
cause the commingling or cross connection of otherwise separate aquifers is not allowed.
11.4.5 Other Sealing Methods. In wells where the above-described methods of well sealing do
not apply, special sealing procedures can be approved by the state engineer upon written
request by the licensed well driller.

R655-4-11.5 Special Requirements for Oversized and Gravel Packed Wells

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 23
Gravel Pack or Filter Material
11.5 This section applies to wells in which casing is installed in an open borehole without
driving or drilling in the casing and an annular space is left between the borehole wall and
well casing (e.g., mud rotary wells, flooded reverse circulation wells, air rotary wells in open
bedrock).
11.5.1 Oversized Borehole. The diameter of the borehole shall be at least four (4) inches larger
than the outside diameter of the well casing to be installed to allow for proper placement of the
gravel pack and/or formation stabilizer and adequate clearance for grouting and surface seal
installations. In order to accept a smaller diameter casing in any oversized borehole
penetrating unconsolidated or stratified formations, the annular space must be sealed in
accordance with Subsection 11.4. In order to minimize the risk of: 1) borehole caving or
collapse; 2) casing failure or collapse; or 3) axial distortion of the casing, it is required that the
entire annular space in an oversized borehole between the casing and borehole wall be filled
with formation stabilizer such as approved seal material, gravel pack, filter material or other
state engineer-approved materials. Well casing placed in an oversized borehole should be
suspended at the ground surface until all formation stabilizer material is placed in order to
reduce axial distortion of the casing if it is allowed to rest on the bottom of an open oversized
borehole. In order to accept a smaller diameter casing, the annular space in an oversized
borehole penetrating unconsolidated formations (with no confining layer) must be sealed in
accordance with Subsection 11.4 to a depth of at least 30 feet or from static water level to
ground surface, whichever is deeper. The annular space in an oversized borehole penetrating
stratified or consolidated formations must be sealed in accordance with Subsection 11.4 to a
depth of at least 30 feet or five (5) feet into an impervious strata (e.g., clay) or competent
consolidated formation overlying the water producing zones back to ground surface,
whichever is deeper. Especially in the case of an oversized borehole, the requirements of
Subsection 11.4.4 regarding interval sealing must be followed.
11.5.2 Gravel Pack or Filter Material. The gravel pack or filter material shall consist of clean,
well-rounded, chemically stable grains that are smooth and uniform. The filter material should
not contain more than 2% by weight of thin, flat, or elongated pieces and should not contain
organic impurities or contaminants of any kind. In order to assure that no contamination is
introduced into the well via the gravel pack, the gravel pack must be washed with a minimum
100 ppm solution of chlorinated water or dry hypochlorite mixed with the gravel pack at the
surface before it is introduced into the well (see Table 7 of these rules for required amount of
chlorine material).
11.5.3 Placement of Filter Material. All filter material shall be placed using a method that
through common usage has been shown to minimize a) bridging of the material between the
borehole and the casing, and b) excessive segregation of the material after it has been
introduced into the annulus and before it settles into place. It is not acceptable to place filter
material by pouring from the ground surface unless proper sounding devices are utilized to
measure dynamic filter depth, evaluate pour rate, and minimize bridging and formation of
voids.
11.5.4 No Surface Casing Used. If no permanent conductor casing is installed, neat cement
grout, sand cement grout, bentonite grout, or unhydrated bentonite seal shall be installed in
accordance with Subsection 11.4. Figure 2 of these rules illustrates the construction of a
typical well of this type.
11.5.5 Permanent Conductor Casing Used. If permanent conductor casing is installed, it shall
be unperforated and installed and sealed in accordance with Subsection 11.4 as depicted in
Figure 3 of these rules. After the gravel pack has been installed between the conductor casing
and the well casing, the annular space between the two casings shall be sealed by either

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 24
welding a water-tight steel cap between the two casings at land surface or filling the annular
space between the two casings with neat cement grout, sand cement grout, bentonite grout, or
unhydrated bentonite from at least 50 feet to the surface and in accordance with Subsection
11.4. If a hole will be created in the permanent conductor casing in order to install a pitless
adapter into the well casing, the annual space between the conductor casing and well casing
shall be sealed to at least a depth of thirty (30) feet with neat cement grout, sand cement grout,
bentonite grout, or unhydrated bentonite. A waterproof cap or weld ring sealing the two
casings at the surface by itself without the annular seal between the two casings is
unacceptable when a pitless adapter is installed in this fashion. Moreover in this case, the
annular space between the surface casing and well casing must be at least 2 inches in order to
facilitate seal placement.
11.5.6 Gravel Feed Pipe. If a gravel feed pipe, used to add gravel to the gravel pack after well
completion, is installed, the diameter of the borehole in the sealing interval must be at least
four (4) inches in diameter greater than the permanent casing plus the diameter of the gravel
feed pipe. The gravel feed pipe must have at least 2-inches of seal between it and the borehole
wall. The gravel feed pipe must extend at least 18 inches above ground and must be sealed at
the top with a watertight cap or plug (see Figure 2).
11.5.7 Other Gravel Feed Options. If a permanent surface casing or conductor casing is
installed in the construction of a filter pack well, a watertight, completely welded, steel plate
(weld ring) at least 3/16 of an inch in thickness shall be installed between the inner production
casing and the outer surface/conductor casing at the wellhead. A watertight fill port with
threaded cap may be installed for the purpose of placing additional filter pack material in the
well.

R655-4-11.6 Protection of the Aquifer
11.6 Protection of the Aquifer
11.6.1 Drilling Fluids and LCMs. The well driller shall take due care to protect the producing
aquifer from clogging or contamination. Organic substances or phosphate-based substances
shall not be introduced into the well or borehole during drilling or construction. Every effort
shall be made to remove all substances and materials introduced into the aquifer or aquifers
during well construction. "Substances and materials" shall mean all bentonite- and polymer-
based drilling fluids, filter cake, and any other inorganic substances added to the drilling fluid
that may seal or clog the aquifer. All polymers and additives used in any well shall be certified
by NSF/ANSI approval standards for use in potable water supply wells, or equivalent
standards as approved by the state engineer. The introduction of lost circulation materials
(LCM's) during the drilling process shall be limited to those products which will not present a
potential medium for bacterial growth or contamination. Only LCM's which are non-organic,
which can be safely broken down and removed from the borehole, may be utilized. This
includes, but is not limited to, paper/wood products, brans, hulls, grains, starches,
hays/straws, and proteins. This is especially important in the construction of wells designed to
be used as a public water system supply. All polymers and additives used in any well shall be
certified by NSF/ANSI approval standards for use in potable water supply wells, or equivalent
standards as approved by the Division. The product shall be clearly labeled as meeting these
standards. Polymers and additives must be designed and manufactured to meet industry
standards to be nondegrading and must not act as a medium which will promote growth of
microorganisms.
11.6.2 Containment of Drilling Fluid. Drilling or circulating fluid introduced into the drilling
process shall be contained in a manner to prevent surface or subsurface contamination and to
prevent degradation of natural or man-made water courses or impoundments. Rules

BC&A
STOCKTON TOWN STANDARD REQUIREMENTS AND REGULATORY CITATIONS
OLD TANK WELL PROJECT ATTACHMENT C PAGE - 25
regarding the discharges to waters of the state are promulgated under R317-8-2 of the Utah
Administrative Code and regulated by the Utah Division of Water Quality (Tel. [phone]).
Pollution of waters of the state is a violation of the Utah Water Quality Act, Utah Code
Annotated Title 19, Chapter 5.
11.6.3 Mineralized, Contaminated or Polluted Water. Whenever a water bearing stratum that
contains nonpotable mineralized, contaminated or polluted water is encountered, the stratum
shall be adequately sealed off so that contamination or co-mingling of the overlying or
underlying groundwater zones will not occur (see Figure 4) Water bearing zones with
differing pressures must also be isolated and sealed off in the well to avoid aquifer depletion,
wasting of water, and reduction of aquifer pressures.
11.6.4 Down-hole Equipment. All tools, drilling equipment, and materials used to drill, repair,
renovate, clean, or install a pump in a well shall be free of contaminants prior to beginning well
construction or other in-well activity. Contaminants include lubricants, fuel, bacteria, etc. that
will reduce the well efficiency, and any other item(s) that will be harmful to public health
and/or the resource or reduce the life of the water well. It is recommended that excess
lubricants placed on drilling equipment be wiped clean prior to insertion into the borehole.
11.6.5 Well Disinfection and Chlorination of Water. No contaminated or untreated water shall
be placed in a well during construction. Water should be obtained from a chlorinated
municipal system. Where this is not possible, the water must be treated to give at least 100
parts per million free chlorine residual. Upon completion of a well or work on a well, the
driller or pump installer shall disinfect the well using accepted disinfection procedures to give

ground surface and if a pitless adapter/unit is installed, the standards of Subsection R655-4-
11(11.5.5) shall be employed to ensure proper sealing between casings is maintained.
16.9 Water Level and Flow Measurement. Following pump installation and repair work, the
well shall be left in such a manner to allow for access to water level measurements in accordance
with R655-4-11(11.7.2). After pump installation and repair work is completed on a well, the
static water level should be measured after which a test should be performed to determine the
rate at which groundwater can be reliably produced from the well. Pumping water level should
be measured and recorded during this test. Static water level and well testing information shall
be noted on the official submittal of the Pump Log by the pump installer or well driller.
16.10 Surface Security. If it becomes necessary for the pump installer to temporarily
discontinue operation on a well before completion or otherwise leave the well unattended, the
well must be covered securely to prevent contaminants from entering the casing and rendered
secure against entry by children, vandals, domestic animals, and wildlife.
16.11 Above-grade connections. An above-grade connection into the top or side of a well casing
shall be at least eighteen inches (18") above the land surface and shall be constructed so as to
exclude dirt or other foreign matter by at least one of the following methods, as may be
applicable:
(A) Threaded connection;
(B) Welded connection;
(C) Expansion sealer;
(D) Bolted flanges with rubber gaskets;
(E) Overlapping well cap; or
(F) If a water well pump is mounted or sealed on a concrete pedestal, the casing shall
extend at least to the top of the pedestal and at least eighteen inches (18") above the land
surface.
16.12 Pitless Connections. Pitless adapters and units shall be installed in accordance with the
standards set forth in Subsection R655-4-11(11.7.5). Pitless adapters shall be installed below
the frost line. A below-ground connection shall not be submerged in water at the time of
installation. Holes cut in the casing through which the pitless adapters are installed must be
sized and constructed so as to guarantee a watertight seal with the pitless adapter in place.
16.13 Backflow Protection. When a check valve or foot valve is not a part of the pump, a check
valve or back-siphon prevention device shall be installed on the pump discharge line within the
well or beyond the well to eliminate the opportunity for contaminated water to backflush into
the well. Such device must be designed to direct or isolate the water flow to prevent water in
the distribution line from running back down the well during removal or repair to the pump and
pumping equipment. When a flow meter is installed on a well the meter must be located
downstream from the backflow preventer and be placed in accordance with manufacturer
spacing specifications.
16.14 Hand Pumps. Hand pumps shall be of the force type equipped with a packing gland around
the pump rod, a delivery spout which is closed and downward directed, and a one-piece bell-
type base which is part of the pump stand or is attached to the pump column in a watertight
manner. The bell base of the pump shall be bolted with a gasket to a flange which is securely
attached to the casing or pipe sleeve.
16.15 Pumping Water Level. In a screened or perforated well, the well pump setting and suction
inlet shall be located so that the pumping level of the water cannot be drawn below the top of
the screen.
16.16 Pump and Column/Drop Pipe Removal. During any repair or installation of a water well
pump, the licensed installer shall make a reasonable effort to maintain the integrity of ground

APPENDIX D
WELL DRILLING FACT SHEET REGARDING DISCHARGE
Fact Sheet Regarding Water Discharges From Water Well Drilling and Operation Prepared by: Utah Division of Water Quality Updated July 2002 Background: Utah Administrative Code (UAC) R317-8-2 requires a UPDES discharge permit for the discharge of pollutants from any point source into waters of the State. A point source is defined as “any discernible, confined, and discrete conveyance, including but not limited to any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, from which pollutants are or may be discharged.” Through the use of various drilling methods and reasonable best management practices, water well drilling generally can be conducted such that no discharge occurs or that only de minimis (insignificant) amounts of pollutants would be released into waters of the State. As such, it has been the policy of the Division of Water Quality to not require water well drilling operations to obtain a discharge permit as long as they do not discharge or discharge de minimis amounts of pollutants. There may be circumstances where a discharge permit is necessary or desired by the well driller or owner. However, because a discharge permit can take several months to issue, requires payment of a permit fee, and because the permit would contain specific enforceable effluent quality limits and frequent self-monitoring and reporting requirements, it is highly recommended that all options to avoid discharge or attain the de minimis discharge be explored before pursuing an individual discharge permit. Best Management Practices (BMP’s) The goal of BMP implementation is to avoid discharge or, if this is not practicable, to obtain a de minimis pollutant discharge during any phase of well development. The primary pollutants of concern are total suspended solids and turbidity in the form of drill cuttings and muds. Occasionally chemicals such as surfactants are used during the drilling operation. It is the responsibility of the operator and/or owner to assure that BMP’s are properly installed and operated in order to contain all fluids or to produce a de minimis pollutant discharge to waters of the State. Some BMP’s are indicated below: 1. Drill pits or ponds of adequate size for total containment of all fluids containing drill cuttings, surfactants and associated chemicals. 2. Pits or ponds used for settling; followed by filter cloth and/or straw bales which can be used for filtration prior to fluids entering surface waters of the state. 3. Land application of produced waters during drilling, pump testing, and well development where no discharge would occur to waters of the State. 4. Land application where sufficient filtration through vegetation removes solids and turbidity before water is diffused and enters any surface waters. 5. Other sediment and turbidity reduction treatment such as frac tanks, cyclone separators, etc. Pollution of waters of the state is a violation of the Water Quality Act, UCA 19-5, which provides for significant monetary penalties, and additional penalties for violations that are willful or caused by gross negligence.
