PROPOSAL:
The Division of Drinking Water made the substantivechangesto R309-515-6(4) to delete specialconstruction requirements for sewer mains, laterals, and maintenance holes located in -Source
ProtectionZone2.
The Divisionmade nonsubstantive changesthroughout the R309-515 to comply with RulewritingManualforUtah and deleted references to parts of R309-540 in R309-515-5(5)(f),R309-515-6(13),andR309-515-6(13)(e)whichwillnolonger

The public comment period ended on May 1, 2024, and the Division did not receive any comments on the proposed rule revision.
HISTORY/CONTEXT:
TheproposedamendmenttoR309-515-6(4)deletesspecialconstructionrequirementsforsewermains, laterals, and maintenance holes located in Source Protection Zone 2 but retains them forSource
Protection Zone 1. The current requirements can rarely be met, and the divisionfrequently must issue exceptions to the rule requirements, which the division believes areunnecessarytoprovideprotectionofgroundwatersourcesinZone2.
The proposedamendmentto R309-515-6(4) also clarifiesthat the special constructionrequirementsapplytosewermainsandlateralscarryingwastewaterfromabuildingtoapublicsewer, septic system,
or wastewater dispersal system and clarifies that the special constructionrequirementsdon'tapplytofloordrains.
The proposed amendment deletes Subsection R309-515-6(4)(h), which currently requires, as aspecialconstructionrequirement,animpermeablecutoffwallalongtheupgradientedgeofsewertrenches
in Source Protection Zone 1for protected aquifers and in Source Protection Zone 2 forunprotected aquifers. The requirement would no longer apply to sewer lines and laterals in Zone2
because all special construction requirements are being deleted. The division also believes thisrequirement is overly restrictive and unnecessary for the protection of groundwater sources
inZone1.
TheproposedrulehasbeendistributedwithintheDivisionandtopublicwatersystems,consultants, and others for review. The Division has considered all comments received andrevised the rule as
necessary. The proposed rule has also been pre-filed with the Office ofAdministrativeRulesforreviewasrequiredbyExecutiveOrder2021-12,EstablishingEffectiveOversightOverStateAgencyRulemaking,issuedbyGovernorCoxonMay6,2021.
DIVISIONSTAFF/DIRECTORRECOMMENDATION:
The Division recommends that the Drinking Water Board adopt the amendment toR309-515-5and-6 and instruct Division staff to file the appropriate action withthe Officeof Administrative

until permanent equipment can be installed.(b) [At all times]Continually, during the progress of work, the contractor shall provide protection to prevent tampering with the well or
entrance of foreign materials.(9) Well Abandonment.(a) Test wells and groundwater sources, which will be permanently abandoned shall be abandoned in accordance with Section 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]cementgrout or
concrete, these materials shall be applied to the well- hole through a pipe, tremie, or bailer.(10) Well Assessment.(a) Step Drawdown Test.Preliminary to the constant-rate test required
[below]in Subsection R309-515-6(10)(b), it is recommended that a [step-drawdown]stepdrawdown test[ (], which is 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]before 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 anticipated drawdown, it will be capable of pumping [in excess of]more

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[ (], which is the 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[),];(B) 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.(11) Well

(refer to R309-540-5(2) (a) through (h)).].(f) Fencing.Where necessary to protect the quality of the well water, the Director may require that certain wells be fenced in a manner similar
to fencing required around spring areas.(g) Access.An access shall be provided either through the well house roof or sidewalls in the event the pump must be pulled for replacement or
servicing the well.
R309-515-7. [Ground Water]Groundwater- Springs.(1) General.Springs vary greatly in their characteristics and they should be observed for some time [prior to]before development to determine
any flow and quality variations.[] Springs determined to be under the direct influence of surface water shall comply with surface water treatment requirements.(2) Source Protection.Public
drinking water systems are responsible for protecting their spring sources from contamination. []The selection of a spring shall only be made after consideration of the requirements
of Section R309-515-4.[] Springs must be located in an area that shall minimize threats from existing or potential sources of pollution. []A Preliminary Evaluation Report on source protection
issues is required by Subsection R309-600-13(2).[] If certain precautions are taken, sewer lines may be permitted within a public drinking water system's source protection zones at the
discretion of the Director. []When sewer lines are permitted in protection zones both sewer lines and [manholes]maintenance holes shall be specially constructed as described in SubsectionR309-515-6(4).(3)
Surface Water Influence.Some springs yield water that has been filtered underground for years; other springs yield water that has been filtered underground only a matter of hours. []Even
with proper development, the untreated water from certain springs may exhibit turbidity and high coliform counts. []This indicates that the spring water is not being sufficiently filtered
in underground travel.[] If a spring is determined to be under the direct influence of surface water, it shall be treated to meet the surface water treatment requirements specified in
Section R309-505-6.(4) Pre-construction SubmittalBefore beginning spring development construction, the following information shall be submitted to the Director and approved in writing:(a)
detailed plans and specifications covering the development work;(b) if available, a copy of an engineer's or geologist's statement indicating:(i) the historical record of spring flow
variation;(ii) expected minimum flow and the time of year it will occur;(iii) expected maximum flow and the time of year it will occur;(iv) expected average flow; and[,](v) the behavior

of the spring during drought conditions;(c) acceptable evidence that the water system has a legal right to divert water for the proposed use[(s)] from the spring source[(s);];(d) a
Preliminary Evaluation Report on source protection issues as required by Section R309-600-13;(e) a copy of the chemical analyses required by Subsection R309-515-4(5[) ;]); and[,](f)
an assessment of whether the spring is under the direct influence of surface water[(], refer to Subsection R309-505-7(1)(a[)).]).(5) Information Required after Spring Development.After
development of a spring as a drinking water source, the following information shall be submitted to the Director for review.(a) proof of satisfactory bacteriologic quality;(b) information
on the rate of flow developed from the spring.Immediately after spring development, the water system shall collect monthly spring flow data during operating seasons when the spring is
reasonably accessible, as a minimum, for three years, and submit spring flow data to the Director for determination of spring yield. []After evaluating the spring flow information including
seasonal and annual variations, the Director will determine a spring yield, which will be used in assessing the number of and type of connections that can be served by the spring. []The
spring yield typically is set at the 25th percentile of the spring flow data.[] If the spring exhibits significant seasonal or annual variations, the spring yield may be assessed on
a case-by-case basis.(c) Record drawings of spring development.(6) Operating Permit Required.Water from the spring can be introduced into a public water system only after it has been
approved for use, in writing, as evidenced by the issuance of an Operating Permit by the Director[ (], see Section R309-500-9[).].(7) Spring Development.The development of springs for
drinking water purposes shall comply with the following requirements.(a) The spring collection device, whether it be collection tile, perforated pipe, imported gravel, infiltration
boxes, or tunnels must be covered with a minimum of 10 feet of relatively impervious soil cover. []Such cover must extend a minimum of 15 feet in all horizontal directions from the spring
collection device. []Clean, inert, non-organic material shall be placed in the vicinity of the collection device[(s).].(b) Where it is impossible to achieve the 10 feet of relatively
impervious soil cover, an acceptable alternate will be the use of an impermeable liner provided that:(i) the liner has a minimum thickness of at least 40 mils;(ii) [all seams]each
seam in the liner [are]is folded or welded to prevent leakage;(iii) the liner is certified as complying with ANSI/NSF Standard 61. []This requirement is waived if certain that the drinking
water will not contact the liner;(iv) the liner is installed in such a manner as to assure its integrity. []No stones, two inches or larger, or sharp edged, shall be located within
two inches of the liner;(v) a minimum of two feet of relatively impervious soil cover is placed over the impermeable liner; and[,](vi) the soil and liner cover are extended a minimum
of 15 feet in [all]every horizontal direction[s] from the collection devices.(c) Each spring collection area shall be provided with at least one collection box to permit spring inspection
and testing.(d) [All]Each junction box[es] and collection box[es,] must comply with Rule R309-545 with respect to access openings, venting, and tank overflow.[] Lids for these spring
boxes shall be gasketed and the box adequately vented.(e) The spring collection area shall be surrounded by a fence located a distance of 50 feet[ (], preferably 100 feet if conditions
allow[)], from [all]each collection device[s] on land at an elevation equal to or higher than the collection device, and a distance of 15 feet from [all]each collection device[s] on
land at an elevation lower than the collection device. []The elevation datum to be used is the surface elevation at the point of collection. []The fence shall be at least ["]stock tight["
(], see Rule R309-110[). ]. In remote areas where no grazing or public access is possible, an exception to the fencing requirement may be granted by the Director. []In populated areas,
a six-foot high chain link fence with three strands of barbed wire may be required.(f)Within the fenced area any[ll] vegetation having deep roots shall be removed by a means not negatively
affecting water quality.(g) A diversion channel, or berm, capable of diverting [all]the entirety of anticipated surface water runoff away from the spring collection area shall be constructed
immediately inside the fenced area.(h) A permanent flow-measuring device shall be installed. []Flow measurement devices such as critical depth meters or weirs shall be properly housed
and otherwise protected.(i) The spring shall be developed as thoroughly as possible to minimize the possibility of excess spring water ponding within the collection area. []Where the
ponding of spring water is unavoidable, the excess shall be collected by shallow piping or french drain, and be routed beyond and down grade of the fenced area[ required above], whether
or not a fence is in place.
R309-515-8. Operation and Maintenance.(1) Spring Collection Area Maintenance.(a) Spring collection areas shall be periodically[ (], preferably annually[)], cleared of deep-rooted
vegetation to prevent root growth from clogging collection lines.[] Frequent hand or mechanical clearing of spring collection areas and diversion channel is strongly recommended. []It
is advantageous to encourage the growth of grasses and other shallow rooted vegetation for erosion control and to inhibit the growth of more detrimental flora.(b) No pesticide [(e.g.,]or
herbicide[)] may be applied on a spring collection area without the prior written approval of the Director.[] Such approval can be granted only when:(i) acceptable pesticides are proposed(ii)
the pesticide product manufacturer certifies that no harmful substance will be imparted to the water and[,](iii) spring development construction meets the requirements of [these r]Rules
R309-500 through R309-550.(2) Pump Lubricants.The [U.S.]US Food and Drug Administration (FDA) has approved propylene glycol and certain types of mineral oil for occasional contact with
or for addition to food products. []These oils are commonly referred to as ["]food-grade mineral oils[". All oil]. Oil lubricated pumps shall utilize food[]-grade mineral oil suitable
for human consumption as determined by the Director.(3) Algicide Treatment.No algicide shall be applied to a drinking water source unless specific approval is obtained from the Director.
Such approval will be given only if the algicide is certified as meeting the requirements of ANSI/NSF Standard 60, Water Treatment Chemicals - Health Effects.

Section 10-8-15 includes [ground-water]groundwater sources.(4) Zoning ordinances are an effective means to control potential contamination sources that may want to move into protection
areas. []They allow PWSs to prohibit facilities that would discharge contaminants directly to [ground water. ]groundwater. They also allow PWSs to review plans from potential contamination
sources to ensure there will be adequate spill protection and waste disposal procedures[, etc]. If zoning ordinances are not used, PWSs must establish a plan to contact potential contamination
sources individually as they move into protection areas, identify and assess their controls, and plan land management strategies if they are not adequately controlled.
