Utah Admin. Code R309-600-13 - New Ground-water Sources of Drinking Water
(1) Prior to constructing a new ground-water
source of drinking water, each PWS shall develop a PER which demonstrates
whether the source meets the requirements of this section and submit it to DDW.
Additionally, engineering information in accordance with
R309-515-6(5)(a)
or
R309-515-7(4)
must be submitted to DDW. The Director will not grant plan approval until both
source protection and engineering requirements are met. Construction standards
relating to protection zones and management areas (fencing, diversion channels,
sewer line construction, and grouting, etc.) are found in R309-515. After the
source is constructed a DWSP Plan must be developed, submitted, and implemented
accordingly.
(2) Preliminary
Evaluation Report for New Sources of Drinking Water - PERs shall cover all four
zones or the entire management area. PERs should be developed in accordance
with the "Standard Report Format for New Wells and Springs." This document may
be obtained from DDW. PWSs shall include the following four sections in each
PER:
(a) Delineation Report for Estimated
DWSP Zones - The same requirements apply as in
R309-600-9(6),
except that the hydrogeologic data for the PER must be developed using the best
available data which may be obtained from: surrounding wells, published
information, or surface geologic mapping. PWSs must use the Preferred
Delineation Procedure to delineate protection zones for new wells. The
Delineation Report for Estimated DWSP Zones shall be stamped and signed by a
professional geologist or professional engineer unless the Optional Two-Mile
Radius Delineation Procedure is used for a new spring.
(b) Inventory of Potential Contamination
Sources and Identification and Assessment of Controls - The same requirements
apply as in
R309-600-10(1)
and (2). Additionally, the PER must
demonstrate that the source meets the following requirements:
(i) Protection Areas Delineated using the
Preferred Delineation Procedure in Protected Aquifers - A PWS shall not locate
a new ground-water source of drinking water where an uncontrolled potential
contamination source or a pollution source exists within zone one.
(ii) Protection Areas Delineated using the
Preferred Delineation Procedure in Unprotected Aquifers - A PWS shall not
locate a new ground-water source of drinking water where an uncontrolled
potential contamination source or an uncontrolled pollution source exists
within zone one. Additionally, a new ground-water source of drinking water may
not be located where a pollution source exists within zone two unless the
pollution source implements design standards which prevent contaminated
discharges to ground water.
(iii)
Management Areas Delineated using the Optional Two-Mile Radius Delineation
Procedure - A PWS shall not locate a new spring where an uncontrolled potential
contamination source or a pollution source exists within zone one.
Additionally, a new spring may not be located where a pollution source exist
within the management area unless: a hydrogeologic report in accordance with
R309-600-9(6)(b)(ii)
which verifies that it does not impact the spring; or the pollution source
implements design standards which prevent contaminated discharges to ground
water.
(c) Land
Ownership Map - A land ownership map which includes all land within zones one
and two or the entire management area. Additionally, include a list which
exclusively identifies the land owners in zones one and two or the management
area, the parcel(s) of land which they own, and the zone in which they own
land. A land ownership map and list are not required if ordinances are used to
protect these areas.
(d) Land Use
Agreements, Letters of Intent, or Zoning Ordinances - Land use agreements which
meet the requirements of the definition in
R309-600-6(1)(p).
Zoning ordinances which are already in effect or letters of intent may be
substituted for land use agreements; however, they must accomplish the same
level of protection that is required in a land use agreement. Letters of intent
must be notarized, include the same language that is required in land use
agreements, and contain the statement that "the owner agrees to record the land
use agreement in the county recorder's office, if the source proves to be an
acceptable drinking water source." The PWS shall not introduce a new source
into its system until copies of all applicable recorded land use agreements are
submitted to DDW.
(3)
Sewers Within DWSP Zones and Management Areas - Sewer lines may not be located
within zones one and two or a management area unless the criteria identified
below are met. If sewer lines are located or planned to be located within zones
one and two or a management area, the PER must demonstrate that they comply
with these criteria. Sewer lines that comply with these criteria may be
assessed as adequately controlled potential contamination sources.
(a) Unprotected Aquifers -
(i) Zone one- all sewer lines and laterals
shall be at least 50 feet from the wellhead or margin of the collection area,
and be constructed in accordance to
R309-515-6.
(ii) Zone two- all sewer lines and laterals
within zone two or a management area shall be constructed in accordance with
R309-515-6.
(b) Protected Aquifers - in zone
one all sewer lines and laterals shall be constructed in accordance with
R309-515-6,
and shall be at least 10 feet from the wellhead or margin of the collection
area.
(4) Use waivers
for the VOC and pesticide parameter groups may be issued if the inventory of
potential contamination sources indicates that the chemicals within these
parameter groups are not used, disposed, stored, transported, or manufactured
within zones one, two, and three or the management area.
(5) Replacement Wells - A PER is not required
for proposed wells, if the PWS receives written notification from the Director
that the well is classified as a replacement well. The PWS must submit a letter
requesting that the well be classified as a replacement well and include
documentation to show that the conditions required in
R309-600-6(1)(y)
are met. If a proposed well is classified as a replacement well, the PWS is
still required to submit and obtain written approval for all other information
as required in:
(a) DWSP Plan for New Sources
of Drinking Water (refer to R309-600-13(6), and
(b) the Outline of Well Approval Process
(refer to
R309-515-6(5)
).
(6) DWSP Plan for New
Sources of Drinking Water - The PWS shall submit a DWSP Plan in accordance with
R309-600-7(1)
for any new ground-water source of drinking water within one year after the
date of the Director's concurrence letter for the PER. In developing this DWSP
Plan, PWSs shall refine the information in the PER by applying any new, as-
constructed characteristics of the source (i.e., pumping rate, aquifer test,
etc.).
