California Code of Regulations › Title 23 - Waters › Division 2 - Department of Water Resources › Chapter 6 - Encroachments › Article 6 - Requirements for Specific Types of Encroachments › Section 612.6 - Utility Encroachments

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) The
				  general standards in this section are the minimum requirements for Utility
				  Encroachments. These standards shall be met in addition to any requirements for
				  an encroachment permit as set forth in Sections
				  612.61 through
				  612.67, inclusively, of these
				  regulations. Each application shall be evaluated on an individual basis to
				  ensure the safety and integrity of the State Water Project's facilities and
				  right-of-way, and the safety of the public.
(1) All utilities conveying any substance
				  other than potable water shall be perpendicular to centerline of the State
				  Water Project's pipeline to minimize the potential impact of contamination to
				  State Water Project right-of-way. Exceptions will only be considered if the
				  crossing will not increase the potential for contamination to State Water
				  Project right-of-way.
(2) The
				  points where the proposed utilities enter and exit the Department's
				  right-of-way shall be plainly and permanently marked by sign posts extending
				  five (5) feet above grade. Applicant shall provide sign posts directly above
				  its utility centerline at all angle points within the Department's
				  right-of-way. The distance between adjacent sign posts shall not exceed a
				  maximum of five hundred (500) feet. Sign posts shall contain the name of
				  owner/operator, contents of the pipeline, utility identification, and an
				  emergency contact telephone number. Sign posts for angle points that lie in
				  roads shall be offset and have a reference noted. The location of the sign
				  posts shall be shown on the design plans.
(3) The location of the State Water Project's
				  pipeline, conveyance or aqueduct, and communication and control cables shall be
				  shown on the plans throughout the area of the proposed construction. Prior to
				  the Department issuing an encroachment permit, the pipeline, if present, and
				  the cable(s) shall be located and exposed by potholing. All work within three
				  (3) feet of the pipeline and the cable(s) shall be done using hand-held tools
				  only. The applicant shall contact:
a) The
				  appropriate Underground Service Alert regional notification center.
b) The Department's telecommunication
				  provider.
c) The Department for the
				  location(s) of the pipeline and the communication and control
				  cables.
(4) The presence
				  of a Department inspector will be required throughout the potholing exposure
				  process at the cost of the applicant. Applicant shall call the Field Division
				  Office having jurisdiction over the location of the proposed encroachment for
				  an appointment to perform the exposure of the pipeline and the cable(s).
(A) The resultant elevation information,
				  including datum, shall be delineated on the profile view and labeled as
SWP T.O.P. POTHOLED ELEVATION XX.X
Surface Elevation XX.X
CABLE POTHOLED ELEVATION XX.X
Surface Elevation XX.X
[Where xx.x is the elevation in feet to the nearest
					 tenth.]
(B) The following
				  not shall be placed on each plan sheet where trench excavation will be
				  performed within Department's right-of-way:
COMMUNICATION AND CONTROL CABLES CONNECTED WITH THE
					 OPERATION OF THE STATE WATER PROJECT ARE BURIED ALONG EITHER OR BOTH SIDES OF
					 THE AQUEDUCT/PIPELINE WITHIN DEPARTMENT OF WATER RESOURCES RIGHT-OF-WAY, AS
					 APPROXIMATELY DEPICTED ON THIS PLAN. PRIOR TO ANY EXCAVATION IN THIS AREA, THE
					 CABLE(S) SHALL BE LOCATED AND EXPOSED BY POTHOLING IN THE PRESENCE OF A
					 DEPARTMENT OF WATER RESOURCES FIELD DIVISION REPRESENTATIVE. CALL AT LEAST
					 SEVEN (7) DAYS IN ADVANCE FOR AN APPOINTMENT. ALL EXCAVATIONS WITHIN THREE (3)
					 FEET OF THE CABLE(S) SHALL BE DONE USING HAND-HELD TOOLS
					 ONLY.
(5) The
				  pothole locations shall be shown on the plans. The pothole elevations shall be
				  referenced to the State Water Project's stationing or Milepost.
(6) The following note shall be placed on
				  each plan sheet where trench excavation will be performed within the
				  Department's right-of-way:
ALL TRENCH EXCAVATION SHALL COMPLY WITH THE MOST CURRENT
					 OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION STANDARDS. TRENCH BACKFILL SHALL
					 BE PLACED IN NO GREATER THAN 4-INCH LIFTS IF HAND COMPACTED OR NO GREATER THAN
					 8-INCH LIFTS IF POWER COMPACTED. TRENCH BACKFILL WITHIN DEPARTMENT OF WATER
					 RESOURCES RIGHT-OF-WAY SHALL BE COMPACTED TO 95 PERCENT RELATIVE COMPACTION
					 (ASTM D1557-12).
(7) Plans
				  shall contain the following information:
a)
				  State Water Project Milepost at each crossing, pipeline size and location, and
				  type of material transported.
b)
				  Maximum operating pressure, type of pipe and joints, maximum test pressure and
				  description of test procedures, wall thickness, and carrier pipe
				  classification.
c) Type of
				  sleeve/casing pipe including diameter, joints, and wall thickness.
d) Protective coatings and corrosion control
				  measures.
e) Location of nearest
				  shutoff valve on each side of the crossing.
f) Location and details of thrust
				  blocks.
g) Code(s) used for
				  design.
h) Location including depth
				  of the State Water Project's pipeline, if present, and the communication and
				  control cables.
i) Other existing
				  utility easements or encroachments in the immediate
				  vicinity.
(8) Detectable
				  warning tape shall be required over all trenched utilities and shall be a
				  minimum of eighteen (18) inches above the utility situated within the
				  Department's right-of-way. Subsequent repair or maintenance of the utility
				  shall require replacement of the detectable warning tape.
Warning tapes shall conform to the following
					 guidelines:
a) For potable waterlines,
				  the warning tape shall be a three (3)-inch-wide blue detectable tape imprinted
				  with "CAUTION BURIED POTABLE WATERLINE."
b) For non-potable waterlines, the warning
				  tape shall be a three (3)-inch-wide purple detectable tape imprinted with
				  "CAUTION BURIED NON-POTABLE WATERLINE."
c) For sewer and storm drain lines, the
				  warning tape shall be a three (3)-inch-wide green detectable tape imprinted
				  with "CAUTION BURIED (type) LINE."
d) For gas, oil, and steam chemical lines,
				  the warning tape shall be a three (3)-inch-wide yellow detectable tape
				  imprinted with "CAUTION BURIED (type) LINE."
e) For telecommunications, telephone, and
				  television conduit(s), the warning tape shall be a three (3)-inch-wide orange
				  detectable tape imprinted with "CAUTION BURIED (type) CONDUIT."
f) For electrical, street lighting, and
				  traffic signal conduit(s), the warning tape shall be a three (3)-inch-wide red
				  detectable tape imprinted with "CAUTION BURIED (type)
				  CONDUIT."
(9) Electrical
				  conduits installed within the Department's right-of-way shall be overlaid with
				  three (3) inches of red-dyed concrete, in addition to detectable warning tape
				  as described in subsection
				  8(F)
				  above.
(10) The utility
				  owner/operator shall maintain the pipeline, casing seal, and identification
				  signs in good condition as determined by the Department. Failure to repair
				  problems after notification may lead to encroachment permit
				  revocation.
