045-9 Wyo. Code R. §§ 9-4 - Specific Provisions
(a) The following
shall apply to all facility types:
(i) Design and construction of all carrier
pipe and casing pipe shall comply with the most current provisions of federal
and state laws, rules and regulations, industry standards, and the provisions
of this regulation.
(ii) Casing of
crossing pipelines is not required if the carrier pipe is of heavy wall
thickness and the line is cathodically protected. The heavy wall thickness
portion of the line, or casing if used, shall extend to the highway
right-of-way line to allow for future widening of the roadway.
(iii) Bore and receiving pits shall be
located as close to the highway right-of-way line as possible.
(iv) Bore and receiving pits shall not be
located in the median strips of divided highways where the median is less than
120 feet wide, unless specifically approved by the department's engineer
because of extenuating circumstances.
(v) Abandoned or incomplete bores shall be
backfilled and plugged as directed by the department's engineer.
(vi) Pipeline crossings shall be as near to
perpendicular to the roadway centerline as practical.
(vii) Vent pipes shall be located as close as
possible to the right-of-way line. If vent pipes lie within the clear roadway
recovery area, they shall be of a breakaway design.
(viii) Line markers that fall within the
clear roadway recovery area shall be of a breakaway design.
(ix) If support facilities are located
immediately adjacent to the highway right-of-way and require periodic access,
an approach and gate shall be applied for at the department's district office
by separate procedure.
(b) The following shall apply to
transmission lines:
(i) Parallel
encroachments of transmission lines shall not be allowed within the No
Access line of fully access controlled interstate highways.
(ii) Parallel encroachments of transmission
lines shall not be allowed within the median strips of divided
highways.
(iii) Parallel
encroachments of transmission lines may be allowed along partially access
controlled highways at the discretion of the director or the commission if
special and unique circumstances exist, and if such parallel encroachment does
not affect the safe operation, design, construction, reconstruction, and
maintenance of the highway.
(iv)
When a parallel encroachment is allowed for transmission lines, the line shall
be located as close to the highway right-of-way line as possible and no closer
to the road bed than 50 feet from the adjacent edge of the traveled way as
delineated by the edge-line paint stripe.
(v) When a parallel encroachment is allowed,
the facility shall be marked with line markers every 1,000 feet placed as
nearly as practical over the top of the transmission line. A continuous colored
tracer tape shall be placed 18 inches above the top of any pipe that falls
within the right-of-way.
(vi)
Transmission facilities shall not be attached to any bridge or other highway
structure.
(vii) A Wyoming-licensed
professional engineer shall review and approve above-ground transmission
support structures used to cross rivers.
(viii) The minimum depth of cover for
parallel transmission lines shall be 48 inches below natural ground and/or
below the roadway ditch flow line. The minimum depth of cover for parallel
facilities closer to the traveled way than the designated 50 feet minimum shall
be 72 inches below natural ground and/or below the roadway ditch flow line. The
minimum depth of cover for all crossing transmission lines shall be 120 inches
below natural ground and/or below the roadway ditch flow. If the minimum depth
of cover is not practical because of natural conditions, the applicant shall
consider additional protective measures (such as concrete encasement or using a
concrete cap or slab or other protective measures) as part of the license
application.
(ix) Transmission line
support facilities such as storage tanks, compressors, valves, clean-out traps,
cathodic protection fields and rectifiers, and similar facilities shall not be
located inside the highway right-of-way unless extenuating circumstances exist
and the director or the commission specifically approves the proposed
location.
(x) If extenuating
circumstances or site specific conditions prove that a cathodic protection
groundbed must be placed on highway right-of-way to be effective (other than on
interstate highways), such an installation may be approved if the applicant
presents sufficient justification.
(c) The following shall apply to
gathering lines:
(i) Parallel
encroachments of gathering lines shall not be placed within the highway
right-of-way. The number of gathering lines crossing the highway right-of-way
shall be held to a minimum by placing large casing pipes in a few locations and
running several gathering lines through them.
(ii) The minimum depth of cover for crossing
gathering lines shall be 36 inches below natural ground and/or below the
roadway ditch flow line. If the minimum depth of cover is not practical because
of rock, the applicant shall consider additional protective measures (such as
concrete encasement or using a concrete cap or slab or other protective
measures) as part of the license application.
(iii) Gathering line support facilities such
as storage tanks, valves, clean-out traps, compressors, and similar facilities
shall not be located on the highway right-of-way.
(iv) If extenuating circumstances or
site-specific conditions prove that a cathodic protection groundbed must be on
highway right-of-way to be effective (other than on interstate highways), such
an installation shall be approved if the applicant presents sufficient
justification.
(v) Line markers
shall be located as close as possible to the right-of-way line.
(d) The following shall apply to
distribution lines:
(i) Distribution systems
may be allowed to encroach parallel to, or to cross, the highway
right-of-way.
(ii) The minimum
depth of cover for distribution lines, whether in urban or rural areas, shall
be 36 inches below natural ground and/or below the roadway ditch flow line. If
the minimum depth of cover is not practical because of rock, the applicant
shall consider additional protective measures (such as concrete encasement or
using a concrete cap or slab or other protective measures) as part of the
license application.
(iii) Neither
distribution system pressure regulators, whether in huts or in vaults, nor
metering equipment shall be located on highway right-of-way unless extenuating
circumstances exist and the department specifically approves the proposed
location.
