The provisions of this chapter apply to permits for the making,
or causing to be made, in any highway, of excavations, and for the
placing, constructing, testing, repairing, changing, monitoring, removing
or abandoning of facilities or encroachments. The provisions of this
chapter also apply to written emergency plans for owners or operators
of pipelines used to convey toxic, corrosive or flammable liquids,
and mandatory membership in a one-call notification system.
(LACC Ord. 3597 Ch. 8 § 801,
1940; LACC Ord. 9349 § 1,
1967; LACC Ord. 11581 § 5,
1977; LACC Ord. 12038 § 4,
1979)
When a one-call notification system is operational in the city,
no person shall maintain and operate a pipeline designed to carry
hazardous substances below the surface of a highway unless said person
is a member of the system. Such person shall provide to the city engineer
such proof as required that said person is a member of the system
in the city. For the purpose of this section, electrical facilities
shall not be considered hazardous.
(LACC Ord. 3597 Ch. 8 § 801.1,
1940; LACC Ord. 12038 § 5,
1979)
Each applicant for an excavation or encroachment permit shall
file with the application a plat in quintuplicate showing the highways
in which the proposed excavation, facility or encroachment will be
placed, together with the exact location and dimensions of the proposed
excavations, or the specifications and characteristics of the facility
or encroachment, together with any other details which the city engineer
requires. When excavations are made for service connections or for
the location of trouble in conduits, cable or pipe, or for making
repairs thereto, the city engineer may waive the filing of a plat.
Approved plats shall become public records.
(LACC Ord. 3597 Ch. 8 § 802,
1940; LACC Ord. 9349 § 1,
1967; LACC Ord. 11581 § 6,

F. Forty-two
inches for electric and natural gas facilities in master plan highways.
(LACC Ord. 3597 Ch. 8 § 802.1,
1940; LACC Ord. 11581 § 7,
1977)
A. After
initial installation under this chapter of any pipeline used or to
be used to carry toxic, corrosive or flammable liquids, such pipeline
shall be subject to a hydrostatic pressure test as provided herein
before it is placed in operation. The duration of the hydrostatic
test for this purpose shall not be less than 24 hours.
B. After
repair or placement of any pipeline used or to be used to carry toxic,
corrosive or flammable liquids, made necessary to repair leaks or
breaks, or replacements made necessary for changes required by improvements
within the roadway, the affected portion of the pipeline shall be
subjected to a hydrostatic pressure test as provided herein before
placing in operation. The duration of the hydrostatic test for this
purpose shall be not less than 24 hours. However, no such test is
required for a minor repair which does not require removal of the
pipeline from operation. If the affected section is isolated and tested
hydrostatically, pressure test of the tie-in welds is not required;
however, tie-in welds shall be examined by radiographic means.
C. No pipeline
subject to this chapter used or to be used to carry toxic, corrosive
or flammable liquids and over ten years of age shall be operated beyond
the successive ensuing 12 month period of time unless retested annually
by a hydrostatic pressure test or other test means acceptable to the
city engineer. The duration of the periodic test for this purpose
shall not be less than four hours.
D. Each
pressure test, either initial or retest, shall be in accordance with
the American National Standard Institute's Code for Pressure Piping,
Liquid Petroleum Transportation Piping Systems (ANSI B 31.4) in its
latest revision. The city engineer may authorize the use of a liquid
petroleum that does not vaporize rapidly (i.e., flash point over 150
degrees Fahrenheit or 66 degrees Centigrade) as a test medium. Pressure
tests after initial installation of pipelines and before they are
placed in operation shall show no unexplained loss. Annual or retest
pressure tests shall not show an hourly loss, for each section of
the pipeline under test at the time, in excess of either ten gallons,
or the sum of one gallon and an amount computed at a rate in gallons
per mile equivalent to one-tenth of the nominal internal diameter
of the pipe.
E. The
city engineer may grant administrative waiver or other relief to an
owner or operator under this chapter as to the periodic pressure testing
of any pipelines as herein provided if owner or operator can demonstrate
that such testing will cause the unreasonable unscheduled shutdown
of plants, terminals, refineries or other facilities of which such
pipelines constitute an integral part.
F. In addition
to the foregoing requirements, any pipeline authorized by this chapter
and subject to pressure testing shall be subjected to a pressure test
by the owner or operator at any time as may be required by the city
engineer in the interest of public safety.
G. Within
30 days after completion of any test made pursuant to the provisions
of this chapter, the owner or operator shall submit a certified report
of such text for the city engineer's review. The report shall show
the date of test, description of portion of pipeline tested (identified
with respect to county highways), and the test data. The report shall
be sufficient in detail to permit analysis of test results and determination
of compliance with the applicable provisions of the ordinance codified
in this chapter or any other applicable ordinance, rule or regulation.
The report shall also contain any other test information as may be
specifically requested by the city engineer.
(LACC Ord. 3597 Ch. 8 § 802.2,
1940; LACC Ord. 12038 § 6,
1979)
Block valves shall be installed on each new main at locations
along the pipeline system that will minimize damage from accidental
product discharge. Said location shall be appropriate for the terrain
and the population density of the area.
(LACC Ord. 3597 Ch. 8 § 802.3,
1940; LACC Ord. 12038 § 7,
1979)
As provided in the American National Standard Institute's Code
for Pressure Piping, Liquid Petroleum Transportation Piping Systems
(ANSI B 31.4) in its latest revision, a cathodic protection system
shall be installed for all new ferrous pipelines used to carry toxic,
corrosive or flammable substances other than utility gases in order
to mitigate corrosion deterioration that might result in structural
failure. The cathodic protection system for all new ferrous pipelines
carrying utility gases shall be installed in accordance with General
Order No. 112-C of the Public Utilities Commission of the state of
California. A test procedure shall be developed by the owner or operator
to determine whether adequate cathodic protection has been achieved
and submitted to the city engineer for approval. Reports of cathodic
protection evaluation in accordance with such approved procedure shall
be made available annually for review by the city engineer.
(LACC Ord. 3597 Ch. 8 § 802.4,
1940; LACC Ord. 12038 § 8,
1979)
A. Each
owner or operator of a pipeline used or to be used to convey toxic,
corrosive or flammable liquids shall have a written emergency plan
approved and on file with the city forester and fire warden. The plan
shall be in accordance with the American National Standard Institute's
Code for Pressure Piping, Liquid Petroleum Transportation Piping Systems
(ANSI B 31.4) in its latest revision.
B. The
plan shall include but not be limited to the following elements:
1. A
"liaison" element for intercommunications between public agencies
and pipeline owners or operators to provide for prompt coordinated
remedial action, and the dissemination of information as to the location
and ownership identification of pipelines based on the best available
records and plans;
2. A
"spill contingency" element to limit the extent of accidental product
discharge by which pipeline owners or operators shall involve themselves
in a cooperative pipeline leak notification emergency action system;
3. A
"leak detection" element by which the pipeline owners or operators
can monitor the flow of their product and can divert, reduce or stop
the flow of said product at the first indication of a product leak;
4. A
"first-on-the-scene emergency containment" element, in cooperation
with other pipeline owners or operators, to be utilized until arrival
of the affected pipeline owner's or operator's personnel. "First-on-the-scene"
costs shall be borne by the owner or operator of the facility, and
shall be reimbursed to the organization effecting the emergency containment.
(LACC Ord. 3597 Ch. 8 § 802.5,
1940; LACC Ord. 12038 § 9,
1979)
Immediately upon completion of the work necessitating the excavation,
facility or encroachment permitted by any permit issued, the permittee
shall promptly and in a workmanlike manner restore the area affected
by his or her activity to a condition satisfactory to the city engineer.
(LACC Ord. 3597 Ch. 8 § 803,
1940; LACC Ord. 9349 § 1,
1967)
A permittee shall refill an excavation in the manner which is
satisfactory to the city engineer and is most effective to accomplish
thorough consolidation and enable the highway to be restored to a
condition equivalent to that in which it was prior to the excavation.
(LACC Ord. 3597 Ch. 8 § 804,
1940; LACC Ord. 9349 § 1,
1967)
Upon completion of the refilling of the excavation, or completion of the cut or fill, the permittee shall so notify the city engineer in writing on a form prescribed by the city engineer. Whenever a plat was required by Section
7.24.030 and there were substantial deviations approved during the work from the dimensions or locations as shown on the plat, the permittee shall transmit to the city engineer a concise "as-built plat" upon completion of his or her work, showing the accurate location, depth and size of the facility or encroachment so laid, removed or abandoned.
(LACC Ord. 3597 Ch. 8 § 805,
1940; LACC Ord. 9349 § 1,
1967; LACC Ord. 11581 § 9,
1977)
Every application shall contain a statement, signed by the applicant,
that if any facility or encroachment placed in the excavation or the
facility or encroachment for which a permit is issued interferes with
the future use of the highway by the general public, then the applicant
and his or her successors or assigns will at his or her own expense
remove or relocate to a location satisfactory to the city engineer
such facility or encroachment. The statement signed by the applicant
will not apply in cases when the applicant has an easement superior
to the highway easement at the time of application and can furnish
evidence when required of such superior easement.
(LACC Ord. 3597 Ch. 8 § 806,
1940; LACC Ord. 9349 § 1,
1967; LACC Ord. 11581 § 10,
1977)
Nothing in this chapter prohibits any person from maintaining
by virtue of any law, ordinance or permit, any facility or encroachment
in any highway, or from making such excavation as may be necessary
for the preservation of life or property if the person making such
excavation applies for a permit not later than the next business day.
(LACC Ord. 3597 Ch. 8 § 807,
1940; LACC Ord. 9349 § 1,
1967; LACC Ord. 11581 § 11,
1977)
The city engineer shall require all lines for the transmission
and distribution of standard television or audio signals to be placed
underground in highways when all power and telephone lines are underground,
and shall also require underground installation in all instances except
where the applicant provides satisfactory proof of permission to use
existing pole lines or where the commission finds that the remoteness
of the area or other conditions render underground installation impractical
or infeasible.
(LACC Ord. 3597 Ch. 8 § 808,
1940; LACC Ord. 9349 § 1,
1967)
The city engineer may establish such requirements as he or she
may find necessary to apply to the work to be done by any person in
order to prevent interference with users of the highway and with holders
of other permits.
(LACC Ord. 3597 Ch. 8 § 809,
1940; LACC Ord. 9349 § 1,
1967)
A. Each
applicant for a permit to abandon in place or remove any facility
or encroachment in the highway shall do so under terms and conditions
prescribed by the city engineer. The permit application shall include
a plat or other suitable means describing the facility or encroachment
to be abandoned or removed, and indicating its exact location. Permission
to abandon a facility or encroachment without removing shall be subject
to removal within one year after the effective date of the abandonment
if the facility or encroachment may interfere with a present or future
public improvement. If it is determined that the facility or encroachment
should be removed, the permittee or its successor in interest shall
remove it at its expense or pay county for the cost of such removal.
Permittee shall leave any abandoned facility or encroachment in a
safe condition.
B. In addition
to the foregoing, abandonment in place of a pipeline used to convey
toxic, corrosive or flammable liquids will be subject to the following
requirements:
1. The
pipeline shall be thoroughly purged of liquids and vapors and filled
with an inert material that will remain in a solid or semisolid state
if any portion of the pipeline is cut or removed in the future.
2. The
permittee shall file a certificate with the city engineer that said
requirements have been complied with and the abandoned pipeline has
been left in a safe condition.
