Prepared by Deborah S. Traffenstedt, Senior Planner
DATE: May 24, 1993 (CC Meeting of 6 -2 -93)
SUBJECT: CONSIDER CITY COMMENTS ON DRAFT ENVIRONMENTAL IMPACT
REPORT (EIR) FOR PACIFIC PIPELINE PROJECT (LEAD AGENCY:
CALIFORNIA PUBLIC UTILITIES COMMISSION).
Background
The City of Moorpark has received
Draft EIR. Written comments are
Utilities Commission (CPUC) by June
scheduled for June 17, 1993, at the
Building, and will begin at 10:00 a
being held on different days in the
Burbank, and Santa Barbara.
L copy of the above referenced
due to the California Public
18, 1993. A public hearing is
Ventura County Administration
.m. Public hearings are also
Cities of Los Angeles, Carson,
The proposed project under consideration by the CPUC is the
application of Pacific Pipeline System, Inc., to build a 171 -mile
long, 20 -inch crude oil pipeline along the Southern Pacific
Railroad right -of -way from the Gaviota Marine Terminal in western
Santa Barbara County to refineries in south Los Angeles County.
The proposed pipeline route is shown on Draft EIR Figure ES -1
(attached). While the proposed project is not expected to impact
the City of Moorpark, an alternative alignment, called the Southern
Route Alternative, would result in significant adverse impacts to
the City and its residents.
The alignment for the Southern Route alternative varies from the
proposed project for a distance of 59 miles from the City of
SanBuenaventura to the City of Burbank and predominantly follows
the Southern Pacific right -of -way through the Cities of Oxnard,
Camarillo, Moorpark and Simi Valley; passes through Chatsworth and
other portions of the San Fernando Valley in the City of Los
Angeles; and rejoins the proposed route in Burbank (see attached
Draft EIR Figure ES -1). Roadways in the City of Moorpark that
would be crossed by the Southern Route Alternative are Gabbert
Road, Moorpark Avenue, Spring Road, and Los Angeles Avenue. To
minimize pipeline construction impacts, the proposal is to bore
underneath roadways, highways, and other pipelines and utilities;
however, the boring procedure could require temporary closure of a
portion of a road, during off -peak hours.
The Honorable City Council
May 24, 1993

Discussion
Within the City of Moorpark, the proposed Southern Route
Alternative has the potential to result in significant impacts that
cannot be fully mitigated, including vegetation and wildlife
impacts (primarily along the Arroyo Simi), construction noise
impacts (to schools and residences located in the immediate
vicinity of the railroad right -of -way), public service impacts in
the event of an oil spill, and environmental contamination of soils
and /or creeks in the event of an oil spill. The specter of a spill
near the residential uses must be specifically addressed in any
mitigation measures proposed. The Draft EIR summary tables, which
identify impacts and proposed mitigation measures, are attached.
The Southern Route Alternative is a technically feasible
alternative and would meet the applicant's objectives; therefore,
staff has been working with other affected jurisdictions and the
EIR consultants, since November 1992, to ensure that the impacts of
the Southern Route Alternative are adequately addressed. If the
Southern Route Alternative were to be selected, the applicant would
need to obtain a conditional use permit, a franchise agreement, and
encroachment permits from the City of Moorpark.
Staff ' s primary concern with the Southern Route Alternative is that
it could affect future use of the railroad right -of -way for an
additional commuter rail link between Ventura and Los Angeles. The
Southern California Regional Rail Authority ( SCRRA) is planning
additional rail sidings and /or double track alignments between the
Cities of Moorpark and Burbank. Due to the preliminary nature of
the proposed rail project, it has not been determined if placement
of the pipeline would preclude or conflict with future rail
development due to right -of -way space constraints. If the
applicant decides to proceed with the Southern Route Alternative,
pipeline location plans would need to be submitted to SCRRA and the
Southern Pacific Railroad, and Right -of -Entry Agreements would need
to be obtained. All responsible agencies would need to make a
determination prior to permit approval as to the adequacy of the
EIR and whether any additional environmental clearance document is
required.
Following are other comments that staff intends to include in a
comment letter to the CPUC:
Section C.9.3.2, Noise, Environmental Impacts and Mitigation
Measures - Noise impact information should be provided for the
Community High School in the City of Moorpark. The location of the
Community High School is on Condor Drive, north of the railroad
right -of -way (approximately Milepost 25.0). As an additional noise
comment, the Draft EIR provides minimal information regarding noise
impacts to residential receptors adjacent to the railroad right -of-
way, and the City may require supplemental noise impact information
The Honorable City Council
May 24, 1993
Page 3
Table C.9 -12, Noise Impact Data for Southern Route Alternative -
Change "Moorpark High School" to "Casey Road School Facilities"
(Milepost 23.5) and add the "Community High School" (approximately
Milepost 25.0) and noise impact information.
Table C.9 -10, Noise Data for Southern Route in Ventura County -
Change "Moorpark High School" (Milepost 23.5) to "Casey Road School
Facilities" and change "Los Angeles Avenue" to "Los Angeles Avenue
and Moorpark Avenue "; change "Shaparral Middle School" to
"Chaparral Middle School" (Milepost 23.5) and change "Los Angeles
Avenue" to "Los Angeles Avenue and Moorpark Avenue ". Add the
"Community High School" (approximately Milepost 25.0) and
applicable noise impact information for that school.
Section C.15.3.2.1, Transportation and Traffic, Construction
Impacts - The EIR should specifically address the potential for
construction related damage to AMTRAK /METROL INK stations and /or
parking lots and identify appropriate mitigation measures.
Section C.15.3.2.1, Transportation and Traffic, Mitigation Measures
for the Impact of Construction - A mitigation measure should be
included that is similar to T -11 for the proposed project (i.e.,
require that rail operations compatibility issues be coordinated
with SCRRA and the Southern Pacific Railroad). An additional
mitigation measure should be included that ensures that the access
from AMTRAK /Metrolink parking lots to station platforms will not be
completely blocked by construction activities. The requirements of
the SCRRA, as stated in their letter dated March 24, 1993, should
be referenced in this section, so as to require incorporation into
a mitigation monitoring program (if the Southern Route Alternative
were to be approved as the project).
C.15.3.2.2, Transportation and Traffic, Operational Impacts - This
section should reference mitigation measure T -12 as being
applicable in the case of an oil spill during the operation phase.
RECOMMENDATION
Direct staff to prepare a comment letter on the Draft EIR.

EXECUTIVE SUMMARY
6. IMPACT SUMMARY TABLES
The Impact Summary Tables which follow are a complete, condensed presentation of the significant
environmental impacts and mitigation measures for the Proposed Pacific Pipeline Project and the Proposed
Alternatives. Full descriptions of the Proposed Project and each of the Alternatives can be found in Part
B of this EIR. The complete environmental analyses, along with the proposed mitigation measures for
the Proposed Project and for each of the Alternatives are set out fully in Part C.
The Impact Summary Tables are organized first according to impact class and within each class according
to issue area in the same order as presented in Part C. Reading from left to right across the tables, (1)
each impact is described briefly, (2) the phase of the project life in which the impact would occur is
given, (3) the extent and scope of the impact is explained, (4) the mitigation measure is presented, and
(5) the residual effect of the impact (i.e., after application of recommended mitigation measures) is
identified. When no residual impact occurs or no mitigation measure is specified, this is so indicated.
In -depth discussion of the five summary areas on the tables is located within Part C. The issue areas are
presented there in the same order as they are found on the Summary Tables. Note, however, that the
issue area numbers differ between the tables and Part C. This is due to the inclusion of an Introduction
to Part C, numbered as C.1, forcing the actual issue areas to begin with C.2 (the tables begin with the
number 1). The following Tables summarizes the significant impacts. Part C presents a detailed
description of these impacts as well as adverse but non - significant impacts (Class III).
C The significance criteria used to classify impacts for each issue area and explanations of the meanings of
"short term," "long term," "local," and "regional," which differ somewhat among issue areas, are
provided by issue area in Part C. These appear early in the full text discussion of each issue area in Part
C. The impacts are then spelled out in detail, followed by their numbered mitigation measures. Next
details are presented for cumulative impacts and mitigation measures and unavoidable significant impacts.
Lastly, a Mitigation Monitoring Plan, which provides full details on each mitigation measure and the
name of the agencies and parties responsible, is presented at the end of each issue area analysis in Part C.
The Mitigation Monitoring Plans provide the full spectrum of measures proposed by this study, including
some that are associated with Class III impacts and not shown in the following tables.
Further explanation of the organization of Part C may be found in its Introduction, Section C. The
Impact Summary Tables, as presented ahead, are a stand -alone document and may be viewed as a
convenient compilation of the core data presented in the EIR.

Attention: Mr. Lou Merzario
Dear Mr: Walker:
PROPOSED PACIFIC PIPELINE SYSTEM
Reference your March 8, 1993 letter concerning whether Southern California Regional Rail
Authority (SCRRA) would have any conflict between the routing of the proposed Santa Paula
Pacific Pipeline System or the Southern Pipeline Route alternative and the possible future
addition of siding and/or a second track to the existing SCRRA and Southern Pacific rail lines.
Please find attached copies of (SCRRA) railroad track charts depicting conceptual preliminary
proposed locations of future double tracks (shown colored red) from Santa Clarita to Los
Angeles and Moorpark to Burbank Junction to Los Angeles. Pacific Pipeline Route along
Southern Pacific's Santa Paula Line to Santa Clarita should have future track and two mile long
siding tracks proposed every five miles and Santa Clarita to Los Angeles should have double
tracks. Exact location to be determined upon review of proposed pipeline location plans. These
proposed double track locations have not been field reviewed or confirmed to be the final
proposed track locations. Upon receipt of Pacific Pipelines proposed pipe line location plans,
SCRRA and Counties will review said plans and submit all comments, concerns, objections and
SCRRA's final proposed sidings and/or double track alignments. Then Pacific Pipelines would
be required to modify their proposed pipeline location, if it conflicts with SCRRA and or
County's proposed sidings and or double track alignments.
Listed below are (SCRRA's) comments pertaining to Pacific Pipeline's proposed pipeline,
concerning location, standards and specifications, construction procedures, and proposed
relations with Railroad (SCRRA).
