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 Page 2 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.

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. 04 -26-93 ES -59 IMPACT SUMMARY TABLES CLASS I Class 1 Impacts: Significant, Cannot Be Mitigated To A Level That Is Not Significant Issue Area/Pro �ct or Alternative/impact Projeq Scope Mitigation Measure Residual Impact Alit QUALITY Promised Pro ec Cajon Reversal of Four Corners 'otrero Alternatives I .

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).
