5.0 MITIGATION MONITORING PROGRAM1
The California State Lands Commission (CSLC) is the lead agency under the California2
Environmental Quality Act (CEQA) for the Cabrillo Power I LLC Encina Marine Oil3
Terminal Decommissioning Project (Project). In conjunction with approval of this4
Project, the CSLC adopts this Mitigation Monitoring Program (MMP) for implementation5
of mitigation measures (MMs) for the Project to comply with Public Resources Code6
section 21081.6, subdivision (a) and State CEQA Guidelines sections 15091,7
subdivision (d) and 15097.8
The Project authorizes Cabrillo Power I LLC (Applicant) to decommission the existing9
non-operational Encina Marine Oil Terminal (MOT), which is part of the Encina Power10
Station (EPS), in accordance with the terms and conditions of its existing CSLC Lease11
PRC 791.1.12
5.1 PURPOSE13
It is important that significant impacts from the Project are mitigated to the maximum14
extent feasible. The purpose of a MMP is to ensure compliance and implementation of15
MMs; this MMP shall be used as a working guide for implementation, monitoring, and16
reporting for the Project’s MMs.17
5.2 ENFORCEMENT AND COMPLIANCE18
The CSLC is responsible for enforcing this MMP. The Project Applicant is responsible19
for the successful implementation of and compliance with the MMs identified in this20
MMP. This includes all field personnel and contractors working for the Applicant.21
5.3 MONITORING22
The CSLC staff may delegate duties and responsibilities for monitoring to other23
environmental monitors or consultants as necessary. Some monitoring responsibilities24
may be assumed by other agencies, such as affected jurisdictions, cities, and/or the25
California Department of Fish and Wildlife (CDFW). The CSLC and/or its designee shall26
ensure that qualified environmental monitors are assigned to the Project.27
Environmental Monitors. To ensure implementation and success of the MMs, an28
environmental monitor must be on site during all Project activities that have the potential29
to create significant environmental impacts or impacts for which mitigation is required.30
Along with the CSLC staff, the environmental monitor(s) are responsible for:31
• Ensuring that the Applicant has obtained all applicable agency reviews and32
approvals;33
Mitigation Monitoring Program
Encina MOT Decommissioning 5-2 December 2015Project MND
• Coordinating with the Applicant to integrate the mitigation monitoring procedures1
during Project implementation (for this Project, many of the monitoring2
procedures shall be conducted during the deconstruction phase); and3
• Ensuring that the MMP is followed.4
The environmental monitor shall immediately report any deviation from the procedures5
identified in this MMP to the CSLC staff or its designee. The CSLC staff or its designee6
shall approve any deviation and its correction.7
Workforce Personnel. Implementation of the MMP requires the full cooperation of8
Project personnel and supervisors. Many of the MMs require action from site9
supervisors and their crews. The following actions shall be taken to ensure successful10
implementation.11
• Relevant mitigation procedures shall be written into contracts between the12
Applicant and any contractors.13
• For this Project, a marine wildlife training seminar (under MM BIO-1: Marine14
Wildlife Contingency Plan (MWCP)) for all Project personnel working in the15
marine environment would be held as part of a Project kickoff meeting wherein16
Project mitigation would be discussed.17
General Reporting Procedures. A monitoring record form shall be submitted to the18
Applicant, and once the Project is complete, a compilation of all the logs shall be19
submitted to the CSLC staff. The CSLC staff or its designated environmental monitor20
shall develop a checklist to track all procedures required for each MM and shall ensure21
that the timing specified for the procedures is followed. The environmental monitor shall22
note any issues that may occur and take appropriate action to resolve them.23
Public Access to Records. Records and reports are open to the public and would be24
provided upon request.25
5.4 MITIGATION MONITORING TABLE26
This section presents the mitigation monitoring table (Table 5-1) for the following27
environmental disciplines: Aesthetics, Biological Resources, Cultural Resources,28
Hazards and Hazardous Materials, Hydrology and Water Quality, Noise, and29
Transportation/Traffic. All other environmental disciplines were found to have less than30
significant or no impacts and are, therefore, not included below. Additionally, Applicant-31
proposed measures (APMs) would be implemented, as feasible, to further minimize less32
than significant impacts for the following environmental disciplines: Air Quality,33
Biological Resources, Greenhouse Gas Emissions, and Utilities and Service Systems.34

These APMs are included here for the purpose of tracking. The table lists the following1
information by column:2
• Potential Impact (impact number, title, and impact class);3
• Mitigation [or Applicant-Proposed] Measure (full text of the measure);4
• Location (where impact occurs and mitigation measure should be applied);5
• Monitoring/Reporting Action (action to be taken by monitor or Lead Agency);6
• Timing (before, during, or after construction; during operation, etc.);7
• Responsible Party; and8
• Effectiveness Criteria (how the agency can know if the measure is effective).9
