Santa Barbara Channel Coastal Hazards Removal Program and Goleta Beach Caisson Remediation, Ventura and Santa Barbara Counties, California
|Project Name:||Santa Barbara Channel Coastal Hazards Removal Program and Goleta Beach Caisson Remediation, Ventura and Santa Barbara Counties, California|
|Services:||Coastal Facility Permitting and CEQA|
|Client:||California State Lands Commission/ExxonMobil|
Padre provided CEQA documentation and permitting assistance to the California State Lands Commission’s (CSLC) for their comprehensive Santa Barbara Channel Coastal Hazards Removal Program. This program involved the identification of coastal hazards including pier pilings, pipelines, power cables and wells along the coastline of Ventura and Santa Barbara Counties. Decommissioning plans were prepared for each of the identified hazards with the assistance of a demolition contractor. Once these decommissioning plans were completed, Padre conducted a site-specific review and environmental analysis of the potential impacts associated with the proposed activities. Based upon this analysis, an Initial Study/Mitigated Negative Declaration (IS/MND) was prepared.
As part of the Santa Barbara Channel Coastal Hazards Removal Program, ExxonMobil conducted a project that involved removal of remnants of previously abandoned exploratory drilling piers on a public beach west of Santa Barbara, California. These remnants included steel reinforced concrete drilling foundations and steel and wood piling stubs. These exposed steel members were considered by ExxonMobil and the CSLC to be a public safety hazard.
Working with the CSLC, ExxonMobil and its demolition contractor, Padre prepared and submitted supporting permit applications to the California Coastal Commission, U.S. Army Corps of Engineers, RWQCB and the County of Santa Barbara. The applications included a detailed description of the remedial actions being proposed, as well as supporting environmental information needed by the agencies to process the applications. Key issues associated with this project included the need to cross an environmentally sensitive slough mouth with heavy equipment as well as working with heavy equipment on a public beach within the constraints of tidal action and daylight conditions. Once permits were received for the project, Padre provided onsite environmental compliance monitoring for the project and site restoration services.Padre will be working with the CSLC in 2019 to identify additional hazards along the coast for future removal.
Post 4H Platform Abandonment - Shell Mounds Deposition, Santa Barbara County, California
|Project Name:||Post 4H Platform Abandonment - Shell Mounds Deposition, Santa Barbara County, California|
|Services:||Coastal Facility Permitting|
The professional staff of Padre prepared the technical and environmental clearance needed to fulfill permitting requirements for the permanent abandonment and removal of four offshore platforms (collectively known as the 4H platforms; including platforms Hope, Hilda, Hazel, and Heidi), and associated oil and gas pipelines located in state waters off the eastern Santa Barbara County coast in 1996. Permit-related documentation prepared included:
- Biological resource assessment focusing on marine and terrestrial flora and fauna inhabiting the waters surrounding the affected platforms and onshore pipeline regions;
- Assessment of the potential impacts because of project activities;
- Mitigation measures;
- Evaluation of seafloor conditions below the platforms to determine the extent and composition of discharged drilling-fluids and drilling muds and cuttings (analysis of current speeds and directions in the Santa Barbara Channel aided in the calculation of the extent and duration of turbidity originating from disturbance of sediments during abandonment operations and provided insight as to the projected direction of flow in the event of an oil spill during abandonment operations); and
- Air emission analysis of both criteria air pollutants and evaporative pollutants associated with equipment operations.
Following completion of the offshore decommissioning activities, Chevron conducted the required trawl test to demonstrate site clearance at the former platform sites. During these activities, it was determined that Chevron would be unable to meet this permit condition and that an amendment to the State Lands Commission (CSLC) and California Coastal Commission (CCC) permits would be necessary.
Encina Marine Oil Terminal Decommissioning Planning, Carlsbad, California
|Project Name:||Encina Marine Oil Terminal Decommissioning Planning, Carlsbad, California|
|Services:||Coastal Facility Decommissioning Planning, CEQA Compliance, Permitting Assistance, and Compliance Monitoring|
|Client:||Cabrillo Power I LLC, California State Lands Commission, and Curtin Maritime Corporation|
Padre and its subconsultant Longitude 123 prepared a Project Execution Plan (PEP) on behalf of Cabrillo Power I LLC addressing the decommissioning of its Encina Marine Oil Terminal (MOT). The MOT historically supported electrical energy production at the Encina Power Station (EPS) in Carlsbad, California and is partially located offshore within a State Lease area. The PEP is designed to provide for the decommissioning of the MOT in a manner that is satisfactory to the California State Lands Commission (CSLC) and will allow for a lease termination agreement.
The PEP includes a detailed description of project setting, potential decommissioning project activities including alternative scenarios. The PEP also includes an environmental impact assessment as well as supporting documentation and plans provided to maximize safety and minimize potential environmental impacts. These plans were prepared by Padre and include:
- Marine Safety and Anchoring Plan;
- Marine Wildlife Contingency Plan;
- Oil Spill Response Plan.
Additionally, the PEP provides information used to support the preparation of the required California Environmental Quality Act (CEQA) documentation and regulatory permit applications.
After submittal of the PEP and approval of the project design by the CSLC, Padre assisted the CSLC with the preparation of a CEQA compliance document for the Project. The Mitigated Negative Declaration may be downloaded at: http://www.slc.ca.gov/Info/CEQA/Cabrillo.html
The MOT facilities are located within the jurisdictions of multiple federal, state and local agencies. After the completion and approval of the CEQA documentation, Padre assisted Cabrillo Power I LLC with the preparation of permit applications that were submitted to the California Coastal Commission (CCC), United States Army Corps of Engineers (USACOE) and San Diego Regional Water Quality Control Board (RWQCB). These included a CCC Coastal Development Permit application, Preconstruction Notification Package for coverage under the USACOE Nationwide Permit Program, and RWQCB application for Clean Water Act Section 401 Water Quality Certification. Padre also assisted with coordination of a Right of Entry Permit from the California Department of Parks and Recreation.
Once permits were received, Padre assisted Cabrillo Power I LLC with development of a CEQA mitigation and permit condition tracking document. Padre also assisted (under a separate contract) the selected contractor, Curtin Maritime Corporation, complete their Contractor Work Plan for the project which was approved by the CSLC in 2017.
Presently, Padre is assisting Cabrillo Power I LLC with certain tasks associated with mitigation and project permit condition compliance monitoring and reporting. This includes offshore monitoring for the protection of marine wildlife, and other environmental compliance measures, as well as preparation of periodic compliance monitoring reports. Upon completion of the project Padre will prepare a final mitigation and permit conditions compliance summary report on behalf of Cabrillo Power I LLC for submittal to the CSLC.
Beta Offshore - Platform Eureka to Platform Elly Intrafield Replacement Pipelines Project, Los Angeles Basin, California
|Project Name:||Beta Offshore - Platform Eureka to Platform Elly Intrafield Replacement Pipelines Project, Los Angeles Basin, California|
|Services:||Coastal Facilities Permitting and Environmental Compliance|
In 2011, Beta Offshore proposed to replace their existing 12-inch gross fluids and 10-inch water injection pipelines that run between Platform Elly and Platform Eureka in the Beta Unit located offshore of the Los Angeles Basin. Padre assisted Beta Offshore with the development of the project-related permit application package including site specific biological and geological site surveys. The proposed project received one of the first project approvals issued by the recently reorganized Bureau of Ocean Energy Management (BOEM) and Bureau of Safety and Environmental Enforcement (BSEE).
Once approved, pipeline installation was conducted utilizing a dynamically-positioned vessel to avoid anchoring impacts. Padre assisted with development and implementation of the Project Compliance Monitoring Program during offshore pipeline installation activities and provided marine mammal monitoring throughout construction.
