Calendar Item No. 104 California State Lands Commission Adjourned to August 20, 2012 Central Coastal California Seismic Imaging Project R/V Marcus G. Langseth
2 DCPP PG&E Project Objectives State waters (3 nm limit) Zone 3: Hosgri fault zone Zone 4: Hosgri & Los Osos fault zones Zone 2: Hosgri fault zone & Shoreline, Hosgri, and Los Osos fault intersections Zone 1: Hosgri and Shoreline faults (includes southern extent of Shoreline fault) Obtain Deep, High Resolution, Seismic Imaging of Faults (proposed survey footprint in yellow) White Rock- Cambria & Point Buchon MPAs
3 Project Environmental Impact Report (EIR) Identifies Significant & Unavoidable Impacts ImpactEIR Section Air Emissions due (Air Quality & to Survey Vessels Greenhouse Gases) Noise Impacts to (Biological Marine Mammals Resources – Marine) Marine Protected Areas(Land Use) Commercial & (Land Use & Recreational FishingCommercial Fishing) Impacts remain Significant and Unavoidable after mitigation.
4 # I No Project Alternative CSLC does not approve Project. IIbPhased Survey PG&E conducts part of survey in first year, followed by a delay of some months to a year before conducting second part of the survey. IIIb Three-Loop Configuration * Eliminates northern zone near MBNMS and two MPAs (Zone 3). IIIc Two-Loop Configuration PG&E’s original survey consisting of two “racetracks” (replaced with proposed four-loop Project in January 2012). * Environmentally Superior Alternative in EIR EIR Identifies & Analyzes Alternatives
5 Proposed Project Versus Other Options Proposed Project Years2012 Start date~10/1 End date12/31 # Zones/ MPAs 4 / 3 # days of air guns 41 Total days 82 Pro- posed IIIb Years2012 Start date~10/1 End date12/31 # Zones/ MPAs 4 / 33 / 1 # days of air guns 4134 Total days 8268 IIIb Modified Timing, 3-Loop Years20122012 / 2013 * Start date ~10/1 10/15 Air gun start11/1 End date12/31 # Zones/MPAs3 / 1 # days of air guns 34 *2012Mobilization can begin October 15. Air gun window: November 1 – December 31. Survey ends on or before December 31. 2013If PG&E cannot survey all target faults in 2012 (due to weather, equipment problems, presence of marine mammals, etc.), survey may continue in 2013, as described above.
6 Commission Options (EIR certified on August 14) This concludes the staff presentation. 1) Adopt Mitigation Monitoring Program (Exhibit D). 2) Adopt CEQA Findings & Statement of Overriding Considerations for: Alternative IIIb, Three-Loop Configuration (Environmentally Superior Alternative); OR 3) Approve the Geophysical Survey Permit. Modified Timing Three-Loop Configuration
