1. SURVEY INFORMATION

1.1 DESCRIPTION OR WORK PERFORMED

As part of Pacific Gas & Electric Company’s (PG&E) seismic safety assessment at the Diablo Canyon

Power Plant (DCPP), an ocean bottom seismometer (OBS) system was installed in the nearshore

waters off Pt. Buchon, San Luis Obispo County in July 2013 and recovered in May 2015.

Between May 27 and 29, 2015, Fugro Pelagos, Inc. (Fugro) provided surface and subsurface

positioning services in support of ROV operations in deeper water segments. Wide area DPGS

integrated with Hypack navigational software was used to position the survey vessel in real time.

Subsurface positioning was achieved using the TrackPoint II USBL positioning system integrated with

the surface navigation system. During survey operations, ROV position fixes were logged along the

seismometer cable recovery route.

1.2 DATA COLLECTION DATES, TIMES, WEATHER AND SEA STATE DURING OPERATIONS

Survey operations were conducted during daylight hours. Daily progress reports (DPRs) were

generated for each survey day which included daily events, Quality, Health, Safety, & Environmental

(QHSE) summary, weather conditions, hours worked, and any Health, Safety & Environmental (HSE)

incidents if incurred. Below is a table describing survey dates and weather conditions, as recorded

in the DPRs.

1.3 CHART OF SURVEY AREA

A map of the biological ROV survey route is included at the end of this report.

1.4 SPATIAL INFORMATION RELATED TO SURVEY TRACKLINES

Accompanying and made a part of this report is the digital ArcGIS shapefile depicting the biological

ROV Survey route.

1.5 NATURE AND LOCATION OF ENVIRONMENTAL HAZARDS ENCOUNTERED

No environmental hazards were encountered during survey operations.

1.6 ACCIDENT, INJURY, DAMAGE TO OR LOSS OF PROPERTY

No accidents or injuries occurred during the operations of the project, and no damages or loss of

property was reported.

1.7 OTHER INFORMATION RELATIVE TO THE PERMITTED ACTIVITIES

No other information related to the permitted activities are reported.

2. BIOLOGICAL INFORMATION

California State Lands Commission “Survey Permit PRC 8391 General Permit to Conduct

Geophysical Surveys” states in Section 7, Paragraph h, item iii “MWMs will not be required aboard

vessels conducting survey activites that ultilize, as the only form of geophysical equipment, non-pulse

or non-acoustic generating passive survey equipment (e.g. ROV, magnetometers, gravity meters).”

Therefore no MWMs were present onboard the vessel and information provided in this section are

from observations by the vessel and ROV survey crews.

2.1 ENCOUNTERS WITH WITH MARINE WILDLIFE

The captain of the vessel and all personnel aboard were instructed to visually monitor the area around

the vessel for approaches by marine wildlife. No encounters with marine wildlife were reported duing

the ROV visual inspections.

2.2 SHUT-DOWNS AND SLOW DOWNS

During ROV video operations, no shut-downs or slow downs were required related to proximity of

marine wildlife.

2.3 OBSERVATIONS OF PINNIPED BEHAVIOR

The ship and ROV survey crews were instructed to report any visual observations of Pinnipeds

exhibiting unusual behavor. During the ROV video surveys no unusual Pinniped behavior was

observed or reported.

2.4 COLLISION EVENTS

There were no collision events during the ROV video survey operations.

2.5 EXHIBIT H – MITIGATION MONITORING PROGRAM

In accordance with CSLC regulations, a completed copy of Exhibit H taken from Fugro Geophysical

Permit PRC 8391.9 has been completed with acknowledgements and included in Appendix A.

2.6 MWM MONITORING REPORT

Based on the cooperative efforts of the Project team and vessel crew, no negative Project activity or

transit-related effects to the marine environment were observed during Project activities. The project

activities were in compliance with the mitigation measures outlined in Exhibit H of CSLC issued

geophysical permit and all mitigation measures were implemented. The mitigation measures were

effective in preventing or minimizing the environmental impacts from the PG&E OBS Project ROV

Survey.
