Dear Mr. Meyers:

Pacific Gas and Electric Company (PG&E) is conducting a License Renewal Feasibility Study to determine if it is feasible to renewal the Diablo Canyon Power Plant operating licenses.

The purpose of this letter is to request a search of the NAHC's sacred lands file and a list of local Native Americans with an interest in this area. Any information you can provide for this project area would be helpful.The current operating licenses expire in 2024 and 2025 for Units 1 and 2, respectively.

If PG&E decides to pursue license renewal, based on the results of this feasibility study, the operating license would extend for an additional 20 years to 2044 and 2045. The decision to pursue license renewal has not yet been made.As part of the license renewal process, NRC requires potential applicants to "assess whether any historic or archaeological properties will be affected by the proposed project." NRC may also request an informal consultation with your office at a later date under Section 106 of the National Historic Preservation Act of 1966, as amended (16 USC 470), and under Federal Advisory Council on Historic Preservation regulations (36 CFR 800). By contacting you during the feasibility study, we hope to identify any issues that need to be addressed or provide any information your office may need to expedite the potential NRC consultation.

Diablo Canyon Power Plant (DCPP) is located within the PG&E owner-controlled area, which consists of approximately 760 acres of land located in San Luis Obispo County, adjacent to the Pacific Ocean and roughly equidistant from San Francisco and Los Angeles. It is located directly southeast of Montana de Oro State Park and is approximately 12 miles southwest of the city of San Luis Obispo, the county seat and the nearest significant population center (Figure 1). The DCPP is located on the Port San Luis, Ca 7.5' USGS Quadrangle in the unsectioned area of Canada De Los Osos Y Pecho Y Islay Land Grant in Township 31 South, Range 10 East.Three transmission lines connect the power plant to the regional grid, and are thus relevant to the License Renewal Feasibility Study (Figure 3.1-2). They include:

Diablo-Mesa

-One double-circuit line was connected to an existing Morro Bay-Mesa line 10.25 miles from DCPP with an 80-ft. right-of-way width.* Diablo-Gates

-One single-circuit line was connected to the Gates Substation in Fresno County 79 miles northeast of DCPP with a 350-ft. right-of-way width.* Diablo Midway #2 and 3 -Two single-circuit lines were connected to the Midway Substation in Kern County 84 miles southeast of DCPP with a combined right-of-way width of 400 ft.In total, there are approximately 170 miles of corridor that occupy approximately 4,500 acres. The corridors pass primarily through foothills sand rolling land. In addition, there are parcels of land that are agricultural and forest land. In addition to an overview map (Figure 2.1), a table has been created providing location data for each transmission line (Figure 3).PG&E does not expect continued DCPP operations to adversely affect cultural resources in the APE, as PG&E has no plans to alter current operations or disturb any land for the proposed project. No construction along any of the transmission lines is planned. Maintenance on the transmission lines would continue as currently performed.

If you have any questions or concerns regarding this project please feel free to call me (916) 201-8571.After your review, we would appreciate your input detailing any concerns you may have about cultural resources in the current APE.Thank you for taking the time to review this project.Best Regards, Maggie Trumbly Cultural Resource Specialist Enclosure (2 Maps and a Table)

NATIONAL SCIENCE FOUNDATION 4201 WILSON ,BOULEVARD ARLINGTON, VIRGINIA 22.230 September 18, 2012 -H------Milford Wayne Donaldson 21 I Stat'e Historic Preservation Officer , P] ! 0 iN office. of Historic Preservation 1725 23rd Street, Suite 1O0 0 OHP Sacramento, CA 95816 *.....Re: Central Coastal California Seismic Imaging:Project

Dear Mr. Donaldson,

The ;National Science Foundation. (NSF) is initiating consultation with the State Historic preservation officer (SHPO) regarding the undertaking referenced

above. We are consulting with you in accordance with 36 CFR Part 800, the regulations implementing Section 106 of the ;National Historic PreserVation Act. Specifically, we .are consulting With you concerning the determination of the Project's area of potential effect (APE), the adequacy of the inventory effort and finding of effect for the proposed undertaking; Enclosed you will find the following materials in support of our present consultation effort: 1. Attachment 1: Project Description

2. Attachment 2: Cultural ResOurces inventory Report (Howes, Haydu and Price,2012)

a. Vidinity, Location and APE maps (Figures 1,3, 4, 5 and 6);b. Native American consultation documents (Appendix A);cO. Cultural Resource LocationMaps (Appendix B); and d. Site .Records (Appendix C).The NSF, in cooperation with Pacific Gas and Electric Company (PG&E), proposes to coniduct :seismic imaging :studies in the vicinity of the Diablo Canyon Power Plant (DCPP) and :known offshore fault.zones. The Project would be, conducted along the central coast of California, from just north of Cayncos down to San Luis Bay,. in :San 'Luis Obispo County (Figure I of Attachment 2). The prop~osed Project would encompass a largeo ffshore area (1,0'175 kilometers 2 / 39:2;8 miles 2) and would also involve, onshore and nearsho'e activities.

As proposed, NSF and PG&E would mobilize Ocrtober !15 :and: conduct the offshore survey b~tween Nqovember 1 and December 31, 201!2. Survey activities Would be conducted 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months per day and 7 days per w~eek. As a result~of the on going consultation processes with National Marine Fisheries ServiCe under the Marine. Mammal Protection Act and the Endangered.

Species Act,: the project plan has beon revised to accommodate their guidance that proposed activities occur over two years rather than one.The Project is. being undertaiken due to public .concerns with operating a nuclear power plant in a seismically active area of California after the Fukushima Daiichi emergency.

The seismic studies will provide: additional insight concerning any reiationships or connections beOtween the. known faults a's well as enhance knowledge of offshore faults near DcPP. PG&E will obtain as 'much seismic information as possible, while minimizing, environmental impacts consistent w'ith the p~ermits and authorizations reqluired by federal, state, and local :agencies.

to conduct the .studies.

The objectives of the proposed high energy 3D seismic survey are: ,,Record highresolution wide 2D and 3D seismicoreflection profiles of major geologic structures and fault zones :in the vicinity of DCPP;' Obtain imp?,ov~d deep.(>1 kmn. [>0,6 mii) imaging of the Hosgri and Shoreline fault.zones in the vicinity o'f the DCPP to constrain'fault geometry;.D Obtain improved (>lkm [>0.6 mi] depth) imaging of the intersection of the Hosgri and Shoreline fault z:ones near PointBuchon; SObtain improved (>1 kcm [>0.6 mai])imaging of the intersection of the Sah Simeon and IHosgri fault zones near Point Estero; and Augment current regional seismic data base for suibsequent use. and analysis.The project components

are su~mmarzed be low. Please refer to the attached project description for additional information,.

For offshore activities, the Project proposes conduct 3D .seismic .surveys using a ;geophysical survey vessel. The primary vessel for survey operations would be the R/V Marcus G. Langseth, which is owned bY NSF. The RNV Lanigseth Woutld a series of sound-generating air guns and sound-recording hydrophonies along pre-.determined shore-parallel and Shore-pe~rpendietilar transects to conduct deep (10.to 15 :km [6 :to9 rai) seismic reflection profiling of major geologic structures and fault zones in the.vicinity of DCPP.- In addition to the R/VLangs eth, other~marine vessels would be uSed as-support Vessels to monitor marine wildlife activity and prevent gear entanglement With any obstructions.

Nearshore activities would. include the placement of geophones along the ocean floor off the coast and adjacent to DCPP propetty.

The geophones would be strung together by cables and plac.ed along five shore-perpendicular' transects.

The .geophones would be Secured the ocean bottom with the use oera clump Weight or similar device. NMFS has recommended the project be implemnented over a two year period..As a result, approximately 12 geophones wouild be deployed in .201i2, and the majority of onshore activities and geophon~e deployment would occur, in 2013.onshor'e activzities Would include ,the. use of seismic sound sources...Sound sources w~ould be geneiated from-two types of seismic source.,vehicles:

VibroseisTM and accelerated weight drop (AWD) trucks.

and AWD trucks would only be operated on DCPP property along predetermined transects that follow existing toads, Vehicle-mounted sound sources Would excluded from cultural resource.sites,. except where established roads :already pass through sites. Sound .sources within cultural sites would be generated by hand-placing a metal Plate on~theground and striking it-with a sledge~hammer.

Onshore ,activties would also include the placement .of ge0phones (recording devices) along the .seismic sound source, corridors at.DCPP and wouild extend 'onto the adjacent Montana de Oro State.Park property.The geophones would be carried !by and secured to the ground surface using a five-inceh spike located at the bottom of the device¢. The Project Description .incorporates an .applicant proposed measure (APM 23) that provides .for cultural resource, moniitors to accompany'each field team dulring deployment of survey equfipment aind seismic testing to .ensure resource protectioni.

The proposed APE, for this project includes :the offshore seismic survey, areas, the five nearshiore geophone .alignment~s adjacent to DCPp, the onshore s~und s0ources (Vibroseis T M trucks, AWD trucks and sle~dgehammer) and receiver (geophone).routes, and existing paved areas withfin DCPP that.would be used for staginig (Figures 2 and 6- of Attachehnet' 2). No Site .preparation or ground distuirbance

(vegetation removal, grading, etc.) for staging area~s would be required.

Vibrso.seistM and AWD trucks would operate on existinig, :established on the property.

Ground within the..APE woulid nieg.igible, iimited to .the placement of ~geophoees on the grundt surface ad fiv'e anchors (or' clump weights) used secure the, fivie nearshore geophone:

arrays rto. the. ocean, floor. The vertical APE would extend from the;ground surface to .a depth of five inches below the surfaceto accommodate the geophone spikes. Within the nearshore, marine, env~ironment,.

the vertical extendi to a maximum of inistallations or .facilities ae proposed as part f the. Project.Native American outreach for the Diab~lo.

... ................

... .......The enclosed inventory report (Attachment 2)' identifies

'.54 historic~properties: (including 8hipwrecks Sand seven..other unevalua~ted.

resou!rces that are.assumed, eligible to-the Register for p.urposes) within APE. The 'resourceswere identified thirough-a combination of field survey,.,of the onslhore-sites -re contributing elements Ranc'ho: Canada de los Ososy yPecho-y Islay National Register Historic' District (listing 7500.047, eligible undrcr~iterion D),*

The ,inventory report includes an ,assessment of, effects from the proposed project on historic properties (and unevaluated resources).

The analysis considers t~h findings of POSt`-activity archaeological monitoring for a comiparable onshore Project at Diablo qanyon in 2011 which did n~ot result in any impacts to cultural resources.

Based on the: lack of any ground disturbance with the potential to compromise the iintegrity of r'esouirces, thie lack of permanent installations as well as the distance between the identified shipwrecks and nearshore geophones, NSF has determined that the project will result in "!No Adverse Effect" to the individual sites and the historic district within the APE.In closinig, NSF requests your comments, on the appropriateness of the APE for the proposed Undertaking (p~ursuant to §800.4[a][l])

Dear Mr. Donaldson:

Pacific Gas and Electric Company (PG&E) is conducting a License Renewal Feasibility Study to determine if it is feasible to renewal the Diablo Canyon Power Plant operating licenses.

As part of the license renewal process, NRC requires license applicants to "assess whether any historic or archaeological properties will be affected by the proposed project." NRC may also request an informal consultation with your office at a later date under Section 106 of the National Historic Preservation Act of 1966, as amended (16 USC 470), and Federal Advisory Council on Historic Preservation regulations (36 CFR 800). By contacting you early in the application process, we hope to identify any issues that need to be addressed or any information your office may need to expedite the NRC consultation.

The current operating licenses expire in 2024 and 2025 for Units 1 and 2, respectively.

If PG&E decides to pursue license renewal, based on the results of this feasibility study, the operating license would extend for an additional 20 years to 2044 and 2045. The decision to pursue license renewal has not yet been made.Diablo Canyon Power Plant (DCPP) is located within the PG&E owner-controlled area, which consists of approximately 760 acres of land located in San Luis Obispo County, adjacent to the Pacific Ocean and roughly equidistant from San Francisco and Los Angeles. It is located directly southeast of Montana de Oro State Park and is approximately 12 miles southwest of the city of San Luis Obispo, the county seat and the nearest significant population center (Figure 2.1). The DCPP is located on the Port San Luis, Ca 7.5' USGS Quadrangle in the unsectioned area of Canada De Los Osos Y Pecho Y Islay Land Grant in Township 31 South, Range 10 East.Three transmission lines connect the power plant to the regional grid, and are thus relevant to the License Renewal Feasibility Study (Figure 3.1-2). They include: ,, Diablo-Mesa

-One double-circuit line was connected to an existing Morro Bay-Mesa line 10.25 miles from DCPP with an 80-ft. right-of-way width.Diablo Canyon Power Plant Page D-2.License Renewal Application APPENDIX E ENVIRONMENTAL REPORT* Diablo-Gates

-One single-circuit line was connected to the Gates Substation in Fresno County 79 miles northeast of DCPP with a 350-ft. right-of-way width.* Diablo Midway #2 and 3 -Two single-circuit lines were connected to the Midway Substation in Kern County 84 miles southeast of DCPP with a combined right-of-way width of 400 ft.In total, there are approximately 170 miles of corridor that occupy approximately 4,500 acres. The corridors pass primarily through foothills sand rolling land. In addition, there are parcels of land that are agricultural and forest land.PG&E has completed a Technical Report documenting known cultural resources within 6 miles of the DCPP and 2.4 mile corridor around the Transmission Line (Attachment A). In order to compile this information a data search was completed at the California Historical Resources Information System (CHRIS), an internal PG&E data search and using the National Register Information System on-line database.

This report also describes our current Cultural Resources Management Plan for CA-SLO-2, which is located adjacent the DCPP facility.PG&E does not expect continued DCPP operations to adversely affect cultural resources in the APE, as PG&E has no plans to alter current operations or disturb any land for the proposed project. No construction along any of the transmission lines is planned. Maintenance on the transmission lines would continue as currently performed.

If you have any questions or concerns regarding this project please feel free to call me (916) 201-8571.After your review, we would appreciate your input detailing any concerns you may have about cultural resources in the current study area or confirming PG&E's conclusion that operation of DCPP over the license renewal term would have no effect on cultural resources.

This will enable us to meet our application preparation schedule.

PG&E will include a copy of this letter and your response in the Environmental Report that may be submitted to the NRC as part of the DCPP license renewal application.

Thank you for taking the time to review this project.Best Regards, Maggie Trumbly Cultural Resource Specialist Enclosure (Technical Report)Diablo Canyon Power Plant Page D-3 License Renewal Application APPENDIX E ENVIRONMENTAL REPORTAreas l~Environmental Report~Diablo Canyon Power Plant I Figure 2.1-2~50-Mile Vicinity Map Diablo Canyon Power Plant License Renewal Application Page D-4 APPENDIX E ENVIRONMENTAL REPORT SAN BERNARDINO

Dear Ms. Smith:

Thank you for seeking my consultation regarding the above noted undertaking.

Pursuant to 36 CFR Part 800 (as amended 8-05-04) regulations implementing Section 106 of the National Historic Preservation Act (NI--PA), the National Science Foundation (NSF) is seeking my comments on the effects the proposed undertaking will have on historic properties

...The project consists of Pacific Gas and Electric (PG&E) conducting seismic imaging studies in the vicinity of the Diablo Canyon Power Plant, both onshore and offshore.The offshore activities include the of an NSF research vessel. The vessel would place geophones along the ocean floor adjacent to the power plant. Geophones would be secured to the ocean bottom with the use of a clump weight. The research vessel would also tow a series of sound generating air guns and hydrophones along several transects to record seismic reflection data.Onshore activities will include the use of Vibroseis and accelerated weight drop trucks on existing paved, gravel and dirt roads. The Vibroseis and accelerated weight drop trucks will not be used within the boundaries of archaeological sites along the dirt or gravel roads. Geophones will be placed along the seismic sound source corridors and onto the adjacent State Park sand spit.The Area of Potential Effects includes the linear alignments of on shore geophones and seismic transects, as well as the offshore placements of geophones.

The vertical APE for effects from geophone placement extends up to five inches deep onshore and up to one foot deep for offshore geophones.

The vertical APE for vibrational effects from the Vibroseis technology on archaeological sites is currently poorly understood; however, PG&E has previously documented that no visible effects to stratigraphy occur 20 meters away from the Vibroseis implementation point. In addition to your letter received September 19, 2012, and email amendment to the project description received October 24, 2012, you have provided the following documents as evidence of your efforts to identify historic properties in the APE:"* Cultural Resources Inventory for the Central California Coastal Seismic Imaging Project (Savannah Hewes et al., Applied EarthWorks, September 2012) 29 October 2012 NSF_2012_0919_001 Page 2 of 2* Memorandum:

Assessment of Impacts for Geoseismic Operations PG&E Central Coastal California Seismic Imaging Project (Damon Haydu, Applied Earth Works, October 2012)PG&E, on behalf of NSF, has searched their internal cultural resource records, as the APE is almost entirely on PG&E property, in addition to searching the records at the Central Coastal Information Center. As a result of the records search, and previous survey and monitoring work in the past two years, PG&E has identified 39 cultural resources within the onshore APE, and 15 known shipwrecks within the APE for offshore activities.

The precise locations of the 15 identified shipwrecks are unknown, and as such the placement of the sea-floor mounted geophones will be directed by divers, ensuring that the geophones are places on seafloor and not within shipwrecks or other, obvious submerged cultural resources.

PG&E will avoid working within 10 meters of the 28 archaeological sites bisected by unpaved roads. One of the remaining 11 archaeological sites is not within the planned sourcing transect, and as such will be avoided by the undertaking completely.

The ten remaining archaeological sites which are bisected by the highly developed paved road will not likely be affected due to the severe cuts and layers of fill upon which the paved road is constructed.

The roads crossing all sites will still be used for access to further portions of the sourcing transects.

Geophones will be placed within the boundaries of sites by crews accessing sites either by foot, or with vehicles on existing roads. The NSF and PG&E have committed to having qualified archaeological monitors present during onshore geophone placement and during sourcing transects to direct and implement the avoidance scheme described above.Based on the NSF and PG&E's identification efforts and avoidance plan, pursuant to 36 CFR 800.5(c)(1), I concur with the NSF finding of No Adverse Effects to historic properties.

Be advised that under certain circumstances, such as unanticipated discovery or a change in project description, the NSF may have additional future responsibilities for this undertaking under 36 CFR Part 800. Thank you for seeking my comments and considering historic properties as part of your project planning.
