Box 56 Lockwood, Ca 93932 Re: Pacific Gas & Electric 230kV Electrical Switchyard Voltage Support Project - Diablo Canyon Power Plant, Avila Beach, CA
Dear Mr. Alger:
PG&E proposes to upgrade the existing 230kV switchyard located at the Diablo Canyon Power Plant (DCPP).
The project includes installation of new electrical devices within the switchyard for providing fast-acting reactive power on the electrical transmission network (MVAR Reactive Support Device and a Static VAR Compensator, thyristor controlled switched capacitor bank, or Synchronous Condenser). To accommodate the new devices, a modest expansion of the footprint of the existing switchyard is required. Refer to Attachment A for a location map and an aerial image of the 230 kV switchyard. A red line on the aerial photograph delineates the potential maximum extent of the new footprint of the switchyard as proposed, The existing 230kV switchyard sits atop approximately 50 feet of artificial modemn fill above Diablo Creek.
There is virtually no potential for cultural resources to occur within the area of potential impact.
The switchyard project area is located within the search radius for two recent records searches (2009 and 2012) conducted at the Central Coast Information Center (CCIC) of the California Historical Resources Information System. Additional research was conducted using the files and literature maintained by PG&E in our confidential Cultural Resources Geospatial Database.
The records searches and literature review indicate that the project area has been thoroughly studied in the past, both before the substation was built (Riddell 19661) as well as after the substation was built (Greenwood 2 1972, 1978; Holson 3 1986 and Hewes et al. 4 2012). No archaeological resources have ever been identified within the current project's area of potential impact and are extremely unlikely given that the project footprint is restricted to artificial fill. The nearest extant archaeological resource is CA-SLO-02, which is located 255 meters (-835 feet) west of the switchyard at its closest point and will not be affected in any way by the implementation of the proposed project.

Box 517 Santa Ynez, CA 93460 Re: Pacific Gas & Electric 230kV Electrical Switchyard Voltage Support Project - Diablo Canyon Power Plant, Avila Beach, CA
Dear Mr. Cohen:
PG&E proposes to upgrade the existing 230kV switchyard located at the Diablo Canyon Power Plant (DCPP).
The project includes installation of new electrical devices within the switchyard for providing fast-acting reactive power on the electrical transmission network (MYAR. Reactive Support Device and a Static VAR Compensator, thyristor controlled switched capacitor bank, or Synchronous Condenser). To accommodate the new devices, a modest expansion of the footprint of the existing switchyard is required. Refer to Attachment A for a location map and an aerial image of the 230 kV switchyard. A red line on the aerial photograph delineates the potential maximum extent of the new footprint of the switchyard as proposed.
The existing 230kV switchyard sits atop approximately 50 feet of artificial modemn fill above Diablo Creek.
There is virtually no potential for cultural resources to occur within the area of potential impact.
The switchyard project area is located within the search radius for two recent records searches (2009 and 2012) conducted at the Central Coast Information Center (CCIC) of the California Historical Resources Information System. Additional research was conducted using the files and literature maintained by PG&E in our confidential Cultural Resources Geospatial Database.
The records searches and literature review indicate that the project area has been thoroughly studied in the past, both before the substation was built (Riddell 19661) as well as after the substation was built (Greenwood 2 1972, 1978; Holson 3 1986 and Hewes et al. 4 2012). No archaeological resources have ever been identified within the current project's area of potential impact and are extremely unlikely given that the project footprint is restricted to artificial fill. The nearest extant archaeological resource is CA-SLO-02, which is located 255 meters (..835 feet) west of the switchyard at its closest point and will not be affected in any way by the implementation of the proposed project.

Dear Mr. Taggart:
A record search of the NAHC Sacred Lands Inventory failed to indicate the presence of Native American traditional cultural places in the Project site(s) or 'area of Potential effect' (APE), submitted to This office. Local tribes consider this area very Scultu~rally sensitive. Note also that the absence of archaeological andfor Native American cultural resources does not preclude their existence at the subsurface level.
In the 1986 Appellate Court decision (170 Cal App 3rd 604). the Court held that the NAHO has jurisdiction and special expertse, as a state agency, over affected Native American resources impacted by proposed projects, including archaeological places of religious significance to Netive Americans, and to Native American burial sites.
Attached is a list of Native American tribes, Native American individuals or organizations that may have knowledge of cultural resources In or near the proposed project area (APE). As part of the consultation process, the NAHC recommends that local government and project developers contact the tribal governments and native American individuals on the list in order to determine If the proposed action might impact any cuilturaI places or sacred sites. If a response from those listed on the attachment is not received In two weeks of notification, the NAHO request that a follow-up telephone call be made to ensure the project information has been received.

Description:
PG&E proposes to upgrade the existing 230kV switchyard located at the Diablo Canyon Power Plant (DCPP). The project includes installation of the installation of +150/-75 MVAR Reactive Support Device and a Static VAR Compensator (SVC), thyristor controlled switched capacitor bank, or Synchronous Condenser. To accommodate this work, expansion of the footprint/boundary of the existing switchyard is required. The entire switchyard, as well as all areas of ground disturbance for the current project are located within an area of very deep artificial fill. The project area has been surveyed in the past for the presence of cultural resources, which are absent. No impacts no Native American cultural resources are anticipated.

Dear Ms. Odom:
PG&E proposes to upgrade the existing 230kV switchyard located at the Diablo Canyon Power Plant (DCPP).
The project includes installation of new electrical devices within the switchyard for providing fast-acting reactive power on the electrical transmission network (MVAR Reactive Support Device and a Static VAR Compensator, thyristor controlled switched capacitor bank, or Synchronous Condenser). To accommodate the new devices, a modest expansion of the footprint of the existing switchyard is required. Refer to Attachment A for a location map and an aerial image of the 230 kV switchyard. A red line on the aerial photograph delineates the potential maximum extent of the new footprint of the switchyard as proposed.
The existing 230kV switchyard sits atop approximately 50 feet of artificial modern fill above Diablo Creek.
There is virtually no potential for cultural resources to occur within the area of potential impact.
The switchyard project area is located within the search radius for two recent records searches (2009 and 2012) conducted at the Central Coast Tnformnation Center (CCIC) of the California Historical Resources Information System. Additional research was conducted using the files and literature maintained by PG&E in our confidential Cultural Resources Geospatial Database.
The records searches and literature review indicate that the project area has been thoroughly studied in the past, both before the substation was built (Riddell 1966') as well as after the substation was built (Greenwood 2 1972, 1978; Holson 3 1986 and Hewes et al. 4 2012). No archaeological resources have ever been identified within the current project's area of potential impact and are extremely unlikely given that the project footprint is restricted to artificial fill. The nearest extant archaeological resource is CA-SLO-02, which is located 255 meters (--835 feet) west of the switchyard at its closest point and will not be affected in any way by the implementation of the proposed project.

RE: PG&E 230kV Switchyard Upgrade Attachments: photo 3.JPG
Dear Mr. Perez,
Thank you very much for the thoughtful response. i appreciate your perspective and we are in regular contact* with Northern Chumash in the San Luis Obispo area (Yak Titu Titu band, Northern Chumash Tribal Council, Odom family, etc.). At this point I have no reason to believe there is the potential to encounter cultural resources within the project site and do not plan to have the work monitored. To give you a sense of the depth of fill that was placed over Diablo Creek during construction of the switchyard I have attached a photograph. Construction for the current project will not come close to the base of the fill as it is extremely deep.
In addition, we do regular training with staff and construction crews to ensure all inadvertent discovery protocols are followed.

Re: PG&E 230kV Switchyard Upgrade Mr.Taggart, I have reviewed the enclosed information and feel that the project should not have anY impacts to Cultural Resources in the area. However, I would like to see more Native involvement for determining what is on the surface of this proposed work area. The need to successfully manage our resources requires that when a Archeologist does a Phase i field survey a qualified Native consultant should be present for these surveys so as to expedite the process of site preservation and to represent the Native Americans interest. I also would like to know if there is going to be a Archeologist present during construction and excavations and if so I feel a Native consultant should be present. I know that they have previously disturbed this area with previous construction, but if they are going deeper than previou~s excavations there could be a potential for impacts to unrecorded or buried sites. Due to the proximity to Ca-SLO-02 there should be a Consultant on site to monitor if buried subsurface deposits are encountered. Thank you for the opportunity to respond and I look forward to hearing from you.

RE: PG&E 230kV Switchyard Upgrade Good morning Mona, Thanks for your response. Regarding the fill, the 230kV switchyard (and the 500kV yard) is built upon an artificial landform that was created by filling a drainage with many feet of fill. Much of the fill likely came from the adjacent hillside next to the plant that was removed during construction. At its deepest point, I believe the fill reaches depths of 50 - 60+ feet.
I wholeheartedly share your concern for the resources nearby, the nearest being SLO-02. As you may be aware, entry into the site boundary of SLO-02 (for purposes other than for security) requires permission from me and the DCPP Site Vice President in compliance with our operating license.
Please let me know if I can provide any further information on this project for you.
- Best, Mike From: Mona Tucker [2]

Thank you for notifying us of the PGE project: PG&E 230kV Switchyard Upgrade. We're always concerned about activities that take place in proximity to the Diablo power plant as that area is a known and immensely important culturally sensitive site for yak tityu tityu yak tilhini - Northern Chumash Tribe.
We have taken note of your comment that due to the use artificial fill there is no possibility of encountering cultural resources. Can you please explain the term "artificial fill"?
Also, we ask you keep a watchful eye to prevent any inadvertent disturbance in nearby culturally sensitive areas.
Best regards, Mona Mona Olivas Tucker, Tribal Chair yak tityu tityu yak tilhini - Northern Chumash Tribe 1

Dear Mona,
I am following up on a letter I recently sent you regarding the above referenced project. As I indicated, PG&E proposes to upgrade the existing 230kV switchyard located at the Diablo Canyon Power Plant (DCPP). The project includes installation of new electrical devices within the switchyard for providing fast-acting reactive power on the electrical transmission network (MVAR Reactive Support Device and a Static VAR Compensator, thyristor controlled switched capacitor bank, or Synchronous Condenser) to enhance safety and reliability of the system. To accommodate the new devices, a modest expansion of the footprint of the existing switchyard is required. I have attached a location map and an aerial image of the 230 kV switchyard. The red line on the aerial photograph delineates the potential maximum extent of the new footprint of the switchyard as proposed.
The existing 230kV switchyard sits atop approximately 50 feet of artificial modemn fill above Diablo Creek. There is virtually no potential for cultural resources to occur within the area of potential impact. No archaeological resources have ever been identified within the current project's area of potential impact and are extremely unlikely given that the project footprint is restricted to artificial fill. The nearest extant archaeological resource is CA-SLO-02, which is located 255 meters ('-835 feet) west of the switchyard at its closest point and will not be affected in any way by the implementation of the proposed project.

Dear Xielolixii:
PG&E proposes to upgrade the existing 230kV switchyard located at the Diablo Canyon Power Plant (DCPP).
The project includes installation of new electrical devices within the switchyard for providing fast-acting reactive power on the electrical transmission network (MVAR Reactive Support Device and a Static VAR Compensator, thyristor controlled switched capacitor bank, or Synchronous Condenser). To accommodate the new devices, a modest expansion of the footprint of the existing switchyard is required. Refer to Attachment A for a location map and an aerial image of the 230 kV switchyard. A red line on the aerial photograph delineates the potential maximum extent of the new footprint of the switchyard as proposed.
The existing 230kV switchyard sits atop approximately 50 feet of artificial modemn fill above Diablo Creek.
There is virtually no potential for cultural resources to occur within the area of potential impact.
The switchyard project area is located within the search radius for two recent records searches (2009 and 2012) conducted at the Central Coast Information Center (CCIC) of the California Historical Resources Information System. Additional research was conducted using the files and literature maintained by PG&E in our' confidential Cultural Resources Geospatial Database.
The records searches and literature review indicate that the project area has been thoroughly studied in the past, both before the substation was built (Riddell 1966') as well as after the substation was built (Greenwood 2 1972, 1978; Holson 3 1986 and Hewes et al.4 2012). No archaeological resources have ever been identified within the current project's area of potential impact and are extremely unlikely given that the project footprint is restricted to artificial fill. The nearest extant archaeological resource is CA-SLO-02, which is located 255 meters (~-835 feet) west of the switchyard at its closest point and will not be affected in any way by the implementation of the proposed project.
