By letter dated February 6, 2017, the NRC provided Dominion an opportunity to supplement the proposed alternative request identified above by providing: 1) specific analyses or technical evaluations demonstrating the structural integrity of the separate CFRP pipe repairs, and 2) the justification and rationale for the use of the Load and Resistance Factor Design methodology for safety related ASME Class 3 piping, and a discussion of the analysis method used in the original design for Class 3 CW and SW piping, and any variances from applying both methods. Dominion's response to the NRC's request for supplemental information is provided in Attachment 1. The supplemental technical information provided in Attachment 1 for the proposed alternative request was prepared by Simpson Gumpertz & Heger, Inc., and contains information proprietary to that company. Therefore, this information is supported by an affidavit, signed by Simpson Gumpertz-& Heger, Inc., the owner of the information. The affidavit sets forth the bases on_ which the information may be withheld from public disclosure by the Commission and addresses with specificity the considerations listed in paragraph (b)(4) of 10 CFR 2.390 of the Commission's regulations. Accordingly, it is respectfully requested that the information, which is proprietary to Simpson Gumpertz & Heger, Inc., be withheld from public disclosure in accordance with 10 CFR 2.390 of the Commission's regulations.

JIS2313 vi SIMPSON GUMPERTZ & HEGERINC. 10 CFR 2.390 AFFIDAVIT OF RASKO P. OJDROVIC AFFIDAVIT I, Rasko P. Ojdrovic, hereby state as follows: {l) I am the Vice President and Senior Principal of Simpson Gumpertz & Heger Inc. {SGH), and I have been authorized to execute this affidavit on behalf of SGH. (2) Virginia Electric and Power Company will submit a transmittal to the US NRC entitled "Supplement to Proposed Alternative to ASME Section XI Requirements for Repair/Replacement of Buried Chculatingand Service Water Class 3 Piping with Carbon Fiber Reinforced Polymer" Docket Nos. and 50-281, Serial No.17-060. Certain portions of that transmittal contain proprietary information owned by SGH. This information should be held in confidence by the NRC arid withheld from public disclosure. The following is a list of the SOH proprietary information in Virginia Electric and Power Company's transmittal that SGH requests be withheld:

• Attachment 1, Supplemental Response, Alternative Request to Use Carbon Fiber Reinforced Polymer System for the Repair of Buried Circulating and Service Water Piping (3) In making this application for withholding of proprietary information of which it .is the owner, SGH believes that the information qualifies for withholding under the exemption from disclosure set forth in .the Freedom oflnforniation Act ("FOIA"), 5 U.S.C. Section 552(b)(4), the Trade Secrets Act, 18 U.S.C. Section 1905, and NRC regulations 10 CFR 9. 17(a)(4) and 2.390(a)(4) for trade secrets and commercial information be.cause: 1. This information is and has been held in confidence by SGH. ii. This information is of a type that is customarily held in confidence by SGH, and there is a rational basis for doing so because the information includes proprietary information that was developed and compiled by SGH at a significant cost to SGH. This information is classified as proprietary because it contains information relevant to analytical approaches and methodologies not available elsewhere. m. The. information is being transmitted to the NRC voluntarily and in confidence. iv. This information is not available in public sources and couid not be gathered readily from other publicly available information. v. A substantial effort has been expended by SGH to develop and evaluate this information. Public release ofthis information could lead to additional significant cost to SGH and is likely to cause substantial harm to SGH's competitive position and foreclose or redu.ce the ayailability of profit-making opportunities. The value of this information to SGH would be lost or devalued if the information wete disclosed to the public. Affidavit Page 1 \\\DC* OJS 120/000001

• 3152313 vi vi. Public disclosure of the information sought to be withheld would provide other parties, including competitors, with valuable information. SGH's competitive advantage would be lostif its competitors are able to use the results of SOI-I's activities to aid their own commercial activities. For example, SGH's competitive advantage would be lost if its competitors are able to use the results of SGH' s analyses to normalize or verify their own process or if they are able to claim an equivalent understanding by demonstrating that they can arrive at the same or similar conclusions. Making such information available to competitors without their having been required to undertake a similar expenditure of resources would unfairly provide competitors with a windfall, and deprive SGH of the opportunity to exercise its competitive advantage to seek an adequate return on its large investment. vii. The commercial value of the information extends beyond the original development cost, and includes development of the expertise to determine and apply the appropriate evaluation process to the information. The research, development, engineering, and analytical costs thatwent into generating this . information comprise a substantial investment of time and money by SGH. The precise value of this information is difficult to quantify, but clearly is substantial. I declare under penalty of perjury under the laws of the United States of America that the foregoing is true and correct. Executed on 17, 2017. Rasko P.
