-3 Human Health HP-1. Issue:
The applicant's evaluation identified five locations where the transmission lines exceeded the National Electrical Safety Code (NESC) recommended standard of 5 milliamperes for electric shock concern. However, the environmental report (ER) does not contain a discussion of any mitigation measures being considered for the locations where the electric shock potential exceeds the NESC standard.
Background:
As required by Title 10 of the Code of Federal Regulations (10 CFR) 51.53(c)(3)(ii)(H),
Section 4.13 of the STP ER contains an evaluation of the acute shock potential from the transmission lines within the scope of license renewal. The applicant's evaluation identified five locations where the transmission lines exceeded the NESC recommended standard of 5 milliamperes. For these transmission lines, the applicant's ER concluded
"... that electric shock is of MODERATE significance, because 1) there are few exceedances of the NESC standard, 2) the exceedances are a small percentage of the standard, 3) the locations of the exceedances are very remote or on private property, and 4) the transmission service providers have not received any complaints about induced-current shock. Accordingly, no mitigation measures are required." Hence, the ER does not contain a discussion of any mitigation measures being considered for the locations where the electric shock potential exceeds the NESC standard.
10 CFR 51.53(c)(3}(iii) states that the ER " ... must contain a consideration of alternatives for reducing adverse impacts, as required by 10 CFR 51.45(c), for all Category 2 license renewal issues ... " 10 CFR 51.45(c) states, "The environmental report must include an analysis that considers and balances the environmental effects of the proposed action, the environmental impacts of alternatives to the proposed action, and alternatives available for reducing or avoiding adverse environmental effects."
Requested Information:
Please provide additional information related to alternatives available for reducing or avoiding adverse environmental effects from those transmission lines that exceed the NESC standard.

Clarification request:
WR-17.
Background:
Based on the document review and site audit, the staff understands that the #24 event has led to the highest level of tritium sampled in the protected area piezometer network. In accordance with (a) 10 CFR 51, Subpart A, Appendix B, Table B-1 and (b) Environmental Standard Review Plan (ESRP), NUREG-1555, Supplement 1, Sections 2.2.3 and 4.5, the staff requests source event documentation that contains relevant information for the review (e.g., cause, timing, volume, concentrations, etc.),
to assess what is typically known of TDS line failures and releases to the environment and possible impact on the groundwater quality.
Requested information:
For clarification purposes, the staff requests additional information related to releases to the subsurface that have occurred within the protected area as a result of TDS line failures, as noted in Section 2.3.4 of the ER and discussed in the MACTEC report (MACTEC, May 20,2009). The staff requests the applicable STP Condition Reports (CRs), for the #24 event shown in Table 6-1 and Figure 6-1 in the MACTEC report, be made available for review. The following related CRs are also requested for the review: CR 03 7595, CR 03-3951, and Activity No. 430966.
- 6 WR-18.
Background:
During the site audit tour of the protected area, the release of tritiated water to the ground surface and ultimately to groundwater from the Auxiliary Steam and Condensate Storage and Transfer Piping systems at each of the units was observed by the staff and described by the applicant. These discharges are also described briefly in the MACTEC report and mentioned in Section 2.3.4 of the ER. In accordance with (a) 10 CFR 51, Subpart A, Appendix B, Table B-1 and (b) ESRP, NUREG-1555, Supplement 1, Sections 2.2.3 and 4.5, the staff requests documentation to complete its review of groundwater quality degradation beneath the protected area.
Requested information:
For clarification purposes, the staff requests the proposal or planning documentation or both, including documentation of the existing steam condensate quantity and quality, related to the proposed engineering change to the "Auxiliary Steam and Condensate Storage and Transfer Piping" to eliminate the discharge of tritium directly to the ground surface. Further, please clarify and provide supporting documentation on the interception of these releases by (a) the sump(s) within the tendon gallery of each reactor containment building and (b) the sump water release point(s).
WR-19.
Background:
Section 4.5 of ER provides an estimated drawdown for the initial40-year period. The staff requests that the drawdown analysis be extended to encompass continued operation of production wells through the end of the proposed license renewal period. In accordance with (a)10 CFR 51, Subpart A, Appendix B, Table B-1 and (b)
ESRP, NUREG-1555, Supplement 1, Sections 2.2.2, 4.5, and 4.5.1, the staff requests this analysis for characterization of the potential impact of license renewal on off-site groundwater production wells located in the Deep Chicot Aquifer.
Requested information:
The staff requests the completion and submittal of an analysis of Deep Chicot Aquifer drawdown due to continued use of the STP production wells (including supporting calculations) by the applicant, for the original license period of 40 years plus the proposed license renewal period of 20 years.
WR-20. The staff requests (a) the correspondence concerning TCEQ's acknowledgement of STP's National Pollutant Discharge Elimination System permit renewal application acceptance and timely submittal and (b) progress towards completion of the new permit.
