The report was submitted in May 1985 and preliminarily reviewed by the staff. After the summary report has been formally reviewed by the Board, the permittee will be notified of the conclusions and whether or not the Board believes that the permittee should submit a plan to reduce the

3 Class:
III Special Standard (s): None Moditication
Description:
The modification consists of revisions to several special conditions, revision of several monitoring frequencies and elimination of an incorrect state-ment concerning heat rejection rate for Outfall 010.
Special Condition #4 is being revised to allow 6 months rather than 3 months for preparation and sub-mission of the final report. During the 316(a) study several modifications were suggested by the Technical AdvisoryCommittee(TAC)andsubsequentlycarriedout by VEPCO. The TAC agreed to allow VEPC0 an additional 3 months to prepare and analyze the new data.
Special Condition #8 has been revised to indicate that the impingement and entrainment report has been submitted but that the review by the Agency has not been completed.
Since reissuance of this pennit, the wording of the chlorine reopener has been modified. Special Condition
- 11 has been revised to reflect the current disinfection language. The monitoring frequency at Outfalls 001, 002 and 009 have been reduced to 1/ month, to more accurately reflect the method of flow measurement.
These outfalls employ timers and a summation of run time to calculate average flow. The final changes are to Outfall 010. An incorrect statement concerning the calculation of heat rejection was included in the

reissued pemit. This statement has been removed.
The actual method of calculation of the heat rejec-tion rate was submitted to the Agency and approved in 1975 and was not accurately defined by the prev-fous definition. Also, the temperature monitoring requirement for this outfall will be removed for the duration of the 316(a) study and until a recommenda-tion concerning the final limitation is made.
Public Notice:
The pemit modification has received public notice in accordance with Regulation 6 and no response was received.
EPA Comments:
EPA commented that the Board should require suffic-ient information to be able to detemine whether or not the waste heat treatment facility (WHTF) is being properly operated. EPA stated that VEPC0 should be required to continue to monitor and report heat re-jection rate at Dike 3.
Finally, EPA recommended that VEPC0 be required to monitor and report the heat re-jected to and from the WHTF.
The staff believes that the proposed permit and any permit conditions that may result from the 316(a) study will be adequate to determine proper operation i
of the facility.
VEPC0 has never reported the heat rejection rate from Dike 5, so such a requirement would be a new requirement rather than a continuation of an existing monitoring condition. Because the discharge from Dike 3 is submerged, flow measurement is not practical and the calculation of a heat rejec-tion rate would not be feasible. Therefore, the staff proposes to continue the current monitoring program until the 316(a) study recommendations are receivcd.
The pemit will be modified as necessary, following review and adoption of the study results.
The staff's rationale for not adopting EPA's comments has been sent to Jef^ ay Hass at EPA.
1 Corps of Engineers Comments:
The COE failed to comment and/or object to the adequacy i
of this modification.
' Previous Board Action:
There has been no previous Board action directly re-lated to the proposed modification.
Staff Conenents:
The staff has notified all appropriate government agencies of the proposed permit modification and has provided each agency an opportunity to comment in j
accordance with Regulation 6.
There exist no un-resolved objections by EPA.

The modification was discussed with Dr. Richard Collins, Director of the Institute for Environmental Negotiations and copies of the proposed permit pages were provided to the Technical Advisory Comittee (TAC). The TAC had no objections to the modifications.
NPDES Permit Number VA 0052451 was issued on 2 June 1977, expired on 2 June 1982, was administratively continued and subsequently reissued on 19 March 1985.
