Jud Uf, Whiteo Ph.D.Environmental Policy ManagerDominion

Experience: Dr. White has been ernployed by Dominion since 1975 and he has served in variouspositions in the environmental department. These positions have included activity ranging from

environmental field sampling, to regulatorylpermit compliance, to public affairs, to legislativesupport, and to policy development. Currently, Jud oversees water policy issues at all Dominionfacilities in 8 states. He has broad knowledge of state and federal environrnental laws andregulations and has participated on many state/federal advisory groups in helping developenvironmental policy or address an environmental issue. He is also currently an atfiliate professor

at VCU and is teaching a graduate course titled Business and the Environment.

Education - B.S. and M.S. in Biology - Universiry of RichmondPh.D. degree (2000) in hrblic Pclicy and Administration - Virginia Comrnonwealth University(Dissertation Title: Accountability Issues For A PointNonpoint Source Effluent Trading Programin Virginia)

John D. Waddill, P.E.Lead Civi/Mechanical Engineer for the North Anna Combined Operatin$License Project.DominionExperience: Mr. Waddill has been involved in the design and analysis of nuclear power station

systems for 29 years. His areas of concentration have been cooling water systems and thermal and

hydrautic modeling. He led a project team in the development and demonstration of an on-lineheat transfer monitoring system for an operating nuclear station. In 2005, Mr. Waddill joined

Dominion's North Anna Early Site Perrnit and Combined Operating License Project as Lead

CivililVlechanical Engineer and has been the technical lead for the development of the hybridcooling system concept for the proposed Unit 3.

Education: Mr. Waddill holds a Bachelor of Science in Mechanical Engineering fiom VirginiaTech and a Masters of Business Administration from Queens University in Charlotte. He is a

Registered Professional Engineer in Norlh Carolina.

Overview of Nuclear Project

. NRC licensing process: Early Site Permit {ESP) for

site suitabil ity; separate Construction and

Operating License (COL)

. ESP application submitted to NRC in 2003 for 2

units at 1520 MWe each

. In 2003-2006: NEPA process commenced andrequired state concurrence with coastal zoneprogram of state (received in 2006)

. Unit 3 cooling system changed in 2005 from open to

closed cycle due to agency and public concerns

. FEIS issued in 2006; COL application in late 2007;

construction in 2010

State Requirements - CZMA

' State concurrence with our Federal Consistency

Certification under the Coastal Zone Management

Act (CZMA) was needed prior to issuance of E$P

' CZMA was only state authorization needed for

ESP; additional permitting underway in COLprocess

'' CZMA Question asked - ls the proiect consistent

with enforceable policies of the Va. Coastal

Resources Management Program?' Multiple state agencies review as well as public

' State may deny, approve, or approve the

certif ication with conditions

What is an lFlM StudY?

' A widely used tool for assessing the effects of

flow regulation on river habitats for fish; can also

include recreational uses.' Traditional instream flow regulatory

determinations often geared to maximize habitat

. for single life stage of a high-profile fish species

at a few isolated sPots in a river'

' Current lFlM process allows for more

comprehensive regulatory determinations with

consideration for muttipte target species'

' Expect completion in earlY 2008

I4ret/Dry Cooling Concept/How does ityuork?

Closed cycle cooling sysiem design." Ory and water-conserving Wet Cooling Towers. Significantly reduces water consumplbn",. Unit 3's condenser water cooled initially in Dry Towere

(forced air a no water loss), Water then passed throughTowers (water spray 3 some evaporation withreturn).

Two conceptual operating modesEnergy Conservation (EC) - Dry cooling will be reducedreliance mostly on w€t towers for heat removal.Maximum llllater Gonservation (MltVC) - Minimum 1/3removal by Dry, balance of heat removal by t/V€t.

Summary and Lessons Learned' More electricity will be needed in the future and

nuclear energy will play a vital role' New NRC licensing process allows

environrnental review before large investmentsoccur

' While NRC is lead agency, the State has animportant role to play in decision-making

' Ensure effective and continual communicationsbetween NRC, State, and applicant

' Sate CZMA certification process allows multiplestate agencies to voice concerns about a projectand it can significantly influence the outcome
