8. Supplemen S nt to the Environme E ental Repoort 8.1. Inntroductionn In accorrdance with h the requirements off 10 CFR 500.82 (a)(9)(iii)(A) and tthe guidancce of Regulato ory Guide 1.179, Standa ard Format and Conteents for License Terminnation Planns for Nuclear Power Reacctors (1), th his chapter provides p a ssupplement to the enviironmental rreport describinng any new information n or significcant environm mental channge associatted with the site-specific decommissio d oning and siite closure activities a perrformed at tthe La Crossse Boiling W Water Reactor (LACBWR)

( site.

8.1.1. Purpose P

This chaapter supplem ments the 1972 1 Dairylaand Power Cooperativee (Dairylandd) Environm mental Report, LaL Crosse Boiling B Waterr Reactor (EER) (2), whiich was revised on June 15, 1973 (33), by describinng any new information n or significaant environm mental channges associatted with thee site-specific decommisssioning and d license termination t activities presented iin this Liccense Terminattion Plan (LLTP). This supplement,, including rreference too LTP Chappter 3, provides a detailed description d of o the remaining decomm missioning aand site clossure activitiees, the interaaction between those activ vities and th he environm ment, and thee likely envvironmental impact of those activitiess.

The supp plement disccusses wheth her the activ vities and thheir impacts are bounded by the im mpacts predictedd by the Un nited States Nuclear Reegulatory Coommission ((NRC) NUR REG-0191, F Final Environm mental Stateement related d to operatiion of La CCross Boilingg Water Reaactor, April 1980 (NUREG G-0191) (4); NUREG-05 586, Supplement 1, Geeneric Envirronmental IImpact Stateement (GEIS) on o Decomm missioning off Nuclear Facilities, F NNovember 22002 (5); annd the Dairyyland LACBWR R Decommisssioning Pla an and Postt-Shutdown Decommissiioning Activvities Reporrt (D-Plan/PSD DAR) (6). This T chapter discusses deecommissionning activitiies, with a foocus on activvities to be peerformed fro om time of submittal of this LTP until the coompletion of site restorration activitiess.

8.1.2. Background B

LACBW WR consists of a single Allis-Chalm mers designeed 50 megaw watt electricc (MWe) Booiling Water Reactor (BWR R) constructted in 1967 as a demonnstration reaactor in conjjunction witth the U.S. Ato omic Energy Commissio on (AEC). TheT plant waas commissiioned in Novvember 19699. In 1973, thee reactor andd its fuel weere transferreed to Dairylland. It wass operated byy Dairylandd until April 30,, 1987, when n it was shuut down because of econnomic reasoons due to itts small sizee and electricall output. The T plant was w placed in i SAFSTO OR on Auguust 7, 1991. An initiall Site Characterization Surv vey for SAF FSTOR was completed c inn October 19995.

Limited dismantlem ment activitiees were staarted in 19994, includinng the remooval and offf-site disposal of the Reacctor Pressurre Vessel (R RPV) in Maay 2007. All of the sppent nuclear fuel, consistinng of 333 sppent fuel asssemblies, waas transferreed from the Fuel Elemeent Storage Well (FESW) to dry cask storage at th he on-site Inddependent S pent Fuel Sttorage Installlation (ISFS SI) by September 19, 2012. On March h 12, 2014, Dairyland D suubmitted a revision of thhe LACBW WR D-8-1

La Crossse Boiling Water W Reactorr License Termination T Plan Revisionn0 Plan/PSD DAR to the NRC N that acccounts for the t completiion of the sppent fuel trannsfer. Addittional characterrization wass performed d by Energ gySolutions commencinng on Octoober 9, 20144 and concludin ng on Augu ust 6, 2015. The resultss of the sitee characterizzation surveeys performeed by EnergySo olutions is documented d in i two separrate reports, L LACBWR Radiological Characterizzation Survey Report R for October O andd November 2014 Fieldd Work (7) and LACBW WR Radioloogical Characteerization Surrvey Report for f June thru u August 20115 Field Woork (8).

As stated d in the D-Pllan/PSDAR,, Review off post-operat ating license stage enviroonmental im mpacts was docu umented in a supplemen nt to the Ennvironmentall Report forr LACBWR dated Deceember 1987. LA ACBWR deecommission ning and dism mantlement activities haave resulted in no signifficant environmmental impact not prev viously evalu uated in thee NRC's Ennvironmentaal Assessmeent in support ofo the Augusst 7, 1991, Decommissio D oning Order or NUREG G-0191 relateed to operatiion of LACBW WR, dated Ap pril 21, 1980 0. This review includedd the evaluaation of impaacts against those noted in the ER and d NUREG-0 0586. The reference B BWR facilitty in NURE EG-0586 waas the 1,155 MW We WNP-2 BWR operrated by Waashington Puublic Powerr Supply Syystem (plantt now known as a Columbiaa Generatin ng Station, owned and operated bby Energy N Northwest). As LACBW WR is a much h smaller reaactor comparred to WNP--2, its impaccts fall withinn the enveloope of the geneeric environm mental asseessment. NUREG-0586 N 6 also provvided inform mation abouut the decommiissioning im mpact of a sm mall 58.2 meegawatt therrmal (MWt) BWR demoonstration reeactor located in Elk Riverr, Minnesotaa, which wass dismantledd between 1971 and 19774. It was nnoted that this decommissiioning was completed c saafely with liittle risk to w workers andd the public. The Elk Riveer facility waas another Allis-Chalme A ers reactor, a superheated test BWR R, which achieved license teermination in n 1974 (9).

The latesst D-Plan/PS SDAR docum ment (issued in March 20014) concludded the folloowing:

The environmentall impact off all compleeted or plannned LACB BWR decom mmissioningg and dismantleement activiities is SMA ALL as determ mined by thhe GEIS. LA ACBWR deccommissioniing is specificaally evaluated in the GEIS. As stateed in the GE EIS, licenseees can rely oon informatiion in this Supp plement as a basis for meeting m the reequirementss in 10 CFR 50.83(a)(6)((ii). Site-speecific potential environmen ntal impacts not determin ned in the G GEIS are:

Site Location n and Descrription LACBW WR is located d in southw western Wiscconsin, in V Vernon Counnty, on the eeast shore oof the Mississip ppi River, ab bout 1 mile south of thee Village off Genoa, WI and approxximately 19 m miles south of the city of La L Crosse, WI. W The Sitte Regional Location graphic (Figurre 8-1) show ws the site locattion, includinng nearby prominent feaatures such as highwayss, rivers andd lakes. Thee map coordinattes for LAC CBWR are longitude l 91o, 13, 53.335 West aand latitude 43o, 33, 36.22 8-2

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 North. The T site is ata mile 678.6 6 on the Mississippi Rivver above thhe mouth off the Ohio R River.

The Reacctor Building g is approximately 300 feet from thhe Mississipppi River andd 475 feet weest of the cargo o-carrying-onnly rail roadd. The Reacctor Buildingg stands on filled land aat an elevation of 639 feet Above Meean Sea Lev vel (AMSL L), or 19 fe et above thhe normal elevation of the Mississip T covered land consistted of the rivver edge andd low forest aareas which were ppi River. The filled witth sand mateerial dredged d from the Mississippi M R River.

The licen nsed site com mprises a total of 163.5 acres whichh is owned bby Dairylandd, with the aactual LACBW WR plant com mprising only y 1.5 acres. The site is accessed byy a road on the south siide of the plant off of Highw way 35. Oth her prominen nt site featurres include:

the laand north off the LACBW WR plant, which w includes the site switchyard aand the site oof the formeer Genoa No o. 1 Station (G-1)

( coal (aand later oil)) fueled pow wer plant (remmoved in 1989),

the laand area dirrectly south of LACBW WR, which ccontains an operational 350 MWe fossil generrating stationn (Genoa No.

N 3 Fossil Station S [G-33]), located approximateely 175 feet from the LACBWR L plant, the laand area soutth of G-3, where w the ISFFSI is locatedd, and the paarcel of land d to the east of o Highway 35, across fr from LACBW WR.

The Site Overview (F Figure 8-2) illustrates i the boundary oof the licenssed site.

The site is i bordered on o the north h by the Misssissippi Riveer and a narrrow strip of land betweeen the Mississip ppi River annd Highway 35. The U..S. Lock & Dam No. 8, managed bby the U.S. A Army Corps off Engineers (USACE)

( Ro ock Island District, D is loocated approximately 0.66 miles upstrream.

The site is bordereed on the west w by thee Mississipppi River annd bordered on the easst by Highway y 35. A Burlington B Northern-Sa N anta Fe raill line, locaated betweeen the site and Highway y 35, carries commerciall freight alo ong the easteern portion oof the site. Passenger ttrains currentlyy do not use this rail line. The site is bordered to the southh by a segm ment of the UUpper Mississip ppi River Naational Wild dlife & Fish h Refuge Poool 9 area. F Further soutth, approxim mately 2.4 miless from LAC CBWR, is the t Genoa National Fiish Hatcheryy, which raaises endanggered mussels, brook trou ut and sturgeon. On th he southwesstern cornerr of the sitee, approxim mately 0.75 milees south of th he LACBWR R plant, therre is a publicc boat launchhing ramp wwith a parkingg lot.

8.2.1. Site Descripttion After Unrestricted U d Release This secction provid des a summ mary of the final conddition of thee site at thhe conclusioon of decommiissioning and d site closurre activities. The End-S State for LAACBWR deccommissioniing is defined as a the configguration of the t remainin ng below groound backfillled buildinggs, structures and piping an nd open lan nd areas at the time of license teermination m meeting the requiremennts of 10 CFR 20.1402.

2 The deco ommissionin ng of the Claass 1 areas of o the plant (the on-sitee radiologicaally contaminnated buildingss, structures and compo onents) will include the demolition, removal annd disposal oof all structures above a deepth of 3 feeet below grad de (designat ed as 636 fooot AMSL). All systemss will be remov ved from baasements loccated below the 636 fooot elevation leaving onlly concrete walls and floo ors in the End-State.

This app proach will apply to thhe followinng buildingss and structures:

8-3

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 Reacttor Building g, Wastte Treatmentt Building, Ventiilation Stackk, Pipe and Ventilattion Tunnelss, Wastte Gas Tank Vault, Turbiine Building g and Turbin ne Office Buiilding, Low Specific Acttivity (LSA)) Storage Bu uilding, and Mainntenance Eat Shack.

The debrris generated d from demolition and reemoval operaations will bbe segregatedd for recycliing or disposal.

Figure 8--3 shows th he key LAC CBWR build dings at the site. All oon-site LAC CBWR builddings, structures and compo onents, otheer than the LACBWR L A Administratioon Building and Crib H House, will be demolished d and a removed d to a depth of o at least 3 feet below ggrade. Nonee of the buildings and strucctures assocciated with G-3 G are exp pected to bee radiologicaally impacteed such thatt they require reemedial actiions; therefo ore, no remed diation is plaanned and thhese structurres, includinng the G-3 Crib b House, willl remain intaact and funcctional for G G-3 power opperations. A Any contaminnated structures at depths greater g than 3 foot below w grade willl be assessedd for radioloogical impacct and potential removal. Further F inforrmation on the t approachh to the variious buildinngs is providded in the LTP Chapter 3.

The belo ow grade stru uctures to reemain in thee End Statee such as bbasement fouundations w will be filled witth suitable clean c soil, saand and/or other o suitablle media, ass allowable under Wisconsin Department of Naturral Resourcees (WDNR) regulations . The restoored areas onn the site w will be backfilled, returned to t grade, seeeded and app propriate ero sion controls will be established.

The stru uctures outside of the LACBWR R Site Encllosure (LSE) are not expected tto be dismantleed and will remain r on site. These innclude:

Administration Building, B inclluding assocciated sanitarry sewer andd water systeems and pipiing, LACB BWR Crib House, H inclu uding fire prootection pipiing systems, Outfaall diffuser discharge d pip ping, extendiing 110 feet into the Misssissippi Rivver, G-3 Coal C Plant an nd all associiated buildin ngs, warehouuses and suppport structurres, includinng the coal barge washiing station to t the northh of the plannt and all asssociated saanitary sewerr and waterr systems an nd piping, Electtrical Switchhyard, and, Paved d roadways and the Burrlington Norrthern-Santa Fe rail line and spur innto the LACB BWR plant area.

After all demolition and remediiation activiities are com mplete, a Fiinal Radiatioon Survey ((FRS) process asa described in Chapter 5 of this LT TP, will be pperformed too demonstratte that LACB BWR and the surrounding s open land areas within n its license d boundariees, with the exception oof the 8-4

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 ISFSI faacility, com mply with the radiolo ogical criterria for unrrestricted uuse specifieed in 10 CFR 20.1402.

2 Ass part of the decommissiioning proceess, all spentt nuclear fueel was loadedd into dry storaage casks and transferred d to the ISFSI. It is exppected that tthis spent fuuel will remaain in dry storage within the ISFSI untiil it is transfeerred to the D Department of Energy (D DOE).

Isolation and contro ol measures will be imp plemented fo following the conclusionn of radioloogical remediation activities. These acttivities will be completeed prior to sttarting the F FRS process. The control measures m will w be impllemented to o ensure thee final radiiological coonditions aree not comprom mised by th he potential for re-con ntamination as result of access bby personneel or equipmen nt. Open laand areas, acccess roads and a boundarries will be posted withh signs restriicting access. Isolation I andd control meeasures will remain in e ffect throughhout FRS acctivities andd until there is no n risk of re-contamination from decommissionning. These measures arre not requirred in survey arreas that hav ve been releaased from thee license.

Several services s such h as sanitaryy sewer serviices and elecctrical servicce will remain in operatiion to support thet ISFSI monitoring m and a security operations. There aree three potabble wells onn site supportin ng the adjaceent G-3 fossiil station whhich will remmain in placee.

8.3. Remaining R Dismantlem D ent and Deccommission ning Activitiies To date, several key dismantlem ment and deco ommissioninng activities have occurrred, includinng the removal of the follow wing compon nents:

RPV and associaated reactor componentss (e.g. fuel shrouds, control rods, ssteam separaators, incorre monitor gu uide tubes, etc.),

e FESW W stored com mponents su uch as fuel shhrouds, contrrol rods, andd start-up souurces, and Varioous system piping p and components c associated with the Foorced Circulaation system m, the RPV,, and primarry systems su uch as the Control Rod D Drive Mechaanisms, Deccay Heat, Priimary Puriffication, Seall Injection annd Main Steam.

Varioous Turbine and auxiliarry systems.

Chapter 3 of this LTP provides detailed d desccriptions of the dismantlement, decoontaminationn and remediation activitiees currently being b perforrmed and thhe remainingg activities tto be executted to achieve the t End-Staate conditio on.

8.4. Immpacts to thhe Post-Shu utdown Deco ommissionin ng Activitiees Report (PPSDAR)

As previiously noted d, the D-Pllan/PSDAR, amended in March 2014, describbed the plaanned decommiissioning op perations at the t site and concluded tthat the poteential enviroonmental im mpacts associateed with deco ommissionin ng the site haave already been postulaated in, andd will be bouunded by the prreviously issu ued environm mental impaact statementts, specificallly:

NURREG-0191, an nd NURREG-0586.

Chapter 3 of the LT TP identifiees the dism mantlement aand decontaamination acctivities thaat are scheduled to be com mpleted prio or to the un nrestricted reelease of thhe site (exclluding the IISFSI footprint). The identtified activitiies are not significantly different froom those oriiginally discuussed 8-5

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 in the D--Plan/PSDAR. Althoug gh additionall details regaarding major decommissioning activvities will be defined d durinng decommiissioning planning efforrts, no signiificant impacts beyond those identifiedd in the D--Plan/PSDAR R have beeen identifiedd. Subsequuent sectionss in this chhapter provide additional evaluation and inforrmation reggarding the environmeental effectts of decommiissioning.

8.5. La L Crosse Bo oiling Wateer Reactor Environmen E nt Descriptioon 8.5.1. Geography G and a Demogrraphy 8.5.1.1. Site Location L and Descriptionn The site location and d description n were discuussed in sectiion 8.2. Thee 163.5 acree site is locatted in Vernon County, C Wissconsin, in the t Mississip ppi River Valley, with tthe Reactor Building loocated 300 feet from the easst bank of thee Mississipp pi River. Tw wenty-seven acres of the site were foormed by fillingg in river eddge and low forest areass with materrial dredgedd from the M Mississippi R River.

The site is relatively y flat with th he reactor facilities f stannding at elevvations rangging from 636 to 642 feet AMSL bou unded by thee railroad tracks to the east and thhe riprap on the shore oof the Mississip ppi River to the west. The T geology y consists prrimarily of ffill materialss (fine sands and silts) undderlain by finne to medium m sands with h some soilss containing higher percentages of ccoarse sands and d gravels. Bedrock B is en ncountered at a approximaately 130 feeet below grouund surface (10).

8.5.1.2. Popullation The U.S. Census Bu ureau, Amerrican Comm munity Surveey (ACS) reeport (11) prrovides the most reliable census c data for f nearby Wisconsin W viillages and ccities and Veernon Countyy. The estim mated total pop pulation in 2013 2 was 258 for the Viillage of Geenoa, locatedd 1 mile norrth of LACB BWR; 744 for Stoddard, S loccated 7 miless N of the pllant; 51,522 for La Crosse, the largest Wisconsinn city near the plant, locatted 17 miles N; and 30,,329 for Verrnon Countyy. There arre also numerous small tow wns west of o the plant across the Mississippii River, including Renoo township, MN (populatiion 397), located 3 miles northwest, and New w Albin, IA A (populatiion 513), loocated 5 miles southwest.

8.5.1.3. Site Access, A Land d and Water Use The LAC CBWR propeerty is locateed in the farr western porrtion of Verrnon Countyy on the east bank of the Mississippi M River.

R Altho ough the sitee area is 1633.5 acres, it is relativelyy isolated ass it is bounded by the Misssissippi Riv ver to the west, w a rail liine to the eeast, USACE E property tto the north, annd a wildlife and fish reffuge to the south.

s The ssite includess G-3, a coaal-fired 379 MMWe electric power p stationn completed d in 1969, which w is also owned andd operated byy Dairyland (12).

This stattion is locateed to the so outh, adjacen nt to the LA ACBWR faccilities. Thee closest tow wn is Genoa, lo ocated approoximately 1 mile m to the northeast n of tthe site.

8.5.2. Climate C

The climmate at the La L Crosse region r of Wisconsin W annd at the LA ACBWR sitte is typical of a continenttal climate with w cold wiinters and ho ot summers and extrem mes influenceed because oof the river vallley location of the site. The USAC CE maintainss an active w weather station at the neearby Lock and d Dam No. 8 site with archived a weaather informmation for thee Genoa, WI area. A reeview of the innformation for f the past year (May 2014 to Maay 2015) inddicated tempperatures rannging from 60 to 90o F du uring the mo onths of Jun ne through A August 20144 and 45 to -5o F durinng the winter months m of Deecember 201 14 to Februaary 2015. C City data com mpiled for GGenoa showss that the averaage temperature is approximately 20 2 F in the winter monnths and reacches 72o F iin the o

summer season s (15).

The averrage annual rainfall r is 35 5.2 inches. Monthly M preccipitation avverages in thee Genoa, WII area range froom 3 to 5 incches per mon nth in the sp pring and sum mmer seasonns and from 1 to 3 inchees per month fo or the remainnder of the year.

The blufffs of the Misssissippi Rivver Valley ch hannel the wwinds at the L LACBWR site. Predom minant winds att the site wh here the valley runs no orth-south aare from thee north and the south. The monthly average wiind speeds are typically 6 to 10 m mph. The Genoa, WII area has rrarely experiencced tornadoss. On Aprill 30, 1954, a category F44 (maximum m wind speeds 207-260 mph) tornado occurred o 27.4 miles awaay from the Genoa villaage center. On June 5, 1980, a cateegory F3 (maxiimum wind speeds 158-216 mph) to ornado that ooccurred 6.66 miles awayy from the viillage center injjured one peerson and cau used betweeen $500,000 and $5,000,000 in damaages.

8.5.3. Topography T , Geology an nd Seismolo ogy 8.5.3.1. Topog graphy The site is i located within the Mississippi Riv ver Valley, wwhere the vaalley is deeply cut into hhighly dissectedd uplands. From F La Crosse to Prairie du Chien, approximateely 40 miless south, the vvalley varies beetween 21/2 anda 41/2 miles in width. The valley walls rise ssharply 500 to 600 feet from river leveel. The LAC CBWR site is i located beetween two vvalleys on eeither side off the bluff eaast of Highway y 35. Figure 8-4 providees a Topograaphy Map off the site.

Prior to construction c n of the LAC CBWR facillity, the site location coonsisted of m marshes and low-lying wetlands. Thee property grrade was theen increasedd through thee depositionn of hydrauliically dredged sands from the t Mississip ppi River. During D gradee manipulatiion and site preparation prior to constrruction, the area a was graaded to a rellatively flat ground surfface. The reesulting gradde for 8-7

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 the LACBWR site iss generally flat f with graade level at approximateely 639 feet AMSL from m the access rooad along thee eastern bou undary of thee site to the rriprap alongg the river shhore.

8.5.3.2. Geoloogy LACBW WR is located d on the east bank of the Mississippii River in thee Wisconsinn Driftless seection of the Ceentral Lowlaand Physiogrraphic Proviince (16). T The site is loocated on thee southwest flank of the Wisconsin W Dome and the western flan nk of the Wiisconsin Arcch. The sediimentary straata or bedrock in i this regionn dips less thhan 20 feet per p mile to thhe southwesst.

Generally y, the local geology g is described d as approximate a ely 15 feet of hydraulic ffill overlyingg 100 to 130 feet of glacial outwash and fluvial dep posits on thee east flood pplain of the M Mississippi R River Valley. These unco onsolidated deposits d are underlain bby flat lying sandstone aand shales oof the Dreshbacch Group (Upper Cam mbrian). Th he Dreshbacch Group iis then undderlain by ddense Precambrrian crystallline rocks encountered e d at approxiimately 6500 feet below w ground suurface (BGS). At A the subjeect site, the bedrock b surfface is encouuntered at ann elevation of approxim mately 509 feet AMSL nearr the Reactorr Building and a slopes too approximattely 501 feet AMSL neaar the river shoreline.

8.5.3.3. Seism mology Many fau ults have beeen mapped d in the site region. Noone of thesee faults are considered to be capable in i accordancce with 10 CFR C 100, Appendix A A. Per the N NRC, Theree are no geoologic condition ns in the sitee vicinity thaat represent hazard to thhe facility. N Numerous ffaults are maapped in the sitte region, buut investigatiions of all of these faultts during thee course of vvalidating seeveral nuclear power p plant sites in the region, in ad ddition to sttudies for thee LACBWR R, have not ffound any evid dence of cap pable faultin ng. Additio onally, the aarea is one oof relativelyy low seism micity.

Therefore, capable faaulting does not need to be considereed in the anaalysis of thiss site (17).

Seismic activity a (maagnitudes ran nging from 3.53 to 5.4) thhat has beenn recorded between 19755 and 2008 all occurred oveer 180 miless from the sitte and did noot impact thee plant site oor operationss.

8.5.4. Hydrology H and Hydrogeeology Hydrolog gy and hyd drogeologicaal informattion was pprimarily obbtained from m Referencce 10.

Groundw water beneath h the site iss first encouuntered at deepths ranginng from approximately 15 to 25 feet BGS B and the water table aquifer is in n strong hyddraulic comm munication w with the adjacent Mississip ppi River. Therefore, T ch hanges in thee water tablee elevation aare dependennt on the staage of the Missiissippi Riverr. Groundwater in the sh hallow depo sits and fill m material likeely flows tow wards the west and discharg ges into the Mississippi M River. The deeper grouundwater is aalso likely too flow towards the west bu ut then may turn and flo ow parallel to the riverr. Based onn a review oof the groundw water elevatio on measurem ments colleccted during routine sam mpling in suppport of thee G-3 fossil staation, it appeears that theere is a slighht downwarrd vertical ggradient. Hoowever, therre are some perriods where the gradien nts are reverrsed and thiis is likely ddue to high river stagess and flooding..

Hydrauliic conductiviity is influen s structuree and grain size distribuution. Becauuse of nced by the soil the shalloow sands thaat were hydrraulically dreedged, deposited, and coompacted onn site, the intternal structure of the shalllow soils wo ould not likeely influencee groundwatter flow direection. How wever, 8-8

La Crossse Boiling Water W Reactorr License Termination T Plan Revisionn0 the nativ ve sands und derlying the hydraulic fill fi would likkely providee sufficient structure thaat the anisotroppy of the aqu uifer would be more perrmeable andd have a highher hydrauliic conductivvity in the horizontal directiion than in th he vertical direction.

d Thhis decreasess the verticaal transport w within these layers.

The veloocity of grou undwater flo ow is directlyy related to both the hyydraulic conductivity annd the gradient. The gradieent of the waater table is influenced bby the topoggraphy and w with the flat areas across th he site it is likely that thee water tablee has a very low gradiennt. Thereforre, it is likelyy that the groun ndwater velo ocity across the site is also relativeely slow (i.ee., in the incches and feeet/day range) evven though th he hydraulicc conductivitty could suppport faster flflow.

8.6. Environmen E ntal Effects ofo Decommiissioning 8.6.1. Summary The evalluation of th he environmeental effects (or impactss) of the deccommissioniing of LACB BWR follows the t approach h and method dology outliined and desscribed in N NUREG-05866. This apprroach includes identificatio on of environmental issu ues as eitherr generic or site-specificc. If the isssue is considereed to be gen neric, it is assigned a a significance level of eithher Small, Moderatee, or Large. If identifieed as genericc, the enviro onmental im mpact is conssidered to bee bounded bby the evaluatioon in NUREG G-0586 whicch concludess that the ovverall impactt significancee is Small.

For thosse environm mental issues or deco ommissioninng activitiess that requuire site-speecific evaluatioon, a standard d approach isi followed. It is summaarized as folllows:

1) The T issue or activity is summarized, s including a summary oof the impaccts as reportted in NUREG-019 N 1 and D-Plaan/PSDAR. Note that m many decom mmissioning activities arre not id dentified in these t documments.

2) Applicable A reegulations, permits, limitts or other reegulatory reqquirements aare identifiedd.

3) Potential imp pacts from deecommission ning activitiees relating too the environnmental issuue are described.

4) An A evaluatio on is perforrmed. Thiss includes analysis annd professionnal judgment to esstimate or determine d whhether the activity is likkely to makee a noticeabble impact oon the ennvironment considering the availab ble informatiion. If an im mpact is likkely, existingg and addditional miitigation meaasures that can c be takenn are evaluaated. If an iimpact cannnot be avvoided, a deetermination is made as to whether the impact iis likely to sseriously dam mage th he resource or o attribute.

5) A conclusion is reached.

A conclu usion is deriv ved from thee evaluation steps summ marized abovve. The connclusion idenntifies the level of significaance of the impacts. Siite-specific iissues are not bounded by the NUR REG-0586 evaaluation. No ote that the environmenta e al impacts oof the operatiing G-3 coall power plannt and the formeer G-1 coal/o oil fueled po ower plant was w not consiidered in thiss review.

Table 8-11 was used as the bassis for the site specificc environmeental impactt assessmennt for LACBW WR. It is exccerpted from m Table 6.1 ofo NUREG-00586. The ffirst step in this processs is to screen th he issues to identify site-specificc issues. D Decommissiioning activvities speciffic to 8-9

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 LACBW WR are then reviewed and a the activ vities that mmay requiree site-specifiic evaluationn are identifiedd. The screeening identtified the fo ollowing pootential areass for additioonal site-speecific evaluatioon:

Offsite land use activities:

a ch hanges in dem mographics and zoning tthat have occurred in thee past 35 yeears, since th he FES was issued.

i Aquaatic ecology affected by activities beeyond the opperational areea; changes in designatiion of sensittive areas.

Terreestrial Ecology affected by b activitiess beyond the operationall area; changges in designnation of sennsitive areass.

Threaatened and endangered species: ch hanges in loocal flora annd fauna annd designatioon of threattened and en ndangered sp pecies that have h occurredd in the pastt 35 years.

8.6.2. Radiological R l Effects of Decommissi D ioning 8.6.2.1. Occup pational Raddiation Exposure During decommissio d oning, Solutiions will con ntinue to immplement a R Radiation Prootection Proogram in accorddance with th he license sppecificationss and the reqquirements of 10 CFR 200. The objecctives of the Raadiation Protection Prog gram are to control radiaation hazardds, avoid acccidental radiiation exposurees and mainttain occupattional workeer exposuress to less thaan the adminnistrative lim mit of 2,000 mrrem/yr Totall Effective Dose D Equivaalent (TEDE E). Dose to workers andd the public must also be maintained m As A Low As Reasonably R Achievable A ((ALARA). The LACBW WR work coontrol program and proced dures will ensure e that work speciifications, ddesigns, worrk packagess and Radiation n Work Perm mits (RWP) involving po otential radiaation exposuure or handliing of radioaactive materialss incorporatee effective raadiological controls.

c In Augusst 1987, Dairryland placeed LACBWR R in a SAFS STOR condittion (a periood of safe stoorage of the staabilized and defueled faccility). LAC CBWR remaiined in a fullly SAFSTO OR conditionn until 1994 witth the comm mencement of o incrementtal decommiissioning acttivities. Thhis period off time allowed for the decaay of most short-lived s radionuclides r s, which subbsequently rreduced radiiation levels at the facility.. This delay y, combined d with the efffective impllementation of the Radiiation Protectioon Program and ALARA A measures,, minimized the actual and projecteed radiation dose exposuree during thee decommisssioning of LACBWR L tto date. It is anticipateed that the most significannt contributoors to occupational dose from remaiining dismanntlement actiivities will bbe the removal and packag ging of remaaining Reactor Buildingg Structuress, Systems, and Compoonents (SSCs).

The currrent occupattional expen nded and do ose expecteed to compllete the deccommissioninng is estimated d to be 130.33 Rem, whicch is well bellow the NUR REG-0586 eestimate. Ass the occupattional dose for the decomm missioning will w meet thee regulatoryy standards oof 10 CFR 220, it is therrefore bounded by NUREG G-0586 and th he impact is considered as Small.

8.6.2.2. Offsitte Radiation Exposure an nd Monitorinng Dairyland implementted a regulattory compliaant Radiologgical Environnmental Moonitoring Proogram (REMP) at LACBW WR which provided p an nnual report s with asseessments of the radioloogical environm ment in and around a the environs of thhe site. Thee REMP proggram providdes assurancee that the radiooactive gaseeous (airborrne) and liq quid effluennt releases dduring plantt operationss and decommiissioning acttivities do not exceed th he concentratation limits oof 10 CFR 200, the dose llimits of 10 CF FR 50, Appen ndix I, or the fuel cycle dose limits of 40 CFR 190. Solutioons will conntinue to adheree to these limits l througghout the co ourse of thee decommisssioning. C Consequentlyy, the public doose from deccommissioniing is bound ded by the crriteria in NUUREG-0586 and the imppact is considereed as Smalll.

The only y authorized effluent releease pathway y for the discharge of treeated and filltered radioaactive liquid waaste from th he LACBWR R site to the Mississippii River is thrhrough the sseal well/difffuser piping which w is a paart of the G-33 circulating g water dischharge system m. Currentlyy, the liquid wwaste collectionn system pu umps are nott operable. The T only liqquid effluentt discharges at LACBWR R are through the t East Tu urbine buildiing sump ussing an air ooperated pum mp. The aiir operated ppump dischargees to the inleet of the liquuid waste mo onitor, whichh is still operrable. Contiinued appliccation of the current c and future Rad diation Prottection and REMP at LACBWR R ensures ppublic protection in accordance with 10 CFR 20 0 and 10 CF FR 50, Apppendix I. RE EMP reportts for LACBW WR to date co onclude thatt the public exposure e as a result of ddecommissiooning activitties is bounded by the evalu uation in NU UREG-0586, which conccludes the im mpact is miniimal.

The gaseeous pathwaay (which includes i nobble gas andd particulatee) analysis iis subject too the meteorollogical condiitions during g the time off the release.. Due to plaant shutdownn and cessatiion of noble gass, the gaseou us pathway consists c of airborne a partticulate only and presentts a minor reelease or exposu ure pathway y. Routine aira samples area collected to determinne the dose ddue to radioaactive gaseous releases.

r 8.6.2.3. Enviro onmental Efffects of Acccidents and D Decommissiooning Eventts Decomm missioning acccident analy ysis is integ gral to the liicensing dessign basis foor LACBWR R and this analyysis has con ntinued durin ng shutdown n and decom mmissioning.. Post-fuel accident anaalysis conducteed and proviided in regu ular updates to the D-Pllan/PSDAR,, within section Plant Post-Fuel Acccident Analy ysis have no oted that wwith considerration for the current staage of LACB BWR decommiissioning and d with spentt nuclear fueel now storedd in the ISFS SI, this analyysis confirms that the minimal radioacctive material resulting from LAC CBWR operaation and remaining onn the LACBW WR site is in nsufficient for f any potential eventt to result iin exceedingg dose limiits or otherwisee involving a significantt adverse effe fect on publicc health andd safety.

The deco ommissionin ng of radioaactively conttaminated SSCs will innvolve the hhighest dose rates and contamination leevels remain ning at LAC CBWR. Worrker safety iis addressedd in the Radiiation Protectioon and Safetty and Health Programss for LACB BWR which rely on AL LARA principles.

8-12

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 The safety of the pu ublic is principally relatted to potenntial hazards associated with an airbborne release of radioactivee materials during d decommmissioningg operations.

During decommissio d oning, Solutions will perfform deconttamination annd dismantleement of SS SCs in addition to maintenan nce, waste management, m , and surveilllance activitties. The accidents discuussed in NURE EG-0586 asssociated witth immediatte dismantlinng would allso be appliicable durinng the decommiissioning off LACBWR R. Consequ uently, the ppotential deecommissionning accidennts at LACBW WR are bound ded by the accident evaaluation pre sented in N NUREG-05866. Howeverr, the potential consequencces associateed with thosse accidents would be lless at LAC CBWR due tto the reductionn of the totall radionuclidde inventory at LACBWR R from:

Deco ontamination n efforts mad de before deccommissioniing, Prior radioactive waste shipm ments, and Radio oactive decaay.

Operation nal accidents during deccommissioning could ressult from equuipment failuure, human eerror, and serviice condition ns. With thee spent nucleear fuel rem moved from tthe LACBW WR site and sstored in the ISFFSI, operatioonal acciden nts during decommissionning can be ccategorized aas follows:

Radio oactive wastte transportattion acciden nts, Explo osions and/oor fires assocciated with explosive andd/or combusstible materiaals, Loss of contamin nation contro ol, Naturral phenomeena, and Human caused ev vents externaal to LACBW WR.

The publlic dose conssequences reeported in NUREG-0586 N 6 for onsite, non-fuel rellated radioloogical accidentss during deco ommissionin ng ranged froom 0.02 to 00.96 rem. A An analysis oof potential ppublic dose con nsequences from f accidennts during LACBWR L deecommissionning was prrovided in thhe D-Plan/PSD DAR and ressulted in dosse ranging from 0.027 too 0.065 rem. The NURE EG-0586 acccident analysis is i therefore bounding b for the decomm missioning oof LACBWR R.

8.6.2.4. Storagge and Dispo osal of Low--Level Radiooactive Wastte The deco ommissionin ng of LACB BWR has, and a will coontinue to reequire the ddisposal of large volumes of low leveel radioactive waste, inccluding contaaminated eqquipment, toools, clothingg and bulk debris materialss such as con ncrete, metaal and asphallt. Materialss that cannott be free releeased are, and will continu ue to be disp a low level radioactivee waste. Through the proper positioned as implemen ntation of th he Waste Maanagement Program and associated pprocedures, S Solutions ennsures the approopriate segreegation, classsification, processing, p ppackaging, sshipment andd control of solid and liquid radioactive wastes.

The majo ority of the Class A low w level radiooactive wastee from LAC CBWR will bbe shipped tto the EnergySo olutions dispposal site in Clive, Utah h. Waste w will be loaded into approopriate contaainers and truck ked to a raail trans-load d facility in n Winona, M MN where the waste ccontainer wiill be transferreed to a rail car.

8.6.2.5. Radioological Criteeria for License Terminaation Followin ng the com mpletion of decontamin nation, dism mantlement and remeddiation activvities, radiologiical surveys will be perfformed to demonstrate tthat the dosse from residdual radioacctivity remainin ng in backfiilled structu ure basemen nts, any rem maining pipiing and soiils at LACB BWR (excludin ng the ISFSII) meets the unrestricted use criteriaa specified inn 10 CFR 200.1402. Afteer the radiologiical conditions are demo onstrated to beb below thee unrestricteed use criteriia, the 10 CFFR 50 license will w be terminated, with the exceptio on of the areea around the ISFSI. LT TP Chapter 5 and Chapter 6 provide th he methodo ology for deemonstratingg compliancce with the unrestrictedd use criteria.

8.6.3. Non-radiolog N gical Effectss of Decomm missioning 8.6.3.1. Onsitee Land Use The enviironmental impact i assocciated with onsite land uses has beeen determinned by the N NRC, within seection 4.3.1 ofo NUREG-0 0586 to be generically g c onsidered ass a Small iimpact.

The LAC CBWR deco ommissionin ng project iss located annd executed within the boundary oof the existing LACBWR L licensed prop perty previou usly used foor power genneration; all work is exppected to be con nducted with hin the LSE footprint. Some S onsitee roads have been refurbbished. No bbarge slips are being consttructed. Thee existing raail line suppported the opperation of tthe facility. The onsite raail line will be modified d and refurb bished with a rail spur to support ddecommissiooning activitiess. Containeers will be unloaded u an nd loaded onnsite. Onsiite activitiess such as veehicle parking anda equipmeent/container laydown, storage, s stagging and waaste loading are and conntinue to occur in a manner similar to when w the faciility was opeerational.

Several structures s su uch as the Switchyard, S Administrattion Buildingg, Crib Houuse as well aas all roadwayss and rail liines, will reemain at license terminnation. Subsurface baseement structtures, including g piping and d tunnels, beelow the 636 foot elevaation will bee radiologicaally assessedd and remediated, as necesssary. All otther systemss and compoonents as weell as all struuctures abovve the 636 foot elevation will w be remo oved during the decomm missioning pprocess and disposed off as a waste strream.

No sign nificant environmental changes asssociated w with the sitte-specific ddecommissiooning activitiess are anticipaated. In add dition to NRC C requiremeents, decomm missioning aactivities will also comply with w applicaable United States Envirronmental Prrotection Aggency (USE EPA) and W WDNR regulatorry requiremeents.

In accord dance with thet guidancee presented in NUREG--0586, the ppotential imppacts to landd use onsite aree considered d as Small.

8.6.3.2. Offsitte Land Use (in the Vicin nity)

Only areeas within th he existing site licensed boundary w will be used to support ddecommissiooning and licen nse terminatiion activitiees (such as temporary sttorage and sstaging areass for remediiation and dem molition equip pment, wastte containers, etc.). Off the 163.5 aacre site, abbout 1.5 acrees are 8-14

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 located within the fence-enclo osed LSE, where mostt work is expected too be conduucted.

Appropriiate isolatio on and con ntrol measurres will bee instituted to preventt the spreaad of contamin nation from the LSE areea to the ad djacent LAC CBWR propeerty as welll as offsite aareas.

These measures m willl also be moonitored to ensure e theirr effectiveneess. Thus, nno environm mental impacts associated with w the usse of offsitee lands are anticipated from the ddecommissiooning activitiess at LACBW WR.

Land in thet vicinity of the LACB BWR site iss predominaantly rural annd undeveloped. Of thee area within a five-mile radius, r approoximately one third is water and bbottomlandss included inn the Upper Mississippi M River R Nationnal Wildlifee & Fish R Refuge. WD DNR has deesignated thhe La Crosse-B Bad Axe Riv ver Basin Waatershed as a Geographiic Managem ment Unit (GM MU) and Veernon County hash establish hed a Land & Water Ressource Man agement Plaan (18), adddressing landd use, water quality and pro otection of the t environm ment within this GMU. The commuunity of Gennoa is located within w the Bad B Axe Riv ver Watersheed. Approx imately 36%  % of the La Crosse-Badd Axe basin lannd use is agriicultural andd over 50% ofo the land iss forested. TThere is an inncreasing shhift of some of thet agricultu ural land to recreational r land l use, sim milar to otherr parts of rurral Wisconsiin.

The clossest municip pality to the LACBWR site is the village of G Genoa, approximately 1 mile north of the site, acro oss from thee north-southh running H Highway 35. This small rural comm munity with a po opulation of 258 consists of various residences, farms, and a few retail businesses iin the valley beelow the easttern bluff.

Decomm missioning acctivities are not n being performed in aany land areas adjacent tto the site orr near the Refuge at the so outhern boun ndary of the site. Also,, public acceess to the boat launch aat the southern end of the site will be minimally impacted i duuring decommmissioning by rail and truck traffic enntering or leaving the site. Consequ uently, the ooffsite land areas are noot affected bby the decommiissioning acttivities and thet potential impacts to lland use offssite are conssidered Smaall.

8.6.3.3. Waterr Use LACBW WR is located d on the shorres of the Miississippi Riiver. The M Mississippi Riiver and its Thief Slough tributary t exttends along the LACBW WR site forr 3,000 feett from northh to south. The predomin nant water usage u duringg the operaation of LAC CBWR wass the use off water from m the Mississip ppi River as condensate cooling water. With thee plant shut ddown and fuuel removed from the reacttor, river waater is not currently c beeing used ass a cooling medium foor reactor orr fuel systems. River wateer does supp ply the Loww Pressure annd High Preessure servicce water systems.

Water pu ulled from on nsite wells will w support decommissiioning taskss and this waater will conntinue to be processed onsitte and dischaarged in acco ordance withh the sites state dischargge permits.

For a distance of 40 0 miles dowwnstream of the site, virrtually all m municipal w water suppliees for towns an nd cities alonng the Mississsippi River are obtainedd from groun und water. T The nearest uuse of river watter for industtrial purposees, excludingg the adjacennt G-3 fossill plant, is thhe coal-fired plant in Lansin ng, Iowa, ab bout 15 milees downstreaam of the siite. There aare no otherr known useers of river waater for indu ustrial purpo oses betweeen the LAC CBWR site and Prairiee du Chien,, WI, 40 miles downstream m.

The LAC CBWR site has its own n potable waater supply, provided thhrough a sinngle groundw water well at th he site. Thee locations ofo all wells (active and abandoned))are illustratted in Figuree 8-5.

Potable water w use duuring decomm missioning operations o iss not expectted to be significantly grreater 8-15

Sanitaary wastes aare collectedd in a solids hoolding tank and pumpeed off by a local state permitted ssanitary wasste hauler. This includes a sanitary holding tank that servicess the Adminnistration Buuilding and a sanitary hoolding tank thatt services th he LSE Turb bine Buildin ng. Storm water runofff is diverteed directly tto the Mississipppi River at a outfalls. Release arreas are perriodically m monitored foor oil sheenn and discoloraation. Roof drains are either discharrged to the gground area surroundingg the facilityy thru downspo outs or through the norm mal effluent release r pathwway after proocessing thruu an oil sepaarator located innside the LS SE. Conseq quently, in acccordance w with NUREG G-0586, the ppotential im mpacts to water use u are conssidered Smaall.

8.6.3.4. Waterr Quality This secttion evaluattes potentiall project efffects on thoose portions of the natuural environnment related too surface water w and grroundwater. Surface w water generallly refers too streams, riivers, ponds, reeservoirs and d lakes. At LACBWR, the nearby bbodies of waater are the M Mississippi RRiver to the weest and the Refuge R wetlannds to the so outh.

The env vironmental impact evaaluation associated with th surface aand groundw water quality in section 4.3.3 4 of NUR REG-0586 haas been deteermined to bee generally aapplicable too LACBWR R with a Small impact.

At LACB BWR, all non-radiologiccal water discharges to thhe Mississipppi River aree controlled uunder its WDN NR permits. Water maanagement programs p annd practicess have beenn implementted at LACBW WR which meet m the Gen noa sites WDNR W Wiscconsin Polluutant Discharge Eliminnation System (WPDES)

( ass well as LAACBWRs WDNR W Tier III Industrial Storm Wateer General PPermit and WDN NR Wastew water Permit. In additio on, impacts to the Misssissippi Riveer will be grreatly reduced through im mplementation of approp priate Best Managemennt Practices (BMP) forr soil erosion and sedimentation control during d deccommissioninng operatiions. D During decommiissioning, sttorm water run-off r from m active imppacted areass undergoing remediatioon or demolitioon will be monitored m andd controlled if necessaryy.

Radiolog gical impacts are minim mized throug gh adherencce to Off-sitte Dose Callculation Manual (ODCM)) limits and d assessed th hrough the REMP andd the grounddwater monnitoring proggram.

Potentiall onsite grou undwater im mpacts are monitored m byy the routinne sampling of 10 permanent onsite monitoring weells at LACB BWR. Representative ggroundwaterr samples arre obtained ttwice per year for radiolog gical analysis purposes when grounndwater connditions are at low and high elevationns. The plan nts networkk of down grradient wellss (five paireed wells: MW W-200A/B; MW-201 A/B; MW-202A A/B; MW-203A/B; and MW-204A/B M B) are situateed around thhe key LACB BWR buildingss in appropriate locatio ons and quaantity to inntercept andd detect conntamination from LACBW WR former prrocess areas and potentiaal release poiints.

As the water w from the Mississsippi is no o longer useed to cool operating pplant system ms at LACBW WR, the therm mal impact to o the Mississsippi River hhas been elim minated.

No adverrse impacts on surface waterw and grroundwater aare expectedd from the im mplementation of decommiissioning acctivities. Co onsequently,, the potentiial impacts to surface and groundw water quality arre bounded byb NUREG--0586 and co onsidered S Small.

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 8.6.3.5. Air Quality The enviironmental impact i evalu uation assocciated with air quality iin section 4.3.4 of NUR REG-0586 hass been determ mined to be generally g applicable to LLACBWR w with a Smalll impact.

LACBW WR complies with all app plicable Fedderal and Staate air qualiity regulatioons, includinng the requiremments of the WDNR W and the Wiscon nsin Bureau oof Air Manaagement, and will impleement BMP to minimize m fu ugitive dust during d demo olition and d ecommissioning activitiies. Air emiission sources such s as the plants diessel generatorrs are no lonnger in servvice and havve been rem moved from the facility.

Fugitive dust will be generatted from various v decoommissioninng activitiess, includingg the demolitio on of concrete building g structures and the exccavation of soil. Careful planningg and controlled demolition n and dismaantlement tecchniques, wiith appropriaate assessmeents by Soluutions Radiation n Protection n, Environmeental, and Safety S and HHealth staff, will be connducted to ennsure excessivee or harmfu ul dust emisssions are no ot generatedd. As necesssary, measuures such ass dust suppressiion by mistin ng water willl be used to mitigate dust emissionss.

Appropriiate Health anda Safety assessments and a controlss will also bee establishedd during exppected extended d periods of operation to o ensure thaat personnell and the ennvironment aare not adveersely impacted d by exhaust emissions.

No adverrse impacts on air quallity are expeected from tthe implemeentation of ddecommissiooning activitiess. Consequeently, the potential impaacts to air quuality are boounded by N NUREG-05866 and considereed Small.

8.6.3.6. Aquattic Ecology The env vironmental impact evaaluation asssociated witth aquatic eecology in section 4.3.5 of NUREG--0586 has been b determ mined to be generally appplicable too LACBWR R with a Sm mall impact.

The aquaatic habitat at a LACBWR R includes th he area fromm the intake structure inttegral to thee Crib House att the shorelline to the diffuser stru ucture that extends outt into the M Mississippi R River approxim mately 110 feet fe from thee shoreline. Habitats asssociated wiith this areaa were previously disturbedd during thee initial construction of o the facillity. Howeever, the im mplementatioon of decommiissioning activities is no ot expected to disturb eexisting aquuatic habitatss, their floraa and fauna in the Mississsippi River and also neearby River tributaries, streams andd wetlands. The removal of the diffusser structure,, which shares a line witth the G-3 foossil station, is not plannned.

Various fresh water fish speciees, macro-invertebrate ppopulations, and vegetaation exist w within these aqu uatic environments. A 1980 study y indicated tthat the poppulation of ffish near thee site included 53 species and a 19 famillies (19).

Plans forr the demollition of stru uctures at LACBWR L ddo not incluude the remooval of wasste or equipmen nt by barge. Consequen ntly, there is no impact too the shorelinne from thiss type of actiivity.

Solutionss will contin nue to main ntain WDNR R permits annd decomm missioning opperations wiill be performeed within ap pplicable limmits. Protecttion of the nnearby Refuuge wetlandss and habitaats is, 8-17

The poteential impactts to the aqu uatic ecology y beyond thee site boundaary have alsso been evaluuated and considered to be Small.

8.6.3.7. Terresstrial Ecologgy The enviironmental im mpact evaluuation of terrrestrial ecoloogy in sectioon 4.3.6 of NNUREG-0586 has been deteermined to be b generally applicable to o LACBWR R with a Sm mall impact..

No know wn terrestriial exotic or o invasive species hhave been nnoted to ooccur withinn the decommiissioning prroject area. To minimize the introoduction off exotic or iinvasive speecies, appropriaate BMPs arre, and will continue c to be b followed.

The land d around LA ACBWR wass initially dissturbed by th the constructtion of the ffacility, incluuding the formaation of abo out 27 acres by filling riv ver edge andd low forestt areas with material dreedged from thee Mississipp pi River. Therefore, th he site shoreeline no lonnger resembles the shorreline prevalentt in surround ding areas. Given the extensive e lannd disturbancce, construcction and yeaars of operation ns associated d with G-1 and G-3 ass well as LA ACBWR, thhe terrain has not suppported onsite haabitats for many m plant an nd animal sp pecies, incluuding endanggered or invasive speciees. In addition, with the sh hort-term natture of the work w associaated with deecommissionning and thee fact that the direct d heavy construction n and demolition projecct area is sepparated from m the Refugee area to the sou uth, no direcct impacts too any off-sitee sensitive sppecies are annticipated. S Since the plaanned demolitio on activities do not inclu ude the remo oval of wastee or equipm ment by bargee, there is also no anticipateed impact to o the shorelinne.

8.6.3.8. Threaatened or End dangered Sp pecies The poteential impactts to Threaatened or E Endangered species aree bounded bby NUREG--0586 and considered Smaall.

A review w of the U.S.

U Fish an nd Wildlife Service lissting, the F Federally-Lissted Threattened, Endangeered, Propossed, and Candidate Speecies County ty Distributiion (21) conncluded that only two speccies are desig gnated as TThreatened or Endang ered withinn Vernon Coounty, the coounty which LA ACBWR ressides in:

A mussel m speciees, Higgins eye pearly ymussel (Laampsilis higgginsii), withh habitat inn the Missiissippi Riverr: Endangerred.

A plaant species, Northern monkshood m (Aconitum nnoveboranceense), with habitat in nnorth-facing slopes: Th hreatened.

No noted d adverse im mpacts to aqu uatic species have been nnoted during plant operattions. In genneral, due to thhe siting and operation off the LACBW WR facility,, as well as tthe previous G-1 facilityy, and the existiing G-3 fosssil station, thhe majority of o the licenssed site, situuated betweeen the Mississsippi River to the west and d the rail line and Highw way 35 to thee east, is devveloped and does not suupport terrestriaal or aquatic habitats wh hich may be inhabited byy threatenedd or endangeered species. The presence of the Higg gins eye peaarlymussel in mussel beeds in the viicinity of LA ACBWR haas not been notted. A musssel survey of o the Thieff Slough rivver area wass conductedd in 1978 annd no Higgins eyee pearlym mussels were found.

Likewisee, the Northeern monksho ood has not been noted on or in thee vicinity of LACBWR. The Wisconsiin Departmeent of Agriculture, Traade & Conssumer Proteections Enddangered Sppecies Habitat Program P (222) has noted that the Norrthern monkkshoods habbitat is leachhed sandstone and limestonee cliffs overr creeks and d streams an nd the plant is present iin the Whiteestown and Stark township ps within Veernon County y. This hab bitat is not ppresent withiin or near thhe LACBWR R site for this plant p species to be impaccted by decom mmissioningg operations.

The Pereegrine Falcon n (Falco perregrinus) weere put on thee Wisconsinn Endangeredd and Threattened Species list l in 1975 and starting g in 1993, Dairyland suppported recoovery effortss with installlation of falcon n nesting boxxes at its faccilities, inclu uding at the G G-3 stack, too support chhick hatchingg and protection (23). Oveerall, Peregrine Falcon restoration r pprogram effoorts resulted in the bird bbeing delisted in 1999 (24 4); however, Dairyland has continueed to mainttain the G-3 nesting sitee and hatching efforts. SinceS the G-3 G facility will still ccontinue opeerations andd the LACB BWR decommiissioning wiill not interffere with G--3 operationns or its stacck, there is no impact tto the falcon recovery efforrt and populaation.

8-19

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 8.6.3.9. Occuppational Issu ues/Safety Occupatiional issues/safety has been evaluateed to be bounnded by NU UREG-0586 and the imppact is considereed Small.

The enviironmental impact i evaluuation assocciated with occupationaal issues in section 4.3.10 of NUREG--0586 has been b determ mined to be generally appplicable too LACBWR R with a Sm mall impact. While decom mmissioning g involves in ncreased induustrial activiities and safe fety focus, siimilar programss addressing g worker saffety were im mplemented during the operation off the facilityy and also duriing repair annd refueling outages. The T occupatiional issues and safety impacts assessed are thosee related to o human heealth and saafety, includding impactts from phyysical, chem mical, ergonommic, and biolo ogical hazard ds. Radiolog gical impactts were discuussed in secttion 8.6.2.

Solutionss is commiitted to deccommissioniing LACBW WR safely through thee applicatioon of contractoor health andd safety prog grams to effeectively conttrol hazards in the work environmennt and prevent occupational o l injuries and illnesses. Contractor health and ssafety progrrams will coomply with federal and staate regulatio ons including g Wisconsinn Departmeent of Laborr and the U United States Occcupational Health H and Safety S Admiinistration (OOSHA) requuirements.

Typical contractor safety practtices and communicati c ions will innclude actioons such ass the followingg:

Safetty training ass a part of th he site accesss program foor all employyees and subb-contractorss.

Safetty emphasis as the first to opic of discuussion at meeetings.

Proviiding all worrkers with a Health and Safety S bookllet.

Work ker training and requireed certificatiions review w prior to asssignment too tasks requuiring speciific worker qualification q ns. Certain specialty s subbcontractors are mobilizzed, as necesssary, such as heavy equ uipment dem molition firm ms.

Obtaiining and rev viewing Safe fety Data Sheeets for chemmicals boughht onsite.

Invollving Health h and Safetty staff in reviewing and approvving decomm missioning work packaages and parrticipating in n pre-job wallkdowns, woork conditionn assessmennts and review ws.

Issuin ng periodic safety messages to com mmunicate aw wareness off significant safety issues and lessonns learned.

Holding safety stand-downs s s whenever serious saffety events occur to communicatee and reinfo orce safety events e and leessons learneed site-wide..

8.6.3.10. Cost A detaileed discussion n of the site decommissiioning projeect costs is ppresented in Chapter 7 oof this LTP.

8.6.3.11. Socioeconomic Im mpacts LACBW WR was shut down in 19 987 as the sm mall size off the plant ddid not makee it economiically efficient to operate. By 1994, so ome incremeental decomm missioning pplanning andd activities bbegan with som me projects associated with the removal r of the RPV iin 2007 and other meetallic 8-20

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 radioactiv ve componeents over th he past 7 yeears. A sm mall ISFSI ffacility holdding 5 caskss was completeed by 2012. Staff size att the plant haas graduallyy been reduceed as operattions ceased,, with periodic spikes in workforce hirring to suppo ort specific project needds (e.g. 40 ppersonnel staaffing the ISFSII project) (25).

More acctive decom mmissioning and structtural demoliition is antticipated inn the 2016--2017 timeframme. Some of o the labor tasks requiire specializzed skills annd equipmennt which wiill be obtained from outsid de Wisconsiin; however,, some of thhe workforce will be coomprised off craft personneel from the lo ocal and reggional areas surroundingg the site. O Overall, the ddecommissiooning activitiess will have a short-term m positive ecconomic imppact on the local comm munity due tto the increased d use of the local craft workforce w and a opportunnities for loccal businessses to supporrt the project an nd workers with w suppliees and services.

Therefore, the socio oeconomic impact i is evvaluated to be boundedd by NURE EG-0586 andd the impact iss considered Small.

8.6.3.12. Enviroonmental Ju ustice The perccentages of low-incomee and minority groups w within the VVillage of G Genoa as weell as Vernon County C are quite q low, approximatel a ly 3%, and lower than those in largge cities (e.g. La Crosse) and a more po opulated Wisconsin coun nties furtherr from the L LACBWR siite (26) (27). No impact to o the greater population, including sp pecial groupps, is expecteed.

Decomm missioning acctivities will cause slightt increases iin truck trafffic to and froom LACBW WR to transportt equipment and debris. The truck traffict will uuse existing main street routes, prim marily Highway y 35 traversin ng north-sou uth by the siite. There will be no eenvironmenttal justice im mpact relative to rail and truuck transporrtation as a reesult of decoommissioninng.

There is no reason to believe that low-in ncome and m minority poopulations w will be adveersely impacted d by the deco ommissionin ng project. Per NUREG G-0586 and this evaluattion, the poteential site speciific impact is considered d Small.

8.6.3.13. Culturral, Historic,, and Archeoological Resources A review w of the National N Parkk Service National N Reggister of HHistoric Placces (28) thrrough May 2015 and the Wisconsin W Historical H So ociety (29) ththrough Mayy 2015 identtified only a few historicall sites in Veernon County y and no strructures in thhe village of Genoa or w within 5 milles of the plantt. The closeest historicall site with prre-historicall structural rremnants is the Goose IIsland Archeolo ogical Site neear Stoddard d, WI. locateed approximaately 7 miless north of thhe LACBWR R site, which waas certified by b the Nation nal Park Serrvice in 19800 (30).

Also, as indicated in n NUREG-0191, the Staate of Wiscoonsin has plaaced three hhistorical maarkers along Highway 35 in n Vernon Co ounty. One is i about a haalf mile nortth of LACBW WR, overloooking the USACE Lock an nd Dam No. 8. It descriibes the origgin of the prresent system m of locks oon the Upper Mississippi.

M The T second,, about 7.5 miles m south oof the plant,, highlights tthe Battle off Bad Axe. Th he third wass adjacent to o LACBWR R and commeemorates the plant itsellf as Wisconnsins first nucllear generatiing plant. In n 2009, crewws erected a new, updatted Wisconsiin state histoorical marker at the waysid de across Hig ghway 35 fro om the site ((31). This neew location resolved seccurity concerns associated withw having a public-acccess marker oon Dairyland property.

La Crossse Boiling Water W Reactorr License Termination T Plan Revisionn0 Dairyland sent an un nused controll rod to the Wisconsin W H Historical Muuseum in Maadison, WI w which presents the control rodr and a reeplica fuel asssembly (322); however, there is no objective too save or catego orize any parrt of the LAC CBWR plantt as a historiical site.

Land diisturbance fo or the remov val of large componentss will be minnimized as tthe waste w will be primarily y shipped viaa rail.

Land thaat was disturrbed for projjects beyond d the nucleaar operationaal areas (e.gg. associatedd with the consttruction and d demolition of the G-1 fossil statioon and the construction of the G-3 fossil station) were w perform med in acco ordance witth applicablee permits annd includedd appropriatee soil erosion controls c and stormwater pollution prevention plaans.

Based on n the historiccal information presenteed in NUREG G-0191 andd the current approach foor the transporttation of sysstem compon nents and waste, w the deecommissionning will haave no signifficant impact on n cultural, historic, and archeologica a al resources.. Consequenntly, as bounnded by NUR REG-0586 an nd based upon u this evaluation, thet potentiaal impacts to Culturaal, Historic, and Archaeollogical Reso ources are coonsidered Sm mall.

8.6.3.14. Aesthhetics The enviironmental impact i evalu uation assocciated with aaesthetics inn section 4.33.15 of NUR REG-0586 hass been determ mined to be generally g applicable to L LACBWR w with a Smalll impact.

The impaact of decom mmissioning on site aesth hetics (e.g. vvisual skylinne) is limitedd in terms off land disturban nce and duraation. These impacts aree temporary and will ceaase when deccommissioniing is completeed. Once alll of the majo or plant strucctures and buuildings eastt of the Misssissippi Riveer are removed, the aesthettics will imp prove slightly y by providiing a more oopen view oof the Mississsippi River. The T final deetermination on usage of o the decom mmissioned property wiill be made upon completion of the deccommissioning.

Therefore, the enviro onmental immpact associiated with aeesthetics is evaluated too be boundeed by NUREG--0586 and th he impact is considered Small.

8.6.3.15. Noise The enviironmental impact i evalu uation assocciated with nnoise in secttion 4.3.16 oof NUREG--0586 has been determined to be generaally applicab ble to LACB BWR with a Small imppact.

LACBW WR is located d on the sho ore of the Mississippi M RRiver, 300 fefeet from thee river bankk, and 475 feet west of the rail road lin ne. USACE E land and L Lock and D Dam No. 8 arre located oon the north sid de and a porttion of the Upper U Mississsippi River National W Wildlife & Fish Refuge oon the south sid de. There arre no residen nces within 1,000 1 feet off the station structures aand no schoools or hospitals within 1 mile.

m The nearest comm munity, the village of G Genoa, Wiscconsin is loocated approximmately 1 milee to the north h of the plannt.

Noise geeneration wiill primarily result from m demolitionn activities involving heeavy construuction equipmen nt. Noise associated with w decomm missioning aand shipmentt of waste iss intermittennt and temporarry and will occur prim marily durin ng daylight hours. Onnce the deccommissioninng is completee, noise levells in the viciinity of the LACBWR L ssite will be rreduced to leevels below those experiencced during th he operationn of the faciliity.

8-22

La Crossse Boiling Water W Reactorr License Termination T Plan Revisionn0 Due to the t distancee of the stattion from seensitive receeptors, theree will be liimited temporary impacts on noise levels l durin ng decommissioning annd demolitiion activitiees. Duringg the decommiissioning, Solutions S agrrees to com mply with aany noise liimitations (ee.g. quiet hhours) imposed by the Villaage of Genoaa.

Therefore, the envirronmental impact assocciated with noise is evvaluated to be boundeed by NUREG--0586 and th he impact is considered Small.

8.6.3.16. Irretriievable Reso ources The enviironmental im mpact evalu uation associiated with irrretrievable rresources in section 4.3.18 of NUREG--0586 has been b determ mined to be generally appplicable too LACBWR R with a Sm mall impact.

During th he demolitio on and structural disman ntlement of the station, recycling annd asset recoovery efforts will w be madee. Some meetals from th he site are an anticipated too be released as clean sscrap.

Low leveel radioactiv ve waste hass been and will continuue to be shippped to the EnergySoluutions disposal site in Clivee, Utah. Th his facility has h sufficientt space for tthe disposal of this wastte. In addition, any Class B/CB waste th hat is generaated will be sshipped to thhe WCS faccility in Anddrews, Texas.

As statedd in NUREG G-0586, irretrrievable reso ources that wwould occur during the ddecommissiooning process are a the materrials used to decontamin nate the faciliity (e.g., raggs, solvents, gases, and toools),

and fuel used for con nstruction machinery m and d for transpoortation of m materials to aand from thee site.

These reesource com mmitments are consideered to be minor and are neitherr detectablee nor destabilizzing.

Therefore, the enviro onmental im mpact associiated with irrretrievable resources iss evaluated to be bounded by NUREG G-0586 and th he impact is considered Small.

8.6.3.17. Traffic and Transp portation The enviironmental impact i evalu uation assocciated with ttransportatioon issues in section 4.3.17 of NUREG--0586 has been b determ mined to be generally appplicable too LACBWR R with a Sm mall impact.

The num mber of shipm ments and th he volume off waste shippped are greaater during ddecommissiooning than during the operation of th he facility. Non-radioloogical impaccts of transpportation include increasedd traffic and wear and tear on roadw ways. It is annticipated thaat there will be no signifficant effect on n traffic floww or road weear. There will w be no raadioactive w waste shipmeents executeed via barge traaffic. The existing barg ge traffic on the Thief S Slough brancch and the M Mississippi R River support the t operating g G-3 fossil station and are not assoociated with LACBWR ddecommissiooning operationns.

Therefore, the enviro onmental immpact associated with trransportationn is evaluateed to be bouunded by NURE EG-0586 and d the impactt is considereed as Smalll.

8.6.3.18. Cumu ulative Impaccts Cumulatiive impact iss defined thee impact on the environnment whichh results from m the incremmental impact off the action when w added to other passt, present, aand reasonabbly foreseeabble future acttions.

La Crossse Boiling Water W Reactorr License Termination T Plan Revision n0 The cum mulative impaacts were assessed by first determinning the resoources affectted by LACB BWR decommiissioning. These includee surface water w and grooundwater, air quality, aquatic ecoology, terrestriaal ecology. Irretrievablle resourcess were alsoo evaluatedd from thee perspectivve of cumulativ ve impact.

Past, prroposed an nd future foreseeablee actions include coonstruction, operation and decommiissioning off coal-fired powerp plantts and recreaational use of the land as access tto the Mississip ppi river for boating. Th he individuall impacts off the LACBW WR decomm missioning oon the resourcess listed abo ove were alll determineed to be miinor. The ppast, presentt and futuree site activitiess are not projjected to sig gnificantly acccumulate ennvironmentaal impacts thhat would in total, over time, exceed th he minor im mpact of the individual aactivities onn the affecteed resources. The major irrretrievable reesource attriibutable to LACBWR L ddecommissiooning was thhe use of lannd for disposal of low lev vel radioactiv ve waste. NoN future acctivities willl involve rradioactive w waste disposal and will therrefore have no n cumulativ ve effect.

In summary, the cum mulative impaact to site reesources is prrojected to bbe minor.

8.7. Overview O of Regulation ns Governing Decommiissioning Acctivities and d Site Releasse 8.7.1. Federal F Requ uirements Decomm missioning acctivities that are subject to t federal reggulations incclude:

8.8. Conclusion C

As previo ously evaluaated in the D-Plan/PSDA D AR, the non- radiologicall environmenntal impacts from decommiissioning LA ACBWR are temporary and a not signiificant. Thee potential issues identifiied as site-specific in NU UREG-0586 have been evaluated aand there is no significaant impact. The potential environmen ntal impacts associated with w decomm missioning L LACBWR hhave already been predictedd in and willl be boundeed by the previously isssued enviroonmental im mpact assessm ments (NUREG G-0191, NUR REG-0586, and a D-Plan/P PSDAR). T Therefore, thhere are no nnew or signifficant environm mental changges associateed with decom mmissioningg.
