1 EXECUTIVE SUMMARY ES.1 Introduction The North By Wter Reuse Authority s (NBWRA) Memer Agencies nd the U.S. Deprtment of Interior, Bureu of Reclmtion (Reclmtion) hve prepred this Drft Environmentl Impct Report/Environmentl Impct Sttement (Drft EIR/EIS) for the North Sn Plo By Restortion nd Reuse Project. The North Sn Plo By Restortion nd Reuse Project hs een developed in conformnce with the requirements of the Reclmtion s Pulic Lw , Title XVI, including preprtion of Fesiility Study, nd pssge of Sente Bill For the purposes of this EIR/EIS, this project or ction will e referred to s the North By Wter Recycling Progrm (NBWRP). This EIR/EIS hs een developed to provide the pulic nd responsile nd trustee gencies reviewing the NBWRP n nlysis of the potentil effects, oth eneficil nd dverse, on the locl nd regionl environment ssocited with construction nd opertion of the NBWRP. The sic purpose of the NBWRP is to provide recycled wter for griculturl, urn, nd environmentl uses nd to promote the expnded eneficil use of recycled wter in the North By region. Implementtion of NBWRP would include upgrdes of tretment processes nd construction of pipelines, pump sttions, nd storge to distriute recycled wter for use in complince with Article 4 in Title 22 of the Cliforni Code of Regultions, which sets wter qulity stndrds nd tretment reliility criteri for recycled wter. This EIR/EIS considers No Project, No Action nd three Action Alterntives. The Action Alterntives consist of tretment, trnsmission, nd storge fcilities necessry to meet rnge of recycled wter demnd scenrios within the NBWRA service re through Ech Action Alterntive considers vrying levels of recycled wter use, nd corresponding levels of regionl fcility integrtion. The Alterntives considered re s follows: No Project Alterntive, ssumes tht the proposed project is not implemented, nd reviews two scenrios: 1) considertion of existing conditions without the project, no uild scenrio ; nd 2) considertion of resonly foreseele future conditions without the project. This second scenrio is identicl to the No Action Alterntive, identified elow. No Action Alterntive, provides future without the project scenrio s seline to compre the impcts of the proposed Action Alterntives. Alterntive 1, Bsic System, includes use of recycled wter ner ech of the individul wstewter tretment plnts (WWTP); North Sn Plo By Restortion nd Reuse Project ES-1 ESA /

2 Alterntive 2, System, dds dditionl pipelines, pump sttions nd storge to prtilly connect the existing WWTPs; nd Alterntive 3, System, provides fully integrted recycled wter distriution system connecting ll four Memer Agency WWTPs. The Memer Agencies hve collectively prioritized the projects within their individul service res to estlish n Implementtion Pln identifying the order in which projects would e constructed. Phse 1 of the Implementtion Pln includes projects tht re defined to level of detil tht llows for project-level environmentl review. The Phse 1 Implementtion Pln represents the set of projects, common to ll of the NBWRP lterntives, nd would likely e the first phse implemented under ny lterntive. ES.1.1 Purpose nd Need of the Proposed Action The mission of the Bureu of Reclmtion is to mnge, develop, nd protect wter nd relted resources in n environmentlly nd economiclly sound mnner in the interest of the Americn pulic. The Bureu of Reclmtion's wter reclmtion nd reuse progrm is uthorized y the Reclmtion Wstewter nd Groundwter Study nd Fcilities Act of 1992 (Title XVI of Pulic Lw ). Also known s Title XVI, the ct directs the Secretry of the Interior to undertke progrm to investigte nd identify opportunities for wter reclmtion nd reuse of municipl, industril, domestic nd griculturl wstewter, nd nturlly impired ground nd surfce wters, nd for design nd construction of demonstrtion nd permnent fcilities to reclim nd reuse wstewter. The NBWRA is coopertive progrm in the Sn Plo By region tht supports sustinility nd environmentl enhncement y expnding the use of recycled wter. The purpose of the NBWRP is to provide recycled wter for griculturl, urn, nd environmentl uses therey reducing relince on locl nd imported surfce nd groundwter nd reducing the mount of treted effluent releses to Sn Plo By. ES.1.2 Project Ojectives In ddition to the purpose nd need for the proposed Federl Action, the following project ojectives hve een developed y the NBWRA for the NBWRP. The project is proposed to promote the expnded eneficil use of recycled wter in the North By region to chieve the following ojectives: Offset urn nd griculturl demnds on potle wter supplies; Enhnce locl nd regionl ecosystems; Improve locl nd regionl wter supply reliility; Mintin nd protect pulic helth nd sfety; Promote sustinle prctices; Give top priority to locl needs for recycled wter, nd; North Sn Plo By Restortion nd Reuse Project ES-2 ESA /

3 Implement recycled wter fcilities in n economiclly vile mnner. All of the Memer Agencies lredy hve existing recycled wter progrms. The NBWRA nticiptes tht provision of recycled wter from the Proposed Action will e mde ville for use to new nd existing wter customers on resonle terms nd conditions. As pproprite, fee structures for recycled wter hve een or will e developed y Memer Agencies within the context of ech gency s rules, regultions nd finncil plnning. ES.1.3 Proposed Federl Action As implementtion of the Project would likely require externl funding ssistnce, the investigtion nd development of the Project is eing crried out in conformnce with the requirements of the U.S. Deprtment of the Interior s Bureu of Reclmtion Pulic Lw , Title XVI, which provides mechnism for Federl prticiption nd cost-shring in pproved wter reuse projects. The proposed Federl Action is the provision of federl funds y the Bureu of Reclmtion under the Title XVI Progrm to NBWRA Memer nd Cooperting Agencies for the implementtion of wter recycling projects exmined in this EIR/EIS. The Bureu of Reclmtion is the NEPA Led Agency for this proposed ction. Reclmtion intends to use this EIR/EIS to consider provision of federl funding under Title XVI for implementtion of NBWRP. As led Federl gency, Reclmtion would use this EIR/EIS to support Record of Decision, which would document Reclmtion s decision to choose one of the lterntives including the proposed ction nd no ction. The NBWRA Memer Agencies nd cooperting gencies my use this EIR/EIS to pprove the NBWRP, or components of the NBWRP, mke Findings regrding identified impcts, nd if necessry, dopt Sttement of Overriding Considertions regrding these impcts. SCWA will ct s CEQA Led Agency. Individul NBWRA Memer Agencies nd cooperting gencies re Responsile Agencies s provided for under CEQA nd my use this EIR/EIS for the pproving the proposed components (i.e., Phse 1) in their respective service res. ES.2 Project Bckground Five prticipting gencies orgnized themselves under Memorndum of Understnding (MOU) in August 2005 s the NBWRA. Additionl gencies supporting the NBWRA through contriution of funds nd stff time include North Mrin Wter District (NMWD) nd Np County. The following Memer Agencies form the NBWRA nd would prticipte in the implementtion of NBWRP: LGVSD LGVSD provides wstewter tretment nd disposl service to pproximtely 30,000 people within the re of Mrinwood, Lucs Vlley, Terr Lind, Snt Veneti, Los Rnchitos, nd Smith Rnch Rod (LGVSD, 2005). Novto SD Novto SD provides wstewter tretment nd disposl services to pproximtely 60,000 residents within the city of Novto, n re of 28 squre miles, nd surrounding res (Novto SD, 2006). North Sn Plo By Restortion nd Reuse Project ES-3 ESA /

4 SVCSD The SVCSD WWTP egn opertions in 1954 nd provides service to out 34,000 people in the city of Sonom, within 7-squre-mile re (SVCSD, 2006). Np SD The Np SD s Soscol Wter Recycling Fcility (SCRF) trets wstewter from the city of Np nd surrounding unincorported communities, n re of out 23 squre miles, nd serves popultion of pproximtely 80,000 (Np SD, 2007). SCWA SCWA, which egn the Title XVI process for investigting recycled wter distriution system under Coopertive Agreement with the Bureu of Reclmtion, is drinking wter provider to over 600,000 residents nd continues to e n ctively prticipting prtner. ES.2.1 Supporting Agencies NMWD NMWD hs prtnered with Novto SD to implement recycled wter projects in their collective service res, including 0.5 million gllons per dy-tertiry tretment fcility locted t the Novto SD reclmtion fcility. NMWD is contriuting funds nd stff time to NBWRA. Np County Np County is cooperting with Np SD in the development of recycled wter options for the Milliken-Srco-Tulucy (MST) Creeks res, nd is contriuting funds nd stff time to NBWRA. ES.2.2 Fesiility Study Preprtion The NBWRA memers undertook coopertive plnning efforts over 5-yer period, including 19 i-monthly technicl workshops s well s monthly institutionl workshops with extensive outrech to potentil NBWRP stkeholders to define shred ojectives nd develop fesile lterntives towrd definition of region-wide wter reclmtion nd reuse project tht would enle them to meet those ojectives. Under the MOU, Cmp Dresser McKee, Inc. (CDM) prepred Phse 1 Engineering Fesiility Report (2005) nd Phse 2 Engineering Fesiility Study Report (2006) in coordintion with NBWRA. The Phse 3 Engineering nd Economic/Finncil Anlysis Report (or Phse 3 Report) completed in June 2008 updted the Phse 2 Fesiility Report to e consistent with project plnning conducted y the individul Memer Agencies, included n economic nd finncil nlysis, nd discussed potentil environmentl effects. ES.2.3 Wter Supply Setting nd Future Conditions The ction re encompsses pproximtely 318 squre miles of lnd within Mrin, Sonom, nd Np Counties. This region extends roughly 10 to 15 miles inlnd of the tidl Sn Plo By, with totl popultion of over 270,000 in the mjor urn centers of Sn Rfel, Novto, Sonom, nd Np. The region supports griculture, including some of the premier wine-grpe growing lnd in North Americ, s well s light industry, commercil nd institutionl uses, prklnds, nd residentil res. North Sn Plo By Restortion nd Reuse Project ES-4 ESA /

5 Locl nd regionl plnning projections indicte tht pproximtely 10 to -12 percent of growth would occur in most of the existing urn centers in the ction re y the yer 2020 (s compred to 2005 popultions). Existing policies in principl cities will tend to fvor concentrted rther thn dispersed growth. Agriculturl lnd use is expected to remin reltively constnt over 20-yer plnning period. The locl governing policies in the Mrin, Sonom, nd Np Counties in the ction re protect griculturl lnds. Given the high vlue of wine-grpe culture, it is unlikely tht there would e much chnge in the 75 percent of griculturl crege committed to vineyrds. Totl urn wter use including oth residentil nd non-residentil uses in the project re is projected to increse from the 2005 level of 63,700 cre-feet per yer (AFY) to out 72,800 AFY in Totl wter use for irrigtion of griculturl lnds is estimted t pproximtely 23,300 AFY t present. The sources tht serve these wter demnds include surfce wter supplies (oth within nd outside of the ction re), groundwter, nd recycled wter. SCWA supplies much of the Sonom nd Mrin County re with surfce wter conveyed from the Russin River nd its triutries in centrl Sonom County, djcent to the project re wtershed. SCWA s relile supplies to customers in the ction re consist of 87,970 AF of wter during dry yer. Groundwter serves griculturl users (nd some residentil users) s primry source of supply, prticulrly in the MST re of Np County. Groundwter lso serves s secondry source of supply for some urn users s well, including the City of Sonom, Vlley of the Moon Wter District, nd SCWA contrctors. Although the totl quntity of groundwter in the ction re is unknown, groundwter pumping hs een mesured. The vst increse (i.e., 80 percent) in pumping of groundwter in the pst 30 yers to support griculturl irrigtion hs resulted loclly in groundwter outflow exceeding inflow, some impcts on groundwter qulity, nd lowering of groundwter levels in some prts of the ction re tht re dependent on groundwter supplies. Existing tretment nd distriution infrstructure in the ction re currently llows for out 7,300 AFY of recycled wter for irrigtion nd wetlnds restortion purposes, which could increse to 11,250 AFY y The verge yer nd wet seson conditions pper to yield sufficient surfce wter nd groundwter to meet totl nnul demnd in the ction re. However, the sesonl vilility of some wter sources (ginst the strong sesonlity of griculturl demnd), the potentil for overdrft of groundwter with impcts on qulity nd quntity, nd the growth pressures on the re s urn centers suggest need for n effective, coordinted, nd regionl pproch to the incresed use of recycled wter.

6 ES.3 Description of Project Alterntives ES.3.1 Project Loction The ction re, illustrted in Figure ES-1, extends pproximtely 10 to 15 miles inlnd from the Sn Plo By within Mrin, Sonom, nd Np Counties. The ction re extends s fr south s Point Sn Pedro in Mrin County, nd s fr north s Milliken Cnyon locted 28 miles to the northest in estern Np County, nd encompsses out 318 squre miles of lnd. Urn centers in the ction re re Sn Rfel (county set) nd Novto in Mrin County, Sonom in Sonom County, nd Np (county set) in Np County. In order to form cndidte recycled wter projects, lnd use informtion nd Memer Agency recycled wter plnning documents were reviewed. Wter nd wstewter gencies in the ction re hve developed severl existing recycled wter projects nd identified recycled wter projects for future implementtion. Additionl potentil recycled wter project res were identified y grouping lnd uses either in mjor griculturl or lndscping res or in res etween existing nd proposed projects.

11 Novto South Service Are Hmilton Field Service to the Hmilton Field re would e estlished through implementtion of of 0.7 million gllons per dy (mgd) tertiry tretment upgrde t the existing LGVSD WWTP, construction of new ooster pump sttion onsite, nd construction y NMWD of pipeline distriution system from LGVSD north to serve the Hmilton Field re. NMWD would construct pipeline from the LGVSD WWTP to the Hmilton Field re long three route options: Option A: This option would consist of pproximtely 2.75 miles of pipeline tht would originte t the Recycled Wter Tretment Fcility t LGVSD WWTP, extend west djcent to the WWTP ponds nd northwest through grzing lnd. Option B: This option would consist of pproximtely 2.1 miles of pipeline tht would originte t LGVSD WWTP, extend west djcent to the WWTP ponds nd north long griculturl ccess rods through grzing lnd. Option C: This option would consist of pproximtely 2.15 miles of pipeline tht would extend north from LGVSD WWTP through grzing lnd. The lignment would turn west long St. Vincent s Drive then north, djcent to the Northwest Pcific Rilrod (NWPRR) right-of-wy. Novto Snitry District/ North Mrin Wter District Novto North Service Are Novto SD nd NMWD would implement service in the Novto North Service Are y incrementlly expnding tertiry cpcity t the existing Novto Recycled Wter Tretment Fcility from 0.5 mgd to 1.2 mgd. The recycled wter pipeline would e routed from Atherton Avenue to Olive Avenue under Highwy 101, nd north on Redwood Boulevrd to Sn Mrin Drive. A seprte pipeline would e routed on H Lne to serve the Vlley Memoril Prk Cemetery. A ooster pump would e instlled t Atherton Avenue nd the distriution system would e connected to the existing 0.5-MG Plum Street Tnk, which would e rehilitted to provide recycled wter storge. Novto Centrl Service Are Novto SD nd NMWD would implement service in the Novto Centrl Service Are through construction of recycled wter distriution system from the Novto SD WWTP south to Rowlnd Boulevrd nd the Vintge Oks shopping center, nd cross Highwy 101 to serve urn users west of Highwy 101. The tretment fcilities t the Recycled Wter Tretment Fcility would e decommissioned nd relocted to the Novto SD WWTP. From the WWTP, n 18-inch pipeline would e instlled long Novto SD s existing esement, with jck nd ore crossing of US 101 from Rowlnd Boulevrd to Redwood Boulevrd. An 18-inch recycled trunk line would then extend north through Novto to deliver recycled wter to Novto High School nd other irrigted plying fields, with 10-inch line extending south long Redwood Boulevrd. North Sn Plo By Restortion nd Reuse Project ES-11 ESA /

12 A new pipeline would connect the WWTP with the North Service Are pipeline in Olive Drive vi Le Drive or McClellnd Drive. This would llow continution of recycled wter service to the Stone Tree Golf Course nd the other customers in the North Service Are during the course of the reloction of the recycled wter fcility to the WWTP. This intertie would lso incorporte the Plum Street Tnk into the distriution system serving oth the Novto North nd Centrl Service Ares (Nute Engineering, 2006). SVCSD Sonom Vlley Recycled Wter Project (SVRWP) The Phse 1 Implementtion Pln includes specific elements of the SVRWP, including construction of 5.2 miles of pipeline, dditionl storge t the SVCSD WWTP nd construction of dditionl pumping cpcity for distriution. The Phse 1 Implementtion Pln includes SVRWP Alignment 1A, which would consist of pproximtely 5.2 miles of pipeline in western Sonom Vlley. The min pipeline would originte from the SVCSD WWTP, extend southwest nd then northwest through vineyrd to Arnold Drive. The pipeline would continue north long Arnold Drive to Ornge Avenue, nd extend north on Ornge Avenue to Elm Avenue. The pipeline would then continue est on Elm Avenue, cross field to Arnold Drive, extend north on Arnold Drive, nd end just north of Leveroni Rod. Secondry pipelines or segments would extend from the min pipeline on the following rodwys: Highwy 116, Wtmugh Rod, nd Leveroni Rod. SVCSD Np Slt Pond Pipeline Under Phse 1 of the NBWRP, SVCSD would construct pipeline to provide recycled wter to Pond 7 nd 7A for hitt enhncement. Proposed fcilities in the Np Slt Mrsh re include construction of new pipeline from the existing SVCSD WWTP to the existing SVCSD storge reservoirs locted ner the intersection of the Northwestern Pcific Rilrod Authority (NWPRA) nd Rml Rod. SCWA hs identified three potentil route options, which re descried elow. Option A: This option consists of instlltion of pproximtely 4.0 miles of 24-inch pipeline tht would e instlled from the reservoirs to Pond 7 nd 7A. Approximtely 1.0 mile of pipeline would extend from the reservoirs long the south side of NWPRA rilrod trcks to Skggs Islnd Rod, t which point the pipeline would cross to the south side of the rilrod trcks nd continue est long the south side of the rilrod trcks for pproximtely 0.4 miles. At this point, the pipeline would cross to the north side of the rilrod trcks nd continue est long the north side of the rilrod for pproximtely 0.9 miles, then cross to the south side of the rilrod trcks. The pipeline would extend 1.7 miles until it reches the ccess rod for Ponds 7 nd 7A, which includes pipeline instlltion south long the ccess rod for pproximtely 4,200 feet, terminting t the mixing chmer. This option is consistent with the pipeline route reviewed in the Np River Slt Mrsh Restortion Project EIR/EIS (JSA, 2004). Option B: This option consists of instlltion of 4.5 miles of 24-inch pipeline from the reservoirs to the slt ponds. Approximtely 0.25 miles of pipeline would e instlled north long n ccess rod to Rml Rod. The lignment would then extend 1.75 miles est long Rml Rod. At this point, the pipeline would trnsverse est long n griculturl ccess rod for pproximtely 1.25 miles until it reches Buchli Sttion Rod. The pipeline North Sn Plo By Restortion nd Reuse Project ES-12 ESA /

13 would then run south on Buchli Sttion Rod for pproximtely 1.25 miles, until it reches the Huichic Creek entrnce of the Np-Sonom Mrshes Wildlife Are (NSMWA) nd the ccess rod for Ponds 7 nd 7A. Option C: This option would consist of 4.7 miles, nd would follow the ove Option B route for pproximtely 3.0 miles (from the reservoir, est long the ccess rod to Rml Rod, nd long Rml Rod). However, the pipeline would then extend south pproximtely 0.3 miles to ccess n existing reservoir. At this point it would trnsverse 0.4 miles est to Buchli Sttion Rod (Figure 2-6). The pipeline would run south on Buchli Sttion Rod for pproximtely 1.0 mile, until it reches the Huichic Creek entrnce of the Np-Sonom Mrshes Wildlife Are (NSMWA) nd the ccess rod for Ponds 7 nd 7A. Np SD The Phse 1 project in the Np SD service re would provide recycled wter distriution system to ddress groundwter overdrft in the Miliken-Srco-Tulucy (MST) re of Np County. MST Are Project The MST Are Project would consist of 17.5 miles of new pipeline, four ooster pump sttions long the pipeline routes, nd new ooster pump t the WWTP. The new pipeline would e instlled from the end of the Strelow Drive pipeline through the Np Stte Hospitl grounds nd north to the MST re. A looped system using existing rodwys would e constructed, with one segment extending west long First Avenue nd the second segment extending est long Third Avenue; oth segments would then merge long Hgen Rod north of the Np Vlley Country Clu. Four ooster pump sttions would e instlled to mintin pressure throughout the distriution system, nd n dditionl pump would e instlled t the WWTP. Pump sttions would e locted on Imol, Wild Horse Vlley Rod, Est 3rd Avenue, nd 3rd Avenue. Potentil recycled wter users include the Np Stte Hospitl, the Np Vlley Country Clu, nd griculturl nd residentil prcels long the proposed pipeline route. Under the MST Locl Project (Options 1 nd 2), more direct pipeline system extending north from Imol Avenue long 4th Avenue, Coomsville Rod, 2nd Avenue nd terminting t the Np Vlley Country Clu would e implemented. Tle ES-3 identifies projects tht would e implemented s Phse 1 Projects under ny of the Action Alterntives considered. Alterntive 1: Bsic System Alterntive 1 Bsic System would expnd recycled wter progrms currently in opertion within ech of the Memer Agency service res. It puts gretest emphsis on the service of locl demnds y the individul WWTPs. Alterntive 1 would provide 6,655 AFY of new recycled wter for irrigtion use nd 5,825 AFY for hitt restortion, nd would include instlltion of 83 miles of new pipeline, construction of fcilities onsite t the existing WWTPs to provide n dditionl 7.8 mgd of tertiry tretment cpcity, nd development of pproximtely 1,020 crefeet of new storge, primrily t existing or plnned storge ponds t the WWTPs.

No Project Alterntive No project elements would e implemented under this lterntive. For discussion of the No Project under future conditions, see No Action Alterntive elow. No Action Alterntive The No Action Alterntive ssumes tht there would e no joint project mong the memer gencies. It represents the current sttus in which dditionl wstewter tretment cpcity nd wter recycling occurs strictly from the implementtion of locl plns for expnsion, nd the potentil need to develop dditionl potle wter supplies continues to e regionl chllenge. In generl, ech Memer Agency would continue to implement individul recycling projects, suject to the vilility of funding nd completion of the CEQA process. The No Action Alterntive would likely result in smller increment of wter recycling projects within the region. Specific projects tht would hve the gretest potentil to e implemented under the No Action Alterntive re elow: LGVSD. LGVSD would prioritize expenditures on projects tht meet its NPDES permit requirements. For the purpose of this EIR/EIS, it is ssumed tht this strtegy would result in no dditionl recycled wter projects eing implemented in the LGVSD service re. Novto SD. Novto SD nd NMWD would pursue implementtion of recycled wter distriution fcilities solely within the Novto North Service Are. This includes 4.4 miles of pipeline, 0.5 mgd upgrde t the Recycled Wter Tretment Fcility, nd one pump sttion t the intersection of Atherton nd Olive. SVCSD.

17 ES.4 Summry of Potentil Environmentl Impcts nd Mitigtion Mesures The impcts re nlyzed for construction nd opertion of the NBRWP for the individul Memer Agencies in complince with oth CEQA nd NEPA. Phse 1 impcts re discussed t project level nd impcts from the Action Alterntives re discussed t progrm level. While the project lterntives re designed to provide recycled wter to offset potle wter supplies nd chieve the project ojectives discussed ove, these lterntives lso would result in some short-term nd long-term impcts to the environment. Tle ES-6, included t the end of this section, summrizes the environmentl impcts ssocited with ech of the project lterntives. For impcts determined to e significnt, mitigtion mesures re presented nd the impct significnce fter mitigtion is shown. The environmentl impcts ssocited with the project lterntives cn e generlly ctegorized s follows: project construction; project opertion; climte chnge; nd growth-inducement. ES.4.1 Construction Most environmentl impcts identified for the project lterntives would e ssocited with project construction; these impcts would occur s individul projects re implemented y Memer Agencies, nd would cese once project construction is completed. Construction impcts include effects ssocited with trnsport of construction mterils nd equipment nd crrying out construction ctivities such s excvtion, grding, foundtion development, pving, nd uilding of structures. Construction ctivities generte impcts such s noise, dust, impcts to sensitive species or wetlnd hitts, temporry effects on griculturl ctivities, construction trffic nd ccess disruption, incresed erosion, or incresed potentil for spill of hzrdous mterils used in construction (such s fuel, or pint) nd relted wter qulity issues. In some cses, construction effects were found to e less thn significnt nd in other cses they were determined to e significnt. In ll cses, fesile mitigtion mesures hve een identified to reduce construction impcts to less thn significnt levels. There would e no significnt nd unvoidle construction impcts. ES.4.2 Project Opertions Project opertionl effects relte primrily to the distriution nd use of recycled wter. These impcts re generlly less thn significnt, or mitigle to less thn significnt level, nd include: exposure of fcilities to geologic hzrds; reduction of the mount of treted effluent dischrged to triutries of North Sn Plo By; incresed impervious surfce res; exposure of fcilities to 100-yer flood events; eneficil effects to groundwter, wter supply, nd hitt enhncement; conversion of frmlnd to non-griculturl uses; potentil impcts to groundwter qulity; incresed use of electricity to pump recycled wter to end users; incresed greenhouse gs emissions; loclized noise increses; loclized use of tretment chemicls; eneficil potle wter offset; ltertion of designted scenic vists or views; disproportionte effects to minority communities; nd cumultive effects. All of these potentil impcts were reduced to less thn significnt level of incorportion of the mitigtion mesures identified in Tle ES-6. North Sn Plo By Restortion nd Reuse Project ES-17 ESA /

18 ES.4.3 Climte Chnge This Drft EIR/EIS exmines the potentil for the project lterntives to increse greenhouse gs emissions, which in turn would contriute to glol climte chnge effects. As glol concern, increses in greenhouse gses contriute to cumultive impcts, rther thn constituting direct impct ssocited with single project. This Drft EIR/EIS lso reviews se level rise nd the potentil for incresed flooding cused y climte chnge to ssess how the project might ffect or e ffected y these environmentl chnges. Project construction nd opertion would result in incresed greenhouse gs emissions. Construction emissions would e short-term. Greenhouse gs emissions ssocited with project opertion would result primrily from recycled wter distriution. The project lterntives would not conflict with ny mesures dopted y the stte or other gencies to implement the Cliforni Glol Wrming Solutions Act of 2006 (AB 32), the stte lw tht requires the Air Resources Bord to design nd implement mesures to reduce greenhouse gs emissions to 1990 levels y With respect to the potentil effects of climte chnge, the project increses the flexiility of locl nd regionl wter supply systems to dpt to chnges in wter supply vilility. As descried in Chpter 1, Introduction, the NBWRA Memer Agencies hve initited progrms to promote sustinility nd implement energy efficiency nd wter conservtion progrms including locl recycled wter projects s mens of dptive strtegies to the effects of climte chnge. As prt of the proposed project, the NBWRA would expnd the recycled wter use in the North Sn Plo By region. As discussed in Section 3.11, Pulic Services nd Utilities, the proposed project would tret nd reuse the wstewter tht is otherwise dischrged to the Sn Plo By. The project would therefore offset the potle wter supply, mking n equivlent mount of potle wter ville for other uses. Given the incresed vriility in the precipittion nd thus, the wter supplies, the proposed project would hve eneficil effect on the wter supplies in the region. The proposed project would provide severl opportunities for mngement flexiility nd implementtion of dptive mngement strtegies to improve wter supply reliility. ES.4.4 Growth-Inducement None of the project lterntives would e directly growth inducing. However, the provision of recycled wter, like potle wter supplies, would ssist in meeting the wter supply needs identified for uildout of pproved Generl Plns within the region. As such, provision of recycled wter supply would hve the potentil to contriute to secondry effects ssocited with development under the pproved Generl Plns. The potentil environmentl effects of this future plnned growth hve een evluted nd fully disclosed previously in the CEQA environmentl documents prepred the Generl Plns for Sonom County, Mrin County, nd Np County. Both the Generl Plns nd the wter supply plnning documents for these res include policies encourging the use of recycled wter. North Sn Plo By Restortion nd Reuse Project ES-18 ESA /

19 ES.4.5 Significnt nd Unvoidle Impcts There re no significnt nd unvoidle impcts identified for the NBWRP, with the exception o of the NBWRP s contriution to potentil secondry effects of growth ssocited with development under the pproved Generl Plns with the region. ES.5 Issues of Known of Controversy nd Issues to e Resolved ES.5.1 Issues of Known Controversy Bsed on pulic nd gency comments received throughout the project plnning process, Reclmtion nd NBWRA hve identified the following res of controversy relted to the proposed NBWRP. Appendix 1, Scoping Report, summrizes ll of the issues rised y gencies nd the pulic during the pulic scoping process in July 2008 through August Ares of potentil pulic controversy include: the proposed end uses of recycled wter, eneficil offset; integrtion of conservtion mesures; regionl distriution of recycled wter; cost nd enefit; wter qulity; effects on griculturl uses; nd growth inducement. ES.5.2 Issues to e Resolved Reclmtion nd NBWRA will need to identify preferred lterntive. The decision will e sed on project enefits, potentil environmentl effects, nd numerous fctors including the type of finncing ville, permitting requirements, nd implementtion schedule. Other issues to e resolved include: Project design nd opertions will lso e refined y Memer Agencies through the environmentl permitting process, in prticulr complince with the federl nd stte Endngered Species Acts, which will lso ffect the overll project enefits. The selection of n lterntive lso determines the level nd type of environmentl impcts, s descried in this Drft EIR/EIS. Regrdless of which lterntive is selected for implementtion, detiled design of project fetures nd plnning of construction will need to e coordinted with mitigtion requirements so tht sensitive resources in the project res re voided where prcticle. The methods for chieving required mitigtion would e determined during detiled project design through consulttion nd coordintion with the permitting gencies. Completion nd conclusions of the Federl Fesiility Report, descried elow in Section ES.7, including relted engineering design, economic (costs nd enefits), nd finncil nlyses s sis for determining the type nd extent of federl interest in project implementtion.
