REQUEST FOR CITY COUNCIL APPROVAL Cf REYISED SANTA CLARA COUNTY HAZARDOUS WASTE HANA.EMENT PLAN Member, of the Council: Report in Brief This report requests that Council adept I resolution approving the Revised County Hazardous Waste Manag£ment Plan (CHWMP}. The CHWMP was revised to address the specific item, that the State Department of Health Service, [DHS) criticized in their disapproval of the Plan that was SUbmitted by the County in August 1989. Revfsicns ~erf made t~ incl~de the requirement for cities to have a ~alardous waste management plan, to reflect the -fair share-policy regarding inter jurisdictional agreements. to significantly revise the siting cr1terii, provide additional risk assessment criteria, and to clarify the role of the lOCil Assessment Committee in the process of deciding when i risk assessment is needed. Modifications to the CHWMP ire contained in the attached July 3, 1991 ~emorandum from Santa Clara County. The CHWMP was distributed f~ the June 23, 1988 Council packet, and a copy is available f~r review in the City's Planning Oepartment. The County Board of Super~i$crs has requested each Sa~ti Clara County city to review and appro~e tne Revised C~ by August 15, 1991. final Board action on the CHWMP i1 scheduled f~r August 20. Background The County prepared 0 C~ and submitted it to DHS in August 1989 for approval, is required by AS 2948 [Tanner, 1986). DHS disapproved the Plan, but wos required by AB 2595 (Tanner, 1990) to olIo. the County to resubmit its revised Plan by June 20, 1991 which incorporates reVisions responding to DHS criticisms. DHS rejected the Santa Clara Co~nty's original Plan (and the plans of most counties) because of the inclusion of -fair share-language providing that the County could not be required to accept facilities with a capacity to treat more waste than was generated in the County. During the revision process, Assemblywoman lannir and the County Supervisors~ Association agreed on compromise -fair share-language. Because of the length of time it CMR:l73:91 • . -;,' - '. .-. t'lQk. tfl reach conStfl.SUS., OHS has a.greed' to allow Santa. (1 ira. County to submit Its pi,. after the Jun. 20 deadline.

The consensus language for the protection from suspected faults criteria is: "Hazardous wastE' management facilities sited within 3,000 feet of a known or suspected fault, as established by the Alquist-Priolo maps of the Staie of California or idnItifk4 in the most nCDltly A"4ila~1e locol ""'ps or information, shall con4uct" sJlbsurfaa explor"tion to determine that there are no active faults within 200 feet of the portions of:he facility where treatment, storage, or disposal will be conducted." U) CHA."IGES TO PRoncnoN OF WELLS AND WELL FlELDS CRITERIA (formerly SUPPLY WELLS AND WELL FIELDS) Based on consultation with the Santa Clara Vaney Water DiEmel. it was determined that non-drinldng water wells can also act as conduits for groundwater contamination. The definition of wells and well fields in Appendix Vlli-C was expanded to protect areas in th€ 90 day cone of depressions of drinking water, irrigation, remediation, and monitoring wells. TIte protection of wells a.nd well fields criteria still restricts siting of residuals repositories in such Meas, while other hazardous waste managment i.dli ties rna y be sited provided an effecti ve hydrogeological barrier to flow exists. The consensus language for the criteria and definition of protection of wells and well fields is: "Residuals repositories shaD not be located within the cone of depression created by pumping a well 0< well field (i"c!,,4e4 lIre 4rinking water, irrig"tion, And remediation ".4 monitoring wells) for 90 days.

(4) OiANGES TO GENERAL PLAN' CONSISTENCY Based on your recommendations, we modified the language on page 8-3 regarding the CHWMP's consistency with the General Plan as follows: "The CHWMP should be reviewed regularly and siting criteria revised when appropriate. All resulting changes to the CHWMP or siting criteria must be .pproved by • majority of the cities with a majority of the population within the inC01'portJte4 portion of the County in the same manner as required for its initial adoption. A formal update should be conducted every three years 10 correspond with the triennial update ol the State Plat. Any amendments shall be subject to the same public participation processes used to initially evaluate the CHWMP," (5) CHANGES TO PROTEcnON FROM UNSTABLE SWPES In response to your recommendations, the following language was added 10 the protection from unstable slopes criteria: "Hazardous waste management facilities should not be located in areas where slope exceeds 15 percent ,,,uss site-$ptcific factors mitigate the impact of the .it.'. s!ope, Facilities locating in such areas shall lequire appropriate land use designations," (6) COMBINING PROTEcnON OF PROXIMATE POPULA nONS .. IMMOBILE POPVLA:nONS,AND PUBUC FACILmES Two of the I:hesI. three criteria, protection of proxlmate populations and protection of immobile populations, have be<!n combined.

Changes have been parapJu-ased here. The exact wording can be found on the pages in the original Plan that are indicated aft...-each specific change. 1. Siting criteria that are more pem-Jssive: a. The original Plan states: Hazardous waste facilities shaH be located on major paved roads. (plan, pp. 8-12 and 8-19) Changes to this siting criter'.a would ,lIow a facility to be located, tD the maximum extent possible, in close proximity 10 major payed ToadS. b. The original PLln stateS: Hazardous waste facilities shall not be located in a!".as where slope exceeds 15%. (Plan,. pp. 8-14 and 8-21) Changed to: Facilities may be allowed if ·site-specific factors mitigate the impact of the site's slope." c. The original Plan states: Hazardous waste facilities shaH not be located in areas having particular cultural~ aesthetic, historical, Or archaeological significance. (Plan, pp. 8-13 and 8-20) Changed 10: Low-volume transfer and storage f.cilites may be allowed in such areas, if necessary to handle hazardous waste generated by visitors, workers, or residents, thereof. Other types of hazardous waste facilities would not be permitted. d The original Plan .tates: Hazardous waste management facilities shall no! be located on prime agricultunl lands. (Plan, pp. 8-13 and 8-20) Changed 10: Facilities may be sited on prime agriculturalJands if the 10cal jurisdiction makes a finding that an overriding public need is served by allowing ille facility to be located on the proposed site. 2. Siting criteria that are more restrictive: a. The original PLln states: Facilities shall not be sited within the cone of depression created by pumping of • well or well field for 90 days. ~"""'ell or well field" was originally defined as wells. used 10 extract underground drinking water supplies. (Plan, pp. 8-15 and 8-22; definition in Appendix vm.c) Changed to: Redefine "well or well field" to include "drinking water, irrigation, and remediation and monitoring wells." 2 , _-:::> - Q · 3. Minor language changes: These minor languag~ chang •• serve to clarify \he ir.tent and r"".uirements of .. particular siting criteria or provide consistency in language in \he document, but do not change the criteria. 4. Deletion of a criteria and a map: The criteria entitled 'Prolection of Existing Groundwater Quality." and its accompanying map, entitled "High Priority Proteclio" AIeas in Santa Oara County," have been d.leted. (Plan, pp. 8-15 and 8-21.; and map on p. 8-25) 5. A policy change: An additiona.! policy W'lS added to the Plan to clarify that the County Supervisors As.ociation of California (CSAC) "Fair Share" language used in the Pian is only operative in conjuction with interjurisdictional agreements. (Pian, p'. &-28) The original "Fair Share" language (developed jointly by the counties and CSAO in the County's Plan states that the County reserves the right to deny a land use permit for a facility proposed to be sited in the county if the volume of waste proposed to be managed at the facility is greater tllan the volume of waste that has been identiJied as the shortfall waste management capacity in the county. Since the original Plan was writfen, thl:? County has signed oil MemorandulI' of Understa. .. ,ding with the other eight counties within the Bay Area to form the ABAG RegionaJ Fair Share Allocation Committee. This Committee has been created to allocate the responsibility for siting the regionally-sized hazardous waste mana.gement facilities that will. be needed to serve idat..,tifed regional shortfalls i.i1 waste management capacity within the ABAG region. to the year 2000. The additionol policy language reflects a regional approach to facility siting. The Memorandum of Understanding states that: • the County will enter into interjuridictiona! agreements (with the eight other participating counties within the ABAG region) thaI would allow for the fair allocation of responsibility for the siting of needed hazardous waste ma.""'gement facilities; • and that, having established these agreements, Santa Oara County reserves the righllo deny • land use permit for a facility proposing to manage a volume of waste greater than !he identiJied waste management capacity shortfall of the County, unl ... the Counly has .greed, thrc>ugh an interjuridictional agreement, to accept responsibility for siting a facility whose volume exceeds the County's shm'lfall. 3 -.,.·-:1-...

Slope exceeding 15% This change would not be expected to result in an increased potential for a negative enviIo!'lII't_ental impact because those jurisdictions that allow similar industrial u..~. in areas where slope exceeds 15%, have experience in prescribing and evaluating the performance of the engineering co".tainment features, L'1Spections measures and other enviromental protection controls that would be required to mitigate any potential impacts. c Storage and tr.ansfu in a.reilS 01 ruItuzal signifiGlIlce This change would not be expected to result in an increased potential for a negative environmental impact because the change would allow a connnerdal hazardous waste operator to collect and transfer only those wastes that are already being generated In such an ..... ea. No treatment or disposal of hazardous wastes would be allowed In these areas, d. Prime agricultural lands This cha!1ge would not be expected to result in an Increased potential for a negative environmental impact because adequate policies and plans exist for protection of prime agric..utur.l land.

The main thrust of Government Code s..ctions 65965.1 and 66780.8 and Chapter 6.5 of the Div'-sion of tl,e Health and Safety Cooe (AB 2948, "Tanner Bill") is 10 provide for the siting of off-site hazardous waste management facilities in California. Provisions for the siting or expansion of on-site facilities are not covered under AB 2948. A$ disc.J.ssed in Chapter 7, new hazardous waste mana.gement facilities in the County·and expansions to existirlg fadlities w1'dch require preparation of an .ErR, a land use permit. and a hazardous waste facility pennit will be required to implement the County~s Hazardous Waste Management Hlerarchy to the maximum extent feasilile in the use, handling, and disposal of hazardous materials and wastes. To minimize the storage~ treatment, and disposal of hazardous waste in off-site facilities, the hierarchy suggests implementation of three preferred management practices (m order of priority): source redUction, recycling (on-site and off.-site), and on-sii:e treatment. However" l.!Se of the hierarchy will not r.ecessa.rily preclude the need for the siting of off-site hazardous waste management facilities due to the Counfy's large and varied waste ,tream. This chapter prcvides criteria for identifying general .reas in the County where facilities may be sHed pending compliane<> with coru;u-aints specific to the facility_ These candidate are .. were selected by overlaying the siting criteria which could be mapped with the industrial zone map, and identifying the resulting areas which appear to meet approriate criteria for the construction of an off-site hazardous waste managment facility_ More ,tringer.t criteria were applied to the siting of a residuals \ i I i ~ I I ;. ... ~ , \ , $-.\·c <',' -.-:', ... -' l 1 i rep05itories than fer other facilities. since residuals repositories pore a potentially greater risk to pubUc and environmental health. The sifulg criteria developed by the County to meet the statutory requirements of AB 2948 fall ir.to the following objectives: (I) protection of t.he residents of Santa Clara County; (2) assurance of the structural stability of :r.e facility; (3) protection of water resources; (4) protection of air quality; (5) protection of environmentally sensitive area5j and (6) protection of socia.l and eoonQmic goals. Siting criteria serve an important functian ir. the ph.nning process and in evaluating specific facility proposals. While the siting criteria satisfy t.he need for an emphasio on public and environmental safety, the CO\mty's siting policies ensure that Countywide facility sifulg needs and obj..:tives are met. These siting criteria and policies will be used to determine the appropriate facility design and performance standards required of a proposed hdlity, in addition to determining the aet:eptabillty of the selected site. The siting criteria are intended to apply to Countywide sifulg decisions, including siting decisions in individual cities. They are to be used whenever a land use decision is required to site and construct a new or expand an exisnng ofE-site hazardous waste management hanty. The criteria are designed to identify the most . . ~ appropriate locations in regards to public and envirorunental .. fely for needed hazardous waste management facilities. These criteria will help facility develo~ identify appropriate faa1ity location and understand t."e major issues of community concern in "any particular area.. ~--'. . . .:·t."" -', (I~ . --.". -... ~. :~~"" , .. ) .....• <,;-'; •• :"-'"'_ --: ,,: .. -; ~ .. ;.r:: "-..

All resulting changes 10 the CHWMP or siting criteria must be approved by. majority of the cities with • majority of the population within Lie incorporated portion of the COlmty in the same mannn as required for its irutiai adoption. A fonnal update should be conducted every three years to correspond with the triennial update of the St.te Plan. Any amendments shall be subject \0 the same public participation processes used to initially eValu'te the ClTh'MP. fACll.I1YSmNG POLICIES In the siting of future haza:'dous waete managem~nt facilit:i.es~ Santa Clara County recognizes that t.."1e storaget treatment.. indneration~ and disposal of hazardous waste is of e~treme ooncern to its residents. The following policies address the land use implications for siting these facilities in the County. These policies, in addition te the goals, policies, and objectives outlined in Chapter 2, are supported by the siting criteria described in this Chapter. Polic;y 1, All proposals to site a ~azardoU5 waste management facility shall assure oompatibility with neighboring land uses and be consistent ".;th the appropria:e permitting jurisdiction's General Plan, zoning, and the CH'VMP. Policy 2: Areas designated for industrial uses by the applicable General Plan may be appropriate for hazardous waste management facilities if, during the development review process, it is detenn.i.ned that such a use would be compatible with existing and planned land uses in the vicinity of the site. Urbanized areas designated for industrial",;os are not appropriate fer siting residuals repositories. Polic;y 3: As determined by the permitting jurisdiction, all proposals fDr new and 8-3 , ". I ". - expanded hazardous waSle management facilities must provide adequate mitigation for identified environmental impacts. Engineering alternatives are not I*.rmitled in the design oi.residuals repositories due to the polentially greater risk associated V¥ith these facilites to the community and the environment. Poliey 4; A risk assessment znay be required for new or e>:panded hazardous waste management facilities by the local jurisdiction based on the facility applicanrs response to the risk assessment cheekEst. The risk assessment should identify health, safety and envirorunental factors that may be unique to the site as well as te the type of wast. te be managed. Polic;y S: AIl proposals for hazardous waste faciUties should be consistent with plans and policies of regional regulalory agencies (Le. BAAQMD and the RWQCB) that protect air and water quality. Polic;y 6: The representation on the Local Assessment Committee (LAC) will include a representative from the communir-f adjoining the jurlsdiction in which L'1e facility is proposed whe..ever the .djoining community may be adversely affected by the proposal in question. THE FAOLlTY SITING PROCESS The siting p,ocess oulined in t.'1is Chapter is a guide for local land use decision;. It defines the conditions under which it is .ppropnale 10 permit a new or expanded off-site hazardous waste management facility. The"locaJ land use authority" referred to in this Chapter is the city council if the facility is proposed to.be located within a city or the Board of Supervisors if the '. •••• • <.

The initial design and development of hazardous waste facilities is accomplished by privafe developers ... who own and operate the facilities. Government's role will focus on overall planning for these facilities, as well as on the evaluation and the issua"c<> 0( land use permits for proposed facilities. AB 2946 requires certain development review procedures to be used by the local land use authority for , proposed hazardous waste facilities. The required procedures (negotiations between community and developer, consistency Mth jurisdictional plans, environmental assessment, and risk assessmer.t) are desdbcd below. Negotiations Between Community and Developer Section 25199 of the Health and Safety Code specifj.,. the local approval process for the siting of a hazardous waste management facility. One purpose of the permit pr<>eess is to provide an opportunity for negotiations betv.'een the local community and the facility deyeJoper. At least 90 days before applyir,g for a land use permit, the deVeloper must notify the California State Office of Permit Assistance (OP A) and the local land use authority of its intention to apply for a permit (Notice of Intent). This step triggers a public hearing conducted by OPA in the community where the facility 8-5 c·· .. ··,""'_· , • ,­-- I , t l I I is proposed to infonn the public about t..'1e project's nature, f!..1!1ction and scope. Once the applicant files a Notice of Intent (NO!) vdtJ. OPA, OPA notifies the local land use jur'.sdiction. The jurisdiction then has 90 days to appoint a Local Assessment Committe'! (LAC) consisting of seven .. members (three representatives from the commur.ity-at-large, tv.·o representatives of environmen!a1 or public interest groups and two representatives of affected businesses and ind!1sfries) to negotiate with the developer on thE: conditions for projecf approval. The ]oc.a~ iand use jurisdiction sends th~ applicant Initial Srudy materia1s and a risk assessment checklist At the time of application for a local Land Use Permit, the applicant must submit the completed initial study and risk assessment checklist for review by Ihe local land use agency in ecns"ltatiDn with the LAC. Tne beal staff will then detennine wnethe.r or not the applicant needs to prepare a ri!;k assessment and/or an EIR.. If, based on analysis of the completed risk assessment c\",ecklist, local staff determine that a risk assessment must be completed ... the risk assessment shall be consistent with the risle: assessm€nt requirements of the appropriate permitting agendes (e.g., BAAQMD and DHS). Once the develop<!r has filed a complete application for a land use permlt, OPA ' convenes another rr.eeting in the affected community. At n .. js meeting.. the State and local permitting 'gencies, the dev<loper, the LAC and the pubEc identify the issues of cor.cern to th~ agencies and the public. Subsequently, the developer and the LAC negDtiate the terms of project approval .c"'"plable to bet.'> the commmlity and the facility developer. If the LAC .nd developer cannot agree, a medi.cor may be provided by OPA. The LAC advises the city or Cour.ty of the conditions for project approval agreed upon by th LAC and the developer. While these conditions are not binding on the loa! decision making process, this advice should be seriously considered by the locall.nd use authority in its decision on the land use application. Appendix vm -B provides a complete step-by-step discussion of the local approval process for siting hazardous waste management facilities. 8-6 L , ~, --.:. -. .. ;. ~,::.~ ~:~':. '-:~! .- - Consistency with Jw.isdictional Plans In order for the local lmd use authority to approve the I:md use permit, it must fInd that th~ project is ronsistent with the pennitt:ing jurisdictions' ~neral Pla .. i' and zoning in effect .t \f,e time of application ane with the CHWMP. The siting map deye!oped for the Plan delinea~es ger..eral areas U,at appear to meet the siting criteria and appear to be consist"".t with the General Plan. COn'.pliance ,,~th the CHWMP siting criteria is • necessary condition for project approval. Should "1 applicant desire to site a !adlity in an area not cunently identified on tl'1e siting map as an area that appears to meet the siting aiteria for hazardous waste management faciHties, tr~ applicant may seel< • General Plan amendment through the local jurisdiction. Upon revision to the local General Plan, the subject change must be incorporated into the siting map 01 the CHVI'MP. The resulting change to the CHVI'MP must be . approved by a majority of the cities with a majority of the population ""thin the incorporated portion of the County, by the Board of SUF,ervisors, and £mally by DHS. Environmental Impact Report The proponent of a hazardous waste management facility will be required to comply with the California Environmental Quality Act (CEQA) in order to fully inform the public and government decision-makers regarding the environmenta1 consequences of the project ... alte!'Tlatives to the projt'ct, 3l'td mitigation me2~ures that may be required for project approval (note: in ge.neraJ~ mitigation measures are not permitted for residuals repositories due to the potential risks associated v.":lth these facilities). CEQA compliance is a mandatory condition for project approval. After an applicant files a NOr Mth OPA, they must begin preparing an initial study, wr-ich mur.t be submitted to the local land use judsdiction upon filing for a local Land Use Permit The local jurisdiction ",,·m then determine whether an environmental Irr.pact Report (ElR) is required. 8-7 .­"--- - Risk Assessment A multi-media risk assessment (air. surface waeer,l groundwater, soil, sediment: and biota) shall be conducted for incluslon in an EIR if U1e local jurisdktion determines that a risk assessment is required based on local staff's analysts of the completed risk assesSIMI\\ checl<lisl in consultatier, wit." \he LAC. The applicant begins completing \he checklist after filing an NOI with OPA. It must be completed when the applicant files for a local Land Use Permit. The purpose of \he checklist is to dete=ine a r,ew or expanded facility's potential for rel~ase of hazardous chemicals to \he air, surf.ce wafer,l groundwater,l soil, :>ediment, and biota (mclndiIlg estimates of Ute types and quantities of chemicals routinely used and petentian)" ene-lime accidental spills); the probability that a release would impact human, animal, and plant populations (induding prmomity \0 vulner.ble po;>~lation5, climatologic ar,d hydrogeologic factors that would infl.uen<:e transport); and the risks associated with such an impact. H a risk assessment is dee:med necessary. it should consider the potential for atddental (i.e.,I sudden) and cumula.tive health 31ld emrirorunental impacts resulting from the proposed fadlity. SmNG MAP AND CRITERIA Table p...l identifies the siting factors and criteria for residuals repositories and oili£!r hazardous waste managen".ent facilities. The siting criteria for residuals repositories are more stringent than for other hazardous waste management facilities because residuals reposHories may present il greater potential risk fo the community and environment. Evaluation of the results of individual risk assessments for fadlities which are not residuals repositories may justify Ihe application of more stringent criteria for these facilities based on the physical and chemical characteristics of the specific types of wastes that will be handled as well as the fadJity design. AB 2948 requires .that counties which include siting criteria in thett plans must also identify g£neral areas which have not been eliminated after a.pplication oE the siting 8-8 L 1 I I I '-"~ _I , 1 j 0> to - . - Table 8-1: Hazardous Waste Facility Siting Criteria Siting Fador Prolcctjgn or thf Residents or ShC" Clan OU,ID.ll Pro4ection of Prodm.ue and Immobile Populatioru Protcctioo of Public Facilities Silincr ('rite-ria A minimum huffer zone or l,OCO feet !hc::J1d be: provided bel .... , th< property booml"')' of .. y residuaI! reposilory IUld I!n existing rx pl.annr-.d J"e$j. clence or immobile ro9U1aIJon.

Before siting a facility in one of these <and!date 'S.reas~ however, further study would be: required to determine wbether that specific site would be an appropriate location for the proposed type and size of facllity. The facility siting map included in this reper: shows ge.neral areas for potentially siting hazard0US waste management fadlities in Santa Dan: COu..T1~y. The map was developed by overlaying those siting criteria for which maps '-"'ere avatlable on an ir:.dustriaI zoning map for each of the jurisdictions and identlfying areas where these constraints exist. Hgures S.1 through 8-4 (dam and levee failure inundation ,ueas; earthquake faults; areas of liquefaction; a."1d areas of 15 percent or greater slope) are some of the overlay maps used to deveiop the siting map. The siting map identm€s genera! areas l"lhich are consistent with fhe CH'YV?v1P's goals and policies~ but does not identify specific facility site locations. General ~eas for residuals repositories were not identified en the facility siting map due to the a't>sence of areas having a soil permeability of less than 1(}-7 centimeters per second (em/sec). However, this does not predude the possibility that such an ~rea may exist within the County. The siting map is in"":ended to assi:50t both a facility developer and the ger.era1 public to plan for the actua1 siting process, but in no ..... ,ray substitutes for the extensive s{te-syecifk effort req\Ji:red for any faolity deyelop~enL The developer wi}} have to evaluate each criterion at a site-spKific !evel '1:0 assess the potential impacts of a proposed facility on the F'.lbtk heal&. and safety and on the environment.

CONCLUSION 'Ibrough its adoption of the Hazardous Waste Management Hierarchy, the Ccw-.ly strongly supports the reduction in hazardous waste generation at the source of lI'.a.nufacture or chemical processes as the most desirable option to manage ltazardous waste. It is recogttized that the implementation of the Hierarchy may result in significant cP.anges roth in the way hazardous wastes are generated and in the way they are managed. Consistent with the objective of AS 2948, that safe, effective ... and economic facilities which pcolel't publk health and the environment are available when needed, the siting criteria for this CH1NMP shal! be used as standards for siting hazardous waste management facilities that are needed to serve the hazardous waste management needs in Santa Clara County. 8-21 I , , ·._,"::' -: ~:-' ::':~:-" --'.,.--,:G~~~l;r:lllfl' •.
