Findings of Fact

a b EIR No 359 Finding EIR No 359 did not identify any impacts to landfill capacity or due toconflicts with federal state and local statutes and regulations related to solid wastes

SMP 143R2 Finding No Substantial Change from Previous Analysis The Project would notchange the amount of solid waste generated by the mining operation under existing conditions or theconditions assumed in EIR No 359 The proposed Project does not involve the construction of anynew homes and would not increase the number of employees permitted at the site However theproposed Project would extend the expiration date of the existing permits from December 31 2025 toDecember 31 2075 As a result the Project would result in an increased demand for landfill capacityassociated with site worker refuse However with operation of an IDEFO the Project also wouldresult in the diversion of a substantial amount of waste from area landfills thereby offsetting much ofthe increased demand for solid waste capacity that would occur under the Project Although existinglandfills have the capacity to handle solid waste generated by the site under existing conditions manyarea landfills would reach capacity prior to expiration of the Projects permits in 2075 Therefore theproposed Project may ultimately contribute incrementally to the need for a new or expanded landfillfacility However as it cannot be determined at this time whether new or expanded landfills would berequired nor is it possible to identify the location of any such new or expanded landfills any analysisof impacts associated with such landfill expansion or construction would be speculative CEQAGuidelines 15145 Moreover solid waste generated by the Project would only result from siteworkers and operations at the existing office complex and would not comprise a large amount ofrefuse Furthermore there is no evidence that solid waste generated by the Project would exceed thecapacity of any current or planned landfills Accordingly the Projects direct and cumulative impactsto landfill capacity are evaluated as less than significant Additionally there would be no new conflictwith any federal state or local statutes or regulations related to solid waste as a result of theproposed Project Therefore implementation of the proposed Project would not result in any newimpacts or increase the severity of a previously identified significant impact as analyzed in EIR No359

Findings of Fact

SMP 143R2 Finding No Substantial Change from Previous Analysis In compliance with CEQAGuidelines 15130 et seq this section includes a discussion of the potential cumulative impacts ofthe proposed Project As defined by CEQA 15355

Cumulative impacts refer to two or more individual effects which when considered together areconsiderable or which compound or increase other environmental impacts

a The individual effects may be changes resulting from a single project or a number ofseparate projects

b The cumulative impact from several projects is the change in the environment which resultsfrom the incremental impact of the project when added to other closely related past presentand reasonably foreseeable probable future projects Cumulative impacts can result fromindividually minor but collectively significant projects taking place over a period of time

Impact Anal sis

If the cumulative impact is significant the Projectsincremental effect is analyzed to determine if itscontribution to the overall cumulative effect is cumulatively considerable A significant cumulativeimpact does not necessarily mean that the Project related contribution to that impact is alsosignificant Instead under CEQA a project related contribution to a significant cumulative impact isonly significant if the contribution is cumulatively considerable which as defined by CEQAGuidelines 15064h1means that the incremental effects of an individual project are significantwhen viewed in connection with the effects of past projects the effects of other current projects andthe effects of probable future projects

The discussion of cumulative impacts must reflect the severity of the impacts and the likelihood oftheir occurrence however the discussion need not be as detailed as the discussion of environmentalimpacts attributable to the Project alone Further the discussion is guided by the standards ofpracticality and reasonableness

Cumulative Impact Analysis

Aesthetics

Scenic HighwaysAs indicated in the analysis and discussion under Threshold 1a the Project site is locatedapproximately 072 mile southwest of Interstate 15 115 which is identified as a State EligibleScenic Highway Riv County 2003a Figure C9 However due to intervening vegetationtopography and existing development within the Sycamore Creek Specific Plan areas proposed fordisturbance or future reclamation efforts are not prominently visible from 115 As such the proposedProject would not result in changes in the existing environment which would have a substantial effectupon a scenic highway corridor and impacts would be less than significant on a direct and cumulativebasis

Scenic Resources

As discussed under the analysis of Threshold 1b the Project site is partially visible from residenceslocated east of the site The Joyce Deleo Regional Park sits above the Project site to the eastExisting and proposed berms and vegetation located east of the SMP 143R2 site act to reducevisibility of the site from the east Adjacent mining operations border the Project site to the north andthe northwest and the Cleveland National Forest borders the property to the south and the westtherefore visual buffering to the south and west is unnecessary because public access to these areasis limited As indicated in the Visual Simulation Analysis Appendix H reclamation of the Project sitewould remediate all deleterious visual effects associated with the site under both existing andproposed conditions As such the proposed Project would not result in the creation of anaesthetically offensive site open to public view Therefore impacts would be less than significant on adirect and cumulative basis

Mt Palomar ObservatoryAs discussed under the analysis of Threshold 2 the Project site is located approximately 4372 milesfrom the Mt Palomar Observatory The proposed Project would be required to comply with theCounty Light Pollution Standard Ord No 655 which is also applicable to the sitescurrent miningoperations and to surrounding mining operations Additionally changes to the existing miningoperations as proposed by the Project would not generate new sources of excessive light pollutionand lighting would not increase beyond what occurs under existing conditions Cumulative

developments similarly would be required to comply with Ord No 655 to ensure that they would not

Other LightingAs discussed under the analysis of Threshold 3 the proposed Project would not introduce any newsources of lighting beyond what was previously disclosed in EIR No 359 In addition the Project isrequired to operate in conformance with the County Light Pollution Standard Ord No 655Accordingly the proposed Project would not create a new source of substantial light or glare whichwould adversely affect day or nighttime views in the area nor would the Project expose residentialproperty to unacceptable light levels Cumulative developments similarly would be required to complywith Ord No 655 to ensure that they would not create a new source of light or glare or expose nearbyresidences to unacceptable Tight levels Therefore the proposed Project has no potential to result incumulatively adverse impacts to light or glare and a cumulative impact would not occur

Agriculture Forest Resources

Important FarmlandAs discussed under the analysis of Threshold 4athe proposed Project would not convert any PrimeFarmland Unique Farmland or Farmland of Statewide Importance Farmland to non agriculturaluses There are no components of the proposed Project that would result in an increase in impacts toImportant Farmlands beyond what was previously evaluated as part of the EIR No 359 Thus theProject has no potential to directly or cumulatively impact any Farmland types within the Project area

Conflicts with Agricultural Zoning and Williamson Act ContractsAs discussed under the analysis of Threshold 4b4c and 4d the Project site is not subject to anyWilliamson Act contracts and is not located within a Riverside County Agricultural Preserve SMP

143R1 and SMP 150R1 are currently zoned for Mineral Resources and Related Manufacturing MRA and SMP 182 is zoned for Natural Assets NA Although both of these zoning designationsallow for agricultural production they also allow for mining and mining related activities with approvalof a surface mining permit according to Ordinance No 555 Cumulative developments similarly wouldbe required to comply with Ord No 555 Surrounding zoning currently includes M RA to the northSP Zone and RR to the east RR to the south and RR and RA10 to the west Of these zoningdesignations only the R A10 zone comprises an agricultural zoning designation However sincemining uses are already permitted on site the proposed Project would not cause new development ofnon agricultural uses within 300 feet of agriculturally zoned property As such the proposed Projectwould not result in changes in the existing environment which due to their location or nature couldresult in conversion of Farmland to non agricultural use Accordingly the Project would not conflictwith existing agricultural zoning agricultural use or with land subject to a Williamson Act contract orland within a Riverside County Agricultural Preserve cause development of non agricultural useswithin 300 feet of agriculturally zoned property or result in the conversion of Farmland to nonagricultural use Therefore the Project has no potential to result in directly or cumulativelyconsiderable impacts

Forest Land Timberland and Timberland ProductionThere are no lands in the Project vicinity that are zoned for forest land or timberland and there are notimberlands zoned for Timberland Production Accordingly no impact to forest land would occur as aresult of the proposed Project or any cumulative development As such cumulative impacts to forestland timberland or timberland zoned Timberland Production would not occur

Conversion of Forest Land to Non Forest Use

The proposed Project and cumulative developments would not result in the loss of forest land orconversion of forest land to non forest use as there are no forest lands within the Project vicinityAccordingly cumulative impacts have no potential to occur

Air Quality

Conflicts with or Obstruction of Implementation of Applicable Air Quality PlanAs indicated in the discussion and analysis of Threshold 6a the proposed Project represents thecontinuation of an existing mining operation which is in conformance with the Riverside CountyGeneral Plan land use and zoning designations Since the Project sites land use and zoningdesignations are consistent with the General Plan upon which the 2012 South Coast Air QualityManagement Plan SCAQMP was based the Project would therefore conform to the planningassumptions included in the 2012 SCAQMP As such the proposed Project would not conflict with orobstruct implementation of the 2012 SCAQMP Because the proposed Project would not conflict withthe SCAQMP the Project has no potential to cumulatively contribute to impacts due to conflicts withthe SCAQMP accordingly cumulative impacts would be less than significant

Air Quality Standard Violations and Contributions to Existing Air Quality ViolationsAs indicated in the discussion and analysis of Threshold 6b the Project does not propose anychanges in the amount of material annually mined on site or any changes in the operationalequipment or vehicles used on site EIR No 359 identified no conflict with the relevant policies of theRiverside County General Plans Air Quality Element which were designed to implement the policiesand control measures of the 1989 Air Quality Management Plan There are no components of theproposed Project that would result in new or more severe air quality emissions as compared to whatwas evaluated and disclosed by EIR No 359 because daily and annual operations and tonnage limitswould not increase under the proposed Project Furthermore since certification of EIR No 359 in1991 new federal and state air quality standards have reduced emissions associated with motorvehicles including construction equipment that would be operated under the proposed Project thusconstruction equipment that would be utilized under the proposed Project would yield a net reductionin criteria air pollutants as compared to what was evaluated and disclosed in EIR No 359 Thereforeall air quality effects associated with the proposed Project would be less than or equal to those thatwere analyzed and disclosed in EIR No 359 As such the Project would not violate any air qualitystandards or contribute to existing air quality violations Because the proposed Project would notviolate any air quality standards or contribute to existing air quality violations the Project has nopotential to result in cumulatively contribute to impacts due to conflicts with air quality standardsaccordingly cumulative impacts would be less than significant

Cumulatively Considerable Net Increase of Criteria Pollutants for which the Region is Non AttainmentThe proposed Project is a continuation of an existing mining operation As explained in Section 323the Project does not propose any changes in the amount of material mined on site nor does itpropose to increase the number of vehicle trips or increase the number of onsite equipmentassociated with the existing mining operation As such the emissions from the proposed miningoperation are already accounted for in the baseline air quality conditions within the Projects vicinityIn addition future mining operations under SMP 143R2 would be required to comply with morestringent state and federal emission control standards listed under the analysis of Threshold 6cabove Therefore taking into account the stringent air quality requirements presented in Threshold6c and the fact that the Project does not propose any increase in the intensity of the existing miningoperation ie no increased equipment or change to annual tonnage limit the proposed extension of

Exposure of Sensitive Receptors to Substantial Pollutant ConcentrationsAs indicated in the discussion and analysis of Threshold 6d EIR No 359 concluded there were nosensitive receptors in the local area at the time EIR 359 was certified However EIR No 325 whichwas prepared in support of the Sycamore Creek Specific Plan and was certified by the County in1994 included an evaluation of impacts to residents within the Sycamore Creek community locatedadjacent and to the east of the Project site from the ongoing mining operations To mitigate thepotential adverse effect the Sycamore Creek Specific Plan SP 256 required that specializedlandscape buffers be installed and maintained along the property boundary with adjacent miningoperations Therefore any potential impacts to sensitive receptors have previously been mitigated forby design measures incorporated into the Sycamore Creek Specific Plan as documented in EIR No325 Accordingly impacts to nearby sensitive receptors would be less than significant Therefore theproposed Project would result in lessthan significant cumulative impacts due to the exposure ofsensitive receptors to substantial pollutant concentrations

Construction of a Sensitive ReceptorMining related land uses are not sensitive receptors Thus the proposed Project would not involvethe construction of a sensitive receptor located within one 1 mile of an existing substantial pointsource emitter As such cumulative impacts due to the construction of a sensitive receptor would notoccur

Odors

As discussed in the analysis under Threshold 6fmining operations are not typically associated withthe emission of objectionable odors Since the Project does not propose any changes in equipmentor vehicular use and there is no historical record of objectionable odor complaints it is reasonable toconclude that the proposed Project would not create objectionable odors affecting a substantialnumber of people In addition Project generated refuse would be disposed of by a licensed municipalwaste hauler on a weekly basis Accordingly odors generated during operation of the Project wouldbe less than significant on a cumulative basis

Biological Resources

Conflicts with Local Regional or State Conservation PlansAs discussed under the analysis of 7a the Western Riverside County Multiple Species HabitatConservation Plan MSHCP is the applicable habitat conservation planning program for WesternRiverside County As indicted on Figure EA1 MSHCP Overlay Map the Project site is not within anMSHCP criteria cell Although habitat conservation is not required on the Project site by the MSHCPall projects must demonstrate compliance with applicable MSHCP requirements pursuant to thefollowing sections of the MSHCP Section 612 Protection of Species Associated with

RiparianRiverine Areas and Vernal Pools Section 613 Protection of Narrow Endemic PlantSpecies Section 614Guidelines Pertaining to the UrbanWildland Interface and Section 632Additional Survey Needs and Procedures As indicated under Threshold 7a the Project fullycomplies with all applicable provisions of the MSHCP The proposed Project would not conflict withthe provisions of an adopted Habitat Conservation Plan Natural Conservation Community Plan orother approved local regional or state conservation plan Other cumulative developments would

Effects on Endangered Threatened Candidate Sensitive or Special Status SpeciesAs discussed under the analysis of 7b and 7c no NEPSSA CASSA or other sensitive plantspecies were observed within the study area Alden 2014 p 5 In addition according to theProjectsbiologist Alden Environmental Inc no sensitive animal species were observed on siteAlden 2014 p 5 Furthermore as shown on Figure EA2 mining activities would largely becontained to the existing active mining area which is already disturbed As such the Project has nopotential to result in cumulatively significant effects to sensitive plant or animal species Thereforeimpacts to endangered threatened candidate sensitive or special status plant and animal specieswould be less than significant on a cumulative basis

Wildlife Corridors and Nursery SitesAs discussed under the analysis of 7d the Project site is not located within an area identified as anexisting or proposed core or linkage for wildlife movement by the MSHCP Furthermore MitigationMeasure 493 has been revised to ensure that vegetation clearing activities would not impactmigratory birds during the nesting season Other cumulative developments would likewise berequired to implement measures to avoid impacts to nesting birds As such impacts to wildlifemovement and nursery sites would be less than cumulatively significant

Riparian Habitat and Sensitive Natural CommunitiesAs indicated in the analysis of Threshold 7e 2384 acres of the Project site are already disturbed ordeveloped In addition as indicated on Figure 3 2 SMP 143R2 would decrease the existing mininglimits on site by approximately 41 acres This reduction in mining limits would reduce the effects onthe vegetation communities listed in the analysis of Threshold 7e As such the proposed Projectwould result in a lessthan significant cumulative impact to riparian habitat and other sensitive naturalcommunities

Wetlands

Two wetland riparian vegetation communities occur within the study area southern sycamorewoodland and alluvial fan scrub Both of these drainages have been cut off by the previouslyapproved and permitted mine activities and as such are no longer connected to downstream waterbodies As designed the proposed mining limits would not impact either of these drainages therebyavoiding the need for agency permits As such the Project would result in lessthan significantcumulative impacts to wetlands

Local Policies

The only local policyordinance protecting biological resources within the Project area is the In theRiverside County Oak Tree Management Guidelines which requires surveys of individual trees andthe minimization andor avoidance of oak trees where feasible In order to demonstrate compliancewith the CountysOak Tree Management Guidelines a site specific Oak Tree Survey was conductedfor the Project site The proposed Project would impact 19 individual coast live oak trees treenumbers 1 19 in Table EA1 However Mitigation Measure493hhas been imposed on the Projectto ensure that impacts to oak trees would be mitigated in accordance with County requirements andimpacts would therefore be less than significant Other cumulative developments would similarly berequired to demonstrate compliance with the Oak Tree Management Guidelines As such withincorporation of Mitigation Measure493himpacts to oak trees would be less than cumulativelysignificant

Cultural Resources

Historical Sites and Resources

As discussed above in Threshold 8a and 8b the Project site has been disturbed for over 35 yearsand as such there is a very low likelihood that any historic sites or historical resources as defined inCalifornia Code of Regulations Section 150635 would be found onsite Mitigation measuresidentified in EIR No 359 would continue to apply to the proposed Project and have been incorporatedinto the Projects conditions of approval The proposed Project would not result in any adverseimpacts to any historic sites or historical resources assuming implementation of the requiredmitigation Other cumulative developments would be required to incorporate measures asappropriate to address the potential for impacts to historical sites and resources Accordinglyimpacts to historic resources or sites would be less than significant on a cumulative basis

Archaeological Sites and ResourcesThe Project site has been disturbed for over 35 years and no archaeological resources havepreviously been identified in the course of mining activities Grading also was previously conductedalong Maitri Road the eastwest oriented access roadway located at the northern boundary of theProject site indicating there is no potential for uncovering archaeological resources in this area In

addition according to the Riverside County General Plan EIR the Project site is not identified withinan area containing sensitive archaeological resources Riv County 2003a Figure 471 Mitigationmeasures as modified herein from EIR No 359 would continue to apply to the proposed Project andhave been incorporated into the Projectsconditions of approval The proposed Project would notresult in any adverse impacts to any archaeological sites or resources assuming implementation ofthe required mitigation Other cumulative developments would be required to incorporate measuresas appropriate to address the potential for impacts to archaeological sites and resourcesAccordingly impacts to archaeological resources or sites would be less than significant on acumulative basis

Human Remains

As indicated under the analysis of Threshold 8c under existing conditions and consistent with theconditions that existed at the time the EIR No 359 was certified the Project site is fully disturbed dueto on going mining operations As such the potential for the discovery of human remains is highlyunlikely However if human remains were encountered on site or on the site of any cumulativedevelopments mandatory compliance with California Health and Safety Code Section 70505andPublic Resources Code Section 509798 included as part of Mitigation Measure 4103bwouldensure that impacts remain below a level of significance Compliance with applicable Stateregulations and the mitigation measures from EIR No 359 would ensure that impacts associated withthe discovery of human remains would be less than significant on both a direct and cumulative basis

Religious or Sacred UsesBecause the Project site has been mined for over 35 years there is no potential for religious or sacreduses to occur onsite As such implementation of the proposed Project would not result in anyadverse impacts to any religious or sacred uses on a direct or cumulative basis

Paleontological ResourcesThe Project site has been mined for over 35 years and the potential for new paleontologicalresources sites or geological features to be uncovered on site is highly remote Portions of the siteare nonetheless categorized by Riverside County as areas of high paleontological sensitivity Riv

Geology and Soils

Due to the site specific nature of potential impacts associated with geology and soils there is nopotential for the Project to contribute to cumulatively significant impacts associated with the sitesgeology and soil conditions All development in the County is required to comply with the CaliforniaBuilding Standards Code and follow the recommendations of project specific geotechnical reportsadherence to which would preclude cumulatively significant impacts

Greenhouse Gas Emissions

As indicated in the discussion and analysis of Greenhouse Gas Emissions under Issue 21 Projectrelated GHG emissions would be below the County and SCAQMD screening threshold of 10000MTCO Additionally the Project would not conflict with any applicable plan policy or regulationadopted for the purpose of reducing greenhouse gas emissions Other cumulative developmentswould similarly be required to demonstrate consistency with applicable plans policies or regulationsand must also demonstrate that emissions would be below the County and SCAQMD thresholds ofsignificance Accordingly Project impacts due to GHG emissions would be less than significant on acumulative basis

Hazards and Hazardous Materials

Transport Use and Disposal of Hazardous MaterialsAs part of the proposed Project explosives used for blasting would continue to be transported to thesite as needed In addition oils and fuels for mining related equipment would be shipped to theProject site on an asneeded basis Equipment is fueled from two above ground storage tankslocated on the property that are housed in a structure with secondary containment measures which isdesigned to reduce the potential for spills Waste oil is hauled offsite by a licensed hazardous wastetransporter for disposal in accordance with local state and federal regulations When spent oil filterand antifreeze drums are full or reach the maximum 90day accumulation period they are closed andtransferred onto trucks and hauled offsite by a licensed hazardous waste transporter Furthermorethe mining operation is inspected on an annual basis by the County of Riverside Department ofEnvironmental Health DEH for any hazardous materials problems No prior violations have beenidentified by the DEH In addition Mitigation Measures identified in EIR No 359 would continue toapply to the proposed Project Therefore the routine transport of aggregate materials would notresult in any significant hazards to the public or the environment and impacts would be less thansignificant on a cumulative basis

Upset and Accident ConditionsAs concluded in the discussion and analysis under Threshold 22bthe Project would not create asignificant hazard to the public or the environment through the release of hazardous materials Dieselfuel is stored in two 2000 gallon above ground tanks and a concrete pad surrounds the fueling areaThe tanks sit within a secondary containment area and a hose and nozzle are used to pump fuel fromthe tanker truck into the storage tank Each fuel pump is equipped with an automatic shutoff valveIn addition oil grease solvents oxygen nitrogen and acetylene are stored inside the maintenance

Emergency Evacuation and Response PlansThe Project site is not located within any adopted emergency response plans or emergencyevacuation plans Furthermore there are no residential structures or businesses that would requireaccess through the area during an emergency as the area is accessed by a private roadway Assuch the Project would not impair implementation of or physically interfere with an adoptedemergency response plan or an emergency evacuation plan and impacts would be less thansignificant Accordingly impacts would be less than significant on a cumulative basis

Hazardous Materials Impacts to SchoolsAs discussed under the analysis of Threshold 22d the existing SMP 143R1 mining site is locatedapproximately 03 mile southwest of Todd Elementary School In addition the Project would involveaggregate mining activities which are not associated with the emission or storage of acutelyhazardous materials substances or waste Accordingly impacts due to the storage or use ofhazardous materials within one quarter mile of an existing or proposed school would be less thansignificant on a cumulative basis

Hazardous Materials Site

The Project site is not included on any list of hazardous materials sites compiled pursuant toGovernment Code Section 659625 Accordingly no impact would occur on a direct or cumulativebasis

AirportsThe Project site is not located within any Airport Master Plans airport influence areas or airportcompatibility zones and would not require review by the Airport Land Use Commission In additionthe Project site is not located within the vicinity of any public or private airports or heliports GoogleEarth 2013 As such the proposed Project would not result in any cumulative impacts to airportfacilities

Wildfire Hazards

As noted under the analysis of Threshold 24a the Project site is located within an area that ismapped as having a high susceptibility to wildland fire hazards Riv County 2014a However theProject does not propose to construct any structures on the property that could expose people to asignificant risk of loss injury or death associated with wildland fires Moreover the Project site andareas to the north and northwest are fully disturbed and contain very little vegetation under existingconditions that could be susceptible to wildfire Existing residential areas to the northeast areprotected by fuel management zones and no activities proposed by the Project would increase therisk of wildfire to this area Furthermore following reclamation the site would be planted with plantspecies that are not considered to pose a threat of wildland fire hazards As such the proposed

Project would not expose people or structures to a significant risk of loss injury or death involvingwildland fires Accordingly impacts would be less than significant on a cumulative basis

Hydrology and Water Quality

Alteration of Drainage PatternsAs concluded under the analysis of Threshold 25aall drainage from the Mayhew Creek and othertributaries located to the southwest of the Project site would be retained onsite within the excavatedpits and would not discharge to downstream conveyances receiving waters In addition the proposedProject would not impact the existing drainage feature located along the eastern perimeter of theProject site The proposed Project would result in changes to the sites drainage patterns by allowingfor mining in the setbacks between the existing mining pits onsite Additionally as part of theproposed Project the 30foot concrete down drain structure currently designed to convey runoff downthe slope of SMP 139R1 would be relocated to connect the existing earthen channel near thesouthern Project limits to a proposed retention basin within the Project site However such changeswould not alter the course of a stream or river in a manner that would result in substantial erosion orsiltation on or offsite because all drainage would continue to be retained onsite In additionbecause all runoff would be retained on the property and allowed to infiltrate into the ground theProject would not result in any increase in the amount of runoff discharged from the site Moreoverthe Project shall be required to comply with the best management practices BMPs identified in thesite specific WQMP which are similar to those that occur under existing conditions which wouldfurther preclude the potential for increased erosion Other cumulative developments would similarlybe required to demonstrate compliance with site specific BMPs Therefore cumulativelyconsiderable impacts would be less than significant

Water Quality StandardsWaste Discharge RequirementsAs discussed in the analysis of Threshold 25b pursuant to California Water Code Section 13269the California Regional Water Quality Control Board RWQCB Board adopted Resolution No R820130015 waiving waste discharge requirements for specific types of discharges including theproposed IDEFO and mining activities In addition on May 13 2014 the California Regional WaterQuality Control Board RWQCB Santa Ana Region issued a waiver of waste dischargerequirements for the proposed Project The waiver indicates that operations proposed as part of theProject including aggregate mining activities and IDEFO operations are waived from the

requirements of Section 13263 of the California Water Code subject to certain conditions listed under25b In order to ensure compliance with the above described requirements Mitigation Measure4103c has been identified to ensure compliance with the waiver of waste discharge requirementsOther cumulative developments would similarly be required to demonstrate compliance with therequirements of Section 13263 of the California Water Code Therefore cumulatively considerableimpacts would be less than significant

Groundwater Supplies and RechargeWater used at the Project site is obtained by one of the EVMWD wells in the Temescal Valley Nowells are located on site The proposed Project would not result in a net increase in the amount ofimpervious surfaces onsite and would not result in a net increase in the amount of water used onsiteas compared to existing conditions In no case would water from Mayhew Creek be utilized duringsite operations Accordingly the proposed Project would not substantially deplete groundwatersupplies or interfere substantially with groundwater recharge and there would be no net deficit inaquifer water volumes or groundwater table levels as a result of the Project Therefore direct andcumulative impacts would be less than significant

Impact Analysis

Stormwater Runoff

As indicated under the evaluation of Threshold 25a the proposed Project would retain all runoffwater on the property and would not discharge to downstream conveyances receiving waters withexception of the existing runoff that occurs along the eastern perimeter of the SMP 143R1 site whichwould be retained as part of the Project Because no changes to the rate or amount of runoff alongthe sites eastern perimeter are proposed as part of the Project the Project would have no potential tocreate or contribute runoff water that would exceed the capacity of existing or planned stormwaterdrainage systems or provide substantial additional sources of polluted runoff Moreover the Projectwould be required to comply with the BMPs identified in the WQMP refer to Appendix F which wouldensure that the Project would not result in the creation of substantial amounts of polluted runoffOther cumulative developments would similarly be required to demonstrate compliance with sitespecific BMPs Therefore cumulatively considerable impacts would be less than significant

Flood Hazards

As noted in the discussion of Threshold 25e and 25f the Project does not propose to build housingon site nor does the Project propose to construct any new structures that would impede or redirectflood flows Furthermore according to Riverside County General Plan Figure S9 100 and 500 YearFlood Hazard Zones the Project site is not located in a flood hazard zone In addition the Project siteis not located in a dam failure inundation zone Riv County 2003a Figure S10 As such noimpacts due to flooding would occur on a direct or cumulative basis

Other Effects on Water QualityMandatory compliance with the BMPs specified in the Projects WQMP refer to Appendix F wouldensure that the Project does not result in any other impacts to water quality As such no water qualityimpacts would occur on a direct or cumulative basis

Vectors and Odors

As discussed in the analysis and discussion of Threshold 25dthe existing and planned retentionbasins are designed to allow for infiltration of runoff thereby precluding the potential for vectors iemosquitoes and odors There are no other BMP devices associated with the Project that could resultin significant environmental effects As such the proposed Project would not result in changes toBMPs which could result in significant environmental effects Therefore cumulatively considerableimpacts would be less than significant

Alteration of Drainage Patterns Increased RunoffAs discussed under the analysis of Threshold 26a peak flows from the site would not change underthe proposed Project as all runoff would be detained on site JEBA 2014b p 18 JEBA 2014aAppendix 6 except for existing flows along the eastern perimeter of the site that would remainunchanged by the Project Accordingly the mining and ultimate reclamation of the SMP 143R2 sitewould not substantially alter the existing drainage pattern of the site or area and impacts due toflooding on or offsite would be less than significant on a direct and cumulatively considerable basis

Absorption RatesThe proposed Project would alter areas subject to mining activities by allowing for mining in thesetbacks between the existing mining pits However the Project would decrease the overall miningand disturbance limits on site Proposed mining activities would have no adverse effect on absorptionrates relative to existing conditions as the Project would not result in an increase in impervioussurfaces As indicated under the evaluation of Threshold 25a with exception of the existing

drainage in the eastern portion of the site that would not be affected by the Project the Project wouldretain all runoff water onsite and would not discharge to downstream conveyancesreceiving watersTherefore all rain water falling on the property would continue to percolate into the ground as occursunder existing conditions and there would be no change in the rate or amount of surface runoff Assuch the Project would not result in any changes in absorption rates or the rate and amount ofsurface runoff and impacts would be less than significant on a cumulative basis

FloodingAs discussed under Threshold 26cthe Project would not expose people or structures to a significantrisk of loss injury or death involving flooding According to Riverside County General Plan Figure S9 100 and 500 Year Flood Hazard Zones the Project site is not located in a flood hazard zone Inaddition the Project site is not located in a dam failure inundation zone Riv County 2003a Figure S10 As such no cumulative impacts due to flooding would occur

Surface Water

As indicated under the evaluation of Threshold 25awith exception of the existing drainage in theeastern portion of the site that would not be affected by the Project the Project would retain all runoffwater on the property and would not discharge water to any downstream conveyances receivingwaters The Project site would continue to retain the 100year 24hour runoff volume in an off or onsite retention basin Temporarily ponded water that is retained in the basin would percolaterecharging the groundwater table As such Project implementation would not result in a change inthe amount of surface water in any water body Accordingly impacts due to a change in the amountof surface water would be less than significant on a cumulative basis

Land Use and Planning

Land Use

As indicated under the analysis of Threshold 27a new areas proposed for mining primarily liebetween existing mining pits and already are associated with the existing mining operations No newland uses are proposed on the site following completion of reclamation activities and any new landuses other than mining or open space would require an amendment to the General Plan Land UseElement and Zoning Ordinance There are no conditions associated with the proposed Project thatwould result in a substantial alteration of the present or planned land use of the area As suchimpacts would be less than significant on a cumulative basis

Sphere of InfluenceThe Project site is located in unincorporated Riverside County within the sphere of influence for theCity of Corona The proposed Project is consistent with the zoning and General Plan designationsapplied to the property by Riverside Countyie Open Space Mineral Resources and Mineral

Resources and Related Manufacturing M RA respectively According to Figure 12 of the City ofCorona General Plan the Project site is prezoned for General Industrial land uses which allows formining activities Although the Project site may be annexed by the City of Corona at some point in thefuture the land uses proposed by the Project would not conflict with the Citys proposed General Planland use designation for the site Corona 2004 Accordingly the proposed Project would notadversely affect land use within the City of Corona sphere of influence or unincorporated RiversideCounty Accordingly impacts to land uses within a city sphere of influence or adjacent city boundarywould be less than significant on a cumulative basis

Impact Analysis

Sites Existing or Proposed ZoningThe Project site is zoned by Riverside County for Mineral Resources and Related Manufacturing MRA and Natural Assets NA Riv County 2014a No changes to these zoning designations areproposed as part of the Project The existing zoning designations also are consistent with the sitesRiverside County General Plan designation of Open Space Mineral Resources OS MIN RivCounty 2014a Neither Riverside County nor the property owners of the Project site have plans tochange the existing zoning of the Project site As such the proposed Project would be consistent withthe sites existing zoning and no cumulative impacts would occur

Existing Surrounding ZoningAs discussed under the analysis of Threshold 28b zoning designations surrounding the Project siteinclude the following Rural Residential RR and RuralAgricultural RA10 to the west M RAand Special Plan Zone SP Zone to the north SP Zone and RR to the east and RR to the southRiv County 2014a Mining activities proposed as part of the Project would be consistent with theM RA zoning designation to the north and would not conflict with the RR and RA10 zoningdesignations to the west and south With respect to the Sycamore Creek Specific Plan located to theeast of the Project site adequate buffers and an earthen berm are provided or are planned by theSycamore Creek developer along the western boundary of the Sycamore Creek Specific Plan toensure that land use conflicts would not occur between the existing and proposed residential landuses and proposed mining operations Accordingly the proposed Project would be compatible withexisting surrounding zoning and no impacts would occur on a direct or cumulatively considerablebasis

Existing and Planned Surrounding Land UsesAs discussed under the discussion and analysis of Threshold 28a General Plan land usedesignations surrounding the Project site include the following OSMIN to the north Open SpaceRural OSRUR and Open Space Conservation Habitat OSCH to the east OS CH to the southand Open Space Conservation OSC Estate Density Residential EDR Very Low DensityResidential VLDR and Rural Residential RR to the east Riv County 2014a As indicated

under the analysis of Threshold 28b the proposed Project would not conflict with the existing orplanned land uses within the Project area Accordingly the proposed Project would be compatiblewith existing and planned surrounding land uses and impacts would be less than significant on adirect and cumulative basis

General Plan ConsistencyThe Project site is designated for OS MIN land uses by the County General Plan Riv County2014a Mining operations proposed as part of the Project would be fully consistent with this land usedesignation The proposed Project also would not conflict with any policies of the General Plan or theTemescal Valley Area Plan as the proposed Project is limited to the continuation of an existingcondition recognized by the General Plan As such the proposed Project would be consistent withthe land use designations and policies of the General Plan Accordingly cumulative impacts wouldnot occur

Disrupt or Divide an Established CommunityThe proposed Project would result in the expansion of existing mining operations onsite between theexcavation pits of existing mines Such an expansion would not impact surrounding areas The

proposed Project therefore has no potential to result in the physical division of any establishedcommunities including lowincome or minority communities Accordingly a cumulativelyconsiderable impact would not occur

Mineral Resources

Loss ofMineral Resources

The Project site is comprised of an existing mining operation that has been in operation for over 35years According to the Riverside County General Plan the Project site is located within a MineralResources Zone 2 MRZ2 area pursuant to the Surface Mining and Reclamation Act of 1975SMARA Riv County 2003a Figure OS5 The proposed Project would involve the continuation ofan existing mining operation which would result in the continued commercial extraction andproduction of the propertysmineral resources Therefore the Project would allow continued use ofthe propertysaggregate resources As such the Project would not result in any adverse impacts dueto the loss of availability of a known mineral resource that would be of value to the region or theresidents of the State nor would the Project result in any impacts due to the loss of availability of alocally important mineral resource recovery site delineated on a local general plan specific plan orother land use plan As such the Projects impact would be less than significant on a direct andcumulative basis

Incompatible Land UsesAs discussed under the analysis of Threshold 29c surface mining operations exist to the north andnorthwest of the Project site Google Earth 2013 The mining activities proposed as part of theProject would be inherently compatible with these existing operations As such the proposed Projectwould not be an incompatible land use located adjacent to a State classified or designated area orexisting surface mine Accordingly the Project has no potential to result in or contribute tocumulatively considerable effects associated with incompatible land uses

Mining HazardsAs discussed under the analysis of Threshold 29dthe Project site is accessed by a private roadwayMaitri Road which would be controlled by security guards to prevent people from trespassing intoactive mining areas In addition fencing would be maintained around active mining pits Likewisethe Project site would be sufficiently marked with signage as required under existing conditions Inaddition the Project site would be locked when not in operation or open for sales to preventunauthorized access Site workers would have the potential to be exposed to hazards inherent tomining operations but such hazards would be addressed through mandatory compliance with federalstate and local regulations governing working conditions in mines Moreover mining activities to beundertaken as part of the Project would be no more hazardous to people or property than the miningactivities that occur on the property under existing conditions Accordingly the proposed Projectwould have a less than significant cumulative impact resulting from the exposure of people of propertyto hazards from proposed existing or abandoned quarries or mines

Noise

Airport NoiseThe Project site is not located within an airport land use plan and there are no public or privateairstrips located within two miles of the Project site Google Earth 2013 Riv County 2003a FigureS19 As such the proposed Project would not expose people residing or working in the Project areato excessive noise levels Therefore a cumulatively considerable impact would not occur

Railroad Noise

The Project site is not located near any railroads Additionally no aspect of the proposed Projectinvolves railroad use or rail transport Riv County 2003a Figure C1 Google Earth 2013Accordingly no cumulative railroad related noise impacts would occur

Highway NoiseAs noted in the discussion and analysis of Threshold 32 SMP 143R2 does not propose to increasethe truck traffic to or from the Project site beyond recent levels or the levels evaluated in EIR No 359Therefore because the level of truck traffic would remain consistent with the levels analyzed in EIRNo 359 there would be no increase in the amount of highway noise produced by the ProjectTherefore highway noise effects associated with the proposed Project are within the scope ofanalysis of EIR No 395 which indicated that such noise impacts would be less than cumulativelyconsiderable

Other Noise

The proposed Project involves a mining operation which is not a noise sensitive receptor As suchthere is no potential for the Project to be impacted by other noise generators As such no cumulativeimpacts would occur

Ambient Noise Levels

As concluded under the discussion and analysis of Thresholds 34a and 34b the proposed Projectwould extend the life of an existing mine and allow mining to take place within the setbacks betweenexisting mining pits The Project does not propose any operational changes to the processing plant orits location at this time At some point in the future mining operations may transition to the westernedge of the mining area but this would locate processing activities farther away from residences orother receptors thereby decreasing any ambient noise effects as compared to existing conditionsFurthermore as concluded in EIR No 325 the Sycamore Creek Specific Plan located to thenortheast of the Project site was designed to incorporate a buffer zone between the residences andmining operations which was determined to reduce noise levels below a level of significance On sitemachine use would not increase beyond recent levels or the levels evaluated in EIR No 359Therefore the ambient noise effects from Project related equipment would not increase as a result ofthe Project Mining and blasting operations would continue as part of the proposed Project Howeverthe permitted tonnage would remain capped at an annual rate of 20 mtpy indicating that future miningor blasting activities would be similar to previous efforts As such ambient noise effects from Projectrelated mining or blasting activities would not increase as a result of the Project beyond the levelsevaluated and disclosed by EIR No 359 to be less than significant on both a direct and cumulativebasis In addition the Project would comply with Riverside County Ordinance No 555 the CountysNoise Ordinance and applicable policies within the Riverside County General Plan Accordinglyimpacts due to a substantial increase in ambient noise levels would be less than significant on acumulative basis

Applicable StandardsAs noted in the discussion and analysis of Thresholds 34a and b and consistent with the findings ofEIR No 359 near and longterm operations at the Project site would not generate noise levels inexcess of the standards established in the Riverside County General Plan or the Countys NoiseOrdinance and impacts would be less than significant with implementation of the mitigation measuresidentified in EIR No 359 Project related traffic mining and blasting activities would occur at levelssimilar to those that occur under existing conditions and that were assumed in EIR No 359Furthermore mitigation incorporated into the Sycamore Creek Specific Plan was determined to

reduce noise levels to below a level of significance Accordingly impacts resulting from the exposureof persons to or the generation of noise in excess of standards established in the local general plan ornoise ordinance would be less than significant on a cumulative basis

Groundborne Vibration or Noise Levels

Although the Project proposes to mine the setbacks between the existing mining pits the permittedtonnage would remain capped at an annual rate of 20 mtpy indicating that any future mining orblasting activities would be similar to previous efforts and fully within the scope of analysis of EIR No359 Any impacts to ground borne vibration or ground borne noise levels as a result of on site miningor blasting activities were mitigated to a level below significance by Mitigation Measure 453renumbered herein as Mitigation Measures453athrough453fwhich would continue to apply tothe proposed Project As such and consistent with the conclusion reached by EIR No 359 theProject would not cumulatively contribute to excessive groundborne vibration or groundborne noiselevels and a less than significant impact would occur

Population and Housing

Displacement of Residents or HousingAs discussed under the analysis of Threshold 35a and 35c the Project site does not contain anyhousing under existing conditions Accordingly the proposed Project would have no potential todisplace housing or people necessitating the construction of replacement housing elsewhere As

such the Project has no potential to result in cumulatively considerable effects associated with thedisplacement of people or housing which could necessitate the construction of replacement housingelsewhere

Housing and Population GrowthThresholds 35b 35e and 35f above address the Projectspotential effects on housing demandand population growth The proposed Project involves the continuation of an existing miningoperation and would not result in an increase in the number of people employed onsite The samenumber of people are expected to be employed by the Project as are employed at the site underexisting conditions In addition the Project would not require the extension of any new infrastructureor roads and would not involve the creation of new homes or a new business As such the proposedProject would not create a demand for additional housing and would have no potential to cumulativelyexceed official regional or local population projections In addition the Project would also not inducesubstantial population growth either directly or indirectly Accordingly implementation of the proposedProject would result in a lessthan significant cumulative impacts due to a demand for additionalhousing or substantial population growth

County Redevelopment Project AreaAs discussed under Threshold 35d the Project site is not located within or adjacent to any CountyRedevelopment Project Areas As such the Project has no potential to result in cumulativelyconsiderable effects associated with a County Redevelopment Area

Sheriff Services

As discussed under the analysis of Threshold 37 the proposed Project involves the continuation andexpansion of an existing mining operation which is provided law enforcement services under existingconditions by the Riverside SheriffsDepartment The Project does not propose any change in thescope of operations or number of employees hours of operation or truck traffic that would require anexpansion of law enforcement services As such the proposed Project would not result in asubstantial increase in demand for sheriff services as compared to what was evaluated and disclosedin EIR No 359 Accordingly the proposed Project would result in a lessthan cumulativelyconsiderable impact associated with the need for new or expanded fire protection facilities

Schools

As concluded in the analysis and discussion of Threshold 38 the proposed Project does not involvethe construction of any new homes would not affect local demographics and would not increase thepermitted number of employees at the site As such there would be no increase or decrease indemand for school services resulting from Project implementation and no need for physical alterationsto school facilities Therefore impacts to school facilities would be less than cumulativelyconsiderable

Libraries

The proposed Project does not involve the construction of any new homes would not affect localdemographics and would not increase the number of employees permitted at the site As such therewould be no increase or decrease in demand for library services resulting from Project implementationand no need for physical alterations to library facilities As such the proposed Project would notresult in a substantial increase in demand for library facilities as compared to what was evaluated anddisclosed in EIR No 359 Accordingly the proposed Project would result in a lessthan cumulativelyconsiderable impact associated with the need for new or expanded library facilities

Health Services

As discussed under the analysis and discussion of Threshold 40 the proposed Project does notinvolve the construction of any new homes would not affect local demographics and would notincrease the number of employees permitted at the site As such there would be no increase or

Community Service Area Community Parks and Recreation PlanThe proposed Project is not located within a CSA or recreation and park district with a CommunityParks and Recreation Plan and because the Project is limited to the continuation and expansion of anexisting mining operation no Quimby fees would be required for the Project As such the Project hasno potential to result in direct or cumulatively considerable impacts associated with a CSA orCommunity Parks and Recreation Plan

Recreational Trails

As discussed in the analysis and discussion of Threshold 42 two trail segments are planned in theimmediate vicinity of the Project site including a Historic Trail along Temescal Canyon Road and aCommunity Trail located immediately adjacent to the eastern boundary of the Project site RivCounty 2003b Figure 8 However the proposed Project does not abut Temescal Canyon Road andwould not result in any new residents that would generate a demand for recreational trails In

addition the Community Trail planned along the siteseastern boundary is accommodated within theadjacent Sycamore Creek Specific Plan Furthermore no recreational trails are planned as part of theProject Accordingly the proposed Project would not conflict with any designated trail alignmentsand would not result in any significant environmental effects associated with the construction ofrecreational trails As such the Project has no potential to result in direct or cumulativelyconsiderable impacts associated with recreational trails

Transportation and Traffic

Conflicts with Measures of Effectiveness

Under the proposed Project total annual tonnage would remain capped at a maximum of 20 mtpy Inaddition the IDEFO would utilize existing truck trips to deliver fill materials when possible As suchthere would be no increase in traffic from the site with implementation of the Project as compared toexisting conditions or the conditions that were evaluated in EIR No 359 Because EIR No 359

concluded impacts to traffic would be less than significant on both a direct and cumulative basis andbecause the amount of truck traffic from the site would not increase and would be within the scope ofanalysis of EIR No 359 cumulative impacts due to a conflict with an applicable plan ordinance orpolicy establishing a measure of effectiveness for the performance of the circulation system would beless than significant and no new mitigation would be required

Conflicts with Congestion Management PlanAs noted under the discussion of Threshold 43b within the Projectsvicinity only Interstate 15 1 15is identified as a CMP facility Riv County 2011 Exhibit 41A The Project would not increase theamount of truck traffic to or from the site beyond existing conditions or the conditions evaluated in EIRNo 359 because permitted levels would remain capped an annual rate of 20 mtpy In addition theIDEFO would utilize existing truck trips to deliver fill materials when possible potentially resulting in anet decrease in traffic associated with the site Consistent with the conclusion of EIR No 359 theProject would not contribute more than 50 peak hour trips to the 1 15 or any CMP facility Riv County1991 Figure 46 Accordingly the Project has no potential to conflict with the level of service

Impacts to Air Traffic PatternsAlteration of Waterborne Rail and Air TrafficAs indicated in the discussion and analysis if Threshold 43cand 43d the Project site is not locatedwithin close proximity to any public or private airports and is not located within any AirportComprehensive Land Use Plans ACLUP In addition there are no existing waterborne routes in theProject vicinity nor are any railroads located near the Project site Accordingly the proposed Projectwould have no cumulatively considerable impacts on waterborne rail or air traffic

Hazards

The proposed Project represents the continuation of an existing mining operation and would notresult in the introduction of any new incompatible uses to the site that could pose a traffic safetyhazard for surrounding land uses No roadway improvements are planned as part of the ProjectAccordingly the proposed Project would not substantially increase hazards due to a design featurecumulatively significant impacts would not occur

New or Altered Roadway MaintenanceImplementation of the proposed Project would extend the life of the existing mining permit by 50years Since the Project would increase the duration over which Project related traffic would utilizeCounty roadways the Project would over time result in an increased need for the County to maintainroadway facilities in the local area However maintenance of nearby roadway facilities would befunded through taxes generated by the Project and the increased length of demand for roadwayfacility maintenance would not result in the Countys inability to fund other improvements such thatsignificant environmental impacts would result As such the Project would have a lessthansignificant cumulative impact on the need for new or altered maintenance of roads

Construction Circulation

As discussed under the analysis of Threshold 43g since the proposed Project represents thecontinuation of an existing operation and would not involve a construction phase there would be noimpacts to the circulation network associated with construction activities Although portions of MaitriRoad may be relocated as a reasonably foreseeable consequence of the proposed Project MaitriRoad is a private roadway facility and the relocation of this facility would have no adverse impact onthe areas circulation system As such the Project would have no direct or cumulative impacts on theneed for new or altered maintenance of roads

Emergency AccessAs discussed under the analysis of Threshold 43hthe Project site is not identified as an emergencyaccess route under any local or regional plans and roadways serving the Project site do not provideaccess to any other land uses except for adjacent mining sites Accordingly there would be no director cumulatively considerable impact due to inadequate emergency access or due to obstruction ofaccess to nearby uses

Policies Promoting Non Vehicular TransportationThe Riverside County General Plan does not identify the Project site for any public transit facilitiesbikeways or pedestrian facilities In addition there are no components of the proposed Project that

Utility and Service Systems

Water Treatment Facilities

As discussed under the analysis of Threshold 45a the proposed Project would not result in a netincrease in demand for water resources as compared to existing conditions or the conditionsevaluated in EIR No 359 As such the proposed Project would not require or result in theconstruction of new water treatment facilities or expansion of existing facilities the construction ofwhich would cause significant environmental effects Accordingly the Project would have no potentialto result in any cumulatively considerable impacts associated with the construction of new watertreatment facilities

Sufficient Water SuppliesWater to the Project site is provided by the EVMWD Since the proposed Project represents an activemining operation that has been in existence since prior to 2000 when the EVMWD prepared its firstUrban Water Management Plan and since water usage would not increase under the proposedProject the proposed Project is accounted for in the EVMWDsUWMP Since the UWMP concludesthat the EVMWD has sufficient water supplies available to serve all existing land uses within itsservice area and since the Project would not result in an increased demand for water resources itcan therefore be concluded that the EVMWD would have sufficient water supplies available to servethe Project from existing entitlements and resources and no new or expanded entitlements would beneeded Accordingly the Project would have no potential to result in any cumulatively considerableimpacts associated with the need for new or expanded entitlements

Sewer

As discussed under the analysis of Threshold 46a and 46b the proposed Project does not involvethe construction of any new homes and would not increase the number of permitted employees at thesite As such there would be no increase in the sites demand for wastewater treatment facilities orcapacity Furthermore wastewater generated at the site under existing conditions is handled viaportable toilets and no new portable toilets would be required in support of the Project As such theproposed Project would not require the construction of wastewater treatment facilities or result in adetermination that the wastewater treatment provider does not have adequate capacity to serve theprojectsprojected demand Accordingly impacts would be less than significant on a direct andcumulative basis

The Project would not change the amount of solid waste generated by the mining operation ascompared to existing conditions or the conditions evaluated in EIR No 359 The proposed Projectdoes not involve the construction of any new homes and would not increase the number ofemployees permitted at the site However the proposed Project would extend the expiration date ofthe existing permits from December 31 2025 to December 31 2075 As a result the Project wouldresult in an increased demand for landfill capacity Existing landfills have the capacity to handle solidwaste generated by the site under existing conditions but many area landfills would reach capacityprior to expiration of the Projectspermits in 2075 Therefore the proposed Project may ultimatelycumulatively contribute to the need for a new or expanded landfill facility However as it cannot bedetermined at this time whether new or expanded landfills would be required nor is it possible toidentify the location of any such new or expanded landfills any analysis of impacts associated withsuch landfill expansion or construction would be speculative CEQA Guidelines 15145 Moreoversolid waste generated by the Project would only result from site workers and operations at the existingoffice complex and would not comprise a large amount of refuse Furthermore there is no evidencethat solid waste generated by the Project would exceed the capacity of any current or plannedlandfills Additionally there would be no new conflict with any federal state or local statutes orregulations related to solid waste as a result of the proposed Project Accordingly the Projects directand cumulative impacts to landfill capacity are evaluated as less than significant

Utilities

As discussed under the analysis and discussion of Threshold 48a through 48g the proposedProject would involve the continuation of an existing mining operation and would not result in asubstantial increase in daily operational characteristics at the site All utilities needed to serve theproposed Project are currently in place As such the proposed Project would not require the physicalexpansion of utilities including the use of electricity natural gas communications systems stormwater drainage street lighting public facilities including roads or other governmental servicesAccordingly the Projectscumulative impacts to utilities would be less than significant

Energy ConservationThe Project site would have no increase in daily production and no change in the hours of operationis proposed The Project would not create any new energy demand In addition there are no

adopted energy conservation plans applicable to the proposed Project As such the proposed Projectwould not conflict with any proposed energy conservation plans and impacts would be less thansignificant on a direct and cumulative basis

52 Does the project have environmental effects that willcause substantial adverse effects on human beingseither directly or indirectly


Findings of Fact

SMP 143R2 Finding No Substantial Change from Previous Analysis As indicated throughoutthe preceding analysis the proposed Project would not result in environmental effects which wouldcause substantial adverse effects on human beings either directly or indirectly

FLOOD RI DEPARTMENT

10FLOOD RI 1 SMP FLOOD HAZARD REPORT RECOMMND

Surface Mining Permit 00143 Revised Permit No 2 is a

proposal for a revision and consolidation of 3 existingmining operations in the Glen Ivy area of Temescal Canyonwest of Interstate 15 between Indian Truck Trail and

Trilogy Parkway The proposal would consolidate SMP 143R1SMP 150R1 and SMP 182 into SMP 143R2 Once consolidated

into a single mining operation the site will be

approximately 440 acres in size with 233 acres used for themining operation A single reclamation plan is alsoproposed with the consolidation of the 3 mines The Inert

Debris Engineered Fill Operation IDEFO is incorporatedinto the reclamation plan The proposal would also extendthe life of the operation by 50 years

North and northwesterly of the site are several othermining operations Residential development is located





10FLOOD RI 1 SMP FLOOD HAZARD REPORT cont RECOMMND

easterly of the site The Cleveland National Forest withsteep hilly terrain is located south and southwest of thesite A major tributary from these hills is Mayhew Canyonwith a drainage area of approximately 2200acres Storm

runoff originating from this canyon impacts the site in thevicinity of the southwest corner of the mining operationFlows then proceed northerly in an earthen channel MayhewCanyon Creek along the edge of the mining operation forabout 3000 feet The earthen channel collects additionalrunoff from several other smaller watersheds as flows

proceed northerly Within this earthen channel a coupleof small debris basins have been constructed and culverts

have been placed in the earthen channel to providevehicular access At the northerly boundary of the siterunoff enters a large rectangular concrete downdrainchannel which discharges flows into the SMP 139R1 miningpit

This proposal includes eventually 10 20 years afterissuance of this permit relocating this downdrain channelor other conveyance facility southerly toward the mouthof Mayhew Canyon and discharging flows into SMP 143R2 The

mining operation would excavate material starting in theeasterly portion of the site and proceed westerly throughthe mining site When it is determined that the excavationin the vicinity of the earthen channel is imminent a new

downdrain channel would be constructed While a conceptuallocation of the new downdrain channel is shown on theexhibit due to geological factors bedrock slopestability etc the exact location of this new downdrainchannel cannot be known at this time

In order to capture the flows coming out of Mayhew Canyonthe District recommends that the inlet to the downdrain

channel be located as close as possible to the mouth of thecanyon The downdrain channel should be able to collect

and convey the Q100 flow rate plus 50 bulking for debrisBased on the document titled Hydrology Study and DrainageAnalysis Surface Mining Permit SMP00139R1 County ofRiverside CA by Joseph E Bonadiman and Associates dated

August 2011 a 1 hour 100 year peak flow rate of 3648 cfscan be expected near the point where flows from MayhewCanyon enter this property site Using a 50 debrisloading factor the District recommends the inlet structure

and downdrain channel be designed using a minimum flow rateof 5472 cfs Provisions to prevent headcutting and scour

10FLOOD RI 1 SMP FLOOD HAZARD REPORT cont cont RECOMMND

at the inlet may be needed High velocity flows can beexpected as runoff enters the mining pit The channel and

the outlet will need to be designed to withstand these highvelocity flows and to minimize scarifying the concretechannel surface and prevent undermining the downdrainchannel

Once the construction of the downdrain channel is completeand material is removed from the earthen channeladditional drainage facilities may be needed to collect andconvey any tributary runoff Existing concrete Vditchesalong the southerly easterly and northerly edges of themining operation will remain to collect nuisance offsiterunoff and prevent these flows from entering the pit

The District does not object to this proposal

Response to Riverside County Planning Department Review ofSlope Stability Evaluation Report SMP00143R2 South ofTemescal Canyon Road and East of Maitri Road Glen Ivy Areaof Riverside County California dated September 8 2014

These documents are herein incorporated as a part ofGEO02280

GEO02280 concluded

1The active North Glen Ivy fault crosses to the northwestof the subject quarry in a northwesterly direction

2The South Glen Ivy fault also trends toward the

northwest and may also be active is located immediatelysouthwest of the south edge of the Werner Corporation pitsouth of the subject site3An unnamed fault crosses the west edge of the WernerCorporation property trending toward the northwest This

fault lies within the upper portion of the proposed westernpit slope This fault is likely to be potentially active

4Earth materials encountered on the subject site duringthe field exploration were identified a near surfacemanmade fills Af middle alluvial fan deposits QofCretaceous heterogeneous granitic rocks Khg and Bedford

Canyon formation Mzbc

5Groundwater is estimated to have the potential to rise toan elevation of 970 Mean Sea Level MSL




10PLANNING 29 SMP GEO02280 cont cont RECOMMND

6Gross slope stability analysis resulted in adequatefactors of safety for both static and pseudostaticconditions to the ultimate proposed depth of elevation 800MSL and with a groundwater elevation of 970 MSL

7Analyses for deep seated wedge failures indicated suchfailures are highly unlikely on the proposed slopes

8Exposed cuts in the Bedford Canyon formation are likelyto exhibit localized shallow wedge failures resulting inrelatively small amounts of rock sliding down the face ofthe cut slope

9It is the professional opinion of Hilltop GeotechnicalInc that the use of a 015g seismic coefficient wasappropriate and reasonable for use in the pseudo staticslope stability analysis for this site and is inconformance with current standards of practice for seismicdesign and appropriate for use in their calculations

10Surficial slope stability analyses indicated Factors ofSafety of 38and 33 respectively for the lower and

upper slopes in the alluvial materials

GEO02280 recommended

1Surface water should not be allowed to flow over the

existing andor proposed mining slopes other thanincidental rainfall

2Alterations of manufactured or natural slopes terracestop of slope berms etc should not be allowed that will

prevent runoff from being expediently directed to approveddisposal areas and away from the tops of slopes

3Surface drainage should be positively maintained in anon erosive manner

4Top of slope berms should be constructed and compacted aspart of any grading of the property and should bemaintained by the property owner

5The drainage patterns should be maintained throughout thelive of the proposed mine




10PLANNING 29 SMP GEO02280 cont cont cont RECOMMND

6Concentrated surface waters entering the property fromoff site sources should be collected and directed to apermanent drainage system and away from the top of miningslopes

7The property owner is responsible for the maintenance andcleaning of the interceptor ditches drainage terracesdowndrains and other drainage devices that have beeninstalled to promote slope stability

8The property owner should establish a program for theelimination of burrowing animals This should be an

on going program to protect slope stability

9The property owner should observe the drainage patternsduring heavy precipitation periods as this is often whentrouble occurs Problems such as gullying or pondingshould be corrected as soon as practicable

10High moisture content in slope earth materials is amajor factor in slope erosion and slope failuresTherefore precautions should be taken to minimize earthmaterial saturation

GEO02280 satisfies the requirement for a slope stabilityassessment for SMP00143R2 for planning purposes Final

approval of GEO02280 is hereby granted for SMP00143R2Further slope stability analysis will be required on anongoing basis as mining operations proceed Reporting ofslope stability analysis will be required annually as apart of the required annual mine inspection pursuant toSMARA regulations and as described elsewhere in thisconditions set

Dear Mr Straite

GLEN IVY MINEAMENDED RECLAMATION PLANCALIFORNIA ID 91 330001 0010 AND 0075SMP 143R2

The Department of ConservationsOffice of Mine Reclamation OMR has reviewed theamended reclamation plan for the Glen Ivy Mine The applicant Werner Corporation isproposing to consolidate three existing contiguous surface mining permits and continuemining aggregate on 233 acres of a 440 acre project site for a period of 50 years Therevision will bring all three mines under a single permit and reclamation plan reduce thetotal amount of disturbed acreage currently permitted and allow mining of reservesbetween the adjacent operations to continue The applicant estimates that a maximumof2500000 tons of material will be removed annually The project site is located in theTemescal Canyon area near Corona

The Surface Mining and Reclamation Act of 1975 SMARA Public Resources CodeSection 2710 et seq and the State Mining and Geology Board Regulations CaliforniaCode of Regulations CCR Title 14 Division 2 Chapter 8 Subchapter 1 require thatspecific items be addressed or included in reclamation plans The following commentsprepared by a restoration ecologist and an engineering geologist are offered to assist inyour review of this project The reclamation plan should be revised andorsupplemented to fully address these items Additionally the County will need to workwith OMRsReporting and Records Unit to close out mine numbers 91 330010 and 91330075 to finalize the consolidation of the three mines under the single mine number of91 330001

The Department of Conservationsmission is to balance todaysneeds with tomorrowschallenges and foster intelligent sustainableand efficient use of Californias energy land and mineral resources

Mining Operation and Closure

Refer to SMARA Sections 2770 2772 2773 CCR Sections 3502 3709 3713

SMARA Section 2773astates that the reclamation plan shall establish sitespecificcriteria for evaluating compliance with regard to topography and sediment and erosioncontrol The engineered drawings prepared by Bondiman and Associates Bondimanneed to be supplemented to include detailed topography and cross sections thataccurately depict how Mayhew Creek will be conveyed into the proposed concretedowndrain structure which will be a permanent diversion structure

End Land Use

Refer to SMARA Section 2772 CCR Sections 3707 3708

SMARA Section 2772c7requires that the reclamation plan include a description ofthe proposed use or potential uses of the mined lands after reclamation There is adiscussion on page 25 of possible end uses titled Post Reclamation OMR

recommends inserting a sentence to clarify this such as The end use for the propertyafter the completion of mining will be open space readily adaptable to other uses to bedetermined in the future

Hydrology and Water Quality

Refer to SMARA Sections 2772 2773 CCR Sections 3502 3503 3706 3710 3712

CCR Section 3706drequires berms and other erosion control methods to protectagainst gullying The reclamation plan maps prepared by Bondiman show a typicalsection for a VDitch but it is unclear on the map exactly where these VDitches bothexisting and proposed are or will be situated at the mine The reclamation plan shouldbe revised to include a discussion regarding the location of the VDitches and alsodescribe how they will be constructed and maintained The reclamation plan mapsshould be revised to clearly show where all VDitches are or will be constructed at themine

CCR Section 3706dalso requires berms and other water conveyance structures likeculverts and the concrete downdrain to be designed to handle runoff from not less thanthe 20year1 hour intensity storm event These calculations for the proposed reclaimedconditions were not included in the electronic version of the Preliminary HydrologyStudy and Drainage Analysis submitted to OMR Attachment 8 which is supposed toinclude proposed conditions and calculations on an attached compact disk CD wasnot included in the submittal to OMR The final version of the Hydrology Study andDrainage Analysis including all attachments must be submitted to OMR for review

CCR Section 3706e states that where natural drainages are rerouted by surfacemining activities mitigating alternatives shall be proposed and specifically approved in

the reclamation plan to assure that runoff shall not cause increased erosion orsedimentation The proposed reclamation plan includes the relocation of anapproximately 30footwide by 900foot long concrete downdrain structure that willconvey flow from Mayhew Creek down into the approximately 500 footdeep mining pitThe Bondiman maps currently show the downdrain structure in an area where MayhewCreek will have to make a 90degree turn and flow uphill in order to enter thedowndrain The reclamation plan must be revised to include design specificationsincluding detailed topography and cross sections that accurately depict how MayhewCreek will be conveyed into the proposed concrete downdrain structure

CCR Section 3706fstates that when stream diversions are required they shall beconstructed in accordance with the Stream and Lake Alteration Agreement between theoperator and the California Department of Fish and Wildlife DFW and therequirements of the Federal Clean Water Act The reclamation plan indicates that theserequirements have been met and it includes the specific agreement numbers OMRrecommends including these documents as an appendix to the reclamation plan toensure reclamation activities are carried out in accordance with these additionalregulatory requirements

Environmental Setting andProtection of Fish and Wildlife Habitat

Refer to CCR Sections 3502 3503 3703 3704 3705 3710 3713

Potential adverse effects from the mining operation will be identified and mitigation willbe proposed during the environmental review process Due to the fact that the projectis in the early stage of environmental review under CEQA it is recommended that theamended reclamation plan not be finalized or approved until mitigation is determinedsince mitigation measures recommended under CEQA may substantially change themanner in which mining and reclamation are accomplished

Planting 110 5gallon coast live oak trees as mitigation for impacts to oak trees isproposed in the General Biological Resources Assessment for the Glen Ivy MineProject by Alden Environmental Adjusting for some expected mortality will requireplanting additional trees Oak tree mitigation requirements with planting methods andperformance standards need to be added to the reclamation plan once mitigation isdetermined through the CEQA process Public Resources Code PRC 210834allowsreplanting to account for no more than half the mitigation requirements for the ProjectAdditional mitigation may be required such as purchasing an offsite conservationeasement

CCR Section 3705arequires that the density cover and speciesrichness of naturallyoccurring habitats shall be documented in baseline studies in order to establish a selfsustaining vegetative cover similar to the surrounding habitat Baseline studies of

reference areas must be collected and success criteria for revegetation must becalculated from this data prior to project approval The reclamation plan must berevised to include this data

Resoilinq and Revegetation

Refer to SMARA Section 2773 CCR Sections 3503 3704 3705 3707 3711

CCR Section 3711 establishes mandatory standards for topsoil salvage maintenanceand redistribution There is inadequate detail provided regarding topsoil managementto satisfy the minimum requirements of this section The reclamation plan must berevised to address subsections a through e of Section 3711

On page 22 it states that there is no topsoil on the project site and on page 29 it statesthat the expansion will result in very little additional salvage of topsoil However it alsostates that topsoil will be spread to a thickness of 6 inches which seems infeasibleconsidering the lack of available topsoil It will be extremely important to salvage asmuch topsoil as possible during the expansion of the mining footprint It will also beimportant to experiment in the test plots with different blends of topsoil and the silts andclays resulting from the washing process that are to be utilized as growth media as wellas with additional amendments and fertilizers It may be more appropriate to changethe terminology used in the reclamation plan to growth media if what is meant bytopsoil is actually a blend of soil and wash fines

CCR Section 3705mrequires that the reclamation plan include success criteria thatcan be quantified by cover density and species richness The success criteria givenunder Monitoring and Maintenance on page 29 state that The success criteria for therevegetation plan is 35 percent cover density and diversity of perennial species onsiteat the end of reclamation compared to the reference areas on adjacent landsWhereas 35 cover compared to baseline is a reasonable percentage for aridecosystems the target values for density and diversity should be higher than 35 ofbaseline Quantitative performance standards derived from baseline data must beprovided in the plan prior to approval An example of a table summarizing performancestandards is included below

Revegetation Performance Standards exampleCover 40 cover of native perennialsDensity XX native perennials per 50 meter by 1 meter transectSpecies richness X species of native erennials er 50meter b 1 meter transect

CCR Section 3705mrequires that the sampling methods should be set forth in theplan and the sample size should provide an 80 percent confidence level at a minimumMonitoring should be carried out annually until success criteria have been achieved Adescription of monitoring and sampling methods must be added to the plan and the plot


size such as 50meter by 1 meter transects should be incorporated into theperformance standards as shown in the table above

The reclamation plan includes a seed mix on page 28 to be applied by hydroseedingHowever there is ho description of planting the 110 5gallon coast live oak trees asspecified in the General Biological Resources Assessment for the Glen Ivy MineProject by Alden Environmental Adjusting for some expected mortality will requireplanting additionaltrees Oak tree planting methods and performance standards needto be addedlo the reclamation plan

CCR Section 3705krequires that noxious weeds be managed when they threaten thesuccess of the proposed revegetation spread to nearby areas or produce a fire hazardWeed control is discussed under Monitoring and Maintenance on page 29 but it isinadequate An effective weed control program must include a monitoring program withspecific threshold values weed cover or density per unit area that trigger control andabatement procedures In order to be effective weed control should be conducted bothduring operations and final reclamation The plan should be revised to include theseadditional details OMR noted abundant presence of the following noxious weedsduring the site visit castor bean Ricinus communis tamarisk Tamarix spp and treetobacco Nicotiana glauca Weed control measures should be implemented as soon aspossible to minimize the presence of these plants and to prevent their further invasion ofthe site

ExampleA weed management program shall be implemented including monthly monitoringNoxious weeds will be eradicated by mechanical or chemical methods when coverreaches 10 of any 100 squarefoot area

GLEN IVY MINE

RESPONSE TO COMMENTSCALIFORNIA MINE ID 91 330001 SMP 143R2

The Department of ConservationsOffice of Mine Reclamation OMR has reviewed theapplicantsresponses to comments for the Glen Ivy Mine dated January 13 2015 Theletter responds to comments provided in OMRsletter dated December 24 2014regarding the proposed amendment to the mining and reclamation plan Exhibits A Band C have been revised to incorporate the responses

The applicant Werner Corporation is proposing to consolidate three existingcontiguous surface mining permits and continue mining aggregate on 233 acres of a440 acre project site for a period of 50 years The revision will bring all three minesunder a single permit and reclamation plan reduce the total amount of disturbedacreage currently permitted and allow mining of reserves between the adjacentoperations to continue The applicant estimates that a maximum of2500000 tons ofmaterial will be removed annually The project site is located in the Temescal Canyonarea near Corona OMR staff conducted a site visit on December 8 2014 to view siteconditions and discuss reclamation issues

The Surface Mining and Reclamation Act of 1975 SMARA Public Resources CodeSection 2710 et seq and the State Mining and Geology Board Regulations CaliforniaCode of Regulations CCR Title 14 Division 2 Chapter 8 Subchapter 1 require thatspecific items be addressed or included in reclamation plans While most of OMRscomments have been adequately addressed the following remain outstanding

Mr Matt Straite

March 3 2015Page 2

Comment 4 CCR Section 3706dalso requires berms and other water conveyancestructures like culverts and the concrete downdrain to be designed to handle runoff fromnot less than the 20year1 hour intensity storm event These calculations for theproposed reclaimed conditions were not included in the electronic version of thePreliminary Hydrology Study and Drainage Analysis submitted to OMR Attachment 8which is supposed to include proposed conditions and calculations on an attachedcompact disk CD was not included in the submittal to OMR The final version of theHydrology Study and Drainage Analysis including all attachments must be submitted toOMR for review

Response 4 No culverts are proposed The concrete downdrain will be designed forthe Q100 bulked flow per the hydrology report Final design of the inlet structure anddown drain will be submitted to Riverside County prior to construction Additionally thefinal version of the Hydrology Study and Drainage Analysis including all attachmentswill be submitted to OMR as requested

The concrete downdrain structure design and supporting hydrologic calculations mustbe included in the reclamation plan Pursuant to SMARA final designs for waterconveyance structures must be included in the submittal to OMR prior to approval of asurface mining operationsreclamation plan Therefore the proposed responseindicating that the final design of the inlet or downdrain structure will be submitted to theCounty before it is constructed is inconsistent with the requirements of SMARAAdditionally OMR has not yet received the requested Attachment 8 of the HydrologyStudy and Drainage Analysis Please ensure that the requested design documents aresubmitted to OMR and that the design for the downdrain structure accounts for flowfrom not less than a 20year1 hour intensity storm event

Comment 12 CCR Section 3705m requires that the reclamation plan includesuccess criteria that can be quantified by cover density and species richness Thesuccess criteria given under Monitoring and Maintenance on page 29 state that Thesuccess criteria for the revegetation plan is 35 percent cover density and diversity ofperennial species on site at the end of reclamation compared to the reference areas onadjacent lands Whereas 35 cover compared to baseline is a reasonable percentagefor arid ecosystems the target values for density and diversity should be higher than35 of baseline Quantitative performance standards derived from baseline data mustbe provided in the plan prior to approval

Response 12 Biological resources have been studied and identified during bothEIR00359 and the Biological Resource Assessment conducted by Alden EnvironmentalThe seed mix density cover and species richness requirements for this project wereprovided by OMR staff during the 2013 permitting of neighboring SMP139R1 Anadditional baseline study will be conducted prior to final reclamation to ensureadequacy

Mr Matt StraiteMarch 3 2015Page 3

OMR reiterates that baseline studies and performance standards must be included inthe reclamation plan prior to project approval While OMR staff did assist theneighboring mine in revising their seed mix we did not provide suggested values fordensity cover and species richness In fact OMRscomment letter for that reclamationplan also noted the need for baseline studies on which to base their revegetationperformance standards Without baseline data the term 35 of baseline ismeaningless

Comment 14 The reclamation plan includes a seed mix on page 28 to be applied byhydroseeding However there is no description of planting the 110 5gallon coast liveoak trees as specified in the General Biological Resources Assessment for the Glen IvyMine Project by Alden Environmental Adjusting for some expected mortality willrequire planting additional trees Oak tree planting methods and performancestandards need to be added to the reclamation plan

Response 14 Oak tree planting will be in conformance with County of Riverside OakTree Management Guidelines The County of Riverside will approve all planting locationand methods prior to actual planting utilizing the countyscurrent standards andmethods

OMR reiterates that the number of oak trees planting methods and performancestandards need to be added to the revegetation portion of the amended reclamationplan They are a required component of site reclamation and therefore must beincluded in the reclamation plan Otherwise there is no way to include them in theFinancial Assurance Cost Estimate or the revegetation monitoring program

Notice of Preparation of a CEQA Document for theSurface Mining Permit No 143 Revised No 2 Project

The South Coast Air Quality Management District SCAQMD staffappreciates the opportunity to comment on theabove mentioned document The SCAQMD staffs comments are recommendations regarding the analysis of potential airquality impacts from the proposed project that should be included in the draft CEQA document Please send theSCAQMD a copy of the CEQA Document upon its completion Note that copies of the CEQA Document that aresubmitted to the State Clearinghouse are not forwarded to the SCAQMD Please forward a copy of the CEQA Documentdirectly to SCAQMD at the address in our letterhead In addition please send with the CEQA Document allappendices or technical documents related to the air quality and greenhouse gas analyses and electronic versions ofall air quality modeling and health risk assessment files These include original emission calculation spreadsheetsand modeling files not Adobe PDF files Without all files and supporting air quality documentation theSCAQMD will be unable to complete its review of the air quality analysis in a timely manner Any delays inproviding all supporting air quality documentation will require additional time for review beyond the end of thecomment period

Air Quality AnalysisThe SCAQMD adopted its California Environmental Quality Act CEQA Air Quality Handbook in 1993 to assist otherpublic agencies with the preparation of air quality analyses The SCAQMD recommends that the Lead Agency use thisHandbook as guidance when preparing its air quality analysis Copies of the Handbook are available from theSCAQMDsSubscription Services Department by calling 909 3963720 More recent guidance developed since thisHandbook was published is also available on SCAQMDswebsite here http wwwagmdgovhomeregulationscegaairquality analysishandbookcegaair qualityhandbook 1993 SCAQMD staff also recommends that the lead agency usethe CaIEEMod land use emissions software This software has recently been updated to incorporate uptodate state andlocally approved emission factors and methodologies for estimating pollutant emissions from typical land usedevelopment CaIEEMod is the only software model maintained by the California Air Pollution Control OfficersAssociation CAPCOA and replaces the now outdated URBEM1S This model is available free of charge atwwwcaleemodcom

The Lead Agency should identify any potential adverse air quality impacts that could occur from all phases of the projectand all air pollutant sources related to the project Air quality impacts from both construction including demolition ifany and operations should be calculated Constructionrelated air quality impacts typically include but are not limited toemissions from the use of heavyduty equipment from grading earth loadingunloading paving architectural coatingsoffroad mobile sources egheavyduty construction equipment and onroad mobile sources egconstruction workervehicle trips material transport trips Operation related air quality impacts may include but are not limited to emissionsfrom stationary sources egboilers area sources egsolvents and coatings and vehicular trips egon and offroadtailpipe emissions and entrained dust Air quality impacts from indirect sources that is sources that generate or attractvehicular trips should be included in the analysis

The SCAQMD has also developed both regional and localized significance thresholds The SCAQMD staff requests thatthe lead agency quantify criteria pollutant emissions and compare the results to the recommended regional significancethresholds found herehttpwwwagmdgovdocsdefaultsourcecegahandbookscagmdair qualitysignificancethresholdspdfsfvrsn2In addition to analyzing regional air quality impacts the SCAQMD staff recommendscalculating localized air quality impacts and comparing the results to localized significance thresholds LSTs LSTscanbe used in addition to the recommended regional significance thresholds as a second indication ofair quality impacts

Matt Straite 2 August 21 2014

when preparing a CEQA document Therefore when preparing the air quality analysis for the proposed project it isrecommended that the lead agency perform a localized analysis by either using the LSTs developed by the SCAQMD orperforming dispersion modeling as necessary Guidance for performing a localized air quality analysis can be found athttpwwwagmdgovhomeregulationscegaquality analysis handbooklocalizedsignificance thresholds

In the event that the proposed project generates or attracts vehicular trips especially heavyduty diesel fueled vehicles itis recommended that the lead agency perform a mobile source health risk assessment Guidance for performing a mobilesource health risk assessment Health Risk Assessment Guidancefor Analyzing Cancer Risk from Mobile Source DieselIdling Emissionsfor CEQA Air Quality Analysis can be found at http wwwagmdgovhomeregulationscegaairqualityanalysishandbookmobile sourcetoxicsanalysis An analysis of all toxic air contaminant impacts due to the useof equipment potentially generating such air pollutants should also be included

In addition guidance on siting incompatible land uses such as placing homes near freeways can be found in theCalifornia Air Resources BoardsAir Quality and Land Use Handbook A Community Perspective which can be found atthe following internet address http wwwarbcagovchhandbookpdfCARBsLand Use Handbook is a generalreference guide for evaluating and reducing air pollution impacts associated with new projects that go through the landuse decision making process

Mitigation Measures

In the event that the project generates significant adverse air quality impacts CEQA requires that all feasible mitigationmeasures that go beyond what is required by law be utilized during project construction and operation to minimize oreliminate these impacts Pursuant to state CEQA Guidelines 151264a1Dany impacts resulting from mitigationmeasures must also be discussed Several resources are available to assist the Lead Agency with identifying possiblemitigation measures for the project including

Chapter 11 of the SCAQMD CEQA Air Quality HandbookSCAQMDsCEQA web pages at http wwwagmdgovhomeregulationscegaairqualityanalysishandbookmitigation measures and control efficienciesCAPCOAsQuanting Greenhouse Gas Mitigation Measures available herehttpwwwcapcoaorgwpcontentuploads201011CAPCOAQuantificationReport914FinalpdfSCAQMDsRule 403 Fugitive Dust and the Implementation Handbook for controlling constructionrelatedemissions

Other measures to reduce air quality impacts from land use projects can be found in the SCAQMDsGuidanceDocument for Addressing Air Quality Issues in General Plans and Local Planning This document can be foundat the following internet address http wwwagmdgovdocsdefault sourceplanningairqualityguidancelcompleteuidancedocumentpdfsfrsn4
