("CEQA"), the State's CEQA Guidelines, California Code of Regulations, Title 14, Section 15000 et. seq., the City's Local CEQA Guidelines, and Government Code Section 65962.5(f)(Hazardous Waste and Substances Statement), the City of Rancho Palos Verdes prepared an Initial Study and determined that there is no substantial evidence that the approval for the Conditional Use Permit Revision and Grading Permit would result in a significant adverse effect on the environment, provided appropriate mitigation measures are imposed on the project. Thus, a Mitigated Negative Declaration was prepared and notice thereof was given in the manner required by law; and, WHEREAS, on December 12, 2017, the Planning Commission held a duly noticed public hearing, considered public testimony, and directed Staff to bring a resolution approving the project with revised conditions based on the Commission's input at the January 9, 2018 meeting. NOW, THEREFORE, THE PLANNING COMMISSION OF THE CITY OF RANCHO PALOS VERDES DOES HEREBY FIND, DETERMINE AND RESOLVE AS FOLLOWS: Section 1: The Planning Commission has independently reviewed and considered the proposed Mitigated Negative Declaration, the public comments upon it, and other evidence and finds that the Mitigated Negative Declaration was prepared in the manner required by law, and there is no substantial evidence, provided appropriate mitigation measures are imposed, that the approval of Case No. ZON2015-00230 would result in a significant adverse effect upon the environment. Section 2: There are no sensitive natural habitat areas on the subject site and, therefore, the proposed project will have no individual or cumulative adverse impacts upon resources, as P.C. Resolution No. 2018-01 Page 2 of 5 defined in Section 711 .2 of the State Fish and Game Code. Section 3: With the imposition of the following mitigation measures that address impacts upon aesthetics, air quality, geology and soils, hazards and hazardous materials, hydrology and water quality, land use and planning, and noise, and as set forth in the Mitigation Monitoring Program, Exhibit "B", which is attached hereto and incorporated herein by this reference, the proposed project's potential significant impacts will be reduced below a level of significance: AQ-1: Any maintenance areas at the site which are not located on existing paved areas shall be treated with an environmentally-friendly sealant or shall be watered down as often as needed in order to prevent the release of dust caused by the movement of heavy equipment such as skip loaders, dump trucks, etc. AQ-2: All trucks hauling soil, sand, and other loose materials shall be covered (e.g., with tarps or other enclosures that would reduce fugitive dust emissions), and shall have adequate freeboard to avoid spillage around the edges of the cover. AQ-3: All excavated materials (spoils) will be sufficiently watered and/or covered with properly secured tarps to prevent excessive dust. All fill materials shall be kept covered with properly secured tarps when not in use. Water sprays shall be used to minimize the release of fugitive dust when the spoils or fill material is delivered or removed. AQ-4: Prior to the final building inspection, the diesel fuel tank and associated equipment shall contain mechanisms to prevent the escape of vapors consistent with the City's adopted Uniform Building Code. AQ-5: Minimize idling time by requiring that equipment be shut down after 5 minutes when not in use (as required by the State airborne toxics control measure [Title 13, Section 2485 of the California Code of Regulations]). Provide clear signage that posts this requirement for workers at the entrances to the site and provide a plan for the enforcement of this requirement.

Land Use and Planning Biological Resources Aesthetics Population and Housing Energy/Mineral Resources Cultural Resources Geology and Soils Hazards and Hazardous Material Recreation Hydrology and Water Quality Noise Agricultural Resources Air Quality Public Services Mandatory Findings of Significance Transportation and Circulation Utilities and Service Systems Greenhouse Gas Emissions DETERMINATION: On the basis of this initial evaluation: I find that the project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. X I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project.A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a significant effect(s)on the environment,but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on earlier analysis as described on attached sheets, if the effect is a "potentially significant impact" or "potentially significant unless mitigated". An ENVIRONMENTAL IMPACT REPORT is required but must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effect (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR,including revisions or mitigation measures that are imposed on the proposed project Signature: ,4Date: t —1-12 Printed Name: Amy Seeraty, Senior Planner For: City of Rancho Palos Verdes Page 7 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 EVALUATION OF ENVIRONMENTAL IMPACTS: Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated 1.AESTHETICS.Would the proposal: a) Have a substantial effect on a scenic 1 vista? b) Substantially damage scenic resources, including, but not limited to,trees, rock outcroppings, and 1 1 historical buildings,within a state scenic highways? c) Substantially degrade the existing 1,12, 13, visual character or quality of the site 14 and its surroundings? d) Create a new source of substantial light or glare,which would adversely affect day or nighttime views in the area? _ Comments: a),b)The term"vista"is defined as a confined view in the City's General Plan,which is usually directed toward a terminal or dominant element or feature. Each vista has, in simplest terms, a viewing station, an object or objects to be seen, and an intermediate ground. Crest Road is identified as a vehicular corridor with views of the Pacific Ocean and Catalina Island in the opposite direction of the subject property oriented (to the south). The subject site is located on the north side of Crest Road and the proposed diesel fuel tank itself is only 5'- 3"tall, with the proposed vent piping reaching a maximum of 12' tall as measured from grade. Although the property slopes up approximately one foot from the existing 12' (at north side) office building, the majority of the proposed diesel fuel tank and vent piping will only impair the view of this existing building, thus the proposed project would not impact the defined scenic vista. Additionally, the existing as-built and proposed buildings and structures, as well as operations, on the site which are included in this analysis do not impair any scenic views or vistas, nor do they impair any views taken from adjacent residential properties. Furthermore,there are no known scenic resources on the subject lot that would be impacted by the proposed diesel fuel tank and the as-built structures. c)The site is developed with an as-built commercial/industrial (utility)use consisting of a water reservoir,and an administrative building and carport structure that was permitted in the early 1990s through Conditional Use Permit(CUP)No.172 and CUP No. 172,Revision"A".Although the site is surrounded by developed properties with single family residences, as the site is five acres in size and the proposed diesel fuel tank is clustered with other development located towards the center of the western portion of the lot the proposed project will not degrade the visual character of the site and its surroundings.Additionally,the tank will be mostly screened from view by existing foliage on the site,as well as existing buildings and fencing and existing site topography. Furthermore, a comprehensive landscaping and fencing plan is also proposed and will act to screen the facilities, operations and maintenance yard on the site which is also the subject of this Environmental Assessment. The incorporation of the following mitigation measures, the proposed project would cause less than significant impacts: AES-1: The proposed landscaping and fencing shall be installed per the Plan approved by the Director of Community Development within 60 days from the date of the Planning Commission's approval of Conditional Use Permit No. 172 Revision "C". Within 30 days from installation, the Director of Community Development shall determine whether additional screening is needed to adequately screen the existing and proposed uses and structures on the site from the neighboring residences. Page 8 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated AES-2:All existing and proposed foliage shall be trimmed on an annual basis as determined by the Director of Community Development in order to minimize any significant view impairment as seen from the adjacent residential properties. d) No lighting is proposed for the fuel tank installation or operation, and will therefore not create a new source of substantial light or glare which would adversely affect day or nighttime views in the area. The site is not proposed to be used during the evening hours for routine maintenance work, however, there may be emergency operations which will require the temporary use of lighting. The following mitigation measure will result in a less than significant impact with the use of temporary lighting for emergency operations: AES-3:Any temporary lighting used for emergencies shall be no taller than 10' in height and shall be pointed down to not cause excessive glare or light trespass onto any adjacent residential property or public street. 2.AGRICULTURE AND FORESTRY RESOURCES:Would the project: a) Convert Prime Farmland, Unique Farmland,or Farmland of Statewide Importance(Farmland),as shown on the maps prepared pursuant to the 2 Farmland Mapping and Monitoring Program of the California Resource Agency,to non-agricultural use? b) Conflict with existing zoning for agricultural use, or a Williamson Act 2 �1 contract? c)Conflict with existing zoning for, or cause rezoning of forest land (as defined in Public Resources Code section 12220(g)),timberland(as 2 defined by Public Resources Code section 4526), or timberland zoned Timberland Production(as defined by Gov't Code section 5104(g))? d) Result in the loss of forest land or conversion of forest land to non- 2 forest use? e) Involve other changes in the existing environment that,due to their location or nature, could result in 2 conversion of Farmland,to a non- agricultural use? Comments: The existing land use and zoning designations for the subject site are residential, and the existing utility use is permitted through Conditional Use Permit No. 172.Additionally,the subject site does not include any farmland, forest land, or timberland and is therefore not in conflict with the Williamson Act.Therefore,there would be no impact to agriculture caused by the proposed project. 3.AIR QUALITY:Would the proposal: a) Violate any air quality standard or contribute to an existing or projected 8 air quality violation? b) Expose sensitive receptors to substantial pollutant concentrations? Page 9 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non- attainment under an applicable federal or state ambient air quality standard(including releasing emissions that exceed quantitative thresholds for ozone precursors)? d) Create objectionable odors affecting a substantial number of people? e) Conflict with or obstruct the implementation of any applicable air quality plan? Comments: a), b)The operations of the site, including but not limited,to the installation of the diesel fuel tank,the temporary spoils and storage bin, and the use of heavy equipment has the potential to contribute to possible air quality violations by the release of fugitive dust from the site. However, with the incorporation of the following mitigation measures,the proposed project would cause less than significant impacts: AQ-1: Any maintenance areas at the site which are not located on existing paved areas shall be treated with an environmentally-friendly sealant or shall be watered down as often as needed in order to prevent the release of dust caused by the movement of heavy equipment such as skip loaders,dump trucks, etc. AQ-2:All trucks hauling soil,sand, and other loose materials shall be covered(e.g.,with tarps or other enclosures that would reduce fugitive dust emissions), and shall have adequate freeboard to avoid spillage around the edges of the cover. AQ-3:All excavated materials(spoils)will be sufficiently watered and/or covered with properly secured tarps to prevent excessive dust.All fill materials shall be kept covered with properly secured tarps when not in use.Water sprays shall be used to minimize the release of fugitive dust when the spoils or fill material is delivered or removed. c), e)The City of Rancho Palos Verdes is located within a five-county region in southern California that is designated as the South Coast Air Basin (SCAB). Air quality management for the SCAB is administered by the South Coast Air Quality Management Plan (AQMP) to address federal and state air quality standards. The adopted AQMP was prepared using planning projections based on locally adopted general plan and growth policies.The air quality of the subject site is expected to be substantially better than in most parts of SCAB region due to the more dominant influence of the ocean and its wind patterns. Additionally, the proposed diesel fuel tank is exempt from AQMP permit requirements, but will still have the proper equipment to prevent escape of any vapors,etc. d) The proposed diesel fuel storage tank has the possibility to create objectionable odors affecting a substantial number of people.The proposed maintenance operations have the potential to create objectionable odors from idling trucks and equipment. However, with the incorporation of the following mitigation measures, the proposed project would cause less than significant impacts: AQ-4: Prior to the final building inspection, the diesel fuel tank and associated equipment shall contain mechanisms to prevent the escape of vapors consistent with the City's adopted Uniform Building Code. AQ-5: Minimize idling time by requiring that equipment be shut down after 5 minutes when not in use(as required by the State airborne toxics control measure[Title 13, Section 2485 of the California Code of Regulations]). Provide clear signage that posts this requirement for workers at the entrances to the site and provide a plan for the enforcement of this requirement. Page 10 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated AQ-6: Maintain all construction equipment in proper working condition and perform all preventative maintenance. Required maintenance includes compliance with all manufacturer's recommendations, proper upkeep and replacement of filters and mufflers, and maintenance of all engine and emissions systems in proper operating condition. 4. BIOLOGICAL RESOURCES:Would the proposal: a) Have a substantial adverse effect, either directly or through habitat modifications,on any species identified as a candidate,sensitive, or special status species in local or 4 regional plans, policies,or regulations,or by the California Department of fish and Game or US Fish and Wildlife Service? b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, 4 regulations or by the California Department of Fish and Game or US Fish and Wildlife Service? c) Have a substantial adverse effect on federally protected wetlands,as defined by Section 404 of the Clean Water Act(including, but not limited 4 to, marsh,vernal pool, coastal, etc...),through direct removal,filling, hydrological interruption,or other means? d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or 4 �l migratory wildlife corridors, or impede the use of native wildlife nursery sites? e) Conflict with any local polices or ordinances protecting biological 4 resources, such as tree preservation policy or ordinance? 0 Conflict with the provisions of an adopted Habitat Conservation Plan or Natural Community Conservation 4 Plan, or other approved local, regional,or state habitat conservation plan? Comments: The City of Rancho Palos Verdes participates in the Natural Community Conservation Planning Act (NCCP)which is a state program adopted by the California Department of Fish and Game and the U.S. of Fish and Wildlife Service that helps identify and provide for the area-wide protection of natural wildlife while allowing for compatible and appropriate local uses. There are three types of vegetation communities identified in the Natural Page 11 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated Communities Conservation Plan (NCCP) and the General Plan. The subject site is a developed utility site and the portion where the diesel fuel tank is proposed to be located is paved and thus has no vegetation which would be removed as part of this project. Additionally, the other portions of the site where the existing maintenance and operational uses are proposed have lawn area, non-native trees, non-native plants, or bare soil. Furthermore,several of the bare areas are proposed to be landscaped with a variety of plants,including some native vegetation.Therefore, there would be no impacts to habitat,sensitive natural community,wetlands, protected or protected species,as none exist on the subject property. 5.CULTURAL RESOURCES:Would the proposal: a) Cause a substantial adverse change in the significance of a historical 1,7 resource as defined in§15064.5 of the State CEQA Guidelines? b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to 1,7 §15064.5 of the State CEQA Guidelines? c) Directly or indirectly destroy a unique paleontological resource or site or 1, 7 unique geological feature? d) Disturbed any human remains, including those interred outside of 1, 7 formal cemeteries? Comments:The project site is not located in the proximity of a known pre-historic or historic archaeological site, and no historical,archaeological,or paleontological resources are known to be on the project site.Additionally,the subject site is not located in areas the General Plan identifies as a historical resource or an archaeological site. Therefore, there will be no impacts to cultural resources a result of the proposed project. 6.GEOLOGY AND SOILS:Would the proposal: a) Expose people or structure to potential substantial adverse effects, deathincludininvolving:9 the k of loss, injury, or i) Rupture of a known earthquake fault,as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the 6 State Geologist for the area or based on other substantial evidence of a known fault? ii)Strong seismic ground shaking? 6 iii)Seismic-related ground failure, 6 including liquefaction? iv) Landslides? 6 b) Result in substantial soil erosion or the loss of topsoil? c) Be located on a geological unit or soil that is unstable,or that would become unstable as a result of the project, and potentially result in on or off site landslide, lateral spreading, Page 12 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated subsidence, liquefaction or collapse? d) Be located on expansive soil,as defined in the Uniform Building Code, thus creating substantial risks to life or property? e) Have soils incapable or adequately supporting the use of septic tanks or alternative wastewater disposal systems,where sewers are not available for the disposal of wastewater? Comments: a), b), c) The Alquist-Priolo Earthquake Fault Zoning Act's main purpose is to prevent the construction of buildings used for human occupancy on the surface trace of active faults. The Act only addresses the hazard of surface fault rupture and is not directed toward other earthquake hazards. According to the State of California Department of Conservation website,the City of Rancho Palos Verdes is not one of the cities identified as being affected by Alquist- Priolo Earthquake Fault Zones as of May 1, 1999. Additionally, the Seismic Zone Map released in March 25, 1999 (Redondo Beach Quadrangle) does not identify the subject site within any earthquake induced landslide and/or liquefaction zones. Furthermore, the proposed diesel fuel tank will require building permits and thus will meet safety standards for earthquake, landslide and liquefaction. As such, there would be no impact caused by the proposed diesel fuel tank. Additionally, the water system maintenance and operational activities involve temporary storage container structures,which do not require building permits. d)The proposed diesel fuel tank will be located on an existing paved area and will be improved with a concrete slab with curb that will be reviewed and permitted by the Building&Safety Division,as well as the Los Angeles County Fire Department.As such,there would be no impact caused by the proposed diesel fuel tank.The water system facilities, maintenance and operational uses and ancillary structures shall comply with all Building Codes, and so there would be no substantial risk to life or property. GEO-1: Building permits shall be obtained for all water system facilities, maintenance and operational uses, including any ancillary structures, if required. e) The proposed project will not contribute any additional wastewater to the existing sewer system, as the existing office buildings were originally permitted under CUP No. 172 and CUP No. 172 Revision "A", and no additional bathroom facilities are proposed,thus there would be no impact caused by the proposed project. 7.GREENHOUSE GAS EMISSIONS:Would the project: a) Generate greenhouse gas emissions, either directly or indirectly,that may have a significant impact on the environment? b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? Comments: a), b)The approval of the proposed Conditional Use Permit Revision"C"would allow for a 1,000 gallon above-ground diesel fuel tank and allow the water system maintenance operations onsite.Currently,there are no generally-accepted significance thresholds for assessing greenhouse gas (GHG) emissions. However, California's major initiatives for reducing climate change or greenhouse gas (GHG) emissions are outlined in Assembly Bill 32 (signed into law in 2006), a 2005 Executive Order and a 2004 Air Resources Board (ARB) regulation to reduce passenger-car GHG Page 13 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated emissions.These efforts aim at reducing GHG emissions to 1990 levels by 2020 (a reduction of approximately 30 percent) and then an 80-percent reduction below 1990 levels by 2050. Related to this requirement, the proposed project (diesel fuel tank and allowing existing maintenance activities to remain) should result in a reduction of emissions, as the diesel-powered vehicles and equipment already in service would no longer need to travel off the Peninsula to refuel at another Cal Water facility or gas station,thus reducing travel time and consequently emissions. In addition,the deliveries of the diesel fuel are proposed to occur approximately every 2-3 months,which would follow the same schedule as the delivery of gasoline for the existing 2,000 gallon above-ground gasoline tank.The property owner will also be using the same vendor for both gasoline and diesel. Because the delivery of the two fuels would follow existing schedule by the same vendor, there would be minimal need for additional delivery trips, and therefore result in a less than significant impact. Additionally, the use of the site as a maintenance facility will minimize the required distance traveled by Cal Water's vehicles, as these vehicles are only used for maintenance on the Peninsula. For these reasons, the GHG emissions associated with the proposed project would be less than significant and the proposed project would not conflict with an applicable plan, policy or regulation related to greenhouse gases. 8. HAZARDS AND HAZARDOUS MATERIALS:Would the project: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous material? b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? d) Be located on a site,which is included on a list of hazardous materials sites complied pursuant to Government Code Section 65962.5 1,2, 8 and, as a result,would create a significant hazard to the public or the environment? e) For a project located within an airport land use plan or,where such a plan has not been adopted,within two miles of a public airport or public use 1,2, 8 airport,would the project result in a safety hazard for people residing or working in the project area? f) For a project within the vicinity of a private airstrip,would the project result in a safety hazard for people 1,2, 8 residing or working in the project area? g) Impair implementation of, or 1, 2 Page 14 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated physically interfere with, an adopted emergency response plan or emergency evacuation plan? h) Expose people or structures to a significant risk of loss, injury, or death involving wildland fires, including where wildlands are 1,2,11 adjacent to urbanized areas or where residences are intermixed with wildlands? Comments: a), b), c)The proposed diesel fuel storage tank will store and dispense diesel fuel,which is considered a hazardous material to be used by the CWS's truck fleet and equipment. However, the proposed tank and dispensing equipment will incorporate features to contain the diesel fuel to the immediate site. In addition to being placed on a concrete pad with a curb, the proposed diesel fuel storage tank is manufactured to be a 1,000 gallon "Convault" aboveground storage tank.The tank will comply with Underwriters Laboratories (UL) Standard 142 for steel fuel storage tanks and UL Standard 2085 for aboveground storage tanks which are insulated and/or have secondary containment for flammable and combustible liquids to prevent spills which could create a significant hazard to the public or the environment. More specifically,the proposed tank will have four barriers to prevent fuel leakage:the first barrier is the steel tank itself,the second is a layer of thick Styrofoam (foam) insulation for fire protection and the third layer is an impervious barrier of 30 millimeter high-density polyethylene membrane (HDPE) which will contain any potential leakage from the steel tank itself.These first three layers are then,as a fourth barrier,encased in a six-inch thick layer of concrete which complies with the UL 2085 requirements for blast,fire,and ballistic impact protection.These barriers will prevent fuel leakage and consequently,prevent a hazard to the public and/or the environment.Also,the Petroleum Chemical Unit of the Health Hazardous Materials Division of the Los Angeles County Fire Department (Health Hazardous Materials Division) will review the plans for the proposed fuel storage tanks and will conduct field inspections of said tank prior to its use. There are no hazardous materials associated with the use of the facility for water system maintenance and operations other than the existing above-ground 2,000 gallon gasoline storage tank. However,as it may be possible that the spoils brought to the property may contain contaminants,to provide additional measures of certainty,the City will require periodic testing of the spoils soil for typical contaminants, including but not limited to heavy metals, etc. Thus, with the incorporation of the following mitigation measures, the proposed project would result in less than significant impacts: HAZ-1: Prior to issuance of any permits from the Building&Safety Division CWS shall satisfy the criteria from the following agencies by obtaining appropriate approvals: 1)Waste Management Division of the Los Angeles;2) County Department of Public Works for dispensing fuel and management of motor fuel waste products. 3)Approval from the Los Angeles County Fire Department for the installation of the new tank and pump. HAZ-2: Prior to issuance of any permits from the Building&Safety Division,CWS shall demonstrate that the proposed 1,000 gallon diesel fuel storage tank complies with Underwriters Laboratories (UL) Standard 142 for "Steel Aboveground Tanks for Flammable and Combustible Liquids" and UL Standard 2085 for "Protected Aboveground Tanks for Flammable and Combustible Liquids", by incorporating design features that create a barrier to prevent fuel leaks. HAZ-3: The spoils stored at the site shall be tested just prior to CWS's off-site disposal of the spoils and the results obtained before the material in the spoils bin is disposed of off-site. Testing shall include typical contaminants. The resulting report for these tests shall be forwarded to the City within one week of completion.Should any contaminants be found beyond the acceptable levels set by the United States Environmental Protection Agency, CWS shall be responsible for the appropriate disposal of the contaminated soil in a manner which complies with applicable state and federal law.This mitigation measure shall no longer be applicable after CWS relocates the spoils bin to a new site. Page 15 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated HAZ-4: Diesel fuel and oil will be used, stored and disposed in accordance with standard protocols for handling of hazardous materials.All personnel involved in use of hazardous materials will be trained in emergency response and spill control.Written evidence of this training shall be provided to City Staff within 15 days from the date the diesel fuel tank is put into service on the site. d)The site is not on a list of hazardous materials sites complied pursuant to Government Code Section 65962.5.Thus, there would be no impacts caused by the proposed project. e), f) There are no airports located within the City of Rancho Palos Verdes or in close proximity of the subject site. Therefore,there would be no impacts caused by the proposed project. g) The proposed fuel tank, including the facilities and operations, is located on a developed commercially-used site and will not block any evacuation routes.Therefore,there would be no impacts caused by the proposed project to any adopted emergency response plan or emergency evacuation plan. h) The proposed project is bounded by a public street to the north, developed commercial sites to the south, and developed residential properties to the southeast, east and west.Although the project site is located with a region of Very High Fire Hazard per CAL Fire, the proposed fuel tank and pump will be reviewed and permitted by the Los Angeles County Fire Department and there are also no wildlands in close proximity to the subject site.Thus, per the aforementioned reasons,there would be a less than significant impact caused by the proposed project. 9. HYDROLOGY AND WATER QUALITY:Would the proposal: a) Violate any water quality standard or 8 wastewater discharge requirements? b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that 8 there would be a net deficit in aquifer volume or a lowering of the local groundwater? c) Substantially alter the existing drainage pattern of the site or areas, including through the alteration of the course of a stream or river, in a manner,which would result in substantial erosion or siltation on or off site? d) Substantially alter the existing drainage pattern of the site or areas including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner that would result in flooding on or off site? e) Create or contribute runoff water which would exceed the capacity of existing or planned storm water drainage systems or provide substantial additional sources of polluted runoff? f) Otherwise substantially degrade Page 16 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated water quality? g) Place housing within a 100-year flood hazard area,as mapped on a Federal Flood Hazard Boundary or Flood Insurance Rate map or other flood hazard delineation map? h) Place within a 100-year flood hazard area, structures which would impede or redirect flood flows? i) Expose people or structures to a significant risk of loss, injury, or death involving flooding, including 10 flooding as a result of the failure of a levee or dam? j) Inundation by seiche,tsunami,or 10 mudflow? _ Comments: a,f)The proposed diesel fuel storage tank is manufactured to be a 1,000 gallon"Convault"aboveground storage tank. The tank will comply with Underwriters Laboratories(UL) Standard 142 for steel fuel storage tanks and UL Standard 2085 for aboveground storage tanks which are insulated and/or have secondary containment for flammable and combustible liquids to prevent spills that could adversely impact water quality. More specifically, the proposed tank will have four barriers to prevent fuel leakage: the first barrier is the steel tank itself, the second is a layer of thick Styrofoam(foam)insulation for fire protection and the third layer is an impervious barrier of 30 millimeter high-density polyethylene membrane (HDPE)which will contain any potential leakage from the steel tank itself. These first three layers are then, as a fourth barrier, encased in a six-inch thick layer of concrete which complies with the UL 2085 requirements for blast,fire,and ballistic impact protection.These barriers will prevent fuel leakage and consequently, contamination of any nearby water supply. The use of the facility for water system maintenance and operations will not substantially degrade water quality,as any temporary storage locations for spoils and/or fill materials shall comply with Best Management practices(BMPs) per the mitigation measures cited below. The proposed diesel fuel storage tank will also be located on a curbed concrete pad on which the tank will be bolted to comply with seismic safety requirements.The tank will also be surrounded by protective bollards that match those that secure the existing onsite generators. Prior to development, the City's Building & Safety Division will review drainage plans to ensure that the project complies with or obtains necessary National Pollutant Discharge Elimination System(NPDES)permits for stormwater discharges.The project will also be required to apply BMPs for run-off control during and after construction activities to prevent pollutants from entering the City's storm drains thus protecting the water quality. Based on the above, the following mitigation measures are intended to ensure the proposed diesel fuel tank and permanent and temporary operations of the site would cause less than significant impacts to hydrology and water quality: HWQ-1: Prior to any permit issuance by the City's Building and Safety Division, CWS shall submit for review and approval a drainage plan that complies with the National Pollutant Discharge Elimination System permits for stormwater discharges. HWQ-2: Prior to any permit issuance by the City's Building and Safety Division, CWS shall implement Best Management Practices (BMPs) for run-off control during and after construction activities to prevent pollutants from entering the City's storm drains. HWQ-3:Prior to issuance of any permits from the Building&Safety Division,CWS shall demonstrate that the proposed Page 17 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated 1,000 gallon diesel fuel storage tank complies with Underwriters Laboratories (UL) Standard 142 for "Steel Aboveground Tanks for Flammable and Combustible Liquids" and UL Standard 2085 for "Protected Aboveground Tanks for Flammable and Combustible Liquids", by incorporating design features that create a barrier to prevent fuel leaks. b)The water needs of the City of Rancho Palos Verdes are served by the CWS,which operates within the regulations and standards of the Public Utilities Commission. However, no additional water use is proposed as a part of the proposed diesel fuel tank, nor by the use the facility for water system maintenance, therefore, there would be no impacts caused by the proposed project. c, d, e) There are no streams or rivers on or in close proximity of the subject site. Currently, rainfall and runoff from existing commercially developed property flows into the existing drainage system. Additionally, the proposed diesel fuel tank is proposed to be located over an existing paved area,thus the proposed project would result in no additional run-off.Furthermore,no additional paved area is proposed as part of permitting the existing water system maintenance activities,beyond that which has existed since prior to City incorporation.Therefore,there would be no impacts caused by the proposed project. g,h) The properties within the City of Rancho Palos Verdes are exempted from Flood Hazard Maps due to their topographic nature. This action was initiated and accomplished by the County of Los Angeles prior to 1984 and this project will not affect the exemption.Therefore,the proposed project would have no impact. j) There are no dams and levees in the City of Rancho Palos Verdes. Given that there are no lakes, there is no potential exposure to seiche.Additionally,the subject site is not located within tsunami inundation areas,according to the State of California's tsunami inundation map (March 1, 2009). Furthermore, the subject site is flat and not in an area that would be subject to mudflow.Therefore,the proposed project would have no impact. 10. LAND USE AND PLANNING.Would the proposal: a) Physically divide an established community? b) Conflict with any applicable land use plan, policy, or regulation including, but not limited to the general plan, 1,2, 3, 8 specific plan, local coastal plan, or zoning ordinance? c) Conflict with any applicable habitat conservation plan or natural 1,4 �l community conservation plan? Comments: a)The 1,000 gallon diesel fuel tank is proposed to be located towards the center of an existing developed property, and thus will not physically divide an established community.Additionally,the water utility use has existing on the site since the early 1960s, prior to the construction of the surrounding residential neighborhood.Therefore, the proposed project would have no impact. b)The subject site is not located within the City's Coastal Zone or within special plan districts.The commercial office structure and the equipment storage shed structure were permitted through Conditional Use Permit No. 172 in 1992 and the CUP was amended in 1993 and 1997.The proposed project is to allow for the use of the site as a maintenance, and equipment and material storage yard for Cal Water,as well as for a diesel fuel tank, both of which are located on a commercially developed property in a residential zoning district.The Conditions of Approval set forth in Conditional Use Permit No. 172 and Revisions"A"and"B"will continue to be in effect,in addition to the new conditions of approval proposed for Revision "C". With the following mitigation measures in place, the proposed diesel fuel tank and operations would cause less than significant impacts: Page 18 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated LUP-1: Conditions of approval from Conditional Use Permit No. 172 and Revisions "A" and "B" shall remain in full force and effect as reflected in Condition No.22. In cases where contradictions exists between conditions,the stricter condition shall govern. c)There are no sensitive species identified in the Habitat Conservation Plan and/or Natural Community Conservation Plan that were found on the subject site.As such,the proposed project would cause no impact. 11. MINERAL RESOURCES.Would the proposal: a) Result in the loss of availability of a known mineral resource that would be of future value to the region and the residents of the State? b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local 8 General Plan, Specific Plan,or other land use plan? Comments: There are no known mineral resources found on the subject site, identified in the local General Plan, Specific Plan, or other land use plan. Additionally, the subject site is already developed with a commercial use and the areas where the proposed maintenance use or diesel fuel tank use will occur are either paved or have no below- ground grading (earth movement) proposed.Therefore,there is no impact caused by the proposed project. 12. NOISE.Would the project result in: a) Exposure of persons to or generation of noise levels in excess of standards established in the local General Plan 1 or noise ordinance, or applicable standards of other agencies? b) Exposure of persons to or generation of excessive groundbourne vibration 1,8 or groundbourne noise levels? c) A substantial permanent increase in ambient noise levels in the project 1,8 vicinity above levels existing without the project? d) A substantial temporary or periodic increase in ambient noise levels in 1,8 the project vicinity above levels existing without the project? e) For a project located within an airport land use plan or,where such a plan has not been adopted,within two miles of a public airport or a public 1,2 use airport,would the project expose people residing or working in the project area to excessive noise levels? f) For a project within the vicinity of a private airstrip,would the project expose people residing or working in 1,2 the project area to excessive noise levels? Page 19 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated Comments: a—d) The subject site currently serves as the maintenance yard for the California Water Services Company and is developed with several structures.As such, there is some degree of existing noise related to the operations. In order to minimize potential noise impacts caused by operations at the site, CWS will be relocating the materials bins to a temporary location, in the center of the maintenance yard,from their previous location at the north end of the property. This will be the location for the materials bins until July 9,2018, unless extended by the Planning Commission for one additional six-month period. CWS has also completed a noise study assessing the existing ambient noise levels, as measured at the north and east property lines(which abut residential properties), and to project the anticipated noise which was studied based on simulations of future spoils and materials operations within the temporary bin location in the maintenance yard.The spoils and materials simulation provided indicates that the noise produced by the loudest possible equipment(backhoe scraping&loading gravel&rock),will not exceed 65 dBA at any property line.To ensure that the noise levels during actual spoils pick and materials delivery events do not exceed 65dBA at all property lines, and align with the noise studies dated June 30,2017 and November 13, 2017, Staff will require a mitigation measure which requires that a follow-up noise study be conducted during an actual spoils pickup and during an actual materials drop-off.. Additionally, although OSHA (Occupational Safety and Health Administration) requires that construction vehicles use backup alarms,a mitigation measure has been added to minimize the potential noise impacts caused by these alarms. Regarding the proposed diesel fuel tank, it is proposed to be located over 100'from the nearest residential buildings (residences in the City of Rolling Hills Estates). The Municipal Code limits construction hours in the City from 7:00 a.m. to 6:00 p.m. Monday through Friday and between 9:00 a.m. and 5:00 p.m. on Saturdays. No construction shall be permitted on Sunday or legal holidays,as defined in the Municipal Code.Also,the noise specifications for the pump serving the diesel fuel tank have been obtained from the manufacturer and submitted by CWS indicating that the pump would not exceed 24 decibels at the unit,while the City's Municipal Code requires that noise levels from mechanical equipment do not exceed sixty-five dBA as measured from the closest property line.The hours of operation of the fuel tank and pump will be between 8:00 a.m.and 4:30 p.m. Monday through Friday.There will be some impacts from the delivery of the fuel, however,the deliveries are temporary in nature because they will only occur approximately every 2-3 months.Additionally,the temporary nature of construction noise,with the following mitigation measures,the short- term and long-term noise impacts would be less than significant for both the proposed diesel fuel tank and the maintenance operations onsite: N-1: Permitted hours and days for active construction activity are 7:00 a.m.to 6:00 p.m.,Monday through Friday,9:00 a.m.to 5:00 p.m.on Saturday,with no construction activity permitted on Sundays or on the legal holidays specified in Section 17.96.920 of the Municipal Code. During demolition, construction and/or grading operations, trucks shall not park, queue and/or idle at the project site or in the adjoining street rights-of-way before 7:00 a.m. Monday through Friday and before 9:00 a.m. on Saturday, in accordance with the permitted hours of construction stated in this condition.When feasible to do so,the construction contractor shall provide staging areas on-site to minimize off-site transportation of heavy construction equipment. These areas shall be located to maximize the distance between staging activities and neighboring properties,subject to approval by the building official. N-2: Noise generated by the daily operations, including the proposed fuel tank and pump and any other associated equipment, shall not exceed 65 dBA as measured from the closest property line. N-3: Not including spoils and materials pickup and delivery, deliveries involving commercial vehicles weighing in excess of 6,000 pounds shall be allowed only between the hours of 8:00 a.m.and 4:30 p.m., Monday through Friday, and between 9:00 a.m. and 4:30 p.m.on Saturday,with none occurring on Sunday and/or Federal Holidays. N-4:There shall be no use of the spoils or storage bins between the hours of 7:00 p.m.and 8:00 a.m.,Monday through Friday, nor before 9:00 a.m.or after 4:30 p.m.on Saturday,with none occurring on Sunday and/or Federal Holidays. Page 20 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated N-5: Unless safety provisions require otherwise,the construction contractor shall adjust all audible back-up alarms to the lowest volume appropriate for safety purposes (i.e. still maintaining adequate signal-to-noise ratio for alarm effectiveness). The contractor shall consider signal persons, strobe lights, or alternative safety equipment and/or processes as allowed for reducing reliance on high-amplitude sonic alarms. N-6: A noise study shall be completed within 30 days of the Planning Commission's approval of the CUP to assess the noise levels of a typical spoils pickup and a typical fill materials delivery at the closest property line. If it determined that the noise levels exceed 65dBA at any property line, CWS shall be required to install noise attenuation features, such as, but not limited to, portable noise barriers to reduce these decibel levels to less than 65dBA at the adjacent property lines. e, f)The City of Rancho Palos Verdes does not contain, border or is in close proximity of any airports to cause any impacts to cause exposure to noise levels resulting from an airport or a private air strip.Therefore,there would be no impact caused by the proposed project. 13. POPULATION AND HOUSING.Would the project: a) Induce substantial growth in an area either directly or indirectly(e.g. through projects in an undeveloped area or major infrastructure)? b) Displace existing housing, especially affordable housing? c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? Comments: a)As the proposed diesel fuel tank is only proposed to be utilized by the California Water Services Company,and not by the general public,the proposed project would not induce substantial growth in an area either directly or indirectly. Also, the proposed maintenance activity will be conducted by existing on-site staff. Therefore, there would be no impact caused by the proposed project. b-c)The subject site is a developed commercially-used lot. Therefore, there is no displacement of people or housing as a result and thus there would be no impact caused by the proposed project. 14. PUBLIC SERVICES. a) Would the project result in substantial j adverse physical impacts associated with the provisions of new or physically altered governmental facilities,the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response objectives tfore any of the followings or other nce public services: i) Fire protection? ii) Police protection? iii) Schools? iv) Parks? Page 21 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated v) Other public facilities? Comments: The subject site is a developed commercially-used lot and already has one above-ground fuel tank, a 2,000-gallon tank for gasoline to fuel the California Water Service Company vehicles.The proposed diesel fuel tank would not require an expansion of existing services or facilities.Additionally,the use of the site for water system maintenance and repair will not affect response times for any public services, and will help to maintain adequate water access for fire protection. Furthermore,the proposed tank and pump will be reviewed by the Los Angeles County Fire Department to ensure it can be utilized safely. For these reasons there would be no impact caused by the proposed project. 15. RECREATION. a) Would the project increase the use of neighborhood and regional parks or other recreational facilities, such that substantial physical deterioration of the facility would occur or be accelerated? b) Does the project include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment? Comments:The proposed diesel fuel tank and continuation of the maintenance yard use would not increase the use of neighborhood and regional parks or other recreational facilities,or include or require the expansion of recreational facilities. For these reasons there would be no impact caused by the proposed project. 16.TRANSPORTATION/TRAFFIC.Would the project: a) Conflict with an applicable plan, ordinance, or policy establishing measures of effectiveness for the performance of the circulation system,taking into account all modes of transportation including mass transit and non-motorized travel and relevant components of the circulation system, including but not limited to intersections, streets, highways and freeways, pedestrian and bicycle paths, and mass transit? b) Conflict with an applicable congestion management program, including, but not limited to level of service standards and travel demand measures,or other standards established by the county congestion management agency for designated roads or highways? c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that result in substantial safety risks? Page 22 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated d) Substantially increase hazards due to a design feature(e.g. sharp curves or dangerous intersections)or incompatible uses(e.g.farm equipment? e) Result in inadequate emergency access? f) Conflicts with adopted policies, plans, or programs supporting alternative transportation (e.g. bus turnouts, bicycle racks)? Comments: a, f) The property has been used by a water utility for over 50 years, prior to City incorporation, and therefore any traffic produced by the existing facility was included in the traffic analysis for the City's General Plan (page 119). Furthermore, according to CWS, the number of employees at the site has actually been reduced since the use was initiated in the early 1960s, as several administrative functions have been moved off site including customer service and meter reading. Furthermore,the original Conditional Use Permit No. 172 stated"...additional parking spaces for the company's approximately twenty(20)trucks and other assorted vehicles exist north of the office structure..", and that the proposed 4,000ft2 storage shed was required to comply with more stringent storage laws. The original CUP also stated that the new storage shed would serve to park several pieces of valuable mechanical equipment(backhoe, forklift,etc.)in an enclosed area for both for safety and preservation reasons. Because the majority of the 13 vehicles currently based on the subject property were captured in the original CUP,and because this existing fleet of vehicles already has access via Crest Road and Scotwood Drive,there should negligible changes to the ingress and egress trips,save for the spoils pickup and material delivery once a month.Thus,there would be no impacts to the circulation systems in relation to mass transit to conflict with any adopted policies, plans, or programs supporting alternative transportation.Therefore,there would be no impact caused by the proposed project. b) Deliveries of the fuel for the proposed diesel fuel tank will result in some additional trips, however, the impact of these will be negligible,as the delivery of the diesel fuel will only occur about once every 2-3 months,or approximately on a quarterly basis.In addition,the proposed fuel tank should reduce the number of trips required as the diesel-fueled vehicles and equipment currently utilized by California Water Service Company will not need to leave the site in order to refuel. c)The City of Rancho Palos Verdes does not border or is in immediate close proximity of any airports to cause any impacts to the air traffic due to the proposed project. Therefore, there would be no impact caused by the proposed project. d, e) No new design features, e.g, new driveway curb cuts are proposed as part of the project. Also, the proposed diesel fuel tank will not result in any impacts to existing emergency access as it is located towards the center of a developed commercial site,is clustered with other existing development and is not located in a roadway.Additionally, the proposed continued use of the site as a maintenance yard for the water system will not increase hazards as any as-built structures will be properly located on the site, i.e.outside of the existing driveways, so as to reduce the risk of collisions with any onsite vehicles and/or equipment. For these reasons there would be no impact caused by the proposed project. 17.UTILITIES AND SERVICE SYSTEMS.Would the project: a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? b) Require or result in the construction of new water or wastewater Page 23 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation Incorporated treatment facilities or expansion of existing facilities,the construction of which could cause significant environmental effects? c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities,the construction of which could cause significant environmental effects? d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? e) Result in a determination by the wastewater treatment provider,which serves or may serve the project,that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? g) Comply with federal, state, and local statures and regulations related to solid waste? Comments: The proposed diesel fuel tank and the use of the site as a water system maintenance and repair yard would not contribute any wastewater to the existing wastewater treatment facilities. However, the spoils which are proposed to temporarily continue at the site, will be taken on a monthly basis to a local landfill, which has the appropriate capacity.Thus,there would be no impact caused by the proposed project. 18. MANDATORY FINDINGS OF SIGNIFICANCE. a) Does the project have the potential to degrade the quality of the environment,substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? b) Does the project have impacts that are individually limited, but cumulatively considerable? Page 24 of 26 Environmental Checklist Case No.ZON2015-00230 January 9, 2018 Issues and Supporting Information Sources Potentially Less Than Less Than No Sources Significant Significant Significant Impact Impact with Impact Mitigation ' Incorporated ("Cumulatively considerable"means that the incremental effects of a project are considerable when viewed in connection with the effects of the past projects,the effects of other current projects, and the effects of probable future projects)? c) Does the project have environmental effects, which will cause substantial adverse effects on human beings, either directly or indirectly? Comments: a)The subject site does not contain and is not located within close proximity to areas with protected habitat or species. Therefore,there would be no impact caused by the proposed project. b)The proposed project has the potential to contribute to air quality, greenhouse gas emissions,water quality, noise hazards and hazardous material and land use and planning. However, none of these are significant with the mitigation measures which are proposed.Therefore,the proposed project would not result in a mandatory finding of significance due to cumulative impact considerations. c) There would be no substantial adverse direct or indirect effects on human beings with the mitigation measures described herein.That is,the impacts will be reduced to a less than significant level. 19. EARLIER ANALYSES. Earlier analysis may be used where,pursuant to the tiering,program EIR,or other CEQA process,one or more effects have been adequately analyzed in an earlier EIR or Negative Declaration. Section 15063 (c) (3) (D). In this case a discussion should identify the following items: a) Earlier analysis used. Identify earlier analyses and state where they are available for review. Comments: None b) Impacts adequately addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards,and state whether such effects were addressed by mitigation measures based on the earlier analysis. Comments: None c) Mitigation measures. For effects that are "Less than Significant with Mitigation Incorporated," describe the mitigation measures, which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions of the project. Comments: None 20.SOURCE REFERENCES 1 City of Rancho Palos Verdes, Rancho Palos Verdes General Plan,and associated Environmental Impact Report.

INTRODUCTION PURPOSE This Mitigation Monitoring Program (MMP) is to allow the following project at 5837 Crest Road, located north of Crest Road, in the City of Rancho Palos Verdes: The installation of a 1,000 gallon above-ground diesel fuel tank to fuel California Water Service trucks and equipment and to memorialize the existing facilities and operations. The MMP responds to Section 21081.6 of the Public Resources Code, which requires a lead or responsible agency that approves or carries out a project where a Mitigated Negative Declaration has identified significant environmental effects, to adopt a "reporting or monitoring program for adopted or required changes to mitigate or avoid significant environmental effects." The City of Rancho Palos Verdes is acting as lead agency for the project. An Initial Study/Mitigated Negative Declaration was prepared to address the potential environmental impacts of the project. Where appropriate, this environmental document recommended mitigation measures to mitigate to a less than significant level or avoid impacts identified. Consistent with Section 21080 (2)(c) of the Public Resources Code, a mitigation reporting or monitoring program is required to ensure that the adopted mitigation measures under the jurisdiction of the City are implemented. The City will adopt this MMP when adopting the Mitigated Negative Declaration. ENVIRONMENTAL PROCEDURES This MMP has been prepared in accordance with the California Environmental Quality Act of 1970 (CEQA), as amended (Public Resources Code Section 21000 et seq.) and the State Guidelines for Implementation of CEQA (CEQA Guidelines), as amended (California Administrative Code Section 15000 et seq.). This MMP complies with the rules, regulations, and procedures adopted by the City of Rancho Palos Verdes for implementation of CEQA. MITIGATION MONITORING PROGRAM REQUIREMENTS Section 21081.6 of the Public Resources Code states: "When making the findings required by subdivision (a) of Section 21081 or when adopting a negative declaration pursuant to paragraph (2) of subdivision (c) of Section 21081, the public agency shall adopt a reporting or monitoring program for the changes to the project which it has adopted or made a condition of project approval in order to mitigate or avoid significant effects on the environment. The reporting or monitoring program shall be designed to ensure compliance during project implementation. For those changes which have been required or incorporated into the project at the request of an agency having jurisdiction by law over natural resources affected by the project, that agency shall, if so requested by the lead or responsible agency, prepare and submit a proposed reporting or monitoring program." Mitigation Monitoring Program Exhibit B - Page 1 Resolution No. 2018-01 II. MANAGEMENT OF THE MITIGATION MONITORING PROGRAM ROLES AND RESPONSIBILITIES The MMP for the project will be in place through all phases of the project including final design, pre-grading, construction, and operation. The City will have the primary enforcement role for the mitigation measures. MITIGATION MONITORING PROGRAM PROCEDURES The mitigation monitoring procedures for this MMP consists of, filing requirements, and compliance verification. The Mitigation Monitoring Checklist and procedures for its use are outlined below. Mitigation Monitoring Program Checklist The MMP Checklist provides a comprehensive list of the required mitigation measures.
