Zoning Designation(s): Mixed Industrial(MI) 8. Description of Project: Introduction Blue Line Transfer, Inc. (Blue Line)is proposing to develop an Anaerobic Digestion(AD) Facility ("the project")that Nvould be capable of processing 10,000 tons per Near(tp)r) of food Nvaste and green Nvaste into biogas (gaseous product generated by the degradation of organic matter under anaerobic conditions)that Nvould be cleaned and converted into biogenic compressed natural gas (CNG). The project is expected to produce 56,000 diesel equivalent gallons (dge) per Near of CNG, enough fuel for four to five CNG-fueled collection vehicles. The project Nvould be located at the Blue Line Materials Recovery Facility (MRF) in the City of South San Francisco (see Figure I and Figure 2). The South San Francisco Scavenger Company, Inc. CNG collection vehicle fleet is also located at the Blue Line MRF and Nvould be fueled by the CNG produced by the project.

The anaerobic digestion process occurs naturally in marshes and Nvetlands. There are a variety of controlled systems where AD technology is currentIv utilized in the United States including wastewater treatment facilities and dairy manure digesters and co-digesters. In other countries (primarily in Europe), AD technology is utilized to process and treat municipal solid Nvaste (MSW)to recover energy and to reduce the volume of solid Nvaste that must be landfilled. AD facilities that process solid Nvaste produce biogas and digestate(liquids and solids).Within the digester,decomposition occurs in a four phases: hydroloysis,acidogenesis,acetogenesis, and methanogenesis resulting in methane, carbon dioxide, Nvater and digestate/residuals. Digestate is the remaining solid and/or liquid residuals from the AD process. Project System Components The AD system proposed for this project Nvould be a dry fermentation process,using a Zero Waste Energy(ZWE) Smartferm design,Nvhere received feedstock is subject to an inoculated percolate to promote anaerobic digestion. The generated biogas is purified to pipeline quality CNG using a BioCNG system,provided by Cornerstone Engineering, and the compression and fueling system (also provided by Cornerstone)is designed to match directly up Nvith the BioCNG system.Thermal and electrical energy Nvould be provided by a Capstone microturbine, Nvhich is considered Best Available Control Technology (BACT)for air emissions. Electrical poNver Nvould be supplied by a combination of the microturbine and grid-supplied poNver. Process Description The project operational process is summarized in the folloNving steps, depicted in Figure 3, and described in greater detail below: 1. Source-separated organic Nvaste from South San Francisco Scavenger Company CNG collection vehicles Nvould be delivered to the project and placed in the 48-foot by 20-foot aeration bav; 2. The food Nvaste and green Nvaste Nvould be blended together(approximately 50:50 ratio) in the aeration bav and loaded into the AD system for a 21-dav dry fermentation process for the generation of biogas; 3. Biogas Nvould be recovered and collected; 4. Biogas Nvould be upgraded to fuel quality(SAE J1616 Standards); 5. The upgraded biogas Nvould be compressed and stored as CNG fuel on site; 6. The CNG fuel Nvould be used in the South San Francisco Scavenger Company CNG collection vehicles,Nvhich are fueled on site; 7. Digestate Nvould be removed from the anaerobic digesters and placed in an in-vessel compost system(for four to five days)for ammonia removal and odor control; 8. The digestate Nvould then be transported to the Z-Best Composting Facility in Gilroy.

The organics Nvould then be loaded into the AD system for the recovery*of biogas.Biogas Nvould be recovered and sent to a BioCNG system that Nvould upgrade the biogas to fuel quality*(about 99%methane) and produce a Nvaste gas of 40%methane. The Nvaste gas Nvould be used to operate a microturbine. The heat from the microturbine Nvould be used to heat the percolate and maintain the organics at thermophilic (>122°F)temperatures. The fuel quality*biogas Nvould be compressed and stored and Nvould be used to fuel Nvaste collection vehicles. After a retention time of about 21 days, biogas generation Nvould be exhausted and the digestate Nvould be removed from the AD system and placed in an in-vessel composting chamber for 4 to 5 days. Air Nvould be drav'n through the material to strip ammonia, Nvhich could be an odor issue at the facility*or at the composting facility*receiving the digestate.This off-gas Nvould be passed through an acid scrubber to remove ammonia, and then passed through a biofdter to oxidize emissions and minimize odors,trace ammonia, and volatile organic compounds(VOCs).Exhaust air streams that Nvould be treated in the biofllter include aeration bay*exhaust air,digester start-up and termination air,and acid scrubber exhaust air. Notably*,there Nvould also be an enclosed lean gas flare(LGF),v hich Nvould destroy lov, quality lean biogas(methane content below 20%and higher than I%)generated toNvards the termination of the AD process cycle,when the majority*of the biogas generation has been exhausted. The LGF Nvould be intermittently*operated 3 to 4 hours per digester termination,which Nvould occur even*2.5 to 3 days. Biogas Cleanup System The biogas from this AD system Nvould have a methane content of about 60%and Nvould be generated at a rate of 3,000 cubic feet per ton of Nvaste. The biogas cleanup system Nvould use an Air Liquide MEDAL membrane system to produce a fuel flow that is approximately*99% methane.The published Low Carbon Fuel Standard(LCFS)pathways for biogas to CNG assume that a two-stage membrane system is used,Nvhich recovers 90%of the methane in the biogas. HoNvever,for small scale systems,the cost of a two-stage membrane is prohibitively*expensive. Therefore, a one-stage membrane Nvould be used for this system,Nvhich results in a carbon dioxide-rich Nvaste gas that Nvould be about 40%methane and used as fuel for a microturbine to provide energy*to operate the facility*. Power Supply The total electrical load of the project Nvould be 132.7 kW,including the AD system,in-vessel composting system, biogas upgrading and fueling system, and the microturbine processor. There Nvould also be a requirement for thermal energy*to heat the AD system. The waste gas from the biogas cleanup system Nvould be used in a microturbine to generate both electrical and thermal energy*. The microturbine is about 28%efficient, and the biogas flow to the Blue Line Biogenic CNG Facility 6 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration microturbine Nvould generate about 73.3 kW of electric poNver(553%of the total), as Nvell as more than sufficient thermal energy to satisA-the process requirements. This is based on a stainless steel heat transfer module,rather than copper, due to concerns about corrosion. The balance of electrical requirements(59.4 kW)Nvould be satisfied Nth grid supplied poNver.If the microturbine is doN-,n for repair or maintenance,grid-supplied poNver Nvould provide all of the electricity and thermal energy to the system until the microturbine is operational. Co-Product Generation Solid digestate Nvould be produced through the AD system,Nvhich Nvould be taken to the Z-Best Composting Facility in Gilroy and Nvould ultimately be used as a soil amendment. As stated above, the organic Nvaste feedstock for this AD system Nvould be a 50:50 blend of food and green waste,Nvith an average moisture content of 60%. The Nveight of digestate Nvould be about 10%less than the as-received feedstock. Fuel Production The annual CNG methane production is estimated at 8,585,676 cubic feet,which is expected to offset the use of approximately 56,000 gallons of diesel fuel. Project Component Perspectives Visual simulations of the front and back of the project components are depicted in Figure 4 and Figure 5,respectively. Project Construction Activities The components of the system Nvould be provided by three vendors,Zero Waste Energy for the anaerobic digestion component, Cornerstone Engineering for the biogas upgrading and fueling system and Capstone Turbine Corporation Nvould furnish the microturbine for the reneNvable energy generation.A goal of the project is to demonstrate the construction of an entirely modular, small-scale,biofuel production facility Nvith the system components designed to integrate and complement each other. Ease of construction Nvith complementary system components that can easily be scaled up to larger facilities is a key goal of this project. Construction activities associated Nvith the project Nvould be minimal based on the modular technologies incorporated into the design. Construction is anticipated to occur over a 2-to 3-month period,which would include disturbing an area of 0.44 acres and export of 2 230 cubic yards during preliminary earthNvork and grading. 9. Surrounding Land Uses and Setting: The project Nvould be located on the Blue Line MRF site,which is bordered on the east and south by San Francisco Bay, and business parks to the north and Nvest. The area surrounding the project continues to change (as envisioned in the East of 101 Area Plan) from prior heavy industrial and trucking uses toNvard a range of lighter industrial uses, as Nvell as office and research uses.

FreeNya-,T access is most convenient from the East Grand Avenue exit,or the South Airport Avenue exit from US 101, or from the North Access Road exit from the US 101/1-380 interchange. 10. Project Objectives: Project goals and objectives are to promote sustainability in the community,Nyhile addressing global environmental concerns,including: • Help Blue Line meet Target 2.1 and Target 4.2 of their 2011 First,'ustainability Report. Target 2.1 plans to convert 86%of the fleet to loNy/no emission technology by 2020, including seeking sources of biogenic CNG. Target 4.2 plans to increase the landfill diversion rate to 75%by 2020. • Assist the City of South San Francisco to reduce their carbon footprint by 15%from a 2005 baseline by 2020. • Assist in meeting CalRecycle Strategic Directive 6.1: Reduce the amount of organics in the Nyaste stream by 50 percent by 2020. • Support Assembly Bill '12 (AB 32),the California Global Warming Solutions Act of 2006, greenhouse gas (GHG)reduction measures related to the use of anaerobic digestion: • Measure E-3. Achieve a 33 percent renevyable energy mix by 2020. (AD facilities produce biogas Nyhich is a renevyable energy source.) • Measure RW-3. High Recycling/Zero Waste. (Anaerobic digestion is one of five subcategories listed under this measure.) • Meet the LoNy Carbon Fuel Standard(LCFS),Nyhich requires a 10%reduction in the carbon intensity of fuel by 2020. The use of CNG fuel produced from biogas reduces the carbon intensity by 62%from diesel. • Support mandated commercial recycling pursuant to AB 341 and local government plans. • Provide digestate to be composted and used as a soil amendment, contributing to the reduction of CO2 and agricultural Nyater runoff. • Commercialize a technology that can be replicated at a local level throughout the state. 11. Other Public Agencies whose Approval is Required (e.g.,permits,financing approval,or participation agreement. Indicate Nyhether another agency is a responsible or trustee agency): The Solid Waste Facility Permit(SWFP)Nyould need to be revised to accommodate the change in operations to add the AD Facility and CNG Production Facility at the Blue Line MRF. The Project proponent Nyill need to file the application Nyith the San Mateo County Environmental Health Services Division, acting as the Local Enforcement Agency(LEA),for the California Department of Resources Recycling and Recovery (Ca1Recycle). The LEA issues the SWFP Revision, and CalRecvcle needs to concur Nyith the SWFP Revision. Blue Line Biogenic CNG Facility 10 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration The CNG Production Facility Nvould convert the excess Nvaste gas from the biogas clean-up process in a microturbine to generate electricity to run the facility. The Bay Area Air Quality Management District(BAAQMD)Nvill need to issue an Authority to Construct and a Permit to Operate (ATC/PTO)the microturbine. The BAAQMD considers microturbines to be BACT. In addition to the microturbine,the BAAQMD Nvill need to issue ATC/PTO for the lean gas flare,the acid scrubber, and the biofilter.

Discussion The Blue Line MRF is on an 11. 7 acre Nvaterfront site located on the southeast corner of the Point San Bruno Peninsula in the city of South San Francisco's East of 101 Planning Sub-area. San Francisco Bav is on the east side and the mouth of San Bruno Canal is on the south side. To the north of the MRF site is a biotech research campus Nvith multiple three,four and five story office buildings and a parking structure(see Figure 6 for an Aerial Overview of the area). Further to the northNvest is Point San Bruno Hill,the highest point in the area. Access to the site, about 1.5 miles east of State Highvmy US 101, is via East Grand Avenue, through a light industrial and commercial Nvarehousing area that now is converting to research facilities and offices. The block-long side streets of Haskins Way and East Jamie Court dead-end at San Francisco Bav and the Blueline MRF,respectively,and link the MRF Nvith East Grand Avenue. Both streets are Nvide, offering truck access to the range of uses in the vicinity.Warehouses are on the north side of East Jamie Court (see Photo 1, Figure 7), and to the south are two new office buildings Nvith south facing Nvaterfront views. The MRF is an active facility Nvith multiple buildings. Trucks move about, entering and exiting, transferring loads,Nvith people and equipment engaged in truck maintenance, bin Nvashing and material sorting. The area is kept clean,landscaping and pedestrian Nvalks green the entry*area and the perimeter is landscaped.Most of the site is surrounded by an 8 foot Nvall,providing a buffer to the Bav Trail Nvhich circumnavigates three sides of the site. The Nvestern perimeter near the entrance has a wrought iron fence that allows views into the site and out to the Bay.

SOURCE:ESA,2012 Blue Line Biogenic CNG Facility. 120353 Figure 7 Photographs from East Jamie Court Initial Study/Mitigation Negative Declaration From the East Jamie Court entrance the most visible building is the Administration Building on the southNvest corner of the site(as seen in Photo 2, Figure 7). It is approximately 10,000 square feet and 40 feet tall. Adjacent to it is the Maintenance Building, a two story building also about 10,000 square feet in size. The truck Wash Building is also approximately 40 feet tall, cubicle in shape and about 3,000 square feet near the center of the northern perimeter of the site. The Wash Building is directly east of the proposed AD Facility and approximately the same height, so this existing building can be used to approximate the visual effects of the proposed facility. The largest of the buildings is the MRF,Nvhere trucks unload materials and green Nvaste for recovery, the building is approximately 100,000 square feet and is approximately 40 feet high. Trucks are routed in a one Nvav traffic circle around the perimeter of the site to transfer the Nvaste and exit back out onto East Jamie Court. The San Francisco Bay Trail South of the Facility The San Francisco Bav Trail follows the shoreline from Nvest of the MRF and continues around the outside of the southern and eastern shoreline edges of the facility Nvhere it crosses a Nvetland area to the north and continues northNvard past the neighboring biotech campus. Views across the Nvater are present along this entire length. To the south,across the inlet of the San Bruno Canal is the San Francisco Airport, about 1.5 miles away. Southeast are distant views across the Nvater to the San Mateo Bridge and to the east are open Nvater views Nvith the East Bay hills in the distance. The Nvater draws the attention of most Bav Trail viewers. At the main entrance to the MRF on East Jamie Court is a designated Bay Trail parking area,trailhead and linkage to the trail(see Photo 3,Figure 8). Looking north across East Jamie Court from the public parking area is the perimeter Nvall surrounding the MRF and above that is the parking structure that overlooks the MRF site. The proposed AD Facility Nvould be in front of the parking structure,nearIv as long and about two-thirds the height of the existing structure. The proposed site is approximately 200 feet away from the Bay Trail parking lot. Similar,though more distant views are available from the Bay Trail itself,v hich follov,s the shoreline some 450 to 500 feet to the south. Views of the site are northNvard across the currently unoccupied parking lot that is just Nvest of the MRF Administration Building (see Photo 4, Figure 8). The neighboring parking structure is plainly visible and vegetation filters views of the base of the structure. The wrought iron fence that allows views into the MRF site is also visible to the right. Views like this are available for approximately 300 feet along the Bay Trail,until the Administration Building and the opaque perimeter Nvall prevent any further vieNving into the MRF. The Bay Trail continues to the east around the MRF Nvhere it begins to head northNvard. From locations near the MRF immediate views are focused on perimeter landscaping and scenic open Nvater views, the San Mateo Bridge, and the distant East Bay hills.

The Trail briefly parallels the northern perimeter Nvall of the MRF and is directly aligned Nvith the narrow side of the proposed AD Facility which Nvould be 600 to 800 feet avmv from the trail. From this perspective the site is only partially visible because of intervening vegetation. The Bav Trail becomes slightly elevated as it crosses a bridge over a small Nvetland and offers more direct views in the direction of the proposed AD Facility(see Photo 6, Figure 9). The parking structure is in the center right of the photo and the Wash Building is in the center-left. The Wash Building is the approximate height of the proposed structure that would sit directly to the left of it (in Photo 6). Just above the bridge in the biotech campus are designated parking spaces for access to the Bav Trail. From the Bay Trail parking area the AD Facility Nvould be approximately 600 feet avmv and Nvould be nearly the same height(see Photo 7, Figure 10) as the Wash Building in teal and blue. Vegetation and foreground grades Nvould screen loNver portions of views from the Bay Trail parking area. The total distance of the Bay Trail east of the facility that Nvould be exposed to any partial views of the AD Facility Nvould be approximately 600 linear feet. The Biotech Research Campus Two buildings and the parking structure have views in the direction of the proposed AD Facility. While there are many more buildings in the campus,two of those buildings have facades facing the proposed AD Facility that are not blocked by other buildings. These two buildings are approximately 200 and 800 feet avmy from the proposed AD Facility. Currently these buildings have views of the existing 100,000 square foot MRF Building,the Wash Building,the Maintenance Building, and the more distant Administrative Building. The Parking Structure and Vegetative Band The parking structure is four stories tall Nvith rooftop parking on the fifth level.The exterior elevation alternates between solid Nvalls that enclose the cars up to Nvaist height and openings that open to the Nveather. BeN,-een the parking structure and the proposed AD Facility is a vegetative band Nvith large Nvoody shrubs and trees that is approximately 50 feet Nvide Nvhich acts as a visual buffer between the adjacent campus facilities and the Blue Line MRF. Views out of the structure towards the MRF vary*depending upon the level,though consistently one must be near the southern edge of the structure to see anything other than the concrete structure and cars. From the ground level views southNvard out of the parking structure are nearly*completely*filled Nvith green vegetation. From the second level, approximately*half of the views are still filtered by the taller vegetation. From the third level views become open Nvith the shoreline and Bay in the distance and the MRF in the middleground. Looking doom,vegetation is in the foreground.

Upper portions of the Aeration Chamber Nyould likely be vieNvable over the concrete Nyall,Nyith vieNys filtered by intervening tree landscaping. The AD Facility Nyould be located in the northNyestern corner of the existing MRF,just south of the neighboring parking structure (see Figure 6 above for location). The maximum height of the proposed AD Facility is 31 feet,Nyhile nearly half the length of the structure is only 20 feet high. The parking structure to the north is approximately 40 feet high and provides a visual backdrop to vievys of the AD Facility from the south and southNyest(see Figure 11, Elevations). The Wash Building is of similar height just east of the proposed AD Facilitv and both the Maintenance Building and the Administration Building are of similar height though considerably larger. The proposed AD Facility Nyould be set back from the terminus of East Jamie Court by approximately 150 feet so that distant vieNys from the Nyest Nyould be screened by the Nyarehouse structure and landscaped parking lot also to the Nyest. The approximately 50 foot Nyide vegetative buffer along the northern border of the property and along the south side of the parking structure Nyould also filter vieNys for those looking out of the ground floor of the parking structure. The environmental checklist issues are discussed beloNy. a) No Impact.VieNys to San Francisco Bay Nyaters from the Bay Trail Nyould remain unaffected since the AD Facility Nyould be on the land side of anv Bav Trail vievys. When vievyed from the Nyater,the AD Facility Nyould bareh-be visible,and onh-from narrovy vievy corridors direeth-south and direct Iv east of the AD Facility.When visible N-, thin these narrovy corridors, the AD Facility Nyould be loNver than existing buildings around it,including the parking structure,the MRF,the Administration Building and various surrounding buildings. There are no designated scenic vistas in the area, and therefore there is no impact. b) No Impact. There are no state, county or local scenic highvmys in the vicinity. Since the site is currently a paved parking area,no damage Nyould occur to any trees,rock outcroppings or historic buildings. There is no impact associated Nyith resources surrounding scenic highv ay s. C) Less than Significant. The proposed AD Facility Nyould be located in a paved corner of the existing MRF betvyeen a Nyarehouse, a larger parking structure and a utilitarian Wash Building,and as such the visual character of the immediate site is that of an active Nyorkplace, Nyith a moderate level of visual quality. The placement of the proposed AD Facility among existing buildings of similar scale and matching the MRF exterior paint palette limits its visibility from many public perspectives. It Nyould not be visible from the Nyestern half of East Jamie Court,from most of the Bav Trail,from most of the business park to the Nyest,and most of the biotech research facility.The places where it Nyould be visible from the Bay Trail include tNyo short Nyindovys; one to the south and one directly east. Much of the existing landscaping Nyould also serve to screen vieNys of the proposed AD Facility,including from Blue Line Biogenic CNG Facility 20 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 r T N d T5 LL a�i LL N LL N 0 N U � U O � � IIII o o b m M IN y o o� o � 0000� m O j Z b b o b B oW j 8 L o > _ = o j 0� Y000000= 0000000 W i 0 „ o ww o r r e ,,,'i 1 ,, ; o a w o / o w % i ' .�.. fijU O O Y C l9 m G) J l9 C O C G) r C N 4) O) l9 a s N H Initial Study/Mitigation Negative Declaration the Bay Trail parking area on East Jamie Court, which is the closest public view of the proposed project. Existing vegetation Nvould also serve to screen views from the lower levels of the neighboring parking structure. As seen in Figures 12 and 13, doN-,award views from the parking structure Nvould change some of the parking lot views into rooftop views. Construction of the proposed AD Facility Nvould convert some of the existing truck parking into a structural element within the site,and there Nvould be an associated minor visual change to the visual character of the area.This visual change Nvould not substantially diminish the visual quality of the site or the surroundings because the primary visual qualities of the site Nvould still remain; views to the Bav Nvould remain; the Bav Trail Nvould offer two glimpses of the new structure while still providing unencumbered views of the Bay. Sensitive receptors Nvould also have glimpses of the new structure from acute angles,though vegetation is largely already in place to continue screening and could be managed to further support that objective.As such,the Design Review Board has indicated that additional landscaping Neill be required in areas where screening is not adequate and to maintain and/or enhance the visual quality of the site.There Nvould be a perceptible change at the site Nvith the construction of a new structure, but it would be consistent Nvith the existing industrial visual character of the site and Nvould not be a substantial degradation of the visual quality of the site or its surroundings;therefore,the impact Nvould be less than significant. d) Less than Significant. The project includes lighting on the buildings and parking areas. All lighting Nvould be required to conform to the City standards on outdoor lighting. All lighting Nvould be fully cutoff and positioned to minimize off-site impacts by being directed inNvard towards the site and doN-,award Nvith appropriate shielding and awa-,T from the Bav and Bav Trail.Exterior building and parking lot lighting for the new AD Facility Nvould be similar to the lighting that already exists in the parking areas.In addition to lighting, the project Nvould include an enclosed flare to combust low quality biogas.The flare could potentially operate during daytime or nighttime hours;hov,ever,it Nvould be enclosed in order to prevent any visual light or glare impacts.The project would not significantly affect nighttime views in the area and therefore the impacts Nvould be minimal and less than significant.

AGRICULTURAL AND FOREST RESOURCES— In determining whether impacts to agricultural resources are significant environmental effects,lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model(1997)prepared by the California Dept.of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland,are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state's inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project;and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board. Would the project: a) Convert Prime Farmland,Unique Farmland,or Farmland of Statewide Importance(Farmland),as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency,to non-agricultural use? b) Conflict with existing zoning for agricultural use,or a Williamson Act contract? c) Conflict with existing zoning for,or cause rezoning of,forest land(as defined in Public Resources Code section 12220(g)),timberland(as defined by Public Resources Code section 4526),or timberland zoned Timberland Production(as defined by Government Code section 51104(g))? d) Result in the loss of forest land or conversion of forest land to non-forest use? e) Involve other changes in the existing environment which,due to their location or nature,could result in conversion of Farmland to non-agricultural use or conversion of forest land to non-forest use? Discussion a-b) No Impact. The project site is not designated by either the General Plan or the Zoning Ordinance as agricultural. There is no Williamson Act contract on the property. The proposed project Nvould not affect farmland or agricultural uses in any Nvay. The project Nvould,therefore,have no impact on farmland or agricultural activities of any kind. c-e) No Impact. The project site is not zoned or designated for forestry or timberland uses. Therefore,there Nvould be no impacts related to these resources.

AIR QUALITY— Where available,the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project: a) Conflict with or obstruct implementation of the ❑ ❑ ® ❑ applicable air quality plan? b) Violate any air quality standard or contribute ❑ ® ❑ ❑ substantially to an existing or projected air quality violation? 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 which exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial pollutant ❑ ❑ ® ❑ concentrations? e) Create objectionable odors affecting a substantial ❑ ® ❑ ❑ number of people? Discussion a) Less than Significant. The project site is Nvithin the San Francisco Bay Area Air Basin (Bay Area),Nvhich is currently designated as a nonattainment area for state and national ozone standards, state particulate matter(PM10 and PM2.5) standards, and federal PM2.5 (24-hour) standard. The BAAQMD's 2010 Clean Air Plan (BAAQMD, 2010)is the applicable Clean Air Plan that has been prepared to address ozone nonattainment issues. If a City s General Plan is consistent Nvith the most recently adopted Clean Air Plan,a project that is consistent Nvith the General Plan's land use designation is considered consistent Nvith applicable air quality plans and policies. As stated in Section 10, Land Use and Planning,the proposed project Nvould be consistent Nvith the General Plan land use designations and zoning for the project site. In addition, the City s General Plan is consistent Nvith the Clean Air Plan because data and projections from the General Plan are incorporated into the Clean Air Plan. Development of the project Nvould not interfere Nvith population and vehicle-miles-traveled(VMT)projections used to develop the 2010 Clean Air Plan planning projections as it Nvould not increase the population of the area and any change in VMT traveled Nvould be negligiblet. Furthermore, less ozone precursors and less particulates Nvould be emitted from the combustion of CNG than diesel(Edgar and Associates,2012a). Therefore,the proposed project Nvould result in t Some food and greenwastes are already being shipped to Z-Best in Gilroy. Blue Line Biogenic CNG Facility 27 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility a less-than-significant impact because it Nvould not substantially conflict Nvith the region's air quality management plan. b) Less than Significant with Mitigation. The BAAQMD adopted new thresholds of significance on June 2010 and new CEQA Air Quality Guidelines (BAAQMD 2011)for the analysis of criteria air pollutants and toxic air contaminants(TACs).Notably,the thresholds BAAQMD adopted Nvere called into question by a minute order issued January 9, 2012 in California Building Industry Association v. BAAQMD, Alameda Superior Court Case No. RGI0548693. The minute order states that"The Court finds [BAAQMD's adoption of thresholds] is a CEQA project, the court makes no further findings or rulings." Subsequently,on March 5,2012,the judge in the case issued a final decision and judgment Nvhich ruled that the BAAQMD CEQA Guidelines constitute a project under CEQA and that the District must"set aside all approvals in [the resolution approving the Guidelines] and ... not disseminate these or anv new approvals of officially sanctioned air quality thresholds of significance until the District fully complies Nvith CEQA."The claims made in the case concerned the CEQA impacts of adopting the thresholds,i.e.how the thresholds Nvould affect land use development patterns, and petitioners argued that the thresholds for Health Risk Assessments encompassed issues not addressed by CEQA. Those issues are not relevant to the scientific soundness of the BAAQMD's analysis of v hat levels of pollutants should be deemed significant. The thresholds Nvill not cause any impacts in terms of land use development patterns insofar as this project is concerned, because the project Nvould not change the land use at the site. Accordingly, ESA Nvill use the thresholds and methodologies(as deemed appropriate for this project)from the 2011 BAAQMD CEQA Air Quality Guidelines to determine the potential impacts of the project on the existing environment. Construction The Bav Area Air Basin experiences occasional violations of ozone and particulate matter (PM10 and PM2.5) standards. Thus, during the construction phase of any given project basin N ide violations can occur.The proposed demolition of the parking lot and the subsequent redevelopment into the AD Facility Nvould result in emissions primarily from construction related vehicles. Construction Nvould involve use of equipment and materials that Nvould emit ozone precursor emissions (i.e.,reactive organic gases or ROG, and nitrogen oxides, or NOx). Construction activities Nvould also result in the emission of other criteria pollutants from equipment exhaust, construction-related vehicular activity, and construction Nvorker automobile trips. Emission levels for these activities Nvould vary depending on the number and type of equipment,duration of use,operation schedules,and the number of construction workers. Criteria pollutant emissions of ROG and NOx from these emission sources Nvould incremental1v add to the regional atmospheric loading of ozone precursors during project development. Emissions Nvere estimated using the CalEEMod model and are depicted below in Table 1. Additional assumptions and information are included in Appendix B. Blue Line Biogenic CNG Facility 28 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration TABLE 1 PEAK DAY CONSTRUCTION-RELATED POLLUTANT EMISSIONS(Pounds/Day)a Exhaust Exhaust Year ROG NOx CO SOz PM10b PM2.5b 2013(Unmitigated Emissions) 3 18 15 <1 8 1 BAAQMD Construction Threshold 54 54 None None 82 54 Significant Impact? No No No No No No a. Emissions were modeled using CaIEEMod and assumes pavement removal and export of approximately 2,230 cubic yards of excavated soils,as well as the substantially modular development of the project.Construction activities were assumed to occur for a duration of three months.Additional information is included in Appendix B. b. BAAQMD's construction-related significance thresholds for PM10 and PM2.5 apply to exhaust emissions only and not to fugitive dust. Although the project Nvould not generate emissions during construction that Nvould exceed the BAAQMD thresholds, due to the non-attainment status of the air basin Nvith respect to ozone,PM10, and PM2.5,the BAAQMD recommends that projects implement a set of Basic Construction Mitigation Measures (BAAQMD,2011)as best management practices (BMPs) regardless of the significance determination. Implementation Mitigation Measure AIR-1 Nvould reduce impacts to a less-than-significant level. Mitigation Measure AIR-1: During active construction, the applicant shall require construction contractors to implement all the BAAQMD's Basic Construction Mitigation Measures,listed below: 1. All exposed surfaces (e.g.,parking areas, staging areas, soil piles,graded areas, and unpaved access roads) shall be Nvatered two times per day,or more often if needed to control fugitive dust. 2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered. 3. All visible mud or dirt track-out onto adjacent public roads shall be removed using Nvet poNver vacuum street sweepers at least once per day. The use of dry poNver sweeping is prohibited. 4. All vehicle speeds on unpaved roads shall be limited to 15 mph. 5. All roadvmvs, drivevmvs, and sideNvallcs to be paved shall be completed as soon as possible. Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. 6. Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations [CCR]). Clear signage shall be provided for construction workers at all access points. 7. All construction equipment shall be maintained and properly tuned in accordance Nvith manufacturer's specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation. Blue Line Biogenic CNG Facility 29 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility 8. Post a publicly visible sign Nvith the applicant's telephone number and person to contact regarding dust complaints. This person shall respond and take corrective action Nvithin 48 hours. The Air District's phone number shall also be visible to ensure compliance Nvith applicable regulations. Operations The proposed project Nvould generate pollutant emissions from operations through the folloN ing sources: on-road mobile,a front end loader,the microturbine energy generation, the lean gas flare, and composting. These sources are described in more detail below. For on-road mobile sources,the project Nvould result in changing yardwaste pickup to a Nveekly cycle(three daily trucks)rather than the existing biweekly cycle(t�vo daily trucks), With the additional truck traveling an average of 30 miles per day. For offroad equipment,the front end loader is assumed to be 125 horsepoNver and Nvould operate 3.5 hours per day, 5 days per Nveek. The microturbine Nvould generate electric and thermal poNver for the sNTstem,approximately 73.3 kW of the total 132.7 kW required for the system. The lean gas flare is only operated for 3 to 4 hours per digester termination Nvhich occur every 2.5 to 3 days. Emission factors for these sources Nvere incorporated from the updated information for the CEC grant(Edgar and Associates, 2012a) and stationary source emissions specifications (Edgar and Associates, 2012b). Volatile organic compounds (VOCs, also called reactive organic gases [ROG]) from composting of the digestate Nvere determined using the California Integrated Waste Management Board(CIWMB)factor for Nvindrows (CIWMB,2007),Nvith a 90%reduction applied due to pile enclosure and pumping the off- gas to the biofilter. Operational emissions Nvere estimated and are depicted below in Table 2. Additional assumptions and information are included in Appendix B. As shoN-,n in Table 2,long-term operational emissions of the project Nvould be less than significant.

No No No No No a Assumptions and specific emission factors are included in Appendix B. C) Less than Significant with Mitigation. According to the BAAQMD,no single project is sufficient in size to, by itself, result in nonattainment of ambient air quality standards. Instead, a project's individual emissions contribute to existing cumulatively significant Blue Line Biogenic CNG Facility 30 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration adverse air quality impacts.Notably,if a project exceeds the identified significance thresholds, its emissions Nvould be cumulatively considerable,resulting in significant adverse air quality impacts to the region's existing air quality conditions. Alternatively,if a project does not exceed the identified significance thresholds,then the project Nvould not be considered cumulatively considerable and Nvould result in less-than-significant air quality impacts. As discussed for criteria"b"above,the project Nvould result in less than significant construction emissions Nvith mitigation incorporation, and less than significant operational emissions. Mitigation Measure: Implement Mitigation Measure AIR-1. d) Less than Significant. The project Nvould be located at an existing parking area at the Blue Line MRF site, adjacent to existing industrial and office uses. In regards to short- term construction and long-term operations,the project is not expected to have any negative health impacts on the local population,given local meteorological conditions,the considerable distance to the nearest residents, and the transient nature of the employees of businesses in the surrounding area. In addition, as described in the CEC grant application(Edgar and Associates, 2012a), the microturbine specified for use in this project, a Capstone C65 microturbine designed to operate on digester gas, has been permitted for similar use at locations Nvithin both the BAAQMD and South Coast Air Quality Management District (SCAQMD), at both landfills and Nvastewater treatment facilities. This microturbine has been certified under the California Air Resources Board Distributed Generation Certification Program. Although this does not constitute an air pollution permit,both the BAAQMD and SCAQMD consider this type of microturbine Nvith a Distributed Generation Certification to constitute BACT.In previous permitting efforts—in both the BAAQMD and SCAQMD— assessments of the health impacts of TACs have revealed that the emissions from the Capstone C65 microturbine,Nvhen equipped Nvith the proper emissions control devices (such as those that Nvould be employed Nvith this project and required for a Permit to Operate by BAAQMD)do not create an unacceptable cancer risk or non-cancer chronic hazard to the public. e) Less than Significant With Mitigation. Odors are generally regarded as an annoyance rather than a health hazard. Manifestations of a person's reaction to odors can range from psychological (e.g.,irritation, anger, or anxiety) to physiological (e.g., circulatory and respiratory effects,nausea, vomiting, and headache). The ability to detect odors varies considerably among the population and overall is quite subjective.People may have different reactions to the same odor.An odor that is offensive to one person may be perfectly acceptable to another(e.g., coffee roaster). An unfamiliar odor is more easily detected and is more likely to cause complaints than a familiar one. KnoN-,n as odor fatigue, a person can become desensitized to almost any odor and recognition only occurs Nvith an alteration in the intensity. The occurrence and severity of odor impacts depend on the nature,frequency and intensity of the source,Nvind speed and direction, and the sensitivity of receptors. Odor impacts should be considered for any proposed new odor sources located near existing receptors, as Nvell as anv new sensitive receptors located near existing odor sources. The storage and transfer of greenNvaste and foodwaste materials during anaerobic digestion and composting Blue Line Biogenic CNG Facility 31 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility processes of the project Nvould be potential sources of odor at the adjacent land uses.Without adequate procedures and controls the odors from the feedstock materials could generate very* strong odors.Notably*, BAAQMD has several rules regarding odors (Regulation 1-301 (Public Nuisance) and Regulation 7(Odorous Substances))that the project must meet. In addition,composting facilities,Nvhich are regulated by CalRecyTcle,are required to have an Odor Impact Minimization Plan(OIMP)as required by laxv and codified in the California Code of Regulations, Title 14 (Natural Resources), Division 7 (CIWMB), Chapter 3.1 (Compostable Materials Handling Operations and Facilities Regulatory*Requirements), Article 3 (Report of Facility*Information), Section 17863.4 (Odor Impact Minimization Plan).Although the project is not considered a composting facility,the compostable materials handling operations of the project Nvould require an GIMP. The OIMP includes two major components, a Complaint Response Protocol and an Odor Complaint Reporting Format. The Odor Complaint Response Protocol describes the procedures to follow upon receiving a complaint. The protocol includes measures to identIA-the odor and requires appropriate adjustments to storage, process control, and facility*improvements to reduce odors. Implementation of Mitigation Measure AIR-2 Nvould apply*odor control measures to the project,Nvhich Nvould reduce impacts to a less-than-significant level. Mitigation Measure AIR-2: The applicant shall develop and comply*Nsith an Odor Impact Minimization Plan(OIMP)pursuant to the requirements of the California Code of Regulations, Title 14, Division 7, Chapter 3.1, Article 3, Section 17863.4. Once complete,the OIMP shall be submitted to the LEA for a 30-day*period for review and comment.

BIOLOGICAL RESOURCES—Would the project: 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 regional plans, policies,or regulations,or by the California Department of Fish and Game or U.S. 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,regulations or by the California Department of Fish and Game or U.S. 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 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 migratory wildlife corridors, or impede the use of native wildlife nursery sites? e) Conflict with any local policies or ordinances ❑ ❑ ❑ protecting biological resources,such as a tree preservation policy or ordinance? f) Conflict with the provisions of an adopted Habitat ❑ ❑ ❑ Conservation Plan, Natural Community Conservation Plan,or other approved local, regional,or state habitat conservation plan? Discussion a-c) No Impact. The project site is currently comprised of paved parking lot for the Blue Line MRF. As such,development of the project Nvould not have an--effect on candidate,sensitive, or special status species. In addition,there is no riparian habitat or other sensitive natural community onsite. Finally,the project site is largely impervious and contains no Nvetlands as defined by the Clean Water Act. Implementation of the project Nvould have no impact on these biological resources. d) Less than Significant with Mitigation. The area north of the project site (between the Blue Line MRF property boundary and the existing parking structure) could be suitable habitat for nesting birds due to the presence of trees. Breeding birds are protected under Section 3503 of the California Fish and Game Code(the Code),and raptors are protected under Section 3503.5.In addition,both Section 3513 of the Code and the Federal Migratory Bird Treaty Act(16 USC, Sec. 703 Supp.I, 1989)prohibit the killing,possession,or trading of migratory*birds. Finallv, Section'1800 of the Code prohibits the taking of non-game birds, Nvhich are defined as birds occurring naturally*in California that are neither game birds nor Blue Line Biogenic CNG Facility 33 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility fully protected species.Nesting birds near the project site could be negatively impacted by project construction and increased noise associated N ith project operations. These potential impacts Nyould be reduced to less-than-significant levels Nyith the implementation of Mitigation Measure BIO-1. Mitigation Measure BIO-1:Prior to construction during the months of March to August, a qualified biologist shall conduct pre-construction surveys to locate any active nests no more than 14 days prior to these construction activities. These nesting bird surveys shall be performed in the project area and surrounding 500 feet,in coordination Nyith the City. Construction activities performed beN,-een September and February Nyould avoid the general nesting period for birds and therefore Nyould not require pre- construction surveys. If active nests are observed on the project site or surrounding area,the project applicant shall establish buffer zones around the nests,N ith the size to be determined in consultation Nyith California Department of Fish and Game (usually 100 feet for perching birds and 300 feet for raptors).No ground-disturbance activities shall occur Nyithin this buffer zone until young have fledged or the nest is othenyise abandoned. If Nyork during the nesting season stops for 14 days or more and then resumes,then nesting bird surveys shall be repeated,to ensure that no neNy birds have begun nesting in the area. e) No Impact. The project site contains an existing parking lot that has little to no biological resource value.The project,therefore,Nyould not conflict N ith any local policies or ordinances protecting biological resources. Implementation of the project Nyould have no impact. f) No Impact. The project site is not covered by a Habitat Conservation Plan or Natural Community Conservation Plan. Therefore,the project Nyould not result in impacts related to this criterion.

CULTURAL RESOURCES—Would the project: a) Cause a substantial adverse change in the ❑ ❑ ❑ significance of a historical resource as defined in §15064.5? b) Cause a substantial adverse change in the ❑ ❑ ❑ significance of an archaeological resource pursuant to §15064.5? c) Directly or indirectly destroy a unique paleontological ❑ ❑ ❑ resource or site or unique geologic feature? d) Disturb any human remains, including those interred ❑ ❑ ❑ outside of formal cemeteries? Discussion a-d) No Impact. As determined in the,'outh,San Francisco Scavenger Company Materials Recovery Facility and Transfer Station EIR(City of South San Francisco, 1998), since the project site Nvas entirely under Nvater until about 1970, and since the project site is currently a parking lot that had previously been disturbed through filling,grading, and paving,there is little likelihood that the site contains any significant cultural resources. Therefore,the project Nvould result in no impact to these cultural resources.

GEOLOGY,SOILS,AND SEISMICITY— Would the project: a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury,or death involving: i) Rupture of a known earthquake fault,as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault?(Refer to Division of Mines and Geology Special Publication 42.) ii) Strong seismic ground shaking? iii) Seismic-related ground failure,including liquefaction? iv) Landslides? b) Result in substantial soil erosion or the loss of topsoil? c) Be located on a geologic 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,subsidence,liquefaction, or collapse? d) Be located on expansive soil,as defined in Table 18-1-B of the Uniform Building Code(1994), creating substantial risks to life or property? e) Have soils incapable of adequately supporting the use El El El of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? Discussion ai) No Impact. The site is located in a seismically-active region of California that is part of the Coast Ranges geomorphic province. This region is characterized by northNvest trending vallevs and mountain ranges running subparallel to the San Andreas Fault Zone. The closest active fault to the project site is the San Andreas fault Nvhich is located approximately 7 miles to the southNvest(Jennings, 1994). The San Andreas fault and other regional active faults,including the Hai-N and and Calaveras faults,pose the greatest threat of significant damage in the Bay Area according to the USGS Working Group (USGS, 2003). These three faults exhibit strike-slip orientation and have experienced movement Nvithin the last 150 vears.2 2 A strike-slip fault is a fault on which movement is parallel to the fault's strike or lateral expression at the surface. Blue Line Biogenic CNG Facility 36 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration The Alquist-Priolo Earthquake Fault Zoning Act requires the delineation of zones by the California Department of Conservation, Geological Survey (CGS,formerly knoN-,n as the California Division of Mines and Geology [CDMG]) along sufficiently active and Nvell- defined faults.' The purpose of the Act is to restrict construction of structures intended for human occupancy along traces of knovm active faults.Alquist-Priolo Zones are designated areas most likely to experience surface fault rupture,although fault rupture is not necessarily restricted to those specifically zoned areas. The project site is not located in an Alquist- Priolo Earthquake Fault Zone nor is it located on or immediately adjacent to an active or potentially active fault. The active faults nearest to the project site are the San Andreas, located approximately 7 miles southNvest of the project site, and the Hayvmrd,located approximately 15 miles northeast. As the project site is not located in an Alquist-Priolo Earthquake Fault Zone and is not located on or immediately adjacent to an active fault, there Nvould be no impact related to fault rupture hazards. an, aiii)Less than Significant. The project site is located in a seismically-active region. Recent studies by the United States Geological Survey (USGS) indicate there is a 63 percent likelihood of a Richter magnitude 6.7 or higher earthquake occurring in the Bay Area in the next 30 Nears(USGS,2008).The project site could experience a range of ground shaking effects during an earthquake on one of the aforementioned Bay Area faults.Depending on a variety of factors such as distance to the epicenter,magnitude of the event,and behavior of underlying materials,ground shaking could be significant. Seismic shaking of this intensity can also trigger ground failures caused by liquefaction,potentially resulting in foundation damage, disruption of utility service and roadway damage.' The project site is generally underlain by fill materials ranging in depths from 27 to 51 feet(Treadwell and Rollo, 1998). Beneath the fill materials,the site is underlain by Bay Mud deposits which extend to at least 80 feet below ground surface. Liquefaction potential is generally highest in loose saturated sediments in the upper 50 feet. Based on the proximity of the site to the Bay,groundNvater is likely encountered above 50 feet.During the geotechnical investigation conducted for previous improvements at the site,the saturated sand deposits below the groundNvater Nvere found to be relatively dense and contain clay,making the potential for liquefaction low. HoNvever, localized discontinuous sand deposits Nvere also encountered that may be susceptible to liquefaction. The proposed project Nvould not include the construction of any habitable structures.Although seismic ground shaking or liquefaction may occur at the site,the potential damage Nvould 3 An active fault is defined by the State of California is a fault that has had surface displacement within Holocene time (approximately the last 11.000 years).A potentially active fault is defined as a fault that has shown evidence of surface displacement during the Quaternary(last 1.6 million vears),unless direct geologic evidence demonstrates inactivity for all of the Holocene or longer. This definition does not,of course,mean that faults lacking evidence of surface displacement are necessarily inactive. Sufficiently active is also used to describe a fault if there is some evidence that Holocene displacement occurred on one or more of its segments or branches(Hart. 1997). 4 Shaking intensity is a measure of ground shaking effects at a particular location,and can vary depending on the overall magnitude of the earthquake,distance to the fault,focus of earthquake energy,and type of underlying geologic material.The Modified Mercalli(MM)intensity scale is commonly used to measure earthquake effects due to ground shaking. The MM values for intensitv range from I(earthquake not felt)to X11(damage nearly total). Liquefaction is the process by which saturated,loose,fine-grained,granular,soil,like sand,behaves like a dense fluid when subjected to prolonged shaking during an earthquake. Blue Line Biogenic CNG Facility 37 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility likely be minimized through the implementation of building code requirements. Project improvements Nvould be required to adhere to the most current version of the California Building Code,which includes specifications and seismic design criteria that are created to minimize damage from anticipated ground shaking and secondary*effects of liquefaction. Incorporation of the design criteria into project construction Nvould limit the potential damage to less than significant levels. a.iv) No Impact. The project site has a relatively*level topography*, especially*in the area of the proposed improvements,that Nvould not be subject to slope failure. In addition,there are no adjacent slopes that could affect the project site. Therefore,the proposed project Nvould not be adversely*affected by potential impacts associated Nvith seismically*induced landslides. b) Less than Significant. Due to past development activity*,the project site is underlain by fill materials and no longer contains native topsoils. Construction activities for the proposed project Nvould be relatively*minimal based on the use of modular technologies incorporated into the design. Construction is anticipated to disturb an area of approximately*0.44 acres and Nvould export approximately*2,230 cubic yards of material during preliminary*earthwork and grading. The relatively*small area of disturbance combined Nvith the relatively*short period of construction Nvould result in a less than significant potential for erosion. Therefore, considering the existing conditions and the relatively*minor area of disturbance,the potential for substantial soil erosion or loss of topsoil is considered less than significant. C) Less than Significant. As stated above,the project site is underlain by fill materials to a depth of 27 to 51 feet. Beneath the fill materials Bay Mud deposits are encountered which are typically characterized as soft compressible materials. However, the geotechnical investigation prepared for an earlier project at the site concluded that the fill materials Nvere relatively*dense. The proposed modular improvements likely*represent a relatively* light loading as compared to a multi-storied structure.Regardless,the proposed improvements Nvould be required to adhere to the requirements of the most recent version of the California Building Code, which includes specifications for site preparations such as compaction requirements for foundations. Therefore,Nvith incorporation of building code requirements and oversight of earthNvork activities by a California licensed geotechnical engineer,the potential impacts associated Nvith unstable soils Nvould be less than significant. Potential impacts related to liquefaction are discussed under Comment to 6.a.11, above. d) Less than Significant. As noted above,the project site is underlain by artificial fill. The geotechnical characteristics of this fill,including its potential for expansion,is currently* unknown. HoNvever,the proposed project Nvould be required to perform a design level geotechnical investigation in accordance Nvith the California Building Code,which includes requirements to identifi-foundation soils that could be affected by expansive soils.Therefore, Nvith implementation of recommendations made by a licensed geotechnical engineer in accordance Nvith current building code standards there Nvould be a less than significant impact related to expansive soils. Blue Line Biogenic CNG Facility 38 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration e) No Impact. The proposed project does not require the use of septic tanks or any other alternative wastewater disposal system. Therefore,the project Nvould have no impact related to the support of septic systems. References Jennings, C.

Discussion a-b) Less than Significant.GHG impacts are considered to be exclusively cumulative impacts; there are no non-cumulative GHG emission impacts from a climate change perspective (CAPCOA,2008).Construction and operational GHG emissions Nvere calculated,as described above in the Air Quality(Section 3)analysis. GHGs Nvould be generated during construction from the use of equipment, construction-related vehicular activity, and construction Nvorker automobile trips. The proposed project Nvould generate GHG emissions from operations through the folloN ing sources: on-road mobile,a front end loader,microturbine energy generation, grid electricity,lean gas flare, and composting (trace methane per SCAQMD composting emission factor [SCAQMD, 2001]). As described in the Air Quality analysis,this analysis adopts the thresholds and methodologies (as deemed appropriate for this project)from the BAAQMD CEQA Air Qzlality G idelines (BAAQMD, 2011) to determine the potential impacts of the project. The BAAQMD Guidelines do not include a specific threshold or methodology for assessing construction- related GHG emissions for CEQA analysis. In regards to operations,the previously adopted BAAQMD threshold for stationary-source projects of 10,000 MT COze%Tr Nvas applied to the project since the majont<T of GHG emissions Nvould be from stationary*sources. Stationary- source projects include land uses that Nvould accommodate processes and equipment that emit GHG emissions and Nvould require a BAAQMD permit to operate. GHG emissions associated Nvith the construction phase of the project Nvould result in a maximum annual generation of 62 metric tons of COze per Near(MT COze/vr),as shown in Appendix B.In addition,Table 3 presents an unmitigated estimate of the project's operational COze emissions. Data in Table 3 indicate that GHG emissions that Nvould result from the project Nvould not exceed the 10,000 metric tons per year threshold and Nvould be less than significant without mitigation.

No a. Assumptions and specific emission factors are included in Appendix B. Furthermore, as described in the updated information for the CEC grant,there are several GHG avoidance benefits to the project not included in the above estimate (Edgar and Associates,2012a). Specifically Nvith the 10,000 tons per Near throughput of the project,the fuel carbon intensity Nvould be 30.46g COze/MJ,Nvhich Nvould be approximately 68%less than diesel fuel and Nvould represent a GHG reduction relative to diesel of 387 MT COze/vr. In addition, assuming the food Nvaste input fraction is diverted from landfill disposal,then landfill gas emissions Nvould be eliminated for these materialS.6 This represents GHG emissions avoidance from 818 MT COze%Tr(if the landfill gas is used to generate electricit�T)to 1,351 MT COze/vr(if the landfill gas is flared). Finally, by using the food Nvaste digestate as compost7, the resulting compost emissions reduction Nvould be 377 MT COze/vr. Thus, implementation of the project would result in avoided GHGs of approximately 1,582 MT COze/vr up to 2,115 MT COze/vr. Finally,the project Nvould assist Nvith the goals and objectives of multiple plans and directives described in the Project Description, such as AB 32(Measures E-3 and RW-3), the LCFS, and the Ca1Recycle Strategic Directive 6.1. The project Nvould not conflict Nvith any applicable plans,policies, or regulations adopted for the purpose of reducing GHG emissions. This Nvould be a less than significant impact. 6 Yard waste is largely diverted already and was not included in the calculation. 7 Yard waste is assumed to be diverted and used as a soil amendment under existing conditions.

Discussion a, b) Less than Significant with Mitigation.Construction activities Nvould likely require the use of limited quantities of hazardous materials such as fuels,oils,lubricants,and solvents.The improper use,storage,handling,transport or disposal of hazardous materials during construction could result in an accidental release exposing construction workers,the public and the environment,including soil and/or ground or surface Nvater, to adverse effects. HoNvever,numerous laws and regulations govern the transport,use, storage,handling and disposal of hazardous materials to reduce the potential hazards associated N ith these activities. Cal/OSHA is responsible for developing and enforcing Nvorlcplace safety standards,including the handling and use of hazardous materials. Transportation of hazardous materials is regulated by the DOT and Caltrans. Together,federal and State agencies determine driver- Blue Line Biogenic CNG Facility 43 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility training requirements,load labeling procedures,and container specifications designed to minimize the risk of accidental release.In addition,the use of the modular design Nvould likely result in a relatively minor amount of hazardous materials that Nvould be required on site during construction. Therefore,the transport,use, storage,handling and disposal of hazardous materials Nvould be adequately controlled through existing regulatory*requirements and the potential impact during construction Nvould be less than significant. Operation and maintenance of the anaerobic digester facilities Nvould also involve the transport, use,storage and disposal of small quantities of hazardous materials such as fuels,lubricants, hvdraulic fluids.Handling of hazardous materials is covered by federal and State laws which minimize Nvorker safety*risks from both physical and chemical hazards in the Nvorkplace. Cal/OSHA is responsible for developing and enforcing Nvork.place safety*standards,including the handling and use of hazardous materials. Businesses that use hazardous materials are required to submit a Hazardous Materials Business Plan to the local CUPA,which performs inspections to ensure compliance N ith hazardous materials labeling,training,and storage regulations. For example,hazardous materials must be stored in containers according to the manufacturer's guidelines and appropriately*labeled. The Material Safety*Data Sheet for each chemical must be available for review. Employers must inform Nvorkers of the hazards associated N ith the materials they*handle and maintain records documenting training. As an existing facility*Nvith current use of hazardous materials,the Hazardous Materials Business Plan Nvould be required to be updated to reflect any changes that might occur from the proposed project. Transportation of hazardous materials is regulated by the DOT and Caltrans. Together, federal and State agencies determine driver-training requirements,load labeling procedures, and container specifications designed to minimize the risk of accidental release. The proposed project also involves the production of biogas generated through the anaerobic digestion process. Biogas is composed primarily*of methane but can also contain small quantities of carbon dioxide and hydrogen sulfide. The biogas Nvould be captured and the low quality*lean gas (methane content below 20%and higher than 1%)Nvould be destroyed in an enclosed lean gas flare (LGF) generated during digester termination operations. Methane is not toxic,but handling methane can be hazardous as it is ignitable and can be flammable. Methane has an ignition temperature of 1,000 degrees Fahrenheit(°F) and is flammable at concentrations bettveen 5 percent and 15 percent in air.Unconfined mixtures of methane in air are not explosive;however,a flammable concentration Nvithin an enclosed space in the presence of an ignition source can explode. Methane is buoyant at atmospheric temperatures and disperses rapidly*in air. Unintentional releases of biogas from the facility* could pose risks to human health and safety*.For example,biogas could be released from a leak.or rupture at the digester facility*. If the gas reaches a combustible mixture and an ignition source is present, a fire and/or explosion could occur,resulting in possible injuries and/or deaths. Blue Line Biogenic CNG Facility 44 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration Compliance Nvith existing safety regulations and Nvidely-accepted industry*standards Nvould minimize the hazard to the public and the environment. With respect to the flaring of biogas and potential fire hazards associated Nvith the storage and transport of methane and small quantities of other materials used in operations,the National Fire Protection Association(NFPA)has established standards for fire protection which Nvould be applicable to the construction of the AD facilities.These standards have been successfully*implemented by numerous Nvaste Nvater treatment facilities across the country*. Construction and operation of the project Nvould be required to comply*Nvith the California fire code and local building codes (including requirements for the installation of fire suppression systems). Standard safety measures for anaerobic treatment facility*construction and operation that Nvould minimize the potential for risks from unintentional releases of biogas include leak detection systems,warning signals,and safety*flares to reduce excess gas capacity*. If released to the environment,methane Nvould be dispersed rapidly*in air,minimizing the hazards of exposure. Although compliance Nvith existing laws and regulations governing the transport,use, storage, handling and disposal of hazardous materials Nvould likely*ensure less than significant impacts,a Fire Safety*Plan Nvould be implemented per Mitigation Measure HAZ-1 due to the combustion potential of methane. Mitigation Measure HAZ-1: Prior to project approval,the applicant shall prepare and implement a Fire Safety*Plan that outlines fire hazards, describes facility* operations procedures to prevent ignition of fires,requires regular inspection of fire suppression systems, and provides Nvorker training in safety*procedures as Nvell as protocols for responding to fire incidents. The Fire Safety*Plan shall be revieNved and approved by the local fire enforcement agency*. C) No Impact. As discussed above, small quantities of hazardous materials could be used in the construction and operation of the proposed project. Compliance Nvith environmental laws and regulations Nvould reduce the potential for any release of those materials to adversely*affect onsite Nvorkers,the environment or the public. There are no schools located Nvithin a quarter mile of the proposed project. Therefore,there Nvould be no impact related to potential exposure of hazardous emissions or acutely*hazardous materials, substances, or Nvastes Nvithin one-quarter mile of a school. d) Less than Significant. The project site is not included on the databases maintained by the Department of Toxic Substances Control(Envirostor)and the State Water Resources Control Board (Geotracker) (DTSC, 2012 and SWRCB, 2012). There is a database entry* for the project site address Nvhich addresses the adjacent former Fuller O'Brien Paint site. Dischargers from the adjacent facility*have impacted the nearby*channel Nvith questionable fill. Both parties involved are Nvorking together to cleanup the channel. The Fuller O'Brien Paint site Nvas created in the late 1960's and early* 1970's by filling the former San Bruno Shipping Channel. It is currently*a lovAving, 2-acre slough area located near the end of East Jamie Court. Multiple environmental investigations have been conducted on the property*since the 1980's. Elevated concentrations of lead are present in shallow sediment. Additionally*, semi-volatile organic compounds,similar to those found in asphalt, have also been encountered in fill sediments (SWRCB, 2012). Blue Line Biogenic CNG Facility 45 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility In addition, several properties located north of the project site are also associated Nvith the former Fuller O'Brien Paint facilities which have been subject to numerous soil and groundwater investigations (DTSC, 2012). The main hazardous Nvaste and hazardous waste constituent of concern Nvas lead; other constituents Nvere metals, VOCs, and semi- volatile compounds. The entire property's groundwater investigation Nvas documented in the 2005 RCRA Facility Investigation (RFI), which determined no further action Nvas necessary.Therefore,there is little evidence to suggest that the minimal earthNvork activities that Nvould be associated Nvith the proposed project Nvould encounter an-T contamination that resulted from neighboring properties and the potential impact Nvould be less than significant. e) No Impact. The proposed project is located approximately 8,200 feet north of Runwa-,T IOL-28R at San Francisco International Airport.The,San Mateo County Comprehensive Land Use Plan, published by the C/CAG in December 1996,is the official airport land use compatibility plan (ALUCP) for San Francisco International Airport. Based on a review of the S'an Mateo County Comprehensive Land Use Plan (1996 CLUP)it is noted that the proposed project site is Nvithin the community noise equivalent level(CNEL) 70 decibel (dBA)noise exposure contour for San Francisco International Airport.While the 1996 CLUP does not specifically define the extents of the AIA for San Francisco International Airport, it is assumed that the project site is Nvithin the AIA since the project site is located within the CNEL 70 dB noise exposure contour defined in the CLUP.While specific safety zones for San Francisco International Airport are not defined in the 1996 CLUP,the CLUP specifies that land uses Nvith certain characteristics could represent a hazard to safe air navigation in the vicinit-,T of San Francisco International Airport. These characteristics include, but are not limited to: (1)land uses that generate smoke or rising columns of air, and(2)land uses Nvithin approach and climb out areas that attract large concentrations of birds. The proposed AD facility is not expected to generate measurable amounts of smoke or steam and Nvould not attract large concentrations of Nsldlife(birds)that might pose a hazard to safe air navigation. The C/CAG Board generally reviews local land use actions/projects located Nvithin the AIA when there is a potential issue of compatibility Nvith airport activities at San Francisco International Airport. Based on a review of policies contained in the 1996 CLUP,the project Nvould not result in actions that Nvould conflict Nvith the ALUCP. Code of Federal Regulations, Title 14,Part 77,,S'afe Efficient Use and Preservation of the Navigable Airspace (14 CFR Part 77)establishes the federal review process for determining whether proposed development activities in the vicinity of an airport have the potential to result in a hazard to air navigation. 14 CFR Part 77 identifies criteria that govern which projects require notice to be fled Nvith the Federal Aviation Administration(FAA)as Nvell as identiA-ing standards for determining whether a proposed project Nvould represent an obstruction"that may affect safe and efficient use of navigable airspace and the operation of planned or existing air navigation and communication facilities". Objects that are identified as obstructions based on these standards are presumed to be hazards until an aeronautical studv conducted by the FAA determines othenvise. Blue Line Biogenic CNG Facility 46 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration The location of the proposed anaerobic digester Nvith respect to San Francisco International Airport warrants evaluation to determine if filing notice Nvith the FAA is required and whether proposed buildings and objects associated Nvith the proposed project could represent obstructions to air navigation based on the guidance contained in 14 CFR Part 77,Subpart C. 14 CFR Part 77.9 "Construction or Alteration Requiring Notice"indicates that notice must be fled Nvith the FAA for an-,T construction or alteration of objects Nsithin 20,000 feet of a public use airport runvmy when the height of the objects exceeds (i.e.,is taller than) an imaginary surface Nvith a 100:1 (1 foot upward per 100 feet horizontally) slope from the nearest point of the nearest runvmy. This requirement applies when the airport has at least one runvmv that exceeds 3,200 feet in length;for shorter runways the notification surface has a 50:1 slope and extends 10,000 feet from the runvmy. The runvmys at San Francisco International Airport are more than 3,200 feet in length. The height of the FAA's Notification surface at the proposed project site is approximately 80 feet above ground level(AGL)given the distance between the site and runvmys at San Francisco International Airport and the ground elevation relative to mean sea level at both locations. The anaerobic digester building is expected to have a height of approximately 30 feet AGL. Since the proposed height of the anaerobic digester building and flare structure are loNver than the height of the FAA notification surface,the project sponsor does not need to file Form 7460-1, "Notice of Proposed Construction or Alteration"with the FAA. f) No Impact. There are no knoNsn private airstrips within two miles of the proposed project site. There Nvould be no impact related to private airstrips. g) Less than Significant.The proposed project Nvould not significantly interfere Nvith emergency response plans or evacuation plans. The proposed project Nvould not impede or require diversion of rescue vehicles or evacuation traffic in the event of a life-threatening emergency. The impact Nvould be less than significant. h) No Impact. The project site is located in a commercial area of South San Francisco. The project site is not located in the vicinity of a Nvildland area susceptible to Nvildland fires. No impact Nvould occur.

HYDROLOGY AND WATER QUALITY— Would the project: a) Violate any water quality standards or waste discharge requirements? b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level(e.g.,the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? c) Substantially alter the existing drainage pattern of a site or area through the alteration of the course of a stream or river,or by other means,in a manner that would result in substantial erosion or siltation on-or off-site? d) Substantially alter the existing drainage pattern of a site or area through the alteration of the course of a stream or river,or by other means,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 stormwater drainage systems or provide substantial additional sources of polluted runoff? f) Otherwise substantially degrade 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 that would impede or redirect flood flows? i) Expose people or structures to a significant risk of loss, injury or death involving flooding,including flooding as a result of the failure of a levee or dam? j) Expose people or structures to a significant risk of loss, injury or death involving inundation by seiche, tsunami,or mudflow? Discussion a, f) Less than Significant.The Clean Water Act(CWA)has nationally regulated the discharge of pollutants to waters of the U.S. from any point source since 1972. In 1987,amendments to the CWA added section 402(p)v hich established a frameN ork for regulating non-point source storm ater discharges under the National Pollutant Discharge Elimination System (NPDES). The NPDES storm water program,implemented by the State Water Resources Control Board(SWRCB),regulates storm N-eater discharges from construction sites that Blue Line Biogenic CNG Facility 48 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration disturb one or more acres of land,municipal separate storm systems (MS4s), and major industrial facilities. Under the NPDES permit requirements,the proposed project Nvould not be required to obtain a General Construction Activities NPDES permit but because it Nvould disturb more than 10,000 square feet it Nvould have to meet the permit requirements for MS4s. South San Francisco is a co-permitee for the Municipal Regional StormNvater Permit(R2-2009-0074)Nvhich Nvas adopted in 2009 and amended November 2011 If not managed appropriately,nonpoint-source pollutants could be transported Nvith stormNvater runoff that reaches San Francisco Bav Nvhich Nvould result in a significant impact.HoNvever, to reduce impacts, stormwater control/Low Impact Design(LID)measures Nvould be required as part of compliance Nvith RWQCB Municipal Regional StormNvater Permit Order No. 2009-0074 Provision C.3 (Provision C.3). As required by the permit,the project applicant Nvould incorporate LID strategies, such as stormwater reuse, onsite infiltration, and evapotranspiration as initial stormNvater management strategies. Secondary methods that could be incorporated Nvould include the use of natural, landscape based stormNvater treatment measures, as identified b�T Provision C.3. Stormwater treatment measures Nvould also be required in the final design plans in accordance Nvith the San Mateo Count-,TNvide Water Pollution Prevention Program C.3 StormNvater Technical Guidebook. The treatment BMPs Nvill be required to include one or more of the folloNving: bioretention areas (including bioretention svmles),flow-through planters,tree Nvell filters,vegetated buffer strips,infiltration trenches,extended detention basins,pervious paving,green roofs, and media filter. Therefore,Nvith adherence to the existing stormwater regulations,the proposed project Nvould have a less than significant impact on Nvater quality. b) No Impact. The proposed project, by design,Nvould have a net zero Nvater supply usage as Nvell as a net zero introduction of new impervious surfaces. Therefore,there Nvould be no impact related to groundNvater recharge or loNvering of any local groundNvater table levels. C) Less than Significant. The proposed project Nvould be located in the area of the site that is currentIv covered by asphalt and Nvould not othenvise alter the course of any stream or river.With implementation of C.3 requirements,as described above for criterion"a",drainage patterns could be altered through an increase in stormwater management features Nvhich promote infiltration onsite. Adherence to the NPDES requirements for post-construction management of stormwater Nvould also ensure that stormwater is controlled in a manner Nvhich does not result in substantial erosion or siltation in on-or off-site runoff Therefore, the potential impact related to erosion and siltation Nvould be less than significant. d) Less than Significant. As mentioned above,the proposed project Nvould not increase the amount of impervious surfaces at the project site. In addition, adherence to the Regional Municipal NPDES permit includes measures to ensure that onsite management of stormwater Blue Line Biogenic CNG Facility 49 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility runoff does not result in any onsite flooding. Therefore,the potential impact related to flooding on-or off-site from changes in drainage patterns Nvould be less than significant. e) Less than Significant. As mentioned above,the proposed project Nvould not increase the amount of impervious surfaces at the site and therefore Nvould not increase the amount of stormNvater runoff from the site. In addition, any LID features that Nvould be added to the stormwater management of the site as required by the C.3 regulations Nvould result in a reduction of stormNvater flows from the site. Therefore,the potential impact on existing or planned stormNvater drainage systems Nvould be less than significant. g) No Impact. The proposed project does not include any construction of housing or other residential units and therefore there Nvould be no impact related to this criterion. h) Less than Significant.Periodic flooding occurs in South San Francisco, but is generally confined to certain areas along Colma Creels. The project site is not located within the 100-year flood zone and only the Bay shoreline areas are subject to coastal wave action (South San Francisco, 2012). Although potential future levels of sea level rise are difficult to predict, the Association of Bay Area Governments (ABAG)has compiled mapping that indicates areas that could be inundated Linder two different sea level rise scenarios: 16 inch and 55 inch rises. The proposed project site would not be inundated Linder either scenario according to these modeled mapping tools (ABAG, 2012a). The proposed improvements are not located along the shoreline. Therefore, the potential impact related to flooding would be less than significant. i) No Impact. According to mapping compiled by ABAG,there are no dam inundation areas located anN,-Nvhere Nvithin South San Francisco,therefore there Nvould be no impact related to failure of a dam or levee (ABAG, 2012b). J) Less than Significant. The project site is located relatively near the Bay shoreline which is considered potentially susceptible to seiche Nvaves;however,there is no historical record of any occurring Nvithin the Bay. Tsunami waves have been observed in the Bay most recently from the 2011 Japanese Tsunami disaster.Wave nun-up in the South San Francisco shoreline is estimated at approximately 4.3 feet(mean sea level)for a tsunami with a 100-year recurrence and 6.0 feet (mean sea level)for a 500-year tsunami (South San Francisco, 2012). According to modeled inundation mapping compiled by ABAG,the project site would not be subject to inundation from a tsunami event(ABAG, 2012c). The project is relatively flat with no real sources of mudflow in the vicinity and therefore would not be considered susceptible to mudflows. In summary,the project would have a less than significant impact related to inundation from seiche, tsunami or mudflow.

LAND USE AND LAND USE PLANNING— Would the project: a) Physically divide an established community? b) Conflict with any applicable land use plan, policy,or regulation of an agency with jurisdiction over the project(including,but not limited to the general plan, specific plan, local coastal program,or zoning ordinance)adopted for the purpose of avoiding or mitigating an environmental effect? c) Conflict with any applicable habitat conservation plan ❑ ❑ ❑ or natural community conservation plan? Discussion a) No Impact. The project Nyould be located at an existing parking area at the Blue Line MRF site,Nyhich is currentIv designated Mixed Industrial in the most recent General Plan Land Use Diagram(City of South San Francisco,2011a)and Zoning DistrictMap(City of South San Francisco, 201 lb). As such,the project Nyould have no impact related to dividing an established community. b) No Impact. The project Nyould be located approximately 8,200 feet north of RunNya-T IOL-28R at San Francisco International Airport.The project site is Nsthin the Airport Influence Area(AIA) Area B for San Francisco International Airport and Nyithin the CNEL 70 dBA noise exposure contour for San Francisco International Airport as defined in the San Mateo County Comprehensive Land Use Plan (1996 CLUP), the adopted Airport Land Use Compatibility Plan for the airport. While the proposed anaerobic digester facility is not in conflict Nyith policies contained in the 1996 CLUP for San Francisco International Airport, proposed development actions Nsithin Area B of the AIA should be referred to the C1CAG Board for a determination of consistency Nyith the ALUCP if they involve construction of buildings or structures Nyith a height of 35 feet or more. Since the project Nyould not result in structures of 35 feet or more,the project would not conflict Nyith any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect. C) No Impact. The project site is not covered by a Habitat Conservation Plan or Natural Community Conservation Plan. Therefore,the project Nyould not result in impacts related to this criterion.

MINERAL RESOURCES—Would the project: a) Result in the loss of availability of a known mineral ❑ ❑ ❑ resource that would be of 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 general plan,specific plan or other land use plan? Discussion a-b) No Impact. The project Nvould be located at an existing parking area at the Blue Line MRF site and Nvould not affect availability of mineral resources,nor Nvould the project result in the loss of anv delineated,locallNT important mineral resource recovers- site. Therefore,no impact on mineral resources is anticipated.

Discussion a) Less than Significant with Mitigation.Background noise in the project area is predominated by noise generated from the Blue Line MRF facility and punctuated by discrete noise events associated Nsth the San Francisco International Airport(SFO).The project site is surrounded by industrial and business park land uses,which are not typically considered to be noise sensitive land uses.HoNvever,open space,in this case the Bay Trail,is considered moderately noise sensitive. The City of South San Francisco maintains an East of 101 Area Plan Ns th an area specific Noise Element(City of South San Francisco, 1994). This Area Plan Noise Element establishes noise policies for development in the East of 101 Area, an area of South San Francisco predominated by industry and commercial businesses. The primary policy that Nvould apply to the project is Policy NO-4: New development shall be designed so that the average noise level resulting from the new development does not exceed an Leq of 60 dBA at the nearest open space or recreational area. The City of South San Francisco also maintains a City--wide noise ordinance,which is an enforceable regulation that is directed primarily at fixed noise sources generated on City and privately oNsned property(City Code, Chapter 832). The noise ordinance specifies noise standards based on the duration of the noise event over a given hour period. These Blue Line Biogenic CNG Facility 55 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility noise standards are then made applicable to the areas of potential impact(those properties affected by the intrusive noise). For the surrounding business park land uses,the ordinance applies a noise level standard of 70 dBA for a cumulative period of more than 30 minutes in anv hour and an Lmax of 90 dBA. The City noise ordinance exempts construction noise from compliance Nvith noise standards if construction noise is generated beN,-een the hours of 8 a.m.and 8 p.m. on Nveekdays,9 a.m. and 8 p.m. on Saturday, and 10 a.m. and 6 p.m. on Sundays and holidays. Construction noise is alloNved outside of these hours if permitted by the City, alloNving the noise can meet additional specifications outlined in Section 8.32.050(d)(1) and(2). Construction Land uses surrounding the project site consist of business parks to the north(180 feet avm--) and Nvest(80 feet avmy),and the Bay Trail to the south(420 feet avmy).There is a vegetative parcel buffering the business park to the north from the project,and a noise attenuation rate of 7.5 dBA per doubling distance Nvas assumed accordingly for this land use.There is also an existing concrete Nvall on the Nvestem boundary of the Blue Line MRF site that Nvould reduce noise exposure for land uses Nvest of the project.There are also existing Blue Line MRF buildings in bettveen the project and the Ba-T Trail that Nvould reduce noise exposure from the project. Since the existing area Nvest and south of the project consists primarily of paved hard surfaces,the general noise attenuation rate is assumed to be 6 dBA per doubling distance(not including reductions from intervening structures). Table 4 shows typical noise levels during different construction stages. Excavation noise levels are 89 dBA at 50 feet,which when attenuated to the nearest land uses,Nvould expose the north business park,Nvest business park, and the Bay Trail to noise levels of 75 dBA, 85 dBA, and 71 dBA,respectively, during the loudest of construction activities that Nvould occur. This estimate does not include reductions due to intervening structures, which Nvould likely further reduce noise exposure by 3 to 5 dBA. HoNvever,these overall noise levels associated Nvith project construction Nvould pose a substantial increase over the short-term (2 to 3 month) duration of construction. Implementation of Mitigation Measure NOI-1 Nvould ensure that construction noise associated Nvith the project Nvould be less than significant.

SOURCE: Bolt,Beranek,and Newman,1971. Mitigation Measure NOI-I: The project applicant shall require construction contractors to implement the folloNying mitigation measures: • Consistent Nyith the City of South San Francisco Municipal Code, all noise generating construction activities shall be limited to betNyeen the hours of 8 a.m. and 8 p.m. on Nyeekdays, 9 a.m. and 8 p.m. on Saturday, and 10 a.m. and 6 p.m. on Sundays and holidays. Operations In regards to long-term operations,the surrounding land use that Nyould be exposed to the most noise Nyould be the existing business park to the Nyest of the project. The research campus to the north and the Bay Trail to the south Nyould be much further aNyayT and Nyould be partially screened by existing structures. The primary sources of noise during operations Nyould be collection trucks,a front end loader,and the microturbine.HoNyever, trucks already operate on the project area and Nyould not result in a noticeable change in the noise environment. In addition, the microturbine Nyould be enclosed and Nyould not exceed the Citv of South San Francisco noise standards of 70 dBA for a cumulative period of more than 30 minutes in any hour or Lmax of 90 dBA. The front end loader, hovyever,Nyould be a neNy noise source in the project area and could generate substantial noise during equipment usage. The front end loader Nyould move materials from the aeration bav to the anaerobic digesters, then to the compost enclosure,and transferred onto transport trucks.The applicant anticipates the loader Nyould be used 3.5 hours per day.Using the FHWA RoadNyayT Construction Noise Model(RCNM),the estimated noise exposure at the nearest building Nyest of the project Nyould be slightly less than 70 dBA Leq,Nyhich includes a 5 dBA reduction in noise by the existing noise Nyall on the Blue Line MRF property boundarN-8. Thus,the project Nyould not exceed the City of South San Francisco noise ordinance levels and Nyould be less than significant Nyithout mitigation. 8 The RCNM output is included as Appendix C. Blue Line Biogenic CNG Facility 57 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility b) Less than Significant.Vibration and ground-borne noise issues tend to occur when physically forceful or ground-penetrating equipment is utilized, such as pile drivers or Nvhere blasting is necessary.No such equipment or activities are required during construction or operations of the proposed project.Thus,the proposed project Nvould not generate significant groundborne vibration or groundborne noise impacts. Therefore, this impact is considered less than significant. C) Less than Significant. See the discussion regarding operation related noise for criterion "a"above. This Nvould be a less-than-significant impact. d) Less than Significant with Mitigation. As discussed in the "Construction" sub-section of criterion "a"above,the resulting impact Nvould be less than significant Nvith implementation of Mitigation Measure N0I-1. e) Less than Significant.As discussed previously,the project Nvould be located approximately 8,200 feet north of Runvmv IOL-28R at San Francisco International Airport.The project site is located Nvithin the CNEL 70 dBA noise contour projected for the airport as defined in the San Mateo County Comprehensive Land Use Plan (San Mateo County, 1996). The proposed project does not involve the development of noise-sensitive land uses and aircraft noise is not anticipated to negatively affect the employees that Nvould operate the anaerobic digester facility. Implementation of the proposed projects Nvould not increase the number of people exposed to excessive levels of aircraft noise. Project impacts Nvould be less than significant. f) No Impact. The project is not located Nvithin two miles of a private airstrip,therefore the project Nvould not expose people Nvorking in the area to excessive noise levels.No impact Nvould occur.

El El El Discussion a.i) Less than Significant.As described above in the Hazards and Hazardous Materials analysis, Nvith respect to the flaring of biogas and potential fire hazards associated Nvith the storage and transport of methane and small quantities of other materials used in operations,the NFPA has established standards for fire protection which Nvould be applicable to the construction of the proposed AD facilities. These standards have been successfully implemented by numerous Nvaste Nvater treatment facilities across the country*. Construction and operation of the project would be required to comply*Nvith the California fire code and local building codes (including requirements for the installation of fire suppression systems). Standard safety*measures for anaerobic treatment facility*construction and operation that Nvould minimize the potential for risks from unintentional releases of biogas include leak detection systems,Nvarning signals,and safety*flares to reduce excess gas capacity*. In addition,per Mitigation Measure HA-Z-1,a Fire Safety*Plan shall be reviewed and approved by the local fire enforcement agency*prior to project construction.As such,the project Nvould not increase the demand for fire services and Nvould result in a less than significant impact. a.ii) No Impact. The project Nvould have no effect on the provision of police services. a.111 No Impact.

Discussion a-b) Less than Significant. The project Nvould be located at the existing Blue Line MRF site. Although the project Nvould result in changing yardwaste pickup to a Nveekly cycle (three daily trucks)rather than the existing biNveekly cycle (two daily trucks),the project Nvould operate Nvithin the existing truck and tonnage permits for the Blue Line facility. The minimal increase in collection truck activity and employee trips Nvould result in a less than significant impact and Nvould not conflict Nvith an applicable plan,ordinance, or polio* pertaining to the circulation system,nor Nvould it conflict Nvith any congestion management program. C) No Impact. The proposed project is not anticipated to conflict Nvith the goals and policies of the adopted Airport Land Use Compatibility Plan for San Francisco International Airport or result in a change in air traffic patterns or traffic levels at San Francisco International Airport that Nvould result in substantial safety risks. d-e) No Impact. Since the project Nvould be located on a portion of the existing Blue Line MRF parking lot, adjacent to the boundary line of the Blue Line property,the proposed project Nvould not involve any hazardous design features or incompatible uses pertaining Blue Line Biogenic CNG Facility 62 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration to transportation. Similarly,the project Nvould not have any impact on emergency vehicle access to and circulation through the project area. The project would result in no impact. f) No Impact. The project Nvould not affect bicycle or pedestrian safety because it Nvould be located a substantial distance from the Bay Trail(about 420 feet awa-,T),Nvith the existing Blue Line MRF buildings and operations occurring in between.

Discussion a-e) Less than Significant. One of the advantages of dry AD technologies in comparison to Nvet AD technology is the limited requirement for process Nvater. Water is constantly introduced into the dry AD system via the organic Nvaste itself. HoNvever,throughout the course of Near,there may be periods Nvhen the incoming organic Nvaste material is dryer (summer)or Nvetter(Nvinter)than the annual average. Depending on the moisture content of the organic Nvaste processed in the dry digesters,there may be periods Nvhen additional percolate Nvater makeup is required (in the case of loNver moisture content feedstocks), or Nvhen excess percolate is generated (in the case of higher moisture content feedstocks). In either case, the project design Nvould reduce if not eliminate the need for additional Nvater from site Nvater Nvells and discharges of excess process Nvater to the Nvaste Nvater system and thus establish a closed-loop system. During periods of excess percolate resulting from higher moisture feedstocks,the sanitized percolate Nvould be removed and applied to composting operations to maintain proper moisture levels. Altematively, sanitized percolate can also be marketed to local agriculture or landscapers as compost tea, a high value liquid soil amendment. In either case,there Nvould be no need for discharges to the Nvaste Nvater system. Blue Line Biogenic CNG Facility 64 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Initial Study/Mitigation Negative Declaration With respect to operational periods when percolate makeup is required,potable Nvater can be used,but the preference Nvould be the application of rinsate or reclaimed Nvater,provided these alternatives contain no constituents which could potentially harm the percolate biology. In regards to stormwater,the project Nvould not include the construction of any additional impermeable surfaces and Nvould not generate any additional storm Nvater drainage.Therefore, implementation of the project Nvould result in no impact to these systems. f-g) No Impact.One of the primary goals of the project is the reduction of landfdled organics, which Nvould thus result in no impact to the landfill permitted capacity. In addition,the project Nvould be required to comply Nvith the Solid Waste Facility Permit(SWFP)issued by the LEA and Ca1Recycle for the project site. The only byproduct generated by the project Nvould be sent to a commercial compost facility, ultimately to be used as a soil amendment. Implementation of the project Nvould result in no impact. Blue Line Biogenic CNG Facility 65 ESA/120353 Initial Study and Mitigated Negative Declaration September 2012 Blue Line Biogenic CNG Facility Mandatory Findings of Significance Less Than Significant Potentially with Less Than Significant Mitigation Significant Issues(and Supporting Information Sources): Impact Incorporation Impact No Impact 18. MANDATORY FINDINGS OF SIGNIFICANCE— Would the project: a) 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) Have impacts that are individually limited,but cumulatively considerable?("Cumulatively considerable"means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects,the effects of other current projects,and the effects of probable future projects)? c) Have environmental effects that would cause substantial adverse effects on human beings,either directly or indirectly? Discussion a) No Impact. The project site is currently developed as a parking lot and the project Nvould not disturb anv new areas. Thus,the project Nvould not substantially degrade the quality of the environment,reduce habitat, or restrict the range of a rare or endangered plant or animal, or eliminate a plant or animal community. The project Nvould not affect any historic structures. b) Less than Significant. The project Nvould not have a cumulatively considerable impact on anv of the environmental factors discussed above. This Nvould result in a less than significant impact. C) Less than Significant. The project Nvould not result in impacts to human beings that Nvould result in substantial adverse effects on human beings, directly or indirectly.
