Revised SMP-30 Use Permit, Sunol Valley Aggregate Quarry Alameda County

Type NOP Notice of Preparation

Description The current Sunol Valley Aggregate Quarry is under operation on an approximately 323-acre site. The

quarry was approved for aggregate mining by the County in 1992 pursuant to Surface Mining

Permit-30 (SMP-30). Under this currently effective permit, quarry operations can continue through

year 2011. An adjacent 58-acre parcel has now become available, and the applicant seeks to revise

the SMP-30 permit to increase aggregate reserves by expanding and deepening the quarry pit, which

will ultimately be used for water storage. The proposed revised permit (the project) seeks to increase

the area under permit, deepen the excavation, extend the permit expiration date to 30 years after

approval, to add an on-site asphalt batch plant and a concrete batch plant, and to amend the

Reclamation Plan for the site.

3. The project would generate 1 to 49 peak hour trips assigned to a State highway facility, and the affected highway facilities are experiencing significant delay; unstable or forced traffic flow (LOS "E" or "F") conditions.

We recommend using the Department' s "Guide for the Preparation of Traffic Impact Studies " for determining which scenarios and methodologies to use in the analysis. The guide can be accessed from the following webpage: http://www. dot. ca. gov /hg/traffops/ developserv I operationalsystems/reports/tisguide. pdf

If the proposed project will not generate the amount of trips needed to meet the Department's trip generation thresholds, an explanation of how this conclusion was reached must be provided.

Encroachment Permit Any work or traffic control within the State ROW requires an encroachment pennit that is issued by the Department. Traffic-related mitigation measures will be incorporated into the construction plans during the encroachment permit process. See the following website link for more information: http://www.dot.ca.gov/hq/traffops/developserv/perrnits/

To apply for an encroachment permit, submit a completed encroachment permit application, environmental documentation, and five (5) sets of plans which clearly indicate State ROW to the address at the top ofthis letterhead, marked ATTN: Michael Condie, Mail Stop #5E.

Re: Notice of Preparation of an Environmental Impact Repmt for the Sunol Valley Aggregate Quarry Revised Surface Mining Permit-30 (SMP-30) in Alameda County

Dear Mr. Jensen:

Under the provision of Section 15082 ofthe CEQA guidelines, the San Francisco Public Utilities Commission (SFPUC) hereby submits comments on the October 25, 2011 Notice of Preparation for the Sunol Valley Aggregate Quarry Revised Surface Mining Perrnit-30 (SMP-30) Environmental Impact Report (EIR).

Land Uses. Additional land uses within the SMP-30 project site include the SFPUC Calaveras Substation, Pacific Gas & Electric (PG&E) buried gas line, and overhead powerlines. Additional surrounding land uses (not within the SMP-30 project site) include the PG&E Stmol Substation north of the project site, a Chevron liquid fuel pipeline, two SFPUC watershed keeper residences (only one is mentioned in the NOP)- one near Alameda East Portal and another on Andrade Road, and two private residences on Hanson Quarry property on Athenour Way. These land uses should be included in the draft EIR and analyzed for potential impacts with the proposed project. Also note that the SFPUC Chlorination Facility and the Sunol Valley Water Treatment Plant are separated by approximately 1.5 miles.

Project Description. The project description should specify ownership ofthe water transmission lines and overhead power lines that will need to be relocated. The project description should also describe the reclamation plan required by the SFPUC in detail including: finish grading and engineered levees to create a storage lake for the volume of water as directed by the SFPUC, and a schedule showing the completion of various phases of the project, including reclamation.

Slope Stability. An analysis of the potential slope instability associated with the updated reclamation plan needs to be included in the draft EIR. After the site is

fully excavated, the sides of the pit will be re-graded under the updated reclamation plan. The new slopes should be analyzed for stability under water storage conditions. The experience of East Bay Regional Park District (EBRPD) in the re-use of quarries for recreational lakes could be informative, as the instability of quarry slopes resulted in unstable (due to water saturation) and erosive shoreline areas.

Fire Hazards. The Emergency Response and Fire Hazards section of the draft EIR should include requirements in the Alameda Watershed Fire Management Element (August 1996) fotmd in Appendix A-1 of the SFPUC Alameda Watershed Management Plan. Please note the correct title for this plan is the "SFPUC Alameda Watershed Management Plan, April2001" not 2007 as cited on page 44 of the NOP.

Habitat Conservation Plan. The SF PUC Alameda Watershed HCP (A WHCP) is currently being developed by the SFPUC, Several draft chapters have been presented at public meetings and posted on the SFPUC's website (sfwater.org). The Public Draft A WHCP and EIRIEIS is scheduled to be completed in Fall 2012 and the Final AWHCP and EIR/EIS is expected to be completed by Spring 2013. The ElR should analyze potential conflicts with the SFPUC A WHCP.

Recreation. The Recreation section of the draft EIR should include a description ofthe future use of the site to include recreational trails (as described in the Reclamation Plan and in the project description on page nine of the NOP).

Biological Resources. The draft EIR should include a citation for the California tiger salamander sighting for the SFPUC WSIP project described on page 27 of theNOP.

The SFPUC appreciates the opportunity to comment on the Sunol Valley Aggregate Quarry Revised SMP-30 Notice of Preparation of an Environmental Impact Report. Please contact Karen Frye at 415-554-1652 if you have any questions about our comments.

November 15, 2011 Mr. Bruce Jensen, Senior Planner Alameda County Community Development Agency 224 W. Winton Avenue, Suite 110 Hayward, CA 94544 Re: Notice of Preparation of an EIR for Revised SMP-30 Mining Permit The Center for Biological Diversity and the Alameda Creek Alliance have read the Notice of Preparation of an Environmental Impact Report for the proposed Sunol Valley Aggregate Quarry Revised Surface Mining Permit SMP-30, and support the proposed amendments to the current SMP-30 permit to expand the footprint of the quarry, increase the depth of excavation, extend the expiration date for 30 years, and add additional ancillary uses at the site including an asphalt batch plant and a concrete plant. The proposed modifications to the existing SMP-30 mining permit were anticipated in a 2010 quarry lease agreement between Oliver de Silva, Inc. and the SFPUC and in a 2008 cooperative conservation agreement between Oliver de Silva, Inc., the Alameda Creek Alliance and the Center for Biological Diversity. We support Alameda County incorporating the conservation measures from the Conservation Plan for Sunol Quarry SMP-30, which our organizations signed with Oliver de Silva, Inc., into the revised SMP-30 project. These proposed conservation measures will significantly reduce any potential impacts of SMP-30 mining operations on native wildlife species and their habitats, provide further mitigation for unavoidable biological impacts, benefit special-status species and their habitats in the vicinity of the project, and allow future beneficial changes to the Apperson Quarry project (SMP-17). The avoidance, mitigation and conservation measures in the conservation plan represent a significant reduction of the potential biological impacts of mining operations at SMP-30 on native species and habitats, offer full and appropriate mitigation for unavoidable impacts, and provide additional conservation benefits that will help to restore Alameda Creek and improve habitat for native species in the vicinity of the projects. Specifically, the conservation plan will: provide funding for projects to help restore steelhead trout to Alameda Creek, including up to $2 million for fish passage projects at

the BART weir and inflatable rubber dams in lower Alameda Creek and up to $1 million for retrofitting the PG&E pipeline crossing in the Sunol Valley; re-vegetate stream banks and restore more natural stream function to enhance habitat quality along Alameda and San Antonio Creeks adjacent to the SMP-30 quarry; accommodate possible future public access trails through the area; and provide financial support for a SFPUC Sunol Valley Restoration Plan to study, stabilize and restore the Sunol Valley reach of Alameda Creek. Our organizations believe that implementation of the conservation measures in the conservation plan will fully addresses all potential species, vegetation, habitat and biological impacts of the Revised SMP-30 project. Sincerely,

Peter Galvin Conservation Director Center for Biological Diversity

Jeff Miller Director Alameda Creek Alliance

Emissions are based on an annual production rate of 250,000 cubic yards of concrete per year and the default composition of concrete batches shown in footnote (a) of AP 42 Table 11.12-2 (for one cubic yard or 4,024 lbs of concrete: 1,865 lbs of aggregate, 1,428 lbs of sand, 491 lbs of cement, 73 lbs of cement supplement, and 20 gallons of water). 2. Emission factor for PM10 is from Table 11.12-2 of AP 42 for controlled conditions. PM2.5 emissions are conservatively assumed to be equal to PM10 emissions. Emission factors are in units of pound of pollutant per ton of material unloaded. 3. Emission factor calculated using methodology described in Table A.3. 4. Emission factors for PM10 and PM2.5 are calculated using Equation 11.12-1 and Table 11.12-4 of AP 42, assuming project-specific wind speed (6.9 mph, based on BAAQMD Sunol met station #1904 data from 2005-2009, excluding 2007 due to lack of data) and moisture content of cement and cement supplement (conservatively assumed to be 1%).

Equipment list as provided by Oliver de Silva. 2. Load factor obtained from OFFROAD2011. 3. For equipment where that the engine tier level was known, CARB's tier standards (CARB 2011a) were used to estimate emissions. When the tier level of the engine was unknown, CARB's model for estimating emissions from offroad equipment, OFFROAD2011, was used to estimate emissions. 4. Year represents the calendar year used to estimate emissions from OFFROAD. 5. The equipment list provided by Oliver de Silva was mapped to equipment considered in OFFROAD2011. 6. Maximum Horsepower represents the bin of horsepowers in OFFROAD used to estimate emissions from this source. 7. When the tier level of an engine was known, the emission limit was assumed to be the emission factor of the equipment. When OFFROAD2011 was used to estimate emissions, emission factors were calculated from the model reported emission rates, taking into account the equipment age distribution and engine deterioration factor, using the following formula: EF = OFFROAD2011 Emissions [ton/day] / Activities [hr/day] / AvgHP / LF * C Where, Activities are total daily equipment hours as reported by OFFROAD. AvgHP is the average equipment horsepower used by OFFROAD. LF is the equipment load factor reported by OFFROAD. C is the conversion factor: 907,184.74 gram/ton 8. PM emissions in OFFROAD and reported by ARB were assumed to be PM10. PM2.5 emissions were assumed to be 92% of PM10 emissions, consistent with URBEMIS calculations (URBEMIS 2007). ROG and TOG emissions were calculated using USEPA conversion factors (USEPA 2003). References CARB. 2011a. CARB and USEPA Off-Road Compression-Ignition (Diesel) Engine Standards.

Mobile sources include employee commute, vendor delivery, and customer pickup and delivery trips. ENVIRON assumed a mix of LDA, LDT1, LDT2 and MDV for employee commute ("commute") trips and T7 Tractor trucks for vendor and customer ("truck") trips. Weighted emission factors for commute and truck trips were calculated based on ratios of VMT by vehicle class estimated by EMFAC2011 for Alameda County. Calendar year 2011 was assumed for the Baseline scenario. For the Project scenario, emission factors were calculated for calendar years 2013 through 2035, the last year EMFAC2011 estimates emissions, to take into account the emission reductions as a result of engine improvements with time and the ARB's On-Road Heavy-Duty Diesel Vehicles Regulation. The weighted emission factors by year were calculated using the emission factors in Table A.18 and the fleetmix in Table A.19. 2. ER: running emissions [lb] EFR: weighted running emission factor [g/mile]. A speed of 15 mph was used for onsite travel and a combination of all speeds for offsite travel. VMT: One-way trip lengths and Number of One-way Trips are presented in Tables A.20, A.22, and A.23. C: unit conversion factor. 3. EI: idling emissions [lb] EFI: vehicle idling emission factor [g/min]. Idling Time: ENVIRON assumed that only truck trips would contribute to idling emission, with two 5-minute idling period for each round-trip – one after arriving at the Project site, one prior to leaving the Project site. C: unit conversion factor. Sources: CARB. 2007. 2007 EMission FACtors (EMFAC) model. Available online at: http://www.arb.ca.gov/msei/onroad/latest_version.htm CARB. 2009.

Emissions for calendar year 2011 were assumed for the Baseline scenario. 2. Passenger vehicles (LDA, LDT1, LDT2, and MDV) were used to estimate worker commute emissions. To be conservative, all truck delivery and haul trips were assumed to be HHD trucks for idling emissions. To be conservatitve, emission factors for T7 Tractors, the vehicle class with the highest emission factors, were assumed for running emissions from truck trips, estimated with EMFAC2011. 3. Because diesel exhaust is more toxic than gasoline exhaust, all vehicles were conservatively assumed to be diesel fueled. 4. A speed of 15 mph was used for onsite travel and a combination of all speeds for offsite travel. 5. At the time of this analysis, idling emission factors for trucks associated with EMFAC2011 had not been released. Therefore, idling emission factors for trucks were obtained from EMFAC2007. 6. The SG Module in EMFAC2011 calculates emissions in units of tons/day and calculates daily VMT associated with these emissions. Running emission factors shown here are calculated using the daily emissions and daily VMT. Idling emission factors were obtained directly from EMFAC2007 emfac mode output. 7. The SG Module in EMFAC2011 estimates SOx emissions. SOx was assumed to be equal to SO2 for this analysis. Sources: CARB. EMFAC2007 Model. 2006.

1. Road surface silt content is based on AP 42 for paved roads (See Table 13.2.1-3 of AP-42). The silt loading on Calaveras Road north of the site is based on a default value for roadways with ADT between 500 and 5,000 vpd. The silt loading onsite is the mean value for quarry facilities. The loading on Calaveras Road next to the site is the quarry silt loading reduced by 11% for street sweeping (WGA 2006). 2. The average vehicle weight for Haul Trucks and Water Trucks is the estimated average weight of on-road trucks. This weight assumes trucks will be loaded in one direction and unloaded in the other. The average vehicle weight for Employee Vehicles is estimated based on the heaviest class of Light Duty Trucks (5750 pounds).3. Number of days with at least 0.01 inch precipitation is 70 days based on BAAQMD Permit Guidance (§11.5)4. One-way trip length is the distance of the on-site paved road, located at the entrance of the facility from Calaveras Road (approximately one tenth of a mile).5. Number of trips are based on data provided by Oliver de Silva. Haul Truck and Employee Vehicle trips are consistent with the number of trips presented in the mobile exhaust analysis. Water Truck trips are based on two one-way trips per hour of operation.

7. Number of trips are based on data provided by Oliver de Silva. Scraper, Loader, and Bobcat trips are based on 1.4 MM tons material to be harvested and moved each year in order to support the production of 1.2 MM tons aggregate. In addition, Scraper trips are based on six round-trips per hour, Loader trips are based on 12.5 tons per round-trip capacity and assuming all 1.4 MM tons of material will be moved by Loaders, and Bobcat trips are based on 2 tons per round-trip capacity and assuming one quarter of the total material will also be moved by Bobcats, and Blade trips are based on two round-trips per hour. Water Truck trip are based on two one-way trips per hour of operation. Haul Truck trips are consistent with the number of trips presented in the mobile exhaust analysis.

3. The mean vehicle weights for Scrapers and Loaders are estimated based on the following Caterpillar models: 657G (Scrapers), 988H (Loaders). The mean vehicle weight for Bobcats is the estimated median operating weight for the range of Bobcat models. The mean vehicle weight for Water Trucks and Haul Trucks is the estimated average weight of on-road trucks.

4. Number of days with at least 0.01 inch precipitation is 70 days based on BAAQMD Permit Guidance (§11.5).

5. Control efficiency from watering assumed to be 70% based on BAAQMD Permit Guidance (§11.2 and §11.5). Watering will take place once per hour.

6. One-way trip lengths for Scrapers, Water Truck, and Haul Trucks are based on estimates from site map. One-way trip length for Loaders and Bobcats were provided by Oliver de Silva, Inc. and is the distance between the stockpiles and the plants (400 feet).

1. The MDAQMD Mineral Guidance methodology for Wind Erosion from Stockpiles (Most Complex method) was used in place of AP 42 methodology (§13.2.5 Industrial Wind Erosion) because it allows for a material-specific calculation by incorporating the silt loading parameter for each storage pile, which was provided by Oliver de Silva, Inc. The use of AP 42 methodology would have required assumptions about material threshold friction velocity.

1. Road surface silt loading is based on AP 42 for paved roads (See Table 13.2.1-3 of AP-42). The silt loading on Calaveras Road north of the site is based on a default value for roadways with ADT between 500 and 5,000 vpd. The silt loading on Calaveras Road next to the site is assumed to be the lower bound for silt loading for paved roads at a quarry reduced by 26% for PM10 efficient sweeping. The lower bound was used because the traffic volume on this part of Calaveras Road is greater than an onsite road, and hence would have a lower silt loading. The silt loading onsite is the mean value for quarry facilities reduced by 26% for PM10 efficient street sweeping (WGA 2006).

6. Number of trips are based on data provided by Oliver de Silva. Scraper, Loader, and Bobcat trips are based on 3.4 MM tons material to be harvested and moved each year in order to support the production of 3 MM tons aggregate. In addition, Scraper trips are based on six round-trips per hour, Loader trips are based on 12.5 tons per round-trip capacity and assuming all 3.4 MM tons of material will be moved by Loaders, and Bobcat trips are based on 2 tons per round-trip capacity and assuming one quarter of the total material will also be moved by Bobcats. Water Truck trip are based on two one-way trips per hour of operation. Haul Truck trips are consistent with the number of trips presented in the mobile exhaust analysis.

Project

1. Surface material silt content for Loaders is the AP 42 default for sand and gravel processing material storage area. Surface material silt content for Scrapers, Haul Trucks, and Water Trucks are AP 42 default for sand and gravel processing plant road. See Table 13.2.2-1.2. The mean vehicle weights for Scrapers and Loaders are estimated based on the following Caterpillar models: 657G (Scrapers), 988H (Loaders). The mean vehicle weight for Bobcats is the estimated median operating weight for the range of Bobcat models. The mean vehicle weight for Water Trucks and Haul Trucks is the estimated average weight of on-road trucks.3. Number of days with at least 0.01 inch precipitation is 70 days based on BAAQMD Permit Guidance (§11.5).4. Control efficiency from watering assumed to be 70% based on BAAQMD Permit Guidance (§11.2 and §11.5). Watering will take place once per hour.5. One-way trip lengths for Scrapers, Water Truck, and Haul Trucks are based on estimates from site map. Project Phase II trip lengths are conservatively used since they are longer than Phase I trip lengths. All other parameters are the same. One-way trip length for Loaders and Bobcats were provided by Oliver de Silva, Inc. and is the distance between the stockpiles and the plants (400 feet).

1. The MDAQMD Mineral Guidance methodology for Wind Erosion from Stockpiles (Most Complex method) was used in place of AP 42 methodology (§13.2.5 Industrial Wind Erosion) because it allows for a material-specific calculation by incorporating the silt loading parameter for each storage pile, which was provided by Oliver de Silva, Inc. The use of AP 42 methodology would have required assumptions about material threshold friction velocity.

Notes:1. Data provided by Oliver de Silva based on construction needs.2. Obtained from OFFROAD2011.3. EF: emission factor [g/hp-hr]. The emission factors were back calculated from OFFROAD2011 modeled emission rates,

taking into account the equipment age distribution and engine deterioration factor, using the following formula:EF = OFFROAD Emissions [ton/year] / Activities [hr/year] / AvgHP / LF * Conversion Factor

Where,Activities are total yearly equipment hours.AvgHP is the average equipment horsepower used by OFFROAD.LF is the equipment load factor reported by OFFROAD.C is the conversion factor: 907,184.74 gram/ton

4. PM emissions in OFFROAD and reported by ARB were assumed to be PM10. PM2.5 emissions were assumed to be 92% of PM10 emissions, consistent with URBEMIS calculations (URBEMIS 2007). ROG and TOG emissions were calculated using USEPA conversion factors (USEPA 2003).

Notes:1. ENVIRON calculated emissions from OFFROAD equipment based on the following equation:

Annual Emissions = Σ(EF * HP * LF * Hr *C)EF: emission factor [g/hp-hr] as shown in Table B.2. HP: equipment horsepower. Equipment horsepower information that was provided by Oliver de Silva.LF: equipment load factor obtained from OFFROAD2011. Hr: equipment hours provided by Oliver de Silva, as shown in Table B.1 C: unit conversion factor.

2. Emissions shown here are emissions from the construction of one phase. ENVIRON assumed the same equipment list would be used to construct Phase I and Phase II. Therefore, if both Phase I and Phase II are constructed in the same year, annual emissions shown here would be doubled and still be below thresholds. Daily emissions would remain the same, assuming the emissions and duration are linearly proportional.3. Average daily emissions are calculated assuming construction will occur over 80 days.

Notes:1. Source locations vary with the phase being considered. 2. Because exhaust and fugitive dust emissions would have different release characteristics, the emissions were modeled as separate sources. When a source has exhaust and fugitive dust emissions, the modeled sources occur at the same location, but have different release parameters. Fugitive dust concentrations are used to estimate chronic hazard index from crystalline silica.3. Equipment operating in each source was obtained from Oliver de Silva. 4. Large volume sources were modeled as smaller adjacent volume sources. The number of sources is the number of adjacent volume sources with the dimensions specified needed to cover the area of emissions.5. Dispersion of emissions was modeled using the χ/Q (“chi over q”) method, such that each phase had unit emission rates (i.e., 1 gram per second [g/s]), and the model estimates dispersion factors (with units of [ug/m3]/[g/s]). For volume sources, an unit emission rate is calculated as the inverse of the number of sources. For area sources, an unit emission rate is calculated as the inverse of the total area of the source.6. Release height of onroad vehicle emissions was determined based on information from previous CARB study (CARB 2000) and recommendations by ARB staff. Release height of off-road equipment was determined based on data provided for a similar source (ENVIRON 2009). Release height of fugitive dust sources was determined based on SCAQMD guidance (SCAQMD 2008), using volume sources instead of area sources for these mobile emissions.7. Initial vertical dimension for fugitive dust sources is consistent with SCAQMD guidance (SCAQMD 2008). For all other sources, the initial vertical dimension represents a elevated volume source not adjacent to a building, consistent with ISC guidance (USEPA 1995).8. Initial lateral dimension determined using ISC guidance (USEPA 1995).9. Area is the modeled area of the source, which was determined using aerial photographs.10. Release height for fugitive dust sources is consistent with SCAQMD guidance (SCAQMD 2008). Release height for plant operations were based on data from other similar plants and engineering judgement.11. Stack parameters were based on data from other similar plants and engineering judgment. 12. To take into account the effects of dispersion around the large stockpiles, the stockpiles were modeled as buildings in AERMOD. The height of the stockpiles was determined using aerial photographs and reasonable approximation. The area is consistent with the area of the fugitive dust emission source for the stockpiles.

Abbreviations: BAAQMD - Bay Area Air Quality Management District CEQA - California Environmental Quality Act HRA - health risk assessment USEPA - United States Environmental Protection Agency Notes: 1. The excess lifetime cancer risk assumes that an individual adjacent to the Project is exposed to all emissions. Cancer risks are estimated as the upper-bound incremental probability that an individual will develop cancer over a lifetime as a direct result of exposure to potential carcinogens. The estimated risk is expressed as a unitless probability. The cancer risks attributed to the emissions associated with the Project were calculated based on the exposure point concentration (C), the intake factors presented in Table C.2, the CPF, and the ASFs. Calculation: Riskinh = ΣRiskinh,i = ΣCi x MAFx CF x IFinh x CPFi x ASF Where: Riskinh = Cancer Risk; the incremental probability of an individual developing cancer as a result of inhalation exposure to a particular potential carcinogen (unitless) Riskinh,i = Cancer Risk for Chemical i Ci = Modeled Annual Average Concentration in air for Chemical i (µg/m3) MAF = Modeling Adjustment Factor CF = Conversion Factor (mg/µg) IFinh = Intake Factor for Inhalation (m3/kg-day) CPFi = Cancer Potency Factor for Chemical i (mg chemical/kg body weight-day) ASF = Age Sensitivity Factor 2. The amount of time the facility will operate in each configuration (Phase I and Phase II) is unknown at the time of this analysis. Therefore, to be conservative, the HRA was evaluated for Phase I and Phase II separately and both were compared against significance thresholds. 3. Exposure assumptions explained in Table C.2. School child represent children at the Sunol Glen Elementary School, and day care child represent children at the Eagle's Nest Childcare, which is within Sunol Glen Elementary School. 4.

Because Phase I and Phase II will not operate concurrently and will operate in different locations, to be conservative, the HRA was evaluated for Phase I and Phase II separately and both were compared against significance thresholds. 2. PM2.5 concentration shown here represents the concentration associated with the operational emissions of the entire facility. The MEISR identified for Phase I in this PM2.5 concentration analysis is located at UTMx = 598,430 m UTMy = 4,161,338 m. The MEISR identified for Phase II in this PM2.5 concentration analysis is located at UTMx = 598,959 m UTMy = 4,159,272 m. 3. The potential for exposure to result in chronic noncancer effects is evaluated by comparing the estimated annual average air concentration (which is equivalent to the average daily air concentration) to the chemical-specific noncancer chronic RELs presented in Table C.5. When calculated for a single chemical, the comparison yields a ratio termed a hazard quotient. The chronic HI is calculated by summing each hazard quotient. The MEISR identified for Phase I in this chronic analysis is located at UTMx = 598,959 m UTMy = 4,159,272 m. The MEISR identified for Phase II in this chronic analysis is located at UTMx = 600,137 m UTMy = 4,157,128 m. Calculation: Chronic HI = ΣChronic HQi = ΣCi / RELi Where: HI = Hazard Index HQi = Hazard Quotient for Chemical i Ci = Average Daily Air Concentration for Chemical i (µg/m3) RELi = Noncancer Reference Exposure Level for Chemical i (µg/m3) 4. ENVIRON evaluated the acute hazard indices (HIs) for the worst hourly operating scenarios of the entire facility. The potential for exposure to result in acute noncancer effects is evaluated by comparing the estimated maximum hourly air concentration to the chemical-specific noncancer acute RELs presented in Table C.5 When calculated for a single chemical, the comparison yields a ratio termed a hazard quotient. The acute HI is calculated by summing each hazard quotient. The MEISR identified for Phase I in this acute analysis is located at UTMx = 598,751 m UTMy = 4,159,182 m.

The MEISR identified for Phase II in this acute analysis is located at UTMx = 598,464 m UTMy = 4,158,859 m. Calculation: Acute HI = ΣAcute HQi = ΣCi / RELi Where: Acute HI = Acute Hazard Index Acute HQi = Acute Hazard Quotient for Chemical i Ci = Max hourly Air Concentration for Chemical i (µg/m3) RELi = Noncancer Reference Exposure Level for Chemical i (µg/m3) 5.

Notes:1. Chemicals listed here represent all toxic chemicals the Project was identified to emit. These chemicals were identified either with speciation profiles, or chemical specific emission factors for each source, as described in emission calculation tables.2. Concentrations and impacts shown in this table represent the estimated impacts of the Project on the MEISR located at UTMx = 598,959m, UTMy = 4,159,272m. See previous tables for explanation of and calculation details for Excess Lifetime Cancer Risk and Chronic Hazard Quotients. The Excess Lifetime Cancer Risk is calculated assuming a resident's lifetime exposure, with the appropriate CRAF. 3. A chemical's toxicity is consistent with Table C.5.4. DPM concentration from on-road sources is separated from other DPM because ARB's On-Road Heavy-Duty Diesel Vehicles Regulation forces emissions of DPM from trucks to be reduced in upcoming years (CARB 2011). To avoid overestimating impacts of the Project, emissions from on-road sources were estimated for each year and paired with the appropriate ASF and exposure. The 70-year average concentration represents the average concentration over a 70 year lifetime to be used in cancer risk calculations. Because the chronic HI is an annual standard, the maximum concentration from on-road diesel vehicles was found and used in the calculation of the chronic HI. This is shown in the Maximum Annual Average Concentration. DPM from all other sources , which are not assumed to change by year, are shown in the category from non-on-road sources.

Notes:1. There are two phases of construction for this project. Sources will operate in different areas depending on the phase.2. Due to lack of specific instructions on modeling of construction emissions from BAAQMD, ENVIRON used SCAQMD LST methodology and modeled construction sources as adjacent volume sources.3. The total area where emissions would occur for each source was determined using aerial photographs. This area was broken into adjacent volume sources consistent with LST methodology. 4. The number of sources was dicated by the source dimension and the area where emissions would occur.5. Dispersion of emissions was modeled using the χ/Q (“chi over q”) method, such that each phase had unit emission rates (i.e., 1 gram per second [g/s]), and the model estimates dispersion factors (with units of [ug/m3]/[g/s]). For volume sources, an unit emission rate is calculated as the inverse of the number of sources6. According to the LST methodology, release height of the modeled volume sources representing construction equipment was set to 5 meters.7. According to USEPA ISC3 User's Guide Volume II, initial lateral dimension of single volume sources is length of side divided by 4.3. 8. According to the LST methodology, initial vertical dimension of the modeled volume sources was set to 1.4 meters.

Notes:1. The excess lifetime cancer risk assumes that an individual adjacent to the Project is exposed to all emissions from construction equipment. Cancer risks are estimated as the upper-bound incremental probability that an individual will develop cancer over a lifetime as a direct result of exposure to potential carcinogens. The estimated risk is expressed as a unitless probability. The cancer risks attributed to the emissions associated with the Project were calculated based on the exposure point concentration (C), the intake factors presented in Table D.2, the CPF, and the ASFs. The major sources of construction emissions is diesel fueled equipment exhaust. Consistent with CARB guidance, risks are based on DPM concentrations from diesel-fueled equipment exhaust.Calculation:Riskinh = ΣRiskinh,i = ΣCi x MAF x CF x IFinh x CPFi x ASF

Where:Riskinh = Cancer Risk; the incremental probability of an individual developing cancer as a result of inhalation exposure to a

particular potential carcinogen (unitless)Riskinh,i = Cancer Risk for Chemical iCi = Modeled Annual Average Concentration in air for Chemical i (µg/m3)MAF = Modeling Adjustment FactorCF = Conversion Factor (mg/µg)IFinh = Intake Factor for Inhalation (m3/kg-day)CPFi = Cancer Potency Factor for Chemical i (mg chemical/kg body weight-day) ASF = Age Sensitivity Factor

2. Exposure assumptions explained in Table D.2. The maximally exposed resident from Project construction is located at UTMx = 598,958.8 m UTMy = 4,159,271.6 m. The day care child and school child is located at UTMx = 598,430 m UTMy = 4,161,337.6 m.3. Project risks represent the sum of Phase I and Phase II construction risks.

Notes:1. PM2.5 concentration shown here represents the concentration associated with the emissions from equipment used to construct the asphalt and concrete plants. The MEISR identified for PM2.5 is located at UTMx = 598,958 m UTMy = 4,159,272 m.

2. The potential for exposure to result in chronic noncancer effects is evaluated by comparing the estimated annual average air concentration (which is equivalent to the average daily air concentration) to the chemical-specific noncancer chronic RELs. When calculated for a single chemical, the comparison yields a ratio termed a hazard quotient. The hazard quotients were calculated based on the modeled annual average DPM concentrations from emissions from diesel fueled equipment and the chronic RELs presented in Table C.5. The MEISR identified for this chronic analysis is located at UTMx = 598,958 m UTMy = 4,159,272 m.Calculation:Chronic HI = ΣChronic HQi = ΣCi / RELi

Where:HI = Hazard IndexHQi = Hazard Quotient for Chemical i Ci = Average Daily Air Concentration for Chemical i (µg/m3)RELi = Noncancer Reference Exposure Level for Chemical i (µg/m3)

3. ENVIRON evaluated the acute hazard indices (HIs) for the worst hourly operating scenarios of diesel fueled construction equipment. The potential for exposure to result in acute noncancer effects is evaluated by comparing the estimated maximum hourly air concentration to the chemical-specific noncancer acute RELs presented in Table C.5. When calculated for a single chemical, the comparison yields a ratio termed a hazard quotient. The acute HI is calculated by summing each hazard quotient.

The MEISR identified for Phase I in this acute analysis is located at UTMx = 600,400 m UTMy = 4,158,450 m.The MEISR identified for Phase II in this acute analysis is located at UTMx = 600,600 m UTMy = 4,157,650 m.

Calculation:Acute HI = ΣAcute HQi = ΣCi / RELi

Where:Acute HI = Acute Hazard IndexAcute HQi = Acute Hazard Quotient for Chemical i Ci = Max hourly Air Concentration for Chemical i (µg/m3)RELi = Noncancer Reference Exposure Level for Chemical i (µg/m3)

4. Project represents the sum of PM2.5 concentration and chronic HI for Phase I and Phase II construction. This is a conservative estimate because construction of both Phase I and Phase II will not likely occur in the same year and would hence not be additive.

5. Acute impacts are not additive as phases 1 and 2 construction will not occur simultaneously.

All facilities within approximately 1,000 feet of the proposed project as per the BAAQMD's Stationary Source Screening Analysis Tool consistent with BAAQMD guidance. If a source was just further than 1,000 feet, and the address associated with the source is within 1,000 feet, the source was conservatively included here. Facility information obtained from the tool. Because the sources are approximately 7,500 feet from the Project's MEISR for cancer risk and chronic HI, the cancer risk and chronic HI from these sources were not evaluated here. 2. Approximate distance measured using an aerial map. Distance represents distance between the Project MEISR and the closest point where the source is expected to be, which is found through visual inspection of aerial maps. 3. The tool reports "Contact District Staff" for some sources. For these sources, the district was contacted to obtain health impact information and is indicated as "BAAQMD Inquiry" here. 4. BAAQMD provides a Cancer Risk and Chronic Hazard Index Distance Adjustment Multiplier for Diesel IC Engines to be used on long term health effects from diesel generators. If the source is known to be a diesel engine, the multiplier is applied to cancer risk, chronic HI, and PM2.5 concentration reported in the BAAQMD tool. BAAQMD also provides a Cancer Risk and Chronic Hazard Index Distance Adjustment Multiplier for Gasoline Dispensing Facilities to be used on long term health effects from gasoline dispensing facilities. The screening values provided by BAAQMD from gasoline dispensing facilities were scaled using the multiplier for cancer risk, chronic HI, and PM2.5 concentration. Sources: BAAQMD. 2011.

Major roadways, as defined by BAAQMD, identified in project area. 2. Distance measured using aerial maps. The cancer risk and chronic HI MEISR and PM2.5 concentration MEISR are in different locations. Impacts shown here are at the respective locations. 3. BAAQMD provides two screening tools for major roadways. One for highway risks and one for surface streets. The appropriate tool for each road was used here. 4. Average Daily Traffic for Calaveeras Road obtained from California Department of Public Health. To be conservative, the traffic volume was increased to a traffic volume for which BAAQMD estimates risks. Average Daily Traffic is not needed for I-680 as the BAAQMD tool reports health risks directly for each segment of a highway. 5. Health impacts calculated by interpolating reported impacts by distance and ADT as appropriate. 6. Surface streets tool reports that the chronic HI from any roadway would not exceed 0.03. To be conservative, 0.03 is used in this analysis. Sources: BAAQMD. 2011. Highway Screening Analysis Tool.

Notes:

1. CO2 emission factor is the average of 2006, 2007, and 2008 PG&E emission factors. The 2006 and 2007 PG&E emission factors are from the CARB LGOP, Table G.6 (the 2008 emission factor is not available in the LGOP). The 2008 emission factor is provided in PG&E's 2008 PUP Report.

Table A.1Electricity Emission Factors



2. CH4 and N2O emission factors are the average of 2006 and 2007 emission factors from the CARB LGOP, Table G.7.3. CO2e emissions include the sum of CO2 and CH4 emissions multiplied by their respective global warming potentials, as follows: CO2e = (CO2 x 1) + (CH4 x 21). Global warming potentials are from Appendix E of CARB's LGOP. As specified in the Protocol, the Intergovernmental Panel on Climate Change (IPCC)'s Second Assessment Report (SAR) global warming potentials are still used by international convention and in the United States, and are therefore used here.

USEPA. 1995. AP 42, Volume I, Fifth Edition. §11.1 Hot Mix Asphalt Plants.

1. Emission factor for CO2 is based on data provided by the anticipated vendor. Emission factor for CH4 is from AP 42 (§11.1, Tables 11.1-7 and 11.1-8), based on a low NOx natural gas heater rated at 2 MMBTU/hour and assuming the AP 42 natural gas heating value of 1,020 BTU/scf.2. Emission factors from AP 42 (§1.4, Table 1.4-2).3. Annual emissions are based on 1 MM tons per year asphalt production and 2,750 hours per year operation of the hot asphalt oil heater. CO2e emissions include the sum of CO2 and CH4 emissions multiplied by their respective global warming potentials, as follows: CO2e = (CO2 x 1) + (CH4 x 21) + (N2O x 310). Global warming potentials are from Appendix E of CARB's LGOP. As specified in the Protocol, the Intergovernmental Panel on Climate Change (IPCC)'s Second Assessment Report (SAR) global warming potentials are still used by international convention and in the United States, and are therefore used here.

Maximum Horsepower represents the bin of horsepowers in OFFROAD used to estimate emissions from this source.6. While OFFROAD2011 is the most recent version of ARB's emission estimator model for offroad equipment, the model does not estimate GHG emissions. Therefore, OFFROAD2007 was used to estimate GHG emissions associated with offroad equipment use. Emission factors were calculated from the model reported emission rates, taking into account the equipment age distribution and engine deterioration factor, using the following formula:

EF = OFFROAD2007 Emissions [ton/day] / Activities [hr/day] / AvgHP / LF * CWhere,

Activities are total daily equipment hours as reported by OFFROAD.AvgHP is the average equipment horsepower used by OFFROAD.LF is the equipment load factor reported by OFFROAD.C is the conversion factor: 907,184.74 gram/ton

Mobile sources include employee commute, vendor delivery, and customer pickup and delivery trips. ENVIRON assumed a mix of LDA, LDT1, LDT2 and MDV for employee commute ("commute") trips and T7 Tractor trucks for vendor and customer ("truck") trips. Weighted emission factors for commute and truck trips were calculated based on ratios of VMT by vehicle class estimated by EMFAC2011 for Alameda County. Calendar year 2011 was assumed for the Baseline scenario. For the Project scenario, emission factors were calculated for calendar years 2013 through 2035, the last year EMFAC2011 estimates emissions, to take into account the emission reductions as a result of engine improvements with time and the ARB's On-Road Heavy-Duty Diesel Vehicles Regulation. The weighted emission factors by year were calculated using the emission factors and fleetmix shows in table A.13 and A.14, respectively. 2. ER: running emissions [lb] EFR: weighted running emission factor [g/mile]. A speed of 15 mph was used for onsite travel and a combination of all speeds for offsite travel. VMT: One-way trip lengths and Number of One-way Trips are presented in Tables A.12, A.16, and A.17. C: unit conversion factor. 3. EI: idling emissions [lb] EFI: vehicle idling emission factor [g/min]. Idling Time: ENVIRON assumed that only truck trips would contribute to idling emission, with two 5-minute idling period for each round-trip – one after arriving at the Project site, one prior to leaving the Project site.

Emissions for calendar year 2011 were assumed for the Baseline scenario. 2. Passenger vehicles (LDA, LDT1, LDT2, and MDV) were used to estimate worker commute emissions. To be conservative, all truck delivery and haul trips were assumed to be HHD trucks for idling emissions. To be conservatitve, emission factors for T7 Tractors, the vehicle class with the highest emission factors, were assumed for running emissions from truck trips, estimated with EMFAC2011. 3. Because diesel exhaust is more toxic than gasoline exhaust, all vehicles were conservatively assumed to be diesel fueled, to be consistent with the air quality analysis. 4. A speed of 15 mph was used for onsite travel and a combination of all speeds for offsite travel. 5. At the time of this analysis, idling emission factors for trucks associated with EMFAC2011 had not been released. Therefore, idling emission factors for trucks were obtained from EMFAC2007. 6. The SG Module in EMFAC2011 calculates emissions in units of tons/day and calculates daily VMT associated with these emissions. Emission factors shown here are calculated using the daily emissions and daily VMT. References: ARB. EMFAC2007 Model. 2006.

Assessment Report (SAR) global warming potentials are still used by international

convention and in the United States, and are therefore used here.

Michelle Giolli Environmental Science Associates 350 Frank Ogawa Plaza Suite 300 Oakland, CA 94612

Subject: Species List for SMP 30

Dear: Ms. Giolli

We are sending this official species list in response to your November 2, 2011 request for information about endangered and threatened species. The list covers the California counties and/or U.S. Geological Survey 7½ minute quad or quads you requested.

Our database was developed primarily to assist Federal agencies that are consulting with us. Therefore, our lists include all of the sensitive species that have been found in a certain area and also ones that may be affected by projects in the area. For example, a fish may be on the list for a quad if it lives somewhere downstream from that quad. Birds are included even if they only migrate through an area. In other words, we include all of the species we want people to consider when they do something that affects the environment.

Please read Important Information About Your Species List (below). It explains how we made the list and describes your responsibilities under the Endangered Species Act.

Our database is constantly updated as species are proposed, listed and delisted. If you address proposed and candidate species in your planning, this should not be a problem. However, we recommend that you get an updated list every 90 days. That would be January 31, 2012.

Please contact us if your project may affect endangered or threatened species or if you have any questions about the attached list or your responsibilities under the Endangered Species Act. A list of Endangered Species Program contacts can be found at www.fws.gov/sacramento/es/branches.htm.

Important Information About Your Species List

How We Make Species Lists We store information about endangered and threatened species lists by U.S. Geological Survey 7½ minute quads. The United States is divided into these quads, which are about the size of San Francisco.

The animals on your species list are ones that occur within, or may be affected by projects within, the quads covered by the list.

Fish and other aquatic species appear on your list if they are in the same watershed as your quad or if water use in your quad might affect them.

Amphibians will be on the list for a quad or county if pesticides applied in that area may be carried to their habitat by air currents.

Birds are shown regardless of whether they are resident or migratory. Relevant birds on the county list should be considered regardless of whether they appear on a quad list.



Plants Any plants on your list are ones that have actually been observed in the area covered by the list. Plants may exist in an area without ever having been detected there. You can find out what's in the surrounding quads through the California Native Plant Society's online Inventory of Rare and Endangered Plants.

Surveying Some of the species on your list may not be affected by your project. A trained biologist and/or botanist, familiar with the habitat requirements of the species on your list, should determine whether they or habitats suitable for them may be affected by your project. We recommend that your surveys include any proposed and candidate species on your list. See our Protocol and Recovery Permits pages.

For plant surveys, we recommend using the Guidelines for Conducting and Reporting Botanical Inventories. The results of your surveys should be published in any environmental documents prepared for your project.

Your Responsibilities Under the Endangered Species Act All animals identified as listed above are fully protected under the Endangered Species Act of 1973, as amended. Section 9 of the Act and its implementing regulations prohibit the take of a federally listed wildlife species. Take is defined by the Act as "to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect" any such animal.

Take may include significant habitat modification or degradation where it actually kills or injures wildlife by significantly impairing essential behavioral patterns, including breeding, feeding, or shelter (50 CFR §17.3).

Take incidental to an otherwise lawful activity may be authorized by one of two procedures:

If a Federal agency is involved with the permitting, funding, or carrying out of a project that may result in take, then that agency must engage in a formal consultation with the Service.

During formal consultation, the Federal agency, the applicant and the Service work together to avoid or minimize the impact on listed species and their habitat. Such consultation would result in a biological opinion by the Service addressing the anticipated effect of the project on listed and proposed species. The opinion may authorize a limited level of incidental take.

If no Federal agency is involved with the project, and federally listed species may be taken as part of the project, then you, the applicant, should apply for an incidental take permit. The Service may issue such a permit if you submit a satisfactory conservation plan for the species that would be affected by your project.

Should your survey determine that federally listed or proposed species occur in the area and are likely to be affected by the project, we recommend that you work with this office and the California Department of Fish and Game to develop a plan that minimizes the project's direct and indirect impacts to listed species and compensates for project-related loss of habitat. You should include the plan in any environmental documents you file.

Critical Habitat When a species is listed as endangered or threatened, areas of habitat considered essential to its conservation may be designated as critical habitat. These areas may require special management considerations or protection. They provide needed space for growth and normal behavior; food, water, air, light, other nutritional or physiological requirements; cover or shelter; and sites for breeding, reproduction, rearing of offspring, germination or seed dispersal.



Although critical habitat may be designated on private or State lands, activities on these lands are not restricted unless there is Federal involvement in the activities or direct harm to listed wildlife.

If any species has proposed or designated critical habitat within a quad, there will be a separate line for this on the species list. Boundary descriptions of the critical habitat may be found in the Federal Register. The information is also reprinted in the Code of Federal Regulations (50 CFR 17.95). See our Map Room page.

Candidate Species We recommend that you address impacts to candidate species. We put plants and animals on our candidate list when we have enough scientific information to eventually propose them for listing as threatened or endangered. By considering these species early in your planning process you may be able to avoid the problems that could develop if one of these candidates was listed before the end of your project.

Species of Concern The Sacramento Fish & Wildlife Office no longer maintains a list of species of concern. However, various other agencies and organizations maintain lists of at-risk species. These lists provide essential information for land management planning and conservation efforts. More info

Wetlands If your project will impact wetlands, riparian habitat, or other jurisdictional waters as defined by section 404 of the Clean Water Act and/or section 10 of the Rivers and Harbors Act, you will need to obtain a permit from the U.S. Army Corps of Engineers. Impacts to wetland habitats require site specific mitigation and monitoring. For questions regarding wetlands, please contact Mark Littlefield of this office at (916) 414-6520.

Updates Our database is constantly updated as species are proposed, listed and delisted. If you address proposed and candidate species in your planning, this should not be a problem. However, we recommend that you get an updated list every 90 days. That would be January 31, 2012.

Manufactured Gas Plants: EDR Proprietary Manufactured Gas PlantsThe EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’sto produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixtureof coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compoundsare potentially hazardous to human health and the environment. The byproduct from this process was frequentlydisposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soiland groundwater contamination.
