City of Pleasanton CEQA GHG Emissions Thresholds and Guidance pertaining to mandatory solar provisions.33 Online resources can be used to determine the amount of kilowatt-hours that would be generated per year by the required solar PV system.34 The energy reduction achieved by on-site PV solar panels should be included in CaIEEMod. Future updates to Title 24 as they relate to the Building Energy Efficiency Standards should be incorporated into CaIEEMod as applicable. Mobile Source Emissions CaIEEMod quantifies mobile source emissions generated by vehicle trips associated with the proposed plan/project. If available, plan/project-specific trip generation rates or VMT data should be input in CaIEEMod. Water and Wastewater Emissions The amount of water used, and the amount of wastewater generated by a plan/project generate indirect GHG emissions.These emissions are a result of the energy used to supply,convey, and treat water and wastewater. In addition to the indirect GHG emissions associated with energy use, the wastewater treatment process itself can directly emit both CH4 and N20. The indoor and outdoor water use consumption data for each land use subtype comes from the Pacific Institute's(2003) Waste Not, Want Not: The Potential for Urban Water Conservation in California.35 Based on that report, a percentage of total water consumption is dedicated to landscape irrigation,which is used to determine outdoor water use. Wastewater generation is similarly based on a reported percentage of total indoor water use. New development will be subject to the California Green Building Standards Code (CALGreen), which currently requires a 20 percent increase in indoor water use efficiency and the use of water- efficient irrigation systems.Thus, in order to account for compliance with CALGreen,a 20 percent reduction in indoor water use and the use of water-efficient irrigation systems should be included in the water consumption calculations for new residential, non-residential, and mixed-use development. Future updates to Title 24 as they relate to CALGreen water efficiency requirements should be incorporated into CaIEEMod as applicable. Solid Waste Emissions The disposal of solid waste produces GHG emissions from the transportation of waste, anaerobic decomposition in landfills, and incineration.To calculate the GHG emissions generated by solid waste disposal,the total volume of solid waste is calculated using waste disposal rates identified by CalRecycle.The methods for quantifying GHG emissions from solid waste are based on the IPCC method, using the degradable organic content of waste. CEQA document preparers should contact the City's Community Development Department to obtain the City's most recent solid rate diversion rate to be included in the calculation of solid waste GHG emissions. 33 In 2020,the City Council will consider adoption of the Clean Energy Choice Program for New Buildings,which may include solar requirements for other types of land uses. 34 Zientara,Ben.2019."How much electricity odes a solar panel produce?"Last updated:November 6,2019. https://www.soIa rpowerrocks.com/sola r-basics/how-m uch-electricity-does-a-sola r-panel-prod uce/. 35CAPCOA.2017.California Emissions Estimator Model User Guide:Version 2016.3.2.Prepared by BREEZE Software,A Division of Trinity Consultants in collaboration with South Coast Air Quality Management District and the California Air Districts. http://www.agmd.gDv/caleemod/user's-guide. 34
