Energy Usage Energy usage includes emissions from the generation of electricity and natural gas used on -site. Mobile Sources Mobile sources include the emissions from the vehicle miles generated by the project. The vehicle trips of the project were analyzed based on project trip generation in the traffic report. Solid Waste Waste includes the GHG emissions generated from the processing of solid waste from the project as well as the GHG emissions from the solid waste once it is hauled to a landfill. AB 341 requires that 75 percent of solid waste be diverted from landfills by 2020. Water Water includes the potable water that would be used by the residents and landscaping based on the GHG emissions associated with the energy used to filter and transport the water to the site. Construction The construction -related GHG emissions are based on a 30-year amortization rate as recommended by the SCAQMD GHG Working Group meeting on November 19, 2009. The construction -related GHG emissions were calculated by CalEEMod and are shown in Table 5 above. Project Greenhouse Gas Emissions The GHG emissions have been calculated based on the parameters described above for opening year 2022. A summary of the project's unmitigated GHG emissions are shown in Table 9. As shown, the subtotal for the project's emissions are calculated to be 2,598.20 MTCO2e per year. According to the above threshold of significance, a cumulative global climate change impact would potentially occur if the GHG emissions created from the on -going operations exceed the threshold of 3,000 metric tons per year of CO2e. As shown in Table 9, the project would not exceed the tier 3 SCAQMD draft screening threshold of 3,000 metric tons CO2e per year, therefore the project would not have a significant impact to global climate change. The project is also subject to the requirements of the California Green Building Standards Code. On January 12, 2010, the State Building Standards Commission unanimously adopted updates to the California Green Building Standards Code, which went into effect on January 1, 2011. The Code is a comprehensive and uniform regulatory code for all residential, commercial and school buildings. The California Green Building Standards Code does not prevent a local jurisdiction from adopting a more stringent code as state law provides methods for local enhancements. The Code recognizes that many jurisdictions have developed existing construction and demolition ordinances, and defers to them as the ruling guidance provided they provide a minimum 65 percent diversion requirement. The code also provides exemptions for areas not served by construction and demolition recycling infrastructure. State building code provides the minimum standard that buildings need to meet to be certified for occupancy. Enforcement is generally through the local building official.
