1 The values presented do not include the full life cycle of the greenhouse gas (GHG) emissions. The GHG emissions
from producing and transporting the construction and maintenance materials used under the Clay Pit SVRA
General Plan, from solid waste that would be generated over the life of the project, or from end of life processes
(e.g., recycling of materials) that would occur as an indirect result of the project. Estimating the GHG emissions
associated with these processes would require analysis beyond the current state of the art in impact assessment
and may lead to a false or misleading level of precision in reporting operational GHG emissions. Furthermore,
indirect emissions associated with in‐state energy production and generation of solid waste would be regulated
under AB 32 directly at the source or facility that would handle these processes. The emissions associated with off‐
site facilities (e.g., for manufacturing plants, landfills) in California would be closely controlled, reported, capped,
and traded under AB 32 and California CARB programs, as recommended by CARB’s scoping plan (CARB 2008).
Therefore, it is assumed that GHG emissions associated with these life‐cycle stages would be consistent with AB 32
requirements.
2 Net decreases are shown in parenthesis.
3 Construction emissions were amortized over a 20‐year period and added to operational emissions per the
methodology recommended by SMAQMD (SMAQMD 2009).
4 Area source emissions include emissions associated with propane combustion for space and water heating.
5 Mobile source emissions estimated including California’s Pavley clean‐air standards and Low Carbon Fuel Standard.
6 Off‐road source emissions estimated including California’s Low Carbon Fuel Standard.
7 Existing maintenance operations would continue through 2030. No increase in maintenance activities is anticipated.
