4.0 Cumulative Analysis
weekday traffic in the area resulting from project development, including the Oro Bay Specific
Plan project. Therefore, implementing the General Plan, including constructing and operating the
headquarters facilities, would not result in a significant cumulative impact or contribute
considerably to a significant cumulative impact on traffic or transportation conditions.
4.4.2 Air Quality
Butte County AQMD’s Air Quality Handbook (Section 4) requires that a cumulative air quality
impact analysis be performed to evaluate the combined air quality impacts of this project and
impacts from existing and proposed future development within 1 mile of the project site. Butte
County AQMD recommends that projects determine their cumulative air quality impacts by
evaluating if the proposed project would be consistent with the Air Quality Attainment Plan
(AQAP), State Implementation Plan (SIP), or exceed Butte County AQMD thresholds even with
mitigation. Butte County AQMD has developed the following criteria to analyze if the proposed
project is consistent with the AQAP:
The project does not require a change in the existing land use designation, and projected
emissions of ROG and NOX from the proposed project are equal to or less than the
emissions anticipated for the site if developed under the existing land use designations.
The project does not exceed the “project alone” significance criteria.
The lead agency for the project requires the project to implement any applicable emission
reduction measures contained in and/or derived from the AQAP.
The project complies with all applicable district rules and regulations.
As discussed in Section 3.2, “Air Quality,” the criteria pollutants and TAC impacts associated with
construction of the Clay Pit SVRA General Plan would be temporary, would be intermittent, and
would cease following completion of the proposed structures/site modifications. In addition, these
impacts were determined to be less than significant. Due to the short‐term nature of these
impacts, it is not anticipated that implementing the General Plan, including constructing and
operating the headquarters facilities, would cause any cumulative construction impacts.
Therefore, implementing the General Plan would not cause a cumulatively considerable increase
in precursor emissions for a regional nonattainment pollutant, and this impact would be less than
significant.
Increased activity within Clay Pit SVRA, as envisioned by the General Plan, would result in
increased air emissions. Impacts resulting from implementation of the General Plan would occur
over many years because the Clay Pit SVRA General Plan provides guidance and vision for a period
of 20 years or more. For this reason, future conditions were analyzed for the year 2030. This
