Accessed <br />June 25, 2020. <br /> <br />Would the project: <br />a) Conflict with or obstruct implementation of the applicable air quality plan? <br />Less than significant impact with mitigation incorporated. To address regional air quality standards, <br />the BAAQMD has adopted several air quality policies and plans, the most recent is the 2017 Clean <br />Air Plan. The 2017 Clean Air Plan was adopted in April of 2017 and serves as the regional Air Quality <br />Plan (AQP) for the Air Basin for attaining federal ambient air quality standards. The primary goals of <br />the 2017 Clean Air Plan are to protect public health and protect the climate. The 2017 Clean Air Plan
