Air Quality

SACOG partners with the air districts of the Sacramento Region in their efforts to develop a new State Implementation Plan (SIP) that will address the reality that the region will not comply with federal ozone standards by 2050 as mandated by the federal Clean Air Act. As part of the region's overall effort to meet clean air standards and achieve conformity with transportation plans, SACOG also partners with the air districts to promote clean-fuel vehicles and develop mobile source control measures through the Sacramento Emergency Clean Air and Transportation (SECAT) program.
