NORTHERN SONOMA COUNTY AIR POLLUTION CONTROL DISTRICT
RULE 210 - ENVIRONMENTAL ASSESSMENT
If the Control Officer determines that the application is for a project or a portion of a project for which another
public agency has already acted as the lead agency in compliance with the California Environmental Quality Act
of 1970 (CEQA), no further processing of environmental documents shall be required. The Control Officer shall then
follow the procedure set forth in Article XII of Appendix A to this regulation.
If the Control Officer determines that the application is for a project which does not fall within the above paragraph,
and the Control Officer determines that the project is ministerial, categorically exempt or will have no significant
effect on the environment, it shall be exempt from the requirements of CEQA. If the Control Officer determines
that such project is not ministerial, is not categorically exempt but that it may have a significant effect on
the environment, the Procedures for Environmental Impact Review as found in Appendix A to this regulation, shall
be followed. Other project reviews performed by the District may proceed concurrently with a detailed environmental
assessment, but no Authority to Construct may be issued by the Control Officer until completion and filing of the
Notice of Determination.
