Summary

AP-42 is EPA's compilation of emission factor information, organized by source category chapters and sections. Sections are revised individually, so the revision date of each section matters. AirPermitHub will store each factor with its section, revision date, and rating.

Applicability

AP-42 is guidance, not a regulation. Permits and rules may require or allow other methods.
