Rule 360 Summary of Requirements

How do I know if a unit is certified?

A unit may be certified in one of three ways:

  1. It was certified in compliance with the previous limits of South Coast Air Quality Management District (SCAQMD) Rule 1146.2 and appeared on this previous list of certified units.
  2. It is certified in compliance with the current limits of South Coast Air Quality Management District (SCAQMD) Rule 1146.2 and appears on their current list of certified units.
  3. It is certified through the Santa Barbara County Air Pollution Control District and appears on our current list of certified units.

Any unit that is certified will also display its certification status on its permanent nameplate.

How do I certify a unit?

To certify a unit that is not currently listed as certified, you must have it tested by an independent testing company and submit a compliance report to the District for approval. Submit a completed Rule 360 Compliance Report Form -14 with a copy of the source test results to request certification.
