  1. Open ecfr.gov/current/title-40/chapter-I/subchapter-C/part-60/subpart-AAA
  2. Confirm applicability via §60.530 ("Am I subject to this subpart?")
  3. Read the May 15, 2020 Step 2 limits: 2.0 g/hr weighted average under crib-wood test methods, or 2.5 g/hr under the cordwood alternative
  4. Verify against the specific appliance's certification test method (crib vs cordwood), since limits differ
  5. Check the eCFR "current as of" date stamp — this subpart is under active EPA Clean Air Act §111(b) review (see litigation-status route)
