What emissions must be reported?
All sources must report annual emissions for regulated pollutants. This includes criteria pollutants and HAPs. For sources that emit HAPs, a HAP is to be reported only if there is a specific regulation (NESHAP or MACT) that applies to the source. For example, if your source is subject to the MACT for halogenated solvent cleaning. Emissions of the HAPs used in that solvent cleaning must be reported. Please note: Your permit may require you to report emissions of HAPs.
