Subpart I – Electronics Manufacturing
This page provides resources for subpart I reporters, including implementation information as well as supporting documents for relevant rulemakings.
Summary
The Subpart I applies to any facility engaged in electronics manufacturing and that meets the Subpart I source category definition. The Subpart I source category may have a threshold reporting requirement depending on how a facility satisfies the reporting threshold specified at 40 CFR § 98.91.
