Oppose Standards for Air Curtain Incinerators That Only Burn
Standards for Air Curtain Incinerators That Only Burn Wood Wastes, Yard Wastes and Clean Lumber; Provision for Commercial and Industrial Solid Waste Incineration Units: Temporary Use Incinerators and Air Curtain Incinerators Used in Disaster Recovery

The EPA's proposing two regulatory changes for air curtain incinerators (ACIs) and commercial/industrial solid waste incinerators (CISWIs) under the Clean Air Act. The first action would consolidate existing opacity and monitoring rules for ACIs that burn wood waste, yard waste, and clean lumber into a single subpart, and it'd remove permitting requirements for ACIs not at major sources. The second action would allow CISWI units to temporarily burn disaster debris without meeting normal CAA section 129 requirements, matching flexibility that already exists for other solid waste incinerators.

The U.S. Environmental Protection Agency (EPA) is proposing two separate and distinct actions under Clean Air Act (CAA) section 129. In the first action, the EPA proposes to consolidate the existing provisions governing air curtain incinerators (ACI) that only burn wood wastes, yard wastes, and clean lumber into one new rule subpart. Specifically, we are proposing to consolidate the opacity limitations and associated monitoring, recordkeeping, and reporting requirements that currently exist across various subparts for CAA section 129 source categories: large municipal waste combustors (LMWC), small municipal wast…
