The purpose of the exempt source/conditionally insignificant activities rulemaking is to clarify permit requirements for small sources of air emissions and update rules governing the treatment of small air pollution emitting activities. These activities are described as “insignificant activities” and “conditionally insignificant activities” in the rules. The MPCA is also considering creating new categories of conditionally exempt sources, such as auto-body refinishing facilities and woodworking facilities. Such facilities that meet applicable technical standards would be exempt from obtaining an air emissions permit.
This rulemaking is needed to address several issues with the requirements for conditionally exempt stationary sources and conditionally insignificant activities (CIA), and to meet federal requirements for affected sources. Historically, the MPCA created an air emission permit hierarchy to incentivize the small source facilities, such as auto body refinishing facilities, to reduce their air emissions through more streamlined compliance requirements for low air emissions. The rule amendments will continue to streamline the administrative requirements for the lower emitting small source facilities while complying with applicable state and federal requirements. The main benefit of the rule amendments will be administrative, but they will also ensure that the rules limiting air emissions are federally enforceable.
