Massachusetts Department of Environmental Protection (MassDEP)Top Case Best Available Control Technology (BACT) Guidelines

This information is maintained by the MassDEP, Bureau of Air and Waste, Air Pollution Control Program, and is subject to change.These listings present Top Case BACT guidelines for Non-major air contaminants emitting sources.

For a particular air contaminant subject to BACT under a Prevention of Significant Deterioration (PSD) permit, or Lowest AcheivableEmission Rate (LAER) under 310 CMR 7.00 Appendix A, Emission Offsets and Nonattainment Review, collectively termed MajorNew Source Review, the Top Case Guidelines do not apply. PSD BACT and Appendix A LAER must be analyzed on a case-by-casebasis.

This Guidance is published for informational purposes only. Use of the applicable Top Case BACT emissions limitations containedherein may preclude the need for applicants to prepare and submit a “top-down BACT analysis” for MassDEP’s review, and willstreamline the Air Quality permitting process for both the applicants and MassDEP. Applicants should note that BACT requirementsfor any new or modified air contaminants source are subject to change through the MassDEP 310 CMR 7.02 Air Quality PlanApproval (permitting) procedures. Please contact the MassDEP Regional Office that regulates your facility should you have anyquestions related to these Top Case BACT guidelines.

Please be aware that, in addition to BACT requirements, federal NSPS, MACT and/or GACT requirements may also apply pursuant to40 CFR Parts 60, 61 and 63.

*Capture efficiency determined by US EPA Method 204 for Permanent Total Enclosures (PTE). PTE criteria: any natural draft opening (NDO) is at least four equivalent opening diameters from each pollutant emitting point; the total area of all NDO’s shall not exceed 5 percent of the surface area of the enclosure’s four walls, floor, and ceiling; the average face velocity (FV) of air through all NDOs shall be at least 3600 m/hr (200 fpm). The direction of air flow through


all times during routine operation of the process; all PM and HCl emissions are captured and contained for discharge through a control device.
