Is your facility subject to the major source Boiler MACT requirements (40 CFR 63, Subpart DDDDD)? January 31st is an important deadline for facilities to submit their required compliance certification reports.

A facility is designated as a major source if the facility emits or has the potential to emit 10 tons per year or more of any single hazardous air pollutant (HAP) or 25 tons per year or more of any combination of HAPs. New, reconstructed, and existing boilers or process heaters firing most fuel types (including natural gas, coal, diesel, etc.) are considered affected sources under the major source Boiler MACT.

Facilities required to submit semi-annual or annual compliance certification reports must submit the compliance certification report via EPA CDX's CEDRI (Compliance and Emissions Data Reporting Interface) program by Thursday, January 31st. Facilities required to complete more infrequent (biennial or 5-year) compliance certifications should also submit their compliance certification report by January 31st if the facility completed the required boiler tune-ups in 2018.

If you have any questions on Boiler MACT applicability, completing energy assessments or tune-ups, or need help submitting your facility's compliance certification, contact Trinity's Kansas City office at (913) 894-4500.
