Colorado Enclosed Combustor (ECD) Testing

On October 31, 2022, the Colorado Department of Public Health and Environment (CDPHE) Air Pollution Control Division (APCD) issued Version 1 of their enclosed combustion device (ECD) performance test protocol. The public comments and CDPHE-APCD responses have also been published.

This protocol outlines general procedures for measuring the control efficiency of ECDs. Erthwrks public comments aimed to remove unnecessary testing requirements and broaden acceptable methods to meet the necessary requirements of Regulation Number 7, Part D, Section II.B.2.h (only).  Erthwrks has decades of ECD testing experience and their subject matter experts are available to assist operators to comply with these new requirements, as well as any additional facility permit requirements.
