Subpart YYYY Stay lifted-extremely low-level testing required-are you impacted?

March 31, 2022

Decatur, AL, March. 31, 2022 – The U.S. Environmental Protection Agency (EPA) has finalized the amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Stationary Combustion Turbines. This final action removes the stay of the effectiveness of the standards for new lean premix and diffusion flame gas-fired turbines that were promulgated in 2004. The main challenge with this is the low-level formaldehyde testing requirements—and the limited resources available (equipment and personnel) across the entire industry to conduct this testing within an extremely limited timeframe. Standard FTIR equipment will NOT measure at the levels necessary for this rule.

What does this mean for your facility?

If you started up a new or reconstructed stationary combustion turbine located at a major source of HAP emissions, you must comply with the emissions limitations and operating limitations in this subpart no later than March 9, 2022—which means Initial performance tests or other initial compliance demonstrations must be conducted within 180 calendar days of March 9, 2022.  Two other factors may impact you—there is a 60-day EPA notification requirement, and there are limited providers (Alliance is one) that have the equipment and expertise to test at the extremely low levels (formaldehyde in two-digit Parts Per Billion (PPB)) required for compliance demonstration.
