The Connecticut Department of Energy and Environmental Protection (DEEP) published notice of intent to repeal the current Regulations of Connecticut State Agencies for control of nitrogen oxide (NOx) emissions and in lieu adopt two new regulations.

The new proposed regulations will make the NOx emission limits consistent with emission limits achievable through current reasonably available control technology (RACT) according to a May 18, 2016 Trinity Consultants report.
In particular, the proposed new regulations include the following:

• RCSA 22a-174-22e “Control of nitrogen oxides emissions from fuel-burning equipment at major stationary sources of nitrogen oxides” proposes a phased implementation of fuel specific NOx emissions limits for fuel burning equipment at major sources of NOx. The regulation also includes reemissions monitoring and testing, record keeping and reporting to enable sources to demonstrate compliance with the emissions limitations.
• RCSA 22a-174-22f “High daily NOx emitting units at non-major sources of NOx” requires the non-major sources of NOx to maintain the equipment in proper operating condition and track daily NOx emissions during the summer months. In case the daily NOx emissions exceed the levels specified then sources will be regulated by CSA section 22a-174-22e.

What this means to you
Connecticut is proposing to replace two fuel-burning equipment NOx regulations: One – a proposal of phased implementation of fuel specific NOx emissions limits for fuel burning equipment at major sources of NOx – includes re-emissions monitoring and testing, plus record keeping and reporting to demonstrate compliance. A second requires non-major NOx sources to maintain equipment in proper operating condition and track daily NOx emissions during the summer months.
