This page collects and publishs ideas to help facilities impacted by the Cross State Air Pollution Rule.
Many companies must quickly do something to address the new Cross State Air Pollution Rule. For some this looks like a daunting task. Here is what these companies have said publicly:
Other that have installed equipment that reduces the SOX and NOX and can benefit from more credit sales by optimizing there operations.
We have created this page to offer our suggestions on what can be done quickly and to gather ideas from others and share them.

Where does CleanAir fit in?
Our combination of service offerings between emission testing and boiler efficiency work should translate into opportunities to maximize value for effected utilities. More efficient fuel usage will be a factor in meeting the new limits.
With increased emphasis on NOx reduction over the full calendar year there should be an uptick in SCR installations and thus an increase in tuning opportunities.
As plants add scrubbers to meet the SO2 reduction limits of CSAPR they will also be looking at ACI to reduce mercury in these same scrubbers. We should see an uptick in Hg testing and potentially an increased demand for Hg monitors as well.

NOX - Add SNRC if there is no SCR installed
This can be done by a number of companies including:
(see others listed on WPCA)
Add SNRC to the installed SCR and take one SCR catalyst bed out of service
Tune the SCR - This service is offered by CleanAir- Th
SO2 - Switch to a coal with a lower sulfur content
Blend present contracted coal and a lower sulfur content coal
improve heat rate ( combustion efficiency )
Use automated 3D probes for EPA methods 2f & 2h to get more accurate flow.
NOTE, most stack gas flow measurements and CEM flow meter calibrations are biased high due to the inherent Method 2 errors. This can result in the emissions being reported high by 10% or more.
Make sure you CEM flow meter is linear over the normal operating range.
If the present flow CEM system go out of calibration quickly and require constant maintenance switch to a low maintenance technology such a automated pitot tube.
Ozone - Tune the SCR
