Cleco Power LLC said in a Dec. 4 filing with the Louisiana Public Service Commission that an August 2012 federal appeals court decision that threw out the U.S. Environmental Protection Agency’s Cross-State Air Pollution Rule (CSAPR) doesn’t change its need for selective non-catalytic reduction (SNCR) equipment at two plants.
The plants and units getting the SNCRs are Rodemacher Unit 2, which is located at the Brame Energy Center, and also Dolet Hills. Cleco Power noted that while it had initially planned to only run SNCR for NOx control during the summer ozone season on Rodemacher 2 and Dolet Hills, the Louisiana Department of Environmental Quality has indicated that state statute requires that they be run year-round. Cleco said the SNCR at Dolet Hills is complete and going through fine tuning, while the SNCR at Rodemacher 2 is 70% built and due for completion in the second quarter of 2013.
Most of the Dec. 4 filing is taken up with an attached copy of the August ruling from the U.S. Court of Appeals for the D.C. Circuit that threw out CSAPR and required EPA to either amend or replace it.
Cleco owns 50% (325 MW) of the lignite-fired, 650-MW Dolet Hills plant. It owns 30% (157 MW) of the 523-MW, Powder-River-Basin-coal-fired Rodemacher Unit 2.
In its November 2011 application at the PSC regarding these projects, Cleco Power said that the SNCR for Rodemacher 2 would cost it about $4.5m and another $6.5m for Dolet Hills.
