NRG reached a consent decree agreement (CDA) with the Delaware Department of Natural Resources & Environmental Control to reduce the nitrous oxide (NOx) and sulfur dioxide (SO2) emissions at Indian River Station Unit 4. The unit is part of on a multi-unit site near Dagsboro in Sussex County, Del.

The Indian River Station consists of four operating coal-fired units. As part of the CDA, Units 1 and 2 will cease operation by May 1, 2011, and May 1, 2010, respectively. Per separate agreement, Unit 3 will cease operation in 2013. Unit 4 achieved a COD in 1980 and burns low-sulfur Eastern bituminous coal in a pulverized coal boiler.

Burns & McDonnell was contracted by NRG to complete EPCM services associated with the project. The company is providing design and procurement management services under an engineering services agreement and construction management and startup of the new equipment under a construction management agreement.
