Industrial Site Information: NRG Indian River Power Plant

 

The Indian River Power Plant is a 784-megawatt facility located near Millsboro that produces electricity, primarily from the combustion of coal. It is owned by NRG Energy, which operates a variety of energy-related operations worldwide. An overview of the Indian River Generating Station near Millsboro 

In January 2009, DNREC and Indian River Power LLC, owner and operator of the Indian River power plant, reached a settlement based on a complaint filed by DNREC to resolve opacity (visible air contaminants such as smoke and dust) and nitrogen oxides (NOx) violations at the electricity generating plant in Sussex County.

As part of the settlement, Indian River Power will investigate and evaluate the opacity violations on Units 3 and 4, implement an optimization plan for the electrostatic precipitators (particulate control devices) for Units 1, 2, 3, and 4, and establish policies to minimize opacity and nitrogen oxides violations. The settlement will also require Indian River Power to purchase and provide to the Department an Ultrafine Particle Monitor and pay a civil penalty of $5,000.

In 2007, DNREC and NRG signed a consent decree requiring the facility to dramatically cut air pollutants by 2009. DNREC issued a permit for the construction of the Phase II Industrial Landfill in October 2008. Construction of Cell 1 of the Phase II Landfill was completed in September 2010 and that cell is currently in use.

DNREC has also issued Acid Rain and Title V permits to the Indian River Power Plant permits.

In addition, DNREC's Site Investigation and Restoration Section has issued a Final Plan of Remedial Action for Operable Units 1 & 3 for the adjacent Burton Island Ash Disposal Area. (Please see Secretary's Order No. 2008-A-0032 – Approval of Final Plan of Remedial Action for Burton Island Ash Disposal Area (Operable Units 1 & 3) in Millsboro.) 

The Proposed Plan of Remedial Action and Final Feasibility Study for Operable Unit 2 have also been issued.

A public hearing on the proposed plan of remedial action for the Burton Island historical ash disposal site, Indian River Generating Station's Operable Unit 2 (DE-1399), was held on Feb. 7, 2013 in Millsboro.
