Invista Seaford Power Plant

{{#badges: CoalSwarm| Climate change}} Seaford Power Plant is a coal-fired power station owned and operated by Invista (which was spun off from DuPont in 2003) in Seaford, Delaware. The plant provides power to Invista's Seaford synthetic textiles manufacturing facility.

Background

In 1939, materials science giant DuPont acquired 609 acres (2.46 km2) near Seaford for a nylon production plant. The $8.5 million investment (and consequently the 1,400 construction-related jobs it brought) was welcomed by locals with an impromptu parade. The Seaford plant went into production on December 12, 1939 and the first yarn produced by the plant can be viewed at the Smithsonian Institution in Washington, D.C. Bulked Continuous Filament nylon, a standard in the carpet industry, was developed at the Seaford plant in 1958. The Seaford plant employed over 4,600 employees at its peak in the late 1960s and early 1970s. By 2004, this number had dropped to about 650. Dupont later spun off the nylon fibers business (along with Lycra and other products such as Teflon) into a wholly owned subsidiary called Invista. Invista was later sold to Koch Industries, Inc. for $4.2 billion on April 30, 2004

Seaford Environmental Violations

The Seaford plant burns coal and in 2001 reported discharging into the air 130 pounds of the neurotoxin mercury. Total “Toxic Release Inventory” on-site releases for that year were 469,000 pounds. For 2005, the total was 602,000 pounds. By 2007, the amounts reported had increased to 764,000 pounds. Careless disposal of coal ash on the site has contaminated groundwater with arsenic, carbon tetrachloride, and other toxic chemicals.

A December 2008 EPA Region 3 progress report on the Invista Seaford Plant found arsenic in the underlying groundwater, and stated the "source of the arsenic is most likely coal ash generated by the site’s power plant." Invista has said it is converting its coal-fired boilers to natural gas, however activists such as Citizens for Clean Power and the Sierra Club argue any additional coal ash generated should only be disposed of in a lined landfill.

In April 2009 it was determined that INVISTA would pay a civil penalty of $850,000 to EPA and a civil penalty of $500,000 to Delaware for environmental violations found through audit at various INVISTA facilities, including the INVISTA-Seaford Plant. A Consent Decree was lodged in the U.S. District Court for the District of Delaware specifying corrective actions expected to result in net reductions in emissions from three boilers at the Seaford plant of 1,029 tons per year of nitrogen oxides; 4,211 tons per year of sulfur oxides; and 269 tons per year of particulate matter.

INVISTA must control NOx, SO2, and PM by ceasing to use coal at the Seaford boilers through installation of a natural gas-fired boiler and switching the existing boilers to burn only low-sulfur fuel oil for a maximum of four months. Under this option emissions are limited to 118 tons of NOx and 353 tons of SO2 on a 12-month rolling average basis. INVISTA is also required to limit sulfur content in all vaporizer fuel to 1%.

From Setember 2002 until January 2008, the Delaware Department of Natural Resources and Environmental Control (DNREC) collected ambient water quality measurements of the Nanticoke River which recieves the discharge from the Invista coal ash surface impoundments and ash landfill leachate. These measurements detect arsenic in the recieving water above the ambient water quality criteria of 10 ug/L arsenic in one sample set.
