A public hearing will be held in the Millsboro Fire Hall at 6 p.m. Thursday for DNREC’s proposed cleanup plan for a former coal ash disposal site on Burton Island at the confluence of Indian River and Island Creek.
The 144-acre site is a part of the Indian River Generating Station property currently owned by NRG Energy affiliate Indian River Power LLC.
The property was previously owned by Delmarva Power & Light Co., which used the land as a coal ash landfill from 1957 to 1979.
That ash disposal caused soil, groundwater, pond water and pond sediment to become contaminated with metals, including arsenic, barium, mercury, selenium and thallium, according to DNREC, which says the contamination poses risk to aquatic and terrestrial wildlife.
DNREC is proposing to use grading and vegetation to stabilize slopes and control erosion inside of the former landfill’s footprint. The project also would include perimeter controls to limit trespassing, a long-term stewardship plan and limits on future land use.
A copy of DNREC’s proposed plan can be found at the Millsboro Public Library and at www.dnrec.delaware.gov/whs/awm/SIRB/Pages/SIRBPlans.aspx.
