Update on the Niagara River U.S. RAP Niagara River Remedial Action Plan Implementers Session April 10, 2013 NYS Department of Environmental Conservation U.S. Niagara River RAP Overview • Planning process/addressing sediment • Hydrilla • Project Updates NYS Department of Environmental Conservation U.S. Niagara River RAP Planning in the U.S. AOC Program • Individual AOCs: EPA asked managers to produce detailed action plans by early 2012 – To support measurement of progress – As a basis for distributing future funding • Program-wide: Restoring AOCs remains in the top three priorities in allocating GLRI funding NYS Department of Environmental Conservation U.S. Niagara River RAP EPA Priority Setting • Targeting AOCs that may have an opportunity to delist sooner than others • Sediment contamination is a significant factor in selecting AOCs to target – Is the extent of contamination known? – Is a plan in place for remediation where required? NYS Department of Environmental Conservation U.S. Niagara River RAP Status of Niagara River Sediment • Sediment projects completed at 16 locations, over 300,000 cubic yards removed • Many projects have addressed potential contamination sources (point sources, hazardous waste sites, etc.) • Extent of contamination remaining in sediment is not well defined NYS Department of Environmental Conservation U.S. Niagara River RAP Federal Assistance for Sediment • Late 2011 – NYSDEC requests a federal sediment assessment in the River and lower reaches of tributaries • Summer 2012 – EPA informs NYSDEC that they have allocated some funding and will begin project • Shortly afterwards, EPA informs NYSDEC of need for boundary change NYS Department of Environmental Conservation U.S. Niagara River RAP Boundaries of the U.S. AOC • 1994 Stage 2 RAP – no defined geographical boundary lines for the AOC – describes the tributaries and clearly identifies them as source areas • Beginning around 2004, EPA mapped all AOC boundaries NYS Department of Environmental Conservation Niagara River Area of Concern (U.S. Section) 2005 EPA Mapping NYS Department of Environmental Conservation U.S. Niagara River RAP Source Area Tributaries • Gill Creek • Cayuga Creek • Bergholtz Creek • Little Niagara River • Tonawanda Creek • Ellicott Creek • Two Mile Creek • Rattlesnake Creek • Scajaquada Creek • Lackawanna Ship Canal • Smokes Creek NYS Department of Environmental Conservation U.S. Niagara River RAP EPA Guidance for Modifying Boundaries • “the geographic locations within the AOCs where there are beneficial use impairments have been referred to as ‘Impacted Areas,’ and the geographic location or areas within the AOCs that cause or contribute to beneficial use impairments have been referred to as the ‘Source Area.’” • “BUI assessments need not be performed in Source Areas.” NYS Department of Environmental Conservation U.S. Niagara River RAP Modifying Boundaries • The tributary areas will be designated source areas • The existing AOC (2005 boundaries) designated the Impact Area of Concern NYS Department of Environmental Conservation U.S. Niagara River RAP Hydrilla • Native to Australia, Asia, Africa • Forms dense surface mats that can block sunlight and displace native plants • • • • Roots in sediment; can grow stems 25-30 feet long Obstructs boating, swimming and fishing Blocks water intakes Any fragment can become a new plant NYS Department of Environmental Conservation U.S. Niagara River RAP Hydrilla • August 2011 – First discovery in New York, Cayuga Lake Inlet in Ithaca • September 2012 – First confirmed discovery in Western New York, Erie Canal in North Tonawanda NYS Department of Environmental Conservation U.S. Niagara River RAP Hydrilla Response • Joint survey last Fall by U.S. Fish and Wildlife Service, NYSDEC and Ontario Ministry of Natural Resources – Documented 13.5 miles of infested waters in the Erie Canal, from North Tonawanda to Lockport – Found no plants in the Niagara River proper NYS Department of Environmental Conservation U.S. Niagara River RAP Hydrilla Response Locations of Infestation NYS Department of Environmental Conservation U.S. Niagara River RAP Hydrilla Response 2013 • Further investigate extent of infestation • Evaluate treatment options • Outreach and education has been initiated and will continue through boating season – Recreational boating is the highest risk vector for spreading to other waters NYS Department of Environmental Conservation U.S. Niagara River RAP Motor Island Habitat Improvement Project Restored natural shoreline features while providing protection against wave energy and ice damage - Construction is complete - Planting to be completed this Spring NYS Department of Environmental Conservation U.S. Niagara River RAP Motor Island Habitat Improvement Project NYS Department of Environmental Conservation U.S. Niagara River RAP Shoreline Softening Demonstration Needed NYS Department of Environmental Conservation U.S. Niagara River RAP Reassessment of Sources of Contamination • Assess current loadings from waste sites, point sources, and primary tributaries • Update previous studies • Goals: Confirm that point sources are no longer significant Determine whether waste sites are still a contaminant source Estimate contaminant loadings from primary tributaries Support possible further source trackdown and abatement NYS Department of Environmental Conservation U.S. Niagara River RAP Reassessment of Sources of Contamination NYS Department of Environmental Conservation Contact Information Mark Filipski Niagara River AOC Coordinator NYSDEC 270 Michigan Avenue Buffalo, New York 14203 716-851-7130 mdfilips@gw.dec.state.ny.us NYS Department of Environmental Conservation
