Ninemile Creek Stormwater Pollution Prevention Plan, March 2012

The remediation of Ninemile Creek is part of the continuing efforts to restore and clean up Onondaga Lake, adjacent plant properties, and tributaries. Ninemile Creek is one of the main tributaries to Onondaga Lake and is part of a complex system that provides habitat corridors to upstream wetlands and green areas. This system flows through the restored Linden Chemical and Plastics (LCP) wetlands, connects with the West Flume, flows into Geddes Brook and Ninemile Creek, and empties into Onondaga Lake.

This Stormwater Pollution Prevention Plan (SWPPP) covers on-land work to be performed at Ninemile Creek, pursuant to the Record of Decision for Operable Unit 1 of the Geddes Brook / Ninemile Creek Site. It was developed pursuant to the New York State Department of Environmental Conservation (NYSDEC) State Pollutant Discharge Elimination System General Permit for Stormwater Discharges from Construction Activities and the New York State Standards and Specifications for Erosion and Sediment Control. It includes the following objectives:

  • The reduction or elimination of erosion and/or sediment loading to Ninemile Creek due to on-land remediation activities,
  • The identification and control of potential sources of sediment from stormwater runoff that may affect water quantity and quality and
  • The identification of stormwater/erosion control features and procedures for implementing these features.

The design includes:

  • The removal of approximately 50,000 cubic yards of soil/sediment from Ninemile Creek channel and adjoining floodplains and the
  • The construction of a habitat restoration approach that includes:
    • Increased sinuosity and length of Ninemile Creek;
    • Improved channel substrate for fish spawning and benthic macroinvertebrates;
    • Riparian, wetland and upland habitats with a diversity of native species;
    • Increased water depth under low flows to provide fish and canoe passage.
