Beneficial Use Impairments

An interim success of remediation and restoration work is removing beneficial use impairments. Beneficial use impairments are designations given by the International Joint Commission representing different types of significant environmental degradation. As cleanup work is completed, and monitoring demonstrates sufficient environmental health improvements, BUIs can be removed. The list below shows which BUIs have been removed, and which remain. Once all BUIs are removed, the process of delisting the AOC can begin.

  • Restrictions on fish and wildlife consumption
  • Degradation of benthos
  • Restriction on dredging activities
  • Degradation of fish and wildlife populations
  • Bird or other deformities or reproduction problems

The Eighteenmile Creek Remedial Advisory Committee (RAC)

A group of local officials, landowners, and stakeholders selected by the commissioner of the NYSDEC to provide a balanced representation of various segments of the community along the creek. The RAC worked with the NYSDEC to organize, develop and review the Remedail Action Plan and create public awareness and support for Eighteenmile Creek.
