Expanded Public Participation - Waterford Restructure - February 22, 2021
EPA ID# NYD002080034, Permit ID: 5-4154-00002/00357

MPM Silicones LLC / Momentive Performance Materials, Inc.

Momentive Performance Materials Inc. announced in August 2020 a two-year plan to phase out basics chemicals production at its site located at 260 Hudson River Road in Waterford, New York. The company invites the public to a meeting to discuss the regulatory elements of these changes on the site's Part 373 Hazardous Waste Permit.

The public meeting is scheduled for 6:00 p.m., Monday, February 22, 2021, via a virtual platform provided below. Momentive encourages the public to participate in this meeting to learn about the elements of the changes and their environmental benefits, ask questions, and provide the site any feedback. More information is available at:

As previously announced, the two-year phase out of basics chemical operations at Momentive's Waterford site will significantly reduce the manufacturing footprint of the facility and position Waterford as a sustainable, global center specializing in advanced silicone technologies. The New York State Department of Environmental Conservation (NYS DEC) will oversee the forthcoming changes and Momentive will work with the NYS DEC to ensure compliance with applicable rules and regulations. The transition involves several elements including:

  • Closure and removal of two permitted hazardous waste incinerators;
  • Closure and removal of 15 permitted hazardous waste storage systems;
  • Closure and removal of permitted container storage areas and transfer areas;
  • Elimination of certain production waste materials; and
  • Conversion or installation of tanks and containment areas for short-term (less than 90-days) waste storage before transportation to off-site treatment and disposal.

Upon completion, this work is expected to result in:

  • 75 percent reduction of hazardous waste generated;
  • 50 percent reduction in wastewater generated;
  • 70 percent reduction of natural gas consumption;
  • 50 percent reduction in electrical power consumption;
  • 30 percent reduction in water usage from City of Waterford sources, and 50 percent reduction of water usage from river sources; and
  • 30 percent reduction in hazardous substances stored on-site.
