Lyons Falls Paper Mill

Lewis County, New York 

The Lyons Falls Paper Mill is a former industrial mill site located along the Moose River in Lewis County, New York. The mill was in operation under several owners from 1894 until 2001 when it was decommissioned. Through bridge funding provided by The Development Corporation of the North Country, the Lewis County Development Corporation has purchased and is currently working to redevelop the site as an industrial business park.

 Sienna, under subcontract to Conestoga-Rovers & Associates, provided environmental investigation of the ancillary structures on the site. The site encompasses a 9.4 acre parcel with various historical mill structures remaining, including; wood processing buildings, a pulp and paper mill, warehouse space, associated office areas, maintenance shops, and a boiler/steam plant. A few of the sites' buildings are still in use as storage and warehouse space, while the majority of the site exists in varying states of disrepair.

Sienna's scope of work included:

  • PCB in paint inspection, and sampling
  • Budget estimate
  • Project monitoring and air sampling
  • Laboratory Analysis of air samples by phase contract microscopy (PCM)

Sienna's investigation was conducted as part of the inventory of ancillary structures and provided an environmental assessment and budget estimate for the remediation of hazardous materials necessary to complete the planned demolition scope of work. Currently, the ancillary structures include small buildings or sheds, concrete foundations and slabs, aboveground tanks and process equipment, above group piping and conduit, steel frames and pipe supports, stacks and ductwork, concrete dikes, retaining walls and stacks scattered throughout the property. Demolition of the ancillary structures will be essential to opening up much of the mill yard for redevelopment.
