Operating Industries, Inc. (OII) Landfill Site

PNL's Role

The North Parcel (NP) design(s) (for both environmental-only & integrated remedies) were completed in 2007. PNL made a significant contribution to both designs, especially adding value by bringing the designs to life with our 3D visual tools.

PNL continues to work with New Cure, Inc. (NCI) to manage operations and development at OII. Preparations are being made to build a retail development, "The Cascades," on the northern parcel of the site. Operations and maintenance at the site have recently included repair of erosion damage from last winter's record rainfall and repair of roadways and slopes damaged by refuse settling. Ian Webster, PNL President, is presently retained as Interim President for NCI to help manage the many initiatives brought about by the development and the complicated relations with EPA and the site's many Responsible Parties.
