The Massachusetts legislature has mandated that the MassDEP establish regulations, guidelines and standards or for determining the suitability of soil used as fill material.  The policy institutionalizes a site-specific review and approval process to expand opportunities for the re-use of excess soil excavated from development sites.  By providing a mechanism for safely managing soil, the policies increase in-state options for the re-use of soil excavated from new development projects.  Such soil often must be shipped out-of-state at substantial cost.  More importantly, in order for a property owner to be legally indemnified, reclamation soil must be shipped to a MassDEP approved facility that maintains a fully compliant ACO certification.  LEM's Rutland facility was the first in the state to secure the ACO status under the MassDEP Soil Re-use and Similar Soils policies.  Certified locations can be found on the www.mass.gov website at this link:  "Reclamation Soils" Policy and Facilities.
First on the MassDEP's listing is Jordan Overlook Farm, our Rutland location.  The Rutland facility has serviced an ever growing number of high profile clients, since its inception in 2013, such as the Massachusetts Institute of Technology, Massachusetts Water Resource Authority, Massachusetts Department of Transportation and the University of Massachusetts (Amherst, Lowell, and Boston), along with hundreds of other private and municipal organizations.  Besides its use for LEM's clients, environmental experts and construction companies throughout New England utilize our facilities.  This is due to their adherence to the highest operating standards in addition to MassDEP oversight.  This group includes nearly all of the regions most prestigious and recognizable engineering firms such as Haley & Aldrich, McPhail Associates, Weston & Sampson and construction companies such as A.A. Will Corp., J.F. White Contracting and W.L. French Excavating.  All are well respected firms and industry leaders in their own right.
