Institutional controls are required for this site.
This site requires ICs because a decision document, such as a Record of Decision, has documented some level of contamination and/or remedy component at the site that would restrict use of the site. These ICs are required to help ensure the site is used in an appropriate way and that activities at the site do not damage the cleanup components. These ICs will remain in place for as long as the contamination and/or cleanup components stay on site.   The site contacts should be consulted if there are questions on the ICs for this site.

The former Material Technology Laboratory in Watertown, Massachusetts, closed under the Defense Base Realignment and Closure Act of 1988. Wastes generated by the facility while it was operating have contaminated soil and groundwater at several areas across the site. Most of the site property has been transferred to private ownership, with the Town of Watertown retaining a small parcel and the State of Massachusetts owning another parcel. After cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in September 2006.
