Web Documents for North Ridge Estates Superfund Site

Summary Information

(last updated on: 3/31/2021 6:04:35 PM)

[March 2021] The North Ridge Estates site was developed for residential use, with approximately 25 homes on minimum lot sizes of 2.5 acres on the former Marine Recuperation Barracks. The Marine Recuperation Barracks was built in 1944 by the United States Department of Defense and consisted of approximately 82 buildings. The United States Navy closed the barracks and declared the Marine Recuperation Barracks as surplus in 1946. The Marine Recuperation Barracks buildings were sided with cement asbestos board and contained asbestos insulation, roofing material, floor tiles, and other asbestos-containing material (ACM). Heat was provided to the buildings through a series of boilers, tanks, and buried steam pipes covered with asbestos-containing insulation. ACM was present at the NRE Site as both dispersed material scattered widely across the 125-acre OU1 and concentrated material in burial areas. The total amount of buried material in these locations across NRE Site, OU1 was estimated to be approximately 76,064 cubic yards. EPA has completed multiple time-critical actions at the facilitysince 2003. The State of Oregon used its one-time nomination to place NRE on the Superfund list in September 2010. EPA initiated the Superfund listing proposal for NRE in March 2011 and the site was listed on the NPL in Sept. 2011. EPA presented the NRE Site to the National Priorities Panel, in March 2013, including a request for appropriation of CERCLA remedial action funding. Funding was assigned to the NRE OU1 site by EPA in Spring 2014. The Remedial Design was updated in December 2015. On-site Remedial Action began in July 2016 and was completed by the end of 2018. EPA issued No Further Remedial Action Planned determinations for each property within NRE OU1 in December 2020. DEQ issued Conditional No Further Action determinations for each property in January 2021. DEQ performed an annual inspection the week of August 31, 2020 in accordance with the O&M Plan. Individual ECSI Nos. were assigned to individual properties or groups of properties in order to track property specific documents (such as prospective purchaser agreements, deed restrictions, or unique findings) and future actions performed on each property by the current or future owner/occupants following completion of the Remedial Action. Documents that apply to the entire NRE site can be found here. Documents that are limited to and specific to conditions at a specific property will be found under that property's individual ECSI No.
