Leech Lake Brownfields Program • Diane Thompson Hazardous Waste Manager • Mario Reyes Hazardous Waste Technician
What is a Brownfield? • Brownfields are real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant.
Funding for Tribes in United States • In 2002, Congress passed the Small Business Liability Relief and Brownfields Revitalization Act • the Brownfields Revitalization Act authorizes $50 million in annual grants between 2002 and 2006 to Tribes and States to develop BRPs • Environmental Protection Agency (“EPA”) awards grants to Tribes and States
Leech Lake Brownfields Response Program (B.R.P.) • Initiated in 2003, the BRP is an ongoing multi-year effort by the Band’s Division of Resource Management (“DRM”) to develop a dynamic response program. • Expand the Department’s environmental enforcement capabilities. • Assert the Band’s sovereignty and civil regulatory authority. • Protect the health of the Reservation Population and the quality of the Reservation Environment.
B.R.P. Requirements under CERCLA Section 128(a) • Timely survey and inventory of brownfields sites on Tribal lands • Oversight and enforcement authorities • Effective means to approve, verify, and certify cleanup actions • Meaningful opportunities for public participation • Maintenance of public records.
Steps in Conducting a Brownfields Response Program • Site discovery • Initial investigation • Site hazard assessment • Site hazard ranking • Remedial investigation/feasibility study • Selection of a cleanup action • Site cleanup
Past and Current Sites • Facility Center –Cass Lake Underground Storage Tanks • Enbridge Pumping Station – Cass Lake • Inger Store • Division of Resource Management (DRM) • Waboose Bay Methamphetamine Lab Site
Facility Center U.S.T.’s • Two 10,000 gallon fuel oil tanks on northwest corner of Facility Center • These were removed in 2006 • Picture of tanks outside of Facility Center on next slide
South Cass Lake Station Release • Identified in May 2001 during voluntary monitoring well construction program • Source was from an underground weeping flange. Dug up and fixed, accessible impacted soil removed. • Investigation completed in phases in May 2001, September 2001, August 2002 and October 2003 • Ongoing ground water monitoring 4 times/year
U.S.G.S. Survey September 2007 • DRM, Ennbridge and United States Geological Survey (USGS) are in collaboration in dealing with the South Cass Lake Pumping Station Spill • USGS finished push-probes work on Sept. 21, 2007 • Found the dissolved plume of benzene to be 100 meters (328 ft.) further to the east-southeast than the original survey • Map of past and current plume on next page
U.S.G.S. Future Surveys • Data from September survey will be reviewed to see if any more push-probe data are needed • Decisions will also be made on where to put observation wells • A few links to look at regarding this site: http://www.lldrmenvironmental.com/Brownfields/Page06-Cleanup.htm http://enbridgecasslake.com/go/site/986/
Inger Store • The site was used as a Grocery Store/Gas Station. • Leech Lake Band of Ojibwe is the legal owner of this property. • Phase I Environmental survey completed on 7-22-91 • 3 tanks were removed from this site – all of which were in poor condition. • Two suction pumps remain at the site. • Suspected source of the release to the unsaturated soil and groundwater system was attributed to tank overfill. *** This site is ready for use as of 2006***
Leech Lake DRM Site • Planning to have botanical seed garden put on DRM site • Past owners were Wheeler Lumber/Supply Company • Minnesota Chippewa Tribe construction company • Now owned by Leech Lake Band of Ojibwe
DRM Phase I and Phase II work • Phase I – consisted of interviews of past owners and people familiar with the site • It also included searching of databases, and old documents regarding the site. • Possibly some contamination from the RCRA vault to the east and St. Regis superfund site just to the north of the DRM property
DRM – Phase II • Phase II soil sampling completed on DRM site on June 20th, 2007 • Data still being processed • Next step if needed will be the cleanup phase for the site • Photo of soil sample locations on the site on next page
Waboose Bay Site • A clandestine drug laboratory was seized on June 13, 2003 • The production of methamphetamine potentially provides immediate and long term health and safety concerns • This allotment has been and is currently occupied illegally (trespassing) by unknown individuals. • Phase I completed and report sent to EPA in November 2006 • It was approved by EPA for Phase II testing
Phase II • Soil Sampling of property completed on October 30th, 2007 • Samples were sent to STL Labs and we are waiting for the results • Photos included on next few pages of location of Waboose bay and aerial of property
