Technical Assistance to Brownfield (TAB)
• A national program• Funded by EPA • Free to communities• K-State assists
communities in EPA Regions 5, 6, 7 and 8

The Early Years of Mining Reclamation1980 -1990
Superfund & the NPL
• Clear authority for sites where there is an imminent threat to people
• Must score 28.5 on the HRS

Cleanup Approach
• Usually very large sites, complex cleanups
• Water treatment (often) at the end of the tunnel
• NPDES Permitting

Problems with the NPL Approach
• “Superfund” not so “super”
• Eco Threat Sites vs. People threats
• Too many widely dispersed small contributors to constitute a single site
• Abandoned sites• Sites scoring less than 28.5
• Future property transactions
• Scares potential good samaritans

Local ExampleIdarado
• Not a “true NPL site”• $20 M• Direct Revegetation• Performance Goals– Coverage– Diversity– Water quality

The Next Generation of Regulation1990 - Present
Voluntary Cleanup Programs• Great Mechanism for taking charge on a site and
deflecting NPL/EPA
• How to keep EPA out? MOA– Some CERCLA relief provided (no CERCLA Good Sam before 2007)– No CWA relief– NPL Caliber not eligible
• Risk based cleanups

Cleanup Approach
• Contour• Cap • Revegetate• Divert Adit Drainage
around piles• Risk-based cleanups

Shortcomings of VCP
Inability to address large sites
Enforcement authority??
No Good Samaritan Clause

The Next Generation of Regulation1990 – Present
Community Based Stakeholder GroupsMotivated citizens and PRP’s and agencies collaborate to prevent NPL listing of the site

Cleanup Approach
• Study and coordinate cleanup effort• Seek funding for cost-effective solutions using
existing programs/authority• Limited to actions that do not result in the
discharge of pollutants or release of haz waste• Collaboration

Limitations for Community Based Stakeholder Efforts
Voluntary Effort– Needs willing participants (both members &
responsible parties)
Funding, Funding, Funding– Implementation– O&M
Large Water sites (No Good Sam)
Long Term Staying Power?

The Current Generation of Mining Reclamation; 2005 - Present
Collaboration and Innovative Uses of Regulatory Authority
• Targeted Listings
• Non Time Critical Removals– OSC’s & CERCLA Authority
• Collaboration– Public-Private Partnerships– Interagency

Cleanup Approach;Tools Used
• Segregating dirty from clean water
• Environmental covenants

Problems
• Good Samaritans still not motivated to participate…liability fears
• Citizen suits under the Clean Water Act

Local Case ExampleCaribbeau Tails, Ute-Ulay, Nelson Tunnel
• Caribbeau: Non time critical removal planned for 2015
• Ute Ulay: Non time critical removal done in 2014
• Nelson Tunnel: ongoing targeted listing

What is Next?2015 and Beyond
• True Good Samaritan Act
• True walk-away technologies that better mimic natural processes
