Brownfields
• Urban definition – a real property, the expansion, redevelopment, or reuse of which may be complicated by the presence of a pollutant
• Includes real or perceived
• Mine-scarred lands
3
• MSL added to Small Business Liability Relief and Brownfields Revitalization Act of 2002
• MSL includes lands, associated waters, and surrounding watershed where extraction, beneficiation or processing of ores and minerals (including coal) has occurred
• MSL considered Brownfields even if chemical contaminants are not primary barriers to revitalization
4
Brownfields Meet Mine-Scarred Lands (MSL)
• Aquatic ecosystems degraded by Acid Mine Drainage (AMD) and increased erosion
• Visual and chemical impacts of spoil piles and washing operations
• Sedimentation of waterways
• Limited infrastructure and level land to redevelop
• Limited land access
5
Characteristics of MSL Watersheds
• 36 square miles
• Communities built on coal, now in decline
• Abandoned mine lands
• Potential adverse impact to local environment/ water quality
• Coal Creek 303d listed as partially impaired
Coal Creek Watershed
6
• How can these environmental impacts be quantified over such a large area?
• How can Brownfields be applied to non-point sources, and still be a catalyst for economic recovery?
• How do you stimulate interest by large landholders to develop properties for redevelopment?

Initial Assessment – Historical Data
• Mines– Strip
– Deep
• Water quality– Chemical
– Physical
• Biological– Fish
– Benthicinvertebrates
• Data distribution

Environmental Data
Map deleted. Contact project coordinators to view.
• Strip benches and deep mine portals throughout watershed (numerous non-point sources)
• Some flooding corrected (removed from 303d listing due to siltation)
• Water chemistry (pH, TSS, alkalinity) indicates generally acceptable water quality (24 samples collected seasonally)
• Coal Creek listed as partially impaired based on pathogens (must reduce by 56%)
• Terrestrial and aquatic habitats degraded throughout watershed
14
Environmental Conditions
Geodatabase Construction
• Populated with all existing data/ information
• Interlinked with base layers– USGS topographic maps
– Roads, political boundaries
– Hydrology, land cover
• Integrated geodatabase for modeling, analysis– Guide for this assessment
– Tool for future redevelopment efforts
15
• Recent aerial photography
• Photointerpretation
• Land use/land cover classification
• sub-watershed delineations
• Sediment contributions via Revised Universal Soil Loss Equation (RUSLE)
• Identification of data gaps
• Geodatabase integration
• Target properties selection16

Sub-Watershed Sediment Loading Prioritization
21
Base Flow Data Results
• Water quality similar to historic sites
• Slightly abnormal conditions in two sub-watersheds where past mining took place
• Perception more of a “contaminant” than constituents
• Aquatic habitat quality lower than other streams in the region
• Healthier aquatic communities in headwaters and tributaries of Coal Creek than in Coal Creek
• Seeds for improvement22
Target Property Selection:Priority Site Screening Criteria
A property may be chosen if it…
• is a source of Acid Mine Drainage
• has visual or chemical impact
• contributes to erosion or siltation
• has historically/culturally important features
• has potential to build tourism infrastructure
• has ecological important features

25
Phase I and Phase II Environmental Assessments
• Pursuit of current economic development strategy
• Focused volunteer clean-up efforts
• Stream bank stabilization grants from TDEC and OSM
