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?

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

• Phase II Environmental Assessment– Focus on soil and groundwater sampling

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

• Additional assessment/clean-up funding opportunities via Brownfields Program
