Public Meeting Presentation The Coal Creek Watershed Brownfields Project Anderson County, Tennessee Lake City, Tennessee November 30, 2006 Prepared by: Jason Bulluck and Berny Ilgner Presented by: Berny Ilgner

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
4
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)
5
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
6
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
7
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? 7 Challenges

Local Activism Coal Creek Watershed Foundation (CCWF) Stream bank stabilization projects Dead wood removal events River clean-ups Annual Coal Creek Health Day Annual CCWF Scholarship Fund Annual Coal Creek Miners Festival 10
11
Initial watershed assessment Geodatabase construction Integrated Pollutant Source Inventory (IPSI)-Sediment Loading Model (SLM) Data gaps/data collection Geodatabase update Site identification Phase I/Phase II Environmental Assessments Actively engage community members in the process CCW Assessment Approach/Objectives 11
12
Cultural Historical Water quality Hydrological Geological Ecological Socio-economic Landownership 12 Initial Assessment – Historical Data
13
Mines –Strip –Deep Water quality –Chemical –Physical Biological –Fish –Benthic invertebrates Data distribution 13 Environmental Data Map deleted. Contact project coordinators to view.
14
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
15
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
16
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 selection 16 Sediment Loading Model

Example of the Sediment Contribution Model Output Data 20 Model Outputs Map deleted. Contact project coordinators to view.
21
Sub-Watershed Sediment Loading Prioritization 21
22
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 improvement 22
23
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 23
24
24 Target Property – Old Block Factory Site Map deleted. Contact project coordinators to view.
25
Phase I Environmental Assessment Phase II Environmental Assessment –Focus on soil and groundwater sampling 25 Phase I and Phase II Environmental Assessments
26
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 26 Coal Creek Watershed Outlook
