1. The meeting began with an introduction from Steve Ackerlund at 6:10 PM.
     a. He discussed having a citizen’s jury (see attached description)

2. Rebecca Thomas discussed two documents (see attached)
     a. Property projections
     b. Clean-up fact sheet

3. Rebecca also discussed timelines for the overall project.  A final Toxicity value is due this fall and the risk assessment is due then too.  It is anticipated that the EPA will release a planned remedy in early 2015 for public comment.

4. Deb McKean a Risk Assessment Update: conceptual site model, background, exposure data, toxicity values and decision making
    a. Two handouts (see attached) and a PowerPoint were presented (get PowerPoint!).  
    c. Analysis- PLM-VE- light microscopy soil characterization. TEM- electron microscopy. This method can detect fibers more accurately.
    d.  Research Rally- Interesting to do a spacial representation of values reported by EPA.  4 fibers per cubic meter of air with modern air samples vs. 1-10 per cubic centimeter. Maybe also put toxicity values in there. Soil values. Etc. cancer toxicity value (IUR- inhalation risk unit) is 0.17 fibers per cc.  RfC –reference concentration 20 fibers per cubic meter.  This is the lowest level of exposure that doesn’t cause disease and an uncertainty factor and a lifetime exposure.
