Air Monitoring Information

Charter Environmental and Axiom, Inc. continue to monitor the four sampling locations during the 8 -hour day for dust particulate. Asbestos monitoring was conducted through August 19, 2005. Asbestos abatement activities have been completed and monitoring of this material has concluded. Dust particulate monitoring continues.

The four perimeter sampling stations are set up in the following locations:

Station 1 -- Site fence gate on Pleasant Street
Station 2 -- Site fence on east end of Church Street
Station 3 -- Site fence on bike path at Tripp Street
Station 4 -- Site fence at bike path near Adams Street

The dust particulate and asbestos sampling results recorded at each station every hour in a monitoring log. These results are compared to the action levels established for each parameter. These action levels are concentrations at which it is deemed unsafe and work would have to stop.

Results of the air monitoring data has shown that exposure of unsafe conditions to workers in the exclusion zone and to the public is well below the actions levels.

Dust Particulate Monitoring -- The National Ambient Air Quality standard for particulates is 150 micrograms per cubic meter (µg/m3) over an average of 24 hours. This value will be used, however, for a one hour period. Heavy metal presence is factored into determination of this action level. The average levels recorded at these locations range from 0 to 0.039 (µg/m3), with most readings valued at zero. The maximum level for this week is also recorded and ranges from 0 to 9.549 (µg/m3).

Asbestos Monitoring - During abatement activities, asbestos monitoring is conducted on a continuous basis as well. Readings are taken and recorded every hour. The personal space for asbestos workers is also monitored continuously.

The action level for asbestos is 0.010fibers per cubic centimeter (f/cc). Average readings range from 0 to 0.003 f/cc, well below the action level. Most readings were non-detectable. Samples from each location are also taken into the trailer for microscopic readings to verify the data.

Actual Data - Below are tables showing the average and maximum dust particulate and asbestos readings taken at each sampling location from August 18 through August 24.
