a. Old Business, Approval
of Minutes, Mr. Jim McKenna, Radford AAP Restoration
Minutes of the 21 January 1999
meeting were approved.
Introduction of Mr. Robert Freis.
Mr. Robert Freis introduced himself to the other members. Mr.
Freis worked as a reporter for the Roanoke Times (Christiansburg
Office) and as such wrote a series of articles last fall about
the plant, one series pertained primarily to environmental issues.
Mr. Freis was unanimously voted into the RAB as a member.
of the Solid Waste Management Unit 8 Status (SWMU8),
Mr. Arne Olsen, ATK:
Remedial Project: A-B line acidic
wastewater settling lagoon.
SWMU 8 Background:
- Below grade earthen lagoons
Produces calcium sulfate sludge
- De-watering the lagoon (water
to outfall 007)
- Sludge removal (adjacent drying
- Removal of 24" of soil
from bottom of lagoon
- Soil placed in adjacent drying
- Subcontracted work completed
- Soil sampling (off-plant facility),
- No constituents were detected
- Residential risk-based numbers
that EPA publishes
- Permit health-based numbers
- New concrete tank
- More efficient settling
- Eliminate ex-filtration from
tank to lagoon
- Easier sludge removal
Assuming that the tank passes the
leak test, it will go into operation sometime in April of this
of the New River Unit/Bldg. 4343 Status, Ms. Davida Trumbo,
ICF Kaiser (Enclosure 1):
Conduct a remedial investigation
feasibility study at both Northern and Western Burning Grounds
of the New River Unit and a Resource Conservation Recovery Act
P (RCRA) facility investigation at Bldg. 4343.
The investigation overview is to
insure the accuracy and integrity of the work that will be conducted.
In 1990, ICF conducted remedial
investigation preliminary accounts of the Northern burning ground
in cooperation with ATK. ICF went in with geophysical survey
delineated areas that had been impacted from previous burning
activities and collected environmental samples of both surface
and subsurface soil for analysis. Evidence of lead was found.
In terms of contaminate nature
and extent, ICF has seen metals in the soil. Part of the initial
investigation was to verify the previous investigation results
and determine the nature and extent in terms of both lateral
and vertical extent of the contamination.
ICF will be conducting both ecological
and human health risk assessments to see if there are any potential
risks to human health and environment at the Northern Burning
ICF will be conducting initial
screening activities at Bldg. 4343 to verify previous investigative
results conducted by ATK in 1996.
Currently, ICF is looking at soil
and potential surface water settlement for the Northern and
Western Burning Grounds. Screening with lead test kits will
provide real time information to optimize the sample design.
ICF will be collecting some confirmatory samples to decide whether
or not there is still a problem with metals, SVOCs, and PAHs.
ICF will also be evaluating locations that have cadmium concentrations
above RCRA regulatory limits. ICF will collect verification
samples and then ICF will do systematic sampling to determine
whether or not there is any other potential contaminates surrounding
Investigation activities include
the mobilization, surface water/sediment. Subsurface soil, IDW
management, and demobilization. Tentative schedule is sometime
d. Installation Action
Plan, Mr. James McKenna (Enclosure 2).
Department of the Army requires
this plan. This program document is required to be done annually.
It describes RFAAPs sites, past actions, clean-ups, public
involvement, RAB, cost whats been paid; whats
the program for this year whats the program for
outyear, and site descriptions.
e. Meeting with EPA, March
11, 1999, Mr. Rob Davie, Mr. James McKenna (Enclosure
Discussed regulatory documents
for RFAAP and regulatory status for New River Unit.
The committee requested that one
of the next RAB cover more detail on ground water.
The next meeting is scheduled for
May 20th @6:00 p.m. A tour of the New River Unit
in Dublin has been scheduled. R.S.V.P. to Joy Leketa NLT 17
May, (540) 639-8611.
