Attention: Mr. D.V. Pearson
Subject: March 31, 1989 Proposed Remediation Plan
Greensboro Junction Tank Farm, Guilford County
North Carolina, Incident No. 3893
Dear Mr. Pearson:
I have reviewed your proposed plan of action which was
received by our office on April 3, 1989. Your proposal has
been found to be generally acceptable. Implementation of
this remedial activity may proceed following these
conditions:
1) The vertical ex -Cent of soil contamination must be
determined and presented in the first quarterly
sampling report.
2) Soil samples may be analyzed utilizing EPA Method
418.1 plus the Purge & Trap Method using the GC
procedure with PID detection. This is discussed
in EPA SW-846, Method 5030. This will cover the
volatiles which are lost during sample collection
and laboratory preparation.
3) Submit the above information to this office within
30 days of the quarterly sampling period.
4) The effectiveness of this plan of action will be
determined after reviewing three quarterly
reports. If these sampling reports indicate that
this program has been successful, it may proceed
unchanged. However, if the quarterly reports
indicate that reduction in petroleum hydrocarbons
has not decreased, a more active form of
remediation will be required.
