RE: 
Tutu Service Station Investigation Work Plan
Dear Ms. Kwan:
This letter is intended to follow up on our meeting on May 2nd at the USEPA
Region II office attended by yourself, Sarah Odland (CDM-Federal Programs Corporation),
Ana Gloria Ramos (Esso/TEIC Coordinator), Jose Agrelot (Soil Tech), and Thomas
Danahy and Dan Nachman of Geraghty & Miller, Inc. We believe our meeting was very
productive, resulting in several technical agreements for the above-referenced work plan.
Geraghty & Miller is currently revising the work plan in accordance with our discussions.
The USEPA will be responding to our request to use Schedule 40 PVC rather than stainless
steel for monitoring well casing and screen. The revised work plan will be submitted to the
USEPA no later than May 30, 1991.
The 2nd quarter sampling report (February 1991 sampling event) for the Tutu Water
Supply Wells will be submitted to the USEPA no later than May 13, 1991. We will be
recommending the deletion of nine water supply wells from the sampling list due to non-
detectable results for parameters of concern. We request that the USEPA respond to the
2nd quarter sampling report recommendations by May 24, 1991 in order to allow for
logistical planning of the 3rd quarterly sampling event scheduled for the week of June 4,
1991.
