15 County Road, Approval
of Short Term Measure,
M.G.L. c. 21E, 310 CMR 40.000
The Department of Environmental Protection, Bureau of Waste Site Cleanup
(the "Department"), has reviewed a design for a Short Term Measure (the "STM
Design") submitted on your behalf (as used in this letter "you" and "yours"
refer to Hatheway & Patterson Co., Inc.) by Keystone Environmental Resources,
Inc. on January 1, 1991, titled,
m
DESIGN REPORT
FOR
SHORT-TERM MEASURE.
S
The STM Design includes a schedule and a plan to install, operate and
monitor an active product recovery system along the east bank of the Rumford
River.
The Department approves the STM Design, with the following provisions:
1. The STM will comply with 310 CMR 40.542.
2. You shall meet the requirements relative to Short Term Measures
listed on pages one (1) to three (3) of the Department's letter of
September 6, 1990. -
3. You will comply with provision k. on page three (3) of the
Department's letter of September 6, 1990, relative to monitoring
wells that have been destroyed, damaged or improperly completed.
This provision requires you to replace monitoring well MW-8A which
was reported broken in your STM Design and any other wells that
have been destroyed or damaged. The Department requires you

undertake this task and submit completion logs no later than
March 29, 1991.
4. The hydrogeology compiled to date in the vicinity of the recovery
system is incomplete and in some respects inconsistent, suggesting
surveying or gauging inaccuracies. Surveying vertical closure must
be within 1/100th of a foot, and gauging must achieve the same
level of accuracy. Piezometric contours must honor the gauging
data. In reporting piezometric head and surface water elevations,
well head elevations, depth to water and water elevations must be
tabulated.
Prior to undertaking the Short Term Measure, you will survey and
gauge monitoring wells P-3, P-4, P-5, MW-2, MW-3, MW-5A, MW-6, MW-
7A, NW-10 and MW-12, and the upstream and downstream Rumford River
gauging stations, all to the same sea -level datum. The results
shall be tabulated and an areal flow net shall be compiled that
encompasses the area occupied by these wells and by the active
recovery system. The anticipated zone of influence of the product
recovery system shall be outlined on the flow net. You will submit
these results to the Department no later than March 29, 1991.
5. on completion of the installation of the product recovery system,
you shall survey the head of the two observation sumps and of the
product recovery sump to sea -level. You will test the product
recovery system and gauge the system sumps and surrounding
monitoring wells over a range of discharge rates to determine the
rate sufficient to capture all the product while minimizing
recharge from the Rumford River. You will document this
determination with a flow net of the recharge area of the activated
recovery system.
6. You will submit a report on the Short Term Measure as -built within
sixty (60) days of the activation of the product recovery system.
7. Installation of the product recovery system will begin no later
than April 15, 1991, and the recovery system will be activated no
later than May 31, 1991.
The Department requires a written response within fourteen (14) days of
receipt of this letter indicating whether you intend to take the actions
outlined above.
You should be aware that the implementation of a Short Term Measure does
not relieve you from undertaking a full Phase II_ - Comprehensive Site
Assessment. In addition, you may have to prepare a Phase III - Development
of Remedial Response Alternatives and a Final Remedial Response Plan and you
may have to undertake a Phase IV - Implementation of the Approved Remedial
Response Alternative, if required under 310 CMR 40.000.
Please be advised that you must comply with all applicable Federal,
State and local permits throughout the implementation of the STM.

You have been previously notified of your liability in the Notice of
Responsibility letter dated August 16, 1988.
Your cooperation in this matter is appreciated. Should you have any
further questions regarding site WSC/SA-4-0571, please contact Marcel V.
Boelitz of this office at (508) 947-2868.
Very truly yours,
