RE: Costilla Landfill Pit (Permit M-80-233) Approval of
consultant's proposal to attempt to sample monitoring wells MW2 and
MW3 in February and March 1997 before submitting remedial plan
Dear Mr. Espinosa:
Assuming that Mr. Marc Sydnor of Greystone is acting as Costilla
County's agent in the matter of proposing a remedial plan to deal
with the failure of monitoring wells MW2 and MW3 to yield ground
water samples during the last two sampling trips to the Landfill
Pit site, the Division agrees to allow the County to attempt to
secure samples from the wells during February and March before a
more detailed plan is required, ie. extend the corrective action
date.
Failure to secure adequate ground water samples from MW2 and MW3
during the 1st quarter of 1997, however, will confirm the existence
of a Compliance Problem and will necessitate the submittal of a
more comprehensive and detailed plan to assure the availability of
ground water samples from the wells in the future. Such plan may
involve drilling MW2 and/or MW3 deeper or even replacing them.
Submittal of the plan will be required by a Corrective Action Date
of April 1, 1997 (revised from March 1, 1997) and the plan must be
able to be implemented such that ground water samples will be
available from the two wells or their replacements at some point
during the 2nd calender quarter of 1997, ie. by July 1, 1997.
If you have any questions on the above or wish to indicate that
Greystone is not speaking for Costilla County in this matter,
please contact me.
Sincerely,
