Kathy,
Monitoring well MW-35 was approved by the Executive Secretary in the February 15, 2011 Permit Modification. The
As-Built report for wells MW-36 and MW-37 is due on or before June 30, 2011. Until the As-Built is approved.
Section 6.2.4 of the DUSA QAP gives DUSA some latitude on the sampling equipment they choose to use for
sampling (bailer, non-dedicated bailer, dedicated pump, or non-dedicated pump).
After the As-Built report is approved. Part I.E.ll is in effect for those wells. The intent of Part I.E.ll of the Permit,
is for DUSA to notify the Executive Secretary when they wish to change an analytical procedure or a,nalytical
method for analysis from the method specified in Table 1 of the DUSA QAP. DUSA is also not allowed to change
the equipment or design of the monitoring wells without approval from the Executive Secretary.
Therefore, DUSA is free to use any of the sampling equipment specified in Section 6.2.4 ofthe DUSA QAP, as long
as they are made of inert materials.
If you have any questions please let me know.
Sincerely.
Phil
