Enclosed are new pages for the 1992, 1993 and 1994 AHR's which <br />indicate that a visual inspection for oil and grease was performed <br />on the alluvial well samples and none was noted. <br />2. No response required. <br />3. The upper french drain was installed April 12, 1993. The Division's <br />letter notes the french drain was installed four months prior to the <br />approval of the repair plan. This is true, however by its approval <br />of MR-012, the Division approved an interim repair plan which <br />provided for the installation of the upper french drain. Enclosed <br />is a revised page for the 1993 AHR which clarifies the date the <br />upper french drain was installed. <br />4. Bear will send a copy of the information which it submits to the <br />Department of Health regarding the correction of the 1993 second <br />quarter DMR. <br />5. A revised page is enclosed for the 1992 AHR which explains the <br />meaning of "NT" (not taken) and why depth to water was not taken for <br />AA1 during the fourth quarter monitoring event. <br />6.
