Eric,
I have responded to your previously emailed comments as well as discussion items per our phone conversation
yesterday as follows:
1.The proposed Anadarko pipelines located on the west side of Cell 2 are not shown on Exhibit F, Sheet 6. I'm sure
the locations aren't finalized yet, but we need to have something showing a minimum setback of 47 feet between
Cell 2 and those pipelines unless another agreement is reached with Anadarko.
Sheet 6 actually shows the land between Ponds 2 &3 within Cell 2 and does not show the western boundary of Cell 2. All
excavation setbacks are greater than or equal to 47ft from the proposed pipelines.
2. Please have the permittee acknowledge the commitment to submitting a GW quality monitoring plan and
completing background sampling prior to exposing GW.
The permittee will commit to submitting a GW quality monitoring plan and completing background sampling prior to
exposing GW.
3. It's been my observation that settling ponds are usually associated with the plant area (control of wash water and
sediment) and not adjacent to the individual mining cells as shown on the map you just submitted. If this is the
case, please revise the map, or the permittee will need to submit a TR to show the location and extent of pond to
be associated with the plant, and account for its reclamation, prior to installing/using it.
The asphalt plant does not require a wash plant and therefore no settling pond is required at this point. If any settling,
detention or sediment ponds are required in the future, the permittee will file a TR to show the location and extent of this
facility(s), and account for its reclamation, prior to installing/using it.
4. Please revise/resubmit the first page of the application form to match the new acreage total given by moving the
permit boundary south and shown in the new legal description provided.
A revised page 1 of the application form has been attached.
5. Where will the facilities in Cell 6 (plant, etc.,) be located when Cell 6 is being mined?
The facilities in Cell 6 will be removed from the site prior to mining Cell 6. Page 7 of Exhibit D Mining Plan has been
updated to include this information. If this plan changes in the future a TR will be filed to define the new location and
account for required reclamation prior to the move.
6.A significant amount of backfill will be required to achieve the configuration shown on the reclamation plan. Has
there been any work done to establish that amount of material will be available from the operation, or will material
