RE: Adequacy Review - Lohmann Sand and Cravel one -File No. Af--2001-017
Dear Ms. Mayer:
Listed below are the Division's adequacy review comments on the Lohmann 112 construction materials
permit application.
On page 11 of the application, the applicant stated that the design information, technical specifications, CQA
procedures and a sample construction report for the proposed slurry wall would be submitted during the DMG
112 review process. The Division anticipates that the same information will be submitted for the proposed
clay liner. Since this information has not been received, adequacy comments on the slurry wall, clay liner and
related reclamation costs cannot be included in this review.
The current decision due date for this application is June 18, 2001. Please be advised that your application
may be deemed inadequate and may be denied on June 18, 2001, unless the following adequacy review items
are addressed, along with any adequacy review items that arise from the yet to be submitted slurry wall and
clay liner information.
If additional time is needed to prepare and submit an adequacy response, the applicant may waive their right
to a decision within 90 days and request an extension of time. However, such a request must be made in
writing and received by the Division on or before June 18, 2001.
The following items need to be addressed as part of this adequacy review:
1) Rule 6.2(2) requires that "Maps, except the index map, must conform to the following
criteria:
bJ must be prepared and signed by a registered land s:~rveyor, professionnl
engineer or other qualifred person ".
Please provide the Division with a set of maps with the appropriate signatures.
2) On page 10 of the application, Exhibit E-Reclamation Plan, it is stated that imported inert fill
will be used as part of the reclamation.
Please provide the Division with the information required under Rule 3.1.5(9) (a) through (f),
concerning the backfilling of structural fill material generated outside of the approved permit
area.
