inlet and outlet facilities. If the location of these structures needs to be changed in the future, it
can be done through a Technical Revision to the permit.
Inlets and outlet design and locations for the reservoirs are not known at this time and will be
determined near the conclusion of extraction activities as a part of final reclamation. The
applicant agrees to provide the location and design of inlet and outlet facilities as a Technical
Revision prior to release of the lands from the approved permit.
27. The Reclamation Plan includes a backfill notice and affidavit certifying that the material
is clean and inert. Please specify the areas that will be backfilled. Will buildings or other
structures be constructed on backfill areas? If so, how will the material be placed and stabilized
to prevent settling and voids?
The application Backfill Permit, states:
`Material will be minced with on-site processing fines and reject prior to fill to
eliminate void spaces, where necessary.'
Fill will include `inert materials' that are not reactive with water or saturated conditions.
Essentially, Varra Companies will comply with all solid waste regulations as specified in 6 CCR
1007-2, PART 1. Varra Companies will only use inert materials which meet the following
definition taken from the aforementioned regulation: "Inert material" means non-watersoluble
and non-putrescible solids together with such minor amounts and types of other materials as will
not significantly affect the inert nature of such solids. The term includes, but is not limited to,
earth, sand, gravel rock, concrete which has been in a hardened state for at least sixty days,
masonry, asphalt paving fragments, and other inert solids.
The use of fill is part of the reclamation effort and is anticipated to be utilized along perimeter
locations where extraction narrows or is shallow, for example at basin corners and notches.
Since it is difficult to identify the exact location and extent of fill locations in advance, final fill
locations will be mapped as part of reclamation and the information provided to the Office at the
time the applicant requests release from the permit.
Any structures located over fill will include the necessary engineering evaluation and local
permitting approval prior to construction. Structures over fill will not occur during the life of the
112 permit, except for any portions of the permit area released in part by the Office, or where
otherwise approved by the Office under a Technical Revision to the approved permit.
