Re: Second Review of a 112 Construction Materials Reclamation Permit Amendment Application Package
AM03,Bestway Concrete Company,Permit M1998-013
Mr. Rodriguez:
The Division of Reclamation, Mining, and Safety has completed its second adequacy review of your 112
construction materials reclamation permit amendment application. The application was called complete for review
on February 19, 2020. All comment and review periods began February 19, 2020. The decision date for this
application is May 19 2020. Please be advised that if you are unable to satisfactorily address any concerns
identified in this review before the decision date, it will be your responsibility to request an extension of the
review period. If there are outstanding issues that have not been adequately addressed prior to the end of
the review period, and no extension has been requested, the Division will deny this application. In order to
allow the Division adequate time to review your responses to any adequacy issues, please submit your
adequacy responses to the Division no later than one week prior to the decision date (May 12,2020).
Please note that any changes or additions to the application on file in our office must also be reflected in the
public review copy, which has been placed with the Weld County Clerk and Recorder.
The review consisted of comparing the application content with specific requirements of Rule 6.1, 6.2, 6.4 and 6.5
of the Minerals Rules and Regulations of the Colorado Mined Land Reclamation Board for the Extraction of
Construction Materials. As with most applications,there are items that will require clarification of the existing
information. Any inadequacies are identified under the respective exhibit heading.
EXHIBIT L -Reclamation Costs (Rule 6.4.12): All information necessary to calculate the costs of reclamation
must be submitted and broken down into the various major phases of reclamation. You must provide sufficient
information to calculate the cost of reclamation that would be incurred by the state.
DRMS will require additional information to be included in the reclamation estimate provided. At this time,
DRMS notes that the mining plan states that Cells 2A and 3 will be mined at 2:1 slopes,but no volumes or costs
have been provided for backfilling from 2:1 to the required final 3:1 internal slopes; please also provide the linear
feet of slurry wall, and perimeter distances requiring backfill for these excavations.
Also per our previous discussion, DRMS will need additional information on the following items:backfill of the
settling pond areas, (existing settling area for shores looks closer to 22 acres); additional information for
backfilling of cells 1 and 2B -how much fill needed for each,where the material is coming from and what it's
going to cost to move it from it's current location to where it needs to be utilized; backfill of infiltration area north
of Pond E; an acreage breakdown for ripping, topsoil replacement, and revegetation around each pond and
