The Division of Reclamation, Mining and Safety received the Technical Revision Application 03 (TR-03) to the
Three Bells Pit, Permit No. M-1979-191. The Division has the following items that need to be addressed prior to
approval of the revision.
1. Please provide a signed letter from Lafarge West, Inc. authorizing TST, Inc. Consulting
Engineers to submit TR-03 on their behalf.
2. Rule 6.2.1(2) requires that maps be signed by a registered land surveyor, professional engineer, or
other qualified person. The maps submitted to the Division were not signed. Please resubmit a
signed copy of the maps.
3. The map submitted with the application (titled Exhibit E) depicts an area that is not well defined
within the approved 360 acre permit area. The Division printed out the mining and reclamation
maps approved in 1979 and highlighted the approved permit boundary. The Division was unable
to determine from the map submitted with TR-03 where it relates to in the approved permit area.
Please submit a map or revise the map to identify the location within the approved permit area.
4. Exhibit E contains contour elevations for both existing and reclaimed areas. However, with both
contour lines on the map it is difficult to decipher which is which. In addition, the contour lines
on the northeast corner of the site stop midway and do not connect to any other contour lines.
Please submit a separate map depicting the existing contour elevations and the reclaimed contour
elevations. Please also include the contour elevations on both maps.
5. The operator notes a ditch re-aliglment on the western side of the map. Please state the ditch to
be relocated. If Lafarge intends to mine through and relocate a ditch, they will need to submit a
notarized agreement between the operator and the owner(s) of the ditch allowing this to occur.
Please submit a notarized agreement or comply with Rule 6.4.19 as it relates to mining within 200
feet of permanent man made structures.
6. Please submit engineered drawings and designs of the re-aligned ditch.
7. Please locate on the map all existing permanent man made structures within 200 feet of the
affected land. In accordance with Rule 6.4.19, if mining or reclamation is to occur within 200
feet of a structure Lafarge must either;
