Pursuant to the requirement of Rule 1. 13.6 of the Rules and Regulations of the Colorado Mined Land
Reclamation Board to inform Counties and Municipalities within two miles of a mining operation of the
intention of mining operators to put their mining operation into a state of temporary cessation of mining,
please be advised that Aggregate Industries - WCR, Inc., whose address and telephone number are 1707
Cole Blvd., Ste. 100 , Golden, CO 80401; [phone], has filed a Notice of Temporary Cessation with
the Division of Reclamation, Mining and Safety for the Lyons Quarry mining operation. The mining
operation is located at or near Section 26, Township 3N, Range 71 W, 06th Prime Meridian, in Boulder

years from that date. In addition, the operator may request an extension of temporary cessation for another
five year period at the end of the first five years. The notice contains information pertaining to the reasons
for cessation of the mining operation, a plan for resumption, and the measures taken to comply with
reclamation and other necessary activities related to the performance standards of Rule 3 of the Rules and
Regulations in order to maintain the mine in a non-producing or non-development state.
The receipt of the Notice of Temporary Cessation will be acknowledged in the monthly activity report
attached to the agenda of the February 9th, 2011 meeting of the Mined Land Reclamation Board unless one
or more of the following conditions occurs:
1. Reclamation or performance standard issues are indicated in the Notice of Temporary
Cessation.
2. Such issues are indicated by a field inspection of the mine site.
3. Such issues are indicated by a review of the mining operation file.
4. Concerns are expressed about the Notice of Temporary Cessation by interested persons.
If one or more of the above conditions occurs, the Division will place the Notice of Temporary Cessation

meeting, the Board will consider whether or not to accept the Notice. If you have any questions, please
