OBSERVATIONS
PERMIT #: M- 1985 -218
INSPECTOR'S INITIALS: TC1
INSPECTION DATE: April 10, 2012
This was a Succession of Operator (SO) inspection for the purpose of determining if the current financial
warranty is adequate. The operator's representative (Rusty Cochran) was present for the inspection. This site is
located approximately nine miles east of Pueblo, in Pueblo County. The site is south of US Highway 50 on the
north bank of the Arkansas River.
Inspection:
The Permit sign and boundary markers were properly posted (Photo 1). The site has not been actively mined
for several years, but Mr. Cochran indicated stockpiled material is occasionally sold and transported offsite.
Protection of the Arkansas River bank was discussed and if the Operator had addressed possible stream capture
by the active pit. Mr. Cochran showed this inspector the U.S. Army Corps of Engineers (USACE) permit for
"Hard Point Protection" in the Arkansas River. The permit allows the Operator to build scour protection
structures, such as bendway weirs in the river to protect the river bank.
Records:
• The previous inspection was conducted 12/20/2007.
• Division records indicate a substitute water supply plan was approved by the Division of Water
Resources through March 31, 2012 for the exposed groundwater on site.
• The permit anniversary date is June 15. The operator is current with annual fees and reports through
2011.
• This is the third SO for the site. Lafarge SO'd the site from SO Western Mobile Southern, Inc. in 2002.
Bond:
The current $51,542 bond is inadequate to cover the cost of installing a slurry wall as proposed by the previous
Operator's consultant (Applegate Group, Inc) in a letter dated April 28, 2011 (see enclosure). This is cited as a
problem on page 1 of this inspection report. The Operator may phase in the increased bond if desired. A photo
of the pond is included as Photo 4.
Recommendations:
The Division recommends the following tasks be completed by the Operator:
1. The previous substitute water supply plan (SWSP) expired at the end of March 2012. The Operator
needs to renew /amend the SWSP with the Division of Water Resources. The Operator should also
verify all water rights necessary for the SWSP were transferred to the Operator during the transfer of the
property. The source of replacement water is the Arkansas Groundwater Users Association (AGUA).
2. The Operator shall submit a Technical Revision to the Division requesting a change to the reclamation
plan to include the slurry wall proposed by the Applegate Group. The lack of a permit revision for the
slurry wall is cited as a problem on page 1 of this inspection report.
3. The Operator should note that if there is no mining related activity for 180 days or more, a request for
Temporary Cessation should be submitted to the Division pursuant to C.R.S. 34- 32.5 -103 (11) (b).
