RE: JD-8 Mine, Permit No. M-1984-014, Notice of Required Environmental Protection Plan (EPP)
Amended.
Dear Mr. Williams,
Cotter Corporation legal consul has raised a question regarding dates of compliance for issues at the JD-
8 Mine. The original letter sent out on October 21, 2010 noted dates of compliance that were based off
the inspection report created the previous day while the letter noted actions were required by the date
of the letter. The Division of Reclamation, Mining, and Safety (the Division) is clarifying that the due
dates for compliance are from the date of the original letter, October 21, 2010 not the dates noted in
the report. Staff regrets any confusion on the issue and is giving Cotter the extra day created by the
error. Therefore, please review and note the amended dates of compliance noted below.
On September 23, 2010 the Division of Reclamation, Mining, and Safety (the Division) inspected the JD-8
Mine as part of its normal monitoring program. The JD-8 Mine is a 112-d, Designated Mining Operation
(DMO) permit. The Division notes the existence of a stockpile of 300 to 500 tons of uranium ore that
has been on site since at least April 2, 2008. At that time, the Division requested that the stockpile be
enclosed by berms to prevent stormwater interaction and to contain ore sedimentation. The
September 2010 inspection noted that the berms were not placed or had been removed. Site
conditions noted the interaction with stormwater and sedimentation fans from or near the stockpile
that suggested ore fines were potentially leaving the immediate area.
As an interim measure, the Division required Cotter to immediately install berms completely around the
stockpile to prevent further excursions of sedimentation and interaction with stormwater. The task was
completed within 30 days of the original letter, November 17, 2010. Division staff verified the berms
were in place on the 17th.
