Re: Permit No. C-81-071. Notice of Violation CV-97-012
Dear Mr. Gorham;
RECEIVED
AUG 1 1 19g~
Division of Minerals & Neology
Sediment Pond inspection reports were not completed for the sediment ponds associated
with Permit No. C-81-071 for the second quarter of 1997. The NOV was written as
"Failure to conduct second quarter, 1997 pond inspections as required by Rule
4.05.6(13)." With regard to sediment pond inspections, Rule 4.05.6(13) states:
"All sedimentation ponds shall be examined by a qualified registered
professional engineer or other qualified individuals under their direction.
The professional engineer or individual shall be experienced in the
construction of sedimentation ponds. Ponds shall be inspected for
structural weakness, erosion, and other hazardous conditions. The report
shall also include the level of the sediment in the pond and any other
required maintenance of the structure. These inspections shall be made
regularly during construction, upon completion of construction, and at a
minimum, on a quarterly basis thereafter. The report shall be retained at
or near the mine site and a copy of the report promptly submitted to the
Division on a quarterly or annual basis, as required by the Division, by a
registered professional engineer"
CYCC feels that the requirements of this rule were met for the second quarter; however,
the report forms were not completed nor on file at the time of the DMG inspection due to
an oversight. The following information is provided with regard to NOV CV-97-012.
Each of the ponds associated with the NOV aze visited on a weekly basis to collect
samples as required by NPDES permit CO-0027154. Visual inspections with regard to
any structural problems, erosion, or hazardous conditions would be noted and repairs
scheduled for the pond, if necessary. A registered professional engineer, experienced in
