IV. ENFORCEMENT ACTIONS
Colowyo C-1981-019
23 July 2008
Page 2/2 6D-01c:?
Missing from Colowyo's original submittal, and included as an adequacy question in
the Divisions PAR letter, were SEDCAD runs documenting that the Section 16 Pond
was able to meet the requirements of Rule 4.05.9(2) for the 25-year, 24-hour storm
event. This omission is critical, as Colowyo's proposed extension of the Section 16
Pond Ditch would increase the disturbed area reporting to the Section 16 Pond by
approximately 23 acres.
On the inspection it was found that Colowyo had already constructed the entire
Section 16 Pond Ditch extension before any proposed decision, publication or public
comment period had been completed. A review of aerial photographs taken on 29
May 2008 by Harry Ranney indicates that work on the Section 16 Pond Ditch
extension began as early as that date. The area has been grubbed and possibly
had the topsoil removed.
Based on the above information, the Division has determined that Colowyo is in
violation of the following Rules:
Rule 2.08.4(4): The operator may not implement any permit revision, technical
revision, or minor revision before obtaining final approval.
Rule 2.05.3(4): Ponds, impoundments, other treatment facilities and diversions... A
general plan and detailed design plan shall be submitted for each sediment pond,
impoundment, other treatment facility and diversion proposed to be constructed within
the permit area.
Rule 4.05.9(2): All impoundment spillway systems shall provide for either a combination
of principal and emergency spillways, or a single spillway configured as required by
4.05.9(2) (a), designed to safely pass the applicable design precipitation event specified
in 4.05.9(2)(c)...
Please review Rules 5.03 and 5.04 regarding the enforcement procedures and penalties
for more information regarding the Notice of Violation process.
NOTE: Attach appropriate VIOLATIONS or CESSATION ORDER CODING FORMS
