The Division has received a request from Colorado Yampa Coal Company (CYCC) to
vacate NOV C-99-008 issued for failure to conduct hydrologic monitoring in accordance
with the approved plan. Coincident with the request, we have received additional
information concerning the NOV.
Background
The Division issued NOV C-99-008 to CYCC for failure to conduct hydrologic
monitoring in accordance with the approved plan on September 7, 1999. The Annual
Hydrology Report (AHR) is required to be submitted to the Division by January 31 of
each year for the water year ending in September of the previous year. The 1998 AHR
was received by the Division on June 15, 1999. Page 8-8 of Exhibit 8 of the approved
permit application requires monitoring of three spoil wells, 026-SP-1, 026-SP-2 and
026-SP-3. This monitoring is to occur on a quarterly frequency for water level and field
parameters, and on asemi-annual basis for full suite laboratory analysis.
Rationale
On page 4 of the 1998 CYCC AHR text, the operator states "The fall 1997 water quality
sampling of these wells (spoil wells) was inadvertently missed." Upon review of the
data, not only was the fall visit for field parameters and laboratory sampling missed, but
the next visit in March, and the subsequent visit in May, also did not include a
laboratory sample as required. Therefore, staff made the decision to take the
enforcement action.
