Re: Colorado Mined Land Reclamation Division's (MLRD) Response Dated
December 19, 1990, to Ten-Day Notice (TDN) 90-02-370-001, TV2, Coal
Basin Mine C-81-017
Dear Mr. Mathews:
The Albuquerque Field Office (AFO) of the Office of Surface Mining
Reclamation and Enforcement (OSM) received the above-referenced final
response on December 26, 1990. AFO has reviewed MLRD's written and oral
responses to this TDN and renders the following finding in accordance
with 30 CFR 842.11(b) (1) (ii) (B) (1) :
Violation 1 of 2
AFO has previously notified MLRD that its response as amended was
appropriate. The operator was required to submit the demonstration
documentation within the 30-day time period.
Violation 2 of 2
AFO understands from the written and oral responses that: (1) A
revision to the Coal Basin permit was approved on or about December 21,
1990. This revision addresses the mine water discharge that was a
subject of the TDN; (2) this revision requires the operator to screen
the mine water in the mine to filter the coarse materials from the
water, use flocculent chemical treatment of the mine water at the Rock
Tunnel mouth, and route the water through pond No. 020 prior to
discharge into Coal Creek. In case of clean-out or an emergency, the
discharge will be routed to the No. 001 pond prior to discharge into
Coal Creek. The No. 016 pond will only receive the mine water in case
the other sedimentation ponds referenced above become dysfunctional for
