Ill. COMMENTS -COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. supports a cover of shrubs and grasses which is rather sparse, but comparable to adjacent undisturbed areas. Given the erosional stability of the embankment, and the presence of mature vegetation, additional vegetative stabilization efforts would not appear to be warranted. The operator has contracted with an engineering firm to conduct required stability analyses. The work can apparently not be conducted until late April, necessitating an extension for final abatement of NOV C-97-001, which had originally been set at April 1, 1997. The abatement deadline has been extended to April 23, 1997, which is the 90th day following issuance of the NOV. The operator has submitted a request for extension of the abatement deadline beyond the 90th day, to allow for completion of the stability analyses, submittal of adequacy responses to the Division, and the to day public comment period following DMG approval. The request has been forwarded to the Division Director for authorization. Pond 4 -- Dry. The operator indicated that an issue arose during the CDPS permit renewal which is currently in progress regarding the location of Pond 4 discharge. Although the pond seldom holds water and has never discharged, if it were to discharge, flow would potentially enter the adjacent irrigation canal. Preliminary indications are that the ditch company may not authorize discharge into the canal, and if so, Powderhorn would need to submit a revision to construct a ditch to convey discharge to the Coal Creek drainage, or otherwise bypass the canal. Pond 6 -- Dry. Pond 10 -- Dry. Pond 11 -- Dry. Pond 1/2 -- Small puddles. Pond 7 -- Dry. Pond 9 -- Dry. Pond 8 -- Water level appeared to be approximately 5 feet - below the spillway elevation. There was a small inflow (approximately 2-3gpm) entering the pond on March 31. Source of the inflow was drainage from the Roadside South Portal, which was entering the drop inlet drain on the portal bench and draining into the pond. The water was draining from a sump within the mine which had filled due to a pump which malfunctioned over the weekend. Repairs to the pump were being undertaken at the time of the inspection.
