The Colorado Department of Public Health & Environment -Water Quality Control Division ~9ree,~~`
("WQCD") Durango District Office conducted a routine compliance inspection of the wastewater
treatmeni facility ("W WTF°) for the Sunnyside Gold Mine-American Tunnet on September 26,
2002.
Participants of the inspection included Larry Perino (Sunnyside Gold) and Gregory Brand
(WQGD-Durango). Enclosed is a copy of the inspection report for your records.
During the inspection, the following items were noted and need to be brought to your attention:
No deficiencies and no problems were noted during the inspection.
2. Sunnyside Gold anticipates the final closing of the American Tunnel in late 2002 or early
2003. Sunnyside Gold plans to place the third (last) of three plugs to seal the American
Tunnel. After the last plug is placed, Sunnyside Gold anticipates that mine drainage
from the American Tunnel will cease.
3. The Sunnyside Gold Consent Decree is currently under review for modification andlor
amendment. Upon completion of the amendment, Sunnyside Gotd cuttentfy anticipates
transferring the American Tunnel Discharge Permit and ownership of the wastewater
treatment facility ("WWTF°) to Gold King Mines, Inc. (Silverton, Colorado). Sunnyside
Gold stilt needs to adequately satisfy the requirements of their Colorado Division of
Minerals and Geology Recamation Permit. Sunnyside Gold anticipates that reclamation
activities will be complete by Tate 2003 or 2004.
4. The hydraulic loading on the treatment facilities during the time of inspection was approx.
280 gpm (of mine drainage) plus approx. 1200 gpm (of Cement Creek stream flow) for a
total hydraulic loading of approx. 1480 gpm or 2.1 MGD (million gallons per day). The
treatment process consists of; pH adjustment with hydrated lime addition, flocculent
addition, flow through a series of 4 settling ponds, with discharge into Cement Creek
which flows into the Animas River.
