RE: Mid-Continent Resources NPDES Permit Renewal Application
As requested, I have reviewed the NPDES permit renewal application submitted by Mid-
Continent Resources to Water Quality Control Division. The following comments pertain to the
submittal.
Cover Letter Page 2, and recurring throughout the document: In many places throughout the
document, Mid-Continent Resources (MCR) states that Minerals and Geology (DMG) reclaimed
a number of access or haul roads, and as a result of this activity, the ponds located near the upper
reaches of these roads are no longer accessible. Minerals and Geology accomplished reclamation
of Roads E, F and G, which provide access to Mines 3 and 5, and of the uppermost one half mile
of the access road to Mines 1 and 2 in 1996. Reclamation construction consisted of removal of
virtually all road drainage culverts, changing the slope of the road from the inside to the outside,
construction of numerous water bars, deep ripping of the road remnant, and revegetation. The
mines located at the top of these roads are accessible by horse back, by foot, by bicycle and by all
terrain vehicle. Mid-Continent employees, consultants, and contractors have accessed these
mines via all terrain vehicle subsequent to reclamation being accomplished. Furthermore,
contractors to Mid-Continent accessed Mines 3 and 5 vicinities via the reclaimed roads using a
large track loader (similar to a bull dozer) in 1997.
Permit Application Form, Page 3, Flow Measurement: It is possible that some of the flow from
the 016 discharge point is flowing around, rather than through, the parshall flume located below
the discharge point.
Permit Application Form, Page 3, Land Application: Minerals and Geology, the agency
accomplishing reclamation of the site, has no plans to land apply discharges from the Rock
Tunnel. Minerals and Geology has planned to construct a channel to convey the flow from the
Rock Tunnel to Dutch Creek. Water Quality Control Division was consulted about this concept
in 1996. Issues regarding WET testing were not resolved between Water Quality and Mid-
Continent, therefore, diversion of the flow to Dutch Creek was not undertaken at that time. The
