Discharge
Gentlemen,
I appreciate you keeping me in the loop on this matter. We do not consider coal fines as
being a regulated discharge of fill material. However, the clean up work will likely
require permitting. I've included a permit checklist and application, along with
nationwide permit summaries for NW27 and NW33. If the creation of the temporary catchment
basin(s) can be conducted via excavation only, i.e. without placing any material within
the stream or adjacent wetlands, the creation will not require permitting. The
restoration of the stream would require permitting. The catchment basin should be placed
outside of wetlands, to the maximum extent practicable, and any wetlands that cannot be
avoided should be excavated in such a way that the top 12-18 inches of topsoil will be
stockpiled seperately from the sub-soil. During restoration the sub-soil should be placed
first with the topsoil spread back on top. In order to ensure a stable stream reach after
restoration, a longitudinal profile of the stream should be taken at the area of the
proposed catchment basin prior to excavation. Please feel free to contact me with any
questions. Thank you.
Sincerely,
Nathan Green
