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 £ill 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
