Is the RO concerned that the operation, as proposed, would violate standards of water quality?
Comments:
Steel Gray Mine project area is located within the French Broad Watershed, adjacent to the North Toe River (Classification C; Tr).
Protected trout waters have a turbidity standard of 10 NTU. Runoff, sediment discharge, or actions contributing to an increase of turbidity exceeding 10
NTU within surface waters may constitute as a violation of water quality standards.
Best management practices and vegetative buffers should be used to ensure runoff and storm water discharge does not entering surface waters.
2021 aerial imagery shows minimal vegetation within the 25 ft trout buffer. Establishing a fully vegetated buffer and implementing adequate and regularly
maintained sediment control measures is essential to minimizing the impacts of potential sediment releases to the N. Toe River.

DEMLR Permit: 61-19
Applicant: Blue Ridge Quarries / Buechel Stone Corp.
Project Name: Steel Gray Mine
General Comments:
Steel Gray Mine project area is located within the French Broad Watershed, adjacent to the North Toe
River (Classification C; Tr). Protected trout waters have a turbidity standard of 10 NTU. Runoff, sediment
discharge, or actions contributing to an increase of turbidity exceeding 10 NTU within surface waters
would constitute as a violation of water quality standards.
Best management practices and vegetative buffers should be used to ensure runoff and storm water
discharge does not enter surface waters.
2021 aerial imagery shows minimal vegetation within the 25 ft trout buffer. Establishing a fully
vegetated buffer and implementing adequate and regularly maintained sediment control measures is
essential to minimizing the impacts of potential sediment releases to the N. Toe River.
Plan Specific Comments:
Overburden and stockpile sites were not indicated on received site plans.
Plans indicate a discharge point into N Toe River, labeled "Outfall 01". Section C(3)B within the permit
application refers to discharge into surface waters. Applicant must ensure to secure appropriate permits
for such discharge.
"Sediment and storm water ponds" indicated on site plans are located within the 1% annual chance
floodplain. Locating sediment and storm water ponds within the floodplain may result in washout and
sediment loss into surface waters during extreme flooding events.
Operation and maintenance plans for sediment ponds were not received with submission. The
implementation of BATS and BCTs is highly recommend to ensure strict compliance with turbidity
standards and monitoring requirements of the required storm water permit (NCG020000). Maintaining
and operating all measures is key to protecting water quality.
