Re: Follow-up on Pre-Construction Notification of (Exempt) Temporary Mining Haul Roads
3M Facility in Pittsboro, North Carolina
Dear Mr. Thomas and Mr. St. John:
On May 9, 2000, we sent a letter notify you of the pre-construction of (exempt) temporary mining haul
roads at the 3M property in Pittsboro, NC. Two temporary haul roads for moving mining equipment on the
Pittsboro site, are subject to the federal exemption of 40 CFR 232.2 (c.) (6) (i-xv). In a May 24`x' meeting,
you requested some additional information on these haul roads.
As we noted in our May 9`h letter, these two haul roads will be associated with the mining/aggregate
operations and will be constructed on a temporary basis for purposes of establishing the mining site, and
later they will be upgraded to permanent roads. The temporary roads will be minimum widths with culvert
crossings, headwalls, outlet protection, and 2:1 side fill slopes. Mining haul road #1 will be 100' top width
initially and later upgraded to 140' top width with a conveyor crossing. Mining haul road #2 will be 76'
top width initially and upgraded with safety berms later. When the temporary haul roads are upgraded to
permanent haul roads, then the proper 404/401 permits will be secured.
If the temporary haul roads are necessary to close in the future, then the reclamation plan would be the
following: 1) provide temporary erosion and sediment control measures during removal, 2) remove the
road fill, 3) remove the culverts, and 4) restablize and vegetate the stream side slopes using seeding no. 2P
from the mining reclamation plan.
With this letter, 3,'v1 is requesting your written approval of construction of the (exempt) temporary haul
roads for moving mining equipment. If you have any questions about this request, please contact me at the
above address or call me at [phone]. icy
Sincerely, r
