MEMORANDUM
To: Kent Boyer, Division Environmental Officer, NCDOT Division 9
From: Amy Euliss
Subject: Site Visit Follow-up
NPDES Stormwater Permit NCS000250
Stokes Maintenance Facility
Stokes County
This memo is a follow-up to our site visit of the Camp Burton Maintenance Facility in Guilford County
on January 16, 2009. I appreciate the time you and Noel Chilton spent with Sue Homewood and myself
reviewing and discussing the NDPES Stormwater Permit for this facility.
The following items.are provided to help document ourjoint site visit efforts and to assist the Division
NCDOT staff.
A brief review of the Facility Stormwater Pollution Prevention Plan (SPPP) was conducted.
Documentation was exemplary regarding the SPPP. The SPPP has been updated yearly and BMPS are
being installed and documented as needed and as funding allows. Continued progress towards
implementation of recommended BMPs will be necessary.
Records of required training and routine inspections were available. There are eight stormwater outfalls
identified in the SPPP and site map. All outfalls are inspected each spring and fall as required by
NCS000250.
Flow from outfall 003 discharges into a wooded area and then into a UT to Flat Shoals Creek. Please
continue to monitor the area between the outfall and the stream to ensure that this area remains stable.
Between outfalls 003 and 004, a new outfall needs to be added due to changes in the topography
associated with recent grading. And finally at outfall 4, we recognize that establishing vegetation on the
soils has proven very difficult. Please continue your efforts to ensure that these sites are stable. It is
recommended that NCDOT staff walk the edges of the maintenance yard during low vegetation seasons
to ensure that additional point source discharges are not developing in any low areas around the yard.
Any sign of erosion channels forming should be addressed prior to any discharge reaching the creek.

Stokes Maintenance Yard Stormwater Review
January 30, 2009
In general, NCDOT the staff at the Stokes Maintenance Facility are aware of the stormwater permit and
requirements and have been conducting inspections and reporting as required. The Division would
recommend that the ditches below the outfalls should be routinely walked from the source of stormwater
to the UT to Flat Shoals Creek. This does not have to occur at the same time as the semi-annual outfall
inspections. Any indications that areas are continuously eroding, that the ditches are widening or
deepening, or that materials from the facility are being transported offsite by stormwater should be
addressed immediately.
Thank you again for the time you and other NCDOT staff took to conduct this site visit.
