Dear Mr. Lamb:

June 25, 2019
On April 24, 2019, Alaina Morman and Lauren Garcia, inspectors with the North
Carolina Department of Environmental Quality (NCDEQ) - Division of Energy, Mineral and
Land Resources (DEMLR), met with Ann McMillan, EH&S/ISO Manager, at the facility
located at 5618 Clyde Rhyne Drive, Sanford, Lee County, to conduct a compliance
inspection. The inspection consisted of reviewing: the Stormwater Pollution Prevention
Plan (SWPPP) and each of its components, the facility's outfalls, and the overall site
conditions. The inspection was conducted to ensure stormwater best management
practices are being followed, and to help fulfill NCDEQ's goal of inspecting all permitted
facilities during each permit period.
Permit:
This facility has Individual Stormwater Permit NCS000531 to discharge stormwater from
the industrial activity of manufacturing chemical adhesives [SIC 2891] under the National
Pollutant Discharge Elimination System (NPDES). The permit was originally issued on May
15, 2009, became effective on June 1, 2009, and expired on May 31, 2014.
Records/Reports:
The facility is required to develop and maintain a SWPPP in accordance with Part II, Section
A of the permit. All qualitative and analytical monitoring records are required to be
maintained with the SWPPP for a minimum of five years.
The facility provided all necessary records.
The facility is required to review and update the SWPPP on an annual basis in accordance
with Part II, Section A, Item, of the permit.
• The facility appeared to update the SWPPP on an annual basis. Inspectors
recommended that the SWPPP be updated with the current contact information.

Overall, the SWPPP was well put together and record keeping was very organized
and ready for NCDEQ to review.
Facility Site Review:
The facility manufactures chemical adhesives and monomers. The facility consists of one
main building, one warehouse, one wastewater pretreatment building, one flammable
storage building, an AST farm, a tote storage area, and a drum storage area.
• All materials, machinery, and tanks were stored/located within proper secondary
containment.
• The site appeared to be very well maintained.
There is one sampled outfall present at the facility, located to the southwestern corner of
the facility.
• The facility had recently performed maintenance to the outfall in response to a COD
benchmark exceedance, as it was believed the COD exceedance was caused by
overgrown vegetation.
Receiving Waters:
Stormwater at the site discharges to Little Buffalo Creek, a class C stream in the Cape Fear
River Basin. Little Buffalo Creek is an impaired waters experiencing problems with
benthos.
Self -Monitoring Program:
The facility is required to provide qualitative and analytical monitoring data twice
annually.
• The facility has monitored twice annually in accordance with the permit.
• Previous benchmark exceedances appear to have been addressed in accordance
with the permit.
The facility is considered to be in compliance. The facility provided all necessary records
and has upheld the conditions of the stormwater permit. If you have any questions or need
