Dear Mr. Winston:
Mack Wiggins of the North Carolina Division of Water Quality, Surface Water Protection Section,

The following observations were made during the stormwater inspection:
This location at 630 United Drive primarily engages in distribution of industrial, and
specialty gases. This site does not perform any vehicle maintenance.

stormwater from the left parking area and bulk storage area. Outfall No. 2 receives
stormwater from the uncovered back dock and storage area and Ieft field. Outfall No. 3
receives stormwater from the back roof, dock and ramp area.
3. Qualitative monitoring was performed at the stormwater outfalls as required by NCS000046.
Recommend using the monitoring forms provided by the Division of Water Quality.
4. Analytical monitoring could not be retrieved at the time of the inspection. Analytical
monitoring must be performed as required by Part II, Section B of individual stormwater
permit NCS000046.
5. The Stormwater Pollution Prevention Plan contained all items as required by General Permit
NCS000050 with the exception of the feasibility study at the time of the inspection. The plan
has been implemented and is updated once a year.
