Shannon
Thank you for taking the time to walk us around the Roxboro and Mayo Plant. Here are my
observations.
With regard to the Roxboro Facility:
• One pipe, a 10 to 12 inch corrugated pipe had not been previously identified, led from a low
spot adjacent to the ware house, ran under the fence, and day lighted just past the fence.
The discharge from the pipe fed a heavily vegetated area without a defined point source. I
concur that this pipe is not a point source discharge.
• SW -A and SW-3 are properly identified as point source discharges associated with industrial
activities. I concur that we should take another look at the analytical monitoring
requirements for PCBs, Copper, Selenium, Mercury and Zinc. The area did not contain
electrical equipment or oil storage.
• No other stormwater discharges were observed during the site visit.
With regard to the Mayo Facility:
• 1 concur that it would be appropriate to include Outfall 004 and Outfall 005 under the
wastewater permit rather than the stormwater permit. Non-stormwater flow was observed
from Outfall 004 and Outfall 005 during the site visit.
• Outfall 010 should remain as a stormwater point source discharge associated with industrial
activities as long as the access road is being used to deliver chemicals and other materials.
• Outfall 006a appears to be a stormwater point source discharge associated with industrial
activities.
• Outfall 006b does not appear to be a stormwater point source discharge. The discharge
from the Outfall 006b fed a heavily vegetated area without a defined point source.
• 1 concur that it would be appropriate to include Outfall 006c, Outfall 006d, and Outfall 006e
under the wastewater permit rather than the stormwater permit.
• No other stormwater discharges were observed during the site visit.
