Narrative: I received a report indicating the presence of suds I foam in a stream behind the Merritt Hinton Oaks
Development.The discharge was traced upstream,where a hose was observed actively discharging
waste/wash water from the neighboring Thomas Concrete Plant Flow appeared to be clear/greyish in
hue and had created a significant formation of foam&suds at the base of the slope. We immediately
flagged down the nearest site personnel,who contacted the main office Plant Manager,Mr. Bobby Corn.
Bobby was able to eliminate the discharge and explained that this system contained "recycled clean
water"being pumped from their main collection pit.This hose was typically used to wash down the
surrounding work area,before draining back towards the interior of the site. At this point the discharge
has ceased,but we informed Bobby we would need to circle back to our vehicles and meet back at the
plant office to inspect their NPDES Permit book. When we reached the office,Bobby informed us that
the area supervisor was on the way to evaluate the current site conditions. While we waited for his
arrival,Dylan and I looked through the NPDES book,which revealed some deficiencies with the current
inspections and overall record keeping. Bout 20 minutes passed before Mr, Sherwood Turner arrived to
discuss the offsite discharge. He informed us that no water should have been directed offsite,and that
that is not their current operating policy or procedure.Mr.Turner was able to get his group to remove the
pipe and hose system from that area and was in touch with a cleanup crew to determine if downstream
mitigation was possible. Being that the discharge was eliminated,and all discharge components were
relocated,the towns investigation was closed. This report along with photos captured during our
investigation will be forwarded to the NCDEQ NPDES program for further follow-up. Reported to
NCDEQ on 12-9-2022,with no response recieved.
