Good afternoon,
This email serves to formally notify your office that a stormwater sample collected from Outfall 002 at Joseph T.
Ryerson&Son, Inc. (5435 Hovis Rd, Charlotte, NC 28208)on February 16,2026,exceeded the benchmarkfor zinc,
with a measured concentration of 0.141 mg/L.
After investigating their outdoor storage areas,the site identified the likely sources as coil cradles stored near the
outfall,traffic,and asphalt degradation in the adjacent parking lot.The coil cradles have since been covered with
tarps. Furthermore, the facility will review and reinforce good housekeeping practices with staff to help prevent
future occurrences.The site will continue to monitor outdoor storage areas for any other potential sources.
All details of this Tier One response, including the exceedance date and value, inspection date, personnel
involved, actions taken, and implementation dates,will be formally documented in the Stormwater Pollution
Prevention Plan (SWPPP).
