Per the facility's Stormwater Pollution Prevention Plan (SWPPP), stormwater samples were collected from two locations (Sampling Point 01 and Sampling Point 02) and analyzed for total suspended solids (TSS), chemical oxygen demand (COD) and pH. North Carolina's Benchmark Values for these analytes are 100 milligrams per liter (mg/L), 120 mg/L, and 6.0 — 9.0 standard units (S.U.), respectively. The sample locations and designations shown within the Drainage Area Site Map for the facility are included as an attachment to this response letter. While the results of the TSS and COD analyses for the sampling points did not result in a Benchmark Value exceedance, pH was reported above North Carolina's Benchmark Value of 9.0 S.0 at each of the two sampling points. The pH value for Sample Point 01 was 9.83 S.U. and the pH value for Sample Point 02 was 9.85 S.U. BSI Project No. 972213 Annazon.com Services LLC Tier One Response 021822 North Carolina Department of Environmental Quality, 610 East Center Avenue, Suite 301 Page 2 Photos Sample Point 01 Field pH Sample Point 02 Field pH The facility has implemented the following responses as a result of the pH exceedances in accordance with Table 3, Section E-5 of North Carolina's General Permit NCG060000: • The exceedance and sampling date will be recorded within the facility's SWPPP. • The North Carolina Department of Environmental Quality, Division of Energy, Mineral, and Land Resource's Regional Office will receive the transmission of this letter (via email), a copy of which will be recorded within the facility's SWPPP. • An inspection of the site was completed on February 4, 2022 to, in part, identify any potential sources of stormwater impacts from the facility. • The site inspection did not identify an obvious source of the elevated pH recorded at the site. It was noted, though, that road salt had been used across the industrial areas of the site for de-icing purposes and as road salt has a mineral content, dissolved road salts in stormwater runoff can be "hard water", or high in mineral content, and have an elevated pH as a result. • The recommended action for the facility is to resample in Quarter 2 of 2022, which should be free of the effects of dissolved road salt, and evaluate data and initiate corrective actions should pH concentrations in excess of Benchmark Values persist. Please do not hesitate to contact me should you have questions or require additional information regarding the above outlined Benchmark Value exceedance or Tier One Response/Action plan.
