Posted on July 18, 2023

North Carolina

On June 1, 2023, the North Carolina Department of Environmental Quality (DEQ) released a new NPDES permit for stormwater discharges from industrial activities in the Apparel, Printing, Leather, Rubber, and Miscellaneous Manufacturing industries (NCG05000). This covers facilities with Standard Industrial Classification Codes (SIC) 23xx, 27xx, 267x, 265x, 39xx, 31xx, and 30xx. This permit has several notable revisions including the new requirement for baseline analytical monitoring and the additional requirement for a Solvent Management Plan. Beginning in 2023, baseline analytical monitoring is required quarterly at all sites for Total Suspended Solids (TSS), pH, and Chemical Oxygen Demand (COD). Feasibility studies are no longer required in the SWPPP. In addition, a Solvent Management Plan is to be added in the SWPPP if a facility uses, receives, stores, or disposes of solvents. Current permittees that did not previously have baseline analytical monitoring will start monitoring in 2024. This allows time to prepare for monitoring requirements and eDMR registration.
