NPDES General Industrial Permit
Industry sectors must update site-specific SWPPPs to comply with the 2023 NPDES General Permit. Here’s how.

 

On July 1, 2023, the Illinois Environmental Protection Agency (IEPA) posted and updated General NPDES Permit No. ILR00 for Industrial Storm Water Discharges (2023 General Permit). The 2023 General Permit is effective July 1, 2023, through June 30, 2028.

Multiple industry sectors must now update their site-specific Storm Water Pollution Prevention Plan (SWPPP) to comply with the 2023 General Permit. Three key updates in the 2023 General Permit are:

1-Permittees are required to submit a Notice of Intent (NOI) for renewal no later than 150 days after the 2023 General Permit is issued (i.e., by November 28, 2023).

2-Permittees must place a sign of permit coverage (except in instances where other laws or local ordinances prohibit such signage) in a safe, publicly accessible location in close proximity to the facility and include the following:

      • The NPDES ID Number;
      • Information about how the public can request the facility’s SWPPP; and
      • How to contact the facility and IEPA if stormwater pollution is observed.

3-Benchmark sampling requirement updates, varying based on the industry sector’s Standard Industrial Classification (SIC) Code classification:

      • Certain SIC Code groups will be required to re-evaluate existing benchmark sampling constituent thresholds (See the list of these SIC Code groups below, titled List 1); and
      • Certain SIC Code groups will have new reporting requirements associated with constituents for which a benchmark threshold has not been established (See the list of these SIC Code groups below, titled List 2).
