Are LUP projects subject to the post-construction standards in the CGP?

• A. No
• B. Only if they disturb more than 1 acre
• C. Only if they are industrial facilities
• D. Yes

Answer: (D)

Post-construction stormwater controls under the Construction General Permit are meant to apply to any project that falls under CGP coverage, including LUP projects. Once a site is subject to the CGP, it must implement and maintain post-construction BMPs to prevent polluted runoff after construction is finished. This requirement isn’t limited only to large industrial facilities or to projects above a certain size in isolation; it addresses how land-use changes can affect drainage and water quality over the long term. Therefore, LUP projects are subject to the post-construction standards in the CGP.
