In the California Construction General Permit, Minimum BMPs refer to

• A. Optional BMPs
• B. Maximum BMPs by region
• C. Specific BMPs only for residential projects
• D. Required minimum BMPs by level/type

Answer: (D)

Minimum BMPs are the baseline erosion and sediment controls that the California Construction General Permit requires you to implement, and these baselines are scaled to the project’s level or type. They aren’t optional practices or regional maximums; they are the mandatory minimum measures that must be in place and maintained throughout the project. In practice, you choose the minimum set appropriate for your project’s size and type and use that as the foundation for your SWPPP and site controls. The other options don’t fit because the permit’s minimums aren’t optional, aren’t regional maxima, and aren’t restricted to residential projects.
