Dear All,

I am working on a project outside the US, where there are no local standards regarding ESC measures (the local codes are rather too general and do not address the requirements of this prerequisite).

I understand that we have to do an ESC plan. However, do all projects need to produce a StormWater Pollution Prevention Plan (SWPPP)?

What are the criteria to determine whether a SWPPP is required or not?

Thanks!
