Hello everyone,

we have a office building in Vienna Austria). I am wondering if we have to do an SWPPP.

According to the EPA Fact Sheet http://www.epa.gov/npdes/pubs/cgp2003_fs.pdf (Site 4) a construction site doesn´t fall under the EPA-permit if all the storm water from construction activity is captured on-site and allowed to evaporate, soak into the ground on-site.

So does ist means if we have a construction site were we allow the storm water to soak into the ground, we don´t have to write a Storm Water Pollution Prevention Plan for LEED and we only have to document this and do the ESC-plan (Erosion, Dust)?

Does anyone knows?
Thanks for helping.
