According to the EPA document, that is the case "If all of the storm water from the construction activity is captured on-site and allowed to evaporate, soak into the ground on-site, or is used for irrigation."If that describes your site, I would agree. However, this would be a very rare situation. Having a site with no stormwater controls where it's assumed that any water will soak in is not sufficient.

Hi, this is the answer of the USGBC about this topic: "It is not acceptable to simply state that all stormwater will be captured on-site and infiltrated or evaporated. Your SWPPP for this project must address all covered aspects anticipated to pertain to the project's construction activities (i.e. scope of work). On-site infiltration strategies can be part of an effective SWPPP as noted on page 14 of the document you cited: http://www.epa.gov/npdes/pubs/cgp2003_fs.pdf . Though on page 4 it is noted that projects that capture all stormwater on site do not require a permit (CGP), this LEED prerequisite, SSp1, requires projects to demonstrate compliance with the requirements of the referenced standard even when the standard would not typically be legally required by the jurisdiction having authority over the project (i.e. even in the case of sites that are less than 1 acre and sites in foreign countries).
