We are working on two projects located in Saudi Arabia under LEED 2009 certification.

We are looking for finding the appropriate measures to be applied, as per EPA’s Construction General Permit and NPDES requirements, to match the intent of the SS Prerequisite 1.

We are aware about LEED Interpretation n.5114 (http://www.usgbc.org/leed-interpretations?keys=5114) which basically recognized minimal stormwater erosion concerns in case of desert area (“arid areas” as per EPA’s definition means an average annual rainfall of 0 -10 inches, Jeddah=2,1, Riyadh=4) and actually allows to avoid mitigation measures due to stormwater; so inspection could be conducted once a month, as per paragraph 3.10 of the CGP Fact sheet(http://water.epa.gov/polwaste/npdes/stormwater/upload/cgp2003_fs.pdf), instead of on weekly basis.

Regarding other items addressed within SSp1 we are wondering the following:

1) best way to manage the loss of soil due to wind, since sandstorm are very common for that climate, which actually make itself loss of soil other than fust.

2) best way to manage the air pollution from dust, considering that water availability could be an issue for that climate and therefore mitigation measure such as sprinkling would not be appropriate.

Do you have any advice/recommendation about those items, based on previous LEED certified projects located in KSA or similar climate?

Thank you.
