2010 SF Reduced Risk Pesticde List

Andy, There's a Reference Guide addenda that directs project teams to the SF Pesticide Hazard Screening List: http://www.sfenvironment.org/our_programs/interests.html?ssi=2&ti=1&ii=117 It's my understanding that this is more comprehensive than the Reduced Risk Pesticide lists (regardless of issue date). Also, the Pesticide Hazard Screening List includes Tier 1 and 2 products in addition to Tier 3, so make sure you are zeroing in on the right Tier.

My query is related to above. Will the LEED Review team consider chemicals on the list if concentrations/dilutions are lower than those on the list? Hoping to hear some advise. thanks

The Hazard Screening List will indicate that the threshold for Tier 1/Tier2/Tier 3 is sometimes based on a minimum concentration of the active ingredient (i.e. 7.9% by volume). If the product you're using isn't listed on the Hazard Screening List, but the active ingredient is listed, you'll need to show that your product has a concentration equal to or lower than the concentration for a Tier 3 product. so if the ingredient shows up as a Tier 1 pesticide with a concentration of 5.0%, it isn't enough to show that your product has a concentration of 4.9% - you need to show that your product meets Tier 3 thresholds.
