Hi Elizabeth, Proprietary blends are tricky! If the proprietary portion is made of sodium chloride or calcium chloride, but is less than 5% of the total product, the deicer is compliant. If the product has more than 5% sodium chloride/calcium chloride (or if the manufacturer documentation is unclear and the product COULD have over 5%), the product is considered non-compliant. You could also check out LEED Interpretation 10146 which lays out some alternative compliance paths.

Hi Trista, Do you know if it is no more than 5% total, or 5% per product (eg. is a product that includes 4% CaCl and 3% NaCl compliant)? Thanks.

Hi Tracy, it's 5% total for non-compliant ingredients. So your example of a product that contains 7% CaCl and NaCl would not be considered environmentally preferred.

Thanks, Trista! Does anyone happen to know a good product that is compliant? Seems like it's a tough one to actually find in stores, and you have to pay quite a bit in shipping if you purchase online...any tips would be much appreciated!

Did you ever find a compliant product? I am dealing with this right now.  Thanks!

Hi Tracy/Jessica - agreed, it can be hard to find something compliant through typical procurement options. Many of the "environmentally friendly" deicers available through companies like Grainger and Home Depot do not meet LEED requirements. There may be options online that have lower shipping costs, but you have to search around and see what can be delivered to your area. I found this site online (https://greenicemelt.com) but haven't used it so certainly can't say I personally recommend it. It's more of an example of what's out there if you do some digging. Good luck!

Hello, Is anyone aware if the interpretation applies for LEEDv4/v4.1 projects?  Thank you
