Calcium Magnesium Acetate?

Our purchasing team recently bought an ice melter that contains Calcium Magnesium acetate, which is not one of the three options that LEED specifies. However, the product is "EPA Design for the Environment Recognized and Readily Biodegradable Per OECD Or ASTM Standards"...It is my understanding that this will still not comply with this credit - what are your thoughts? Thanks so much for any insight...

Elizabeth, My understanding is that the examples provided in the RG is not to be an exhaustive list of environmentally-preferred deicers, so I'd recommend focusing on a option that is demonstratively better that either sodium chloride or calcium chloride. Given that calcium magneisum acetate is know to be minimally corrosive and it's biodegradable, I would consider it to be a compliant option.
