Option 1 in the Material Ingredients credit references a specific threshold for reporting when using the pathway for Health Product Declarations. This threshold was called, “full disclosure of known hazards” in HPD v1. HPD v2 was released September 10, 2015 and the standard no longer includes this threshold designation. To meet the same level of disclosure of HPD v1, a version 2 HPD must:
· List substance name and CAS RN, role or function, amount, and health hazards for every substance at or above 1000 ppm in the finished product for Option 1, 100 ppm for Option 2; name and CAS RN may be withheld for ingredients defined as trade secret or intellectual property, but role, amount, and hazards must be reported.
· Indicate whether residuals and impurities were considered, with explanation as required in the HPD Open Standard.
HPD v2 provides two formats for reporting – Basic Inventory and Nested Material and Substance. Either can be used for LEED. If using the Basic Inventory format, the manufacturer must report all substances in the final product to a threshold of at least 1,000 ppm by weight for Option 1 or 100 ppm for Option 2.
If using the Nested Material and Substance format, the inventory is still relative to the final product for the purposes of LEED. Since this format is reporting the inventory of each material rather than the final product, it is possible that a product with the boxes checked the "Per GHS" or "Per OSHA” boxes could still be compliant, even if the "1000 ppm of per material" box is unchecked. In this scenario, manufacturers should note in the Inventory and Screening Notes that all ingredients over 1000 ppm or 100 ppm of the product are disclosed. The Nested Material and Substance format also can be used as specified in the HPD Open Standard, with the threshold specified for each material to be at least 1000 ppm in each material for Option 1 and 100 ppm in Option 2. The Nested Material and Substance format also can be used as specified in the HPD Open Standard, with the threshold specified for each material to be at least 1000 ppm in each material for Option 1 and 100 ppm in Option 2.
