I have a question regarding the Regional Materials Credit: If a product has
the following components:

- Cement (local product)
- Sand (local product)
- Additives (imported)

Will this product comply although the Additves are not regional? Additives
are used in very small quanitites in the overall product and are not
considered to be: extracted, harvested or recovered, however I would like to know how the USGBC will evaluate this.

Thanks!
