Did … did you just double-dip that chip?.....

I'm working on a project that emphasizes the use of reclaimed materials and materials with recycled content and have come across a few items for which I'm unsure how to proceed with my LEED documentation. We are using many materials that qualify under both MR3 and MR4 credits and I'm wondering if I can apply the materials towards both credits. One example would be the use of steel angle from reclaimed electrical transmission towers. The steel angle obviously qualifies for 100% materials reuse, but it seems as if it should also be able to apply a standard 25% post-consumer recycled content value for the steel. Is this allowable?
