Steel sub listed 76.60% of raw materials extracted within 500 miles of project, the data he provided for back-up lists 5 different locations where the raw material was extracted but manufacturer cannot specify which individual location that particular material was extract - and they are not all within 500 miles - How do I figure the mileage?? And why does the EBMCF form ask for percentages of material extracted yet Leed Online is looking for actual mileage ? Thanks.
