• All iron or steel articles, materials, or supplies must be produced entirely in the U.S. (from initial melting

through coatings).

to Buy America.

amended by the Resource Conservation and Recovery Act). This requires purchasing EPA-designated items

(40 CFR Part 247) that contain the highest practicable percentage of recovered materials, consistent with

satisfactory competition. This applies when the item’s purchase price exceeds $10,000 or when County

purchases of that item exceeded $10,000 in the previous fiscal year. Covered categories include paper

products, vehicular products, construction and transportation products, park and recreation products,

landscaping products, non-paper office products, and miscellaneous products.
