American Iron and Steel Provision

American Iron and Steel (“AIS”) Provision

Recent EPA funding provisions for water and waste water infrastructure projects include a restriction against using the funds to purchase certain iron or steel products that were produced outside the United States. Specifically, the funding provision requires Clean Water State Revolving Loan Fund and Drinking Water State Revolving Loan Fund assistance recipients to …

“…use iron and steel products that are produced in the US for projects for the construction, alternation, maintenance, or repair of a public water system or treatment works.”

This provision is known in the industry as the American Iron and Steel (or “AIS”) requirement. EPA’s guidance on the AIS requirement specifically mentions valves made of iron and steel.

At the time you request a quote, please notify us if the product you will be purchasing will be required to meet the new AIS requirement.
