On August 24, 2018 the EPA signed the Final Extension of the Short-Term National Product Waiver for Stainless-Steel Nuts and Bolts used in Pipe Couplings, Restraints, Joints, Flanges and Saddles. This short-term waiver permits the use of non-domestically produced stainless-steel nuts and bolts in bolting-type pipe couplings, restraints, joints, flanges, and repair saddles in iron and steel products for projects funded by the Clean Water or Drinking Water State Revolving Funds.
