(a) IRRBP funds can be used to carry out PE, construction, and CE activities of projects to replace, rehabilitate, seismically retrofit, paint, apply calcium magnesium acetate, sodium acetate/formate or other environmentally acceptable, minimally corrosive anti-icing and deicing compositions, or install scour countermeasures for structurally deficient or functionally obsolete IRR bridges, including multiple pipe culverts.
