; (ii) protective coatings; (iii) materials selection; (iv) cathodic protection; (v) corrosion engineering; (vi) personnel training; and (vii) best practices in environmental protection to prevent environmental degradation and uphold public health; and (B) require certified contractors, for the purpose of carrying out aspects of applicable bridge projects described in paragraph (2), to employ a substantial number of individuals that are trained and certified by a qualified training program. (4) Certification For an applicable bridge project that includes an aspect described in paragraph (2), the entity carrying out the project shall only accept bids from a certified contractor that presents written proof that the certification of the contractor meets the relevant SSPC–QP standards (or a successor standard). (c) Training program As a condition of entering into a contract for an applicable bridge project, each certified contractor shall provide training for each individual who is not a certified coating applicator but that the certified contractor employs to carry out aspects of applicable bridge projects described in subsection (b)(2). 3. Availability of Federal grant funding for corrosion control work on rail bridges Section 22402(b)(1) of title 49, United States Code, is amended— (1) in subparagraph (E), by striking or at the end; (2) by redesignating subparagraph (F) as subparagraph (G); and (3) by inserting after subparagraph (E) the following: (F) to perform corrosion control work on rail bridges; or . 4. Study on efficacy of weathering steel (a) Findings Congress finds that— (1) weathering steel is often used for bridge construction projects because of its ability to withstand weather conditions better than other forms of steel; (2) the recent collapse of the Fern Hollow Bridge in Pittsburgh, Pennsylvania, in January 2022 highlights the real threat that corrosion poses to the bridges of the United States; (3) more research is needed into the vulnerabilities of weathering steel
