Title 3745 - Ohio Environmental Protection Agency
Chapter 3745-66 - Closure and Post-Closure Under Interim Standards
Section 3745-66-92 - Design and installation of new tank systems or components
Current through all regulations passed and filed through December 16, 2024
(A) Owners or operators of new tank systems or components shall ensure that the foundation, structural support, seams, connections, and pressure controls (if applicable) are adequately designed and that the tank system has sufficient structural strength, compatibility with the wastes to be stored or treated, and corrosion protection so that the tank system will not collapse, rupture, or fail. The owner or operator shall obtain a written assessment reviewed and certified by a qualified professional engineer in accordance with paragraph (D) of rule 3745-50-42 of the Administrative Code attesting that the system has sufficient structural integrity and is acceptable for the storing and treating of hazardous waste. This assessment shall include the following information:
[Comment: The practices described in the "National Association of Corrosion Engineers (NACE)" standard, "Recommended Practice (RP-02-85) - Control of External Corrosion on Metallic Buried, Partially Buried, or Submerged Liquid Storage Systems," and the "American Petroleum Institute (API)" publication 1632, "Cathodic Protection of Underground Petroleum Storage Tanks and Piping Systems," may be used, where applicable, as guidelines in providing corrosion protection for tank systems.]
(B) The owner or operator of a new tank system shall ensure that proper handling procedures are adhered to in order to prevent damage to the tank system during installation. Prior to covering, enclosing, or placing a new tank system or component in use, an independent, qualified installation inspector or a qualified professional engineer, either of whom is trained and experienced in the proper installation of tank systems, shall inspect the system or component for the presence of any of the following items:
(C) New tank systems or components and piping that are placed underground and that are backfilled shall be provided with a backfill material that is a noncorrosive, porous, homogeneous substance and that is carefully installed so that the backfill is placed completely around the tank and compacted to ensure that the tank and piping are fully and uniformly supported.
(D) All new tanks and ancillary equipment shall be tested for tightness prior to being covered, enclosed or placed in use. If a tank system is found not to be tight, all repairs necessary to remedy the leaks in the system shall be performed prior to the tank system being covered, enclosed, or placed in use.
(E) Ancillary equipment shall be supported and protected against physical damage and excessive stress due to settlement, vibration, expansion, or contraction.
[Comment: The piping system installation procedures described in "American Petroleum Institute (API)" publication 1615 (November 1979), "Installation of Underground Petroleum Storage Systems," or ANSI standard B 31.3, "Petroleum Refinery System," may be used, where applicable, as guidelines for proper installation of piping systems.]
(F) The owner or operator shall provide the type and degree of corrosion protection necessary, based on the information provided under paragraph (A)(3) of this rule, to ensure the integrity of the tank system during use of the tank system. The installation of a corrosion protection system that is field fabricated shall be supervised by an independent corrosion expert to ensure proper installation.
(G) The owner or operator shall obtain and keep on file at the facility written statements by those persons required to certify the design of the tank system and supervise the installation of the tank system in accordance with the requirements of paragraphs (B) to (F) of this rule to attest that the tank system was properly designed and installed and that repairs, pursuant to paragraphs (B) and (D) of this rule, were performed. These written statements also shall include the certification statement as required in paragraph (D) of rule 3745-50-42 of the Administrative Code.
