Ohio Admin. Code 3745-66-92 - Design and installation of new tank systems or components

(A) Owners or operators of new tank systems or components must 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 waste(s) wastes to be stored or treated, and corrosion protection so that it the tank system will not collapse, rupture, or fail. The owner or operator must 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 must shall include the following information:
(1) Design standard(s) standards according to which the tank(s) tanks and ancillary equipment is or will be constructed, .
(2) Hazardous characteristics of the waste(s) wastes to be handled, .
(3) For new tank systems or components in which the external shell of a metal tank or any external metal component of the tank system is or will be in contact with the soil or with water, a determination by a corrosion expert of:
(a) Factors affecting the potential for corrosion including but not limited to:
(i) Soil moisture content;
(ii) Soil pH;
(iii) Soil sulfides level;
(iv) Soil resistivity;
(v) Structure to soil potential;
(vi) Influence of nearby underground metal structures (e.g., piping);
(vii) Stray electric current; and
(viii) Existing corrosion-protection measures (e.g., coating, cathodic protection); and
(b) The type and degree of external corrosion protection that are needed to ensure the integrity of the tank system during the use of the tank system or component, consisting of one or more of the following:
(i) Corrosion-resistant materials of construction such as special alloys, fiberglass-reinforced plastic;
(ii) Corrosion-resistant coating (such as epoxy, or fiberglass) with cathodic protection (e.g., impressed current or sacrificial anodes); and
(iii) Electrical isolation devices such as insulating joints and flanges.

[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.]

(4) For underground tank system components that are likely to be affected by vehicular traffic, a determination of design or operational measures that will protect the tank system against potential damage, ; and
(5) Design considerations to ensure that:
(a) Tank foundations will maintain the loan load of a full tank;
(b) Tank systems will be anchored to prevent flotation or dislodgement where the tank system is placed in a saturated zone, or is located within a seismic fault zone; and
(c) Tank systems will withstand the effects of frost heave.
(B) The owner or operator of a new tank system must 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, must shall inspect the system or component for the presence of any of the following items:
(1) Weld breaks;
(2) Punctures;
(3) Scrapes of protective coatings;
(4) Cracks;
(5) Corrosion; and
(6) Other structural damage or inadequate construction or installation. All discrepancies shall be remedied before the tank system is covered, enclosed, or placed in use.

All discrepancies must be remedied before the tank system is covered, enclosed, or placed in use.

(C) New tank systems or components and piping that are placed underground and that are backfilled must 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 must 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 leak(s) leaks in the system must shall be performed prior to the tank system being covered, enclosed, or placed in use.
(E) Ancillary equipment must 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 must 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 must field fabricated shall be supervised by an independent corrosion expert to ensure proper installation.
(G) The owner or operator must 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 must also shall include the certification statement as required in paragraph (D) of rule 3745-50-42 of the Administrative Code.
