Ohio Administrative Code › Title 3745 - Ohio Environmental Protection Agency › Chapter 3745-55 - Corrective Action, Closure, Post-Closure, and Financial Requirements › Section 3745-55-92 - Design and installation of new tank systems or components

Current through all regulations passed and filed through July 1,
			 2024
(A) Owners or
			 operators of new tank systems or components must obtain and
			 submit to the director, at time of submittal of "Part B" information, 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 tank system has sufficient
			 structural integrity and is acceptable for the storing and treating of
			 hazardous waste. The assessmentmust show 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) to be stored or treated, and corrosion
			 protection to ensure that it will not collapse, rupture, or fail. This
			 assessment, which will be used by the director to review and approve or
			 disapprove the acceptability of the tank system design,
			 must
			 include, at a minimum, the following information:
(1) Design standard(s) according to which
			 tank(s) and/or the ancillary equipment are constructed;
(2) Hazardous characteristics of the waste(s)
			 to be handled;
(3) For new systems
			 or components in which the external shell of a metal tank or any external metal
			 component of the tank system 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)
			 Existence of 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, etc.;
(ii) Corrosion-resistant coating
			 (such as epoxy, fiberglass, etc.) with cathodic protection (e.g., impressed
			 current or sacrificial anodes); and
(iii) Electrical isolation devices such as
			 insulating joints, flanges, etc.
[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 adversely 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 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 subject
			 to the standards of rule
			 3745-54-18 of
			 the Administrative Code; and
(c)
			 Tank systems will withstand the effects of frost heave.
