South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-79 - Hazardous Waste Management Regulations › Part 61-79.264 - STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Subpart J - TANK SYSTEMS › Section 61-79.264.J.192 - Design and installation of new tank systems or components

Current through Register Vol. 48, No. 6, June 28, 2024
(a) Owners or
				  operators of new tank systems or components must obtain and submit to the
				  Department at time of submittal of Part B information, a written assessment,
				  reviewed and certified by a qualified Professional Engineer, in accordance with
				  R.61-79.270.11(d)(d)attesting that the tank system has sufficient structural
				  integrity and is acceptable for the storing and treating of hazardous waste.
				  The assessment must 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
				  Department 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 tank
				  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 export of:
(i) Factors affecting the potential for
				  corrosion, including but not limited to:
(A)
				  Soil moisture content;
(B) Soil
				  pH;
(C) Soil sulfides
				  level;
(D) Soil
				  resistivity;
(E) Structure to soil
				  potential;
(F) Influence of nearby
				  underground metal structures (e.g., piping);
(G) Existence of stray electric
				  current;
(H) Existing
				  corrosion-protection measures (e.g., coating, cathodic protection),
				  and
(ii) 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:
(A)
				  Corrosion-resistant materials of construction such as special alloys,
				  fiberglass reinforced plastic, etc.;
(B) Corrosion-resistant coating (such as
				  epoxy, fiberglass,etc.) with cathodic protection (e.g., impressed current or
				  sacrificial anodes); and
(C)
				  Electrical isolation devices such as insulating joints, flanges, etc. (amended
				  11/90)
[Note: 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
(i) Tank
				  foundations will maintain the load of a full tank;
(ii) Tank systems will be anchored to prevent
				  flotation or dislodgment where the tank system is placed in a saturated zone,
				  or is located within a seismic fault zone subject to the standard of 264.18(a);
				  and
(iii) Tank systems will
				  withstand the effects of frost heave.
