Hawaii Administrative Rules › Title 11 - DEPARTMENT OF HEALTH › Subtitle 1 - GENERAL DEPARTMENTAL PROVISIONS › Chapter 265.1 - HAZARDOUS WASTE MANAGEMENT: INTERIM STATUS STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Part 265 - INTERIM STATUS STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Subpart J - Tank Systems › Section 11-265.192 - Design and installation of new tank systems or components

Current through June, 2024
(a)
					 Owners or operators of new tank systems or components must 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) to be stored or treated,
					 and corrosion protection so that it will not collapse, rupture, or fail. The
					 owner or operator must obtain a written assessment reviewed and certified by a
					 qualified Professional Engineer in accordance with § 270.11(d) of this
					 chapter attesting that the system has sufficient structural integrity and is
					 acceptable for the storing and treating of hazardous waste. This assessment
					 must include the following information:
(1)
					 Design standard(s) according to which the tank(s) and ancillary equipment is or
					 will be 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 is or will be in contact with the soil or with water, a
					 determination by a corrosion expert 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)
					 Stray electric current; and,
(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 or
					 fiberglass-reinforced plastic;
(B)
					 Corrosion-resistant coating (such as epoxy or fiberglass) with cathodic
					 protection (e.g., impressed current or sacrificial anodes); and
(C) Electrical isolation devices such as
					 insulating joints and flanges.
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 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 dislodgement where the tank system is placed in a saturated zone,
					 or is located within a seismic fault zone; and
(iii) Tank systems will withstand the effects
					 of frost heave.
