Hawaii Administrative Rules › Title 11 - DEPARTMENT OF HEALTH › Subtitle 1 - GENERAL DEPARTMENTAL PROVISIONS › Chapter 265 - HAZARDOUS WASTE MANAGEMENT INTERIM STATUS STANDARDS FOR OWNERS OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE AND DISPOSAL FACILITIES › Subchapter 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 an independent, qualified, registered
				  professional engineer in accordance with subsection 11-270-11(d) attesting that
				  the system has sufficient structural integrity and is acceptable for the
				  storing and treating of hazardous waste. This assessment must include, at a
				  minimum, 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.
(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.
