Hawaii Administrative Rules › Title 11 - DEPARTMENT OF HEALTH › Subtitle 1 - GENERAL DEPARTMENTAL PROVISIONS › Chapter 264 - HAZADOUS WASTE MANAGEMENT STANDARDS FOR OWNERS AND OPERATERS OF HAZADOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Subchapter J - TANK SYSTEMS › Section 11-264-192 - Design and installation of new tank systems or components

Current through June, 2024
(a) Owners or operators of new tank systems
				  or components must obtain and submit to the director, at time of submittal of
				  Part B information, a written assessment, reviewed and certified by an
				  independent, qualified registered professional engineer, in accordance with
				  subsection 11-270-11(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 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 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 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)
				  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.
(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 standards of
				  subsection 11-264-18(a); and
(iii)
				  Tank systems will withstand the effects of frost heave.
