Hawaii Administrative Rules › Title 11 - DEPARTMENT OF HEALTH › Subtitle 1 - GENERAL DEPARTMENTAL PROVISIONS › Chapter 264.1 - HAZARDOUS WASTE MANAGEMENT: STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Part 264 - STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Subpart 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 a qualified Professional Engineer, in accordance with
					 § 270.11(d) of this chapter, 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.
[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 standards of § 264.18(a); and
(iii) Tank systems will withstand the effects
					 of frost heave.
