§ 66264.192. Design and Installation of New Tank Systems or Components.
Currentness
(a) Tanks shall have sufficient shell strength and, for closed tanks, pressure controls (e.g., vents) to assure that they do not collapse or rupture. The Department will review the design of the tanks, including the foundation, structural support, seams and pressure controls and seismic considerations. The Department shall require that a minimum shell thickness be maintained at all times to ensure sufficient shell strength. Factors to be considered in establishing minimum thickness include the width, height and materials of construction of the tank, and the specific gravity of the waste which will be placed in the tank. In reviewing the design of the tank and approving a minimum thickness, the Department shall rely upon appropriate industrial design standards and other available information.
(b) Owners or operators of new tank systems or components shall obtain and submit to the Department, at time of submittal of Part B information, a written assessment, reviewed and certified by an independent, qualified professional engineer, registered in California, in accordance with section 66270.11(d), attesting that the tank system has sufficient structural integrity and is acceptable for the transferring, storing and treating of hazardous waste and that the tanks and containment system are suitably designed to achieve the requirements in this article. The assessment shall 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 transferred, 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, shall also 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:
(A) factors affecting the potential for corrosion, including but not limited to:
1. soil moisture content;
2. soil pH;
3. soil sulfides level;
4. soil resistivity;
5. structure to soil potential;
6. influence of nearby underground metal structures (e.g., piping);
7. existence of stray electric current;
8. existing corrosion-protection measures (e.g., coating, cathodic protection), and
(B) 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:
1. corrosion-resistant materials of construction such as special alloys, fiberglass reinforced plastic, etc.;
2. corrosion-resistant coating (such as epoxy, fiberglass, etc.) with cathodic protection (e.g., impressed current or sacrificial anodes); and
3. 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;
(5) design considerations to ensure that:
(A) tank foundations will maintain the load of a full tank;
(B) 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 section 66264.18(a); and
(C) tank systems will withstand the effects of frost heave; and
(6) those design requirements and factors listed in subsection (a) of this section.
(c) The owner or operator of a new tank system shall ensure that proper handling procedures are adhered to in order to prevent damage to the system during installation. Prior to covering, enclosing, or placing a new tank system or component in use, an independent, qualified installation inspector or an independent, qualified, professional engineer, registered in California, either of whom is trained and experienced in the proper installation of tank systems or components, shall inspect the system for the presence of any of the following items:
(1) weld breaks;
(2) punctures;
(3) scrapes of protective coatings;
(4) cracks;
(5) corrosion;
(6) other structural damage or inadequate construction/installation.
All discrepancies shall be remedied before the tank system is covered, enclosed, or placed in use.
(d) New tank systems or components that are placed underground and that are back filled shall be provided with a backfill material that is a noncorrosive, porous, homogeneous substance and that is installed so that the backfill is placed completely around the tank and compacted to ensure that the tank and piping are fully and uniformly supported.
(e) All new tanks and ancillary equipment shall be tested for tightness prior to being covered, enclosed, or placed in use. If a tank system is found not to be tight, all repairs necessary to remedy the leak(s) in the system shall be performed prior to the tank system being covered, enclosed, or placed into use.
(f) Ancillary equipment shall be supported and protected against physical damage and excessive stress due to settlement, vibration, expansion, or contraction.
(g) The owner or operator shall provide the type and degree of corrosion protection recommended by an independent corrosion expert, based on the information provided under subsection (b)(3) of this section, or other corrosion protection if the Department believes other corrosion protection is necessary to ensure the integrity of the tank system during use of the tank system. The installation of a corrosion protection system that is field fabricated shall be supervised by an independent corrosion expert to ensure proper installation.
(h) The owner or operator shall obtain and keep on file at the facility written statements by those persons required to certify the design of the tank system and supervise the installation of the tank system in accordance with the requirements of subsections (c) through (g) of this section, that attest that the tank system was properly designed and installed and that repairs, pursuant to subsections (c) and (e) of this section, were performed. These written statements shall also include the certification statement as required in section 66270.11(d) of this division.
(i)(1) Notwithstanding subsections (b) through (h) of this section, design and installation of new tank systems or components used to manage hazardous waste, and which meet the criteria specified in subsection (i)(2) of this section, are not subject to the requirements of subsections (i) through (n) of this section until January 24, 1998. The assessment specified in subsection (l) of this section shall be obtained prior to placing a new tank system in service and shall be kept on file at the facility. This assessment shall be reviewed and certified by an independent, qualified, professional engineer, registered in California, in accordance with section 66270.11(d), attesting that the tank system has sufficient structural integrity and is acceptable for the transferring, storing and treating of hazardous waste. The assessment shall be valid for a maximum period of five (5) years or the remaining service life of the tank system, as stated in the engineer's assessment, whichever is less. New tank systems that have been assessed pursuant to subsections (b) through (h) of this section prior to June 1, 1995 are not required to be reassessed pursuant to subsection (l) for a period of five years from the date of the assessment or June 1, 2000, whichever is the earlier date. If changes have been made to the tank system or new components have been added to the tank system subsequent to an assessment conducted prior to June 1, 1995, the tank system shall be reassessed pursuant to subsection (l).
