<br />§ 66265.192. Design and Installation of New Tank Systems
<br />or Components.
<br />(a) Owners or operators of new tank systems or components shall en-
<br />sure that the foundation, structural support, seams, connections, and
<br />pressure controls (if applicable) are adequately designed and that the tank
<br />system has sufficient structural strength, compatibility with the waste(s)
<br />to be transferred, stored or treated, and corrosion protection so that it will
<br />not collapse, rupture, or fail. The owner or operator shall obtain a written
<br />assessment reviewed and certified by an independent, qualified, profes-
<br />sional engineer, registered in California in accordance with section
<br />66270.11(d) attesting that the system has sufficient structural integrity,
<br />is acceptable for the transferring, storing and treating of hazardous waste,
<br />and that the tanks and containment system are suitably designed to
<br />achieve the requirements of this article. This assessment shall be ob-
<br />tained prior to placing the tank system in service, and shall be kept on file
<br />at the facility. This assessment shall also include, at a minimum, the fol-
<br />lowing information:
<br />(1) design standard(s) according to which the tank(s) and ancillary
<br />equipment are or will be constructed;
<br />(2) hazardous characteristics of the waste(s) to be handled;
<br />(3) for new tank systems or components in which the external shell of
<br />a metal tank or any external metal component of the tank system is or will
<br />be in contact with the soil or with water, a determination by a corrosion
<br />expert of:
<br />(A) factors affecting the potential for corrosion, including but not lim-
<br />ited to:
<br />1. soil moisture content;
<br />2. soil pH;
<br />3. soil sulfides level;
<br />4. soil resistivity;
<br />5. structure to soil potential;
<br />6. influence of nearby underground metal structures (e.g., piping);
<br />7. stray electric current; and,
<br />8. existing corrosion—protection measures (e.g., coating, cathodic pro-
<br />tection), and
<br />(B) the type and degree of external corrosion protection that are need-
<br />ed to ensure the integrity of the tank system during the use of the tank sys-
<br />tem or component, consisting of one or more of the following:
<br />1. corrosion—resistant materials of construction such as special alloys
<br />or fiberglass—reinforced plastic;
<br />2. corrosion—resistant coating (such as epoxy or fiberglass) with ca-
<br />thodic protection (e.g., impressed current or sacrificial anodes); and
<br />3. electrical isolation devices such as insulating joints and flanges;
<br />(4) for underground tank system components that are likely to be af-
<br />fected by vehicular traffic, a determination of design or operational mea-
<br />sures that will protect the tank system against potential damage; and
<br />(5) design considerations to ensure that:
<br />(A) tank foundations will maintain the load of a full tank;
<br />(B) tank systems will be anchored to prevent flotation or dislodgement
<br />where the tank system is placed in a saturated zone, or is located within
<br />a seismic fault zone; and
<br />(C) tank systems will withstand the effects of frost heave.
<br />(b) The owner or operator of a new tank system shall ensure that proper
<br />handling procedures are adhered to in order to prevent damage to the sys-
<br />tem during installation. Prior to covering, enclosing, or placing a new
<br />Waste
<br />§ 66265.192
<br />tank system or component in use, an independent, qualified installation
<br />inspector or an independent, qualified, professional engineer, registered
<br />in California, either of whom is trained and experienced in the proper in-
<br />stallation of tank systems, shall inspect the system or component for the
<br />presence of any of the following items:
<br />(1) weld breaks;
<br />(2) punctures;
<br />(3) scrapes of protective coatings;
<br />(4) cracks;
<br />(5) corrosion;
<br />(6) other structural damage or inadequate construction or installation.
<br />All discrepancies shall be remedied before the tank system is covered,
<br />enclosed, or placed in use.
<br />(c) New tank systems or components and piping that are placed under-
<br />ground and that are backfilled shall be provided with a backfill material
<br />that is a noncorrosive, porous, homogeneous substance and that is care-
<br />fully installed so that the backfill is placed completely around the tank
<br />and compacted to ensure that the tank and piping are fully and uniformly
<br />supported.
<br />(d) All new tanks and ancillary equipment shall be tested for tightness
<br />prior to being covered, enclosed or placed in use. If a tank system is found
<br />not to be tight, all repairs necessary to remedy the leak(s) in the system
<br />shall be performed prior to the tank system being covered, enclosed, or
<br />placed in use.
<br />(e) Ancillary equipment shall be supported and protected against
<br />physical damage and excessive stress due to settlement, vibration, expan-
<br />sion or contraction.
<br />(f) The owner or operator shall provide the type and degree of corro-
<br />sion protection necessary, based on the information provided under sub-
<br />section (a)(3) of this section, to ensure the integrity of the tank system
<br />during use of the tank system. The installation of a corrosion protection
<br />system that is field fabricated shall be supervised by an independent cor-
<br />rosion expert to ensure proper installation.
<br />(g) The owner or operator shall obtain and keep on file at the facility
<br />written statements by those persons required to certify the design of the
<br />tank system and supervise the installation of the tank system in accor-
<br />dance with the requirements of subsections (b) through (f) of this section
<br />to attest that the tank system was properly designed and installed and that
<br />repairs, pursuant to subsection (b) and (d) of this section were performed.
<br />These written statements shall also include the certification statement as
<br />required in section 66270.11(d) of this division.
<br />(h)(1) Notwithstanding subsections (a) through (g) of this section, de-
<br />sign and installation of new tank systems or components used to manage
<br />hazardous waste, and which meet the criteria specified in subsection
<br />(h)(2) of this section, are not subject to the requirements of subsections
<br />(h) through (m) of this section until January 24, 1998. The assessment
<br />specified in subsection (k) of this section shall be obtained prior to plac-
<br />ing a new tank system in service and shall be kept on file at the facility.
<br />This assessment shall be reviewed and certified by an independent, quali-
<br />fied, professional engineer, registered in California, in accordance with
<br />section 66270.11(d), attesting that the tank system has sufficient structur-
<br />al integrity and is acceptable for the transferring, storing and treating of
<br />hazardous waste. The assessment shall be valid for a maximum period
<br />of five (5) years or the remaining service life of the tank system, as stated
<br />in the engineer's assessment, whichever is less. New tank systems that
<br />have been assessed pursuant to subsections (a) through (g) of this section
<br />prior to June 1, 1995 are not required to be reassessed pursuant to subsec-
<br />tion (k) for a period of five years from the date of the assessment or June
<br />1, 2000, whichever is the earlier date. If changes have been made to the
<br />tank system or new components have been added to the tank system sub-
<br />sequent to an assessment conducted prior to June 1, 1995, the tank system
<br />shall be reassessed pursuant to subsection (k).
<br />(2) The provisions of subsection (h)(1) of this section apply only to:
<br />(A) onground or aboveground tank systems containing only non—
<br />RCRA hazardous waste generated onsite, and tank systems authorized
<br />under Permit—by—Rule pursuant to Chapter 45 of this division, Condi-
