Code of Maryland Regulations › Title 26 - DEPARTMENT OF ENVIRONMENT › Part 3 - SUBTITLES 13-18 › Subtitle 13 - DISPOSAL OF CONTROLLED HAZARDOUS SUBSTANCES › Chapter 26.13.05 - Standards for Owners and Operators of Hazardous Waste Treatment, Storage, and Disposal Facilities › Section 26.13.05.10-3 - Design and Installation of New Tank Systems and Components

Current through Register Vol. 51, No. 14, July 12, 2024
A. The owner or
				  operator of a new tank system may not manage hazardous waste in the tank system
				  unless the written assessment required by § B(1) of this regulation
				  demonstrates to the Secretary's satisfaction 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 or wastes to be stored or treated, and
				  corrosion protection to ensure that it will not collapse, rupture, or
				  fail.
B. Owners or operators of new
				  tank systems or components shall:
(1)
				  Demonstrate, through a written assessment reviewed and certified by an
				  independent, qualified, registered professional engineer, in accordance with
				  COMAR 26.13.07.03 o D, that the tank
				  system has sufficient structural integrity and is acceptable for the management
				  of hazardous waste;
(2) Include, at
				  a minimum, in the assessment required by § B(1) of this regulation, the
				  following information:
(a) Design standard or
				  standards according to which the tank system and ancillary equipment will be
				  constructed;
(b) Hazardous
				  characteristics of the waste or wastes to be managed;
(c) 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 soil moisture
				  content, soil pH, soil sulfides level, soil resistivity, structure to soil
				  potential, influence of nearby underground metal structures such as piping,
				  existence of stray electric current, existing corrosion protection measures
				  such as coating or cathodic protection; and
(ii) The type and degree of external
				  corrosion protection that are needed to ensure the integrity of the system
				  during the use of the system or component, consisting of corrosion-resistant
				  materials of construction such as special alloys, fiberglass reinforced
				  plastic, corrosion-resistant coating such as epoxy or fiberglass, with cathodic
				  protection such as impressed current or sacrificial anodes, or electrical
				  isolation devices such as insulating joints or flanges;
(d) 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
(e) Design
				  considerations to ensure that tank:
(i)
				  Foundations will maintain the load of a full tank;
(ii) Systems will be anchored to prevent
				  flotation or dislodging where the tank system is placed in a saturated zone, or
				  is located within a seismic fault zone subject to the standards of
				  40 CFR §
														264.18(a); and
(iii) Systems will withstand the effects of
				  frost heave;
(3) Submit to the Secretary the written
				  assessment required by §B(1) of this regulation as part of the owner's or
				  operator's application for a Controlled Hazardous Substances facility permit or
				  permit modification;
(4) Comply
				  with the following requirements for installation of new tank systems:
(a) Ensure that proper handling procedures
				  are adhered to in order to prevent damage to the system during
				  installation;
(b) Before covering,
				  enclosing, or placing a new tank system or component in use, have the tank
				  system inspected by an independent, qualified installation inspector or an
				  independent, qualified, registered professional engineer, either of whom is
				  trained and experienced in the proper installation of tank systems or
				  components, for the presence of any of the following items:
(i) Weld breaks,
(ii) Punctures,
(iii) Scrapes of protective
				  coatings,
(iv) Cracks,
(v) Corrosion, and
(vi) Other structural damage or inadequate
				  construction or installation;
(c) Remedy all discrepancies detected in the
				  inspection required by §B(4)(b) of this regulation before the tank system is
				  covered, closed, or placed in use;
(5) Use a backfill material that is a
				  noncorrosive, porous, homogeneous substance for new tank systems or components
				  that are placed underground and that are backfilled, and install the backfill
				  material so that the backfill is placed completely around the tank and
				  compacted to ensure that the tank and piping are fully and uniformly
				  supported;
(6) Test all new tanks
				  and ancillary equipment for tightness before covering, enclosing, or placing in
				  use;
(7) Perform all repairs
				  necessary to remedy any leaks in the tank system before covering, enclosing, or
				  placing the system into use;
(8)
				  Ensure that ancillary equipment is supported and protected against physical
				  damage and excessive stress due to settlement, vibration, expansion, or
				  contraction;
(9) Provide the type
				  and degree of corrosion protection recommended by an independent corrosion
				  expert, based on the information provided under the requirements of §B(2)(c) of
				  this regulation, or other corrosion protection if the Secretary believes other
				  corrosion protection is necessary to ensure the integrity of the tank system
				  during its use;
(10) Ensure that
				  the installation of a corrosion protection system that is field-fabricated is
				  supervised by an independent corrosion expert to ensure proper
				  installation;
(11) Obtain and keep
				  on file at the facility written statements by the persons required to certify
				  the design of the tank system in accordance with §B(1) and (2) of this
				  regulation and the persons required to supervise the installation of the tank
				  system in accordance with the requirements of §B(4)-(10) of this regulation
				  that attest that the tank system was properly designed and installed, and that
				  repairs required by §B(4)(c) and (7) of this regulation were
				  performed;
(12) Include, in the
				  written statements required by §B(11) of this regulation, the certification
				  statement as required in COMAR
				  26.13.07.03 o D.
