Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 724 - STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Subpart J - TANK SYSTEMS › Section 724.292 - Design and Installation of New Tank Systems or Components

Current through Register Vol. 48, No. 28, July 12, 2024
a) Owners or operators of new tank systems or
				components must obtain and submit to the Agency, at time of submittal of Part B
				information, a written assessment, reviewed and certified by a qualified
				Professional Engineer, in accordance with 35 Ill. Adm. Code
				702.126(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 wastes 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 Agency to review and
				approve or disapprove the acceptability of the tank system design, must
				include, at a minimum, the following information:
1) Design standards according to which tanks
				or the ancillary equipment are constructed;
2) Hazardous characteristics of the wastes 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 the following:
A) Factors affecting the potential for
				corrosion, including but not limited to the following:
i) Soil moisture content;
ii) Soil pH;
iii) Soil sulfide level;
iv) Soil resistivity;
v) Structure to soil potential;
vi) Influence of nearby underground metal
				structures (e.g., piping);
vii)
				Existence of stray electric current;
viii) Existing corrosion-protection measures
				(e.g., coating, cathodic protection, etc.); 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:
i) Corrosion-resistant materials
				of construction, such as special alloys, fiberglass reinforced plastic,
				etc.;
ii) Corrosion-resistant
				coating, such as epoxy, fiberglass, etc., with cathodic protection (e.g.,
				impressed current or sacrificial anodes); and
iii) Electrical isolation devices, such as
				insulating joints, flanges, etc.
BOARD NOTE: The practices described in the National
				  Association of Corrosion Engineers (NACE) standard, "Control of External
				  Corrosion on Metallic Buried, Partially Buried, or Submerged Liquid Storage
				  Systems", NACE Recommended Practice RP0285, and "Cathodic Protection of
				  Underground Petroleum Storage Tanks and Piping Systems", API Recommended
				  Practice 1632, each incorporated by reference in 35 Ill. Adm. Code
				  720.111(a),
				  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 the following:
A)
				That tank foundations will maintain the load of a full tank;
B) That 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
				724.118(a);
				and
C) That tank systems will
				withstand the effects of frost heave.
