Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 725 - INTERIM STATUS STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES › Subpart J - TANK SYSTEMS › Section 725.292 - Design and Installation of New Tank Systems or Components

Current through Register Vol. 48, No. 28, July 12, 2024
a) An owner or operator of a new tank system
				or component must ensure 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 so that it will not
				collapse, rupture, or fail. The owner or operator must obtain a written
				assessment reviewed and certified by a qualified Professional Engineer, in
				accordance with 35 Ill. Adm. Code
				702.126(d),
				attesting that the system has sufficient structural integrity and is acceptable
				for the storing and treating of hazardous waste. This assessment must include
				the following information:
1) Design
				standards according to which the tanks and ancillary equipment is or will be
				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 is or 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 sulfides level;
iv) Soil resistivity;
v) Structure to soil potential;
vi) Influence of nearby underground metal
				structures (e.g., piping);
vii)
				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, or fiberglass-reinforced
				plastic;
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 and 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 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)
				Tank foundations will maintain the load of a full tank;
B) Tank systems will be anchored to prevent
				flotation or dislodgement where the tank system is placed in a saturated zone,
				or is located within a seismic fault zone; and
C) Tank systems will withstand the effects of
				frost heave.
