Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part V - Hazardous Wastes and Hazardous Materials › Subpart 1 - Department of Environmental Quality-Hazardous Waste › Chapter 19 - Tanks › Section V-1905 - Design and Installation of New Tank Systems or Components

Current through Register Vol. 50, No. 6, June 20, 2024
A. Owners or operators of new tank systems or
				  components must obtain and submit to the Office of Environmental Services, at
				  the time of submittal of Part II information, a written assessment, reviewed
				  and certified by an independent, qualified professional engineer, in accordance
				  with LAC 33:V.513, 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
				  waste(s) 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
				  administrative authority to review and approve or disapprove the acceptability
				  of the tank system design, must 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:
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. existence of stray electric
				  current;
viii. 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:
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.;
4. for
				  underground tank systems 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 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 LAC 33:V.1503.A.3; and
c. tank systems will withstand the effects of
				  frost heave.
