La. Admin. Code tit. 33 § XI-1303
A. The terms defined in this Section shall have the following meanings in this Chapter.
Closure- the process of removing and disposing of a UST system no longer in service, the process of abandoning such a system in place through the use of prescribed techniques for the purging of vapors and the filling of the vessel with an inert material, the process of properly labeling a tank, and the process of collecting subsurface samples.
Closure-Critical Juncture- those steps in the UST system closure process that are crucial to the prevention or detection of releases from that system. These steps are:
a. the process of cleaning/vapor removal;
b. all subsurface sample collection events, unless a response action contractor approved by the department under LAC 33:XI.Chapter 12 is present and is exercising responsible supervisory control of sample collection events; and
c. the removal or filling with inert material of the tank.
Critical Junctures- those steps identified in installation-critical junctures, repair-critical junctures, or closure-critical junctures of UST systems, as defined in this Section.
Individual Certification- certification in either installation/repair or closure of a UST system.
Install- the process of placing a UST system in the ground and preparing it to be put into service and the process of renovating an existing site (i.e., replacing product piping, adding new product piping, and installing new containment sumps).
Installation-Critical Juncture- those steps during the installation of a UST system that are crucial to the prevention or detection of releases from that system. These steps are:
a. the preparation of the excavation immediately prior to receiving backfill and the tank;
b. the setting of the tank and the piping, including placement of any anchoring devices, backfilling to the level of the tank, and strapping (if any);
c. any time during the installation in which piping components are connected;
d. all pressure testing of the UST system (including associated piping) performed during the installation;
e. completion of the backfill and filling of the excavation;
f. installation of release detection devices within the excavation zone;
g. installation of containment sumps; and
h. installation of spill and overfill prevention equipment.
Person- an individual who engages in the installation, repair or closure, as defined in this Section, of UST systems.
Renewal Fee -biannual fee for installation/repair and/or closure certification.
Repair- modification or correction of a UST system through such means as replacement of valves, fill pipes, vents, and liquid level monitoring systems, and the routine maintenance and inspection of the efficacy of cathodic protection devices.
Repair-Critical Juncture- those steps in the UST system repair or modification process that are crucial to the prevention of releases from that system. These include the following:
a. the completion of the excavation of existing tanks and/or piping;
b. the actual performance of the repairs to the tank and/or piping;
c. any time during the repair process when components of the piping are connected;
d. any time during the repair process when the tank and/or the associated piping are tested; and
e. any time during the modification process when equipment is connected to the tank and/or piping.
UST Certification Board- a board of seven members, to be appointed in the manner prescribed in LAC 33:XI.1313, for the purpose of providing expert counsel to personnel of the department with respect to determining applicant eligibility, and the examination, certification, and certification renewal of persons engaged in UST system installation, repair and/or closure. The board's activities are, however, advisory only, and final authority for administration of the certification program rests with the department.
