substances spilled into any under-dispenser containment sump shall be immediately removed upon discovery to the maximum extent practicable.
5.Submersible Turbine Pump (STP) Secondary Containment. After December 20, 2008, secondary containment for submersible pumps:
a.is required under the following conditions:
i.in any installation of a new STP at a new facility;
ii.in any installation of an STP (the entire STP, STP housing, and riser pipe) at an existing facility where new piping is added to the UST system to connect the new STP to the existing system;
iii.in any installation of a replacement STP (the entire STP, STP housing, and riser pipe) at an existing facility where the piping that connects the STP to the existing piping is replaced. Replacing the metal flexible connector with a single-walled flexible connector requires the addition of a containment sump. Replacing the metal flexible connector with a double-walled flexible connector does not require the addition of a containment sump as long as the newly-installed STP is secondarily contained, and replacing an existing STP where no piping is replaced does not require the addition of STP secondary containment; and
b.can consist of either a built-in secondary containment system or a STP containment sump. STP containment sumps installed after December 20, 2008, shall have liquid-tight sides and bottoms and be maintained free of storm water and debris. Regulated substances spilled into any STP containment sump shall be immediately removed upon discovery to the maximum extent practicable.
a.Installation. All tanks and piping must be installed in accordance with Subsection A of this Section and in accordance with the manufacturer's instructions.
b.Certification of Installation and Verification of Installer Certification
i.From the date of promulgation of these regulations until January 20, 1992, owners and operators must certify installations as follows. All owners and operators must ensure that one or more of the following methods of certification, testing, or inspection is used to demonstrate compliance with Subparagraph D.6.a of this Section by providing a certification of compliance on the UST registration form (UST-REG-02) in accordance with LAC 33:XI.301:
(a).the installer has been certified by the tank and piping manufacturers; or
(b).the installation has been inspected and certified by a professional engineer with education and experience in UST system installation; or
(c).the installation has been inspected and approved by the department; or
(d).all work listed in the manufacturer's installation checklists has been completed; or
(e).the owner and operator have complied with another method for ensuring compliance with Subparagraph D.6.a of this Section that is determined by the department to be no less protective of human health and the environment.
ii.Beginning January 20, 1992, all owners and operators must ensure that the individual exercising supervisory control over installation critical-junctures (as
defined in LAC 33:XI.1303) of a UST system is certified in accordance with LAC 33:XI.Chapter 13. To demonstrate compliance with Subparagraph D.6.a of this Section, all owners and operators must provide a certification of compliance on the UST Registration of Technical Requirements Form (UST-REG-02) within 60 days of the introduction of any regulated substance. Forms shall be filed with the Office of Environmental Assessment.
c.Notification of Installation. The owner and operator must notify the Office of Environmental Assessment in writing at least 30 days before beginning installation of a UST system by:
i.completing the Installation, Renovation and Upgrade Notification Form (UST-ENF-04);
ii.notifying the appropriate regional office of the Office of Environmental Assessment by mail or fax seven days prior to commencing the installation and before commencing any installation-critical juncture (as defined in LAC 33:XI:1303);
iii.including in the notification a statement of the number of active or abandoned water wells within 50 feet of the UST system and the type of system to be installed; and
iv.including in the notification the methods to be used to comply with LAC 33:XI.Chapter 7.
E.Upgrading Existing UST Systems to New System Standards
1.Not later than December 22, 1998, all existing UST systems must comply with one of the following sets of requirements:
a.new UST system performance standards under Subsection D of this Section; or
b.the upgrading requirements in Paragraphs E.3-6 of this Section.
2.After December 22, 1998, all existing UST systems not meeting the requirements of Paragraph E.1 of this Section must comply with closure requirements under LAC 33:XI.Chapter 9, including applicable requirements for corrective action under LAC 33:XI.715.
3.Tank Upgrading Requirements. Metal tanks must be upgraded in accordance with Subsection A of this Section and meet one of the following requirements.
a.Internal Lining. A tank may be upgraded by internal lining if:
i.the lining is installed in accordance with the requirements of LAC 33:XI.507; and
ii.within 10 years after lining, and every five years thereafter, the lined tank is internally inspected and found to be structurally sound with the lining still performing in accordance with original design specifications.
b.Cathodic Protection. A tank may be upgraded by cathodic protection if the cathodic protection system meets the requirements of Clauses D.1.b.ii, iii, and iv of this Section, and the integrity of the tank is ensured using one of the following methods.
i.The tank is internally inspected and assessed to ensure that the tank is structurally sound and free of corrosion holes before the cathodic protection system is installed.
ii.The tank has been installed for less than 10 years and is monitored monthly for releases in accordance with LAC 33:XI.701.A.4-8.
