Section XI-511 - Periodic Testing of Spill Prevention Equipment and Containment Sumps used for Interstitial Monitoring of Piping and Periodic Inspection of Overfill Prevention Equipment

A. Owners and operators of UST systems with spill and overfill prevention equipment and containment sumps used for interstitial monitoring of piping shall meet the following requirements to ensure the equipment is operating properly and it will prevent releases to the environment.

1. Spill prevention equipment (e.g., a catch basin, spill bucket, or other spill containment device) shall prevent releases to the environment by meeting one of the following requirements.

a. The equipment is double walled and the integrity of both walls is periodically monitored at a frequency no less than the frequency of the walkthrough inspections described in LAC 33:XI.513. Owners and operators shall begin meeting Subparagraph b of this Paragraph and conduct a test within 30 days of discontinuing periodic monitoring of the equipment.

b. The spill prevention equipment is tested at least once every three years to ensure the equipment is liquid tight by using vacuum, pressure, or liquid testing in accordance with one of the following criteria:

i. requirements developed by the manufacturer (owners and operators may use this option only if the manufacturer has developed requirements);

ii. in accordance with LAC 33:XI.501.A; or

iii. requirements developed by the department to be no less protective of human health and the environment than the requirements listed in Clauses i and ii of this Subparagraph.

3. Overfill prevention equipment shall be inspected at least once every three years. At a minimum, the inspection shall ensure that the overfill prevention is set to activate at the correct level specified in LAC 33:XI.303.D.3.a.ii and will activate when regulated substance reached that level. Inspections shall be conducted in accordance with one of the criteria in Paragraph A.1.b.i.iii. of this Section.

B. Owners and operators shall begin meeting the following requirements.

1. For UST systems in use on or before September 20, 2018 the initial spill prevention equipment test, containment sump test, and overfill prevention equipment inspection shall be conducted no later than September 20, 2021.

2. For UST systems brought into use after September 20, 2018, these requirements apply at installation.

C. Owners and operators shall maintain records for spill prevention equipment, containment sumps used for interstitial monitoring of piping, and overfill prevention equipment in accordance with LAC 33:XI.509.B as follows:

1. all records of testing or inspection shall be maintained for three years; and/or

2. for spill prevention equipment and containment sumps used for interstitial monitoring of piping not tested every three years, documentation showing that the prevention equipment is double walled and the integrity of both walls is periodically monitored shall be maintained for as long as the equipment is periodically monitored.

D. Owners and operators shall comply with the following requirements whenever a test of spill prevention equipment or containment sumps used for interstitial monitoring of piping or an inspection of overfill prevention equipment fails.

1. Failed equipment shall be repaired or replaced within 30 days of failing the test or inspection unless an alternative timeframe is granted, in writing, by the department.

2. Repairs to failed equipment shall be conducted in accordance with LAC 33:XI.507.
