Universal Citation: LA Admin Code XI-705

Current through Register Vol. 50, No. 9, September 20, 2024

A. All UST system owners and operators shall maintain records in accordance with LAC 33:XI.509 demonstrating compliance with all applicable requirements of LAC 33:XI.701-703 and LAC 33:XI.803.D. These records shall include the following.

1. All written performance claims pertaining to any release detection system used and documentation of the manner in which these claims have been justified or tested by the equipment manufacturer, installer, or thirdparty independent testing laboratory must be maintained throughout the operational life of the release detection system. Beginning no later than September 20, 2021, records of the site assessments required under LAC 33:XI.701.A.5.b.vi and LAC 33:XI.701.A.5.c.v shall be maintained as long as the methods are used. Records of site assessments developed after September 20, 2018, shall be signed by a professional engineer or professional geologist, or equivalent licensed professional with experience in environmental engineering, hydrogeology, or other relevant technical discipline acceptable to the department.
a. The department may waive the site assessment requirement for UST systems that were conducting vapor or groundwater monitoring prior to September 20, 2018, if the applicable requirements of LAC 33:XI.701.A.5.a, b, and c were verified during a compliance evaluation inspection. In these cases, the department will provide a written waiver to the facility that shall be maintained for as long as the methods are used.

2. The results of any sampling, testing, or monitoring shall be maintained for at least three years, except that the results of tank tightness testing conducted in accordance with LAC 33:XI.701.A.3 when used in combination with inventory control and manual tank gauging as a release detection method shall be retained until the next test is conducted, and shall contain, at a minimum, the following information.

Tank tightness test reports shall include the date of the test, the tank identifier, a qualitative result statement, a calculated leak rate, and any other information needed to verify compliance with LAC 33:XI.703.A.2.c as applicable to the equipment and method used. Raw data generated for each tank tightness test shall be provided to the department upon request.

d. Automatic Tank Gauging (ATG)
i. AT G test reports shall include:
(a). the time, date, or period covered for the test;

e. Vapor Monitoring with RDD
i. Vapor monitoring RDD records shall include:
(a). the date the analysis was conducted;

(b). the well identifiers;

(c). the concentration measured in each well in parts per million;

(d). a statement or signifier if any of the measured concentrations represents a suspected release (any significant increase in concentration above background); and
