(2) Pressurized piping. For underground piping that conveys regulated substances under pressure, an owner and permittee must insure that the piping is equipped with an automatic line leak detector that alerts an owner and permittee to the presence of a leak by restricting or shutting off the flow of regulated substances through underground piping or by triggering an audible or visual alarm. Interstitial monitoring sensor systems or stand alone "sump" sensors are not an acceptable alternative for a line leak detector. In addition,

(a) The line leak detector must be approved by a national organization (e.g., the National Work Group on Leak Detection);

(b) The line leak detector must be capable of detecting a leak of three gallons per hour at ten pounds per square inch line pressure within one hour; and

(3) In addition to the requirements of section (2) of this rule, an owner and permittee with pressurized piping must conduct an annual line tightness test that can detect a 0.1 gallon per hour leak rate at one and one-half times the operating pressure. Interstitial monitoring sensors may replace the annual line tightness test if:

(a) The equipment is designed, constructed and installed to monitor all portions of the underground piping that routinely contains a regulated substance; and

(b) The requirements for interstitial monitoring (OAR 340-150-0465) are met.

(4) Suction piping. For underground piping that conveys a regulated substance under suction (i.e., piping that operates at less than atmospheric pressure), an owner and permittee must check the piping for the presence of air in the pipeline in accordance with the National Fire Protection Association standard NFPA, 329 "Recommended Practices for Handling Releases of Flammable and Combustible Liquids and Gases" Chapter 5, Release Detection of Tanks and Piping, subsection 5-2.3.2(b), if any of the following indicator conditions are observed by any person dispensing a regulated substance:

(a) If there are indications of air in the pipeline or other unusual operating conditions are observed (refer to National Fire Protection Association standard NFPA, 329 subsection 5-2.3.2(a) for specific indicators), the pipeline check valve should be inspected to determine if it is seated tightly. The check valve must be repaired, replaced or sealed off as appropriate depending on the results of the inspection; and

(b) The requirements of OAR 340-150-0350 through 340-150-0354 must be met for any repair, modification or replacement actions taken to correct a problem.

(5) In addition to the requirements of section (4) of this rule, an owner and permittee of suction piping must conduct a line tightness test at least once every three years in accordance with manufacturers requirements.

(6) Release detection is not required for suction piping that is designed and constructed to meet the following standards:

(a) The below grade underground piping operates at less than atmospheric pressure;

(b) The below grade underground piping is sloped so that the contents of the pipe will drain back into the UST if the suction is released;

(c) Only one check valve is present in each suction line;

(d) The check valve is located directly below and as close as practical to the suction pump; and

(e) A method is provided that allows the department to readily determine compliance with this section of the rule.

(7) In lieu of conducting line tightness tests on either pressurized or suction piping, an owner and permittee may conduct monthly monitoring by one of the applicable release detection methods described in OAR 340-150-0450 through 340-150-0470, if the method is designed to detect a release from any portion of the underground piping that routinely contains a regulated substance.

(8) An owner and permittee must retain at a minimum the last completed line test, line leak detector test or the most current 12 consecutive months of release detection records for piping.

(9) An owner and permittee must report to the department any leak test results or other observations or results indicating the possibility of a release within 24 hours as a suspected release (OAR 340-150-0500) and immediately begin investigation in accordance with 340-150-0510.

Interstitial Monitoring Release Detection Method

(1) An owner and permittee may use an interstitial monitoring system as a release detection method if:

(a) The system is designed, constructed and installed in accordance with a national code of practice or industry standard and the interstitial monitoring system is an approved leak detection system (method and equipment) for that system as listed by a national organization (e.g., the National Work Group on Leak Detection); and

(b) The system is able to detect a leak from any portion of an UST or underground piping that routinely contains a regulated substance.

(2) An owner and permittee must meet the following requirements for the specific type of UST system or piping:

(a) Multiwalled UST systems. The sampling or testing method must be able to detect a release through the inner wall in any portion of the UST. The provisions outlined in the Steel Tank Institute's "Standard for Dual Wall Underground Storage Tanks" (2001) may be used as guidance for aspects of the design and construction of underground metal double walled tanks.

(b) UST systems with a secondary barrier within the excavation zone. The sampling or testing method used must be able to detect a release between the UST system and the secondary barrier.

(A) The secondary barrier around or beneath the UST system must consist of artificially constructed material that is sufficiently thick and impermeable (at least 10-6 cm/sec for the regulated substance stored) to direct a release to the monitoring point and permit its detection;

(B) The secondary barrier must be compatible with the regulated substance stored so that a release from the UST system will not cause a deterioration of the barrier or allow a release to pass through the barrier;

(C) For USTs with corrosion protection, the secondary barrier must be installed so that it does not interfere with the proper operation of the corrosion protection system;

(D) Groundwater, soil moisture or rainfall cannot render the testing or sampling method used inoperative so that a release could go undetected for more than 30 days or one day if used for pressurized underground piping;

(E) Before installation, an owner and permittee must have the site assessed to demonstrate that the secondary barrier is always above the seasonal high groundwater level and not in a 25-year flood plain, unless the barrier and monitoring system are designed for use under such conditions; and

(F) An owner and permittee must mark and secure monitoring wells at all times to prevent unauthorized access and tampering.

(c) USTs with an internally fitted liner. An automated device must be able to detect a release between the inner wall of the UST and the liner and the liner must be compatible with the regulated substance stored.

(d) Double walled pressurized piping. Interstitial monitoring sensors must be installed in any sump which houses a noncontinuous junction of the interstitial space (e.g., any and all points along the piping run where the interstitial space is no longer continuous).

(3) An owner and permittee must monitor the UST and underground suction piping for a release at least every 30 days and record the results for each month.

(4) An owner and permittee must monitor pressurized underground piping for a release daily and record the results daily for each month.

(5) An owner and permittee must retain at a minimum the most current 12 consecutive months of release detection records. Records must include, at a minimum, the date the system was checked, observations made and the name or initials of the person conducting the monitoring. In addition, records for electronic systems must include: power status (on or off), alarm indication status (yes or no) and sensor malfunction noted (yes or no).

(6) An owner and permittee must report to the department any leak test observations, alarms or results indicating the possibility of a release to the interstitial area within 24 hours as a suspected release (OAR 340-150-0500) and immediately begin investigation in accordance with 340-150-0510.

Suspected Release Investigation and Confirmation Steps

(1) Following the discovery of a suspected release of a regulated substance, an owner and permittee must immediately initiate investigation and confirmation of the suspected release as required by this rule. This investigation must be completed within seven days or as otherwise approved or directed by the department.

(2) Upon expiration of the 7-day period or other period approved by the department, an owner and permittee must notify the department of the investigation results by submitting to the department:

(a) A written description of the system test that confirmed a release did not occur, including any test results; or

(b) A written plan of action to complete the suspected release investigation system test or site assessment. Any plan of action must include a firm schedule for completion.

(3) System test.

(a) An owner and permittee must conduct tightness testing to determine whether a leak exists in any portion of the UST that routinely contains a regulated substance (OAR 340-150-0445) or the underground piping (340-150-0410) or both.

(b) An owner and permittee must investigate the cause of a release into any secondary containment unit including, but not limited to, underground piping, turbine sumps, transition sumps and dispenser pans by conducting tests in accordance with manufacturer requirements or as directed by the department. All regulated substances (product) or product and water mixture must be removed from the containment system and properly disposed in accordance with all state, federal and local requirements.

(c) If the suspected release was not reported due to any of the conditions described in OAR 340-150-0500(1)(a) and the system test results do not indicate that a release has occurred, further investigation is not required, unless otherwise directed by the department.

(d) If the suspected release was reported due to any of the conditions described in OAR 340-150-0500(1)(a) or the system test results indicate that a release exists, an owner and permittee must assess and repair, replace or modify the UST system and begin corrective action in accordance with sections (4) and (5) of this rule.

(4) Site assessment.

(a) If the test results for the UST, piping or secondary containment units do not indicate that a release exists, but the suspected release was reported due to any of the conditions described in OAR 340-150-0500(1)(a) or if directed by the department, an owner and permittee must conduct a site assessment for contaminated soil or groundwater. An owner and permittee must measure for the presence of a release where contamination is most likely to be present based on all information available. In selecting sample types, sample locations and measurement methods, an owner and permittee must consider the nature of the stored substance, the type of initial alarm or cause for suspicion, the type of backfill, the depth to groundwater and other factors appropriate for identifying the presence and source of the release. The requirements for sample collection, analytical tests and methods contained in 340-122-0205 through 340-122-0360 must be used as appropriate. The department may require that a sampling plan be submitted for approval before conducting any sampling on a case by case basis. In addition:

(b) If the site assessment results do not indicate that a release has occurred, further investigation is not required unless specifically directed by the department.

(c) If the site assessment results indicate that a release has occurred, an owner and permittee must begin corrective action in accordance with section (5) of this rule.

(5) If the suspected release investigation confirms that a release has occurred, an owner and permittee must report the confirmed release to the department within 24 hours of confirmation and comply with the following release reporting, site investigation and corrective action requirements:

(a) For petroleum USTs; OAR 340-122-0205 through 340-122-0360.

(b) For USTs containing non petroleum regulated substances; OAR 340-122-0010 through 340-122-0115, except that releases must be reported in accordance with the requirements of OAR chapter 340, division 142.
