(3) Meets the performance requirements in section 4 or 5 of this rule, with any performance claims and the manner of determination of the performance claims described in writing by the equipment manufacturer or installer. In addition, methods used after the date shown in the following table corresponding with the specified method, except for methods permanently installed prior to that date, must be capable of detecting the leak rate or quantity specified for that method in the corresponding citation of this rule shown in the table with a probability of detection (Pd) of ninety-five hundredths (0.95) and a probability of false alarm (Pfa) of five-hundredths (0.05):

Method	Citation	Date After Which Pd/Pfa Was Demonstrated
Manual tank gauging	section 4(2) of this rule	December 22, 1990
Tank tightness testing	section 4(3) of this rule	December 22, 1990
Automatic tank gauging	section 4(4) of this rule	December 22, 1990
Automatic line leak detectors	section 5(1) of this rule	September 22, 1991
Line tightness testing	section 5(2) of this rule	December 22, 1990

  (b) When a release detection method that is operated under the performance standards in sections 4 and 5 of this rule indicates a release may have occurred, the owner and operator shall notify the agency under 329 IAC 9-4.

  (c) Owners and operators of all UST systems shall comply with the release detection requirements of this rule by December 22 of the year listed in the following table:

SCHEDULE FOR PHASE-IN OF RELEASE DETECTION
Year System Was Installed	Year When Release Detection Was Required (By December 22 of the Year Indicated)
	1989	1990	1991	1992	1993
Before 1965 or date unknown	RD	P
1965-69		P/RD
1970-74		P	RD
1975-79		P		RD
1980-88		P			RD

New tanks (after December 22, 1988) immediately upon installation. P = Shall have begun release detection for all pressurized piping under sections 2(2)(A) and 3(2)(D) of this rule. RD = Shall have begun release detection for tanks and suction piping under sections 2(1), 2(2)(B), and 3 of this rule.

  (d) Any existing UST system that cannot apply a method of release detection that complies with this rule shall complete the closure procedures under 329 IAC 9-6-2.5 by the date on which release detection is required for that UST system under subsection (c).
