				  192.745(d)]
1. Operators must achieve a valve closure
				  time of 30 minutes or less, pursuant to
				  §2736 B,
				  through an initial drill and through periodic validation as required in
				  Paragraph D.2 of this Section. An operator must review and document the results
				  of each phase of the drill response to validate the total response time,

				  192.745(d)(1)]
2. Operators must achieve a valve closure

				  identification. [49 CFR
				  192.745(d)(2)]
3. If the 30-minute-maximum response time
				  cannot be achieved during the drill, the operator must revise response efforts
				  to achieve compliance with
				  §2736 as soon
				  as practicable, but no later than 12 months after the drill. Alternative valve
				  shut-off measures must be in place in accordance with Subsection E of this
				  Section within 7 days of a failed drill. [49 CFR
				  192.745(d)(3)]
4. Based on the results of response-time
				  drills, the operator must include lessons learned in: [49 CFR
				  192.745(d)(4)]
a. training and qualifications programs;
				  [49 CFR
				  192.745(d)(4)(i)]
