				completion of the repairs and before the UST is placed back in operation,
				repairs to secondary containment areas of tanks and piping used for
				interstitial monitoring and to containment sumps used for interstitial
				monitoring of piping must have the secondary containment tested for tightness
				in accordance with the manufacturer's instructions or a nationally recognized
				code of practice; all other repairs to tanks and piping must be tested for
				tightness as required under
				18 AAC 78.065(d)
				and 18 AAC 78.070(c)
				not later than 30 days after the date of completion of the repairs and before
