Good Practices

		1.	A question has come up in our stations about how
often to perform
		leak checks on DRDs. The manufacturer says they should be
done monthly, but
		industry practice is every 6 months or every year, after the
initial leak
		check. Does anyone know the basis of the manufacturer's
recommendation for
		monthly checks, or the basis for less frequent checks.
		2.	Does anyone have references/information on good
programs for
		managing DRDs?

		Thanks in advance
