Archived Rulemaking: Interval for Review and Calculation of Relief Device Capacity

51-fr-21939.pdf (210.54 KB)

This notice proposes to permit calculations made to verify capacity of relieving devices to be performed on the same interval (not to exceed 15 months, but at least once each calendar year) as required if capacity tests are actually performed. The present interval, "one-year," causes inconvenience in scheduling and possibly added inspection costs with no greater safety benefits than the interval proposed here.
