2)         Test once each quarter of each calendar year, by methods referenced in Section 218.105(g) of this Part, all pressure relief valves in gaseous service, pipeline valves in gaseous service and compressor seals;

3)         Inaccessible valves may be tested once each calendar year instead of once each quarter of each calendar year;

4)         Observe visually all pump seals weekly;

5)         Test immediately any pump seal from which liquids are observed dripping;

6)         Test any relief valve within 24 hours after it has vented to the atmosphere; and
