3 <br />4. Class __ wells with tubing cemented is the hole; <br />initially and every one (1) or two (2) years thereafter <br />depending on well specific conditions (See Region VIII <br />UIC Sect_cn Guidance #36); <br />5. Class II wells which have been temporarily abandoned <br />(TAd) must be pressure tested after being shut-in for <br />two years: and <br />6. Class III uranium extraction wells; initially. <br />T ~~' VC11TA <br />To assure that the teat pressure will detect significant <br />leaks sad that the casing is subjected to pressure similar. <br />to that which would be applied if tha tubing or packer <br />Pails, the tubing/casing annulus should be tested at a <br />pressure equal to the m^~++*~*** allowed injection pressure ar <br />1000 paig whichever is less. The annular test.preeaurn <br />mast, however, have a difference of at least 200 paig eitlssr <br />greater or less than tha injection tubing pressure.

The duraticn of the pressure test is 30 minutes. <br />2. Both the annul::s and tubing pressures should be <br />monitored and recorded every five (51 manures. <br />3. IL there is a pressure change of '_0 percent or more <br />from the initial teat pressure during the 30 minute <br />duration, the well haB failed to demonstrate mechanical <br />iategity and should be shut-in until it is repaired or <br />plugged. <br />4. A pressure change of 10 percent or more i9 considered <br />significant. If there is no significant pressure <br />change is 30 minutes from the time that the pressure <br />source is disconnected frpm the annulus, the test may <br />be c~leced as passed <br />
