Region VIII's procedure for running a pressure test is <br />intended to aid UIC field inspectors who witness pressure tests <br />far the purpose of demonstrating that a well has Part _T of <br />Mechanical Integrity. The guidance is also intended as a means <br />of informing operators of the procedures required for conducting <br />the test is the absence of as EPA inspector. <br />Pregeure Teat neecr'ntion <br />Te9L ='"~!nien~ <br />The mechanical integrity of as injection well must be <br />maiataiaed at all times. Mechanical integrity pressure <br />teats are required at 1~asL every five (5) years. If for <br />an}r reasaa the tubing/packer is pulled, hDrever, the <br />iajectiaa well is required to pass another mechanical <br />integrity teat prior to rncommeacinq iajectioa regardless o! <br />rhea the last teat wee conducted. The Reaioaal IIIC nroaram <br />mast be not14'ed of the workover and the nronoaed date of <br />the nreeeure teat. The well's teat cycle would they start <br />from the date of the Her test if the wall passes the teat <br />and dncumrntatioa is adequate. Tests may be required oa a <br />more frequent 5asis cepeadin3 oa the nature of the iajectate <br />and the constract_cn of the well (see Section Guidance oa <br />MITs for wells with cemented tubing sad regulations for <br />Claee I wells). <br />Region VIII's criteria for well testing frequency is as <br />follows: <br />1. Class I hazardous waste injection wells; initially (40 <br />CFR 146.o8(d1(1lJ sad annually thereafter: <br />2. Class I nos-hazardous waste injection wells: initially <br />sad every two (zl years thereafter, except for old <br />permits (such as the disposal wells at cazbon dioxide <br />extraction plants which require a test at lea.~L every <br />five years!; <br />3.. Class II wells with tubing, casing and packer; <br />initially and at .east every five (5) years thereafter; <br />
