The tubing/casing <br /> annulus pressure and injection' pressures must be <br /> monitored continuously and the average, maximum, and <br /> li minimum monthly results zre included in the <br /> quarterly report to the director. <br /> (b) Schedule: for, Demonstrations .of Meehan cAl =Integrity <br /> (i) A demor�strat1lon of a mechani a �inegrt,f shall <br /> be made ',notl ess} frequetly than everyyear from <br /> the e�f Mpg-2 � _ of1�he � In <br /> accrd�anewith40 GFR1468. arid aragraph (a) <br /> (. <br /> rr3��- •'::F= C ab- `Nlechani a integrity shall also be <br /> �r .. demonstrated any time that a workover is <br /> conducted, the construction of the well is <br /> modified or when loss of mechanical integrity <br /> becomes evident during operation. <br /> )Y/ (ii) It shall be the permittee's responsibility to <br /> arrange and conduct the mechanical integrity <br /> demonstrations.
