(a) A value which will not exceed the operating requirements of § 144.28(f)(3) (i) or (ii) as applicable or

(b) A value for well head pressure calculated by using the following formula:

Pm = (0.733 − 0.433 Sg)d where: Pm = injection pressure at the well head in pounds per square inch Sg = specific gravity of injection fluid (unitless) d = injection depth in feet.
