If drilling with air or other gaseous material as the drilling medium within two hundred feet of an inhabited structure, a BOP in good working condition of sufficient size and working pressure rating to control normal hydrostatic pressure for the deepest pool to be penetrated has to be installed on the casing through which drilling operations are being performed beneath the rotating air-head or when drilling in urbanized areas, unless the chief finds that a BOP is not needed. Blow- out preventors have to be capable of closing off the annulus between the casing and drill pipe as well as completely closing off the casing when drill pipe is not in the holes. Blow-out preventor systems have to include a device which will permit bleed-off of hydrostatic pressure. Upon request of the chief or his inspectors, the owner, contractor or person or organization in control of the well has to demonstrate that the BOP is in good working condition. In addition, the chief may direct a person to use a BOP in other cases when he deems it necessary.
In urbanized areas, the division inspector or supervisor shall has to have direct notification of the BOP test no less than twenty-four hours in advance. The inspector or division representative may waive witnessing the BOP test.
