C. Survey by Utility. Each utility shall make a sufficient number of pressure measurements in order to determine if pressures throughout the system are in compliance with the requirements of Regulation .02 of this chapter.
D. Survey Records. Pressure records obtained under §C of this regulation shall be retained by the utility for at least 2 years and shall be available for inspection by the Commission's representatives at all times. Notation of each pressure record shall indicate the following:
(1) The location where the pressure was taken; and
(2) The time and date of the test.
