An inspection authority shall evaluate the compliance of the technological equipment of a station with the requirements of these Regulations on the basis of the results of a full, partial or extraordinary inspection and a professional judgement. The inspections shall be performed on the basis of an invitation of the possessor of the station. The procedures for the performance of an inspection and the payment shall be determined in an agreement between the possessor of the station and the inspection authority. The State supervisory and control authorities, within the competence thereof, shall perform the supervision of the technological equipment of stations. 69.

Tanks and pipes have passed a hydraulic test if no pressure drop has been detected during the test. A pipe has passed the pneumatic test if no leakage has been detected during the test, in performing the test throughout the length of the pipe with a leak indicator solution. 86. A hydraulic test of double-walled pipes before the end of service life (resource) shall not be required, unless depressurisation of a pipe has been determined. 87. Station tanks and metal pipes, the manufacturer-specified service life (resource) of which has expired, may be further utilised if an inspection authority evaluates them as adequate in order to bear the loads intended for them. In future, a hydraulic test of such tanks and pipes shall be performed not less than once in three years. 88. Non-metal pipes, the manufacturer-specified service life (resource) of which has expired, shall be recognised as unfit for use. 89. If a tank or a pipe has depressurised, the technological equipment of a station shall be recognised as unfit for use. Further utilisation of the technological equipment of the station is allowable if the damaged installations are fenced off and do not affect the operation of the station, which an inspection authority shall confirm after an extraordinary inspection.
