Blasting operations. 3.9.1 Blasting within 500 feet of the pipeline right-of-way:
Blasting operations. For any blasting operation within one-fourth mile of a pipeline, the pipeline operator should be supplied with a pre-work survey, including a written report documenting any special conditions or proposed adjustments which are to be incorporated into the seismic testing or blasting activity plan to prevent possible damage to pipeline systems. This survey should be performed by an accredited third-party surveyor and reviewed by appropriately qualified personnel of the pipeline operator. A seismic monitoring unit should be inserted directly over the pipeline and covered with sandbags if soil conditions prevent adequate insertion. The Peak Particle Velocity (PPV) should not exceed two (2) inches per second (IPS) for any blast. The pipeline operator should be notified of any PPV readings approaching or exceeding 2 IPS.
Blasting operations. Any damage arising from blasting operations or related excavation work or an explosion in an explosives xxxx house shall not be indemnified.
Blasting operations. Prior to commencement of any blasting activity within one-fourth mile of Company’s facilities or pipelines, permission must be received in writing from Company. For any blasting operation within one-fourth mile of Company’s facilities or pipelines, Company shall be supplied with a pre-work survey, complete with a written report documenting any special conditions or proposed adjustments which shall be incorporated into the seismic testing or blasting activity plan to prevent possible damage to facilities or pipeline. This survey shall be performed by an accredited third party surveyor and will be reviewed by Company. The third party responsible for the blasting shall notify Company immediately if any changes are made to the blasting plan. If blasting is to be performed within 600 feet of the pipeline, a seismic monitoring program shall be instituted by the contractor. A seismic monitoring unit in good working condition shall be utilized to measure the vibration at the pipeline. The geophone shall be inserted directly over the pipeline and covered with a sandbag if soil conditions prevent adequate insertion. The Peak Particle Velocity (PPV) shall not exceed two inches per second (IPS) for any blast. Company shall be notified of any PPV readings approaching or exceeding 2 IPS. No blasting shall be conducted closer than 50 feet to Company’s pipeline sunless specifically approved by Company. Anyone suspecting blasting damage shall notify Company. If Company has reasonable cause to believe that damage could have occurred during blasting operations, then Company may recommend the pipe be proof tested and/or excavated and inspected. If PPV from blasting operations exceeds 2 IPS, then a proof test (leak survey) will be conducted by Company. A Company representative shall be on site at the location of the blasting activity to observe the right of way during the proof test.
