In response to an inquiry from the city, Kinder Morgan representatives said the pipeline was being pressure tested with water, and the forcible removal of water was the cause of the noise.
Kyle officials were notified prior to the test of increased noise production, but a press release issued by the city stated that it was not aware of how loud the process would be.
According to the release, Kinder Morgan went on to inform the city that efforts to dry the pipeline with forced air would continue through Aug. 16 but claimed the noise level should be lessened. Kinder Morgan also has plans to conduct similar testing on the west side of I-35 in the coming weeks.
An official with the city of Kyle said citations can be issued to Kinder Morgan for the duration of the project beginning 24 hours after the issuance of the notice of noncompliance.
The Kyle Police Department will monitor noise levels by taking decibel readings at the property line and may issue citations if violations are observed, the release stated.
Residents affected by excessive noise levels from work on the pipeline may contact the city to file a complaint.
