3.28 One Call Center Data

One Call Center

Practice Statement:53

All one call centers annually submit their ticket and transmission volumes to the OCSI Data Collection Tool.

Practice Description:

Ticket and transmission volumes from the One Call Systems International (OCSI) data collection tool are shared with the Damage Information Reporting Tool (DIRT) to make a correlation between one call center ticket and/or transmission volume to damages or events that have occurred. Many one call centers currently provide this data to the OCSI data collection tool. Receiving ticket and transmission volumes from all one call centers allows all stakeholders to review, on a national level, more accurate projections and to determine the cause and possible solutions for damages to subsurface installations.
