3.28 811 Center Data

Practice Statement:

All 811 centers annually submit their ticket and transmission volumes to the OCSI Data Collection Tool.53

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 811 center ticket and/or transmission volume to damages or events that have occurred. Many 811 centers currently provide this data to the OCSI data collection tool. Receiving ticket and transmission volumes from all 811 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.
