**body:**

The assessment interval defined in 49 CFR 195.452 (j)(3) will be exceeded due to multiple incomplete tool runs. A geometry tool was run on 03/07/17 and 06/25/19. Both geometry runs were successful and resulted in 100% sensor coverage. A MFL tool was run on 03/09/17 resulting in 62% sensor coverage. An additional MFL tool was run on 06/26/19 and became stationary in the pipeline. See "Basis" section below for full timeline of attempted assessments.
