	In the rare case that there are bottom flange cover plates, it is the responsibility of the SPM or SLE to coordinate with district bridge engineer or review visual records and field inspection notes and decide if these plates need to be tested. This should include only welded cover plate ends that terminate in a tension zone. If cover plates terminate at the inflection point or past it, there is a small chance that the bottom flange cover plate welds would need to be tested. (Rarely, other areas of cover plate welds could be tested based on deteriorated conditions as reported from the field on the Structural Rehabilitation Checklist.)
