are no breaks, holes, cracks in the discharge pipes! culverts that would result in significant
water leakage. The pipe shape is still essentially circular. All joints appear to be closed and the
soil tight. Corrugated metal pipes, if present, are in good condition with 100% of the original
coating still in placc (cithcr asphalt or galvanizing) or havc becn rclined with appropriatc matcrial
which is still in good condition. Condition of pipes has been verified using television camera

There are a small number of corrosion pinholes or cracks that could leak water and need to be
repaired, but the entire length of pipe is still structurally sound and is not in danger of collapsing.
Pipe shape may be ovalizcd in some locations but does not appear to be approaching a curvature

joints should be repaired prior to the next inspection. Corrugated metal pipes, if present, may be
showing corrosion and pinholes but there are no areas with total section loss. Condition of pipes

Culvert has deterioration and/or has significant leakage; it is in danger of collapsing or as already
begun to collapse. Corrugated metal pipes have suffered 100% section loss in the invert.
HOWEVER: Even if pipes appear to be in good condition, as judged by an external visual
inspection, an Unacceptable Rating will be assigned if the condition of pipes has not been verified
using television camera video taping or visual inspection methods within the past five years, and
reports for all pipes are not available for review by the inspector,

The decision on whether or not USACE inspectors should enter a pipe to perform a detailed inspection must be made at the USACE District level. This decision should be made in conjunction with the
District Safety Office, as pipes may be considered confined spaces. This decision should consider the age of the pipe, the diameter of the pipe, the apparent condition of the pipe, and the length of the pipe.
If a pipe is entered for the purposes of inspection, the inspector should record observations with a video camera in order that the condition of the entire pipe, including all joints, can later be assessed.
Additionally, the video record provides a baseline to which future inspections can be compared. .
