It is recommended that underground warning/marking tape be buried at a depth of 12 in (30 cm) or less below grade. The minimum distance from the top of the pipeline should be 12 in (30 cm), with 24 in (60 cm) -36 in (90 cm).
Each run of underground warning/marking tape must be overlapped by a minimum of 20 ft (6 m) or must be joined.
