A removable containment apparatus for containing pipeline valve seepage comprising a one piece foldable leak proof membrane with an outer edge contoured to form a container about a pipeline valve when said membrane is folded about a midline and over the pipeline valve, said one piece membrane having: a first section on said edge on said membrane which forms an aperture for an in-line to said valve when said membrane is folded, a second section on said edge on said membrane which forms an aperture for an outline from said valve when said membrane is folded, a third section and fourth section on said edge on said membrane which join and form an aperture for a stem on said valve when said membrane is folded, a fifth section and sixth section on said edge of said membrane which join forming a seam between said in-line and said stem, a seventh section and eighth section on said edge of said membrane which join forming a seam between said outline and said stem, means for removably sealing said first section to said in-line, said second section to said outline, said third section and said fourth section to said valve stem, said fifth section and said sixth section to one another, and said seventh section and said eighth section to one another.
