Description
AECS was contracted by a private client to respond to an emergency situation at one of its former
stations where site investigation activities were being conducted, and the
investigation contractor had hit and ruptured an active underground fuel product
line. Upon arrival at the site,
AECS verified that the fuel flow through the ruptured line had been stopped and
erected barriers around the damaged site. The
covering concrete was saw cut and removed and the soil excavated to expose the
damaged pipe. A minimal hole was
excavated in order to determine the extent of the damage and resulting fuel
contamination. The free product and
liquid contamination was removed from the site using a vac truck, and the
contaminated soil was excavated and stored in drums for eventual transportation
and disposal as petroleum-contaminated soil at an authorized facility.
As the excavation was not large enough for a line splice, an attempt was
made to patch the hole, however the patch did not hold under a line tightness
test, and the excavation was enlarged slightly to allow for removal of the
damaged section of pipe and application of an approved splice.
Due to extremely adverse weather conditions, a non-sparking heater was
used throughout the night to keep the splice heated to an adequate temperature
for the splice adhesive to cure properly. The
repaired line was given a line tightness test, which it passed; the excavation
was backfilled with pea gravel; and the excavation site was resurfaced with
concrete.
