5/13/21:
1. At approximately 1415, located the release of a spill by driving by the area and smelling fuel
odor coming from the 2D LAAD compound at B4213.
2. Upon inspection of compound, found five 20 gal over packs sitting empty on top of the drains
near OWS‐12. The over packs had contained fuel and the odor of fuel was heavy in the area.
There was fuel/oil seen in the grit chamber, the drain, and OWS‐12.
3. Upon speaking with the Marines, it was determined that “bad” fuel from a tactical MTVR was
drained due to water in the fuel and was improperly disposed of down the drain. They thought
they were dumping it into OWS‐12 which is still an improper disposal method. They were
provided proper guidance on the correct disposal methods for bulk fuel.
4. Upon further investigation of the site, standing fuel was found in the grassy area outside the
fence near AST 4213‐2. The source was undetermined at first and appeared unrelated to the
fuel being dumped down the drain. Absorbents and a vac truck were used to remove the
standing fuel which was initially estimated to be 100 gals.
5. At 1424, reported spill to Station Fire Dept.
6. While removing the standing fuel, fuel was noticed bubbling up out of the ground along the
fence line. This was first believed to be from the heating oil tank as the underground fuel supply
line runs near that location. However, the fuel was dyed red. It was determined that the boiler
was already secured for the season and the fuel supply lines were secured as a precaution.
7. At around 1445, an emergency utility locate was called in so excavation of the contaminated soil
could being. The utility locator did not arrive on scene until 1600.
8. After removing all standing fuel, the grit chamber, the drain, and OWS‐12 were cleaned of all
fuel/oil. It was at this time that it was noted that the storm water overflow pipe at the grit
chamber was capped to the storm water drain. This drain is where the fuel was directly dumped.
Upon further observation, a repair in the asphalt that lead from this storm water drain to the
area where the fuel was bubbling up was noticed. Near the fence, the block of concrete was
determined to be a small stem wall that a PVC drain pipe coming from the drain was located and
had been buried under soil. Upon uncovering it and the end of the pipe, it was determined to be
the source of the fuel in the grassy area.
9. The site was secured around 1700.
5/14/2021
1. At 0800, excavation of the site began.
2. At 0815, the storm drain was cleaned of all sludge and the drain line was flushed with water and
captured with a vac truck. The vac truck was kept on site until 1130 to remove any standing
water or fuel that accumulated in the excavation site.
3. The excavation removed 25‐30 cubic yards of soil.
4. In all areas, the bottom screenings using a PID below 1.2 ppm for TVOC. Due to depth of the
excavation, the only area where a side wall reading was taken was in the area below the end of
pipe where a depth of 38 inches was reached. The side wall sample under the pipe was 55 ppm.
This was in a layer of subgrade gravel below a layer of geotechnical fabric.
5. At 1400, due to constraints from utilities, no further excavation was able to be completed by
PWD. The site will be turned over to the Installation Restoration Program for further evaluation
and cleanup.
6. The contaminated soil and absorbent materials will be disposed of via DLA.
7. The recovered fuel/oil will be incorporated into the used oil recycling program.
8. At 1530, the area was backfilled and seeded.
9. At 1625, verbal notification of the release was provided to Chris Pullinger.
10. The spill report provided by the unit notes the release to be no greater than 80 gals of JP5 as
that is the fuel capacity of the MTVR.
