Incident Number 201700546 - Town of Weldon Sludge Spill
Mr. Rimmer,
Thank you.
On April 17, 2017 at 8:00AM, Bill Hux and Bobby Lyons (back-up ORCs/operators) arrived at
the Town of Weldon WWTP. Upon completing morning rounds, at 8:30AM Bill Hux
noticed/found the above ground sludge storage tank had leaked roughly 6,000 gallons of sludge
on the ground. The gallons were determined based off the volume of the tank in inches and the
number of inches the sludge level dropped inside the tank. The leak was caused by a small
rusty spot that appeared to be surface rust. A wad of rags initially seal the hole. Bill made a
wooden plug and drove it into the hole temporarily until a permanent repair could be made. At
8:53AM Bill called me to advise me of what he had discovered and told me the actions he had
taken. I arrived at the WWTP at 9:10AM. A local industrial cleaning company (MPW) with a
vacuum truck was contacted to assist with the clean-up effort. The sludge was spilled on the
ground between the sludge tank and the sludge drying beds. The sludge was/had stabilized
however bales of hay were placed around the perimeter to prevent any further movement. Upon
being advised that MPW was unable to arrive until Tuesday 4/17/17 the town utilized our
tractor/ffontend loader to scoop the sludge off the ground and place it on the sludge drying beds.
Once the sludge was removed, lime was spread over the affected area. A toggle anchor with
rubber gasket and washers was installed to replace the wooden plug. I contacted you Monday
(4/17/17) at 1:23PM to report this spill.

The operators alternate visiting the WWTP on weekends and Holidays (2 times per day) to
ensure the WWTP is operating properly, the change flow charts and pump scum basins down.
Bill’s last visit to the WWTP on Sunday was at 5:00PM. The leak occurred sometime between
Sunday (4/16/17) night/early Monday morning.
