WO 0213474 T-24A CONDENSATE STORAGE TA-NK INSPECTION PLAIN Materials needed Camera, Numerous sample bags or bottles with DD tags. Pen to mark samples, tape measure. filter sock note pad to document dimensions and other findings.

Take pictures of tank, any debris or corrosion prior to disturbing or collecting sam ples.

Note initial findings in tank.

Inspect bottom of tank for loose debris. Note location of debris (map). Evaluate if debris is stuck in slime layer or loose. Collect and save if possible all loose debris so amount can be quantified. Distinguish and Separate neutrally buoyant from non-buoyant material Inspect bottom of tank for ongoing corrosion/pitting and note locations. Evaluate whether corrosion is loose (Flaking) and can easily be removed. Obtain samples of any corrosion products which can be easily removed.

"Note any film on the bottom of the tank and obtain sample.

Inspect the sides of the tank for corrosion. Determine if corrosion easily flakes off.

Obtain samples of corrosion only if it can be easily removed (no scraping or grinding),

using care to determine and save size of flakes. Note location of the corrosion above or below the suction pipe.

Look for any paint/liner that is chipping. Determine if paint is loose and could be removed. Collect samples of any easily removable loose paint. Remove to keep samples in the size that would flake off. Note location of the loose paint, above or below suction pipe.

'Inspect dovn into the pump suction pipe if possible Note any corrosion or debris in the suction pipe. Collect samples fi'om suction pipe.

Inspect all pipe nozzles, check for coating condition and corrosion. Obtain samples of any loose material.

Take pictures of pump suction line area where it enters the tank. Measure the deflector/anti-Vortex Baffle and any pertinent information to be used to determine the likelihood of drawing debris from the bottom of the tank.

Insure a fresh sock is installed on the drainpipe.

Notify Maintenance to clean/flush the bottom of the tank to the drain.

Evaluate the results of the inspection.
