The protective coating in the passage tube is good condition with minor abrasions, mildew throughout and staining along the length from both bird excrement and from the rusting and corrosion occurring on the structures at the upper portions.
In summary the dry interior coatings are in good condition but require some minor preventative maintenance. This area of the tank was recently over coated with the exception of the upper area in the access tube (this area is showing dirt & mildew buildup from condensation). The exterior of the ductile iron inlet pipe is showing 20% coating delamination. This is mainly coated for aesthetics as the bituminous primer is adequately protecting the substrate.
RECOMMENDATIONS
• The dry interior should receive a power wash and power tool cleaning as necessary, and then receive a spot coat in the applicable areas. Primarily the upper portion of the dry passage tube.
• The inlet pipe is recommended to be spot prepped (SSPC-SP2 & SP3) and touched up with epoxy paint.

It is recommended that corrective action is taken in regards to the Exterior and Interior surfaces with proposed Protective Coating Systems. The identified Structural, Sanitary, Safety, & Security deficiencies should be corrected and brought up to code as well.
Additionally, an Annual Washout & Visual Inspection Program should be considered, separately, or as part of an Annual Maintenance Program for comprehensive Tank Maintenance.
RECOMMENDATIONS
• Immediate touch up of all affected areas. The exterior should receive a power wash and power tool cleaning, and then receive a spot prime an intermediated coat and full finish coat in the next 2 to 3 years.
• The interior should receive a SSPC-SP10 “Near White” blast cleaning, and then receive two coats of an NSF approved epoxy coating in the next 2 to 4 years.
• Continue to perform a washout inspection every two years to inspect interior surface areas and remove sediment accumulation.
• Adjust and reseal CP plates.
• Repair foundation grout and caulk.
• Access tube repair. Floating type (not permanently affixed to the roof). Need to cut collar off that is welded to the roof & install a stiffener/doubler plate (1/4in thick x 8 in wide ring), solid weld doubler plate to access tube exterior.

EXTERIOR COATING
The exterior surfaces are coated with an Acrylic Polyurethane coating system. The exterior coatings average 10 – 11 mils dry film thickness. The primer, intermediate and finish coat adhesion is good.
RISER, COLUMNS AND STRUCTURAL MEMBERS
The protective coating on the riser, columns and structural members is good condition. Spot failures due to failed coatings with minor oxidation and corrosion on the all surfaces.
BOWL, BALCONY, SIDEWALLS AND KNUCKLE
The protective coating on the bowl is in good condition. The protective coating on the balcony is in good condition but has several areas of oxidation and corrosion along the floor plates where water has failed to drain and on the handrail top rail and uprights, also along the underside of the balcony floor plates. Sidewall coating is in good condition with the color and gloss retained. The protective coating on the knuckle is in good condition.
DOME
The protective coating on the dome is in good condition. There are areas of minor spot oxidation and corrosion on some of the dome plates and weld seams primarily around the additional apparatus welded in place and at the CP plates.
In summary the exterior protective coating is providing a protective barrier; however it has begun to show wear due to age, environmental exposure and lack of preventative maintenance. Now is the time to conduct spot touch up operations of all affected areas and prepared overcoat the tank to protect the structure and salvage the existing coatings. This will extend the life cycle of the existing coating out another seven to eight years with the goal of not having to blast the exterior back to bare metal.
RECOMMENDATIONS
• Immediate touch up of all affected areas. The exterior should receive a power wash and power tool cleaning, and then receive a spot prime an intermediated coat and full finish coat in the next 2 to 3 years.
