EXECUTIVE SUMMARY

An API Standard 653 Out-of-Service inspection of Tank #1 (Facility 5042) at Scott ANG Base, IL was completed on January 21, 2016. The bottom service life evaluation shows that the out of service interval of operation (years to next internal inspection) to be greater than 30 years under current conditions. The shell service life evaluation performed as having greater than 30 years of remaining shell life under current conditions. The next internal inspection should be accomplished by a Certified Inspector prior to January 2046 in accordance with the API Standard 653 based on bottom corrosion rates and release prevention barrier under the tank bottom. UFC 3-460-03 currently requires the out-of-service inspection to be every 10 years; therefore, the next out-of-service inspection is due by January 2026. Inspection Results are listed in section 4.0.

4.0 INSPECTION RESULTS

The inspection significant findings (deficiencies) are based on the following definitions:

Urgent (significant findings include: (a) bottom and/or shell thickness below the minimum thickness requirements of API Standard 653; (b) tank leaks or suspected to be leaking to include welds; or, (c) any other identifiable feature that poses an imminent danger to life, limb or property if continued normal service). The tank should not be placed into service for any reason unless emergency operations of the tank are required.

Compliance (significant findings include: (a) API non-conformances; (b) tank service life is less than 10 year inspection intervals; or, (c) Federal, State and/or Local Regulations non-conformances to include NFPA 30, CFR, or OSHA, as a minimum).

The API significant findings are based on the API standards at the time of the original construction, repairs, and/or upgrades. The regulatory regulations are based on current regulations. The tank can be placed back into normal service; however, these significant findings should be scheduled for corrective action as soon as possible.

Upgrade (significant findings include: (a) UFC 3-460-01 requirements; (b) UFC 3- 460-03 requirements; (c) DoD Standards; or, (e) other applicable military standards).

These significant findings are not required to be corrected. The tank can be placed back into normal service until these significant findings are scheduled for corrective action, if warranted.

Prolong (significant findings include any identifiable features to prolong the life of the tank not included in the Upgrade category and/or are of good engineering/ operational practices). These significant findings are not required to be corrected;

however, they will increase the service life of the tank and/or are of good engineering/operational practices.

Rehabilitation (significant findings include identifiable features that were compliant to the API standards at the time of the original construction, repairs, and/or upgrades and do not conform to current standards). These significant findings are not required to be corrected; however, any repairs and upgrades conducted that affect these items may require repair to meet current standards.

The inspection significant findings (deficiencies) requires a corrective action (repair), which are identified as follows:

Level 1 (corrective action requires the tank to be out-of-service).

Level 2 (correction action does NOT require the tank to be out-of-service).

Level 3 (No corrective action suggested).

4.1 Secondary Containment

4.1.1 General Findings: 40 CFR 112.7(c) states that the entire secondary containment system, “including walls and floor, must be capable of containing oil and must be constructed so that any discharge from a primary containment system ... will not escape containment before cleanup occurs.” 40 CFR Sections 112.8(c) (2) and 112.12(c) (2) state that diked areas must be “sufficiently impervious to contain oil.” The purpose of the secondary containment requirement is to prevent discharges as described in 40 CFR 112.1(b); therefore, effective secondary containment methods must be able to contain oil until the oil is cleaned up. The secondary containment area consists of a concrete floor with vertical concrete walls with an HDPE liner underneath. An informal containment evaluation was conducted. Field assessment indicates that the containment is of sufficient size to contain a total tank loss and thus satisfies the requirements of API Standard 653.

The secondary containment area appears to be properly graded to drain water away from the tank in accordance with NFPA 30. The containment drain is in satisfactory condition.

4.1.2 Significant Findings:

1) Prolong: The containment floor has failed expansion joint sealant that has cracked, deteriorated, and lost seal from the concrete, which may prevent containment of product as required by 40 CFR 112. (Quantity: 450 linear feet)

2) Prolong: The interior containment walls have failed expansion joint sealant that has cracked, deteriorated, and lost seal from the concrete, which may prevent containment of product as required by 40 CFR 112. (Quantity: 140 linear feet)

4.2 Foundation

4.2.1 General Findings: The tank rests on top of a concrete ringwall. The tank has secondary containment underneath the bottom with bottom leak detection system. The top of the ringwall was covered by a rain shield and as such, the inspection was limited.

The foundation was evaluated for shell settlement in accordance with API Standard 653 and is in satisfactory condition. The shell settlement calculations are shown in Appendix A.

4.2.2 Significant Findings: No significant findings noted.

4.3 Cathodic Protection

4.3.1 General Findings: No general findings noted.

4.3.2 Significant Findings

1) Upgrade: The tank is not equipped with a cathodic protection system in accordance with UFC 3-460-01 Sections 2-13.1 and 8-8.5, and AW 78-24-27 Drawing D.15. (Quantity: 1)

4.4 Bottom

4.4.1 General Findings: The tank floor consists of 12 plates that are of a lap-welded, cone-down configuration. The bottom was scanned with MFL technology (95%) and no areas of significant underside corrosion were located. Ultrasonic thickness readings were taken on the bottom plates. The bottom has a thin film epoxy coating system. The coating was inspected for disbonding, adhesion, deterioration, and discoloration, which is in satisfactory condition except as noted in the significant findings below. The bottom was scanned (approximately 95%) for underside corrosion using magnetic flux leakage (MFL) technology. The MFE 2412 Mark II unit was used for the MFL floor scan. The MFL scan did not reveal any areas of underside corrosion. The bottom has no significant stockside (top side) pitting. The general thickness of each bottom plate was measured using ultrasonic technology. The general thickness measurements and associated thickness measurement locations (TML) are listed in the Bottom Plate Thickness Measurements table in Appendix C. The bottom is equipped with a circular 30-inch sump having a depth of 15 inches located in the center of the floor. The general thickness of the sump was measured using ultrasonic technology, which is in satisfactory condition. The bottom plate butt-welds, shell-to-bottom weld, attachment welds, piping supports, and support pads were visually examined and appear to be in satisfactory condition, except as noted in Significant Findings below. The visual examination of the welds for defects was extremely limited since the welds are coated. The bottom service life evaluation shows that the out of service interval of operation (years to next internal inspection) to be greater than 30 years under current conditions. The bottom service life evaluation is shown in Appendix A.

4.4.2 Significant Findings

1) Upgrade: The floating roof anti-rotation clip is welded to the floor without a lap-welded reinforcement pad in accordance with AW 78-24-27 Drawing D.8 Detail A3. (Quantity: 1)

2) Upgrade: The VAREC mechanical tape level gauge internal float bracket is welded to the floor without a lap-welded reinforcement pad. (Quantity:

1)

3) Prolong: The sump has coating failure. (Quantity: 2 square feet)

4.5 Shell

4.5.1 General Findings: The shell is constructed of A-36 carbon steel material. The shell is a cylindrical design, butt-welded together, consisting of five courses. The shell (interior and exterior) has a thin film epoxy coating system. The coating was inspected for disbonding, adhesion, deterioration, and discoloration, which is in satisfactory condition except as noted in the significant findings below. The shell was evaluated for remaining metal thickness using ultrasonic technology. The ultrasonic thickness measurements and thickness measurement locations (TML) are listed in the Shell Plate Thickness Measurements table in Appendix C. A shell service life evaluation performed on all shell

SCOTT ANG, IL-TANK #1 (FACILITY 5042)-API653 OOS-JAN2016

1256390724E Underline courses shows that the shell has a remaining life of greater than 30 years under current conditions. The shell service life evaluation is shown in the Shell Service Life Evaluation table in Appendix A. Roundness, plumbness, peaking, and banding of the shell are within the allowable tolerances of API Standard 653. The tank is stable and does not appear to be in danger of overturning or buckling due to high winds or seismic conditions.

4.5.2 Significant Findings

1) Upgrade: The spiral stairway treads are welded directly to the shell and do not have reinforcement pads installed in accordance with AW 78-24-27 Drawing D.10 Detail A1. (Quantity: (56) 14-inch x 5-inch pads)

2) Upgrade: The mechanical tape level gauge supports are welded directly to the shell and do not have support pads in accordance with AW 78-24-27 Drawing D.10 Detail A1. (Quantity: (10) 6-inch circular pads)
