GENERAL SUMMARY

Summary of Inspection

An API Standard 653 In-Service inspection of Tank 2 (Facility 1841) at JB McGuire-Dix-Lakehurst, NJ was completed on September 15, 2021. The shell service life evaluation performed as having greater than 30 years of remaining shell life under current conditions.

Mandatory None

Short Term

1. The expansion joint sealant is deteriorated on the secondary containment floor, which may prevent containment of product as required by 40 CFR 112. The sealant is dry-rotted, cracked, and many areas have pulled away from the edges of the concrete wall plates. (Quantity: 1200 LF)

2. The containment floor has several areas of exposed cracks, which may prevent containment of product as required by 40 CFR 112. (Quantity: 470 LF)

3. The weld spacing is inadequate between the reinforcement of manhole 1 and the shell-to-bottom weld. The minimum required weld spacing is 3 inches. The weld spacing measured 2 inches.

Magnetic particle (MT) examination is required on the affected welds. (Quantity: 1 area)

4. The weld spacing is inadequate between the reinforcement of manhole 2 and the shell-to-bottom weld. The minimum required weld spacing is 3 inches. The weld spacing measured 1-1/2 inches.

Magnetic particle (MT) examination is required on the affected welds. (Quantity: 1 area)

5. The weld spacing is inadequate between the reinforcement of the 16-inch issue line and the shell-to-bottom weld. The minimum required weld spacing is 3 inches. The weld spacing measured 2 inches.

Magnetic particle (MT) examination is required on the affected welds. (Quantity: 1 area)

6. The weld spacing is inadequate between the reinforcement of the 8-inch receipt line and the shell-to-bottom weld. The minimum required weld spacing is 3 inches. The weld spacing measured 2-1/2 inches. Magnetic particle (MT) examination is required on the affected welds. (Quantity: 1 area)

7. The chime area and sealant condition could not be evaluated due to a tape covering the entire chime area from the shell to the concrete ringwall. The inspection of the chime area is part of the inspection requirements of API Standard 653. The tape covering should be removed for proper evaluation.

Note: The chime extension beyond the shell appears to be sufficient. (Quantity: 200 LF)

8. The product saver tank is not grounded or bonded as required by NFPA 30. (Quantity: 1)

9. The tank does not have an NFPA fire diamond label. (Quantity: 1)

10. The circumferential stairway has inadequate clearance between the handrail and the high level control assemblies. The existing clearance is 18-inches. 29 CFR 1910.25(d)(1) requires a minimum width of 26-inches. (Quantity: affects 8 steps)

11. The bottom step of the stairway at the base of the circumferential stairway has a 19-inch clearance between the first step and the secondary containment floor, which does not meet 29 CFR 1910 step rise and run requirements. The stairway rise measured 9 inches, and the run measured 9-1/2 inches. (Quantity: 1 concrete base)

Long Term

A. GENERAL PROJECT INFORMATION

1. API 653 Inspection This project will perform API 653 inspections of various tanks at facilities throughout the United States. Additional consideration is given to federal, state, and local regulations, as well as applicable military criteria and general industry standards.

An API Standard 653 In-Service inspection was performed for Tank 2 (Facility 1841).

2. Site Information On September 15, 2021, InterSpec, LLC performed an API 653 In-Service inspection of Tank 2 (Facility 1841), located at JB McGuire-Dix-Lakehurst, NJ.

B. TANK INSPECTION COMMENTS

1. Tank Construction Tank 2 is a nominal 25,000 barrel, 63’ 0” diameter by 56’ 3” tall, Jet A, aboveground vertical storage tank. The original construction nameplate was affixed to the tank. The tank had several upgrades/repairs (no nameplates).

2. Secondary Containment 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 112.8(c)(2) and 40 CFR 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 an exposed liner covering earthen material. An informal containment evaluation was conducted. The secondary containment is of sufficient size to contain a total tank loss per UFC 3-460-01 Section 8-14.2.1, “The containment area needs to have sufficient capacity to contain the tank contents plus one foot of freeboard.” The secondary containment area does not drain properly towards the sump.

The secondary containment seams are deteriorating (separation). The secondary containment has minor exposed hairline cracks.

3. Tank Foundation The tank rests on a concrete ringwall. The tank does have an impressed current cathodic protection system. The tank does have a bottom leak detection system with three sumps. The foundation was visually evaluated during the inspection for broken concrete, spalling, cracks, and vegetation against the bottom of the tank. The tank bottom-to-ringwall sealant was not inspected due to a tape covering from the shell to the ringwall. A shell settlement survey was performed during the inspection in accordance with Appendix B of API Standard 653. Settlement results are listed in Appendix A.

4. Tank Bottom The bottom was not evaluated.

5. Tank Shell The shell is constructed of carbon steel material. The shell is a cylindrical design, butt-welded together, consisting of six (6) courses. The shell exterior has a thin film epoxy coating system. The exterior coating was inspected for disbonding, adhesion, deterioration, and discoloration; it is in satisfactory condition. The shell was evaluated for remaining metal thickness utilizing ultrasonic technology. The ultrasonic thickness measurements and thickness measurement locations (TML) are listed in the Shell Plate Thickness Measurements table in Appendix A. A shell service life evaluation performed on all shell courses shows 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, peaking, and banding of the shell appear to be within the allowable tolerances of API Standard 653. The shell plumbness evaluation shows the shell to be within the allowable tolerances of API Standard 653. The shell plumbness evaluation is shown in Appendix A. The tank appears to be stable and does not appear to be in danger of overturning or buckling due to high winds or seismic conditions. The tank does not have any anchoring.

6. Tank Floating Roof The tank is equipped with an internal floating roof. The floating roof is a sealed honeycomb cell floating pan. The roof seals and opening gaskets could not be inspected since the roof circulation vents/inspection hatches could not be opened. The floating roof has a foam dam, and the seals could not be visually inspected from the internal ladder access hatch.

7. Tank Fixed Roof The fixed roof is a self-supported cone roof constructed of carbon steel material. The fixed roof has an epoxy coating system on the exterior. The exterior coating was inspected for disbonding, adhesion, deterioration, and discoloration; it is in satisfactory condition. The fixed roof was evaluated for remaining metal thickness using ultrasonic technology. The ultrasonic thickness measurements and ultrasonic thickness locations (TML) are listed in the Fixed Roof Plate Thickness Measurements table in Appendix C.
