Inspection Report For

An STI SP001 inspection was completed on Tank #1 in the ACME Chemicals facility located at Harrington, DE on 10/17/2011. The inspection was conducted in accordance with client criterion for NDE which included visual and UT examinations. The tank was built to UL-142 specification for underground storage tanks for storing fuel oil. This tank is presently being utilized for fuel oil as an aboveground storage tank. The inspection was conducted in accordance with requirements of the Steel Tank Institute SP001 Standard. The following is a detailed report of the inspection including findings and recommendations.

1.0 EXECUTIVE SUMMARY

An STI SP001 inspection of Fuel Oil Storage Tank #1 located at the ACME Chemicals site in Harrington, DE was conducted on 10/17/2011. This inspection was conducted to collect data in order to evaluate the mechanical integrity and fitness for continued service of the tank.

The tank is located in an area that does not have secondary containment; however, the secondary containment is scheduled to be installed in the near future. Based on the assumption that the secondary containment will be installedwith in the next year, the tank was evaluated as a Category 1 tank. The tank should be in satisfactory condition after the completion of the recommended repairs for a 20 year inspection interval for Category 1 tanks in accordance withthe STI SP001 Table 5.5.

The tank does not have an emergency relief vent, high level alarm, or high level pump cutoff installed. Recommend these items be installed as soon as possible to comply with the Delaware State Regulations (DNREC Section 3.9, 8, & 11).The supports for this tank do not meet the UL-142 design criteria. Calculations in accordance with the Zick formula results in the tank being stressed at the horn of the saddle (see section 3.2 and 4.2 for more details and recommendations andthe horizontal tank calculations in Appendix A).

The tank heads have a nominal thickness of 0.300" which is below the recommended thickness (of 0.313") in UL-142 for un-braced heads for horizontal tanks larger than 72". The tank heads should be braced in accordance with the UL-142 standard as prescribed in Chapter 13.3 (reference Figure 13.1 and Table 13.2 of UL-142) Please refer to the results and recommendation sections of this report for more detailed information of these and other discrepancies and recommendations that were identified during the course of this inspection.

Next Inspection per SP001 for Category 1 Storage Tanks after recommended repairs are completed: 10/17/2031

3.1 Foundation:

3.1.1 The foundation is constructed of three concrete saddles. There is nocontainment area presently installed. A new containment area is schedule to be install within the next year.

3.1.2 The saddle contact with the shell is at 70" width (cord length to theshell cylinder) on a 10ft diameter vessel. This results in a 71º contact angle. Normal minimum contact angles are recommended to be not less than 120º. This condition may be creating undue stress at the horn of the saddle and should be further evaluated by a mechanical engineer experience in storage tank design. (reference UL-142 Table 31.1 and Appendix G for pages from the PV Handbook by Eugene F. Megyesy (pg 84-85) and ASME VIII, Div. 1 App. G (G6) for supporting documentation).

3.2 Shell:

3.2.1 The shell butt welds seams and head lap welds appear to be insatisfactory condition with no preferential corrosion.

3.2.2 External surfaces have complete coating failure and surface oxidation.

3.2.3 The tank heads have a nominal thickness of 0.300" which is below the recommended thickness (of 0.313") in UL-142 for un-braced heads forhorizontal tanks larger than 72".

3.2.3 The supports for this tank do not meet the UL-142 design criteria.Calculations in accordance with the Zick formula results in the tank beingstressed at the horn of the saddle (see attached calculations in Appendix A). Specifications that do not meet UL-142 criteria are as follows:

A. Foundation contact angle is below 120º (ref. Fig 31.1).

B. The distance from the head to the foundation is greater than D/4 (120"/4 = 30") (ref. para. 31.2.5).

C. There are no wear plates installed on the vessel (ref. para 31.2.6 & Table 31.1).

3.3 Appurtenances:

3.3.1 The shell nozzles are in satisfactory mechanical condition.

3.3.2 External surfaces have complete coating failure and surface oxidation.

3.3.3 The 2" normal vent appears to be in satisfactory condition.

3.3.4 There is no emergency vent installed on this tank as required by Delaware State Regulations (DNREC Section 3.9 & 11).

4.1 Foundation:

4.1.1 Install the containment area as planned within the next year.

4.1.2 The contact angle created by the concrete saddle (less than 120º)may be creating undue stress at the horn of the saddle and should be further evaluated buy a mechanical engineer experience in horizontal storage tank design or built up to 120º minimum contact angle (where the saddle width in contact with the tank (or cord length) is 104"). (reference UL-142 Table 31.1 and Appendix G of this report for pages from the PV Handbook by Eugene F. Megyesy (pg 84-85) and ASME VIII, Div. 1 App. G (G6) for supporting documentation) (reference Appendix H for CAD Drawings of required Mods).

4.2 Shell:

4.2.1 4.2.1 Clean and coat the tank to restore 100% coverage.

4.2.2 Brace the tank heads in accordance with the UL-142 standard asprescribed in Chapter 13.3 (Figure 13.1 and Table 13.2).

4.2.3 Install support wear plates on shell in accordance with therequirements of UL-142 para 31.2.6 & Table 31.1.

4.2.4 Install stiffening rings on shell at the tank supports (reference Zickpaper for design specifications) to relieve stress at the horn of the saddle.

4.3 Nozzle:

4.3.1 Clean and coat the tank nozzles to restore 100% coverage.

4.3.2 Install an 8" Emergency Vent on this tank in accordance with theMorrison Vent Guide (reference Appendix G) to meet the requirements ofthe Delaware State Regulations (DNREC Section 3.9 & 11).

1) Stress Value (S) was determined from API-653 for unknown carbon steel materials.2) Tank contact angle is at 71º. Tank was assessed for 120º contact angle (lowest setting in program) at the nominal thickness of 0.300 inches.3) Stress at the horn of the saddle exceeds the allowable stress for this tank assuming a 120º contact angle (and therefore would be even more stressed at71º).

• At 14.7 psis and 60° F (101.4 kPa and 16° C)

• Interpolate for intermediate values.

• These values taken from NFPA 30.

• These pipe sizes apply only to open vent pipes to the specified diameter not more than12 inches (0.3m) long and a pressure in tank of not more than 2.5 psig (17.1 kPa).

• If tank is to be equipped with a venting device or flame arrestor, the vent opening is toaccommodate the venting device or flame arrestor in accordance with the listed CFH.

NORMAL VENTING RECOMMENDATIONS

Emergency Vents

244

Emergency VentEmergency vent (pressure reliefonly) used on abovegroundstorage tanks, as a code require-ment that helps prevent the tanksfrom becoming over-pressurizedand rupturing if exposed to fire.UL listed.

DescriptionThe 244 emergency vent consists of a body and cover thatmoves up and down on a center pin. Pressure inside thetank forces the cover to lift up off the vent seat, allowingair to exhaust. The center pin guides the movement. Whenpressure falls the cover lowers back down onto seat andthe vent is automatically reset.

Code ComplianceWhen properly sized for the tank, this vent will conform tothe requirements of NFPA 30, 30A, UL 142, UL 2244, API2000, and PEI RP200.

The 244 emergency vent must be properly sized andselected for each specific tank application in order to

meet the proper “venting capacity” requirements.

WARNING!The 244 emergency vent is for “emergency pressure

relief only” and must be used in conjunction witha “normal vent” or pressure vacuum vent such

as a Morrison Fig. 354, 548, 748, or 749.

WARNING!

Material and Configuration Options1. Aluminum Body or Iron Body…suffix (I) indicates iron.

2. Metal-to-Metal Seat (brass) or Soft Seat (Viton®)…suffix(O) indicates o-ring.

3. Male Threads/Female Threads/Flanged MountingConnection…suffix (M) indicates male, and suffix (F)indicates flanged.

4. Opening Pressure Setting…settings indicated areapproximate.

Emergency vent should be set higher than thenormal vent so the normal vent operates first.
