1.) AIR TEST PER THE FOLLOWING:

A.) API650-(7.3.4)

AFTER FABRICATION IS COMPLETED BUT BEFORE THE TANK IS FILLED WITH TEST WATER, THE REINFORCEMENT PLATE SHALL BE TESTED BY APPLYING UP TO 15 PSI (100 kPa) GAUGE PNEUMATIC PRESSURE BETWEEN SHELL & THE REINFORCEMENT PLATE ON EACH OPENING USING THE TELL-TALE HOLE SPECIFIED IN 5.7.5.1. WHILE EACH SPACE IS SUBJECTED TO SUCH PRESSURE, A SOAP FILM, LINSEED OIL, OR ANOTHER MATERIAL SUITABLE FOR THE DETECTION OF LEAKS SHALL BE APPLIED TO

ALL ATTACHMENT WELDING AROUND THE REINFORCEMENT, BOTH INSIDE & OUTSIDE.

GENERAL NOTES:

1. ALL CATHODIC PROTECTION MATERIALS AND COMPONENTS SHALL BE

STORED IN A SHELTERED STORAGE AREA TO PREVENT ANY DAMAGE TO

THEM PRIOR TO INSTALLATION WORK.

2. ADEQUATE SAFETY MEASURES SHALL BE MAINTAINED DURING THE

INSTALLATION OF THE CP SYSTEM.

3. ALL CONSTRUCTION SHALL CONFORM TO NACE STANDARDS AND PROJECT

SPECIFICATIONS, AND SHALL BE AS PER APPROVED DRAWINGS.

4. SUCCESSFUL OPERATION OF THE CP SYSTEM IS DEPENDENT UPON

ELECTRICAL ISOLATION OF THE ANODE GRID FROM THE TANK BOTTOM AND

TANK ISOLATION FROM ANY ADJACENT METALLIC STRUCTURE(S) OR PIPING.

NOTES:

1. ANODE RIBBON LENGTHS ARE IDENTICAL ON BOTH SIDES OF THE TANK CENTER LINE.

2. ANODE AND CONDUCTOR BARS TO BE CUT BACK 6" FROM THE EDGE AT BOTH ENDS.

3. UPON COMPLETION OF THE CATHODIC PROTECTION GRID, ALL PENETRATIONS THROUGH THE TANK WALL SHALL BE SEALED WATER-TIGHT TO PREVENT MOISTURE

MIGRATION BETWEEN THE OLD AND NEW TANK BOTTOMS.

4. ELECTRICAL ISOLATION OF INLET, OUTLET PIPING, TANKS ANCHORS AND GROUNDING SYSTEM IS NECESSARY .

5. RGS COATED CONDUIT NOT TO BE USED UNDER TANK TO PREVENT ELECTRICAL SHORT BETWEEN ANODE GRID AND CONDUIT.

6. CP GRID AND REFERENCE CELLS TO BE INSTALLED ON 1" OF CLEAN SAND BACKFILL.

7. AFTER ANODE GRID IS INSTALLED, A LAYER OF SAFETY NET SHALL BE PLACED ON TOP OF THE GRID TO PREVENT POSSIBLE SHORTING OF THE ANODES TO THE TANK

BOTTOM OR ANY OTHER METALLIC STRUCTURES. SEE DETAIL 8 FOR SAFETY BARRIER.

8. NEGATIVE DRAIN CABLE TO BE ROUTED THROUGH EXISTING CONDUIT TO EXISTING RECTIFIER. STRUCTURE TEST LEAD TO BE ROUTED INTO EXISTING CONDUIT TO

EXISTING JUNCTION BOX

9. COPPER/COPPER SULFATE AND ZINC REFERENCE CELLS TO BE CENTERED BETWEEN ANODE ROWS.

10. CONTRACTOR TO ENSURE THAT CATHODIC PROTECTION COMPONENTS ARE NOT DAMAGED DURING BACKFILLING AND TANK BOTTOM PLATE CONSTRUCTION.

11. USE EXTREME CAUTION TO PREVENT ANY METALLIC CONTACT BETWEEN CP COMPONENTS IN THE SAND BACKFILL AND TANK BOTTOM. SUCH ELECTRICAL SHORT IS

DETRIMENTAL AND SHOULD NOT BE ALLOWED AT ANY TIME.
