shall be made with the info of the tank, or possibly at the lift tug, if steel is exposed, prior to application of the lift lug cover. No current shall pass through the factory installed flange gaskets. Isolation of the fittings is required to assure tank integrity. 8.3 If the tank is to be installed near an Impressed current system, the effect of the system must be considered on the ACT -140® tank. The corrosion consultant must consider including the ACT -100® tank into the design of the impressed current system. 9.0 SEALING of PIPE CONNECTIONS, LIFTING LUGS and REPAIRS 9.1 Clean areas to be repaired through removal of surface rust, dirt, contaminants, and disbonded laminate. The laminate and surface coat surrounding all holidays, laminate flaw areas, lift lugs and/or exposed steel areas shall be surface prepared by using a coarse grit sandpaper or grinder. (Refer to $SPC SP -2 "Hand Tool Cleaning" or SP -3 "Power Tool Cleaning" for additional guidance'. This process shall remove all glossiness from the surface surrounding the repair area. Repair the area by using the repair kit supplied by the manufacturer. 9.2 During the installation process, steel can become exposed at the lift lugs due to handling of the tank or at the interface between tW steel tank and either the nylon bushing or gasket. These areas must be repaired by one of the following methods. 9.2.1 A di -electric cap, if supplied by the manufacturer, shall be placed over each lift lug. First, prepare the surface of the tank to be bonded to the cap in accordance with paragraph 9.2. Apply the cap to the tank in accordance with paragraph 9.2.1.1 or 9.2.1.2). 9.2.1.1 Place cap over lifting lug. Pre -mix resin with catalyst and apply around the cap and the tank surface immediately adjacent to the cap. Bond the cap to the tank with two layers of fiberglass mat previously saturated with resin. Roll out all air bubbles and air pockets, or as an alternative, see paragraph 9.2.1.2. 9.2.1. re -mix resin with filler material and catalyst. Apply generously to tank surface at lift lug and to bottom of FRP cap, Place cap over lift lug. Apply additional resin with filler and catalyst around edges of cap to seal. AiI& to cure. J 9.2.2 As an alternative to Paragraph 9:2.1, exposed steel at the lift lugs may be covered with the laminate via the repair kit supplied by the manufacturer. 9.2.2.1 Follow the manufacturer's instructions given in the repair kit. 9.3 After application, the installer shall verify that the repair work has cured (adequate material hardness and solidification) prior to backfill. 9.4 After an air test has established tightness, tank fittings shall receive a coat of resin prior to backfill. (Refer to Section 9 for surface '. preparation). Resin coating shall include the entire plug on unused fittings. 9.5 Follow temperature guidelines supplied b the manufacturer for proper catalyst/resin rats and recommendations. Ideally, exterior tempetture shall be within the 60-$0°F (16.5-26,6°C) range. Temperatures below 50°F (10°C) shall require an external heat source to enable a chemical reaction to proceed, 10.0 FINAL SACKFILL 10.1 Homogeneous backfill similar to bedding material shall be carefully placed around the entire tank and to a depth of at least one foot (305 mm) over the tank. (See NFPA 30 and state or local codes for a minimum depth of cover required). 10.2 If laminate damage occurs after holiday testing or during backfiil operation, repairs shall be made in accordance with Section 9. 11.0 MAINTENANCE 00�e Z' 11.1 The primary tank should be inspected monthly for the presence of water. Inspection should
