The primary tank shall be mounted within the secondary containment cabinet by means of at least four (4) stabilizing brackets to prevent the primary tank from shifting. 2.6. The primary tank shall be placed within the secondary containment cabinet with a minimum of 3" visual clearance around all sides to allow for 100% visual inspection . 2.7. The exterior of the primary tank shall be cleansed of foreign material, and coated with a corrosion resistant industrial paint (3 to 5 mils dry film thickness). 3. ENVIRONMENTAL TANK ENCLOSURE: 3.1 . The Environmental Enclosure (secondary leak containment tank) shall be rectangular in design and constructed with a minimum 12 ga. steel. All welds shall be full penetration . 3.2. The Environmental Enclosure shall be separate from the primary tank, and shall not be welded or attached to the primary tank in any fashion . 3.3. The secondary leak containment tank shall completely enclose the primary tank and all operating equipment (3600 radius), providing secondary containment to the primary tank and operating equipment, It shall be sized to contain 110% of the primary tank storage capacity. 3.4. The inside bottom of the secondary tank shall be fitted with a minimum of two (2) raised steel channels (a minimum of 2" in height), to support the primary tank above the secondary tank floor. 3.5. The secondary tank shall be supported by two (2) 4" high steel support feet channels with integral anchoring holes to maintain ground clearance for better anchoring to concrete fo •andation . 3.6. The secondary tank shall contain a removable, locking roof that provides at least 30" of clearance from the top of the primary tank to the bottom of the roof. 3.7. The secondary containment cabinet shall contain louvered vents on the cabinet, which is above the level of the primary tank. These vents shall provide a minimum of 20" of venting capacity. 3.8.
