The tank size, fittings and accessories shall be as shown on the drawings. The fiberglass tank shall be manufactured by Xerxes Corporation. The tank shall be tested and installed according to the Xerxes Installation Manual and Operating Guidelines for Fiberglass Underground Storage Tanks in effect at time of installation. Long form: Part I: General 1.01 Quality Assurance A. Acceptable Manufacturer: Xerxes Corporation B. Governing Standards, as applicable: 1. Underwriters Laboratories (UL) Standard for Safety 1316 Glass -Fiber -Reinforced Plastic Underground Storage Tanks for Petroleum Products, Alcohols, and Alcohol -Gasoline Mixtures. A UL label shall be attached to each tank. 2. National Fire Protection Association (NEPA) Standards: NFPA 30: Flammable and Combustible Liquids Code, NFPA 30A: Code for Motor Fuel Dispensing Facilities and Repair Garages, NFPA 31: Standard for the Installation of Oil -Burning Equipment. 3. City of New York Department of Buildings M.E.A., #161-89-M. 4. American Concrete Institute (ACI) standard ACI 318-11, Building Code Requirements for Structural Concrete. C. Submittals 1. Contractor shall submit _ copies of shop drawings, manufacturer's product brochures, and Installation Instructions. Part II: Products 2.01 Double -Wall and Triple -Wall Fiberglass Reinforced Plastic (FRP) Underground Storage Tanks: A. Loading Conditions - Tank shall meet these design criteria: 1. Interstitial Pressure - The interstitial space of the tank shall withstand a minimum 20 -prig pressure test. 2. Internal Load -Tank shall withstand a 5-psig air -pressure test with a 5:1 safety factor. 3. Surface Loads -Tank shall withstand surface H-20 and HS -20 axle loads when properly installed according to Xerxes' current Installation Manual and Operating Guidelines. 4. External Hydrostatic Pressure - Tank shall be designed for 7' of overburden over the top of the tank, the hole fully flooded and a safety factor of 5:1 against general buckling. B. Product Storage: 1. The primary compartment of double-wall and triple -wall tanks shall be vented and operated at atmospheric pressure only. 2. Tank shall be capable of storing liquids with a specific gravity up 10 1.1. 3. Tank shall be capable of storing products identified in the manufacturer's standard limited warranty in effect at the time of purchase. C. Materials: 1. The primary and secondary walls of the tank shall be manufactured with 100% premium resin and glass -fiber reinforcement. No sand or silica fillers shall be added to the resin. 2. The interstitial space between the primary and secondary walls shall be constructed with a glass reinforcement material such as Parabeame, which provides a structural bond between the two tank walls, while creating a defined interstice that allows for free flow of liquid. D. Tank Dimensions (Refer to Xerxes literature on gallonage): 1. Tank shall have nominal capacity of gallons. 2. Tank shall have nominal outside diameter of feet. 3. Tank shall have a nominal overall length of feet/inches. 2.02 Tank Monitoring System 10 A. General 1. Tank shall be continuously monitored with the TRUCHEK® hydrostatic leak monitoring system. 2. The continuous monitoring system shall include monitoring fluid factory -installed in the interstitial space and within a fiberglass tank -top mounted reservoir. 3. The monitoring system shall be recognized by the National Work Group on Leak Detection Evaluations (NWGLDE) as continuous leak detection and as a precision tank test. 4. The monitoring system shall be independently tested by a qualified third party and verified to be capable of detecting leaks as small as .05 gallons per hour when TRUCHEK tank -tightness test procedures are followed. B. Design 1. The continuous monitoring system shall be designed to detect a leak in either the primary or secondary wall at all times, regardless of the water -table conditions at the installation site. 2. The interstice of the tank shall be designed for a 5:1 safety factor beyond normal hydrostatic operating pressure to ensure structural integrity and to prevent false leak alarms. 2.03 Accessories A. Tank Anchoring 1. Anchor straps shall be as supplied by tank manufacturer and designed for a maximum load of 25,000 lbs. 2. Galvanized turnbuckles (two per anchor strap) shall be supplied by the tank manufacturer. 3. Prefabricated concrete anchors shall be supplied by the tank manufacturer, designed to the ACI 318-11 standard, manufactured with 4,000 psi concrete, and shall have adjustable anchor points. B. Manways 1. The standard manway shall be flanged, 22" I.D. and complete with UL -listed gaskets, bolts and covers as shown on tank drawings. C. Threaded Fittings 1. All threaded fittings shall be NPT half or full couplings, in 2", 4" or 6" diameters. 2. Fittings shall be installed on the tank -top centerline or in the cover of the manway as shown on the tank drawings. D. Containment Collars & Sumps 1. The tank shall have factory -installed 42" -or 48" -diameter containment collars as shown on the tank drawings. 2. Containment sumps in 42" -or 48" -diameter, provided by the tank manufacturer and designed for mounting on the containment collars, shall be supplied as shown on the tank drawings. 3. Adhesive shall be provided by the tank manufacturer with each containment collar and sump. 4. Containment collars and sumps shall be designed and supplied as a containment system. Only sumps provided by the manufacturer shall be allowed. Part III: Testing and Installation 3.01 Testing A. Testing - Tank shall be tested according to the Xerxes Installation Manual and Operating Guidelines in effect at time of installation. 3.02 Installation A. Installation - Tank shall be installed according to the Xerxes Installation Manual and Operating Guidelines in effect at time of installation. Part IV: Limited Warranty 4.01 Limited Warranty A. Limited Warranty - Warranty shall be manufacturer's standard limited warranty in effect at time of purchase.
