2.1.3. Materials 2.13.1. The tank shall be manufactured as a matrix of premium resin,glass fibers and silane-treated silica that together result in a composite providing improved corrosion protection. 2.1.3.2.Tank inner wall shall be fabricated against a mold to produce a non-air inhibited and high gloss laminate to provide a fully cured inner surface without the need for wax coats,a low coefficient of friction and a natural resistance to the build-up of algae or other contamination on the surface.Wax and wax resin coatings cannot be used to achieve full surface cure on tank shells and endcaps. 2.1.4. Dimensional Requirements(refer to Containment Solutions literature) 2.1.4.1. Nominal capacity of the tank shall be_gallons/liters. 2.1.4.2. Nominal outside diameter of the tank shall be—feet. 2.1.4.3. Nominal overall length of the tank shall be_feet. 2.1.5. Monitoring Capabilities 2.1.5.1. Double and triple-wall tanks shall have a monitoring space between the walls to allow for the free flow and containment of leaked product from the primary tank.The monitoring space shall provide equal communication in all directions. 2.1.5.2. The following continuous monitoring conditions shall be compatible with the cavity between the inner and outer tanks: • Vented to atmosphere • Vacuum–5 psig maximum • Positive air pressure(3 psig maximum) • External hydrostatic pressure–7'maximum groundwater head pressure over tank top 2.1.5.3.The monitoring system shall be capable of detecting a breach in the inner and outer tank under the following installed conditions: • When the primary tank is empty. • When the primary tank is partially or completely full and the groundwater table is below tank bottom. • When the primary tank is partially or completely full and the tank is partially or completely submerged in groundwater. 2.1.5.4. The leak detection performance of the monitoring system shall be listed as a continuous interstitial monitoring method(liquid filled)by the National Work Group on Leak Detection Evaluations(NWGLDE).The system should be capable of detecting leaks in the primary or secondary tank walls as small as 0.10 gallons per hour within one-month. 2.1.5.5. The hydrostatic monitoring system shall be capable of a precision tank test that is listed by the National Work Group on Leak Detection Evaluations(NWGLDE). 2.1.5.6. If hydrostatically monitored,any solution used in the monitoring space shall be compatible with the tank and be of a contrasting color to the tank. 2.2. Accessories 2.2.1. Flanged Manways 2.2.1.1. The standard manway is 22"I.D.and will be furnished with UL listed gaskets and covers(30"and 36"manways are optional). 2.2.1.2. Location–see standard tank drawings. 2.2.13. Optional manway extensions shall be fiberglass and_feet long. 2.2.2. Fill Tubes-Fill tubes of appropriate design shall be supplied by contractor. 2.2.3. Hydrostatic Monitor Accessories 2.2.3.1. Tanks 6'diameter and larger shall have an integrally mounted annular space reservoir installed on the tank for factory-installed brine and continuous hydrostatic monitoring.The reservoir shall be constructed of fiberglass reinforced plastic materials and be included in the tank warranty. 2.2.3.2. The monitoring fitting for the monitoring space shall be a 4"NPT fitting. 2.2.3.3. Brine monitoring fluid shall be a calcium chloride solution. 2.2.3.4. Double float reservoir sensor supplied by contractor shall be designed for CS1 reservoirs.The components of the sensor shall be compatible with brine and provide two alarm points positioned 10"apart. 2.2.4. Secondary Containment Collars 2.2.4.1. Shall be factory installed. 2.2.4.2.The collar shall be fiberglass reinforced plastic,42 48"or 54"in diameter and shall be factory-installed in accordance with drawings. 2.2.4.3. The collar shall include an internal adhesive channel. 2.2.5. Adhesive Kits(Kit AD) 2.25.1. Adhesive kit shall be supplied by tank manufacturer. 2.2.5.2. Adhesive kit shall provide a watertight seal at the tank sump and containment collar joint to prevent the ingress of water or egress of fuel.The adhesive kit includes resin,catalyst,mixing stick,putty knife,sandpaper,grout bag,and installation instructions. 2
