Tank alarms will be provided in the Control Room to notify personnel when the tank levels are above normal levels. Furthermore, interlocks will be provided from the level measurement transmitters, and are designed to stop flow automatically upon detecting high levels. While unlikely to occur, a network of epoxy coated concreted curbs, trenches, and sumps is designed to collect fluids if a tank overflows or leaks (see H340940-0000-50-015-0008 in Appendix 1-A). High levels in the sumps will be annunciated in the Control Room. Fluids that collect in these sumps will be managed as discussed in Section 22.8.2 and Section 22.8.3. The ASTs will be situated such that the tank may be visually inspected. They will be fixed in place on steel frame skids and provided with secondary containment for at least 100% of the largest tank volume within the area. 23.1 Tanks All tanks will be covered. Tank systems will be designed to prevent the release of any hazardous materials to the environment. Tanks handling hazardous materials will be manufactured of FRP. Tanks will be selected based on suitability for handling of the process fluid. FRP tanks will be built in accordance with the applicable ASME standards. Tank strength and wall thickness are designed to be sufficient for the process fluid(s) intended to be contained in them, and designed to withstand the pressures, temperatures, and stresses of day-to-day operations. Table 23.1-1 identifies the tank dimensions, capacities, and their locations at the proposed TSF.
