Installation of a Nevr Gate an EI tri I9 h Tr t <br /> re <br /> � nt Co DVDMAn <br /> In order to install and provide access to the carbon reactors for treatment of the extracted <br /> vapors,a gate was installed facing Waudman Avenue which opens the entire fourteen foot <br /> length of the compound (See Figure 3). A 200 amp single phase 220 volt service with <br /> eight circuits already existed as power supply for the fenced treatment compound. f=our <br /> 'µ unused circuits were modified with 40 amperage circuit breakers and wired through <br /> outdoor rated watertight switching boxes to the four regenerative blowers. Due to limited <br /> _. space in the treatment compound, the blowers were mounted on a two-shelf rack <br /> constructed of Super-StrutTM, two blowers per shelf. The fenced area is secured with a <br /> combination padlock and visually isolated using wooden slats interspaced in the chainlink. <br /> Va or Extraction S stem Installation <br /> The VES consists of three groundwater monitoring wells (MW-1, MW-3, and MW-4), one <br /> groundwater recovery well (RW-1), and the previously installed vapor wells (VP-1, VP-2, <br /> VP-3, and VP-4). MW-1, MW-4, and RW-1 are each individually manifolded to a high <br /> �- capacity regenerative blower (one for each well). MW-3, VP-1, VP-2, VP-3, and VP-4 are <br /> manifolded to one regenerative high capacity blower with variable flow ball valves to <br /> control vapor flow from each well. Each of these blowers are capable of removing up to <br /> 160 standard cubic feet per minute(SCFM)of vaoose zone vapor. The combined effluent <br /> from these blowers is manifolded into the activated carbon adsorption system. <br /> 4 <br /> VAPOR EXTRACTION TECHNOLOGY, INC. <br />
