REGION-AL—VLA-STEWATER TREATMENT PLANT EXPANSIONS <br />The artificial wetland was selected during the last update of the master plan ( with the Boards <br />direction) for the primary means of effluent disposal for the West Regional Wastewater Treatment <br />Plant. The wetland will have an even greater importance as wet weather disposal for all the <br />county's wastewater treatment plants. This direction has been chosen in lieu of its original "deep <br />well" plan for wet weather disposal (See WRWWTP Wetlands). The County has long been in the <br />business of reuse for effluent disposal and, in fact, has now constructed the beginnings of a fully <br />interconnected and remotely controlled distribution system (See Effluent Reuse Transmission <br />System).The method of effluent disposal sets the limits of treatment for the wastewater plants. <br />With the treatment level set, staff began to evaluate various processes based on the following: <br />** capital costs <br />** operation costs <br />* * treatment flexibility <br />** best fit with existing tankage <br />A modified extended aeration process was chosen with technology and process warranties <br />provided by a "patented Kruger process" (please refer to the enclosed report by W.F. McCain <br />and Rick Johnson with associated exhibits). With this treatment process, we can easily generate <br />effluent of a quality suitable for reuse and with minor modification we can generate effluent for <br />the wetlands. (Reference wastewater overview, detailed process diagram, typical type plant <br />layout 1&2, wetlands pond & plant). The selected process was a modified extended air process <br />and is monitored/contolled by the levels of dissolved oxygen at various critical locations in the <br />process train, and is computer controlled. <br />Permitting and Water Quality Mana eg ment <br />Environmental Engineer Robert Wisemen displayed a printout of <br />one DEP permit application, explained that each and every <br />application is at least that large, and went into some of the <br />standards for water quality management and permitting as follows: <br />I. PERMITTING MANAGEMENT <br />Permitting is extremely involved not only in applying for and <br />obtaining the permit, but also adhering to its requirements <br />during the effective period. This process will be discussed <br />in the maintenance of permits section a little later on. <br />After obtaining a permit, there are many specific conditions <br />26 66 U r <br />FEBRUARY 3, 1997 <br />
