Other benefits of the proposed technology are that it generates no z" mAst01d"w*k, <br /> wastes, requires no power or fuel, is simple and non-disruptive to implement and maintain, and Th Vw4p' � a-( <br /> �? can be substantially more cost-effective than other remedial options. femZ <br /> pi cns�d <br /> 13 .Levi <br /> bd.( <br /> Floyd Barnes 7 Updated CAP <br /> ZB 178 Update to CAP March 2010 <br />
