off contamination and segregate contaminated flows from non- <br /> contaminated precipitation. However , the problem of excess <br /> precipitation disposal reinains. Marley is actively seeking <br /> t regulatory agency guidance at this time regarding this disposal <br /> !i problem. Marley 's preliminary plan on this subject follows. <br /> i <br /> j The EPA's effluent guidelines for the Water Borne- Inorganic Salts <br /> j subcategory of wood preserving industries stipulates zero <br /> discharge for process wastewaters associated with this industry. <br /> The effluent guidelines development document for this industry <br /> stipulates that process wastewaters include spills, drips, etc. <br /> associated with the pressure treating of the wood in the retort <br /> and drip areas and contaminated precipitation which accumulates <br /> in these areas . Marley accepts this definition and has <br /> instituted, or is in the process of instituting, process changes <br /> and construction of precipitation containment structures and <br /> liners in the retort/drip areas. Preliminary water mass balance <br /> calculations indicate that these "process wastewaters " can be <br /> recylced to the process , and hence , will not require further <br /> disposal options ( i .e. zero discharge can be met for these <br /> waters ). <br /> The zero discharge requirement becomes prohibitive when run-off <br /> from other areas of the storage yard are considered, andit is <br /> here that we seek relief from such requirements. At a minimum, a <br /> — permit for direct discharge of non-contaminated storm water run- <br /> off will be required. Marley also anticipates that a discharge <br /> 10 <br /> t <br />
