Based on a review of <br /> the EHD septic permits, the site is equipped with one septic system. The vicinity of the site ` <br /> consists of agricultural land, rural residences, and industrial facilities. The assumption was made <br /> that each building/cluster of buildings has one septic system. Using this method, we determined <br /> there is an average of twenty septic systems located within one half mile of the site. <br /> 1.3.5 Septic Permit History in the Vicinity <br /> Septic permits on file with the EHD were requested for the adjoining properties surrounding the <br /> site.
