Report of Findings—Dairy Waste Removal Page 3 Teixeira—Souza Dairy November 27,2006 WKA No.6504.07 Visual Observation of Waste Removal Waste removal activities conducted by ALP consisted of pumping liquids from the wastewater and drainage ponds to access the sludge and waste for removal, excavation of the dairy waste, and removal of existing structures to access the underlying waste. Observation of the excavation activities included identifying soil that had been impacted by operations at the dairy, typically in the form of excess organics and buried debris, and requesting that it be removed. Any encountered buried debris was separated from the manure and impacted soils. During the initial phase of waste removal, waste was identified as extending below several of the structures. These structures were removed so the underlying waste could be excavated. Significant quantities of waste were removed from beneath the footprints of the former barn, corrals, and animal holding areas (Figure 2). Waste and sludge were removed from the wastewater and drainage ponds to a depth just above groundwater(approximately 12 feet below ground surface). The waste removal process continued until no visible organic material associated with the former dairy was present in any exposed soil. Waste Spreading Excavated waste, manure, sludge, and impacted soil were subsequently transported and spread on the adjacent agricultural fields,to the west of the former dairy, a typical dairy operation and maintenance practice. The waste was then disced into the native soil to facilitate breakdown of the organic material. Visual Confirmation of Waste Removal Following excavation and removal of all identified waste, WKA representatives visually inspected soil conditions to determine if all waste and impacted soil had been removed from the former dairy. Visual inspection included hand excavating below the existing grade across the Site or below the areas where waste had been removed to confirm that removal activities were effectively implemented. Visual inspection was also conducted during the spreading activities to ensure the waste was not being spread too aggressively to reduce the effects of the natural breakdown of the organic material.
