+ V Analysis WetlandsMater Treatment The applicant is proposing to create wetlands/water treatment ponds on the project. site to process wastewater emanating from the winery operations. The wastewater will be processed through a sustainable wastewater.treatment process Called Swanson Advanced Integrated Pond System (Swanson AIDS). This process is very similar to;the one that was part of the approved Use Permit (UP-97-5) application for Sebastiani Vineyards on Turner Road. The proposed treatment ponds are designed and constructed with a liner to seal the internal surfaces, preventing contact between I untreated wastewater.and ground waters. The treatment ponds combine anaerobic.digestion with mechanical aeration and recirculation. These ponds will be used for the primary and secondary treatment of process water. The ponds will only accommodate process wastewater (no sanitary waste) and will be subject to the requirements of the Regional Water Quality Control Board. In a Swanson AIPS pond, wastewater is introduced at the bottom of the digester, which is the initial step of waste treatment. Anaerobic digestion, during this part of the process, produces methane, sulfides, and other volatile gases, which can be offensive if released. The anaerobic zone is capped with an oxygen- rich layer which strips out odors and volatile bio-gases before they can escape into the atmosphere. This precludes the need for mechanical containment or scubbers for these gases. Effluent from a Swanson AIDS is suitable for direct land disposal or irrigation. All this is accomplished prior to the wetlands polishing and storage area. After treatment in these ponds, the water will flow by gravity into the wetlandltreatment ponds for polishing treatment. The constructed wetlands will provide additional treatment to secondary effluent while also providing habitat for wildlife. Treated water within the wetland/treatment ponds may be used for irrigation. Neighborhood„Opposition The Community Development Department has received four letters in opposition to this proposed project. The issues expressed within these letters concern noise, traffic, odors/air quality, lighting, aesthetics, water quality, and wildlife. Noise Development Title Section 9-1025.9(c)(5) states that stationary noise sources are exempt from the noise level standards specified in Table 9-1025.9, Part 11 when the noise sources are emanating from any agricultural operation, including activities associated with the processing or transportation of crops when such activities are conducted on agriculturally zoned lands. The nearest residence is located approximately 800 feet from the proposed truck entrance for the project site and approximately 1,400 feet from the grape presses and dump station_ The proposed perimeter landscaping and oak forest along the western property line will aid in dampening some of the noise coming from the winery. Due to the distance to the nearest residence, it is expected that the noise levels will not exceed acceptable standards for noise emanating from an agricultural operation.
