ENVIRONMENTAL ANALYSIS Land Use and Agricultural Resources Because this alternative would result in the construction of the same facilities at the WQCF,the collection system pipeline, and the recycled water distribution pipelines,this alternative would result in the conversion of 41 acres of Important Farmland. Depending on where the distribution pipeline would be constructed to convey treated effluent from the WQCF to the selected land disposal site this alternative also has the potential to result in the conversion of additional Important Farmland. As such,this alternative would result in similar or greater impacts to Important Farmland impacts compared to the project.[Similar or Greater] Visual Resources This alternative would result in the construction of the same treatment facilities at the WQCF and collection system and recycled water pipelines.Visual impacts associated with these facilities were determined to be less than significant with the project because visual screening(e.g., separation distances, landscaping, fencing)of proposed facilities would be provided.While this alternative would result in the construction of additional pipeline to convey treated effluent to new land disposal areas,this pipeline would be located below ground and would not be visible. As a result,no significant visual impact would occur and overall visual impacts under this alternative would be similar to the project.[Similar] Air Quality The Increased Land Disposal Alternative would result in similar construction-related air emissions because similar levels of construction-related activities would occur in the project area. Operational air emissions would also be similar because the same number of staff would be employed and the same volume of wastewater would be treated at the WQCF. This alternative would not avoid the project's significant and unavoidable odor impacts because the same treatment processes would be employed and no additional mitigation would be available to reduce this impact. Overall,this alternative would result in similar air quality impacts.[Similar] Noise Under the Increased Land Disposal Alternative,new construction would occur,new noise-generating land uses would be developed, and additional traffic would be generated. These impacts would be similar to the project because similar facilities would be constructed and similar construction methods would be employed. Mitigation recommended for the project would reduce noise impacts under this alternative to a less-than-significant level. [Similar] Terrestrial Biological Resources The Increased Land Disposal Alternative would result in the same habitat disturbance impacts at the WQCF and associated with collection and recycled water pipelines. This alternative would increase the amount of pipeline needed to convey treated wastewater to off-site land disposal areas. Depending on where the land disposal areas are located,this alternative could result in the construction of up to 10 miles of additional pipeline. Construction activities associated with the additional pipeline could result in the disturbance of sensitive habitats and species along its alignment.While mitigation recommended for the project and compliance with the San Joaquin Multi- Species Habitat Conservation Plan would likely reduce impacts to these habitats and species to a less-than- significant level,this alternative would result in greater impacts to biological resources.[Greater] Hazards and Hazardous Materials Under the Increased Land Disposal Alternative,new development would occur; therefore,new facilities that use hazardous materials would be located in the project area and new workers or visitors would have the potential to Manteca WQCF and Collection System Master Plans EIR EDAW City of Manteca 7-7 Alternatives to the Proposed Project
