18. Water Quality: Wastewaters <br /> <br />a. Describe sources, composition and quantities of all sanitary, municipal and <br /> industrial wastewater produced or treated at the site. <br /> <br />Wastewater generated by the operation of the proposed sand and gravel mine will include <br />sanitary waste from workers or employees of independent trucking companies. Portable <br />self-contained sanitary facilities will be provided and maintained weekly by an <br />independent company during the annual operating months. During non-operating months <br />the portable facilities will be removed. No wastewater will be discharged as a result of <br />the mining operations. No other wastewater will be generated at the Site. <br /> <br />DJ <br /> <br />Describe waste treatment methods or pollution prevention efforts and give estimates <br />of composition after treatment. Identify receiving waters, including major <br />downstream water bodies, and estimate the discharge impact on the quality of <br />receiving waters. If the project involves on-site sewage systems, discuss the <br />suitability of site conditions for such systems. <br /> <br />Not applicable <br /> <br />Co <br /> <br />If wastes will be discharged into a publicly owned treatment facility, identify the <br />facility, describe any pretreatment provisions and discuss the facility's ability to <br />handle the volume and composition of wastes, identifying any improvements <br />necessary. <br /> <br />Not applicable <br /> <br />do <br /> <br />If the project requires disposal of liquid animal manure, describe disposal technique <br />and location and discuss capacity to handle the volume and composition of manure. <br />Identify any improvements necessary. Describe any required setbacks for land <br />disposal systems. <br /> <br />Not applicable <br /> <br />19.
