<br />19. Water Quality-Wastewaters <br />a. Describe sources, quantities, and composition (except for normal domestic <br />sewage) of all sanitary and industrial wastewaters produced or treated at the <br />site. <br /> <br />The precise nature of the wastewaters to be produced at the site will not be known until <br />the specific tenants of the office/manufacturing space are identified. However, commercial <br />space of this nature does not typically produce wastewater of an unusual nature, or <br />wastewater requiring pretreatment facilities. <br /> <br />b. Describe any waste treatment methods to be used and give estimates of <br />composition after treatment, or if the project involves on-site sewage systems, <br />discuss the suitability of the site conditions for such systems. Identify receiving <br />waters (including ground water) and estimate the impact of the discharge on the <br />quality of the receiving waters. (If the discharge may affect a lake consult "EAW <br />Guidelines" about whether a nutrient budget analysis is needed.) <br /> <br />No sanitary wastewater treatment (pretreatment) facilities are planned for the site. <br /> <br />c. If wastes will be discharged into a sewer system or pretreatment system, identify <br />the system and discuss the ability of the system to accept the volume and <br />composition of the wastes. Identify any improvements which will be necessary. <br /> <br />Normal wastewater typical of commercial and light industriaVmanufacturing will be <br />generated as part of this project. Sanitary waste from the site will be discharged to a large <br />(30-inch diameter) City of Roseville sanitary sewer line flowing north along Long Lake <br />Road. With a slope of 0.10 percent, that line can accommodate flows up to approximately <br />6,000 gpm. Detailed analysis of the existing flows in the system have not yet been carried <br />out. However, it is not expected that improvements to the existing sanitary sewer system <br />will be necessary to accommodate the relatively minor (45 gpm average) flow anticipated <br />from the proposed development. <br /> <br />If tenant(s), not currently identified for the proposed light industriaVmanufacturing space, <br />generate hazardouslharmful waste, the tenant will be required to obtain all necessary <br />permits for handling, storing, and disposing of the hazardouslharmful substance. <br /> <br />20. GJround Water-Potential for Contamination <br />a. Approximate depth (in feet) to groundwater (water table): <br />40 minimum; 45 average. <br /> <br />b. Describe any of the following site hazards to ground water and also identify them <br />on the site map: sinkholes, shallow limestone formationslkarst conditions; soils <br />with high infiltration rates; abandoned or unused wells. Describe measures to <br />avoid or minimize environmental problems due to any of these hazards. <br /> <br />Current residents on the southern parcel and former residence and business on the <br />northern parcel have or had wells that may not have been abandoned. Unused wells of <br />known location will be abandoned prior to development. The locations of the wells for the <br />former residences and business are unknown; if these wells are encountered during <br />development, they will be abandoned. <br /> <br />23624~1 \48185-1IrMN <br /> <br />10 <br />
