The property overlies portions of the 10 - 20 year tiJbe-of-travel (TOT) zone to the Maia Well. This area is highly susceptible to contaminatio'n from chemicals that may spill or leak onto the ground surface. Any chemical spills or leak~ must be cleaned up immediately and clean-up materials disposed off-site and in accordan1ce with Lane County and DEQ requirements. In every case, care shall be taken to prevent groundwater contamination. GENERAL CONSTRUCTION: Chemical handling, storage, and use: Contractors/developers shall be responsible for the safe handling and storage of chemicals, petroleum products, and fertilizers and the prevention of groundwater and storm water runoff contamination. Chemicals used during , construction, including paint and cleaning materials/wastes, must not enter the soil or be , washed into the storm water system. All chemicals should be stored in adequate secondary containment. Equipment maintenance and fueling: Precautions must be taken to prevent fluid-containing I equipment located outside from leaking, including providing a dedicated area for fueling and maintenance of equipment. This area should be prepared and m~intained in a way that , prevents spills or leaks from migrating to the soil or storm water drainage system. No fill materials containing hazardous materials shall be used on thislsite. Dale Ki.Jpeived: "D -;3 Cr -10 Planner: SH . .1 OPERATIONS: The applicant will need to submit either a Drinking Water Protection QDWP) Overlay District application or a DWP exemption: Please contact me (541.744.;3745) with any questions about the DWP permit process. Rooftop mounted equipment and other fluid-containing equipment located outside the building should be sealed and provided with secondary containment dr a weather resistant enclosure. In the event of a spill or leak, this will prevent any fluids fr6m migrating into the storm water drainage system. If applicable, chemicals stored outdoork (fertilizers, pesticides, etc.) should be covered and placed in secondary containm~nt. STORM WATER: The installation of rain gardens is an excellent method for promoting inflltration of clean water into the aquifer, which helps Springfield's water supply. BecauJe the water table at this site is less than ten feet, the following standards apply: . The base ofthe swale shall include a constructed medium comprising a mixture of sand, native soil, loam, and comp,ost. The fraction organic carb:on (foe) in the constructed medium must be a minimum of 0.20 (Le., 40-50%) organic matter. If the growing medium does not conform to this minimum foe requirement, then the constructed medium would be placed in addition to the requi~ed growing medium. . The thickness of the constructed'medium, including or in addition to the growing medium, at the base of the swale,shall be at least 24 inches thitk. Because storm water recharges the aquifer, SUB requests that wellhJd protection signs be placed at the site temporarily during construction and permanently iIi the parking lot and at I the trash enclosure to alert contractors, subcontractors, employees, and others to the importance of reporting and cleaning up any spills (sign standard attdched). Please contact , Amy Chinitz (541-744-3745) if you prefer to purchase signs directly from SUB at the cost of $15jsign. Feel free to contact me at 541-744-3745Jor further details or with any questions. Sincerely, ~L.~ Amy E.
