chemicals that may spIll or leak onto the ground surface Any chemical spills or leaks must be cleaned up tmmedlately and cleanup matenals disposed oft-site and m accordance With Lane County and DEQ reqUirements In every case, care shall be taken to prevent groundwater contammatlOn ThiS property overlIes portIOns of the 5 - 10 year lIme-of-travel (TOT) zones to the SPI Well It IS Important to note that DNAPL chemicals are prohibited at thiS site (DNAPL and Exempt Lists attached) GENERAL CONSTRUCTION DNAPL PlolubttlO1/ The contractor and all subcontractors are reqUired to provide the owner's engmeer With copies ofMSDSs for all chemicals proposed for use on-site pnor to use or delIvery to the property Based on these MSDSs, the engmeer will determme lfthe chemical IS approved for use on thiS site (I e , whether or not the product contams DNAPLs) The engmeer may contact the SUB Water Quality ProtectIOn Coordmator (744-3745) WIth any questIOns about evaluatmg products for DNAPLs A copy of the MSDS for all chemicals used on the project Will remam on the Job site as required by law Chemical handilng, 'torage, and use Contractors/developers shall be responsible for the safe handlmg and storage of chemicals, petroleum products, and fertilIzers and the preventIOn of groundwater and storm water runoff contammatlOn Chemicals used dunng constructIOn, mcludmg pamt and cleanmg matenals/wastes, must not enter the SOlI or be washed mto the storm water system All chemIcals should be stored m adequate secondary contamment Eqlllpment mall/tenana and fueilng PrecautIOns must be taken to prevent flUld-contammg equipment located outSide from leakmg, mcludmg provldmg a dedIcated area for fuelIng and maintenance of eqUIpment This area should be prepared and maintained In a way that prevents spIlls or leaks from mIgrating to the SOlI or storm water drainage system No fill matendls containing hazardous matenals shall be used on thIS sIte OPERATIONS As shown In the site plan draWings, dumpster areas should be covered and contained to aVOId wastes from leaking Into the SOlI or storm water system Vehicle storage areas should be deSIgned to prevent any leaks or spills from entenng the soIl or storm water drainage system As shown In the sIte plan draWings, runoff from parking areas should pass through a system of catch baSinS, OIVwater separators, and blO-swales before entenng the CIty's storm water drainage system These plans need to be approved by the City of Spnngfield A DWP Overlay DiStrIct applIcatIon wIll be requIred for thIS faCIlIty CondItIons of the DWP

process Rooftop mounted equipment and other flUId-containing eqUIpment located outSIde the bUIlding should be sealed and proVided WIth secondary containment or a weather resIstant enclosure In the event of a spill or leak, thIS wIll prevent any flUIds from migrating Into the storm water dramage system If applIcable, chemIcals stored outdoors (fertIlIzers, pestICIdes, etc ) should be covered and placed In secondary containment STORM WATER Storm water from parking and landscape areas should be routed to discharge to an infiltratIOn system that Incorporates vegetatIve treatment methods These plans need to be approved by the CIty of Spnngfield BIO-swales, such as ImplIed In the workmg draWings for thIS SIte, are an excellent way to retard the infiltratIOn of runoff SOlIs lIning the swale(s) may need to be amended WIth clay as a means of further redUCing their permeabIlity A sub-surface layer of heavy clay SOlis bencath the planting beds would also serve the purpose of dIrecting excess mOIsture containing fertIlIzers and/or pestiCIdes from porous planting medIa Into the blO-swale(s) Becau~e the faallty WIll be a dlS/nbutlOlls cellter, protectIve measures at loadlllg dOLks are es~ellt/Ql for protectlllg drlllklllg water GUIdelInes for deSIgning loading docks to contain spIlls of hazardous substances and prevent contaminatIOn of stormwater runoff mclude connecting catch
