Dear Steve
The proposed Aramark development IS wlthm Spnngfield's adopted Dnnkmg Water ProtectIOn
Area ThiS area IS htghly susceptible to contammatton from 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
permit Will Include stonng all chemlcals/hazardous matenals In appropnate secondary
containment Sealants used In containment areas should be compatIble WIth chemicals stored
WIthin them Again, DNAPL chemIcals are prohIbited Chemicals used on site and stored off
Site, such as landscaping matenals, WIll need to be reviewed Please contact me (5417443745)
WIth any questIOns about the DWP applIcatIOn 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 baSinS to the samtary sewer, covenng areas directly over loading docks, installIng cut-off
trenches up-gradIent to the catch baSinS to dIvert rainwater from entenng the samtary sewer, and
eqUIpping samtary drainS WIth emergency valvlng to prevent the aCCIdental dIscharge of
hazardous matenals
All injectIOn wells (If applIcable) must be approved by both the CIty of Spnngfield and DEQ
based on proXImIty to domestIC/publIc dnnklng water wells, SOlis type, and depth to groundwater

(dunng construcl1on and operatIOns) adjacent to loadmg docks, parkmg lots, trash enclosures, and
elsewhere on the slte to alert contractors, subcontractors, employees, and others to the lmportance
ofreportmg and cleamng up any spllls (Slgn standmd attached) Please contact Amy Chmltz
