Dear Andy:
SUBJECT:
WELLHEAD PROTECTION RESPONSE TO SITE PLAN TENTATIVE
#DRC2010-00023 JACKSON'S FOODS
Tax Map 17-03-22-20, Tax Lot 901, 3375 Gateway Street
The proposed convenience store development is within Springfield's adopted Drinking Water
Protection Area. This area is highly susceptible to contamination from chemicals that may spill or
leak onto the ground surface. Any chemical spills or leaks must be cleaned up immediately and
clean-up materials disposed off-site and in accordance with Lane County and DEQ requirements. In
every case, care shall be taken to prevent groundwater contamination.
This property overlies portions of the 1- 5 year time-of-travel (TOT) zone to the Sports Way Well.
DNAPL chemicals are prohibited at this site (DNAPL list attached.)
GENERAL CONSTRUCTION:
DNAPL Prohibition: The contractor and all subcontractors are required to provide the owner's
engineer with copies of MSDSs for all chemicals proposed for use on-site prior to use or delivery to
the property. Based on these MSDSs, the engineer will determine if the chemical is approved for
use on this site (i.e., whether or not the product contains DNAPLs).1 The engineer may contact the
SUB Water Quality Protection Coordinator (744-3745) with any questions about evaluating
products for DNAPLs. A copy of the MSDS for all chemicals used on the project will remain on the
job site as required by law.
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
equipment located outside from leaking, including providing 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 soil or storm water drainage system.
No fill materials containing hazardous materials shall be used on this site.

OPERATIONS:
Any modifications to the existing facility must comply with the existing Drinking Water Protection
Overlay District Permit. All hazardous materials that pose a risk to groundwater, including items
for retail sale, shall be kept in secondary containment. Sealants used in containment areas should
be resistant to the chemicals stored within them. If the floor will be used to provide secondary
containment, plans shall be approved by SUB Water Quality Protection prior to installation.
The existing hazardous materials management plan (HMMP)and hazardous material inventory
statement (HMIS) shall be amended to include all chemical products to be included in the expanded
inventory. All hazardous material storage areas shall be identified in the facility plan in the HMMP
and shall be provided with secondary containment. The store's current policy is not to keep any
hazardous products (Le., motor oil) outside. Any changes to existing plans shall be included in the
updated HMMP and submitted for approval by SUB.
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 drainage
system. If applicable, chemicals stored outdoors (fertilizers, pesticides, etc.) should be covered and
placed in secondary containment.
STORMWATER
SUB recommends that the base of the bioswale include a constructed medium comprising a
mixture of sand, native soil, loam, and compost. The fraction of organic carbon (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 should
be placed in addition to the required growing medium.
Feel free to contact me at 541-744-3745 for further details or with any questions.
Sincerely,
