Dear Mr.Longanecker:
Thank you for the opportunity to comment on the mitigated determination of nonsignificance for the
construction of a Safeway gas station consisting of a 325 square foot kiosk,a fueling canopy with 5
dispensers and 2,20,000 gallon underground fuel storage tanks,with related site work including parking
spaces and landscaping(Case No.SEP2001-0020)located on the north side of Clifton Lane at the entry of
the Safeway parking lot as proposed by Inform,Inc. We reviewed the environmental checklist and have
the following comments:
Air Quality
Applicant should coordinate with the Olympic Air Pollution Control Authority.
Undereround Storaee Tanks:
Installation of new underground storage tanks must meet the requirements of the state underground
storage tank regulations(Chapter 173-360 WAC). Copies of these regulations and required forms are
available from the Department of Ecology by calling(360)407-7202,or toll-free instate 1-800-826-7716.
A notice of intent to install tanks must be filed with the Department of Ecology at least 30 days prior to
installation. Within 30 days after coming into service,the tanks must be registered with the Department
of Ecology on a state notification form.
The supervisor on-site during the installation must be licensed by passing an exam administered by the
International Fire Code Institute,or by another state with which Washington has a reciprocity agreement.
New tanks and any connected piping must be protected from corrosion by either a cathodic protection
system,or by being constructed or coated with a non-corrosive material such as fiberglass. An acceptable
method of leak detection must be employed,and the tanks must be equipped with spill prevention and
overfill protection equipment.
Stage I vapor recovery equipment is required on all new gasoline dispensing facilities with a total
gasoline nominal storage capacity greater than 10,000 gallons. Also,a certified Stage II vapor recovery
system may be required for these facilities in all Western Washington counties(Chapter 173.491 WAC).

Under the Uniform Fire Code, other local permits may be required for the installation of underground
storage tanks. The local official charged with administration of the Code should be contacted regarding
the permit requirements.
Water Quality:
Oil/water separators should, at a minimum, be designed, operated, and maintained in accordance with
Ecology's Stormwater Management Manual for the Puget Sound Basin" February 1992. This includes
routine inspection and maintenance of the separator and establishing a written log of such activity.
Discharge from all oil/water separator should not exceed the state guidelines established for discharges
containing oil and grease of mineral origin.
