STORMWATER POLLUTION PREVENTION PLAN

5148 Auburn Way North
Auburn, WA
SEPA # SEP 01-0018
GRA # GRA 01-0017
Parcel # 936000-0199
Introduction :
The following is a stoem water pollution prevention plan for Automotive
Express. The project is located on the north east corner of Auburn Way
North and S. 277te Street in Auburn Washington.
t~? The site area is 0.77 acres and currently developed as an existing used
car dealership. The site is currently located within the 100 year flood
plain (elevation '45) and contains an existing 2 story building,
c., landscaping, asphalt and gravel parking. The site has been previously
a permitted under GRA 0021-99 to do some minor filling of the site while
providing an equal "flood compensation area" on the site. However, the
c~ southern portion of the site was completely filled with class `A'
structural fill and graveled by the owner to create a large parking /
r display area for the sale of used cars within the 100 year flood plain.
This unauthorized fill was seen or brought to the attention of the City
` of Auburn's public works department. After many correspondences and
c meetings with the City of Auburn, it was determined the unauthorized
fill has to be removed from the site and cannot be done without a
new/revised grading plan and a complete SEPA application. This report
is being prepared concurrently with SEPA and the Site/Grading plan.
The new Site/Grading plan is proposing to remove all of the unauthorized
fill, and add 3,421 SF of additional asphalt pavement to the north side
of the building. In addition to the removal of the fill we will over
excavate the 'area by 307 cubic yards for flood plain compensation for
additional filling of the north side of the building. I have met and
discussed with Tim Carlaw the requirements for adding the additional
square footage of impervious area to the site. He determined that he
wants us to provide equivalent storage volume equal to the increased
storm water volume for the developed 100-year storm and add two catch
basin inserts for water quality. This volume has been calculated and is
satisfied with the proposed addition of 80 feet of 24" PVC pipe. The
water is collected in an Stormwater Management catch basin insert prior
to detention for water quality.
Plan Goal
The specific purpose for the storm water facility is to minimize
pollution that is typically associated with modern development. In
general, pollution from motor vehicles and pollution generated from
erosion. Attached to this narrative is a maintenance manual which
offers guidelines to the owner for storm water facility maintenance.

Prevention BMP'S
The catch basins shall have stenciled on them "DUMP NO WASTE - DRAINS TO
STREAM. The owner shall be responsible for sweeping the lot, installing
storm drainage stenciling and provide spill control procedures. In case
of spill call 1-425-649-7000. The catch basins, detention pipes, and
control structures will be visually inspected for accumulation of debris
and silt and will be maintained as required by this pollution prevention
plan and attachments.
* Maintenance Standards for Drainage Facilities

No. 4 - Control Structure/Flow Restrictor
No. 5 - Catch Basins
(Department of Ecology Storm Water Manual, August 2001).
* Stormwater Management catch Basin Insert with Cartridge
* Attached Information
Treatment BMPIS
Two on-site Stormwater Management catch basin insert with cartridge have
been installed to treat runoff for conventional pollutants. The catch
basin inserts with cartridges were designed to treat 64% of the 2-year
storm event (water quality storm) for water quality treatment. In
addition, the added detention pipe volume was sized to convey runoff for
the additional volume created from the existing to the developed 100
year event / storm volume.
The City of Auburn Utilities Section is to review and approve any
changes to this stormwater Pollution Prevention Plan prior to changes in
its implementation. Additionally, any changes in ownership or person of
ccr responsibility are to be reported to the City Utilities Sections.

Inspection / Maintenance Instructions:
Regular inspections of the drainage facilities should be carried out twice per
year, in the spring and fall. The stormfilter cartridges must be replaced
once a year (min.) or as needed. The owner shall keep a record of inspection
and maintenance for a period of 5 years and will provide a copy of the records
and maintenance checklist for the City Inspector to review. Additional
inspections may be required after severe seasonal storms.
Routine maintenance of the site will include mowing, care of landscaping and
the removal of trash and debris from the drainage system. The parking lots
and driveways should be kept clean and in repair. Events such as major storms
or heavy winds will require immediate inspections for damages.
To ensure proper water quality and treatment, the detention tank and the Catch
basin inserts must be properly maintained per the attached information.
Ac~j
c::- Catch Basins shall be cleaned when sump is 1/3' full of sediment or debris.

Brief Description of Maintenance Procedures
Stormwater Management Inc. can provide maintenance services completely, or in part.
Available services include tracking of installed systems, advising the system owner of
maintenance needs and notifying the regulatory agency once the system has been
maintained and inspected.
Maintenance is usually performed late in the dry season to rejuvenate the filter media
prior to the upcoming rainy season (annual maintenance). Maintenance may also be'.
required in the event of a chemical spill or if an excessive solid loading occurs due to
erosion or extreme storms.
Appendix A provides the full StormFilter Operation and Maintenance manual. The
following highlights minor and major maintenance recommendations and provides
insight for determining maintenance frequency.
STORM FILTER MAINTENANCE - MINOR
1) Inspect the system for structural integrity (internal and external components)
2) Remove collected debris"from filter unit if obstructions to filtration may occur
3) Record to condition of the unit to determine if major maintenance is needed (See
cca Determining When StormFilter Major Maintenance is Needed, below.)
QN&
STORMFILTER MAINTENANCE - MAJOR (BRIEF OUTLINE)
o .
1 StormFilter maintenance is typically
performed using a single cartridge pick (4"
QN. Schedule 80 PVC threaded end cap, SMI provided) and a crane to remove the
cartridges. The crane is not necessary for cartridges that are removed via Vactor
a:
truck within the vault, however, an increase for liquid waste disposal will be
incurred.
C=t 2) After cartridge removal, accumulated sediments can be removed with a Vactor
truck or a square nose shovel and a large container
3) Once accumulated sediments are removed, the vault is inspected for structural
conditions and recharged cartridges are then inserted.
4) Collected sediment and spent media are disposed of off site (typically.a landfill or
wastewater treatment facility). SEE Operations and Maintenance Guidelines -
StormFilter [Appendix A]
DETERMINING WHEN STORMFILTER MAJOR MAINTENANCE IS NEEDED
1) Sediment accumulation on top of cartridge is an indication that the influent
water is not passing through the cartridges at the design rate (i.e. suspended
sediment has time to settle out rather than being filtered).
2) Scum line in relation to height on vault wall. If the scum line is at or below the
overflow elevation, which is at the invert of the downstream flow spreader, then
the system has not been loaded to the point where overflow has occurred.
Storm Water Easement and Maintenance Agreement
Page 10 of 14
3) Accumulated sediment on floor of 114" usually indicates full maintenance is not
required. Sediment accumulations of or greater typically warrants full
maintenance.
4) If the cartridges are in standing water, this is direct evidence that the
cartridges are completely plugged. However, the inspector needs.to insure that
the cartridges are not submerged due to backwater conditions caused by high
ground water, plugged pipes or high hydraulic grade lines. Completely plugged
cartridges also can be associated with heavy O&G loading from animal and-
vegetable.fats or petroleum hydrocarbons: If this is the case-source control
measures are warranted:
5) Media'appearance - Perlite media is extremely white when put in placer When
this media becomes darkened to the point of almost being black, maintenance is
needed. CSF Leaf media will become impacted with sediment such that no
interstitial spaces are between the granulated media.
6) A history of the facility is kept in maintenance files. This history allows' for an
understanding of maintenance requirements over time.

Maintenance Standards for Drainage Facilities
The facility-specific maintenance standards contained in this section are intended to be
conditions for determining if maintenance actions are required as identified through
inspection. They are not intended to be measures of the facility's required condition at all
times between inspections. In other words, exceedence of these conditions at any time
between inspections and/or maintenance does not automatically constitute a violation of
these standards. However, based upon inspection observations, the inspection and
maintenance schedules shall be adjusted to minimize the length of time that a facility is in
a condition that requires a maintenance action.
