1.0 Purpose
Meet the Phase II Western Washington Secondary Stormwater Permit requirements.
2.0 Scope
The Clark College Stormwater Management Plan (SWMP) applies to all employees
and contractors who are involved in the production and management of waste
material requiring proper disposal, and prevention measures to ensure that public
health is not at risk and the environment is safeguarded from toxic chemicals. The
College SWMP will also educate students and employees on waste water
management in an effort to raise pollution prevention awareness in the college
community.

Illicit Discharge Detection and Elimination
5.3.1
Clark College will comply with local ordinances, rules, and regulations
that govern non-stormwater discharges. By June 24, 2010, Clark College
will develop, adopt and enforce appropriate procedures prohibiting
illicit discharges and illegal dumping. These procedures will address, at
the minimum: illicit connections, non-stormwater discharges and
spilling, dumping, or otherwise improperly disposing of hazardous
materials, pet waste, and litter.
5.3.2
The following sources may be discharged to the stormwater system:
5.3.2.1
Non-stormwater discharges covered by another NPDES permit
5.3.2.2
Discharges from emergency firefighting activities
5.3.2.3
Rising ground waters
5.3.2.4

5.3.3.2
Discharges from lawn watering and other landscape irrigation
runoff.
5.3.3.2.1
These discharges are reduced through limited irrigation
occurring only in the summer months. Irrigation schedules

Street and sidewalk wash water, water used to control dust, and
routine external building wash down that does not use
detergents.
EHS
Page 5
5.3.3.3.1

cleaned with a high pressure washer. A street sweeper is
used to clean parking lots. Water is conserved to the
maximum extent practicable, and no chemicals are used.
5.3.4
The Clark College Spill Prevention Control and Countermeasures Plan is
incorporated by reference as the spill response plan.
5.3.5
Facilities Services will be trained in the prevention of spills and illicit
discharges. Training will be as needed and may be presented in a
variety of formats, including, but not limited to, pamphlets, classroom
and online.
5.4
Construction Site Stormwater Runoff Control
5.4.1
It is anticipated that all construction activities that disturb one or more
acres of land and require a Grading/Tree Protection/Erosion Control
Plan will be completed by a contractor.

The contractor will obtain and comply with the Grading/Tree
Protection/Erosion Control Plan.
5.4.3
Clark College Project Managers will monitor compliance with the
Grading/Tree Protection/Erosion Control Plan for their projects and
promptly notify the contractor of any deficiencies.
5.5

5.6
The College will comply with applicable regulations governing post
construction stormwater pollution prevention.
Pollution Prevention and Good Housekeeping Operations

EHS
Page 6
runoff treatment and/or flow control facilities will be
inspected annually and maintained as needed.
5.6.1.2
5.6.1.2.1
The Facilities Services Snow Removal plan is incorporated
by reference. Deicer is stored in Facilities Services and is
applied primarily on sidewalks and walkways when the
temperature is predicted to drop below freezing.

Facilities Services monitors parking lots daily to remove
trash, litter and debris.
5.6.1.3
5.6.1.3.1

Facilities Services is responsible for most exterior building
maintenance. Approximately every 5 to 10 years, the
exterior of the buildings are pressure washed with water.
Buildings are sealed with a water based concrete sealer
every 10 years. Pressure washing is done during summer
months to limit the impact to the stormwater system.
5.6.1.4.2
Facilities Services cleans exterior windows and building
entrances. Neither activity is expected to impact the
stormwater system.
5.6.1.5
5.6.1.5.1

Parking lots
Exterior open spaces
Facilities Services maintains the open areas of the College.
The Clark College Integrated Pest Management Plan is
incorporated by reference. Garbage cans are readily
available outside, and garbage and litter are picked up daily.
Material storage areas, heavy equipment storage areas, and
maintenance areas
EHS
Page 7
5.6.1.6.1
Heavy equipment is typically stored under cover and should
not impact the stormwater system. Likewise, the
maintenance areas are also under cover and should not
impact stormwater. Most materials are stored under cover,
however stockpiles of sand, bark and gravel are stored in
exterior piles. Facilities Services routinely checks the
stockpiles to ensure they are not impacted by storms.
