Contracting Agency may deem necessary.
If the Contractor fails to comply with a written order to remedy what the Engineer
determines to be an emergency situation, the Engineer may have the defective and
unauthorized work corrected immediately, have the rejected work removed and replaced, or
have work the Contractor refuses to perform completed by using Contracting Agency or
other forces. An emergency situation is any situation when, in the opinion of the Engineer,
a delay in its remedy could be potentially unsafe, or might cause serious risk of loss or
damage to the public.
DIVISION 1: GENERAL REQUIREMENTS
CP1122 1-22 Special Provisions

Direct or indirect costs incurred by the Contracting Agency attributable to correcting and
remedying defective or unauthorized work, or work the Contractor failed or refused to
perform, shall be paid by the Contractor. Payment will be deducted by the Engineer from
monies due, or to become due, the Contractor. Such direct cost s shall include in particular,
but without limitation, compensation for additional professional services required, and costs
for repair and replacement of the Contractor’s unauthorized work.
No adjustment in contract time or compensation will be allowed because of the delay in the
performance of the work attributable to the exercise of the Contracting Agency’s rights
provided by this Section.
The rights exercised under the provisions of this Section shall not diminish the Contracting
Agency’s right to pursue any other avenue for additional remedy or damages with respect to
the Contractor’s failure to perform the work as required.
1-05.10 GUARANTEES Supplement
(September 2013 City of Auburn)
The work performed under these Contract Documents shall be guaranteed for a period of

make a final inspection and the Engineer will notify the Contractor in writing of all
DIVISION 1: GENERAL REQUIREMENTS
CP1122 1-23 Special Provisions
30th Street NE Area Flooding – Phase 1
particulars in which the final inspection reveals the work incomplete or unacceptable. The
Contractor shall immediately take such corrective measures as are necessary to remedy the
listed deficiencies. Corrective work shall be pursued vigorously, diligently, and without
interruption until physical completion of the listed deficiencies. This process will continue
until the Engineer is satisfied the listed deficiencies have been corrected.
If action to correct the listed deficiencies is not initiated within 7 days after receipt of the
written notice listing the deficiencies, the Engineer may, upon written notice to the
Contractor, take whatever steps are necessary to correct those deficiencies pursuant to
Section 1-05.7. The Contractor will not be allowed an extension of contract time because of
a delay in the performance of the work attributable to the exercise of the Engineer’s right
hereunder.
Upon correction of all deficiencies, the Engineer will notify the Contractor and the
Contracting Agency, in writing, of the date upon which the work was considered physically
complete. That date shall constitute the Physical Completion Date of the contract, but shall
not imply acceptance of the work or that all the obligations of the Contractor under the
contract have been fulfilled.
1-05.11(3) OPERATIONAL TESTING
(October 1, 2005 APWA GSP)
It is the intent of the Contracting Agency to have, at the Physical Completion Date, a
complete and operable system. Therefore when the work involves the installation of
machinery or other mechanical equipment; street lighting, electrical distribution or signal
systems; irrigation systems; buildings; or other similar work, it may be desirable for the
Engineer to have the Contractor operate and test the work for a period of time after final
inspection but prior to the physical completion date. Whenever items of work are listed in
the Contract Provisions for operational testing, they shall be fully tested under operating
conditions for the time period specified to ensure their acceptability prior to the Physical
Completion Date. During and following the test period, the Contractor shall correct any
items of workmanship, materials, or equipment which prove faulty, or that are not in first
class operating condition. Equipment, electrical controls, meters, or other devices and
equipment to be tested during this period shall be tested under the observation of the
Engineer, so the Engineer may determine their suitability for the purpose for which they
were installed. The Physical Completion Date cannot be established until testing and
corrections have been completed to the satisfaction of the Engineer.
The costs for power, gas, labor, material, supplies, and everything else needed to
successfully complete operational testing, shall be included in the unit contract prices related
to the system being tested, unless specifically set forth otherwise in the proposal.
Operational and test periods, when required by the Engineer, shall not affect a
manufacturer’s guaranties or warranties furnished under the terms of the contract.

1.0 Introduction
This Stormwater Pollution Prevention Plan (SWPPP) has been prepared as part of the NPDES
stormwater permit requirements for the 30th Street NE Area Flooding – Phase 1 construction
project situated in the SW and SE quarters of Section 06, Township 21 North, Range 5 East,
W.M., in Auburn, Washington. The site is located northeast of the interchange for State Route
167 and State Route 18. The existing site is roughly 4.4 acres, of which approximately 3 acres
are existing Right-of-Way along 30th Street NE, Auburn Way N, and I Street NE. The remaining
site area consists of a private driveway and approximately 1.2 acres of lawn along the north side
of Brannan Park. The proposed development consists of replacing approximately 4,000 linear
feet of existing 30-inch diameter storm sewer trunk line with a new 42-inch diameter pipe.
Construction activities will include asphalt concrete and cement concrete pavement removal,
excavation, backfilling, relocation of existing utility services, pipe and drainage structure
installation, pavement and sidewalk restoration, and landscape restoration.
The purpose of this SWPPP is to describe the proposed construction activities and all temporary
and permanent erosion and sediment control (TESC) measures, pollution prevention measures,
inspection/monitoring activities, and recordkeeping that will be implemented during the
proposed construction project. The objectives of the SWPPP are to:
1. Implement Best Management Practices (BMPs) to prevent erosion and
sedimentation, and to identify, reduce, eliminate or prevent stormwater
contamination and water pollution from construction activity.
2. Prevent violations of surface water quality, ground water quality, or
sediment management standards.
3. Prevent, during the construction phase, adverse water quality impacts
including impacts on beneficial uses of the receiving water by controlling
peak flow rates and volumes of stormwater runoff at the Permittee’s
outfalls and downstream of the outfalls.
This SWPPP was prepared using the Ecology SWPPP Template downloaded from the Ecology
website on October 15, 2013. This SWPPP was prepared based on the requirements set forth in
the Construction Stormwater General Permit, Stormwater Management Manual for Western
Washington (SWMMWW 2005). The report is divided into seven main sections with several
appendices that include stormwater related reference materials. The topics presented in the each
of the main sections are:
Section 1 – INTRODUCTION. This section provides a summary
description of the project, and the organization of the SWPPP document.

Section 2 – SITE DESCRIPTION. This section provides a detailed
description of the existing site conditions, proposed construction activities,
and calculated stormwater flow rates for existing conditions and post–
construction conditions.
Section 3 – CONSTRUCTION BMPs. This section provides a detailed
description of the BMPs to be implemented based on the 12 required
elements of the SWPPP (SWMMEW 2004).
Section 4 – CONSTRUCTION PHASING AND BMP
IMPLEMENTATION. This section provides a description of the timing
of the BMP implementation in relation to the project schedule.
Section 5 – POLLUTION PREVENTION TEAM. This section identifies
the appropriate contact names (emergency and non-emergency),
monitoring personnel, and the onsite temporary erosion and sedimentation
control inspector
Section 6 – INSPECTION AND MONITORING. This section provides a
description of the inspection and monitoring requirements such as the
parameters of concern to be monitored, sample locations, sample
frequencies, and sampling methods for all stormwater discharge locations
from the site.

2.0 Site Description
2.1 Existing Conditions
The proposed site is located along 30th Street NE from approximately C Street NE to Brannan
Park, situated in the SW and SE quarters of Section 06, Township 21 North, Range 5 East,
W.M., in Auburn, Washington. A site vicinity map and coordinates are provided in Appendix A.
The site is roughly 4.4 acres in size and includes portions of 30th Street NE, C Street NE, Auburn
Way N, I Street NE, a private driveway, and Brannan Park. The topography of the site and
surrounding properties are relatively flat. Subsurface soil mainly consists of alluvial deposits
ranging from silt to sand with varying amounts of gravel. Groundwater is expected to be
approximately 5 feet below the surface during the winter and spring months.
Roadway runoff is currently collected by catch basins on either side of the road and conveyed
east in the existing 30-inch diameter storm drain system to the Brannan Park Pump Station prior
to discharging to the Green River. At the point of discharge, the Green River is not included in
the Section 303(d) list under the State’s Clean Water Act. Roughly 3 miles downstream from the
point of discharge, The Green River is listed as a Category 5 polluted water of the state under the
State’s Clean Water Act Section 303(d) list, due to dissolved oxygen.
There are no critical areas on the site such as high erosion risk areas, wetlands, streams, or steep
slopes (potential landslide area). The Green River is located approximately 100 feet east of the
project limits.
2.2 Proposed Construction Activities
The north central area of Auburn has history of surface flooding with significant flooding
occurring about once every few years. The flooding along 30th Street NE was high enough to
overtop the sidewalk and inundated the immediate vicinity. In addition, the existing 30-inch
gravity storm drain that runs eastward along 30th Street NE to the Brannan Park Pump Station
does not have sufficient capacity and surcharges frequently.
The proposed flooding reduction improvement includes replacement of existing 30-inch diameter
storm sewer trunk line with new 42-inch diameter. Portions of the existing storm sewer system
will either be reconnected to the new system, be removed, or filled with CDF and abandoned in
place. Other existing underground utilities will be relocated, abandoned, or removed as necessary
to accommodate the new improvements.
Stormwater Pollution Prevention Plan

Construction activities will include asphalt concrete and cement concrete pavement removal,
excavation, backfilling, relocation of existing utility services, pipe and drainage structure
installation, pavement and sidewalk restoration, and landscape restoration. The schedule and
phasing of BMPs during construction is provided in Section 4.0.
When underground activities are completed the site will be restored to existing conditions.
Roadway, asphalt path, driveway, curb, gutter and sidewalk will be restored. Landscape areas
will receive bark mulch or sod installation.
The following summarizes details regarding site areas:
Total site area: 4.4 acres
Percent impervious area before construction: 70 %
Percent impervious area after construction: 70 %
Disturbed area during construction: 1.5 acres
Disturbed area that is characterized as impervious (i.e.,
access roads, staging, parking): 1.3 acres
2-year stormwater runoff peak flow prior to construction
(existing): 1.58 cfs
10-year stormwater runoff peak flow prior to construction
(existing): 2.74 cfs
2-year stormwater runoff peak flow during construction: 1.58 cfs
10-year stormwater runoff peak flow during construction: 2.74 cfs
2-year stormwater runoff peak flow after construction: 1.58 cfs
10-year stormwater runoff peak flow after construction: 2.74 cfs
All stormwater flow calculations are provided in Appendix F.

3.0 Construction Stormwater BMPs
3.1 The 12 BMP Elements
3.1.1 Element #1 – Mark Clearing Limits
To protect adjacent properties and to reduce the area of soil exposed to construction, the limits of
construction will be clearly marked before land-disturbing activities begin. Trees that are to be
preserved, as well as all sensitive areas and their buffers, shall be clearly delineated, both in the
field and on the plans. In general, natural vegetation and native topsoil shall be retained in an
undisturbed state to the maximum extent possible. The BMPs relevant to marking the clearing
limits that will be applied for this project include:
Preserving Natural Vegetation (BMP C101)
High Visibility Plastic or Metal Fence (BMP C103)
Natural vegetation will be preserved in areas that will not be impacted by excavation.
High visibility plastic or metal fencing will be installed along project clearing limits and to
denote the project work area within Brannan Park. The fencing will be installed prior to site
disturbance.
Alternate construction access BMPs are included in Appendix C as a quick reference tool for the
onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate
during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix
D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the
NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and
Sediment Control Lead will promptly initiate the implementation of one or more of the
alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or
failing.
3.1.2 Element #2 – Establish Construction Access
Construction access or activities occurring on unpaved areas shall be minimized, yet where
necessary, access points shall be stabilized to minimize the tracking of sediment onto public
roads, and wheel washing, street sweeping, and street cleaning shall be employed to prevent
sediment from entering state waters. All wash wastewater shall be controlled on site. The
specific BMPs related to establishing construction access that will be used on this project
include:
• No BMPs to be implemented
Stormwater Pollution Prevention Plan
6
The majority of the work will be within existing paved roadway, thus, the existing roadway
system will be utilized as construction access. Work within Brannan Park is minimized by
limiting construction activities to those associated with the utility improvements. The existing
paved and gravel access road/trail will be utilized as construction access.
Alternate construction access BMPs are included in Appendix C as a quick reference tool for the
onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate
during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix
D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the
NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and
Sediment Control Lead will promptly initiate the implementation of one or more of the
alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or
failing.
3.1.3 Element #3 – Control Flow Rates
In order to protect the properties and waterways downstream of the project site, stormwater
discharges from the site will be controlled. The specific BMPs for flow control that shall be used
on this project include:
• No BMPs to be implemented
During construction, stormwater will be collected by existing catch basins and routed through the
existing storm sewer system and/or temporary by-pass system until the new storm sewer trunk
line has been installed and activated. The project will not increase impervious areas.
Alternate flow control BMPs are included in Appendix C as a quick reference tool for the onsite
inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate during
construction to satisfy the requirements set forth in the General NPDES Permit (Appendix D).
To avoid potential erosion and sediment control issues that may cause a violation(s) of the
NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and
Sediment Control Lead will promptly initiate the implementation of one or more of the
alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or
failing.
The project site is located west of the Cascade Mountain Crest. As such, the project must
comply with Minimum Requirement 7 (Ecology 2005).
In general, discharge rates of stormwater from the site will be controlled where increases in
impervious area or soil compaction during construction could lead to downstream erosion, or
where necessary to meet local agency stormwater discharge requirements (e.g. discharge to
combined sewer systems).
Stormwater Pollution Prevention Plan

3.1.4 Element #4 – Install Sediment Controls
All stormwater runoff from disturbed areas shall pass through an appropriate sediment removal
BMP before leaving the construction site or prior to being discharged to an infiltration facility.
The specific BMPs to be used for controlling sediment on this project include:
• Silt Fence (BMP C233)
• Straw Wattles (BMP C235)
• Storm Drain Inlet Protection (BMP C220)
Silt fence will be installed where overland flow will travel outside the project work area. Silt
fence will be installed prior to construction activities.
Straw wattles will be installed where overland flow will travel outside the project work area and
it is impractical to install silt fence. Straw wattles will be installed prior to construction
activities.
Storm drain inlet protection will be installed on any catch basins that may receive sediment laden
runoff from the project site. Storm drain inlet protection will be installed prior to any site
activity that may result in sediment laden runoff.
Alternate sediment control BMPs are included in Appendix C as a quick reference tool for the
onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate
during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix
D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the
NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and
Sediment Control Lead will promptly initiate the implementation of one or more of the
alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or
failing.
In addition, sediment will be removed from paved areas in and adjacent to construction work
areas manually or using mechanical sweepers, as needed, to minimize tracking of sediments on
vehicle tires away from the site and to minimize washoff of sediments from adjacent streets in
runoff.
Whenever possible, sediment laden water shall be discharged into onsite, relatively level,
vegetated areas (BMP C240 paragraph 5, page 4-102).
In some cases, sediment discharge in concentrated runoff can be controlled using permanent
stormwater BMPs (e.g., infiltration swales, ponds, trenches). Sediment loads can limit the
effectiveness of some permanent stormwater BMPs, such as those used for infiltration or
biofiltration; however, those BMPs designed to remove solids by settling (wet ponds or detention
ponds) can be used during the construction phase. When permanent stormwater BMPs will be
Stormwater Pollution Prevention Plan
8
used to control sediment discharge during construction, the structure will be protected from
excessive sedimentation with adequate erosion and sediment control BMPs. Any accumulated
sediment shall be removed after construction is complete and the permanent stormwater BMP
will be restabilized with vegetation per applicable design requirements once the remainder of the
site has been stabilized.
The following BMPs will be implemented as end-of-pipe sediment controls as required to meet
permitted turbidity limits in the site discharge(s). Prior to the implementation of these
technologies, sediment sources and erosion control and soil stabilization BMP efforts will be
maximized to reduce the need for end-of-pipe sedimentation controls.
Temporary Sediment Pond (BMP C241)
Construction Stormwater Filtration (BMP C251)
Construction Stormwater Chemical Treatment (BMP C 250)
(implemented only with prior written approval from Ecology).
3.1.5 Element #5 – Stabilize Soils
Exposed and unworked soils shall be stabilized with the application of effective BMPs to prevent
erosion throughout the life of the project. The specific BMPs for soil stabilization that shall be
used on this project include:
• Plastic Covering (BMP C123)
• Dust Control (BMP C140)
Plastic covering shall be kept on hand by the Contractor to provide short-term erosion protection
to disturbed areas as necessary.
Dust control will be implemented by the Contractor as necessary to prevent wind transport of
dust from disturbed soil surfaces for the duration of construction.
Alternate soil stabilization BMPs are included in Appendix C as a quick reference tool for the
onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate
during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix
D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the
NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and
Sediment Control Lead will promptly initiate the implementation of one or more of the
alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or
failing.
Stormwater Pollution Prevention Plan

The project site is located west of the Cascade Mountain Crest. As such, no soils shall remain
exposed and unworked for more than 7 days during the dry season (May 1 to September 30) and
2 days during the wet season (October 1 to April 30). Regardless of the time of year, all soils
shall be stabilized at the end of the shift before a holiday or weekend if needed based on weather
forecasts.
In general, cut and fill slopes will be stabilized as soon as possible and soil stockpiles will be
temporarily covered with plastic sheeting. All stockpiled soils shall be stabilized from erosion,
protected with sediment trapping measures, and where possible, be located away from storm
drain inlets, waterways, and drainage channels.
3.1.6 Element #6 – Protect Slopes
All cut and fill slopes will be designed, constructed, and protected in a manner than minimizes
erosion. The following specific BMPs will be used to protect slopes for this project:
• No BMPs to be implemented
The project site is relatively flat and there are no steep slopes to protect.
Alternate slope protection BMPs are included in Appendix C as a quick reference tool for the
onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate
during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix
D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the
NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and
Sediment Control Lead will promptly initiate the implementation of one or more of the
alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or
failing.
3.1.7 Element #7 – Protect Drain Inlets
All storm drain inlets and culverts made operable during construction shall be protected to
prevent unfiltered or untreated water from entering the drainage conveyance system. However,
the first priority is to keep all access roads clean of sediment and keep street wash water separate
from entering storm drains until treatment can be provided. Storm Drain Inlet Protection (BMP
C220) will be implemented for all drainage inlets and culverts that could potentially be impacted
by sediment-laden runoff on and near the project site. The following inlet protection measures
will be applied on this project:
Drop Inlet Protection
• Catch Basin Filters
Stormwater Pollution Prevention Plan
10
If the BMP options listed above are deemed ineffective or inappropriate during construction to
satisfy the requirements set forth in the General NPDES Permit (Appendix D), or if no BMPs are
listed above but deemed necessary during construction, the Certified Erosion and Sediment
Control Lead shall implement one or more of the alternative BMP inlet protection options listed
in Appendix C.
3.1.8 Element #8 – Stabilize Channels and Outlets
Where site runoff is to be conveyed in channels, or discharged to a stream or some other natural
drainage point, efforts will be taken to prevent downstream erosion. The specific BMPs for
channel and outlet stabilization that shall be used on this project include:
No BMPs to be implemented
During construction, site runoff will be collected and conveyed through the existing storm sewer
system to the Brannan Park Pump Station. Existing outfall will be maintained and utilized.
Alternate channel and outlet stabilization BMPs are included in Appendix C as a quick reference
tool for the onsite inspector in the event the BMP(s) listed above are deemed ineffective or
inappropriate during construction to satisfy the requirements set forth in the General NPDES
Permit (Appendix D). To avoid potential erosion and sediment control issues that may cause a
violation(s) of the NPDES Construction Stormwater permit (as provided in Appendix D), the
Certified Erosion and Sediment Control Lead will promptly initiate the implementation of one or
more of the alternative BMPs listed in Appendix C after the first sign that existing BMPs are
ineffective or failing.
The project site is located west of the Cascade Mountain Crest. As such, all temporary on-site
conveyance channels shall be designed, constructed, and stabilized to prevent erosion from the
expected peak 10 minute velocity of flow from a Type 1A, 10-year, 24-hour recurrence interval
storm for the developed condition. Alternatively, the 10-year, 1-hour peak flow rate indicated by
an approved continuous runoff simulation model, increased by a factor of 1.6, shall be used.
Stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent
streambanks, slopes, and downstream reaches shall be provided at the outlets of all conveyance
systems.
3.1.9 Element #9 – Control Pollutants
All pollutants, including waste materials and demolition debris, that occur onsite shall be
handled and disposed of in a manner that does not cause contamination of stormwater. Good
housekeeping and preventative measures will be taken to ensure that the site will be kept clean,
well organized, and free of debris. If required, BMPs to be implemented to control specific
sources of pollutants are discussed below.
Stormwater Pollution Prevention Plan
11
The facility is transportation-related and therefore not subject to the Federal requirements of the
Spill Prevention, Control, and Countermeasure (SPCC) Plan under the Clean Water Act (CWA).
If applicable, the Contractor shall prepare an SPCC Plan according to the Washington State
Department of Transportation (WSDOT) Requirements (see the WSDOT Standard Specifications
for Road, Bridge, and Municipal Construction 2004).
The facility does not require a Spill Prevention, Control, and Countermeasure (SPCC) Plan under
the Federal regulations of the Clean Water Act (CWA).
3.1.10 Element #10 – Control Dewatering
All dewatering water from open cut excavation, tunneling, foundation work, trench, or
underground vaults shall be discharged into a controlled conveyance system prior to discharge to
a sediment trap or sediment pond. Channels will be stabilized, per Element #8. Clean, non-
turbid dewatering water will not be routed through stormwater sediment ponds, and will be
discharged to systems tributary to the receiving waters of the State in a manner that does not
cause erosion, flooding, or a violation of State water quality standards in the receiving water.
Highly turbid dewatering water from soils known or suspected to be contaminated, or from use
of construction equipment, will require additional monitoring and treatment as required for the
specific pollutants based on the receiving waters into which the discharge is occurring. Such
monitoring is the responsibility of the contractor.
However, the dewatering of soils known to be free of contamination will trigger BMPs to trap
sediment and reduce turbidity. At a minimum, geotextile fabric socks/bags/cells will be used to
filter this material. Other BMPs to be used for sediment trapping and turbidity reduction include
the following:
Portable Water Storage Tanks (e.g. Baker Tank) for Sedimentation
Construction Stormwater Filtration (BMP C 251)
This site has high groundwater and will require trench dewatering to install the new storm sewer
improvements. Dewatering discharge will be filtered to remove suspended solids and sediment
prior to release from the site.
Alternate dewatering control BMPs are included in Appendix C as a quick reference tool for the
onsite inspector in the event the BMP(s) listed above are deemed ineffective or inappropriate
during construction to satisfy the requirements set forth in the General NPDES Permit (Appendix
D). To avoid potential erosion and sediment control issues that may cause a violation(s) of the
NPDES Construction Stormwater permit (as provided in Appendix D), the Certified Erosion and
Sediment Control Lead will promptly initiate the implementation of one or more of the
alternative BMPs listed in Appendix C after the first sign that existing BMPs are ineffective or
failing.
Stormwater Pollution Prevention Plan
12
3.1.11 Element #11 – Maintain BMPs
All temporary and permanent erosion and sediment control BMPs shall be maintained and
repaired as needed to assure continued performance of their intended function. Maintenance and
repair shall be conducted in accordance with each particular BMP’s specifications. Visual
monitoring of the BMPs will be conducted at least once every calendar week and within 24 hours
of any rainfall event that causes a discharge from the site. If the site becomes inactive, and is
temporarily stabilized, the inspection frequency will be reduced to once every month.
All temporary erosion and sediment control BMPs shall be removed within 30 days after the
final site stabilization is achieved or after the temporary BMPs are no longer needed. Trapped
sediment shall be removed or stabilized on site. Disturbed soil resulting from removal of BMPs
or vegetation shall be permanently stabilized.
3.1.12 Element #12 – Manage the Project
Erosion and sediment control BMPs for this project have been designed based on the following
principles:
Design the project to fit the existing topography, soils, and drainage
patterns.
Emphasize erosion control rather than sediment control.
Minimize the extent and duration of the area exposed.
Keep runoff velocities low.
Retain sediment on site.
Thoroughly monitor site and maintain all ESC measures.
Schedule major earthwork during the dry season.
In addition, project management will incorporate the key components listed below:
As this project site is located west of the Cascade Mountain Crest, the project will be managed
according to the following key project components:
Phasing of Construction
The construction project is being phased to the extent practicable in order
to prevent soil erosion, and, to the maximum extent possible, the transport
of sediment from the site during construction.
Stormwater Pollution Prevention Plan
13
Revegetation of exposed areas and maintenance of that vegetation shall be
an integral part of the clearing activities during each phase of construction,
per the Scheduling BMP (C 162).
Seasonal Work Limitations
From October 1 through April 30, clearing, grading, and other soil
disturbing activities shall only be permitted if shown to the satisfaction of
the local permitting authority that silt-laden runoff will be prevented from
leaving the site through a combination of the following:
Site conditions including existing vegetative coverage, slope, soil
type, and proximity to receiving waters; and
Limitations on activities and the extent of disturbed areas; and
Proposed erosion and sediment control measures.
Based on the information provided and/or local weather conditions, the
local permitting authority may expand or restrict the seasonal limitation on
site disturbance.
The following activities are exempt from the seasonal clearing and grading
limitations:
Routine maintenance and necessary repair of erosion and sediment
control BMPs;
Routine maintenance of public facilities or existing utility
structures that do not expose the soil or result in the removal of the
vegetative cover to soil; and
Activities where there is 100 percent infiltration of surface water
runoff within the site in approved and installed erosion and
sediment control facilities.
Coordination with Utilities and Other Jurisdictions

Inspection and Monitoring
All BMPs shall be inspected, maintained, and repaired as needed to assure
continued performance of their intended function. Site inspections shall
be conducted by a person who is knowledgeable in the principles and
practices of erosion and sediment control. This person has the necessary
skills to:
Assess the site conditions and construction activities that could
impact the quality of stormwater, and
Assess the effectiveness of erosion and sediment control measures
used to control the quality of stormwater discharges.
A Certified Erosion and Sediment Control Lead shall be on-site or on-call
at all times.
Whenever inspection and/or monitoring reveals that the BMPs identified
in this SWPPP are inadequate, due to the actual discharge of or potential
to discharge a significant amount of any pollutant, appropriate BMPs or
design changes shall be implemented as soon as possible.
Maintaining an Updated Construction SWPPP
This SWPPP shall be retained on-site or within reasonable access to the
site.
The SWPPP shall be modified whenever there is a change in the design,
construction, operation, or maintenance at the construction site that has, or
could have, a significant effect on the discharge of pollutants to waters of
the state.
The SWPPP shall be modified if, during inspections or investigations
conducted by the owner/operator, or the applicable local or state
regulatory authority, it is determined that the SWPPP is ineffective in
eliminating or significantly minimizing pollutants in stormwater
discharges from the site. The SWPPP shall be modified as necessary to
include additional or modified BMPs designed to correct problems
identified. Revisions to the SWPPP shall be completed within seven (7)
days following the inspection.

6.0 Site Inspections and Monitoring
Monitoring includes visual inspection, monitoring for water quality parameters of concern, and
documentation of the inspection and monitoring findings in a site log book. A site log book will
be maintained for all on-site construction activities and will include:
A record of the implementation of the SWPPP and other permit
requirements;
Site inspections; and,
Stormwater quality monitoring.
For convenience, the inspection form and water quality monitoring forms included in this
SWPPP include the required information for the site log book. This SWPPP may function as the
site log book if desired, or the forms may be separated and included in a separate site log book.
However, if separated, the site log book but must be maintained on-site or within reasonable
access to the site and be made available upon request to Ecology or the local jurisdiction.
6.1 Site Inspection
All BMPs will be inspected, maintained, and repaired as needed to assure continued performance
of their intended function. The inspector will be a Certified Erosion and Sediment Control Lead
(CESCL) per BMP C160. The name and contact information for the CESCL is provided in
Section 5 of this SWPPP.
Site inspection will occur in all areas disturbed by construction activities and at all stormwater
discharge points. Stormwater will be examined for the presence of suspended sediment,
turbidity, discoloration, and oily sheen. The site inspector will evaluate and document the
effectiveness of the installed BMPs and determine if it is necessary to repair or replace any of the
BMPs to improve the quality of stormwater discharges. All maintenance and repairs will be
documented in the site log book or forms provided in this document. All new BMPs or design
changes will be documented in the SWPPP as soon as possible.
6.1.1 Site Inspection Frequency
Site inspections will be conducted at least once a week and within 24 hours following any
discharge from the site. For sites with temporary stabilization measures, the site inspection
frequency can be reduced to once every month.
Stormwater Pollution Prevention Plan
20
6.1.2 Site Inspection Documentation
The site inspector will record each site inspection using the site log inspection forms provided in
Appendix E. The site inspection log forms may be separated from this SWPPP document, but
will be maintained on-site or within reasonable access to the site and be made available upon
request to Ecology or the local jurisdiction.
6.2 Stormwater Quality Monitoring
6.2.1 Turbidity Sampling
Monitoring requirements for the proposed project will include either turbidity or water
transparency sampling to monitor site discharges for water quality compliance with the 2005
Construction Stormwater General Permit (Appendix D). Sampling will be conducted at all
discharge points at least once per calendar week.
Turbidity or transparency monitoring will follow the analytical methodologies described in
Section S4 of the 2005 Construction Stormwater General Permit (Appendix D). The key
benchmark values that require action are 25 NTU for turbidity (equivalent to 32 cm
transparency) and 250 NTU for turbidity (equivalent to 6 cm transparency). If the 25 NTU
benchmark for turbidity (equivalent to 32 cm transparency) is exceeded, the following steps will
be conducted:
1. Ensure all BMPs specified in this SWPPP are installed and functioning as
intended.
2. Assess whether additional BMPs should be implemented, and document
revisions to the SWPPP as necessary.
3. Sample discharge location daily until the analysis results are less than 25
NTU (turbidity) or greater than 32 cm (transparency).
If the turbidity is greater than 25 NTU (or transparency is less than 32 cm) but less than 250
NTU (transparency greater than 6 cm) for more than 3 days, additional treatment BMPs will be
implemented within 24 hours of the third consecutive sample that exceeded the benchmark
value. Additional treatment BMPs to be considered will include, but are not limited to, off-site
treatment, infiltration, filtration and chemical treatment.
If the 250 NTU benchmark for turbidity (or less than 6 cm transparency) is exceeded at any time,
the following steps will be conducted:
1. Notify Ecology by phone within 24 hours of analysis (see Section 5.0 of
this SWPPP for contact information).
Stormwater Pollution Prevention Plan
21
2. Continue daily sampling until the turbidity is less than 25 NTU (or
transparency is greater than 32 cm).
3. Initiate additional treatment BMPs such as off-site treatment, infiltration,
filtration and chemical treatment within 24 hours of the first 250 NTU
exceedance.
4. Implement additional treatment BMPs as soon as possible, but within 7
days of the first 250 NTU exceedance.
5. Describe inspection results and remedial actions taken in the site log book
and in monthly discharge monitoring reports as described in Section 7.0 of
this SWPPP.
Stormwater Pollution Prevention Plan
23
7.0 Reporting and Recordkeeping

7.1.4 Updating the SWPPP
In accordance with Conditions S3, S4.B, and S9.B.3 of the General Permit, this SWPPP will be
modified if the SWPPP is ineffective in eliminating or significantly minimizing pollutants in
stormwater discharges from the site or there has been a change in design, construction, operation,
or maintenance at the site that has a significant effect on the discharge, or potential for discharge,
of pollutants to the waters of the State. The SWPPP will be modified within seven days of
determination based on inspection(s) that additional or modified BMPs are necessary to correct
problems identified, and an updated timeline for BMP implementation will be prepared.
7.2 Reporting
7.2.1 Discharge Monitoring Reports
[Prior to October 2008] If cumulative soil disturbance is smaller than 5 acres: Discharge
Monitoring Report (DMR) forms will not be submitted to Ecology because water quality
sampling is not being conducted at the site.
If cumulative soil disturbance is 5 acres or larger: Discharge Monitoring Reports (DMRs) will be
submitted to Ecology monthly. If there was no discharge during a given monitoring period, the
Permittee shall submit the form as required, with the words “No discharge” entered in the place
of monitoring results. The DMR due date is 15 days following the end of each month.
7.2.2 Notification of Noncompliance
If any of the terms and conditions of the permit are not met, and it causes a threat to human
health or the environment, the following steps will be taken in accordance with permit section
S5.F:
1. Ecology will be immediately notified of the failure to comply.
2. Immediate action will be taken to control the noncompliance issue and to
correct the problem. If applicable, sampling and analysis of any
noncompliance will be repeated immediately and the results submitted to
Ecology within five (5) days of becoming aware of the violation.
3. A detailed written report describing the noncompliance will be submitted
to Ecology within five (5) days, unless requested earlier by Ecology.
