i. Brief summary of the treatment alternatives considered and why the proposed
option was selected. Include cost estimates of ongoing operation and
maintenance, including disposal of any spent media
Estes Express Lines (Estes) considered a variety of treatment alternatives that would
produce benchmark water quality in future site stormwater discharges. Advanced
GeoEnvironmental, Inc. (AGE) has served as the environmental consultant for Estes and
provided the basis for the treatment selection to StormwateRx for this report. The
alternatives considered include onsite infiltration, above-grade and below-grade filtrations
systems, electrocoagulation (EC) and chitosan enhanced sand filtration (CESF).
Infiltration was eliminated as a viable option because the space required would
significantly disrupt primary operations, and because the facility is directly on the roadway.
Estes and AGE evaluated a below-grade flow-through StormFilter design by Contech.
However, it was determined that the StormFilter treatment technology would not be
suitable for the facility, as it would disrupt a large amount of site operational area, primarily
due to the detention storage requirements. Because of the nature of operations at Estes,
available space is a critically important consideration. The StormFilter system has
recieved TAPE approval for basic treatment, but not for enhanced treatment, and
investigative sampling has indicated that zinc in the facility’s stormwater is 30%-50%
dissolved. Therefore, a treatment system with enhanced approval was preferred.
Additionally, the drainage system on the Estes facility cannot generate a sufficient drop in
slope to have a dependable drain to the outfall, using a Contech flow-through StormFilter
design.
EC and CESF systems were eliminated as options because they each require ongoing
operating contracts with each vendor due to the complexity of these active systems that
need to be managed. Such operating contracts present an additional ongoing cost of
operation of these systems, and reduce the cost-effectiveness over the system's lifetime.
The estimated capital and maintenance costs for EC and CESF systems were not
provided to StormwateRx.
The selected treatment alternative is the StormwateRx Aquip enhanced stormwater
filtration system. This system can be installed onsite and integrated with the existing site
stormwater infrastructure without substantially affecting normal facility operations. The
characteristic treatment performance of the Aquip filter technology for metals and turbidity
at a variety of similar industrial applications indicates that treated discharge from the Aquip
filter will satisfy benchmark water quality. The Aquip filter is described in greater detail in
section iii.
Typical filter maintenance for the proposed Aquip enhanced stormwater filtration
technology is described in three categories: routine maintenance, seasonal maintenance,
or full maintenance. Routine maintenance refers to the regular cleaning of the filter media
surface to remove accumulated sediment and occluded media in order to maintain flow
capacity of the filter; a topper media supply is added after multiple instances of routine
maintenance in order to return the filter media depth to original conditions. Seasonal
maintenance refers to the removal and replacement of the upper inert layers of filter media
3
StormwateRx, LLC
Level 3 Corrective Action Engineering Report
Estes Express Lines
when sufficient sediment has accumulated within the bed and routine maintenance can
no longer restore flow capacity of the filter. Full maintenance refers to the removal and
replacement of the full media bed to restore the filter to original conditions when the flow
capacity or treatment performance is suffering due to accumulated sediment load in the
lower sorptive media layers. Spent media is not characterized as hazardous material and
can be disposed of in a subtitle D landfill. An analysis of expected maintenance costs and
frequencies for the proposed system is presented in Table 1.

ii. The basic design data, including characterization of stormwater influent, and
sizing calculations of the treatment units
The site operates under the NPDES Industrial Stormwater General Permit (permit number
WAR008739), effective as of January 2, 2015. This permit sets water quality standards
for stormwater discharges to surface waters or storm sewers that drain to surface waters.
The water quality parameters of concern at Estes are turbidity, copper, and zinc. Estes
will implement additional treatment BMPs onsite to address water quality exceedances.
Existing Conditions:
Estes is located at 2102 West Valley Highway North in Auburn, WA. The facility is
approximately 5.9 acres, with 4.9 acres of paved surface, 0.81 acres of building rooftops,
and 0.16 acres of vegetated area.
The Estes facility is a single drainage basin with an outfall to the City of Auburn municipal
storm drain on West Valley Highway N. This outfall is called Outfall 1 in the facility’s
Stormwater Pollution Prevention Plan (SWPPP, see Appendix A). Stormwater runoff
generated onsite flows to a series of catch basins and is conveyed through underground
4
StormwateRx, LLC
Level 3 Corrective Action Engineering Report
Estes Express Lines
storm drain lines to CB1, a catch basin vault that serves as the monitoring point for the
facility and discharges to the outfall.
Estes uses a set of structural and treatment BMPs on site to control the quality of
stormwater runoff. These BMPs are described in the facility’s SWPPP and include catch
basin inserts installed in 2016, and downspout filters installed in 2017. These structural
BMPs were intended to reduce turbidity and metals in the site stormwater discharge.
Proposed Conditions
Estes will upgrade its existing stormwater treatment BMPs with the installation of a
StormwateRx Aquip® 300SBE enhanced stormwater filtration system to address turbidity
and zinc in stormwater discharges. The existing CB1 catch basin and vault will be modified
to serve as a deeper structure to accommodate a treatment pump. The existing site
drainage flow pattern will be maintained, and the treatment pump will receive flows from
the entire site. The treatment pump will supply untreated stormwater to the Aquip filter at
a rate of 235 gpm, corresponding to the water quality design flow rate for the site as
determined using the Western Washington Hydrology Model (WWHM2012, v.4.2.12, see
Appendix B). Treated Aquip discharge will return by gravity to the discharge point of CB1
and continue to the outfall. Runoff flows in excess of the water quality design flowrate will
bypass the Aquip and be discharged to the outfall.
In addition to the proposed treatment BMP, Estes will also make improvements to pollutant
source control. A new sweeping protocol scope is to be implemented with the relocation
of the cargo trailers during cleaning, as much as possible. Utilizing brooms and pressure
washers with vacuum recovery for cleanup under parked equipment, will collect
recalcitrant sources of pollution. Focused cleaning on areas not maintained by standard
Truck sweeping services will be conducted under trailers and near the dock area. The
standard truck-based sweeping services will be conducted, on a minimum monthly basis.
Characterization of Stormwater Influent
The proposed stormwater treatment system will be incorporated into the existing site
stormwater infrastructure at a point just prior to site discharge. The characteristic water
quality of the influent to the proposed Aquip treatment system can therefore be
represented by historic site discharges. Historic site discharge monitoring results for 2016
and 2017 are shown in Table 2 (quarterly averages shown).

Stormwater Treatment Sizing
The water quality (WQ) design flow rate varies depending on a treatment facility’s design
and if they are categorized as an online or offline system. The online WQ design flow rate
is used when all stormwater flows through a treatment device. The offline flow rate is used
when a high flow bypass (flow splitting device) is present, and flow rates which exceed the
WQ design flow rate are bypassed. The stormwater treatment system proposed for this
site is designed with a bypass system and is sized to handle the offline WQ design flow
rate. Only water which exceeds the WQ design flow rate will bypass the stormwater
treatment system.
Per Volume 5, Section 4.1.2 of the Stormwater Management Manual for Western
Washington (SWMMWW), offline WQ design flow rate was calculated using an approved
continuous runoff model, the Western Washington Hydrology Model (WWHM2012,
v.4.2.12). The facility was modeled using 5.71 acres of impervious industrial area,
classified as flat impervious land use. Additional model details can be found in the model
output report in Appendix B. The WQ design flow rate generated by the model is 235 gpm
for the facility, corresponding to the “off-line BMP, 15-minute” flow rate.
StormwateRx has established a set of operational and design criteria for the Aquip that
has been applied to other facilities in Washington. The proposed treatment filters will use
the Ecology CULD approved Aquip enhanced stormwater filtration system media
configuration and a surface loading rate not to exceed 1 gpm/sf. The WWHM was used to
establish the design flow rate as described, and the filter size was selected as the next
largest Aquip size that can process the design flow rate. This sizing approach translates
to a more conservative (environmentally protective) surface loading rate. Operating Aquip
at a lower surface loading rate than the operational criterion also extends the maintenance
interval of the system. The proposed Aquip 300SBE filter for Estes will be operating at a
surface loading rate of 0.8 gpm/sf of media surface.

iii. A description of the treatment process and operation, including a flow diagram
Under the proposed conditions, site stormwater runoff will follow existing drainage
infrastructure and conveyance, flowing to catch basin CB1 prior to discharge. Catch basin
CB1 will be retrofitted to provide a deeper sump, in order to accommodate a 235-gpm
treatment pump. Runoff flowrates that are less than or equal to 235 gpm will be pumped
from the new CB1 to the new Aquip 300SBE stormwater filter. Flows in excess of 235 gpm
will be discharged directly from the CB1 to the outfall, bypassing treatment. The existing
CB1 outlet structure will be modified to receive both treated and untreated bypass flows,
and provide an opportunity to sample the comingled discharge to the outfall. See Figure
1.
Figure 1. Estes Process Flow Diagram for the Proposed Site Improvements
A preferred location for the Aquip filter has been selected on-site to facilitate maintenance
access to the filter, minimize the potential for equipment damage, and prevent disruption
to industrial activities. A site layout drawing showing the proposed placement of the Aquip
filter and connection to CB1 is provided in Appendix C.
The Aquip is a passive adsorptive depth-filtration technology that removes industrial
stormwater pollutants such as suspended solids, turbidity, heavy metals, nutrients and
organics. Aquip is a patented system that uses a pre-treatment chamber followed by a
series of layered inert and adsorptive filtration media to effectively trap pollutants in an
above-ground, pre-configured steel structure. The pollutant removal within the pretreatment chamber occurs by gravity settling and adsorption; pollutant removal within the
filtration chamber occurs through a combination of filtration, chemical complexing, coprecipitation, adsorption, absorption, micro-sedimentation and biological oxidation. Aquip
has no moving parts and requires no chemicals, making operation inherently simple and
safe.

StormwateRx, LLC
Level 3 Corrective Action Engineering Report

The Aquip is a robust industrial stormwater treatment technology. Once polluted
stormwater is pumped into the system, stormwater flows by gravity through the structure.
A detail drawing of the model 300SBE is provided in Appendix D, and additional
operational of the Aquip system are provided in the Aquip O&M manual in Appendix E.

The Industrial Stormwater General Permit requires monitoring of turbidity, pH, oil sheen,
copper, and zinc, as well as petroleum hydrocarbons for facilities operating under SIC
code 4213. These parameters and benchmarks were considered in the design of the
treatment system proposed for the site. A summary of the parameters and benchmarks
are listed in Table 3.

Historical stormwater monitoring from the facility has indicated turbidity, copper, and zinc
to be parameters of concern.
The proposed Aquip 300SBE filter is expected to provide a level of performance that is in
line with historic performance seen in similar full-scale units installed at other industrial
facilities. StormwateRx has collected performance data in the form of inlet/outlet sample
pairs for many of the Aquip filters that have been installed and operating at other sites.
Table 4 provides a summary of all performance data used in the analysis. The median
removal efficiency for each parameter is presented in the far-right column, along with the

vi. A statement, expressing sound engineering justification through the use of pilot
plant data, results from other similar installations, and/or scientific evidence from
the literature, or both, that the proposed treatment is reasonable expected to meet
the permit benchmarks
The Aquip system is installed at numerous other facilities and has shown to provide a high
level of pollutant reduction. Using this data, StormwateRx is able to size the system for
Estes to provide optimal pollutant removal efficiencies. Based upon the findings in “Aquip
Technology Assessment”, the Aquip system has been given the Conditional Use Level
Designation in Washington by Department of Ecology for basic (TSS), enhanced
(dissolved copper and zinc), and phosphorus treatment (see Appendix F). The Aquip has
been designed to operate in conjunction with the site source control and operational
BMPs.
The Aquip filter can also be retrofitted with additional treatment if stronger performance is
required in the future. A polishing system that treats for particulate and dissolved metals
can be added and would require less space than another Aquip 300SBE filter. At the time
of this report, additional treatment is not expected to be required.

FACILITY ASSESSMENT
2.1.
FACILITY DESCRIPTION
GI Trucking Co./DBA Estes West (Estes) operates a cargo transportation and distribution
facility on approximately 6 acres of property in Auburn, Washington. Nearly all of the site
is paved or impervious, except for a landscaped area along the west side of the property.
The surface area of the entire site is 250,000 square feet.
The facility includes a 23,800 square-foot warehouse and an approximately 4,300 square
foot office. The topography of the site is generally flat with slopes of less than a degree
sloping to catch basins. The facility is in operation from 6 p.m. Sunday to 4 p.m. Saturday.
2.2.
INDUSTRIAL ACTIVITY, MATERIALS INVENTORY AND ASSOCIATED
POLLUTANTS
Industrial activities at the site include cargo loading and unloading and minor maintenance
activities. The facility receives a wide variety of containerized and bulk cargoes which
include all freight except hazardous waste, dangerous explosives, commodities of
exceptionally high value, commodities in bulk and those requiring specialized equipment.
30 March 2018
AGE Proposal No. 18-4323
Page 4 of 27
With the exception of the office building and vegetated areas, the entire site may be
associated with industrial activity including loading/unloading, cargo trailer storage and
minor maintenance activities.
Small quantities of solid wastes, used oils and lubricants, and paints are generated inside
the maintenance shop located in the north central portion of the site. These wastes are
stored inside the maintenance shop, under canopy cover, in secondary containment and
are routinely removed from the site by a licensed transporter and managed at an
appropriately permitted disposal or recycling facility. Fueling activities occur within the
loading yard, with implementation of appropriate best management practices (see
section 3), by a third-party mobile fueling truck. No waste treatment occurs on-site.
Building materials include masonry, concrete and coated sheet metal. Roofing materials
consist of coated sheet metal. There is galvanized and electrified security fencing on the
north, south, east and west boundaries of the cargo yard.
Maintenance of forklifts and other yard equipment occurs inside the maintenance shop
on the north side of the warehouse. On rare occasions, maintenance of equipment too
tall to fit inside the shop is done on the yard with implementation of appropriate best
management practices (see section 3).
There are no emissions from a manufacturing building or process area onto a roof or
other exposed surface at the facility.

SPILLS AND LEAKS
There has not been a spill at the site at any time over the past five years. However, spills
and/or leaks potentially could occur from ruptured hydraulic lines, fuel lines or other
equipment fluid in the Cargo Yard. Spills and leaks in this area could potentially impact
the drainage conveyance and Outfall 1.
Spills in the Maintenance Shop likely would be contained with spill response equipment
and prevented from exposure to stormwater. The Maintenance Shop is floor selfcontained and drains to the sanitary sewer, though a treatment device. A form used to
document significant/reportable spills and leaks is included as Appendix A. This form will
be updated as necessary.

Assign one or more individuals to be responsible for stormwater pollution control.
Hold regular meetings to review the overall operation of the BMPs. Establish
responsibilities for inspections, operation, maintenance, and for emergencies.
Train all team members in the operation, maintenance, and inspections of BMPs,
and reporting procedures.
Promptly contain and clean up spills or leaks of solid and liquid pollutants such as
oils, solvents, fuels, and dust from manufacturing operations on any exposed soil,
vegetation, or paved area.
Do not hose down pollutants from any area to the ground, storm drains,
conveyance ditches, or receiving water unless necessary for dust control
purposes to meet air quality regulations. Convey pollutants before discharge, to
a treatment system approved by the local jurisdiction.
Regularly clean oils, debris, sludge, etc. from all stormwater facilities, including
catch basins, settling/detention basins, oil/water separators, boomed areas, and
conveyance systems to prevent the contamination of stormwater. Refer to
Appendix IV-D R.3 of the Stormwater Management Manual for Western
Washington for references to assist in handling potentially dangerous waste.
Promptly repair or replace substantially cracked or otherwise damaged paved
secondary containment, high-intensity parking, or any drainage areas that may
be subjected to pollutant leaks or spills. Promptly repair or replace leaking
connections, pipes, hoses, valves, etc., which can contaminate stormwater.
Do not connect floor drains in potential pollutant source areas to storm drains, or
other conveyances that release to surface water or to the ground.
3.1.2. Mandatory BMPs – Preventative Maintenance
Clean catch basins when the depth of debris reaches 60% of the sump depth or
when the debris surface reaches 6 inches below the outlet pipe, whichever occurs
first.
Inspect all equipment and vehicles during monthly site inspections for leaking fluids
such as oil or antifreeze, etc. Take leaking equipment and vehicles out of service
and prevent leaks from spilling on the ground until repaired.
Immediately clean up spills and leaks (e.g., using absorbents, vacuuming, etc.) to
prevent the discharge of pollutants.
Maintain ponds, tanks/vaults, catch basins, swales, filters, oil/water separators,
drains and other stormwater drainage/treatment facilities in accordance with the
Maintenance Standards set forth in the applicable Stormwater Management
Manual (SWMM), other guidance documents or manuals approved in accordance

submitted to the Washington Department of Ecology (“Ecology”) in accordance
with S8.D.
Prevent the discharge of unpermitted liquid or solid wastes, process wastewater,
or sewage to ground or surface water, or to storm drains that discharge to surface
water, or to the ground. Conduct all oily parts cleaning, steam cleaning, or pressure
washing of equipment or containers inside a building, or on an impervious
contained area, such as a concrete pad. Direct contaminated stormwater from
such an area to a sanitary sewer where allowed by local sewer authority, or to
other approved treatment.
Pressure wash impervious surfaces contaminated with oils, metals, sediment, etc.,
after plugging or otherwise preventing discharge from storm drains, if any. Collect
the resulting washwater, by pumping or vactoring, for proper disposal by discharge
to sanitary sewer or via vactor (vacuum) truck transport to a wastewater treatment
plant.
Do not pave over contaminated soil unless it has been determined that ground
water has not been and will not be contaminated by the soil. Call Ecology for
assistance.
Construct impervious areas that are compatible with the materials to be handled
there. Portland cement concrete, asphalt, or equivalent materials often are suitable
materials for construction of impervious surfaces.
Use drip pans to collect leaks and spills from industrial/ commercial equipment
such as cranes at ship/boat building and repair facilities, log stackers, industrial
parts, trucks and other vehicles stored outside.
Drain oil and fuel filters before disposal. Discard empty oil and fuel filters, oily rags,
and other oily solid waste into appropriately closed and properly labeled containers
that comply with the Uniform Fire Code or International Building Code.
To store liquids, use containers, such as steel or plastic drums, which are rigid and
durable, corrosion resistant to weather and fluid content, non-absorbent, water
tight, rodent-proof, and equipped with a close-fitting cover.
For temporary storage of solid wastes contaminated with liquids or other potential
polluted materials use dumpsters, garbage cans, drums, or comparable
containers, that are durable, corrosion resistant, non-absorbent, non-leaking, and
equipped with either a solid cover or screen cover to prevent littering. If covered
with a screen, the container must be stored under a roof or other adequate form of
cover.
Where exposed to stormwater, use containers, piping, tubing, pumps, fittings, or
valves that are appropriate for their intended use and for the contained liquid.
Appendix B contains the BMP Maintenance Logs.

needed, and determine whether improvements in O-&-M are needed.
Promptly repair any deterioration threatening the structural integrity of the facilities
and replace clean-out gates, catch basin lids, and rock in emergency spillways.
Ensure that storm sewer capacities are not exceeded. Prevent heavy sediment
discharges to the sewer system.
Regularly remove debris and sludge from BMPs used for peak-rate control,
treatment, etc. Discharge to sanitary sewer if approved by the sewer authority, or
truck to a local or state government approved disposal site.
Clean catch basins when (1) the depth of deposits reaches 60% of the sump depth
when measured from the bottom of basin to the invert of the lowest pipe into or out
of the basin, or
(2) the debris surface reaches six inches from the invert of the lowest pipe. Some
catch basins (for example, WSDOT Type 1L basins) may have as little as 12 inches
for sediment storage below the invert. These catch basins will need more frequent
inspection and cleaning to prevent scouring and to remain compliant. Where these
catch basins are part of a stormwater collection and treatment system, the system
owner/operator may choose to concentrate maintenance efforts on downstream
control devices as part of a systems approach.
Remove woody debris from catch basins as frequently as needed to ensure proper
operation of the catch basin.
Post warning signs; “Dump No Waste - Drains to “Streams,” “Lakes,” or emboss
on or adjacent to storm drain inlets, where practical

3.1.18.
Illicit Discharge
Water from washing, steam cleaning, and/or pressure washing vehicles or equipment is
considered process wastewater. This process wastewater must not be comingled with
stormwater or enter storm drains. It must be collected in a tank for off-site disposal or
discharged to sanitary sewer, with written approval from the local sewer authority.
During monthly site inspections, look for signs of illicit discharges, especially during dry
weather when stormwater should not ordinarily be discharging from the site. Each
monthly site inspection must include:
Observations at stormwater sampling locations and areas where stormwater
associated with industrial activity is discharged off-site; or discharged to waters of
the state, or to a storm sewer system that drains to waters of the state.
Observations for the presence of floating materials, visible oil sheen, discoloration,
turbidity, odor, etc., in the stormwater discharge(s).

Observations for the presence of illicit discharges such as domestic wastewater,
noncontact cooling water, or process wastewater, including leachate.
Reference Section 3.1.3: Operational Source Control BMPs for Illicit Connections
to Storm Drains
If an illicit discharge is discovered, Ecology must be notified within seven days. The illicit
discharge must be eliminated within 30 days.
3.2
STRUCTURAL SOURCE CONTROL BMPS
3.2.1. Mandatory BMPs
The following will be implemented as mandatory structural source control BMPs required
by Condition S3 of the Industrial Stormwater General Permit.
Use grading, berming, or curbing to prevent runoff of contaminated flows and divert
run-on away from manufacturing, processing, and material storage areas
(including loading and unloading, storage, disposal, cleaning, maintenance, and
fueling operations).
Perform all cleaning operations indoors, under cover, or in bermed areas that
prevent stormwater runoff and run-on and capture overspray.
Ensure that washwater drains to a collection system that directs the washwater to
further treatment or storage and not to the stormwater drainage system.
3.2.2. Mandatory Applicable BMPs - Structural Source Control BMPs for Loading and
Unloading Areas for Liquid or Solid Material
All Loading/ Unloading Areas:
Consistent with Uniform Fire Code requirements (Appendix IV-D R.2 of the
Stormwater Management Manual for Western Washington) and to the extent
practicable, conduct unloading or loading of solids and liquids in a manufacturing
building, under a roof, or lean-to, or other appropriate cover.
Berm, dike, and/or slope the loading/unloading area to prevent run-on of
stormwater and to prevent the runoff or loss of any spilled material from the area.
Large loading areas typically are not curbed along the shoreline. As a result,
stormwater passes directly from the paved surface into surface water. To prevent
this run-off, install curbs along the edge, or slope the edge so that the stormwater
can flow to a storm drain system that leads to an approved treatment BMP.
Pave and slope loading/unloading areas to prevent the pooling of water. The use
30 March 2018
AGE Proposal No. 18-4323
Page 19 of 27
of catch basins and drain lines within the interior of the paved area must be
minimized, as they will frequently be covered by material. Alternatively, catch
basins should be placed in designated “alleyways” that are not covered by
material, containers or equipment.
Loading/Unloading Docks:
Install/maintain overhangs or door skirts that enclose the end of the trailer to
prevent contact with rainwater.
Design the loading/unloading area with berms, sloping, etc. to prevent the run-on
of stormwater.
Retain on-site the necessary materials for rapid spill cleanup.
3.2.3. Mandatory Applicable BMPs - Structural Source Control BMPs for Maintenance
and Repair of Vehicles and Equipment
Conduct all maintenance and repair of vehicles and equipment in a building, or
other covered impervious containment area that is sloped to prevent run-on of
uncontaminated stormwater and runoff of contaminated stormwater.
The maintenance of refrigeration engines in refrigerated trailers may be conducted
in the parking area so long as caution is used to avoid the release of engine or
refrigeration fluids to storm drains or surface water.
Park large mobile equipment, such as forklifts, in a designated contained area.
3.2.4. Mandatory Applicable BMPs - Structural Source Control BMPs for Mobile Fueling
of Vehicles and Heavy Equipment
Automatic fuel transfer shut-off nozzles.
An adequate lighting system at the filling point.
3.2.5. Mandatory Applicable BMPs - Structural Source Control BMPs for Outside
Storage of Liquid, Food Waste, or Dangerous Waste Containers
Keep containers with Dangerous Waste, food waste, or other potential pollutant
liquids inside a building unless this is not feasible due to site constraints or
Uniform/International Fire Code requirements.
Store containers in a designated area, which is covered, bermed or diked, paved
and impervious in order to contain leaks and spills. Slope the secondary
containment to drain into a dead-end sump for the collection of leaks and small
spills.
30 March 2018
AGE Proposal No. 18-4323
Page 20 of 27
For liquid wastes, surround the containers with a dike. The dike must be of
sufficient height to provide a volume of either 10 percent of the total enclosed
container volume or 110 percent of the volume contained in the largest container,
whichever is greater.
Where material is temporarily stored in drums, consider using a portable temporary
secondary system in lieu of a permanent system as described above.
Place containers mounted for direct removal of a liquid chemical for use by
employees inside a containment area as described above. Use a drip pan during
liquid transfer.
3.2.6. Mandatory Applicable BMPs - Structural Source Control BMPs for Storage of
Liquids in Permanent Aboveground Tanks
Locate permanent tanks in impervious (Portland cement concrete or equivalent)
secondary containment surrounded by dikes, or use UL Approved double-walled
tanks. The dike must be of sufficient height to provide a containment volume of
either 10 percent of the total enclosed tank volume or 110 percent of the volume
contained in the largest tank, whichever is greater. The aboveground storage tank
located at the facility is located within the maintenance shop and not exposed to
stormwater.
Slope the secondary containment to drain to a dead-end sump or equivalent, for
the collection of small spills.
Include a tank overfill protection system to minimize the risk of spillage during
loading.
3.3
Treatment BMPs
3.3.1. Mandatory BMPs
The following will be implemented as mandatory structural source control BMPs required
by Condition S3 of the Industrial Stormwater General Permit.
Use Treatment BMPs consistent with the applicable documents referenced in
Condition S3.A.3.
Employ oil/water separators, booms, skimmers or other methods to eliminate or
minimize oil and grease contamination of stormwater discharges.
Obtain Ecology approval before beginning construction/installation of all treatment
BMPs that include the addition of chemicals to provide treatment.
30 March 2018
AGE Proposal No. 18-4323
Page 21 of 27
3.3.2.
Mandatory Applicable BMPs - Treatment BMPs for Maintenance and Repair of
Vehicles and Equipment
Contaminated stormwater runoff from vehicle staging and maintenance areas
must be conveyed to a sanitary sewer, if allowed by the local sewer authority, or
to an API or CP oil/water separator followed by a basic treatment BMP, applicable
filter, or other equivalent oil treatment system. All Estes maintenance and repair of
vehicles and equipment is performed within the maintenance building and is not
exposed to stormwater. Therefore, Estes is not required to have an oil water
separator at the facility.
3.3.3. Mandatory Applicable BMPs - Treatment BMPs for Outside Storage of Liquid,
Food Waste, or Dangerous Waste Containers
For contaminated stormwater in the containment area, connect the sump outlet to
a sanitary sewer, if approved by the local Sewer Authority, or to appropriate
treatment such as an API or CP oil/water separator, catch basin filter or other
appropriate system (see Volume V of the Stormwater Management Manual for
Western Washington). Equip the sump outlet with a normally closed valve to
prevent the release of spilled or leaked liquids, especially flammables (compliance
with Fire Codes), and dangerous liquids. Open this valve only for the conveyance
of contaminated stormwater to treatment.
Another option for discharge of contaminated stormwater is to pump it from a deadend sump or catchment to a tank truck or other appropriate vehicle for off-site
treatment and/or disposal.
3.3.4. Structural Treatment BMPs
The following will be implemented as mandatory structural source control BMPs required
by Condition S3 of the Industrial Stormwater General Permit.
Sediment control BMPs such as detention ponds, vegetated filter strips, bio
swales, or other permanent sediment control BMPs to minimize sediment loads in
stormwater discharges were not practical. Estes does not have the required space
on their facility for these BMPs. Therefore, Estes used drain inlet filters to perform
this function.
The SWPPP listed the source of the zinc as the galvanized sheet metal roof on the
terminal buildings. An investigation to the cause/sources of the pollutant was determined
to be the east end of the warehouse roof of the terminal building. Additional pollution
sources included forklift truck activity, truck tire debris, breaks dust debris for metals and
sediments.
In August 2016, Cleanway drain inlet filtration units (CleanWay Storm Clean) were
installed inside drain inlet within the parking lot and trailer storage area. A total of
30 March 2018
AGE Proposal No. 18-4323
Page 22 of 27
12 drain inlets have filtrations units installed. These treatment BMPs were intended
to remove pollutants such as suspended solids, oil and metals from stormwater at
catch basins, sumps or other stormwater collection and conveyance system
components. Media have been installed to treat contamination associated with
sediments and metals (total and dissolved). Cleanway filter designs and media
information is attached in SWPPP.
In September 2017, downspouts filters (Bio Clean) were installed for the metal
component roof section of the warehouse building. The proposed treatment
required installation on the downspouts because truck traffic has the potential to
damage surface grade treatments. Bio Clean in-line filtration units were installed
into new poly vinyl chloride (PVC) downspouts; equipped with industrial media for
zinc and metals removal. Bio Clean downspout treatment information is attached
in the SWPPP.
Semi-annual replacement of filter media (catch basin or drain inlet and roof
downspout) is planned and increased filter servicing (sediment removal) can be
conducted, if necessary, based on the quarterly stormwater sampling data.
An active stormwater treatment control system design is currently underway in
accordance with Condition S8.D. A Level 3 Corrective Action Plan (CAP) will be
prepared as required by the Permit, including a peak flow determination for the site
in accordance with the Western Washington hydraulic model. The parameters will
be to achieve 72-75% of the 2-year stormwater discharge event and/or the 15minute maximum discharge rate.
A set of operational parameters have been secured from treatment manufacturers
for the evaluation and CAP finalization.
3.4.
Erosion and Sediment Control BMPs
Although most of the site is paved or otherwise vegetated, the following erosion and
sediment control BMPs will be implemented where appropriate as required by
Condition S3.
4.0.
SAMPLING PLAN
4.1
DISCHARGE LOCATIONS
One stormwater outfall discharge from the facility. Existing catch basins drain to a single
catch basin (Catch Basin 1) located on the northwest side of the property prior to draining
into the City of Auburn municipal storm drain at Outfall 1. Estes performs grab sampling
at the discharge point of Catch Basin 1 which discharges all catch basins on the property.
This sampling point is identified as “PT1” and is shown on the Site Map in Figure 2.
30 March 2018
AGE Proposal No. 18-4323
Page 23 of 27
Because the entire site drains to Catch Basin 1 and discharges at Outfall 1, all of the
industrial activities, potential pollutants and BMPs described in previous sections apply to
discharge at this outfall.
4.2
STAFF RESPONSIBLE FOR SAMPLING
Sampling will be conducted by the Estes Terminal Manager or designated representative,
who has been trained on proper procedures.
4.3
SAMPLE COLLECTION AND HANDLING
Discharge will be sampled at least once per quarter. The stormwater discharge storm
event, that results in a discharge will be sampled, within the first 12 hours of discharge.
The following checklist shall be used for sample collection and handling:
1. Call Nisqually Environmental or the designated analytical laboratory. Request a
basic Stormwater Sampling Kit, including sample bottles, directions, ice and
cooler.
2. Review kit directions and contents. Label and date jars.
3. Take sampling kit to sampling point (PT1). Bring sampling field book for
recordkeeping.
4. During sampling:
Keep hands away from jar openings.
Sample from central portion of flow in the catch basin.
Measure pH and Turbidity (if appropriate).
AVOID touching or disturbing the bottom of the channel or stirring up particles.
Fill samples directly into jars, being careful not to spill any preservative.
DO NOT rinse or overfill bottles.
Fill jars to within one-half inch of top and cover tightly with lids.
Fill out the labels, put samples in the cooler on ice, and fill out the chain of
custody form.

AQUIP® OPERATION & MAINTENANCE MANUAL
Important!
Do not neglect upstream source control and stormwater management once Aquip is installed. This may
result in the premature fouling of the Aquip filtration and pollutant reduction capacity, shortening bed life.
Do not flush spills or otherwise use Aquip to capture pollutants from stormwater drain line jetting or
pavement washing.
Lifting Aquip once the media has been installed may result in damage to the tank. All the media except
the underdrain gravel should be removed before attempting to move Aquip.
Regular maintenance of the media surface will ensure optimal performance results as well as increase
the lifespan of the media bed. The removed media needs replacement after removing more than 2”.
Media replacement should not be done in the place of seasonal maintenance.
Do not pressure-wash or rinse the inside of the Aquip prior to removing the filtration media.
Stormwater sampling should be done with care. Use new sampling bottles and avoid contaminating
samples with dirt from the Aquip sample port or your hands.
Freezing conditions can cause damage to the external plumbing on Aquip. Please refer to this manual to
take the necessary precautions.

AQUIP® OPERATION & MAINTENANCE MANUAL
1 Introduction and System Description
The Aquip (Figure 1, below) is a passive adsorptive depth filtration technology designed specifically for
reduction of stormwater pollutants such as suspended solids, turbidity, heavy metals, nutrients and
organics from industrial sites. The Aquip is a patented system that uses a pretreatment chamber
followed by a series of inert and adsorptive (depending on the configuration) filtration media to
effectively trap pollutants in a pre-configured package. The Aquip structure is typically concrete (C),
steel (S) or pre-cast concrete blocks for high flow applications (HF). Pollutant removal within the
pretreatment chamber occurs by gravity settling; pollutant removal within the filtration chamber occurs
through a combination of chemical complexing, co-precipitation, adsorption, absorption, microsedimentation, filtration and biological degradation.
Figure 1: Aquip Stormwater Filtration System
1.1 Aquip Features
(1) Inlet: Polluted stormwater flows into the Aquip via the inlet pipe which controls and monitors the
flow into the system.
a. Inline Flow Meter: An electromagnetic flow meter displays the operating flow rate and
the total volume of water treated by the Aquip. The volume of water treated should be
recorded at regular intervals to help in planning maintenance intervals.
b. Flow Control Valve: The valve used to calibrate the proper flow rate into the Aquip.
c. Inlet Check Valve: This check valve keeps the standing water level in the pretreatment
chamber at the correct level.
d. Inlet Sample Port: Allows for the convenient sampling of the inlet stormwater.

AQUIP® OPERATION & MAINTENANCE MANUAL
(2) Pretreatment: This chamber is customized to improve the quality of the stormwater prior to
treatment in the filtration chamber. The pretreatment chamber can be configured for settling
coarse solids, skimming free floating oil, conditioning the stormwater for dissolved metals
removal, or optimizing organics removal, or any combination thereof.
The conditioning option is the most common configuration. The Aquip uses a passive
pretreatment process which accelerates the output of alkalinity, an important constituent in
natural waters. This pretreatment works synchronously with several of the adsorptive filtration
media layers within the filtration chamber. The pretreated water helps positively charged metallic
ions find negatively charged alkalinity compounds. Some of these positive and negative ions
form insoluble complexes that are removed in the filtration chamber. Within the Aquip filtration
treatment chamber some of the metals are removed as precipitates by micro-sedimentation.
Because of the low alkalinity common to most stormwater, particularly those from facilities where
most of the surface is paved, there is not lingering effect of the pretreatment process.
Other options are the basic solid settling configuration or the oil water separator design. All
configurations come standard with a precautionary oil skimmer that helps to trap and absorb
free oil inside of the pretreatment chamber.
(3) Inlet Distributor: Water from the pretreatment chamber flows into the inlet distributor and is
dispersed along the full length of the filter media bed optimizing the contact area of stormwater
with filtration media. The energy dissipation fabric lies beneath the distributor to prevent
scouring of the media bed.
(4) Filtration Treatment: Layers of inert and adsorptive media make up the media bed which filters
out stormwater pollutants such as metals, particulates, oil, organics and nutrients. Once filtered
through the media bed, clean stormwater flows into the underdrain located along the bottom of
the media bed.
(5) Outlet Manifold:
a. Outlet Sample Port: Allows for the convenient sampling of treated stormwater.
b. Adjustable Head Control: Clean stormwater leaving the filter bed passes through the
adjustable head control. This device can be adjusted in the field and assures optimal
water-filter media contact under a range of operating conditions.
(6) Emergency Overflow: The upturned elbow provides a means of bypass for stormwater if the
media bed is no longer draining at a rate that keeps pace with the influent design flow rate. A
passive overflow indicator on the outside of the Aquip tank visually indicates when an
emergency overflow has occurred. After each overflow event, this feature needs to be reset by
releasing the water stored inside the overflow indicator by turning the petcock valve at the bottom
of the device.
(7) Outlet: Clean stormwater is discharged from the Aquip through the outlet pipe to an existing
conveyance line or to an infiltration gallery or other means of disposal or reuse.
(8) Sample Port: Effluent stormwater samples are collected from the sample tap installed on the
outlet manifold.

Typical Installation Configuration
In most applications, the Aquip system is installed as a retrofit and installation is above ground. In this
case, stormwater needs to be pumped from a below-ground vault or catch basin to the Aquip. In some
cases, stormwater is first pumped to an above-ground storage tank and stormwater is drained by gravity
through the Aquip. A configuration with a storage tank is referred to as “Storage Discharge” (Figure 2,
left). Configurations without a storage tank are called “Direct Discharge” (Figure 2, right).

AQUIP® OPERATION & MAINTENANCE MANUAL
2 Aquip Operations
Regular inspection and maintenance is required for the proper operation of the Aquip. Site conditions
vary such that the maintenance requirements cannot be prescribed without regular inspections.
Inspections determine the type and frequency of maintenance required and regular maintenance keeps
the Aquip operating at optimal conditions to improve the performance and media longevity.
2.1 Wet Start-up Procedures
The Aquip is typically installed during dry weather when there is not sufficient stormwater available to
complete the final steps to put the Aquip online. StormwateRx LLC personnel will leave the Inlet Flow
Control Valve set to half open until the flow rate to the system can be calibrated. During the first storm
event, it is imperative that the owner calibrate the flow rate through the system to that designated in the
Installed Aquip Project Specification sheet at the front of this manual.
Step 1. Fill above ground storage tanks: For Storage Discharge configurations only. For Direct
Discharge, proceed to Step 2. Close the outlet valve from the storage tank (or the Inlet Flow
Control Valve to the Aquip) and fill the above ground storage tank(s) until the water level is
near the top of the tank(s).
Step 2. Flow calibration: Adjust the Inlet Flow Control Valve until the Inline Flow Meter indicates
the design/nameplate flow rate as noted on the flow meter (Figure 3, page 5). The design
flow rate is listed in the Installed Aquip Project Specification sheet at the front of this manual.
Step 3. Inlet Distributor adjustment: Adjust the height of the Inlet Distributor until each arc of
water is roughly uniform across the entire length of the Aquip filtration chamber (Figure 4,
page 6). This is done by tightening or loosening the plastic washers on the threaded rod
suspending the Inlet Distributor.
Step 4. System operation: Monitor system throughout the first storm event to confirm stormwater is
passing through the Aquip. Inspect outfall point of stormwater conveyance line to confirm
there is free discharge. Note that the Aquip filter performance improves (outlet water clarity
should improve) after the first or second storm event. This occurs because the stormwater
particulates that are captured by the Aquip filtration bed in early storm events actually assist
the particle filtration process, thereby producing better water clarity with time. This process
is known as “bed seasoning.”
Step 5. After storm inspection: Inspect the Aquip after the storm event. Normally, owners observe
an accumulation of fine solids over the top of the filtration chamber. If the thickness is
greater than 1/4-inch, additional upstream source control may be beneficial to reduce
sediment loading to the system (see Section 7).

2.2 Inspections
During the first rainy season, inspections should be conducted weekly or every two to three storms to
establish site-specific inspection and maintenance intervals. Regular inspections will verify that the
system is in good operating condition and should be recorded as part of the monthly inspection program
and the facility Stormwater Pollution Prevention (or Control) Plan (SWPPP or SWPCP). Inspections are
also recommended after every major storm event. An inspection report template is included at the end of
this manual to assist with record keeping.
AN INSPECTION DURING A RAIN EVENT IS THE BEST METHOD OF ASSESSING
HOW WELL THE AQUIP SYSTEM IS OPERATING
Flow meter
•
Verify that the flow rate to the Aquip matches the design flow rate. Operating the Aquip at a
rate other than the designated design flow rate will affect the system performance and may
not be allowable under the stormwater permitting rules. Adjust the flow rate as necessary.
Opening the flow control valve such that the flow rate is increased will decrease system
performance. The flow rate should only be adjusted when the storage tank(s) are full for the
Storage Discharge system configuration.
Pretreatment Chamber
For Aquip SBE with pretreatment media
•
•
Inspect the amount and distribution of the pretreatment media. There should be at least 3
inches of pretreatment media evenly distributed across the media grates.
Inspect for the accumulation of solids and debris on top of the pretreatment media. Before

AQUIP® OPERATION & MAINTENANCE MANUAL
•
Inspect for solidification of the pretreatment media. If present, clumps of media should be
broken up with a shovel.
For Aquip SOI or SOE with oil coalescing packs
•
•
Inspect the water surface for heavy oil sheen. If a heavy sheen is present, remove the
accumulated oil from the surface.
Inspect the side walls of the Pretreatment Chamber for heavy oil and debris accumulation. If
heavy oil and debris are present, follow the maintenance steps described in the Section 3.3.
Inlet Distributor
•
•
Inspect the perforations for the accumulation of debris. The accumulation of any debris
should be removed by hand.
During a storm event, verify that the flow of water out of the perforations is uniform the entire
length of pipe. For storage Discharge configurations, the Inlet Distributor should only be
adjusted when the storage tank(s) are full.
Media Bed
•
•
•
•
During a storm event, observe the water level above the media bed relative to the Inlet
Distributor. Note that the water level may increase during the first 15 minutes of operation.
Inspect the accumulation of solids on the surface of the media (Figure 4, below). Observe the
appearance of the solids and its distribution across the media surface. If more solids than
sand are visible on top of the media, refer to Routine Surface Maintenance Section 3.1.1.
Check for a hardened or brittle media surface in the absence of solids accumulation. If the
media surface is hardened, break up the media surface to help restore hydraulic capacity.
Verify that the Energy Dissipation Fabric is clean and laying flat beneath the Inlet Distributor.
The Energy Dissipation Fabric may be re-anchored by pushing small amounts of filter sand
over the fabric at various intervals.
Outlet Sample Port
•
Collect the effluent from the Aquip to observe changes in water clarity. The clarity of the
water is best observed using a clear glass/plastic container. As mentioned earlier, water
clarity should improve after the first few storms.

AQUIP® OPERATION & MAINTENANCE MANUAL
2.3 Optimal Operating Conditions
The Aquip should be maintained regularly for optimal performance and media longevity. Observe the
water level within the Filtration Chamber to determine optimal operation. Both of the following conditions
need to be met for the Aquip to be operating at optimal conditions:
• Water has been draining through the Inlet Distributor continuously for 15 minutes or more.
•
The water level within the filter is above the surface of the media and below the Inlet
Distributor (Figure 5, below).
However, for LIGHT RAIN or INTERMITTENT RAIN conditions, neither of the two conditions may be
established.
Should the water level within the Filtration Chamber reach the Inlet Distributor, maintenance should be
performed to re-establish the proper flow through the Aquip (see Section 3).
Figure 5. Best operating water level in filtration chamber for
optimal pollutant removal conditions
2.4 Weatherizing the System for Freezing Weather
In areas that are prone to continuous freezing weather, StormwateRx LLC recommends weatherizing
certain components of the Aquip filtration system and/or purchasing the pre-installed freeze protection
package
Online Application – Keeping Filter In Service
This procedure applies to Aquip systems that must stay online through periods of freezing weather.
Freeze Protection Package
For systems with a StormwateRx Freeze Protection package, turn the system on. The freeze protection
system is thermostatically controlled with radiant heaters to keep the filter body above freezing. The
freeze protection package can only be obtained at time of the Aquip purchase.
© 2018 StormwateRx LLC, All Rights Reserved.
v017 | 7
AQUIP® OPERATION & MAINTENANCE MANUAL
If your system does not have factory-installed freeze protection package, owners may apply heating
elements to the bottom of the Aquip tank to help keep the filter media from freezing. These heating
elements can include, but are not limited to, heat panels, blankets, and/or coils.
Freeze Protect Inlet Piping
Heat tracing and insulation of all above ground inlet plumbing is recommended (Figure 6, below). For
many Aquip inlet plumbing designs, the pump discharge includes a check valve. This causes the inlet
plumbing to stay full of water and may be subject to freezing. Above-ground inlet plumbing for the Aquip
system is typically 5 – 10 linear feet.
Figure 6. Aquip inlet line heat tracing (left) and Aquip inlet line insulation (right).
Freeze Protect the Pretreatment Chamber
The pretreatment chamber will either have standing water in it, up to the bottom of the riser pipe
connecting the pretreatment chamber to the filtration chamber (Figure 7, left, page 9), or will be pumped
down below the pretreatment rack with the pretreatment pump (Figure 7, right, page 9, shown with
pretreatment rack removed). In either case, the standing water in the pretreatment chamber may freeze
or develop a surface ice skim layer, depending on the extent of freezing weather. This thin layer of ice
will not impair operations and should break up as the water rises with pumped flow.

Freeze Protecting the Filtration Chamber
The filtration chamber contains loose filter media and accumulated sediment for Aquip systems that
have been in operation. The wetted filter media may become clumpy as the pore water within the
filtration media granules freezes. In anticipation of a freezing event, the following steps are
recommended for the filtration chamber of treatment systems without freeze protection:

1. Drain down any standing water in the filtration chamber through the filtration chamber drain-down
valve (Figure 9, below).
2. Perform a routine maintenance to remove accumulated sediment and media containing
sediment.
3. Add at least one inch of topper media to insulate the remaining used filter media in anticipation of
the freezing event.
Figure 9. Filtration chamber draindown valve.
Freeze Protecting Outlet Piping
Outlet piping from the Aquip should be empty between storm events and as such, freezing of the outlet
manifold should not occur.
Offline Application – Taking the Filter Out of Service for the Winter
This procedure applies to Aquip systems that:
• operate in areas where a hard, long winter freeze is typical;
• do not have a freeze protection package; and,
• are taken offline for the winter season.
Seasonally Decomissioning Inlet Piping
Inlet piping between the check valve and the Aquip filter will be full of water and could freeze during cold
weather. To prevent damage:
1. Turn off the pump to the system.
2. Drain the pretreatment chamber through the pretreatment drain-down valve* (Figure 10, page
11).
3. Drain the inlet piping using the inlet sample port (Figure 10, page 11).
Seasonally Decommissioning the Pretreatment Chamber

The Filtration Chamber contains loose filter media and accumulated sediment for Aquip systems that
have been in operation. The wetted filter media may become clumpy as the pore water within the
filtration media granules freezes. The following steps are recommended for the Filtration Chamber in
anticipation of taking the unit offline for the season:
1. Drain down any standing water in the Filtration Chamber through the filtration chamber draindown valve* (Figure 11, below).
2. Perform a routine or seasonal maintenance to remove accumulated sediment and media
containing sediment.
3. Add new filter media to insulate the remaining used filter media for the season. Snow may
accumulate in the filter. This is normal and acceptable.
4. Remove the filtration chamber drain plug on the underside of the Filtration Chamber. This will
drain any standing water in the bottom of the Filtration Chamber.

Seasonally Decomissioning Outlet Piping
Outlet piping from the Aquip should be empty between storm events and as such, freezing of the outlet
manifold should not occur.
*Warning: Draining water onto the ground may freeze and create a slip hazard. Consider draining
the water back to the sump or another location using hose or tubing.
2.5 Sampling Protocol and Methodology
Water quality samples should be taken only when the system has been maintained and is operating
effectively (see Section 2.3). The inlet and outlet sample ports on the Aquip provide a convenient and
reliable method of taking samples.
AFTER INSTALLING NEW FILTRATION MEDIA, OPERATE THE AQUIP FOR TWO HOURS
BEFORE COLLECTING AN EFFLUENT SAMPLE
Use caution when collecting water quality samples to prevent contamination of the sample bottles. A
small amount of dirt goes a long way to contaminating a stormwater sample. Make sure the sample port
and your hands or gloves are clean BEFORE collecting your compliance sample. The following
precautions should be taken immediately before sampling:
1.
Using a CLEAN cloth, wipe off any visible dirt from the sample port valve spigot.
2.
Open sample valve and allow water to flush through the port for a minimum of 10 seconds.
3.
Use the proper unused sample bottle – do not reuse sample bottles.
4.
Do not touch the sample bottle to the sample port.
5.
Do not put fingers inside or around the sample port or the mouth of the sample bottle.
6.
For sample bottles with liquid preservative inside, do not allow the bottle to overflow.
7.
Cap the sample bottle as quickly as possible. Store on ice. Ice helps reduce the amount of
metals that move from particulate to dissolved phase and reduces the rate of growth of
biological organisms within the sample bottles.
StormwateRx recommends sampling the inlet to the Aquip each time that the outlet is sampled. Without
the inlet sample data, StormwateRx LLC cannot diagnose or provide recommendations on tuning
system performance. The inlet should be sampled approximately 15 minutes before sampling the outlet
to get the most representative inlet/outlet sample pair.
3 Maintenance Guidelines
The Aquip, like all filtration systems, requires periodic maintenance to restore the system to its original
effectiveness. The type and frequency of maintenance required for the Aquip varies significantly from
site to site due to differences in facility operations, upstream stormwater management, and rainfall
frequency. Routine inspections conducted on the Aquip will help to determine how frequently to maintain
your Aquip stormwater filter (see Section 2.2).
LOADING TO AND MAINTENANCE OF THE AQUIP CAN BE REDUCED
BY IMPROVING UPSTREAM SOURCE CONTROL BMPS.

AQUIP® OPERATION & MAINTENANCE MANUAL
3.1 Filter Media Maintenance
Maintaining the filter media is the most important step for achieving the optimal results from your Aquip
filtration system. The media can be maintained either by cleaning and leveling the surface or replacing
specific layers of media. The type of maintenance required is based upon the flow rate through the
Aquip and/or the type of pollutants entering the system. Media maintenance is done to provide uniform
flow downward through the media, preventing preferential flow and utilizing the entire surface area of the
media bed. By providing uniform flow, treatment is maximized.
The layers of media have been configured in a specific arrangement to provide treatment for the
identified pollutants in your stormwater. Refer to Figure 12, below, for media layer nomenclature.
Figure 12. Enhanced and basic media bed configurations
3.1.1
Maintenance Type I – Routine Surface Maintenance
Refer to Figure 12 to identify the media and fabric layers described in this section.
Maintenance Description
A Maintenance Type 1 - Routine Surface Maintenance consists of cleaning the entire media surface by
shoveling off and removing the top ¼ - ½ inches of media with a square point shovel. The media below
the Energy Dissipation Fabric should also be clean at this time. The surface of the media should then be
leveled using the filter shovel provided.
The Inlet Distributor and Energy Dissipation Fabric should also be inspected and cleaned if necessary at
the time of Routine Surface Maintenance (see Section 2.2).
The removed media should be replaced after 2” of the top inert layer is removed as a result of routine
surface maintenances. Replenish the removed media with new media if less than 7” of inert media
remains on top of the media bed.
SURFACE MAINTENANCE AND MEDIA REPLENTISHMENT DO NOT SERVE AS A
REPLACEMENT TO SEASONAL MAINTENANCE BUT DO EXTEND SYSTEM RUN-TIMES
© 2018 StormwateRx LLC, All Rights Reserved.
v017 | 13
AQUIP® OPERATION & MAINTENANCE MANUAL
Maintenance Timing/Frequency
A Routine Surface Maintenance should be conducted when the water level within the Aquip begins to
stack up. Optimal operating conditions for the Aquip occur when the following conditions exist:
1. The Aquip has been operating for more than more than 15 minutes.
2. The water level within the Filtration Chamber reaches a point within 3 inches of the lowest point
on the Inlet Distributor (Figure 5, page 7).
A Routine Surface Maintenance may need to be done as frequently as every 3 – 4 weeks depending on
the amount of loading on the Aquip.
Maintenance Steps
The steps in conducting a Routine Surface Maintenance are:
1. Remove and set aside the Energy Dissipation Fabric (Fabric Layer G1, see Figure 12, page 13).
2. Clean the Energy Dissipation Fabric if necessary.
3. Clean the entire surface of the media by shoveling off the accumulated solids and the top ¼ - ½
inches of media (approximate) (Figure 12). The newly exposed media should look cleaner than
the removed media. Remove more depth if necessary.
4. Dispose of the removed media and accumulated debris.
5. Level the surface of the media.
6. Measure the depth of the remaining inert media layer by inserting a shovel directly down into the
media until it reaches the lower-lying fabric layer (Figure 13, below). This will indicate the depth
of the inert media layer.
7. Replenish the removed media with new media if less than 7” of the inert layer remains (more
than 2” of the inert layer has been removed over the course of several surface maintenances).
8. Re-install the Energy Dissipation Fabric beneath the Inlet Distributor using scoops of sand to
hold down the edges.

AQUIP® OPERATION & MAINTENANCE MANUAL
3.1.2
Maintenance Type II – Seasonal Maintenance
Refer to Figure 12 (page 13) to identify the media and fabric layers described in this section.
Maintenance Description
During a Seasonal Maintenance, the inert media on top (Media Layer A) is replaced to restore the
proper flow rate through the Aquip. Typically, dirt and debris are trapped within the top layer of media
which eventually causes the media to plug.
Maintenance Timing/Frequency
Media replacement is necessary when the proper flow rate through the Aquip cannot be established by
a Routine Surface Maintenance or lowering the Adjustable Head Control (see Section 3.2). Seasonal
Maintenance is recommended when stormwater sampling shows consistent pollutant reductions and
solids loading in the lower-lying media (Media Layer B) is not appreciable.
Maintenance Steps
StormwateRx can provide a quotation for Seasonal Maintenance which includes the new media, filter
fabric, and optional technical supervision at the time of the maintenance. The steps to conduct a
Seasonal Maintenance are:
1. Set up safety equipment if the system is near vehicle and pedestrian traffic.
2. Sparingly pressure-wash or hand-wipe the side walls of the Aquip prior to removing any media.
Cleaning the inside walls of the Aquip will allow the operator to observe the system’s most recent
operating water level based upon the scum line left behind inside of the Aquip. No detergent or
hot water should be used when cleaning the insides of the Aquip.
3. Remove and dispose of the Energy Dissipation Fabric (Fabric Layer G1, see Figure 12, page
13).
4. Excavate the spent filter media (Media Layer A) down to the first layer of geotextile fabric (Fabric
Layer G2). A shovel or vactor truck may be used to remove the filter media (Figure 14, page 16).
See Section 5 for media disposal.
5. Remove Fabric Layer G2 and inspect the underlying filter media (Media Layer B).
6. Break up the top three to six inches of media to rejuvenate Media Layer B. Level and smooth the
filter media.
7. Re-install Fabric Layer G2 over the top of Media Layer B.
8. Install the new inert filter media (Media Layer A). Media should be added in uniform, level layers
using the level indicators on the side walls of the Aquip as a guide. Each media layer should be
leveled before adding the next media layer.
9. Install the new Energy Dissipation Fabric (Fabric Layer G1) on top Media Layer A using scoops
of sand to hold down the edges.
When conducting a Seasonal Maintenance, the Pretreatment Chamber should also be maintained (see
Section 3.3).
NO DETERGENT OR HOT WATER SHOULD BE USED

3.1.3
Maintenance Type III – Full Maintenance
Refer to Figure 12 (page 13) to identify the media and fabric layers described in this section.
Maintenance Description
A Full Maintenance replaces all the filtration media (Media Layers A and B) not including the underdrain
gravel (Media Layer C). The filtering capacity of the media can be exhausted due to a combination of
heavy loading, inadequate maintenance of the Aquip, and extended Aquip run-times.
Maintenance Timing/Frequency
Full Maintenance is recommended when a decline in treatment is observed in the water quality sampling
and Routine Surface Maintenance is no longer capable of restoring the proper flow. Significant loading
in the lower-lying media layers (Media Layer B) will often accompany a decline in treatment.
Maintenance Steps
StormwateRx can provide a quotation for a Full Maintenance which includes the new media, filter fabric,
and optional technical supervision at the time of the maintenance. The steps to conduct a Full
Maintenance are:
1. Set up safety equipment if the system is near vehicle and pedestrian traffic.
2. Sparingly pressure-wash or hand-wipe the side walls of the Aquip prior to removing any media
as shown in Figure 15, page 17. Do not use any detergents. Cleaning the inside walls of the
Aquip will allow the operator to observe the system’s most recent operating water level based
upon the scum line left behind inside of the Aquip. No detergent or hot water should be used
when cleaning the insides of the Aquip.

removing filter media during a full maintenance.
3. Remove and dispose of the Energy Dissipation Fabric (Fabric Layer G1, see Figure 12, page13).
Use a vacuum truck or shovel to remove all spent media (Media Layers A and B). Stop at the
geotextile fabric above the underdrain gravel (Fabric Layer G3). The underdrain gravel (Media
Layer C) should not be removed.
DO NOT PRESSURE WASH OR RINSE THE SIDE WALLS OF THE AQUIP ONCE THE
FILTRATION MEDIA HAS BEEN REMOVED.
4. Remove the PVC plugs located at each of the ends of the underdrain. Also remove the
Adjustable Head Control located on the outlet end of the Aquip by loosening the flanges located
on both sides of this PVC loop (see Figure 1, page 1).
5. Pressure-wash the insides of the underdrain to flush its insides.
6. Reinstall all the PVC plugs on the underdrain and the Adjustable Head Control.
7. Install new geotextile fabric (Fabric Layer G3) on top of Media Layer C.
8. Install the new media layers and filter fabric layers as shown in Figure 12, page 13. Media should
be added in uniform, level layers using the level indicators on the side walls of the Aquip as a
guide. Each media layer should be leveled before adding the next media layer.
9. Install a new Energy Dissipation Layer (Fabric Layer G1) on top layer of the media using scoops
of sand to hold down the edges.
When conducting a full maintenance, the Pretreatment Chamber should also be maintained (see
Section 3.3).
3.2 Adjustable Head Control
The flow rate through the Aquip may be increased using the Adjustable Head Control. This should be
done only when the proper flow rate cannot be established with Routine Surface Maintenance. By
lowering the Adjustable Head Control, the back pressure within the media bed is reduced allowing the
water to flow more freely through the system. The steps to lowering the Adjustable Head Control are:
© 2018 StormwateRx LLC, All Rights Reserved.
v017 | 17
AQUIP® OPERATION & MAINTENANCE MANUAL
1. Loosen all of the bolts on the two flanges located on both sides of the Adjustable Head Control.
Some bolts may need to be loosened further after the flange assembles change their positioning.
2. Rotate the Adjustable Head Control downward away from the Aquip so that it is positioned
parallel to level ground.
3. Evenly tighten the bolts on both flanges. Do not over tighten the bolts. The rubber gasket
between the flange assembles will create a seal with even pressure around the flange.
3.3 Pretreatment Chamber Maintenance
The pretreatment chamber should be maintained when performing a Seasonal or Full Maintenance.
Inspections of the pretreatment chamber should be performed as part of your routine inspections. The
maintenance procedure for each type of pretreatment configuration is described below.
For Aquip SBE with loose pretreatment media
1. Remove and dispose of the solids that have accumulated on the surface of the pretreatment
media.
2. Shovel the loose media to one side of the pretreatment chamber.
3. If the walls of the pretreatment chamber are coated in mud or debris, hose down the walls.
4. Lift up and remove the grate exposed by shoveling aside the media.
5. Suspend a pump off of the floor of the pretreatment chamber and pump down the water beneath
the pretreatment media grates.
6. Shovel or vactor out the accumulated solids on the floor of the pretreatment chamber.
7. Replace grates and level the pretreatment media across the surface of the grates.
For Aquip SOI or SOE with oil coalescing packs
1. Remove the accumulation of any heavy oil sheen on the water’s surface using an oil adsorbent
pad(s) or vactor service.
2. Drain down the pretreatment chamber using the inlet sample port.
3. Remove the coalescing packs from pretreatment chamber.
4. Remove the plastic media blocks from stainless steel frame.
5. Clean the plastic media blocks and stainless steel frame using a low pressure hose.
6. Collect and dispose the removed oil and debris.
7. Reassemble coalescing packs and reinstall in pretreatment chamber.
For Aquip SXI with pretreatment settling
1. Drain down the pretreatment chamber using the inlet sample port.
2. If necessary, hose down the walls of the pretreatment chamber.
3. Suspend a pump off of the floor of the pretreatment chamber and pump down the water beneath
the pretreatment media grates.
4. Shovel or vactor out the accumulated solids on the floor of the pretreatment chamber.

3.4 Oil Skimmer Maintenance
The oil sorbent pad on the oil skimmer should be routinely checked (Figure 16, below). The sorptive
media within the pad will expand when reacting with oil causing the pad to swell in size. The oil sorbent
pad should be replaced once the pad has swollen to its maximum size.
Figure 16. Pretreatment chamber oil skimmer sorbent pad.
3.5 Flow Meter Maintenance
The inside of the flow meter should be cleaned at a minimum of once a year to remove accumulating oil
and dirt. Any accumulation on the surfaces of the electrodes will impede the proper operation of the flow
meter. Remove the flow meter from the influent line on the Aquip and clean the small metal surfaces
(electrodes) and all other surfaces inside of the flow meter using a soft cloth and a 50/50 solution of
denatured alcohol and water. For reference, Table 2 lists the battery types utilized in Aquip flow meters.

If you have any questions about maintenance procedures, contact StormwateRx LLC at (800) 680-3543.
7 Best Management Practice Requirements
Consistently achieving the benchmarks requires rigorous implementation of best management practices
(BMPs) including source control, structural and treatment BMPs. Treatment BMPs (i.e. the Aquip
filtration system) are not designed to operate in the absence of other BMPs. Employing source control
practices on a regular basis is essential to extending the life of the Aquip system, as heavy pollutant
loading can result in a shorter maintenance cycle than expected. The Aquip system is not designed as
an all-in-one treatment device for all types and quantities of stormwater pollution.
Your Stormwater Pollution Prevention (or Control) Plan (SWPPP or SWPCP) should address the BMPs
appropriate for your facility. During normal business operation, make sure that all best management
practices are deployed and maintained. When engaging in operations that are atypical of standard
business practices, please utilize source control measures to prevent heavy pollutant loading into the
Aquip. The following are a few examples of typically employed practices.
•
Sweeping: Sweep site on a regular basis, such as daily, weekly or bi-monthly, especially in
areas of heavy industrial activities.
•
Covering activities: When practical, cover significant materials or industrial operations that are
outdoors, to prevent stormwater contact with potential pollutants.
•
Spill control: When a spill occurs, contain and use onsite spill kits to dispose of material.
•
DO NOT FLUSH SPILLS OF ANY KIND INTO THE AQUIP FILTRATION SYSTEM
•
Catch basin and stormwater conveyance clean out: When cleaning out catch basins and
jetting stormwater conveyance lines, turn off the pump that diverts water to the Aquip system.
This water should not enter the Aquip system.
JETTING YOUR STORMWATER LINES INTO THE AQUIP FILTRATION SYSTEM
IS NOT ADVISED.

4. Ecology approves the Aquip® Enhanced Stormwater Filtration System for treatment at the
above flow rates. The designer shall calculate the water quality design flow rates using the
following procedures:
Western Washington: For treatment installed upstream of detention or retention, the
water quality design flow rate is the peak 15-minute flow rate as calculated using the
latest version of the Western Washington Hydrology Model or other Ecology-approved
continuous runoff model.
Eastern Washington: For treatment installed upstream of detention or retention, the water
quality design flow rate is the peak 15-minute flow rate as calculated using one of the
three methods described in Chapter 2.2.5 of the Stormwater Management Manual for
Eastern Washington (SWMMEW) or local manual.
Entire State: For treatment installed downstream of detention, the water quality design
flow rate is the full 2-year release rate of the detention facility.
5. The Use Level Designation expires on January 1, 2021 unless extended by Ecology, and is
subject to the conditions specified below.
Ecology’s Conditions of Use:
The Aquip® Enhanced Stormwater Filtration Systems shall comply with these conditions:
1. Design, assemble, install, operate, and maintain the Aquip® systems in accordance with
StormwateRx’s applicable manuals and documents and the Ecology Decision.
2. If you pump influent to the system, pump station and bypass design shall follow local
guidelines and codes.
3. StormwateRx, LLC commits to submitting a QAPP for BER review and Ecology approval by
March 1, 2018 that meets the TAPE requirements for attaining a GULD for Basic, Enhanced,
and Phosphorus Treatment. Ecology must review and approve any QAPPs for each
additional field site in Washington State. The sites chosen should reflect the product’s
treatment intent.
4. StormwateRx, LLC shall complete all required testing and submit a TER for Ecology review
by March 1, 2020.
5. Maintenance: The required maintenance interval for stormwater treatment devices is often
dependent upon the degree of pollutant loading from a particular drainage basin. Therefore,
Ecology does not endorse or recommend a “one size fits all” maintenance cycle for a
particular model/size of manufactured filter treatment device.

StormwateRx Aquip system maintenance includes routine media maintenance, inert
media replacement and sorptive media replacement. Maintenance frequency is site
specific and for preventative maintenance purposes is estimated based on elapsed time
and/or cumulative flow through the system. Maintenance includes the following:
Surface Media Maintenance – remove visible surface accumulation of sediment and
discolored inert media from pretreatment and filtration chambers. Top off with new
media to original media height when approximately 3-inches of filter media has been
removed. Surface media maintenance interval averages 1 month.
Inert Media Replacement– replace inert media in filtration chamber when surface
media maintenance program results in a continuous operating filtration chamber water
level of more than two feet. Replacing the inert media protects the underlying sorptive
media and extends sorptive media life. Inert media replacement interval averages 12
months.
Sorptive Media Replacement – replace sorptive media in concert with an inert media
replacement when the operating filtration chamber water level is greater than two feet
despite proper routine and inert media maintenance, or when dissolved pollutant
concentrations exceed regulatory standards. Remove accumulated pretreatment
chamber sediment and media at time of sorptive media replacement. Pollutant
removal capacity of the sorptive media can exhaust due to high loading, inadequate
routine and inert media maintenance, and extended Aquip throughput. Sorptive media
replacement interval averages 24 months.
Owners/operators must inspect Aquip systems for a minimum of twelve months from the
start of post-construction operation to determine site-specific maintenance schedules and
requirements. Conduct inspections monthly during the wet season, and every other
month during the dry season. (According to the SWMMWW, the wet season in western
Washington is October 1 to April 30. According to SWMMEW, the wet season in eastern
Washington is October 1 to June 30). After the first year of operation, owners/operators
must conduct inspections based on the findings during the first year of inspections.
Conduct inspections by qualified personnel, follow manufacturer’s guidelines, and use
methods capable of determining either a decrease in treated effluent flowrate and/or a
decrease in pollutant removal ability.
When inspections are performed, the following findings typically serve as maintenance
triggers:
Effluent flow decreasing to below the design flow rate.
Accumulated sediment discoloration on the media surface is visually more
predominant than filtration media, or
Evidence of bypass or operating water levels more than one foot above the inlet
distributor, or
Standing water remains inside the filtration chamber between rain events, or
Treatment system performance has declined for two or more samples, or
Jar testing indicates that media samples have accumulated more than 20% solids by
volume.

6. StormwateRx, LLC may request Ecology to grant deadline or expiration date extensions,
upon showing cause for such extensions.
7. Discharges from Aquip® Enhanced Stormwater Filtration Systems shall not cause or
contribute to water quality standards violations in receiving waters.

Application Documents:
Aquip® Enhanced Stormwater Filtration System, Technology Assessment Protocol –
Ecology Application for Certification (January 26, 2011; revised May 20, 2011). Prepared
by StormwateRx, LLC. Received May 27, 2011.
Applicant’s Use Level Request:
Conditional Use Level Designation as a Basic, Enhanced, and Phosphorus treatment
device in accordance with Ecology’s 2005 Stormwater Management Manual for Western
Washington.
Applicant’s Performance Claims:
The Aquip® Enhanced Stormwater Filtration System provides statistically significant
removal of TSS, dissolved copper, dissolved zinc, and total phosphorus from stormwater,
and can meet or exceed Ecology’s Basic, Enhanced, and Phosphorus treatment standards.
Ecology’s Recommendations:
Ecology should provide StormwateRx, LLC with the opportunity to demonstrate,
through field testing that follows an approved QAPP, whether the Aquip® Enhanced
Stormwater Filtration System can attain Ecology’s Basic, Enhanced, and Phosphorus
treatment performance levels.
Findings of Fact:
Based on paired grab sample data for TSS, from 14 installation sites, the Aquip®
Enhanced Stormwater Filtration System achieved the following treatment levels:
o Median effluent was 5 mg/L TSS, influent concentration in the range of 20-100
mg/L (n=32).
o Median percent removal was 98 percent, influent concentration in the range of
100-200 mg/L (n=8).
4
o Median percent removal was 98 percent, influent concentration greater than 200
mg/L (n=8).
Based on paired grab sample data for dissolved copper, from 7 installation sites, the
Aquip® Enhanced Stormwater Filtration System achieved the following treatment levels:
o Median percent removal was 73 percent, influent concentration in the range of
0.003-0.02 mg/L (n=5).
o Median percent removal was 93 percent, influent concentration greater than 0.02
mg/L (n=32).
Based on paired grab sample data for dissolved zinc, from eight installation sites, the
Aquip® Enhanced Stormwater Filtration System achieved the following treatment levels:
o Median percent removal was 59 percent, influent concentration in the range of
0.02-0.3 mg/L (n=30).
o Median percent removal was 94 percent, influent concentration greater than 0.3
mg/L (n=21).
Based on paired grab sample data for total phosphorus, from six installation sites, the
Aquip® Enhanced Stormwater Filtration System achieved the following treatment levels:
o Median percent removal was 60 percent, influent concentration in the range of
0.1-0.5 mg/L (n=14).
o Median percent removal was 89 percent, influent concentration greater than 0.5
mg/L (n=5).
Issues to be Addressed By the Company:
1. The Aquip® Enhanced Stormwater Filtration System must show that it can reliably attain the
minimum percent removal criteria for Basic, Enhanced, and Phosphorus treatment for runoff
found from local highways, parking lots, and other high-use areas at the design-operating rate
in accordance with the Ecology TAPE protocols. StormwateRx, LLC should test a variety of
operating rates to establish conservative design rates.
2. Test the system under normal operating conditions, such that pollutants partially fill the
system. Results obtained for “clean” systems may not be representative of typical
performance.
3. StormwateRx, LLC submitted extensive grab sample data from several sites operating in
industrial treatment settings. Pollutant concentrations are both within and above the ranges
required by TAPE. Testing to achieve a GULD under the TAPE program will need to focus
on pollutant concentrations within the specified TAPE ranges, as well as using flowweighted composite sampling (or other method approved in the QAPP) as opposed to grab
sampling.
4. Calculation of treatment efficiency shall be in accordance with the 2011 Revision of the
Guidance for Evaluating Emerging Stormwater Treatment Technologies: Technology
Assessment Protocol – Ecology (TAPE).
5
5. StormwateRx shall include a discussion of treatment efficiency (percent removed) as flow
rates change in the Technical Evaluation Report.
6. Conduct field-testing at sites that are indicative of the treatment goals.
7. Conduct testing to obtain information about maintenance requirements in order to come up
with a maintenance cycle.
8. Conduct loading tests on the filter media to determine maximum treatment life of the system.
