Re: Mansions at Marine Cheek Stormwater Facility Maintenance Agreement
City of Fort Worth, Tarrant County, Texas
To Whom it May Concern,
This document is a supplemental form for the Stoimwater Facility Maintenance
Agreement Exhibit C. Due to the nature of the design constraints, a water quality device
will be installed with a maintenance invert in excess of 25'. Per Exhibit B of this
document, it is required by the City of Fort Worth that additional approval will be
required to show that maintenance can be performed in a practical manor. It has been
determined by HPCivil that specialized heavy duty equipment will be needed, and is
available,to perform such maintenance. Refer to Exhibit E (this document) for an
example proposal that details out the type of heavy duty equipment needed to perform
maintenance. The equipment mentioned in Exhibit E of this document, or equivalent,
will be the base requirement for maintaining this Water Quality Device containing a
maintenance invert greater than 25'.
Please feel free to contact us if you have any questions

Congratulations!
Your selection of a Stormceptor® means that you have chosen the most recognized and efficient
stormwater oil/sediment separator available for protecting the environment. Stormceptor is a
pollution control device often referred to as a "Hydrodynamic Separator (HDS)" or an "Oil Grit
Separator (OGS)", engineered to remove and retain pollutants from stormwater runoff to protect
our lakes, rivers and streams from the harmful effects of non-point source pollution.
1 —Stormceptor Overview
Stormceptor is a patented stormwater quality structure most often utilized as a treatment
component of the underground storm drain network for stormwater pollution prevention.
Stormceptor is designed to remove sediment, total suspended solids (TSS), other pollutants
attached to sediment, hydrocarbons and free oil from stormwater runoff. Collectively the
Stormceptor provides spill protection and prevents non-point source pollution from entering
downstream waterways.
Key benefits of Stormceptor include:
• Removes sediment, suspended solids, debris, nutrients, heavy metals, and hydrocarbons (oil
and grease) from runoff and snowmelt.
• Will not scour or re-suspend trapped pollutants.
• Provides sediment and oil storage.
• Provides spill control for accidents, commercial and industrial developments.
• Easy to inspect and maintain (vacuum truck).
• "STORMCEPTOR" is clearly marked on the access cover (excluding inlet designs).
• Relatively small footprint.
• 3rd Party tested and independently verified.
• Dedicated team of experts available to provide support.
Model Types:
r' C {gtan ar
• EOS (Extended Oil Storage)
• OSR (Oil and Sand Removal)
• MAX (Custom designed unit, specific to site)
Configuration Types:
• Inlet unit (accommodates inlet flow entry, and multi-pipe entry)
•
In-Line (accommodates multi-pipe entry)

technology.
Stormceptor creates a non-turbulent treatment environment below the insert platform within the
system. The insert diverts water into the lower chamber, allowing free oils and debris to rise, and
sediment to settle under relatively low velocity conditions. These pollutants are trapped and stored
below the insert and protected from large runoff events for later removal during the maintenance
procedure.
With thousands of units operating worldwide, Stormceptor delivers reliable protection every day,
in every storm. The patented Stormceptor design prohibits the scour and release of captured
pollutants, ensuring superior water quality treatment and protection during even the most extreme
storm events. Stormceptor's proven performance is backed by the longest record of lab and field
verification in the industry.

3 ---Stormceptor Identification
Stormceptor is available in both precast concrete and fiberglass vessels, with precast concrete
often being the dominant material of construction.
In the Stormceptor, a patented, engineered fiberglass insert separates the structure into an upper
chamber and lower chamber, The lower chamber will remain full of water, as this is where the
pollutants are sequestered for later removal. Multiple Stormceptor model (STC, OSR, EOS and
MAX) configurations exist, each to be inspected and maintained in a similar fashion.
Each unit is easily identifiable as a Stormceptor by the trade name "Stormceptor" embossed
on each access cover at the surface. To determine the location of"inlet" Stormceptor units with
horizontal catch basin inlet, look down into the grate as the Stormceptor insert will be visible. The
name "Stormceptor" is not embossed on inlet models due to the variability of inlet grates used/
approved across North America.
6 Stormceptor®Owner's Manual Rinker Materials
Once the location of the Stormceptor is determined, the model number may be identified by
comparing the measured depth from the fiberglass insert level at the outlet pipe's invert (water
level) to the bottom of the tank using Table 1.
In addition, starting in 1996 a metal serial number tag containing the model number has been
affixed to the inside of the unit, on the fiberglass insert. If the unit does not have a serial number,
or if there is any uncertainty regarding the size of the unit using depth measurements, please
contact your local Rinker Materials Representative for assistance.
Sizes/Models
Typical general dimensions and capacities of the standard precast STC, EOS & OSR Stormceptor
models are provided in Tables 1 and 2, Typical rim to invert measurements are provided later
in this document. The total depth for cleaning will be the sum of the depth from outlet pipe invert
(generally the water level) to rim (grade) and the depth from outlet pipe invert to the precast
bottom of the unit. Note that depths and capacities may vary slightly between regions.

4-- Stormceptor Inspection & Maintenance
Regular inspection and maintenance is a proven, cost-effective way to maximize water resource
protection for all stormwater pollution control practices, and is required to insure proper functioning
of the Stormceptor. Both inspection and maintenance of the Stormceptor is easily performed from
the surface. Stormceptor's patented technology has no moving parts, simplifying the inspection
and maintenance process.
Please refer to the following information and guidelines before.conducting inspection and
maintenance activities.
When is inspection needed?
• Post-construction inspection is required prior to putting the Stormceptor into service.
• Routine inspections are recommended during the first year of operation to accurately assess
the sediment accumulation.
• Inspection frequency in subsequent years is based on the maintenance plan developed in
the first year.
• Inspections should also be performed immediately after oil, fuel, or other chemical spills,
When is maintenance cleaning needed?
• For optimum performance, the unit should be cleaned out once the sediment depth reaches
the recommended maintenance sediment depth, which is approximately 15% of the unit's
total storage capacity (see Table 3). The frequency should be adjusted based on historical
inspection results due to variable site pollutant loading.
• Sediment removal is easier when removed on a regular basis at or prior to the recommended
maintenance sediment depths, as sediment build-up can compact making removal more
difficult.
• The unit should be cleaned out immediately after an oil, fuel or chemical spill,
What conditions can compromise Stormceptor performance?
• If construction sediment and debris is not removed prior to activating the Stormceptor unit,
maintenance frequency may be reduced.
• If the system is not maintained regularly and fills with sediment and debris beyond the
capacity as indicated in Table 2, pollutant removal efficiency may be reduced.
• If an oil spill(s) exceeds the oil capacity of the system, subsequent spills may not be
captured.
• If debris clogs the inlet of the system, removal efficiency of sediment and hydrocarbons may
be reduced.
• if a downstream blockage occurs, a backwater condition may occur for the Stormceptor and
removal efficiency of sediment and hydrocarbons may be reduced.
What training is required?
The Stormceptor is to be inspected and maintained by professional vacuum cleaning service
providers with experience in the maintenance of underground tanks, sewers and catch basins.
For typical inspection and maintenance activities, no specific supplemental training is required
Kinker Materials Stormceptor°owner's Manual 9
for the Stormceptor. Information provided within this Manual (provided to the site owner) contains
sufficient guidance to maintain the system properly.
In unusual circumstances, such as if a damaged component needs replacement or some other
condition requires manned entry into the vessel, confined space entry procedures must be
followed. Only professional maintenance service providers trained in these procedures should
enter the vessel. Service provider companies typically have personnel who are trained and
certified in confined space entry procedures according to local, state, and federal standards.
What equipment is typically required for inspection?
• Manhole access cover lifting tool
• Oil dipstick/ Sediment probe with ball valve (typically%-inch to 1-inch diameter)
• Flashlight
• Camera
• Data log / Inspection Report
• Safety cones and caution tape
• Hard hat, safety shoes, safety glasses, and chemical-resistant gloves
10 Stormceptor®Owner's Manual Rinker Materials
Recommended Stormceptor Inspection Procedure:
• Stormceptor is to be inspected from grade through a standard surface manhole access
cover.
• Sediment and oil depth inspections are performed with a sediment probe and oil dipstick.
• Oil depth is measured through the oil inspection port, either a 4-inch or 6-inch diameter port.
• Sediment depth can be measured through the oil inspection port or the 24-inch diameter
outlet riser pipe.
• Inspections also involve a visual inspection of the internal components of the system.

Recommended Stormceptor Maintenance Procedure
Maintenance of Stormceptor is performed using a vacuum truck.
No entry into the unit is required for maintenance. DO NOT ENTER THE STORMCEPTOR
CHAMBER unless you have the proper personal safety equipment, have been trained and
are qualified to enter a confined space, as identified by local Occupational Safety and Health
Regulations (e.g. 29 CFR 1910.146). Without the proper equipment, training and permit, entry into
confined spaces can result in serious bodily harm and potentially death. Consult local and/or state
regulations to determine the requirements for confined space entry. Be aware, and take precaution
that the Stormceptor fiberglass insert may be slippery. In addition, be aware that some units do not
have a safety grate to cover the outlet riser pipe that leads to the submerged, lower chamber.
• Ideally maintenance should be conducted during dry weather conditions when no flow is
entering the unit.
• Stormceptor is to be maintained through a standard surface manhole access cover.
• Insert the oil dipstick into the oil inspection port. If oil is present, pump off the oil layer into
separate containment using a small pump and tubing.
• Maintenance cleaning of accumulated sediment is performed with a vacuum truck.
• For 6-ft diameter models and larger, the vacuum hose is inserted into the lower
chamber via the 24-inch outlet riser pipe (See Fig. 5).
• For 4-ft diameter model, the removable drop tee is lifted out, and the vacuum hose is
inserted into the lower chamber via the 12-inch drop tee hole (See Fig. 6).
Figure 5. Figure 6.

• Using the vacuum hose, decant the water from the lower chamber into a separate
containment tank or to the sanitary sewer, if permitted by the local regulating authority.
• Remove the sediment sludge from the bottom of the unit using the vacuum hose. For large
Stormceptor units, a flexible hose is often connected to the primary vacuum line for ease of
movement in the lower chamber.
• Units that have not been maintained regularly, have surpassed the maximum recommended
sediment capacity, or contain damaged components may require manned entry by trained
personnel using safe and proper confined space entry procedures.

What is required for proper disposal?
The requirements for the disposal of material removed from Stormceptor units are similar to that
of any other stormwater treatment Best Management Practices (BMP). Local guidelines should be
consulted prior to disposal of the separator contents. In most areas the sediment, once dewatered,
can be disposed of in a sanitary landfill. It is not anticipated that the sediment would be classified
as hazardous waste. This could be site and pollutant dependent. In some cases, approval from
the disposal facility operator/agency may be required.
What about oil spills?
Stormceptor is often implemented in areas where there is high potential for oil, fuel or other
hydrocarbon or chemical spills. Stormceptor units should be cleaned immediately after a spill
occurs by a licensed liquid waste hauler. You should also notify the appropriate regulatory
agencies as required in the event of a spill.
What if I see an oil rainbow or sheen at the Stormceptor outlet?
With a steady influx of water with high concentrations of oil, a sheen may be noticeable at the
Stormceptor outlet. This may occur because a hydrocarbon rainbow or sheen can be seen at
Rinker Materials Stormceptor®Owner's Manual 13
very small oil concentrations (< 10 ppm). Stormceptor is effective at removing 95% of free oil,
and the appearance of a sheen at the outlet with high influent oil concentrations does not mean
that the unit is not working to this level of removal. In addition, if the influent ail is emulsified, the
Stormceptor will not be able to remove it. The Stormceptor is designed for free oil removal and not
emulsified or dissolved oil conditions.
What factors affect the costs involved with inspection/maintenance?
The Vacuum Service Industry for stormwater drainage and sewer systems is a well-established
sector of the service industry that cleans underground tanks, sewers and catch basins. Costs
to clean Stormceptor units will vary. Inspection and maintenance costs are most often based on
unit size, the number of units on a site, sediment/oil/hazardous material loads, transportation
distances, tipping fees, disposal requirements and other local regulations.
What factors predict maintenance frequency?
Maintenance frequency will vary with the amount of pollution on your site (number of hydrocarbon
spills, amount of sediment, site activity and use, etc.). It is recommended that the frequency of
maintenance be increased or reduced based on local conditions. If the sediment load is high from
an unstable site or sediment loads transported from upstream catchments, maintenance may be
required semiannually. Conversely once a site has stabilized, maintenance may be required less
frequently (for example: two to seven year, site and situation dependent). Maintenance should be
performed immediately after an oil spill or once the sediment depth in Stormceptor reaches the
value specified in Table 3 based on the unit size.

Replacement parts
Since there are no moving parts during operation in a Stormceptor, broken, damaged, or
worn parts are not typically encountered. Therefore, inspection and maintenance activities are
generally focused on pollutant removal. However, if replacements parts are necessary, they
may be purchased by contacting your local Rinker Materials Representative or the Stormceptor
Information Line at {800} 909-7763.
The benefits of regular inspection and maintenance are many--from ensuring maximum
operation efficiency, to keeping maintenance costs low, to the continued protection of
natural waterways --and provide the key to Stormceptor's long and effective service life.

Particle Size Distribution
Removing silt particles from runoff ensures that the majority of the pollutants, such as hydrocarbons and heavy
metals that adhere to fine particles, are not discharged into our natural water courses. The table below lists the
particle size distribution used to define the annual TSS removal.

Stormceptor Design Notes
• Stormceptor performance estimates are based on simulations using PCSWMM for Stormceptor.
• Design estimates listed are only representative of specific project requirements based on total suspended solids
(TSS)removal,
• Only the STC 450i is adaptable to function with a catch basin inlet and/or inline pipes.
• Only the Stormceptor models STC 4501 to STC 7200 may accommodate multiple inlet pipes.
• Inlet and outlet invert elevation differences are as follows;
Inlet and Outlet Pipe Invert Elevations Differences
Inlet Pipe Configuration STC 450i STC 900 to STC STC 11000 to
7200 STC 16000
Single inlet pipe 3 in. 1 in. 3 in.
Multiple inlet pipes 3 in. 3 in. Only one inlet
pipe.
• Design estimates are based on stable site conditions only, after construction is completed.
• Design estimates assume that the storm drain is not submerged during zero flows. For submerged
applications,please contact your local Stormceptor representative.
• Design estimates may be modified for specific spills controls. Please contact your local Stormceptor
representative for further assistance.
