BMP -Best Management Practices, refer to structural or non-structural
measures designed for the benefit of water quality and quantity.
' BMP owner -The owner of the BMP, typically the property owner. The BMP
owner may also be the lessee of the property in the case of Ibng-term leases of
commercial and industrial zoned properties. The lessee is considered the bmp
owner only if the lease specifically states that construction by the lessee must
meet applicable local codes and regulations.
' SQTU -Stormwater Quality Treatment Unit, a structural BMP designed to
provide 80%TSS removal of the runoff of a 1-inch storm event.
' STORMCEPTOR~ -The specific SQTU being utilized on this site.
Purpose and Specific Narrative
' Urban Stormwater runoff contains many types and forms of pollutants. When
compared to Stormwater run-off from pre-developed conditions, high
concentrations and some contaminates that are not naturally present in surface
' runoff from undeveloped local lands are found. Runoff from undeveloped
watersheds contains sediment particles, oxygen-demanding compounds,
nutrients, metals, and other constituents. Once developed, constituent loads
increase because surface runoff volumes increase and the sources of many of
these pollutants also increase. Supplemental applications of compounds, such
as fertilizers, also tend to increase the availability of some pollutants to
' stormwater runoff.
Runoff water quality in urban areas can be extremely detrimental to local habitat.
' Paved surfaces and standing water bodies for stormwater management control
elevate the temperature of water entering streams. Chemicals in standing water
and ponds are oxidized, resulting in depressed levels of dissolved oxygen.
' Increased runoff volumes and rates create scour and deposition damage to in
stream habitat. Activities in urbanized areas, such as vehicular traffic, deposit
pollutants such as heavy metals and oil and grease on paved surfaces where
' they easily wash off into streams.
Best management practices (BMP's), both structural and non-structural, can
' reduce the pollutants in stormwater.
The BMP for this site is the STORMCEPTOR~ SQTU.
t 1. Stormceptor Overview
The Stormceptor System is a water quality device used to remove total
' suspended solids (TSS) and free oil (TPH) from storm water run-off. Stormceptor

takes the place of a conventional manhole or inlet structure within a storm drain
system. Rinker Materials manufactures the Stormceptor System with precast
concrete components and a fiberglass disc insert.
2. Stormceptor System Operation
The Stormceptor consists of a lower treatment chamber, which is always full of
water, and a by-pass chamber. Storm water flows into the by-pass chamber via
the storm sewer pipe or grated inlet (Inlet Stormceptor). Normal flows are
diverted by a weir and drop arrangement into a treatment chamber. Water flows
up through the submerged outlet pipe based on the head at the inlet weir and is
discharged back into the by-pass chamber downstream of the weir. The
downstream section of the pipe is connected to the outlet sewer pipe. Oil and
other liquids with a specific gravity less than water rise in the treatment chamber
and become trapped under the fiberglass weir. Sediment will settle to the bottom
of the chamber by gravity. The circular design of the treatment chamber is critical
to prevent turbulent eddy currents and to promote settling. During infrequent
high flow conditions, storm water will by-pass the weir and be conveyed to the
outlet sewer directly. The by-pass is an integral part of the Stormceptor since
other oil/grit separators have been noted to scour during high flow conditions
(Schueler and Shepp, 1993). For further details please refer to The Stormceptor
System Technical Manual.
The key benefits of Stormceptor include:
• Capable of removing more than 80% of the total sediment load when properly
applied as a source control for small drainage areas
• Removes free oil from storm water during normal flow conditions
• Will not scour or resuspend trapped pollutants
• Ideal spill control device for commercial and industrial developments
• Vertical orientation facilitates maintenance and inspections
3. Identification of Stormceptor
All In-Line (including Submerged) Stormceptors are provided with their own
frame and cover. The cover has the name STORMCEPTOR clearly embossed
on it to allow easy identification of the unit. The name Stormceptor is not
embossed on the inlet models due to the variability of inlet grates used/approved
across North America. You will be able to identify the Inlet Stormceptor by
looking into the grate since the insert will be visible. Once you have located a
unit, there still may be a question as to the size of the unit. Comparing the
measured depth from the water level (bottom of insert) to the bottom of the tank
with Table 1 should help determine the size of the unit.
The SQTU owner will need to provide inspection and maintenance for the
STORMCEPTOR~ Units. Please refer to the STORMCEPTOR® System
Owners Manual and Inspection/Maintenance checklists for detailed descriptions
' of the maintenance requirements for the Stormceptor system.

Thank You!
We want to thank you for selecting the Stormceptor System to use in your efforts in protecting the
environment. Stormceptor is one of the most effective and maintenance friendly storm water quality
treatment devices available. If you have any questions regarding the operation and maintenance of the
Stormceptor System, please call your local Rinker Materials representative, or the Stormceptor
Information Line at (800) 909-7763.
1. Stormceptor Overview
' The Stormceptor System is a water quality device used to remove total suspended solids (TSS) and
free oil (TPIT) from storm water run-off. Stormceptor takes the place of a conventional manhole or
inlet structure within a storm drain system. Rinker Materials manufactures the Stormceptor System
' with precast concrete components and a fiberglass disc insert. A fiberglass Stormceptor can also be
provided for special applications.
' The Stormceptor System product line consists of four patented designs:
The In-Line (Conventional) Stormceptor, available in eight model sizes ranging from 900 to 7200
gallon storage capacity.
t An In-Line (Series) Stormceptor is available in three model sizes ranging from 11,000 to 16,000
gallon storage capacity.
• The Submerged Stormceptor, an in-line system designed for oil and sediment removal in partially
submerged pipes, available in all models sizes ranging from 4SOi to 16,000 gallon storage capacity.
• The Inlet Stormceptor is a 450 gallon unit designed for small drainage areas.
' Stormceptor removes free oil and suspended solids from storm water preventing hazardous spills and
non-point source pollution from entering downstream lakes and rivers. Rinker Materials and its
affiliates mazket and manufacture the Stormceptor System in the United States and Australia. Several
thousand Stormceptor Systems have been installed in various locations throughout North America,
Australia and the Cazibbean since 1990.
In the Stormceptor, a fiberglass insert separates the treatment chamber from the by-pass chamber. The
different insert designs aze illustrated in Figures 1 and 2. These designs are easily distinguishable
from the surface once the cover has been removed.
' There aze four versions of the in-line disc insert: single inlet/outlet, multiple inlet, in-line series insert
and submerged designs. In the non-submerged "disc" design you will be able to see the inlet pipe, the
' drop pipe opening to the lower chamber, the weir, a 6" oil inspection/cleanoutpipe, alarge 24" riser
pipe opening offset on the outlet side of the structure, and the outlet pipe from the unit. The weir
will be around the 24" outlet pipe on the multiple inlet disc insert and on large diameter pipe
' applications.
The STC (series) Stormceptors consist of two chambers comprised of similar fiberglass inserts. These
t units also contain a 6" oillinspection cleanout pipe and 24" outlet riser pipes.
The submerged disc insert has a higher weir and a second inlet drop pipe. In the inlet design you
will be able to see an inlet drop pipe and an outlet riser pipe as well as a central oil
' inspection/cleanouYpnrt.

' The performance of all storm water quality measures that rely on sedimentation decreases as they fill
with sediment (See Table 2 for Stormceptor capacities). An estimate of performance loss can be made
from the relationship between performance and storage volume. Rinker Materials recommends
' maintenance be performed when the sediment volume in the unit reaches 15% of the total storage.
This recommendation is based on several factors:
Sediment removal is easier when removed on a regular basis (as sediment builds up it compacts
and solidifies making maintenance more difficult).
Development of a routine maintenance interval helps ensure a regulaz maintenance schedule is
followed. Although the frequency of maintenance will depend on site conditions, it is estimated
that annual maintenance will be required for most applications; annual, maintenance is a routine
occurrence which is easy to plan for and remember.
A minimal performance degradation due to sediment build-up can occur.
In the event of any hazazdous material spill, Rinker Materials recommends maintenance be performed
immediately. Maintenance should be performed by a licensed liquid waste hau]er. You should
also notify the appropriate regulatory agencies as required.

4.1 Recommended Maintenance Procedure
s
For the "disc" design, oil is removed through the 6" inspection/cleanoutplpe and sediment is removed
through the 24" diameter outlet riser pipe. Alternatively, oil could be removed from the 24" opening if
water is removed from the treatment chamber, lowering the oil level below the drop pipes.
The depth of sediment can be measured from the surface of the Stormceptor with a dipstick tube
equipped with a ball valve (Sludge Judge"). It is recommended that maintenance be performed once
the sedunent depth exceeds the guideline values provided in Table 3 for the reasons noted in Section 4
Stormceptor Maintenance Guidelines.

' No entry into the unit is required for routine maintenance of the Inlet Stormceptor or the smaller disc
insert models of the In-Line Stormceptor. Entry to the level of the disc insert may be required for
servicing the larger disc insert models. Any potential obstructions at the inlet can be observed from
' the surface. The fiberglass insert has been designed as a platform for authorized maintenance
personnel in the event that an obstruction needs to be removed.
' Typically, maintenance is performed by the Vacuum Service Industry, a well established sector
of the service industry that cleans underground tanks, sewers, and catch-basins. Costs to clean
a Stormceptor will vary based on the size of the unit and transportation distances. If you need
assistance for cleaning a Stormceptor unit, contact your local Rinker Materials representative, or the
Stormceptor Information Line at (800) 909-7763.

4.2 Disposal of Trapped Material from Stormceptor
The requirements for the disposal of material from Stormceptor are similar to that of any other Best
Management Practices (BMP). Local guidelines should be consulted prior to disposal of the separator
contents. The material may NOT be dumped into a sanitary sewer.
In most azeas the sediment, once dewatered, can be disposed bf in a sanitary landfill. It is not
anticipated that the sediment would be classified as hazardous waste. In all
disposal options, approval from the disposal facility operator/agency is required. Petroleum waste
products collected in Stormceptor (oil/chemical/fuel spills) should be removed by a licensed waste
management company.
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 rainbow or sheen can be seen at very small oil concen-
trations (< 10 ppm). Stormceptor will remove over 95% of all 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 oil 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.
' S.0 Recommended Safett~ Procedures
Rinker Materials strongly recommends that any person who enters a Stormceptor System follow
' all applicable OSHA regulations for entry in permit required confined spaces, as outlined in
29 CFR 1910.146. A permit required confined space consists of a space that:
1
1
• Is large enough and so configured that an employee can bodily enter and perform assigned work.
• Has limited or restricted means for entry and exit.
• Is not designed for continuous employee occupancy.
• Contains or has one of the following:
- a potential to contain a hazardous atmosphere.
- a material that has the potential for engulfmg an entrant.
- any other recognized serious safety hazard.
Storm water and wastewater systems fall under OSHA guidelines for a permit required confined
space. Failure to follow OSHA guidelines for entry and work in a permit required confined
space can result in serious injury or death. Please exercise extreme caution and follow appropriate
safeTy procedures when entering any confined space.
Two square pick holes in the cover vent the Stormceptor, allow for removal of the cover, and provide
sampling ports for air quality monitoring before the cover is removed. If you must enter the
Stormceptor, please note that if the disc insert inside is wet, it can be slippery.

Recognizing that every work site is different, the responsibility for safety falls on the contractor. The
contractor must ensure that all employees and subcontractors follow established safet)~ procedures and
OSHA regulations for working in and around permit required confined spaces as well as for any other
safety hazard that may be present on that particular site.
