Purpose and Specific Narrative
. I
U
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.
J
'J
u
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 011 and grease on paved surfaces where
they easily wash off into streams.

1. Stormceptor Overview
J
The Stormceptor System is a water quality device used to remove total
suspended solids (T88) 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 8tormceptor System with precast
concrete components and a fiberglass disc insert.
LJ
u
2. Stormceptor System Operation
LJ
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 8tormceptor). 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 Techn;cal Manual.
J
LJ
u
L1
u
u
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
u
u
3. Identification of Stormceptor
u
Allin-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
u
LJ
LJ
u
u
unit, there still may be a question as to the size of the unjt. 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.
u
LJ
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.

Inspection and Reportino
Routine inspections are responsibility of the BMP owner and should be
performed at a minimum of every six months. Maintenance is also the
responsibility of the owner. The BMP owner shall be financially responsible for
any maintenance or repairs that may be required. The approved maintenance
plan and inspection forms provided with this manual should be used as guidance
for performing maintenance activities. Completed inspection forms must be
maintained by the BMP owner. Annual inspection reports are to be sent to the
City of Carmel. The first report is due one year after construction is completed,
with subsequent reports due each year within the same month of the initial
report. Ifthere are any deficiencies found during the inspection, these should be
addressed. If the inspection report is not received within the month it is due, if
there are deficiencies which were not included in the report, or if any deficiencies
included in the report are not addressed in a timely manner, the BMP owner
faces enforcement action from the City.
The City and/or its representatives have the right to enter the property to inspect
BMP's. In the event that the City finds a BMP in need of maintenance or repair,
the City will notify the BMP owner of the necessary maintenance or repairs and
give the landowner a timeframe for completing the maintenance or repairs. If the
maintenance or repairs are not completed within the timeframe, the City shall
perform the maintenance or repairs and bill the landowner for the actual costs for
the work.
STORMCEPTOR@ inspection & Maintenance Activities
Refer to the Owners manual and inspection checklist provided with this manual
for operation, maintenance and inspection of the STORMCEPTOR@ SQTU. The
checklist is for the use of the owner in performing routine inspections. The City
will perform annual inspections of the SQTU's, using a similar checklist. The
developer/owner is responsible for the cost of maintenance and annual
inspections. See Table A for a schedule of fees. The BMP owner must maintain
and update the BMP operations and maintenance plan. At a minimum, the
operations and maintenance plan must include, but is not limited to:
1. Inspection for any blockages or debris on insert disk
u
U
U
2. Inspection and maintenance procedure as called for in The Stormceptor
System Owners Manual.
BMP owners must routinely inspect SOTU's to verify that all SOTU components
are functioning as designed and are not in danger of failing. All SOTU's need
maintenance to function as water quality enhancements.

Slormceplor Overview
The StormcepLor 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 Stonnceptor System
with precast concrete components and a fiberglass disc insert. A fiberglass SLormceptor can also be
provided for special applications.
The Stormceptor System product line consists of four patented designs:
o
The In-Line (Conventional) Stormceptor, available in eight model sizes ranging from 900 to 7200
gallon storage capacity.
An In-Llne (Series) Stormceptor is available in three model sizes ranging from 11,000 to 16,000
gallon storage capacity.
The Submerged Stonnceptor, an in-line system designed for oil and sediment removal in partially
submerged pipes, available in all models sizes ranging from 450i to 16,000 gallon storage capacity.
The Inlet Stormceptor is a 450 gallon unit designed for small drainage areas.
o
D
o
Stormeeptor removes free oil and suspended solids from storm water preventing hazardous spills and
non-point source pollution from entering downstream lakes and rivers. Rinker Malerials and its
affiliates market 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 Caribbean since 1990.
o
o
D
o
o
o
u
o
In the Stormceptor, a fiberglass insert separates the treatment chamber from the by-pass chamber. The
different insert designs are illustrated in Figures I and 2. These designs are easily distinguishable
tram the surface once the cover has been removed.
There are fOllr 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 inleL pipe, the
drop pipe opening to the lower chamber, the weir, a 6" oil inspeetion/eleanoul pipe, a large 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
app /icatlons.
The STC ("eries) Stormceptors consist ofLwo chambers comprised of similar fiberglass inserts. These
units also contain a 6" oil/inspection cleanout pipe and 24" outlet riser pipes.
The submerged disc inserL 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/cleanout port.

Stormceotor Maintenance Guideline!.'
o
The perfom1ancc 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 perfonned \.vhen the sediment volume in the unit reaches 15% of the total storage.
This recommendation is based on several factors:
D
o
u
o
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 regular 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 appl ications; 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.
o
In the event of any hazardous material spi II, Rinker Materials recom mends mai ntenance be performed
immediately. Maintenance should be performed by a licensed liquid waste hauler. You should
also noti fy the appropriate regul atory agcnc ies as requ ired

4.1 Recommended Maintenance Procedure
For the "disc" design, oil is removed through the 6" inspeetion/cleanoutpipe 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 Stormccptor with a dipstick tube
equipped with a ball valve (Sludge Judge~'). It is recommended that maintenance be perfonned once
the sediment 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 Storrnceptor 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 inseli models. Any potential obstructions at the inlet can be observed from
the surface. The fj berglass inseli has been designed as a platform for authorized maintenance
personnel in the event that an obstruction needs to be removed.
[J
o
Typically, maintenance is performed by the Vacuum Service Industry, a well established sector
of the service industry that cleans underground tanks, sewers, and catch-basi ns. Costs to clean
a Stormceptor wil] 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

u
u
The requirements tor the disposal of material from Stormceptor are similar to that of any other Best
Managemcnt Practices (BMP). Local guidelines should be consulted prior to disposal of the separator
contents. The material may NOT be dumped into a sanitary sewer.
J
In most areas the sediment, once de\vatered, can be d lsposed of in a sani tary landfi II. Jt is not
anticipated that the sediment would be classitied as hazardous waste. Tn all
o
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.
u
u
What if] see an oil rainbow or sheen at the Stormceptor outlet?
u
u
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 pplll). Stormceptor will remove over 95% of all free oil and the appearance ofa 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 Stomlceptor will not be able to
remove it. The Stormceptor is designed for free oil removal and not emulsified or dissolved oil
conditions.
o
5.0 Recommended Safety Procedures
U..
, .
Rinker Materials strongly recommends that any person who enters a Storrnceptor System follow
all appHcable OSHA regulations for entry in permit required confined spaces, as outlined in
29 CFR 1910.]46. A permit required confined space consists ofa space that:
u
u
u
Is large enough and so configured that an employee can bodi ly enter and perform assigned work.
Has limited or restricted means for entry and exit.
Is not designed tor continuous employee occupancy.
Contains or has one of the following:
- a potential to contain a hazardous atmosphere.
- a material that has the potential for engulfing an entrant.
- any other rel:ognized serious safety hazard.
[J
Storm water and wastewater systems fall under OSIIA guidelines tor a permit required confined
space. Failure to follow OSHA guidelines for entry and work in a permit required confined
space can result in seriolls inj ury or death. Please exercise extreme caution and follow appropriate
safety procedures when entering any confined space.
u
Two square pick holes in the cover vent the Stormceptor, allow for removal of the cover, and provide
sampling pOlts 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.
