BMP Inspection and Maintenance:
Routine inspections are the responsibility of the BMP owner. Maintenance is also the
responsibility of the owner. Sediment removal shall be necessary every 6 months to 1
year. The City of Carmel’s Engineering Office must be notified of any changes in BMP
ownership, major repairs, or BMP failures in writing within 30 days. The letter should be
addressed to:
City of Carmel Engineering Department
One Civic Square, 1st Floor
Carmel, IN 46032
In the event that the City of Carmel’s Engineering Office finds a BMP in need of
maintenance or repair, the City of Carmel’s Engineering Office 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 designated time frame, the City shall perform the repairs or maintenance and
bill the landowner for the actual cost of the work.
The City of Carmel’s Engineering Office representatives have the right to enter the
property to inspect the BMP.

III. BMP and Maintenance Information
BMP 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, floatables, 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.
With this in mind, non-coal tar based sealants must be used if needed during
the asphalt resurfacing and sealing.
Best management practices (BMP’s), both structural and non-structural, can reduce
the pollutants in stormwater. Specifically, two hydrodynamic separators will treat
stormwater flowing through the system. And a second in-line BMP will be an Aquatic
Shelf added to the existing detention pond, which will help filter the stormwater.
The higher-tech method for treating stormwater involves the mechanical device
known as a hydro-dynamic separator. The Hydro-dynamic separator that we are
recommending is an Aqua-Swirl™ (see attached product information). This BMP is a
combination area inlet/manhole containing specialized internal separation and
filtering components to treat the incoming storm water by removing suspended
solids. The site has fairly strict space limitations; the Aqua-Swirl™ is a perfect fit
The Aquatic Shelf is a low-tech method which takes advantage of the natural ability
of plant materials to filter pollutants. The plants installed within the constructed
wetland remove sediment, Biochemical Oxygen Demand (BOD), organic nutrients,
and trace metals from stormwater runoff. This is accomplished by slowing down
stormwater using an in-line permanent pool or pond affecting settling of pollutants.
The Aquatic Shelf area willl be protected from spraying and mowing. Signage will be
posted around the top of the shelf which prohibits spraying and mowing.
Inspections
Responsibilities:
Stormwater quality facilities shall be maintained in good condition, in accordance
with the Operation and Maintenance procedures and schedules listed in the
Indiana Stormwater Quality Manual or the City of Carmel Stormwater Technical
Standards Manual, and the terms and conditions of the approved stormwater
permit, and shall not be subsequently altered, revised, or replaced except in
accordance with the approved stormwater permit, or in accordance with
approved amendments or revisions in the permit. Following construction
completion, inspection and maintenance of stormwater quality facilities shall be
the long-term responsibility of the Owner.
The City of Carmel Engineering department and/or the Hamilton County
Surveyor’s Office has the authority to perform long-term, post-construction
inspection of all public or privately owned stormwater quality facilities. The
inspections will follow the Operation and Maintenance procedures included in the
City of Carmel Stormwater Technical Standards Manual and/or permit application
for each specific BMP. The inspection will cover physical conditions, available
water quality storage capacity and the operational condition of key facility
elements. Noted deficiencies and recommended corrective action will be
included in an inspection report.
The Owner shall submit an annual BMP Maintenance Report to the City of
Carmel Engineering Department. 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. If there are any deficiencies found during the
inspections, 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. This report
should be submitted to:

Aqua-Swirl™ Concentrator
Stormwater Treatment System
Inspection and Maintenance
The Aqua-Swirl™ Concentrator Stormwater
Treatment System has been designed to minimize and
simplify inspection/maintenance procedures. It is
important that a routine inspection and maintenance
program is established for each unit based on the
volume or load of the contaminants of concern, the
frequency of releases of contaminants at the facility or
location, and the nature of the area being drained.
In most cases, AquaShield™, Inc. recommends that
for the first year of operation, quarterly inspection of
the Aqua-Filter™ be performed in order to develop an
appropriate schedule of maintenance for the site
(typically, semi-annual or annual cleanout is required
in colder climates where street sanding occurs). We
have included a sample inspection worksheet and
inspection/maintenance log for your use.
Figure 1: Seattle, WA – Aqua-Swirl™
Installed Above Ground
Figure 2: Aqua-Swirl™ Stormwater Treatment
System
Based upon experience from the system’s first year
in operation, we recommend the inspection
schedule be revised to reflect the site-specific
conditions encountered. Again, typically the
inspection schedule for subsequent years is reduced
to semi-annual inspection.
Aqua-Swirl™ Inspection and Cleanout Procedure
Clean out of the Aqua-Swirl™ is simple. The chamber can be
inspected and maintained completely from the surface (see Figure
3). Free-floating oil and floatable debris can be directly observed
and removed through the 28” service access provided.
Cleanout of accumulated sediment only needs to be performed
when the usable sediment storage volume has been occupied.
Specifically, when the sediment pile is within 24” of the water
surface, the system should be vactored clean (see Figure 4).
Sediment depths can easily be determined by lowering a measuring
device (i.e. stadia rod) to the top of the sediment pile and to the
water’s surface.
Figure 3: Measuring Sediment Build-Up
Figure 4: Vactoring Aqua-Filter™
System
A vactor truck can be used to remove the accumulated sediment and
debris. Disposal of the material is typically treated in the same
fashion as catch basin cleanouts. The sediment can be recycled as
loose fill material, recycled at an asphalt plant or brick kiln, or used
as cover for municipal landfills.

Routine Maintenance:
The BMP owner will also be required to perform any maintenance specified at the
City’s discretion. The following criteria shall be considered the minimum routine
maintenance to be performed:
1. The detention area and drainage inlet/outlet structures should be kept free of
debris and litter.
2. Removal of invasive vegetation from all side slopes. Chemical lawn treatment
should be avoided near the pond embankments. Maintenance will also be
required to repair erosion (if present) in the detention basin area.
3. Removal of sediment accumulation from the detention basin. Detention basin
sediment removal should occur when sediment depths reach 1 foot or 50 percent
of the pond volume below normal pool.
4. Removal of woody vegetation from the embankment.
5. No spraying or mowing should occur near the normal pool or within the area of
the aquatic shelf of the wet pond.
Remedial Maintenance:
Remedial maintenance shall occur whenever deemed necessary either by the BMP owner
or the City of Carmel Engineering Department.
Statements and Responsibilities
The City of Carmel Engineering Department representatives have the right to enter
