SECTION 3
OWNER -REQUIRED PERIODIC INSPECTIONS AND INSPECTIONS TO BE PERFORMED BY CITY
REPRESENTATIVES AND DPW DEFINITIONS
BMP Best management practices can refer to structural measures
(Wetlands, ponds, sand filters, etc.) or non-structural measures (restrictive
zoning, reduced impervious areas, etc.). BMPs are designed for the benefit of
water quality and quantity. For the purposes of this chapter, BMPs refer to
structural water quality BMPs.
BMP owner The owner of the BMP, typically the property owner. The BMP owner may also
be the leasee of property in the case of long-term leases of commercial or
industrial zoned properties. The leasee is considered the BMP owner only if the
lease specifically states that construction by the leasee must meet applicable
local codes and regulations.
BOD Biochemical oxygen demand
Contributing Contributing drainage area refers to the total drainage area
Drainage damage to a given point, including offsite drainage.
Effective drainage Effective drainage area refers to the drainage area from a
area specific site, excluding offsite drainage, where offsite drainage either does not
exist or where offsite drainage bypasses the site through culverts or other
means.
Impervious area Impervious areas are areas where the land surface has been altered to
decrease the amount of rainwater infiltration. Impervious surfaces include
paved roads, concrete driveways and rooftops.
Offline structure Offline structures are BMPs that treat only the water quality volume (WQv).
Flows exceeding the WQv bypass the structure and re-enter the watercourse
below the BMP.
Redevelopment Redevelopment means any construction, alteration, or improvement where
structures are removed and/or replaced. Where the disturbance caused by
redevelopment activities disturbs less than 0.5 acres, no water quality BMP
plan shall be required. Staff has the discretion to exempt the redevelopment
activities disturbing up to 5% more area.
Stormwater A system of vegetative, structural, and other measures
Quality that reduce or eliminate pollutants that might otherwise
Management be carried by surface runoff.
Total P Total Phosphorus
Total N Total nitrogen.
TSS Total suspended solids.
Treatment train A treatment train consists of more than one BMP in series treating stormwater
runoff. Such configurations are necessary when BMPs individually cannot meet
the 80%TSS reduction goal.
Watershed Watershed refers to the total drainage area contributing
runoff to a single point.
Purpose/Background Urban stormwater runoff contains many types and forms of pollutants. When
compared to stormwater runoff from pre -development conditions, higher
concentrations and some contaminants that are not naturally present in surface
runoff from undeveloped local lands are found. Runoff from 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 the streams. All roadway
construction and improvement projects that disturb more than % acre must
meet the requirements of this chapter.
Best management practices (BMPs), both structural and non-structural, can
reduce the amount of pollutants in stormwater. This section of the manual
establishes minimum standards for the design, maintenance, application, and
construction of water quality BMPs. The information provided in this chapter
establishes performance criteria for stormwater quality management and
procedures to be followed when preparing a BMP plan for compliance.
BMPs noted in this manual refer to post -construction BMPs, installed after
construction has been completed and the site has been stabilized. Installing
certain BMPs such as bioretention areas and sand filters, prior to stabilization
can cause failure of the measure due to clogging from sediment. However, with
a strict construction sequence, detention ponds and other BMPs can be
installed initially during construction and used as sediment control measures. In
those instances, the construction sequence must require that the pond be
cleaned out with pertinent elevations and storage and treatment capacities
reestablished as noted in the approved stormwater management plan.
SECTION 4
ROUTINE MAINTENANCE BY THE OWNER
WET POND
DESCRIPTION: The material presented in this fact sheet is intended to apply to this case where a wet
pond is being utilized as a post -construction stormwater quality BMP only. The pond has been designed
as a multi -purpose facility acting both as a water quality BMP and a wet -bottom detention pond. The
wet pond is a facility which removes 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 wet pond is similar to a dry pond,
except that a permanent volume of water is incorporated into the design.. Biological processes
occurring in the permanent pond pool aid in reducing the amount of soluble nutrients present in the
water, such as nitrate and ortho-phosphorus.
The basic elements of a wet pond are as follows: A stabilized inlet prevents erosion at the entrance to
the pond. It may be necessary to install energy dissipaters. The permanent pool is usually maintained
at a depth between 3 and 8 ft. The shape of the pool can help improve the performance of the pond.
Maximizing the distance between the inlet and outlet provides more time for mixing of the new runoff
with the pond water and settling of pollutants. Overflow from the pond is released through outlet
structures to discharge flows at various elevations and peak flow rates. Soil conditions are important for
the proper functioning of the wet pond. The pond is a permanent pool, and thus must be constructed
such that the water must not be allowed to infiltrate from the permanent portion of the pool. It is difficult
to form a pool in soils with high infiltration rates soon after construction.
ADVANTAGES
1. Wet ponds have recreational and aesthetic benefits due to the incorporation of permanent pools in
the design.
2. Wet ponds offer flood control benefits in addition to water quality benefits.
3. Wet ponds can be used to handle large drainage areas.
4. High pollutant removal efficiencies for sediment, total phosphorus, and total nitrogen are achievable
when the volume of the permanent pool is at least three times the water quality volume (the volume to
be treated).
5. A wet pond removes pollutants from water by both physical and biological processes, thus they are
more effective at removing pollutants than extended/dry detention basins.
6. Creation of aquatic and terrestrial habitat.
WET POND MAINTENANCE
Maintenance Refer to the checklist provided in Figure 702-7 for operation, maintenance and inspection
of stormwater ponds. The checklist is for the use of the BMP owner in performing routine inspections.
The City will perform annual inspections of BMPs, using a similar checklist. The developer/owner is
responsible for the cost of maintenance and annual inspections. 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. Removal debris from inlet and outlet structures
2. Removal of invasive vegetation from all side slopes as directed by Hamilton County Surveyor and the
City of Carmel Urban Forester
3. Removal of sediment accumulation from permanent pool area when 50% full
4. Removal of woody vegetation from the pond
STORM DRAIN INSERT
DESCRIPTION Storm drain inserts can be a variety of devices that are used in storm drain conveyance
systems to reduce pollutant loadings in stormwater runoff. Most storm drain inserts reduce oil and
grease, debris, and suspended solids through gravity, centrifugal force, or other methods. BMPs such
as these can be particularly useful in areas susceptible to spills of petroleum products, such as gas
stations.
See the following pages for storm drain insert specifications, installation, maintenance, and TSS.
Trapped sediments and floatable oils must be pumped out regularly to maintain the effectiveness of the
units.
ADVANTAGES
1. Prefabricated for different standard storm drain designs.
2. Require minimal space to install.

5.0 Identification of Drainage Structures to Determine FLEXSTORM Item Codes:
5.1 The Installer (Contactor) shallinspect the plans and/or worksite to determine the quantity of each
drainage structure casting type. The foundry casting number or the exact grate size and clear
opening size will provide the information necessary to identify the required FLEXSTORM inlet
Filter part number, Inlet Filters are supplied to the field pre -configured to fit the specified
drainage structure. [tern Codes can be built using the FLEXSTORM Product Configurator at
maivi.inleffifters-com. Detailed Submittal I Specification drawings are linked to each Item Code
and available for download by engineers and contractors to include on plans and/or verify field
inlet requirements. An example of a typical drawing is shown below-

Installation Into Standard Grated Drainage Structures:
6A Remove the grate from the c-asting or concrete drainage structure. Clean the Ledge (lip) of the
casting frame or drainage structure to ensure it is free of stone and dirt- Drop in the
'FLEXSTORM Inlet Filter through the clear opening and be sure the suspension hangers rest
firmly on the inside [edge (lip) of the casting. Replace the grate and confirm it is elevated no
more than '118', which is the thickness of the steel hangers- For Curb Box Intel Filters: Insert
FLEXSTORM CATCH IT inlet Filter as described above, pull the rear curb guard flap up and
over the open curb box until fight, align magnets to ensure firm attachment to the top portion of
the Curb box casting- If the curb back opening is not magnetic, slide a typical rock sack or 2 x 4
through the 2-ply rear curb box flap to create a dam which M11 direct runoff into the sediment
bag-

7.0 Maintenance Guidelines: The frequency of maintenance will vary depending on the application
(during construction, post construction, or industrial use), the area .of installation (relative to grade
and runoff exposure), and the time of year relative to the geographic location (infrequent rain,
year round rain, rain and snow conditions). The FILEXSTORM Operation& Maintenance Plan
(as shown in 7.5) or other maintenance log should be kept on file.
7.1 Frequency of Inspect:ions- Construction site inspection should occur following each Ya" or more
rain event. Post Construction inspections should occur three times per year (every four
months) in areas with year round rainfall and three times per year (every three months) in areas
with rainy seasons before and after snowfall season. Industrial application site inspections
(loading ramps, wash racks, maintenance facilities) should occur on a regularly scheduled basis
no less than three times per year.
7.2 General Maintenance for standard sediment bags: Upon inspection, the FLEXSTORM Inlet
Filter should be emptied if the sediment bag is more than half filled with sediment and debris, or
as directed by the Engineer- Remove the grate, engage the lifting bars or handles with the
FLEXSTORM Removal Tod], and lift the FILEXSTORM Inlet Filter from the drainage structure_
(Machineassistance is not required. Dispose of the sediment or debris as directed by the
Engineer. As an alternative, an industrial vacuum may be used to collect the accumulated
sediment if available- Remove any caked on silt from the sediment bag and reverse flush the
bag for optimal filtration- Replace the bag if the geotexffle is torn or punctured to '/,' diameter or
greater on the lower half of the bag. If properly maintained, the Woven sediment bag will last a
minimum of 4 years in the field.
7.3 Inspection and Handling of the FLEXSTORM PC I PC+ post construction sediment bag: The
PC+ sediment bags will collect oil until saturated, Both the Adsorb -it filter liner and the skimmer
pouch will retain oil- The volume of oils retained will depend on sediment bag size. Unlike
other passive oil sorbent products, Adsorb -it filter fabric has the ability to remove hydrocarbons
at high flow rates while retaining 10- 20 times its weight in oil (weight of fabric is 12-8 oz I sci
yd)- The average 2'x2'PC Bag contains approx.8 scl yds, or 10 oz of fabric. At56%
saturation, the average Adsorb -it lined PC filter will retain approximately 75 oz (4.2 Ibs) of oil -
Once the bag has become saturated with oils, it can be centrifuged or passed through a wringer
to recover the o4s, and the fabric reused with 85% to 90% efficacy- If A is determined, per
Maintenance Contracts or Engineering Instructions, that the saturated PC sediment bags will be
completely replaced, K is the responsibility of the service technician to place the filter medium
and associated debris, in an approved container and dispose of in accordance with EPA
regulations- Spent Adsorb -it can be recycled for its fuel value through waste to energy
incineration with a higher BTU per pound value than coal. The oil skimmers start white in color
and will gradually turn browniblack as they become saturated, indicating time for
replacement. The average skimmer pouch will a' sorb approximately 62 oz (4 lbs) of oil before
requiring replacement- To remove the Pouch simply unclip it from the swivel strap sewn to the
bottom of the bag. Dispose of all oil contaminated products in accordance to EPA guidelines -
The ClearTec Rubberizer media used in the pouch, since a solidifier, will not [each under
pressure and can be disposed of in most landflls, recycled for industrial applications, or bumped
as fuel
15
7.4 Sediment Bag Replacement When replacing a Sediment Bag, remove the . bag by loosening or
cuffing off the clamping ;band. Take the new sediment bag, which is equippedMh a stainless
steel worm drive clamping band, and use a drill or screew driver to tighten the bag around the
frame channel. Ensure the bag is secure and that there is no slack around the perimeter of the
Band. For Oil absorbent boom bags, simply replace the oil boom or pouch when saturated by
sliding, it through the mesh support sleeve-

GENERAL INSPECTION AND MAINTENANCE ACTIVITIES
BMP (best management practice) owners must routinely inspect BMPs to verify that all BMP
components are functioning as designed and are not in danger of failing. All BMPs need maintenance
to function as water quality and quantity enhancements. Maintenance can range from dredging
sediment out of the treatment area to mowing grass.
Inspections must be documented on the inspection form included in this Operation and Maintenance
Manual.
The BMP Owner agrees to follow maintenance and inspection program:
