GENERAL INFORMATION
The purpose of water quality Best Management Practices is to filter the first flush of rainwater
before it enters the downstream lakes and streams. Through the use of these Best Management
Practices, the sediment and pollutant load in stormwater runoff is reduced, and in many cases the
quantity of stormwater water runoff generated is also reduced. The use of Best Management
Practices also helps to reduce hydrocarbons, trash and debris from entering waterways.
OWNER RESPONSIBILITY
The BMP Owner shall be responsible for all maintenance and costs associated with the proposed
BMPs. In addition, it is the owner's responsibility to perform and/or pay for inspections and
maintenance as recommended below.
RIGHT OF ENTRY
City of Carmel representatives have the right to enter the property to inspect and, if required,
maintain the BMPs at any time.
ANNUAL INSPECTION REPORTS
Annual inspection reports shall be submitted to the City of Carmel for each BMP. 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 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 of
Carmel.

SECTION II
SITE INFORMATION
The site contains 3 Best Management Practice (BMP) for the purpose of sediment removal. These
BMP's are an Aqua -Swirl XC-10, Hydro International Downstream Defender (4ft), as well as a
Wet Detention Pond. The Wet Detention Pond is located at the southern end of the project and the
Aqua -Swirl XC-10 and Hydro International Downstream Defender are located downstream of the
storm network system prior to the storm sewer outlet.
See the attached site exhibits for BMP and storm sewer locations.
The City of Carmel will require annual inspection reports of the water quality BMPs.
O AMERICAN STRUCTUREPOINT, INC.
SECTION III
STORM STRUCTURE MAINTENANCE
Storm structures are set at storm sewer pipe connections. Unless you have OSHA approved
training and equipment, never enter a manhole.
Inspection
All inlet castings should be inspected monthly and after each rainfall event. More frequent
inspections should be performed in areas where there is higher potential for trash or litter (e.g.
retail establishments) and during the fall when leaves are present on the ground. Check the frame
and lid for cracks and wear, such as rocking lids or lids moved by traffic.
Storm structures and the surrounding areas should be inspected annually for pollutants such as
leaks from dumpsters, minor spills, and oil dumping. Take action to have the pollutant source
removed.
Cleaning
Clean structures when there is a blockage of a water flow path or when sediment depth reaches 6".
Cleaning should be performed in a way that ensures removed sediment and water is not discharged
back into the storm sewer.
Safety
Work inside underground structures requires special OSHA -required confined space equipment
and procedures. The most practical option may be to contract with a sewer cleaning contractor.
Materials Handling
Disposal of waste from maintenance of drainage facilities shall be conducted in accordance with
federal, state, and local regulations. Removed sediment must be disposed in the garbage as solid
waste. Water should be disposed of in a sanitary sewer after oils are removed using oil absorbent
materials or other mechanical means. Used oil absorbents should be recycled or disposed
according to the manufacturer's instructions.
Repairs
Repair all security and access features so they are fully functional. This includes locking lids,
covers, and ladder rungs. Replace broken parts or lids that rock or are moved by traffic.
O AMERICAN STRUCTUREPOINT, INC.
SECTION IV
CONVEYANCE MAINTENANCE (STORM SEWER)
Storm sewer pipes convey stormwater. Pipes are built from many materials and are sometimes
perforated to allow stormwater to infiltrate into the ground. Storm pipes are cleaned to remove
sediment or blockages when problems are identified. Storm pipes must be clear of obstructions
and breaks to prevent localized flooding.
Inspection
Pipes are difficult to inspect requiring special equipment and training. Usually, if a problem occurs
the owner needs to call a sewer or plumbing contractor to inspect, repair or clean pipelines.
Cleaning
Clean pipes when sediment depth is greater than ''a of pipe diameter, with a maximum sediment
depth of 6". VI` hen cleaning a pipe, minimize sediment and debris discharges from pipes to the
storm sewer. Install downstream debris traps (where applicable) before cleaning and then remove
material. Generally, use mechanical methods to remove root obstructions from inside storm sewer
pipes. Do not put root -dissolving chemicals in storm sewer pipes. If there is a problem, remove
the vegetation over the line.
Safely
Work inside underground structures requires special OSHA -required confined space equipment
and procedures. The most practical option may be to contract with a sewer --cleaning contractor.
Materials Handling
Sediment and debris from pipes should be disposed in the garbage as solid waste. Pick out any
rocks first.
Repairs
Repair or replace pipes when a dent or break closes more than 20 percent of the pipe diameter.
Repair or replace pipes damaged by deterioration.
AMERICAN STRUCTUREPOINT, INC.
SECTION V
WET DETENTION SYSTEM
The site contains a wet -detention system on the southern end of the property.
Detention facilities are designed to hold and slowly release stormwater by use of a pond and a
specially designed control structure. Pond banks are to be planted with native vegetation per
landscape plan.
For details of wet detention facility shape and plantings, reference Section X of this manual.
Inspection
Inspect the facility for oil and other pollutants and remove any pollutants greater in volume than a
surface sheen. Inspect sediment sump if present. Identify and report pollutant sources to the
facility. Inspect vegetation and perform maintenance activities if necessary. Review construction
plans for any original planting plan.
Cleaning
Remove trash and sediment as necessary.
Materials Handling
Disposal of waste from maintenance of drainage facilities shall be conducted in accordance with
federal, state, and local regulations. Removed sediment must be disposed in the garbage as solid
waste.
Repairs
Repair and seed bare areas. Repair eroded slopes when rills form, where the cause of damage is
present, or there is the potential for future erosion. If berms or dams show signs of settlement or
sinkholes, serious problems may be occurring. Spillway areas should be completely covered by
established vegetation.
O AMERICAN STRUCTUREhOINT, INC.
SECTION A
WATER QUALITY UNITS
The site contains one Hydra International Downstream Defender (4ft) unit, and one AquaSwirl
XC-10 located at the downstream end (wet pond) of the proposed stone sewers.
Swirl concentrators are designed to remove sediment, debris, and free oil from entering the sewer
system. After construction the swirl concentrator should be inspected every six months and
cleaned as needed or once a year regardless of whether it has reached full pollutant storage
capacity. Disposal of all sediment, in addition to local requirements, must be in accordance with
all federal and state requirements. See the attached O&M Manual for the swirl concentrator for
complete details of inspection and cleaning.
Inspection
Inspect the unit every six months. The inspection should determine sediment depth, accumulation
of trash and litter, and the specific maintenance and repairs needed. Annually check for cracks
large enough to let soil enter the vault, broken or defective plates and baffles, and crushed or
damaged pipes.
Cleaning
Remove trash and litter from the vault, inlet and piping when present. Remove sediment when it
accumulates to the manufacturer's maximum recommended depth. Cleaning should be performed
in a way that ensures removed sediment and water is not discharged back into the storm sewer.
Safety
Work inside underground structures requires special OSHA -required confined space equipment
and procedures
Materials Handling
Disposal of waste from maintenance of drainage facilities shall be conducted in accordance with
federal, state, and local regulations. Removed sediment must be disposed in the garbage as solid
waste. Water should be disposed of in a sanitary sewer after oils are removed using oil absorbent
materials or other mechanical means. Used oil absorbents should be recycled or disposed
according to the manufacturer's instructions.
Repairs
Repair any cracked or defective plates or baffles. Repair all security and access features so they
are fully functional. This includes locking lids, covers, and ladder rungs. Replace broken parts or
lids that rock or are moved by traffic

NATIVE PLANTINGS MAINTENANCE
LONG TERM MAINTENANCE OF NATIVE PLANTINGS
Seeded lake edge community, plugs at ►rater line.
YEAR ONE:
• Maintain and water fowl fencing that is in place until plugs, if present, have rooted in.
Remove after the second growing season.
• Ensure lawn is established prior to installing native seed and plugs. This will minimize runoff
of fertilizers and erosion.
• Maintain erosion control blanked on any seeded areas until established.
• Remove monthly invasive species, especially Canadian Thistle, Queen Anne's Lace, and
Sweet Clover
• If weed growth exceeds 10", mow to a height of 4". Do not cut any vegetation established at
or below the water line.
• Ensure seeded areas and plugs receive 1" of water per week for the first 8
weeks. YEAR TWO:
• At the beginning of the growing season (late spring), mow if weed growth exceeds 20
percent of the plantings. Mow to a height of 4".
• Remove invasive species, especially Canadian Thistle, Queen Anne's Lace, and Sweet
Clover FUTURE YEARS
• Monitor for weed growth. If present, remove and seed.
• Mow in early spring to keep woody plant species at bay. Remove clippings to avoid
excess mulch.
DO NOT USE THE FOLLOWING ITEMS IN NATIVE PLANTINGS UNLESS DIRECTED BY A NATIVE
PLANTS EXPERT.

Maintenance Items
Inspection
Floatable Debris and Oil
1. Remove manhole lid to expose liquid surface of Aqua-SwTH.
2 Remove floatable debris with basket or net if any is present.
3. If a hydrocarbon spill has occurred, (e.g. more than a sheen of oil or gas is present) the system should be cleaned immediately
(see "Cleaning" Figure 3).
Note: Water in an Aqua-Swirflo can appear black like oil due to the dark body of the surrounding structure. Oil appears
darker than water in the system and Is usually accompanied by debris (e.g. Styrofoam, etc.) with obvious signs of oil stains.
The depth of oil can be measured with an oillwater interface probe, a stadia rod with water phylic paste,
a coliwasa, or by simply collecting a representative sample with a jar attached to a rod.
4. If hydrocarbon abs crbant floc or pads are used, these should be inspected to determine whether they are loaded with
hydrocarbons. Th s will be indicated by a dark cola ration of the pad or floc. Pads and/or floc should be removed and
disposed of in accordance with City of Indianapolis and any applicable state and/or federal laws if they contain hydrocarbons,
Sediment Accumulation
Lower a dipstick tube equipped with a ball valve (e_g. Sludge Judge or similar device) into Aqua-SAthrough the service access provided.
Measure the depth of the sludge. The sludge should not exceed 6" depth before maintenance. See Figures 1 and 2,
s
Figure 1
i
Figure 2
Aqua-Swirim O and M Manual
Page 1
Inspection (continued)
Diversion Structures
If an external diversion structure is present on the site, this should be inspected for the following items.
1. Inspect weir or other structure for structural decay or damage. Weirs are more susceptible to damage than off -set piping and should
be checked to confirm that they are not crumbling or decaying,
2. Inspect diversion structure and by-pass piping for signs of structural damage or blockage from debris or sediment accumulation_
3. Measure elevations on diversion weir or piping to ensure it is consistent with site plan design.
4. Inspect downstream structure in diversion system for signs of blockage or structural failure.
Cleaning
Remove sediments, oils and other
floatable pollutants with a vactor_ Dispose of all waste in
accordance with City of Ind anapotis and any applicable state,
and/or federal requirements.
Oil should be pumped and removed with any liquids and
sediments that have been trapped :n the system.
These liquids should be taken to an industrial waste water
treatment facility for treatment: LLquids and solids pumped fron
the AquaSwirfm should not be dumped back into the
stormwater system or into a sanitary sewer.
Figure 3
Note: The AquaSwirirm is designed so that entry to the system is not necessary for inspection or maintenance. If, however,
you wish to enter the system, this is an OSHA confined space entry and OSHA confined space entry procedures should be followed
to enter the system.
Maintenance Schedule
During Construction
Inspect the AquaSwirlm every three months (minimum) and clean the system as needed. The AquaSy7M should be inspected and
cleaned at the end of construction regardless of whether it has reached its sediment or oil storage capacity.
First Year Post -Construction
Inspect the AquaSwirfm every six months and clean the system as needed.
Second and Subsequent Years Post-Constructiol
If the AquaSwi6 " did not reach full sediment or floatable pollutant capacity in the First Year Post-Construcho
the system can be inspected once annually and cleaned as needed or bi-annually at a minims
If the AquaSwirfm reached full sediment or floatable pollutant capacity in less than 12 months in the First Year Post -Construction.
the system should be inspected at least once every six months and cleaned as needed. If site monitoring indicates that trapped sediment
hardens over time, the AquabwiA" should be cleaned prior to sediment hardening regardless of whether it has reached its sediment storage capacity.
Bypass Structures
Bypass structures should be inspected whenever the AquaSwiW is inspected and maintained as needed.

* The AquaSwirf" should be cleaned at the end of the first year post construction if it is at or near its pollutant storage capcac ty.
Otherwise, the system can be cleaned at a later date depending on how quickly the sediment starts to harden.

*If the AquaSwirfm did not reach full sediment or floatable pollutant capacity in the First Year Post -Construction, the system can be inspected
once annually. If the AquaSwiam reached full sediment or floalable pollutant capacity in less than 12 months in the First Year
Post -Construction, the system should be inspected as frequently as past history warrants and cleaned as needed.
Regardless of whether the Aqua$wiAm reaches full sed ment or floatable storage capacity. it should be cleaned
frequently enough to prevent captured sediments from hardening. Normally, cleaning once every two to three years should be sufficient to
prevent sediments from hardening.
'The bypass system should be inspected with each AquaSwilf inspection and maintained as needed.
