Section B
1. Potential Pollutants during construction includes but are not limited to: fossil fuels, oil, grease,
paint, human waste, silt
2. The erosion control measures and schedule is shown on the erosion control plan.
(See Sheet _4_ of _11)
3. The Stone entrance is shown on the erosion control plan (See Sheet _4_ of _11)
4. The sediment control measures for sheet flow are shown on the erosion control plan.
(See Sheet _4_ of _11)
5. The sediment control measures for concentrated flow are not shown on the erosion control
plan because there is no concentrated flow outside of the paved areas.
6. The inlet protection measures are shown on the erosion control plan.
(See Sheet _4_ of _11)
7. There are no runoff control measures because the site drains onto the pavement.
8. There are no storm water outlets on this project. The sewers connect to the existing system.
9. The are no grade stabilization measures. The subgrade of the pavement will be stabilized by
stone base and the building will be compacted and a stone base added prior to footing
installation.
10. Each measure is shown on the plans along with the appropriate details and specifications.
11. The temporary seeding measures for each season are shown on the erosion control plan.
(See Sheet _4_ of _11) See note 6 of Erosion Control Measures and Schedule for surface
stabilization.
12, The Permanent seeding measures for each season are shown on the erosion control plan.
(See Sheet _4_ of _11)
13. All fueling, lubricating, maintenance on construction equipment, dumpsters, port-o- lets to be
confined to the Staging Area adjacent to the construction entrance. In the event that a spill
occurs, the proper steps for containment must be taken emediately. A spill kit must be on site
at all times and readily available for access to contain any type of spill. IDEM has certain
requirements for larger spills that must be addressed. The contractor must have an IDEM spill
check list on site at all times. Telephone the local Fire Department for procedures and
notification (317) 571-2600. All local Emergency numbers must be posted on site. Concrete
washout area must be in the Staging area. The hardened concrete washout must be removed
and disposed of in the on site trash dumpsters for construction activities. All construction
trash and/or debris is to be disposed of in the construction trash dumpster located in the
staging area. The trash and/or debris must be picked up prior to completion of each days
construction activities. The county surveyor needs to be contacted in the event of a spill on
site. The county surveyor's telephone number is (317) 776-8495. The Staging area is shown
on the erosion control plan. (See Sheet _4_ of _11)
14. Person in charge of and knowledgeable about erosion and sediment control shall inspect the
site for stormwater pollution prevention deficiencies at least weekly and again within 24 hours
of every 1/2 inch rain event. Construction Entrance shall be repaired if it is not performing
properly. Silt fence shall be repaired/replaced in the event that it has failed. Drop Inlet
Protection Basket shall be repaired/ replaced if failed sediment removed. Curb Inlet
Protection shall be repaired/replaced if failed sediment removed. Sediment Traps shall
be cleaned out if they are over 50% full of sediment.
15. There is only one lot in this project.

Section C
Proposed site will be a commercial development. Potential pollutants from this
type of development include, but are not limited to: fluids and debris from parked
vehicles vehicular traffic which could include: fossil fuels, oil, grease,
antifreeze, brake fluid, window washer fluid, rubber, plastic, metal fragments,
grit (sediment) from wearing of the road surface, trash (including bacteria
and other biological agents contained in the trash) from littering and other
types of improper disposal or storage, and elevated receiving water
temperatures from stormwater runoff contact with impervious surfaces.
2. The existing stormwater quality measures will remain in place until no erosion
or siltation can take place. The proposed Aqua-Swirl stormwater quality measure
for the site will remain in place as long as the site is a commercial property.
3. The proposed site will contain a storm sewer network that eventually outlets
into the existing pond. The majority of the site will be draining into
a storm sewer network and swales, which will act as filters throughout the
life of the commercial lot. The storm sewer system drains into an Aqua-Swirl
storm quality structure (manhole 28) that collects the fossil fuels, oil, grease,
antifreeze, break fluid, window washer fluid, rubber, plastic, metal fragments, and
trash with it's baffle. The Aqua-Swirl is checked on a regular basis and cleaned
by a vacuum truck every six months (soon if needed by visual inspection after
storm events).
4. Catch basins are provided on the drainage plan. Details are provided on the
Detail sheets.
5. The owner is responsible for post construction maintenance until the
property is sold, and then transferring responsibility for post construction
maintenance to the new owner of the site. The site is considered a basin to the
regulated drain. If this project is ever considered a regulated drain site, then the
maintenance will be the county's responsibility. A maintenance manual has been
developed by the manufacturer and has be given to the County Surveyor's office.
A copy of the manual has also been given to the Soil and Water Conservation
District for this site. Any barren lawn areas shall be seeded and/or stabilized.
Aqua-Swirl structure shall be inspected annually. Clear all drains to make sure
they are functioning properly. Clean any debris from storm inlets and trash rack.
Replace if rust is excessive. Remove floatable debris. Check for visible pollution
and their sources. Contact the local fire department for guidance. Take note of
complaints by ad joiners and any potential public hazards. Contact the local Soil
and Water Conservation District office for guidance.

Proo Inlet Protection Basket
It is the intent of this device to detain water for the purpose of
allowing suspended solids in the water to settle but before the water
enters the storm structure. Some filtering will occur as water passes
through the device.
The bottom of this device is to seal against the flat outer part of
the casting. The overall dimension of the basket shall be no smaller
than the water inlet perforations in the casting and no larger than
the outer dimensions of the casting. The height shall he 15 The
basket frame shall be welded wire mesh rolled or bent and welded to
itself to fit the casting. The wire size shall be no smaller than .149"
dia. and openings no larger than 18 sq in. It is important that the
bottom of the wire frame be smooth so as not to allow any leakage
between the basket and casting. The top of the basket shall be open
to prevent flooding during heavy storm events. Fabric shall be woven
polypropylene allowing 15-2.5 gal/min/sq in. If non-woven fabric is
used, the maintenance intervals should be increased to replace silt
laden fabric. The fabric shall be attoched to the frame and folded
under the bottom to help seal against the casting. This device should
be used in conjunction with other Best Management Practices to
maximize the efficiency of tire erosion control plan. Suppliers for this
product include: Lakeside Supply Inc. (31 7) 281-2661, Turfgrass Inc.
(317) 894-3276.
