Erosion and Sediment Control Inspections
All controls should be inspected at least once every seven (7) calendar days and following any storm event of 0.5 inch or
greater. The following is a list of inspection/maintenance practices that will be used for specific controls:
1.Geotextiles/Erosion Control Mats: Missing or loose matting must be replaced or re-anchored.
2.Curb Inlet Protection shall be cleaned at least once per week and after every 0.5 inch rainfall event.
3.Mulching: Inspected for thin or bare spots caused by natural decomposition or weather-related events. Mulch in high
traffic area should be replaced on a regular basis to maintain uniform protection.
4.Silt Fence: Removal of built-up sediment will occur when the sediment reaches one-third the height of the fence.
5.Stabilized Construction Entrance: Periodic regrading and top dressing with additional stones.
6.Vegetation: Protect newly seeded areas from excessive runoff and traffic until vegetation is established. Establish a
watering and fertilizing schedule.
7.Good Housekeeping: Litter, construction debris, and construction chemicals exposed to stormwater shall be
prevented from becoming a pollutant source for stormwater discharges through screening of outfalls and daily pickup
of litter.
In the event that sediment escapes the construction site, off-site accumulations of sediment must be removed at a frequency
sufficient to minimize adverse impacts. An example of this may be the situation where sediment has washed into the street and
could be carried into the storm sewers by the next rainfall and/or pose a safety hazard to users of public streets.
Material Handling and Spill Prevention
Discharge of hazardous substances or oil into stormwater is subject to reporting requirements. In the event of a spill of a
hazardous substance, the operator is required to notify the National Response Center (1-800-424-8802) to properly report
the spill. In addition, the operator shall submit a written description of the release (including the type and amount of
material released, the date of the release, the circumstances of the release, and the steps to be taken to prevent future spills)
to the local MS-4.
Compliance of the site with the General Construction Permit remains the responsibility of all operators that have submitted
an NOI until such time as they have submitted a Notice of Termination (NOT). The permittee's authorization to discharge
under the General Construction Permit terminates at midnight of the day the NOT is signed.
All permittees must submit an NOT within thirty (30) days after one or more of the following conditions have been met:
1.Final stabilization has been achieved on all portions of the site for which the permittee was responsible.
2.Another operator/permittee has assumed control over all areas of the site that have not been finally stabilized.
3.In residential construction operations, temporary stabilization has been completed and the residence has been
transferred to the homeowner.
9.) GENERAL CONSTRUCTION SEQUENCE
1.The contractor shall schedule a Pre-construction meeting with the City of Carmel prior to any constructing on the site
being started. The contractor and/or developer shall notify IDEM and the City of Carmel 48 hours prior to start of
construction.
2.Following the required pre-construction meeting the contractor shall construct the “posting information center” on the
South side of the proposed construction entrance. The location of the posting information center is shown on Sheets
C300-C301. The posting information center is the location where a copy of the approved IDEM Rule 5 Permit,
Approved SWPP Plan, signed O&M Manual and Maintenance Logs are to be located. The contractor shall proceed to
construct the construction entrance after all posting requirements have been met.
3.Immediately following the installation of the construction entrance, the contractor shall construct the maintenance and
refueling area. Please refer to the maintenance and refueling area detail on Sheet C304.
4.After the maintenance and refueling area is constructed, the contractor shall construct the concrete washout area per
the specifications on Sheet C304. Concrete washout shall not be required if concrete truck is equipped with
self-contained chute system, similar to system provided by Enviroguard, or approved equal.
5.Prior to any earth moving the contractor shall install all silt fence as shown on Sheet C300 - C301. The details and
specifications for silt fence installation are located on Sheet C304.
6.The contractor shall protect all existing inlets with drop inlet protection baskets and fiber mats as shown on Sheet
C300 and C301. The details and specifications for the drop inlet baskets and fiber mats on Sheet C304.
7.When the “existing” site/construction limits are completely stabilized, the contractor shall start stripping the existing
top soil within the construction limits.
8.The contractor shall proceed to grade the site. The material to grade the site shall be excavated per the proposed cut
& fills as shown on Sheet C200.
9.The proposed storm sewer and sanitary sewer shall be installed concurrently with each other when crossings are
encountered.
10.Contractor shall install water main. The trench area shall be seeded and mulched immediately following the
installation of the water main.
11.The contractor shall prepare the sub-grade for the proposed road system. If lime stabilization is the method chosen,
dust shall be kept to a minimum. Dust shall be removed from the construction vehicles prior to leaving the site.
12.Contractor shall install all concrete roll curb.
13.Contractor shall install all asphalt pavement.
14.Contractor shall have all other appropriate utilities installed. It is ultimately the responsibility of the contractor to
ensure that the trench area is seeded and mulched immediately following the installation of each utility.
15.The contractor shall permanent seed all areas between the back of curb and the constructed pads and all other areas
that are illustrated on Sheet C302. The seed mixture and rate can be found on Sheets C304.
16.The contractor shall schedule a site inspection with the City of Carmel to ensure that the site is stabilized. After the
inspector approves the site conditions the contractor shall remove all temporary erosion control practices.
17.The post-construction erosion control practices then become the responsibility of the developer of this project.
18.The developer of this project shall continue to monitor this site for good house keeping on the post-construction
BMP's until a NOT is filed with IDEM.
10.) LOCATION OF PROPOSED SOIL STOCKPILES, BORROW, AND/OR DISPOSAL AREAS
None.
11.) TEMPORARY AND PERMANENT SURFACE STABILIZATION METHODS APPROPRIATE FOR EACH SEASON
Refer to Sheet C304, within the Seasonal Soil Protection Chart.
12.) EROSION AND SEDIMENT CONTROL SPECIFICATIONS FOR INDIVIDUAL BUILDING LOTS
Refer to individual building lot detail on sheet C304.
13.) MATERIAL HANDLING AND SPILL PREVENTION PLAN
Solid Waste Disposal
No solid material, including building materials, is permitted to be discharged to surface waters or buried on site. All solid
waste materials, including disposable materials incidental to the construction activity, must be collected in containers or
closed dumpsters. The collection containers must be emptied periodically and the collected material hauled to a landfill
permitted by the State and/or appropriate local municipality to accept the waste for disposal. Dumpsters and port-o-lets are
not to be placed in the street.
A foreman or supervisor should be designated in writing to oversee, enforce, and instruct construction workers on proper
solid waste procedures.
Hazardous Waste
Whenever possible, minimize the use of hazardous materials and generation of hazardous wastes. All hazardous waste
materials will be disposed in the manner specified by federal, state, or local regulations or by the manufacturer.
Use containment berms in fueling and maintenance areas and where potential for spills is high.
A foreman or supervisor should be designated in writing to oversee, enforce and instruct construction workers on proper
hazardous waste procedures. The location of any hazardous waste storage areas should be indicated on the stormwater
pollution prevention plan by the operator following on-site location of the facility.
Dust Control/Off-site Vehicle Tracking
During construction, water trucks should be used, as needed, by each contractor or subcontractor to reduce dust. After
construction, the site should be stabilized to reduce dust.
Construction traffic should enter and exit the site at a Construction Entrance with a rock pad or equivalent device. The
purpose of the rock pad is to minimize the amount of soil and mud that is tracked into existing streets. If sediment escapes
the construction site, off-site accumulations of sediment must be removed at a frequency sufficient to minimize offsite
impacts.
Construction Entrance
Locations where vehicles exit the site shall be inspected for evidence of off-site sediment tracking. Each contractor and subcontractor shall
be responsible for maintaining the Construction Entrance and other controls.
Material Storage Inspections
Inspectors must evaluate areas used for storage of materials that are exposed to precipitation. The purpose is to ensure that materials are
protected and/or impounded so that pollutants cannot discharge from storage areas. Off-site material storage areas used solely by the subject
project are considered to be part of the project and must be included in the erosion control plans and the site inspection reports. Soil
Stabilization Inspections
Seeded areas will be inspected to confirm that a healthy stand of vegetation is maintained. The site has achieved final stabilization once all
proposed roads are covered with pavement. And the remainder of the site has a stand of vegetation with at least 70% of the background
vegetation density. The density of 70% or greater must be maintained to be considered as stabilized. The operator or their representative will
water, fertilize, and reseed disturbed areas as needed to achieve this goal.
All impacted areas, as well as all erosion and sediment control devices, will be inspected every seven (7) calendar days and within 24 hours
after a rainfall of 0.5 inch or greater until an NOT is issued. Inspection reports after rain events are to be submitted to the City of Carmel
Engineering Department One, Civic Square, attention Storm Water Administrator.
Inspections shall be conducted and a written report prepared, by a designated and qualified person familiar with the USEPA NPDES Storm
Water General Permit, and the Project.
Inspection reports shall be completed including scope of the inspection, name(s) and qualifications of personnel making the inspection, the
date of the inspection, observations relating to the implementation of the SWPPP, and any actions taken as a result of incidents of
noncompliance noted during the inspection. The inspection report should state whether the site was in compliance or identify any incidents
of noncompliance. The contractor shall keep a copy of the inspection reports on site and permanently for a period of two years following
construction. The on-site reports may be requested by inspections conducted by the local MS-4.
