(approval to be implemented with subsequent construction).
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
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.
port-o-lets are not to be placed in the street.
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.
Inspection Schedule/Reporting
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
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.
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
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.
The proposed land use will consist of single family residential houses. The pollutants and sources
of each pollutant normally expected from these types of land uses are listed below:
Pollutant Source: Passenger vehicles, delivery vehicles, and trucks
Type of Pollutant: Oil, gasoline, diesel fuel, any hydrocarbon associated with vehicular fuels and
lubricants, grease, antifreeze, windshield cleaner solution, brake fluid, brake dust, rubber, glass,
metal and plastic fragments, grit, road de-icing materials
