PROJECT NUMBER AND COUNTY

APPENDIX R

See TOPPS 7120-3.

(National Pollutant Discharge Elimination System (NPDES) Phase 1)

• 
  Projects that will disturb less than 5 acres, the Erosion, Sedimentation, and Pollution Control Plan will consist of the Best Management Practices (BMP) Location Details for the final project conditions that are sufficient for quantity computations. Erosion control pay items, not Lump Sum, must be included. BMP Location Details for each stage of construction will be required when stage construction is necessary.
  

Placement of BMP Location Details remains unchanged and will not require any additional sheets except for staged BMP Location Details.

• 
  Projects that will disturb five (5) or more acres are required to have detailed Erosion, Sedimentation, and Pollution Control Plans (ESPCP) and a Comprehensive Monitoring Plan (CMP). An Erosion, Sedimentation, and Pollution Control Plan will be required for each stage of construction. The ESPCP and CMP will be a complete, stand-alone section within the construction plans. The ESPCP will consist of:
  

1. 
   Cover Sheet
   

1. 
   Shall be signed and sealed by the Consultant (if applicable) and the Chief Engineer, and
   
2. 
   Shall contain the required certification statements.
   

2. 
   Erosion, Sedimentation, and Pollution Control General Notes Sheet,
   

b. Statement about storm water management and pollution control, and

c. Statement about stabilization measures

3. 
   Erosion Control Watershed Map showing:
   

b. The before and after runoff coefficient factor for each watershed or peak flow before and after,

c. Drainage patterns - flow arrows,

1. 
   Cross drain sizes,
   
2. 
   Wetlands delineated with areas (acres),
   
3. 
   Receiving waters,
   
4. 
   Down stream lakes and ponds, and
   

4. 
   Best Management Practices (BMP) location details,
   

5. 
   Comprehensive Monitoring Program General Notes Sheet,
   

b. One representative outfall may be monitored for linear projects. Linear projects are defined, as being at least 25 times longer than it is wide. All outfalls must be monitored on non-linear projects.

c. Site monitoring locations (use of USGS Topographical sheets larger than 1”=2000’ is recommended),

1. 
   Outfalls to be monitored - outfalls to streams,
   
2. 
   Streams (as dictated by OEL),
   
3. 
   Receiving waters - hand draw if necessary to first blue line stream noting any lakes or ponds in the path, and
   
4. 
   All other Outfalls must be highlighted to the first blue line stream noting any lakes or ponds in the outfall path.
   

6. 
   Construction Details (for erosion control items only), and
   
7. 
   GA Standards (for erosion control items only).
   

The stand-alone ESPCP and CMP will be placed in back of a set of final construction plans. This will be after the cross sections or bridge plans if included.

• 
  Projects that will disturb fifty (50) or more acres require the same treatment as projects disturbing five or more acres, as outlined above. In addition, the ESPCP & CMP must be submitted by the Office of Contract Administration to the Environmental Protection Division (EPD) along with the Notice of Intent (NOI).
  

A written explanation will be required when a sediment basin is not set up for each outfall from the project (See 2a.).

Coordinate the Erosion, Sedimentation, and Pollution Control Plan and the Comprehensive Monitoring Program with the approved environmental document and any environmental permits. Example, do not locate a sediment basin in a wetland but if you must, make sure it was addressed in the environmental document and environmental permits (e.g., USCEC 404).
Use the appropriate number and type of erosion control devices as established in the Department’s BMP’s. If you err, err on the side of environmental protection and use as many devices as feasible and practical to ensure adequate control of sediment and erosion.

Attachments

• 
  Vehicular volumes for each traffic movement from each approach, classified by type of vehicle (heavy trucks, passenger cars and light trucks, public-transit vehicles, and, in some locations, bicycles), during each 15-min period of the 2 hours in the morning, 2 hours at midday, and 2 hours in the afternoon during which total traffic entering the intersection is greatest,
  

• 
  Pedestrian volume counts on each crosswalk during the same periods as the vehicular counts just described, and also during hours of highest pedestrian volume (where young or elderly persons need special consideration, the pedestrians may be age-classified by general observation),
  

• 
  Existing conditions diagram,
  

• 
  Location map,
  

• 
  The posted or statutory speed limit or the 85^th-percentile speed on the uncontrolled approaches to the location,
  

• 
  An existing condition diagram based on field observations showing details of the physical layout, including such features as adjacent intersections, highway geometrics, traffic control, grades, channelization, sight-distance restrictions, bus stops and routings, parking conditions, pavement markings, street lighting, driveways (curb cuts), nearby railroad crossings, distance to nearest signals, utility poles and fixtures, delays, and adjacent land use,
  

• 
  A collision diagram showing accident experience by type, location, direction of movement, severity, time of day, and day of week for at least one year,
  

• 
  Traffic signal warrant analysis,
  

• 
  Capacity Analysis and evaluation of turn lane necessity,
  

• 
  Proposed Improvements diagram,
  

• 
  Conceptual signal design (if warranted), and
  

• 
  Recommendations and Conclusions
  

Additional data may be useful in evaluating the potential improvements in the overall operation and safety of the intersection. These include vehicle-seconds of delay by approach, the number and distribution of gaps on the major street, and pedestrian delay time. Analysis of these data may show that, although warranted by vehicular volumes alone, a traffic signal may not be justified.
