• A description of the nature of the construction activity (e.g., low density residential, shopping mall, highway, etc.) Estimates of the total area of the site and the total area of the site that is expected to be disturbed;

Provide one or two sentence description.

• A description of the intended sequence of major activities that disturb soils for major portions of the site, with approximate dates.

Include a more detailed description of each activity (e.g., stormwater runoff controls, grubbing, stockpiling, excavation, grading, sodding, sewer lines, swales, utilities, etc.)

• A legible site map, showing the entire site, indicating the following:

drainage patterns and approximate slopes anticipated after major grading activities; areas of soil disturbance; areas that will not be disturbed;

locations of off-site material, waste, borrow, or equipment storage areas;

location of all surface waters (including wetlands); locations where storm water discharges to a surface water, any areas to be protected, discharge locations..

• Marked up construction drawings with enough detail to implement BMP’s. Add statement on plans that “Additional BMPs will be added if existing BMPs prove ineffective.” Or when specific locations are not practical. State “silt fence or other suitable barriers shall be place down slope of all bare soil areas, and maintained until stabilized”

• A general location map

Must have enough detail to identify the location of your construction site and the receiving waters within one mile of the site.

e.g. “Discharge from the site is to various stormwater conveyances to Sitting bear Creek which is a tributary of East Cache Creek. There are no wetlands in the vicinity of this project, or they are depicted on the site map or location map.” Only East Cache Creek upstream of the Wastewater treatment plant is listed as impaired.

No adverse effect on endangered or threatened species or habitats were identified.”

“Impact on Historical Places. The site has been evaluated by the Fort Sill Cultural Resources Manager through the NEPA process for federal projects.

Workers shall stop work immediately and notify the Fort Sill Environmental Quality office upon discovery of items with potential historical significance including but not limited to:

arrowheads, bones, old bottles or building materials, building foundations, and suspected gravesites.

• Stormwater Control Measures e.g.

*Straw or hay bales are no longer allowed as BMPs* Silt fences to be placed down slope of exposed areas Straw wattles downslope of stock piles Gravel bags around curb inlets Erosion control blankets on steep slopes Street sweeping daily to remove sediment on roadways Policing of litter on site All controls will be installed and maintained in accordance with the manufacturer’s specifications and good engineering practices.

• Stabilization Practices Gravel or sod to match surrounding use for permanent stabilization.

Hay mulch or erosion blankets for temporary stabilization.

• Structural Practices Rip-rap at drainage outlets, diversion berms, construction entrances, check dams etc that are being used. Sediment basins for sites over 10 acres.

• Spill Prevention Response

We will maintain suitable spill response equipment on site for potential accidental release of fuel, oil, or chemicals, and store materials away from storm drains and waterways.

"For large spills or a spill emergency the Fort Sill fire department will be notified via 911 system. Post emergency response, the fire department notifies the Fort Sill Environmental Quality Division who makes a determination if further State or Federal notifications are required.

The contractor notifies the contracting officer or contracting officer’s representative who can then coordinate with Fort Sill Environmental Quality Division on any further required cleanup actions. Fort Sill Environmental Quality Division will make any required notifications to regulatory agencies."

• Waste Management Dumpsters, trash containers, hauled to Fort Sill landfill. Port-a-johns

• Inspections to be performed and documented weekly and post half inch rainfall events. a copy of all inspection reports will be at the site or at an easily accessible location.

Include a copy of the inspection form. (sample insp. Form below)

• Corrective actions are performed and documented for each identified deficiency or maintenance requirement on the inspection report. Corrective actions are completed within 7 calendar days.

Include a copy of the corrective action form. (Sample insp. Form below) if the corrective action changes the swppp it must be updated within 7 calendar days.

• Staff Training Requirements: Personnel will be trained to understand the scope of their stormwater related job duties including the location of all stormwater controls on the site required by this permit, and how they are installed and maintained.

• Log of major earth disturbing activities.

(can reference other contract required daily reports if they can be readily produced)

• Non-Storm Water Discharges that are combined with storm water discharges associated with construction activity must be identified in the SWP3.
