Erosion and sediment control policies and practices march 2006

Erosion and Sediment Control

Policies and Practices

March, 2006


Federal laws and regulations

Federal Laws and Regulations

  • Clean Water Act (CWA). Designed to protect our nations water resources. Identified point source and non-point source pollution prevention regulations.

    • 1987 amendments to CWA , Phase I, to address polluted discharges from storm sewers (non-point). Erosion and sediment control

    • March 2003, Phase II implemented, included all areas identified as an Urban Area by the Census Bureau base on the latest census.

  • The EPA is the lead regulatory agency.

    • EPA is the permitting agency on Native American Reservations.

    • The NPDES program is administered statewide by the North Dakota Department of Health (NDDOH).


What is the goal of erosion and sediment control

What is the goal of erosion and sediment control?

  • Stop erosion from occurring (mats, blankets, maintain vegetative cover)

  • When erosion occurs, incorporate sediment control measures to prevent transport of material. (silt fence, straw wattles, ditch checks)

  • Prevent sediment from leaving the project limits. Contain within NDDOT right-of-way.

  • Protect all water bodies (wetlands, streams, lakes, etc).


What has been done to address storm water issues within the nddot

What has been done to address storm water issues within the NDDOT?

  • Revised Standard Specifications and Drawings, additional environmental guidance available in the Design Manual.

  • Revised permit process

    • Memorandum of Agreement with NDDOH

    • Decision Document (NDDOT)

  • Developed an Erosion and Sediment Control Handbook.

  • Provide educational opportunities for NDDOT staff, consultants, and contractors.

  • Review new materials being used nationwide.


Nddot standard specifications

NDDOT Standard Specifications

  • Section 110 – Environmental Protection

  • Section 708 – Erosion Control

  • Section 709 – Geotextile Fabrics

  • Section 856 – Soil Retention Blankets


Nddot standard specifications1

NDDOT Standard Specifications

  • 110.03 – Preconstruction Conference.

    • “The contractor shall submit in writing, for acceptance at the preconstruction conference or before starting work on the construction, a temporary erosion and pollution control plan.”

  • 110.04 – Operational Controls

    • “Where a work area is adjacent to a live stream or lake, or runoff water from the work area enters a live stream or lake, the Contractor shell erect barriers or provide sediment basins to prevent direct runoff from reaching the live stream or lake.”

  • 110.05 – Erosion Controls

    • …”The Contractor shall incorporate all permanent erosion control features into the Project at the earliest practical time as outlined in the accepted Plan.”

  • 110.06 – Method of Measurement and Payment.

    • “Should the Contractor fail to control erosion, pollution, and siltation, the Engineer will employ outside assistance or state force to do the work. The direct costs, overhead costs, and engineering costs incurred under these condition will be deducted from payments due the Contractor for work done on the Contract.


2005 construction site review

2005 Construction Site Review

  • Prior to earth moving activities erosion and sediment control measures must be in place.

    • This means at locations where stormwater may leave NDDOT right-of-way (streams, lakes, wetlands, Waters of the State as defined by the permit. This does not include ESCM’s that are not to be implemented until after the initial earth work is performed (silt fence, straw wattles, etc.).

  • Contractor is responsible for inspecting and maintaining ESCM’s during construction phase of project

  • If you are the prime contractor and have subcontracted out the stormwater portion of the project, you are still responsible for inspecting and maintaining ESCM’s, if the sub cannot perform the duties (time frame) as defined by the permit. “Not my job” will not be an acceptable excuse.

  • Topsoil is to be stockpiled, not used as a haul road.

  • 24 hours to inspect ESCM’s after a .5 inch rain event or within 24 hours. This is a permit requirement!


2005 construction site review cont

2005 Construction Site Review cont.

  • Debris left behind after active construction must be removed immediately.

    • Appendix 2 of the ND Construction Permit –House Keeping and Operational Procedures

      • Concrete curing compound left along site for multiple days.

  • Those areas with a continuous positive slope within 200 lineal feet of a surface water, temporary erosion protection or permanent cover must be applied within 21 days of completing or ceasing earth moving activities.

  • Wetted perimeters must be stabilized within 200 lineal feet from the property edge, or from the point of discharge to any surface water. Stabilization should be completed within 24 hours of connecting to a surface water.

  • Stage Construction – If 10 miles of road is disturbed than 10 miles worth of ESCM’s must be incorporated, inspected and maintained.


2005 construction site review cont1

2005 Construction Site Review cont.

  • It appears that specifications and permit provisions could be better enforced.

    • Inspections and reporting as defined in the permit.

    • Maintenance as defined by the permit

      • Sediment Terraces in ditch bottoms

      • Sediment not removed from water bodies resulting from deposition

    • Specifications

      • Spec. 110.05 – “When a suspension of work is ordered or when operations on the project are suspended for the winter, the Contractor shall take all action necessary to control erosion, pollution and runoff during the shutdown period before the Department accepts responsibility for maintenance.”

      • Grading is being performed for entire length of project at one time. See Spec. 110.05 for the limits of disturbance relating to clearing and grubbing.


Memorandum of agreement between nddot and nddoh

Memorandum of Agreement between NDDOT and NDDOH.

  • No signature required on permits from the NDDOT. NDDOT is the owner and ultimately liable.

  • Identifies contractors as the responsible parties for obtaining and ensuring permit compliance as defined in the permit.

  • Rainfall waiver for eastern 1/3 of state to allow consistent stabilization and permit closure.

  • Waiver for non-contiguous projects over 1 acre.

  • NDDOH can reactivate a permit (in whole or in part) for a period of three years after final stabilization, if a stabilization method other than 70% pre-existing vegetative cover is selected.
