Permits

1. City's Erosion/Sediment Control Permit

Standards

1.  Before commencing any land disturbing or pavement removal, the stormwater inlet(s) that receive runoff from the proposed work area shall be protected. The temporary inlet protection must remain in place until the construction activity is completed, the street has been swept and any exposed soils are stabilized. The utility contractor is also responsible for removing any temporary inlet protection they installed; after all disturbed areas are stabilized.
2. The utility contractor is responsible to ensure that sub-contractors and material suppliers comply with all erosion control requirements.
3. The utility contractor is required to inspect all erosion control devices at least once each week and after every rainfall of ½ inch or more to ensure that they are working properly. A written report of each inspection must be maintained.
4. Leakproof washout containers for concrete trucks must be provided, as applicable, on site. Containers shall be clearly marked and the location given to each driver. Containers must be properly maintained and material properly disposed of.
5. During construction activity, measures must be implemented to reduce or eliminate vehicle tracking of sediments off-site. 
• During the period of construction, impervious areas that have been tracked with sediments, or have sediments spilled or eroded onto them, must be swept and the sediments removed by the end of the day. Use of hoses and water to flush the sediments into the storm inlets is not acceptable.
6. De-watering of a site may not be discharged in a manner that causes erosion, sedimentation, or flooding on the site, on downstream properties, in the receiving channels, or in any stormwater inlet. When de-watering use one of the following methods:
   • Temporary sedimentation basins
   • Sediment bags
   • Grit chambers
   • Sand filters
   • Other appropriate controls as deemed necessary.
7. Final stabilization:
   • Within one (1) mile of an impaired water (Red River of the North) all exposed soil areas must be initiated immediately to limit soil erosion but in no case completed later than seven (7) days after the construction activity in that portion of the site has temporarily or permanently ceased. 
   • Within one (1) mile of an impaired water (Red River of the North) all exposed soil areas must be initiated immediately to limit soil erosion but in no case completed later than fourteen (14) days after the construction activity in that portion of the site has temporarily or permanently ceased.
