We need your help to keep our waterways and storm sewer systems clean and free of hazardous materials and sediment. This can be accomplished in many ways, including the following:
The Three C’s
- Control – Prevent materials from becoming mobile and entering the storm drain system
- Contain – Isolate work areas
- Capture – Clean up work areas
Other practices to implement include:
- Do not remove vegetation unnecessarily if precipitation is forecasted.
- Reestablish vegetation as soon as possible on disturbed areas.
- Utilize landscaping to control stormwater runoff. Check local requirements before implementing landscape measures.
- Plan construction activities in stages that reduce the possibility of erosion.
- Keep potential sources of pollution out of the rain to the maximum extent possible (e.g. inside a building, under a tarp, sealed in containers, etc.)
- Dispose of hazardous materials promptly and properly.
- Use fertilizers and lawn chemicals per the manufacturer’s directions. If over applied, these items can find their way into the stormwater collection system and eventually into our waterways.
- Keep pet waste cleaned up. Pet waste can be a source of E. Coli in stormwater runoff.
- Keep trash, leaves, and lawn clippings off streets and out of storm drains and ditches.
- Repair automotive leaks.
- Do not pour oil, pesticides, paint, or other materials down the storm drain. Household quantities of paint and chemicals can be taken at the City Landfill at 5176 134th Ave. NW. Paint must be solidified by either adding kitty litter or drying prior to disposal. The city oil collection site is located on the east side of 8th Ave. E., south of the 8th Ave. E. and 6th St. E. intersection.
- Wash vehicles on the lawn or in commercial washes.
If you are planning any size job that will cause soil disturbance, creating a potential for sediment or other contaminants to leave the site and potentially enter the water system, please follow the requirements and recommendations listed below.
For more information, refer to the ND Department of Environmental Quality's (NDDEQ), Homebuilder Guidelines for Erosion and Sediment Control: Sites Disturbing Less Than 1 Acre.
Prior to starting any construction projects around the yard, look for areas where stormwater can escape from the site. These are areas where best management practices (BMPs) need to be utilized to slow and control the flow of water impacted by the work area, until sediment and contaminants are no longer a concern.
These BMPs include silt fence, wattles, inlet protection (dandy bags and logs), designated holding spots so sediment can settle out, and erosion control blankets. These must be installed prior to the start of construction. Please contact the City Engineering Department or NDDEQ for more information.
During construction, inspect all BMPs on a regular schedule. The City Engineering Department recommends every two (2) weeks and after every rain event of 0.25” or more. Repair or replace damaged BMPs as needed.
In the event a BMP fails and allows stormwater to leave the site, please contact the City Engineering Department or Development Services Department immediately. A site inspection will need to be completed so any potential environmental impacts can be mitigated. We need your help to keep our waters clean and free of contaminates, so please do not hesitate to call!
Concrete trucks need a designated, protected, and lined washout pit. The washout pit should be inspected regularly with use, and must be placed in a location away from streams, storm drain inlets, and ditches. Clean out the washout pit periodically. The City Engineering Department recommends coordinating with your concrete supplier prior to delivery of concrete. Many suppliers have mobile washout pits that can be supplied as part of their service.
Practice good housekeeping during construction. Please keep your site free of litter, construction debris, and leaking containers. If you are using equipment to perform work, park it in the same place daily, and perform fueling and preventative maintenance activities in the same place to minimize the area that may become impacted in the event of a leak, spill, or overtop of fluids. Clean up any soils that come into contact with fuels, oils, grease, and other machine fluids, and dispose of them properly and promptly. Please contact Public Works for more information.
After construction, ensure the area is free of potential contaminant sources. Leftover materials must be stored properly so rain and snow melt will not cause materials to wash off the property. Leftover dirt and gravel should be hauled if you do not plan to use it during the construction season. Many gravel suppliers and contractors will take these materials for free if you haul it, or may charge a fee for hauling and loading. If you want to keep leftover gravel or dirt onsite, it must be protected with a BMP until it is used or removed from the site. Concrete washouts must be cleaned up and cannot be left on site. The hardened concrete material can be taken to the City Landfill. Other leftover materials such as grout and paints should be stored inside.
BMPs must remain in place until vegetation is established or the area is hard surfaced with a material not susceptible to eroding or tracking out onto the streets, as allowed by ordinance. Please maintain and repair the BMPs during this time. Once vegetation is established, or the area is hard surfaced, please remove and dispose of the BMPs properly. They can be disposed of at the City Landfill or placed in your garbage. Any recyclable materials can be taken to the City Recycling Center located at the northeast corner of University Avenue and 1st Street East.
