The City of Williston is committed to keeping its waterways and stormwater system clean. To accomplish this goal, all construction work proposed within city limits must implement Best Management Practices (BMPs) such as:
The site will have a minimum number of access points possible during construction activities. Each entrance shall be constructed of wood chips, crushed rock, or concrete. All equipment, employees, deliveries, and subcontractors need to use the designated entrances.
All tracked material from the site shall be removed daily.
Silt or snow fence may be used to designate the construction area, control traffic, and limit access to and from the site.
Silt fence is to be used on all development sites to control wind and water erosion and control sediment from migrating off site. Contractors must maintain an 8ft grass buffer on the entire perimeter, if possible.
Protect all inlets that drain the site. Sandbags, fiber rolls, and other commercial inlet protection devices are all acceptable.
A concrete waste disposal area is to be provided to keep concrete waste out of the storm sewer system. The washout must be clearly marked, easily accessible, and properly maintained.
Sediment laden water cannot be discharged offsite or into the storm sewer system. A filtering system must be utilized prior to discharge. Inlet protection, grass buffer, or silt fence are not viable options of filtering.
All hazardous materials must be properly tracked and documented. Follow all MSDS guides and maintain secondary containment structures.
Sand and soil cannot be placed on or near the street or site drain way.
All construction work proposed within city limits which will cause ground disturbance of 1 acre or more must obtain the necessary Stormwater Permit(s) from the North Dakota Department of Environmental Quality (NDDEQ). Sites less than 1 acre in total disturbed area are required to implement BMPs, but are not required to obtain a NDDEQ permit.
Obtaining a Stormwater Permit
- Visit the NDDEQ and download the necessary Stormwater Pollution Prevention (SWPP) plan and Construction Notice of Intent (NOI) forms and templates for the proposed development.
- Complete and submit the SWPP plan and NOI forms to the NDDEQ:
- Submit an electronic NOI to firstname.lastname@example.org (copy the City Engineer and email@example.com) and mail an original signed copy no later than seven (7) days before construction starts; or
- Submit a NOI through the Electronic Reporting System (ERIS).
- Follow the requirements of the SWPP plan as outlined by the NDDEQ.
- At the end of construction, and prior to sending the termination notice to the NDDEQ upon completion of the SWPP plan (copy the City Engineer and firstname.lastname@example.org), contact the City Engineering Department at 701.577.6368 to schedule a site inspection.
