Bismarck Stormwater Laws and Regulations

Excerpt- City of Bismarck Storm Water Plan for compliance with EPA Phase II Storm Water Rules and Regulations

In order for the City of Bismarck to achieve compliance with the EPA Phase II Storm Water Rules and Regulations that will go into effect in 2003 the city has developed a Storm Water Plan. EPA guidelines address six (6) areas that need to be addressed with the City’s Storm Water Plan. These six areas are Public Education and Outreach, Public Participation / Involvement, Illicit Discharge Detection and Elimination, Construction Site Runoff Control, Post-Construction Runoff Control, and Pollution Prevention / Good Housekeeping. The following narrative outlines a plan developed to address Minimum Control Measures for each of these six areas. Measurable Goals, which are required for each of the Minimum Control Measures, are intended to gauge permit compliance and program effectiveness. The narrative addresses activities which will be required by the City in the form of public information and education, education of the City staff, maintenance procedures, recommendations for new or modified construction standards for the City, recommendations for additional or modified City ordinances, recommended measurable goals, and timetables for the attainment of the goals within each area. The city will work with other public entities within the MS4, including Bismarck State College, United Tribes Technical College, North Dakota State Capitol Grounds and the North Dakota Army National Guard facilities to assure that they adhere to the requirements of the city’s ordinances Post Construction Runoff Control. To comply with the minimum control measures for Post-Construction Runoff Controls the City must:

1. Develop and implement strategies which include a combination of structural and/or non-structural best management practices (BMPs).
2. Develop an ordinance or other regulatory mechanism requiring the implementation of Post-Construction Runoff Control.
3. Ensure the adequate long-term operation and maintenance of said controls and determine appropriate best management practices and measurable goals for these minimum control measures. To address these minimum control measures the City recommends the following:
   1. Through proper planning and zoning controls develop guidelines for growth around sensitive areas and areas which are considered undevelopable.
   2. Develop BMPs for post construction runoff water quality control as appropriate.
   3. Revise existing ordinances to address water quality issues from developing and redeveloping areas.
   4. Expand the inspection authority of the City staff to include the inspection of post construction runoff control and have them properly trained to perform these activities. Develop a tracking and reporting process for each site inspection.
   5. Develop long-term operation and maintenance of BMPs installed as a result of existing and proposed ordinances.
   6. Develop an education and training program to address the need for post construction site runoff water quality control. This information would be developed to address both the needs of the general public as well as City staff. The City will determine what information will be distributed and the best means of providing this information to the public and City staff.
