In 2003, the City of Clive became a small Municipal Separate Storm Sewer System (MS4) under the State of Iowa Department of Natural Resources (IDNR) National Pollutant Discharge Elimination System (NPDES) general permit regulations. This state regulation requires the City of Clive to establish its own Storm Water Pollution Prevention and Management Program. The permit is issued pursuant to the authority of section 402(b) of the Clean Water Act (33 U.S. C. 1342(b), Iowa Code section 455B.174 and rule 567—64.13, Iowa Administrative Code. Under the permit, the City is required to comply with a Storm Water Pollution Prevention and Management Plan which outlines areas of responsibility for the City to implement Best Management Practices (BMP’s). The Operation and Maintenance Program of the City’s Municipal Separate Storm Sewer System (MS4) are carried out through inspections, maintenance and cleaning, and street sweeping.  

Inspections

  1.  All storm water intake structures shall be inspected on an annual basis. The assessment will include cleanliness, structural stability, debris accumulation, and map accuracy.
  2. All above ground structures shall be inspected on an annual basis to verify map accuracy, cleanliness, and structural stability.
  3. Deficiencies detected during the inspection process will be documented on the department’s standard inspection form.

 Maintenance and Cleaning

Deficiencies will be prioritized and corrected as they are found through the inspection process and other activities of the department. Action required may include:

  1. Cleaning accumulated debris from the interior of intake or outfall structure. (may also include video inspection of pipe lines connected to structure)
  2. Pipe line cleaning.
  3. Updating mapping and GIS system to accurately reflect actual location.
  4. Spot repair to walls of structure.
  5. Repair of street “box out” around structure.
  6. Complete removal and reinstallation of structure.

 Street Sweeping

 All city streets shall be swept two (2) times a year. The first sweeping will occur in the spring after snow and ice control operations have ceased (approximately April). The second sweeping will be after the end of fall brush chipping, approximately the third week of October. Other street sweeping may occur as deemed necessary to remove debris from the street.

Sweeping operations shall be conducted by trained operators and will be documented. Documentation shall include sweeping hours and the amount of material removed from the street.
