   The purpose of this procedure is to establish guidelines for the maintenance of stormwater management facilities installed on campus.
   
   
2. DEFINITIONS
   
   Stormwater Management Facility - a device that controls stormwater runoff and changes the characteristics of that runoff, including but not limited to, the quantity and quality, the period of release, or the velocity of flow.
   
   
3. RESPONSIBILITIES
   
   
   1. Director of Facilties Management is responsible for the overall implementation of this procedure.
      
      
   2. Assistant Director of Facilities Management for Operations and/or Service Managers are responsible for ensuring that stormwater management facilities are properly inspected and maintained in accordance with this plan and shall issue periodic or repetitive work orders for specific inspections as necessary.
      
      
   3. Project Manager is responsible for ensuring that stormwater management facilities are installed in accordance with the Department of Conservation and Recreation requirements.
      
      
   4. Engineering Manager is responsible for submitting the annual report.
      
      
4. PROCEDURE
   
   
   1. The inspection and maintenance of stormwater management facilities shall be in accordance with Virginia Stormwater Management regulations.
      
      
   2. Each stormwater management facility shall be inspected on a semi-annual basis and after any storm which causes the capacity of the facility to be exceeded. The Project Manager shall initiate a scheduled work order upon the completion of construction to accomplish this inspection. The inspection shall include the following items as a minimum:
      
      
      1. Clean facility as necessary to maintain design volumetric capacity.
         
         
      2. Inspect facility inlets and outlets for any blockages and clean as necessary.
         
         
      3. Inspect facility structures for any signs of deterioration and correct as necessary. Special attention to the Newman Lake spillway: Operate spillway gate three times annualy to assure proper function. When ground is saturated and additional and/or significant precipitation is expected, the spillway water gate shall be opened and the lake surface level lowered in anticipation of exceptional surface water run-off from watershed areas above the lake.
         
         
      4. Note all inspection findings, date, name, and location on the inspection work order.
      
      
      
   3. The Engineering Manager shall submit an annual report to the Department of Conservation and Recreation, Division of Soil & Water Conservation Regional Office. The report shall include the following information:
      
      
      1. Location

      3. The affected waterbody, watershed or basins.
         
         
      4. Summary of any water quality monitoring data associated with these facilities.
         
         
      5. A copy of this report will be kept in the Engineering Department file.
      
      
      
   4. This procedure shall be reviewed annually.
