Make sure they deliver the proper rate of water and shut-off <br />automatically when not in use. <br />d) For wash areas that are plumbed to a sanitary sewer, clean the sewer inlet at least <br />weekly. <br />e) Inspect all fueling equipment and fuel islands at least daily for leaks, drips, <br />corrosion, wear, or damage. Repair or replace all faulty equipment promptly. <br /> Routine Street and Parking Lot Sweeping <br />Responsible Party: Streets and Stormwater Supervisor <br />Regular street and parking lot sweeping (using sweeper trucks/equipment) removes debris, <br />such as dust and pollutants, which typically end up in streams after being washed into catch <br />basins. Sweeping should be performed at least twice a year on all roads and preferably more <br />in areas of concern, including near streams, land use (industrial areas vs. residential) or heavily <br />trafficked areas. <br />1. Operate all sweepers according to the manufacturer’s recommended procedures. <br />2. Develop a street sweeping schedule including prioritized roads, secondary roads and <br />frequency of sweeping. <br />3. Schedule sweeping as follows: <br />a) In areas where storm drain plugging or high pollutant loadings occur. <br />b) Immediately following special events like street fairs, art shows and parades. <br />c) Immediately after street repair projects that involve saw cutting, chip sealing or <br />other operations that might have left wastes or debris on road surfaces. <br />d) After leaf collection in the fall. <br />e) After salt/sand application in the winter. <br />f) During new construction projects involving temporary storage of construction <br />materials like dirt, sand and road base along the roadway. <br />g) Immediately following median grass cutting operations. <br />4. Make sure brushes and water spray hoses are functional before leaving the shop. <br />5. Clean out solid debris and store in an impervious area or in a temporary disposal area <br />such as a truck or dumpster. <br />6. Scrape out left over debris from the hopper after the last dump of the day. Dispose of <br />waste in trash or dumpster temporary storage area. <br />7. Always wash sweepers in a wash area or wash bay that drains to a sanitary sewer. <br />8. Avoid conducting sweeping operations during rainstorms. <br /> Emergency Response <br />Spill prevention and response is one of the most important Good Housekeeping Practices for <br />municipal operations. During daily activities, municipal employees handle, transport, load, <br />and use products that can be harmful to our waterways if they enter storm drains. Refer to <br />the Illicit Discharge Detection and Elimination Plan for the Spill Response Plan. <br /> Cleaning of Maintenance Equipment, Building Exteriors and Dumpsters
