Through Sweeping Program Maximization The following are examples of what the Street Cleaning Workshop will address: • Why the 1982 Nationwide Urban Runoff Program (NURP) conclusions regarding the ineffective nature of street sweeping were flawed and why this matters now. • Why pavement cleaning is the most cost-effective BMP based on dollars per pound of pollutant removed from the stormwater. • Why a street sweeping program using any new sweeper will lower a local jurisdictions' costs of both catchbasin and storm line cleaning. • Why a street sweeping program using any new sweeper is much more cost-effective in removing pollutants from stormwater than end-of-the-pipe controls and why this matters. • Why several of the street sweeping studies conducted since the NURP were flawed and how this has led to poor estimates of sweeping's pollutant removal effectiveness. • Why intensive street sweeping using new sweepers of any type will be a highly desirable BMP for upcoming TMDL compliance throughout California. • Why sediment pick-up efficiencies of new mechanical sweepers are very competitive with those of both new regenerative and vacuum sweepers and why this matters. • Why sediment pick-up efficiencies of new street cleaners are much higher than those for used machines and why this matters. • Why most stormwater quality data collected since the NPDES MS4 program begun in the early 1990s is flawed and how this has led to poor estimates of sweeping's pollutant removal effectiveness. • What street sweeping studies are currently underway throughout the country, how their conclusions will likely differ from previous studies, and why this matters.
• What street sweeping studies Pacific Water Resources has conducted and why their results have shown much greater stormwater pollutant reductions from sweeping and why this matters.
Here are examples of what seminar participants will be taught at the Street Cleaning Workshop: • How to roughly estimate the stormwater pollutant loadings from California urban land uses. • How to roughly estimate the stormwater pollutant reductions associated with both existing and improved sweeping programs. • How to roughly estimate the relationship between sweeping frequency and stormwater pollutant reductions. • How to conduct sediment pick-up performance tests for street cleaners and why this matters.
• How a PWR-led street sweeping study could develop an area-specific relationship of sweeping costs to TMDL pollutant reductions and why this matters.
The information provided in these seminars will provide detailed information about the pollution reduction results from the use of power sweepers in pavement cleaning. It will be vitally helpful to anyone developing a stormwater pollution reduction plan for a municipal or other agency, as well as for contractors tasked with recommending sweeping frequency to clients. For more information, contact WorldSweeper.com's editor, Ranger Kidwell-Ross, via email or by calling 360-724-7355. You may also contact Roger Sutherland via email or by calling 503-671-9709 ext. 24. We look forward to having you join us as we provide the most informative, forward-reaching sweeper information seminars ever offered to the U.S. public works community.
