Momentum Is Building for Street Sweeping's Water Quality Case
by Ranger Kidwell-Ross, editor
WorldSweeper.com
If you've followed this newsletter for any length of time, you know the drumbeat I keep coming back to: street sweeping is the first line of defense for protecting water quality. It's been the central message of everything I've written since my days founding American Sweeper magazine in the early 1990s, and this issue gives me more reasons than usual to keep beating that drum.
Start with the Chesapeake Stormwater Network's crediting program. Streets make up a significant share of the impervious cover in the Chesapeake Bay watershed, and the Network has now laid out exactly how communities can earn credit toward the Bay's pollution diet based on their sweeping schedules and equipment types. That's the kind of concrete, usable framework our industry has needed for years – not just an acknowledgment that sweeping helps, but a formula for proving it.
Minnesota is doing the same thing from a different angle. The state's Pollution Control Agency has rolled out a Street Sweeping Credit Calculator that lets cities convert the weight or volume of collected sweeper waste into documented reductions of total phosphorus. If a program like this doesn't yet exist where you operate, make sure your state's stormwater staff know it's out there. Programs like Minnesota's and Chesapeake's are exactly what turns sweeping from a nice-to-have amenity into a compliance tool that MS4 permit holders actively need.
That's also the driving idea behind the Clean Streets = Cleaner Waters Initiative from the National Municipal Stormwater Alliance. Seth Brown and Greg McPartlin are leading the initiative, and Roger Sutherland, Dr. Andrew Sheerin, and I have been working on promoting it for our Stormwater Week talk. We will be outlining what the initiative is after: credible technology-verification standards, more consistent regulatory credit for sweeping programs, better pollutant-capture metrics, and wider recognition of what trained sweeper operators actually contribute to pollution reduction. Workshops open for signup September 1st at StormwaterAwareness.org, and I'd encourage anyone serious about the crediting conversation to be there.
On the enforcement side of things, New York City has brought back its fluorescent "you're blocking a sweeper" windshield sticker after more than a decade off the streets. Love it or find it heavy-handed, DSNY's data says the visible public reprimand – paired with the $65 fine – actually changes driver behavior. It's a reminder that all the water-quality science in the world doesn't matter much if sweepers can't get to the curb in the first place.
In San Antonio this November, TYMCO returns as title sponsor of the 15th Annual Sweeper Summit, with an Outdoor Equipment Expo, ride-alongs, and the kind of after-hours networking that's quietly launched more good ideas than any seminar on the schedule.
On the equipment front, Nitehawk's new Raptor Electric Hybrid caught my eye – the company reports a 38% efficiency gain along with lower emissions and quieter operation, which matters more every year as cities push for cleaner, less disruptive sweeping on residential and night routes.
Taken together, this issue reflects where the industry is headed: better data, better credit, better enforcement, and better equipment, all pointing toward the same conclusion I've been arguing for over three decades – sweeping earns its keep.
As always, if you have questions and/or any news of potential interest to the power sweeping community, please let us know. Between this publication, the WorldSweeper.com website, and the World Sweeping Association, we'll be sure to get the information passed along to interested readers.

Chesapeake Offers Credits for Street Sweeping With the Goal of Bay Restoration
Convening knowledge, people, and best practices dedicated to stormwater management and restoring the Chesapeake Bay.
Streets represent a significant fraction of total impervious cover in the Chesapeake Bay
watershed, as they do in many areas of the US. Street cleaning can be an excellent strategy to reduce the toxic inputs from urban watersheds, given the high level of toxic contaminants found in both street solids
and sweeper wastes.
Nearly all Chesapeake Bay communities operate some kind of street sweeping program in order to
improve aesthetics and meet public demand. When those communities receive further information about how existing
sweeping programs can provide a water quality benefit to help meet the 'Bay
pollution diet,' strides can be made in keeping Chesapeake Bay – and YOUR bays and other waterways – more pristine.
Use the PDF link to the organization's Fact Sheet on Street Sweeping to learn how the organization classifies the various types of sweepers and also details how Chesapeake Bay communities can now earn credits for differing sweeping schedules using different types of sweepers.

Clean Streets = Cleaner Waters Initiative
The National Municipal Stormwater Alliance’s Clean Streets = Clean Waterways initiative is based on the established role of enhanced street sweeping as a first line of defense against stormwater pollution. Seth Brown and Greg McPartlin are leading the initiative at NMSA. Roger Sutherland, Ranger Kidwell-Ross, and Dr. Andrew Sheerin will outline the work underway to strengthen street sweeping’s effectiveness and recognition as a practical stormwater-management tool.
Key priorities include establishing credible technology-verification standards, creating more consistent regulatory credit for sweeping programs, and increasing awareness of the value that trained power-sweeper operators bring to pollution reduction. The initiative also aims to develop practical pollutant-capture metrics; advance technologies that simulate, prioritize, and optimize sweeping routes and operations; encourage holistic non-structural stormwater programs; and collect and share the research and data needed to support effective, science-based street-sweeping practices.

Minnesota Pollution Control Agency Offers Street Sweeping Credits to MS4s
Minnesota now offers a 'Street Sweeping Credit Calculator' that cities in the state can use to determine the amount of credits they can receive as a result of their sweeping programs. The Calculator presents various street sweeping crediting methods that rely on mass and volume conversions of wet or dry material to calculate an estimated reduction of total phosphorus (TP). The crediting methods include a dry mass-based measurement, wet mass-based measurement, and volume measurements using both determined and default bulk densities.
All crediting methods require the initial measurement of the weight or volume of street sweeping waste collected during sweeping efforts. Wet mass can be used to determine TP reduction credits with known TP concentrations in wet street sweeper waste. The credit is determined by applying conversion factors to the weight of freshly collected material (wet). The product of the weight of material collected and the conversion factor is the mass of phosphorus removed.
If this type of program is not yet available in your state, make sure your state's stormwater program professionals are aware of what is available elsewhere. By implementing this type of system, the credits needed to confirm a higher level of stormwater permit compliance become available to participating cities, many of who need them in order to get into compliance.
Check out what Minnesota now offers for credits due to street sweeping.
NYC: 'You're Blocking a Sweeper' Sticker Makes a Comeback
New York City's Department of Sanitation (DSNY) has revived the fluorescent "shame sticker" – an 8.5" x 11" neon warning label slapped on the windshield of any vehicle that fails to move for street sweeping. The bright shield-shaped stickers had been banned by the City Council in 2011-2012 after complaints that the old adhesive was too aggressive and damaged car windows.
The stickers were originally used for about 25 years before the 2012 ban, and DSNY data indicates they genuinely change driver behavior – the visible public reprimand, combined with the accompanying $65 fine, deters people from leaving cars parked through cleaning hours. Brewer has been vocal about deteriorating street conditions, noting she personally coordinates a monthly cleanup with sanitation crews and NYPD on West 83rd Street because so many drivers ignore alternate-side-parking (ASP) rules.

The StreetSweeper Movie Makes a Comeback
The StreetSweeper movie is making a comeback! James Hill, the producer of the project, said his organization has received funding to reshoot some of the scenes. Specifically, these are ones that involve the sweeper interacting with a homeless encampment. Those scenes will be reshot later this month. Then, they expect to have a wider release of the movie than what it had before since so much interest has been generated since there are so many homeless people now in the US.
Because the movie is about street sweeping, Hill is offering through WorldSweeper 5,000 FREE crypto coins to anyone in power sweeping. It's a wide-ranging gift that you may also offer to other members of your business employee and family group! To see how to download the info you need to take advantage of the free crypto coins, use the link shown below.
