The project initiated from the City of Pomonas on-going goal of providing a quality City service and developing safe, clean, family oriented neighborhoods. The City of Pomona recognizes that heavy-duty on-road motor vehicles which are operated by the City contribute to the general emissions of the local, regional, and global air quality. With this in mind, the City of Pomona has and will continue to put forth efforts to promote, and implement the use of low-emitting on-road motor vehicle technologies. The purchase of two CNG regenerative air sweepers was primarily motivated by poorly functioning, and outdated, street sweepers, which operate on a daily schedule. This equipment was found to be an excellent candidate for replacement. The sweepers are responsible for sweeping approximately 593 curb miles throughout the City on a bi-monthly schedule.

Implementation The City of Pomona, in collaboration with the City and County of San Francisco, received special pricing and a pre-assembled purchasing specification for the purchase of two CNG regenerative air sweepers. The City and County of San Francisco recently composed a particular specification bid package to create the most optimal and cost effective CNG regenerative air sweepers, and awarded the contract to a vendor that could produce the vehicle. The use of the City and County of San Francisco bid drastically reduced the lead time involved in creating, bidding, and implementing this project. The City of Pomona was able to implement the project and remove the old diesel fueled street sweepers months ahead of schedule. Status The street sweepers have been in operation within the Street Sweeping Program since April 2006. Between the two CNG regenerative air sweepers they have covered approximately 26,000 curve miles within the City of Pomona. They only operate within the City of Pomona boundaries. The new sweeper units perform more efficiently, and at a lower emitting level than the sweepers they replaced. The two CNG regenerative air sweepers were received in March 2006. The two street sweepers replaced were sent to auction immediately after receiving the new sweepers.
The objective of this project was to purchase and successfully implement two new CNG regenerative air sweepers and replace two high-emitting, outdated, diesel fueled equipment from the City fleet circulation.
There has been a considerable emissions reduction because of the implementation of more modern low-emitting, on-road, motor vehicle technologies that are now available. The vehicles which have now been replaced were both 1986 Tymco Regenerative Air Sweepers, which were diesel fueled and had high mileage. The new sweepers are overall much faster and efficient.
