Make sure the aftertreatment device you select has the appropriate verification, if required. For example, Volvo has formed a supplier partnership to provide EPA and California ARB verified particulate trap retrofits for its construction equipment. (Tier 0 machines will require special attention, since they get into high hour accumulations, which can impact the application of retrofit devices.)
"The Volvo particulate traps carry a Level 3+ verification, which is the highest level possible, collecting over 99% of PM and producing no additional NO2," says Bartz. "PM is getting more and more attention these days, with California and New York City retrofit regulations written specifically around reducing PM. There is a significant emphasis on NOx also, but no verified solutions currently exist that substantially reduce it."
Turn to distributors
As California and other states in non-attainment areas (notably states in the Northeastern U.S.) adopt tougher emissions laws, other states are likely to adopt them, as well.
"Unfortunately, this makes it complicated for larger customers who operate in many regions, as the rules may be different in each location," Readey notes. "This is the reason Caterpillar Emissions Solutions has emission territory managers located throughout the U.S. This way, we have greater focus as to what is going on in each region, and can work with the local dealers to bring the best solutions for the customer."
He adds, "Many contractors don't have the staff to follow all that is happening in the regulatory world. [Our role] is to take some of that burden off their shoulders and do that homework for them."
John Deere dealers have taken a similar approach. "Our dealers are working a lot with customers to manage their fleets, because they have to report now, especially in California," says Mastanduno. "So they have to go through every machine and figure out what tier it is, and all of that information has to be reported."
The dealers also play a key role in helping customers locate and receive available government funding to defer compliance costs. According to Mastanduno, there is government funding available to help fleets come into compliance with local regulations, but the application process can be long and complicated. In this case, the John Deere dealers have become expert resources to help customers apply for and receive the money available.
"It is not just providing the aftertreatment or the repowers, it is also fleet management and coming up with emissions solutions," says Chrusciel. "The dealers are an integral resource for the contractor. They are out there on a local basis. They have a lot of technical capability to install retrofit devices and help manage the fleet. They have the information the contractor needs to make difficult decisions regarding the most economically feasible solutions.
"At the end of the day equipment owners are not only asking themselves how they can comply with the rules. They are also asking what the best economic choice is. Should I repower or retire the machine and replace it with something new, or do I need an aftertreatment device? It is all about the economics."
