Pressure Systems International (PSI) is addressing the EPA’s Phase II Greenhouse Gas (GHG) initiative in this month’s Commercial Fleet Tire Digest.
PSI says the EPA is scheduled to announce its final Phase II rulemaking later this year following the completion last year’s open comment period.
“In order to reduce greenhouse gases, vehicle fuel economy of both the tractor and trailer will have incremental improvement targets over the next 10-plus years,” PSI says. “These new regulations will go into effect beginning with model year 2018. This will mean that vehicles, both tractors and trailers, built as early as 2017 must meet these new EPA regulations.”
PSI notes Phase II is especially important in regards to tire maintenance due to its focus on trailers, which had previously never been addressed by EPA emission and fuel economy regulations.
“The trailer rulemaking varies depending upon the specific type of trailers,” PSI says. “For example, for non-box trailers, which includes tankers, flatbeds and other vocational trailer configurations, only two of the many technologies will be required based on the non-finalized proposed rulemaking.”
