The Environmental Protection Agency intends to drop language from a bill that could be interpreted to include strict emissions regulations for road cars converted to race use.
According to Automotive News, the EPA plans to remove wording that had been attached to a bill otherwise regulating medium and large-duty truck carbon emissions. No formal statement has been issued from the EPA, however.
The bill became controversial after the Specialty Equipment Manufacturers Association (SEMA), whose members are aftermarket vehicle modifiers, pointed out that it would prohibit modifications made to emissions systems for cars converted to dedicated track use.
The EPA, however, indicated that it had always banned tampering with emissions equipment. Its wording was aimed at aftermarket firms that sold parts to disable emissions controls, the EPA said. It should also be noted that the wording in question was in a paragraph about motorcycles and snowmobiles.
Modifying emissions controls for cars used on public roads has long been illegal, though enforcement is generally left up to states. Many states and local jurisdictions, however, do not regularly measure vehicle emissions.
The EPA faced considerable backlash from Republican lawmakers and from the public regarding the rule.
Most recently, Patrick McHenry, a North Carolina Republican, proposed a bill to dismantle the EPA's wording.
McHenry, it's worth noting, represents the home stomping grounds of NASCAR.
