EPA seeks new truck pollution rules; says air won't suffer

The Trump administration's Environmental Protection Agency is proposing to rewrite rules that limit pollution from heavy trucks but that the EPA says slow the economy.

Acting EPA Administrator Andrew Wheeler argues that new technology can help improve air quality, noting that the regulation of harmful nitrogen oxide emissions hasn't been revamped since 2000.

EPA officials were to announce the plans Tuesday but offered few details and said they were just beginning a regulatory process that can take years.

The proposed initiative is drawing expressions of hope but skepticism from some environmental groups, especially because the EPA under President Donald Trump already has proposed relaxing emissions requirements for light passenger cars and trucks by freezing them at 2020 levels.
