The Environmental Protection Agency awarded more than $1 million to the Port of Corpus Christi Authority. The funds go toward improving air quality by reducing emissions from in-use diesel engines. The project will re-power a 120-ton switch engine locomotive and two industrial diesel engines with anti-idling, fuel efficiency and particulate filtering technology.

Also, the EPA granted the Port of Houston Authority with almost $1.5 million. The funds are to help reduce emissions from in-use diesel engines and replace fuel switching on 21 ocean-going vessels to a lower sulfur fuel.

In another area, the EPA awarded $1.5 million to the North Central Texas Council of Governments to reduce the idling of school buses.

Other projects include efforts to reduce diesel emissions in the construction sector through the replacement, re-powering and retrofit of equipment and reduction of long-term idling of heavy-duty diesel engines.
