The head of the Environmental Protection Agency is telling staff to quickly finish up the last round of regulations before President-elect Donald Trump enters the Oval Office next year.

"As I've mentioned to you before, we're running — not walking — through the finish line of President Obama's presidency," EPA Administrator Gina McCarthy said in a staff memo obtained by the Washington Examiner after Trump was declared the winner of Tuesday's election.

The agency is currently working on regulations for the oil and gas sector, and is finalizing new annual regulations for the nation's ethanol mandate and renewable fuel blending requirements. The agency is also moving rules related to implementation of its landmark Clean Power Plan for cutting carbon pollution from the nation's coal utilities to combat global warming.

The Clean Power Plan itself is currently under court review after being temporarily stayed by the Supreme Court on Feb. 9 until all judicial review has concluded. Over half the nation is opposing the climate rules along with major industry groups and the coal industry. Trump has made repealing the EPA climate plan a key part of his first 100 days in office.

McCarthy thanked staff "for taking that run with me," and that she is "looking forward to all the progress that still lies ahead."

More from the memo:

With the election now over, I wanted to take a quick moment to touch base with all of you about next steps. While this is always a time of reflection for our country, it is also a time to renew our agency's commitment to protecting public health and the environment. It is always important to remember that the work we do as an agency and our core mission reflect the values of the public we serve, and that will always be the case.

Whether it's creating new standards to address climate change or protect the air we breathe, enhance support for programs that detect and reduce water pollutants, or extend our outreach efforts to local communities, everything we have accomplished together has served to advance our important mission of protecting public health and our precious natural resources. We should all be proud of the accomplishments we have made together over the past eight years while keeping in mind the work we need to complete in the weeks ahead that is so important to both EPA's mission and the legacy of this Administration.

President Obama has made it clear that a seamless transition is one of his top priorities, and I share his goal. Soon, you will receive an email from [EPA Chief of Staff] Matt Fritz about next steps. As many of you know, we have a process in place at EPA to make sure this transition runs smoothly and seamlessly."

I look forward to continuing our momentum together. As I've mentioned to you before, we're running — not walking — through the finish line of President Obama's presidency. Thank you for taking that run with me. I'm looking forward to all the progress that still lies ahead."
