Redford also said he was going to try to meet with Interior Secretary Ken Salazar while he was in Washington promoting his new film, "The Conspirator."
The movie premiered at Ford's Theatre Sunday night, although it would have needed to move locations if Congress and the White House had been unable to come up with a deal to fund the rest of fiscal year 2011.
Ford's Theatre is part of the National Park Service, which would have shuttered along with the rest of the government.
The six-month federal spending deal reached late Friday night did not include GOP-backed plans to thwart several EPA rules. But opponents of EPA climate change rules and other regulations are seeking other vehicles to delay or nullify the controls.
A bill that strips EPA's power to regulate greenhouse gases passed the House last week.
