A $1.4 trillion spending plan federal lawmakers advanced Tuesday includes a 16% budget increase for Chesapeake Bay cleanup efforts, according to Maryland Sen. Chris Van Hollen, who helped negotiate the appropriations bill.

House and Senate leaders agreed to spend $85 million on the Chesapeake Bay Program, an office of the Environmental Protection Agency, in the fiscal year that began Oct. 1.


The plan also includes a 3.1 percent raise for federal civilian employees. Maryland is home to tens of thousands of such workers with about 50,000 in the Baltimore region alone and many more in the suburbs around Washington.

The House approved the package Tuesday, and the Senate is expected to take it up later this week. It is expected to gain approval in both chambers, and White House adviser Kellyanne Conway said President Donald Trump would sign it into law.

“Even amidst the division in Washington, we’ve been able to work together to achieve this very positive result for the Chesapeake Bay,” said Van Hollen, who serves on the Senate Appropriations Committee.

Over his term, Trump has repeatedly proposed gutting the Annapolis-based bay program office, but in both chambers of Congress, lawmakers this year advanced increased spending for the $73 million initiative. The office guides bay cleanup efforts in the six states, plus the District of Columbia, that make up the bay watershed, and is seen as a key backstop to ensuring each jurisdiction does its part to reduce pollution.

The House proposed increasing the program’s budget to $85 million, while the Senate suggested $76 million; lawmakers ultimately agreed on the higher number over concern that population growth across the Chesapeake watershed will make efforts to reduce pollution more difficult in the coming years. A target to reduce pollution across the 64,000-square-mile watershed to restore the bay’s health by 2025 is approaching.

“We made the case that the needs of the bay had grown and this was an important time to provide additional federal resources,” Van Hollen said.

The proposal is part of a 2,300-page, two-bill package that also includes money for Trump’s U.S.-Mexico border fence, export financing, flood insurance, immigrant workers and the first installment of funding on gun violence research after more than two decades of gun lobby opposition.

It includes the permanent repeal of taxes on high-cost “Cadillac” health insurance benefits, medical devices and health insurance plans, plus pension benefits for about 100,000 retired union coal miners threatened by the insolvency of their pension fund.

The bill also would increase the age nationwide for purchasing tobacco products from 18 to 21.

The deficit tab for the package is almost $400 billion over 10 years to repeal the three so-called “Obamacare” taxes alone — with a companion package to extend several business-friendly tax breaks still under negotiation. The Obama-era taxes have been suspended on a piecemeal basis previously.
