$1 Trillion Infrastructure Bill Pours Money Into Long-Delayed Needs

WASHINGTON — Amtrak would see its biggest infusion of money since its inception a half-century ago. Climate resilience programs would receive their largest burst of government spending ever. The nation’s power grid would be upgraded to the tune of $73 billion.

The sprawling, $1 trillion bill that the Senate took up on Monday — a 2,702-page bipartisan deal that is the product of months of negotiating and years of pent-up ambitions to repair the nation’s crumbling infrastructure — would amount to the most substantial government expenditure on the aging public works system since 2009.

It is also stuffed with pet projects and priorities that touch on nearly every facet of American life, including the most obscure, like a provision to allow blood transport vehicles to use highway car pool lanes to bypass traffic when fresh vials are on board and another to fully fund a federal grant program to promote “pollinator-friendly practices” near roads and highways. (Price tag for the latter: $2 million per year.)

The measure represents a crucial piece of President Biden’s economic agenda, and the agreement that gave rise to it was a major breakthrough in his quest for a bipartisan compromise. But it was also notable for the concessions Mr. Biden was forced to make to strike the deal, including less funding for clean energy projects, lead pipe replacement, transit and measures targeted to historically underserved communities.

Some of those provisions could be included in Democrats’ budget blueprint, expected to amount to $3.5 trillion, which they plan to take up after completing the infrastructure bill and push through unilaterally over Republican objections.

The infrastructure legislation, written by a group of 10 Republicans and Democrats, could still change in the coming days, as other senators eager to leave their imprint have a chance to offer proposals for changes. The Senate began considering amendments on Monday, with more possible in the coming days.

But the legislation marks a significant bipartisan compromise, including $550 billion in new funds and the renewal of an array of existing transportation and infrastructure programs otherwise slated to expire at the end of September.

For climate, a substantial investment that falls short of the administration’s goals.

As states confront yet another consecutive year of worsening national disasters, ranging from ice storms to wildfires, the measure includes billions of dollars to better prepare the country for the effects of global warming and the single largest federal investment in power transmission in history.

Much of the money intended to bolster the country’s ability to withstand extreme weather would go toward activities that are already underway, but which experts say the government needs to do more of as the threats from climate change increase. It also would support new approaches, including money for “next-generation water modeling activities” and flood mapping at the National Oceanic and Atmospheric Administration, which would also receive funds to predict wildfires.

The legislation also includes $73 billion to modernize the nation’s electricity grid, which energy analysts said would lay the groundwork for pivoting the nation off fossil fuels. But it contains only a fraction of the money Mr. Biden requested for major environmental initiatives and extends a lifeline to natural gas and nuclear energy, provisions that have angered House progressives.

There is also $7.5 billion for clean buses and ferries, but that is not nearly enough to electrify about 50,000 transit buses within five years, as Mr. Biden has vowed to do. The bill includes $7.5 billion to develop electric vehicle charging stations across the country, only half of the $15 billion Mr. Biden requested to deliver on his campaign pledge of building 500,000 of them.

The bill would provide $15 billion for removing lead service lines across the nation, compared with the $45 billion Mr. Biden had called for and the $60 billion water sector leaders say is needed to get the job done.

The legislation also includes more than $300 million to develop technology to capture and store carbon dioxide emissions from power plants, and $6 billion to support struggling nuclear reactors. It directs the secretary of energy to conduct a study on job losses associated with Mr. Biden’s decision to cancel the Keystone XL Pipeline.

Senators won pet projects and crucial funding for their favored priorities.

As one of the few major bills likely to be enacted during this Congress, the infrastructure measure has become a magnet for lobbying by industries across the country — and by the lawmakers whose votes will be needed to push it through, many of whom spent Monday highlighting funds for their top priorities.

For the quartet of senators who represent the legions of federal workers who use the Washington Metro — Senators Tim Kaine and Mark Warner of Virginia, and Benjamin L. Cardin and Chris Van Hollen of Maryland, all Democrats — there was a critical annual reauthorization of $150 million for the transit system over a decade.

The legislation would authorize funding to reconstruct a highway in Alaska, the home state of Senator Lisa Murkowski, a key Republican negotiator. Special funds are set aside for the Appalachian Regional Commission, a federal economic development body whose co-chairwoman is Gayle Manchin, the wife of Senator Joe Manchin III of West Virginia, one of the bill’s principal authors and a key Democratic swing vote. Mr. Manchin also helped secure funds to clean up abandoned mine lands in states like his.

The legislation would set aside millions of dollars for individual projects across the country, including $1 million for the restoration of the Great Lakes, $24 million for the San Francisco Bay, $106 million for the Long Island Sound and $238 million for the Chesapeake Bay.

It also includes $66 billion in new funding for rail to address Amtrak’s maintenance backlog, along with upgrading the high-traffic Northeast Corridor from Washington to Boston. For Mr. Biden, an Amtrak devotee who took an estimated 8,000 round trips on the line, it is a step toward fulfilling his promise to inject billions into rail.

Unspent pandemic funds and tougher scrutiny of cryptocurrency help pay for the plan.

With Republicans and some moderate Democrats opposed to adding to the nation’s ballooning debt, the legislation includes a patchwork of financing mechanisms, though some fiscal hawks have called many of them insufficient.

To pay for the legislation, lawmakers have turned partly to $200 billion in unused money from previous pandemic relief programs enacted in 2020.

That includes $53 billion in expanded jobless benefit money that can be repurposed since the economy recovered more quickly than projections assumed, and because many states discontinued their pandemic unemployment insurance payments out of concern that the subsidies were dissuading people from rejoining the work force.

The bill claws back more than $30 billion that was allocated — but had not been spent — for a Small Business Administration disaster loan program, which offers qualified businesses low-interest loans and small grants. That program has been stymied by shifting rules and red tape, and has disbursed cash far more slowly than Congress (and many applicants) expected.

Leftover funds from other defunct programs would also be reprogrammed. That includes $3 billion never deployed in relief funds for airline workers.

Marc Goldwein of the Center for a Responsible Federal Budget said that only about $50 billion of the estimated $200 billion represented real cost savings. The rest, he said, amounted to “cherry picking” numbers and claiming savings from projected costs that did not transpire.

An analysis of the legislation by the congressional Joint Committee on Taxation estimated that the legislation could raise $51 billion in revenue over a decade, while the Congressional Budget Office is expected to release projections on its overall cost as early as this week.

The legislation also includes tougher scrutiny by the I.R.S. on cryptocurrency. But a last-minute lobbying push by the industry to water down the language succeeded, resulting in a scaling back of the new requirements.

Still, the provision is projected to raise $28 billion over a decade.

New resources for underserved communities — but far fewer than the president wanted.

As the United States remains battered by both the toll of the coronavirus pandemic and an onslaught of wildfires, droughts, floods and other weather calamities, the legislation seeks to target its support toward underserved communities historically in need of additional federal support.

But while Mr. Biden had called for $20 billion for projects designed to help reconnect Black neighborhoods and communities of color splintered or disadvantaged by past construction, the legislation includes just $1 billion, half of which is new federal funding, over five years for the program. The legislation also creates a new $2 billion grant program to expand roads, bridges and other surface transportation projects in rural areas.

The bill would increase support for tribal governments and Native American communities, creating an office within the Department of Transportation intended to respond to their needs. It would provide $216 million to the Bureau of Indian Affairs for climate resilience and adaptation for tribal nations, which have been disproportionately hurt by climate change. More than half of that money, $130 million, would go toward “community relocation” — helping some Native communities move away from vulnerable areas.

It would also help improve access to running water and other sanitation needs in tribal communities and Alaska Native villages, with lawmakers determined to take care of all existing project needs.

“We are still in an extreme deficit when it comes to our tribal communities,” Ms. Murkowski said in a speech on the Senate floor, adding that the funding level was “unprecedented.” “We’ve got to do right by our Native people.”

A major investment in closing the digital divide.

Alongside old-fashioned public works projects like roads, bridges and highways, senators have included $65 billion meant to connect hard-to-reach rural communities to high-speed internet and help sign up low-income city dwellers who cannot afford it. Other legal changes seek to stoke competition and transparency among service providers that could help drive down prices.

Official estimates vary, but most suggest that tens of millions of Americans lack reliable access to high-speed internet, many of them people of color, members of rural communities or other low-income groups. That need, lawmakers said, was exacerbated by lockdowns during the pandemic that required work and schooling from home.

Mr. Biden had initially proposed $100 billion to try to bring that number to zero, but he agreed to lower the price to strike a compromise with Republicans. Democrats also fought to secure the inclusion of legislation to encourage states to develop comprehensive plans to ensure that access to high-speed internet is distributed equitably among traditionally underserved groups and educate them about access to digital resources.
