The so-called omnibus would deliver a $143 billion spending boost across defense and domestic programs — the largest funding bump in recent years.

The House could vote as soon as Thursday on the 2,232-page bill, which is packed with dozens of long-simmering policy items on Capitol Hill:

What’s in:

— Money for the Gateway tunnel, with a catch: The deal would provide $650 million to Amtrak for capital projects along the Northeast Corridor, but any money Amtrak may try to direct toward the massive Gateway project under the Hudson River could need DOT approval. The Gateway project was initially slated to receive $900 million in federal funds.

— Border security and wall: The bill would provide nearly $1.6 billion for border security, but not for an increase in detention beds or federal deportation agents, a key priority for Democrats in the talks. The deal includes roughly $641 million for new physical barriers, which GOP leaders have called the “border wall project”, instead of the $18 billion Trump had sought for the wall. Republicans say it provides for more than 90 miles of “border wall system,” beyond Trump’s request of 74 miles in fiscal year 2018. Democrats point out that only half of the fencing is for “new barriers” and the rest is for “upgraded” existing barriers.

— ‘Grain glitch': The Republican measure, favored by House Ways and Means Chairman Kevin Brady (R-Texas) and ag-state lawmakers, fixes a loophole in the GOP tax law that allows farmers to get big tax cuts by selling directly to co-ops.

— Low-income housing: In exchange for the grain glitch fix, Democrats won provisions expanding a tax subsidy for affordable housing — designed to shore up the low-income housing tax credit in the wake of the GOP tax law.

— Fix NICS: The bipartisan bill offers financial incentives for federal and state authorities to comply with the U.S. criminal background check system. It rejects conservatives demands for an expansion of “concealed carry” laws alongside that measure.

— School safety bill: The bipartisan school safety bill would create a $50 million-a-year grant program for training to recognize signs of gun violence. It’s led by Rep. John Rutherford (R-Fla.) in the House and Sen. Orrin Hatch (R-Utah) in the Senate.

— Election security: State election officials would get $380 million in technology grants to upgrade their equipment to ward off digital attacks ahead of November’s midterm elections. The FBI’s budget to fight Russia cyberattacks would also see a boost.

— ‘Fire borrowing’ fix The agreement creates an emergency pot of money for the U.S. Forest Service to use when it exceeds its fire-suppression budget, so federal agencies no longer have to dip into money earmarked for firefighting and prevention.

— Rural broadband: The bill has $600 million for a new pilot program within USDA aimed at rural broadband, in addition to existing USDA broadband loan and grant programs.

— FAA extension: Lawmakers included a six-month extension for the FAA reauthorization, which expires March 31.

— Tip-pooling language: A compromise between Sen. Patty Murray (D-Wash.) and Labor Secretary Alexander Acosta would prohibit employers from stealing workers’ tips under a proposed DOL rule that would allow the redistribution of tip money to back-of-house workers.

What’s out:

— Border wall: Republicans wanted to devote at least $1.6 billion to begin construction on President Donald Trump’s border wall, though Trump had sought $18 billion. Democrats demanded other conditions.

— DREAMers: GOP leaders demanded that any deportation relief for young undocumented immigrants, known as DREAMers, is kept out of the spending bill.

— Obamacare stabilization: A bipartisan group of lawmakers fought for money for programs like cost-sharing subsidies and reinsurance to help avoid huge insurance premium hikes this fall.

— Internet sales tax: Rep. Kristi Noem (R -S.D.) pushed for states to collect sales tax from a national sales tax on online retailers, though it has run into fierce conservative opposition. Rep. Patrick McHenry (R-N.C.), the House’s chief deputy whip, signaled on Tuesday that Noem’s measure won’t be included in the omnibus and hasn’t had enough vetting.

— Medicare Part D coverage gap: Drugmakers pushed Congress to lower their share of a drug’s costs in the coverage gap phase of Part D to 60 percent.

— Joint employer: Language to narrow the legal definition of joint employment was nixed.

— Sexual harassment overhaul : Both parties had once hoped to include a broadly bipartisan plan to overhaul Congress’ antiquated workplace rules.

— Tribal lands exemption: Republicans have sought language exempting Native American tribal lands from U.S. labor laws. Rep. Todd Rokita (R-Ind.) and Sen. Jerry Moran (R-Kansas) led the push.

— Yucca Mountain: House Republicans wanted funding to advance the stalled Yucca Mountain nuclear waste project in Nevada.

— California’s dam project: House Majority Leader Kevin McCarthy is pushing language to allow the Shasta Dam project to move forward over Gov. Jerry Brown’s objections.

— Johnson Amendment: Some Republicans want to scrap a provision in the tax code barring churches and other nonprofits from endorsing or opposing political candidates. Trump has repeatedly vowed to repeal it.

— Flood insurance: The bill would extend funding for the National Flood Insurance Program until July 31.

— Yazoo funding: Senate Appropriations Chairman Thad Cochran (R-Miss.) has long pushed for a pricey Corps of Engineers project in the Mississippi Delta. The provision was included in a draft spending bill from Cochran’s committee.

— Ex-Im Bank: Some Republicans want to lower the required threshold of members for the Export-Import Bank to approve large loans. The seven-member board has consistently lacked a quorum.
