The resistance there has been largely divorced from the national debate around the president’s immigration policies. Instead, residents cite a raft of local concerns — water, sewer, health care and emergency response systems that could be overwhelmed.

And because the federal government typically doesn’t pay local property taxes, many in the broader area fear that school districts and municipalities would miss out on hundreds of thousands of dollars in revenue they might otherwise have received from a private land owner. (Although the warehouse was not in use, the previous owner was still paying taxes.)

Justin Moeller, a Republican who is the borough’s mayor and assistant fire chief, estimated that 60 percent of his constituents were against the facility. Tremont Borough, where most area residents live, is separate from Tremont Township, a municipality that abuts it and where the warehouse is located. The two share infrastructure and resources, meaning the detention center’s impacts would resonate across both.

The manner in which D.H.S. purchased the warehouse, without seeking input from residents, has also struck a nerve.

“Don’t just throw it in our backyard and say, ‘This is where it is, now you got to deal with it,’” Roger Adams, a former mayor of Tremont who is now on its borough council, said in an interview in March. “That’s not the way I do business.”

Events unfolded almost identically in Berks County, where D.H.S. bought a warehouse for use as a processing center. Michael Rivera, a Republican commissioner for the county, said it seemed as if D.H.S. wanted to pre-empt in Pennsylvania the kind of pushback that has killed warehouse sales elsewhere.

Immigration and Customs Enforcement, which would run the facilities under D.H.S., says that these centers would benefit local communities economically, including by bringing in thousands of jobs. And many Trump supporters in the area remain unwavering in their backing of his immigration crackdown.

At a fiery Schuylkill County Board of Commissioners meeting in March, Robert Caputo, a county resident, approached the lectern to say he was “sick of” illegal immigrants in the community, and he felt something had to be done.

“They should be in detention and shipped back to their country,” he said.

D.H.S. officials also say creating new detention centers would allow the agency to move away from using privately operated prison companies. There are reservations within D.H.S. about whether private prisons can deliver on Mr. Trump’s deportation promises, which would require over 100,000 beds, according to a U.S. official who asked to remain anonymous because the person is not authorized to talk about the planning. The agency currently detains around 60,000 immigrants nationwide, the official said.

Gov. Josh Shapiro, a Democrat, who both opposes the immigration crackdown and questions the choice of these sites, vowed at a February news conference to use “every tool at my disposal” to stop the warehouse plans, including the withholding of essential permits if D.H.S. does not comply with state environmental laws.

Some local Republican leaders seem content to let Mr. Shapiro fight the federal government, taking an official non-stance on the detention center, even as they voice similar reservations.

“If the governor thinks he can stop it, that’s on the governor’s level,” Larry Padora, a Republican who chairs the Schuylkill County Board of Commissioners, said in an interview. “My job is to make sure that if this facility comes here, that my residents and my taxpayers aren’t left holding the bag.”

Despite the state’s demand for information, D.H.S. has yet to provide detailed plans on how it will supply water, health care and a functional sewage system for its detainee population. What little has been revealed has come from conference calls between local leaders and D.H.S. officials arranged by the area’s congressman, Dan Meuser, a Republican.

In March, roughly a hundred people attended a town hall hosted by a local opposition group, seeking more answers.

To many of those gathered, D.H.S. seemed like just the latest outsider to treat Schuylkill County as a dumping ground. After the decline of the local coal industry, multiple landfills sprang up around the region. In the last several years, residents say, odors from a biosolids plant that processes treated domestic sewage have rendered the air so fetid at times that they won’t step outside.

There could be more of that, local leaders fear, if the detention center opens. Mr. Padora said that D.H.S. has proposed trucking out human waste to avoid overburdening the area’s sewage system.

“We actually have experience with trucks driving down our streets with human sewage, and it’s spilling out of the truck,” Joe Wiscount, a Tremont resident who helped organize the town hall, said of the borough’s experience with the biosolids plant.

“We don’t want more of it dumped on us,” he added.

Joyce Wetzel, 60, who has run a day care next door to the warehouse for decades, said she broadly supported the president’s immigration policies. But she worried about the possibility of escaped detainees or protests, and about the parents who say they’ll pull their kids out of her facility if the detention center opens.

Most people in ICE detention do not have criminal records. However, as existing detention centers have grown more crowded under the Trump administration, tensions inside — and, at times, outside — of them have mounted.

“I’d like to retire someday soon, put a for sale sign on,” Ms. Wetzel said of her day care in an interview. But if the detention center moves forward, she wonders, “Who’s going to buy it?”

Once all the residents spoke, Mr. Padora, one of several local leaders present, shared what he had learned from the county’s meetings with D.H.S. The agency seemed amenable to some of the county’s requests, he said, including payments in lieu of lost tax revenue, and making the detention center open for inspections by the local authorities. Mr. Padora said he would wait to see its promises in writing, however.

Many in attendance seemed skeptical that anyone in the room could prevent the detention center from opening.

“We can have our little groups and we can sit and complain about it,” Mr. Pribilla, the hardware store owner, said the next day. “But how much power do we actually have to stop the federal government?”
