ROCKVILLE, Md. — Several oil tanks caught on fire late Thursday morning at a quarry in the Maryland suburbs of Washington, D.C., sending thick plumes of black smoke into the air that were visible for miles.

Oil tanks catch fire at quarry in Maryland suburbs of Washington, DC
Piringer said two of the tanks contained liquid asphalt and the third contained used motor oil.
He said the cause was not yet known.
The nature of the fire means crews can’t use water to put it out, but Piringer said they have no shortage of the appropriate chemical agents.
Piringer said that since the fire was contained, officials were focused on monitoring the air quality in communities near the Rockville industrial site. He said there was no significant health risk but residents in those areas should limit time outside and close their windows when possible.
State environmental officials were on site and all workers had been evacuated from the immediate area of the fire, Piringer said.
Rockville is about 15 miles (24 kilometers) northwest of Washington. The fire was reported just before noon Thursday.

Nonprofit sues the federal government over plans to paint Lincoln Memorial Reflecting Pool blue

A nonprofit is suing the National Park Service, the Department of the Interior and Interior Secretary Doug Burgum over the decision to resurface the Lincoln Memorial Reflecting Pool at Washington D.C.’s National Mall, and to paint the pool’s basin blue.
The suit was filed Monday in U.S. District Court for the District of Columbia by The Cultural Landscape Foundation (TCLF), an education and advocacy organization. In the suit, TCLF is asking a federal judge to halt the project, saying that the Trump administration failed to have the project reviewed federally, as is dictated by the National Historic Preservation Act.

President Trump revealed his plans for the pool do-over last month in “American flag blue,” saying that the project would take one week and $2 million, and that it would be completed in time for the 250th anniversary of the Declaration of Independence on July 4. A few days later on Truth Social, the president posted a fake image of himself and several of his administration officials in swimsuits, along with an unidentified woman in a gingham bikini, lounging in the water with the Washington National Monument at the rear. (Swimming in the reflecting pool is prohibited by federal law.)
In a YouTube video posted by the White House on April 23, Trump called the pool “filthy dirty” and said it “leaked like a sieve.” In that video, Trump said he was going to call three companies that he has worked with in the past – “all they do is swimming pools” – and say, “Give me a good price.”
The New York Times reported last Friday that the contract for the reflecting pool’s resurfacing was awarded in a $6.9 million no-bid contract to a company called Atlantic Industrial Coatings, which previously has never held any federal contracts.
An employee at the Atlantic Industrial Coatings confirmed in a telephone call on Monday that it has been contracted for this project, but referred all other questions to the Department of the Interior.
The Times reported on Monday that the final cost of the project could be upward of $13 million, per documents it says it has obtained. The Department of the Interior did not confirm the cost of the project, but wrote: “The contract price reflects the effort necessary to expedite the timeline of completing the leak prevention coating project—more people, more materials, more equipment and longer hours ahead of our 250th.”
In an unsigned statement emailed to NPR Monday afternoon, the Interior Department wrote: “The National Park Service chose the best company to expedite the repair of the iconic Reflecting Pool ahead of our 250 celebrations. The choice of American Flag Blue will enhance the visitor experience by making the pool reflect the grand Lincoln Memorial and Washington Monument. NPS is also investing in a state-of-the-art ozone nanobubbler filtration system and will now have a dedicated crew who will maintain the grounds’ from wildlife. The Department is proud of the work being carried out by our Park Service to ensure this magical spot can be enjoyed for not only our 250th, but for many generations to come.”
Critics of the project, including TCLF, don’t share that vision – and are taking particular umbrage at the color.
“The reflecting pool should not be viewed in isolation; it is part of the larger ensemble of designed landscapes that comprise the National Mall,” Charles A. Birnbaum, the president and CEO of TCLF, said in a statement emailed to NPR Monday. “The design intent, to create a reflective surface that is subordinate, is fundamental to the solemn and hallowed visual and spatial connection between the Washington Monument and the Lincoln Memorial. A blue-tinted basin is more appropriate to a resort or theme park.”
The National Park Service regularly cleans out algae, goose droppings and other detritus from the reflecting pool. The last major renovation of the reflecting pool, which included the installation of a new circulation and filtration system, took place during the Obama administration at a reported cost of $34 million.
Before founding TCLF in 2008, Birnbaum served for 15 years as the coordinator of the Historic Landscape Initiative for the National Park Service.

TCLF has another open lawsuit against the federal administration: it is one of eight cultural and architecture groups currently suing President Trump and the Kennedy Center board over the planned renovations of the complex, which are planned to start in July.

WASHINGTON D.C. – A brave K-9 hero from the region will be honored at the Annual National Police K9 Memorial Service on Monday afternoon.
K-9 Knox died in the line of duty last year after he was accidentally hit by a police vehicle while pursuing a suspect involved in a stolen vehicle incident. He was a 3-year-old German shepherd and had served as a narcotics detection and patrol apprehension K-9 for the Roanoke Police Department since May 2023.
The memorial service will include a wreath-laying ceremony and will be held at the National Law Enforcement Officers Memorial in Washington, D.C., at 1 p.m. The event will open with a musical performance by Frank Ray, and the guest speaker will be Deputy Jared Hahn of the Miami-Dade Sheriff’s Office K-9 Unit.
The San Antonio Police Department Blue Line Choir will sing the national anthem, and the Emerald Society Pipes & Drums band will also perform.
