Mail service was expected to resume regular operations at a Dallas-area postal sorting facility Monday after a mercury spill last week caused disruptions that led to mail delays in the Tyler area.

The Dallas Morning News reported about 4 gallons of mercury spilled at the North Texas Processing and Distribution Center Aug. 7 in Coppell.

That facility sorts mail headed to the Tyler area.

Hazmat teams contained the spill, but the center was closed and its operations were sent to other facilities in the immediate aftermath.

A spokesman for the U.S. Postal Service did not specify to the Morning News why the mercury was at the center, but described it as part of a “mailed package.”

No one was injured in the incident.

Because of the extra burdens placed on other distribution centers as a result of the spill, some packages might take longer to deliver, the postal service said in a written statement to the Morning News.

The postal service said all mail should be safe because of its handling process, and the employees in that facility have been reassigned to others.

Mail delivery to the Tyler area is expected to return to normal after the United States Postal Service got the go-ahead from the Environmental Protection Agency and USPS safety officials to return to regular daily operations.

The Dallas Morning News reported that mail delivery was delayed due to a mercury spill at the North Texas Processing and Distribution Center in Coppell, a city outside Dallas.

The distribution center is responsible for processing mail intended for Tyler and other East Texas cities.
