WASHINGTON — The Environmental Protection Agency has signed a contract for nearly $25,000 to build a soundproof communications booth for the office of the administrator, Scott Pruitt.

The contract, with Acoustical Solutions in Richmond, Va., was first reported by The Washington Post. It calls for the construction of a $24,570 “privacy booth” for Mr. Pruitt’s office.

Liz Bowman, a spokeswoman for the E.P.A., did not return requests for comment on the contract. In a statement to The Post, she said agencies needed to have such booths to guard against hacking and eavesdropping. “This is something which a number, if not all, Cabinet offices have and E.P.A. needs to have updated,” she said.
