UPDATE: August 7, 2015
Initial tests of a powdery white substance discovered at the Boise offices of the Idaho Transportation Department on State Street, triggering a lock-down of the facility, indicated "zero toxic chemicals" but ITD officials said the powder still hadn't been identified.
Employees inside the State Street offices were asked to remain in place and people outside of the building were kept out of the facility during the incident.
The matter has been turned over to Idaho State Police to investigate.
Early reports indicate that the powder had been discovered inside a envelope on the third floor of the building.

Thursday has not been a particularly good day for officials at the Idaho Department of Transportation. Before sunrise, a power outage knocked out an underground cable in downtown Boise, including a number of government offices. That, in turn knocked out the computer systems for ITD's Division of Motor Vehicles which supplies information to DMV offices across the state. The services were up and running by midday.
But then Boise Police and Fire were summoned to the headquarters of ITD on State Street in Boise just before noon after officials reported "an unknown substance had been received by an office inside the building." Hazmat crews asked ITD employees to remain in the building and kept others from entering the building until safety could be assured.
"All steps are being taken at this time to ensure [the safety] of employees of ITD, pending identification of the substance," said a statement from Boise Police.
State Street traffic was not being impacted.
