Changes to post office hours of operation will likely impact most rural offices in Natrona County. Meantime Casper and its surrounding community offices should have no impact. That comes  from Postal Spokesman for the state of Wyoming David Rupert.

"Just about every rural office in the state will be effected in some way or another. Some may see their hours adjust by a couple hours a day. Some may not see any at all. Some may see personnel changes, because we're going to more of a part-time workforce."

Adjustments are expected to bring about $500 million in savings Rupert says. A relative drop in the bucket after a reported $3 billion in losses the first quarter of 2012.

He says adjustments to about 80 offices across the state are just one of many moves to bring the postal service to sustainability.

In Natrona County, offices in Midwest-Edgerton, Powder River, and Alcova could see those cutbacks roll out over the next two years.

Access to post office lobbies and boxes should remain along with retention of zip codes.
