NATCHEZ — Approximately 320 permanent jobs, 400 construction jobs and a $350 million investment may not be all fuel company KiOR brings to Natchez.

In addition to the Natchez facility the company has previously announced, KiOR may one day expand in Adams County, operating not just a crude oil production facility but an upgrading facility to refine the product, CEO Fred Cannon said Thursday.

The company’s chief executive officer and chief financial officer spent the latter part of the week in Natchez, touring the production plant’s future site, making local connections and meeting with the members of Natchez Inc. and Natchez Now.

Plans for a second Natchez facility are only a long-term option right now, but Cannon also mapped out company plans for the near future, too.

Cannon said the initial $350 million investment could result in 400 construction jobs during the projected 18 months it would take to build the alternative fuels facility at the former Belwood Country Club site.

That construction is slated to begin in the second quarter of 2013 — after March 1 — and continue until the third quarter of 2014.

The first wave of hiring would begin with recruiting in the fourth quarter of 2013, followed by several months of training.

Full-time employment at the plant would begin in the third quarter of 2014, just before the plant is scheduled to begin production.

“This will be our flagship plant,” Cannon said. “We’ll have quite some staff here.”

The 320-job estimate includes indirect jobs in the logging industry. Cannon defined “direct and indirect jobs” to a group of community leaders Friday as people who work for the plant and those who provide the feedstock to the plant.

“These (plant) jobs are the same skill level as the board operators at the International Paper plant,” Cannon said.
