The Lockport Industrial Area was created by the Calcasieu Parish Police Jury in 1966.
Since then, it has expanded four times - the last expansion was in 2014.
Thursday marks its fifth expansion.
Currently, eight other industrial facilities are located in the Lockport Industrial Area. This one comes with major economic impacts.
Axiall called for a feasibility study last November.
The 14-page study outlining the expansion was shared with jurors Thursday.
"The study authorized by the police jury in November of last year was requested by Axiall," said Wes Crain, director of planning and development.
Axiall and Lotte Chemical - a south Korean corporation - plan to turn some 600 acres of company-owned land into a $3 billion investment.
"The new Lockport Industrial Area that's being proposed is about a 600-acre site to the south of the 210 bypass loop," explained juror Les Farnum.
The site will hold an ethane cracker and mono-ethalyne glycol manufacturing plant. But before construction, it needed the police jury's approval to include their land in the Lockport Industrial Area.
"From the company's perspective, there are a number of benefits when locating within a formally recognized industrial area," said Crain.
Crain said a benefit is companies being eligible for rebates on sales tax paid on construction.
It raised this question from juror Dennis Scott:, "Do we have any idea how much that sales tax rebates going to be on that project?"
While Crain did not have the figures, it was determined Axiall would provide them in the future.
Crain said the designation also provides some assurances.
"Therefore the companies have some assurance against residential encroachment," he said.
The joint venture LACC, LLC got that approval.
"It's in full swing, going to be another great expansion in the Calcasieu area for job opportunities," explained Farnum.
Crain added, "2,000 construction jobs and 215 permanent jobs."
According to Axiall and Lotte Chemical, construction is set to begin this year. They're expected to be completed in 2019.
