Sanofi-Pasteur plans to build a 19,000-square-foot addition to its distribution facility in Taylor.
Company representatives submitted plans to Taylor planning officials last month.
Sanofi-Pasteur spokeswoman Ellyn Schindler declined comment on the project or timeframe, saying discussion on their plans were premature.
The company hopes to break ground in the spring, Taylor borough officials said. The Taylor Planning Commission offered tentative approval of the company's plans Feb. 4.
The existing distribution center, opened in 2003, is 77,000 square feet and can fulfill one million orders annually. The Stauffer Industrial Park facility ships both vaccines and other medical supplies and equipment.
Ms. Schindler said the potential expansion would increase the facility's capacity and allow it to take on other distribution assignments in the Sanofi organization.
The planned expansion of the facility indicates it is successful and efficient, said Austin Burke, president of the Greater Scranton Chamber of Commerce.
"This is not a pick-and-pack operation," Mr. Burke said. "This is a serious operation that requires skill, controls and information technology."
He said the growing presence of Sanofi-Pasteur provides leverage to the Regional Bioscience Initiative to grow the life sciences sector in the local economy.
Sanofi-Pasteur is the world's largest vaccine maker. The Taylor facility supports both its vaccine manufacturing operation in Swiftwater and VaxServe in Scranton.
