The State Ports Authority has scheduled a special meeting on Tuesday to discuss action needed for development of an Upstate cargo yard in Greer.

Agency officials have said the 40-acre project remains scheduled to open in September, despite an escalating legal dispute with a tenant that leases part of the site.

The board scheduled a special teleconference regarding the project for Tuesday at 11 a.m. The SPA broke ground March 1 on the inland port, where shipping containers will be transferred between trucks and Norfolk Southern rail cars running to and from Charleston. In March, the SPA board voted to seek to force Nordic Cold Storage to move by condemning and demolishing its building.

Lawyers for Nordic filed a lawsuit in Spartanburg County Circuit Court on April 11, challenging the condemnation plan.

The SPA board also recently approved increasing the state agency’s investment in the project by nearly 50 percent. The cost of the inland port is shared with Norfolk Southern.

The original estimate for the development was $33.6 million, with $26.1 million coming from SPA and a maximum of $7.5 million coming from Norfolk Southern. Updated estimates raised the price to as high as $47.4 million, with about $39 million coming from the SPA.

SPA staff said the extra $12.9 million includes the acquisition of more property to increase the size of the yard to about 40 acres.
