In the support letters of the CSX STB filing: "The commercial and residential propane distributors in New England are Sea-3's customers and look to Sea-3 for reliable and economic supply of propane in the region.
Blackline is expecting the CSXT Sales and Marketing team to follow through on its intentions to
explore and implement new supply chain solutions and market opportunities for expanded rail
movements of propane into Sea-3 which would support Blackline's ability to meet those
customer expectations. Black:line needs lower rail transportation unit costs, more frequent rail
service and expanded railcar blocks per delivery for better overall productivity which will lead to
improved overall performance and economics for the propane consumers in New England. "
