Ewing Street Business Park, Expected Completion 2015

The city’s infrastructure currently provides 6” and 4,” 34-psi natural gas pipeline with 1,000 Dth per day capacity. However, the city’s infrastructure has the capacity to provide additional natural gas supply to this site through a 12” diameter pipeline just north of the site, making the total capacity available 3,000 Dth per day. This extension can occur within a two month time period and would be completed at no cost to the end user.
