In his new position, Mr Radtke will be responsible for one of the largest natural gas processing operations in the US, consisting of more than 25 facilities that have net processing capacity of approximately nine billion cubic feet per day.

Mr Cardillo will oversee nearly 700 miles of petrochemical pipelines in addition to propylene fractionation, butane isomerization and octane additive production operations, including those at the partnership’s Mont Belvieu facility in Texas, which is claimed to be the world’s largest natural gas liquids fractionation complex.

Since joining Enterprise in 2002, Mr Radtke has been in charge of the partnership’s petrochemicals business group and has served as a COO, and a director of the general partner of Duncan Energy Partners (DEP).
