Eastern States Consortium

Sarah Mildren Long Bridge - Portsmouth, NHWelcome to the Eastern States Consortium!

The New England states and New York, New Jersey, North Carolina, Pennsylvania, Delaware, Maryland, Virginia, and the District of Columbia have formed the Eastern States Consortium (ESC) to establish minimum requirements for the quality control procedures that the manufacturers of High Density Polyethylene Pipe must subscribe to in order to supply pipe to participating states.

It is the intent for the States to benefit through cooperative inspection and qualification processes and for the manufacturers to benefit through having one uniform set of quality control requirements to meet for all of the participating states.
