December 18, 1978 Interpretation of "Constructed" as it Applies to Activities Undertaken Prior to Issuance of a PSD Permit 14.4

A structure which is to house independent facilities, some of which are subject to PSD and some of which are not, maybe constructed before a PSD permit is issued only if the building is a necessary part of the PSD-exempt project and if it is in no way modified to specifically accommodate the PSD-affected facilities. The MATEP project involves the construction of steam boilers, exempt from PSD requirements, and diesel engines, subject to the PSD requirements. The boilers and engines are to be housed in the same building. MATEP may begin construction on the building before the PSD permit is issued as long as the drains, piping, footings for the diesel and any other installation necessary to accommodate the diesels are not installed until the permit is issued.
