The court interprets Exemption 11 of the Highlands Act, N.J.S.A. 13:20-28(a)(11), which exempts entirely from all provisions of the Act and "any rules or regulations" adopted by the DEP pursuant to it:
the routine maintenance and operations, rehabilitation, preservation, reconstruction, repair, or upgrade of public utility lines, rights of way, or systems, by a public utility, provided that the activity is consistent with the goals and purposes of this act,
to exempt only "routine" upgrades to a utility's lines, rights of way or systems in the Preservation Area, rejecting the DEP's interpretation that "routine" modifies only "maintenance and operations" and does not modify "upgrade."
Applying its interpretation, the court vacates the Highlands Applicability Determination issued to the Tennessee Gas Pipeline Company exempting its proposed compressor station in the Preservation Area from permitting review and remands the matter to the DEP for consideration of whether Tennessee's new compressor station can qualify as a "routine upgrade" to its pipeline system, thus bringing it within Exemption 11.
