GROTON — Konover Development Corp., the company that wants to build a Wal-Mart Super Center on Route 184 in the watershed of the Groton Utilities reservoir system, has agreed to an extension of the deadline for a Planning Commission decision on its new application for the facility.

Diane Whitney, attorney for Konover, has sent a letter to the commission granting a new date for final decision of June 21, 2008. Previously, the deadline had been April 17, 2008.

At the same time Konover is submitting a new application to the Planning Commission for the super center, it is appealing an early 2007 decision by the commission to deny its first application. The Superior Court at New London is due to hear arguments in the Planning Commission appeal on April 8, 2008.

The Inland Wetlands Agency approved the project in 2006, but will hear on April 9, 2008, Konover’s application to modify certain aspects of the approved plan.

Under Connecticut law, the Planning Commission must act upon a developer’s applications within 65 days of receiving it unless the developer agrees to an extension.
