The Township Committee, by resolution, shall either accept the improvements determined to be complete and satisfactory by the Township Engineer, or reject any or all of these improvements upon the establishment in the resolution of cause for rejection, and shall approve and authorize the amount of reduction or release to be made in the performance guarantee relating to the improvements accepted, in accordance with the itemized cost estimate prepared by the Township Engineer and appended to the performance guarantee pursuant to this chapter. This resolution shall be adopted not later than 45 days after receipt of the list and report prepared by the Township Engineer. Upon adoption of the resolution by the Township Committee, the obligor shall be released from all liability pursuant to its performance guarantee, with respect to those accepted improvements, except for that portion sufficient to secure completion or correction of the improvements not yet accepted, provided that 30% of the amount of the performance guarantee posted may be retained to ensure completion and acceptability of all improvements. If any portion of the required improvements is rejected, the Township shall require the obligor to complete or correct such improvements, and, upon completion or correction, the same procedure of notification, as set forth in this section, shall be followed.
