The Board shall disapprove, approve or conditionally approve the final site plan within 45 days after the date on which the application is deemed to be complete, or within such additional time as is agreeable to the applicant. The Board shall not approve the site plan if the County Planning Board report, when required, is unfavorable or prior to the expiration of the 30 day period within which the County Planning Board may submit a report on the site plan; provided, however, that if a report from the County Planning Board has not been received, the Board may approve the site plan conditional upon the receipt of notice of approval by the County Planning Board or the expiration of the 30 day period. If the Board disapproves or requires a revision of the site plan for any reason, it shall fix the amount of the fee, not to exceed the amount required for the original filing, to be filed with the Borough Clerk with the revised site plan, and its decision stating the reasons for such reapproval or required revisions shall be sent to the applicant.
