The Borough will notify the applicant in writing within 45 days whether the SWM site plan is approved or disapproved. If the SWM site plan involves a subdivision and land development plan, the notification period is 90 days or as waived by the applicant. If a longer notification period is provided by other statute, regulation, or ordinance, the applicant will be so notified by the Borough. If the Borough disapproves the SWM site plan, the Borough shall cite the reasons for disapproval in writing.

At its sole discretion and in accordance with this Subpart, when a SWM site plan is found to be deficient, the Borough may either disapprove the submission, require a resubmission, or accept the SWM site plan with conditions.
[Ord. No. 1358, 9/12/2022]
A modification to a submitted SWM site plan that involves a change in SWM BMPs or techniques, or that involves the relocation or redesign of SWM BMPs or that is necessary because soil or other conditions are not as stated on the SWM site plan as determined by the Borough shall require a resubmission of the modified SWM site plan in accordance with this Subpart.
[Ord. No. 1358, 9/12/2022]
A disapproved SWM site plan may be resubmitted, with the revisions addressing the Borough's concerns, to the Borough in accordance with this Subpart. The applicable review fee must accompany a resubmission of a disapproved SWM site plan.
[Ord. No. 1358, 9/12/2022]
The Borough's approval of an SWM site plan authorizes the regulated activities contained in the SWM site plan for a maximum term of validity of five years following the date of approval. The Borough may specify a term of validity shorter than five years in the approval for any specific SWM site plan. Terms of validity shall commence on the date the Borough signs the approval for an SWM site plan. If an approved SWM site plan is not completed according to this § 26-226 within the term of validity, then the Borough may consider the SWM site plan disapproved and may revoke any and all permits. SWM site plans that are considered disapproved by the Borough shall be resubmitted in accordance with § 26-225.
