[Ord. 712, 8/8/2012, § 404]
1. 
SWM plans shall be submitted to the municipality for review by the Municipal Engineer for consistency with this chapter and the respective Act 167 Stormwater Management Plan. Any plan found incomplete may not be accepted for review and may be returned to the applicant. The Municipal Engineer will review the SWM site plan for any subdivision or land development against the municipal SALDO provisions not otherwise superseded by this chapter.
2. 
The applicant shall respond to the Conservation District comments on the SWM site plan prior to being considered for final approval by the municipality.
3. 
For activities regulated by this chapter (§ 23-105), the Municipal Engineer will notify the applicant and the municipality in writing, with a copy to the Building Permit Officer, within 30 calendar days, whether the SWM site plan is consistent with the storm water management plan.
A. 
If the Municipal Engineer determines that the SWM site plan is consistent with this chapter, the Municipal Engineer will forward a letter of consistency to the municipality, who will then forward a copy to the applicant.
B. 
If the Municipal Engineer determines that the SWM site plan is inconsistent or noncompliant with this chapter, the Municipal Engineer will forward a letter to the municipality, with a copy to the applicant citing the reason(s) and specific sections for the inconsistency or noncompliance. Inconsistency or noncompliance may be due to inadequate information to make a reasonable judgment as to compliance with the stormwater management plan. Any SWM site plans that are inconsistent or noncompliant may be revised by the applicant and resubmitted when consistent with this chapter.
4. 
For regulated activities under this chapter that require an NPDES Permit Application, the applicant shall forward a copy of the Municipal Engineer's letter stating that the SWM site plan is consistent with this chapter to the Conservation District. PADEP and the Conservation District may consider the Municipal Engineer's review comments in determining whether to issue a permit.
5. 
The municipality will not grant preliminary or final approval to any subdivision or land development for regulated activities specified in this chapter if the SWM site plan has been found by the Municipal Engineer to be inconsistent with this chapter. All required permits from PADEP must be obtained prior to approval of any subdivision or land development.
6. 
No building permits for any regulated activity specified in this chapter will be approved by the municipality if the SWM site plan has been found to be inconsistent with this chapter, as determined by the Borough Engineer and Conservation District, or without considering the comments of the Borough Engineer and Conservation District. All required permits from PADEP must be obtained prior to issuance of a building permit.
7. 
The applicant shall be responsible for completing record drawings of all stormwater management facilities included in the approved SWM site plan. The record drawings and an explanation of any discrepancies with the design plans shall be submitted to the Municipal Engineer for final approval. In no case will the municipality approve the record drawings until the municipality receives a copy of an approved declaration of adequacy and/or highway occupancy permit from the PennDOT District office, NPDES permit, and any other applicable permits or approvals from PADEP or the Conservation District. The above permits and approvals must be based on the record drawings.
8. 
The municipality's approval of a SWM site plan shall be valid for a period not to exceed five years commencing on the date that the municipality signs the approved SWM site plan. If stormwater management facilities included in the approved SWM site plan have not been constructed, or if constructed, record drawings of these facilities have not been approved within this five-year time period, then the municipality may consider the SWM site plan inconsistent or noncompliant and may revoke any and all permits. SWM site plans that are determined to be inconsistent or noncompliant by the municipality shall be resubmitted in accordance with § 23-406 of this chapter.
[Ord. 712, 8/8/2012, § 405]
1. 
A revision to a submitted SWM site plan under review by the municipality for a development site that involves the following shall require a resubmission to the municipality of a revised SWM site plan consistent with § 23-403 of this chapter and be subject to review as specified in § 23-404 of this chapter:
A. 
Change in stormwater management facilities or techniques.
B.
