B. 
The municipality's engineer shall review the drainage plan for any subdivision or land development against the municipality's Subdivision and Land Development Ordinance provisions not superseded by this Part 1.[1]
[1]
Editor's Note: See Ch. 135, Subdivision and Land Development.
C. 
The E & S Plan shall be reviewed by the County Conservation District and found adequate to meet the requirements of PaDEP's Chapter 102 regulations prior to the commencement of any earth disturbance activities. The Conservation District shall also review the consumptive use tracking report when required by this Part 1. The Conservation District will track consumptive use. The Conservation District will notify the municipality when the threshold for consumptive use within a watershed or management area has been met, because subsequent drainage plan approvals will affect base flow, water quality and aquatic habitats.
D. 
For regulated activities such as land development, subdivisions and/or planned residential developments as specified in this Part 1, the municipality's engineer shall notify the Board of Supervisors in writing whether the drainage plan is consistent with the stormwater management plan prior to the approval of a final plan.
(1) 
Should the drainage plan be determined to be consistent with the stormwater management plan, the municipality's engineer will forward a letter of consistency to the Municipal Secretary, who will then notify the developer.
(2) 
Should the drainage plan be determined to be inconsistent or noncompliant with the stormwater management plan, the municipality's engineer shall forward a letter to the Municipal Secretary with a copy to the applicant citing the reason(s) and specific ordinance 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 drainage plans that are inconsistent or noncompliant may be revised by the applicant and resubmitted consistent with this Part 1. The Municipal Secretary shall then notify the developer of the municipality's engineer's findings. Any disapproved drainage plans may be revised by the developer and resubmitted consistent with this Part 1.
E. 
For regulated activities specified in this Part 1 which require a building permit and drainage plan submission, the municipality's engineer shall notify the municipality in writing whether the drainage plan is consistent with the stormwater management plan and forward a copy of the approval/disapproval letter to the applicant. Any disapproved drainage plan may be revised by the applicant and resubmitted consistent with this Part 1.
F. 
For regulated activities specified in this Part 1 that require an NPDES permit application, the applicant shall forward a copy of the municipality's engineer's letter stating that the drainage plan is consistent with the stormwater management plan to the Conservation District. PaDEP and the Conservation District may consider the municipality's engineer's review comments in determining whether to issue a permit.
G. 
The municipality shall not grant final approval of any land development, subdivisions and/or planned residential developments for regulated activities specified in this Part 1 if the drainage plan has been found to be inconsistent with the stormwater management plan, as determined by the municipality's engineer. A copy of all required permits/approvals from the PaDEP and the Conservation District must be provided to the municipality prior to plan recordation of any land development, subdivisions and/or planned residential developments.
H. 
No municipal permits shall be issued for any regulated activity specified in this Part 1 if the drainage plan has been found to be inconsistent with the stormwater management plan, as determined by the municipality's engineer, or without considering the comments of the municipality's engineer. All required permits from PaDEP must be obtained prior to issuance of a building permit.
I. 
The applicant shall be responsible for completing record drawings of all stormwater management facilities included in the approved drainage plan. The record drawings and an explanation of any discrepancies with the design plans shall be submitted with a certification from a professional engineer to the municipality's engineer for final approval. In no case shall the municipality accept 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, consumptive use tracking report as required by this Part 1, and any applicable permits or approvals from PaDEP or the Conservation District.
J. 
The municipality's approval of a drainage plan shall be valid for a period not to exceed five years, commencing on the date that the municipality signs the approved drainage plan. If stormwater management facilities included in the approved drainage plan have not been constructed, or, if constructed, and record drawings of these facilities have not been approved within this five-year time period, then the municipality may consider the drainage plan disapproved and may revoke any and all permits. Drainage plans that are considered disapproved by the municipality shall be resubmitted in accordance with this Part 1.
(1) 
A renewal of the expired drainage plan may be issued by the municipality following a resubmittal of the drainage plan. Additional fees must be paid for the resubmittal of an expired drainage plan.
(2)
