Impervious surface. Any regulated activity that has less than 5,000 square feet of impervious surface and/or meets the exemptions in this section is exempt from the plan submittal provisions of this Part 1. These criteria shall apply to the total development even if development is to take place in phases. The date of the original Brodhead or McMichaels Municipal Ordinance adoption shall be the starting point from which to consider tracts as "parent tracts" in which future subdivisions and respective impervious area computations shall be cumulatively considered. The date of the original Brodhead Creek Watershed Plan Municipal Ordinance (No. 368) adoption was January 18, 1993. The date of the original McMichaels Creek Watershed Plan Municipal Ordinance (No. 352) adoption was January 26, 1989. Impervious areas existing on the parent tract prior to adoption of this Part 1 shall not be considered in cumulative impervious area calculations for exemption purposes.
Utility uses, including stormwater, water, sewer, electric, telecommunication and telephone uses, but excluding any building or other impervious surfaces relating to same.
Additional exemption criteria include:
Exemption responsibilities. Any exemption listed in § 124-18 shall not relieve the applicant from implementing such measures as are necessary to protect the public health, safety, and property. An exemption shall not relieve the applicant from providing adequate stormwater management for regulated activities to meet the purpose of this Part 1; however, drainage plans will not have to be submitted to the municipality. The Township reserves the right to require stormwater management design and implementation for any regulated activity that is less than 5,000 square feet or otherwise exempt under § 124-18A.
Any exemption listed in § 124-18 shall not relieve the applicant from meeting the special requirements for watersheds draining to exceptional-value (EV) waters and source water protection areas (SWPA): requirements for nonstructural project design sequencing, water quality and streambank erosion, groundwater recharge and any other requirement of this Part 1.

The responsibility for providing stormwater control facilities will be on the lot owner, and an occupancy permit shall not be issued until facilities are installed on the lot. Several options in which the lot owner can utilize storage are specified in Appendix H. Each option will vary depending upon the existing physical situations.
General guidelines which must be followed are:
Lots in which the soil probe performed for the sewage disposal system shows mottling within 24 inches of the soil surface may not utilize subsurface storage. All storage must be supplied using surface control means. Lots showing mottling greater than 24 inches from the soil surface may use subsurface storage facilities.
Lots in which the percolation rate is greater than 120 minutes per inch must use surface stormwater control means.
All fees shall be reimbursed through the building permit process. The inspection of the stormwater control facilities shall be performed by the SEO at the same time the septic systems or lateral hookup inspections are made or by any duly authorized and appointed officer/agency of the municipality.
Exemption. If an undeveloped lot adjoins a natural or man-made lake, the property owner is exempt from individual on-lot stormwater detention requirements, provided that all stormwater runoff from the new impervious surface (after development) contains appropriate water quality control measures and is directed and properly channeled into the lake in a manner and form acceptable to the municipality.
The municipality shall require receipt of a complete drainage plan, as specified in this Part 1. For any regulated activities that require an NPDES permit for stormwater discharges from construction activities or a PaDEP joint permit application or a PennDOT highway occupancy permit, or any other permit under applicable state or federal regulations, or regulated under Chapter 105, Dam Safety and Waterway Management, or Chapter 106, Floodplain Management, of PaDEP's rules and regulations, the proof of application for said permit(s) and/or approvals shall be part of the drainage plan. The plan shall be coordinated with the state and federal permit process and the municipal SALDO review process.
For those regulated activities which require SALDO approval, the drainage plan and ERSAM shall be submitted by the applicant as part of the preliminary plan submission.
For those regulated activities that do not require SALDO approval, the drainage plan and ERSAM shall be submitted to the municipality by the applicant as part of the permit application and in all situations prior to any construction or land disturbance.
Six copies of the drainage plan shall be submitted and distributed as follows:
Two copies to the municipality accompanied by the requisite municipal review fee, as specified in this Part 1, and set forth in the professional services agreement required by this Part 1.
Two copies to the Conservation District.
One copy to the Municipal Engineer.
One copy to the County Planning Commission.
Any submissions found incomplete shall not be accepted for review and shall be returned to the applicant with a notification in writing of the specific manner in which the submission is incomplete.
Notwithstanding any other provision of this article, any plan required to be submitted by this article shall also include a copy on computer-readable media in either auto-cad R-14, auto-cad 2000, TIFF image format or ESRI Arc Infro\\arcview, with all required media containing Pennsylvania State Plane N, NAD 83 Coordinates, or such other electronic, digital or computer-readable media or format as designated from time to time by resolution duly enacted by the Board of Supervisors.
The municipality's engineer shall review the drainage plan for consistency with this Part 1 and the adopted Brodhead and McMichaels Creek Watershed Act 167 stormwater management plan.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
The refusal of the governing body to reissue an expired drainage plan shall contain the reasons for such refusal.
Changes in project site conditions and requirements for the drainage plan may occur over a period of time.
If the requirements for the drainage plan have changed as determined by the governing body, reapplication, review and permit issuance requirements must be performed pursuant to this Part 1.
The developer shall be responsible for completing an as-built survey of all stormwater management facilities included in the approved drainage plan. The as-built survey and an explanation of any discrepancies with the design plans shall be submitted to the municipality for final approval.
A modification to a drainage plan under review by the municipality for a development site that involves a change in stormwater management facilities or techniques, that involves the relocation or redesign of stormwater management facilities, or that is necessary because soil or other conditions are not as stated on the drainage plan as determined by the municipality's engineer shall require a resubmission of the modified drainage plan consistent with this Part 1 and be subject to review as specified in this Part 1.
A modification to an already approved or disapproved drainage plan shall be submitted to the municipality, accompanied by the applicable municipal review and inspection fee. A modification to a drainage plan for which a formal action has not been taken by the municipality shall be submitted to the municipality, accompanied by the applicable municipal review and inspection fee.
A disapproved drainage plan may be resubmitted, with the revisions addressing the Municipal Engineer's concerns documented in writing and addressed to the Municipal Secretary in accordance with this Part 1 and distributed accordingly and be subject to review as specified in this Part 1. The applicable municipal review and inspection fee must accompany a resubmission of a disapproved drainage plan.
