Editor's Note: See 53 P.S. § 10512.1.
A. 
SWM site plans not submitted as a component of a subdivision and/or land development plan. Revisions to a previously approved SWM site plan to incorporate a change in SWM BMPs or techniques, or the relocation or redesign of SWM BMPs, or different information about soil or other conditions from what was stated in the SWM site plan, shall be submitted by the applicant to the Township. The Township in its sole discretion may require a resubmission and full review of the revised SWM site plan in accordance with this Part 2, including applicable review fees. For NPDES permitted sites, any revised SWM site plan shall be resubmitted to the Adams County Conservation District for its review. In the case of an SWM site plan which contains minor deficiencies (such as a missing label, omission of a required note or minor construction detail), the Township may, in its sole discretion, accept a resubmission of such SWM site plan without the requirement of a full review fee, or a lesser fee.
B. 
SWM site plans submitted as a component of a subdivision and/or land development plan. A revision of an SWM site plan approved as a component of a subdivision and/or land development plan shall be treated as a revision of the subdivision and/or land development plan and shall be subject to the review process established in Chapter 275, Subdivision and Land Development.
A. 
SWM site plans not submitted as a component of a subdivision and/or land development plan. A previously disapproved or deemed denied SWM site plan may be resubmitted with the revisions addressing all of the defects of the original submission. The resubmitted SWM site plan shall be reviewed and acted upon in accordance with § 263-66B(1) of this Part 2. The applicable review fee must accompany the submission of a revised SWM site plan, unless such fee is waived by the Township.
B. 
SWM site plans submitted as a component of a subdivision and/or land development plan. The resubmission of the SWM site plan originally submitted as a component of a subdivision and/or land development plan shall be treated as resubmission of said subdivision and/or land development plan and shall be subject to the review process established in Chapter 275, Subdivision and Land Development.
A. 
SWM site plans not submitted as a component of a subdivision and/or land development plan. The Township's approval of an SWM site plan, when such plan is not submitted as a component of a subdivision and/or land development plan, authorizes the regulated activities contained in the SWM site plan for a maximum term of five years following the date of approval. The Township may specify a term shorter than five years in the decision notification for any specific SWM site plan if the nature of the proposed SWM facilities requires more frequent maintenance (more than annual) and/or short-term replacement of certain components. Terms of authority for the regulated activities shall commence on the date the Township votes to approve the SWM site plan. If an approved SWM site plan is not completed according to § 263-70 within the authorized term, and if a request to extend the permit has not been submitted to the Township by the applicant, the authority terminates and the Township may revoke any and all permits applicable to the project. SWM site plans for projects with expired permits may be resubmitted in accordance with § 263-68 of this Part 2.
B. 
SWM site plans submitted as a component of a subdivision and/or land development plan. The term of authority for regulated activities for an SWM site plan as a component of a subdivision and/or land development plan shall be in accord with the law governing such plans.
A. 
Prior to commencing construction of stormwater management facilities, the applicant or its agent shall contact the Township's Engineer to determine at which stages of construction the facilities shall be inspected. No facilities or portion thereof shall be buried or otherwise permanently covered unless and until the inspection of that stage, as determined by the Township Engineer, has been performed and that stage of construction has been approved.
B. 
The stormwater management facilities constructed in accordance with an SWM site plan not submitted as a component of a subdivision and/or land development plan shall be subject to the following process upon the completion of construction of said facilities.
(1) 
The property owner or developer shall contact the Township within seven days of the completion of the construction process to schedule a final inspection. The final inspection shall be conducted by the Township Engineer or such other person designated by the Township.
(2) 
The Township may inspect the completed improvements to confirm consistency with the approved SWM site plan. Following the inspection, if any, the Township may take one of the following two actions:
(a) 
Issue a completion certificate. A completion certificate may be issued when the Township determines that the stormwater management facilities have been constructed in conformance with the approved SWM site plan.
(b) 
Issue correspondence regarding discrepancies. If the Township determines that the stormwater management facilities have not been constructed in accordance with the approved SWM site plan, it shall issue correspondence addressed to the property owner or developer summarizing the discrepancies from the approved SWM site plan. Such correspondence does not by itself constitute an extension of any applicable SWM permit.
(3) 
Upon receipt of correspondence summarizing discrepancies in the constructed stormwater facilities, the property owner or developer shall apply for permit extensions when necessary, and take one of the following two actions.
(a) 
Reconstruct the required stormwater management facilities in a manner that complies with the approved SWM site plan. Prior to commencement of the reconstruction work, the property owner or developer shall contact the municipality for an inspection schedule in accordance with the process established in § 263-70A.
(b) 
Submit a revised SWM site plan in accordance with the process established in § 263-67A. The revised SWM site plan shall be consistent with the improvements as constructed. Upon receipt, the Township may review the revised SWM site plan in accordance with the review and approval process of § 263-66. If the revised SWM site plan is approved, the Township shall issue the completion certificate. If the revised SWM site plan fails to demonstrate that the constructed stormwater management facilities can comply with the requirements of this Part 2, the Township may then require the property owner or developer to reconstruct the required stormwater facilities in accordance with the originally approved SWM site plan. If the revised SWM site plan is approved, the Township shall then issue the completion certificate.
(4) 
Within 15 days of the completion certificate, the property owner or developer shall submit to the Township an as-built plan depicting the stormwater management facilities as constructed. If requested by the applicant, the Township may grant an extension of the deadline to submit as-built plans.
C. 
The stormwater management facilities constructed in accordance with an SWM site plan submitted as a component of a subdivision and/or land development plan shall be subject to the completion of improvements requirements of Chapter 275, Subdivision and Land Development, and Sections 509 through 511 of the Pennsylvania Municipalities Planning Code, as amended.[1]
