PERMIT REQUIREMENTS AND PROCEDURES
§ 55.080 PERMIT PROCEDURES.
   (A)   This subchapter applies to all development, or re-development of land, that results in land disturbance of one acre or more. Individual lots with land disturbance less than one acre shall refer to §§ 55.055 et seq. and §§ 55.070 et seq. for plan review requirements and procedures. Figure 1 is a flowchart summarizing the plan review/permit approval process and can be found at the end of this subchapter.
   (B)   All projects located within the corporate boundaries of the Town of Sellersburg lie within the town's MS4 area boundary by default. The project site owner shall submit an application for a stormwater management permit to the town. The application will include construction plan sheets, a stormwater drainage technical report, a SWPPP, and any other necessary support information. Specific information to be included in the application can be found in § 55.081 below. Four copies of each application must be submitted to the town. The town may, at its discretion, require one or more copies be submitted to the Clark County Surveyor, or other entity deemed appropriate by the town. Additionally, a digital copy of the construction plans is required in a format accepted by the town.
   (C)   After the town’s receipt of the application, the applicant will be notified as to whether their application was complete or insufficient. The applicant will be asked for additional information if the application is insufficient. If the application is complete, it will be reviewed in detail by the town and/or its plan review consultant(s). Once the review has been completed, the Town Planning and Zoning Director or their designee will either approve the project, request modifications, or deny the project.
   (D)   The project site owner must notify the town and IDEM 48 hours before beginning construction. Notification shall be in the form of an updated IDEM NOI form. Once a permit has been issued and the updated NOI submitted to the town and IDEM 48 hours before the beginning of construction, construction may commence. Once construction starts, the project owner shall monitor construction activities and inspect all stormwater pollution prevention measures in compliance with this chapter and the terms and conditions of the approved permit. Upon completion of construction activities, as-built plans must be submitted to the town. A notice of termination (NOT) shall be sent to the town once the construction site has been stabilized and all temporary erosion and sediment control measures have been removed. The town, or its representative, shall inspect the construction site to verify that the requirements for an NOT have been met. Once the applicant receives a “verified" copy of the NOT, they must forward a copy to IDEM. Permits issued under this scenario will expire five years from the date of issuance. If construction is not completed within five years, the NOI must be resubmitted at least 90 days prior to expiration.
