(A) This section applies to all development or re-development of land within unincorporated Boone County that are subject to § 153.002. Individual lots with land disturbance less than one acre that are developed within a larger permitted project site should refer to §§ 153.065 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 chapter.
(B) The project site owner shall submit an application for a stormwater management permit to the Boone County Surveyor's office. The application will include a Draft Notice of Intent letter (NOI) that would also act as permit application form, construction plan sheets, stormwater drainage technical report, a stormwater pollution prevention plan for construction sites (if the total disturbance is one acre or more), post-construction pollution prevention plan (if the total disturbance is one acre or more), and any other necessary support information. Specific information to be included in the application can be found in § 153.097 and in the Boone County Stormwater Technical Standards Manual. Adequate number of copies of each application material, as noted in the "Stormwater Permit Application Check-In Checklist" contained in the Boone County Stormwater Technical Standards Manual, must be submitted to the Boone County Surveyor's office. Additionally, a digital copy of the construction plans is required in a format accepted by the Boone County Surveyor.
(C) After the Boone County Surveyor's office 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. The information provided will be reviewed in detail by the Boone County Surveyor and/or its plan review consultant(s). Once all comments have been received and review completed, the Boone County Surveyor will either approve the project or request modifications.
(D) Once a permit has been issued, the project site owner must file a Notice of Intent a minimum of 48 hours prior to the commencement of construction activities. Notification shall be in the form of an updated NOI form. The submittal of the NOI must be provided to the Boone County Surveyor's office and, if the total disturbance is one acre or more, to IDEM as well. The IDEM submittal must include a proof of publication, verification that the jurisdictional entity approved the plan, and a $100 fee. For Boone County Surveyor's office, copies of the final, approved construction plans, stormwater drainage technical report, stormwater pollution prevention plan for construction sites (if the total disturbance is one acre or more), and post-construction stormwater pollution prevention plan shall also accompany the above-noted written notification and proof of publication. The number of required copies varies from case to case and additional copies may be requested by the Boone County Surveyor's office. A pre-construction meeting is required to be held with the participation of the Boone County Surveyor's office and other entities involved prior to any grading activity to ensure that appropriate perimeter control measures have been implemented on the site and the location of any existing tiles has been properly marked.
(E) Once construction starts, the project owner shall monitor construction activities and inspect all stormwater pollution prevention measures to verify 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 Boone County Surveyor's office. A Notice of Termination (NOT) shall be sent to the Boone County Surveyor's office once the construction site has been stabilized and all temporary erosion and sediment control measures have been removed. The Boone County Surveyor, or a representative, shall inspect the construction site to verify 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 if the total disturbance is one acre or more. 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.
