A soil erosion and sedimentation control plan shall be submitted with any permit application for development or site work when the disturbed area of such development or activity is cumulatively more than 5,000 square feet or within 100 feet of any water body, watercourse and/or wetland.
This chapter shall not apply to the following:
A. 
Land disturbance activities over which the State of Connecticut has exclusive regulatory jurisdiction.
B. 
Construction activities essential to protect human life during a declared emergency.
A. 
A soil erosion and sediment control plan shall be developed using the guidelines and best management practices outlined in the Connecticut Guidelines for Soil Erosion and Sediment Control 2002 as amended and/or any other applicable soil erosion professional document. The soil erosion and sediment control plan shall develop a construction sequence and methods which minimize the potential for soil erosion and sedimentation during and after any proposed construction activities, including the mitigation of existing conditions. The Planning and Zoning Commission during its review of any project's soil erosion and sediment control plan may approve such plans that may be contrary to the prescribed guidelines if technically sound reasoning is presented by the applicant.
B. 
The soil erosion and sediment control plan needs to incorporate the following principles:

The professional engineer's certification may be waived by the Planning and Zoning Commission if it is deemed the proposed activities do not pose an erosion threat.
E. 
Applications associated with activities within 100 feet of any wetland and/or watercourse shall be referred to the Inland Wetlands Commission for its consideration, report or permit before the Planning and Zoning Commission shall render a decision on the soil erosion and sediment control plan.
F. 
The Planning and Zoning Commission may require the applicant of any approved plan to post a bond in an amount determined by the Commission to be equal to the cost of installing and maintaining the erosion control measures or the estimated costs of mitigating any impacts as the result of a failure, whichever is greater.
G. 
The Planning and Zoning Commission shall approve the proposed soil erosion and sediment control plan as presented, modify and approve the plan or reject the plan.
A. 
Inspections shall be made by the Commission or its designated agent during construction to ensure compliance with the approved plan and ensure the control measures are properly installed and maintained. The Commission may also require the applicant to verify, in writing, that the construction methods and erosion control measures have been performed and/or installed in accordance with the approved plan and are installed and maintained on a weekly basis and before and after each storm event.
B. 
During such inspection, if activities are deemed inconsistent with the approved plan, the Planning and Zoning Commission shall issue a notice of violation or cease and desist order which shall be maintained until such time the applicant prepares and is authorized to proceed with corrective actions.
C. 
The applicant may request a hearing before the Planning and Zoning Commission to demonstrate that his actions are in compliance with the approved plan. Such hearing shall be requested within 10 business days of issuance of the notice or order. The hearing shall be held within 10 business days of such request. A final decision from the Commission shall be rendered within 10 business days of the hearing.
