In the past, developers needed only worry about controlling erosion during construction for projects disturbing 5 acres or more of land. That has all changed. The 5 acre threshold has been reduced to 1 acre. There are now requirements for both erosion control and proper hazardous material storage during construction. Site planning must include measures to avoid sensitive areas, decrease impervious surface area, and provide for on-site treatment of stormwater runoff using Best Management Practices (BMPs). Construction projects will need to apply for a local permit which will include a review of plan sheets and project sequencing.
So, generally speaking, those construction sites that involve the disturbing of one (1) acre or more of land (or any phased project that disturbs one (1) acre or more over a period of time) require Rule 5 Permits.
The following forms are provided for your convenience:
BOND RELEASE - APPLICATION FORM - The purpose of this form is to determine eligibility for bond release. It must be submitted along with Bond Release Self-Inspection Form and the Certificate of Completion.
BOND RELEASE - CERTIFICATE OF COMPLETION - This form indicates that construction has been completed in compliance with storm water standards. It must be submitted as part of the bond release application process.
Also, the Indiana Department of Natural Resources, Division of Soil Conservation, has updated the
Indiana Storm Water Quality Manual formerly known as the Indiana Handbook for Erosion Control. In addition to erosion and sediment control, the updated handbook includes information, specifications, and measures that address minimization of post construction pollutants.
