TABLE OF CONTENTS This prerequisite is intended to control erosion and pollutant transport off-site during and after construction to minimize their impact on the surrounding areas and on water and air quality. LEED NC-2.2 lists the Intent, Requirements, and Potential Technologies and Strategies for this credit as follows:
Intent
Reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation.
Requirements
Create and implement an Erosion and Sedimentation Control (ESC) Plan for all construction activities associated with the project. The ESC Plan shall conform to the erosion and sedimentation requirements of the 2003 EPA Construction General Permit OR local erosion and sedimentation control standards and codes, whichever is more stringent. The Plan shall describe the measures implemented to accomplish the following objectives:
Prevent loss of soil during construction by stormwater runoff and/or wind erosion, including protecting topsoil by stockpiling for reuse.
Prevent sedimentation of storm sewer or receiving streams.
Prevent polluting the air with dust and particulate matter.
The Construction General Permit (CGP) outlines the provisions necessary to comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) program. While the CGP only applies to construction sites greater than 1 acre, the requirements are applied to all projects for the purposes of this prerequisite. Information on the EPA CGP is available at http://cfpub.epa.gov/npdes/stormwater/cgp.cfm.
Potential Technologies and Strategies
Create an Erosion and Sedimentation Control Plan during the design phase of the project.
