The Georgia Soil and Water Conservation Commission has published a document for approving “alternative BMP’s” . Below you will find an excerpt from the GSWCC document and a link to the full PDF. Also, you will find the resources needed for approving some of the commonly used Polymer Enhanced BMP’s.
GSWCC Guidance Document for Alternative BMP’s
Permit Erosion and Sedimentation Controls:
Use of alternative BMPs whose performance has been documented to be equivalent or superior to conventional BMPs as certified by a Design Professional may be allowed (unless disapproved by EPD or the Georgia Soil and Water Conservation Commission).
Required Documentation for Alternative BMP:
1. One page summary detailing why the alternative BMP is equivalent or superior to the conventional BMPs found in the “Manual for Erosion and Sedimentation Control in Georgia” (Manual). 2. Documented side by side testing (alternative BMP vs. conventional BMP) using the appropriate design requirements and specifications contained in the Manual. 3. Proof that the alternative BMP was previously installed and worked under conditions comparable to the environmental conditions of the proposed site. This can be documented with photographs. 4. All specifications including the design requirements and the procedures for proper installation and maintenance.
All forms of documentation must be signed and certified by the Design Professional who is preparing the ES&PC Plan and must includes the Design Professional’s seal and GSWCC Design Professional certification. Links and Resources for approval
