Amendment 0002 EBS EXCEPTION FIG A pdf.pdf

This document is a technical clarification and revision notice for Figure 4, Detail A, pertaining to Erosion Control Blanket System (EBS) cell construction specifications. The revision establishes precise staple location requirements and dimensional tolerances at the top of EBS cells to eliminate ambiguity in manufacturing and installation.

The revised Detail A specification requires a top margin of 0.75 inches ± 0.25 inches (19 mm ± 6 mm) and a 3-inch ± 0.25-inch (76.2 mm ± 6 mm) horizontal dimension. The cell width is specified as 15 inches (381 mm), with a 3.5-inch ± 0.25-inch (90 mm ± 6 mm) fabric overlap on the left side. Detail B clarifies stapling requirements for geotextile application along the bottom row of wire mesh, with minimum staple quantities varying by EBS panel type: minimum 2 staples per panel for EBS types 2, 5, 9, and 11; minimum 3 staples per panel for EBS types 1, 3, 4, 8, and 12; and minimum 4 staples per panel for EBS types 7 and 10. The specification includes both imperial and metric measurements to ensure precise manufacturing compliance.
