INSPECTION AND MAINTENANCE• Inspect drain inlet <strong>BMP</strong>s prior to forecast rain, daily during extended rainevents, after rain events, weekly during the rainy season, and at two-weekintervals during the non-rainy season.• Replace clogged, torn, or degraded materials.• Drive stakes securely into the ground.• Ensure stakes are in good condition (not bent, cracked, or splintered, andreasonably perpendicular to the ground). Replace damaged stakes as needed.• When the gravel in gravel filters becomes clogged with sediment, carefullyremove the filter from the inlet and either clean or replace it. Since cleaninggravel at a construction site may be difficult, consider using the sedimentladengravel as fill material and put fresh gravel around the inlet.• Inspect fiber rolls and gravel bags for holes, gashes, and snags, and replacebags as needed. Check fiber rolls and gravel bags for proper arrangement andplacement.• Periodically remove sediment that accumulates in the drain inlet protection.Remove sediment when sediment accumulation reaches one-third the heightof the filter. Incorporate sediment removed during maintenance intoearthwork on the site or dispose of it at an appropriate location.• Remove storm drain inlet protection once the drainage area is stabilized.Clean the area around and inside the inlet, as it must be free of sediment anddebris at the time of final inspection.• When removing geotextile fabric or a pre-made proprietary drain inletprotection device from underneath the grate, ensure that trapped sediment isnot spilled into the storm drain.Chapter 4: <strong>BMP</strong> ToolkitTRPA <strong>BMP</strong> Handbook4.5.2.2-Drain Inlet Protection 2012Page 4
