How many types of standard inlet protection are there?

The correct choice indicates that there are two types of standard inlet protection measures available. Inlet protection is crucial in managing sediment and preventing debris from entering storm drain systems during construction activities. The two types typically include options like silt fences or gravel bags placed around the drains to filter out sediment and prevent it from clogging the system.

Understanding the two types allows for flexibility in implementation based on site-specific conditions, such as the volume of runoff and the type of soil present. Each type of protection has its own application methods and materials that cater to different scenarios, ensuring effective erosion and sediment control.

Recognizing the distinction between the types is essential for compliance with Maryland's Erosion and Sediment Control regulations, which emphasize effective methods for minimizing sedimentation during construction projects. Knowing that there are two options encourages practitioners to select appropriate measures that fit the specific site requirements, thereby enhancing the control of sediment movement to protect water quality during construction activities.
