What type of person can perform inspections of silt retaining dams?

The ability to perform inspections of silt retaining dams requires specific training and knowledge related to the structure and the regulations governing such inspections. A qualified person designated by the operator is someone who has the necessary training, experience, and authority to assess the integrity and safety of the dam. This designation ensures that inspections are conducted by individuals who understand the operational parameters and environmental implications of the structure, which is critical for maintaining safety and compliance.

This role typically involves understanding engineering principles, relevant regulations, and the specific conditions that may affect the dam's functionality. The operator designates this qualified individual to ensure that inspections align with safety standards and operational protocols. Hence, the emphasis on this designation is crucial for maintaining the safety of the dam and adherence to regulatory standards.

While other options may indicate individuals with various roles, they do not imply the specific training or authority required to conduct such inspections accurately and safely.
