Which of the following is a key responsibility of the environmental agencies as specified in NEPA?

The key responsibility of environmental agencies as specified in the National Environmental Policy Act (NEPA) primarily includes providing technical assistance for pollution control. NEPA focuses on ensuring that federal agencies assess the environmental impacts of their proposed actions and decisions, which involves technical expertise in pollution control measures. This responsibility underscores the importance of integrating environmental considerations into federal planning and decision-making.

Technical assistance for pollution control is essential, as it involves helping industries and other entities comply with environmental regulations, identifying best practices, and supporting the implementation of environmental protection measures. By emphasizing technical support, NEPA aims to foster a collaborative approach in addressing environmental issues rather than solely relying on enforcement or regulation.

Other options, while they may involve aspects of environmental work, do not specifically align with the core responsibilities framed by NEPA. Monitoring climate change effects is crucial but falls more under research and policy rather than the direct responsibilities attributed to environmental agencies under NEPA. Enforcing international environmental laws and granting permits for industrial expansion typically involve different regulatory frameworks that extend beyond the primary scope of NEPA's focus on environmental assessments and informed decision-making.
