What is the primary agency for environmental regulation in Guam?

The Guam Environmental Protection Agency is the primary agency responsible for environmental regulation in Guam. This agency is tasked with enforcing laws related to air, water, and land quality, ensuring the protection of the environment and public health in the region. It oversees various environmental programs and initiatives, working to preserve natural resources and manage waste properly. The agency plays a crucial role in permitting, compliance monitoring, and implementing environmental policies that align with both local and federal regulations.

Other agencies listed may have specific roles related to environmental matters, but none have the comprehensive mandate that the Guam Environmental Protection Agency possesses. For instance, the Department of Natural Resources may deal with wildlife and fisheries, while the Department of Health and Social Services focuses more on public health issues. The Guam Resource Recovery Authority is concerned with waste management but does not cover the broader spectrum of environmental regulations, making the Guam Environmental Protection Agency the correct answer.
