Which entity is primarily responsible for the enforcement of laws related to the environment in Texas?

The Department of Environmental Quality is the entity primarily responsible for the enforcement of laws related to the environment in Texas. This agency oversees a wide range of environmental regulations, including air and water quality, waste management, and the protection of natural resources. The department's mission is to safeguard public health and the environment through effective regulation and enforcement, which makes it central to Texas's environmental law enforcement efforts.

While other entities play important roles in Texas government, they do not focus primarily on environmental laws. The Texas Railroad Commission, for instance, primarily regulates the oil and gas industry, which includes some environmental oversight but is not its main focus. The Comptroller of Public Accounts deals with financial and tax-related matters, and the Commissioner of the General Land Office manages state lands and mineral rights but does not specifically enforce environmental laws. Therefore, the Department of Environmental Quality is the correct choice for enforcement of environmental regulations in Texas.
