Protecting New Mexico's Environment and Natural Resources


Otero Mesa

Massachussetts v. EPA (2007)

The United States Supreme Court ruled 5-4 in favor of New Mexico and eleven other states and various municipalities and environmental groups in Massachussetts v. EPA.  The lawsuit focused on a section of the Clean Air Act that requires the administrator of the U.S. Environmental Protection Agency “shall” set emission standards for “any air pollutant” from new motor vehicles which cause or contribute to air pollution that may be reasonably anticipated to endanger public health or welfare.  The Court held that greenhouse gases such as carbon dioxide are pollutants under the Clean Air Act and EPA has authority to regulate those gases in motor vehicles.  The Court also held that EPA can decide not to regulate greenhouse gases “only if it determines that greenhouse gases do not contribute to climate change, or if it provides some reasonable explanation as to why it cannot or will not exercise its discretion to determine whether they do.”

Department of Energy (DOE) sites

Waste Isolation Pilot Plant

The State regulates the Waste Isolation Pilot Plant (WIPP) through a permit issued under the Hazardous Waste Act. From time to time the DOE seeks to amend that permit, usually to change methods of waste characterization and management. The Attorney General’s Office reviews these proposed amendments and provides comments to the Environment Department to insure that the public health and safety is protected.

Los Alamos National Laboratory

The Attorney General’s Office focuses on issues off environmental restoration (i.e., cleanup) of Los Alamos National Laboratory (LANL). LANL is regulated by a Hazardous Waste Act permit issued by the Environment Department (NMED). Cleanup is covered by the Hazardous and Solid Waste (HSWA) module of the permit. The Attorney General’s Office assists NMED in enforcement of its permits. In addition, the Attorney General’s Office and the Office of the Natural Resources Trustee have begun discussions with DOE to resolve natural resource damage claims at LANL.

Sandia National Laboratories

The Attorney General’s Office has been supporting the New Mexico Environment Department in negotiations regarding the cleanup of hazardous waste. A proposed settlement is currently under review.

Natural Resource Damages


The Attorney General represents the Office of the Natural Resources Trustee (ONRT), which is empowered to seek recovery for injury to natural resources under the federal CERCLA statute. Working with the ONRT staff, we have formed a cooperative relationship with the U.S. Department of the Interior and the U.S. Department of Agriculture under which the three agencies are jointly pursuing natural resource damage claims in cases where state and federal interests are involved.

Molycorp, Inc. Questa Mine-Mill site

The state and federal trustees have negotiated an agreement with Molycorp, Inc., under which Molycorp, will finance the cost of assessing damages to natural resources in cooperation with the state and federal trustees. It is hoped that this cooperative assessment will lead to a cooperative agreement to restore or replace damaged natural resources.

Phelps Dodge Inc. Chino and Tyrone sites

The Attorney General’s Office and the ONRT along with the federal trustees have negotiated an agreement with Phelps Dodge with a goal of creating a cooperative approach to the assessment of natural resource damages from mining operations.

Burlington Northern Santa Fe Railroad – Clovis site

The Attorney General’s Office and the ONRT have negotiated a settlement agreement with BNSF for natural resources damages at this site.

Burlington Northern Santa Fe Railroad – Albuquerque tie treater site

The Attorney General’s Office and the ONRT have negotiated a settlement with the BNSF for natural resources damages at this site.

Environmental Crimes Unit

In recognition of the vital importance of maintaining New Mexico’s precious environment, the Attorney General’s Office formally established the first ever Environmental Crimes Unit in the Water, Environment and Utilities Division. Working with the Prosecutions Division of the Attorney General’s Office, this unit will investigate and criminally prosecute violations of state environmental laws.

Hector Villa, Frontera Environmental

After his sentencing 5/9/02 for 8 felony counts pursued under New Mexico’s Water Quality Act, this defendant appealed his conviction to the state Court of Appeals. The defendant was found guilty by a Las Cruces jury of 8 felony counts for violating a permit. The Court of Appeals entered a decision October 10, 2003, reducing these crimes to attempts at violating a permit, thereby reducing the felonies to misdemeanors. The case was remanded to the Third Judicial District Court and he as resentenced.

Although the decision reduced the criminal liability for the defendant, the Court did not absolve defendant of all guilt for the acts he committed. This case is the first litigated conviction of an environmental criminal in New Mexico, all other prior convictions having been established through plea agreements. It is also the first time an environmental consultant has been held accountable for the advice and direction given to a business entity, in this case Valley By-Products, a Texas rendering plant which was illegally dumping its waste in New Mexico. The case presented the first opportunity to create criminal environmental case law in New Mexico, and gives future prosecutions guidelines for pursuing justice under the environmental laws of our state.
