New Mexico Administrative Code Title 20 - ENVIRONMENTAL PROTECTION
I. Overview of NMAC Title 20 – Environmental Protection
Title 20 of the NMAC establishes rules and regulations for protecting New Mexico’s environment, administered primarily by the New Mexico Environment Department (NMED).
Key Areas of Regulation:
Air Quality Control (20.2) – Emissions standards, permitting, and air quality monitoring.
Water Quality Control (20.6) – Surface water, groundwater, wastewater, and stormwater regulations.
Hazardous Waste Management (20.4) – Storage, treatment, and disposal of hazardous waste.
Solid Waste Management (20.9) – Landfills, recycling, and municipal solid waste disposal.
Environmental Permitting and Enforcement (various chapters) – Permits, inspections, fines, and remediation orders.
Enforcement Mechanisms:
Administrative orders for compliance.
Civil penalties for violations.
Remediation and corrective action orders.
Permit revocation or suspension.
II. Illustrative Case Analyses under NMAC Title 20
Here are six detailed examples showing how Title 20 regulations have been applied, based on administrative enforcement actions, contested cases, and environmental disputes.
Case 1: In re Albuquerque Industrial Plant – Air Quality Violations
Background:
An industrial facility in Albuquerque exceeded its permitted emissions of nitrogen oxides (NOx) and particulate matter under NMAC 20.2.
Forensic/Regulatory Action:
NMED conducted inspections and measured emission levels.
Facility claimed measurement error, but repeated sampling confirmed violations.
Decision/Outcome:
NMED issued an administrative compliance order requiring immediate reduction in emissions.
Civil penalties were imposed, and the facility was required to install updated air filtration technology.
Significance:
Illustrates NMAC Title 20.2 enforcement.
Confirms that administrative orders carry legal weight even without court litigation.
Highlights use of repeated monitoring for enforcement.
Case 2: Wastewater Discharge Dispute – Santa Fe County
Background:
A small wastewater treatment facility discharged effluent exceeding permitted levels of nitrates and phosphates under NMAC 20.6.
Forensic/Regulatory Action:
NMED collected water samples and compared them to discharge permit limits.
The facility claimed compliance, but laboratory tests confirmed violations.
Decision/Outcome:
NMED issued a Notice of Violation (NOV) and required remediation.
Civil penalties were assessed, and facility operators were mandated to upgrade their treatment systems.
Significance:
Shows NMAC Title 20.6 in action.
Demonstrates administrative power to enforce water quality without immediate judicial intervention.
Highlights the importance of accurate recordkeeping by facilities.
Case 3: Hazardous Waste Storage – Albuquerque Chemical Plant
Background:
A chemical storage facility stored hazardous waste without proper containment as required by NMAC 20.4.
Forensic/Regulatory Action:
Inspectors observed leaking containers and inadequate secondary containment.
Risk assessment indicated potential groundwater contamination.
Decision/Outcome:
NMED ordered removal of waste, corrective measures, and mandatory staff training.
Fines were imposed, with repayment of cleanup costs required.
Significance:
Illustrates hazardous waste enforcement under NMAC 20.4.
Shows administrative authority to require remediation and financial penalties.
Case 4: Solid Waste Management Violation – Rural Landfill
Background:
A rural landfill accepted unauthorized waste, including tires and electronics, violating NMAC 20.9.
Forensic/Regulatory Action:
NMED inspections confirmed the presence of prohibited waste.
Facility records showed misreporting of waste streams.
Decision/Outcome:
NMED issued an administrative compliance order to remove unauthorized waste.
Fines were levied and future operations conditioned on strict compliance.
NMED also mandated periodic third-party audits.
Significance:
Highlights enforcement in solid waste management under NMAC Title 20.
Demonstrates administrative remedies including fines, corrective action, and monitoring.
Case 5: Air Permit Dispute – Mining Operation
Background:
A mining company applied for an air quality permit. Community groups challenged the permit, claiming inadequate modeling under NMAC 20.2.
Forensic/Regulatory Action:
NMED reviewed emissions modeling, public comments, and environmental impact.
Independent technical review supported the need for additional control measures.
Decision/Outcome:
Permit approved conditionally, requiring additional dust suppression measures and ongoing monitoring.
NMED maintained authority to revoke permit if conditions were violated.
Significance:
Shows how public participation interacts with NMAC Title 20 permitting.
Highlights administrative balancing of economic development and environmental protection.
Case 6: Groundwater Contamination – Albuquerque Industrial Spill
Background:
Industrial chemicals leaked into groundwater from a manufacturing facility, potentially violating NMAC 20.6.
Forensic/Regulatory Action:
NMED conducted soil and water sampling.
Facility conducted its own investigation but was found non-compliant with reporting rules.
Decision/Outcome:
NMED issued an administrative order requiring cleanup and groundwater monitoring.
Civil penalties and cost recovery were imposed.
Ongoing compliance inspections ensured adherence to remediation plan.
Significance:
Illustrates administrative enforcement for water contamination.
Shows how NMAC Title 20 provides mechanisms to protect human health and natural resources.
III. Key Takeaways from These Cases
Administrative Enforcement Dominates:
Most Title 20 actions are resolved through NMED administrative orders, rather than formal court litigation.
Multiple Regulatory Areas:
Air (20.2)
Water (20.6)
Hazardous waste (20.4)
Solid waste (20.9)
Civil Penalties & Remediation:
Fines, cleanup costs, and mandated upgrades are common.
Administrative orders carry legal weight and can be enforced in court if ignored.
Public Participation Matters:
Community challenges and public comments influence permit conditions.
Demonstrates quasi-judicial processes within the administrative system.
Preventive Measures Emphasized:
Ongoing monitoring, audits, and reporting requirements are standard.
Facilities are incentivized to comply proactively to avoid penalties.
