Grease Trap Regulations in New Mexico

Overview

New Mexico food businesses face strict fats, oils, and grease (FOG) rules. The rules protect city sewer systems in a dry climate. The New Mexico Environment Department (NMED) and the Water Quality Control Commission set state pretreatment standards. These standards control what can enter public sewers. Local water and sewer utilities enforce trap install and cleaning rules at the business level.

FOG-focused pretreatment programs have cut sewer overflows. That makes compliance important for restaurant owners across New Mexico, from Albuquerque to Las Cruces.

Governing Authorities

NMED runs the Federal Clean Water Act in New Mexico. It works to keep surface waters at state quality standards. The Water Quality Control Commission (WQCC) is the state water pollution control agency. It adopts the rules NMED runs for groundwater and surface water.

At the city level, enforcement goes to local water utilities and treatment plants:

• The Albuquerque Bernalillo County Water Utility Authority (ABCWUA) runs the Industrial Pretreatment Program required by EPA rules (40 CFR 403). It uses its Sewer Use and Wastewater Control Ordinance.
• Santa Fe County and Santa Fe Utilities enforce grease trap rules for food businesses in their service areas.
• Rio Rancho requires all commercial food businesses to install and maintain a grease trap through its Industrial Pre-treatment Program.
• Las Cruces and other cities run local FOG programs that match state water quality goals.

Key Requirements

New Mexico food operators must follow state pretreatment rules and local utility rules. In Albuquerque, traps must be cleaned when grease or solids hit 25% of trap depth, or at least every 90 days, whichever comes first.

Cleaning Frequency

• Big cities require cleaning at the 25% capacity mark or every 90 days at most.
• Busy kitchens may need monthly service.
• The 25% rule keeps grease out of city sewers.

Interceptor Sizing and Installation

• All new and existing food businesses must install grease traps sized and approved by local water authorities.
• Local building inspectors must approve trap size and type. Traps must meet the Uniform Plumbing Code.
• Big spots usually need outdoor traps.
• Small spots may use indoor traps under set rules.

Record-Keeping and Waste Manifests

• Keep cleaning and service records for at least three years. Show them when an inspector asks.
• Licensed haulers must take waste to approved sites. Each pickup needs a manifest.
• Service notes should include date, volume removed, and trap condition.

Fines and Enforcement

Breaking New Mexico FOG rules brings real costs. The ABCWUA can issue fines from $500 to $1,000 per day of violation. In bad or repeat cases, it can issue cease and desist orders, pull permits, or shut off sewer service.

Water authorities run routine inspections of food businesses to check sewer use rules and FOG policies. Enforcement tools include:

• Daily fines that build up until the issue is fixed.
• Required compliance plans for violations.
• Required install of properly sized outdoor traps.
• Cost recovery for blockages and overflows traced to the business.
• Permit loss and shut-down for serious cases.

Inspection fees and routine fees vary by city. Plan for compliance costs as part of business expenses to avoid much higher fines.

Major City FOG Programs

Albuquerque

The ABCWUA runs FOG rules through its Industrial Pretreatment Program and FOG Policy to protect city sewers. The Water Authority's Southside Water Reclamation Plant cleans wastewater before it goes into the Rio Grande. All food businesses must install approved grease traps and clean at the 25% mark or every 90 days. The ABCWUA runs routine inspections and enforces the rules with daily fines up to $1,000. Restaurant owners can call the Pretreatment Program at (505) 289-3419 for site-specific rules.

Santa Fe

Santa Fe County requires all restaurants, cafeterias, and other food prep sites in the sewer service area to install grease traps. This includes places now running without one, even if they have no history of blockages. After getting a noncompliance notice, owners must file plans or drawings to install a trap within three months. Once the county building inspection department approves, owners have up to six more months to finish the install. The county also enforces these rules for new builds and ownership changes. Santa Fe Utilities oversees sites inside city limits.

Las Cruces

Las Cruces food businesses must follow local pretreatment rules set by the city sewer utility. While exact FOG rules vary by city, commercial kitchens in Las Cruces follow standard practices: regular trap pumping, proper waste disposal through licensed haulers, and service records. The Las Cruces Fire Department runs business inspections that check grease management for commercial cooking. Owners can call the Community Development Department at (575) 528-3043 for site-specific rules.

Rio Rancho

Rio Rancho's FOG program requires all commercial food businesses to install and maintain a grease trap. The goal is to keep harmful waste out of the sewer system. The city's Industrial Pre-treatment Program runs routine inspections of food businesses. Rio Rancho also runs public outreach about grease disposal, especially around the holidays when home grease use jumps. The dry climate means sewer lines need close upkeep. Concentrated grease can form major blockages.

Frequently Asked Questions

How often must I clean my grease trap in New Mexico?

Cleaning timing depends on your city and business type. In Albuquerque and other big cities, traps must be cleaned when grease or solids hit 25% of trap depth, or every 90 days, whichever comes first. Busy restaurants may need monthly service. Smaller cafés may run on a quarterly schedule if they meet the 25% rule. Always check with your local water utility for exact rules. Keep cleaning records for at least three years.

What happens if grease from my restaurant causes a sewer blockage?

If your business is the source of a sewer blockage, you face several costs. These include fines, cleanup cost recovery, and possible permit loss. In Albuquerque, fines run from $500 to $1,000 per day of violation. Water authorities can trace blockages to the source. They may require a bigger trap, a written compliance plan, or a sewer shut-off for bad or repeat issues. Proper cleaning and records are your best defense.

Do I need a special license to dispose of grease trap waste in New Mexico?

As a food business owner, you do not need a disposal license. But you must use licensed haulers for all grease waste removal. These haulers must take FOG waste to approved sites and give you manifests. Save those manifests as part of your three-year records. Never dump grease waste into storm drains, on the ground, or in regular trash. Those acts break state and federal rules.
