To Protect, Preserve, and Enhance the Air Resources for Current and Future Navajo Generations. 

The air monitoring section is responsible for operating and maintaining the AQCP ambient air monitoring network on the Navajo Nation. The AQCP uploads collected air quality data to U.S. EPA’s Air Quality Systems (AQS) database; which is then used to determine compliance with the National Ambient Air Quality Standards (NAAQS) to protect human health and the environment.  The NAAQS consists of six criteria pollutants for which the Navajo Nation monitors four of these criteria pollutants: particulate matter 2.5 (PM2.5, or airborne particles 2.5 microns in diameter and smaller), ozone (O3), sulfur dioxide (SO2), and nitrogen dioxide (NO2).  The program currently has two monitoring stations on the Navajo Nation, one in Shiprock, NM and the other in Nazlini, AZ.  The Shiprock station is equipped with federal reference method gaseous analysers that monitor for ground-level O3, SO2 and oxides of nitrogen (NO, NO2, NOx). The Shiprock station is also equipped with a 10-meter meteorological tower which measures wind speed, wind direction, relative humidity, temperature, precipitation and solar radiation. The Nazlini station consists of collocated federal reference method monitors that measure filter-based PM2.5.

The AQCP also responds to community concerns regarding impacts to residential air quality. Upon request, the AQCP mobile air monitoring unit can be deployed for up to a one (1) year duration and is equipped to measure gaseous pollutants and particulate matter. Requests for community air monitoring is considered on a case by case evaluation, please contact the program for further information.

Open Burn

The purpose of the Navajo Nation Open Burn Regulations (“NNOBR”) is to protect the health, safety and general welfare of all residents on the Navajo Nation.  The regulations are intended to discourage open burning disposal practices where alternative methods are feasible and practicable.  These regulations apply to all persons and all property within the Navajo Nation, as defined in 7 N.N.C. C §254(A).  The NNOBR are promulgated under the authority of § 1103 of the Navajo Nation Air Quality Pollution Prevention and Control Act, 4 N.N.C. §§1101-1162.  Open Burning is defined as the burning of hazardous materials and household waste that releases chemicals into the air without controls.  Open Burning is prohibited within the Navajo Nation unless an Open Burn permit is obtained, or the event is an exempted activity.  Individuals who conduct open burning without a permit, or are within a ten mile radius of a transfer station/disposal facility are in violation of NNOBR and will be subject to field citations or other penalties. 

Fires set for agriculture, forestry and silvicultural, and cultural and traditional purposes are an exempted activity under the open burn regulations.  However, they must be registered with the NNEPA-AQCP for information purposes only.  Agricultural burning refers to the burning of vegetation from an agricultural activity necessary for disease or pest control or for crop propagation and or crop rotation, also includes branding livestock. Agricultural burning does not include the burning of manure.  Forestry and silvicultural burning refers to the burning of vegetation debris from a forestry or silvicultural activates necessary for disease or pest control to reduce fire hazards, reforestation, or ecosystem management. Forestry or silvicultural burning does not include the burning of manure.  Fires set for cultural and traditional purposes means the open burning is conducted pursuant to Navajo beliefs, customs and practices that have been passed through generations, usually orally or through practices.  Registration forms for agriculture, forestry and silvicultural, and cultural and traditional burning can be obtained from the NNEPA-AQCP website, and submitted through email, fax or in person.

Indoor Air Quality

Indoor Air Quality refers to the quality of the air within and around a home or structure and how it affects the health of its occupants.  Over the past couple years the NNEPA AQCP has been developing an indoor air quality component to the program by conducting indoor air quality assessments within Navajo homes and developing outreach material on wood and coal use.  The program has developed live read public service announcements, Navajo specific brochures and factsheets, a webpage specific to wood and coal use, and a five minute video in the Dine language regarding best burning practices.  The program has committed to completing ten (10) in-home Indoor Air Quality (IAQ) assessments on the Navajo Nation each year.  The assessment includes gamma radiation levels, particulate matter readings, carbon monoxide level, relative humidity and temperature to address mold issues.  The program works with the homeowner to interpret the results and helps them to develop best practices that will improve air quality.
