Clean Air Program

With five air monitoring sites located within tribal jurisdictional boundaries in Oklahoma, the CNEP Clean Air Program operates one of the largest tribal air monitoring networks in the country. Criteria pollutants being monitored include ozone, carbon monoxide, sulfur dioxide, nitrogen oxides and particulate matter. Meteorological parameters monitored include temperature, humidity, wind speed and wind direction, and precipitation. They also operate a mobile monitor that rotates to various tribes and pueblos within Region 6; it is equipped to monitor ozone, particulate matter and meteorological parameters. The Stilwell site has been designated as a rural NCore site, and a Tekran continuous mercury analyzer is operated at this location. The Clean Air Program also participates in national monitoring programs such as CASTNet, IMPROVE, the Mercury Deposition Network (MDN) and the Ammonia Monitoring Network (AMoN). Past program initiatives have included GIS mapping of tribal trust land, creating an inventory of major and minor sources for ITEC member tribes, reviewing new and/or modified major source permits that have been issued by the state, and providing technical assistance and training to the member tribes related to air quality monitoring. 

The CNEP Air Program received a 2006 Clean Air Excellence Award in the category of Community Action. The award ceremony was held in May 2007 in Washington, D.C. at the National Museum of the American Indian.

Mobile Monitoring Station

The CNEP Clean Air Program, acting through ITEC, utilizes a tribal mobile monitoring station capable of evaluating particulate and ozone pollution on tribal lands within EPA Region 6.  This mobile station is equipped with a continuous PM2.5, PM10 and PMc monitor (Thermo 1405-D), a continuous ozone analyzer, and meteorological equipment.  The station provides near-real-time hourly averages of particulate matter and ozone for tribal communities.  In certain areas the unit is capable of wireless data transfers for data validation and posting of data to the U.S. EPA AQS database and AIRNow websites.  Hourly particulate, meteorological and ozone measurement information will be available to the public in near-real-time.  The mobile monitoring station is available to tribes on a first come first served basis.

Tribes currently on the waiting list:

  1. Laguna Pueblo
  2. Pueblo of Santa Ana

Exchange Network

The Exchange Network is a partnership of States, Tribes, Territories and EPA working together to provide better access to high-quality environmental data.  This is accomplished via automation of data sharing, standardization of data structures and real-time access through a secure Internet connection.

On December 1st, 2015, the Exchange Network Governance became part of E-Enterprise for the Environment. E-Enterprise for the Environment embraces a new model for collaborative leadership among environmental co-regulators, engaging with all interested and affected parties to achieve positive environmental, human health, and economic outcomes. It builds upon the foundation of the Exchange Network, recognizing the value of a proven communications and data analytics platform for sharing environmental information to foster informed decision-making.

The Exchange Network’s joint governance model of Federal, State, Territorial, and Tribal Partners working together has been adopted by E-Enterprise. Governance consists of the E-Enterprise Leadership Council (EELC), the E-Enterprise Executive Committee (EEEC), the E-Enterprise and Exchange Network Management Board (MB), and the E-Enterprise and Exchange Network Interoperability and Operations Team (IOT).  

The Tribal Governance Group (TGG) is an ad hoc group of tribal professionals working on various aspects of the EN whose primary purpose is to ensure representation of tribal perspectives and issues in the overall Exchange Network governance structure, and to foster and enhance tribal participation in the Network. TGG members also serve as representatives on the EELC, the MB and the IOT.

The Cherokee Nation is an Exchange Network grant recipient and participates on the TGG and the IOT.  Please visit for more information about tribal participation in the Exchange Network.

TAMS Steering Committee IAQ Implementation Plan - October 2015

IAQ Cover Letter_TAMSSC_20151020.pdf

TAMS Steering Committee IAQ Implementation Plan, 10-16-15.pdf


This document provides guidance for the Tribal Air Monitoring Support (TAMS) Center Indoor Air Quality technical priorities, services selection and implementation. The TAMS Steering Committee (SC) developed this concept paper with several objectives in mind:

  • To be responsive to tribal programs who have identified IAQ as a technical support priority
  • Provide the Institute for Tribal Environmental Professionals (ITEP) and the U.S. Environmental Protection Agency (EPA) recommendations and guidance on how to address tribal Indoor Air Quality technical support needs as identified by the tribes
  • Define priority areas of support that the TAMS center could offer or facilitate
  • Prioritize use of existing TAMS/ITEP/EPA IAQ resources and identify needed resources
  • Outline how tribal programs can access IAQ technical support
  • Identify a mechanism to incorporate tribal input to assure that TAMS Center IAQ services continue to be responsive to evolving needs and technology in the future.

Please feel free to send this out to anyone who might be interested.






TAMS Technical Needs Assessment Report - January 2015

TAMS Technical Needs Assessment Report, 1-21-15.pdf


The TAMS Steering Committee began the process of determining the needs of Tribal air programs from across the county in 2012.  The restructuring and subsequent discontinuance of the TAMS filter weighing service provided the  impetus for this assessment.  The SC also decide to gather information on what Tribal programs focus areas and support needs are at the same time.  The attached copy represents a coordinated effort by many people who were on and are now on the SC, as well as the TAMS Center Co-Directors and staff.  Further the ex-officio members contributed their knowledge and expertise to the process.  This SC Technical Needs Assessment Report and Implantation Plan truly represents the three partnerships the TAMS Center embodies. 


The report and implantation plan can and should be distributed widely.  Also note that the SC has taken steps to implement some of the action items.  The SC authored and  approved an Air Quality Filter Weighing Service Concept Paper and Air Quality Filter Weighting Guidance documents.  The SC will continue utilizing the information from the Technical Needs Assessment by implementing the action items identified and adding new ones as needed.


Thanks to everyone who participated in this successful effort.
