EPA Webinar – Easy Modeling to Assess and Address Near-Road Air Quality – April 20

We received the notice below by email from the EPA Environmental Justice Listserv.  For a heads up on what how their modeling tool works and what it does, check out this video.



Easy Modeling to Assess and Address Near-Road Air Quality

Thursday 20 April 2017 at 2pm – 3:30pm Eastern

Register Here Today!


Sometimes the groups most exposed to near-road air pollution are also the most disadvantaged and marginalized to do something about it. Land values near roads are typically devalued because of noise, pollution, and visual blight. Long-term exposure to near-road pollution can have serious health effects, contributing to diseases such as cancer and respiratory illness; and short term exposure can exacerbate existing conditions, like childhood asthma attacks. Children, elderly, and folks with pre-existing conditions are especially sensitive to roadway pollution.

This webinar will present the Community-LINE Source Model (C-LINE) (https://www.epa.gov/healthresearch/community-line-source-model-c-line-estimate-roadway-emissions): a scientifically sound, near-road air pollution model that plays almost like a video game, available to any user with a computer or tablet.

C-LINE allows users to not only evaluate what is going on in their local area, but also what might happen if things change, such as from increases in traffic or diesel trucks cutting through town. Users can easily manipulate model inputs to also examine upwind and downwind effects, or estimate the areas most influenced annually by near-road pollution. In addition to roads, railways and railyards, ports, ships, and industrial sources also influence near-source neighborhoods.

The model is being further developed to include these and other sources for public use. Would you use this model? How? How might we help you do that? Learn more in this interactive webinar!

C-Line Webinar – Estimating Roadway Emissions in Communities with EJ Concerns


  • Betsy Smith is a research biologist in the EPA Office of Research and Development. She has worked for the Agency for 20 years primarily in the areas of interdisciplinary science using spatial analysis to identify patterns and trends that can inform local- to national-scale decision-making. Betsy is currently the lead for EPA’s Sustainable Port Communities Study.

  • Tim Barzyk is a research scientist at the EPA. Tim works with community organizations, state and local agencies, EPA Regions and Program Offices, and academic partners to develop and apply near-source air quality models, citizen science portable sensor technologies, and decision analysis methods for use in local scale environmental health assessments. While focused on environmental health, his research acknowledges that local values and knowledge about social, environmental, and economic conditions must inform the assessment process in order to support evidence-based decision making by local residents, policy makers, or commercial interests to improve environmental conditions.

  • Vlad Isakov is a research scientist at the EPA. His current research focuses on the development and testing through applications and innovative approaches to model spatially and temporally resolved air quality concentrations in support of exposure and health studies.


If you are not already a member, the Office of Environmental Justice would like to invite you to join the EJ ListServ. The purpose of this information tool is to notify individuals about activities at EPA in the field of environmental justice. By subscribing to this list you will receive information on EPAs activities, programs, projects grants and about environmental justice activities at other agencies. Noteworthy news items, National meeting announcements, meeting summaries of NEJAC meetings, and new publication notices will also be distributed. Postings can only be made by the Office of Environmental Justice. To request an item to be posted, send your request to environmental-justice@epa.gov and indicate in the subject “Post to EPA-EJ ListServ”

Come to the IVAN Air Monitoring Launch Friday, Sept 30 in Heber CA

Comite Civico Del Valle and their partners are doing AMAZING citizen science work in the Imperial Valley. Come celebrate with them tomorrow, Friday, September 30 in Heber, California and learn about their 40 station air monitoring network.

Heber is less than two hours east of San Diego, California and under an hour from Yuma, Arizona. Check out the links below for more information.

EPA to release EJScreen 2016 – sign up for a webinar preview today!

Just received via email from the EPA EJ folks – 

Find out what you can do with the new and improved EJSCREEN, due for release later this month!

Register now for a webinar preview of the tool’s new features, and to share your EJSCREEN experiences with EPA and your EJ colleagues.

EJSCREEN is EPA’s online tool for environmental justice mapping and screening. Based on your feedback, with the updated EJSCREEN, you will now be able to:

  • Explore NATA environmental indicators for cancer risk, respiratory, and diesel PM

  • View EJ map data for Census block groups, tracts, and counties

  • Easily save sessions and print maps

  • Compare two maps side-by-side

  • Use EJSCREEN for Puerto Rico

  • and much more…

EJSCREEN webinar dates: 

  June 28 (2 pm EST)

  June 30 (4 pm EST)

  July 11 (3 pm EST)

New! Webcast on Using EJScreen and the National Equity Atlas for Environmental Justice Analyses and more

The EPA Office of Environmental Justice and the American Planning Association just released a Webcast that every EJ organization should check out.

It focuses on two great tools – the EPA EJSCREEN environmental justice screening and mapping tool; and the National Equity Atlas, a comprehensive data resource to track, measure, and make the case for inclusive growth, developed by PolicyLink and the Program for Environmental and Regional Equity (PERE).

EJSCREEN is an easy-to-use mapping tool that shows and calculates indexes for environmental and demographic data, and can be used for EJ analyses of communities or entire cities.

The National Equity Atlas just added data that will be of great interest to Moving Forward Network members, the Air Pollution Exposure Index.  The National Equity Atlas tool can show air pollution in a city by race, ethnicity, and by poverty level; can compare two cities, show unequal burden, and much more.

Presenters are Sarah Treuhaft, Director of Equitable Growth Initiatives at PolicyLink, and Carlton Eley and Kevin Olp with the EPA Office of Environmental Justice.
