MAERS Part 1 - Introduction to MAERS: Access, Navigation and the Source and Contact tabs
January 26, 2021 - 10:00 AM EST

In this webinar we will be discussing why MAERS is required for some facilities, what the data is used for and how the system works. We will talk about various resources available to the user and how to access the system. This webinar will finish up with how to navigate the system and what information is required for the Source and Contact tabs.


MAERS Part 2 – Setting the table: the Emission Unit, Reporting Group and Stack tabs
January 26, 2021 - 1:00PM EST

This webinar will include a brief synopsis of the Part 1 content; however the focus of this webinar will be on how to complete the Emission Unit, Reporting Group and Stack tabs. There are some emission units and process equipment that must be reported and some you may not have to worry about. The way you enter this information is important too, either making your reporting easier or harder. This webinar will set the table for your entire report.


MAERS Part 3 – The meat of it: the Activity and Emissions portion
January 28, 2021 - 10:00AM EST

This webinar will start with a brief synopsis of the Part 2 content. Part three of the series will focus on what information needs to be reported as an “activity” and how does that help MAERS calculate your emissions.  Most of the time, entering your information can be simple, but what if your emission unit has multiple activities and numerous pollutant emissions. We will discuss using MAERS calculated emissions vs your actual emissions. The end of the webinar will show you how to get your own reports out of the system.


MAERS Part 4 – Dessert is only for some people: additional reporting of control equipment
January 28, 2021 - 1:00PM EST

The U.S. Environmental Protection Agency has mandated additional information for control equipment be reported, but only some emission units at some facilities will need to complete this extra reporting. If you received notification of this additional reporting, this webinar will be a necessity for you to be able to complete your 2020 MAERS report.  This webinar will detail resources available to submit this information and walk you through various examples of what should be reported from some very straightforward examples to some complex situations. The webinar will end with a question and answer session designed to help facilities get the information they need.
