Resources for State, Local, and Tribal Authorities

Introduction

This page offers some resources to State, Local, and Tribal Authorities (SLTs) who are either interested in onboarding with CAERS or are considering joining and would like to provide feedback as CAERS functionality continues to be developed.  The use of CAERS is not mandatory for SLTs. 

Joining the Product Design Team

Our Product Design Team (PDT) is composed of staff from EPA and SLT air programs.  We meet every two weeks to:

  • Discuss SLT and federal program requirements towards CAERS development (via discussions or through R&D projects)
  • Obtain periodic updates on CAERS development
  • Provide feedback towards CAERS improvements and new functionality   

We are always interested in having new SLTs become members of our CAER Product Design Team (PDT).  By joining the PDT you are not committing to using CAERS.  However, your feedback on PDT calls will help improve CAERS, and it may become a good fit for you in the future.   If you are interested in joining the PDT, please reach out to one of the PDT co-chairs:

Obtaining a CAERS Test Account

If you are considering onboarding with CAERS but are not sure yet, or not ready to do so, you may get a test account to help you understand how your SLTs data will look in CAERS, and what kinds of edits, additions, and corrections you may want to apply to your data before they are pulled into CAERS.  By learning how CAERS will handle your data, you may get a good sense of how CAERS works now, and the types of customizations you would need (for example, SLT-specific QA checks, SLT-specific emission factors you'd want to add to the compendium, etc.).  To request more information about obtaining a test account, reach out to Julia Gamas (gamas.julia@epa.gov).

Onboarding with CAERS

While SLTs can onboard at any time if they would like to adopt CAERS as is, we know many SLTs will likely need some customizations.  CAERS has been created so that SLT modules can be added, rather than hard coding any new SLT requirements. 

The following document may help you view your current SLT reporting system, method, and/or tools within the overall CAERS scheme:

  • CAER SLT Cases 1 to 4 (pdf) (156.75 KB, 01/26/2023)

The following document lays out the general steps to take to onboard with CAERS:

  • Combined Air Emissions Reporting System Roadmap for SLT Partner Onboarding (docx) (180.82 KB, 11/07/2022)

The following document describes CAERS data governance:

Funding

Exchange Network Grants to assist SLTs in their adoption of CAERS are available every year and are due early Spring.  For example, an SLT may need funding to: build out their data retrieval using the CAERS API, create a workflow to transform their current data intake templates for their users to be able to upload data into CAERS, require additional staff time to work with EPA to adopt CAERS.  SLTs may benefit from work done by previous SLTs grant recipients.
