CROMERR 101: Fundamentals for States, Tribes, and Local Governments
This self-directed, online course is designed for states, tribes, and local governments that administer EPA-authorized programs under Title 40 of the Code of Federal Regulations (40 CFR) and accept or wish to accept electronic reports. It consists of nine lessons.

CROMERR Application Challenges and Solutions (PDF) (19 pp, 305K)
This document presents common challenges identified in CROMERR applications received by EPA. For each challenge, it presents the CROMERR issue or deficiency, examples of effective approaches to resolving them, and the EPA-approved systems that use these effective approaches. This document should be used by state and local environmental agency officials and system managers to help them in planning systems that are CROMERR compliant, preparing CROMERR applications, and, for submitted applications, responding to notices from EPA of issues and deficiencies.

Challenge Question Second Factor Approach (PDF) (3 pp, 547K)
EPA has determined that to meet the CROMERR requirement, a system using PIN/password must be accompanied by some other identifier that, together with the PIN/password, will be sufficient to prove that the e-signature has not been compromised. One approach is to use the PIN/password in conjunction with a ‘second factor’ to create an e-signature. This document outlines the use of challenge questions as one approach to meeting this CROMERR requirement.
