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.
