Subject: I & I report guidance.
Importance: Normal
Hi there. Here is some information that you should find helpful in deciding which elements should be in your annual reports, along with a suggested outline and format for the reports.
DEQ has no guidelines for these reports. However, I think if we can get everyone to follow the CMOM program (EPA guide for evaluating Capacity, Management, Operation and Maintenance at sanitary sewer collection systems), it could really help to streamline reviewing the reports, as well as establish an even “playing field” so that we treat all facilities equally. The following link will take you to the EPA web page where you can view and download the document:
http://water.epa.gov/polwaste/npdes/sso/upload/cmom_guide_for_collection_systems.pdf
The checklist at the end is a really good tool to see what you could do and identify areas needing improvement. We use the CMOM program as a recommended approach for managing a collection system.
If you want a really short answer, the TOC for the checklist can be used as an outline for the information we would like to see:
