The department encourages communities, sewer and water districts, counties, and nonprofits with Clean Water State Revolving Fund (CWSRF) eligible needs to begin developing and gathering documentation in support of the upcoming CWNS.
The Missouri Department of Natural Resources has published the Procedure for Applying Mussels Absent Ammonia Criteria in Missouri Surface Waters. This document describes the performance-based approach the Missouri Department of Natural Resources will use to determine the application of mussels absent criteria in Missouri surface waters (excluding the Mississippi and Missouri Rivers). This approach is designed to ensure appropriate ammonia criteria are applied to protect the aquatic life designated use in receiving and downstream waters. This document details the process, minimum data requirements, and decision-making framework.
