EPA developed the National Strategy for the Development of Regional Nutrient Criteria (National Strategy) in June 1998. The strategy presents EPA's intentions to develop technical guidance manuals for four types of waters (lakes and reservoirs, rivers and streams, estuaries and coastal waters, and wetlands) and produce section 304(a) criteria for specific nutrient ecoregions by the end of 2000. In addition, the Agency formed Regional Technical Assistance Groups (RTAGs) which include State and Tribal Representatives working to develop more refined and more localized nutrient criteria based on approaches described in the waterbody guidance manuals. This document presents EPA's current recommended criteria for total phosphorus, total nitrogen, chlorophyll a, and turbidity for lakes and reservoirs in Nutrient Ecoregion IX (Southeastern Temperate Forested Plains and Hills) which were derived using the procedures described in the Lakes and Reservoirs Nutrient Criteria Technical Guidance Manual (U.S. EPA, 2000a).
