Introduction INTRODUCTION Background: The goal of the Clean Water Act (CWA) is to restore and maintain the chemical, physical, and biological integrity of the Nation’s Waters (Water Polution Control Federation 1987). As the state’s environmental agency, the Alabama Department of Environmental Management (ADEM) establishes water quality standards and implements management programs to meet these goals. The ADEM conducts monitoring to evaluate the effectiveness of these programs and to determine water quality status and trends. Section 303(d) of the CWA (§303(d)) requires that each state identify those waters that do not currently support water quality standards or designated uses. For each waterbody on the list, the state is required to establish a Total Maximum Daily Load (TMDL) for the pollutant or pollutants of concern at a level necessary to meet the applicable water quality standards. Nationwide, this process has been most effective at addressing impairments caused by point source discharges. However, pollutants from point sources only accounted for 47 (15%) of the 303 total sources on Alabama’s 2002 §303(d) list. In 2003, the USEPA linked CWA §319 funding to the TMDL process to begin to implement nonpoint source control activities more effectively. To obtain best management practice implementation funding, a Watershed Plan that addresses an approved TMDL must be developed. The Watershed Plan must describe a holistic strategy to improve, maintain, or protect water quality, it must address both point and nonpoint source issues within the watershed, and it must describe how nonpoint source load reductions will be achieved. ADEM NPS Management Strategy: In 1996, the Alabama Department of Environmental Management (ADEM) adopted an adaptive watershed management strategy to synchronize water quality monitoring and management. Concentrating planning and implementation efforts within one basin group allows a focused review of available data and provides coordinated water quality monitoring and assessment efforts, efficient implementation of pollution control activities on a geographic basis, and consistent and integrated decisionmaking for awarding CWA §319 funds. Since 1998, ADEM’s voluntary, incentive-based nonpoint source management program has been implemented through ten basinwide Clean Water Partnership Projects. Through these partnerships, management plans are developed and implemented for each basin. The partnerships allow for participation and collaboration among community-based groups, government agencies, industry, farms, forestry, special interest groups, and individual citizens. ADEM NPS Monitoring Strategy: A 2-tiered monitoring approach is used to identify impaired waters, determine the causes and sources of impairment, and evaluate the effectiveness of pollution control activities. This approach concentrates ADEM’s resources in areas with the greatest potential for impairment and where more intensive monitoring is required. Tier I monitoring, completed using ADEM’s basinwide screeninglevel assessment methods, is conducted on a repeating 5-year management cycle during 1
