Aquatic Resource Alteration Permit (ARAP) Frequently Asked Questions (FAQ) - NEW February 21, 2008
An Aquatic Resources Alteration Permit (ARAP) is required for projects that will physically alter surface waters of the state (streams, wetlands, lakes, etc.). Examples of alterations that may require an ARAP include dredging, bank sloping or stabilization, water withdrawals, wetland filling, and road and utility crossings of waters. A list of Frequently Asked Questions has been compiled for your assistance.
Water Reuse InventoryIn 2007, the Center for the Management, Utilization and Protection of Water Resources and the Tennessee Department of Environment and Conservation (TDEC) distributed the second annual survey of Tennessee wastewater treatment utilities (only those that are legally allowed to handle 0.1 million of gallons or more of water per day [mgd]) to find out which ones were using water conservation and water reuse practices. A survey like this is important to Tennessee as it faces strong pressures on its water resources from human use.

The Known Exceptional Tennessee Waters
The Division of Water Pollution Control has compiled a partial list of exceptional Tennessee waters based on characteristics set forth in the regulation by the Tennessee Water Quality Control Board. In general, these characteristics are streams with good water quality, important ecological values, valuable recreational uses, and outstanding scenery. Wherever possible, the Division has utilized objective measures to apply these characteristics and the basis for each listing is provided.

Watershed Management Plans
Watershed Water Quality Management Plans are prepared in Year 5 of the watershed management cycle. These watershed plans include a general watershed description, water quality assessment summary results, inventory of point and nonpoint sources, water quality concerns voiced by citizens at public meetings, federal, state, and local initiatives, and management strategies. A public meeting is held to discuss the draft plans with local citizens, elected officials, and the regulated community.
