What is a TMDL stream?
Total Maximum Daily Loads (TMDLs) are action plans to restore clean water. TMDLs examine the water quality problems, identify sources of pollutants, and specify actions that create solutions. They are adopted by the Regional Water Board as amendments to our Region’s Basin Plan.
What is a TMDL Watershed?
A total maximum daily load (TMDL) is a regulatory term in the U.S. Clean Water Act, describing a plan for restoring impaired waters that identifies the maximum amount of a pollutant that a body of water can receive while still meeting water quality standards.
What is an approved TMDL?
A Total Maximum Daily Load (TMDL) is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards.
What is a TMDL implementation plan?
The completion and Agency approval of a Total Maximum Daily Load (TMDL) is one step in the water regulatory or restoration process. A comprehensive TMDL implementation plan outlines management goals, projects, partners, priorities, schedule and finding along with tracking, monitoring and reevaluation processes.
What is the purpose of the TMDL assessments that are completed by state agencies?
A TMDL is both a quantitative assessment of pollution sources and pollutant reductions needed to restore and protect U.S. waters and a planning process for attaining water quality standards.
Can a TMDL regulate nonpoint source pollution?
The TMDL will also account for a margin of error and natural background levels of the pollutant. While the amount of WLAs under the TMDL can be enforced through NPDES permits, LAs are not enforceable against NPS polluters.
How has the EPA attempted to implement the TMDL program?
EPA envisions a TMDL program where States keep primary responsibility for implementing the program. EPA will help States meet their responsibilities by issuing and revising guidance, policy and regulations, and by providing technical assistance. EPA will tailor its level of support to individual State needs.
Does Clean Water Act cover nonpoint pollution?
The Clean Water Act (CWA) is designed with this kind of direct command and control regulation for point source pollution. However, command and control regulations through the CWA apply to nonpoint source pollution a lesser extent.
What is the difference between point and nonpoint pollution?
Point-source pollution is easy to identify. As the name suggests, it comes from a single place. Nonpoint-source pollution is harder to identify and harder to address. It is pollution that comes from many places, all at once.
Why is nonpoint source pollution potentially more harmful?
Point source pollution and nonpoint source pollution are both potentially harmful to the environment. For this reason, point source pollution is easier to regulate and therefore easier to control. This makes nonpoint source pollution potentially more harmful to the environment.
What is the difference between point and nonpoint water pollution?
