What is a 305 B report?

What are impaired waters?
Waters are assessed as impaired when an applicable water quality standard is not being attained. Impaired waters require a total maximum daily load (TMDL) or alternative restoration plan to reduce pollutant loadings and restore the waterbody.
What does TMDL mean?
Total Maximum Daily Loads
Overview of Total Maximum Daily Loads (TMDLs)
What is a point source discharge?
The U.S. Environmental Protection Agency (EPA) defines point source pollution as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack.” Some factories discharge their effluents directly into a waterbody.
How does the Clean water Act deal with impaired water bodies?
When a water body is impaired, a plan is required to restore the waters to a healthy condition. A TMDL implementation plan includes strategies for reducing the pollutants, including specific allocations for permit holders and reductions for nonpoint sources.
What is the Chesapeake Bay TMDL?
What is the Bay TMDL? On December 29, 2010, the U.S. Environmental Protection Agency established the Chesapeake Bay Total Maximum Daily Load (TMDL). The TMDL is a historic and comprehensive “pollution diet” to restore clean water in the Chesapeake Bay and the region’s streams, creeks, and rivers.
Who determines TMDL?
EPA
Once the TMDL for a pollutant has been determined by the state environmental agency, the report establishing the TMDL is submitted to the U.S. Environmental Protection Agency ( EPA ) for their approval. After the EPA has approved the TMDL, the next step is the development of an implementation plan.
What is the difference between point and nonpoint sources?
The United States Environmental Protection Agency (EPA) defines point source pollution as any contaminant that enters the environment from an easily identified and confined place. Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area.
What are 5 examples of point pollution?
EXAMPLES OF POINT SOURCE POLLUTION
- Industrial plants/factories (e.g., oil refineries, pulp and paper mills, chemical manufacturers, automobile manufacturers, food processors, pharmaceutical manufacturers) Pollutants: oil, thermal pollution, toxic chemicals, heavy metals, pharmaceuticals.
- Sewage Treatment Plants.
What is Section 303 D of the Clean Water Act?
