This dataset depicts TMDL watershed boundaries. A TMDL watershed is the area covered by a TMDL equation. It consists of one or more impaired streams that have an assigned Cause Group Code (CGC). The CGC is the link between the TMDL and the Assessment Report. The TMDL equations are stored in a table in the TMDL database. Currently, the database contains about 650 equations, which are set across the entire state. Each equation includes the Waste Load Allocation (WLA), which is the portion of the TMDL that accounts for pollution from point sources (permits). The WLA cannot be exceeded during permit reissuance or its TMDL equation must be modified.

The Virginia Water Protection Program (VWP) regulates activities in all surface waters which includes wetlands, streams, and open water. A permit (general permit coverage or individual permit) may be required in accordance with program regulations and State Water Control Law. This layer represents the project boundaries of both active and historic VWP General Permits and VWP Individual Permits for the state. The VWP permit's number, name, and regional office are among several attributes in this layer. The permit boundaries are drawn to represent the project boundary map provided by the permittee. The GIS data layers and maps produced by the Virginia Department of Environmental Quality (DEQ) are provided as a public resource. The Virginia Department of Environmental Quality has attempted to ensure the accuracy and completeness of the data. DEQ makes or extends no warranties of any type, expressed or implied, including but not limited to: appropriateness of use, accuracy, or completeness of data.

This dataset consists of the outfall locations for all Water
VPDES Individual and General Permits. 
There are nine (9) General Permits; Concrete Products; Domestic Sewage
Discharge; Noncontact Cooling Water, Nonmetallic Mineral Mining; Petroleum and
Hydrostatic Test; Potable Water Treatment Plant, Seafood Processing; Stormwater
Industrial; and Vehicle Wash and Laundry. 
There is a single VPDES Individual Permit, but these are designated as
either Major or Minor permits depending on the amount of flow or if they
require EPA review.

 

These data layer shows where discharges from the permitted
sites enters State Waters.  This dataset
will allow the public to find discharges to particular streams or relative to
where they live, work or play. 
Additional information about these discharges may be found by contacting
the DEQ regional office responsible for that area (https://www.deq.virginia.gov/Locations.aspx ).

The Virginia Water Protection Program (VWP) regulates activities in all surface waters which includes wetlands, streams, and open water. A permit (general permit coverage or individual permit) may be required in accordance with program regulations and State Water Control Law. This layer represents the Permittee Responsible Mitigation Area (PRMA) boundaries which certain VWP Permits require as part of their permit's compensation plan. The VWP permit's number, name, and regional office are among several attributes in this layer. The PRMA boundaries are drawn to represent the project's mitigation area boundary which is usually onsite of the VWP project.
