Technology Based Numerical Limitations for Nutrients in Permits

TECHNOLOGY BASED NUMERICAL LIMITATIONS FOR NUTRIENTS IN PERMITS

Nitrogen and phosphorus discharges throughout the Bay watershed have been shown to impact the water quality in the Bay and its tidal rivers. As a result, the Commonwealth embarked on a rulemaking process to establish [Regulatory] authority for controlling the discharge of total nitrogen and total phosphorus within the Virginia portion of the Chesapeake Bay watershed.

For the total nitrogen and total phosphorus annual waste load allocations approved by the State Water Control Board for the significant point source dischargers in the Virginia portion of the Chesapeake Bay Watershed, please see the following links:

Numerical limitations for total nitrogen and total phosphorus that are more restrictive than the Board approved numerical limitations included in the nutrient regulations may be needed for some discharges/watersheds, in order to meet the requirement of the Virginia Water Quality Standards or any applicable TMDL.
