What is the total phosphorus (TP) limit for a site?

• A. 0.25 lbs/ac/yr
• B. 0.41 lbs/ac/yr
• C. 0.50 lbs/ac/yr
• D. 0.75 lbs/ac/yr

Answer: (B)

The total phosphorus (TP) limit for a site is critical in stormwater management as it helps protect water quality in nearby bodies of water by reducing nutrient pollution, which can lead to harmful algal blooms and adverse ecological impacts. In Virginia, the established total phosphorus limit for new development and redevelopment projects is 0.41 pounds per acre per year. This specific limit is part of the state's effort to manage stormwater runoff effectively while adhering to the Chesapeake Bay TMDL (Total Maximum Daily Load) requirements. Adhering to this limit helps ensure that phosphorus loading does not exceed levels that can harm aquatic ecosystems.
