Section 9VAC25-260-60 - Rise above natural temperature

Universal Citation: 9 VA Admin Code 25-260-60
Current through Register Vol. 41, No. 3, September 23, 2024

Any rise above natural temperature shall not exceed 3°C except in the case of Class VI waters (natural trout waters), where it shall not exceed 1°C. However, the board can, on a case-by-case basis, impose a more stringent limit on the rise above natural temperature. Natural temperature is defined as that temperature of a body of water (measured as the arithmetic average over one hour) due solely to natural conditions without the influence of any point-source discharge.
