Virginia Administrative Code › Title 9 - ENVIRONMENT › Agency 25 - STATE WATER CONTROL BOARD › Chapter 260 - WATER QUALITY STANDARDS › Part II - Standards with More Specific Application › Section 9VAC25-260-187 - Criteria for man-made lakes and reservoirs to protect aquatic life and recreational designated uses from the impacts of nutrients

Current through Register Vol. 40, No. 24, July 15, 2024
A. The criteria in subsection B of this
				  section apply to the man-made lakes and reservoirs listed in this section.
				  Additional man-made lakes and reservoirs may be added as new reservoirs are
				  constructed or monitoring data become available from outside groups or future
				  agency monitoring.
B. Whether or
				  not algicide treatments are used, the chlorophyll a criteria apply to all
				  waters on the list. The total phosphorus criteria apply only if a specific
				  man-made lake or reservoir received algicide treatment during the monitoring
				  and assessment period of April 1 through October 31.
The 90th percentile of the chlorophyll a data collected at
					 one meter or less within the lacustrine portion of the man-made lake or
					 reservoir between April 1 and October 31 shall not exceed the chlorophyll a
					 criterion for that waterbody in each of the two most recent monitoring years
					 that chlorophyll a data are available. For a waterbody that received algicide
					 treatment, the median of the total phosphorus data collected at one meter or
					 less within the lacustrine portion of the man-made lake or reservoir between
					 April 1 and October 31 shall not exceed the total phosphorus criterion in each
					 of the two most recent monitoring years that total phosphorus data are
					 available.
Monitoring data used for assessment shall be from sampling
					 locations within the lacustrine portion where observations are evenly
					 distributed over the seven months from April 1 through October 31 and are in
					 locations that are representative, either individually or collectively, of the
					 condition of the man-made lake or reservoir.

C.
				  When the board determines that the applicable criteria in subsection B of this
				  section for a specific man-made lake or reservoir are exceeded, the board shall
				  consult with the Department of Game and Inland Fisheries regarding the status
				  of the fishery in determining whether or not the designated use for that water
				  body is being attained. If the designated use of the subject water body is not
				  being attained, the board shall assess the water body as impaired in accordance
				  with § 62.1-44.19:5 of the Code of Virginia. If the designated use is
				  being attained, the board shall assess the water body as impaired in accordance
				  with § 62.1-44.19:5 of the Code of Virginia until site-specific criteria
				  are adopted and become effective for that water body.
D. If the nutrient criteria specified for a
				  man-made lake or reservoir in subsection B of this section do not provide for
				  the attainment and maintenance of the water quality standards of downstream
				  waters as required in
				  9VAC25-260-10 C, the nutrient
				  criteria herein may be modified on a site-specific basis to protect the water
				  quality standards of downstream waters.
Statutory Authority: § 62.1-44.15 of the Code of
						Virginia; Clean Water Act (33 USC §
													1251 et seq.);
						40 CFR Part
						131.
The amended version of this section by
