An Act to amend and reenact §
62.1-44.38
of the Code of Virginia, relating to certain data from water users; water use consumption for domestic, commercial, and industrial purposes and from data centers.
Be it enacted by the General Assembly of Virginia:
1. That §
62.1-44.38
of the Code of Virginia is amended and reenacted as follows:
§
62.1-44.38
. Plans and programs; registration of certain data by water users; advisory committees; committee membership for federal, state, and local agencies; water supply planning assistance.
A. The Board shall prepare plans and programs for the management of the water resources of the Commonwealth in such a manner as to encourage, promote, and secure the maximum beneficial use and control thereof. These plans and programs shall be prepared for each major river basin of the Commonwealth, and appropriate subbasins therein, including specifically the Potomac-Shenandoah River Basin, the Rappahannock River Basin, the York River Basin, the James River Basin, the Chowan River Basin, the Roanoke River Basin, the New River Basin, and the Tennessee-Big Sandy River Basin, and for those areas in the Tidewater and elsewhere in the Commonwealth not within these major river basins. Reports for each basin shall be published by the Board.
B. 1. In preparing river basin plan and program reports enumerated in subsection A, the Board shall (i) estimate current water withdrawals and use for agriculture, industry, domestic use, and other significant categories of water users; (ii) project water withdrawals and use by agriculture, industry, domestic use, and other significant categories of water users; (iii) estimate, for each major river and stream, the minimum instream flows necessary during drought conditions to maintain water quality and avoid permanent damage to aquatic life in streams, bays, and estuaries; (iv) evaluate, to the extent practicable, the ability of existing subsurface and surface waters to meet current and future water uses, including minimum instream flows, during drought conditions; (v) evaluate, in cooperation with the Virginia Department of Health and local water supply managers, the current and future capability of public water systems to provide adequate quantity and quality of water; (vi) estimate, using a data-driven method that includes multiple reasonable assumptions about supply and demand over varying time frames, the risk that each locality and region will experience water supply shortfalls; and (vii) evaluate hydrologic, environmental, economic, social, legal, jurisdictional, and other aspects of each alternative management strategy identified.
2. The Board shall direct the Department of Environmental Quality (the Department) in its facilitation of regional water planning efforts. The Department shall (i) ensure that localities coordinate sufficiently in the development of regional water plans; (ii) provide planning, policy, and technical assistance to each regional planning area, differentiated according to each area's water supply challenges, existing resources, and other factors; and (iii) ensure that each regional plan clearly identifies the region's water supply risks and proposes strategies to address those risks.
3. When preparing drought evaluation and response plans pursuant to subdivision 1, the Board shall recognize the localities that include any portion of the service area of a water supply utility in the Commonwealth that uses the Potomac River as a water supply source as a distinct drought evaluation region. Such plans shall incorporate the provisions of the Metropolitan Washington Water Supply and Drought Awareness Response Plan: Potomac River System (2000), including provisions related to triggers, actions, and messages for the Potomac River drought evaluation region. Nothing in this subdivision regarding the incorporation of such provisions shall be construed to limit the authority of the Governor during a declared drought emergency.
C. The Board may, by regulation, require each water user withdrawing surface or subsurface water or both during each year to register, by a date to be established by the Board, water withdrawal and use data for the previous year including the estimated average daily withdrawal, maximum daily withdrawal, sources of water withdrawn, and volume of wastewater discharge, provided that the withdrawal exceeds one million gallons in any single month for use for crop irrigation, or that the daily average during any single month exceeds 10,000 gallons per day for any other user. Location data shall be provided by each user in a coordinate system specified by the Board.
Any water user required to register water withdrawal and use data pursuant to this subsection that provides water to another person offsite shall include in its report, submitted on its regular reporting schedule, the total volume of potable water and, reported separately, the total volume of reclaimed water provided during each month for each of the following categories: (i) a data center, as that term is defined in subdivision A 43 of §
58.1-3506
, with an air permit issued by the Department and (ii) to the extent available without utility billing system modifications, (a) domestic purposes, (b) commercial and industrial purposes, separately or combined as available, and (c) all other non-categorized purposes. Where monthly data is not available, such data may be submitted based on the total volumes provided during each quarter. For purposes of this subsection "reclaimed water" means water that has been treated and repurposed from wastewater or non-potable sources. Reclaimed water volumes shall not be aggregated with potable water volumes in any public reporting, summary, or planning document produced by the Board pursuant to this section.
D. The Board shall establish advisory committees to assist it in the formulation of such plans or programs and in formulating recommendations called for in subsection E. In this connection, the Board may include committee membership for branches or agencies of the federal government, branches or agencies of the Commonwealth, branches or agencies of the government of any state in a river basin located within that state and Virginia, the political subdivisions of the Commonwealth, and all persons and corporations interested in or directly affected by any proposed or existing plan or program.
E. The Board shall prepare plans or programs and shall include in reports prepared under subsection A recommended actions to be considered by the General Assembly, the agencies of the Commonwealth and local political subdivisions, the agencies of the federal government, or any other persons that the Board may deem necessary or desirable for the accomplishment of plans or programs prepared under subsection B.
F. In addition to the preparation of plans called for in subsection A, the Board, upon written request of a political subdivision of the Commonwealth, shall provide water supply planning assistance to such political subdivision, including assistance in preparing drought management strategies, water conservation programs, evaluation of alternative water sources, state enabling legislation to facilitate a specific situation, applications for federal grants or permits, or other such planning activities to facilitate intergovernmental cooperation and coordination.
2. That the provisions of this act shall become effective on January 1, 2027.
