  • Requires Virginia Pollutant Discharge Elimination System Permits issued after July 1, 2026, to include low-flow protection rules if they divert sewage or reclaimed water for reuse and exceed 500,000 gallons per day.

Who It Names or Affects

  • People who need permits for taking water from the Occoquan Reservoir, River, Bull Run, or their tributaries.
  • Publicly owned treatment works that divert sewage or reclaimed water for reuse.

Terms To Know

Virginia Pollutant Discharge Elimination System Permit

Such permits shall require that the permittee provide or secure sufficient offstream storage to augment instream flow during low-flow periods in an amount equal to the amount that the permittee's consumptive use exceeds 500,000 gallons per day. The permit shall specify the instream flow volume at which low-flow protection is to be implemented.

B.

2.

Permittees may comply with the requirements of this
section
subsection
by: (i) constructing or acquiring facilities for offstream storage of water that may be used to replace their consumptive use withdrawals exceeding 500,000 gallons per day during low-flow periods; (ii) purchasing storage capacity in facilities owned by another entity, sufficient to replace their consumptive use withdrawals exceeding 500,000 gallons per day during low-flow periods; or (iii) agreeing to a permit condition limiting consumptive use to not more than 500,000 gallons per day during low-flow periods as designated in the permit.
