State: 9VAC25-740-150 Management of pollutants from significant industrial users
A reclamation system that receives source water from a wastewater treatment works having SIUs shall not be permitted to produce reclaimed water meeting Level 1 standards, unless:
- The wastewater treatment works providing source water to the reclamation system is a publicly owned treatment works as defined in the VPDES Permit Regulation (9VAC25-31-10), and has a pretreatment program required by and developed in accordance with procedures described in Part VII of the VPDES Permit Regulation (9VAC25-31-730 et seq.); or
- The reclamation system has evaluated source water from the treatment works for pollutants of concern discharged by SIUs to the treatment works, and has confirmed that such pollutants shall not interfere with the ability of the wastewater treatment works to produce source water suitable for the production of reclaimed water meeting Level 1 standards and any other standards required in accordance with 9VAC25-740-70 D. All such evaluations by the reclamation system shall be submitted to the board for review and approval, and shall be repeated for each new SIU that proposes to discharge to the treatment works prior to commencing such discharge.
