9 Va. Admin. Code § 25-740-50 - Exclusions and prohibitions

A. Exclusions. Exclusion from the requirements of this chapter does not relieve any owner of the operations identified in this section of the responsibility to comply with any other applicable federal, state, or local statutes, regulations, or ordinances. The following are excluded from the requirements of this chapter:

1. Activities permitted by the Virginia Department of Health (VDH), such as, but not limited to, septic tank drainfield systems and other onsite sewage treatment and disposal systems, and water treatment plant recycle flows. This exclusion does not apply to alternative onsite sewage systems as defined in 12VAC5-613 (Regulations for Alternative Onsite Sewage Systems) with an average daily sewage flow in excess of 1,000 gallons per day that are concurrently permitted by the department and VDH to allow sewage reclamation and reuse in addition to onsite sewage treatment and disposal.

2. Utilization of gray water, harvested rainwater, or stormwater.

3. Nonpotable water produced and utilized on-site by the same treatment works for facilities permitted through a VPDES or VPA permit. This includes the use of nonpotable water at the treatment works site for incidental landscape irrigation that is not identified as land treatment defined in the Sewage Collection and Treatment Regulations (9VAC25-790). The treatment works site shall include property that is either contiguous to or in the immediate vicinity of the parcel of land upon which the treatment works is located, provided such property is under common ownership or management with the treatment works. This exclusion does not apply to nonpotable water produced by treatment works authorized by the VPDES General Permit for Domestic Sewage Discharges Less Than or Equal to 1,000 Gallons Per Day (9VAC25-110).

4. Recycle flows within a treatment works.

5. Industrial effluents or other industrial water streams created prior to final treatment and used for water re-circulation, recycle, or reuse systems located on the same property as the industrial facility, provided:

a. The water used in these systems does not contain or is not expected to contain pathogens or other constituents in sufficient quantities and with a potential for human contact as may be harmful to human health;

b. These systems are closed or isolated to prevent worker contact with the water of the systems; or

c. Other measures are in place, including but not limited to, applicable federal and state occupational safety and health standards and requirements, to adequately inform and protect employees from pathogens or other constituents that may be harmful to human health in the water to be re-circulated, recycled or reused at the facility.

6. Land treatment systems described in the Sewage Collection and Treatment Regulations (9VAC25-790). Such use of wastewater effluent, either existing or proposed, must be authorized by a VPA or VPDES permit and must be on land owned or under the direct long-term control of the permittee.

7. Unintentional reuse.

8. Existing indirect nonpotable reuse projects that as of January 29, 2014, are authorized by a VPDES permit to discharge to surface waters of the state.

9. Existing indirect potable reuse projects that upon October 1, 2008, are authorized by a VPDES permit to discharge to surface waters of the state, and future expansions of these projects.

10. Direct injection of reclaimed water into any underground aquifer authorized by EPA under the Safe Drinking Water Act, Underground Injection Control Program (UIC), 40 CFR Part 144; or other applicable federal and state laws and regulations.

B. Prohibitions. The following are prohibited under this chapter:

1. Direct potable reuse;

2. The reuse of reclaimed water distributed to one-family or two-family dwellings. This prohibition does not apply to reuses of reclaimed water outside of and on the same property as one-family or two-family dwellings where the reclaimed water is not distributed to such reuses by way of plumbing within the dwellings;

3. The reuse of reclaimed water to fill residential swimming pools, hot tubs or wading pools;

4. The reuse of reclaimed water for food preparation or incorporation as an ingredient into food or beverage for human consumption;

5. Bypass of untreated or partially treated wastewater from the reclamation system or any intermediate unit process to the point of reuse unless the bypass complies with standards and requirements specified in 9VAC25-740-70 and is for essential maintenance to assure efficient operation;

6. The return of reclaimed water to the reclaimed water distribution system after the reclaimed water has been delivered to an end user; and

7. Reduction of the discharge from a VPDES permitted treatment works due to diversion of source water flow for reclamation and reuse such that the physical, chemical, or biological properties of the receiving state waters are affected in a manner that would cause a significant adverse impact to other beneficial uses.
