option to dispose of the reclaimed water through a VPDES permitted discharge,
or
(2) There is an option to
dispose of the reclaimed water through a VPDES permitted discharge, but the
VPDES permit does not allow discharge of the full nutrient load under design
flow (e.g., a treatment works with a VPDES permitted discharge implements water
reclamation and reuse in lieu of providing treatment to meet nutrient effluent
limits at design flow).
5. A NMP required per subdivision 4 of this
subsection shall be approved by the Department of Conservation and Recreation
(DCR) and submitted with the RWM plan to the department. The applicant or

reliable treatment. This involves the use of treatment processes at both the
reclamation system and the waterworks that, in combination with any natural
attenuation provided by the environmental buffer to be described per
subdivision 3 c of this subsection, shall reliably achieve the water quality
necessary for IPR. A description of reclamation system treatment processes for
IPR may be satisfied by referencing application information submitted in
accordance with subsection B of this section.
c. Environmental buffers and natural
attenuation. This involves the use of an environmental buffer, such as a
surface water used as a WSS, to provide further removal or degradation of
certain contaminants when exposed to naturally occurring physical, chemical,
and biological processes in the environment over time.
d. Monitoring programs. This involves
monitoring at progressive stages of treatment or barriers of the project to
verify that they are working effectively and reliably to achieve the necessary
water quality for IPR.
e. Responses
to adverse conditions. To address those circumstances where the reclamation
system of the IPR project experiences a catastrophic treatment failure that
cannot be corrected by subsequent treatment or barriers, or fails to produce
reclaimed water meeting the standards or limits at the point of discharge to
the WSS, the application for the IPR project shall contain:
(1) A contingency plan that describes all
alternatives to be implemented in lieu of discharging the substandard reclaimed
water to the WSS.

2. All irrigation reuses of reclaimed water shall be limited to supplemental irrigation .
3. Nutrient management requirements for irrigation reuse will be established in the RWM plan according to the concentration of total N and total P in the reclaimed water compared to biological nutrient removal (BNR) as defined in 9VAC25-740-10.
a. Except as specified in subdivision 4 of this subsection, a nutrient management plan (NMP) shall not be required for irrigation reuse of reclaimed water treated to achieve BNR or nutrient levels below BNR .
b. For bulk irrigation reuse of reclaimed water not treated to achieve BNR , a NMP shall be required of the end user.
(1) Where the applicant or permittee is the end user , the NMP shall be submitted with the RWM plan to the department and shall be the responsibility of the applicant or permittee to properly implement.
(2) Where the end user is other than the applicant or permittee, the NMP shall be required as a condition of the service agreement or contract specified in subdivision 1 d of this subsection between the applicant or permittee and the end user . The end user shall be responsible for obtaining, maintaining and following a current NMP; providing a copy of the most current NMP to the applicant or permittee prior to initiating bulk irrigation reuse of reclaimed water; and providing proof of compliance with the NMP at the request of the permittee.
c. For nonbulk irrigation reuse of reclaimed water not treated to achieve BNR , a NMP shall not be required. However, the RWM plan shall describe other measures to be implemented by the applicant or permittee to manage nutrient loads by nonbulk irrigation reuse of reclaimed water not treated to achieve BNR within the service area. These shall include, but are not limited to the following:
(1) The inclusion of language in the service agreement or contract specified in subdivision 1 d of this subsection, explaining proper use of the reclaimed water by the end user for the purpose of managing nutrients;
(2) Routine distribution of literature not less than annually, to individual nonbulk irrigation end users addressing the proper use of reclaimed water for irrigation in accordance with 9VAC25-740-170 A; and
(3) Monthly monitoring of N and P loads by nonbulk irrigation reuses to the service area of the RWM plan based on the total monthly metered nonbulk irrigation reuse of reclaimed water for the service area and the monthly average concentrations of total N and total P in the reclaimed water. Results of this monitoring shall be included in the annual report to the department submitted in accordance with 9VAC25-740-200 C.
4. Independent of the reclaimed water nutrient content, a NMP shall be required for a bulk irrigation reuse site where:
a. A wastewater treatment works , reclamation system, SRS, or reclaimed water distribution system and the irrigation reuse site or sites are under common ownership or management; and
b. In addition to irrigation reuse:
(1) There is no option to dispose of the reclaimed water through a VPDES permitted discharge, or
(2) There is an option to dispose of the reclaimed water through a VPDES permitted discharge, but the VPDES permit does not allow discharge of the full nutrient load under design flow (e.g., a treatment works with a VPDES permitted discharge implements water reclamation and reuse in lieu of providing treatment to meet nutrient effluent limits at design flow ).
5. A NMP required per subdivision 4 of this subsection shall be approved by the Department of Conservation and Recreation (DCR) and submitted with the RWM plan to the department . The applicant or permittee shall be responsible for proper implementation of the NMP.
6. If required for a specific irrigation reuse, the NMP shall be prepared by a nutrient management planner certified by DCR and shall be maintained current in accordance with the Nutrient Management Training and Certification Regulations, 4VAC5-15. A copy of the NMP for each irrigation reuse site shall be maintained at the site or at a location central to all sites covered by the plan. Another copy shall be provided to and retained by the applicant or permittee.
7. A site plan is required for each bulk irrigation reuse site and area of proposed expansion to an existing irrigation reuse site, displayed on the most current U.S. Geological Survey topographic maps (7.5 minutes series, where available) and showing the following:
a. The boundaries of the irrigation site;
b. The location of all potable and nonpotable water supply wells and springs, public water supply intakes, occupied dwellings, property lines, areas accessible to the public, outdoor eating, drinking and bathing facilities; surface waters, including wetlands; limestone rock outcrops and sinkholes within 250 feet of the irrigation site; and
8. The site plan for a bulk irrigation reuse site shall be prepared by:
a. The applicant or permittee for submission with the RWM plan to the department when the irrigation site is under common ownership or management with a wastewater treatment works, a reclamation system, SRS, or reclaimed water distribution system from which it receives reclaimed water for irrigation; or
b. The bulk irrigation end user for submission with the service agreement or contract between the end user and the applicant or permittee when the irrigation site is not under common ownership or management with a wastewater treatment works, a reclamation system, SRS, or reclaimed water distribution system from which it receives reclaimed water for irrigation.
9. For the addition of new end users or new reuses not contained in the original RWM plan submitted with the application for a permit , the permittee shall submit to the department for approval an amendment to the RWM plan identifying the new end users or new reuses prior to connection and reclaimed water service to the new end users or initiating the new reuses. For each new end user or new reuse, the permittee shall also provide all applicable information required by this subsection. Amendment of the RWM plan for the addition of new end users or new reuses after the issuance or reissuance of the permit shall not be considered a modification of the permit unless the new end users or new reuses will require the addition of different reclaimed water standards, monitoring requirements and conditions not contained in the permit.
D. Indirect potable reuse (IPR). For an application to permit an IPR project, the following additional information shall be submitted by the applicant or permittee to the department :
1. Identification of the following components of an IPR project:
a. The reclamation system that will produce reclaimed water discharged to the water supply source (WSS).
b. The WSS to which the reclamation system identified in subdivision 1 a of this subsection will discharge reclaimed water .
c. The waterworks that will withdraw water from the WSS identified in subdivision 1 b of this subsection to produce potable water .
2. Identification of all uses in addition to IPR of the WSS identified in subdivision 1 of this subsection. Such uses shall be those deemed acceptable by the Virginia Department of Health or the Waterworks Regulations (12VAC5-590).
3. A description of multiple barriers to be implemented by the reclamation system or waterworks, or both, to produce water of a quality suitable for IPR . Multiple barriers shall include at a minimum:
a. Source control and protection. This involves the control of contaminants with potential to adversely impact public health by preventing or minimizing the entry of these contaminants into the wastewater collection system prior to reclamation or the WSS prior to withdrawal by the waterworks. Source control and protection shall, at a minimum, address pretreatment requirements for SIUs in accordance with 9VAC25-740-150 E and education requirements in accordance with 9VAC25-740-170 A 1, and shall describe other measures to reduce the introduction of contaminants from domestic sources that may include, but are not limited to, community collection programs for hazardous wastes and unused pharmaceuticals.
b. Effective and reliable treatment. This involves the use of treatment processes at both the reclamation system and the waterworks that, in combination with any natural attenuation provided by the environmental buffer to be described per subdivision 3 c of this subsection, shall reliably achieve the water quality necessary for IPR . A description of reclamation system treatment processes for IPR may be satisfied by referencing application information submitted in accordance with subsection B of this section.
c. Environmental buffers and natural attenuation. This involves the use of an environmental buffer, such as a surface water used as a WSS, to provide further removal or degradation of certain contaminants when exposed to naturally occurring physical, chemical, and biological processes in the environment over time.
d. Monitoring programs. This involves monitoring at progressive stages of treatment or barriers of the project to verify that they are working effectively and reliably to achieve the necessary water quality for IPR .
e. Responses to adverse conditions. To address those circumstances where the reclamation system of the IPR project experiences a catastrophic treatment failure that cannot be corrected by subsequent treatment or barriers, or fails to produce reclaimed water meeting the standards or limits at the point of discharge to the WSS, the application for the IPR project shall contain:
(1) A contingency plan that describes all alternatives to be implemented in lieu of discharging the substandard reclaimed water to the WSS.
(2) A notification program for the reclamation system of the IPR project as described in 9VAC25-740-170 A 2.
4. An evaluation of the combined effectiveness of all the barriers described in subdivision 3 of this subsection to achieve the water quality necessary for IPR .
5. Any information deemed necessary by the department to establish reclaimed water standards and monitoring requirements for the IPR project in accordance with 9VAC25-740-90 B. This shall include, but is not limited to, residence or transport times, mixing ratios, and other applicable modeling of the reclamation system discharge or contaminants introduced by the discharge to the WSS.
6. A water balance for the reclamation system that accounts for the volumes of reclaimed water to be generated, stored, discharged to the WSS, and withdrawn for IPR .
7. Any change by the reclamation system to provide reclaimed water for other reuses or end users in addition to IPR shall require submission of a RWM plan in accordance with subdivision C 1 of this section. The water balance for the RWM plan shall include the water balance required per subdivision 6 of this subsection for the IPR project.
8. A copy of the contractual agreement established between the reclamation system and the waterworks of the IPR project, identifying the responsibilities of each party to implement multiple barriers described in accordance with subdivision 3 of this subsection, unless the reclamation system and waterworks are under common ownership or management.
