Virginia Administrative Code › Title 9 - ENVIRONMENT › Agency 25 - STATE WATER CONTROL BOARD › Chapter 740 - WATER RECLAMATION AND REUSE REGULATION › Part III - Application and Technical Requirements › Section 9VAC25-740-100 - Application for permit

Current through Register Vol. 40, No. 24, July 15, 2024
A. The need for
				  an owner to obtain a permit or modification or reissuance of an existing permit
				  from the department for a proposed or an existing reclamation system, reclaimed
				  water distribution system, satellite reclamation system (SRS), or, as
				  applicable, water reuse, shall be determined in accordance with
				  9VAC25-740-30.
				  Where required, permit coverage for these systems or activities shall be
				  provided in accordance with
				  9VAC25-740-40,
				  contingent upon receipt of a complete application from the owner. The
				  application shall contain supporting documentation and information required by
				  subsections B and C of this section.
B. General information. For projects that
				  involve water reclamation and the distribution of reclaimed water, the
				  following information shall be submitted with an application for a permit.
				  Information required for this subsection may be provided by referencing
				  specific information previously submitted to the department unless changes have
				  occurred that require the submission of new or more current information. For
				  projects that involve exclusively the distribution of reclaimed water,
				  information for only subdivisions 1, 2, and 5 of this subsection shall be
				  submitted with an application for a permit.
1.
				  A description of the design and a site plan showing operations and unit
				  processes of the proposed project, including and as applicable, treatment,
				  storage, distribution, reuse and disposal facilities, and reliability features
				  and controls. Treatment works, reclamation systems and reclaimed water
				  distribution systems previously permitted need not be included, unless they are
				  directly tied into the new units or are critical to the understanding of the
				  complete project. Design approaches shall be consistent with accepted
				  engineering practice and any applicable state regulations.
2. A general location map, showing
				  orientation of the project with reference to at least two geographic features
				  (e.g., numbered roads, named streams or rivers, etc.). A general location map
				  for a reclaimed water distribution system may be included in the map of a
				  service area required in accordance with subdivision C 1 a of this
				  section.
3. Information regarding
				  each wastewater treatment works that diverts or will divert source water to the
				  reclamation system to be permitted, including:
a. All unit processes used for the treatment
				  of wastewater at the facility prior to diversion to the reclamation
				  system;
b. Any SIUs that indirectly
				  discharge to the wastewater treatment works; and
c. Analyses of the source water to be
				  diverted by the facility to the reclamation system.
4. Information regarding the sewage
				  collection system that diverts or will divert sewage to the SRS to be
				  permitted, including:
a. The name of the
				  sewage collection system and the owner of that system;
b. Any SIUs that discharge directly or
				  indirectly to the collection line from which sewage will be diverted to the
				  SRS, excluding any downstream SIUs whose discharge has no potential to backflow
				  to the SRS intake. This information shall include the location of the SIUs and
				  distance between the SIUs and the SRS along the sewage collection line or
				  lines; and
c. Characterization of
				  the sewage to be diverted from the sewage collection system to the SRS at the
				  point of diversion. Analysis of the sewage may be required where SIUs described
				  in subdivision 4 b of this subsection discharge to the sewage collection
				  system.
5. Information
				  regarding each reclamation system or SRS to be permitted, including:
a. The standards specified in
				  9VAC25-740-70
				  A to be achieved;
b. Any other
				  physical, chemical, and biological characteristics and constituent
				  concentrations that may affect the intended reuse of the reclaimed water with
				  respect to adverse impacts to public health or the environment; and
c. Designated design flow.
6. For the purpose of determining
				  any significant adverse impacts to other beneficial uses, information regarding
				  the VPDES permitted wastewater treatment works or the sewage collection system
				  that will provide a new or increased diversion of source water to a reclamation
				  system or SRS for the production of reclaimed water and information, as
				  applicable, regarding the SRS that includes:
a. The latitude and longitude of the
				  treatment works discharge location to a surface water or the SRS return
				  discharge location in the sewage collection system;
b. The mean monthly discharge of the
				  treatment works or return discharge of the SRS for each month during the most
				  recent 60 or more consecutive months at the time of application, or where this
				  information is not available, estimated values for the mean monthly discharge
				  of the treatment works or return discharge of the SRS for each month during a
				  period of 12 consecutive months;
c.
				  The maximum monthly diversion of source water from the treatment works to a
				  reclamation system or from the sewage collection system to a SRS for each month
				  during a period of 12 consecutive months;
d. Pertaining only to sewage collection
				  systems that provide source water, the name of the treatment works at the
				  terminus of the sewage collection system; and
e. The information specified in subdivisions
				  6 a, b, and c of this subsection for each increase in source water diverted by
				  the treatment works or the sewage collection system to a reclamation system or
				  SRS, respectively, among multiple increases to occur in planned phases, and the
				  anticipated dates of the phased increases.
7. Information describing measures to be
				  immediately implemented for the management of wastewater and reclaimed water by
				  a conjunctive system in the event that primary reuses of reclaimed water
				  generated by the system cease or fail, and where the system:
a. Relies primarily or completely on water
				  reclamation and reuse to eliminate wastewater;
b. Relies on:
(1) Irrigation as the primary or only reuse
				  of reclaimed water, or
(2) One or
				  more large end users, each consuming a significant volume of reclaimed water,
				  such that the ability of the conjunctive system to manage wastewater would be
				  adversely impacted if any such end user were to discontinue receiving reclaimed
				  water from the conjunctive system; and
c. Does not have the ability to implement two
				  or more of the options described in
				  9VAC25-740-110 C
				  1.
8. Information
				  required per subdivision 7 of this subsection shall be included in the
				  reclaimed water management plan described in subsection C of this section where
				  the conjunctive system is acting as a reclaimed water agent by directly
				  distributing reclaimed water to an end user or end users, including an end user
				  that is also the applicant or permittee.
9. Information, if applicable, regarding any
				  type of proposed reuse not listed in this chapter, by which the department can
				  evaluate the need to prescribe specific reclaimed water treatment and
				  monitoring requirements in accordance with
				  9VAC25-740-90
