Current through Register Vol. 41, No. 3, September 23, 2024
A. Surface water and groundwater conjunctive use systems for public water supplies.
1. Applicants proposing to withdraw
groundwater as part of a surface water and groundwater conjunctive use system
for public water supplies shall provide the following information to the
department in addition to information required by
9VAC25-610-90,
9VAC25-610-92,
or
9VAC25-610-94
as part of their permit application:
a. A
detailed description of the surface water and groundwater conjunctive use
system, including:
(1) Identification of all
surface water sources, including pond and reservoir volumes where
applicable;
(2) Identification of
the wells used on a continual basis to supplement surface water supply needs
and wells to be utilized in periods of reduced surface water availability. Well
construction information for all wells shall be submitted on the Water Well
Completion Report, Form GW2, which includes the following information:
(a) The depth of the well;
(b) The diameter, top and bottom, and
material of each cased interval;
(c) The diameter, top and bottom, for each
screened interval; and
(d) The
depth of pump intake.
(3) A description of the storage system,
excluding surface water sources described in subdivision 1 a (1) of this
subsection;
(4) A copy of the
Engineering Description Sheet developed by the Virginia Department of Health
for the withdrawal; and
(5) A line
drawing of the water supply system illustrating the water balance of the
system.
b. Records
documenting the amount of water withdrawn on a daily basis for each water
source during average weather conditions and during drought
conditions;
c. Documentation of the
seasonal supply of surface water during both average and drought
conditions;
d. Documentation of any
seasonal changes in demand that occur during an annual cycle of the specified
beneficial use or uses; and
e.
Other relevant information that may be required by the department to evaluate
the application.
2. The
applicant shall demonstrate that the groundwater withdrawal will originate from
the aquifer that contains the lowest quality water that will support the
proposed beneficial use or uses.
3.
The department shall evaluate the proposed groundwater withdrawal for
consistency with criteria specified in
9VAC25-610-110.
4. In addition to conditions established in
9VAC25-610-100,
9VAC25-610-110,
9VAC25-610-120,
9VAC25-610-130,
and
9VAC25-610-140,
the permit shall specify the maximum amount of groundwater that may be
withdrawn during the term of the permit and shall address variations in the
groundwater withdrawal amounts that may occur.
5. The department may issue any permit with
terms, conditions, or limitations necessary to protect the public welfare,
safety, and health, or to protect the resource.
6. Applicants may request approval to
withdraw groundwater amounts that exceed the withdrawal limits established in
subdivision 4 of this section from wells that are part of a conjunctive use
system to meet human consumption needs during periods of drought by applying
for a supplemental drought relief permit as described in
9VAC25-610-106.
B. Surface water and groundwater conjunctive use systems for uses other than public water supplies.
1. Applicants proposing to withdraw
groundwater as part of a surface water and groundwater conjunctive use system
for uses other than public water supplies shall provide the following
information to the department in addition to information required by
9VAC25-610-90,
9VAC25-610-92,
or

Completion Report, Form GW2, which includes the following information:
(a) The depth of the well;
(b) The diameter, top and bottom, and
material of each cased interval;
(c) The diameter, top and bottom, for each
screened interval; and
(d) The
depth of pump intake.
(3) A description of the storage system,
excluding surface water sources described in subdivision 1 a (1) of this
subsection; and
(4) A map
delineating the area in which the water will be beneficially used.
b. Records documenting the amount
of water withdrawn on a monthly basis and annual basis for each water source
during average weather conditions and during drought conditions;
c. Documentation of the seasonal supply of
surface water during both average and drought conditions;
d. Documentation of any seasonal changes in
demand that occur during an annual cycle of the specified beneficial use or
uses;
e. Other relevant information
that may be required by the department to evaluate the application.
2. The applicant shall demonstrate
that the groundwater withdrawal will originate from the aquifer that contains
the lowest quality water that will support the proposed beneficial use or
uses.
