Current through Register Vol. 40, No. 22, June 17, 2024

Section 9VAC25-610-102 - Evaluation of need for withdrawal and alternatives

A. The applicant shall identify the purpose of the proposed withdrawal by providing a narrative description of the water supply issues that form the basis of the proposed withdrawal.

B. The applicant shall subsequently demonstrate to the satisfaction of the department that the withdrawal meets an established water supply need.

1. In establishing local need for a public water supply, the applicant shall provide the following information:

a. Existing supply sources, yields and demands, including:

(1) Peak day and average daily withdrawal;

(2) Total consumptive use component of the withdrawal, including identification of the amount needed for human consumption;

(3) Types of water uses; and

(4) Existing water conservation measures and drought response plan, including what conditions trigger their implementation.

b. Projected demands in 10 year increments over a minimum 30-year planning period that includes the following:

(1) Projected demand contained in the local or regional water supply plan developed in accordance with 9VAC25-780 or for the project service area if such area is smaller than the planning area; or

(2) Statistical population (growth) trends, projected demands by use type including projected demand with and without water conservation measures.

2. In establishing need for agricultural water supply, the applicant shall provide the following information:

a. For crop irrigation: crop, acreage, crop spacing, crop watering requirements for the particular crop (crop rooting depth), soil types, soil holding capacity (available water capacity), allowable soil water depletion, historic precipitation records (precipitation contribution), peak irrigation months, irrigation scheduling approaches (tensiometers vs. feel method), irrigation type (drip, overhead, center pivot etc.), and irrigation system efficiency rating.

b. For livestock watering: kind and size of animal, rate and composition of gain, presence of pregnant animals or lactating animals, type of diet, level of dry matter intake, level of activity, quality of the water, temperature of the water offered, and surrounding air temperature.

3. In establishing need for commercial water supply, the applicant shall provide the following information:

a. Number of employees by month for an average year;

b. Average gallons per day used per month;

c. Average daily water use rate per employee per month; and

d. Identification of peak month of water demand.

4. In establishing need for industrial water supply, the applicant shall provide the following information:

a. SIC or NAICS industry code;

b. Number of employees by month for an average year;

c. Average gallons per day used per month;

d. Average daily water use rate per employee per month;

e. Identification of peak month of water demand;

f. Amount of withdrawal per unit of output or similar metric identified by the user; and

g. Monthly amount of water used for industrial processes.

C. The applicant shall provide an alternatives analysis that evaluates sources of water supply other than groundwater and the availability and use of lower qualities of groundwater that can still be put to beneficial use. For all proposed withdrawals, the applicant shall demonstrate to the satisfaction of the department:

1. Opportunities to reduce and minimize the use of groundwater have been identified and the requested amount is the minimum amount of groundwater necessary for the proposed activity;

2. The project utilizes the lowest quality water for the proposed activity;

3. Alternate sources of supply other than groundwater, including surface water and water reuse, were considered for use in the proposed activity particularly for consumptive use purposes; and

4. Practicable alternatives, including design alternatives, have been evaluated for the proposed activity. Measures that would avoid or result in less adverse impact to high quality groundwater shall be considered to the maximum extent practicable.

D. Any alternatives analysis conducted specifically for public water supply projects shall include:

1. All applicable alternatives contained in the local or regional water supply plan developed in accordance with 9VAC25-780;

2. Alternatives that are practicable that had not been identified in the local or regional water supply plan developed in accordance with 9VAC25-780;

3. Water conservation measures that could be considered as a means to reduce demand for each alternative considered by the applicant; and

4. A narrative description that outlines the opportunities and status of regionalization efforts undertaken by the applicant, including the interconnectivity of water systems and the ability for applicants to purchase water from other water supplies.

E. The alternatives analysis shall discuss the criteria used to evaluate each alternative including, but not limited to:

1. Demonstration that the proposed alternative meets the project purpose and project demonstrated need;

2. Availability of the alternative to the applicant;

3. Evaluation of interconnectivity of water supply systems and the ability to purchase water from other supplies when applicable (both existing and proposed); and

4. Evaluation of the cost of the alternative on an equivalent basis.
