9VAC25-32-250: Animal feeding operations

A. All animal feeding operations shall maintain no point source discharge of pollutants to surface waters except in the case of a storm event greater than the 25-year, 24-hour storm. Animal feeding operations having 300 or more animal units utilizing a liquid manure collection and storage system or having 200 or more animal units of poultry are pollutant management activities subject to the VPA permit program. Two or more animal feeding operations under common ownership are a single animal feeding operation for the purpose of determining the number of animals at an operation if they adjoin each other or if they use a common area or system for the disposal of wastes.

B. Case-by-case determination.

1. The department may determine that any animal feeding operation that does not otherwise qualify for coverage under the VPA general permit and has not been required to obtain a VPDES permit be required to obtain an individual VPA permit upon determining that it is a potential or actual contributor of pollution to state waters. In making this determination the following factors shall be considered:

a. The size of the operation;

b. The location of the operation relative to state waters;

c. The means of conveyance of animal wastes and process waters into state waters;

d. The slope, vegetation, rainfall, and other factors affecting the likelihood or frequency of discharge of animal wastes and process waste waters into state waters;

e. The compliance history and the ability to make corrections in order to comply with the VPA general permit conditions;

f. The means of storage, treatment, or disposal of animal wastes; and

g. Other relevant factors.

2. A VPA permit application shall not be required for an animal feeding operation subject to subdivision 1 of this subsection until the department has conducted an on-site inspection of the operation and determined that the operation shall be regulated under the VPA permit program.
