The words and terms used in this chapter shall have the meanings defined in the State Water Control Law (§ 62.1-44.2 et seq. of the Code of Virginia) and the Permit Regulation (9VAC25-32) unless the context clearly indicates otherwise, except that for the purposes of this chapter:

"Agricultural stormwater discharge" means a precipitation-related discharge of manure, litter, or process wastewater that has been applied on land areas under the control of an animal feeding operation or under the control of an animal waste end-user in accordance with a nutrient management plan approved by the Virginia Department of Conservation and Recreation and in accordance with site specific nutrient management practices that ensure appropriate agricultural utilization of the nutrients in the manure, litter or process wastewater.

"Animal feeding operation" means a lot or facility where the following conditions are met:

1. Animals have been, are, or will be stabled or confined and fed or maintained for a total of 45 days or more in any 12-month period; and

2. Crops, vegetation, forage growth or post-harvest residues are not sustained in the normal growing season over any portion of the operation of the lot or facility.

Two or more animal feeding operations under common ownership are a single animal feeding operation for the purposes 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.

"Animal waste" means liquid, semi-solid, and solid animal manure and process wastewater, compost, or sludges associated with animal feeding operations including the final treated wastes generated by a digester or other manure treatment technologies.

"Animal waste end-user" or "end-user" means any recipient of transferred animal waste who stores or who utilizes the waste as fertilizer, fuel, feedstock, livestock feed, or other beneficial use for an operation under his control.

"Animal waste fact sheet" means the document that details the requirements regarding utilization, storage, and management of animal waste by end-users. The fact sheet is approved by the department.

"Beneficial use" means a use that is of benefit as a substitute for natural or commercial products and does not contribute to adverse effects on health or environment.

"Confined animal feeding operation," for the purposes of this regulation, has the same meaning as an "animal feeding operation."

"Department" means the Virginia Department of Environmental Quality.

"Director" means the Director of the Virginia Department of Environmental Quality or his designee.

"Nutrient management plan" or "NMP" means a plan developed or approved by the Department of Conservation and Recreation that requires proper storage, treatment, and management of animal waste and limits accumulation of excess nutrients in soils and leaching or discharge of nutrients into state waters; except that for an animal waste end-user who is not covered under the general permit, the requirements of 9VAC25-192-90 constitute the NMP.

"Organic source" means any nutrient source including, but not limited to, manures, biosolids, compost, and waste or sludges from animals, humans, or industrial processes, but for the purposes of this regulation it excludes waste from wildlife.

"Waste nutrient analysis rate" means a land application rate for animal waste approved by the board as specified in this regulation.

"Waste storage facility" means (i) a waste holding pond or tank used to store manure prior to land application, (ii) a lagoon or treatment facility used to digest or reduce the solids or nutrients, or (iii) a structure used to store manure or waste.

"Vegetated buffer" means a permanent strip of dense perennial vegetation established parallel to the contours of and perpendicular to the dominant slope of the field for the purposes of slowing water runoff, enhancing water infiltration, and minimizing the risk of any potential nutrients or pollutants from leaving the field and reaching surface waters.

"300 animal units" means 300,000 pounds of live animal weight, or the following numbers and types of animals:

a. 300 slaughter and feeder cattle;

b. 200 mature dairy cattle (whether milked or dry cows);
