7 Del. Admin. Code § 7103-163.0
"Agricultural land" means land cultivated for the production of crops or used for raising livestock.
"Agricultural utilization" means the application rate of wastes products which shall not exceed nutrient needs of the crop grown on the particular soil plus the other assimilative pathways in soils (e.g. immobilization with organic material, volatilization, and leachate in compliance with drinking water standards). The department may require a lower application rate if the design criteria for pathogens, metals or organics contained in these Regulations plus generally accepted technical standards for land treatment technology (e.g. U.S. EPA Process Design Manuals or Overcash, M.R. and P. Pal. 1979 Design of Land Treatment Systems for Industrial Wastes - Theory and Practice) cannot be achieved at the above application rate. This term may be used interchangeably with "agronomic rate".
"Agricultural wastes" means wastes normally associated with the production and processing of food and fiber on farms, feedlots, ranches, ranges and forests which may include animal manure, crop residues and dead animals; also agricultural chemicals, fertilizers and pesticides which may find their way into surface and subsurface and subsurface water.
"Collection" means any action involved in the gathering or subsequent placement of waste products into a vehicle, container or any other vessel for transportation to some other location.
"Crops for direct human consumption" means crops that are consumed by humans without processing to minimize pathogens before distribution to the consumer.
"Department" means the Department of Natural Resources and Environmental Control.
"Disposal" means the discharge, deposit, injection, dumping, spilling, leaking or placing of waste products on or in the land, the air or any waters, including ground water and includes any method of waste products utilization that involves reuse of nutrients in the waste product at greater than agronomic rates.
"Distribute" means to barter, sell, offer for sale, consign, furnish, provide or otherwise supply a material as part of a commercial enterprise or a giveaway program.
"Food chain crops" means tobacco, crops grown for human consumption and crops grown to feed animals whose products are consumed by humans.
"Handling" means any way in which waste products are dealt with, other than collection, burning, storage, treatment, land application, disposal or transportation. It includes distribution of waste products.
"Household waste" means waste derived from households (including single and multiple residences, hotels and motels, bunkhouses, ranger stations, crew quarters, campgrounds and day-use recreation areas) which is not sewage or septage.
"Impermeable" means having a hydraulic conductivity equal to or less than 1 x 10-7 cm/sec as determined by field and laboratory permeability tests made according to standard test methods which may be correlated with soil densification as determined by compaction tests.
"Label" means the display of all written, printed or graphic material on the immediate container or information accompanying the material.
"Land application" means the placement of waste products within 2 feet below the surface of land used to support vegetative growth.
"Land reclamation" means the application of waste products at a rate mot greater than necessary to support and maintain immediate revegetation. Application may be in multiple cycles prior to establishment of vegetation, but must be accomplished within a single short-term operational period.
"Land treatment" means a technology for t the intimate mixing or dispersion of wastes into the upper zone of the plant-soil system with the objective of microbial stabilization, immobilization, selective dispersion, or crop recovery loading to an environmentally acceptable assimilation of the waste.
"Liquid waste" means any waste which is not a solid waste as defined for the purposes of these regulations.
"Person" means an individual, trust, firm, joint stock company, federal agency, corporation (including a government corporation), partnership, association, state, municipality, commission, political subdivision of a state, or any interstate body.
"Solid waste" means any garbage, refuse, rubbish and other discarded materials resulting from industrial, commercial, mining, agricultural operations and from community activities which does a not contain free liquids. Containers holding free liquids shall be considered solid waste when the container is designed to hold free liquids for use other than storage (e.g. radiators, batteries, transformers) or the waste is household waste.
"Usable waste product" means an industrial waste that the Department has approved as a product or feedstock for a specified use.
