La. Admin. Code tit. 33 § VII-1002
Act-the Louisiana Environmental Quality Act (R.S. 30:2001 et seq).
Aquifer-a continuous geologic formation, group of formations, or part of a formation that contains enough saturated permeable materials to yield usable quantities of water to wells or springs. For the purposes of these regulations, a usable quantity of water is enough water to yield a groundwater sample within 24 hours after purging a monitoring well.
Contamination (Environmental)-the degradation of naturally occurring water, air, or soil quality either directly or indirectly as a result of human activities.
Contamination (Solid Waste)-the admixture of any solid waste with any amount of hazardous waste or any other type of waste not meeting the definition of solid waste.
Department-the Louisiana Department of Environmental Quality as created by R.S. 30:2001 et seq.
Liner-layer or layer(s) of materials beneath and on the sides of a solid waste disposal facility that are designed to restrict the escape of wastes or their constituents from the facility.
Major Modification-any change in a site, facility, process or disposal method, or operation that substantially deviates from the permit or tends to substantially increase the impact of the site, facility, process or disposal method, or operation on the environment.
Minor Modification-any modification that does not meet the criteria for a major modification.
Modification-any change in a site, facility, unit, process or disposal method, or operation that deviates from the specifications in the permit. Routine or emergency maintenance that does not cause the facility to deviate from the specifications of the permit is not considered a modification.
Monitoring Well-any permanent cased hole that is drilled, augured, bored, cored, driven, washed, dug, jetted, or otherwise constructed to obtain hydrologic and water quality data, which is usually installed at or near a known or potential source of groundwater contamination to satisfy regulatory requirements for groundwater monitoring at the regulated units.
Permit-a written authorization issued by the administrative authority to a person for the construction, installation, modification, operation, closure or post-closure of a certain facility used or intended to be used to process or dispose of solid waste in accordance with the Act, these regulations, and specified terms and conditions.
Person-an individual, trust, firm, joint stock company, corporation (including a government corporation), partnership, association, state, municipality, commission, political subdivision of the state, interstate body, or the federal government or any agency of the federal government.
Site-the physical location, including land area and appurtenances, of an existing or proposed storage, processing, or disposal facility. A site may consist of a number of facilities, each subject to a permit to process or dispose of solid waste.
Uppermost Aquifer-The geologic formation (excluding the vadose zone) nearest the natural ground surface that is an aquifer, as well as lower (deeper) geologic formations that are aquifers and are hydraulically connected within the facility's property boundary. An aquifer can yield usable quantities of groundwater and for the purposes of this regulation, an aquifer is defined as being capable of yielding a groundwater sample from a monitoring well within 24 hours without purging a monitoring well dry. The upper limit of the uppermost aquifer is measured at a point nearest to the natural ground surface to which the aquifer rises during the wet season.
