Exfiltration means any unauthorized release of data from within an information system. This includes copying the data through covert network channels or the copying of data to unauthorized media.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
Wastewater treatment plant means a facility designed and constructed to receive, treat, or store waterborne or liquid wastes.
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than 1 micrometer is rejected by an engineered barrier, primarily through a size-exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Filtration means a process for removing particulate matter from water by passage through porous media.
Water treatment plant means that portion of the water supply system which in some way alters the physical, chemical, or bacteriological quality of the water.
Transportation project means any project that the department is authorized by law to undertake including but not limited to a highway, tollway, bridge, mass transit, intelligent transportation system, traffic management, traveler information services, or any other project for transportation purposes.

Radiation therapy simulation system means a radiographic or fluoroscopic x-ray system intended for localizing the volume to be exposed during radiation therapy and confirming the position and size of the therapeutic irradiation field.
Wastewater System means a system of wastewater collection, treatment,
water meter means any apparatus for measuring or showing the volume of water supplied to, or of effluent discharged from any premises;
Public water supply system means a system for the provision to the public of piped water for human consumption, if the system has at least fifteen service connections or regularly serves at least twenty-five individuals. The term includes any source of water and any collection, treatment, storage, and distribution facilities under control of the operator of the system and used primarily in connection with the system, and any collection or pretreatment storage facilities not under such control which are used primarily in connection with the system.
Infiltration means water other than wastewater that enters a sewer system (including sewer system and foundation drains) from the ground through such means as defective pipes, pipe joints, connections, or manholes. Infiltration does not include, and is distinguished from, inflow.
Slow sand filtration means a process involving passage of raw water through a bed of sand at low velocity (generally less than 0.4 meters per hour) resulting in substantial particulate removal by physical and biological mechanisms.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
air transport means the carriage by aircraft of passengers, baggage, cargo, and mail, separately or in combination, held out to the public for remuneration or hire, including scheduled and non-scheduled air services;
Oxides of nitrogen means the sum of the volume mixing ratio (ppbv) of nitrogen monoxide (nitric oxide) and nitrogen dioxide expressed in units of mass concentration of nitrogen dioxide (µg/m3);
Air transportation means the public carriage by aircraft of passengers, baggage, cargo, and mail, separately or in combination, for remuneration or hire;
Refinery means a facility used to produce motor fuel from crude oil, unfinished oils, natural gas liquids, or other hydrocarbons and from which motor fuel may be removed by pipeline, by marine vessel, or at a rack.
Wastewater Treatment Works means an arrangement of devices and structures for treating wastewater, industrial wastes, and sludge. Sometimes used as synonymous with "waste treatment plant" or "wastewater treatment plant" or "pollution control plant".
Cannabis plant means any plant of the genus Cannabis;
Stormwater management planning area means the geographic area for which a stormwater management planning agency is authorized to prepare stormwater management plans, or a specific portion of that area identified in a stormwater management plan prepared by that agency.
Wastewater treatment tank means a tank that is designed to receive and treat an influent wastewater through physical, chemical, or biological methods.
Small municipal separate storm sewer system or "small MS4" means all separate storm sewers that are (i) owned or operated by the United States, a state, city, town, borough, county, parish, district, association, or other public body (created by or pursuant to state law) having jurisdiction over disposal of sewage, industrial wastes, stormwater, or other wastes, including special districts under state law such as a sewer district, flood control district or drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or a designated and approved management agency under § 208 of the CWA that discharges to surface waters and (ii) not defined as "large" or "medium" municipal separate storm sewer systems or designated under 4VAC50-60-380 A 1. This term includes systems similar to separate storm sewer systems in municipalities, such as systems at military bases, large hospital or prison complexes, and highway and other thoroughfares. The term does not include separate storm sewers in very discrete areas, such as individual buildings.
Pipelines means those pipelines within the Storage Facility that connect the Tanks to one another and to the receiving and delivery flanges of the Storage Facility.
