HAZARDOUS MATERIALS. Any material, including any substance, waste, or combination thereof, which, because of its quantity, concentration, or physical, chemical, or infectious characteristics may cause, or significantly contribute to, a substantial present or potential hazard to human health, safety, property, or the environment when improperly treated, stored, transported, disposed of, or otherwise managed.

Any unlawful disposal, placement, emptying, dumping, spillage, leakage, pumping, pouring, or other discharge of any substance other than stormwater into a stormwater conveyance system, the waters of the state, or upon the land such that the substance is likely to reach a stormwater conveyance system or waters of the state constitutes an ILLEGAL DISCHARGE, except as exempted in § 50.030.
ILLICIT CONNECTIONS. Either of the following:
(1) Any drain or conveyance, whether on the surface or subsurface, which allows an illegal discharge to enter the storm drain system, including, but not limited to, any conveyances which allow any non-stormwater discharge including sewage, process waste water, and wash water to enter the storm drain system and any connections to the storm drain system from indoor drains and sinks, regardless of whether said drain or connection had been previously allowed, permitted, or approved by a government agency; or
(2) Any drain or conveyance connected from a commercial or industrial land use to the storm drain system which has not been documented in plans, maps, or equivalent records and approved by the county.
IMPERVIOUS SURFACE. Any surface which, in whole or in part, restricts or prevents the natural absorption of water into the ground. Such surfaces may include, but not be limited to, compacted earth (such as marl and coquina), gravel, concrete, asphalt, or other paving material, and all area covered by the footprint of buildings or structures. Uncovered wooden slatted decks and the water area of a swimming pool are considered pervious.
INDUSTRIAL ACTIVITY. Activities subject to NPDES industrial permits as defined in 40 C.F.R. § 122.26(b)(14).
INTERMITTENT STREAMS. A natural drainage way, which shows up as a blue line on the USGS 7.5-minute quadrangle maps and has a contributing drainage area of 300 acres or less, shall be considered an INTERMITTENT STREAM for the purposes of this chapter.
LAND DISTURBING ACTIVITIES. The use of land by any person that results in a change in the natural cover or topography that may contribute to or alter the quantity and/or quality of stormwater runoff.
MAJOR SUBDIVISION. The division of a tract of land into six or more lots.
NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) STORMWATER DISCHARGE PERMITS. General, group, and individual stormwater discharge permits that regulate facilities defined in federal NPDES regulations pursuant to the Clean Water Act.
NATURAL DRAINAGE WAY. An incised channel with a defined channel bed and banks that are part of the natural topography. Construction channels such as drainage ditches shall not be considered a NATURAL DRAINAGE WAY unless the constructed channel was a natural drainage way that has been relocated, widened, or otherwise improved.
NON-STORMWATER DISCHARGE. Any discharge to the storm drain system that is not composed entirely of stormwater.
PERENNIAL STREAM. Streams that have essentially continuous flows and are shown on the United States Geological Survey 1:24,000 (7.5 min.) scale topographic maps. Streams that have a contributing drainage area of more than 300 acres shall be considered a PERENNIAL STREAM for the purposes of this chapter.
POLLUTANT. Anything, that causes or contributes to pollution. POLLUTANTS may include, but are not limited to: paints, varnishes, and solvents; oil and other automotive fluids; non-hazardous liquid and solid wastes and yard wastes; refuse, rubbish, garbage, litter, or other discarded or abandoned objects, articles, and accumulations, so that same may cause or contribute to pollution; floatables; pesticides, herbicides, and fertilizers; hazardous substances and wastes; untreated commercial car wash water and industrial discharges, contaminated fountain drains, and cooling waters; sewage, fecal coliform, and pathogens; dissolved and particulate metals; animal wastes; wastes and residues that result from constructing a building or structure (including, but not limited to, sediments, slurries, and concrete rinsates); and noxious or offensive matter of any kind.
