Impervious surface means a surface that has been covered with a layer of material so that it is highly resistant to infiltration by water.
Impervious area means any surface that does not allow stormwater to infiltrate into the ground.
Impervious - means not allowing the passage of water through the surface of the ground or ground covering or a substantial reduction in the capacity for water to pass through the surface of the ground or ground covering.
Pervious surface means an area that releases as runoff a small portion of the precipitation that falls on it. Lawns, gardens, parks, forests or other similar vegetated areas are examples of surfaces that typically are pervious.
Regulated impervious surface means any of the following, alone or in combination:
Impervious cover means a surface composed of material that significantly impedes or prevents natural infiltration of water into soil.
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.
Massive Multiauthor Collaboration Site (or “MMC Site”) means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A “Massive Multiauthor Collaboration” (or “MMC”) contained in the site means any set of copyrightable works thus published on the MMC site.
Tank means an enclosed space which is formed by the permanent structure of a ship and which is designed for the carriage of liquid in bulk.
Potential geologic hazard area means an area that:
Infiltrative surface means designated interface where effluent moves from distribution media or a distribution product into treatment media or original soil. In standard trench or bed systems this will be the interface of the distribution media or product and in-situ soil. Two separate infiltrative surfaces will exist in a mound system and an unlined sand filter, one at the interface of the distribution media and fill sand, the other at the interface of the fill sand and in-situ soil.
Iatrogenic infertility means an impairment of fertility by surgery, radiation, chemotherapy, or other medical treatment affecting reproductive organs or processes.
Fish habitat means habitat which is used by any fish at any life stage at any time of the year, including potential habitat likely to be used by fish which could be recovered by restoration or management and includes off-channel habitat.
Antimicrobial hand or body cleaner or soap means a cleaner or soap which is designed to reduce the level of microorganisms on the skin through germicidal activity, and is regulated as an over-the-counter drug by the U.S. Food and Drug Administration. “Antimicrobial Hand or Body Cleaner or Soap” includes, but is not limited to, (A) antimicrobial hand or body washes/cleaners, (B) foodhandler hand washes, (C) healthcare personnel hand washes, (D) pre-operative skin preparations and (E) surgical scrubs. “Antimicrobial Hand or Body Cleaner or Soap” does not include prescription drug products, antiperspirants, “Astringent/Toner,” deodorant, “Facial Cleaner or Soap,” “General-use Hand or Body Cleaner or Soap,” “Hand Dishwashing Detergent” (including antimicrobial), “Heavy-duty Hand Cleaner or Soap,” “Medicated Astringent/Medicated Toner,” and “Rubbing Alcohol.”
Self-service storage facility or "facility" means any real property designed or used for the purpose of renting or leasing individual storage space to tenants who are to have access to that space for the purpose of storing and removing personal property.
stacked bicycle parking space means a horizontal bicycle parking space that is positioned above or below another bicycle parking space and equipped with a mechanical device providing floor level access to both bicycle parking spaces.
Underground tank means a device meeting the definition of tank whose entire surface area is totally below the surface of and covered by the ground.
Tandem parking means that two or more automobiles are parked on a driveway or in any other location on a lot, lined up behind one another.
Constructed wetlands means areas intentionally designed and created to emulate the water quality improvement function of wetlands for the primary purpose of removing pollutants from stormwater.
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.
Covered Species means the species for which the Bank has been established and for which Credits have been allocated as set forth in Exhibit F-1.
Potential electrical output capacity means, with regard to a unit, 33 per- cent of the maximum design heat input of the unit.
Loading or unloading means the handling of property:
Modular building manufacturer means a person or corporation who owns or operates a
Seepage pit means an excavation deeper than it is wide that receives septic tank effluent and from which the effluent seeps from a structural internal void into the surrounding soil through the bottom and openings in the side of the pit.
