As used in this chapter:
BEST MANAGEMENT PRACTICES OR BMPs: Means physical, structural, or managerial practices that, when used singly or in combination, prevent or reduce pollution of water and that have been approved by Lehi City. The relevant BMPs are more particularly defined in Lehi City's Guidance Document for Stormwater Management.
CITY: Means the City of Lehi or authorized designee.
CONSTRUCTION ACTIVITIES: Means activities as defined in the stormwater construction permit.
CONTAMINANT: Means any physical, chemical, biological, or radiological substance or matter in water.
DISCHARGE: Means dispose, deposit, spill, pour, inject, seep, dump, leak or place by any means, or that which is disposed, deposited, spilled, poured, injected, seeped, dumped, leaked, or placed by any means including any direct or indirect entry of any solid or liquid matter into the Municipal separate storm sewer system.
EASEMENT: Means an acquired privilege or right of use or enjoyment that a person, party, firm, corporation, municipality or other legal entity has in the land of another.
EROSION: Means the removal of soil particles by the action of water, wind, ice or other geological agents, whether naturally occurring or acting in conjunction with or promoted by anthropogenic activities or effects.
ILLICIT CONNECTIONS: Means illegal or unauthorized connections to the Municipal separate stormwater system whether or not such connections result in discharges into that system.
ILLICIT DISCHARGE: Means any discharge to the Municipal separate storm sewer system that is not composed entirely of stormwater and not specifically exempted under this chapter.
LOW IMPACT DEVELOPMENT (LID): Is an approach to land development or re-development that works with nature to more closely mimic pre-development hydrologic functions. LID employs principles such as preserving and recreating natural landscape features, minimizing effective imperviousness to create functional and appealing site drainage that treat stormwater as a resource rather than a waste product. There are many practices that have been used to adhere to these principals such as bio retention facilities, rain gardens, vegetated roof tops, rain barrels, and permeable pavements.
MS4 PERMIT: Means the general permit for discharges for Small Municipal Separate Storm Sewer Systems (MS4), permit latest version.
MAINTENANCE: Means any activity that is necessary to keep a stormwater facility in good working order so as to function as designed. Maintenance shall include complete reconstruction of a stormwater facility if reconstruction is needed in order to restore the facility to its original operational design parameters. Maintenance shall also include the correction of any problem on the site property that may directly impair the functions of the stormwater facility.
MAINTENANCE AGREEMENT: Means a document recorded in the land records that acts as a property deed restriction, and which provides for long-term maintenance of stormwater management practices.
MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4): Means the conveyances owned or operated by the City for the collection and transportation of stormwater, including the roads and streets and their drainage systems, catch basins, curbs, gutters, ditches, man-made channels, and storm drains.
NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM PERMIT OR NPDES PERMIT: Means a permit issued pursuant to 33 USC 1342.
NOTICE OF VIOLATION (NOV): Means a written notice of violation by the City to the responsible person, issued whenever the City finds that a person is in non-compliance with this chapter.

PRE-DEVELOPMENT: Means the status of an item prior to any modification, or in other words, native condition.
PROPERTY OWNER: Means landowner of property within the boundary of Lehi City.
QUALIFIED PERSON: Is a person knowledgeable in the principles and practice of erosion and sediment controls and pollution prevention, who possesses the skills to assess conditions at the construction site that could impact stormwater quality and the skills to assess the effectiveness of any stormwater controls selected and installed to meet the requirements of the Utah construction general permit.
RUNOFF: Means that portion of water or precipitation on a drainage area that is discharged from the area into the Municipal separate stormwater system.
SEDIMENT: Means solid material, both mineral and organic, that is in suspension, is being transported, or has been moved from its site of origin by air, water, gravity, or ice and has come to rest on the earth's surface.
SEDIMENTATION: Means soil particles suspended in stormwater that can settle in streambeds and disrupt the natural flow of the stream.
STORMWATER: Means stormwater runoff, snow melt runoff, surface runoff, street wash waters related to street cleaning or maintenance, infiltration and drainage.
STORMWATER CONSTRUCTION PERMIT: Means stormwater general permit for construction activities permit latest version as required by the Utah Department of Environmental Quality, Division of Water Quality.
STORMWATER MANAGEMENT: Means the programs to maintain quality and quantity of stormwater runoff to pre-development levels.
STORMWATER POLLUTION PREVENTION PLAN (SWPPP): Means the set of drawings and other documents that comprise all the information and specifications for the programs, drainage systems, structures, BMPs, concepts and techniques intended to maintain or restore quality and quantity of stormwater runoff to pre-development levels during and after construction.
STORMWATER RUNOFF: Means that portion of stormwater on a drainage area that is discharged from the area into the Municipal separate stormwater system.
STORMWATER UTILITY: Means the stormwater utility created by ordinance of the City to administer the stormwater management ordinance, and other stormwater rules and regulations adopted by the Municipality.
STRUCTURAL BMPs: Means devices that are constructed to provide control of stormwater runoff.
SURFACE WATER: Includes waters upon the surface of the earth in bounds created naturally or artificially including, but not limited to, streams, other watercourses, lakes and reservoirs.
UPDES: Means Utah Pollution Discharge Elimination System. (Ord. 99-2018, 11-13-2018)
