Applicant.Property owner or agent of a property owner who filed an application for a stormwater authorization under a TPDES general permit or an individual TPDES permit.
Authorized enforcement agency.Employees or designees of the mayor of the city or the state commission on environmental quality (“TCEQ”) have authority to enforce this article and/or the TPDES regulations.
Best management practices (“BMPs”).Schedule of activities, prohibitions of practices, maintenance procedures, structural controls, local ordinances, and other management practices to prevent or reduce the discharge of pollutants. BMPs also include treatment practices, operating procedures, and practices to control runoff, spills or leaks, waste disposal, or drainage from raw materials storage areas.
Building.Any structure, either temporary or permanent, with walls and a roof, designed to shelter a person, animal, or property, and occupying more than 100 square feet of area.
Construction activity.Includes soil disturbance, including clearing, grading, excavating, and other construction related activities (e.g., stockpiling of fill material and demolition); and does not include routine maintenance that is performed to maintain the original line and grade, hydraulic capacity, or original purpose of the site (e.g., the routine grading of existing dirt roads, asphalt overlays of existing roads, the routine clearing of existing rights-of-ways, and similar maintenance activities). Regulated construction activity is defined in terms of small and large construction activity.
(a) Small construction activity.Construction activity that results in land disturbances equal to or greater than one (1) acre and less than five (5) acres of land. Small construction activity also includes the disturbance of less than one (1) acre of total land area that is part of a larger common plan of development or sale if the larger common plan will ultimately disturb equal to or greater than one (1) and less than five (5) acres of land.
(b) Large construction activity.Construction activity that results in land disturbance of equal to or greater than five (5) acres of land. Large construction activity also includes the disturbance of less than five (5) acres of total land area that is part of a larger common plan of development or sale if the larger common plan will ultimately disturb equal to or greater than five acres of land.
Conveyance.Curbs, gutters, manmade channels and ditches, drains, pipes, and other constructed features designed or used for flood control or to otherwise transport stormwater runoff.
Hazardous materials.Any item or agent (biological, chemical, physical) that has the potential to cause harm to humans, animals, or the environment, either by itself or through interaction with other factors.
Illicit connection.Any man-made conveyance connecting an illicit discharge directly to the MS4.
Illicit discharge.Any discharge to a municipal separate storm sewer that is not entirely composed of stormwater, except discharges pursuant to a TPDES stormwater general permit or a separate authorization and discharges resulting from emergency firefighting activities.
Land disturbance activity.Any activity which changes the volume or discharge rate of stormwater runoff from the land surface. This includes grading, digging, cutting, scraping, or excavating of soil, placement of fill materials, paving, construction, substantial removal of vegetation, or any activity which bares soil or rock or involves the diversion or piping of any natural or manmade watercourse.
Maintenance agreement.A formal contract between the city and a property owner to guarantee long-term maintenance of stormwater management practices.
Permanent stormwater control measure.All practices and facilities employed to meet and maintain stormwater runoff quality and quantity requirements after site development has been completed.
Person.Any individual, association, organization, partnership, firm, corporation, or other entity recognized by law and acting as either the owner or as the owner’s agent.
Pollutant.In accordance with the Texas Water Code, section
26.001(13) a pollutant includes the following: dredged spoil, solid waste, incinerator residue, sewage, garbage, sewage sludge, filter backwash, munitions, chemical wastes, biological materials, radioactive materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt, and industrial, municipal, and agricultural waste discharged into any water in the state.
Premises.Any building, lot, parcel of land, or portion of land whether improved or unimproved including adjacent sidewalks and parking strips.
Stormwater management.The use of structural or nonstructural control practices/BMPs designed to reduce stormwater pollutant runoff, discharge volumes, peak flow discharge rates, and detrimental changes in stream temperature that affect water quality.
Stormwater pollution prevention plan (“SWP3”).A document that describes the BMPs and activities to be implemented by the permit holder to identify sources of pollution or contamination at a site and actions to eliminate or reduce pollutant discharges.
Surface water in the state.Lakes, bays, ponds, impounding reservoirs, springs, rivers, streams, creeks, estuaries, wetlands, marshes, inlets, canals, the Gulf of Mexico inside the territorial limits of the state (from the mean high water mark (“MHWM”) out 10.36 miles into the gulf), and all other bodies of surface water, natural or artificial, inland or coastal, fresh or salt, navigable or non-navigable, and including the beds and banks of all water-courses and bodies of surface water, that are wholly or partially inside or bordering the state or subject to the jurisdiction of the state; except that waters in treatment systems which are authorized by state or federal law, regulation, or permit, and which are created for the purpose of waste treatment are not considered to be water in the state.
Unauthorized discharge.Any direct or indirect non-stormwater discharge to the storm drain system except as exempted in section
29.02.005, prohibition of illicit connections, of this article.
