Texas Administrative Code › Title 30 - ENVIRONMENTAL QUALITY › Part 1 - TEXAS COMMISSION ON ENVIRONMENTAL QUALITY › Chapter 210 - USE OF RECLAIMED WATER › Subchapter A - GENERAL PROVISIONS › Section 210.3 - Definitions

Current through Reg. 49, No. 28; July 12, 2024
The following words and terms when used in this chapter
					 shall have the following meanings unless the context clearly indicates
					 otherwise.
(1) Beneficial use--An
				  economic use of wastewater in accordance with the purposes, applicable
				  requirements, and quality criteria of this chapter, and which takes the place
				  of potable and/or raw water that could otherwise be needed from another source.
				  The use of reclaimed water in a quantity either less than or the economically
				  optimal amount may be considered a beneficial use as long as it does not
				  constitute a nuisance.
(2)
				  BOD5 --Five-day biochemical oxygen demand.
(3) CBOD5 --Five-day
				  carbonaceous biochemical oxygen demand.
(4) CFU--Colony forming units.
(5) Domestic wastewater--Waste and wastewater
				  from humans or household operations that are discharged to a wastewater
				  collection system or otherwise enters a treatment works. Also, this includes
				  waterborne human waste and waste from domestic activities such as washing,
				  bathing, and food preparation, including greywater and blackwater, that is
				  disposed in an on-site wastewater system as defined in Chapter 285 of this
				  title (relating to On-Site Wastewater Treatment).
(6) DRASTIC--A classification system for
				  comparing land units on the basis of their vulnerability to ground-water
				  pollution, a detailed description of which is found in Appendix 1 of this
				  chapter.

(7)
				  Edwards Aquifer--That portion of an arcuate belt of porous, water bearing,
				  predominantly carbonate rocks known as the Edwards and Associated Limestones in
				  the Balcones Fault Zone trending from west to east to northeast in Kinney,
				  Uvalde, Medina, Bexar, Comal, Hays, Travis, and Williamson counties; and
				  composed of the Salmon Peak Limestone, McKnight Formation, West Nueces
				  Formation, Devil's River Limestone, Person Formation, Kainer Formation, Edwards
				  Formation, and Georgetown Formation. The permeable aquifer units generally
				  overlie the less-permeable Glen Rose Formation to the south, overlie the
				  less-permeable Comanche Peak and Walnut formations north of the Colorado River,
				  and underlie the less-permeable Del Rio Clay regionally. (See Chapter 213 of
				  this title (relating to Edwards Aquifer).)
(8) Edwards Aquifer Recharge zone--Generally,
				  that area where the stratigraphic units constituting the Edwards Aquifer crop
				  out, and including the outcrops of other geologic formations in proximity to
				  the Edwards Aquifer, where caves, sinkholes, faults, fractures, or other
				  permeable features would create a potential for recharge of surface waters into
				  the Edwards Aquifer. The recharge zone is identified as that area designated as
				  such on official maps located in the offices of the commission and the Edwards
				  Underground Water District. (See Chapter 213 of this title (relating to Edwards
				  Aquifer).)
(9) Food crop--Any crops
				  intended for direct human consumption.
(10) Initial holding pond--An impoundment
				  which first receives reclaimed water from a producer at the quality levels
				  established by this chapter, not including subsequent holding ponds.
(11) Geometric mean--The nth root of the
				  product of all measurements made in a particular period of time, for example in
				  a month's time, where n equals the number of measurements made. In the
				  alternative, the geometric mean can also be computed as the antilogarithm of
				  the sum of the logarithm of each measurement made. Where any measurement using
				  either computation method equals zero, it must be substituted with the value of
				  one.
(12) l--Liter.
(13) Landscape impoundment--Body of reclaimed
				  water which is used for aesthetic enjoyment or which otherwise serves a
				  function not intended to include contact recreation.
(14) Leak detection system--A system or
				  device designed, constructed, maintained, and operated with a pond that is
				  capable of immediately detecting a release of leachate or reclaimed water that
				  migrates through a liner. The system may typically include a leachate
				  collection system along with either leak detection sensors or view
				  ports.
(15) Municipal
				  wastewater--Waste or wastewater discharged into a publicly owned or a privately
				  owned sewerage treatment works primarily consisting of domestic
				  waste.
(16) mg/l--Milligram per
				  liter.
(17) NTU--Nephelometric
				  turbidity units.
(18) Nuisance--Any
				  distribution, storage, or use of reclaimed water, in such concentration and of
				  such duration that is or may tend to be injurious to or which adversely affects
				  human health or welfare, animal life, vegetation, or property, or which
				  interferes with the normal use and enjoyment of animal life, vegetation, or
				  property.
(19) On-channel pond--An
				  impoundment wholly or partially within a definite channel of a stream in which
				  water flows within a defined bed and banks, originating from a definite source
				  or sources. The water may flow continuously or intermittently, and if
				  intermittently, with some degree of regularity, dependent on the
				  characteristics of the source or sources.
(20) Permit or permitted--A written document
				  issued by the commission or executive director in accordance with Chapter 305
				  of this title (relating to Consolidated Permits) which, by its conditions, may
				  authorize the permittee to construct, install, modify, or operate, in
				  accordance with stated limitations, a specified facility for waste discharge,
				  including a wastewater discharge permit.
(21) Pond system--Wastewater facility in
				  which primary treatment followed by stabilization ponds are used for secondary
				  treatment and in which the ponds have been designed and constructed in
				  accordance with applicable design criteria. (See Chapter 317 of this title
				  (relating to the Design Criteria for Sewerage Systems).)
(22) Producer--A person or entity that
				  produces reclaimed water by treating domestic wastewater or municipal
				  wastewater, in accordance with a permit or other authorization of the Agency,
				  to meet the quality criteria established in this chapter.
(23) Provider--A person or entity that
				  distributes reclaimed water to a user(s) of reclaimed water. For purposes of
				  this chapter, the reclaimed water provider may also be a reclaimed water
				  producer.
(24) Reclaimed
				  water--Domestic or municipal wastewater which has been treated to a quality
				  suitable for a beneficial use, pursuant to the provisions of this chapter and
				  other applicable rules and permits.
(25) Restricted landscaped area--Land which
				  has vegetative cover to which public access is controlled in some manner.
				  Access may be controlled by either legal means (e.g. state or city ordinance)
				  or controlled by some type of physical barrier (e.g., fence or wall). Example
				  of such areas are: golf courses; cemeteries; roadway rights-of-way; median
				  dividers.
(26) Restricted
				  recreational impoundment--Body of reclaimed water in which recreation is
				  limited to fishing, boating and other non-contract recreational
				  activities.
(27) Single grab
				  sample--An individual sample collected in less than 15 minutes.
(28) Spray irrigation--Application of finely
				  divided water droplets using artificial means.
(29) Subsequent holding pond--A pond or
				  impoundment which receives reclaimed water from an initial holding pond where
				  the quality of the water changes after management in the initial holding pond,
				  due to factors which may include:
(A) the
				  addition of water occurs such as contributions from surface water or ground
				  water sources, but not including contributions of reclaimed water, domestic
				  wastewater, or municipal wastewater;
(B) some type of utilization of the reclaimed
				  water for a beneficial use occurs; or
(C) commingling of reclaimed water with
				  surface water runoff where it occurs between storage in an initial holding pond
				  and the subsequent holding pond.
