Persistent Pools - Enduring pools containing sufficient habitat to maintain significant aquaticlife uses.Person - An individual, corporation, organization, government, governmental subdivision oragency, business trust, estate, partnership, or any o<strong>the</strong>r legal entity or association.Pool - An area of <strong>the</strong> water column that has slow velocity and is deeper than a riffle, run, orglide. The water surface gradient of pools is very close to zero and <strong>the</strong>ir channel profile isusually concave. Pools often have eddies with varying directions of flow.Process <strong>Wastewater</strong> - Any water which, during manufacturing or processing, comes intodirect contact with or results from <strong>the</strong> production or use of any raw material, intermediateproduct, finished product, byproduct, or waste product.Publicly Owned Treatment Works (POTW) - Any devices and systems used in <strong>the</strong>storage, treatment, recycling, and reclamation of municipal sewage or industrial wastes of aliquid nature which is owned by <strong>the</strong> State or a municipality (and including certain politicalsubdivisions created by <strong>the</strong> State of Texas that provide regional municipal and industrialwastewater treatment). This definition includes sewers, pipes, and o<strong>the</strong>r conveyances only if<strong>the</strong>y convey wastewater to a POTW treatment plant. For a complete legal definition of POTW,see 40 CFR §403.3(q).RRadioactive Material - A naturally occurring or artificially produced solid, liquid, or gas thatemits radiation spontaneously.Renewal of <strong>Permit</strong> - An extension of <strong>the</strong> effective date of a permit that authorizes <strong>the</strong>continued discharge or disposal of wastewater without substantive changes in term, provision,requirement, or limiting parameters of a permit.Renewal of <strong>Permit</strong> With Changes (or Minor Amendment with Renewal) - Anextension of <strong>the</strong> effective date of a permit that authorizes <strong>the</strong> continued discharge or disposal ofwastewater without substantive changes in term, provision, requirement, or limiting parametersof a permit but with a change that would be considered a minor amendment if <strong>the</strong> applicant wasnot seeking to extend <strong>the</strong> expiration date of <strong>the</strong> permit.Riffle – A portion of <strong>the</strong> water column that is usually constricted where water velocity is fastdue to a change in surface gradient. Stream depth is generally shallow, and <strong>the</strong> channel profile isusually straight to convex. Surface flow through riffles usually ripples due to constriction,shallowness, and presence of irregular bottom substrates.Riparian Zone - Area that includes <strong>the</strong> stream bank and flood plain.Run – A portion of <strong>the</strong> water column that has rapid, non-turbulent, shore-to-shore flow. A runis too deep to be a riffle and its flow is too fast to be a pool. The channel profile under a run isusually a uniform flat plane.SSaltwater - A coastal water which has a measurable elevation change due to normal tides. In<strong>the</strong> absence of tidal information, saltwater is generally considered to be a coastal water whichtypically has a salinity of two parts per thousand or greater in a significant portion of <strong>the</strong> watercolumn.10411_10055-inst (7/14/2014) Instructions for <strong>Completing</strong> <strong>the</strong> <strong>Industrial</strong> <strong>Wastewater</strong> <strong>Application</strong> Page 10 of 124
