(3) "NPDES" means national pollutant discharge elimination system.
(4) "NPDES permit" means a permit issued by the state of Ohio pursuant to section 402 of the Federal Water Pollution Control Act and Chapter 6111. of the Revised Code and rules adopted thereunder.
(O) "Ohio EPA" means the Ohio environmental protection agency.
(1) "Person" means person, as defined in section 6111.01 of the Revised Code.
(2) "Permittee" means an NPDES permit holder.
(3) "Point source", for the purpose of this chapter, means any discernible, confined and discrete conveyance from a wastewater treatment works. This term does not include agricultural storm water discharges or return flows from irrigated agriculture.
(4) "Point source-point source trade" means a trade in which the person using water quality credits and the person generating water quality credits are both permittees.
(5) "Point source-nonpoint source trade" means a trade in which the person using water quality credits is a permittee and the person generating water quality credits is a nonpoint source.
(6) "Pollutant load" means the quantity of a pollutant expressed in units of mass or mass per unit time.
(7) "Pollutant specific-cap" means the sum of the wasteload allocations established under a TMDL for permittees participating in a point source-point source trade.
(8) "Pollution" means pollution as defined in section 6111.01 of the Revised Code.
(9) "Production area" means an AFO production area, as defined in 40 C.F.R. 122.23.
(1) "Qualified soil and water conservation professional" means county soil and water conservation district or "SWCD" staff, staff from the Ohio department of agriculture division of soil and water conservation or other Ohio department of agriculture staff, a natural resource conservation service or "NRCS" certified planner or an NRCS employee, a united states department of agriculture registered technical service provider or "TSP", a certified crop planner, a soil scientist as certified by the association of Ohio pedologists, a professional engineer, or equivalent professional as deemed by the director to have the education, knowledge and experience commensurate with this definition.
(2) "Quantified load reduction" means the reduction in a nonpoint source discharge that has been determined using one of the methods specified in this chapter.
(R) "Regional administrator" means the regional administrator of the appropriate regional office of the United States environmental protection agency or the authorized representative of the regional administrator.
(S) "Stewardship credit" means a water quality credit that is purchased and retired for the public benefit, rather than being used to meet an NPDES permit limit or other regulatory obligation.
(1) "Total maximum daily load" or "TMDL" means total maximum daily load, as defined in rule 3745-2-02 of the Administrative Code.
(2) "Trading ratio" means the mass of a pollutant that must be reduced to receive a water quality credit.
[Comment: A trading ratio of one to one or "1:1" means that one pound of a pollutant must be removed to receive a water quality credit for the reduction of one pound of that pollutant. A trading ratio of two to one or "2:1" means that two pounds of a pollutant must be removed to receive a water quality credit for the reduction of one pound of that pollutant.]
(1) "U.S. EPA" means the United States environmental protection agency.
(2) "Upstream trade" means a trade in which one source purchases water quality credits for pollutant reductions that are made by another source located upstream.
(1) "Wasteload allocation" means wasteload allocation, as defined in rule 3745-2-02 of the Administrative Code.
(2) "Water quality baseline" means the level of pollutant reduction that must be achieved before water quality credits can be generated.
(3) "Water quality credit" means the quantity of a pollutant that is available for a trade. Water quality credits are generated by pollutant reductions that are in excess of water quality baseline requirements, that occur within a specified period of time, and that are greater than those required by a regulatory requirement, such as an NPDES permit, or the wasteload allocation established under a TMDL.
(4) "Water quality standards" means the standards set forth in Chapter 3745-1 of the Administrative Code.
(5) "Water quality trade" means the purchase, sale, conveyance or other transfer of a water quality credit from one person or permittee to another person or permittee.
(6) "Water quality trading" or "trading" means a regulatory program that allows a permittee to meet its regulatory obligations by using pollutant reductions generated by another person.

(9) "Water quality trading management plan" means a management plan governing the operation and maintenance of water quality trading activities within a water quality trading area.
(10) "Watershed" means an area of land that drains to a common lake, pond, river, stream, or other waters of the state. A watershed may encompass a large river mainstem and all of its subbasins and tributaries when this is necessary to address regional or national water quality issues.
