This website publishes administrative rules on their effective dates, as designated by the adopting state agencies, colleges, and universities.

Rule 901:13-1-01 | General provisions.


(A) Purpose.

Chapter 901:13-1 of the Administrative Code applies to the control of pollutants from areas within the state used for agricultural production, including land being used for the production or keeping of animals or for the production of agricultural crops.

Chapter 901:13-1 of the Administrative Code establishes state standards for a level of management and conservation practices in farming and animal feeding operations on farms in order to abate excessive soil erosion or the pollution of waters of the state by soil sediment including pollutants attached to the sediment and animal manure. This chapter further define Ohio's pollution abatement grant program for landowners or operators to voluntarily install conservation practices.

The criteria in this chapter are intended for use in determining the acceptability of the level of management and conservation practices and for use by landowners and operators in planning, applying and maintaining appropriate management measures and conservation practices and to prevent the storage, handling, treatment, disposal, or land application of animal manure such that it is polluting or has a potential to pollute waters of the state contrary to these standards established by this chapter. Technical determinations by a district or the director shall be considered prima facie evidence of agricultural pollution.

(B) Definitions. As used in rules Chapter 901:13-1 of the Administrative Code:

(1) "Agricultural pollution" means failure to use management or conservation practices in farming operations to abate wind or water erosion of the soil or to abate the degradation of waters of the state by animal manure or soil sediment including substances attached thereto.

(3) "Agriculture animal" means any animal generally used for food or in agricultural production, including cattle, sheep, goats, rabbits, poultry, and swine; horses; alpacas; llamas; and any other animal included by the director of the Ohio department of agriculture by rule. "Agricultural animal" does not include fish or other aquatic animals regardless of whether they are raised at fish hatcheries, fish farms, or other facilities that raise aquatic animals.

(a) The wearing away of the land surface by running water, wind, ice or other geological agents, including such processes as gravitational creep.

(b) Detachment and movement of soil or rock fragments by water, wind, ice, or gravity.

(c) Erosion includes:

(i) "Gully erosion": the erosion process whereby water accumulates in narrow channels during and immediately after rainfall or snow or ice melt and actively removes the soil from this narrow area to considerable depths such that the channel would not be obliterated by normal smoothing or tillage operations.

(ii) "Rill erosion": an erosion process in which numerous small channels only several inches deep are formed; occurs mainly on recently disturbed soils. The small channels formed by rill erosion would be obliterated by normal smoothing or tillage operations.

(iii) "Sheet erosion": the removal of a fairly uniform layer of soil from the land surface by wind or runoff water.

(18) "Field Office Technical Guide" means the localized document used by the soil and water conservation district and developed (current edition) by the natural resources conservation service, United States department of agriculture, which is available to all Ohio county soil and water conservation districts, available at and which provides:

(a) Soil descriptions;

(b) Sound land use alternatives;

(c) Adequate conservation treatment alternatives;

(d) Standards and specifications of conservation practices;

(e) Conservation cost-return information;

(f) Practice maintenance requirements;

(g) Erosion prediction procedures.

(19) "Grassed waterway" means a natural course or constructed channel that is shaped or graded to required dimensions and established with suitable vegetation to filter and convey runoff from fields, terraces, diversions or other concentrated runoff without causing erosion or flooding.

(20) "Ground water" means any water below the surface of the earth in a zone of saturation, but does not include a perched water table.

(21) "Manure" means any of the following wastes used in or resulting from the production of agricultural animals or direct agricultural products such as milk or eggs: animal excreta, discarded products, process waste water, process generated waste water, waste feed, silage drainage, and compost products resulting from mortality composting, on farm biodigester operation residue that includes at least seventy-five per cent manure, or the composting of animal excreta.
