Section 501.360  Revised Universal Soil Loss Equation Version 2 (RUSLE2)

 

a)         The equation for calculating soil loss due to erosion is as follows:

 



 

Where:

 

ai	=	long-term average soils loss for the ith day;
riri	=	erosivity factor;
ki	=	soil erodibility factor;
li	=	soil length factor;
S	=	soil steepness factor;
ci	=	cover management factor; and
pi	=	supporting practices factor,
all on the ith day, except for slop steepness factor (S).

 

b)         The average annual soil loss is computed as follows:

 



 

Where:

 

A	=	average annual soil loss.
365m	=	number of days per year.
m	=	number of years in the analysis period.  The value for m is 1 for continuous vegetation on range, pasture, and other lands, where conditions are the same year after year, while m = the number of years of cropping management rotations on cropland and the number of years following a disturbance such as construction, logging, grading of a reclaimed surface mine, or closing of a land fill where conditions are changing year to year.

 

BOARD NOTE:  Soil loss may be calculated using Revised Universal Soil Loss Equation 2 (RUSLE2) software program available at http://fargo.nserl.purdue.edu/rusle2_dataweb/

Section 501.403  Protection of Livestock Management Facilities and Livestock Waste-Handling Facilities

 

a)         Existing livestock management facilities and livestock waste-handling facilities must have adequate diversion dikes, walls, or curbs that will prevent excessive outside surface waters from flowing through the animal feeding operation and will direct runoff to an appropriate disposal, holding, or storage area.  The diversions are required on all these structures unless there is negligible outside surface water that can flow through the facility or the runoff is tributary to an acceptable disposal area or a livestock waste-handling facility.  If inadequate diversions cause or threaten to cause a violation of the Act or applicable regulations, the Agency may require corrective measures.

 

b)         New livestock management facilities and livestock waste-handling facilities must have adequate diversions, dikes, walls, or curbs that will prevent excessive outside surface runoff waters from flowing through the animal feeding operation and will direct runoff to an appropriate disposal, holding, or storage area. The diversions are required on all these structures unless there is negligible outside surface water that can flow through the facility or the runoff is tributary to an acceptable disposal area or a livestock waste-handling facility.  A holding pond must be capable of storing a volume equal to or exceeding the animal feeding operation's area, plus any tributary area that is not part of the animal feeding operation (including roof area if tributary to the facility), multiplied by 12 inches for runoff from earthen areas or 15 inches for runoff from concrete areas unless the operator has justifiable reasons substantiating that a lesser storage volume is adequate. If inadequate storage volumes cause or threaten to cause a violation of the Act or applicable regulations, the Agency may require corrective measures. The storage volume of the containment facility must never be less than the 25-year 24-hour storm effluent guidelines as required by the new source performance standards of the U.S. Environmental Protection Agency in 40 CFR 412.

Section 501.404  Handling and Storage of Livestock Waste

 

a)         Any livestock waste stored for more than six months must be contained in a manure storage structure.

 

b)         Temporary Manure Stacks

 

1)         A temporary manure stack is a potential secondary source, as defined by the Act.  As a potential secondary source, a temporary manure stack is subject to the minimum setback zones established in Title IV of the Act.

 

2)         A temporary manure stack must not be located within 75 feet of any water well, except monitoring wells.

 

3)         A temporary manure stack must be constructed or established and maintained in a manner to prevent runoff and leachate from entering surface waters or groundwaters.  A cover and pad or other control must be provided to prevent runoff and leachate from entering surface waters and groundwater.

 

c)         Livestock Waste-Holding Facilities

 

1)         Liquid manure-holding tanks must be impermeable and capable of withstanding pressures and loadings to which those tanks may be subjected.

 

2)         Holding ponds and lagoons must be impermeable or so sealed as to prevent groundwater or surface water pollution.

 

3)         For livestock management facilities and livestock waste-handling facilities that are not required to obtain an NPDES permit, the contents of livestock waste-handling facilities must be kept at levels such that there is adequate storage capacity so that an overflow does not occur except in the case of precipitation exceeding a 25-year 24-hour storm.

 

4)         Liquid Livestock Waste

 

A)        Existing livestock management facilities that handle the waste in a liquid form must have adequate storage capacity in a liquid manure-holding tank, lagoon, holding pond, or any combination so as not to cause air or water pollution as defined in the Act or applicable regulations. If inadequate storage time causes or threatens to cause a violation of the Act or applicable regulations, the Agency may require that additional storage time be provided. In those cases, interim pollution prevention measures may be required by the Agency.

 

B)        New livestock waste-handling facilities that handle the waste in a liquid form must provide a minimum of 120-day storage with a liquid manure-holding tank, lagoon, holding pond, or any combination unless the operator has justifiable reasons substantiating that a lesser storage volume is adequate. If inadequate storage volumes cause or threaten to cause a violation of the Act or applicable regulations, the Agency may require corrective measures.

 

d)         Runoff Field Application Systems

Any livestock management facility not meeting the definition of a CAFO in Section 501.238 may construct and operate a runoff field application system for treating livestock waste from fewer than 300 animal units, complying with 35 Ill. Adm. Code 570, in lieu of utilizing liquid manure-holding tanks, holding ponds, or lagoons in compliance with subsection (c) or other livestock waste-handling systems that would assure compliance with the Act and this Subtitle E.

 

e)         Subsections (a) through (d) do not apply to livestock management facilities with fifty (50) or fewer animal units if the following conditions exist:

 

1)         The facility's location relative to the waters of the State is such that there is no discharge of livestock waste into the waters of the State, in violation of Section 12 of the Act;

 

2)         There is no discharge of livestock waste into the waters of the State through a human-made ditch, flushing system, or similar human-made device, in violation of Section 12 of the Act; and

 

3)         The facility is managed so that livestock waste is not allowed to accumulate to an extent that threatens to cause a discharge into the waters of the State, in violation of Section 12 of the Act.

Section 501.405  Field Application of Livestock Waste

 

a)         For livestock management facilities and livestock waste-handling facilities that are not required to obtain an NPDES permit, the quantity of livestock waste applied on soils must not exceed a practical limit as determined by soil type, especially its permeability, the soil condition (frozen or unfrozen), the percent slope of the land, cover mulch, proximity to surface waters and likelihood of reaching groundwater, and other relevant considerations.  These livestock waste application guidelines will be adopted under 35 Ill. Adm. Code 502.305, unless otherwise provided for by Board regulations. Facilities required to obtain an NPDES permit are subject to the requirements in 35 Ill. Adm. Code 502.Subpart F.  Unpermitted Large CAFOs claiming an agricultural stormwater exemption must comply with 35 Ill. Adm. Code 502.102 and the practices listed in Section 502.510(b) to qualify for the exemption.

 

b)         Operators of livestock waste-handling facilities must practice odor control methods during manure removal and field application so as not to affect a neighboring farm or non-farm residence or populated area by causing air pollution as described in Section 501.102(d). Odor control methods include:

 

1)         Soil injection or other methods of incorporation of waste into the soil, including disking or plowing;

 

2)         Consideration of climatic conditions, including wind direction and inversions;

 

3)         For liquid livestock waste:  whether supernatant used for irrigation purposes has been stored in a livestock waste lagoon system that complies with "Design of Anaerobic Lagoons for Animal Waste Management", as incorporated by reference at Section 501.200.

 

4)         Other methods as described in "Management of Manure Odor", as incorporated by reference at Section 501.200.
