Rule 138.00.05-004 - Title 22 - Rules Governing the Arkansas Soil Nutrient and Poultry Litter Application and Management Program
Current through Register Vol. 49, No. 9, September, 2024
TITLE XXII RULES GOVERNING THE ARKANSAS SOIL NUTRIENT AND POULTRY LITTER APPLICATION AND MANAGEMENT PROGRAM
As used in this Title, the following terms shall have the definitions below unless otherwise specifically stated herein.
If any provision of this Title or the application thereof to any Person or circumstance is held invalid, such invalidity shall not affect other provisions or applications of this Title which can be given effect without the invalid provision or application, and to this end the provisions of this Title shall be considered severable.
Act 1061 of 2003 (codified at Ark. Code Ann. § 15-20-1104) declared the following areas to be Nutrient Surplus Areas:
1. Illinois River watershed: |
HUC 11110103 |
2. Spavinaw Creek watershed: |
HUC 11070209 |
3. Honey Creek watershed: |
HUC 11070206 |
4. Little Sugar Creek watershed: |
HUC 11070208 |
5. Upper Arkansas River watershed (which includes Lee Creek within Crawford and Creek within Sebastian County): Washington counties, and Massard |
HUC 11110104 |
6. Poteau River watershed: |
HUC 11110105 |
7. Mountain Fork of the Little River watershed: |
HUC 11140108 |
8. Upper White River watershed above its confluence with the Buffalo River: |
HUC 11010001 and HUC 11010003 ( excluding coverage under HUC 1101000308, 1101000309, 1101000310, and 110100031108). |
The Certified Nutrient Planner should incorporate additional Plan requirements as appropriate if required by incentive programs which apply to a specific owner or Operator.
If an owner or operator obtains a comprehensive nutrient management plan properly developed by the United States Department of Agriculture, the Arkansas Natural Resources Commission, or a Conservation District and based on the Arkansas Phosphorus Index, then he is not required to obtain a Nutrient Management Plan, a Poultry Litter Management Plan, or apply at the Protective Rate.
Upon the sale or transfer of Litter from a Poultry Feeding Operation within a Nutrient Surplus Area to any user, the Poultry Feeding Operation shall not be responsible for the use of the Litter by the purchaser or other transferee. Notwithstanding the foregoing, the Poultry Feeding Operation remains responsible for use of the Litter in compliance with this Title until actual possession of the Litter transfers to the purchaser or transferee and the Litter is removed from the Poultry Feeding Operation premises.
Any Person receiving Litter from a Poultry Feeding Operation within a Nutrient Surplus Area who intends to use the Litter for a purpose other than Land Application must use the Litter in a manner approved by the Commission. If the Person receiving the Litter intends to transfer the Litter to others, the Person must keep transfer records.
By law, a person who considers himself or herself injured in his or her person, business, or property by an executed Administrative Consent Order or a Commission order following a hearing has the right to appeal the case to District Court in his county of residence, the county where he does business, or in Pulaski County within thirty days of the decision. The executed Administrative Consent Order or Commission decision shall constitute final agency action for the purpose of judicial review. Judicial review of final agency action shall be as provided by the Arkansas Administrative Procedure Act, Ark. Code Ann. §§ 25-15-201 et. seq.

If a 1:10 ratio of Mehlich III extractant is used to conduct a soil test and the test results are given as pounds of Phosphorus per acre, multiply the P lbs/acre figures in the left-hand column of these tables by 1.3 to determine application rates.
If a 1:10 ratio of Mehlich III extractant is used to conduct a soil test and soil test results are given as parts per million, divide the P lbs/acre in the left-hand column of these tables by 2 (to obtain parts per million), then multiply that figure by 1.3 to determine application rates.
Table1 -Maximum poultry litter application rates allowed with the Arkansas Phosphorus Index for normal conditions (moderate runoff class, less than 1 ton erosion/acre, surface applied in spring, hayed & grazed). Alum-treated litter rates were calculated conservatively using 50% reduction in soluble P, rather than 75% reduction for the two ton rate. Values are in tons/acre.
