Sec. 3. (a) The owner/operator of a CFO shall have the results of a soil test prior to any land application events, as well as a manure test. Soil and manure tests must be conducted in accordance with the manure management plan that is submitted to the commissioner to meet the requirement in 327 IAC 19-7-1(c)(5).

(b) The application rate of nitrogen (N) must not exceed the N requirements based on the recommendations in the following documents for current or planned crops of the upcoming growing season as documented in the operating record:

1. (1) Purdue University Cooperative Extension Service publication ID-101: Animal Manure as a Plant Nutrient Resource, February 2001*.
2. (2) Tri-State Fertilizer Recommendations for Corn, Soybeans, Wheat and Alfalfa, Extension Bulletin E-2567 (New), July 1995**. Minimum N loss estimates must be used unless otherwise justified. This justification must be kept in the operating record.

(c) For the first manure application only, nutrient content of manure from facilities constructed after the effective date of this article must be:

1. (1) based on either:

   1. (A) manure test values as described in 327 IAC 19-7-5(d); or
   2. (B) values in the NRCS Agricultural Waste Management Field Handbook (AWMFH) Chapter 4, March 2008***; and
2. (2) applied at fifty percent (50%) of the rate listed in subsection (b).

For all subsequent manure application events, nutrient content values must be based on manure test values.

(d) As of the effective date of this article, the following must comply with the phosphorus application rates in Table 1:

1. (1) Large CAFOs, as defined in 40 CFR 122.23(b)****, that were approved for initial construction after February 13, 2003.
2. (2) CAFOs with a NPDES permit.

3. (3) CFOs approved for initial construction after the effective date of this article.

   Table 1
   Phosphorus Application Rates for Large CAFOs Approved for Initial Construction After February 13, 2003, and CFOs Approved for Initial Construction After the Effective Date of this Article
   Soil test level (ppm)	Application rate
   0-50	N based
   51-100	1.5 × P crop removal
   101-200	1.0 × P crop removal
   201+	0

(e) Beginning with the effective date of this article, CFOs and CAFOs not listed in subsection (d) must comply with the phosphorus application rates in Table 2:

(f) The following land application information must be added to the operating record as needed in accordance with required time frames established in this article and IC 13-18-10 and must be maintained and updated in the operating record:

1. (1) Expected crop yields.
2. (2) The date or dates manure, litter, or process wastewater is applied to each field.
3. (3) Precipitation events at the time of application and for twenty-four (24) hours prior to and following application.
4. (4) Test methods used to sample and analyze manure, litter, process wastewater, and soil.
5. (5) Results from manure, litter, process wastewater, and soil sampling.
6. (6) An explanation of the basis for determining manure, litter, and process wastewater application rates.
7. (7) Calculations showing the manure nitrogen and phosphorus to be applied to each field.
8. (8) Total amount of nitrogen and phosphorus actually applied to each field, including documentation of calculations for the total amount applied.
9. (9) The method used to apply the manure, litter, or process wastewater.
10. (10) The date or dates of manure, litter, and process wastewater application equipment inspection.
11. (11) USDA soil survey maps of currently available land application sites.
12. (12) The type of manure applied.
13. (13) A written conservation plan with an explanation of conservation practices used must be completed and implemented prior to land application on highly erodible land, if required in section 4(j) of this rule. CAFOs with a NPDES permit must have a nutrient management plan prior to land application on highly erodible land.
