SCC Approves Proposing Rulemaking For Nutrient Management
M 3 .212. Identification of CAOs.
(a) A CAO Is an agricultural operation where the animal density exceeds two AEUs per acre on an annualized basis. In
order to datennine If a particular agricultural operation Is a CAO which is required to develop a nutrient management plan, the
number of AEUs per acre on the agricultural operation shall be calculated using the procedure set forth below.
(1) The number of AEUs on the agricultural operation shall be calculated by using the following steps:
(I) Multiply the average number of animals on the agricultural operation on a typical production day by the stan
datd animal weight contained In Table A to equal a total weight. Non-standard weights may be used In place ol those In Table
A prowled there is sufficient documentation to support the use of the non-standard weights.
C«) Multiply the total weight reached tn (I) (I) by the number of production days per year, then dhnde by 365 days,
(ill) Divide the number reached in (I) (II) by 1,000 to equal the number of AEUs for each type of animal.
(Kr) Total the number of AEUs for each type of animal to equal the total number of AEUs on the agricultural oper

(2) The number of AEUs per acre shall be calculated by dividing the total number of AEUs by the total number of acres
of land suitable for the application of manure to equal the number of AEUs per acre
(i) Land suitable, for the sole purpose of determining whether an agncultural operation is a CAO, is land in
the management control of the operator that meets all of the following catena
(A) The land is cropland, hayland, or pastureland that is an integral part of the agncultural operation, as
demonstrated by title, rental agreements, crop records, or form provided by the Commission
(B) The land is, or will be used, for the application of manure generated by the agncultural operation
(C) The land is located within 10 miles of the point of manure generation
(n) The term 'land su>table" shall not include farmstead areas or forest land
(b) Example AEU per acre calculation An operation has an average number of 10,000 medium broilers on a typical pro
duction day with an average weight dunng production of 2 3 pounds Dunng the year there are six (locks with a production
period of 43 days per flock This amounts to 258 production days per year Dunng the remaining down time no manure is pro
duced The farmstead is two acres There are three acres of woodlands and seven acres of cropland The following is the
AEU per acre calculation tor this operation
STEPI 10,000 med broilers x 23 lb avg wt =23,000 lb total weight
STEP 2 23,000 lb total weight x 258 production days per year divided by 365 days = 16,257 lbs
STEPS 16,257 lbs divided by 1000 lbs per AEU = 1625 AEUs
STEP 4 Total number of AEUs on the agricultural operation is 1625
STEP 5 16 25 AEUs divided by 7 acres of land suitable =23 AEUs per acre

1*3433. Determination of Nutrient Application FMee. j _
(a) Nitrogen shirt tie applied only in the amounts necessary to achieve realistic expected crop yields or at a rate not
exceeding what the crop will utlfee lor an Individual crop year. , . .
(b) The fyftffi planned manure application rate may be any rate equal to or leas than the balanced manure application
rate based on nitrogen. The balanced manure application rate baaed on nitrogen ahaH be determined by first subtracting me

amount ot nitrogen necessary for realistic expected yields and then dividing this by the available nitrogen content of the
manure as determined by standard methods a
(c) The plan shall include calculations demonstrating the difference between the recommended nitrogen necessary tor
realistic expected crop yields and any nitrogen added including, but not limited to, manure, sludge, starter fertilizer and other
fertilizer A deficit may be made up with supplemental nitrogen applications. A recommended nitrogen availability test may
also be used to determine supplemental nitrogen needs
