D.2 An exception to the maximum 40% moisture content limit may be allowed during rainy periods, as defined in Rule 101, Definitions.

E Test Methods

The following test method shall be used to determine manure moisture content within occupied pens at the livestock feed yards.

shall be tested. Selection shall be random and must have at least four (4)

inches of manure base for the test to be valid. Boot covers shall be worn to help prevent transport of biological contaminants into the corrals.

E.2 Random samples shall be taken throughout each selected corral. The

m oisture content of manure shall be determined with an electrical conductivity moisture meter. Moisture reading shall be taken by introducing the probe three inches into the manure. All readings shall be recorded and averaged.

E.3 Random samples is defined for purposes of this rule as the moisture reading of occupied corrals in a manner lacking previous calculation, direction or without intent of a specific result or purpose.
