Odor and Nutrient Management Newsletter

Summer 2004


Correction to “Concrete solutions for confinement feeding operations” published in the Spring 2004 issue of ONM: The minimum concrete standards, adopted on March 24, 2004, are not required for the construction of a concrete pit or tank that is part of a small animal feeding operation (SAFO). These confinement feeding operations have an animal unit capacity of 500 animal units or less.

However, if a SAFO builds a concrete pit to replace an earthen basin or existing manure storage and handling facilities and the required separation distances from certain waters such as a wellhead, a water source or a sinkhole cannot be met, the SAFO must follow the minimum concrete standards unless secondary containment is provided. For a complete list of separated waters, see the Iowa Code Section 459.310.

The article “Implementing the phosphorus index for manure application” published in the Spring 2004 issue of ONM contained a table in which the column titles and numbers were misaligned. The corrected table has been posted to the Web version of the article.
