Form 4-A Instructions: Manure Storage Descriptions and Dimensions
1. Use Form 4-A to describe the type of manure storage on your facility. Use a separate
form for each different manure storage (tank, lagoon, bedded pack, solid stack, etc.).
However, if you have two or more identical storages that are managed the same, consider
using a single form to describe them.
 Include a diagram and dimensions either in the space provided or attach to Form 4-A.
1. Describe how you operate this manure storage.
 Describe how often manure is removed and how.
 Identify existing collection and transfer equipment.
 Describe procedures and maintenance activities.
2. Certifications and registrations
 Check the appropriate boxes at the bottom of Form 4-A for all certifications and
registrations or permits you have for this manure storage.
 Mark the checkboxes to describe whether this manure storage takes runoff,
wastewater, rinse water or other material and from what source it comes. Example: A
pit beneath a gestation building receives manure from a shallow pit nursery.
 For more complex systems, consider producing a “management train” sketch. See the
example in Appendix B.
