Section 252:656-25-1 - The slow rate land application process

Slow rate land application is the controlled application of wastewater to the surface of land to achieve a designed degree of treatment through natural, chemical and biological processes that occur on and in the soil. In Oklahoma, slow rate land application systems are acceptable for meeting the agronomic water needs of pasture land, hay meadows and for crop production where the crops will not be eaten raw. See Appendix D for the loading rate, field area and storage volume equations. Refer to OAC 252:627 for permit and operations criteria.
