In Nebraska, water reuse for water reuse for agricultureThe use of recycled water for production of both crops for human consumption and non-food crops of commercial value. This reuse application excludes consumption by livestock, onsite non-potable reuse, and landscaping. includes irrigation of crops that are not intended for distribution in their raw form for direct human consumption grown in areas with unrestricted public access. The source of water treated municipal wastewater Treated wastewater effluent discharged from a centralized wastewater treatment plant of any size. Other terms referring to this source of water include domestic wastewater, treated wastewater effluent, reclaimed water, and treated sewage. is specified by the state as domestic effluent. The write-up uses state terms when discussing sources or uses of water that may differ from the Regulations and End-Use Specifications Explorer's (REUSExplorer's) terms.
Technical basis
Nebraska approves the land application of treated domestic effluent at sites where agricultural crops will be grown and public access is unrestricted (119 Neb. Admin. Code, ch. 12). “Treated wastewater shall not be applied to crops that are intended for distribution in their raw form for direct human consumption (e.g., fresh produce)” and must be applied at an agronomic rate (119 Neb. Admin. Code, ch. 12). However, public access to the land application site shall be prohibited during the actual land application event (119 Neb. Admin. Code, ch. 12). All applicable provisions of the Clean Water Act (CWA) (33 U.S.C. §§ 1251 et seq.), including its implementing regulations, must be met in addition to any relevant rule requirements under the Food Safety Modernization Act (FSMA) (124 Stat. 3885). Treatment requirements and performance standards are applied for the removal of microbial contaminants, chemicals and other relevant indicators related to agriculture and are summarized in the table. The technical basis for developing the specifications and/or removals of microbial contaminants, chemicals and other relevant indicators is not explicitly specified.
Water reuse for agriculture approved for use in Nebraska
119 Neb. Admin. Code, ch. 12 defines the following approved water reuse for agriculture:
- Irrigation of crops that are not are intended for distribution in their raw form for direct human consumption (e.g., fresh produce) grown in areas with unrestricted public access
Water reuse treatment category for agriculture
The treatment requirements for treated domestic effluent are briefly summarized regarding water reuse for agriculture:
- Treated domestic effluent must be disinfected prior to land application in an unrestricted public access area at an agronomic rate. “If chlorine or a chlorine compound is used as the disinfection agent, the treated effluent must be dechlorinated prior to land application” (119 Neb. Admin. Code, ch. 12).
Additional context and definitions
“Unrestricted Public Access refers to areas where public access is not restricted” (119 Neb. Admin. Code, ch. 12). “Agronomic rate is defined as the application rate of nitrogen to meet the estimated nitrogen requirements of the crop being produced based on past or projected yields. In determining the agronomic rate, the permittee shall consider the nitrogen content of the wastewater, available nitrogen in the soil, and the amount of nitrogen from commercial fertilizer” (119 Neb. Admin. Code, ch. 12).
