Chemigation

Chemigation is defined in the Chemigation Act as “any process whereby chemicals are applied to land or crops in or with water through an on-farm irrigation distribution system” (Title 195, Ch. 1, 003). The regulations apply whether the water is from a surface water source, such as a stream or canal, or groundwater from an irrigation well.

“Chemical” is any fertilizer or pesticide mixed with the water supply (Title 195, Ch. 1, 002). Note that insecticides, herbicides, and fungicides are all different forms of pesticide. The term fertilizer is limited to formulations or products used and formally recognized as plant nutrients. So, for the purposes of the Chemigation Act, livestock manure or waste products are not considered fertilizer. However, similar safety equipment is required for irrigation systems applying livestock wastes, as specified in Title 130 “Rules and Regulations Pertaining to Livestock Waste Control,” which is a separate permit program for livestock operations that is administered by the NDEE.

The manufacturer or seller of the pesticide should be able to provide you with a label for any pesticide you purchased. You can also go to the Nebraska Department of Agriculture’s website or call 1-402-471-2394 for additional information.

Title 195, Ch. 2, 002, specifies, “An application must be filed with the district for each injection location.” If you plan to inject chemicals for chemigation into the irrigation distribution pipeline at one location, say near the well, only one application is required. However, if you inject at each center pivot, an application must be filed for each injection location.

Generally not. These products alone do not typically meet the definition of a pesticide or fertilizer, so the use of these materials is, by definition, not considered chemigation. However, the Department encourages the use of safety equipment on an irrigation system when any material is injected into it or mixed with the irrigation water.

Yes. Chemigation at a nursery would be considered an “on farm”activity subject to the regulations.

Yes. The pesticide applicator’s license or card is completely separate from the chemigation applicator certification. One does not substitute for the other. The Nebraska Chemigation Act and the Title 195 regulations require that anyone operating a chemigation system must be certified as a chemigation applicator (Title 195, Ch. 1,001 and Chapter 13). In addition, any permit application must include the name of a certified chemigation applicator (Title 195, Ch. 2, 002).

You must attend a training session and pass a written test. To pass the test you must correctly answer at least 35 out of the 50 questions. UNL Cooperative Extension conducts the training and testing, so you should first contact your local County Extension Office for information about the nearest training and testing session and to obtain an application form and study materials.

A schedule of the applicator training and testing sessions is available on the UNL Northeast Extension Center’s website (go to http://nerec.unl.edu/calendar.htm then click on “Chemigation Training”) or the NDEE website. You might also contact your local county extension office as training and testing sessions are occasionally scheduled locally or on short notice and may not be included on either website listing.

Please allow six to eight weeks for processing and receipt of the chemigation application certification card in the mail from the NDEQ. If you did not pass the test, Cooperative Extension will notify you.

For a replacement card, please contact the Agriculture Section at NDEE at (402) 471-4239. Be sure to provide your full name and current address. Please note that you do not need to carry the chemigation applicator certification card as it simply helps to serve as a reminder. The list of certified chemigation applicators also is available on the NDEQ website along with the expiration date of their certification.

Please contact NDEE’s Agriculture Section by mail, by telephone at (877) 253-2603. Be ready to provide your name, address, and the date and location where you took the training and testing. If you have website access, you can also check the chemigation applicator list on the NDEE website to see if you are on the list. If your certification is current on the website list and you just haven’t received your card please let us know and a replacement card will be sent.

All chemigation applicator certifications expire on January 1 of the fourth year following the year issued (Neb. Rev. Stat. §46-1128).  A chemigation applicator certification card will be issued to successful applicants by the NDEE. The certification expires on January 1, 4 years after it is issued. For example, certifications issued in 2016 will expire on January 1, 2020. This information may also be found on the NDEE website.

You do not have to recertify before the certification expires. However, a current applicator certification is needed for any chemigation permit application. Applicators sometimes wait until after their certification has expired and then attend a training session early that same year. The Chemigation Act requires training and testing for initial or subsequent certification. Please be aware that there are a limited number of training and testing dates and locations and that most of the training sessions are held from January thru April, so don’t wait too long to attend a training and testing session.

No. The card simply serves as a reminder of your certification number and when your certification expires. The card is not required for anything else and when the NRD is checking the applicator information on your permit application they may simply check the NDEQ website listing. You can also check this information on the NDEE website.

Anyone that fails the test is normally notified by mail by the UNL Cooperative Extension and given information on the retest procedure, which can be done in the local Extension office. You may wish to attend another training session, but it is not required.

Yes. The Nebraska Environmental Protection Act makes it unlawful to cause pollution or place potential pollutants (i.e. fertilizers or pesticides)where they are likely to cause pollution (Neb. Rev. Stat. §81-1506). In addition, most pesticide labels prohibit application near or on surface water or wells. Contact the Nebraska Department of Agriculture’s Pesticide Program at (402) 471-2394 if you have questions about pesticide label and pesticide application restrictions.

Probably. Irrigation canals are, by definition, waters of the state so anyone connecting to an irrigation canal to supply a chemigation system is subject to the Chemigation Act. However, there is an exemption for limited situations involving open discharge systems (Title 195, Ch. 1, 001).

A list of certified irrigation pipeline check valves can be requested from the NDEQ’s Agriculture Section or you can go to the NDEE website.

An open discharge system is defined as “a system in which water is pumped or diverted directly into a ditch or canal in such a manner that the force of gravity at the point of discharge into the ditch or canal cannot cause water to flow back to the point from which the water is pumped or diverted” (Title 195, Ch. 1, 011). So, a closed pipe system would not be considered “open discharge”. Please note that there may also be other considerations related to potential groundwater pollution in high water table areas. If you have a question about this, please contact the NRD and NDEE to discuss whether or not your system would be considered an open discharge system before you attempt to use it for chemigation. Appropriate safety equipment is still recommended for open discharge systems and may still be required by the pesticide label.

Posting of a field is required when a restricted use pesticide or a chemical for which the label requires posting is used (Title 195, Chapter 12).

If you still wish to chemigate, you must first submit your permit application to the NRD and include the initial application fee. Since you missed the June 1 deadline, the NRD must handle your application as an initial or new one. The NRD is also required to inspect and approve the safety equipment before a permit can be issued (Title 195, Ch. 4, Sect. 003).

No. A permit for one injection location cannot be transferred or issued for another location (Title 195, Ch. 4, Sect. 004). A new permit would be needed.

The regulations provide for a “Special Permit” where the NRD determines by inspection that a chemigation system does not need all of the safety equipment specified in the regulations and the NDEQ concurs (Title 195, Ch. 5). Only a few special permits have been issued. Please contact your local NRD or the NDEQ if you would like further information on Special Permits or have a specific situation you would like to discuss.

No. Chemigation is defined as “any process whereby chemicals are applied to land or crops in or with water through an on-farm irrigation distribution system.” Application of chemicals to a residential lawn would not be “on-farm”. However, there are specific rules on backflow prevention for connections to a public drinking water supply system. So, if the lawn sprinkler system is connected to a public water supply system, please check with the water supplier or the Regulation & Licensure Division of the Nebraska Health and Human Services System- NHHS website. Contact the Health & Human Service at 402-471-0598 for more information. Even if a chemigation permit is not required and the lawn sprinkler system is on an individual well, we recommend that appropriate safety equipment is installed.

Yes, there may be requirements if the container capacity or use meets certain requirements spelled out in the Title 198 “Rules and Regulations Pertaining to Agricultural Chemical Containment.” For instance, if the pesticide or fertilizer container has a capacity of 500 gallons or more, requirements may exist for secondary containment (i.e. diking) as specified in the Title 198 regulations, even if the container is mobile or mounted on a trailer. Fertilizer containers up to 2,000 gallons in capacity have a seasonal exemption in most cases. However, please contact the NDEQ Agriculture Section at (402) 471-4239 with any questions, or go to the NDEQ website and click on the “NDEQ Programs” tab, then “Agriculture Programs,” “Agricultural Chemical Secondary Containment” for more information.
