The MSA Forecast

Current Manure Setback Distance (for all forms of manure):

August

10 ft.

August 2019 - Dry weather provides a great opportunity to get manure applied. Setbacks are 10 feet while fields are dry. Look at the MSA map before every application. Check the MSA before applications, as weather events this time of year can surprise you. Irrigation water application can act just like a rain event. For help with irrigation, check out the Irrigation Scheduler tool from WSU: http://weather.wsu.edu/is/.

To prevent the risk of a runoff or leaching event, and maximize application timing, follow an Application Risk Management (ARM) plan. If you do not have an ARM plan, contact WCD today to request a field evaluation.

Keep an eye on the weather forecast for both rain events and flooding (https://www.nwrfc.noaa.gov/rfc/).

Caution needs to be taken when applying manure during high risk times. Heavy precipitation can move applied nutrients into the groundwater or off of your field and into nearby swales, ditches, and/or waterways. If this happens, you can be put under the CAFO permit.
