The North Dakota Grain Growers Association will host the Environmental Protection Agency in an E-Tour across North Dakota this week. Tuesday the group will visit Berthold. Executive Director Dan Wogsland says the goal is to create a better understanding between the EPA and North Dakota agriculture. “We also want to get a better understanding of what the Environmental Protection Agency is looking at, some of the issues and some of the goals and responsibilities they have. It’s really a great two way street.” The tour wraps up Friday after a visit to the NDSU Research Center.
