    What about the massive effects it could have on the ConAgra processing plant that’s pretty much next door and its 600+ employees?

  2. Jay says:

    Who may we contact to offer quotes on valves too? We have received an inquiry and would to communicate directly with your company.

      Hi Jay,

      You’ll need to contact Magnida for that: – this website isn’t affiliated with them. I don’t think they’ve added a phone number yet, but the generic e-mail address they give is

      You could also try contacting the EPC contractor/s.

      Good luck,

      Hi Klaren,

      Sorry for the delay responding. The IDEQ Board met to decide the issue on November 20th, but continued that discussion today. So, the matter should be decided by now, but I haven’t yet heard their conclusion. The transcript of today’s meeting will be published, I’m told, by December 22nd.

      I haven’t heard any updates regarding financing. My guess would be that any further announcements will be on hold, pending the satisfactory resolution of the IDEQ hearings.

      All the best,
