CAT the Notice is the permit application. EVERYONE THEY FILED!!!! I hope that is clear. Also you do not hire an engineer to file a NOI. I have done plenty in my days and they are very straight forward. Just tell what you are going to do and how you will reclaim. There may be a need for archaeological work and wildlife if there are sensitive species in the area, but the BLM often does that if they are not over booked.
