It's important to understand that they are using a process against you in order to gain jurisdiction in this matter. Believe it or not, everything they've probably sent to you by virtue of notices, letters, etc. are all "offers of contract" . If those offers are not rejected within a certain amount of time, you've gone into "dishonor" and the "dispute" begins.
Also, it's critical to put the bureaucrat/gov't agent on official notice that he must establish his basis for intruding into your commercial affairs without your consent and this is big.....in order for his notice to have validity he must send it UNDER PENALTIES OF PERJURY (26 USC 6065) which they will NOT do because it leaves them personally liable. In Tx. some of the legal reform groups are stopping attorney's, code enforcers, etc. dead in their tracks because they understand the "adminstrative" rules and procedures used by the gov't at all levels to gain control over our affairs.
Politics enter when the BLM has to use a source of their aggregate in a residential area where they claim to the public we have to use this source as there are no others. Which is bull since they KNOW of this land but to save themselves money by using a source closer to where they need to use it. We are talking about a 1000 acre deposit which is 20 feet thick (as tested already), so there are many millions involved here and I am like some bug they just want to SQUASH !!!! at the time I was in my 6th year as Little League President and we built 2 baseball fields out of land donated by the govt so they certainly knew me and my positive intentions, many could have been employed here.
