Burn Ban..anyway around it?

[Hebert]

I need to burn 5 acres of field so I can start my dirt work on it....I called the local fire dept to get permission to do it but they won't let me......but yet everyday I see fields being burnt around here....I know farmers are exempt from burn bans for agriculture purposes but it makes no sense that I cannot do the same on acreage that is completely disked around it with no house for atleast a quarter to half mile away...
are their any special permits I could buy? Is their anyway around this..other than straight out ignoring it and burning anyway? what are the penalty's/fines for burning now?
