    If you are involved with Landfills, what are your plans for Pursuant to 40 CFR 60.27a(c)?  It requires greenhouse gas emissions to be lowered from 50 mg/yr to 34 mg/yr.
    These are the three options that I know of at the time.
    • Inject gas into our natural gas system

    Downside

    1. How it will react with a second gas source.
    2. The pipelines that will need to be installed. 
    3. The permits that will need to be obtained.
    • Load trucks for distributions to other locations

       

      • Send to Electric Grid through power generation from the flame

      Benefit

      1. No underground pipelines would have to be constructed.
      2. A 3 phase line currently exist at the flame for a direct tie into the grid.
      3. No permits would be required.

      Downside

      1.  Generators initial costs
      2.  Monthly maintenance cost
      3.  Maintenance technicians. 
      4.  Reconductoring the lines that feed the landfill
      5.  Adding protection and switching equipment to our system.
