I want to bring interrested parties up to date on the issue of replacing the  fuel mixers with carbuerators at  the Spraberry Plant.
It seems that this  replacement was performed ONLY as a fuel savings activity and that there  would be no increase in emissions or horsepower as a result.
According to  the TNRCC, they will allow this activity provided that the above is true and  that we prove that emissions and horsepower will not increase.
To do this  they have requested that we conduct an emissions test on one of the units  with the mixer on and then with the carbuerator on as a condition of their  approval.
IE before and after testing.
I am going to request that we be  allowed to do the testing with a portable emissions tester, which has been  verified in side by side testing on New Mexico units as opposed to bringing  in a third party referenced testing company.
Contractor testing runs about  $3-5,000.
A condition of all permitting issues is that the carbs are not supposed to be  installed on the units (preconstruction) until approval has been given by the  agency.
In this case, we will be allowed to install a carbuerator on the one  unit to be tested but not on all units.
Should testing show other  exceedances (emissions or Hp) in addition to fuel savings, this will trigger  actions requiring perimtting.
Under the circumstances, I think it would be  in the best interest of NNG to know for certain that we have not violated the  grandfather status of the units and that if our activity requires permitting,  we comply immediately.
I am sending out the letter request to the TNRCC today.
If approved, we  should test ASAP.
Remember, that sampling ports in the exhaust stack of the  unit to be tested will need to be constructed prior to testing.
Let me know  if the Team will need a diagram showing the sampling port locations.
