Final Rule: Mandatory Reporting of Greenhouse Gases
What Must Be Monitored for Each Adipic Acid Production Line?

                           Measure these parameters...
       Annual production rate (can be
       determined through sales records or by
       direct measurement using flow meters
       or weigh scales) (tons)
       Number of operating hours in the
       year (hours)
 Annual adipic acid production during
 which N2O abatement technology is
 operating (tons)

 Annual amount of process N2O
 emissions from adipic acid production
 sold or transferred off site (metric tons)
                     Annual Emission Factor Determination:

Facilities must conduct a performance test to calculate the process-specific emission factor either annually
or whenever the adipic acid production process is changed by altering the ratio of cyclohexanone to
cyclohexanol or by installing abatement equipment. The general procedure is as follows:
       Measure N2O emissions from the waste
       gas streams of each adipic acid
       oxidation process using test methods
       specified in the rule

       Measure the production rate during the
       test, and calculate the production rate
       for the test period in metric tons per
       hour
During the performance test the following must also be monitored:
Calculate a process-specific emission
factor for each adipic acid production line
as defined in subpart E of the rule
       N2O concentration per test run
       (parts per million N2O)
Volumetric flow rate of effluent gas
(dry standard cubic feet/hr)
       Production rate per test run
       (tons adipic acid produced/hour)

  If an N2O abatement technology is used, measure the following parameters:

  n   Annual adipic acid production during        Q  Destruction efficiency of N2O abatement
       which N2O abatement was used                 technology (abatement device destruction
                                                   efficiency, percent of N2O removed from
                                                   air stream)
  n   Total annual adipic acid production
       (tons acid produced)
