# §98.56. Data reporting requirements.


In addition to the information required by [§ 98.3(c)](/cfr/40/98.3.md?p=c), each annual report must contain the information specified in [paragraphs (a) through (n)](#a..n) of this section at the facility level.

- (a) **Annual process N<I>2</I>O emissions from adipic acid production (metric tons).**
- (b) -(c) [Reserved]
- (d) Annual process N2O emissions from adipic acid production facility that is sold or transferred off site (metric tons).
- (e) **Number of abatement technologies (if applicable).**
- (f) **Types of abatement technologies used and date of installation for each (if applicable).**
- (g) **Abatement technology destruction efficiency for each abatement technology (percent destruction).**
- (h) Abatement utilization factor for each abatement technology (fraction of annual production that abatement technology is operating).
- (i) Number of times in the reporting year that missing data procedures were followed to measure adipic acid production (months).
- (j) If you conducted a performance test and calculated a site-specific emissions factor according to [§ 98.53(a)(1)](/cfr/40/98.53.md?p=a-1), each annual report must also contain the information specified in [paragraphs (j)(1) through (7)](#j-1..j-7) of this section for each adipic acid production unit.
  - (1) [Reserved]
  - (2) **Test method used for performance test.**
  - (3) [Reserved]
  - (4) **N<I>2</I>O concentration per test run during performance test (ppm N<I>2</I>O).**
  - (5) **Volumetric flow rate per test run during performance test (dscf/hr).**
  - (6) **Number of test runs.**
  - (7) **Number of times in the reporting year that a performance test had to be repeated (number).**
- (k) If you requested Administrator approval for an alternative method of determining N2O emissions under [§ 98.53(a)(2)](/cfr/40/98.53.md?p=a-2), each annual report must also contain the information specified in [paragraphs (k)(1) through (4)](#k-1..k-4) of this section for each adipic acid production facility.
  - (1) **Name of alternative method.**
  - (2) **Description of alternative method.**
  - (3) **Request date.**
  - (4) **Approval date.**
- (l) Fraction control factor for each abatement technology (percent of total emissions from the production unit that are sent to the abatement technology) if equation E-3c is used.
- (m) If only cyclohexane is oxidized to produce adipic acid and the quantity is known, report the information specified in [paragraph (m)(1)](#m-1) of this section. If materials other than cyclohexane are oxidized to produce adipic acid, report the information specified in [paragraph (m)(2)](#m-2) of this section.
  - (1) **Annual quantity of cyclohexane (tons) used to produce adipic acid.**
  - (2) **Annual quantity of cyclohexanone and cyclohexanol mixture (tons) used to produce adipic acid.**
- (n) **Annual percent N<I>2</I>O emission reduction for all production units combined.**
