# §98.146. 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)](#a) and [(b)](#b) of this section, as applicable.

- (a) If a CEMS is used to measure CO2 emissions, then you must report under this subpart the relevant information required under [§ 98.36](/cfr/40/98.36.md) for the Tier 4 Calculation Methodology and the following information specified in [paragraphs (a)(1) through (3)](#a-1..a-3) of this section:
  - (1) Annual quantity of each carbonate-based raw material (tons) charged to each continuous glass melting furnace and for all furnaces combined.
  - (2) Annual quantity of glass produced (tons), by glass type, from each continuous glass melting furnace and from all furnaces combined.
  - (3) Annual quantity (tons), by glass type, of recycled scrap glass (cullet) charged to each continuous glass melting furnace and for all furnaces combined.
- (b) If a CEMS is not used to determine CO2 emissions from continuous glass melting furnaces, and process CO2 emissions are calculated according to the procedures specified in [§ 98.143(b)](/cfr/40/98.143.md?p=b), then you must report the following information as specified in [paragraphs (b)(1) through (9)](#b-1..b-9) of this section:
  - (1) Annual process emissions of CO2 (metric tons) for each continuous glass melting furnace and for all furnaces combined.
  - (2) **Annual quantity of each carbonate-based raw material charged (tons) to all furnaces combined.**
  - (3) Annual quantity of glass produced (tons), by glass type, from each continuous glass melting furnace and from all furnaces combined.
  - (4) Annual quantity (tons), by glass type, of recycled scrap glass (cullet) charged to each continuous glass melting furnace and for all furnaces combined.
  - (5) Results of all tests, if applicable, used to verify the carbonate-based mineral mass fraction for each carbonate-based raw material charged to a continuous glass melting furnace, as specified in [paragraphs (b)(5)(i) through (iii)](#b-5-i..b-5-iii) of this section.
    - (i) **Date of test.**
    - (ii) **Method(s) and any variations used in the analyses.**
    - (iii) **Mass fraction of each sample analyzed.**
  - (6) [Reserved]
  - (7) Method used to determine decimal fraction of calcination, unless you used the default value of 1.0.
  - (8) **Total number of continuous glass melting furnaces.**
  - (9) The number of times in the reporting year that missing data procedures were followed to measure monthly quantities of carbonate-based raw materials, recycled scrap glass (cullet), or mass fraction of the carbonate-based minerals for any continuous glass melting furnace (months).
