98.246—Data reporting requirements.
In addition to the information required by § 98.3(c), each annual report must contain the information specified in paragraphs (a), (b), or (c) of this section, as appropriate for each process unit.
(a)
If you use the mass balance methodology in § 98.243(c), you must report the information specified in paragraphs (a)(1) through (a)(11) of this section for each type of petrochemical produced, reported by process unit.
(2)
The type of petrochemical produced, names of other products, and names of carbon-containing feedstocks.
(4)
Each of the monthly volume, mass, and carbon content values used in Equations X-1 through X-3 of this subpart (i.e., the directly measured values, substitute values, or the calculated values based on other measured data such as tank levels or gas composition) and the molecular weights for gaseous feedstocks and products used in Equation X-1 of this subpart, and the temperature (in °F) at which the gaseous feedstock and product volumes used in Equation X-1 of this subpart were determined. Indicate whether you used the alternative to sampling and analysis specified in § 98.243(c)(4).
(6)
Name of each method listed in § 98.244 used to determine a measured parameter (or description of manufacturer's recommended method).
(9)
If you comply with the alternative to sampling and analysis specified in § 98.243(c)(4), the amount of time during which off-specification product was produced, the volume or mass of off-specification product produced, and if applicable, the date of any process change that reduced the composition to less than 99.5 percent.
(10)
You may elect to report the flow and carbon content of wastewater, and you may elect to report the annual mass of carbon released in fugitive emissions and in process vents that are not controlled with a combustion device. These values may be estimated based on engineering analyses. These values are not to be used in the mass balance calculation.
(11)
If you determine carbon content or composition of a feedstock or product using a method under § 98.244(b)(4)(xv)(B), report the information listed in paragraphs (a)(11)(i) through (a)(11)(iv) of this section. Include the information in paragraph (a)(11)(i) of this section in each annual report. Include the information in paragraphs (a)(11)(ii) and (a)(11)(iii) of this section only in the first applicable annual report, and provide any changes to this information in subsequent annual reports.
(ii)
A copy of the method. If the method is a modification of a method listed in §§ 98.244(b)(4)(i) through (xiv), you may provide a copy of only the sections that differ from the listed method.
(iii)
An explanation of why an alternative to the methods listed in §§ 98.244(b)(4)(i) through (xii) is needed.
(b)
If you measure emissions in accordance with § 98.243(b), then you must report the information listed in paragraphs (b)(1) through (b)(8) of this section.
(1)
The petrochemical process unit ID or other appropriate descriptor, and the type of petrochemical produced.
(2)
For CEMS used on stacks for stationary combustion units, report the relevant information required under § 98.36 for the Tier 4 calculation methodology. Section 98.36(b)(9)(iii) does not apply for the purposes of this subpart.
(3)
For CEMS used on stacks that are not used for stationary combustion units, report the information required under § 98.36(e)(2)(vi).
(4)
The CO2 emissions from each stack and the combined CO2 emissions from all stacks (except flare stacks) that handle process vent emissions and emissions from stationary combustion units that burn process off-gas for the petrochemical process unit. For each stationary combustion unit (or group of combustion units monitored with a single CO2 CEMS) that burns petrochemical process off-gas, provide an estimate based on engineering judgment of the fraction of the total emissions that is attributable to combustion of off-gas from the petrochemical process unit.
(5)
For stationary combustion units that burn process off-gas from the petrochemical process unit, report the information related to CH4 and N2 O emissions as specified in paragraphs (b)(5)(i) through (b)(5)(iv) of this section.
(i)
The CH4 and N2 O emissions from each stack that is monitored with a CO2 CEMS, expressed in metric tons of each gas and in metric tons of CO2 e. For each stack provide an estimate based on engineering judgment of the fraction of the total emissions that is attributable to combustion of off-gas from the petrochemical process unit.
(ii)
The combined CH4 and N2 O emissions from all stationary combustion units, expressed in metric tons of each gas and in metric tons of CO2 e.
(iii)
The quantity of each type of fuel used in Equation C-8 in § 98.33(c) for each stationary combustion unit or group of units (as applicable) during the reporting year, expressed in short tons for solid fuels, gallons for liquid fuels, and scf for gaseous fuels.
(iv)
The HHV (either default or annual average from measured data) used in Equation C-8 in § 98.33(c) for each stationary combustion unit or group of combustion units (as applicable).
(6)
ID or other appropriate descriptor of each stationary combustion unit that burns process off-gas.
(7)
Information listed in § 98.256(e) of subpart Y of this part for each flare that burns process off-gas.
(c)
If you comply with the combustion methodology specified in § 98.243(d), you must report under this subpart the information listed in paragraphs (c)(1) through (c)(5) of this section.
(2)
For each stationary combustion unit that burns ethylene process off-gas (or group of stationary sources with a common pipe), except flares, the relevant information listed in § 98.36 for the applicable Tier methodology. For each stationary combustion unit or group of units (as applicable) that burns ethylene process off-gas, provide an estimate based on engineering judgment of the fraction of the total emissions that is attributable to combustion of off-gas from the ethylene process unit.
(3)
Information listed in § 98.256(e) of subpart Y of this part for each flare that burns ethylene process off-gas.
