(a)—(b) [Reserved]

(c) A company may increase or decrease its production allowances, including its Article 5 allowances, by trading with another Party to the Protocol according to the provision under this paragraph (c). A company may increase or decrease its essential-use allowances for CFCs for use in essential MDIs according to the provisions under this paragraph (c). A nation listed in appendix C to this subpart (Parties to the Montreal Protocol) must agree either to transfer to the person for the current control period some amount of production or import that the nation is permitted under the Montreal Protocol or to receive from the person for the current control period some amount of production or import that the person is permitted under this subpart. If the controlled substance is produced under the authority of production allowances and is to be sold in the United States or to another Party (not the Party from whom the allowances are received), the U.S. company must expend its consumption allowances allocated under §§ 82.6 and 82.7 in order to produce with the additional production allowances.

(1) For trades from a Party, the person must obtain from the principal diplomatic representative in that nation's embassy in the United States a signed document stating that the appropriate authority within that nation has established or revised production limits or essential-use allowance limits for the nation to equal the lesser of the maximum production that the nation is allowed under the Protocol minus the amount transferred, the maximum production or essential-use allowances that are allowed under the nation's applicable domestic law minus the amount transferred, or the average of the nation's actual national production level for the three years prior to the transfer minus the production transferred. The person must submit to the Administrator a transfer request that includes a true copy of this document and that sets forth the following:

(i) The identity and address of the person;

(ii) The identity of the Party;

(iii) The names and telephone numbers of contact persons for the person and for the Party;

(iv) The chemical type, type of allowance being transferred, and the level of allowances being transferred;

(v) The control period(s) to which the transfer applies; and

(vi) For increased production intended for export to the Party from whom the allowances would be received, a signed statement of intent to export to the Party.

(vii) In the case of transferring essential-use allowances, the transferor must include a signed document from the transferee identifying the CFC MDI products that will be produced using the essential-use allowances.

(2) For trades to a Party, a person must submit a transfer request that sets forth the following:

(i) The identity and address of the person;

(ii) The identity of the Party;

(iii) The names and telephone numbers of contact persons for the person and for the Party;

(iv) The chemical type, type of allowance being transferred, and the level of allowances being transferred; and

(v) The control period(s) to which the transfer applies.

(3) After receiving a transfer request that meets the requirements of paragraph (c)(2) of this section, the Administrator may, at his discretion, consider the following factors in deciding whether to approve such a transfer:

(i) Possible creation of economic hardship;

(ii) Possible effects on trade;

(iii) Potential environmental implications; and

(iv) The total amount of unexpended production or essential-use allowances held by a U.S. entity.

(v) In the case of transfer of essential-use allowances the Administrator may consider whether the CFCs will be used for production of essential MDIs.

(4) The Administrator will issue the person a notice either granting or deducting production allowances, Article 5 allowances, or essential-use allowances, and specifying the control period to which the transfer applies, provided that the request meets the requirement of paragraph (c)(1) of this sections for trades from Parties and paragraph (c)(2) of this section for trades to Parties, unless the Administrator has decided to disapprove the trade under paragraph (c)(3) of this section. For a trade from a Party, the Administrator will issue a notice that revises the allowances held by the person to equal the unexpended production, Article 5, or essential-use allowances held by the person under this subpart plus the level of allowable production transferred from the Party. For a trade to a Party, the Administrator will issue a notice that revises the production limit for the person to equal the lesser of:

(i) The unexpended production allowances, essential-use allowances, or Article 5 allowances held by the person under this subpart minus the amount transferred; or

(ii) The unexpended production allowances, essential-use allowances, or Article 5 allowances held by the person under this subpart minus the amount by which the United States average annual production of the controlled substance being traded for the three years prior to the transfer is less than the total production allowable for that substance under this subpart minus the amount transferred. The change in allowances will be effective on the date that the notice is issued.

(5) If after one person obtains approval for a trade of allowable production of a controlled substance to a Party, one or more other persons obtain approval for trades involving the same controlled substance and the same control period, the Administrator will issue notices revising the production limits for each of the other persons trading that controlled substance in that control period to equal the lesser of:

(i) The unexpended production allowances or Article 5 allowances held by the person under this subpart minus the amount transferred; or

(ii) The unexpended production allowances or Article 5 allowances held by the person under this subpart minus the amount by which the United States average annual production of the controlled substance being traded for the three years prior to the transfer is less than the total allowable production for that substance under this subpart multiplied by the amount transferred divided by the total amount transferred by all the other persons trading the same controlled substance in the same control period minus the amount transferred by that person.

(iii) The Administrator will also issue a notice revising the production limit for each person who previously obtained approval of a trade of that substance in that control period to equal the unexpended production allowances or unexpended Article 5 allowances held by the person under this subpart plus the amount by which the United States average annual production of the controlled substance being traded for the three years prior to the transfer is less than the total allowable production under this subpart multiplied by the amount transferred by that person divided by the amount transferred by all of the persons who have traded that controlled substance in that control period. The change in production allowances or Article 5 allowances will be effective on the date that the notice is issued.

(d) Effective January 1, 1996, there will be no trade in production or consumption allowances with other Parties to the Protocol for class I controlled substances, except for class I, Group VI, methyl bromide.

(e)—(f) [Reserved]

(g) International transfer of essential-use CFCs. (1) For trades of essential-use CFCs where the transferee or the transferor is a person in another nation (Party), the persons involved in the transfer must submit the information requested in § 82.12(d)(2) and (d)(3), along with a signed document from the principal diplomatic representative in the Party's embassy in the United States stating that the appropriate authority within that nation has approved the transfer of the essential-use CFCs.

(2) If the transfer claim is complete, and EPA does not object to the transfer, then EPA will issue letters to the transferor and the transferee indicating that the transfer may proceed. EPA reserves the right to disallow a transfer if the transfer request is incomplete, or if it has reason to believe that the transferee plans to produce MDIs that are not essential MDIs. If EPA objects to the transfer, EPA will issue letters to the transferor and transferee stating the basis for disallowing the transfer. The burden of proof is placed on the transferee to retain sufficient records to prove that the transferred essential-use CFCs are used only for production of essential MDIs. If EPA ultimately finds that the transferee did not use the essential-use CFCs for production of essential MDIs then the transferee is in violation of this subpart.

(H) The one percent offset applied to the unweighted amount traded will be deducted from the transferor's production or consumption allowance balance (except for trades from transformers and destroyers to producers or importers for the purpose of allowance reimbursement). In the case of transferring essential use allowances, the amount of one tenth of one percent of the amount traded will be deducted from the transferor's allowance balance. In the case of transferring critical use allowances, the amount of one tenth of one percent of the amount traded will be deducted from the transferor's critical use allowance balance.

(I) The transferor must include a signed document from the transferee identifying the CFC MDI products that will be produced using the essential-use allowances.

(ii) The Administrator will determine whether the records maintained by EPA, taking into account any previous transfers and any production, allowable imports and exports of controlled substances reported by the transferor, indicate that the transferor possesses, as of the date the transfer claim is processed, unexpended allowances sufficient to cover the transfer claim (i.e., the amount to be transferred plus, in the case of transferors of essential use allowances and critical use allowances, one tenth of one percent of the transferred amount). Within three working days of receiving a complete transfer claim, the Administrator will take action to notify the transferor and transferee as follows:

(A) If EPA's records show that the transferor has sufficient unexpended allowances to cover the transfer claim, the Administrator will issue a notice indicating that EPA does not object to the transfer and will reduce the transferor's balance of unexpended allowances by the amount to be transferred plus, in the case of transfers of production or consumption allowances, one percent of that amount, or in the case of transfers of essential use allowances, one tenth of one percent of that amount. When EPA issues a no objection notice, the transferor and the transferee may proceed with the transfer. However, if EPA ultimately finds that the transferor did not have sufficient unexpended allowances to cover the claim, the transferor and transferee will be held liable for any violations of the regulations of this subpart that occur as a result of, or in conjunction with, the improper transfer.

(B) If EPA's records show that the transferor has insufficient unexpended allowances to cover the transfer claim, or that the transferor has failed to respond to one or more Agency requests to supply information needed to make a determination, the Administrator will issue a notice disallowing the transfer. Within 10 working days after receipt of notification, either party may file a notice of appeal, with supporting reasons, with the Administrator. The Administrator may affirm or vacate the disallowance. If no appeal is taken by the tenth working day after notification, the disallowance shall be final on that day.

(iii) In the event that the Administrator does not respond to a transfer claim within the three working days specified in paragraph (a)(1)(ii) of this section the transferor and transferee may proceed with the transfer. EPA will reduce the transferor's balance of unexpended allowances by the amount to be transferred plus, in the case of transfers of production or consumption allowances, one percent of that amount, and in the case of essential use allowances and critical use allowances, one tenth of one percent of that amount. However if EPA ultimately finds that the transferor did not have sufficient unexpended allowances to cover the claim, the transferor and transferee will be held liable for any violations of the regulations of this subpart that occur as a result of, or in conjunction with, the improper transfer.

(b)—(c) [Reserved]

(d) Transfers of essential-use CFCs. (1) Effective January 1, 2002, any metered dose inhaler company (transferor) may transfer essential-use CFCs to another metered dose inhaler company (transferee) provided that the Administrator approves the transfer.

(2) The transferee must submit a transfer claim to the Administrator for approval before the transfer can take place. The transfer claim must set forth the following:

(i) The identities and addresses of the transferor and the transferee; and

(ii) The name and telephone numbers of contact persons for the transferor and the transferee; and

(iii) The amount of each controlled substance (CFC-11, CFC-12, or CFC-114) being transferred; and

(iv) The specific metered dose inhaler products (i.e. the MDI drug product or active moiety) that the transferee plans to produce with the transferred CFCs; and

(v) The country(ies) where the CFC metered dose inhalers produced with the transferred essential-use CFCs will be sold if other than in the United States; and

(vi) Certification that the essential-use CFCs will be used in the production of essential MDIs. If the MDIs are to be sold in the United States, the certification must state that MDIs produced with the transferred essential-use CFCs are listed as essential at 21 CFR 2.125, and were approved by the Food and Drug Administration before December 31, 2000. If the MDIs produced with the essential-use CFCs are to be sold outside the United States, the transferee must certify that the metered dose inhalers produced with the essential-use CFCs are considered essential by the importing country.

(3) The transferor must submit a letter stating that it concurs with the terms of the transfer as requested by the transferee.

(4) Once the transfer claim is complete, and if EPA does not object to the transfer, then EPA will issue letters to the transferor and the transferee within 10 business days indicating that the transfer may proceed. EPA reserves the right to disallow a transfer if the transfer request is incomplete, or if it has reason to believe that the transferee plans use the essential-use CFCs in anything other than essential MDIs. If EPA objects to the transfer, within EPA will issue letters to the transferor and transferee stating the basis for disallowing the transfer. The burden of proof is placed on the transferee to retain sufficient records to prove that the transferred essential-use CFCs are used only for production of essential MDIs. If EPA ultimately finds that the transferee did not use the essential-use CFCs for production of essential MDIs then the transferee is in violation of this subpart.

(G) For trades of consumption allowances, production allowances, export production allowances, or Article 5 allowances, the quantity of the 0.1 percent offset applied to the unweighted quantity traded that will be deducted from the transferor's allowance balance.

(ii) The Administrator will determine whether the records maintained by EPA indicate that the transferor possesses unexpended allowances sufficient to cover the transfer claim on the date the transfer claim is processed. The transfer claim is the quantity (in kilograms) to be transferred plus 0.1 percent of that quantity. The Administrator will take into account any previous transfers, any production, and allowable imports and exports of class II controlled substances reported by the transferor. Within three working days of receiving a complete transfer claim, the Administrator will take action to notify the transferor and transferee as follows:

(A) The Administrator will issue a notice indicating that EPA does not object to the transfer if EPA's records show that the transferor has sufficient unexpended allowances to cover the transfer claim. In the case of transfers of production or consumption allowances, EPA will reduce the transferor's balance of unexpended allowances by the quantity to be transferred plus 0.1 percent of that quantity. In the case of transfers of export production or Article 5 allowances, EPA will reduce the transferor's balance of unexpended allowances, respectively, by the quantity to be transferred plus 0.1 percent of that quantity. The transferor and the transferee may proceed with the transfer when EPA issues a no objection notice. However, if EPA ultimately finds that the transferor did not have sufficient unexpended allowances to cover the claim, the transferor and transferee, where applicable, will be held liable for any knowing violations of the regulations of this subpart that occur as a result of, or in conjunction with, the improper transfer.

(B) The Administrator will issue a notice disallowing the transfer if EPA's records show that the transferor has insufficient unexpended allowances to cover the transfer claim, or that the transferor has failed to respond to one or more Agency requests to supply information needed to make a determination. Either party may file a notice of appeal, with supporting reasons, with the Administrator within 10 working days after receipt of notification. The Administrator may affirm or vacate the disallowance. If no appeal is taken by the tenth working day after notification, the disallowance shall be final on that day.

(iii) The transferor and transferee may proceed with the transfer if the Administrator does not respond to a transfer claim within the three working days specified in paragraph (a)(1)(ii) of this section. In the case of transfers of production or consumption allowances, EPA will reduce the transferor's balance of unexpended allowances by the quantity to be transferred plus 0.1 percent of that quantity. In the case of transfers of export production allowances or Article 5 allowances, EPA will reduce the transferor's balance of unexpended allowances by the quantity to be transferred plus 0.1 percent of that quantity. If EPA ultimately finds that the transferor did not have sufficient unexpended allowances to cover the claim, the transferor and/or the transferee, where applicable, will be held liable for any knowing violations of the regulations of this subpart that occur as a result of, or in conjunction with, the improper transfer.

(b) Inter-pollutant transfers. (1) Effective January 1, 2003, a person (transferor) may convert consumption allowances, production allowances or Article 5 allowances for one class II controlled substance to the same type of allowance for another class II controlled substance listed in appendix B of this subpart, following the procedures described in paragraph (b)(3) of this section.

(i) A person (transferor) may only convert allowances for one class II controlled substance for which EPA has issued allowances under § 82.16 to another class II controlled substance for which EPA has issued allowances under § 82.16.

(ii) [Reserved]

(2) Inter-pollutant transfers will be permitted at any time during the control period and during the 30 days after the end of a control period.

(3) The transferor must submit to the Administrator a transfer claim that includes the following:

(i) The identity and address of the transferor;

(ii) The name and telephone number of a contact person for the transferor;

(iii) The type of allowances being converted, including the names of the class II controlled substances for which allowances are to be converted;

(iv) The quantity (in kilograms) and type of allowances to be converted;

(v) The quantity (in kilograms) of allowances to be subtracted from the transferor's unexpended allowances for the first class II controlled substance, to be equal to 100.1 percent of the quantity of allowances converted;

(vi) The quantity (in kilograms) of allowances to be added to the transferee's unexpended allowances for the second class II controlled substance, to be equal to the quantity (in kilograms) of allowances for the first class II controlled substance being converted multiplied by the quotient of the ozone depletion potential of the first class II controlled substance divided by the ozone depletion potential of the second class II controlled substance, as listed in Appendix B to this subpart;

(vii) The control period(s) for which the allowances are being converted; and

(viii) The quantity (in kilograms) of unexpended allowances of the type and for the control period being converted that the transferor holds under authority of this subpart as of the date the claim is submitted to EPA.

(4) The Administrator will determine whether the records maintained by EPA indicate that the convertor possesses unexpended allowances sufficient to cover the transfer claim on the date the transfer claim is processed (i.e., the quantity (in kilograms) to be converted plus 0.1 percent of that quantity (in kilograms)). EPA will take into account any previous transfers, and any production, imports (not including transshipments or used class II controlled substances), or exports (not including transhipments or used class II controlled substances) of class II controlled substances reported by the convertor. Within three working days of receiving a complete transfer claim, the Administrator will take action to notify the convertor as follows:

(i) The Administrator will issue a notice indicating that EPA does not object to the transfer if EPA's records show that the convertor has sufficient unexpended allowances to cover the transfer claim. EPA will reduce the transferor's balance of unexpended allowances by the quantity to be converted plus 0.1 percent of that quantity (in kilograms). When EPA issues a no objection notice, the transferor may proceed with the transfer. However, if EPA ultimately finds that the transferor did not have sufficient unexpended allowances to cover the claim, the transferor will be held liable for any violations of the regulations of this subpart that occur as a result of, or in conjunction with, the improper transfer.

(ii) The Administrator will issue a notice disallowing the transfer if EPA's records show that the transferor has insufficient unexpended allowances to cover the transfer claim, or that the transferor has failed to respond to one or more Agency requests to supply information needed to make a determination. The transferor may file a notice of appeal, with supporting reasons, with the Administrator within 10 working days after receipt of notification. The Administrator may affirm or vacate the disallowance. If no appeal is taken by the tenth working day after notification, the disallowance shall be final on that day.

(iii) The transferor may proceed with the transfer if the Administrator does not respond to a transfer claim within the three working days specified in paragraph (b)(4) of this section. EPA will reduce the transferor's balance of unexpended allowances by the quantity (in kilograms) to be converted plus 0.1 percent of that quantity (in kilograms). The transferor will be held liable for any violations of the regulations of this subpart that occur as a result of, or in conjunction with, the improper transfer if EPA ultimately finds that the transferor did not have sufficient unexpended allowances or credits to cover the claim.

(c) Inter-company transfers and Inter-pollutant transfers. If a person requests an inter-company transfer and an inter-pollutant transfer simultaneously, the quantity (in kilograms) subtracted from the transferor's unexpended production or consumption allowances for the first class II controlled substance will be equal to 100.1 percent of the quantity (in kilograms) of allowances that are being converted and transferred.

(d) Permanent transfers. The procedures in paragraph (a) of this section apply to permanent inter-company transfers of baseline production allowances or baseline consumption allowances. A person receiving a permanent transfer of baseline production allowances or baseline consumption allowances (the transferee) for a specific class II controlled substance will be the person who has their baseline allowances adjusted in accordance with phaseout schedules in this subpart. No person may conduct permanent inter-pollutant transfers of baseline production allowances or baseline consumption allowances.

[68 FR 2848, Jan. 21, 2003, as amended at 71 FR 41172, July 20, 2006; 81 FR 6768, Feb. 9, 2016; 85 FR 15298, Mar. 17, 2020; 89 FR 82432, Oct. 10, 2024]

(a) Source applicability. The requirements specified in this section apply to every entity which engages in any of the following activities:

(1) Use of a controlled substance as a process agent.

(2) [Reserved]

(b) Emissions of controlled substances to report. Every entity that engages in any activity listed in paragraph (a) of this section must report, for each applicable facility, emissions of the controlled substances in paragraph (b)(1) of this section from the processes listed in paragraph (b)(2) of this section.

(1) Emissions of controlled substances. For purposes of reporting emissions under this section, the term “controlled substance” applies to the following controlled substances:

(i) Each controlled substance used as a process agent.

(ii) [Reserved]

(2) Processes. For purposes of this section, the term “process” applies to the following activities:

(i) Each activity listed in paragraph (a) of this section;

(ii) Each separation process for the reuse or recycling of the controlled substance;

(iii) Each transformation process of the controlled substance, where the controlled substance is produced at the facility and used in processes resulting in its transformation at the same facility;

(iv) Each transformation process of the controlled substance at the facility, where one or more of the controlled substances transformed at the facility is produced at another facility; and

(v) Each destruction process of the controlled substance.

(c) Calculating emissions for controlled substances. For every activity listed in paragraph (a) of this section, each entity must calculate emissions of the controlled substances from each process using the emission factor, emission calculation factor, or mass balance method specified in paragraphs (c)(1) through (4) of this section, as appropriate. The mass balance method may only be used for batch operations without on-site production or transformation of controlled substances. For destruction processes that destroy controlled substances, the entity must calculate emissions using the procedures in paragraph (c)(4) of this section.

(1) Emission factor and emission calculation factor methods. To use the method in this paragraph (c)(1) for batch processes, each entity must use the methods in either paragraph (c)(1)(iii) (Emission Factor approach) or (iv) (Emission Calculation Factor approach) of this section. To use the method in this paragraph (c)(1) for continuous processes, the entity must first make a preliminary estimate of the emissions from each individual continuous process vent under paragraph (c)(1)(i) of this section. If the entity's continuous process operates under different conditions as part of normal operations, that entity must also define the different operating scenarios and make a preliminary estimate of the emissions from the vent for each operating scenario. Then, compare the preliminary estimate for each continuous process vent (summed across operating scenarios) to the criteria in paragraph (c)(1)(ii) of this section to determine whether the process vent meets the criteria for using the emission factor method described in paragraph (c)(1)(iii) of this section or whether the process vent meets the criteria for using the emission calculation factor method described in paragraph (c)(1)(iv) of this section. For continuous process vents that meet the criteria for using the emission factor method described in paragraph (c)(1)(iii) of this section and that have more than one operating scenario, compare the preliminary estimate for each operating scenario to the criteria in paragraph (c)(1)(iii)(B) of this section to determine whether an emission factor must be developed for that operating scenario.

(i) Preliminary estimate of emissions by process vent. Each entity must estimate the annual emissions of the controlled substance for each process vent within each operating scenario of a continuous process using the approaches specified in paragraph (c)(1)(i)(A) or (B) of this section, accounting for any destruction as specified in paragraph (c)(1)(i)(C) of this section. The entity must determine emissions of controlled substances by process vent by using measurements, by using calculations based on chemical engineering principles and chemical property data, or by conducting an engineering assessment. The entity may use previously conducted measurements, calculations, or assessments if they represent current process operating conditions or process operating conditions that would result in higher controlled substance emissions than the current operating conditions and if they were performed in accordance with paragraph (c)(1)(i)(A), (B), or (C) of this section, as applicable. The entity must document all data, assumptions, and procedures used in the calculations or engineering assessment and keep a record of the emissions determination as required by paragraph (f)(1) of this section.

(A) Engineering calculations. For process vent emission calculations, each entity may use any of paragraph (c)(1)(i)(A)(1), (2), or (3) of this section.

(1) U.S. Environmental Protection Agency, Emission Inventory Improvement Program, Volume II: Chapter 16, Methods for Estimating Air Emissions from Chemical Manufacturing Facilities, August 2007, Final (incorporated by reference, see § 82.27).

(2) Each entity may determine the controlled substance emissions from any process vent within the process using the procedures specified in § 63.1257(d)(2)(i) and (d)(3)(i)(B) of this chapter, except as specified in paragraphs (c)(1)(i)(A)(2)(i) through (iv) of this section. For the purposes of this section, use of the term “HAP” in § 63.1257(d)(2)(i) and (d)(3)(i)(B) of this chapter means “controlled substance.”

(i) To calculate emissions caused by the heating of a vessel without a process condenser to a temperature lower than the boiling point, each entity must use the procedures in § 63.1257(d)(2)(i)(C)(3) of this chapter.

(ii) To calculate emissions from depressurization of a vessel without a process condenser, each entity must use the procedures in § 63.1257(d)(2)(i)(D)(10) of this chapter.

(iii) To calculate emissions from vacuum systems, the terms used in equation 33 to § 63.1257(d)(2)(i)(E) of this chapter are defined as follows. Psystem means the absolute pressure of the receiving vessel. P i means the partial pressure of the controlled substance determined at the exit temperature and exit pressure conditions of the condenser or at the conditions of the dedicated receiver. Pj means the partial pressure of condensables (including controlled substances) determined at the exit temperature and exit pressure conditions of the condenser or at the conditions of the dedicated receiver. MWcontrolled substance means the molecular weight of the controlled substance determined at the exit temperature and exit pressure conditions of the condenser or at the conditions of the dedicated receiver.

(iv) To calculate emissions when a vessel is equipped with a process condenser or a control condenser, each entity must use the procedures in § 63.1257(d)(3)(i)(B) of this chapter, except as follows. Each entity must determine the flow rate of gas (or volume of gas), partial pressures of condensables, temperature (T), and controlled substance molecular weight (MWcontrolled substance) at the exit temperature and exit pressure conditions of the condenser or at the conditions of the dedicated receiver. Each entity must assume that all of the components contained in the condenser exit vent stream are in equilibrium with the same components in the exit condensate stream (except for noncondensables). Each entity must perform a material balance for each component, if the condensate receiver composition is not known. For the emissions from purging, the term for time, t, must be used in equation 12 to § 63.1257(d)(2)(i)(B) of this chapter. Emissions from empty vessel purging must be calculated using equation 36 to § 63.1257(d)(2)(i)(H) of this chapter and the exit temperature and exit pressure conditions of the condenser or the conditions of the dedicated receiver.

(3) Commercial software products that follow chemical engineering principles (e.g., including the calculation methodologies in paragraphs (c)(1)(i)(A)(1) and (2) of this section).

(B) Engineering assessments. For process vent emissions determinations, each entity may conduct an engineering assessment to calculate uncontrolled emissions. An engineering assessment includes, but is not limited to, the following:

(1) Previous test results, provided the tests are representative of current operating practices of the process.

(2) Bench-scale or pilot-scale test data representative of the process operating conditions.

(3) Maximum flow rate, controlled substance emission rate, concentration, or other relevant parameters specified or implied within a permit limit applicable to the process vent.

(4) Design analysis based on chemical engineering principles, measurable process parameters, or physical or chemical laws or properties.

(C) Impact of destruction for the preliminary estimate. If the process vent is vented to a destruction unit, each entity may reflect the impact of the destruction unit on emissions. In the emissions estimate, account for the following:

(1) The demonstrated destruction efficiencies of the device for the controlled substance in the vent stream for periods when the destruction device is in use.

(2) Any periods when the process vent is not vented to the destruction unit.

(D) Use of typical recent values. In the calculations in paragraphs (c)(1)(i)(A) through (C) of this section, the values used for the expected process activity and for the expected fraction of that activity, whose emissions will be vented to the properly functioning destruction unit, must be based on either typical recent values for the process or values that overestimate emissions from the process, unless there is a compelling reason to adopt a different value (e.g., installation of a destruction unit for a previously uncontrolled process). If there is such a reason, it must be documented in the monitoring plan.

(ii) Method selection for continuous process vents. (A) Based on the calculations under paragraph (c)(1)(i) of this section, as well as any subsequent measurements and calculations under this section, rank the process vents based on controlled substance emissions, upstream of any destruction unit, summed across all operating scenarios, from largest to smallest estimated annual emissions of controlled substances. The continuous process vents that comprise the top quartile of estimated annual emissions of controlled substances must use the method in paragraph (c)(1)(iii) of this section (Emission Factor approach). The process vent emissions will be based on the past 3 years for the ranking analysis.

(B) The remaining continuous process vents that comprise the bottom three quartiles of estimated annual emissions of controlled substances may use either the emission factor method specified in paragraph (c)(1)(iii) of this section (Emission Factor approach) or a method specified in paragraph (c)(1)(iv) of this section (Emission Calculation Factor approach).

(1) Each entity must conduct emission testing for process-vent-specific emission factor development upstream of the destruction unit.

(2) The emission testing for process-vent-specific emission factor development may be conducted on the outlet side of a wet scrubber in place for acid gas reduction, if there is no appreciable reduction in the controlled substance by the wet scrubber.

(iii) Process-vent-specific emission factor method. For each process vent, each entity must conduct an emission test according to the procedures in paragraph (d) of this section and measure the process activity, such as the feed rate, production rate, or other process activity rate, during the test as described in this paragraph (c)(1)(iii). All emissions test data and procedures used in developing emission factors must be documented according to paragraph (f) of this section. If more than one operating scenario applies to the process that contains the subject process vent, each entity must use the method in either paragraph (c)(1)(iii)(A) or (B) of this section.

(A) Conduct a separate emissions test for operation under each operating scenario.

(B) Conduct an emissions test for the operating scenario that is expected to have the largest emissions of controlled substances (considering both activity levels and emission calculation factors) on an annual basis. Also conduct an emissions test for each additional operating scenario for which the emission calculation factor differs by 15 percent or more from the emission calculation factor of the operating scenario that is expected to have the largest emissions(or of another operating scenario for which emission testing is performed), unless the difference between the operating scenarios is solely due to the application of a destruction unit to emissions under one of the operating scenarios. For any other operating scenarios, adjust the process-vent specific emission factor developed for the operating scenario that is expected to have the largest emissions (or for another operating scenario for which emission testing is performed) using the approach in paragraph (c)(1)(iii)(G) of this section.

(C) Each entity must measure the process activity, such as the process feed rate, process production rate, or other process activity rate, as applicable, during the emissions test and calculate the rate for the test period, in kg (or another appropriate metric) per hour.

(D) For continuous processes, each entity must calculate the hourly emission rate of each controlled substance using equation 1 to this paragraph (c)(1)(iii)(D) and determine the hourly emission rate of each controlled substance per process vent (and per operating scenario, as applicable) for the test run.

(E) Each entity must calculate a site-specific, process-vent-specific emission factor for each controlled substance for each process vent and each operating scenario, in kg of controlled substance per process activity rate (e.g., kg of feed or production), as applicable, using equation 2 to this paragraph (c)(1)(iii)(E). For continuous processes, divide the hourly controlled substance emission rate during the test by the hourly process activity rate during the test runs.

EPV = Mass of controlled substance p emitted from process vent v from process i, operating scenario j, during the emission test during test run r, for either continuous or batch (kg emitted/hr for continuous, kg emitted/batch for batch). ActivityEmissionTest = Process feed, process production, or other process activity rate for process i, operating scenario j, during the emission test during test run r (e.g., kg product/hr). r = Number of test runs performed during the emission test.

(F) If emissions testing is conducted upstream of the destruction unit, apply the destruction efficiencies of the device that have been demonstrated for the controlled substance in the vent stream to the controlled substance emissions for the process vent (and operating scenario, as applicable), using equation 3 to this paragraph (c)(1)(iii)(F). Each entity may apply the destruction efficiency only to the portion of the process activity during which emissions are vented to the properly functioning destruction unit (i.e., controlled).

EFPV-U = Emission factor (uncontrolled) for controlled substance p emitted from process vent v during process i, operating scenario j (kg emitted/kg product). ActivityU = Total process feed, process production, or other process activity for process i, operating scenario j, during the year for which the process vent is not vented to the properly functioning destruction unit (e.g., kg product). ActivityC = Total process feed, process production, or other process activity for process i, operating scenario j, during the year for which the process vent is vented to the properly functioning destruction unit (e.g., kg product). DE = Demonstrated destruction efficiency of the destruction unit (weight fraction).

(G) For process vents from processes with multiple operating scenarios, use equation 4 to this paragraph (c)(1)(iii)(G) to develop an adjusted process-vent-specific emission factor for each operating scenario whose emission calculation factor differs by less than 15 percent from the emission calculation factor of the operating scenario that is expected to have the largest emissions (or of another operating scenario for which emission testing is performed).

Equation 4 to Paragraph (c)(1)(iii)(G) Where: EFPVadj = Adjusted process-vent-specific emission factor for an untested operating scenario. ECFUT = Emission calculation factor for the untested operating scenario developed under paragraph (c)(4) of this section.

EPV = Mass of controlled substance p emitted from process vent v from process i, operating scenario j, for the year, considering destruction efficiency (kg). v = Number of process vents in process i, operating scenario j. o = Number of operating scenarios for process i.

(iv) Process-vent-specific emission calculation factor method. For each process vent within an operating scenario, determine controlled substances emissions by calculations and determine the process activity rate, such as the feed rate, production rate, or other process activity rate, associated with the emission rate.

(A) Each entity must calculate uncontrolled emissions of controlled substances by individual process vent, EPV, by using measurements, by using calculations based on chemical engineering principles and chemical property data, or by conducting an engineering assessment. Use the procedures in paragraph (c)(1)(i)(A) or (B) of this section, except paragraph (c)(1)(i)(B)(3) of this section. The procedures in paragraphs (c)(1)(i)(A) and (B) of this section may be applied either to batch process vents or to continuous process vents. The uncontrolled emissions must be based on a typical batch or production rate under a defined operating scenario. The process activity rate associated with the uncontrolled emissions must be determined. The methods, data, and assumptions used to estimate emissions for each operating scenario must be selected to yield a best estimate (expected value) of emissions rather than an over- or underestimate of emissions for that operating scenario. All data, assumptions, and procedures used in the calculations or engineering assessment must be documented according to paragraph (f) of this section.

(B) Each entity must calculate a site-specific, process-vent-specific emission calculation factor for each process vent each operating scenario, and each controlled substance, in kg of controlled substance per activity rate (e.g., kg of feed or production) as applicable, using equation 6 to this paragraph (c)(1)(iv)(B).

EPV = Average mass of controlled substance p emitted, based on calculations, from process vent v from process i, operating scenario j, during the period or batch for which emissions were calculated, for either continuous or batch (kg emitted/hr for continuous, kg emitted/batch for batch). Activity Representative = Process feed, process production, or other process activity rate corresponding to average mass of emissions based on calculations (e.g., kg product/hr for continuous, kg product/batch for batch).

(C) Each entity must calculate emissions of each controlled substance for the process vent (and for each operating scenario, as applicable) for the year by multiplying the process-vent-specific emission calculation factor by the total process activity, as applicable, for the year, using equation 7 to this paragraph (c)(1)(iv)(C).

Equation 7 to Paragraph (c)(1)(iv)(C) EPV = ECFPV * Activity Where: EPV = Mass of controlled substance p emitted from process vent v from process i, operating scenario j, for the year (kg). ECFPV = Emission calculation factor for controlled substance p emitted from process vent v during process i, operating scenario j (kg emitted/activity) (e.g., kg emitted/kg product). Activity = Process feed, process production, or other process activity for process i, operating scenario j, during the year.

(D) If the process vent is vented to a destruction unit, apply the demonstrated destruction efficiency of the device to the controlled substance emissions for the process vent (and operating scenario, as applicable), using equation 8 to this paragraph (c)(1)(iv)(D). Apply the destruction efficiency only to the portion of the process activity that is vented to the properly functioning destruction unit (i.e., controlled).

Equation 8 to Paragraph (c)(1)(iv)(D) EPV = ECFPV * (Activityu + Activityc * (1−DE)) Where: EPV = Mass of controlled substance p emitted from process vent v from process i, operating scenario j, for the year considering destruction efficiency (kg).

Equation 9 to Paragraph (c)(1)(iv)(E) Where: EPpi = Mass of controlled substance p emitted from process vents for process i for the year (kg). EPV = Mass of controlled substance p emitted from process vent v from process i, operating scenario j, for the year, considering destruction efficiency (kg). v = Number of process vents in process i, operating scenario j. o = Number of operating scenarios in process i.

(2) Calculate emissions for equipment leaks (EL). If activity is covered under paragraph (c)(1) of this section, each entity must calculate the emissions from pieces of equipment associated with processes covered under this section. If conducting monitoring of equipment in controlled substance service, monitoring must be conducted for those in light liquid and in gas and vapor service. If conducting monitoring of equipment in controlled substance service, the entity may exclude from monitoring each piece of equipment that is difficult-to-monitor, that is unsafe-to-monitor, that is insulated, or that is in heavy liquid service; the entity may exclude from monitoring each pump with dual mechanical seals, agitator with dual mechanical seals, pump with no external shaft, agitator with no external shaft; the entity may exclude from monitoring each pressure relief device in gas and vapor service with upstream rupture disk, each sampling connection system with closed-loop or closed-purge systems, and any pieces of equipment where leaks are routed through a closed vent system to a destruction unit. The entity must estimate emissions using another approach for those pieces of equipment excluded from monitoring. Equipment that is in controlled substance service for less than 300 hr/yr, equipment that is in vacuum service, pressure relief devices that are in light liquid service, and instrumentation systems are exempted from the requirements in this paragraph (c)(2).

(i) The emissions from equipment leaks must be calculated using any of the procedures in paragraphs (c)(2)(i)(A), (B), (C), or (D) of this section.

(A) Use of Average Emission Factor Approach in EPA protocol for equipment leak emission estimates. The emissions from equipment leaks may be calculated using the default Average Emission Factor Approach in EPA-453/R-95-017 (incorporated by reference, see § 82.27).

(B) Use of Other Approaches in EPA protocol for equipment leak emission estimates in conjunction with EPA Method 21. The emissions from equipment leaks may be calculated using one of the following methods in EPA-453/R-95-017 (incorporated by reference, see § 82.27): The Screening Ranges Approach; the EPA Correlation Approach; or the Unit-Specific Correlation Approach. If it is determined that EPA Method 21 in appendix A-7 to 40 CFR part 60 is appropriate for monitoring a controlled substance, and if the instrument is calibrated with a compound different from one or more of the controlled substances or surrogates to be measured, each entity must develop response factors for each controlled substance or for each surrogate to be measured using EPA Method 21. For each controlled substance or surrogate measured, the response factor must be less than 10. The response factor is the ratio of the known concentration of a controlled substance or surrogate to the observed meter reading when measured using an instrument calibrated with the reference compound.

(C) Use of Other Approaches in EPA protocol for equipment leak emission estimates in conjunction with site-specific leak monitoring methods. The emissions from equipment leaks may be calculated using one of the following methods in EPA-453/R-95-017 (incorporated by reference, see § 82.27): The Screening Ranges Approach; the EPA Correlation Approach; or the Unit-Specific Correlation Approach. Each entity may develop a site-specific leak monitoring method appropriate for monitoring controlled substances or surrogates to use along with these three approaches. The site-specific leak monitoring method must meet the requirements in paragraph (d)(5)(i) of this section.

(D) Use of site-specific leak monitoring methods. The emissions from equipment leaks may be calculated using a site-specific leak monitoring method. The site-specific leak monitoring method must meet the requirements in paragraph (d)(5)(i) of this section.

(ii) Each entity must collect information on the number of each type of equipment, the service of each piece of equipment (gas, light liquid, heavy liquid), the concentration of each controlled substance in the stream, and the time period each piece of equipment was in service (e.g., hours per year). Depending on which approach followed, the entity may be required to collect information for equipment on the associated screening data concentrations for greater than or equal to 10,000 ppmv and associated screening data concentrations for less than 10,000 ppmv; associated actual screening data concentrations; or associated screening data and leak rate data (i.e., bagging) used to develop a unit-specific correlation.

(iii) Calculate and sum the emissions of each controlled substance in kilograms per year for equipment pieces for each process, EELp, annually. Each entity must include and estimate emissions for types of equipment that are excluded from monitoring, including difficult-to-monitor, unsafe-to-monitor and insulated pieces of equipment, pieces of equipment in heavy liquid service, pumps with dual mechanical seals, agitators with dual mechanical seals, pumps with no external shaft, agitators with no external shaft, pressure relief devices in gas and vapor service with upstream rupture disk, sampling connection systems with closed-loop or closed purge systems, and pieces of equipment where leaks are routed through a closed vent system to a destruction unit.

(3) Calculate total controlled substance emissions for each process and for production or transformation processes at the facility. (i) Estimate annually the total mass of each controlled substance emitted from each process, including emissions from process vents in paragraphs (c)(1)(iii) and (iv) of this section, as appropriate, and from equipment leaks in paragraph (c)(2) of this section, using equation 10 to this paragraph (c)(3)(i).

EPpi = Mass of controlled substance p emitted from all process vents and all operating scenarios in process i, annually (kg/year, calculated in equation 5 or 9 to this section, as appropriate). EELpi = Mass of controlled substance p emitted from equipment leaks for pieces of equipment for process i, annually (kg/year, calculated in paragraph (c)(2)(iii) of this section).

(ii) Estimate annually the total mass of each controlled substance emitted at the facility from each applicable process listed in paragraph (b)(2) of this section using equation 11 to this paragraph (c)(3)(ii).

(4) Mass balance method. Before using the mass balance approach to estimate your controlled substance emissions from a process, you must ensure that the process and the equipment and methods used to measure the process meet either the error limits described in this paragraph (c)(4) and calculated under paragraph (c)(4)(i) of this section or the requirements specified in paragraph (d)(4)(viii) of this section. If you choose to calculate the error limits, you must estimate the absolute and relative errors associated with using the mass balance approach on that process using equations 12 through 15 to this section in conjunction with equations 16 through 21 to this section. You may use the mass-balance approach to estimate emissions from the process if this calculation results in an absolute error of less than or equal to one metric ton of controlled substance per year or a relative error of less than or equal to 10 percent of the estimated controlled substance emissions. If you do not meet either of the error limits or the requirements of paragraph (d)(4)(viii) of this section, you must use the emission factor approach detailed in paragraphs (c)(1) through (3) of this section to estimate emissions from the process.

(i) To perform the calculation, you must first calculate the absolute and relative errors associated with the quantities calculated using either equations 18 through 21 to this section or equation 28 to paragraph (c)(4)(xv) of this section. Alternatively, you may estimate these errors based on the variability of previous process measurements (e.g., the variability of measurements of stream concentrations), provided these measurements are representative of the current process and current measurement devices and techniques. Once errors have been calculated for the quantities in these equations, those errors must be used to calculate the errors in equations 16 and 17 to this section. You may omit the errors associated with equations 22 through 24 to this section.

(A) Where the measured quantity is a mass, the error in the mass must be equated to the accuracy or precision (whichever is larger) of the flowmeter, scale, or combination of volumetric and density measurements at the flow rate or mass measured.

(B) Where the measured quantity is a concentration of a stream component, the error of the concentration must be equated to the accuracy or precision (whichever is larger) with which you estimate the mean concentration of that stream component, accounting for the variability of the process, the frequency of the measurements, and the accuracy or precision (whichever is larger) of the analytical technique used to measure the concentration at the concentration measured. If the variability of process measurements is used to estimate the error, this variability shall be assumed to account both for the variability of the process and the precision of the analytical technique. Use standard statistical techniques such as the student's t distribution to estimate the error of the mean of the concentration measurements as a function of process variability and frequency of measurement.

(C) Equation 12 to this paragraph (c)(4)(i)(C) provides the general formula for calculating the absolute errors of sums and differences where the sum, S, is the summation of variables measured, a, b, c, etc. (e.g., S = a + b + c).

(E) Equation 14 to this paragraph (c)(4)(i)(E) provides the general formula for calculating the absolute errors of products (e.g., flow rates of controlled substances calculated as the product of the flow rate of the stream and the concentration of the controlled substance in the stream), where the product, P, is the result of multiplying the variables measured, a, b, c, etc. (e.g., P = a*b*c).

Equation 14 to Paragraph (c)(4)(i)(E) ePA = (a * b * c)(e 2a + e 2b + e 2c) 1/2 Where: ePA = Absolute error of the product, expressed as one half of a 95 percent confidence interval. ea = Relative error of a, expressed as one half of a 95 percent confidence interval. eb = Relative error of b, expressed as one half of a 95 percent confidence interval. ec = Relative error of c, expressed as one half of a 95 percent confidence interval.

(F) Equation 15 to this paragraph (c)(4)(i)(F) provides the general formula for calculating the relative errors of products.

Equation 15 to Paragraph (c)(4)(i)(F) Where: ePR = Relative error of the product, expressed as one half of a 95 percent confidence interval. ePA = Absolute error of the product, expressed as one half of a 95 percent confidence interval. a*b*c = Product of the variables measured.

(G) Calculate the absolute error of the controlled substance emissions estimate by performing a preliminary estimate of the annual controlled substance emissions of the process using the method in paragraph (c)(4)(i)(H) of this section. Multiply this result by the relative error calculated for the mass of halogen emitted from the process in equation 15 to paragraph (c)(4)(i)(F) of this section.

(H) To estimate the annual controlled substance emissions of the process for use in the error estimate, apply the methods set forth in paragraphs (c)(4)(ii) through (vii) and (ix) through (xvi) of this section to representative process measurements. If these process measurements represent less than one year of typical process activity, adjust the estimated emissions to account for one year of typical process activity. To estimate the terms FERd, FEP, and FEBk for use in the error estimate for equations 22, 23, and 24 to this section, you must either use emission testing, monitoring of emitted streams, and/or engineering calculations or assessments.

This calculation must be performed using equation 17 to this paragraph (c)(4)(iii). An element other than a halogen may be used in the mass-balance equation, provided the element occurs in all of the controlled substances fed into or generated by the process. In this case, the mass fractions of the element in the reactants, products, and byproducts must be calculated as appropriate for that element.

These emission characterization measurements must meet the requirements in paragraph (c)(4)(viii)(A), (B), or (C) of this section, as appropriate. The sum of the terms must equal 1. You must document the data and calculations that are used to speciate individual compounds and to estimate FERd, FEP, and FEBk. Exclude from your calculations the halogen included in FD. For example, exclude halogen-containing compounds that are not controlled substances and that result from the destruction of controlled substances by any destruction devices (e.g., the mass of HF created by combustion of a chlorofluorocarbon). However, include emissions of controlled substance that survive the destruction process.

(A) If the calculations under paragraph (b)(1)(viii) of this section, or any subsequent measurements and calculations under this subpart, indicate that the process emits 0.1 metric tons controlled substance or more, estimate the emissions from each process vent, considering controls, using the methods in paragraph (c)(1)(i) of this section.

(d) Monitoring and QA/QC requirements—(1) Initial scoping speciation to identify controlled substances from transformation processes. Each entity that transforms controlled substances must conduct an initial scoping speciation to identify all controlled substances that may be generated or emitted from transformation processes that are subject to this section. The entity is not required to quantify emissions under this initial scoping speciation. Only controlled substance products and byproducts that occur in greater than trace concentrations in at least one stream must be identified under this paragraph (d)(1).

(i) Procedure. To conduct the scoping speciation, select the stream(s) (including process streams or destroyed streams) or process vent(s) that would be expected to individually or collectively contain all of the controlled substance byproducts of the process at their maximum concentrations and sample and analyze the contents of these selected streams or process vents. For example, if controlled substance byproducts are separated into one low-boiling-point and one high-boiling-point stream, sample and analyze both of these streams. Alternatively, each entity may sample and analyze streams where controlled substance byproducts occur at less than their maximum concentrations, but the entity must ensure that the sensitivity of the analysis is sufficient to compensate for the expected difference in concentration. For example, if the entity samples and analyzes streams where controlled substance byproducts are expected to occur at one half their maximum concentrations elsewhere in the process, that entity must ensure that the sensitivity of the analysis is sufficient to detect controlled substance byproducts that occur at concentrations of 0.05 percent or higher. The entity does not have to sample and analyze every stream or process vent, i.e., the entity does not have to sample and analyze a stream or process vent that contains only controlled substances that are contained in other streams or process vents that are being sampled and analyzed. Sampling and analysis must be conducted according to the procedures in paragraph (d)(5) of this section.

(ii) Previous measurements. If testing of streams (including process streams or destroyed streams) or process vents were conducted less than 5 years before November 12, 2024, and the testing meets the requirements in paragraph (d)(1)(i) of this section, each entity may use the previous testing to satisfy this requirement.

(2) Emission factor testing. If controlled substance emissions are determined using the site-specific process-vent-specific emission factor, each entity must meet the requirements in paragraphs (d)(2)(i) through (vii) of this section.

(i) Process vent testing. Conduct an emissions test that is based on representative performance of the process or operating scenario(s) of the process, as applicable. For process vents for which each entity performed an initial scoping speciation, include in the emission test any controlled substance that was identified in the initial scoping speciation. For process vents for which the entity did not perform an initial scoping speciation, include in the emission test any controlled substance that occurs in more than trace concentrations in the vent stream or, where a destruction unit is used, in the inlet to the destruction unit. The entity may include startup and shutdown events if the testing is sufficiently long or comprehensive to ensure that such events are not overrepresented in the emission factor. Malfunction events must not be included in the testing. If the entity does not detect a controlled substance that was identified in the scoping speciation or that occurs in more than trace concentrations in the vent stream or in the inlet to the destruction unit, assume that controlled substance was emitted from the process vent, or from the destruction unit, at a concentration of one third of the detection limit.

(ii) Number of runs. For continuous processes, sample the process vent for a minimum of three runs of 1 hour each. If the relative standard deviation (RSD) of the emission factor calculated based on the first three runs is greater than or equal to 0.15 for the emission factor, continue to sample the process vent for an additional three runs of 1 hour each.

(iii) Process activity measurements. Determine the mass rate of process feed, process production, or other process activity as applicable during the test using flow meters, weigh scales, or other measurement devices or instruments with an accuracy and precision of ±1 percent of full scale or better. These devices may be the same plant instruments or procedures that are used for accounting purposes (such as weigh hoppers, belt weigh feeders, combination of volume measurements and bulk density, etc.) if these devices or procedures meet the requirement. For monitoring ongoing process activity, use flow meters, weigh scales, or other measurement devices or instruments with an accuracy and precision of ±1 percent of full scale or better.

(iv) Sample each process. If process vents from separate processes are manifolded together to a common vent or to a common destruction unit, each entity must follow paragraph (d)(2)(iv)(A), (B), or (C) of this section.

(A) Each entity may sample emissions from each process in the ducts upstream from the point where the emissions are combined.

(B) Each entity may sample in the common duct or at the outlet of the destruction unit when only one process is operating.

(C) Each entity may sample the combined emissions and use engineering calculations and assessments as specified in paragraph (c)(1)(iv) of this section to allocate the emissions to each manifolded process vent, provided the sum of the calculated controlled substance emissions across the individual process vents is within 20 percent of the total controlled substance emissions measured during the manifolded testing.

(v) Emission test results. The results of an emission test must include the analysis of samples, number of test runs, the results of the RSD analysis, the analytical method used, determination of emissions, the process activity, and raw data and must identify the process, the operating scenario, the process vents tested, and the controlled substances that were included in the test. The emissions test report must contain all information and data used to derive the process-vent-specific emission factor, as well as key process conditions during the test. Key process conditions include those that are normally monitored for process control purposes and may include but are not limited to yields, pressures, temperatures, etc. (e.g., of reactor vessels, distillation columns).

(vi) Emissions testing frequency. Each entity must conduct emissions testing to develop the process-vent-specific emission factor under paragraph (d)(2)(vi)(A) or (B) of this section, whichever occurs first:

(A) 5-year revision. Conduct an emissions test every 5 years. In the calculations under paragraph (c) of this section, apply the revised process-vent-specific emission factor to the process activity that occurs after the revision.

(B) Operating scenario change that affects the emission factor. For planned operating scenario changes, each entity must estimate and compare the emission calculation factors for the changed operating scenario and for the original operating scenario whose process vent specific emission factor was measured. Use the calculation methods in paragraph (c)(1)(iv) of this section. If the emission calculation factor for the changed operating scenario is 15 percent or more different from the emission calculation factor for the previous operating scenario (this includes the cumulative change in the emission calculation factor since the most recent emissions test), the entity must conduct an emissions test to update the process-vent-specific emission factor, unless the difference between the operating scenarios is solely due to the application of a destruction unit to emissions under the changed operating scenario. Conduct the test before February 14 of the calendar year that immediately follows the change. In the calculations under paragraph (c) of this section, apply the revised process-vent-specific emission factor to the process activity that occurs after the operating scenario change.

(vii) Previous measurements. If an emissions test was conducted less than 5 years before November 12, 2024, and the emissions testing meets the requirements in paragraphs (d)(2)(i) through (vii) of this section, the entity may use the previous emissions testing to develop process-vent-specific emission factors. For purposes of paragraph (d)(2)(vi)(A) of this section, the date of the previous emissions test rather than November 12, 2024, shall constitute the beginning of the 5-year re-measurement cycle.

(3) Emission calculation factor monitoring. If controlled substance emissions were determined using the site-specific process-vent-specific emission calculation factor, each entity must meet the requirements in paragraphs (d)(3)(i) through (iv) of this section.

(i) Operating scenario. Perform the emissions calculation for the process vent based on representative performance of the operating scenario of the process. If more than one operating scenario applies to the process that contains the subject process vent, you must conduct a separate emissions calculation for operation under each operating scenario. For each continuous process vent that contains more than trace concentrations of any controlled substance and for each batch process vent that contains more than trace concentrations of any controlled substance, develop the process-vent-specific emission calculation factor for each operating scenario. For continuous process vents, determine the emissions based on the process activity for the representative performance of the operating scenario. For batch process vents, determine emissions based on the process activity for each typical batch operating scenario.

(ii) Process activity measurements. Use flow meters, weigh scales, or other measurement devices or instruments with an accuracy and precision of ±1 percent of full scale or better for monitoring ongoing process activity.

(iii) Emission calculation results. The emission calculation must be documented by identifying the process, the operating scenario, and the process vent(s). The documentation must contain the information and data used to calculate the process-vent-specific emission calculation factor.

(iv) Operating scenario change that affects the emission calculation factor. For planned operating scenario changes that are expected to change the process-vent-specific emission calculation factor, each entity must conduct an emissions calculation to update the process-vent-specific emission calculation factor. In the calculations under paragraph (c) of this section, apply the revised emission calculation factor to the process activity that occurs after the operating scenario change.

(v) Previous calculations. If an emissions calculation was performed for the process vent and operating scenario less than 5 years before November 12, 2024, and the emissions calculation meets the requirements in paragraphs (c)(1)(iv)(A) and (B) of this section and in paragraphs (d)(3)(i) through (iv) of this section, each entity may use the previous calculation to develop the site-specific process-vent-specific emission calculation factor.

(4) Mass balance monitoring. If you determine controlled substance emissions from any process using the mass balance method under paragraph (c)(4) of this section, you must estimate the total mass of each controlled substance emitted from that process at least monthly. Only streams that contain greater than trace concentrations of halogen-containing reactants, products, or byproducts must be monitored under this paragraph (d)(4).

(i) Mass measurements. Measure the following masses on a monthly or more frequent basis using flowmeters, weigh scales, or a combination of volumetric and density measurements with accuracies and precisions that allow the facility to meet the error criteria in paragraph (c)(4)(i) of this section:

(A) Total mass of each halogen-containing product produced. Account for any used halogen-containing product added into the production process upstream of the output measurement as directed at §§ 98.413(b) and 98.414(b) of this chapter.

(B) Total mass of each halogen-containing reactant fed into the process.

(C) The mass removed from the process in each stream fed into the destruction device.

(D) The mass removed from the process in each recaptured stream.

(ii) Concentration measurements for use with paragraph (c)(4)(iv) of this section. If you use paragraph (c)(4)(iv) of this section to estimate the mass of halogen in destroyed or recaptured streams, measure the following concentrations at least once each calendar month during which the process is operating, on a schedule to ensure that the measurements are representative of the full range of process conditions (e.g., catalyst age). Measure more frequently if this is necessary to meet the error criteria in paragraph (c)(4)(i) of this section. Use equipment and methods (e.g., gas chromatography) that comply with paragraph (d)(5) of this section and that have an accuracy and precision that allow the facility to meet the error criteria in paragraph (c)(4)(i) of this section. Only halogen-containing reactants, products, and byproducts that occur in a stream in greater than trace concentrations must be monitored under this paragraph (d)(4)(ii).

(A) The concentration (mass fraction) of the halogen-containing product in each stream that is fed into the destruction device.

(B) The concentration (mass fraction) of each halogen-containing byproduct in each stream that is fed into the destruction device.

(C) The concentration (mass fraction) of each halogen-containing reactant in each stream that is fed into the destruction device.

(D) The concentration (mass fraction) of each halogen-containing byproduct in each stream that is recaptured (cBkl).

(iii) Concentration measurements for use with paragraph (c)(4)(xv) of this section. If you use paragraph (c)(4)(xv) of this section to estimate the mass of halogen in destroyed or recaptured streams, measure the concentrations listed in paragraphs (d)(4)(iii)(A) and (B) of this section at least once each calendar month during which the process is operating, on a schedule to ensure that the measurements are representative of the full range of process conditions (e.g., catalyst age). Measure more frequently if this is necessary to meet the error criteria in paragraph (c)(4)(i) of this section. Use equipment and methods (e.g., gas chromatography) that comply with paragraph (d)(5) of this section and that have an accuracy and precision that allow the facility to meet the error criteria in paragraph (c)(4)(i) of this section. Only halogen-containing reactants, products, and byproducts that occur in a stream in greater than trace concentrations must be monitored under this paragraph (d)(4)(iii).

(A) The concentration (mass fraction) of total halogen in each stream that is fed into the destruction device.

(B) The concentration (mass fraction) of total halogen in each stream that is recaptured.

(iv) Emissions characterization: process vents emitting 0.1 metric tons or more. To characterize emissions from any process vent emitting 0.1 metric tons of controlled substances or more, comply with paragraphs (d)(4)(iv)(A) through (E) of this section, as appropriate. Only halogen-containing reactants, products, and byproducts that occur in a stream in greater than trace concentrations must be monitored under this paragraph (d)(4)(iv).

(A) Uncontrolled emissions. If emissions from the process vent are not routed through a destruction device, sample and analyze emissions at the process vent or stack or sample and analyze emitted streams before the process vent. If the process has more than one operating scenario, you must either perform the emission characterization for each operating scenario or perform the emission characterization for the operating scenario that is expected to have the largest emissions and adjust the emission characterization for other scenarios using engineering calculations and assessments as specified in paragraph (c)(1)(iv) of this section. To perform the characterization, take three samples under conditions that are representative for the operating scenario. Measure the concentration of each halogen-containing compound in each sample. Use equipment and methods that comply with paragraph (d)(5) of this section. Calculate the average concentration of each halogen-containing compound across all three samples.

(B) Controlled emissions using paragraph (c)(4)(xv) of this section. If you use paragraph (c)(4)(xv) of this section to estimate the total mass of halogen in destroyed or recaptured streams, and if the emissions from the process vent are routed through a destruction device, characterize emissions as specified in paragraph (d)(4)(iv)(A) of this section before the destruction device. Apply the destruction efficiency demonstrated for each controlled substance in the destroyed stream to that controlled substance. Exclude from the characterization halogen-containing compounds that are not controlled substances.

(C) Controlled emissions using paragraph (c)(4)(iv) of this section. If you use paragraph (c)(4)(iv) of this section to estimate the mass of halogen in destroyed or recaptured streams, and if the emissions from the process vent are routed through a destruction device, characterize the process vent's emissions monthly (or more frequently) using the monthly (or more frequent) measurements under paragraphs (d)(4)(i)(C) and (d)(4)(ii)(A) through (C) of this section. Apply the destruction efficiency demonstrated for each controlled substance in the destroyed stream to that controlled substance. Exclude from the characterization halogen-containing compounds that are not controlled substances.

(D) Emissions characterization frequency. You must repeat emission characterizations performed under paragraphs (d)(4)(iv)(A) and (B) of this section under paragraph (d)(4)(iv)(D)(1) or (2) of this section, whichever occurs first:

(1) 5-year revision. Repeat the emission characterization every 5 years. In the calculations under paragraph (c) of this section, apply the revised emission characterization to the process activity that occurs after the revision.

(2) Operating scenario change that affects the emission characterization. For planned operating scenario changes, you must estimate and compare the emission calculation factors for the changed operating scenario and for the original operating scenario whose process vent specific emission factor was measured. Use the engineering calculations and assessments specified in paragraph (c)(1)(iv) of this section. If the share of total halogen-containing compound emissions represented by any controlled substance changes under the changed operating scenario by 15 percent or more of the total, relative to the previous operating scenario (this includes the cumulative change in the emission calculation factor since the last emissions test), you must repeat the emission characterization. Perform the emission characterization before February 14 of the year that immediately follows the change. In the calculations under paragraph (c) of this section, apply the revised emission characterization to the process activity that occurs after the operating scenario change.

(E) Subsequent measurements. If a process vent with controlled substance emissions less than 0.1 metric tons, per paragraph (c)(1)(ii) of this section, is later found to have controlled substance emissions of 0.1 metric tons or greater, you must perform an emission characterization under this paragraph (d)(4)(iv)(E) during the following year.

(v) Emissions characterization: process vents emitting less than 0.1 metric tons. To characterize emissions from any process vent emitting less than 0.1 metric tons, comply with paragraphs (d)(4)(v)(A) and (B) of this section, as appropriate. Only halogen-containing reactants, products, and byproducts that occur in a stream in greater than trace concentrations must be monitored under this paragraph (d)(4)(v).

(A) Uncontrolled emissions. If emissions from the process vent are not routed through a destruction device, emission measurements must consist of sampling and analysis of emissions at the process vent or stack, sampling and analysis of emitted streams before the process vent, previous test results, provided the tests are representative of current operating conditions of the process, or bench-scale or pilot-scale test data representative of the process operating conditions.

(B) Controlled emissions using paragraph (c)(4)(xv) of this section. If you use paragraph (c)(4)(xv) of this section to estimate the total mass of halogen in destroyed or recaptured streams, and if the emissions from the process vent are routed through a destruction device, characterize emissions as specified in paragraph (d)(4)(v)(A) of this section before the destruction device. Apply the destruction efficiency demonstrated for each controlled substance in the destroyed stream to that controlled substance. Exclude from the characterization halogen-containing compounds that are not controlled substances.

(C) Controlled emissions using paragraph (c)(4)(iv) of this section. If you use paragraph (c)(4)(iv) of this section to estimate the mass of halogen in destroyed or recaptured streams, and if the emissions from the process vent are routed through a destruction device, characterize the process vent's emissions monthly (or more frequently) using the monthly (or more frequent) measurements under paragraphs (d)(4)(i)(C) and (d)(4)(ii)(A) through (C) of this section. Apply the destruction efficiency demonstrated for each controlled substance in the destroyed stream to that controlled substance. Exclude from the characterization halogen-containing compounds that are not controlled substances.

(vi) Emissions characterization: emissions not accounted for by process vent estimates. Calculate the weighted average emission characterization across the process vents before any destruction devices. Apply the weighted average emission characterization for all the process vents to any halogen emissions that are not accounted for by process vent estimates.

(vii) Impurities in reactants. If any halogen-containing impurity is fed into a process along with a reactant (or other input) in greater than trace concentrations, this impurity shall be monitored under this section and included in the calculations under paragraph (c) of this section in the same manner as reactants fed into the process, fed into the destruction device, recaptured, or emitted, except the concentration of the impurity in the mass fed into the process shall be measured, and the mass of the impurity fed into the process shall be calculated as the product of the concentration of the impurity and the mass fed into the process. The mass of the reactant fed into the process may be reduced to account for the mass of the impurity.

(viii) Alternative to error calculation. As an alternative to calculating the relative and absolute errors associated with the estimate of emissions under this paragraph (d)(4), you may comply with the precision, accuracy, and measurement and calculation frequency requirements of paragraph (d)(4)(viii)(A) through (C) of this section.

(A) Mass measurements. Measure the masses specified in paragraph (d)(4)(i) of this section using flowmeters, weigh scales, or a combination of volumetric and density measurements with accuracies and precisions of ±0.2 percent of full scale or better.

(B) Concentration measurements. Measure the concentrations specified in paragraph (d)(4)(ii) or (iii) of this section, as applicable, using analytical methods with accuracies and precisions of ±10 percent or better.

(C) Measurement and calculation frequency. Perform the mass measurements specified in paragraph (d)(4)(i) of this section and the concentration measurements specified in paragraph (d)(4)(ii) or (iii) of this section, as applicable, at least weekly, and calculate emissions at least weekly.

(5) Emission and stream testing, including analytical methods. Select and document testing and analytical methods as follows:

(i) Sampling and mass measurement for emission testing. For emission testing in process vents or at the stack, use methods for sampling, measuring volumetric flow rates, non-controlled substance gas analysis, and measuring stack gas moisture that have been validated using a scientifically sound validation protocol.

(A) Sample and velocity traverses. Acceptable methods include but are not limited to EPA Method 1 or 1A in appendix A-1 to 40 CFR part 60.

(B) Velocity and volumetric flow rates. Acceptable methods include but are not limited to EPA Method 2, 2A, 2B, 2C, 2D, 2F, or 2G in appendix A-1 to 40 CFR part 60. Alternatives that may be used for determining flow rates include Other Test Method 24 (incorporated by reference, see § 82.27) and ALT-012 (incorporated by reference, see § 82.27).

(C) Non-controlled substance gas analysis. Acceptable methods include but are not limited to EPA Method 3, 3A, or 3B in appendix A-1 to 40 CFR part 60.

(D) Stack gas moisture. Acceptable methods include but are not limited to EPA Method 4 in appendix A-1 to 40 CFR part 60.

(ii) Analytical methods. Use a quality-assured analytical measurement technology capable of detecting the analyte of interest at the concentration of interest and use a sampling and analytical procedure validated with the analyte of interest at the concentration of interest. Where calibration standards for the analyte are not available, a chemically similar surrogate may be used. Acceptable analytical measurement technologies include but are not limited to gas chromatography (GC) with an appropriate detector, infrared (IR), Fourier transform infrared (FTIR), and nuclear magnetic resonance (NMR). Acceptable methods for determining controlled substances include EPA Method 18 in appendix A-1 to 40 CFR part 60, EPA Method 320 in appendix A to 40 CFR part 63, EPA 430-R-10-003 (incorporated by reference, see § 82.27), ASTM D6348-03 (incorporated by reference, see § 82.27), or other analytical methods validated using EPA Method 301 at appendix A to 40 CFR part 63. The validation protocol may include analytical technology manufacturer specifications or recommendations.

(iii) Documentation in the monitoring plan. Describe the sampling, measurement, and analytical method(s) used under paragraphs (d)(5)(i) and (ii) of this section in the monitoring plan. Identify the methods used to obtain the samples and measurements listed under paragraphs (d)(5)(i)(A) through (D) of this section. At a minimum, include in the description of the analytical method a description of the analytical measurement equipment and procedures, quantitative estimates of the method's accuracy and precision for the analytes of interest at the concentrations of interest, as well as a description of how these accuracies and precisions were estimated, including the validation protocol used.

(6) Emission monitoring for pieces of equipment. If conducting a site-specific leak detection method or monitoring approach for pieces of equipment, each entity must follow paragraph (d)(6)(i) or (ii) of this section and follow paragraph (d)(6)(iii) of this section.

(i) Site-specific leak monitoring approach. Each entity may develop a site-specific leak monitoring approach. The entity must validate the leak monitoring method and describe the method and the validation in the monitoring plan. To validate the site-specific method, the entity may, for example, release a known rate of the controlled substances or surrogates of interest, or may compare the results of the site-specific method to those of a method that has been validated for the controlled substances or surrogates of interest. In the description of the leak detection method and its validation, include a detailed description of the method, including the procedures and equipment used and any sampling strategies. Also include the rationale behind the method, including why the method is expected to result in an unbiased estimate of emissions from equipment leaks. If the method is based on methods that are used to detect or quantify leaks or other emissions in other regulations, standards, or guidelines, identify and describe the regulations, standards, or guidelines and why their methods are applicable to emissions of controlled substances or surrogates from leaks. Account for possible sources of error in the method, e.g., instrument detection limits, measurement biases, and sampling biases. Describe validation efforts, including but not limited to any comparisons against standard leaks or concentrations, any comparisons against other methods, and their results. If using the Screening Ranges Approach, the EPA Correlation Approach, or the Unit-Specific Correlation Approach with a monitoring instrument that does not meet all of the specifications in EPA Method 21 in appendix A-7 to 40 CFR part 60, then explain how and why the monitoring instrument, as used at the facility, would nevertheless be expected to accurately detect and quantify emissions of controlled substances or surrogates from process equipment, and describe how accuracy was verified. For all methods, provide a quantitative estimate of the accuracy and precision of the method.

(ii) EPA Method 21 monitoring. If it is determined that EPA Method 21 in appendix A-7 to 40 CFR part 60 is appropriate for monitoring a controlled substance, conduct the screening value concentration measurements using EPA Method 21 to determine the screening range data or the actual screening value data for the Screening Ranges Approach, EPA Correlation Approach, or the Unit-Specific Correlation Approach. For the one-time testing to develop the Unit-Specific Correlation equations in EPA-453/R-95-017 (incorporated by reference, see § 82.27), conduct the screening value concentration measurements using EPA Method 21 and the bagging procedures to measure mass emissions. Concentration measurements of bagged samples must be conducted using gas chromatography following analytical procedures in EPA Method 18 in appendix A-1 to 40 CFR part 60 or other method according to this paragraph (d)(6). Use methane or other appropriate compound as the calibration gas.

(iii) Frequency of measurement and sampling. If estimating emissions based on monitoring of equipment, each entity must conduct monitoring at least annually. Sample at least one-third of equipment annually (except for equipment that is unsafe-to-monitor, difficult-to-monitor, insulated, or in heavy liquid service, pumps with dual mechanical seals, agitators with dual mechanical seals, pumps with no external shaft, agitators with no external shaft, pressure relief devices in gas and vapor service with an upstream rupture disk, sampling connection systems with closed-loop or closed purge systems, and pieces of equipment whose leaks are routed through a closed vent system to a destruction unit), changing the sample each year such that at the end of three years, all equipment in the process (that is not subject to the above-listed exceptions) has been monitored. If estimating emissions based on a sample of the equipment in the process, ensure that the sample is representative of the equipment in the process. If there are multiple processes that have similar types of equipment in similar service, and that perform activities on similar controlled substances (in terms of chemical composition, molecular weight, and vapor pressure) at similar pressures and concentrations, then the entity may annually sample all of the equipment in one third of these processes rather than one third of the equipment in each process.

(7) Destruction unit performance testing. If venting or otherwise feeding controlled substances into a destruction unit and apply the destruction efficiency of the device to one or more controlled substances in paragraph (c) of this section, each entity must conduct emissions testing to determine the destruction efficiency for each controlled substance to which the destruction efficiency was applied. The entity must either determine the destruction efficiency for the most-difficult-to-destroy controlled substance fed into the device (or a surrogate that is still more difficult to destroy) and apply that destruction efficiency to all the controlled substances fed into the device or alternatively determine different destruction efficiencies for different groups of controlled substances using the most-difficult-to-destroy controlled substance of each group (or a surrogate that is still more difficult to destroy).

(i) Destruction efficiency testing. Each entity must sample the inlet and outlet of the destruction unit for a minimum of three runs of 1 hour each to determine the destruction efficiency. The entity must conduct the emissions testing using the methods in paragraph (d)(5) of this section. To determine the destruction efficiency, emission testing must be conducted when operating at high loads reasonably expected to occur (i.e., representative of high total controlled substance load that will be sent to the device) and when destroying the most-difficult-to-destroy controlled substance (or a surrogate that is still more difficult to destroy) that is fed into the device from the processes subject to this section or that belongs to the group of controlled substances for which destruction efficiency is to be established. If the outlet concentration of a controlled substance that is fed into the device is below the detection limit of the method, the entity may use an outlet concentration of one-third the detection limit to estimate the destruction efficiency.

(A) For all other controlled substances that are vented to the destruction unit in any stream in more than trace concentrations, each entity must test and determine the destruction efficiency achieved for the most-difficult-to-destroy controlled substance or surrogate vented to the destruction unit. Examples of acceptable surrogates include the Class 1 compounds (ranked 1 through 34) in Appendix D, Table D-1 of “Guidance on Setting Permit Conditions and Reporting Trial Burn Results; Volume II of the Hazardous Waste Incineration Guidance Series,” January 1989, EPA Publication EPA 625/6-89/019. A copy of this publication can be obtained by contacting the Environmental Protection Agency, 1200 Pennsylvania Avenue NW., Washington, DC 20460, (202) 272-0167, https://www.epa.gov.

(B) [Reserved]

(ii) Destruction efficiency testing frequency. Each entity must conduct emissions testing to determine the destruction efficiency as provided in paragraph (d)(7)(ii)(A) or (B) of this section, whichever occurs first:

(A) Conduct an emissions test every 5 years. In the calculations under paragraph (c) of this section, apply the updated destruction efficiency to the destruction that occurs after the test.

(B) Destruction unit changes that affect the destruction efficiency. If making a change to the destruction unit that would be expected to affect the destruction efficiency, each entity must conduct an emissions test to update the destruction efficiency. Conduct the test before February 14 of the year that immediately follows the change. In the calculations under paragraph (c) of this section, apply the updated destruction efficiency to the destruction that occurs after the change to the device.

(iii) Previous testing. If an emissions test was conducted within the 5 years prior to November 12, 2024, and the emissions testing meets the requirements in paragraph (d)(7)(i) of this section, each entity may use the destruction efficiency determined during this previous emissions testing. For purposes of paragraph (d)(7)(ii)(A) of this section, the date of the previous emissions test rather than November 12, 2024, shall constitute the beginning of the 5-year re-measurement cycle.

(iv) Hazardous waste combustor testing. If a destruction unit used to destroy a controlled substance is subject to testing under subpart EEE of part 63 of this chapter or any portion of parts 260 through 270 of this chapter, each entity may apply the destruction efficiency specifically determined for controlled substances under that test if the testing meets the criteria in paragraph (d)(7)(i)(A) of this section. If the testing of the destruction efficiency under subpart EEE of part 63 was conducted more than 5 years ago, the entity may use the most recent destruction efficiency test provided that the design, operation, and maintenance of the destruction unit has not changed since the last destruction efficiency test in a manner that could affect the ability to achieve the destruction efficiency, and the hazardous waste is fed into the normal flame zone.

(8) Mass of previously produced controlled substances fed into a destruction unit. Each entity must measure the mass of each controlled substance that is fed into the destruction unit in more than trace concentrations. Such controlled substances include but are not limited to quantities that are shipped to the facility by another facility for destruction and quantities that are returned to the facility for reclamation but are found to be irretrievably contaminated and are therefore destroyed. The entity must use flowmeters, weigh scales, or a combination of volumetric and density measurements with an accuracy and precision of ±1 percent of full scale or better. If the measured mass includes more than trace concentrations of materials other than the controlled substance being destroyed, the entity must measure the concentration of the controlled substance being destroyed. The entity must multiply this concentration (mass fraction) by the mass measurement to obtain the mass of the controlled substance fed into the destruction unit.

(9) Emissions due to malfunctions of destruction unit. In their estimates of the mass of controlled substances destroyed, facilities that destroy controlled substances must account for any temporary reductions in the destruction efficiency that result from any malfunctions of the destruction unit, including periods of operation outside of the operating conditions defined in operating permit requirements and/or outside of the destruction unit's manufacturer's specifications.

(10) Emissions due to process startup, shutdown, or malfunctions. For each process listed in paragraph (b) of this section, each entity must account for emissions of controlled substance that occur at each facility as a result of startups, shutdowns, and malfunctions, either recording controlled substance emissions during these events, or documenting that these events do not result in significant controlled substance emissions. Facilities may use the calculation methods in paragraph (c)(1)(i) of this section to estimate emissions during startups, shutdowns, and malfunctions.

(11) Development of initial parameters. Initial scoping speciations, emissions testing, emission factor development, emission calculation factor development, emission characterization development, and destruction efficiency determinations must be completed by February 7, 2025, for processes and operating scenarios that operate between October 10, 2024, and November 12, 2024. For other processes and operating scenarios, initial scoping specifications, emissions testing, emission factor development, emission calculation factor development, emission characterization development, and destruction efficiency determinations must be complete by February 14 of the year following the year in which the process or operating scenario commences or recommences.

(12) Calibration for volumetric and density measurements. Calibrate all flow meters, weigh scales, and combinations of volumetric and density measures using monitoring instruments traceable to the International System of Units (SI) through the National Institute of Standards and Technology (NIST) or other recognized national measurement institute. Recalibrate all flow meters, weigh scales, and combinations of volumetric and density measures at the minimum frequency specified by the manufacturer. Use any of the following applicable flow meter test methods or the calibration procedures specified by the flow meter, weigh-scale, or other volumetric or density measure manufacturer.

(13) Calibration for concentration determinations. All analytical equipment used to determine the concentration of controlled substances, including but not limited to gas chromatographs and associated detectors, IR, FTIR, and NMR devices, must be calibrated at a frequency needed to support the type of analysis specified in the monitoring plan as required under paragraph (d)(5)(iii) of this section. Quality assurance samples at the concentrations of concern must be used for the calibration. Such quality assurance samples must consist of or be prepared from certified standards of the analytes of concern where available; if not available, calibration must be performed by a method specified in the monitoring plan.

(e) Data reporting requirements—(1) All facilities. In addition to the information required by § 82.13, for class I controlled substances, and § 82.24, for class II controlled substances, each entity must report the information in paragraphs (e)(1)(ii) through (iv) of this section according to the schedule in paragraph (e)(1)(i) of this section.

[79 FR 64288, Oct. 28, 2014]

This appendix is based on information provided by the Ozone Secretariat of the United Nations Ozone Environment Programme.** The Appendix lists available U.S. harmonized tariff schedule codes identifying headings and subheadings for Annex D products that may contain controlled substances.

** “A Note Regarding the Harmonized System Code Numbers for the Products Listed in Annex D.” Adopted by Decision IV/15 paragraph 3, of the Fourth Meeting of the Parties in Copenhagen, 23-25 November, 1992.

The Harmonized Tariff Schedule of the United States uses an enumeration system to identify products imported and exported to and from the U.S. This system relies on a four digit heading, a four digit subheading and additional two digit statistical suffix to characterize products. The United States uses the suffix for its own statistical records and analyses. This Appendix lists only headings and subheadings.

While some can be readily associated with harmonized system codes, many products cannot be tied to HS classifications unless their exact composition and the presentation are known. It should be noted that the specified HS classifications represent the most likely headings and subheadings which may contain substances controlled by the Montreal Protocol. The codes given should only be used as a starting point; further verfication is needed to ascertain whether or not the products actually contain controlled substances.

Category 1. Automobile and Truck Air Conditioning Units (whether incorporated in vehicles or not)

There are no separate code numbers for air conditioning units specially used in automobiles and trucks. Although a code has been proposed for car air conditioners, it is not yet officially listed in the Harmonized Tariff Schedule (see category 2). The following codes apply to the vehicles potentially containing air conditioning units.

Category 2. Domestic and Commercial Refrigeration and Air Conditioning/Heat Pump Equipment

Domestic and commercial air conditioning and refrigeration equipment fall primarily under headings 8415 and 8418.

Category 3. Aerosol Products

An array of different products use controlled substances as aerosols and in aerosol applications. Not all aerosol applications use controlled substances, however. The codes given below represent the most likely classifications for products containing controlled substances. The product codes listed include **** :

**** Other categories of products that may contain controlled substances are listed below. EPA is currently working to match them with appropriate codes. They include: coatings and electronic equipment (e.g., electrical motors), coatings or cleaning fluids for aircraft maintenance, mold release agents (e.g. for production of plastic or elastomeric materials), water and oil repellant (potentially under HS 3402), spray undercoats (potentially under “paints and varnishes”), spot removers, brake cleaners, safety sprays (e.g., mace cans), animal repellant, noise horns (e.g., for use on boats), weld inspection developers, freezants, gum removers, intruder alarms, tire inflators, dusters (for electronic and non-electronic applications), spray shoe polish, and suede protectors.

• varnishes • perfumes • preparations for use on hair • preparations for oral and dental hygiene • shaving preparations • personal deodorants, bath preparations • prepared room deodorizers • soaps • lubricants • polishes and creams • explosives • insecticides, fungicides, herbicides, disinfectants • arms and ammunition • household products such as footwear or leather polishes • other miscellaneous products Category 4. Portable Fire Extinguishers Category 5. Insulation Boards, Panels and Pipe Covers

These goods have to be classified according to their composition and presentation. For example, if the insulation materials are made of polyurethane, polystyrene, polyolefin and phenolic plastics, then they may be classified Chapter 39, for “Plastics and articles thereof”. The exact description of the products at issue is necessary before a classification can be given. ******

****** This category may include insulating board for building panels and windows and doors. It also includes rigid appliance insulation for pipes, tanks, trucks, trailers, containers, train cars & ships, refrigerators, freezers, beverage vending machines, bulk beverage dispensers, water coolers and heaters and ice machines.

Category 6. Pre-Polymers

According to the Explanatory Notes to the Harmonized Commodity Description and Coding System, “prepolymers are products which are characterized by some repetition of monomer units although they may contain unreacted monomers. Prepolymers are not normally used as such but are intended to be transformed into higher molecular weight polymers by further polymerization. Therefore the term does not cover finished products, such as di-isobutylenes or mixed polyethylene glycols with very low molecular weight. Examples are epoxides based with epichlorohydrin, and polymeric isocyanates.”

Parties operating under Article 5 of the Montreal Protocol as of March 26, 2014 are listed below. An updated list can be located at: http://ozone.unep.org/new_site/en/parties_under_article5_para1.php.
