For subpart HH, we were able to estimate mean cost-to-sales ratios using the survey sample approach. We identified an estimated mean cost-to-sales ratio of 1.4% (CI 0.4% - 2.5%) in the first year and 0.9% (CI 0.2% - 1.6%) in subsequent years for the 1-99 employee size range. There were no entities for subpart HH in the 100-499 employees or 500+ employees size ranges estimated to have a cost-to-sales ratio of greater than one percent. Because there are only six estimated new reporters for subpart HH, the number of entities estimated to exceed a cost-to-sales ratio of one percent among these reporters is less than one.
Regardless, the proposed requirements for subpart HH were developed to minimize impacts to small entities. For example, the proposed revisions would revise the calculation and reporting requirements for subpart HH to adjust emission estimates based on surface monitoring assessments conducted under 40 CFR part 60 or part 62 rules. The proposed amendments would be required for facilities that already conduct monitoring in order to comply with the control requirements in the landfill NSPS, EG, and federal plan (40 CFR part 60, subpart WWW or XXX, 40 CFR part 60, subparts Cc or Cf, and 40 CFR part 62, subparts GGG and OOO). These facilities would not be required to conduct any additional monitoring, but would use their existing measurement data, as collected under the landfills NSPS, EG, or federal plan, to adjust their engineering calculations. Facilities that are not subject to the landfill NSPS, EG, or federal plan would use proposed lower gas collection efficiency values or could elect to monitor their landfill cover to adjust their reported methane emissions.
      In general, the 95 percent confidence intervals are narrow and indicate good precision, which is attributable to the large sample size of the survey. Tables 4-2 through 4-5 present the survey sample analysis results for subparts B, W, and HH.  Table 4-2 presents the total number of affected facilities, the estimated percent that are owned by a small entity (whether a business or government), and the estimated number of affected entities that are small, for subparts B, W, and HH.

Notes:
[a] The estimated percent owned by a small entity was based on a stratified random sample of 519 facilities for which small business status of the parent company could be determined in DemographicsNow.

      Table 4-3 presents the estimated mean CRR by parent entity size, for subparts B, W, and HH. The CRR is calculated separately, using the expected first-year costs and the expected subsequent-year costs. Notably, nearly all 95 percent CIs for the mean costs-to-sales ratio are less than 1 percent, both for the first-year costs and the subsequent-year costs. All facilities with parent companies larger than 99 employees have mean CRRs that are less than 0.05 percent, across all years and all examined subparts.

Notes:
[a] Number of employees corresponds to the size of the parent entity.
[b] Estimates for the number of facilities are scaled to the population of affected facilities.
[c] Subpart B excludes facilities that report only to subparts LL, MM, NN, OO, PP, QQ, UU, or VV.
[d] Confidence intervals expressed as 0.0% - 0.0% represent nonzero values that are less than 0.05 percent.

      As Table 4-5 shows, in all estimated scenarios, zero facilities with parent entities larger than 99 employees are expected to have a cost-to-sales ratio that exceeds 1 percent. Of the 7,840 facilities reporting to subpart B, approximately 16 facilities are expected to have a first-year cost-to-sales ratio exceeding 1 percent. Notably, this estimate (16) has a 95 percent CI that includes 0. In subsequent years, none of the facilities in subpart B are expected to incur a cost-to-sales ratio exceeding 1 percent. Of the 188 affected facilities reporting to subpart W, approximately 8 facilities are expected to have a cost-to-sales ratio that exceeds 1 percent, and this is true both for the initial and subsequent years. For subpart HH, fewer than 1 of the 6 affected facilities is expected to have a cost-to-sales ratio exceeding 1 percent both in the first year and the subsequent years following promulgation of the proposed rule.

4.3.3 Additional Small Entity Impacts Considered

      The proposed revisions to Table A - 1 to part 98 are anticipated to result in a very small change to the number of reporters under subparts DD (estimated to apply to two potential facilities), II (estimated to apply to two potential facilities, OO (estimated to apply to one potential facility), and TT (estimated to apply to two potential facilities). For the small subset of reporters potentially affected by the proposed revisions to Table A - 1 to part 98 under subparts DD, II, OO, and TT, the EPA lacked data on specific affected entities. Due to the lack of data on the specific facilities that could be affected by the proposed revisions and a smaller sample size for subparts DD, II, OO, and TT, we were unable to estimate mean costs-to-sales ratios or the number of total entities exceeding a cost-to-sales ratio of 1 percent for these subparts using the individual facility approach or survey sample approach. However, based on data collected in the survey sample, we identified one, two, five, and one facilities, respectively, in the 1-99 employee size range for subparts DD, II, OO, and TT, with a minimal number of these facilities (zero, one, two, and one, respectively) exceeding the cost-to-sales ratio of one percent based on initial year facility costs. However, due to the very small number of estimated new reporters under these subparts (DD  -  two potential facilities, II  -  two potential facilities, OO  -  one potential facility), and TT  -  two potential facilities), is unlikely that the subset of reporters potentially affected by the proposed revisions to Table A - 1 to part 98 are likely to fall into this population, especially if the affected facilities are already close to the reporting threshold. For these reasons, we do not anticipate the proposed revisions to Table A - 1 would have a significant regulatory burden on a substantial number of small entities subject to subparts DD, II, OO, or TT.
For the remaining reporters affected by proposed revisions in this supplemental impacts, the impacts from the proposed revisions include labor burden to update revised emissions estimation methodologies and to conduct reporting and recordkeeping. The proposed costs for these revisions, which affect subparts C, F, G, N, P, Y, AA, HH, OO, PP, and QQ, are less than $100 per reporter (see sections 2.4 and 2.5 of this document). Therefore, we do not anticipate the proposed revisions would have a significant regulatory burden on a substantial number of small entities in these subparts.
 4.4 Conclusions of Small Entity Impacts Analysis
Based on the results of the small business analyses, EPA has concluded that the proposed rule costs will have no significant regulatory burden for any directly regulated small entities and therefore would not have a significant economic impact on a substantial number of small entities.

Appendix A:  Revisions and Burden Impacts for Proposed Technical Revisions for the Greenhouse Gas Reporting Rule

This appendix describes the proposed revisions to each subpart and associated burden. Specifically, this appendix summarizes for each subpart that impact burden. Revisions to reporting requirements and revisions for which costs impacts or savings were estimated in sections 2.1 through 2.6 of the document "Assessment of Burden Impacts for Proposed Supplemental Notice Revisions for the Greenhouse Gas Reporting Rule" (hereafter "impacts assessment"). This section provides additional information on the proposed revisions for each subpart.
Labor rates. The associated labor costs were estimated for each of the amendments with quantifiable burden in sections 2.1 through 2.5 using updated labor rates from the Bureau of Labor Statistics (May $2021), with the exception of subpart W.

Sections 1.0 through 26.0 of this appendix provide a brief description of the proposed revisions and an explanation of the impact on burden.
Subpart A  -  General Provisions
EPA is proposing revisions to subpart A that would impact burden. Total burden and costs for subpart A changes are included in Table 3-1 of the impacts assessment.
Updates to Global Warming Potentials (GWPs). The proposed revisions would modify Table A-1 to subpart A of part 98. The proposed revisions to the General Provisions do not impact all GHGRP reporters, but only reporters in subparts where revisions to the GWPs in Table A-1 of part 98 would result in a change in the number of entities required to report under Part 98. The proposed revisions would affect subparts V, W, DD, HH, II, OO, and TT. The burden for these revisions was estimated as described in section 2.1 of the impacts assessment and is summarized in sections 9.0, 10.0, 13.0, 14.0, 15.0, 16.0, and 19.0 of this Appendix. Additional information may be found in Appendix B of this document.
Revisions to reporting or data entry requirements. The proposed revisions would add two data elements, shown in Table A-2 of this appendix. The burden for these revisions was estimated as described in section 2.5 of the impacts assessment. Additional information may be found in Appendix B of this document.

The EPA is proposing to revisions to 40 CFR 98.470 to clarify the applicability of the requirements with respect to reporters who may transition to reporting under proposed subpart VV. The proposed changes are a correction or clarification to the previously proposed requirements, and would not revise the costs estimated in the June 21, 2022 proposed rule.
 Subpart VV  -  Geologic Sequestration of Carbon Dioxide With Enhanced Oil Recovery Using ISO 27916
EPA is proposing no revisions to subpart VV that are expected to have an impact on burden, as described in section 2.6 of the impacts assessment. The EPA is re-proposing to sections 40 CFR 98.480 and 98.481 to clarify the applicability of the requirements with respect to reporters who may currently report under subparts RR or UU. The proposed changes are a correction or clarification to the previously proposed requirements, and would not revise the costs estimated in the June 21, 2022 proposed rule.
 Subpart WW  -  Coke Calciners
EPA is proposing to add a new subpart WW that would impact burden. The burden for these revisions was estimated as described in section 2.2 of the impacts assessment and shown in Table A-27 of this Appendix. Total burden and costs for subpart WW changes are included in Table 3-1 of the impacts assessment.

 Confidentiality Determinations
In addition to proposing revisions to streamline and improve implementation of the rule and to improve the quality and consistency data, EPA is proposing confidentiality determinations for new or substantially revised reporting data elements in subparts A, B, F, G, N, P, Y, AA, HH, OO, PP, QQ, WW, XX, YY, and ZZ. EPA is also proposing confidentiality determinations for two existing data elements in subpart A for which a confidentiality determination has not previously been proposed. The proposed confidentiality determinations do not affect the recordkeeping and reporting requirements, and therefore, would not affect the burden on reporters. Thus, no burden change was estimated for these determinations.

          Appendix C: Calculation of Weights for Small Entity Impacts

      This appendix describes how weights were calculated for the survey sample approach outlined in section 4.2 of this document.
      In general, weights are calculated from the selection probabilities used to draw the sample. A nonresponse adjustment was also applied to account for the fact that parent company information could not be determined in DemographicsNow for some of the sampled facilities. Accordingly, for each facility i in a given stratum s, the Agency calculated its survey weight wis from (a) the selection probability pselection,is of the facility being solicited for the sample, and (b) the response probability presponse,is of the facility having the requisite information in DemographicsNow to determine whether it is a small business:

wis=1pselection,is*1presponse,is#Equation 1

      The response probabilities (the second factor in Equation 1, above) were calculated for each stratum as the fraction of solicited facilities for which business size could be determined: presponseW=173/180=0.96 for facilities reporting to W and presponsenot W=346/385=0.90 for facilities not reporting to W.
