SUPPLEMENTARY INFORMATION:

This is a proposed extension of the ICR, which is currently approved through September 30, 2023. An agency may neither conduct nor sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number.

Public comments were previously requested via the Federal Register on July 22, 2022 during a 60-day comment period (87 FR 43843). This notice allows for an additional 30-days for public comments. Supporting documents, which explain in detail the information that the EPA will be collecting, are available in the public docket for this ICR. The docket can be viewed online at www.regulations.gov, or in person at the EPA Docket Center, WJC West Building, Room 3334, 1301 Constitution Ave. NW, Washington, DC.

Abstract: The New Source Performance Standards (NSPS) for Kraft Pulp Mill Affected Sources for Which Construction, Reconstruction, or Modification Commenced After May 23, 2013 (40 CFR part 60, subpart BBa) were proposed on May 23, 2013; promulgated on April 4, 2014; and amended on November 5, 2020. These regulations apply to emissions of particulate matter (PM) and total reduced sulfur (TRS) at recovery furnaces, smelt dissolving tanks (SDTs), lime kilns, digester systems, brown stock washer (BSW) systems, multiple effect evaporator systems and condensate stripper systems at kraft pulp mills that commenced construction, or modification or reconstruction after May 23, 2013. At pulp mills, where kraft pulping is combined with neutral sulfite semi-chemical pulping, the provisions of this subpart are applicable when any portion of the material charged to an affected source is produced by the kraft pulping operation. This subpart includes provisions specifying that sources complying with the TRS standard for digester systems, BSW systems, evaporator systems and condensate stripper systems by venting to a control device must collect the gases in a closed-vent system subject to the provisions of 40 CFR part 63, subpart S. Facilities may be exempt from the TRS standard in the NSPS if the facility can demonstrate that TRS emissions from a brown stock washer cannot feasibly be controlled either technically or economically. New facilities include those that commenced construction, modification or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR part 60, subpart BBa.

In general, all NSPS standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NSPS.

Form Numbers: None.

Respondents/affected entities: Kraft pulp mills.

Respondent's obligation to respond: Mandatory (40 CFR part 60, subpart BBa).

Estimated number of respondents: 12 (total).

Frequency of response: Initially, occasionally, and semiannually.

Total estimated burden: 4,250 hours (per year). Burden is defined at 5 CFR 1320.3(b).

Total estimated cost: $1,000,000 (per year), which includes $487,000 in annualized capital/startup and/or operation & maintenance costs.

Changes in the Estimates: There is an adjustment decrease in the total estimated burden as currently identified in the OMB Inventory of Approved Burdens. due to an update of the respondent count. The previous ICR renewal assumed 12 existing sources and two new sources per year would be subject to these requirements. However, consultations with the Agency's industry experts estimate there are 12 existing sources and no new sources per year. The previous ICR reflected those burdens and costs associated with the initial activities for subject facilities. This includes purchasing monitoring equipment, conducting performance tests and establishing recordkeeping systems. This ICR, by in large, reflects the on-going burden and costs for existing facilities. Activities for existing source include continuously monitoring of pollutants and the submission of semiannual reports. In addition, there are no new facilities that are expected to be in the initial compliance phase described above. The overall result is a decrease in burden hours and costs. There is also a decrease in the Capital and O&M costs from the most-recently approved ICR due to the updated respondent count.
