SUPPLEMENTARY INFORMATION:

This is a proposed extension of the ICR, which is currently approved through October 31, 2026. An agency may not conduct or 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 February 24, 2026 during a 60-day comment period (91 FR 8872). 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, Room 3334, 1301 Constitution Ave. NW, Washington, DC. The telephone number for the Docket Center is 202-566-1744. For additional information about EPA's public docket, visit www.epa.gov/​dockets.

Abstract: This information collection request (ICR) addresses the paperwork requirements contained in the current Chemical Data Reporting (CDR) rule ( 40 CFR part 711) under the Toxic Substances Control Act (TSCA). Under TSCA section 8(a) (15 U.S.C. 2607), the Environmental Protection Agency (EPA) is authorized to collect certain information on chemical substances manufactured (including imported) or processed in the United States. The CDR was formerly known as the Inventory Update Rule (IUR).

The CDR collection provides chemical manufacture, processing, and use information that helps EPA identify chemicals to which the public may be exposed as consumers or as workers in commercial and industrial settings. The data also helps EPA assess routes of potential exposure to those chemicals. The CDR data collection is on a four-year reporting cycle and contains detailed manufacturing, processing, and use information drawn from the principal reporting year; as well as basic information on production volume, by ( printed page 68132) year, for the three years prior to the principal reporting year. The next CDR collection will occur in 2028; there are no changes to the reporting requirements.

The ICR, which is available in the docket along with other related materials, provides a detailed explanation of the collection activities and the burden estimate that is only briefly summarized here:

Form Number: 9600-010.

Respondents/affected entities: Entities potentially affected by this ICR include companies manufacturing (including importing) certain chemical substances listed on the TSCA Inventory and regulated under TSCA section 8(a) CDR regulation. North American Industrial Classification System (NAICS) codes are identified in question 12 of the ICR.

Respondent's obligation to respond: Mandatory. 15 U.S.C. 2607; 40 CFR part 711.

Estimated number of respondents: 5,238 (total).

Frequency of response: Once every four years.

Total estimated burden: 891,053 hours (per year). Burden is defined at 5 CFR 1320.03(b).

Total estimated cost: $92,127,597 (per year), which includes $0 annualized capital or operation & maintenance costs.

Changes in the estimates: This ICR includes an increase of 161,568 hours in the total estimated burden compared with that currently approved by OMB. The increase reflects the use of 2020 CDR data (rather than 2016 CDR used for the previous ICR update) for estimating the reporting universe. Although in 2020 fewer sites reported to CDR than in 2016 ( i.e., fewer Form Us submitted), on average the sites reported a greater number of chemicals. In 2020 CDR, there were 5,238 sites reporting on 8.3 chemicals per report as opposed to 5,460 sites and 7.38 chemicals per report in 2016 CDR. This change resulted in a substantial increase in the number of chemical reports submitted. In addition, fewer chemical reports were for partially exempted chemicals (see 40 CFR 711.6 for a list of chemicals that are partially exempted from reporting under CDR). In 2016 CDR, approximately 21% of reports were partial reports, whereas in 2020 CDR the share of partial reports was about 7%. The average burden for each chemical report is higher because a greater percentage of the chemical reports are full reports. This change is an adjustment.
