(9) Disposal.
(b) Existing chemical exposure limit (ECEL)—(1) Eight-hour time-weighted average (TWA) ECEL. Beginning September 20, 2027 for Federal agencies or Federal contractors acting for or on behalf of the Federal government, or by September 9, 2026 for non-Federal owners and operators, or beginning four months after introduction of carbon tetrachloride into the workplace if carbon tetrachloride commences after June 11, 2026, the owner or operator must ensure that no person is exposed to an airborne concentration of carbon tetrachloride in excess of the ECEL, consistent with the requirements of paragraph (d)(1)(i) of this section and, if necessary, paragraph (f) of this section.
(2) Exposure monitoring—(i) General. (A) Owners or operators must determine each potentially exposed person's exposure, without regard to respiratory protection, by either:
(1) Taking a personal breathing zone air sample of each potentially exposed person's exposure; or
(2) Taking personal breathing zone air samples that are representative of the 8-hour TWA of each exposure group.
(B) Personal breathing zone air samples are representative of the 8-hour TWA of all potentially exposed persons in an exposure group if the samples are of at least one person's full-shift exposure who represents the highest potential carbon tetrachloride exposures in that exposure group. Personal breathing zone air samples taken during one work shift may be used to represent potentially exposed person exposures on other work shifts where the owner or operator can document that the tasks performed and conditions in the workplace are similar across shifts.
(C) Exposure samples must be analyzed using an appropriate analytical method by a laboratory that complies with the Good Laboratory Practice Standards in 40 CFR part 792 or a laboratory accredited by the American Industrial Hygiene Association (AIHA) or another industry-recognized program.
(D) Owners or operators must ensure that methods used to perform exposure monitoring produce results that are accurate, to a confidence level of 95 percent, to within plus or minus 25 percent for airborne concentrations of carbon tetrachloride.
(E) Owners and operators must re-monitor within 15 working days after receipt of any exposure monitoring when results indicate non-detect, unless an Environmental Professional as defined at 40 CFR 312.10 or a Certified Industrial Hygienist reviews the exposure monitoring results and determines re-monitoring is not necessary.
(ii) Initial monitoring. By June 21, 2027 for Federal agencies and Federal contractors acting for or on behalf of the Federal government, or by June 11, 2026 for non-Federal owners and operators, or within 30 days of introduction of carbon tetrachloride into the workplace, whichever is later, each owner or operator covered by this section must perform initial monitoring of potentially exposed persons. Where the owner or operator has monitoring results from monitoring conducted within five years prior to February 18, 2025 and the monitoring satisfies all other requirements of this section, the owner or operator may rely on such earlier monitoring results to satisfy the requirements of this paragraph (b)(2)(ii).
(iii) Periodic monitoring. The owner or operator must establish an exposure monitoring program for periodic monitoring of exposure to carbon tetrachloride in accordance with Table 1.
Table 1 to § 751.707(b)(3)(iii)—Periodic Monitoring Requirements
| Air concentration condition
| Periodic exposure monitoring requirement
|
|---|
| If all initial exposure monitoring is below the ECEL action level (<0.02 ppm 8-hour TWA) | Periodic exposure monitoring is required at least once every five years.
|
| If the most recent exposure monitoring indicates that airborne exposure is above the ECEL (> 0.03 ppm 8-hour TWA) | Periodic exposure monitoring is required within three months of the most recent exposure monitoring.
|
| If the most recent exposure monitoring indicates that airborne exposure is at or above the ECEL action level but at or below the ECEL (≥0.02 ppm 8-hour TWA, ≤0.03 ppm 8-hour TWA) | Periodic exposure monitoring is required within six months of the most recent exposure monitoring.
|
| If the two most recent (non-initial) exposure monitoring measurements, taken at least seven days apart within a 6-month period, indicate exposure is below the ECEL action level (<0.02 ppm 8-hour TWA) | Periodic exposure monitoring is required within five years of the most recent exposure monitoring.
|
| If the owner or operator engages in a condition of use for which WCPP ECEL would be required but does not manufacture, process, use, or dispose of carbon tetrachloride in that condition of use over the entirety of time since the last required monitoring event | The owner or operator may forgo the next periodic exposure monitoring event. However, documentation of cessation of use of carbon tetrachloride is required; and periodic monitoring would be required when the owner or operator resumes the condition of use. |
(iv) Additional exposure monitoring. (A) The owner or operator must conduct additional exposure monitoring within a reasonable timeframe whenever there has been a change in the production, process, control equipment, personnel or work practices that may reasonably be expected to result in new or additional exposures above the ECEL or when the owner or operator has any reason to believe that new or additional exposures above the ECEL action level have occurred.
(B) Whenever start-ups or shutdowns, or ruptures, malfunctions or other breakdowns or unexpected releases occur that may lead to exposure to potentially exposed persons, the owner or operator must conduct the additional exposure monitoring within a reasonable timeframe after the conclusion of the start-up or shutdown and/or the cleanup, repair or remedial action of the malfunction or other breakdown or unexpected release.

(ii) Dermal protection used by each potentially exposed person and PPE program implementation as described in § 751.707(f)(3), including:
(A) The name, workplace address, work shift, job classification, and work area of each person reasonably likely to directly handle carbon tetrachloride or handle equipment or materials on which carbon tetrachloride may be present and the type of PPE selected to be worn by each of these persons;
(B) The basis for specific PPE selection (e.g., demonstration based on permeation testing or manufacturer specifications that each item of PPE selected provides an impervious barrier to prevent exposure during expected duration and conditions of exposure, including the likely combinations of chemical substances to which the PPE may be exposed in the work area);
(C) Appropriately sized PPE and training on proper application, wear, and removal of PPE, and proper care/disposal of PPE;
(D) Occurrence and duration of any direct dermal contact with carbon tetrachloride that occurs during any activity or malfunction at the workplace that causes direct dermal exposures to occur and/or glove breakthrough, and corrective actions to be taken during and immediately following that activity or malfunction to prevent direct dermal contact to carbon tetrachloride; and
(E) Training in accordance with § 751.707(f)(3).
(iii) Information and training provided as required in § 751.707(e).
(4) Workplace participation. Owners or operators must document the notice to and ability of any potentially exposed person that may reasonably be affected by carbon tetrachloride inhalation exposure or direct dermal contact and their designated representatives to readily access the exposure control plans, facility exposure monitoring records, PPE program implementation records, or any other information relevant to carbon tetrachloride exposure in the workplace.
(c) Workplace requirements for laboratory use compliance. Owners and operators subject to the laboratory chemical requirements described in § 751.709 must retain records of:
(1) Dermal protection used by each potentially exposed person and PPE program implementation, as described in § 751.713(b)(3)(ii); and
(2) Documentation identifying criteria that the owner or operator will use to determine and implement control measures to reduce potentially exposed persons' exposure to carbon tetrachloride including laboratory ventilation devices;
(3) Documentation identifying: implementation of a properly functioning laboratory ventilation devices using manufacturer's instructions for installation, use, and maintenance of the devices including inspections, tests, development of maintenance procedures, the establishment of criteria for acceptable test results, and documentation of test and inspection results, except for the U.S. Department of Defense's use of carbon tetrachloride as a laboratory chemical in chemical weapons destruction; and
(4) For the U.S. Department of Defense's use of carbon tetrachloride as a laboratory chemical in chemical weapons destruction, documentation identifying implementation of advanced engineering controls that are in use and functioning properly and specific measures taken to ensure proper and adequate performance.
(d) Retention. Owners or operators must retain the records required under this section for a period of five years from the date that such records were generated.
