(a) Applicability. The provisions of this section apply to the following conditions of use of carbon tetrachloride, including manufacturing and processing for export, except to the extent the conditions of use are prohibited by § 751.705:
(1) Domestic manufacture, except where carbon tetrachloride is manufactured solely as a byproduct.
(2) Import.
(3) Processing as a reactant in the production of hydrochlorofluorocarbons, hydrofluorocarbons, hydrofluoroolefins and perchloroethylene.
(4) Processing: Incorporation into formulation, mixture, or reaction products for agricultural products manufacturing, vinyl chloride manufacturing, and other basic organic and inorganic chemical manufacturing.
(5) Processing: Repackaging for use as a laboratory chemical.
(6) Processing: Recycling.
(7) Industrial and commercial use as an industrial processing aid in the manufacture of agricultural products and vinyl chloride.
(8) Industrial and commercial use in the elimination of nitrogen trichloride in the production of chlorine and caustic soda and the recovery of chlorine in tail gas from the production of chlorine.
(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.
| 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. Prior monitoring data cannot be used to meet this requirement.
(v) Observation of monitoring. (A) Owners and operators must provide potentially exposed persons or their designated representatives an opportunity to observe any monitoring of occupational exposure to CTC that is conducted under this section and designed to characterize their exposure.
(B) When monitoring observation requires entry into a regulated area, the owner or operator must provide the observers with the required PPE.
(C) Only persons who are authorized to have access to facilities classified in the interest of national security must be permitted to observe exposure monitoring conducted in such facilities.
(vi) Notification of monitoring results. (A) The owner or operator must inform each person whose exposures are monitored or who is part of a monitored exposure group and their designated representatives of any monitoring results within 15 working days of receipt of those monitoring results.
(B) This notification must include the following:
(1) Exposure monitoring results;
(2) Identification and explanation of the ECEL and ECEL action level;
(3) Statement of whether the monitored airborne concentration of carbon tetrachloride exceeds the ECEL action level or ECEL;
(4) If the ECEL is exceeded, descriptions of any exposure controls implemented by the owner or operator to reduce exposures to or below the ECEL, as required by paragraph (d)(1) of this section;
(5) Explanation of any required respiratory protection provided in accordance with paragraphs (b)(3)(iv), (d)(1)(i), and (f) of this section;
(6) Quantity of carbon tetrachloride in use at the time of monitoring;
(7) Location of carbon tetrachloride use at the time of monitoring;
(8) Manner of carbon tetrachloride use at the time of monitoring; and
(9) Identified releases of carbon tetrachloride;
(C) Notice must be written in plain language and either provided to each potentially exposed person and their designated representatives individually in a language that the person understands, or posted in an appropriate and accessible location outside the regulated area with an English-language version and a non-English language version representing the language of the largest group of workers who do not read English.
(3) Regulated areas—(i) Establishment. By September 20, 2027 for Federal agencies and Federal contractors acting for or on behalf of the Federal government, or by September 9, 2026 for non-Federal owners and operators, or within three months after receipt of any exposure monitoring that indicates exposures exceeding the ECEL, the owner or operator must establish and maintain a regulated area wherever airborne concentrations of carbon tetrachloride exceeds or can reasonably be expected to exceed the ECEL.
(ii) Access. The owner or operator must limit access to regulated areas to authorized persons.
(iii) Demarcation. The owner or operator must demarcate regulated areas from the rest of the workplace in a manner that adequately establishes and alerts persons to the boundaries of the area and minimizes the number of authorized persons exposed to carbon tetrachloride within the regulated area.
(iv) Provisions of respirators. (A) The owner or operator must ensure that each person who enters a regulated area is supplied with a respirator selected in accordance with paragraph (f) of this section and must ensure that all persons within the regulated area are using the provided respirators whenever carbon tetrachloride exposures may exceed the ECEL.
(B) An owner or operator who has implemented all feasible controls as required in paragraph (d)(1)(i) of this section, and who has established a regulated area as required by paragraph (b)(3)(i) of this section where carbon tetrachloride exposure can be reliably predicted to exceed the ECEL only on certain days (for example, because of work or process schedule) must have persons use respirators in that regulated area on those days.
(v) Prohibited activities. (A) The owner or operator must ensure that, within a regulated area, persons do not engage in non-work activities which may increase CTC exposure.
(B) The owner or operator must ensure that while persons are wearing respirators in the regulated area, they do not engage in activities which interfere with respirator performance.
(c) Direct dermal contact controls (DDCC). Beginning September 20, 2027 for Federal agencies or Federal contractors acting for or on behalf of the Federal government, or by June 16, 2025 for non-Federal owners and operators, or within 30 days of introduction of carbon tetrachloride into the workplace, whichever is later, owners or operators must ensure that all persons are separated, distanced, physically removed, or isolated to prevent direct dermal contact with carbon tetrachloride or from contact with equipment or materials on which carbon tetrachloride may exist consistent with the requirements of paragraph (d)(1)(ii) of this section and, if necessary, paragraph (f) of this section.
(d) Exposure control procedures and plan—(1) Methods of compliance—(i) ECEL.

(B) If the feasible controls required under paragraph (d)(1)(i)(A) of this section that can be instituted do not reduce exposures for potentially exposed persons to or below the ECEL, then the owner or operator must use such controls to reduce exposure to the lowest levels achievable by these controls and must supplement those controls with the use of respiratory protection that complies with the requirements of paragraph (f) of this section.
(C) Where an owner or operator cannot demonstrate exposure to carbon tetrachloride has been reduced to or below the ECEL through the use of controls required under paragraphs (d)(1)(i)(A) and (B) of this section, and has not demonstrated that it has appropriately supplemented with respiratory protection that complies with the requirements of paragraph (f) of this section, this will constitute a failure to comply with the ECEL.
(D) The owner or operator must ensure that any engineering controls instituted under paragraph (d)(1)(i)(A) of this section do not increase emissions of carbon tetrachloride to ambient air outside the workplace.
(ii) Direct dermal contact controls (DDCC). (A) The owner or operator must institute one or a combination of elimination, substitution, engineering controls, or administrative controls to prevent all persons from direct dermal contact with carbon tetrachloride except to the extent that the owner or operator can demonstrate that such controls are not feasible.
(B) If the feasible controls required under paragraph (d)(1)(ii)(A) of this section that can be instituted do not prevent direct dermal contact with carbon tetrachloride, then the owner or operator must use such controls to reduce direct dermal contact to the extent achievable by these controls and must supplement those controls by the use of dermal protection that complies with the requirements of paragraph (f) of this section.
(C) Where an owner or operator cannot demonstrate that direct dermal contact to carbon tetrachloride is prevented through the use of controls required under paragraphs (d)(1)(ii)(A) and (B) of this section, and has not demonstrated that it has appropriately supplemented with dermal protection that complies with the requirements of paragraph (f) of this section, this will constitute a failure to comply with the DDCC requirements.
