What This Subpart Covers
§ 63.5480 - What is the purpose of this subpart?
This subpart establishes emission limits, operating limits, and work practice standards for hazardous air pollutants (HAP) emitted from cellulose products manufacturing operations. Carbon disulfide, carbonyl sulfide, ethylene oxide, methanol, methyl chloride, propylene oxide, and toluene are the HAP emitted in the greatest quantities from cellulose products manufacturing operations. This subpart also establishes requirements to demonstrate initial and continuous compliance with the emission limits, operating limits, and work practice standards.
§ 63.5485 - Am I subject to this subpart?
You are subject to this subpart if you own or operate a cellulose products manufacturing operation that is located at a major source of HAP emissions.
(a) Cellulose products manufacturing includes both the Miscellaneous Viscose Processes source category and the Cellulose Ethers Production source category. The Miscellaneous Viscose Processes source category includes all of the operations that use the viscose process. These operations include the cellulose food casing, rayon, cellulosic sponge, and cellophane operations, as defined in § 63.5610. The Cellulose Ethers Production source category includes all of the cellulose ether operations, as defined in § 63.5610, that use the cellulose ether process.
(b) A major source of HAP is any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit any single HAP at a rate of 9.1 megagrams per year (Mg/yr) (10 tons per year (tpy)) or more or any combination of HAP at a rate of 23 Mg/yr (25 tpy) or more.
(c) The provisions of this subpart do not apply to research and development facilities, as defined in section 112(b)(7) of the Clean Air Act (CAA), regardless of whether the facilities are located at the same plant site as an operation subject to the provisions of this subpart.

This includes periods of startup, shutdown, and malfunction. These instances are deviations from the emission limits, operating limits, and work practice standards in this subpart. These deviations must be reported according to the requirements in § 63.5580.
(c) [Reserved]
(d) For each affected source that commenced construction or reconstruction before September 9, 2019, on or before December 29, 2020, deviations that occur during a period of startup, shutdown, or malfunction are not violations if you demonstrate to the Administrator's satisfaction that you were operating in accordance with § 63.5515(b). The Administrator will determine whether deviations that occur on or before December 29, 2020, and during a period you identify as a startup, shutdown, or malfunction are violations, according to the provisions in § 63.5515(b). This section no longer applies after December 30, 2020. For new sources that commence construction or reconstruction after September 9, 2019, this section does not apply.
§ 63.5560 - How do I monitor and collect data to demonstrate continuous compliance?
(a) You must monitor and collect data according to this section.
(b) Except for monitor malfunctions, associated repairs, and required quality assurance or control activities (including, as applicable, calibration checks and required zero and span adjustments), you must monitor continuously (or collect data at all required intervals) at all times that the affected source is operating, including periods of startup, shutdown, and malfunction.
(c) You may not use data recorded during monitoring malfunctions, associated repairs, required quality assurance or control activities, and periods of no flow for all or a portion of an affected source in data averages and calculations used to report emission or operating levels, nor may such data be used in fulfilling a minimum data availability requirement, if applicable. You must use all the data collected during all other periods in assessing the operation of the control device and associated control system.
(d) All terms in this subpart that define a period of time for completing required tasks (e.g., weekly, monthly, quarterly, or annually) refer to the standard calendar periods.
(1) You may change time periods specified in this subpart for completing required tasks by mutual agreement with the Administrator, as specified in subpart A of this part. For example, a period could begin on the compliance date or another date, rather than on the first day of the standard calendar period. For each time period that is changed by agreement, the revised period must remain in effect until it is changed. A new request is not necessary for each recurring period.
(2) Where the period specified for compliance is a standard calendar period, if the initial compliance date occurs after the beginning of the period, then you must comply according to the schedule specified in paragraph (d)(2)(i) or (ii) of this section, as appropriate.
(i) You must comply before the end of the standard calendar period within which the compliance deadline occurs, if there remain at least 3 days for tasks that must be performed weekly, at least 2 weeks for tasks that must be performed monthly, at least 1 month for tasks that must be performed quarterly, or at least 3 months for tasks that must be performed annually; or
(ii) In all instances where a provision of this subpart requires completing a task during each of multiple successive periods, you may perform the required task at any time during the specified period, provided that the task is conducted at a reasonable interval after completion of the task during the previous period.

If you submit a compliance report according to Table 8 to this subpart along with, or as part of, the semiannual monitoring report required by 40 CFR 70.6(a)(3)(iii)(A) or 40 CFR 71.6(a)(3)(iii)(A), and the compliance report includes all required information concerning deviations from any emission limit, operating limit, or work practice standard in this subpart, then submitting the compliance report will satisfy any obligation to report the same deviations in the semiannual monitoring report. However, submitting a compliance report will not otherwise affect any obligation you may have to report deviations from permit requirements to the permit authority.
