Title 40: Protection of Environment
PART 63—NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES (CONTINUED)
Subpart UUUU—National Emission Standards for Hazardous Air Pollutants for Cellulose Products Manufacturing


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.

(d) For cellulose ether operations, the applicability provisions in paragraph (d)(1) or (2) of this section apply.

(1) The applicability provisions in §§63.100(a) through (f) and 63.160 apply if you are complying with the equipment leak provisions of subpart H of this part.

(2) The applicability provisions in §63.1019 apply if you are complying with the equipment leak provisions in subpart UU of this part.

(e) For cellulose ether operations, the applicability provisions in §§63.100(a) through (f) and 63.110(a), (e) and (h) apply if you are complying with the wastewater provisions in subparts F and G of this part.

§63.5490   What parts of my plant does this subpart cover?

(a) This subpart applies to each new, reconstructed, or existing affected source for the Miscellaneous Viscose Processes and Cellulose Ethers Production source categories.

(b) The affected source for the Miscellaneous Viscose Processes source category is each cellulose food casing, rayon, cellulosic sponge, or cellophane operation, as defined in §63.5610. The affected source for the Cellulose Ethers Production source category is each cellulose ether operation, as defined in §63.5610.

(c) You must consider storage vessels to be part of your process unit, as defined in §63.5610, under either of the conditions described in paragraphs (c)(1) and (2) of this section. Otherwise, you may assign your storage vessels according to paragraph (c)(3) or (4) of this section.

(1) The input to the storage vessel from your viscose process or cellulose ether process (either directly or through other storage vessels assigned to your process unit) is greater than or equal to the input from any other process.

(2) The output from the storage vessel to your viscose process or cellulose ether process (either directly or through other storage vessels assigned to your process unit) is greater than or equal to the output to any other process.

(3) If the greatest input to and/or output from a shared storage vessel is the same for two or more processes, including at least one viscose process or cellulose ether process, you may assign the storage vessel to any process unit that has the greatest input or output.

(4) If the use varies from year to year, then you must base the determination on the utilization that occurred during the year preceding June 11, 2002 or, if the storage vessel was not operating during that year, you must base the use on the expected use for the first 5-year period after startup. You must include this determination in the Notification of Compliance Status Report specified in Table 7 to this subpart.

(d) An affected source is a new affected source if you began construction of the affected source after August 28, 2000 and you met the applicability criteria in §63.5485 at the time you began construction.

(e) An affected source is reconstructed if you meet the criteria as defined in §63.2.

(f) An affected source is existing if it is not new or reconstructed.

(g) For the purposes of this subpart, the definitions of new and existing affected source in paragraphs (d) through (f) of this section supersede the definitions of new and existing affected source in subparts F, G, H, U and UU of this part.

§63.5495   When do I have to comply with this subpart?

(a) If you have a new or reconstructed affected source, then you must comply with this subpart according to the requirements in paragraphs (a)(1) and (2) of this section.

(1) If you start up your affected source before June 11, 2002, then you must comply with the emission limits, operating limits, and work practice standards for new and reconstructed sources in this subpart no later than June 11, 2002.

(2) If you start up your affected source after June 11, 2002, then you must comply with the emission limits, operating limits, and work practice standards for new and reconstructed sources in this subpart upon startup of your affected source.

(b) If you have an existing affected source, then you must comply with this subpart according to the requirements in paragraphs (b)(1) and (2) of this section.

(1) Cellulose food casing, cellulosic sponge, cellophane, and cellulose ether operations must comply with the emission limits, operating limits, and work practice standards for existing sources in this subpart no later than June 13, 2005.

(2) Rayon operations must comply with this subpart according to the requirements in paragraphs (b)(2)(i) through (iii) of this section.

(i) Rayon operations must comply with the 35 percent reduction emission limit and associated operating limits and work practice standards for existing sources in this subpart no later than June 13, 2005.

(ii) Rayon operations must comply with the work practice standard for carbon disulfide unloading and storage operations for existing sources in this subpart no later than June 13, 2005.

(iii) Rayon operations must comply with the 40 percent reduction emission limit and associated operating limits and work practice standards for existing sources in this subpart no later than June 11, 2010.

(c) If you have an area source that increases its emissions or its potential to emit so that it becomes a major source of HAP and an affected source subject to this subpart, then the requirements in paragraphs (c)(1) and (2) of this section apply.

(1) An area source that meets the criteria of a new affected source, as specified in §63.5490(d), or a reconstructed affected source, as specified in §63.5490(e), must be in compliance with this subpart upon becoming a major source.

(2) An area source that meets the criteria of an existing affected source, as specified in §63.5490(f), must be in compliance with this subpart no later than 3 years after it becomes a major source.

(d) You must meet the notification requirements in §63.5575 and in subpart A of this part. Some of the notifications must be submitted before you are required to comply with the emission limits, operating limits, and work practice standards in this subpart.

(e) For the purposes of this subpart, the compliance dates in this section supersede the compliance dates in subparts F, G, H, U and UU of this part.
