Applicability and Compliance Dates
§63.11414   Am I subject to this subpart?
(a) You are subject to this subpart if you own or operate an area source of hazardous air pollutant (HAP) emissions that meets the criteria in paragraph (a)(1) or (2) of this section.
(1) You own or operate a plant that produces flexible polyurethane foam or rebond foam as defined in §63.1292 of subpart III.
(2) You own or operate a flexible polyurethane foam fabrication facility, as defined in §63.11419.
(b) The provisions of this subpart apply to each new and existing affected source that meets the criteria listed in paragraphs (b)(1) through (4) of this section.
(1) A slabstock flexible polyurethane foam production affected source is the collection of all equipment and activities necessary to produce slabstock flexible polyurethane foam.
(2) A molded flexible polyurethane foam production affected source is the collection of all equipment and activities necessary to produce molded foam.
(3) A rebond foam production affected source is the collection of all equipment and activities necessary to produce rebond foam.
(4) A flexible polyurethane foam fabrication affected source is the collection of all equipment and activities at a flexible polyurethane foam fabrication facility where adhesives are used to bond foam to foam or other substrates. Equipment and activities at flexible polyurethane foam fabrication facilities which do not use adhesives to bond foam to foam or other substrates are not flexible polyurethane foam fabrication affected sources.
(c) An affected source is existing if you commenced construction or reconstruction of the affected source on or before April 4, 2007.
(d) An affected source is new if you commenced construction or reconstruction of the affected source after April 4, 2007.
(e) This subpart does not apply to research and development facilities, as defined in section 112(c)(7) of the Clean Air Act (CAA).
(f) You are exempt from the obligation to obtain a permit under 40 CFR part 70 or 40 CFR part 71, provided you are not otherwise required by law to obtain a permit under 40 CFR 70.3(a) or 40 CFR 71.3(a). Notwithstanding the previous sentence, you must continue to comply with the provisions of this subpart.
§63.11415   What are my compliance dates?
(a) If you own or operate an existing slabstock flexible polyurethane foam production affected source, you must achieve compliance with the applicable provisions in this subpart by July 16, 2008.
(b) If you own or operate an existing molded flexible polyurethane foam affected source, an existing rebond foam production affected sources, or an existing flexible polyurethane foam fabrication affected source, you must achieve compliance with the applicable provisions in this subpart by July 16, 2007.
(c) If you startup a new affected source on or before July 16, 2007, you must achieve compliance with the applicable provisions in this subpart not later than July 16, 2007.
(d) If you startup a new affected source after July 16, 2007, you must achieve compliance with the provisions in this subpart upon startup of your affected source.
Standards and Compliance Requirements
§63.11416   What are the standards for new and existing sources?
(a) If you own or operate a slabstock flexible polyurethane foam production affected source, you must meet the requirements in paragraph (b) of this section. If you own or operate a molded foam affected source, you must meet the requirements in paragraph (c) of this section. If you own or operate a rebond foam affected source, you must meet the requirements in paragraph (d) of this section. If you own or operate a flexible polyurethane foam fabrication affected source, you must meet the requirements in paragraph (e) of this section.
(b) If you own or operate a new or existing slabstock polyurethane foam production affected source, you must

 not use any material containing methylene chloride for any purpose in any slabstock flexible foam production process.
(c) If you own or operate a new or existing molded foam affected source, you must comply with the requirements in paragraphs (c)(1) and (2) of this section.
(1) You must not use a material containing methylene chloride as an equipment cleaner to flush the mixhead or use a material containing methylene chloride elsewhere as an equipment cleaner in a molded flexible polyurethane foam process.
(2) You must not use a mold release agent containing methylene chloride in a molded flexible polyurethane foam process.
(d) If you own or operate a new or existing rebond foam affected source, you must comply with the requirements in paragraphs (d)(1) and (2) of this section.
(1) You must not use a material containing methylene chloride as an equipment cleaner in a rebond foam process.
(2) You must not use a mold release agent containing methylene chloride in a rebond foam process.
(e) If you own or operate a new or existing flexible polyurethane foam fabrication affected source, you must not use any adhesive containing methylene chloride in a flexible polyurethane foam fabrication process.
(f) You may demonstrate compliance with the requirements in paragraphs (b) through (e) of this section using adhesive usage records, Material Safety Data Sheets, and engineering calculations.

§63.11417   What are the compliance requirements for new and existing sources?
(a) If you own or operate a slabstock flexible polyurethane foam production affected source, you must comply with the requirements in paragraph (b) of this section. If you own or operate a molded foam affected source, rebond foam affected source, or a loop slitter at a flexible polyurethane foam fabrication affected source you must comply with the requirements in paragraphs (c) and (d) of this section.
(b) Each owner or operator of a new or existing slabstock flexible polyurethane foam production affected source must comply with paragraphs (b)(2) and (3) of this section.
(1) [Reserved.]

(2) You must submit a notification of compliance status report no later than 180 days after your compliance date. The report must contain this certification of compliance, signed by a responsible official, for the standards in §63.11416(b): "This facility uses no material containing methylene chloride for any purpose on any slabstock flexible foam process."
(3) You must maintain records of the information used to demonstrate compliance, as required in §63.11416(f). You must maintain the records for 5 years, with the last 2 years of data retained on site. The remaining 3 years of data may be maintained off site.
