Section 721.532 - 1-Butanol, 3-methoxy-3-methyl-, acetate(a)Chemical substance and significant new uses subject to reporting.(1) The chemical substance identified as 1-butanol, 3-methoxy-3-methyl-, acetate (PMN P-00-618; SNUN S-05-03; and SNUN S-11-4; CAS No. 103429-90-9) is subject to reporting under this section for the significant new uses described in paragraphs (a)(2) and (a)(3) of this section.(2) The significant new uses are:(i)Industrial, commercial, and consumer activities. Requirements as specified in § 721.80 . The significant new use is any use other than the use described in P-00-618.(3) The significant new uses for any use other than the use described in P-00-618: (i)Protection in the workplace. Requirements as specified in § 721.63(a)(1), (a)(3)(i), (b) (concentration set at 0.1 percent), and (c). When determining which persons are reasonably likely to be exposed as required for § 721.63(a)(1) engineering control measures (e.g., enclosure or confinement of the operation, general and local ventilation) or administrative control measures (e.g., workplace policies and procedures) shall be considered and implemented to prevent exposure, where feasible. Butyl rubber gloves with a minimum thickness of 16.6 mils or Silver shield gloves with a minimum thickness of 2.7 mils have been tested in accordance with the American Society for Testing Materials (ASTM) F739 method and found by EPA to satisfy the consent orders and § 721.63(a)(2)(i) requirements for dermal protection to 100 percent chemical substance. Silver Shield gloves with a minimum thickness of 2.7 mils have been tested in accordance with the American Society for Testing Materials (ASTM) F739 method and found by EPA to satisfy the consent orders and § 721.63(a)(2)(i) requirements for dermal protection for paint formulations where concentrations of the chemical substance is 10% or less. Gloves and other dermal protection may not be used for a time period longer than they are actually tested and must be replaced at the end of each work shift.(ii)Hazard communication program. Requirements as specified in § 721.72(a), (b) (concentration set at 0.1 percent), (c), (d), (f), (g)(1)(iv), (g)(1)(iv), (g)(2)(i), (g)(2)(ii), (g)(2)(iii), (g)(2)(v), (g)(2)(v), and (g)(5).(iii)Industrial, commercial, and consumer activities. Requirements as specified in § 721.80(f), (o) , and any application method that generates a vapor, mist, or aerosol when the percent concentration of the SNUN substance in the final product exceeds 10%.(b)Specific requirements. The provisions of subpart A of this part apply to this section except as modified by this paragraph. (1)Recordkeeping. Recordkeeping requirements as specified in § 721.125(a) through (i) are applicable to manufacturers and processors of this substance.(2)Limitations or revocation of certain notification requirements.
