Federal Register / Vol. 86, No. 107 / Monday, June 7, 2021 / Rules and Regulations this SNUR are not expected to be significant or adversely impact a substantial number of small entities. In a SNUR that published in the Federal Register of June 2, 1997 62 FR 29684
FRL55971, the Agency presented its general determination that final SNURs are not expected to have a significant economic impact on a substantial number of small entities, which was provided to the Chief Counsel for Advocacy of the Small Business Administration.
D. Unfunded Mandates Reform Act UMRA
Based on EPAs experience with proposing and finalizing SNURs, State, local, and Tribal governments have not been impacted by these rulemakings, and EPA does not have any reasons to believe that any State, local, or Tribal government will be impacted by this action. As such, EPA has determined that this action does not impose any enforceable duty, contain any unfunded mandate, or otherwise have any effect on small governments subject to the requirements of UMRA sections 202, 203, 204, or 205 2 U.S.C. 1501 et seq..
E. Executive Order 13132: Federalism This action will not have federalism implications because it is not expected to have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 64 FR 43255, August 10, 1999.

F. Executive Order 13175: Consultation and Coordination With Indian Tribe Governments This action will not have Tribal implications because it is not expected to have substantial direct effects on Indian Tribes, significantly or uniquely affect the communities of Indian Tribal governments, and does not involve or impose any requirements that affect Indian Tribes. Accordingly, the requirements of Executive Order 13175
65 FR 67249, November 9, 2000, do not apply to this action.
G. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks This action is not subject to Executive Order 13045 62 FR 19885, April 23, 1997, because this is not an economically significant regulatory action as defined by Executive Order 12866, and this action does not address environmental health or safety risks disproportionately affecting children.

i Protection in the workplace. For manufacturing, processing, and use of SN176: Requirements as specified in 721.63a4, 5, 6, and c. When determining which persons are reasonably likely to be exposed as required for 721.63a4, 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. For purposes of 721.63a5, respirators must provide a National Institute for Occupational Safety and Health assigned protection factor of at least 10.
For purposes of 721.63a6, the airborne forms of the substance include particulate including solid or liquid droplets.
A As an alternative to the respirator requirements in paragraph a2i of this section, a manufacturer or processor may choose to follow the new chemical exposure limit NCEL provision listed in the TSCA section 5e consent order for this substance. The NCEL is 0.8 mg/
m3 as an 8-hour time weighted average.
Persons who wish to pursue NCELs as an alternative to 721.63 respirator requirements may request to do so under 721.30. Persons whose 721.30
requests to use the NCELs approach are approved by EPA will be required to follow NCELs provisions comparable to those contained in the corresponding TSCA section 5e consent order.
