Air Plan Approval; District of Columbia; Removal of Stage II Gasoline Vapor Recovery Program Requirements
The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the District of Columbia. This SIP revision removes requirements for gasoline vapor recovery systems (VRS) installed on gasoline dispensers, the purpose of which are to capture emissions from vehicle refueling operations, otherwise known as vacuum-assist Stage II vapor recovery. Specifically, this action would remove from the approved SIP the prior-approved Stage II requirements applicable to new and existing gasoline dispensing facilities (GDFs). The District of Columbia SIP revision includes a demonstration that removal of Stage II requirements is consistent with the Clean Air Act (CAA) and meets all relevant EPA guidance.
Significant New Use Rules on Certain Chemical Substances (21-4.F)
EPA is proposing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances that were the subject of premanufacture notices (PMNs). The chemical substances received "not likely to present an unreasonable risk" determinations pursuant to TSCA. The SNURs require persons who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use by this rulemaking to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the use, under the conditions of use for that chemical substance. In addition, the manufacture or processing for the significant new use may not commence until EPA has conducted a review of the required notification, made an appropriate determination regarding that notification, and taken such actions as required by that determination.
