then EPA is required to issue standards for categories of sources of hazardous air pollutants as necessary to protect the public health with an ample margin of safety or to prevent an adverse environmental effect. sugar skull oakland raiders football team full over printed shirt A residual risk standard is required for any source emitting a cancer-causing pollutant that poses an added risk to the most exposed person of more than one-in-a-million. Residual risk standards are due eight years after promulgation of MACT for the affected source category. Existing sources have 90 days to comply with a residual risk standard, with a possible two-year extension. In general, residual risk standards do not apply to area sources. The Clean Air Act provides statutory authorities to facilitate compliance with the Good Neighbor provision.
For example, if EPA finds a SIP inadequate to achieve a NAAQS, it must require the affected state to submit a revised SIP that includes sufficient measures to bring that state into compliance. This is known as a “SIP Call.” The 1990 Clean Air Act amendments provided EPA and the states with new tools to address the transport problem. One of those tools is Section 176A, a provision that permits EPA, either on its own or by petition from any state, to establish a transport region to address regional pollution problems contributing to violations of a primary NAAQS. A commission of EPA and state officials is constituted to make recommendations to EPA on appropriate mitigation strategies. Based on the commission’s findings and recommendations, EPA is then required under section 110 to notify affected states of inadequacies in their current state implementation plans and to establish deadlines for submitting necessary revisions. Besides authorizing administratively-created transport regions,
