State strategies for regulating air emissions during periods of startup, shutdown, and malfunction (SSM) have been a controversial topic in recent years. Air emissions can be higher during periods of SSM because emitting units are not in steady-state operation and some pollution control devices cannot be operated effectively or safely during such events. Since most air emission limitations are not crafted to cover periods when emission units are not operating normally, many states have adopted regulations in their Clean Air Act-required State Implementation Plans (SIPs) to provide compliance flexibility for sources during periods of SSM. These regulations typically take the form of either automatic or discretionary exemptions for emissions that exceed otherwise applicable limitations, or affirmative defenses to liability or penalties for violations asserted by enforcement authorities or private citizens.

EPA Adopts Measures to Improve the Transparency of Significant Agency Guidance
By Andrea Rimer & Louise Dyble on

As anticipated, the Environmental Protection Agency (EPA) announced on June 18, 2020, that it will not regulate perchlorate, a substance primarily found in rocket fuel and munitions, under the Safe Drinking Water Act (SDWA). Before determining to regulate a chemical or substance under the SDWA, the EPA must consider whether (1) the contaminant may have an adverse effect on the health of persons; (2) the contaminant is known to occur or there is a substantial likelihood that the contaminant will occur in public water systems with a frequency and at levels of public health concern; and (3) in the sole judgment of the Administrator, regulation of such contaminant presents a meaningful opportunity for health risk reduction for persons served by public water systems. 42 U.S.C. § 300g-1(b)(1)(A). In its announcement, the EPA concludes that perchlorate does not meet these criteria for regulation.…
