On October 29, EPA published a proposed revision to its Cross State Air Pollution Rule (CSAPR) Update in response to the remand of the rule by the D.C. Circuit. The CSAPR Update was promulgated under the Clean Air Act’s “Good Neighbor” provision, which requires states to ensure that pollution from sources within their borders does not significantly contribute to the ability of downwind states to attain or maintain the National Ambient Air Quality Standards (NAAQS). Under the Good Neighbor provision, if a State Implementation Plan (SIP) does not adequately address the interstate transport of pollutants, EPA must step in and issue its own rules through a Federal Implementation Plan (FIP). EPA issued the CSAPR Update in 2016, imposing FIPs on 22 states requiring ozone season NOx reductions from electric generating units (EGUs) to address the 2008 ozone NAAQS. In the 2018 CSAPR Closeout, EPA determined that no further emission reductions were required for all but two of the states covered by the CSAPR Update.

As of September 4, 2020, Illinois has responsibility for direct administration of the Prevention of Significant Deterioration (PSD) permitting program under state regulations, including federal Clean Air Act (CAA) requirements under authority delegated by the U.S. Environmental Protection Agency (EPA). In doing so, Illinois joins 46 other states that have elected to administer the PSD program directly.  State PSD regulations, added as Part 204 of the Illinois air quality pollution rules, 35 Ill. Adm. Code Part 204, were published in the Illinois Register on September 19, 2020.

Illinois is taking the final steps toward adopting an authorized state program for direct administration of the Prevention of Significant Deterioration (PSD) permitting program under proposed state regulations, taking responsibility for federal Clean Air Act (CAA) requirements previously administered under delegated authority from the U.S. Environmental Protection Agency (EPA).

On May 5, 2020, the Illinois Attorney General filed a complaint against a developer and its contractors responsible for demolishing the smokestack of a former coal-fired power plant in Chicago. The suit provides a good reminder that careful planning for the control of fugitive dust emissions is critical during decommissioning activities—and that state legal offices

Under the Clean Air Act, a facility that emits air pollutants may not be constructed unless an air permit has been issued to the facility.  For decades, EPA has interpreted the statute to prohibit almost any construction or modification activities until a permitting authority issues a final permit.  But on March 25, 2020, EPA proposed new guidance to clarify that, according regulations adopted 40 years ago, the only construction prohibited prior to issuance of an air permit is construction on the emitting unit itself.

On March 9, 2020, EPA published its final “risk and technology review” for the standards it adopted in 2004 to regulate emissions of hazardous air pollutant (HAP) from natural gas-fired combustion turbines. Like most other such reviews, EPA confirmed that the risks presented by HAP emissions from the source category are acceptable with an ample margin of safety. EPA also concluded that there are no new cost-effective controls for reducing those emissions.

Last week, EPA fulfilled a promise to reverse the expansion of its refrigerant management program during the Obama Administration. That expansion, which was finalized in 2016 and became effective in 2019, EPA extended the regulations for ozone depleting substances (ODS) to non-ODS “substitute” refrigerants, with the intent of reducing emissions of substitutes that consist of greenhouse gases (GHGs), including some with very high global warming potentials. Last week’s final rule returns the refrigerant management program to its original focus, at least with respect to appliance leak repair requirements, although some regulatory requirements for non-ODS substitute refrigerants will remain in place.

EPA’s New Source Review (NSR) reform efforts have been in full swing over the past month or so as the Agency released two final guidance documents, issued a pre-publication version of a proposed rule, took final action to end a years-old reconsideration of a 2007 rulemaking, and released its Fall Unified Agenda detailing dates for a number of upcoming NSR-related actions. While these actions may not have immediate consequences for many regulated sources, they are evidence that EPA continues to pursue its NSR reform agenda.

Under the Obama Administration, the Environmental Protection Agency (EPA) issued a rule on January 13, 2017 amending parts of the Clean Air Act’s (CAA) Risk Management Plan (RMP) program, which regulates facilities that use hazardous substances.  Among other things, the Obama Administration’s 2017 RMP Rule implemented new requirements related to technology and alternatives analyses, third-party audits, disclosure requirements, and incident investigations.  Similarly to other areas of environmental law, the Trump Administration expressed its intention to repeal these requirements shortly after entering office.  After issuing a May 30, 2018 proposed rule and considering nearly 77,360 submitted comments, the EPA recently made good on its intention by releasing the pre-publication version of final RMP Reconsideration Rule that, among other things, repeals the Obama Administration regulations.

The final rule incorporates most of the substantive provisions in the proposed rule.  In addition to repealing much of the 2017 RMP Rule, the RMP Reconsideration Rule modifies the requirements related to local emergency coordination and compliance dates for some provisions.  The Reconsideration Rule will become immediately effective upon its publication in the Federal Register, which should occur soon.  Parties are also expected to challenge the RMP Reconsideration Rule in court, potentially resulting in the delay of the rule’s effective date or its reversal.  One potential challenger is a contingent of fourteen state attorney generals that submitted negative comments on the proposed rule.  More recently, the states submitted another comment listing chemical incidents that have occurred since the proposed rule, which they argue further evidences the need to keep the 2017 RMP Rule.

On June 25, 2019, EPA released a pre-publication draft of a proposed rule allowing sources subject to Maximum Achievable Control Technology (MACT) standards under Section 112 of the Clean Air Act to voluntarily limit their emissions and avoid MACT.  The proposed rule, which formalizes and expands on a January 2018 guidance document issued by former EPA Assistant Administrator Bill Wehrum, would allow “major sources” of hazardous air pollutants (HAPs) otherwise subject to MACT standards to take an enforceable limit on HAPs and thus reclassify as “area sources.”  The rulemaking, branded by the Agency as “Major MACT to Area” (MM2A), would eliminate the Agency’s longstanding “once-in-always-in” policy, under which a facility that qualified as a major source of HAPs as of the “first substantive compliance date” of the applicable MACT standard was permanently subject to that standard, even if the source was later able to reduce its emissions below major source applicability thresholds.
