A False Sense of Security - Shifts in EPA’s Implementation of PSD Capable of Accommodating Determination and The Demand Growth Exclusion

Everard Ashworth - Ashworth Leininger Group

Description

The 2002 NSR Reforms provided additional flexibility to exclude emissions from existing operations; however, EPA provided little guidance as to how this emissions calculus is to be performed. Come hear the insight gained by the presenter during recent experience in performing a complex and detailed PSD applicability evaluation in the context of utilizing the Demand Growth Exclusion.

EPA NSR Reforms: How to Capitalize Now and Later

Kristin Gordon - ALL4 Inc.

Description

This presentation will provide an overview of the most challenging issues posed by the New Source Review (NSR) construction permitting program for expansion projects. The key aspects of NSR will be summarized along with how they fit in with real world projects (and what makes them most challenging for real world projects). The discussion will then lead to the common sense regulatory and policy reforms that are needed to address these challenges. Finally, we will discuss the current status and anticipated implementation of upcoming reforms to the NSR program by Congress and U.S. EPA. This presentation could serve as an overview for those following the regulatory reform process and also as a primer to those that are attending the in depth NSR workshops.

Recent TCEQ Permitting and Modeling Changes – Lessons Learned and Future Strategies

Frank Dougherty - ALL4 Inc.

Description

The Texas Commission on Environmental Quality (TCEQ) has enacted impactful changes to the way it requires permitting and modeling projects to be completed and submitted. These changes, most of which are required by June 2019, include the introduction of several new air permitting and modeling spreadsheets designed to streamline the air permitting process. During this presentation, we will summarize, review lessons learned, and provide examples on how to use these new workbooks, which are intended to significantly reduce the amount of TCEQ spends reviewing applications.

Ethylene RTR, What’s the Outlook?

Britney Head - ExxonMobil

Description

Per the court-mandated timeline, the EPA is currently working through the statutorily-required risk and technology review (RTR) for the ethylene NESHAP (40 CFR Part 63, Subpart XX and Subpart YY). Industry trade groups have been engaged in meetings with EPA as this process has moved forward. It is anticipated the proposed rule, late this fall, will impact current ethylene operations. It is anticipated the rule will mirror certain aspects of the refinery rule, such as the flare and PRD language and likely will address furnace stack emissions and decoke emissions (both decoke to the fire box and decoke to an atmospheric pot) and potentially waste water emissions. This presentation will discuss the possible proposed rules and the potential impact on the ethylene facilities.

Optimizing NG Compressor Station Permitting

Joel LeBlanc - Ashworth Leininger Group

Description

This presentation puts forth a blueprint for a natural gas compressor station which maximizes compression capacity while maintaining an air emissions minor source status. The presentation will review common emissions sources, go into detail about equipment design considerations for minimizing emissions, and highlight best management practices.

Upstream Oil & Gas Air Permitting 101

Adrienne Rosecrans - Ashworth Leininger Group

Description

This presentation gives a high level overview of air permitting requirements for air emissions sources from the wellhead all the way through Midstream gas treatment facilities. The web of federal and state applicable air permitting and regulatory requirements can be complex to navigate. We will discuss permit applicable equipment types, current federal and state permitting programs and practices, some key best practices, and recent oil and gas industry developments.

RTR Update

Britney Head - ExxonMobil

Description

EPA is proposing multiple Risk and Technology (RTR) rules in 2019 that will affect the chemical and petrochemical industries, including the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Miscellaneous Organic Chemical Manufacturing (MON), Organic Liquids Distribution (OLD), Ethylene Production, and Stationary Combustion Turbines. This presentation will review changes EPA is proposing to make to various NESHAP as a result of their risk reviews, technology reviews, or in response to past court decisions. These changes affect startup and shutdown, stringency of the standards, maintenance procedures, monitoring, and reporting. We will highlight proposed changes that are similar to the Refinery Sector Rule, changes that increase stringency of standards for ethylene oxide emission sources, and where various chemical and petrochemical sector rules will now have slightly different requirements. The presentation will also discuss industry comments submitted to EPA on the major proposed changes.

Photochemical Modeling for Ozone Inter-Precursor Trading

Qi Zhang - GHD Services

Description

In a typical ozone Nonattainment New Source Review (NNSR) project, one requirement is to offset the project emissions of the ozone precursor (nitrogen oxides [NOx] or volatile organic compounds [VOCs]) with emissions reduction credits (ERCs) obtained from a source within the nonattainment area. As allowed by many state agencies, sometimes permit applicants choose to offset one ozone precursor with another precursor for various reasons, primary due to the ERCs for one precursor being unavailable or too expensive. To support this inter-precursor trading, state agencies and the United States Environmental Protection Agency (US EPA) require a photochemical grid modeling analysis to demonstrate the inter-precursor trading will not adversely affect the area’s attainment demonstration.

Once in, Not Always In

Nicholas Petrich - Barr Engineering

Description

The EPA issued new guidance that repealed the “once in, always in” policy, allowing reclassification of a major source of hazardous air pollutants (HAPs) to an area source. Therefore, a major source that obtains federally enforceable limits on its HAP potential-to-emit below the major source thresholds can become an area source. This presentation will provide guidance on how and why a facility can become an area source, including the benefits and challenges. A regulatory overview will be provided, including the common major source standards that would no longer apply, the potentially applicable area source requirements, and why some requirements won’t go away even after reclassification. Also, a technical review will include the critical factors for refining site-specific HAP emissions.

Air Quality Tools for the 21st Century

Robert Opiela - NaviKnow

Description

The air quality permitting process is a data-driven process. Federal permit applicability (do you trigger PSD?), netting calculations, rule applicability, emission calculations, etc. require input data. A permit application cannot be prepared or reviewed without access to the necessary information required by the rules and regulations. Finding, retrieving, and manipulating the dozens of available data sets adds days, even weeks to the processes to prepare and review the permit application. Do you really want to expedite the air quality permit process? NaviKnow Solutions has developed 21st century tools where you can easily locate, access, and download the information needed to complete or review air quality permit applications ALL in one location. We have also developed tools to significantly automate the application review. See how a significant amount of time can be shaved off the air quality permit application process without having to pay for an "expedited" permit application review.

New Building Downwash Options in AERMOD

Sergio Guerra - GHD Services

Description

The presentation will cover the new building downwash options included in the August 2019 version of AERMOD. The current Plume Rise Model Enhancements (PRIME) formulation in AERMOD has a number of theoretical flaws that have been documented on the treatment of downwash in AERMOD. A renewed interest and scrutiny of these downwash shortcomings fueled a parallel, yet complementary, effort led by industry and EPA. These efforts led to the new experimental Alpha options available in the new version of AERMOD. These Alpha options were developed by the PRIME2 committee and EPA’s Office of Research and Development The current presentation will cover the new Alpha options developed along with the implications of this new process to add new science to the regulatory model.
