Biographical Information George J. Schewe, CCM, QEP, Principal Consulting Meteorologist, Trinity Consultants 1717 Dixie Hwy, Suite 900, Covington, Kentucky 41011 859-341-8100 x109 gschewe@trinityconsultants.com Mr. Schewe is a Certified Consulting Meteorologist as well as a Qualified Environmental Professional who has over 40 years of dispersion modeling and air quality management experience in Kentucky, Indiana, and Ohio. He has prepared permit applications, interfaced with state agencies, prepared overall air quality impact assessments as well as regulatory review requirements, prepared additional impacts analyses, and modeled both criteria and toxic chemical releases to assess potential air impacts. He has contributed to a wide variety of environmental assessment studies including Prevention of Significant Deterioration, non- attainment area net emission modeling, state and federal air toxics analyses and risk assessments, RACT and BACT assessments, and State Implementation Plan (SIP) preparation. He has used modeling approaches for emergency as well as routine releases of air contaminants. He has prepared modeling studies covering plantwide point-source emissions as well as plantwide fugitives from roadways, materials handling, waste and scrap areas or other process related fugitive emissions. While with the U.S. EPA, he performed dispersion modeling in support of emission standards development and helped develop and improve industrial source dispersion models. He has conducted numerous workshops, seminars, and technical classes over the past 25 years for the U.S. EPA - Air Pollution Training Institute, Ohio EPA, and the Dayton Regional Air Pollution Control (RAPCA). Christopher Beekman, PhD, Specialist III, Ohio EPA PO Box 1049, Columbus, OH 43216-1049 614-644-3597 christopher.beekman@epa.ohio.gov Dr. Beekman is a 1999 graduate of Muskingum University with a B.S. in Chemistry and Environmental Science, and a 2009 graduate of The Ohio State University with a Ph.D. in Environmental Science. He started his career well outside of the environmental field in 1999, working as a chemist in a research lab focused on the development of novel cancer treatments incorporating known cancer-fighting pharmaceuticals with nano-engineered silica particles. His doctorate research focused on open path spectroscopy of the atmosphere, atmospheric chemistry, and the combination of air dispersion models with state-of-the-art solar radiative transfer models. Chris joined the Ohio EPA in 2012. His responsibilities include air quality modeling, the Mercury and Air Toxics Standards, and Ohio’s electric generating utility inventory. He works in the State Implementation Plan section of the Division of Air Pollution Control. Chris is Ohio EPA’s main contact for the electric generating utilities in Ohio. He also serves as the primary contact for the NOx Budget Trading Program, Cross State Air Pollution Rule, and the Mercury and Air Toxics Standards. Chris has been with the Ohio EPA for six years.

He manages various environmental and sustainability projects and programs across the enterprise, most recently focused on Midwest Gas Operations in the Cincinnati and Nashville metro areas. Previously, he has been involved with National Emissions Standards for Hazardous Air Pollutants (NESHAP – MACT) implementation, Acid Rain monitoring programs, New Source Review (NSR) project determinations, evaluation of greenhouse gases emissions and reports, and waste management programs, all leading to compliance and cost reduction. Robert shares responsibility for EPA compliance in air, water and solid waste media at Duke gas operations, projects and gas facilities in the Midwest. He has worked in the environmental field for over 25 years, including employment at corporate, manufacturing/industrial facilities, power generation plants and in consulting. Robert holds a master’s degree in environmental science and engineering from the University of Cincinnati and bachelor’s degree in atmospheric science from the University of Missouri. He holds professional certifications as a Professional Engineer (PE) in Ohio and broadcast meteorologist from the American Meteorological Society (AMS). Robert has been an active A&WMA member in the East Central Section since starting his environmental career and is currently Vice Chair in the Southwest Ohio Chapter. He has presented papers, presentations and participated in voluntary efforts in support of the A&WMA. Brian M. Otten, Consultant, Trinity Consultants 1717 Dixie Hwy, Suite 900, Covington, Kentucky 41011 botten@trinityconsultants.com Brian M. Otten, Consultant, is currently employed with Trinity Consultants residing in the Covington, KY office location. He has worked with numerous industrial clients in Kentucky, the Greater Cincinnati Area, and supports other Trinity offices in providing service to industrial clients across the U.S. He is proficient in dispersion modeling and has used many of the options in AERMOD as well as other models like the BLP Model for characterizing coke ovens and rooftop vents for aluminum smelters. Prior experience includes air dispersion modeling, air quality permitting, and emission characterization for electric power generation, the mineral products industry, oil & gas refining, and various other manufacturing facilities. He also assists clients in regulatory reporting (e.g toxic release emission inventory (TRI) and annual compliance certification), facility-wide emission inventories, and regulatory applicability determinations. Brian as a degree in Environmental Engineering from Purdue University.

S o what are MERPs? George S chewe Trinity Consultants Environmental solutions delivered uncommonly well
Introduction - Definition MERP = M odeled E mission R ates for P recursors Environmental solutions delivered uncommonly well
So What is a Precursor? ˃ S ome pollutants are “ primary” meaning they are directly emitted by sources to the atmosphere ˃ S ome pollutants are “ secondary” meaning they are not emitted directly but form in the atmosphere either chemically or mechanically ˃ “ Precursors” are primary pollutants that convert to secondary pollutants Environmental solutions delivered uncommonly well
Sources of Air Pollution PM 2.5 , PM 10 Environmental solutions delivered uncommonly well
Precursors of Interest ˃ S O 2 converts to sulfates – a particulate ˃ NO 2 converts to nitrates – a particulate ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ˃ NO 2 involved in the ozone generation process ˃ VOCs involved in the ozone generation process Environmental solutions delivered uncommonly well
How are Precursors Used? ˃ If the emissions from a new or modified source represent a level of increased precursor emissions that are not expected to contribute to significant levels of ozone or PM 2.5 then no further analysis required ˃ These levels of precursor emissions are called the De Minimis Levels below which no modeling or detailed qualitative assessment is needed Environmental solutions delivered uncommonly well
So Let’s Talk About What MERPs Apply to ˃ Particulates – especially PM 2.5 ˃ Ozone – O 3 ˃ What’s the big deal? ˃ Why look at these pollutants? Environmental solutions delivered uncommonly well
PM 2.5 –A Breakdown ˃ PM 2.5 = Particulate Matter < 2.5 µm “ Primary” PM 2.5 emissions Directly emitted as PM 2.5 Includes filterable and condensable “ S econdary” PM 2.5 emissions ♦ NO X + S O 2 emitted as precursors ♦ React atmospherically to form particulate Source: Particulate Matter Science for Policy Makers – A NARSTO Assessment, 2003. 12 Environmental solutions delivered uncommonly well
