Fine Particulate Modeling: Past, Present & Future
Fine Particulate Modeling: Past, Present & Future
Tuesday, October 28, 1:00 pm – 3:00 pm ET
Fine particulates (PM2.5) are perhaps the most important conventional pollutant from a health perspective. Permit applicants must demonstrate new emissions will not exceed the NAAQS by modeling the impact of additional emissions from new or upgraded facilities.
Existing background levels of PM2.5 are very close to the NAAQS in many parts of the country. Considering this lack of headroom and the fact that EPA’s workhorse model cannot adequately handle the chemistry associated with PM2.5, permitting new sources can be a significant challenge. This program will discuss the evolution of PM2.5 modeling, the limits of existing tools, current issues in modeling, anticipated changes, and will provide guidance for permittees and permit writers who must address these issues.

Brian Leahy, Senior Meteorologist, Barr Engineering
Brian Leahy, Senior Meteorologist with Barr Engineering in Grand Rapids, Michigan, has 35 years of experience providing air quality impact analysis, permitting, and regulatory compliance support to sources in the power generation, fuels, mining and general manufacturing sectors. He has conducted hundreds of air dispersion modeling studies across a broad range of regulatory areas, including PSD and minor source permitting, state air toxic policies, risk assessments, enforcement and litigation, odor response and mitigation, and chemical accidental releases. He routinely uses atmospheric dispersion models commonly employed in industrial permitting, state implementation plan, and federal implementation plan development. Brian is an active participant in air quality issues pertaining to modeling and is frequently invited to speak on air quality and dispersion modeling matters.
Moderator: Harry Klodowski, Principal, Klodowski Law LLC
Harry Klodowski has practiced environmental law in Pittsburgh since 1979. While a student at SUNY Buffalo 1972-1979,(BA,BA,MA,JD) he watched the local Love Canal story develop into CERCLA, and entered the job market in time for the Regan purge of EPA in 1981. His practice covered air, water and waste for basic industry, as well as small business. He has obtained NSR and air toxics permits for metals plants and has completed over 30 ERC transactions in support of NSR air permits. At A&WMA he is a Fellow Member, is in his seventh year on the International Board and has been recognized for achievement by the Board, the Education Council, and Sections & Chapters Council. Harry will be A&WMA president in 2026.
