Past chairman of the A&WMA EO-3 Committee, Air Quality and Atmospheric Studies, to promote the application of
appropriate dispersion meteorology principles, methods, and models to the collection, analysis, and interpretation of open-path ORS data.
Designed and managed more than 25 ORS field investigations since 1988. Lead author for preparation of USEPAs draft document, Field Standard Operating Procedure for Use of Open-Path FTIR
Spectroscopy at Hazardous Waste Sites. Conceptualized and directed development of SPECTRAMET-1, a commercially available air dispersion model software package to predict downwind pollutant
concentrations in the field based on ORS measurements and on-site meteorological data. Conceptualized development of PICMET-1 and PICMET-2, Minnich and
Scottos proprietary data-management and reporting software for the continual, real-time assessment of Community exposure during the cleanup of former
manufactured gas plant (MGP) sites.
Project manager for the Gas Technology Institutes (GTIs) 2-year ORS methods-development initiative for
perimeter air monitoring during the cleanup of former MGP sites. This project involves field testing of an open-path FTIR spectrometer, open-path UV spectrometer, and Minnich and Scottos proprietary
data-management and reporting
software (PICMET-2), as well as the development of a standard operating procedure (SOP) in concert with the Project Evaluation Committee. The
Committee includes representatives from the five funding utility companies, the law firm of Baker and McKenzie, the USEPA, the Illinois EPA, the New York State
Department of Environmental Conservation, and the New York State Department of Health.
Project manager for ongoing CEQR (City Environmental Quality Review) air quality analyses associated with the
upgrade of two municipal wastewater treatment plants (WTPs) in New York City. For each facility, this work involves estimating pollutant emission rates from all process and building
sources for subsequent use in dispersion modeling to assess compliance with air quality standards at offsite receptors. Hydrogen sulfide is the most problematic pollutant, as significant exceedances were shown, thus requiring emission controls to
be included in the upgrade. We continue to work with engineers from Hazen and Sawyer, the Citys engineering consultant and our client, to identify the
precise combination of controls for each source sub-area minimally necessary to achieve compliance. In this manner, huge cost savings will continue to be realized by avoiding the over-engineering of
Project manager for all phases of the highly publicized radiological soil and indoor air investigation in
residential Montclair/Glen Ridge/West Orange, New Jersey. More than 22,000 hours were spent by 30 field and support personnel involving: radon grab sampling in over 500 homes; gamma radiation exposure-rate assessment via downhole gamma logging and soil characterization; and installation, development, and quarterly monitoring of 16 groundwater
wells. Soil volume estimates for removal were made based on a correlation model developed to estimate the relationship between radium-226 activities and corresponding depth-averaged gamma readings.
Project manager for a $300,000 air quality engineering assessment for a municipal solid waste incinerator in Rutland,
Vermont. The project involved detailed engineering studies in support of the Clean Air Act and Vermonts Hazardous Most Stringent Emission Rate (HMSER)
regulation, and included a comprehensive assessment of ambient air quality involving dispersion modeling in complex terrain. Work included negotiations
with the Vermont Agency of Natural Resources and participation at numerous Agency meetings.
Designed and managed a 2-year intensive air quality investigation for 17 VOCs in a residential area downwind of the
Lipari Landfill site, formerly No. 1 on USEPAs National Priorities List (NPL) for cleanup. This is considered to be the most extensive air quality
investigation conducted anywhere in the US under Superfund. USEPAs TAGA-6000E (Trace Atmospheric Gas
Analyzer) was used to conduct continuous road segment, backyard, and neighborhood monitoring. Results were used in an air dispersion model to estimate residential air toxics exposure.
Project manager for design of a remedial investigation / feasibility study (RI/FS) for a New Jersey site
characterized by widespread dioxin and high levels of pesticides in the soil, and which included buried World War II munitions.
Principal investigator for a 2-year
regional acid rain study in and around the New York metropolitan area, and co-investigator in the 1978 USEPA Northeast Summer Oxidant
Study to develop a layered urban ozone model. Co-investigator in a sulfate/visibility study to characterize long-range pollutant transport,
and a co-investigator in a joint project with Rensselaer Polytechnic Institute
to assess the diurnal nature and transport of ozone and reactive hydrocarbons
at various heights in New York City. Coordinated
24-hour field response team for odor complaints in New York/New
Jersey/Connecticut. Participated in 1976 Great Lakes Summer Research Project to test
the photostationary state theory for ozone. Designed and directed development of a
computer-based graphics system for hazardous chemical emergency spill response
and contingency planning.
Managed or reviewed and approved more than 200
preliminary assessments (PAs) and site inspections (SIs), and numerous special
studies or enforcement-support studies, for the USEPA Region 2 Superfund

Managed comprehensive H2S emissions-measurement programs to support CEQR air
quality analyses for the upgrade of two municipal water pollution control
plants in New York City. For
each facility, this involved coordination and oversight of subcontractors for
meteorological system installation and open-path FTIR spectrometer operations
in support of program execution. Jerome
meters were used for the collection of approximately 3,000 individual samples
at each facility to support emission-rate estimation. Also performed dispersion
modeling to assess compliance with air quality standards at offsite receptors.
To date, these projects represent the only two facility upgrade CEQR air
quality analyses which the NYCDEP, Bureau of Environmental Planning and
Assessment (BEPA) has fully accepted.

revised upwards, and still ensure attainment of all National Ambient Air Quality
Standards (NAAQS) and PSD increments. All sources (33 stacks) in the Peoria area were modeled at each of 398
prediction locations based on 5 years of meteorological data. Results of this study allowed CILCO burn the
higher sulfur-content coal, and led to a cost savings of more than $1 million
Managed all air investigation activities in support of site-wide remedial activities at an industrial facility in New Jersey.
