Air Quality and Contamination Control Accomplishments

Indoor Air Quality (1994 – Present)

  • Initiated District-wide ventilation protection plan; hardening of new unified command center.

  • Developed Hart Senate Office Building decontamination community protection safety plan.

  • Led bio-decontamination of MM Washington H.S. following Bloomingdale flood.

  • Designed and managed neighborhood indoor VOC sampling program following UST petroleum release.

  • Completed first-ever diesel exhaust field study of effects of bus garage on microenvironment.

  • Developed proactive indoor air quality program within DC Health Department that earned broad support within DC government.

  • Solved major contamination problem for largest elementary school in City of Alexandria.

  • Developed model local government IAQ program recognized by U.S. EPA and local governmental associations for innovation and practicality. Developed IAQ Mediation Service for Mont. Co, MD that resolves commercial and multifamily residential indoor air quality problems.

  • Established indoor air sampling capability (VOC, CO2, CO, microbial, radon, airflow, RH, acoustic) for assessment of local commercial and residential IAQ problems.

  • Performed evaluations and investigations of numerous commercial and residential IAQ complaints in Montgomery County.

  • Consultant to Montgomery County Public Schools on indoor air quality problems in schools. Provided technical analysis of HVAC, VOC, microbial and related issues at specific schools.

  • Served on county expert group that addressed status, causation, and resolution of poor indoor air quality conditions in local public school system.  Principal author of commissioned 1997 evaluation of MCPS IAQ problem.

  • Wrote and published outreach brochures on carbon monoxide, toxic vapors in homes, ground-level ozone, radon, and related environmental health topics.

  • Developed a local radon program aimed at residential outreach, assuring a "level playing field" for testers and mitigators, and raising the level of radon risk awareness by developing and publicizing a locally pertinent radon attributable mortality assessment.

Ambient Air Quality (1971 - 1982 and 1994 - Present)

  • Developed evaluation and control program relative to diesel particulate emissions from District’s major bus fleet and garages.  Innovated use of “aethalometers” for this purpose.

  • Provided analytical support for Metropolitan Washington Council of Governments relative to assessment and visualization of air quality trends and real time data.

  • Restructured and currently administer air quality program for Montgomery County, MD. Work includes ambient and indoor air quality, serving on regional air quality councils, and providing technical assistance to executive and legislative branches of local government.

  • Created and implemented a local government response to episodic ground level ozone events consisting of a government-wide curtailment of precursor emissions, communication to sensitive publics and media of episode's presence and mitigation choices.

  • Major engineering participant in multi-year U.S. EPA - State National Steel Strategy to reduce emissions from coke plants and steel mills throughout the U.S.  Work included analysis of ambient impacts, discovery and application of emissions control technologies, and substantial support for compliance activities in many jurisdictions.

  • Led or co-led EPA groups that were awarded Gold Medal for Exceptional Service (US Steel Monongahela Valley Consent Decree, 1979) and EPA Bronze medal for Significant Achievement (Burns Harbor and Great Lakes Carbon studies, 1976).

  • Led US EPA team in writing and sustaining Reasonably Available Control Technology (RACT) standard for all major steel industry processes to support rule- making following revision of CAA. (Work sustained after challenge in 6th Circuit Court of Appeals.)

  • Wrote US EPA Lowest Achievable Emission Rate (LAER) standard and Technical Support Document for desulfurization of coke oven gas.

  • Led EPA HQ-Region group that developed a comprehensive point and fugitive source emissions inventory for all the major emitting processes throughout the U.S. steelmaking industry.  Program interactively tied to specific emissions control measures underway. Inventory used for policy and technical purposes.

  • Led innovative testing and analysis program which was first to determine air emission factors for by-product coke quench towers.  Tests tied emission rates to water quality levels, which permitted EPA management to support water quality compliance program once untreated water quenching practice was prohibited.

Aerospace Materials and Environmental Engineering and Industrial Hygiene/Contamination Control (1982-1993)

  • Led design effort for NASA to protect Space Station against catastrophic impact from orbital debris - included development of probabilistic risk model, improved outer debris shielding, and fundamental change in structural design of human modules.

  •  Performed first line Industrial Hygiene work in a manufacturing environment: Supervised the restructuring of industrial processes to eliminate toxic emissions and discharges; implemented MSDS training for personnel; measured industrial hood capabilities of major manufacturing areas in company.

  • Created first contamination control laboratory at high technology manufacturing company and invented non-destructive method for measuring in situ non-volatile organic residues.

  • Developed clean process for preventing contamination of printed wiring boards leading to substantial increases in plant-wide production efficiency.  Developed techniques to reduce need for solvent cleaning of electronic assemblies.

  • Established a state-of-art ionizing radiation transport modeling capability.  Recognized by major customers for innovative solutions to radiation shielding and coating problems and awarded company's Outstanding Achievement Award.

  • Designed and carried out a radiation testing and development program to obtain suitable thermal coatings for high radiation environments. 

  • Developed new electroless/electrolytic process for providing high temperature protection to thin structures using an organometallic/ceramic coating.
