  1. OPEN-PATH MONITORING BY JOHN BOSCH SEPTEMBER 2007

  2. RECENT ACTIONS • NATIONAL REGULATORY IMPACTS • NEW PERMIT MONITORING • SIP STRATEGY CHANGES • NEW STUDIES ARE MUSHROOMING • NEW TECHNOLOGIES DEVELOPING

  3. HISTORY OF OPEN-PATH • PRIMATIVE PRE-1990’S • OVERPROMISES OF THE 1990’S • NEW DETECTORS, LASERS, AND SOFTWARE • ELIMINATION OF MODELING ERRORS AND NEW ALGORITHMS

  4. THE HARD WORK • MILITARY RESEARCH PROGRAMS • EPA’S SOLID WASTE SUPPORT • OAQPS WORKSHOPS AND CONFERENCES • APPROVED PROTOCOLS • LANDFILLS, GASOLINE STATIONS, AND AGRICULTURE OPERATIONS • REFINERY STUDIES

  5. THE NEW STUFF • FTIR • DOAS • DIAL • DOPPLER • OPTICAL REMOTE SENSING PROTOCOL • IR CAMERAS

  6. THE POLLUTANTS GASES ORGANIC AND INORGANIC SPECIFIC AND TOTAL METHOD 21—FIND IT AND FIX IT PARTICULATES WIND VECTORS FOR MASS FLUX

  7. PRELIMINARY RESULTS OF OPEN-PATH WORK • REFINERIES: AT LEAST ONE ORDER OF MAGITUDE GREATER EMISSIONS THAN PREVIOUSLY REPORTED—MORE THAN 40 TIMES FOR BENZENE • THE NEW TECHNOLOGIES WORK AND PROVIDE MORE ACCURATE AND CONTINUOUS EMISSION MEASUREMENTS • MANY UPSTREAM AND DOWNSTREAM PETRO-SOURCES REMAIN TO BE COUNTED (AIRPORTS, WELLHEADS, NETWORKS)

  8. FUTURE WORK • WORKSHOPS PLANNED • NEW IN-DEPTH STUDIES • MILITARY FOCUS • EXTENDED APPLICATIONS
