- 6. OP-FTIR: the ultimate petrochemical monitoring system (OTM-10 and fenceline ready) for VOCs, inorganics, and GHG Hundreds of compounds (organic and inorganic) High temporal resolution (concentration roses) Multiple path provides spatial information and allow measurement of flux (OTM-10) Traditionally considered to have moderate detection limits Can, with some investment, be automated to be a bullet proof fenceline and OTM-10 ready system

- 16. Vertical Radial Plume Mapping EPA Other Technical Method 10 (“OTM-10) provides guidance on methodology. Only mass emission measurement test method for fugitive and area source emissions . Has been used with OP- FTIR, UV-DOAS and TDLAS instruments. Has been used to measure emissions from low-to-the-ground sources such as: Landfills Confined animal feeding operations (3 weeks) Superfund & Brownfield sites Chlor-alkali plant (8 weeks) Phosphate processing plant Refueling stations Petroleum refinery process units and tank farms Chemical plants Barges Oil & gas production facilities Iron & Steel coke ovens (7 weeks) Can be installed to collect data over long periods of time.

Six Weeks to Six Months Six weeks, 24/7 of 17 compounds, at Iron and Steel Next, six months, 24/7, 2 OP-FTIR, 4-corner configuration, at a specific area of a refinery (confidential) Longer terms, simplified fenceline monitoring is recommended correlated with at the site with any of the flux measuring methods
- 26. Summary Very good science is being done All methodologies are important tools Long term simplified fenceline monitoring is critical Need to be correlated to short term flux measurement This correlation is site specific Moving toward the stated primary objective – better representation of relevant air toxics and GHG annual emissions calculations for various fugitive and area sources
