II. Discuss Questions (submitted prior to the webinar) on System Calibration Video Clip (Arthur Eberle – 30 mins.)

III. Alternatives to Incandescent Light Bulbs in Transmissometers (Erik Haas – 5 mins.)

IV. ASTM D7520-09 Standard Test Method to Determine the Opacity of a Plume in the Outdoor Ambient Atmosphere using a Digital Camera Technique (Jason Dewees – 30 mins.)

A. How ASTM D7520-09 Works

B. Update on Broadly Applicable Alternative Test Method (Alt-082)

6/16/09 EPA has issued an information collection request (ICR) that will require some companies to measure the emissions of hazardous air pollutants from their boilers. Guideline Document 51 (GD 51) provides an overview of approved methods, target pollutant units of measure, and reporting requirements for the ICR. This document will be updated regularly to show approved changes to the recommended methods and approved alternative methods. The guideline document will also have a regularly updated list of FAQs about the testing program, so check it frequently to get the latest information about the boiler ICR.

You can find the document under Instructional Materials, then Guideline Documents, or click here to go there immediately.

04/28/09 EMC, in conjunction with Battelle, held a workshop, "Nanoparticle Air Monitoring," on March 2-3, 2009, to gather information on the different types of particles and monitoring techniques. The goal of the Workshop was to identify drivers and needs for monitoring nanoparticles in source and ambient air, and specific gaps and promising solutions in meeting those needs. Recognized experts shared their experience and understanding of the issues in the first sessions of the workshop. On the second day, group discussions were held to identify actions to fill knowledge and technology gaps. EPA and attending organizations are using the workshop outcomes to consider and plan their nanoparticles air monitoring efforts. The presentations are available at this link.
