## New and revised parts 51, 60, and 63 test methods

- Method 207 – VOC from corn wet milling operations
- Pre-survey procedure for compounds and sampling approach (M18, M308, NCASI CI/SG/PULP-94.03)
- Available as OTM-11 on EMC website
- To be proposed in late 2007

- Method 208 – VOC from hot mix asphalt plant dryers
- Protocol for collecting, analyzing, and reporting data
- Procedure based on Method 25A (FIA), available as OTM-12 on EMC website
- To be proposed in late 2007
- Contact: Gary McAlister, MTG

## Alternative methods

- Broadly applicable alternative methods approvals
- FR notice – 01/30/07
- Announces plan to publish alternative method approvals for broad applications rather than judt site-specific approvals
- GD-022 – process for obtaining approval
- Contact: Robin Segall, MTG

## Alternative and other methods

- Digital camera for visible emissions opacity measurement - PRE-008 on EMC website
- Currently in development in ASTM committee, potential alternative to Method 9
- Contact:  Tom Logan, MTG

## Alternative and other methods

- Optical remote sensing (ORS) for fugitive gases - OTM-10 on EMC website
- Path-integrated ORS technology (FTIR, UV-DOAS, TDLAS, PI-DIAL)
- Peer-reviewed and potential alternative method
- Contact:  Robin Segall, MTG

## Alternative and other methods

- Portable methods for periodic monitoring – OTM-13 on EMC website
- For O2, CO, and NOx
- Design and performance criteria
- Contact: Foston Curtis, MTG
- Isocyanate sampling and analysis – OTM-14 on EPA website
- Proposed as Method 207 in 1997
- No plans to promulgate, but method available for use as needed
- Contact: Gary McAlister, MTG

## Improving emissions monitoring through rulemaking

- Performance Specification 16
- Predictive emissions monitoring systems (e.g., NOx from combustion sources)
- Proposed August 2005
- Prepared response to comments document
- Promulgate in late 2007
- Contact: Foston Curtis, MTG

## Improving emissions monitoring through rulemaking

- Performance Specification 17 – verifying operation of continuous parameters monitoring systems
- To be used with MACT rules with process operating limits
- For T, ΔP, pH, Qliq, conductivity
- Drafts developed with stakeholder input
- Proposal planned later in 2007
- Contact: Barrett Parker, MPG

## Improving emissions monitoring through rulemaking

- PMfine Implementation rule
- Method 202 and other fine PM method work that Ron Myers discussed
- Guidance to States on setting representative emissions limits - anticipated after rule issued
- Contact: Tom Driscoll, MPG

## Tools for improved monitoring and testing

- Monitoring knowledge base
- Interactive compilation of information linking monitoring and control device technologies on TTN/CHIEF website
- Expansion from current version and links with RACT/BACT/LAER expected in 2007
- Contact: Barrett Parker, MPG

## Tools for improved monitoring and testing

- Fugitive VOC and dust monitoring
- Collaboration with mining and petroleum industry on monitoring technologies and revised EFs
- 2006 workshop on VOC reviewed IR camera, differential absorption light detection and ranging (DIAL) spectroscopy, and radial-plume mapping spectroscopy (report on TTN/CHIEF)
- 2007 VOC workshop being planned
- Contact: John Bosch, MPG
