Subject: air-inventory New NESHAP and MACT pages on website; other EPA
updates
To Air-Inventory Listserve:
(1) New NESHAP and MACT pages
Maine DEP has recently completed and posted five new pages in its "Air Toxics" section related to National Emission Standards for Hazardous Air Pollutants (NESHAP) and Maximum Achievable Control Technology (MACT) regulations. Please visit them and let us know what you think, http://www.maine.gov/dep/air/toxics/neshap.htm <http://www.maine.gov/dep/air/toxics/neshap.htm> .
(2) Air CHIEF CD-ROM, V. 12
EPA's Emissions Factors and Policy Application Group and the Emissions Inventory Group have released version 12 of the Air CHIEF CD-Rom. The Air CHIEF CD provides access to air emissions data for pollutants that my be emitted from a wide variety of sources. Air CHIEF also offers in electronic format a number of current documents and software widely undes and requested by an international audience. Air CHIEF is available free of charge by filling out an on-line orderform at http://www.epa.gov/ttn/chief/software/airchief/index.htm <http://www.epa.gov/ttn/chief/software/airchief/index.htm> .
(3) 1970 - 2002 Emission Trends
EPA has also released a new version of the 1970-2002 emissions trends data. The readme file explaining changes and the data is now available on the CHIEF website at http://www.epa.gov/ttn/chief/trends/index.html <http://www.epa.gov/ttn/chief/trends/index.html> .
Enjoy the remainder of the summer!

Subject: air-inventory 2004 Inventory Nears Completion; EPA Update on PM from
Natural Ga s
Greetings, Air-Inventory!
(1) 2004 Inventory Nears Completion
More than 95% of facilities have reported to date for
both criteria pollutants and greenhouse gases. Because Becky and I are
both "seasoned veterans" of
the inventory, we're pleased to report that we are more than
3/4 through the QA process and are setting a goal of October 1 for completion
of both inventories. Facilities can help by providing a quick turnaround on
Quality Assurance sheets that are sent out.
Why the hurry? EPA is asking for states to submit the 2005 point source data (next year's inventory) by October 1, 2006 - eight months ahead of the mandated deadline! This is part of EPA's quest to complete the National Emissions Inventory in two years, rather than three years. We're testing our capacity and abilities to meet that early submission deadline. Your use of i-STEPS to electronically submit data and timely turnaround of quality assurance reports is most helpful!
(2) PM from Natural Gas
EPA will be revising PM emissions for a number of Source Classification Codes (SCCs) related to the combustion of natural gas in the 2002 emission inventory. (see e-mail at the end of this message) This is an FYI to all facilities that may use those SCCs as EPA is making these changes without consultation with states and affected facilities.
If you would like to incorporate new emission factors and lower PM emission limits into your air emissions license based on this information, please speak with your Licensing Unit Engineer.
(3) Emissions Inventory Staff Undertaking Residential Wood Combustion Survey
Residential wood combustion is a significant source of criteria and toxic
air pollutants in the area (non-point) sector of Maine's inventory.
However, data has been sketchy in that area since the State Energy Office
stopped doing survey work. In preparation for the 2005 National Emissions
Inventory, DEP Staffer Doug Saball has designed and is implementing a telephone
survey to gather critical activity data on wood burned in residential wood
stoves, fireplaces, inserts, and backyard BBQs. Results should be released
at the end of the year.
As always, please contact the DEP staff with any emissions inventory questions.

Subject: [nei-usergroup] Revised PM emissions in the 2002 NEI for natural
gas combustion
The EPA will revise the PM emissions from natural gas combustion in the final version of the 2002 NEI. The revision will decrease the emissions of PM10-PRI, PM2.5-PRI, and PM-CON by about 95%. The reason for this adjustment is that EPA believes that the current AP-42 factors for condensable emissions are too high. The EPA is basing this adjustment on some limited data from the draft EPA dilution method that is similar to conditional test method (CTM) 39 (http://www.epa.gov/ttn/emc/ctm.html) that measures PM10-PRI and PM2.5-PRI directly.
The data that this adjustment is based on can be found at http://www.nyserda.org/programs/Environment/emepreports.asp#FineParticulates
