Subject: air-inventory NOx Emission Factors in i-STEPS

I received notice from one client that the Air Bureau QA review determined
that our reported “emission factors/or emission estimates were NOT reasonable
based on throughput” for NOx from a power boiler.  The emission factor
and method that had been used was i-STEPS method 8 which uses the nationally
recognized AP-42 emission factor and allows i-STEPS to make the calculation
of emissions.  The Air Bureau proposes an emission factor that is almost
double the nationally accepted emission factor.  Certainly, the reported
value was not “unreasonable”.  I applaud the Bureau's efforts to make
the inventory accurate for Maine sources and conditions.  However, while
it may seem beneficial to Maine to use very conservative estimates, there
is a real pitfall.  If we start with high numbers then require a RACT
control technology which then greatly overstates the resulting emission reduction,
the ambient air quality benefit will not reflect the apparent change in emissions
and it may be that the RACT technology did not achieve the expected results,
and certainly not at the expected cost-effectiveness.

If the Bureau has data to support setting a significantly higher emission rate than the AP-42 standard(75 lbs/1000 gallons versus an AP-42 value of 47 lbs/1000 gallons) then that
guidance should be made available to all subscribers to this service as well
as in the general instructions to all who are going to be filing a Chapter
137 report before, not after, the report has been filed. 

The AP-42 emission factors provide factors for 19 different SCC codes for oil fired boilers greater than 100 MMBtu/hour.  The NOx emission factors
are all provided a “rating” from A to E, with A being having the greatest
reliability.  For example, a number 6 oil boiler with normal firing has
a NOx emission factor of 47 lbs/1000 gallons with an A rating while a number
6 oil boiler, tangentially fired with low NOx burners has an emission factor
of 26 lbs/1000 gallons but with an E rating.  The narrative to AP-42
provides a description of the number and consistency of test data and other
methods used to by the factor rating system to classify the reliability of
the factor for each source category.  In this case the factor that the
Bureau finds to be unreasonable was an “A-rated” factor.  To
replace an A-rated factor with another should not be taken lightly and applied
randomly on some boilers but not others.  The Bureau should publish for
peer review the data upon which their proposed replacement emission factor
is based and clearly delineate which SCC categories of boilers that factor
should be applied to and which SCC categories should continue to use the standard
AP-42 emission factors.  The peer review should include EPA OAQPS so
that they could have the opportunity to update AP-42 as well.  When the
Bureau compiles its statistics of how many reports had errors in the 2004
filings, the use of the standard AP-42 and i-STEPS methodology should not
be counted as a submittal with an error.

Subject: air-inventory EPA Announces Landmark Clean Air Interstate Rule

(Washington DC- March 10, 2005) Acting Administrator Steve Johnson today signed the final Clean Air Interstate Rule (CAIR), a rule that will ensure that Americans continue to breathe cleaner air by dramatically reducing air pollution that moves across state boundaries in 28 eastern states. By 2015, CAIR will provide health and environmental benefits valued at over 25 times the cost of compliance and those benefits will continue to grow.
"CAIR will result in the largest pollution reductions and health benefits of any air rule in more than a decade," said Acting EPA Administrator Steve Johnson. "The action we are taking will require all 28 states to be good neighbors, helping states downwind by controlling airborne emissions at their source."

CAIR will permanently cap emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) in the eastern United States. When fully implemented, CAIR will reduce SO2 emissions in 28 eastern states and the District of Columbia by over 70 percent and NOx emissions by over 60 percent from 2003 levels.
This will result in more than $100 billion in health and visibility benefits per year by 2015 and will substantially reduce premature mortality in the eastern United States, and these benefits will continue to grow each year with further implementation.

CAIR is an important component of the Bush Administration's plan to help states in the eastern U.S. meet the national health-based air quality standards. These pollution reductions, along with other federal air quality programs, will allow the vast majority of nonattainment areas in the eastern U.S. to meet the new air quality standards.

Next week, EPA is also scheduled to issue the first-ever requirement for coal-fired power plants to control mercury emissions. That action, plus today's CAIR rule, puts multi-pollutant controls in place for many of the largest sources of air pollution in the country.

"We remain committed to working with Congress to help advance the President's Clear Skies legislation in order to achieve greater certainty and nationwide emission reductions," said Steve Johnson. "But we need regulations in place now to help over 450 counties in the eastern U.S.
protect people's health by meeting stringent new air quality standards."

CAIR will mandate the largest reduction in air pollution since the reductions set by the Acid Rain Program under the Clean Air Act Amendments of 1990. Under CAIR, states will achieve the required emissions reductions using one of two options for compliance: 1) require power plants to participate in an EPA-administered interstate cap and trade system that caps emissions in two stages, or 2) meet an individual state air emission limits through measures of the state's choosing. By addressing air pollutants in a cost effective fashion, EPA and the states will protect public health and the environment without interfering with the steady flow of affordable energy for American consumers and businesses.

(1) i-STEPS Screen Changes and HAPS Reporting
(2) Training Manual Posted
----------------------------------------

(1) i-STEPS Screen Changes - The Department is contemplating a number of changes to the Satellite i-STEPS screens. This would include changes to the Help dialog boxes, changing which fields are required to save a data screen, and changes to the color-coding of the field names. We are seeking input from users on potential changes. Is there something in particular that you could change on a screen that would make it easier to use Satellite i-STEPS?
Please send your comments along by June 3 to Becky Hodsdon, DEP-Air Bureau,
17 SHS, Augusta, ME 04333-0017 or e-mail them to mailto:becky.s.hodsdon@maine.gov.

Any Satellite i-STEPS screen changes will NOT be implemented this reporting cycle. The Department's plan is to package Satellite i-STEPS screen changes with the 2004 data sets (which should be available for release in February 2005). MACTEC, the owner of the Satellite i-STEPS software, will not be incorporating changes in the program download. Maine users will need to download their 2004 data set (or future year data set) for the changes to be incorporated.

The Department is also considering using Satellite i-STEPS to calculate hazardous air pollutants (HAPS) from combustion sources. This would be implemented for the 2005 reporting year (deadline: July 1, 2006). More information will be forthcoming as we work on this added feature.

(2) Training Manual Posted

The Satellite i-STEPS Beginner Training manual, used in classes held recently in Augusta, is available our website. The manual walks users through the entire process -- from downloading the program and data, to editing and adding groups and process units, to exporting the data to DEP.
Several errors discovered during class were corrected. The 42-page manual is available for download at http://www.maine.gov/dep/air/emissions/isteps.htm.

The sample facility file used throughout the manual (Yancy's Yo-Yos) will remain on the ftp site through the remainder of this year.

In January, the list received a message from David Dixon which raised several issues, including questions about emission factor selection (see below). A follow-up letter was received from Mr. Dixon and the Department has responded to his questions with a new guidance document and several new Q&A's on our website.

"Selection of Appropriate Emission Factors and Fuel Use" (May 2005) has been posted on our website at http://www.maine.gov/dep/air/emissions/docs/EF Selection_4_.pdf. The purpose of the guidance is to explain the heirarchy of sources of emission factors used for developing emission inventories and how the Department has arrived at its preferences.

On the Emissions Inventory Program - Criteria Pollutants - Reporting Requirements Questions and Answers page, http://www.maine.gov/dep/air/emissions/crit-rptng.htm, two new Q&A's have been added. They are:

In addition, two new Q&A's have been added to the Emissions Inventory Program - Greenhouse Gases - Reporting Requirements Questions and Answers page, http://www.maine.gov/dep/air/emissions/ghg-rptng.htm.

Subject: air-inventory New Emission Factor Table for Satellite i-STEPS

To Air-Inventory Listserve Recipients:

Several months ago, the Air Toxics and Emissions Inventory Program began discussions with MACTEC, the firm that created the i-STEPS software, about making a number of changes to the Satellite i-STEPS program. These changes would be implemented during the next year and in place for our 2005 inventory (due July 1, 2006). The first of several changes is updating the underlying AP-42 (default) emission factor table with FIRE 6.25 factors.  Maine DEP will be using the Air-Inventory Listserve as the primary means for alerting facilities about these software changes and we are contacting you today about the first step in the process.

MACTEC has provided Maine DEP a comparison of emission factors from the existing AP-42 emission factor table to those in FIRE 6.25. Maine DEP found 198 SCC-pollutant combinations where the existing emission factor in Satellite i-STEPS does not equal the emission factor in FIRE 6.25 or for which FIRE 6.25 has no emission factor. In addition, we found a number of "anomalies" in the existing emission factor table - from historic factors that are no longer supported by U.S. EPA to facility-specific emission factors that erroneously made their way into the emission factor table. Maine DEP must now determine how to address these differences and direct the contractor accordingly.

We have posted a spreadsheet and a memo with further explanation on our ftp site at ftp://ftp.state.me.us/pub/dep/Air-Inventory/. The spreadsheet is named MDEP_newfactor_comment.xls and the memo is named i-STEPS_EFTable_Review_memo.doc. The spreadsheet lists all 198 SCC-pollutant combinations, existing and new emission factors, and contains our preliminary decisions regarding the new factor. In general, we recommend one of four actions:

* Accept new factor - Accepts the new factor from FIRE 6.25. New factors will affect the 2005 inventory.

* Remove old factor, add no new; convert existing entries to method 9 - The existing emission factor will be removed from the i-STEPS emission factor table for that SCC-pollutant combination with no replacement. Where that SCC-pollutant combination is used, the emission factor will become a local emission factor and emission calculations will use Estimated Emissions Method 9 - i-STEPS calculated/Local EF.

* Remove old factor, add no new - The existing emission factor will be removed from the i-STEPS emission factor table for that SCC-pollutant combination with no replacement. Maine DEP chose this option when it was clear that a data entry error may have occurred which placed an inaccurate emission factor in the emission factor table or we believe that a facility chose the wrong SCC for the process.

* Use an alternate emission factor - The MACTEC proposed emission factor does not use standard SCC units and Maine DEP proposes an alternative emission factor to use. All alternatives come from FIRE 6.25, however, they may be revoked factors.

We are soliciting input from the regulated community through the listserve to review of determinations and make suggestions for a smooth transition.

Please send any comments you may have to me via e-mail at tammy.gould@maine.gov, by no later than Friday, July 22. If you have any questions, you may also contact me at (207)287-7036.

Thank you.

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

Greetings, AIR-INVENTORY!

(1) Emissions Inventory Data Posted on Website

The Maine DEP has taken the long-awaited step of posting emissions inventory information on the web. Added to our Emissions Inventory section (http://www.maine.gov/dep/air/emissions/dep-air-info.htm), we have now posted the following data sets:

- 2003 Point Source Greenhouse Gas Emissions Inventory - by facility and pollutant, emission amounts expressed in metric tonnes of CO2 equivalents;

- 2003 Point Source Criteria Pollutant Emissions Inventory - by facility and pollutant, emission amounts expressed in U.S. tons

- 2002 Point Source Criteria Pollutant Emissions Inventory - by facility and pollutant, emission amounts expressed in U.S. tons

"What happens to the data?" is a question asked frequently of our Emissions Inventory staff. In addition to filing the data with U.S. EPA, we have chosen to post it so that others may have ready access to it. Specific data searches, data from years prior to 2002, and facility-specific, process level requests are still available by contacting one of our staff.

(2) 2002 National Emissions Inventory Documentation

Maine DEP has also completed and posted "Methodology Used to Prepare the State of Maine 2002 Emissions Inventory." This 300-page document contains detailed information on how the point, area, mobile and biogenic inventories were developed for Maine's 2002 National Emissions Inventory submission.

The document is particularly detailed in the Area Source sector, where methodologies are included for nearly 200 area source categories included in this sector. Emission factors for both criteria and hazardous air pollutants are also included.

This document can also be found on our DEP Reports page at http://www.maine.gov/dep/air/emissions/dep-air-info.htm.

(3) New and Updated Climate and Waste Tools Available

EPA has developed several additional tools to help you calculate GHG
emissions:

(a) the WAste Reduction Model (WARM). WARM is a user-friendly tool that enables waste managers to estimate the GHG impacts of their actions (source reduction, recycling, composting, combustion, and landfilling).
It is available in Microsoft Excel and in an online version and can be accessed at:
http://yosemite.epa.gov/OAR/globalwarming.nsf/content/ActionsWasteTools.html

(b)the Recycled Content (ReCon) Tool. The ReCon Tool allows users to estimate the GHG emission and energy benefits of increasing the amount of recycled content in materials they purchase or manufacture. It is available in Microsoft Excel and in an online version and can be accessed at:
http://yosemite.epa.gov/OAR/globalwarming.nsf/content/ActionsWasteTools.html

(c) a Durable Goods Calculator that allows users to calculate the GHG benefits of increasing the percentage of durable goods that are recycled.
This tool is available in a Microsoft Excel version only and is also available at:
http://yosemite.epa.gov/OAR/globalwarming.nsf/content/ActionsWasteTools.html

(4) Delaware Air Toxics Study

The State of Delaware has published a particularly thorough report on air toxics in the state. Additional information can be found on their website at http://www.dnrec.state.de.us/air/aqm_page/DATAS.htm.
