Subject: air-inventory BEP adopts Ch. 137 and NEW Emissions Training and
Website
------------------------------------------------------------
1. Board adopts Emissions Statement Rule
2. Emissions Inventory Training
3. New Emissions Inventory Website
-------------------------------------------------------------
1. Board adopts Emissions Statement Rule The Board of Environmental Protection adopted changes to Chapter 137, "Emission Statements" on June 17, 2004. Chapter 137 establishes requirements for sources to report air emissions from their facilities. The amendments require sources to report ammonia, fine particulates and greenhouse gases in addition to pollutants they already report. The rule was amended at the Board meeting to require a one-ton de minimis reporting level for greenhouse gases and a July reporting deadline for all pollutants.
(Editor's note: When the rule is posted to the DEP website, an announcement will be sent through Air-Inventory.)
2. Emissions Inventory Training. With the passage of Chapter 137, the Emissions Inventory Program has kicked into high gear. Letters requesting the 2003 Emissions Inventory will be mailed to all facilities on Monday, June 28. The deadline for inventory submission this year is September 1. In addition to collecting data on criteria pollutants, this will be our first year collecting greenhouse gas emissions. To assist facilities with this new reporting requirement and to explain the changes in Chapter 137, we will be offering two Emissions Inventory Training classes. The first training program is scheduled for Augusta on July 28; the second will be an on-line webcast on August 4. Registration is required for the training sessions. To register, contact Tammy Gould (287-7036 or mailto:tammy.gould@maine.gov)
3. New Emissions Inventory Website. In addition to the upcoming training sessions, the Emissions Inventory Program proudly unveiled a new website this week, http://www.maine.gov/dep/air/emissions/. The expanded site contains information on criteria pollutant, greenhouse gas and hazardous air pollutant reporting, as well as in i-Steps "How To" Guide and information for the general public on how to get information about emissions near their homes. Check it out!

Subject: Version 11 Air CHIEF CD From: "CHIEF Info" <info.chief@epamail.epa.gov> Date: Thu, 24 Jun 2004 09:05:03 -0400 X-Message-Number: 1
The Emission Factor & Inventory Group has released version 11 of the Air CHIEF CD-ROM. Air CHIEF is available free of charge by filling out the online order form at http://www.epa.gov/ttn/chief/software/airchief/index.html We will begin shipping the CD July 15, 2004.
The Air CHIEF CD-ROM gives the public and private sector access to air emission data specific to estimating the types and quantities of pollutants that may be emitted from a wide variety of sources. Updated annually, Air CHIEF offers on one disc literally thousands of pages contained in some of EPA's most widely used and requested documents. Included are the US EPA Emission Factor and Inventory Group's most popular emission estimation tools.

-----Original Message----- From: David [mailto:dwdixon@gwi.net] Sent: Tuesday, June 29, 2004 4:03 PM To: air-inventory@informe.org Subject: air-inventory Greenhouse gas emissions reporting Do I understand that emission factors are not included in I-STEPS for greenhouse gases and that facilities must essentially file two emission statements for 2003; one for criteria air pollutants using I-STEPS and a second one using the spreadsheet or other format to quantify greenhouse gas emissions.
I am concerned with having clients sign the certification statement using emission factors provided by the licensing staff review when those factors are not consistent with the AP-42 emission factor generally built into the I-STEPS calculations. The few that I saw provided no basis for suggesting an alternative factor but if it is based on an emission test or test from a comparable facility it would seem appropriate that the reason for using other than the normal factor should be explained. Have you compiled data to show the difference in total emissions before and after the 2002 QA effort?
In response to the discussion at the Board meeting when Chapter 137 was amended, will the Bureau provide some written guidance about de minimis sources so that calculations are not required to prove that emissions from certain operations are below 1 ton/year? Will this issue be discussed at the training program?
Regarding the list server, is there a web site to log onto to view the responses to other questions that have been asked or is everything just handled via e-mail?

Subject: RE: air-inventory Greenhouse gas emissions reporting
Lot's of questions in one e-mail! Here goes:
First, we are not using i-Steps for greenhouse gas emissions. That is
because we do not need greenhouse gas emissions calculated to the
process-segment level; only to the facility level. Facilities can use a
spreadsheet or another piece of proprietary software (as long as DEP can
check the calculations) to develop the emissions footprint. The greenhouse
gas sheet (green paper included in the recent mailing) is for summarizing
emissions for ease of data entry.
Second, you or your clients should take up their individual concerns with
the appropriate Licensing Unit Engineer. AP-42 factors are based on
national emission data models. While AP-42 is built into i-Steps, it may
not be the most accurate emissions factor for an individual facility. I
don't believe that we compiled statistics on whether emissions went up or
down, but anecdotally, the impression that I got from observing the process
was that more went down than up.
Third, no, we are not prepared at this time provide any more guidance on de
minimus sources. We hope that people will focus first on combustions sources
and, as we all get better at this, work our way down from there. By the
time of training, I hope to have a sheet showing how much burning of
individual fuels would equal one-ton. (We'll also post that on the
website.) I would be very interested in suggestions for de minimus sources
from this list.
Finally, no, we are not preparing a web site to view past responses. Sorry.
Please save past messages as you see fit.
