Greetings!
We have a couple of errors to bring to your attention. We apologize for these errors and ask for your continued patience as we put inventory consolidation to real world tests.
(1) Inconsistent SCC Unit and Emission
Factors - We have discovered a problem with SCC 10200903 - External Combustion
Boilers - Industrial; Wood/Bark Waste; Wood-fired Boiler (> 50,000 lb
Steam). When choosing this SCC, i-STEPS defaults users to express throughput
in TONS WOOD BURNED.
Unfortunately, all the emission factors contained in the new SCC table are
expressed in LB/MMBTU. Wrong emission factors = wrong emissions. This error
affects all pollutants - CAP, HAP and GHG.
If you are using this SCC, you may (1) override the standard SCC units and express throughput in MMBTU or (2) change all the emission factors to LB/TON WOOD BURNED by multiplying the emission factor provided by the MMBTU/TON value of the wood. Each calculated emission factor then needs to be entered as a Local Factor (9).
Please contact either Becky Hodsdon or Tammy Gould if you are using SCC
10200903 and we will be happy to discuss these options in detail.
(2) CAS Number error in Consolidated Pollutant List - Two CAS Number errors
were made in the Consolidated Pollutant List we had posted on our website.
The file, 2005PollCodes.xls (2/3/06), has been replaced by a file of the same
name, dated 3/16/06.
The errors are: Benzo(a)pyrene - Correct Poll Code/CAS Num: 50328
Benzo(e)pyrene - Correct Poll Code/CAS Num: 192972
Please correct your copy of the 2005PollCodes.xls or download the new file.
(3) Detail Report Printing Error - We have been advising facilities to use the last page of the Detail Report as their facility's emission synopsis and as part of their certification statement. It was brought to our attention this week that the last page of the Detail Report is not printing all pollutants and emission totals. Specifically, for facilities with more than 50 HAPS, the last page of the Detail Report prints only the first 50 HAPS and no others. We have contacted MACTEC and are seeking immediate help from our contractor to fix this problem. We will relay further information through the Listserve about this problem and work-arounds or solutions as they become available. If significant enough, we will conduct an additional mailing to facilities.
Again, thank you for your patience as we work through these issues. If you have any questions, please feel free to e-mail me or call me.
- Tammy Gould, DEP

Subject: air-inventory Reporting Emissions from Landfills and Wastewater treatment plant s
(1) Publicly Owned Treatment Works (POTW) and Landfills
(2) Industrial Waste Treatment Plants
(3) Source classification codes
(1)Publicly Owned Treatment Works (POTW) and Landfills
For municipal landfills and publicly operated treatment works (POTWs), publication of new and improved emission factors and a change in reporting thresholds in Chapter 137 may result in some of these facilities being required to report this year (for hydrogen sulfide and ammonia respectively). For POTWs, we are working with the Maine Waste Water Control Association (MWWCA)to help their membership in reporting for this inventory cycle.
(2) Industrial Waste Water Treatment plants and landfills For industrial landfills and waste water treatment works, even though these emissions tend to be fugitive, these emissions still need to be reported. To do this, you need to create a separate I-Steps group and process unit for these parts of your facility.
(3) Source Classification Codes (SCC)
SCC's associated with Waste Water treatment plants and landfills are as
follows:

(the weblink to all the SCC codes is http://www.epa.gov/ttn/chief/codes/scc_feb2004.xls)
Please feel free to contact me if you have any questions regarding landfill
or waste treatment plant reporting thresholds or emission factors.
Contact Becky Hodsdon or Tammy Gould if you have any question on how to report
these processes in I-steps.
