Good morning, David!

We used five years worth of TRI data to determine c omposite VOM and HAP concentration values for use i n the evaporative equation.. I did not compare five years worth of data. I am working on the 2013 annu al emissions inventory. Since thru put data for 2013 was handy, I used it to compare TANKS and evaporati ve methods in the small table I sent on March 3, 2014.

I hope this clears things up!

Have a great day!

Hi Nancy,2 As stated in your email below, the emissions compar ison shown in the table below is for one calendar y ear. Which year is this? Do you have emissions data for more than one calendar year that show what the differenc e in emissions between the two methods is? The email say s you looked at 5 years of TRI data.

Thanks,

David

Hello David,

Section 2.2(E)(3) of TWI's 2008 Title V permit stat es that the TANKS program must be used to calculate emissions from MP1, MP2 and LPR.

Last year, a consultant reviewed our emissions inve ntory process. The **Surface Evaporation Model from EPA Guidance EIIP Volume II:Chapter 8 Section 4.1.4.**  **Preferred and Alternative Methods for Estimating Ai r Emissions from Paint**  **and Ink Manufacturing Facilities, March 1998. Equa tion 8.4-18 was used to calculate emissions from**  MP1, MP2 and LPR. The consultant compiled an average of 5 years of the most recent TRI concen tration data to determine the concentration of VOC and HAP in the waste, which wa s then used in the EPA Surface Evaporation Model referenced above.

TANKS is based on routine displacement of liquids. The surface evaporation model is based on the vola tility and ability of a compound to evaporate from the su rface of solids and then be picked up by the air in the building and carried to the atmosphere. The evapor ation method seems to be more appropriate for MP1, MP2 and LPR; TWI would like to change section 2.2(E)(3 ) of the upcoming permit (or the equivalent section thereof) to indicate the Surface Evaporation Model will be used to calculate emissions from these sour ces.

This table compares emissions calculated by both me thods for the same calendar year:3 TANKS Model Evaporative

model area TPY lb TPY lb MP-1 0.06 117 0.21 424 MP-2 0.02 44 0.11 212 LABPACK/REPACK 0.03 68 0.04 85

I hope this makes sense. Please let me know if you have questions.

Thank you,

Nancy
