Shirley:

Thanks for the note on timing.

Attached for your use are the District application forms that provide additional specifications on the proposed emitting equipment

Avenal #0 8 -SJ-01: "Heads Up" list

Eric,

I will rely on you to forward, as needed, w/in your team regarding thi s "heads up" per the previous string of e/m this morning

.

a) Project Description - I will check internally what level o f equipment description detail (specifics vs. generic) we need for ou r process. At a minimum, if detail is provided, we will ensure consistenc y with the PDOC, where applicable.

b) Emissions - I still need to develop my working spreadsheet to ensur e I properly understand the potential wors t -case scenarios (e.g. modeling related) and operations - normal, start-up/shutdown, and other transien t periods. I will focus initial on the wors t -case scenarios - emission estimates and description of operating scenarios

.

c) BACT - CO - - - At this point, I will check internally regarding the CO 4 ppm level (proposed) compared to the proposed 2 ppm level of a comparable project to be located in SJVAPCD

. NH3 slip - - - At this point, I will check internally regardin g the proposed NH3 slip level compared to our other recent projects an d general approach for NH3 slip. Technology evaluation - - - At this point, it is likely we wil l want a "top-down" assessment for the control technology evaluation

. Therefore, initial thoughts: P a g e 2 o f 3

5 / 24 / 2011 f il e :// C :\ D o c u m e n t s a nd S e tti ng s \ S R I V E R 02 \ L o c a l S e tti ng s \ T e m p \ no t e s B AAA 25 \

. ..CTs/HRSG - - - May ask, at a minimum, for evaluation of Emerache m

technology. I also am going to see what other NOx technologies t o consider. Others - - still processing on what we typically have internally fo r the other equipment.

d) AQIA - Carol to address. See item (b) above

.

e) Additional Impacts Analysis - Will be checking on Visibilit y Impairment Analysis requirement. Will also check on Soils an d Vegetation. For a different PSD project I have oversight, I have tw o references given to me from a modeler. "A Screening Procedure for the Impacts of Air Pollution Sources o n Plants, Soils, and Animals", EPA 450/ 2 -81-078, December 1980 EPA's "Workbook for Plume Visual Impact Screening and Analysi s (Revised), EPA-454/R-92-023, October, 1992

. So I will be looking at whether/how these are applicable to Avenal' s analysis.

f) ESA - On-going.

gotta run to training. checkin later - s
