Re: Updated Enclosure 2 Data - May 20, 2020

Yes, of course we will deal with nonrecovery differently, especially for regulatory purposes, i.e., any changes to the current MACT. The by-product chemical recovery plants will be noncategory emissions and included in the risk assessment for by-product plants but the locations will indicate that these are not co-located at nonrecovery plants. 

You bring up a good point, however, about separating risk for subcategories. Although we are compiling all of the industry data together in same modelling file for ease of data entry and QA, we will likely want to separate the subcategories into separate modelling files before modeling. But we will report separate and combined risk in the preamble and risk documents, but we will only use the individual subcategory risk and emission data for any regulatory decisions. Even if combined, we would indicate zero risk reduction for nonrecovery plants if, for example, we lowered one of the emission limits for by-product, and vice versa.

I don't know anything off hand that we might need to do as far as "gap filling."  I will check with RTI on this to be sure. Did you have anything specifically in mind? For noncategory sources other than chemical recovery, we use the NEI, but the database has specific locations, which will indicate at which plants the noncategory sources are co-located, so that wont be a problem either.

Hi Donna Lee,
 
You should now have all the reviewed Enclosure I and II data from SunCoke.   Thanks for your patience with us.  
 
I also wanted to reach out to you on a related MACT Subpart CCCCC RTR issue.  As you know, SunCoke plants have a different technology and different source profile than byproduct plants; there are numerous emissions units and processes at a byproduct plant that are not present at a nonrecovery plant, resulting in a very different emissions profile.  For example, some of those processes at byproduct plants are regulated under Part 61 Subpart L for benzene emissions.  Additionally, the MACT floor for Subpart CCCCC was set independently for nonrecovery and byproduct plants when those regulations were first promulgated, and as a result, different regulations apply to them.  
 
We are therefore wondering whether EPA is planning to conduct the risk assessment for nonrecovery plants separately from its risk assessment for byproduct plants?  SunCoke's view is that separate risk assessments should be conducted (i.e. determining cancer risk and hazard index independently) because they are distinct subcategories of sources.  We also have a concern that a joint risk assessment using the same gap-filling methodology to estimate emissions for both subcategories of sources would potentially overestimate emissions and risk for nonrecovery plants.
 
Please let us know your thoughts and if it would be helpful to discuss further.
 
Thanks,
