RE: Do you have time for a quick call


Hi Donna Lee,

I hope you had a wonderful holiday season and start to 2022.  I wanted to get back to you about the attached email and also ask you a follow up question or two regarding the information you provided below.

First, in response to the attached email, we cannot tell from the data provided whether it was intended to include HRSG costs, and that figure would be low even without HRSGs.  Based on our estimates, the cost of a new heat recovery plant with HRSGs would be on the order of $750 million for that size plant.

Regarding your email below, we greatly appreciate the information you've shared and EPA's willingness to incorporate some of our recommendations.  Can you also please give us an idea where EPA landed on cancer risk for nonrecovery plants?

More importantly, we are wondering what your current thinking is on potential updates to the standards for nonrecovery ovens in light of risk findings.  We know that you asked a number of questions late in 2021 about bypass venting in general and Jewell in particular, and we were hoping to minimize the possibility of new requirements that are not technically feasible being introduced in a proposed rule.  For instance, each plant is rather unique and that is why the bypass venting requirements vary among them.  We are happy to have a conversation with you and provide additional information to clarify anything.

Thanks!

Kris

Hi. The posted modeling file reflects these changes below.

We incorporated your suggestion from your 7/7/21 email to reduce emissions by the ratio of ovens per stack for Vansant bypass vent stacks. 

Your 7/7/21 email brings up the issue about SC-EastChicago-IN having a baghouse. We adjusted the emissions using the control efficiencies SunCoke provided in the review of the modeling file development, by 0.99/0.98. We had already been using 98% control, so we adjusted slightly upwards (decreased emissions) after your email.

We would use facility boundaries in the acute assessment, but there were no acute HQs > 1, so facility boundaries were not used.

Do we still need a call?

Hi Donna Lee,

Would you have time for a quick phone call (<30 minutes) with me a Katie sometime next week? We just had a couple of things we wanted to discuss. We are both pretty open on Monday but could do other days depending on your availability. Please let us know.
Thanks!

Kris
