RE: FLORIDA SHADY HILLS GENERATI NG STATION PSD APPLICATION :

RESPONSE TO EMAIL REQUEST FOR ADDITION AL INFORMATION AND

SUPPLEMENT TO PENDIN G APPLICATION

Dear M s

. Oquendo :

This correspondence provides the project clarifications requested by the United States Environmental

Protection Agency (EPA) , via email correspondence received on June 25, 2013, and June 28 th , 2013,

concerning the Shady Hills Generating Station PSD Permit application , and constitutes a supplement to

the pending application

. Golder is submitting t his information on behalf of the applicant, EFS Shady Hills

LLC

.

1. From June 25 th , 2013 Email from Ana Oq uendo, EPA

a. The maximum potential annual VOC emissions as presented in Table 2

- 7 of the

permit application submitted to FDEP dated July 9, 2010, mentioned “VOC (as

methane)”. Since methane is a GHG , please confirm whether there will be methane

emissions actually been released from the storage tank and provide an estimate of

methane PTE emissions for this unit.

b. Provide GHGs PTE estimates for the circuit breaker as well as for the fugitive

emissions from the proposed on

- site pipeline and natural gas supply.

Response :

a. As part of the FDEP permit application VOC emissions from the on

- site fuel oil storage tank

were estimated utiliz ing EPA’s Tanks Program. Fuel oil is composed of heavy petroleum

fractio ns C9

- C20 and as such CH4 (methane) is not expected to occur as fugitive emissions

from the fuel oil storage tank. The US Chemical Substances Inventory under the Toxic

Substance Control Act defined Diesel Oil as “A complex combination of hydrocarbons

prod uced by the distillation of crude oil. ” It consists of hydrocarbons having carbon numbers

predominantly in the range of C9

- C20 and boil s in the range of approximately 163

- 357 deg.

C.

b. Attached Tables 5 and 6 include emission estimates for the proposed new c ircuit breakers

and for the on

- site piping components associated with the new CTs and supporting newMs

. Ana M. Oquendo

. July 26 , 2013

ancillary equipment. The information provided on the new piping components and circuit

breakers is based on initial estimates only.

2. From June 28 th , 2013 Em ail from Ana Oquendo, EPA “I appreciate the quick response

to the question about the emergency generator rating. I kindly request that Table 1

(highlighted fields) are also updated according to new numbers in Table 4. If the other

two inquiries implicate a change in the total GHGs PTE emissions, Table 1 should be

revised to account for those changes in emissions.”

Response : Table 1 has been updated to include GHG PTE emissions from the proposed new

emergency generator, new gas heater, new circuit breakers, and natural gas piping associated with

the project.

In addition to the responses provided above, Roy Belden provided additional information to EPA via email

submitted on June 26, 2013 indicating the intent to permit the emergency generator rated at 2,500

kW. Updated FDEP application forms pages affected by this correction are included in this submittal.

EFS Shady Hills LLC appreciates EPA’s consideration of this additional information . If you have any

questions , please contact Mr. Roy Belden at (203) 357

- 6820 or Scott Osbourn at (813) 287

- 1717 in

Tampa.
