Box 364267 San Juan, Puerto Rico 00936-4267 Re: Final Permit- Prevention ofSignificant Deterioration (PSD)- for the San Juan Combined Cycle Project- Puerto Rico Electric and PowerAuthority (pREPA) Dear Mr. Plaza: On December 16, 2002, PREPA submitted a PSD permit application for the construction ofa 476 megawatt combustion turbine combined cycle electric generating station at the San Juan site. The U.S. Environmental Protection Agency (EPA) issued a Proposed PSD Permit for public comments on January 23, 2004. The public comment period commenced on February 6,2004. EPA also held two Public Availability Sessions on February 18, 2004, related to this permit. The purpose ofthese sessions was to conduct outreach to the public beyond that which is required by 40 CFR Part 124, in order to explain the project and be available to clarify the permitting actions and procedures. During these sessions only one individual asked for clarifications. EPA also indicated many times during these sessions that any comment on this PSD permit must be submitted in writing by the close ofthe public comment period. This is consistent with the requirements in 40 CFR §124.11 that comments must be submitted in writing. EPA also indicated in its draft permit public notice that any request for a public hearing must be submitted within 15 days ofthe notice. No such request was submitted. EPA did not receive any written comments during the public comment period which ended on March 8, 2004. Therefore, EPA today issues the proposed permit as final without any changes to the proposed permit. This final permit will allow PREPA to construct two new Westinghouse 501 combustion turbines which will use distillate oil with 0.05% sulfur as the only fuel. These turbines will be limited to operate for a total of15,000 hours per year. Additionally, the existing four boilers (7- 10) will be modified to lower the nitrogen oxide (NOx) emissions and use heavy oil with 0.5% sulfur. EPA has determined that this final permit meets all applicable requirements ofthe PSD regulations codified at 40 CFR §52.21 and the Clean Air Act (the Act). Accordingly, EPA hereby approves PREPA's PSD permit for the Combined Cycle Project. This letter and its enclosures represent EPA's final permit decision. A project description and summary ofthe control technologies to be used are provided in Enclosure I. The permit conditions are delineated in Enclosure II. This final permit decision becomes effective today. Since no comments were received during the public comment period, this permit maynot be challenged under the Consolidated Permit Regulations, codified at 40 CFR Part 124, that apply to EPA's

On January 23, 2004, EPA issued aproposed pennit for this project. 

### In this project, PREPA proposed to install and operate two (2) 238 megawatt (MW, net) combined cycle turbines. The facility will produce electricity from Westinghouse 501 distillate oil fired

. combustion turbines, each with a power output of171 MW, an additional 67 MW electricity will be produced by two steam turbines driven by two Heat Recovery Steam Generators (HRSG). No supplemental firing offuel will be used in the HRSGs. Each combustion turbine will burn No.2 fuel oil having a maximum sulfurcontent of0.05 percentby weight. Both turbine units will be operated 15,000 hours per year. As apart ofthis project, PREPA proposes to modifyburners to lowerNitrogen Oxide (NOx) emissions from four existing residual fired boilerunits (7 through 10) and switch to using 0.5% from 1.5% sulfurheavy oil in those units. The total capacity at this site will increase from 400 MW to 876 MW afterrepowering. PREPA also proposed to install two new 2.5 MW auxiliary diesel generators, convert two existing residual fuel oil storage tanks to no. 2 oil storage tanks, install two new fixed roofstorage tanks (one for no. 2 oil and the other for residual oil) and will install six new cooling towers for auxiliary equipment cooling. PSD-Affected Pollutants Emitted at the PREPA Sa·n Juan Repowering**~roject:** The existing facility is classified as a major stationary source because it has the potential to emit more than 100 tons per year ofat least one pollutant regulated by the Clean Air Act. Based on this proposal, EPA has concluded that PSD will not apply to (i.e., PREPA will net out ofthe PSD review for) sulfur dioxides (S02)' particulate matter (PMIPM 10) and sulfuric acid mist (H2S04). The lead emission increase will be below significant level for PSD review. However, PSD will apply to nitrogen oxide (NOx), carbon monoxide (CO) and volatile organic compounds (VOCs). In addition, the new combustion turbines will be limited to 85.6 % annual capacity (or 15,000 hours) utilization. Under these conditions, there will be a net decrease or no significant increase in emissions ofsulfur dioxides (S02)' sulfuric acid mist (H2S04), particulate matter (PMIPM 1o), and lead (Pb). PREPA Combined Cycle Project Control Equipment: The proposed facility will employ Best Available Control Technology to control NOx, CO and VOC. Emissions ofnitrogen oxide will be controlled by installing a steam injection system in the combustion turbines. The steam to fuel ratio for each unit shall be established during perfonnance testing and shall be incorporated into this PSD pennit. NOx emissions from the existing four residual oil fired units 7 through 10 shall be reduced bymodifying burners and good combustion control. Emissions of carbon monoxide and volatile organic compounds will be controlled by implementing good combustion practices. PREPA shall be required to operate each turbine within the designed combustion parameters of the Westinghouse 501 distillate oil fired combustion turbine. 

### In addition, PREPA shall be Page 1 of 7required to monitor t. combustion temperature and fuel flow rate ol_.ch turbine, and to maintain each turbine in good working order. \, This pennit further requires that the proposed facility.employthe following control techniques to net out ofPSD applicability for the otherpollutants: Emissions ofsulfur dioxide and sulfuric acid mist shall be controlled by the use 9fonly low sulfurNo.2 fuel oil in which the sulfur content may not exceed 0.05% by weight in the combustion turbines and by the use of0.5% sulfur heavy oil in the existing boiler units 7-10. Emissions of total particulate matter and particulate matter less than 10 microns will be controlled by implementing good combustion practices. The auxiliary diesel generators will be limited to a total of40 hours per year ofoperation. The storage tanks will be installed with a fixed roofand the cooling tower particulate emissions will be controlled by installing drift eliminators. Summary: Table Iprovides the summary ofnet emissions from this project. As indicated in the table, there are three pollutants, NOx, CO and VOC, for which the facility is subject to PSD. Table II summarizes the PSD netting analyses and Table ill lists BACT and other controls for this project. Table IV and V relate to air quality analyses pertaining to this project.

• Unlike the November 30, 2000, PSD Permit, which showed a 84.8 tons/year net decrease in NOx emissions, this proposed permit netting analyses shows a net emission increase in NOx. This is because EPA is no longer crediting decreases in NOx for the retiring ofUnits 5 and 6. Note that PREPA proposes to operate the turbines 15,000 hours per year vs. 12,067 hours per year in the earlier PSD permit.
