3.0 FACILITY DESCRIPTION
3.1 General Information
Puerto Rico Electric and Power Authority (PREPA) - San Juan Power Plant is located on the north coast of Puerto Rico at State Road No. 28, Puerto Nuevo, San Juan, Puerto Rico. PREPA - San Juan Power Plant generates electricity and is categorized under Standard Industrial Classification (SIC) 4911 for Electric Services and the North American Industry Classification System (NAICS) 221112 for Fossil Fuel Electric Power Generation
PREPA - San Juan Power Plant consists of six generating units, four (4) 100-megawatts (MW) oil-fired generating units for a total of 400 MW, and two (2) 200-MW combined cycle units for a total of 400 MW. The electricity generating capacity of the plant is 800 MW.
Electricity generated at the PREPA - San Juan Power Plant starts by feeding de-ionized water into the boiler. De-ionized water is converted into steam. The superheated and high-pressure steam flows through the turbine spinning the blades to generate electricity. Electricity travels to the power grid and is redistributed to where it is needed.

3.2 Process Information
Insp. Dates: September 12-13, 2022
Demineralized process wastewater, stormwater, sludge pond supernatant and equipment wash water and boiler blowdown are directed to the On-Site Wastewater Treatment Plant (WWTP) into one of the three equalization (EQ) tanks with one out-of-service. EQ tank #2 receives demineralized wastewater, stormwater, and sludge pond supernatant. EQ tank #3 receives water from equipment maintenance and cleaning, and boiler blowdown. Process wastewater in EQ tank #3 is pH adjusted between 4-5 Standard Units (SU) and a polymer is added before it is pumped into an off-site sludge pond. The supernatant from the sludge pond is pumped to EQ tank #2 where it is mixed with the other process waste streams. The wastewater in EQ tank #2 is homogenized and pH adjusted to approximately 8.0 SU. As the wastewater from EQ tank #2 is pumped to the flocculation/coagulation chamber of the Nautilus Treatment System, a polymer is injected in-line. Mixing is provided to homogenize the wastewater before flowing into the rectangular clarifier chamber for phase separation. The effluent from the rectangular clarifier chamber overflows the weirs into the effluent trough. The discharge from the effluent trough continues to the polishing chamber. Additional retention time is provided before the effluent is pumped into the media filtration system. The filtrate from the filtration system is stored in the final effluent tank. Adjustment to the pH is performed in the final effluent tank before discharging through Internal Outfall 605.
The effluent from the On-Site Wastewater Treatment Plant combines with other waste streams to discharge into San Juan Bay via Outfall 002.
Backwash from the media filtration system is performed every day. The backwash is pumped to EQ tank #2. The sludge slurry from the rectangular clarifier chamber is pumped into the off-site sludge pond. The sludge from the sludge pond is removed approximately twice per year and is disposed of at an industrial landfill.
3.3 Facility Self-Monitoring Information
Compliance samples are collected by facility's personnel from the designated monitoring locations for all permitted outfalls. Samples collected are analyzed by EQ Laboratories, Inc., in Bayamon, Puerto Rico for Total Suspended Solids (TSS), Color, Turbidity, Cyanide (CN), Polychlorinated Biphenyls (PCBs), Oil and Grease (O&G), Sulfate, Sulfide, and Metals.
4.0 EPA SAMPLING/INSPECTION ACTIVITIES
4.1 Sampling Activities
Samples were collected from the monitoring locations for Outfalls 001, 002 and 003, and Internal Outfalls 603, 604 and 605. For Outfall 001, grab samples were collected and analyzed for color, zinc, turbidity, enterococci, O&G, and sulfate (SO4). For Outfall 002, grab samples were collected and analyzed for color, metals (Cu, Pb, Hg, Ni, Se & Zn), enterococci, O&G, and cyanide. For Outfall 003, grab samples were collected and analyzed
Page 3 of 10
PREPA - San Juan Power Plant, San Juan, PR 00934 NPDES Permit: PR0000698
Insp. Dates: September 12-13, 2022
for color, metals (Cu, Pb, Ni & Zn), turbidity, enterococci, and O&G. From Internal Outfalls 603, 604 & 605, grab samples were collected and analyzed for TSS, O&G, and PCBs. On-site grab samples were collected and analyzed from the outfalls for pH, Temperature, Settleable Solids (SS), Total Residual Chlorine, and Dissolved Oxygen (DO). In addition, temperature was collected and analyzed from Intake 7/8 and Intake 9/10.
All sample containers, preservation techniques and holding times were in accordance with US EPA requirements specified in 40 CFR Part 136. All samples were packaged and shipped through United Parcel Service (UPS) to the USEPA Laboratory in Edison, New Jersey for analysis. Due to the short holding time, enterococci samples were analyzed by Puerto Rico Department of Natural and Environmental Resources (PRDNER) Laboratory in Rio Piedras, Puerto Rico. Chain of custody was maintained for all samples. USEPA and PRDNER Laboratory Analytical Data Packages are attached with the report.
Flow meters were calibrated on February 27, 2020, by INSECO Inc.
Split samples were collected and given to the facility representative.
4.2 Inspection Activities
A NPDES Compliance Sampling Inspection (CSI) at the PREPA - San Juan Power Plant was conducted on September 12-13, 2022. Inspector's credential was presented, and business card was provided during the opening conference. It was explained that the purpose of the CSI with supporting on-site activities was to determine if the facility is in compliance with their NPDES Permit, PR0000698.
The supporting on-site activities consist of observing and confirming the outfalls on the permit (Outfalls 001, 002 and 003, as well as, Internal Outfalls 601, 602, 603, 604 & 605), sampling outfalls that discharged during the inspection (Outfalls 001, 002, and 003, as well as Internal Outfalls 603, 604, and 605), and a tour of the On-Site WWTP.
A brief closing conference was conducted in the field. Split samples were provided to the facility representatives. The inspection activities were briefed to the participants throughout the inspection and during the brief closing conference. On-site sample results and concerns discovered and/or observed during the inspection were communicated to the facility representatives.
4.3 Deviations and/or Environmental Conditions
During the tour of the On-Site WWTP, one of the two Nautilus Treatment Systems was outof-service. The one in-service did not appear to be operating. No flow movement was observed. The mixer in the flocculation/coagulation chamber was not working. The weir plates around the rectangular clarifier chamber were rusted and corroded. No flow was observed flowing over the corroded weir plates. The rectangular clarifier chamber effluent trough was filled with sand and crushed shells as well as the polishing chamber. In addition to the sand and crushed shells, the polishing chamber had very little volume.
