1.0 OBJECTIVE
On September 12-13, 2023, at the request of the Water Compliance Branch, the United States Environmental Protection Agency (USEPA) conducted a National Pollutant Discharge Elimination System (NPDES) Pretreatment Compliance Sampling Inspection (CSI) at Trenton Renewable Power LLC in Trenton, New Jersey. The objective of the CSI was to gather information necessary to determine compliance with the general pretreatment requirements of 40 CFR Part 403 and the industrial user permit issued by the New Jersey Department of Environmental Protection (NJDEP).

3.0 FACILITY DESCRIPTION
3.1 General Information
Trenton Renewable Power is located at 1600 Lamberton Road in Trenton, New Jersey. The facility is a food waste recycling and renewable energy company that converts food waste into methane and compost. The plant operates 24 hours per day, 7 days per week. There are 19 employees that work three shifts. The plant was designed to accept 450 tons of food waste per day. Currently, the facility processes approximately 260 tons per day. There are three 1.1 megawatt generators that use the methane produced on site. Approximately 2 megawatts of carbon-negative energy are produced per day. A large source of the food waste is agricultural waste at ports that has been rejected due to improper temperatures. Other sources include food waste and expired package products from grocery stores and warehouses.

3.2 Process Information
Inspection Date: September 12-13, 2023
Food waste is delivered by truck to the facility and is separated from packaging materials using shredders, grinders, and magnets. The food waste is conveyed to a 480,000-gallon buffer tank. Water is added to the tank from one of three sources: the effluent from the Trenton Sewer Utility Wastewater Treatment Plant (WWTP), the influent to the WWTP, or two process water tanks. After mixing, the food waste is pumped to one of three thermophilic anaerobic digesters. The heat exchangers maintain the temperature at 52oC inside the digesters. The retention time in the digesters is approximately 30 days. After digestion, the sludge is conveyed to two centrifuges, where the sludge is dewatered. The solids are collected in a roll off container for disposal at a local landfill. The decant liquid wastewater is conveyed to the ammonia stripper and then an oil-water separator. The wastewater is then discharged through Outfall DSN 001L to the Trenton Sewer Utility WWTP.
Methane gas from the digesters is collected in a storage tank for use as fuel for the generators. Solids are currently sent to a local landfill for disposal. The facility plans to market the solids as compost in the future.
3.3 Facility Self-Monitoring Information
Pretreatment wastewater samples are collected monthly in accordance with the industrial user permit issued by NJDEP. 24-hour composite samples are collected for the analysis of 5-day biochemical oxygen demand (BOD5), total suspended solids (TSS), total phosphorus, total ammonia, and metals. Grab samples are collected for pH, and oil and grease. Flow is monitored continuously.
4.0 EPA SAMPLING/INSPECTION ACTIVITIES
4.1 Sampling Activities
On September 12, 2023, an automatic composite sampler was set up at the effluent chamber for Outfall DSN 001L. The sampler was programmed to collect an aliquot of the effluent wastewater every 15 minutes for 24 hours. After 24 hours, the automatic composite sampler was disassembled, and the composite sample jug was mixed thoroughly before filling the sample containers. The 24-hour composite sample was analyzed for BOD5, TSS, total phosphorus, total ammonia, and metals (arsenic, cadmium, chromium, copper, lead, nickel, zinc, and mercury). During the 24-hour sampling survey, a grab sample was also collected at Outfall DSN 001L for oil and grease. A grab sample for pH was collected and analyzed in the field. The 24-hour flow was recorded from the totalizer and provided by the facility representative.

Inspection Date: September 12-13, 2023
All sample containers, preservation techniques, and holding times were in accordance with U.S. EPA requirements specified in 40 CFR Part 136. All samples were placed in a cooler with wet ice and transported to the U.S. EPA Region 2 Laboratory in Edison, New Jersey.
The facility representative declined the EPA offer for split samples.

6.0 FINDINGS
6.1 Sampling Result Findings
Analytical results indicate that all parameters did not exceed daily maximum discharge limitations in the industrial user permit during the 24-hour sampling survey.
The analytical result for BOD5 exceeded the monthly average limitation in the industrial user permit but the result was qualified due to toxicity of the sample toward the seed organisms. This is explained in more detail in the project narrative of the attached Laboratory Data Report.

Project Narrative:
UNITED STATES ENVIRONMENTAL PROTECTION AGENCY Region 2 Laboratory
Final Report Project: Trenton Renewable Power LLC - 2309019
Project Number: 2309019
The National Environmental Laboratory Accreditation Conference Institute (TNI) is a voluntary environmental laboratory accreditation association of State and Federal agencies. TNI established and promoted a National Environmental Laboratory Accreditation Program (NELAP) that provides a uniform set of standards for the generation of environmental data that are of known and defensible quality. The EPA Region 2 Laboratory is NELAP accredited. The Laboratory tests that are accredited have met all the requirements established under the TNI Standards.
Condition Comments
None
Comment(s):
The "Sample Analysis Date and Time" is included in the results section for any analyte with a prescribed holding time of 72 hours or less.
Biochemical Oxygen Demand (BOD) Analysis: Sample 2309019-02 exhibited toxicity toward the seed organisms used for BOD. This is demonstrated by increasing BOD values as sample dilution increases. Only the result for the largest sample dilution is being reported instead of the average of all acceptable dilutions; the average is used when the sample does not exhibit toxicity. Since an even higher sample dilution may have produced a higher BOD result, the sample was qualified with an "L" to indicate the result is biased low.
Oil and Grease Analysis: Sample 2309019-01 was not successfully analyzed using the SPE method. The sample clogged the SPE disk with only a fraction of the sample passing through. A separatory funnel extraction based on method 1664 was also attempted in which an emulsion formed which did not break. The sample is qualified with an L due to failing MS recovery.
Data Qualifier(s):
U- The analyte was not detected at or above the Reporting Limit. J- The identification of the analyte is acceptable; the reported value is an estimate. K- The identification of the analyte is acceptable; the reported value may be biased high. L- The identification of the analyte is acceptable; the reported value may be biased low. NJ- There is presumptive evidence that the analyte is present; the analyte is reported as a tentative identification. The reported value is an estimate.
