1.0 OBJECTIVE
On September 10-11, 2024, 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 the Weco Manufacturing facility in Ontario, New York. The objective of the CSI was to gather information necessary to determine compliance with the requirements and limitations of 40 CFR Part 433 (Metal Finishing Point Source Category) and the industrial wastewater discharge permit issued by the Town of Ontario Wastewater Treatment Plant (WWTP).

3.0 FACILITY DESCRIPTION
3.1 General Information
Weco Manufacturing is located at 6364 Dean Parkway in Ontario, New York. The facility is a contract manufacturer of metal products for the healthcare, aerospace, defense, energy, and electronics industries. Products include machined components, finished fabricated sheet metal, and assembled metal products. The company is categorized as Standard Industrial Classification (SIC) Code 3499 (Fabricated Metal Products, Not Elsewhere Classified). The plant operates 16 hours per day, 5 days per week, with two 8-hour shifts. The 50,000 square foot facility currently has 56 employees. The plant began its operations at this location in 2001.

3.2 Process Information
Inspection Date: September 10-11, 2024
The raw materials come into the facility as metal sheets, rolls, rods, or bars. The raw materials are composed of stainless steel or aluminum. Custom fabrication of metal parts can include computer numeric controlled (CNC) machining, programmed laser cutting, shearing, punching, drilling, forming, welding, riveting, and deburring. The parts are then conveyed to the metal finishing shop, where there are two metal finishing lines. The iron phosphate line is used to finish stainless steel parts. The parts are dipped in a soap solution, rinse water tank, acid etch tank, two rinse water tanks, iron phosphate tank, and a neuralization tank. The chromate conversion line is used to finish aluminum parts. The parts are dipped in a soap solution tank, rinse water tank, acid etch tank, two rinse water tanks, clear and yellow chromate solution tank, clear chromate solution tank, and rinse water tank. The final rinse water tank is routed through a cation/anion system for chrome removal and is reused as rinse water.
Process water for the facility is provided by the Town of Ontario. Incoming water is treated with a water softener and then processed through an on-site reverse osmosis (RO) system. The RO water is stored in a tank and is used to fill the rinse water tanks. The spent rinse water from Rinse Tank #3 and Rinse Tank #7 flows through two iron filters before it is collected in a 2400-gallon wastewater holding tank. The process wastewater is batchdischarged daily to the Town of Ontario WWTP through a drainpipe located at the 600gallon level of the tank. The remaining 600 gallons of wastewater is pumped to the evaporator. After evaporation, the remaining sludge is placed in containers and shipped as non-hazardous evaporator sludge to Safety Kleen.
3.3 Facility Self-Monitoring Information
Pretreatment wastewater samples are collected and analyzed daily for pH, flow, iron, and chromium. Pretreatment wastewater samples are collected every six months for local permit parameters and the parameters listed in 40 CFR Section 433.17. Samples are analyzed by Paradigm Environmental Services in Rochester, New York.
4.0 EPA SAMPLING/INSPECTION ACTIVITIES
4.1 Sampling Activities
On September 11, 2024, a batch discharge was scheduled for the 2400-gallon wastewater holding tank. The discharge started at 1008 with the level in the tank at 1600 gallons. The discharge ended at 1105 with the level in the tank at 600 gallons. The total discharge to the Town of Ontario WWTP was 1000 gallons. A composite sample of the discharge was collected by filling the sample containers manually with a 25 percent aliquot every 15 minutes. The samples were collected from a sample tap on the discharge line. The
Page 4 of 7

Inspection Date: September 10-11, 2024
composite sample was analyzed for 5-day biochemical oxygen demand (BOD5), total suspended solids (TSS), ammonia, metals (arsenic, cadmium, chromium, copper, iron, lead, mercury, nickel, silver, and zinc), cyanide, total phenolics, and TTO non-volatile organics. Four grab samples for TTO volatile organics were also collected during the batch discharge. The four grab samples were composited in the laboratory. Grab samples for pH and total residual chlorine were collected and analyzed in the field.
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.

Project Narrative:
UNITED STATES ENVIRONMENTAL PROTECTION AGENCY Region 2 Laboratory
Final Report Project: Weco Metals Pretreatment CSI - 2409009
Project Number: 2409009
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
SVOA Analysis: NPDES requirements were not met in S409029-ICV1. Multiple calibrations were run in an effort to meet NPDES criteria. All data in ICV not meeting the acceptance limits were biased high and the corresponding sample 2409009-01 did not have any hits. Therefore, Qualifier "K" is not applicable and no qualifications were needed.
In addition, there were several compounds outside QC limtis in LCS/LCSD with low % recoveries and high %RPD. Based on these results, "J" and "L" qualifiers were applied accordingly to sample 2409009-01.
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.
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.
