Inspection Dates: July 23-24, 2024
twin screw extruders to provide colorants, additives, compounds, and resins to the plastic industry for injection molding, extrusion, blown film extrusion, blow molding, rotational molding and thermoforming. The final products are distributed to personal care, pharmaceutical, medical, cosmetic specialty packaging, advertising displays houseware, and toy industries.
Marval Industries, Inc. is located at 315 Hoyt Ave., Mamaroneck, New York (NY). The facility employs approximately 42 people, operating twenty-four (24) hours per five (5) days with three (3), 8-hour shifts (7AM-3PM, 3PM-11PM, & 11PM-7AM). Marval Industries, Inc. is categorized under Standard Industrial Classification (SIC) 3082 - Unsupported Plastics Profile Shapes and the North American Industry Classification System (NAICS) 326121 - Unlaminated Plastics Profile Shape Manufacturing.
3.2 Process Information
Marval Industries, Inc. receives municipal water for sanitary usage and manufacturing operation. Municipal water is not treated prior to use in the manufacturing operation. Generated process and sanitary waste streams comingled before discharging into the town sanitary sewer collection system.
The manufacturing process starts by combining the dry raw material [Polyethylene, Polypropylene, Polystyrene, Polyamide (Nylon), Acrylic, Acrylonitrile Butadiene Styrene (ABS), colorants and additives] into the Blender. The raw materials are tumbled and mixed to create a uniform blend. After blending, the entire content is deposited into a Gaylord box and is forklifted onto a higher platform. The dry blend is fed into a receiving hopper. The hopper feeds the barrel and screw extruders. The extrusion process involves the application of heat around 420 degrees Fahrenheit (F) and pressure to force the dry blend into a molten or semi-solid state enabling the barrel/screws to create the resin. Colors are mixed with the resin after the extruder die plates to acquire the specific color and texture requested. The extruded resin emerges from the die plates in a continuous stream of pliable resin into the cooling trough. The plastic resin is cool and harden as it moves through the water. As the plastic resin emerges from the cooling trough, an air blower dries the plastic resin to minimize water loss and further cools the plastic resin. From the cooling trough, the plastic resin is fed into the Pelletizer to be cut into small pellets. The small plastic resin pellets slide onto the Classifier. The small pellets are categorized by size. Finally, the accepted pellets are collected and packaged to be ship to their customers. Any undersized and oversized pellets are collected and returned to the receiving hopper.
Municipal water is used to replenish the cooling troughs in Building No. 1 and Building No. 2. As the hot extruded resin is fed into the cooling troughs, the water is displaced and/or evaporated. The displaced water overflows into a side-screen compartment that captures lost and/or excess plastic resin from the extrusion process. In Building No. 1, the process

Inspection Dates: July 23-24, 2024
waste streams are combined with sanitary wastewater in the drained pipe that connects to Building No. 2 sewer line after the monitoring location. In Building No. 2, all the process waste streams from the cooling troughs are connected to the sump pit, except one. Solids within the wast streams are captured by a cloth filter as the waste streams free-fall into the sump pit for settling. As the water level rises in the sump pit, the pretreated process wastewater is pumped through the discharged pipe. Downstream of the discharged pipe, the pretreated process wastewater combines with the untreated process waste stream from the extrusion operation that is not connected to the sump pit. Further downstream, sanitary wastewater from bathrooms and breakroom mixes with the process wastewater before reaching the monitoring location.
Solids collected from the cooling trough screens and the cloth filter are disposed of as regular trash.
3.3 Facility Self-Monitoring Information
Marval Industries, Inc. hired HydroEnvironmental Solutions, Inc. to collect pretreated process wastewater samples for compliance purpose with Marval Industries, Inc. Wastewater Discharge Permit. All the parameters on the permit are obtained through a portable automatic composite sampler that is programmed to collect an aliquot every hour during the 24-hour sampling event. The parameters collected are BOD5, TSS, Metals (As, Cd, Cr, Cu, Pb, Hg, Ni Ag & Zn), Total Cyanide, Total Phenolics, pH, O&G, SVOCs, and VOCs. The composite sample is distributed between the containers which are provided by York Analytical Laboratories and Phoenix Environmental Laboratories. The compliance samples are analyzed by York Analytical Laboratories located at 120 Research Drive in Stratford, Connecticut.
4.0 EPA SAMPLING/INSPECTION ACTIVITIES
4.1 Sampling Activities
An ISCO automatic composite sampler was programmed to take 96 sample aliquots during the 24-hour sampling event at the monitoring location. The 24-hr composite sample was collected and analyzed for Metals (As, Ba, Cd, Cr, Cu, Pb, Hg, Ni, Se, Ag & Zn) and Hexavalent Chromium.
Grab-composite samples were collected at various time intervals for Non-Volatile Organic Analytes (NVOAs) and Total Cyanide.
Grab samples were collected for Oil & Grease (O&G), Total Phenols and Volatile Organic Analytes (VOAs). Four (4) sets of grab samples for VOAs were collected at various time
Page 4 of 10
Marval Industries, Inc., Mamaroneck, NY 40 CFR Parts 403 & 414 & SIU Permit
Inspection Dates: July 23-24, 2024
intervals during the 24-hour sampling event. The four sets of VOA grab samples were composited in the laboratory.
Furthermore, on-site grab samples were collected and analyzed for pH, Temperature, and Total Residual Chlorine (TRC).
All sample containers, preservation techniques and holding times were in accordance with USEPA requirements specified in 40 CFR Part 136. Signed and dated custody seals were placed across the lids and along the sides of the sample containers. The custody sealed sample containers were placed inside plastic sample bags and sealed. All samples were transported on ice to the USEPA Laboratory in Edison, New Jersey for analysis.
Split samples were collected and given to the facility representative.
4.2 Inspection Activities
A Pretreatment Compliance Sampling Inspection (CSI) at Marval Industries, Inc. was conducted on July 23-24, 2024. The inspectors met with Thomas Zimmerman; President, Logan Osberg; Operations Manager, Nicholas Carbone; HydroEnvironmental Solutions, Inc. Environmental Engineer, and Monika Wieleba; Westchester County Department of Environmental Facilities Industrial Pretreatment Program Coordinator. Inspector's credential was presented, and business card was provided during the opening conference. The facility representatives were explained that the inspection purpose with supporting onsite activities was to determine if Marval Industries, Inc. is in compliance with the Federal limitations, requirements and conditions of 40 CFR Parts 414.111 & 403, the Wastewater Discharge Permit and other related Federal regulations.
Supporting on-site activities consist of collecting samples of the pretreated discharged effluent at the monitoring location, observing and evaluating the monitoring location, observing and evaluating Marval Industries, Inc. sampling protocol, observing and evaluating the process wastewater flow from the manufacturing operation, reviewing and evaluating the on-site sampling procedures, reviewing and evaluating the chain-of-custody, observing and evaluating the laboratory analytical data and sample containers, as well as, sample preservation, and interviewing the facility's representatives.
The facility's representatives were briefed on the inspection activities throughout the inspection and during the closing conference. On-site sample results and concerns discovered during the inspection were communicated to the facility's representatives so that they understand their responsibilities to comply with the conditions and limitations set forth in the Federal regulations and their Wastewater Discharge Permit.

4.3 Deviations and/or Environmental Conditions
Inspection Dates: July 23-24, 2024
Pretreated and untreated process waste streams, and sanitary wastewater from Building No. 2 are mixed before reaching the monitoring location. Furthermore, process waste streams and sanitary wastewater from Building No. 1 comingle with the wastewater from Building No. 2 after the monitoring location. Due to the various waste streams combining at different points within the facility's sewer collection system between the two buildings and accessibility issue, representative sampling could not be obtained. A professional judgement was made to sample at the monitoring location based on interviews with representatives from the facility and the Westchester County Department of Environmental Facilities IPP Coordinator.
In addition, samples for O&G could not be collected from the monitoring location due to accessibility. A professional judgement was made to collect the samples from the sump pit in Building #2.

6.0 FINDINGS
6.1 Sampling Result Findings
The EPA analytical results obtained during this inspection are within the acceptable limits.
6.2 Inspection Findings
In addition to the analytical data, an inspection of the facility operations was conducted as discussed in Section 4.2 above. During the inspection, the following observations were noted which may contravene the requirements of the applicable Federal regulations and the Wastewater Discharge Permit:
6.2.1 The samples collected at the monitoring location is not representative of the pretreated effluent. According to Part II - Definitions in the Wastewater Discharge Permit, it states, "Self-Monitoring - Sampling and analyses performed at the Industry by the Industry itself in accordance with 40 CFR Part 403." In 40 CFR Part 403.12(b)(5)(ii) for Measurement of Pollutants, it states, "In addition, the User shall submit the results of sampling and analysis identifying the nature and concentration (or mass, where required by the Standard or Control Authority) of regulated
Page 8 of 10
Marval Industries, Inc., Mamaroneck, NY 40 CFR Parts 403 & 414 & SIU Permit
Inspection Dates: July 23-24, 2024
pollutants in the Discharge from each regulated process. Both daily maximum and average concentration (or mass, where required) shall be reported. The sample shall be representative of daily operations." Furthermore, 40 CFR Part 403.12(b)(5)(iv) for Measurement of Pollutants, it states, "Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exists."
6.2.2 All the parameters in Marval Industries, Inc. Wastewater Discharge Permit are collected as 24-hour composite sample using an automatic sampler. Accordance to Part III - Discharge Limitations and Monitoring Parameters of the permit, some of the parameters are to be collected as grab. Based in 40 CFR Part 403.12(b)(5)(v) for Measurement of Pollutants, it states, "Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 CFR part 136 and amendments thereto." In addition, 40 CFR Part 403.12(g)(3) states, "......... Grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds."
6.2.2.1 Oil and Grease (O&G) samples should be collected as a grab. Due to its' nature, O&G will adhere to any surfaces that it comes in-contact with resulting in bias low. In Section 8.3 Sample Collection, Preservation, and Storage of EPA Method 1664 (HEM), it states, "The high probability that extractable matter may adhere to sampling equipment and result in measurements that are biased low precludes the collection of composite samples for determination of oil and grease. Therefore, samples must be collected as grab samples. If a composite measurement is required, individual grab samples collected at prescribed time intervals must be analyzed separately and the concentrations averaged. Alternatively, samples can be collected in the field and composited in the laboratory."
6.2.2.2 Hydrogen Ion (pH) should be collected as a grab sample and analyzed within 15 minutes. According to 40 CFR Part 136 Table II - Required Containers, Preservation Techniques, and Holding Times, Hydrogen Ion (pH) sample must be "analyze within 15 minutes."
6.2.2.3 Phenol is collected as a composite sample. According to Part III - Discharge Limitations and Monitoring Parameters of the Wastewater Discharge Permit under " Sampling Type" column, phenols is to be collected as "Grab."
6.2.2.4 Volatile Organic Compounds (VOCs) listed on the permit are collected as "composite." Total Toxic Organics (TTOs) is collected as "grab." These are conflicting because VOCs are a part of the TTOs. VOCs should not be collected as a composite sample using an automatic sampler. According to Section 9- Sample Collection, Preservation, and Handling of EPA Method
Page 9 of 10
Marval Industries, Inc., Mamaroneck, NY 40 CFR Parts 403 & 414 & SIU Permit
Inspection Dates: July 23-24, 2024
624, it states, " Collect the sample as a grab sample in a glass container having a total volume of at least 25-mL. Fill the sample bottles just to overflowing in such a namer that no air bubbles pass through the sample as the bottle is being filled. Seal the bottle so that no air bubbles are entrapped in it." Since VOCs is required to be collected as a composite on the permit, the alternative would be to collect multiple grab samples within a certain time intervals. The multiple grab samples would than be composited in the laboratory.
