The Delaware Hazardous Waste Management Regulations (DE WHMR) define hazardous waste based on characteristics and listings. Characteristic wastes exhibit ignitability, corrosivity, reactivity, or toxicity. Listed wastes are specifically identified by the Department of Natural Resources and Environmental Control (DNREC) as hazardous. For a waste to be regulated as hazardous, it must meet the definition of hazardous waste under these regulations. The scenario describes a waste generated from a metal finishing process. Metal finishing processes often produce wastes containing heavy metals, which are typically regulated as hazardous due to their toxicity. Specifically, waste streams from metal plating, etching, and cleaning can contain metals like chromium, cadmium, lead, and nickel, which are listed as hazardous wastes or exhibit the toxicity characteristic. The question asks about the initial determination of hazardous waste status. The primary regulatory framework in Delaware for identifying hazardous waste is found within the DE WHMR, which mirrors the federal Resource Conservation and Recovery Act (RCRA) regulations. Therefore, the initial step in determining if the waste from the metal finishing operation is hazardous involves consulting these specific Delaware regulations to see if it is listed or exhibits any of the hazardous characteristics.

The Delaware Hazardous Waste Management Regulations (7 DE Admin. Code § 1302) define hazardous waste based on characteristics and listings. A generator is an entity that produces hazardous waste. The regulations distinguish between different generator statuses: Very Small Quantity Generator (VSQG), Small Quantity Generator (SQG), and Large Quantity Generator (LQG), based on the amount of hazardous waste generated per month. A VSQG generates no more than 100 kilograms (220 pounds) of hazardous waste per month, and no more than 1 kilogram (2.2 pounds) of acutely hazardous waste per month. An SQG generates between 100 and 1,000 kilograms (220 to 2,200 pounds) of hazardous waste per month, and no more than 1 kilogram (2.2 pounds) of acutely hazardous waste per month. An LQG generates 1,000 kilograms or more of hazardous waste per month, or any amount of acutely hazardous waste. The scenario describes a facility that generates 950 kg of non-acute hazardous waste and 1.5 kg of acutely hazardous waste in a calendar month. To determine the generator status, we must consider both quantities. The 950 kg of non-acute hazardous waste places the facility in the SQG category for that type of waste. However, the generation of 1.5 kg of acutely hazardous waste exceeds the 1 kg limit for both VSQGs and SQGs. Therefore, the facility’s generator status is determined by the acutely hazardous waste threshold, classifying it as a Large Quantity Generator.

Delaware’s Hazardous Waste Management Regulations, specifically referencing 7 DE Admin. Code § 1301, establish stringent requirements for the management of hazardous waste. A key aspect is the definition and management of “Universal Waste.” Universal waste streamlines the management of certain hazardous wastes that are generated by a wide variety of facilities and are commonly generated in relatively small quantities. This category includes batteries, pesticides, mercury-containing equipment, and lamps. The intent is to reduce the regulatory burden on handlers of these specific wastes while still ensuring their proper management. Facilities that accumulate universal waste are subject to different accumulation time limits and labeling requirements compared to typical hazardous waste generators. For instance, a universal waste handler can accumulate universal waste for up to one year. Upon shipment, universal waste must be transported by a universal waste transporter to a universal waste destination facility. The regulations also specify that universal waste must be managed in a way that prevents the release of hazardous constituents to the environment. This includes ensuring containers are in good condition, kept closed, and compatible with the waste. Proper labeling is also critical, with containers needing to be clearly marked as “Universal Waste – Batteries,” “Universal waste – Pesticides,” “Universal Waste – Mercury-containing Equipment,” or “Universal Waste – Lamps,” as appropriate. The regulations aim to balance environmental protection with practical management for these commonly generated waste streams.

The Delaware Hazardous Waste Management Regulations (7 DE Admin. Code § 1302) define a “small quantity generator” (SQG) as a generator who generates no more than 1,000 kilograms (approximately 2,200 pounds) of hazardous waste per month. This threshold is crucial for determining the specific management and reporting requirements applicable to a facility. For example, an SQG is subject to less stringent storage time limits and record-keeping obligations compared to a large quantity generator. The regulations also specify that if a generator exceeds the SQG threshold in any single month, they are considered a large quantity generator for that month and must comply with the more rigorous requirements. The classification is based on the total amount of hazardous waste generated in a calendar month, excluding hazardous waste that is treated, stored, or disposed of within the generating facility. It is important for generators to accurately track their waste streams to ensure proper classification and compliance with all applicable provisions of the Delaware Hazardous Waste Management Regulations.

The Delaware Hazardous Waste Management Regulations, specifically referencing the requirements for hazardous waste generators, mandate that generators of hazardous waste must maintain records of their hazardous waste activities. These records are crucial for demonstrating compliance with the regulations, tracking waste generation, and facilitating proper management and disposal. The regulations, in alignment with federal Resource Conservation and Recovery Act (RCRA) requirements, typically require generators to retain records for a specified period. For hazardous waste manifests, the standard retention period is generally three years from the date the waste was accepted by the initial transporter. This period ensures that there is sufficient time for the waste to be tracked from generation to final disposal and for any potential issues or discrepancies to be identified and resolved. Maintaining these records is a fundamental aspect of generator responsibility under the law.

The Delaware Hazardous Waste Management Regulations, specifically under 7 DE Admin. Code § 1302, govern the management of hazardous waste. Section 1302.17 addresses the Land Disposal Restrictions (LDR). This regulation dictates that hazardous wastes must meet specific treatment standards before they can be land disposed. These treatment standards are typically based on Best Demonstrated Available Technology (BDAT). For wastes exhibiting the characteristic of ignitability, the treatment standard is generally to reduce the flash point to \( \ge 150^\circ F \) (65.6\(^\circ C\)) or to treat it via incineration. However, when a hazardous waste is mixed with a non-hazardous solid waste, the mixture is generally regulated as hazardous if the resultant mixture still exhibits a hazardous characteristic or if the original hazardous waste was listed. The “mixture rule” under RCRA (Resource Conservation and Recovery Act) and its state-level implementations, like Delaware’s, generally means that if a listed hazardous waste is mixed with any amount of non-hazardous waste, the entire mixture becomes hazardous. For characteristic wastes, if the mixture still exhibits a characteristic, it remains hazardous. In the scenario presented, the ignitable waste (D001) is mixed with a non-hazardous solid waste. Even though the intent is to dilute the ignitability, the mixture rule still applies. Therefore, the entire mixed waste stream is subject to hazardous waste regulations. Specifically, the LDR treatment standards for D001 (ignitable waste) would apply to the entire mixture before land disposal, unless an exemption or variance is obtained. The question asks about the immediate regulatory status of the mixture. Since the ignitable hazardous waste was mixed with a non-hazardous waste, the entire mixture is considered hazardous waste and must comply with all applicable hazardous waste management requirements, including LDR, unless specific delisting or treatability variances are granted, which are not indicated in the scenario. Therefore, the mixture is subject to hazardous waste management requirements.

The Delaware Hazardous Waste Management Regulations (7 DE Admin. Code § 1302) define hazardous waste based on characteristics and listings. Characteristic wastes exhibit ignitability, corrosivity, reactivity, or toxicity. Listed wastes are specifically identified by the Department of Natural Resources and Environmental Control (DNREC) as hazardous. A generator must determine if their waste is hazardous. If a waste exhibits any of the characteristic properties, it is considered hazardous. For corrosivity, a waste is hazardous if it is aqueous and has a pH less than or equal to 2 or greater than or equal to 12.5. If the waste is not aqueous, it is corrosive if it corrodes steel at a rate greater than 6.35 mm per year. Toxicity is determined by the Toxicity Characteristic Leaching Procedure (TCLP), where if the extract from the waste contains any of the regulated contaminants at or above the specified regulatory levels, the waste is hazardous. For ignitability, a liquid waste with a flash point less than 60 degrees Celsius (140 degrees Fahrenheit) is hazardous. Reactivity pertains to wastes that are unstable, react violently with water, or generate toxic gases. Generators are responsible for accurately classifying their waste streams. This classification dictates the subsequent management requirements, including storage, transportation, and disposal. Failure to properly classify and manage hazardous waste can result in significant penalties under Delaware law.

The Delaware Hazardous Waste Management Regulations, specifically under Title 7, Chapter 60, outline the requirements for hazardous waste generators. A critical aspect of these regulations pertains to the management of acutely hazardous wastes, which are subject to more stringent control measures. For a generator who produces 1,000 kilograms or more of hazardous waste in a calendar month, and who also generates more than 1 kilogram of acutely hazardous waste in a calendar month, they are classified as a large quantity generator (LQG). LQGs are subject to specific accumulation time limits. According to Delaware regulations, an LQG may accumulate hazardous waste on-site for no more than 90 days. This 90-day period begins when the first hazardous waste is generated or when the generator exceeds the threshold for a large quantity generator. Beyond this period, the waste must have been manifested and shipped off-site to a permitted treatment, storage, or disposal facility (TSDF). The regulations also mandate that the generator maintain records of the quantity of hazardous waste generated and the dates of accumulation. Failure to comply with these accumulation time limits can result in enforcement actions and penalties. The key distinction for acutely hazardous waste is that even small quantities, when combined with other hazardous wastes exceeding LQG thresholds, trigger the LQG status and its associated stringent management requirements, including the 90-day accumulation limit.

The Delaware Hazardous Waste Management Regulations, specifically under 7 DE Admin. Code § 1302, outline requirements for hazardous waste generators. A “conditionally exempt small quantity generator” (CESQG) is defined by the quantity of hazardous waste generated per month. According to the regulations, a CESQG is a generator who generates no more than 100 kilograms (approximately 220 pounds) of hazardous waste per month. This threshold is a critical distinction for determining applicable management standards, as CESQGs are subject to less stringent requirements compared to small quantity generators or large quantity generators. Understanding this specific quantity threshold is fundamental to compliance for businesses operating in Delaware that may generate hazardous waste. The regulations aim to categorize generators based on their potential impact and the volume of hazardous materials they handle, thereby tailoring regulatory oversight.

The Delaware Hazardous Waste Management Regulations, specifically referencing 7 DE Admin. Code § 1302, govern the management of hazardous waste. This section outlines the requirements for hazardous waste generators, including the identification and classification of hazardous waste. When a generator discovers that they have generated a hazardous waste that was not previously identified, they must determine if the newly discovered waste is hazardous. This determination is crucial for compliance with manifest requirements, storage limitations, and disposal obligations. The regulations require that the generator conduct a hazardous waste determination. This involves either testing the waste or using knowledge of the waste’s characteristics and the processes that generated it. If the waste exhibits any of the characteristics of hazardous waste (ignitability, corrosivity, reactivity, or toxicity) or is listed as hazardous waste, it must be managed as such. The prompt describes a scenario where a facility in Delaware, “ChemSolutions Inc.,” discovers a new waste stream from a modified process. The critical step for ChemSolutions Inc. is to perform a proper hazardous waste determination for this new stream to ensure compliance with all applicable regulations. This involves understanding the characteristics and potential listing criteria outlined in the Delaware regulations, which are largely aligned with federal RCRA requirements but may have state-specific nuances. The determination process is the foundational step before any other management practices can be implemented.

The Delaware Hazardous Waste Management Regulations, specifically referencing the requirements for generators, dictates the procedures for managing hazardous waste. A key aspect is the determination of generator status, which is based on the quantity of hazardous waste generated per calendar month. For a conditionally exempt small quantity generator (CESQG), the limit is typically less than 100 kilograms (approximately 220 pounds) of hazardous waste per month and less than 1 kilogram of acutely hazardous waste per month. In this scenario, the facility generates 95 kilograms of hazardous waste and 0.5 kilograms of acutely hazardous waste in a given month. Since both quantities are below the established thresholds for CESQG status, the facility would be classified as a CESQG. This classification exempts them from many of the more stringent management and reporting requirements applicable to larger quantity generators under Delaware law, though they must still comply with specific CESQG management standards, such as ensuring their waste is managed at a permitted hazardous waste facility or a facility that meets specific criteria. Understanding these thresholds is crucial for accurate regulatory compliance.

The Delaware Hazardous Waste Management Regulations, specifically referencing 7 DE Admin. Code § 1302, establish criteria for determining if a solid waste is a hazardous waste. A waste is presumed to be hazardous if it exhibits any of the characteristics of hazardous waste: ignitability, corrosivity, reactivity, or toxicity. For toxicity, Delaware utilizes the Toxicity Characteristic Leaching Procedure (TCLP) as outlined in 40 CFR Part 261, Subpart C, incorporated by reference. The TCLP is a simulation of the leaching that occurs when a waste is disposed of in a landfill. If the leachate from a waste sample exceeds regulatory limits for specific contaminants, the waste is classified as toxic hazardous waste. The regulation specifies a list of contaminants and their maximum allowable concentrations in the leachate. For example, if a waste, when subjected to the TCLP, yields a leachate with a concentration of lead exceeding 5.0 mg/L, it would be classified as a D008 hazardous waste due to toxicity. The regulations also detail the procedures for sampling, testing, and record-keeping associated with hazardous waste characterization. Generators are responsible for accurately determining if their waste is hazardous, and this characterization is a fundamental step in complying with all subsequent management, treatment, storage, and disposal requirements under Delaware law. Understanding the TCLP methodology and the specific contaminant thresholds is crucial for proper waste classification and management within the state.

The Delaware Hazardous Waste Management Regulations, specifically referencing 7 DE Admin. Code § 1301, outline the requirements for hazardous waste generators. A conditionally exempt small quantity generator (CESQG) in Delaware is defined by the quantity of hazardous waste generated per month. According to the regulations, a CESQG is a generator who generates no more than 100 kilograms (approximately 220 pounds) of hazardous waste in a calendar month. This classification significantly impacts the regulatory burden, allowing for less stringent storage, record-keeping, and manifesting requirements compared to larger quantity generators. Understanding these thresholds is crucial for compliance and proper waste management practices within the state. The regulations also specify that the total accumulation of hazardous waste on-site at any one time cannot exceed 1,000 kilograms (approximately 2,200 pounds) for a CESQG. Furthermore, the regulations require that CESQGs send their hazardous waste to a permitted hazardous waste facility or a recycling facility. The monthly generation limit is the primary determinant of CESQG status.

The Delaware Hazardous Waste Management Regulations, specifically under 7 DE Admin. Code § 1302, govern the management of hazardous waste. A key aspect of these regulations pertains to the identification and classification of hazardous waste. When a generator produces a waste that is not specifically listed as hazardous under the regulations (e.g., F, K, P, or U lists), they must determine if the waste exhibits any hazardous characteristics. These characteristics are ignitability, corrosivity, reactivity, and toxicity. The toxicity characteristic is determined by the Toxicity Characteristic Leaching Procedure (TCLP), outlined in 40 CFR Part 261, Subpart C, Appendix II. If the TCLP extract from a representative sample of the waste contains any of the specified contaminants at or above regulatory thresholds, the waste is classified as hazardous due to toxicity. For instance, if a waste, when subjected to TCLP, yields a leachate concentration of lead exceeding the regulatory limit of 5.0 mg/L, it is considered a D008 hazardous waste. The generator is responsible for performing this analysis or having it performed by a qualified laboratory. The correct classification ensures proper management, transportation, and disposal in accordance with federal and state requirements, preventing environmental contamination and ensuring compliance with cradle-to-grave management principles.

The Resource Conservation and Recovery Act (RCRA) establishes a framework for managing hazardous waste from its generation to its final disposal. Under RCRA, a generator is classified based on the amount of hazardous waste they produce per month. This classification dictates the specific regulatory requirements a facility must adhere to. Specifically, a large quantity generator (LQG) is defined as a facility that generates 1,000 kilograms (kg) or more of hazardous waste in a calendar month, or more than 1 kg of acute hazardous waste in a calendar month. A small quantity generator (SQG) is defined as a facility that generates between 100 kg and 1,000 kg of hazardous waste in a calendar month, or no more than 1 kg of acute hazardous waste in a calendar month. A conditionally exempt small quantity generator (CESQG) is defined as a facility that generates 100 kg or less of hazardous waste per month and no more than 1 kg of acute hazardous waste per month. These distinctions are crucial for compliance with federal and state hazardous waste regulations, including those in Delaware, which often mirrors federal standards while sometimes imposing stricter requirements. The scenario describes a facility generating 1,200 kg of hazardous waste in a month, which clearly exceeds the 1,000 kg threshold for an LQG. Therefore, the facility is regulated as a large quantity generator.

The Delaware Hazardous Waste Management Regulations (7 DE Admin. Code § 1302) define hazardous waste based on specific characteristics and listings. A waste is considered hazardous if it exhibits one or more of the characteristics of ignitability, corrosivity, reactivity, or toxicity, or if it is a listed hazardous waste. The toxicity characteristic is determined by the Toxicity Characteristic Leaching Procedure (TCLP), which simulates landfill conditions. If the leachate from a waste sample exceeds regulatory limits for certain contaminants, the waste is classified as hazardous due to toxicity. For example, under 40 CFR Part 261, Subpart C, if a waste exhibits any of the defined characteristics, it is considered hazardous. The regulations also incorporate federal hazardous waste listings, such as those found in 40 CFR § 261.31 and § 261.32, which identify specific wastes from non-specific sources (F-list), specific sources (K-list), discarded commercial chemical products (P-list and U-list), and discarded commercial chemical products, off-specification species, container residues, and spill residues thereof (P-list and U-list). Therefore, a waste generator must determine if their waste is hazardous by either testing for the characteristics or by knowing if it is a listed hazardous waste. Without specific information on the composition or origin of the waste, a definitive classification cannot be made. However, the question asks about the *primary* method for classifying a waste *not* previously identified as listed. In such cases, characteristic testing is the initial and primary step for a generator to determine if their waste is hazardous.

The Delaware Hazardous Waste Management Regulations (DE WHMR) define “characteristic hazardous waste” based on four properties: ignitability, corrosivity, reactivity, and toxicity. A waste exhibits toxicity if, using the Toxicity Characteristic Leaching Procedure (TCLP), the extract from the waste contains any of the contaminants listed in 40 CFR § 261.24 at a concentration equal to or greater than the regulatory level. For arsenic, the regulatory level is 5.0 mg/L. If a waste fails the TCLP for arsenic, it is classified as a hazardous waste due to toxicity. The question asks about a waste stream from a chemical manufacturing facility in Delaware that, when subjected to the TCLP, yields an arsenic concentration of 6.2 mg/L in the leachate. Since 6.2 mg/L is greater than the regulatory limit of 5.0 mg/L for arsenic, this waste stream is classified as a characteristic hazardous waste. Specifically, it is hazardous due to the toxicity characteristic. The generator of this waste must manage it in accordance with all applicable federal and state hazardous waste regulations, including manifesting, proper storage, transportation by licensed haulers, and disposal at a permitted Treatment, Storage, and Disposal Facility (TSDF). This classification is critical for compliance and environmental protection.

The Delaware Hazardous Waste Management Regulations, specifically referencing the requirements for hazardous waste generators, outlines distinct categories based on the quantity of hazardous waste produced per month. A Large Quantity Generator (LQG) is defined as a facility that generates 1,000 kilograms (kg) or more of hazardous waste in any single month, or more than 1 kilogram (kg) of acute hazardous waste in any single month. A Small Quantity Generator (SQG) is defined as a facility that generates between 100 kg and 1,000 kg of hazardous waste in any single month, or less than or equal to 1 kg of acute hazardous waste in any single month. Conditionally Exempt Small Quantity Generators (CESQGs) generate 100 kg or less of hazardous waste per month and do not generate acute hazardous waste or generate less than or equal to 1 kg of acute hazardous waste per month. In the scenario provided, the facility consistently generates 950 kg of hazardous waste per month and has never generated more than 0.5 kg of acute hazardous waste in any given month. Therefore, the facility’s waste generation profile aligns with the definition of a Small Quantity Generator under Delaware’s regulations. This classification dictates specific management standards, including requirements for storage, personnel training, and contingency planning, which are less stringent than those for LQGs but more rigorous than those for CESQGs. The key differentiator for this facility is the monthly generation of 950 kg, which falls squarely within the SQG threshold.

The Delaware Hazardous Waste Management Regulations (7 DE Admin. Code § 1302) establish specific requirements for the management of hazardous waste. A key aspect of these regulations pertains to the identification and classification of hazardous waste. For a solid waste to be classified as hazardous under Delaware law, it must meet certain criteria. These criteria are generally aligned with the federal Resource Conservation and Recovery Act (RCRA) definitions but may have state-specific nuances. Specifically, a waste is considered hazardous if it is listed by the Delaware Department of Natural Resources and Environmental Control (DNREC) or if it exhibits one or more hazardous characteristics: ignitability, corrosivity, reactivity, or toxicity. The toxicity characteristic is determined by the Toxicity Characteristic Leaching Procedure (TCLP), as outlined in 40 CFR Part 261, Subpart C, Appendix 11. If a solid waste exhibits any of these characteristics, it is regulated as a hazardous waste. Therefore, a waste exhibiting the characteristic of ignitability, as defined by its flash point being less than 60 degrees Celsius (140 degrees Fahrenheit), would be classified as hazardous waste in Delaware, irrespective of whether it is also listed or exhibits other characteristics.

The Delaware Hazardous Waste Management Regulations (7 DE Admin. Code § 1302) define a hazardous waste generator based on the quantity of hazardous waste produced per month. A Very Small Quantity Generator (VSQG) generates no more than 100 kilograms (approximately 220 pounds) of hazardous waste per month, or no more than 1 kilogram of acute hazardous waste per month, and accumulates no more than 1,000 kilograms of hazardous waste at any time. A Small Quantity Generator (SQG) generates more than 100 kilograms but less than 1,000 kilograms of hazardous waste per month, and accumulates no more than 6,000 kilograms of hazardous waste at any time. A Large Quantity Generator (LQG) generates 1,000 kilograms or more of hazardous waste per month, or more than 1 kilogram of acute hazardous waste per month. In this scenario, the facility generates 150 kilograms of hazardous waste in January and 200 kilograms in February. Since the monthly generation consistently exceeds the 100-kilogram threshold for a VSQG but remains below the 1,000-kilogram threshold for an LQG, and assuming they do not exceed the accumulation limits for an SQG, they would be classified as a Small Quantity Generator. The key determinant here is the monthly generation rate.

The Delaware Hazardous Waste Management Regulations (DE WHMR) define criteria for identifying hazardous waste. A waste is considered hazardous if it exhibits a characteristic of hazardous waste, or if it is listed as hazardous. The characteristic wastes are ignitability, corrosivity, reactivity, and toxicity. The toxicity characteristic is determined by the Toxicity Characteristic Leaching Procedure (TCLP). If a waste leaches any of the regulated contaminants above their regulatory levels, it is deemed toxic hazardous waste. For example, if a waste sample, when subjected to the TCLP and analyzed for lead, yields a concentration of 6 mg/L, this concentration exceeds the regulatory limit for lead, which is 5 mg/L under the Toxicity Characteristic. Therefore, this waste would be classified as hazardous due to toxicity. The regulations also specify listing procedures where specific wastes from specific sources are identified as hazardous. Generators are responsible for determining if their waste is hazardous through testing or process knowledge. Proper management of hazardous waste, including manifesting, storage, and transportation, is mandated under these regulations to protect human health and the environment.

The Delaware Hazardous Waste Management Regulations, specifically referencing 7 DE Admin. Code § 1302, establish requirements for the management of hazardous waste. A key aspect of these regulations pertains to the notification and permitting of hazardous waste treatment, storage, and disposal facilities (TSDFs). Facilities that treat hazardous waste are subject to these regulations. The generation of hazardous waste itself does not automatically trigger the stringent permitting requirements of a TSDF unless the facility is also storing, treating, or disposing of that waste in a manner that meets the regulatory definitions of these activities. Specifically, the regulations define “treatment” as any method, technique, or process designed to change the physical, chemical, or biological character or composition of any hazardous waste so as to neutralize it, render it non-hazardous, recover it, or reduce its volume. Simply holding waste for less than 90 days in a compliant manner for the purpose of accumulation before shipment to a permitted facility, without engaging in any process that alters its character, does not constitute treatment under these regulations. Therefore, a facility that only generates hazardous waste and stores it temporarily for shipment, without performing any treatment processes, is not classified as a TSDF and is not subject to the full permitting requirements for TSDFs under this specific section of the Delaware regulations. The threshold for TSDF permitting is tied to the specific management activities undertaken with the waste, not solely the generation of it.

The Delaware Hazardous Waste Management Regulations, specifically referencing 7 DE Admin. Code § 1302, outline the requirements for hazardous waste generators. A key aspect is the determination of generator status based on the quantity of hazardous waste produced per month. A “Conditionally Exempt Small Quantity Generator” (CESQG) is defined as a generator who produces no more than 100 kilograms (approximately 220 pounds) of hazardous waste per month, or no more than 1 kilogram of acute hazardous waste per month. Furthermore, a CESQG must not accumulate more than 1,000 kilograms (approximately 2,200 pounds) of hazardous waste at any time. If a generator exceeds any of these thresholds, they are reclassified to a higher generator category, such as a small quantity generator or a large quantity generator, and must comply with the more stringent requirements associated with those categories. This reclassification is crucial for ensuring appropriate management and oversight of hazardous waste based on its potential environmental and health risks, which are directly correlated with the volume generated. The regulations aim to provide a tiered approach to hazardous waste management, with less stringent requirements for those generating minimal amounts and progressively stricter controls for larger volume generators.

The Delaware Hazardous Waste Management Regulations, specifically those pertaining to the generation of hazardous waste, establish strict criteria for identifying and classifying waste streams. A generator is classified based on the quantity of hazardous waste produced per calendar month. For a small quantity generator (SQG), this threshold is between 100 kilograms (kg) and 1,000 kg of hazardous waste per month, or less than or equal to 1 kg of acute hazardous waste per month. A large quantity generator (LQG) generates 1,000 kg or more of hazardous waste per month, or more than 1 kg of acute hazardous waste per month. An even smaller quantity generator (VSQG) generates 100 kg or less of non-acute hazardous waste per month, or less than or equal to 1 kg of acute hazardous waste per month. The scenario describes a facility generating 850 kg of hazardous waste and 0.5 kg of acute hazardous waste in a calendar month. To determine the generator status, we must consider both waste types. The 850 kg of hazardous waste clearly places the facility above the VSQG threshold. Comparing 850 kg to the SQG threshold of 100 kg to 1,000 kg, it falls within this range. The 0.5 kg of acute hazardous waste is below the 1 kg threshold for acute hazardous waste, which would trigger LQG status if exceeded. Therefore, the facility meets the criteria for a small quantity generator due to the volume of non-acute hazardous waste produced, even though the acute hazardous waste volume does not elevate it to LQG status. The regulatory framework in Delaware, mirroring federal RCRA Subtitle C, emphasizes these quantity-based classifications for determining applicable management standards.

The Delaware Hazardous Waste Management Regulations (7 DE Admin. Code § 1302) establish requirements for the management of hazardous waste. Specifically, Part 262 of these regulations, which aligns with the federal Resource Conservation and Recovery Act (RCRA) Subtitle C, details the standards applicable to generators of hazardous waste. Generators are classified based on the amount of hazardous waste they produce per month. A very small quantity generator (VSQG) is defined as a generator who generates no more than 100 kilograms (220 pounds) of hazardous waste per month, or no more than 1 kilogram (2.2 pounds) of acute hazardous waste per month, or accumulates no more than 1,000 kilograms (2,200 pounds) of hazardous waste at any time. Small quantity generators (SQGs) generate between 100 and 1,000 kilograms of hazardous waste per month. Large quantity generators (LQGs) generate 1,000 kilograms or more of hazardous waste per month. The regulatory requirements, including manifest requirements, storage limits, and personnel training, increase in stringency with the generator category. Understanding these thresholds is crucial for compliance, as exceeding a threshold can immediately change a facility’s regulatory obligations. For instance, a facility that consistently generates 90 kg of hazardous waste per month and 0.5 kg of acute hazardous waste per month would be classified as a VSQG. If, in a particular month, their hazardous waste generation increased to 150 kg, they would then be subject to the regulations for a small quantity generator for that month and potentially subsequent months, depending on their ongoing generation rates and accumulation. This transition necessitates immediate adherence to the more stringent requirements for SQGs.

The Delaware Hazardous Waste Management Regulations, specifically referencing 7 DE Admin. Code § 1302, outline requirements for the management of hazardous waste. When a generator determines that a waste material exhibits a characteristic of hazardous waste, they must assign a specific EPA hazardous waste code. For ignitability, the characteristic is defined by a flash point of less than 60 degrees Celsius (140 degrees Fahrenheit). The EPA code for ignitable hazardous waste, unless it is a liquid that is an oxidizer or contains less than 24% alcohol by volume, is D001. This code signifies that the waste poses a fire hazard and requires specific management practices to prevent ignition. The regulations mandate that generators properly identify, classify, and manage hazardous wastes according to these codes to ensure environmental protection and compliance with federal and state laws. Understanding these characteristic codes is fundamental for accurate hazardous waste characterization and subsequent management protocols, including storage, transportation, and disposal. The intent behind assigning D001 is to alert handlers to the potential for spontaneous combustion or rapid fire spread, necessitating appropriate containment and handling procedures.

The Delaware Hazardous Waste Management Regulations, specifically referencing the generator status classifications, establish different requirements based on the quantity of hazardous waste produced per month. A Very Small Quantity Generator (VSQG) is defined as a facility that generates no more than 100 kilograms (approximately 220 pounds) of hazardous waste per calendar month. This classification is crucial as it dictates the regulatory burden, including storage limits, manifest requirements, and disposal options. Understanding these thresholds is fundamental to compliance within Delaware’s regulatory framework for hazardous waste management. The distinction between VSQGs, Small Quantity Generators (SQGs), and Large Quantity Generators (LQGs) hinges directly on these monthly generation rates, with each category facing progressively stringent oversight. Therefore, a facility generating 95 kilograms of hazardous waste in a given month falls squarely within the VSQG category.

The Delaware Hazardous Waste Management Regulations, specifically under 7 DE Admin. Code § 1301, address the management of hazardous waste. A key aspect of these regulations pertains to the identification and classification of hazardous waste. When a solid waste exhibits one or more hazardous characteristics, it is deemed a hazardous waste. These characteristics are ignitability, corrosivity, reactivity, and toxicity. The toxicity characteristic is determined through the Toxicity Characteristic Leaching Procedure (TCLP), which simulates leaching in a landfill. If the leachate concentration of specific constituents exceeds regulatory limits, the waste is classified as toxic hazardous waste. For the scenario presented, the waste is identified as exhibiting the characteristic of toxicity due to exceeding the regulatory limit for lead in the TCLP test. This classification mandates that the waste be managed in accordance with all applicable hazardous waste regulations in Delaware, including proper manifesting, storage, transportation, and disposal at a permitted hazardous waste facility. The regulations do not differentiate management based on the specific characteristic unless other criteria are met; the presence of any characteristic triggers full hazardous waste management requirements. Therefore, the waste is classified as a toxic characteristic hazardous waste.

The Delaware Hazardous Waste Management Regulations, specifically under 7 DE Admin. Code § 1302, define the requirements for hazardous waste generators. A key aspect is the accumulation time limits for different generator statuses. For a large quantity generator (LQG), hazardous waste can be accumulated on-site for up to 90 days in a calendar month without a permit, provided it is stored in approved containers or tanks and meets specific management standards. Beyond this 90-day period, the generator must either have the waste transported off-site to a permitted treatment, storage, and disposal facility (TSDF) or obtain a permit for on-site storage. The regulations also stipulate that generators must manifest their hazardous waste shipments when they leave the site. If a generator accumulates waste for longer than 90 days, they are effectively operating as a storage facility and would need to comply with the permitting requirements for such operations. Therefore, exceeding the 90-day accumulation limit without proper authorization or shipment would place the generator in violation of the regulations, requiring them to either ship the waste or seek a permit.

The Delaware Hazardous Waste Management Regulations (DE WHMR) define specific requirements for the management of hazardous waste, including the classification and handling of characteristic wastes. A waste exhibits the characteristic of ignitability if it is a liquid that has a flash point of less than 60 degrees Celsius (140 degrees Fahrenheit). It can also be a non-liquid solid that is capable of causing fire through friction, absorption of moisture, or spontaneous chemical changes and, when ignited, burns so vigorously and persistently as to create a hazard. Furthermore, ignitable compressed gases and oxidizers are also classified as ignitable hazardous wastes. The regulations, specifically referencing 7 DE Admin. Code § 1302, detail these criteria. For a liquid waste to be classified as ignitable, its flash point must be below the threshold. If a waste has a flash point of 55 degrees Celsius, it meets the criterion for ignitability as a liquid hazardous waste under Delaware law. This classification mandates specific storage, transportation, and disposal procedures to mitigate the risks associated with flammable materials. Understanding these characteristics is fundamental for any entity generating or managing hazardous waste within Delaware, ensuring compliance with state environmental protection mandates.
