The Hawaii Revised Statutes (HRS) Chapter 342J, specifically the “Hazardous Waste Management” section, outlines the regulatory framework for hazardous waste in the state. Under these statutes, a generator of hazardous waste is defined by the quantity of hazardous waste produced within a calendar month. The categories are typically Small Quantity Generators (SQGs) and Large Quantity Generators (LQGs), with specific thresholds determining classification. For Hawaii, the definition aligns closely with federal EPA definitions under 40 CFR Part 261 and 262. A generator is classified as a large quantity generator if they generate 1,000 kilograms (kg) or more of hazardous waste in a single calendar month, or more than 1 kilogram (kg) of acute hazardous waste in a single calendar month. The question tests the understanding of these quantity-based definitions as they apply to the state’s regulatory structure, which aims to manage hazardous waste effectively based on the potential risk posed by the volume and type of waste generated. The specific threshold for large quantity generators in Hawaii, consistent with federal standards, is 1,000 kg of hazardous waste per month.

The Hawaii Administrative Rules (HAR) Chapter 11-260, specifically the sections pertaining to the definition of hazardous waste and the generator status, are crucial for determining regulatory obligations. Under HAR 11-260-3, a solid waste is classified as hazardous if it exhibits one or more characteristics of ignitability, corrosivity, reactivity, or toxicity, or if it is listed as a hazardous waste. A generator is classified based on the quantity of hazardous waste produced per month. Small Quantity Generators (SQGs) in Hawaii are defined as those who produce between 100 and 1,000 kilograms (approximately 220 to 2,200 pounds) of hazardous waste per calendar month. Large Quantity Generators (LQGs) produce 1,000 kilograms or more per month. Conditionally Exempt Small Quantity Generators (CESQGs) produce 100 kilograms or less per month. The scenario describes a facility that produces 950 kilograms of hazardous waste in a month. This quantity falls within the range of 100 to 1,000 kilograms, thus classifying the facility as a Small Quantity Generator under Hawaii’s hazardous waste regulations. This classification dictates specific requirements for storage, record-keeping, and reporting, which are less stringent than those for LQGs but more rigorous than for CESQGs. Understanding these quantity thresholds is fundamental to compliance with Hawaii’s hazardous waste management program, which aligns with the federal Resource Conservation and Recovery Act (RCRA) but may have state-specific nuances.

The Hawaii Revised Statutes (HRS) Chapter 342J, the Hawaii Hazardous Waste Law, establishes a comprehensive regulatory framework for hazardous waste management. Specifically, HRS § 342J-3(a) mandates that the Department of Health (DOH) adopt rules to implement the provisions of the chapter. These rules are crucial for defining hazardous waste, establishing standards for generation, treatment, storage, and disposal, and outlining requirements for permitting, record-keeping, and reporting. The DOH’s authority to adopt rules is a foundational element that enables the practical enforcement and administration of the hazardous waste program in Hawaii, ensuring compliance with both state and federal regulations, such as the Resource Conservation and Recovery Act (RCRA) which Hawaii has authorized to implement. The adoption of rules provides the specific operational details and procedural requirements that generators, transporters, and treatment, storage, and disposal facilities (TSDFs) must follow to manage hazardous waste safely and in an environmentally sound manner within the state. Without these administrative rules, the broad mandates of the statute would lack the necessary detail for effective implementation and oversight by the DOH.

The Hawaii Revised Statutes (HRS) Chapter 342J, specifically concerning hazardous waste management, mandates a comprehensive cradle-to-grave system for tracking and controlling hazardous waste. This system is designed to protect public health and the environment. A key component of this system is the manifest, a document that accompanies hazardous waste from the point of generation to its final disposal. HRS §342J-4(a) outlines the duties of the department, which include establishing and implementing a hazardous waste management program consistent with federal regulations under the Resource Conservation and Recovery Act (RCRA). Federal regulations, such as 40 CFR Part 262, Subpart B, detail the requirements for generators to use a manifest. In Hawaii, this translates to specific procedures for preparing, using, and retaining manifests for hazardous waste shipments. The manifest serves as a legal record, ensuring that waste is transported by licensed haulers to permitted treatment, storage, or disposal facilities (TSDFs). It is crucial for demonstrating compliance and for tracing the movement of hazardous materials. The Department of Health is responsible for enforcing these provisions, and failure to properly use and retain manifests can result in penalties. The specific requirements for manifest content, distribution, and retention are detailed in Hawaii Administrative Rules (HAR) Chapter 11-261. Generators are required to maintain copies of manifests for at least three years from the date the waste was accepted by the initial transporter. This period is a standard practice in hazardous waste management to allow for audits and investigations.

The Hawaii Revised Statutes (HRS) Chapter 342J, the Hawaii Hazardous Waste Management Act, establishes a comprehensive framework for the management of hazardous waste within the state. This act, along with its implementing regulations found in the Hawaii Administrative Rules (HAR) Chapter 11-261, outlines the responsibilities of hazardous waste generators, transporters, and treatment, storage, and disposal facility (TSDF) operators. A key aspect of this regulatory scheme is the concept of “cradle-to-grave” management, ensuring that hazardous waste is tracked and managed from its point of generation to its final disposition. The Department of Health is the primary regulatory agency overseeing these activities. Generators are classified based on the amount of hazardous waste they produce monthly, with different requirements applying to large quantity generators, small quantity generators, and conditionally exempt small quantity generators. Transporters must comply with manifest requirements and specific operational standards. TSDFs are subject to rigorous permitting, design, operation, and closure requirements. The law also addresses emergency preparedness and response, as well as public participation in the regulatory process. Understanding the interplay between federal regulations, such as the Resource Conservation and Recovery Act (RCRA), and Hawaii’s specific statutory and administrative rules is crucial for compliance. Hawaii’s regulations often incorporate federal standards but may also include more stringent or unique provisions tailored to the state’s unique environmental context, such as its island geography and sensitive ecosystems.

The Hawaii Revised Statutes (HRS) Chapter 342J, also known as the Hazardous Waste Management Act, establishes the framework for managing hazardous waste within the state. This includes provisions for the identification, generation, transportation, treatment, storage, and disposal of hazardous waste. A key aspect of this law is the requirement for generators of hazardous waste to obtain an identification number from the Department of Health. This identification number is crucial for tracking hazardous waste from its point of generation to its final disposition, ensuring compliance with federal and state regulations. Generators are responsible for determining if their waste is hazardous, managing it in an environmentally sound manner, and reporting its management. The law also outlines penalties for non-compliance, which can include fines and other enforcement actions. Understanding the specific requirements for generators, including the process of obtaining an EPA identification number and the ongoing responsibilities associated with hazardous waste management, is fundamental for any entity handling such materials in Hawaii. The question tests the understanding of the initial step a generator must take to legally manage hazardous waste in Hawaii, which is obtaining the necessary identification number.

The Hawaii Revised Statutes (HRS) Chapter 342J, the Hawaii Hazardous Waste Management Act, establishes a comprehensive framework for the management of hazardous waste within the state. This act, along with its implementing rules, such as the Hawaii Administrative Rules (HAR) Chapter 11-261, governs all aspects of hazardous waste, from generation to disposal. A key element of this regulatory scheme is the requirement for generators to properly identify and manage their hazardous waste. The definition of a hazardous waste generator is crucial, as it dictates the specific regulatory obligations a facility must adhere to. HRS §342J-2 defines a “generator” as “any person who generates hazardous waste or whose act first causes a waste to become subject to regulation under this chapter.” This definition is broad and encompasses any entity that produces hazardous waste, regardless of the quantity. The Act further distinguishes between different categories of generators based on the volume of hazardous waste produced per month, which triggers varying levels of compliance requirements, including manifesting, record-keeping, and storage limitations. Understanding this foundational definition is paramount for any entity operating within Hawaii to ensure compliance with the state’s stringent hazardous waste management laws, which are designed to protect public health and the environment from the risks associated with hazardous materials.

The Hawaii Revised Statutes (HRS) Chapter 342J, the Hawaii Hazardous Waste Control Act, establishes the framework for managing hazardous waste within the state. A key aspect of this law is the definition of a “generator” and their responsibilities. According to HRS §342J-3, a generator is any person whose act or process produces hazardous waste or whose first onshore treatment, storage, or disposal of hazardous waste. This definition is crucial for determining who is subject to the stringent requirements of hazardous waste management, including record-keeping, manifesting, and proper disposal. The law specifically addresses small quantity generators and large quantity generators, with different regulatory thresholds based on the amount of hazardous waste produced per month. For instance, a large quantity generator is typically defined as a facility that produces 1,000 kilograms or more of hazardous waste per month, or 1 kilogram or more of acutely hazardous waste per month. Understanding these thresholds and the fundamental definition of a generator is paramount for compliance. The question probes the understanding of this foundational definition by presenting a scenario involving waste production and asking for the correct classification based on the law’s intent.

The Hawaii Administrative Rules (HAR) Chapter 11-260, specifically the sections pertaining to the identification and management of hazardous waste, outline the responsibilities of generators. When a facility in Hawaii generates a waste that is not explicitly listed as hazardous by the U.S. Environmental Protection Agency (EPA) or the State of Hawaii, the generator must determine if the waste exhibits any of the hazardous characteristics defined in HAR Section 11-260-003. These characteristics include ignitability, corrosivity, reactivity, and toxicity. The toxicity characteristic is determined through testing using the Toxicity Characteristic Leaching Procedure (TCLP) as described in HAR Section 11-260-003(d). If the TCLP test results for specific constituents exceed the regulatory thresholds, the waste is classified as hazardous. For instance, if a waste stream from a manufacturing process in Honolulu, Hawaii, is tested and the TCLP analysis reveals a lead concentration of 8 mg/L, which exceeds the federal and state regulatory limit of 5 mg/L for the toxicity characteristic for lead, then that waste would be considered hazardous. This determination triggers the full set of hazardous waste management requirements under HAR Chapter 11-260, including proper storage, labeling, manifesting, and disposal at a permitted treatment, storage, or disposal facility. The generator bears the ultimate responsibility for making this determination accurately.

The Hawaii Administrative Rules (HAR) Chapter 11-261, specifically regarding hazardous waste management, outlines requirements for generators. A key aspect is the determination of generator status, which dictates the regulatory obligations. For a large quantity generator (LQG), the threshold is generating 1,000 kilograms (kg) or more of hazardous waste per month, or more than 1 kg of acute hazardous waste per month. Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month, or up to 1 kg of acute hazardous waste per month. Very small quantity generators (VSQGs) generate 100 kg or less of hazardous waste per month. The scenario describes a facility in Hawaii that produces 1,100 kg of hazardous waste and 0.5 kg of acute hazardous waste in a given month. To determine the generator status, we must consider both waste streams. The 1,100 kg of hazardous waste clearly exceeds the 1,000 kg threshold for an LQG. While the 0.5 kg of acute hazardous waste is below the 1 kg threshold for acute hazardous waste, the presence of the larger volume of non-acute hazardous waste is determinative. Therefore, the facility is classified as a large quantity generator. This classification triggers the most stringent regulatory requirements under HAR Chapter 11-261 and federal RCRA regulations as adopted by Hawaii, including manifest requirements, storage limitations, personnel training, and emergency preparedness. Understanding these thresholds is fundamental for compliance and preventing environmental harm.

The Hawaii Revised Statutes (HRS) Chapter 342J, specifically the Hawaii Administrative Rules (HAR) Chapter 11-261, govern hazardous waste management. A key aspect of this regulation is the identification and management of hazardous waste. When a generator determines that a solid waste is not a hazardous waste, they must keep records of their determination. This record-keeping requirement is crucial for demonstrating compliance and for future reference by regulatory agencies. The regulations require that these records be maintained for a minimum period. For generators who are not subject to the full requirements of a large quantity generator or small quantity generator, but still produce waste that might be hazardous, the period for retaining records of non-hazardous waste determinations is generally three years from the date the waste was last sent to the TSDF or otherwise disposed of. This aligns with the general record-retention period for many hazardous waste regulations, including those under the federal Resource Conservation and Recovery Act (RCRA), which Hawaii’s program is largely based upon. The purpose of this retention period is to allow for potential audits and investigations by the Department of Health.

Hawaii’s hazardous waste management program is primarily governed by the Hawaii Revised Statutes (HRS) Chapter 342J and the Hawaii Administrative Rules (HAR) Title 11, Chapter 261. These regulations establish a framework for identifying, managing, and disposing of hazardous waste, aligning with the federal Resource Conservation and Recovery Act (RCRA) but with state-specific nuances. A key aspect of this framework involves the generator’s responsibility for accurately classifying and managing their waste. For instance, if a facility in Hawaii generates a waste stream that exhibits characteristics of ignitability, corrosivity, reactivity, or toxicity, or if it is a listed hazardous waste under HAR Section 11-261-3, it must be managed as hazardous waste. The determination of whether a waste is hazardous is a critical first step. This involves consulting the criteria outlined in HAR Section 11-261-3 and potentially conducting laboratory analysis. Once classified, the generator must comply with requirements related to accumulation time, container management, labeling, manifest preparation for off-site shipment, and record-keeping, all as detailed within HAR Chapter 261. The specific requirements can vary based on the quantity of hazardous waste generated per month, categorizing generators into different tiers (e.g., very small quantity generators, small quantity generators, large quantity generators), each with distinct regulatory obligations. The state’s program emphasizes cradle-to-grave management, meaning responsibility extends from the point of generation to final disposal. The Department of Health is the primary regulatory agency overseeing these programs in Hawaii.

The Hawaii Administrative Rules (HAR) Chapter 11-260, specifically regarding hazardous waste management, outlines stringent requirements for generators. When a generator accumulates hazardous waste on-site for more than 90 days but less than 180 days, they are classified as a “transitional hazardous waste generator.” This classification triggers specific regulatory obligations, including the need for a written contingency plan and proper personnel training, as mandated by HAR section 11-260-013. The accumulation time limit is a critical factor in determining the generator status and associated compliance duties. Exceeding the 180-day limit without a permit would typically result in a violation, as it implies the facility is operating as a storage facility without the necessary authorization. Therefore, understanding the precise timeframes for on-site accumulation is fundamental to maintaining compliance with Hawaii’s hazardous waste regulations.

The Hawaii Administrative Rules (HAR) Chapter 11-260, specifically Subchapter 3, outlines the requirements for hazardous waste generator status. A large quantity generator (LQG) is defined as a generator who generates 1,000 kilograms (kg) or more of hazardous waste in a calendar month, or accumulates a total of 6,000 kg or more of hazardous waste at any one time. A small quantity generator (SQG) is defined as a generator who generates 100 kg or more but less than 1,000 kg of hazardous waste in a calendar month, or accumulates a total of 1,000 kg or more but less than 6,000 kg of hazardous waste at any one time. A conditionally exempt small quantity generator (CESQG) generates 100 kg or less of hazardous waste in a calendar month, or accumulates a total of 1,000 kg or less of hazardous waste at any one time. In this scenario, the facility in Honolulu, Hawaii, generated 950 kg of hazardous waste in January and 1,100 kg in February. For January, the facility falls within the SQG category as the generation is between 100 kg and 1,000 kg. For February, the generation of 1,100 kg exceeds the 1,000 kg threshold for an LQG. Therefore, the facility’s generator status changes from SQG to LQG between January and February. The question asks about the generator status in February. Since the facility generated 1,100 kg in February, it is classified as a large quantity generator for that month according to HAR 11-260.3.

The Hawaii Administrative Rules (HAR) Chapter 11-261, specifically the sections pertaining to hazardous waste generator status, define the criteria for different generator categories based on the quantity of hazardous waste generated per month. A conditionally exempt small quantity generator (CESQG) is an entity that generates no more than 100 kilograms (kg) of hazardous waste per month, and no more than 1 kilogram (kg) of acutely hazardous waste per month. Furthermore, a CESQG must not accumulate more than 1,000 kg of hazardous waste at any time. The scenario describes a facility in Hawaii that generates 90 kg of hazardous waste and 0.5 kg of acutely hazardous waste in a calendar month. This quantity falls within the limits for a CESQG. The key factor is the *monthly* generation rate and the total accumulation limit. Since the generation rates are below the 100 kg and 1 kg thresholds respectively, and assuming the total accumulation does not exceed 1,000 kg, the facility qualifies as a CESQG under HAR 11-261. This classification carries specific regulatory obligations, such as the requirement to use a manifest for off-site shipment of hazardous waste, but it also offers certain exemptions from more stringent requirements applicable to larger quantity generators. The question probes the understanding of these specific generation thresholds as defined by Hawaii’s hazardous waste regulations.

The Hawaii Administrative Rules (HAR) Chapter 11-261, specifically concerning hazardous waste management, outlines the requirements for hazardous waste generators. For a conditionally exempt small quantity generator (CESQG) in Hawaii, the key criterion for maintaining this status is the amount of hazardous waste generated per month. According to HAR 11-261-105(a)(1), a CESQG is a generator who generates less than 100 kilograms (approximately 220 pounds) of hazardous waste in a calendar month. This threshold is critical for determining applicable regulatory requirements, including storage limits, manifest procedures, and personnel training. Exceeding this monthly generation limit, even for a single month, would cause the generator to lose its CESQG status and be regulated as a small quantity generator or a large quantity generator, depending on the amount generated, and thus be subject to more stringent requirements under HAR Chapter 11-261. The scenario provided describes a facility that has consistently generated 90 kilograms of hazardous waste per month. This amount falls below the 100-kilogram threshold. Therefore, the facility continues to qualify as a CESQG in Hawaii, provided no other disqualifying conditions are met, such as exceeding specific accumulation time limits or managing acutely hazardous waste in quantities that would trigger CESQG ineligibility under HAR 11-261-105(b). The calculation simply confirms that 90 kg is less than 100 kg.

The question probes the understanding of Hawaii’s specific regulatory approach to hazardous waste management, particularly concerning the definition of a “generator” and the associated responsibilities. Hawaii Revised Statutes (HRS) Chapter 342J, the primary legislation governing hazardous waste, along with its administrative rules, such as the Hawaii Administrative Rules (HAR) Chapter 11-260, establish these definitions. A key aspect of hazardous waste regulation is the tiered system of generator categories, which dictates the level of regulatory oversight and compliance obligations. These categories are typically based on the quantity of hazardous waste generated per month. For instance, a large quantity generator (LQG) in Hawaii, as defined by HAR 11-260-4, is a generator who produces 1,000 kilograms (kg) or more of hazardous waste per month, or more than 1 kg of acute hazardous waste per month. A small quantity generator (SQG) generates between 100 kg and 1,000 kg of hazardous waste per month, or less than or equal to 1 kg of acute hazardous waste per month. Conditionally exempt small quantity generators (CESQGs) generate 100 kg or less of hazardous waste per month. The scenario describes a facility in Honolulu that consistently produces 850 kg of hazardous waste monthly, and on one occasion, 1.2 kg of a specific hazardous waste classified as acutely hazardous. This dual generation rate places the facility into the category that triggers the most stringent requirements. Since the facility generates 850 kg per month, which falls between 100 kg and 1,000 kg, it would typically be classified as a small quantity generator. However, the generation of 1.2 kg of acutely hazardous waste per month exceeds the 1 kg threshold for acutely hazardous waste, which would classify it as a large quantity generator for that specific waste stream, and therefore subject to the most stringent regulations applicable to LQGs. The regulations in Hawaii, mirroring federal RCRA regulations, often categorize a generator based on the highest threshold met. Therefore, the facility must comply with the requirements for a large quantity generator. This includes obtaining an EPA identification number, adhering to storage time limits, manifesting shipments, meeting personnel training requirements, and complying with specific contingency plan and emergency preparedness standards. The other options represent classifications that do not accurately reflect the combined generation rates and the specific classification of acutely hazardous waste as stipulated in Hawaii’s regulatory framework.

The Hawaii Revised Statutes (HRS) Chapter 342J, known as the “Hazardous Waste Management Act,” establishes the framework for managing hazardous waste within the state. This act, along with its implementing rules, such as the Hawaii Administrative Rules (HAR) Title 11, Chapter 261, “Hazardous Waste Management,” outlines the responsibilities of hazardous waste generators, transporters, and treatment, storage, and disposal facilities (TSDFs). A key aspect of this regulatory scheme is the definition of a hazardous waste generator, which is determined by the quantity of hazardous waste produced within a calendar month. Hawaii adopts the generator categories established by the U.S. Environmental Protection Agency (EPA) under the Resource Conservation and Recovery Act (RCRA), but with specific state-level modifications. Specifically, Hawaii defines a large quantity generator (LQG) 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 between 1 kg and 1,000 kg of acute hazardous waste in a calendar month. Facilities generating 100 kg or less of hazardous waste in a calendar month, and no acute hazardous waste, are considered conditionally exempt small quantity generators (CESQGs). The question asks about a facility generating 950 kg of hazardous waste and 0.5 kg of acute hazardous waste in a calendar month. This scenario places the facility squarely within the definition of a small quantity generator, as it exceeds the 100 kg threshold for hazardous waste and does not meet the 1 kg threshold for acute hazardous waste that would elevate it to LQG status. Therefore, the facility must comply with the regulations applicable to SQGs in Hawaii, which are less stringent than those for LQGs but more stringent than those for CESQGs.

The Hawaii Revised Statutes (HRS) Chapter 342J, known as the Hawaii Hazardous Waste Management Act, establishes a comprehensive framework for the management of hazardous waste within the state. This act is largely modeled after the federal Resource Conservation and Recovery Act (RCRA). A critical aspect of this law is the definition of hazardous waste, which is determined by specific characteristics or by being listed as a hazardous waste. Characteristic hazardous wastes are those that exhibit ignitability, corrosivity, reactivity, or toxicity. The toxicity characteristic is assessed through the Toxicity Characteristic Leaching Procedure (TCLP). If a waste material, when subjected to the TCLP, leaches certain contaminants above specified regulatory levels, it is classified as a hazardous waste. For instance, under federal regulations, which Hawaii generally follows, if a waste exhibits a pH below 2.0 or above 12.5, it is considered corrosive. If it contains specific heavy metals like lead or cadmium above certain TCLP limits, it is also deemed hazardous. Furthermore, the Act mandates that generators of hazardous waste must comply with specific requirements regarding identification, storage, transportation, and disposal. The Department of Health (DOH) is the primary regulatory agency responsible for implementing and enforcing these provisions. Proper classification is the foundational step for all subsequent management requirements, ensuring that hazardous waste is handled in a manner that protects public health and the environment. The scenario described, where a waste material exhibits a pH of 1.5, directly triggers the corrosivity characteristic as defined by both federal RCRA regulations and, by extension, Hawaii’s hazardous waste management program, making it a hazardous waste.

The Hawaii Administrative Rules (HAR) Chapter 11-261, specifically sections pertaining to the definition of hazardous waste, are crucial for classifying waste streams. Under these rules, a waste is considered hazardous if it is listed by the U.S. Environmental Protection Agency (EPA) or if it exhibits one or more characteristics of hazardous waste: ignitability, corrosivity, reactivity, or toxicity. The toxicity characteristic is determined by the Toxicity Characteristic Leaching Procedure (TCLP), which simulates leaching in a landfill. If the concentration of any of the specified contaminants in the leachate exceeds the regulatory limits, the waste is deemed toxic. For instance, if a waste exhibits a pH below 2.0, it is considered corrosive. Similarly, if it has a flash point below 140 degrees Fahrenheit (\(60^\circ C\)), it is ignitable. Reactivity involves instability, potential for violent chemical change, or generation of toxic gases. The specific scenario of a waste generator in Hawaii must consult HAR Chapter 11-261 and potentially federal Resource Conservation and Recovery Act (RCRA) regulations, which Hawaii often adopts by reference, to accurately determine if their waste meets any of these criteria. The key is to understand the regulatory definitions and testing procedures outlined in these rules to ensure proper hazardous waste management and compliance within Hawaii.

The Hawaii Administrative Rules (HAR) Chapter 11-260, specifically the section on hazardous waste generator status, defines the criteria for small quantity generators (SQGs) and large quantity generators (LQGs). A generator is classified based on the amount of hazardous waste produced per month. For SQGs, the limit is between 100 kilograms and 1,000 kilograms of hazardous waste per month, or less than 1 kilogram of acutely hazardous waste per month. LQGs generate 1,000 kilograms or more of hazardous waste per month, or more than 1 kilogram of acutely hazardous waste per month. If a facility generates 950 kg of hazardous waste and 0.5 kg of acutely hazardous waste in a month, it must be evaluated against both criteria. The 950 kg of hazardous waste falls within the SQG range (100-1000 kg). However, the 0.5 kg of acutely hazardous waste is below the 1 kg threshold for LQG status concerning acutely hazardous waste. Therefore, the generator’s status is determined by the non-acutely hazardous waste. Since 950 kg is less than 1000 kg, the facility qualifies as a small quantity generator for that month. This classification dictates specific regulatory requirements for storage, manifesting, and reporting, as outlined in HAR Chapter 11-260. Understanding these thresholds is crucial for compliance and avoiding penalties under Hawaii’s hazardous waste management program, which aligns with the federal Resource Conservation and Recovery Act (RCRA) framework but includes state-specific nuances.

The Hawaii Administrative Rules (HAR) Chapter 11-261, specifically the sections pertaining to hazardous waste generator status, dictate the requirements for businesses that produce hazardous waste. For large quantity generators (LQGs), the regulations impose stringent management standards, including specific accumulation time limits and manifest requirements. Small quantity generators (SQGs) and conditionally exempt small quantity generators (CESQGs) have less stringent requirements, with CESQGs facing the least regulatory burden. A key differentiator for CESQGs is the quantity of hazardous waste they generate per month. In Hawaii, a CESQG is defined as a generator who generates no more than 100 kilograms (approximately 220 pounds) of hazardous waste per month, and no more than 1 kilogram (approximately 2.2 pounds) of acute hazardous waste per month, and does not accumulate more than 1,000 kilograms (approximately 2,200 pounds) of hazardous waste at any time. The question asks about the maximum monthly generation limit for a CESQG in Hawaii. Therefore, the correct threshold for hazardous waste generation per month for a CESQG in Hawaii is 100 kilograms.

The Hawaii Administrative Rules (HAR) Chapter 11-261, specifically the sections pertaining to hazardous waste generator status and manifest requirements, dictates the responsibilities for managing hazardous waste. A large quantity generator (LQG) in Hawaii, as defined by HAR Section 11-261-103, is subject to more stringent requirements than a small quantity generator (SQG) or a very small quantity generator (VSQG). These requirements include specific accumulation time limits, personnel training, and emergency preparedness. When a generator ceases to operate and has accumulated hazardous waste on-site, they must ensure that all such waste is properly managed and removed before closure. The manifest system, governed by HAR Section 11-261-111, is a crucial tracking document for hazardous waste from its point of generation to its final disposal. A generator must ensure that all hazardous waste manifests are properly completed and signed by all parties involved, including the generator, transporter, and treatment, storage, and disposal facility (TSDF). Upon closure, the generator must retain these manifests for a specified period, typically three years, as per HAR Section 11-261-112, to demonstrate proper management and disposal of all hazardous waste generated during their operational period. Failure to do so can result in penalties and liabilities. Therefore, the generator’s responsibility extends beyond the active operational phase to encompass the complete and documented closure of all hazardous waste management activities.

The Hawaii Administrative Rules (HAR) Chapter 11-260, specifically sections pertaining to hazardous waste generator status, define the criteria for determining if a facility is a conditionally exempt small quantity generator (CESQG), a small quantity generator (SQG), or a large quantity generator (LQG). These classifications are primarily based on the maximum amount of hazardous waste generated per calendar month. For a facility to be classified as a CESQG, it must generate no more than 100 kilograms (approximately 220 pounds) of hazardous waste per month, and no more than 1 kilogram of acutely hazardous waste per month. Furthermore, a CESQG must not accumulate more than 1,000 kilograms (approximately 2,200 pounds) of hazardous waste at any given time. If a facility exceeds the CESQG thresholds for either monthly generation or on-site accumulation, it must then be classified as an SQG or LQG, depending on the quantities generated. An SQG generates between 100 and 1,000 kilograms of hazardous waste per month, while an LQG generates over 1,000 kilograms per month. The scenario describes a facility in Hawaii that generates 120 kilograms of hazardous waste in a month. This amount exceeds the 100-kilogram threshold for CESQG status. Since the generation is between 100 and 1,000 kilograms, the facility qualifies as a small quantity generator under HAR Chapter 11-260. The key determinant is the monthly generation rate, and the specific quantity of 120 kg clearly places it in the SQG category.

The Hawaii Revised Statutes (HRS) Chapter 342J, known as the “Hazardous Waste Management Act,” establishes the framework for managing hazardous waste within the state. This chapter, along with its corresponding administrative rules found in the Hawaii Administrative Rules (HAR) Chapter 11-261, delineates the responsibilities of generators, transporters, and treatment, storage, and disposal facilities (TSDFs). A key aspect of this regulatory scheme is the requirement for generators to properly identify and classify their hazardous waste. This classification process involves determining if a waste exhibits hazardous characteristics (ignitability, corrosivity, reactivity, toxicity) or if it is a listed hazardous waste. For wastes that are not explicitly listed, generators must conduct testing or use process knowledge to ascertain if the waste meets any of the characteristic criteria. The regulations in HAR Chapter 11-261, Subchapter 3, detail the specific testing methods and criteria for each characteristic. For instance, toxicity is often determined using the Toxicity Characteristic Leaching Procedure (TCLP), which simulates leaching in a landfill. If a waste is determined to be hazardous, the generator must then comply with all applicable requirements, including obtaining an EPA identification number, manifesting shipments, and adhering to storage limitations. The question probes the understanding of a generator’s initial obligation in the hazardous waste management process under Hawaii law.

Hawaii Administrative Rules (HAR) Chapter 11-261, specifically sections pertaining to generator status and waste determination, mandates rigorous analysis for classifying waste. A generator must determine if their waste exhibits any of the characteristics of hazardous waste: ignitability, corrosivity, reactivity, or toxicity. If the waste does not exhibit these characteristics, it is considered non-hazardous. The toxicity characteristic is determined by the Toxicity Characteristic Leaching Procedure (TCLP), outlined in HAR section 11-261-03(a)(1)(D). This procedure simulates landfill conditions to assess whether specific contaminants will leach into groundwater. If the concentration of any of the 40 regulated contaminants, when leached using TCLP, exceeds the regulatory levels specified in HAR section 11-261-03(a)(1)(D) Table I, the waste is classified as hazardous due to toxicity. For example, if a waste sample, when subjected to the TCLP, yields a leachate concentration of lead at 8 mg/L, and the regulatory limit for lead under the toxicity characteristic is 5 mg/L, then this waste would be classified as hazardous. The absence of any TCLP-exceeding contaminants, or the absence of the listed characteristics, leads to a non-hazardous classification. The question hinges on the correct interpretation of the TCLP results in relation to the established regulatory thresholds for toxicity characteristic contaminants as defined within Hawaii’s hazardous waste regulations.

The Hawaii Administrative Rules (HAR) Chapter 11-260.1, specifically concerning hazardous waste management, outlines stringent requirements for generators. A critical aspect of these regulations is the proper identification and management of hazardous waste. When a generator produces a waste that is not explicitly listed as hazardous under HAR 11-260.1, they must determine if it exhibits any hazardous characteristics. These characteristics are ignitability, corrosivity, reactivity, and toxicity. For toxicity, HAR 11-260.1, Section 11-260.1-4, references the Toxicity Characteristic Leaching Procedure (TCLP) as the standard method for determining if a waste is hazardous due to toxicity. If the TCLP analysis for any of the specified contaminants exceeds the regulatory limits, the waste is classified as hazardous. In this scenario, the waste from the electroplating process, when subjected to the TCLP for lead, yielded a concentration of 8.5 mg/L. The regulatory limit for lead under the Toxicity Characteristic (D008) in Hawaii, mirroring federal regulations under 40 CFR §261.24, is 5.0 mg/L. Since 8.5 mg/L is greater than 5.0 mg/L, the waste is definitively classified as a hazardous waste due to toxicity. Consequently, the generator must comply with all applicable hazardous waste generator requirements under HAR Chapter 11-260.1, including obtaining an EPA identification number, proper storage, manifesting for transport, and ensuring disposal at a permitted treatment, storage, and disposal facility.

The Hawaii Administrative Rules (HAR) Chapter 11-261, specifically concerning the identification and listing of hazardous waste, defines criteria for classifying waste. For waste generated from manufacturing processes, such as the production of photovoltaic cells, the characteristic of reactivity is crucial. Reactivity is defined by specific properties, including the tendency to explode or react violently with water, or to generate toxic gases when mixed with water or under other conditions. In Hawaii, a waste is considered reactive if it is a cyanide or sulfide bearing waste which, when exposed to pH conditions between 2 and 12.5, can generate toxic gases, vapors or fumes in a quantity sufficient to present a danger to human health or the environment. Alternatively, a waste is reactive if it is capable of detonation or explosive reaction under the pressure of a 1.0 kg drop hammer falling from a height of 1.0 meter. Another criterion is if it is a forbidden explosive. Considering the scenario of a facility generating waste from photovoltaic cell manufacturing, if process byproducts include materials that, when mixed with water, release flammable gases in quantities sufficient to cause a fire, or if they can detonate when subjected to a shock or friction test, they would be classified as reactive hazardous waste under Hawaii’s regulatory framework. This classification dictates specific management, storage, and disposal requirements to mitigate the inherent risks. The question probes the understanding of these specific reactivity criteria as applied to an industrial context in Hawaii, distinguishing it from general hazardous waste principles.

The Hawaii Administrative Rules (HAR) Chapter 11-260, specifically regarding hazardous waste management, defines the scope and applicability of hazardous waste regulations within the state. This chapter aligns with federal Resource Conservation and Recovery Act (RCRA) regulations but also includes Hawaii-specific provisions. When a facility generates hazardous waste, it must determine if it qualifies as a small quantity generator (SQG) or a large quantity generator (LQG) based on the amount of hazardous waste generated per month. These classifications dictate the specific management standards, storage limitations, and reporting requirements. For instance, an LQG generates 1,000 kilograms or more of hazardous waste per month, or more than 1 kilogram of acute hazardous waste. An SQG generates between 100 and 1,000 kilograms of hazardous waste per month. Generators are responsible for identifying their hazardous waste, obtaining an EPA identification number, managing waste in compliance with accumulation time limits, using proper containers and labeling, and ensuring transportation by licensed hazardous waste transporters to permitted treatment, storage, or disposal facilities. The exemption for generators of less than 100 kilograms per month of hazardous waste (excluding acute hazardous waste) is a key differentiator in regulatory burden, allowing very small generators to manage their waste with fewer stringent requirements, provided they meet specific criteria. This exemption is crucial for understanding the tiered approach to hazardous waste regulation in Hawaii, mirroring federal distinctions but applied within the unique context of the islands.

The Hawaii Administrative Rules (HAR) Chapter 11-260, specifically section 11-260-10, outlines the requirements for hazardous waste generator identification. A facility is considered a hazardous waste generator if it produces hazardous waste. The regulations define different generator categories based on the quantity of hazardous waste produced per month. A very small quantity generator (VSQG) is defined as a facility that produces no more than 100 kilograms (approximately 220 pounds) of hazardous waste per month, or no more than 1 kilogram of acutely hazardous waste per month. A small quantity generator (SQG) produces more than 100 kilograms but less than 1,000 kilograms of hazardous waste per month. A large quantity generator (LQG) produces 1,000 kilograms or more of hazardous waste per month, or more than 1 kilogram of acutely hazardous waste per month. In this scenario, the facility consistently generates 150 kilograms of hazardous waste per month. This quantity exceeds the 100-kilogram threshold for a VSQG and falls within the range for a small quantity generator. Therefore, the facility must comply with the regulations applicable to small quantity generators, which include requirements for manifest tracking, storage time limits, and personnel training, among others, as stipulated in HAR Chapter 11-260. The determination of generator status is crucial for ensuring proper management and disposal of hazardous waste, thereby protecting public health and the environment in Hawaii.
