The Illinois Environmental Protection Agency (IEPA) is responsible for implementing and enforcing the state’s hazardous waste regulations, which are primarily found in the Illinois Environmental Protection Act and the Illinois Administrative Code, specifically Title 35, Subtitle G. Generators of hazardous waste in Illinois are subject to stringent requirements for waste identification, management, and record-keeping. The Illinois EPA’s regulations mirror many of the federal requirements under the Resource Conservation and Recovery Act (RCRA), but can also include additional state-specific provisions. For a generator to be considered a “small quantity generator” (SQG) in Illinois, they must meet specific criteria regarding the amount of hazardous waste generated per month and the amount stored on-site at any given time. Under Illinois regulations, an SQG is a generator who generates less than 1,000 kilograms (approximately 2,200 pounds) of hazardous waste in a calendar month and accumulates less than 6,000 kilograms (approximately 13,200 pounds) of hazardous waste on-site at any one time. Furthermore, an SQG cannot accumulate hazardous waste on-site for more than 180 days without a permit, or 270 days if the waste must be transported over 200 miles. These distinctions in generator status are crucial as they dictate the specific management, reporting, and emergency preparedness requirements that must be followed. Failure to correctly classify and manage hazardous waste according to these thresholds can lead to significant penalties.

The Illinois Environmental Protection Agency (IEPA) has established specific requirements for the management of hazardous waste. When a generator discovers that they have significantly exceeded their hazardous waste generator status, they must take immediate action. The Illinois Administrative Code, specifically 35 Ill. Adm. Code Part 722, outlines these obligations. A key provision within this regulation mandates that a generator who has exceeded their previously determined hazardous waste generator status must notify the IEPA within three days of the discovery. This notification is crucial for ensuring that the generator is operating under the correct regulatory framework and is in compliance with the applicable management standards. The purpose of this rapid notification is to prevent potential environmental harm by quickly bringing the generator’s activities into alignment with the more stringent requirements that apply to higher generator categories. This is a fundamental aspect of the cradle-to-grave responsibility inherent in hazardous waste management.

The Illinois Environmental Protection Agency (IEPA) employs specific criteria to identify hazardous waste. A waste is considered hazardous if it is listed by the agency or if it exhibits certain characteristics. The characteristic of ignitability, as defined in 35 Illinois Administrative Code (IAC) Part 721, includes liquids with a flash point below 60 degrees Celsius (140 degrees Fahrenheit). It also includes non-liquids capable of causing fire through spontaneous chemical changes or friction, and ignitable compressed gases. Oxidizers are also included. The scenario describes a waste material that is a liquid with a flash point of 55 degrees Celsius. This value is below the threshold of 60 degrees Celsius, thus meeting the characteristic of ignitability under Illinois hazardous waste regulations. Therefore, this waste would be classified as hazardous. The other options present scenarios that do not inherently meet the defined characteristics of hazardous waste under 35 IAC Part 721. A waste exhibiting corrosivity would typically have a pH of less than or equal to 2 or greater than or equal to 12.5, or be a liquid that corrodes steel at a rate greater than 6.35 mm per year. Reactivity refers to wastes that are unstable, react violently with water, or generate toxic gases. Toxicity is determined through the Toxicity Characteristic Leaching Procedure (TCLP).

The Illinois Environmental Protection Agency (IEPA) establishes specific requirements for the management of hazardous waste. Under the Illinois Administrative Code, specifically 35 Ill. Adm. Code Part 722, generators of hazardous waste are subject to various obligations. One crucial aspect is the proper classification and record-keeping for waste generated. If a facility in Illinois generates a waste stream that exhibits characteristics of hazardous waste, such as ignitability, corrosivity, reactivity, or toxicity, it must be managed according to the stringent regulations. For instance, if a waste stream fails the Toxicity Characteristic Leaching Procedure (TCLP) for a specific constituent listed in 35 Ill. Adm. Code Part 721, Appendix H, it is classified as hazardous. The generator is then responsible for obtaining an EPA identification number, manifesting the waste for off-site shipment to a permitted treatment, storage, or disposal facility (TSDF), and maintaining records of these shipments. The record-keeping requirement typically includes copies of manifests, test results, and biennial reports, which must be kept for a minimum of three years from the date the waste was last sent to an off-site TSDF. This period ensures that the IEPA can conduct audits and verify compliance with waste management protocols. Therefore, a generator in Illinois must retain records of hazardous waste shipments for at least three years following the last shipment of that particular waste stream.

The Illinois Environmental Protection Agency (IEPA) has established specific requirements for the management of hazardous waste. Under the Illinois Environmental Protection Act and its associated administrative rules, generators of hazardous waste are responsible for determining if their waste is hazardous. This determination is crucial for proper storage, transportation, and disposal. The regulations outline a process that involves checking against listed hazardous wastes and evaluating for characteristic hazardous waste properties, such as ignitability, corrosivity, reactivity, and toxicity. If a waste exhibits any of these characteristics, or if it is specifically listed by the IEPA or the U.S. Environmental Protection Agency (USEPA) as hazardous, it must be managed accordingly. This includes obtaining an EPA identification number, adhering to manifest requirements for off-site shipments, and complying with storage time limits and container management standards. The concept of “cradle-to-grave” responsibility means the generator remains liable for the waste from its generation until its final disposition. For waste exhibiting the characteristic of toxicity, the Toxicity Characteristic Leaching Procedure (TCLP) is a key analytical method used to determine if specific contaminants will leach from the waste at concentrations exceeding regulatory thresholds. Failure to correctly classify and manage hazardous waste can result in significant penalties. Therefore, a thorough understanding of the waste determination process, including the application of characteristic tests like TCLP, is fundamental for compliance in Illinois.

The Illinois Environmental Protection Agency (IEPA) designates specific waste streams as hazardous under the Illinois Environmental Protection Act, often aligning with federal Resource Conservation and Recovery Act (RCRA) definitions. When a facility generates a waste that exhibits a characteristic of hazardous waste (ignitability, corrosivity, reactivity, or toxicity) or is listed as a hazardous waste, it becomes subject to Illinois hazardous waste regulations. For a generator to be exempt from certain stringent management standards, such as those for Treatment, Storage, and Disposal Facilities (TSDFs), they must comply with generator-specific requirements, including proper identification, accumulation time limits, manifesting, and record-keeping. A key aspect of compliance for small quantity generators (SQGs) in Illinois is managing hazardous waste in containers that are in good condition, compatible with the waste, and kept closed. The accumulation time limit for SQGs is typically 180 days, with provisions for an extension to 270 days if the waste must be transported over 200 miles. During this accumulation period, the containers must be clearly marked with the words “Hazardous Waste” and the accumulation start date. The regulatory framework in Illinois, primarily through 35 Illinois Administrative Code Subtitle G, Chapter I, mandates these practices to prevent environmental contamination and ensure safe handling. Failure to meet these requirements can result in enforcement actions by the IEPA.

The Illinois Environmental Protection Agency (IEPA) has established specific requirements for the management of hazardous waste. When a generator produces hazardous waste, they must comply with various regulations to ensure proper handling, storage, and disposal. One critical aspect is determining the generator status, which dictates the stringency of applicable rules. For a small quantity generator in Illinois, the threshold for hazardous waste generation is between 100 and 1,000 kilograms of hazardous waste per calendar month, or less than 1 kilogram of acutely hazardous waste per calendar month. Furthermore, a small quantity generator cannot accumulate more than 6,000 kilograms of hazardous waste on-site at any given time. The accumulation period for hazardous waste generated by a small quantity generator is limited to 180 days, unless a variance is granted for transport to a treatment, storage, or disposal facility located more than 200 miles away, in which case the accumulation period can be extended to 270 days. This accumulation limit is a crucial compliance point. If a generator exceeds either the monthly generation threshold or the on-site accumulation quantity, they are reclassified as a large quantity generator and must comply with the more stringent regulations applicable to that category. The specific waste codes and characteristics, as defined by the Illinois Administrative Code, are also paramount in this determination.

The Illinois Environmental Protection Agency (IEPA) employs a tiered approach to classifying waste. Under the Illinois Environmental Protection Act and its associated administrative rules, specifically 35 Illinois Administrative Code Subtitle G, waste is initially assessed for its hazardous characteristics. If a waste exhibits any of the defined characteristics of hazardous waste (ignitability, corrosivity, reactivity, or toxicity), it is classified as hazardous. For waste not exhibiting these characteristics, further evaluation is necessary. The Act and regulations also define “pollution control waste” and “special waste.” Pollution control waste, often generated from pollution control processes, may be exempt from certain regulations if it meets specific criteria and is managed appropriately. Special waste, a broader category, includes waste that is not hazardous but may still pose a threat to public health or the environment. The determination of whether a waste is a “pollution control waste” or a “special waste” hinges on its origin and composition, and whether it meets the statutory definitions and any applicable exemptions. A waste stream generated from a scrubber system designed to remove sulfur dioxide from flue gas, if properly characterized and managed, could potentially be classified as pollution control waste, which may have different management requirements than other special wastes. The key is the specific exemption criteria outlined in the Illinois regulations, which often relate to the source and the absence of hazardous characteristics.

The Illinois Environmental Protection Agency (IEPA) has specific regulations regarding the management of hazardous waste, particularly concerning the definition of a hazardous waste generator and their responsibilities. Under the Illinois Administrative Code, Title 35, Subtitle G, Part 700, the classification of a generator is based on the quantity of hazardous waste produced per calendar month. A very small quantity generator (VSQG) is defined as a generator who generates less than 100 kilograms (approximately 220 pounds) of hazardous waste per calendar month. A small quantity generator (SQG) generates between 100 kilograms and 1,000 kilograms (approximately 2,200 pounds) of hazardous waste per calendar month. A large quantity generator (LQG) generates 1,000 kilograms or more of hazardous waste per calendar month. The question presents a scenario where a facility generates 110 kilograms of hazardous waste in January and 90 kilograms in February. To determine the generator status for February, we consider the monthly generation rate. Since the facility generated 90 kilograms in February, which is less than 100 kilograms, it falls under the Very Small Quantity Generator (VSQG) category for that month. This classification dictates specific, less stringent management and reporting requirements compared to SQGs or LQGs, as outlined in the Illinois regulations. Understanding these thresholds is crucial for compliance.

The Illinois Environmental Protection Agency (IEPA) establishes specific requirements for the management of hazardous waste. Under the Illinois Environmental Protection Act and its corresponding administrative rules, particularly 35 Illinois Administrative Code Subtitle G, generators of hazardous waste are obligated to determine if their waste is hazardous. This determination is a critical first step. If a waste exhibits a characteristic of hazardous waste (ignitability, corrosivity, reactivity, or toxicity) or is listed as hazardous by the IEPA, it must be managed accordingly. The generator is responsible for correctly classifying the waste and adhering to all applicable regulations for storage, transportation, and disposal. Failure to properly classify a waste can lead to significant penalties. The specific threshold for toxicity characteristic leaching procedure (TCLP) for certain metals, like lead, is 5.0 mg/L, as defined by federal RCRA regulations which Illinois largely adopts. However, the question asks about the initial determination of hazardousness based on characteristic properties, not a specific disposal threshold. The generator’s responsibility to make this initial determination is a foundational requirement for all hazardous waste management.

The Illinois Environmental Protection Agency (IEPA) regulates hazardous waste management under the Illinois Environmental Protection Act and the Illinois Administrative Code, specifically Title 35, Subtitle G. A key aspect of this regulation involves the identification and management of hazardous waste. When a generator produces a waste that is not specifically listed as hazardous (e.g., F, K, P, or U lists), they must determine if it exhibits any of the hazardous characteristics defined in 35 Ill. Adm. Code Part 721. These characteristics are ignitability, corrosivity, reactivity, and toxicity. The toxicity characteristic is determined by the Toxicity Characteristic Leaching Procedure (TCLP), as outlined in 35 Ill. Adm. Code Part 721, Subpart C. If a waste fails the TCLP for any of the regulated constituents, it is classified as a hazardous waste. For example, if a waste, when subjected to the TCLP, leaches more than 5.0 mg/L of lead, it is considered hazardous due to toxicity. The generator must then comply with all applicable hazardous waste management requirements, including obtaining an EPA identification number, proper storage, labeling, manifesting for transportation, and disposal at a permitted treatment, storage, or disposal facility (TSDF). The regulatory framework in Illinois mirrors the federal Resource Conservation and Recovery Act (RCRA) but may include state-specific nuances or additional requirements. The core principle is that any waste exhibiting a hazardous characteristic or listed as hazardous must be managed according to strict protocols to protect human health and the environment in Illinois.

The Illinois Environmental Protection Agency (IEPA) is responsible for implementing and enforcing the Illinois Environmental Protection Act and its associated regulations, including those pertaining to hazardous waste management. Under the Resource Conservation and Recovery Act (RCRA) framework, which Illinois largely mirrors, facilities that generate, treat, store, or dispose of hazardous waste are subject to specific permitting and operational requirements. The term “generator” is defined based on the quantity of hazardous waste produced per month. For large quantity generators (LQGs), this threshold is typically 1,000 kilograms or more of hazardous waste, or 1 kilogram or more of acute hazardous waste, per calendar month. Small quantity generators (SQGs) fall within a lower range, generally between 100 and 1,000 kilograms of hazardous waste per month, with specific conditions. Very small quantity generators (VSQGs) generate even less. The question asks about the primary regulatory body responsible for overseeing hazardous waste management in Illinois. This oversight involves developing regulations, issuing permits, conducting inspections, and enforcing compliance with federal and state laws. The Illinois Environmental Protection Agency (IEPA) is the designated state agency tasked with these crucial functions, ensuring that hazardous waste is managed in a manner that protects public health and the environment throughout the state of Illinois. Other entities, such as the Illinois Department of Natural Resources (IDNR) or the Illinois Pollution Control Board (IPCB), have related but distinct roles. The IDNR manages natural resources and state parks, while the IPCB is the primary adjudicatory body for environmental regulations and rulemaking. The U.S. Environmental Protection Agency (USEPA) has ultimate federal authority but delegates primary implementation and enforcement to authorized states like Illinois.

The Illinois Environmental Protection Agency (IEPA) has specific regulations regarding the management of hazardous waste, particularly concerning the classification and handling of waste streams that may exhibit characteristics of hazardous waste. Under the Illinois Environmental Protection Act and its associated administrative rules, specifically 35 Ill. Adm. Code Part 721, generators are responsible for determining if their waste is hazardous. This determination involves either knowledge of the waste’s composition and origin or by testing. If a waste exhibits any of the four characteristics of hazardous waste – ignitability, corrosivity, reactivity, or toxicity – it is classified as hazardous. The toxicity characteristic is determined by the Toxicity Characteristic Leaching Procedure (TCLP), outlined in 35 Ill. Adm. Code Part 721, Appendix B. If the leachate from a TCLP test for a specific constituent exceeds the regulatory threshold, the waste is deemed hazardous for that characteristic. For example, if a waste material, when subjected to the TCLP, yields a leachate concentration of lead exceeding 5.0 mg/L, it is classified as hazardous waste due to toxicity characteristic for lead. This classification triggers stringent management requirements, including proper labeling, storage, transportation by licensed haulers, and disposal at permitted treatment, storage, and disposal facilities (TSDFs). Generators must maintain records of their hazardous waste determinations. The regulatory framework aims to protect human health and the environment from the adverse effects of hazardous waste.

The Illinois Environmental Protection Agency (IEPA) employs a tiered approach to hazardous waste management, aligning with federal Resource Conservation and Recovery Act (RCRA) regulations, but with specific Illinois interpretations and additions. Under Illinois law, a generator of hazardous waste is responsible for determining if their waste is hazardous. This determination is crucial for subsequent management requirements, including storage, transportation, and disposal. The process involves consulting the Illinois Administrative Code (35 Ill. Adm. Code Part 721), which lists hazardous wastes and defines characteristics of hazardous waste. Characteristic wastes are those that exhibit ignitability, corrosivity, reactivity, or toxicity. If a waste meets any of these characteristic definitions or is specifically listed as hazardous in the regulations, it is subject to stringent hazardous waste management rules. The generator’s duty to know their waste is a fundamental principle, meaning they must actively investigate the properties of the waste they produce. This proactive assessment dictates the entire lifecycle management of the hazardous material. Failure to correctly identify and manage hazardous waste can result in significant penalties and liabilities. Therefore, a thorough understanding of the characteristic criteria and listed waste categories within the Illinois regulatory framework is paramount for any entity generating such materials.

The Illinois Environmental Protection Agency (IEPA) designates specific hazardous waste treatment, storage, and disposal facilities (TSDFs) as needing permits under the Resource Conservation and Recovery Act (RCRA), as implemented by Illinois law. Facilities that store hazardous waste for more than 90 days are generally required to obtain a RCRA permit. However, certain exemptions exist. A generator who stores hazardous waste on-site for 90 days or less, and who meets specific accumulation quantity limits and operational requirements, may be exempt from obtaining a TSDF permit for that storage. For small quantity generators (SQGs) in Illinois, the accumulation limit is typically 6,000 kilograms of hazardous waste. If a generator accumulates more than this amount, or stores it for longer than 180 days (or 270 days if the waste is being transported to a permitted TSDF over 200 miles away), they generally lose the exemption and must obtain a RCRA permit. The scenario describes a facility generating hazardous waste and storing it for 120 days. To determine if a permit is required, we compare the storage duration to the exemption period. Since 120 days exceeds the 90-day general exemption for generators, and assuming the quantity limits for a generator (which are not specified but are a prerequisite for any generator exemption) are met, the facility would likely need a permit for this extended storage. The question focuses on the *need for a permit for storage beyond the typical generator exemption period*. The key is the duration of storage. If a facility is not a generator operating under an exemption, but rather a facility that *only* stores waste, then a permit is almost certainly required regardless of quantity or duration, as storage is a regulated activity. However, the question implies a generator scenario. The 90-day limit is a critical threshold for generator-based exemptions. Exceeding this limit for storage without a permit typically triggers the requirement for one.

The Illinois Environmental Protection Agency (IEPA) has specific requirements for the management of hazardous waste. Under the Illinois Environmental Protection Act and its associated administrative rules, particularly those mirroring the federal Resource Conservation and Recovery Act (RCRA), generators of hazardous waste must adhere to stringent standards. When a generator determines that a waste exhibits a characteristic of hazardous waste, such as ignitability, corrosivity, reactivity, or toxicity, they must assign a hazardous waste code. For waste that is hazardous due to its toxicity characteristic, Illinois regulations specify codes that reflect the specific constituent causing the toxicity, often linked to the Toxicity Characteristic Leaching Procedure (TCLP) results. If a waste is a characteristic hazardous waste but not specifically listed, it receives a “D” code. In this scenario, the waste exhibits ignitability and corrosivity. Ignitability is typically coded as D001, and corrosivity is coded as D002. Therefore, a waste exhibiting both characteristics would require both applicable codes. The question asks for the correct coding for a waste that is ignitable and corrosive. The Illinois regulations, consistent with federal RCRA, assign D001 for ignitability and D002 for corrosivity. Thus, the waste must be managed as both ignitable and corrosive, requiring both codes.

The Illinois Environmental Protection Agency (IEPA) employs a tiered approach to classifying waste based on its potential to cause harm. Under the Illinois Environmental Protection Act and its associated administrative rules, specifically the Illinois Administrative Code Title 35, Subtitle G, Chapter I, Part 721, waste materials are categorized. A waste is considered hazardous if it exhibits one or more of the characteristics of hazardous waste: ignitability, corrosivity, reactivity, or toxicity. Alternatively, a waste is hazardous if it is listed by the IEPA as a hazardous waste. The toxicity characteristic is determined by the Toxicity Characteristic Leaching Procedure (TCLP), which simulates leaching in a landfill. If the leachate from a waste sample contains any of the specified contaminants at concentrations equal to or exceeding the regulatory thresholds, the waste is classified as toxic hazardous waste. For example, if a waste exhibits a pH less than 2.0, it is classified as corrosive hazardous waste. If a waste is generated from a specific process listed as generating hazardous waste, it is also classified as hazardous. The question asks to identify the primary regulatory framework in Illinois that governs the identification and classification of hazardous waste. This framework is primarily established by the Illinois Environmental Protection Act and further detailed through the IEPA’s administrative rules, particularly those mirroring federal RCRA regulations. Therefore, the identification and classification of hazardous waste in Illinois are directly tied to the specific definitions and criteria set forth in these state statutes and rules, which align with but are not identical to federal definitions.

The Illinois Environmental Protection Agency (IEPA) oversees the state’s hazardous waste management program, which is largely based on the federal Resource Conservation and Recovery Act (RCRA). Under Illinois law, specifically the Environmental Protection Act and the Illinois Administrative Code (35 Ill. Adm. Code Subtitle G), facilities that treat, store, or dispose of hazardous waste must obtain a permit. The permitting process involves a thorough review of the facility’s design, operation, and environmental impact. A key aspect of this is demonstrating compliance with stringent technical standards and financial assurance requirements. Financial assurance ensures that funds are available to properly close the facility and manage any post-closure care needed to protect human health and the environment, even if the facility becomes insolvent. This requirement is critical for preventing orphan sites and ensuring long-term environmental protection. The specific mechanisms for financial assurance can include trust funds, surety bonds, letters of credit, or corporate guarantees, among others, as detailed in the regulations. The purpose is to guarantee that the responsible party has the financial capacity to meet their obligations, regardless of future financial circumstances. This is a fundamental principle of hazardous waste regulation to safeguard public health and the environment in Illinois.

The Illinois Environmental Protection Agency (IEPA) is responsible for administering and enforcing the state’s hazardous waste regulations, which are largely based on the federal Resource Conservation and Recovery Act (RCRA) but may include stricter or additional requirements. Under Illinois law, specifically the Illinois Environmental Protection Act and its associated administrative rules (such as 35 Ill. Adm. Code Subtitle G), generators of hazardous waste are subject to specific management standards. These standards dictate how hazardous waste must be stored, treated, and transported. For a generator to be classified as a “small quantity generator” (SQG) in Illinois, they must meet certain criteria regarding the amount of hazardous waste produced per month and the accumulation limits for hazardous waste on-site. The threshold for SQGs in Illinois is generally producing between 100 and 1,000 kilograms of hazardous waste per month, and accumulating no more than 6,000 kilograms of hazardous waste on-site at any given time. If a generator exceeds either of these monthly production or accumulation limits, they are reclassified as a large quantity generator (LQG) and must comply with the more stringent LQG regulations. The question asks about the generator status when a facility produces 1,100 kilograms of hazardous waste in a month. This amount exceeds the 1,000-kilogram threshold for SQGs. Therefore, the facility would be classified as a large quantity generator for that month, necessitating adherence to LQG management standards, including potentially shorter accumulation time limits and more rigorous manifest requirements, among other obligations.

The Illinois Environmental Protection Agency (IEPA) categorizes hazardous waste generators based on the quantity of hazardous waste produced per month. The Illinois definition of a “small quantity generator” (SQG) is a facility that generates at least 100 kilograms but less than 1,000 kilograms of hazardous waste in a calendar month, or less than 1 kilogram of acute hazardous waste in a calendar month. A “large quantity generator” (LQG) is a facility that generates 1,000 kilograms or more of hazardous waste per month, or more than 1 kilogram of acute hazardous waste per month. An “excepted quantity generator” (EQG) is a facility that generates 100 kilograms or less of hazardous waste per month, and less than 1 kilogram of acute hazardous waste per month. In this scenario, the facility generates 950 kilograms of non-acute hazardous waste and 0.5 kilograms of acute hazardous waste in a calendar month. Since the non-acute hazardous waste generation (950 kg) is between 100 kg and 1,000 kg, and the acute hazardous waste generation (0.5 kg) is less than 1 kg, the facility meets the criteria for a small quantity generator under Illinois regulations. This classification dictates specific management, record-keeping, and reporting requirements under the Illinois Environmental Protection Act and its associated administrative rules. Understanding these thresholds is crucial for compliance and proper hazardous waste management within Illinois.

The Illinois Environmental Protection Agency (IEPA) is responsible for administering and enforcing the Illinois Environmental Protection Act, which includes regulations governing hazardous waste management. Under this act, specifically referencing 415 ILCS 5/22.2, generators of hazardous waste are subject to specific requirements. The question pertains to the conditions under which a generator in Illinois might be exempt from certain manifest requirements. The Illinois Administrative Code, specifically 35 Ill. Adm. Code Part 722, outlines these generator requirements. Part 722.110 details the requirements for generators of hazardous waste. A key exemption from the manifest system for on-site generated hazardous waste is provided when the waste is treated, stored, or disposed of at the same facility where it was generated, provided that the facility is permitted to manage that hazardous waste under the Act. This exemption is designed to streamline management for closed-loop systems or internal processes where the waste never leaves the generator’s site and is handled under existing facility permits. The exemption is not based on the quantity of waste generated, the type of hazardous waste, or the fact that it is shipped off-site to a permitted facility, as these scenarios typically require a manifest. The core condition for exemption from manifest requirements for on-site generated waste is the absence of off-site transportation and the management of the waste at the same permitted facility.

The Illinois Environmental Protection Agency (IEPA) regulates hazardous waste management under the Illinois Environmental Protection Act and the Resource Conservation and Recovery Act (RCRA) as implemented in Illinois. 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 its monthly generation rates. For SQGs, the limit is between 100 kilograms (kg) and 1,000 kg of hazardous waste per month, or less than 1 kg of acute hazardous waste per month. LQGs generate 1,000 kg or more of hazardous waste per month, or more than 1 kg of acute hazardous waste per month. A conditionally exempt small quantity generator (CESQG) generates 100 kg or less of non-acute hazardous waste per month, and less than 1 kg of acute hazardous waste per month. In this scenario, the facility generates 850 kg of hazardous waste in January and 1,100 kg in February. The classification as an SQG or LQG is determined by the highest amount generated in any single month. Since 1,100 kg is greater than 1,000 kg, the facility would be classified as a large quantity generator for both months, as the LQG threshold was met in February. This classification dictates specific requirements for storage, record-keeping, reporting, and personnel training, as outlined in the Illinois Administrative Code, Title 35, Subtitle G. Therefore, the facility’s status for the period encompassing January and February would be that of a large quantity generator due to exceeding the 1,000 kg threshold in February.

The Illinois Environmental Protection Agency (IEPA) mandates specific requirements for the management of hazardous waste. When a generator of hazardous waste in Illinois discovers that they have significantly exceeded the quantity limits for their generator status, they must immediately take steps to reclassify their status. This involves notifying the IEPA and complying with the requirements of the new, higher generator category. The Illinois Administrative Code, specifically 35 Ill. Adm. Code Part 700 and related parts concerning generator requirements, outlines these obligations. Failure to promptly reclassify can result in enforcement actions and penalties. The prompt reclassification demonstrates responsible waste management and adherence to regulatory frameworks designed to protect public health and the environment in Illinois. This proactive approach is crucial for maintaining compliance and preventing potential liabilities associated with improper hazardous waste management. The core principle is that a generator’s responsibilities are directly tied to the volume of hazardous waste they produce, and any substantial increase necessitates an immediate adjustment in their operational and reporting procedures to align with the applicable regulatory standards.

The Illinois Environmental Protection Agency (IEPA) has established specific requirements for the management of hazardous waste. Under the Illinois Environmental Protection Act and associated regulations, facilities that generate, treat, store, or dispose of hazardous waste are subject to permitting and operational standards. A key aspect of these regulations pertains to the management of waste that exhibits certain hazardous characteristics, such as ignitability, corrosivity, reactivity, or toxicity. For waste to be classified as hazardous in Illinois, it must meet the criteria defined in the Illinois Administrative Code, specifically 35 Ill. Adm. Code Part 721. This part details the identification and listing of hazardous wastes, including those that are characteristically hazardous. The scenario describes a facility generating a waste stream that, upon testing, exhibits a pH of 1.5. This pH value indicates a highly acidic characteristic. According to 35 Ill. Adm. Code Part 721, Subpart C, a waste is considered corrosive if it is aqueous and has a pH less than or equal to 2 or greater than or equal to 12.5, or if it is a liquid and corrodes steel (SAE 1020) at a rate greater than 6.35 mm per year. Since the waste has a pH of 1.5, it clearly meets the criteria for being a characteristically hazardous waste due to corrosivity. Therefore, the facility must manage this waste in accordance with all applicable Illinois hazardous waste regulations, including those related to storage, transportation, and disposal, as if it were a listed hazardous waste. This necessitates proper containerization, labeling, record-keeping, and manifesting for all shipments.

The Illinois Environmental Protection Agency (IEPA) oversees the management of hazardous waste within the state. Under the Illinois Environmental Protection Act and its corresponding administrative rules, specifically 35 Illinois Administrative Code (IAC) Subtitle G, facilities that generate, treat, store, or dispose of hazardous waste are subject to stringent requirements. A key aspect of these regulations involves the identification and classification of hazardous waste. Waste is deemed hazardous if it is listed by the IEPA or if it exhibits a characteristic of hazardous waste, such as ignitability, corrosivity, reactivity, or toxicity. The toxicity characteristic is determined through specific testing protocols, such as the Toxicity Characteristic Leaching Procedure (TCLP). If a waste fails TCLP for any of the regulated constituents, it is classified as hazardous. The scenario presented involves a solvent mixture that, when subjected to the TCLP for a specific constituent, exhibits a concentration exceeding the regulatory limit. This outcome mandates its classification as hazardous waste. Therefore, the facility must manage this waste according to the full suite of hazardous waste regulations in Illinois, including manifesting, proper storage, transportation by licensed haulers, and disposal at a permitted treatment, storage, and disposal facility (TSDF). Failure to comply can result in significant penalties. The concept being tested is the application of characteristic hazardous waste identification criteria in Illinois.

The Illinois Environmental Protection Agency (IEPA) designates specific waste streams as hazardous based on characteristics like ignitability, corrosivity, reactivity, or toxicity, or if they are listed by the agency. The Illinois Administrative Code, specifically 35 Ill. Adm. Code Part 721, outlines the criteria and lists for hazardous waste identification. A generator is responsible for determining if their waste is hazardous. This determination involves reviewing the waste against the characteristic criteria and the listed wastes. If a waste exhibits any of the hazardous characteristics or is specifically listed as hazardous, it is subject to the regulations under the Illinois Environmental Protection Act and its associated rules, which align closely with the federal Resource Conservation and Recovery Act (RCRA). The generator must then manage the waste according to the applicable hazardous waste management standards, including proper storage, labeling, manifesting, and disposal at a permitted facility. Failure to correctly identify and manage hazardous waste can result in significant penalties and liabilities. The scenario describes a manufacturing process that produces a byproduct. The crucial step for the generator is to perform a hazardous waste determination on this byproduct. This determination is a fundamental responsibility of any entity generating waste that might be hazardous.

The Illinois Environmental Protection Agency (IEPA) is the primary regulatory body for hazardous waste management in Illinois. Under the Illinois Environmental Protection Act and its associated administrative rules, specifically the Illinois Administrative Code Title 35, Subtitle G, Chapter I, the IEPA oversees the permitting, operation, and closure of hazardous waste facilities. A critical aspect of this oversight involves the financial assurance requirements for closure and post-closure care. These requirements are designed to ensure that funds are available to properly manage a hazardous waste site even if the owner or operator becomes insolvent. The regulations specify various mechanisms for demonstrating financial assurance, such as trust funds, surety bonds, letters of credit, and insurance. The selection and establishment of these mechanisms are subject to IEPA approval, ensuring they meet the strict criteria for guaranteeing the availability of funds throughout the facility’s lifecycle. The concept of “owner or operator” is fundamental, as liability for proper waste management and financial assurance rests with those who own or control the hazardous waste facility. The IEPA’s role is to enforce these requirements through inspections, audits, and enforcement actions to protect human health and the environment in Illinois.

The Illinois Environmental Protection Agency (IEPA) utilizes a tiered approach for classifying waste based on its potential to cause harm. Under the Illinois Environmental Protection Act and its associated regulations, specifically the Illinois Administrative Code Title 35, Subtitle G, Chapter I, Part 721, waste is categorized as hazardous if it exhibits certain characteristics or is listed. The characteristic wastes are ignitability, corrosivity, reactivity, and toxicity. Toxicity is determined by the Toxicity Characteristic Leaching Procedure (TCLP). If a waste leaches specific contaminants above regulatory thresholds, it is classified as toxic hazardous waste. For the purpose of this question, we are considering a waste stream that has been tested and found to leach arsenic at a concentration of 6.5 mg/L. The regulatory limit for arsenic under the Toxicity Characteristic (TC) is 5.0 mg/L. Since 6.5 mg/L is greater than 5.0 mg/L, the waste exhibits the toxicity characteristic. Therefore, this waste is classified as a hazardous waste under Illinois law due to its toxicity. The specific regulatory citation for this characteristic is found within the Illinois regulations mirroring the federal Resource Conservation and Recovery Act (RCRA) regulations, specifically relating to the toxicity characteristic.

The Illinois Environmental Protection Agency (IEPA) is responsible for the oversight and enforcement of hazardous waste regulations within the state, primarily under the Illinois Environmental Protection Act and the Illinois Administrative Code, specifically Title 35, Subtitle G. Generators of hazardous waste are categorized based on the quantity of hazardous waste produced per calendar month. These categories determine the specific regulatory requirements they must adhere to, including storage limitations, record-keeping, and reporting. A small quantity generator (SQG) is defined as a generator who produces between 100 and 1,000 kilograms (approximately 220 to 2,200 pounds) of hazardous waste per calendar month. For SQGs, the maximum amount of hazardous waste that can be accumulated on-site at any one time is 6,000 kilograms. This accumulation limit is a critical compliance point. If an SQG exceeds this limit, they are reclassified as a large quantity generator (LQG) and must comply with the more stringent regulations applicable to LQGs, which include stricter time limits for accumulation and more extensive management standards. Therefore, managing waste generation and accumulation to stay within the SQG threshold of 6,000 kilograms is paramount for compliance for entities falling into this category in Illinois.

The Illinois Environmental Protection Agency (IEPA) utilizes a tiered approach for classifying waste as hazardous. This classification is primarily governed by the Illinois Administrative Code, specifically Title 35, Subtitle G, Part 721, which mirrors the federal Resource Conservation and Recovery Act (RCRA) regulations for identifying and listing hazardous wastes. A waste is deemed hazardous if it is specifically listed by the IEPA or if it exhibits one or more of the four characteristics of hazardous waste: ignitability, corrosivity, reactivity, or toxicity. The toxicity characteristic is determined by the Toxicity Characteristic Leaching Procedure (TCLP), outlined in 35 Ill. Adm. Code 721.124. This test simulates the leaching that occurs when waste is disposed of in a landfill. If the leachate from a waste sample contains any of the specified contaminants (e.g., heavy metals, certain organic compounds) at concentrations equal to or exceeding the regulatory thresholds, the waste is classified as hazardous due to toxicity. For instance, if a waste sample, when subjected to the TCLP, yields a leachate concentration of lead at 5.5 mg/L, and the regulatory limit for lead under the toxicity characteristic is 5.0 mg/L, then the waste is considered hazardous for toxicity. This determination dictates the subsequent management, treatment, storage, and disposal requirements under Illinois hazardous waste regulations. The fundamental principle is to prevent the release of harmful substances into the environment.
