#### Regulation .01 Purpose, Scope, and Applicability.

*COMAR 26.13.03.01*

A. These regulations establish standards for generators of hazardous waste, and include:

  (1) Requirements that must be met in order for a generator to qualify for exemptions from specified requirements of COMAR 26.13; and

  (2) Requirements that a generator must meet independently of those requirements that determine eligibility for a conditional exemption, with these independent requirements including:

    (a) Hazardous waste determination and record keeping requirements of Regulations .02, .02-1, and .02-2 of this chapter;

    (b) Determination of applicability of requirements of this chapter based on amounts of hazardous waste generated and amounts of hazardous waste accumulated, as specified in §§A-1 and A-2 of this regulation;

    (c) Requirements concerning EPA identification numbers and renotification in Regulations .03—.03-2 of this chapter;

    (d) Manifest requirements of Regulation .04 of this chapter;

    (e) Pre-transport requirements of Regulation .05 of this chapter;

    (f) Record keeping and reporting requirements of Regulation .06 of this chapter; and

    (g) Requirements of 40 CFR Part 262 Subpart H, concerning transboundary movements of hazardous waste for recovery and disposal.

A-1. To determine the applicability of a provision of this chapter that depends on the amount of hazardous waste generated per calendar month, a person shall use the criteria of COMAR 26.13.02.05A(2) and (3) in calculating the amount of hazardous waste generated.

A-2. Except as provided in §§J—L of this regulation, a person is subject to the requirements of this chapter if the person meets any of the following criteria:

  (1) Generates 100 kilograms or more of hazardous waste in a calendar month;

  (2) Accumulates, at any time, more than 100 kilograms of hazardous waste;

  (3) Generates in a calendar month or accumulates at any time more than 1 kilogram of acute hazardous waste as specified in COMAR 26.13.02.05C(1), (2), (6,) and (7);

  (4) Generates in a calendar month or accumulates at any time:

    (a) Any containers identified in COMAR 26.13.02.19C that are larger than 20 liters in capacity;

    (b) 10 kilograms or more of inner liners from containers identified in COMAR 26.13.02.19C; or

    (c) 100 kilograms or more of any residue or contaminated soil, waste, or other debris resulting from the cleanup of a spill into or onto any land or water of any acute hazardous waste listed in COMAR 26.13.02.16—.19.

A-3. Requirements for Maryland-defined Small Quantity Generators.

  (1) A person who does not meet any of the criteria in §A-2 of this regulation is referred to as a “Maryland-defined small quantity generator”.

  (2) A Maryland-defined small quantity generator is subject to the requirements of COMAR 26.13.02.05 rather than this chapter, except:

    (a) For the requirements of Regulations .05-3—.05-5 of this chapter, regarding episodic generation; and

    (b) As specified in COMAR 26.13.02.05;

  (3) A person's eligibility to operate under the requirements applicable to Maryland-defined small quantity generators under COMAR 26.13.02.05 may be determined on a month-to-month basis, based on the amounts of hazardous waste and acute hazardous waste that:

    (a) Are generated in a given month; and

    (b) Have been accumulated on site at any time during that month.

  (4) Renotification Requirements for Maryland-defined Small Quantity Generators. Except as provided in Regulation .03-1 of this chapter, a person in possession of an EPA identification number issued under Regulation .03B of this chapter is not required to notify the Department of a change in the person's generator status if the generator status changes as a result of the person either newly qualifying as a Maryland-defined small quantity generator or no longer qualifying as a Maryland-defined small quantity generator. However, if the person expects the new status to remain unchanged for an extended period, the person is encouraged to notify the Department of the change in status by completing EPA Form 8700-12 with current information and submitting the revised form to the Department.

    (b) The criteria in COMAR 26.13.10.32E and F; and

  (2) Shall, if the healthcare facility is a very small quantity generator under federal regulations, as described in COMAR 26.13.03.01-1B, when counting all of the hazardous waste it generates in a calendar month, including both hazardous waste pharmaceuticals and non-pharmaceutical hazardous waste, refer to COMAR 26.13.10.32D(1)(c) and (d) to determine the applicable requirements for managing the generator’s hazardous waste pharmaceuticals and non-pharmaceutical hazardous waste.

#### Regulation .01-1 Federally-defined Hazardous Waste Generator Categories — Applicability in Maryland.

*COMAR 26.13.03.01-1*

A. Federal hazardous waste regulations in 40 CFR Parts 260—270 define and use the terms “very small quantity generator”, “small quantity generator”, and “large quantity generator”. This regulation:

  (1) Restates the definitions of the federally-defined hazardous waste generator categories;

  (2) Identifies certain requirements for which the applicability of the requirements to a Maryland generator of hazardous waste depends on the generator’s federally-defined hazardous waste generator category; and

  (3) Identifies certain reduced requirements that a Maryland generator of hazardous waste may take advantage of if the generator meets the federal definition of a small quantity generator.

B. Federal Categories for Hazardous Waste Generators. Under federal regulations at 40 CFR §260.10, a:

  (1) “Very small quantity generator” is a generator who generates less than or equal to the following amounts in a calendar month:

    (a) 100 kilograms (220 lbs) of nonacute hazardous waste;

    (b) 1 kilogram (2.2 lbs) of acute hazardous waste listed in 40 CFR §261.31 or 40 CFR §261.33(e); and

    (c) 100 kilograms (220 lbs) of any residue or contaminated soil, water, or other debris resulting from the cleanup of a spill, into or on any land or water, of any acute hazardous waste listed in 40 CFR §261.31 or 40 CFR §261.33(e);

  (2) “Small quantity generator” is a generator who generates that following amounts in a calendar month:

    (a) Greater than 100 kilograms (220 pounds) but less than 1,000 kilograms (2,200 pounds) of non-acute hazardous waste;

    (b) Less than or equal to 1 kilogram (2.2 pounds) of acute hazardous waste listed in 40 CFR §261.31 or 40 CFR §261.33(e); and

    (c) Less than or equal to 100 kilograms (220 pounds) of any residue or contaminated soil, water, or other debris resulting from the cleanup of a spill, into or on any land or water, of any acute hazardous waste listed in 40 CFR §261.31 or 40 CFR §261.33(e);

  (3) “Large quantity generator” is a generator who generates any of the following amounts in a calendar month:

    (a) Greater than or equal to 1,000 kilograms (2200 pounds) of non-acute hazardous waste;

    (b) Greater than 1 kilogram (2.2 pounds) of acute hazardous waste listed in 40 CFR §261.31 or 40 CFR §261.33(e) of this chapter; or

    (c) Greater than 100 kilograms (220 pounds) of any residue or contaminated soil, water, or other debris resulting from the cleanup of a spill, into or on any land or water, of any acute hazardous waste listed in 40 CFR §261.31 or 40 CFR §261.33(e).

B-1. Federal Generator Categories — Healthcare Facilities that Generate Hazardous Waste Pharmaceuticals.  To determine the applicable federally-defined hazardous waste generator category, a healthcare facility as defined in COMAR 26.13.01.03B shall refer to COMAR 26.13.10.32F.

C. A Maryland generator of hazardous waste shall:

  (1) Determine the applicable generator category under federal regulations using the procedures in 40 CFR §262.13, except that the generator shall:

    (a) Use the provisions of COMAR 26.13.02.05A(2) instead of the provisions of 40 CFR §262.13(c) in identifying waste that should not be counted in determining the federal generator category;

    (b) Exclude from the quantity of waste that determines the generator’s federal generator category any hazardous waste that is regulated as a hazardous waste under Maryland regulations but not federal regulations; and

    (c) Use the provisions of COMAR 26.13.02.05A(3)instead of the provisions of 40 CFR §262.13(d) in identifying the quantity of hazardous waste generated in a calendar month.

  (2) Use the federal generator category determined under §C(1) of this regulation for the purposes of:

    (a) Completing forms associated with:

      (i) Obtaining an EPA identification number under Regulation .03 of this chapter;

      (ii) Satisfying the renotification requirement of Regulation .03-1 of this chapter; and

      (iii) Reactivating an EPA identification number under Regulation .03-2 of this chapter;

  (5) The closure notification requirements of regulation .05-2B of this chapter.

#### Regulation .02 Hazardous Waste Determination — Generator's Obligations.

*COMAR 26.13.03.02*

A. A person who generates a solid waste, as defined in COMAR 26.13.02.02:

  (1) Shall:

    (a) Make an accurate determination as to whether that waste is a hazardous waste, with an “accurate determination” being a determination that allows the person to determine the requirements that are applicable to the waste and the generator of the waste under the provisions of COMAR 26.13.01—26.13.10 and federal hazardous waste regulations; and

    (b) Take into account, when the determination required by §A(1)(a) of this regulation is made, changes in the properties of the waste that are known or likely to occur before the ultimate disposition of the waste due to:

      (i) Exposure of the waste to the environment; or

      (ii) Other factors;

  (2) Shall, in complying with §A(1) of this regulation, make the determination for each solid waste:

    (a) At the point of waste generation before any dilution, mixing, or other alteration of the waste occurs; and

    (b) At any time in the course of the management of the waste when:

      (i) The properties of the waste have, or may have, changed as a result of exposure of the waste to the environment or because of other factors; and

      (ii) The change or potential change to the properties of the waste may cause a change to the classification of the waste made under §A(2)(a) of this regulation;

  (3) May, subject to the requirements of §A(4) of this regulation, designate the solid waste to be a hazardous waste if the person:

    (a) Assumes that the solid waste is a hazardous waste without having made a formal determination following the procedures in Regulation .02-1 of this chapter; or

    (b) Has decided to voluntarily designate and manage the solid waste as a hazardous waste despite a determination, using the procedures in Regulation .02-1 of this chapter, that the waste does not have to be managed as a hazardous waste; and

  (4) Shall, if the person has made the assumption that the waste is hazardous, as specified in §A(3)(a) of this regulation:

    (a) Determine whether the waste is an acute hazardous waste, as specified in Regulation .02-1 of this chapter;

    (b) Comply with the record keeping requirements of Regulation .02-2 of this chapter, if applicable; and

    (c) Identify all hazardous wastes numbers that may be associated with the waste, in accordance with the requirements of §D(1) of this regulation, if applicable.

B. A person making the determination required by §A of this regulation shall:

  (1) Follow the procedures specified in Regulation .02-1 of this chapter in characterizing the waste; and

  (2) Unless the person qualifies as a Maryland-defined small quantity generator, comply with the record keeping requirements specified in Regulation .02-2 of this chapter.

C. If the result of the determination required by §A of this regulation is that the waste is a hazardous waste, the generator of the waste shall refer to COMAR 26.13.02, 26.13.05, 26.13.06, 26.13.09, and 26.13.10 for possible exclusions or restrictions pertaining to management of the specific waste.

D. A person who generates hazardous waste and who does not meet the criteria to be considered a Maryland-defined small quantity generator shall:

  (1) Identify, for each hazardous waste generated, all hazardous waste numbers and EPA hazardous waste numbers, as specified in COMAR 26.13.02.11—.19, that apply to the hazardous waste; and

  (2) Comply with the record keeping requirements of Regulation .02-2 of this chapter.

Agency Note: information from the complete determination of applicable hazardous waste numbers required by §D(1) of this regulation is needed in order to comply with the container marking requirements of Regulation .03-10 of this chapter.

#### Regulation .02-1 Hazardous Waste Determination — Procedures.

*COMAR 26.13.03.02-1*

A. This regulation specifies procedures that a person shall follow in determining whether a solid waste is a hazardous waste, and establishes record keeping requirements with respect to hazardous waste determinations.

B. In order to determine whether a solid waste is a hazardous waste, a person shall, in accordance with the requirements of §§C—D of this regulation:

  (1) Determine if the waste is excluded from regulation under COMAR 26.13.02.04—.04-5;

  (2) If the waste is not excluded from regulation under COMAR 26.13.02.04—.04-5:

    (a) Determine if the waste is listed as a hazardous waste in COMAR 26.13.02.15—.19; and

    (b) Determine whether the waste exhibits any of the characteristics of hazardous waste specified in COMAR 26.13.02.10—.14.

C. To determine if a waste is listed as a hazardous waste in COMAR 26.13.02.15—.19, a person shall:

  (1) Use knowledge of the waste to determine if the waste meets any of the listing descriptions in COMAR 26.13.02.10—.14; and

  (2) Ensure that the information that the person uses in making the determination is sufficient to result in an accurate characterization that can serve as the basis for determining the management standards that apply, such as information on:

    (a) The origin of the waste;

    (b) Waste composition;

    (c) The process that produced the waste;

    (d) The feedstock for the process from which the waste is derived; and

    (e) Other reliable and relevant information.

Agency Note: Even if the waste is listed as a hazardous waste, the generator still has an opportunity under 40 CFR 260.20 and 260.22 for a waste listed as hazardous by the federal government, and COMAR 26.13.01.04A and C for a Maryland-only listed waste, to demonstrate that the waste from the generator’s particular facility or operation does not meet the criteria for listing. However, the waste must be managed as a hazardous waste until a petition to delist the waste under these provisions is successful.

D. Determining Whether a Waste Exhibits a Characteristic of Hazardous Waste.

  (1) To determine whether a waste exhibits a characteristic of hazardous waste, a person shall:

    (a) Apply knowledge of the characteristics of the waste in accordance with §D(2) of this regulation;

    (b) Test the waste in accordance with §D(3) of this regulation; or

    (c) Use a combination of both application of knowledge of the waste and testing of the waste.

  (2) In using knowledge of waste characteristics as the basis for determining whether a waste exhibits any of the characteristics of hazardous waste defined in COMAR 26.13.02.10—.14, a person:

    (a) Shall apply knowledge of the hazard characteristics of the waste in light of the materials and the processes used to generate the waste;

    (b) Shall ensure that the information that the person uses in making the determination is sufficient to result in an accurate characterization that can serve as the basis for determining the management standards that apply, relying on such things as:

      (i) Process knowledge, such as information about the identities and properties of chemical feedstocks and other inputs to the production process and the transformations that occur as part of the process;

E-1. Use of the Electronic Manifest.

  (1) Legal Equivalence to Paper Manifests. For the purposes of COMAR 26.13.01—.10:

    (a) An electronic manifest that is obtained, completed, and transmitted in accordance with §A(1)(b) of this regulation, and used in accordance with this section instead of using EPA Forms 8700-22 and 8700-22A, is the legal equivalent of paper manifest forms bearing handwritten signatures and satisfies for all purposes any requirement to obtain, complete, sign, provide, use, or retain a manifest;

    (b) A requirement to sign a manifest or manifest certification by hand, or to obtain a handwritten signature, is satisfied by signing with or obtaining a valid and enforceable electronic signature within the meaning of §E-2 of this regulation;

    (c) A requirement to give, provide, send, forward, or return to another person a copy of the manifest is satisfied when an electronic manifest is transmitted to the other person by submission to the electronic manifest system;

    (d) A requirement for a generator to keep or retain a copy of a manifest is satisfied by retention of a signed electronic manifest in the generator's account on the national electronic manifest system if the copy is readily available for viewing and production if requested by an inspector representing the Department or EPA; and

    (e) If a generator is unable to produce an electronic manifest for inspection in accordance with §E-1(1)(d) of this regulation, the generator is not considered to be in violation of the requirement to have a copy of the manifest readily available if the generator can demonstrate that the inability to produce the electronic manifest is due exclusively to a technical difficulty with the electronic manifest system for which the generator bears no responsibility.

  (2) Accessing the Electronic Manifest System. A generator may participate in the electronic manifest system either by accessing the electronic manifest system from the generator's own electronic equipment, or by accessing the electronic manifest system from portable equipment brought to the generator's site by the transporter who accepts the hazardous waste shipment from the generator for off-site transportation.

  (3) Restriction on Use of Electronic Manifests.

    (a) Except as provided in §E-1(3)(b) of this regulation, a generator may use an electronic manifest for the tracking of waste shipments involving any hazardous waste only if it is known at the time the manifest is originated that all waste handlers named on the manifest participate in the use of the electronic manifest.

    (b) A generator may sign by hand and retain a paper copy of the manifest signed by hand by the initial transporter, instead of executing the generator copy electronically, thereby enabling the transporter and subsequent waste handlers to execute the remainder of the manifest copies electronically.

  (4) Requirement for One Printed Copy. To the extent that the U.S. Department of Transportation hazardous materials regulation on shipping papers for carriage by public highway requires shippers of hazardous materials to supply a paper document for compliance with 49 CFR §177.817, a generator originating an electronic manifest shall also provide the initial transporter with one printed copy of the electronic manifest.

  (5) Special Procedures When the Electronic Manifest System Is Unavailable. If a generator has prepared an electronic manifest for a hazardous waste shipment, but the electronic manifest system becomes unavailable for any reason before the time that the initial transporter has signed electronically to acknowledge the receipt of the hazardous waste from the generator, then the generator shall:

    (a) Obtain and complete a paper manifest and, if necessary, a continuation sheet (EPA Forms 8700-22 and 8700-22A) in accordance with the manifest instructions; and

    (b) Use the paper forms identified in §E-1(5)(a) of this regulation from this point forward for the shipment in accordance with the requirements of §E of this regulation.

  (6) Special Procedures for Electronic Signature Methods Undergoing Tests. If a generator has prepared an electronic manifest for a hazardous waste shipment, and signs this manifest electronically using an electronic signature method that is undergoing pilot or demonstration tests aimed at demonstrating the practicality or legal dependability of the signature method, then the generator shall also sign with an ink signature the certification of the generator or offeror on the printed copy of the manifest provided under §E-1(4) of this regulation.

  (7) Post-Receipt Manifest Data Corrections.

    (a) After facilities have certified to the receipt of hazardous wastes by signing Item 20 of the manifest, any post-receipt data corrections may be submitted at any time by any interested person named on the manifest, such as a waste handler; and

      (i) The EPA identification number, name, and address of the generator;

      (ii) The calendar year covered by the report;

      (iii) The EPA identification number, name, and address for each off-site treatment, storage, or disposal facility in the United States to which waste was shipped during the year;

      (iv) The name and EPA identification number of each transporter used during the reporting year for shipments to a treatment, storage, or disposal facility within the United States;

      (v) For shipments of hazardous waste to a treatment, storage, or disposal facility within the United States, the description, the EPA or State hazardous waste number from COMAR 26.13.02, the DOT hazard class, and the quantity of each hazardous waste listed by the EPA identification number of each off-site facility to which waste was shipped;

      (vi) A description of the efforts undertaken during the year to reduce the volume and toxicity of waste generated;

      (vii) Except as provided in §B4 of this regulation, a description of the changes in the volume and toxicity of waste actually achieved during the year in comparison to previous years; and

      (viii) The certification on EPA Form 8700-13A/B signed by the generator or authorized representative.

  (4) Information required by §B(1)(d)(vii) of this regulation on changes in volume and toxicity of waste actually achieved in comparison to years before 1984 is only required to the extent that this information is available.

  (5) The reporting requirement of this section does not apply to person who qualifies as a Maryland-defined small quantity generator in every month of a year for which a report under this section would otherwise have to be submitted, but does apply if the person did not qualify as a Maryland-defined small quantity generator in any month of that year.

C. Exception Reporting.

  (1) A generator who does not receive a copy of the manifest with the handwritten signature of the owner or operator of the designated facility within 35 days of the date the waste was accepted by the initial transporter shall contact the transporter and/or the owner or operator of the designated facility to determine the status of the hazardous waste.

  (2) A generator shall submit an exception report to the Secretary if the generator has not received a copy of the manifest with the handwritten signature of the owner or operator of the designated facility within 45 days of the date the waste was accepted by the initial transporter and include in the exception report the following:

    (a) A legible copy of the manifest for which the generator does not have confirmation of delivery;

    (b) A cover letter signed by the generator or his authorized representative explaining the efforts taken to locate the hazardous waste and the results of those efforts.

  (3) If the designated facility is located out-of-State in a state which administers the federal program, the generator who does not receive a copy of the manifest as described in §C(1) of this regulation, shall submit an exception report to that state's approving authority as specified in §C(2) of this regulation. If that state's program is administered by the EPA, the Report shall be forwarded to the EPA Regional Administrator for the region in which the designated facility is located.

  (4) For a rejected shipment of hazardous waste or container residues contained in non-empty containers that a designated facility forwards to an alternate facility using a new manifest, following the procedures of COMAR 26.13.05.05C(5)(b)(i)—(ix), the generator shall :

    (a) Comply with the requirements of §C(1) and (2) of this regulation for the shipment that is forwarding the material from the designated facility to the alternate facility instead of for the shipment from the generator to the designated facility; and

    (b) In complying with §C(1) and (2) of this regulation with respect to the shipment to the alternate facility:

      (i) Take the required actions based on whether the generator has received, by the specified deadlines, a copy of the manifest with the handwritten signature of the owner or operator of the alternate facility rather than a copy of the manifest with the handwritten signature of the owner or operator of the original designated facility; and

      (ii) Determine whether the 35-day and 45-day deadlines have passed by comparing the current date to the date that the waste was accepted by the initial transporter forwarding the hazardous waste shipment from the designated facility to the alternate facility.

D. Additional Reporting. The Secretary, as he deems necessary, may require generators to furnish additional reports concerning the quantities and disposition of wastes identified or listed in COMAR 26.13.02.
