This chapter identifies those solid wastes which are subject to regulation as hazardous wastes under COMAR 26.13.03—26.13.10. In this chapter: Regulations .01—.07 define the terms “solid waste” and “hazardous waste”, identify those wastes which are excluded from regulation under COMAR 26.13.03—26.13.07, 26.13.09 and 26.13.10 and establish special management requirements for hazardous waste produced by small quantity generators and hazardous waste which is used, re-used, recycled, or reclaimed. Regulations .08 and .09 set forth the criteria used by the Department to identify characteristics of hazardous waste and to list particular hazardous wastes. Regulations .10—.14 identify characteristics of hazardous waste. Regulations .15—.19 list particular hazardous wastes. General. The definition of solid waste contained in this chapter applies only to wastes that also are hazardous for purposes of this subtitle. For example, it does not apply to materials such as nonhazardous scrap, paper, textiles, or rubber that are not otherwise hazardous wastes and that are recycled. This chapter identifies only some of the materials which are solid wastes and hazardous wastes under Environment Article, Title 7, Subtitle 2, Annotated Code of Maryland. Definitions. For the purposes of Regulations .02, .04, and .06 of this chapter, the following terms have the meanings indicated: By-Product. “By-product” means a material that is not one of the primary products of a production process and is not solely or separately produced by the production process, such as slags, distillation column bottoms, or other process residues. “By-product” does not include a co-product that is produced for the general public's use and is ordinarily used in the form produced by the process. “Excluded scrap metal” means processed scrap metal, unprocessed home scrap metal, and unprocessed prompt scrap metal. “Home scrap metal” means scrap metal as generated by steel mills, foundries, and refineries, and includes, for example, turnings, cuttings, punchings, and borings. Material Accumulated Speculatively. “Material accumulated speculatively” means a material that is accumulated before being recycled. “Material accumulated speculatively” does not include a material for which the person accumulating the material can show that the material is potentially recyclable and has a feasible means of being recycled, and that during the calendar year which commences on January 1, the amount of material that is recycled or transferred to a different site for recycling equals at least 75 percent by weight or volume of the amount of that material accumulated at the beginning of the period, subject to the following: The person shall have placed the material in a storage unit that has a label indicating the first date that the material began to be accumulated, or, if placing a label on the storage unit is not practicable, the person shall have documented the accumulation period through an inventory log or other appropriate method; In calculating the percentage of turnover, the 75 percent requirement is to be applied to each material of the same type, such as slags from a single smelting process, that is recycled in the same way, such as by recovering the same material from the recyclable material, or by using the material in the same way; Materials accumulating in units that would be exempt from regulation under Regulation .04-2 of this chapter are not to be included in making the calculation; Materials that are already defined as solid wastes are not to be included in making the calculation; and A material is no longer in the category of material being accumulated speculatively once it has been removed from accumulation for recycling. Processed Scrap Metal. “Processed scrap metal” means scrap metal which has been manually or physically altered to either separate it into distinct materials to enhance economic value or to improve the handling of materials. “Processed scrap metal” includes, but is not limited to, scrap metal which has been baled, shredded, sheared, chopped, crushed, flattened, cut, melted, or separated by metal type, and fines, drosses, and related materials which have been agglomerated. “Processed scrap metal” does not include shredded circuit boards being sent for recycling, which are excluded from the definition of solid waste under Regulation .04A(12) of this chapter. Prompt Scrap Metal. “Prompt scrap metal”, also known as “industrial scrap metal” or “new scrap metal”, means scrap metal as generated by the metal working or metal fabrication industries. “Prompt scrap metal” includes scrap metal such as turnings, cuttings, punchings, and borings. Reclaimed Material. “Reclaimed material” means material that is processed to recover a usable product or is regenerated. “Reclaimed material” includes, for example, recovery of lead values from spent batteries and regeneration of spent solvents. “Recycled material” means material that is used, reused, or reclaimed. “Reused or used material” means a material that is employed in either one of the following: As an ingredient including use as an intermediate, in an industrial process to make a product, such as distillation bottoms from one process used as feedstock in another process, except that a material does not satisfy this condition if distinct components of the material are recovered as separate end products, as when metals are recovered from metal-containing secondary materials; or In a particular function or application as an effective substitute for a commercial product such as spent pickle liquor used as phosphorus precipitant and sludge conditioner in wastewater treatment. “Scrap metal” means bits and pieces of metal parts such as bars, turnings, rods, sheets, or wire or metal pieces that may be combined together with bolts or soldering such as radiators, scrap automobiles, or railroad box cars, which when worn or superfluous can be recycled. “Sludge” has the meaning stated in COMAR 26.13.01.03B(72). “Spent material” means any material that has been used and as a result of contamination can no longer serve the purpose for which it was produced without processing. Solid Waste and Discarded Material. A solid waste is any discarded material that is not excluded by Regulation .04 of this chapter or that is not excluded by a variance granted under COMAR 26.13.01.04D and E. A discarded material is any material which is: Abandoned, as explained in §B of this regulation; Recycled, as explained in §C of this regulation; Considered inherently waste-like, as explained in §D of this regulation; or A military munition identified as a solid waste in COMAR 26.13.10.27B. Materials are solid waste if they are abandoned. For purposes of this subtitle, “abandoned” means: Disposed of; Burned or incinerated; Accumulated, stored, or treated (but not recycled) before or instead of being abandoned by being disposed of, burned, or incinerated; or Sham recycled, as explained in §H of this regulation. Materials are solid wastes if they are recycled, or accumulated, stored, or treated before recycling, as follows: Used in a Manner Constituting Disposal. Except as provided in §C(1)(b) of this regulation, materials noted with an asterisk in §G of this regulation, column 1 of Table 1, are solid wastes when they are: Applied to or placed on the land in a manner that constitutes disposal; or Used to produce products that are applied to or placed on the land or are otherwise contained in products that are applied to the land (in which case the product itself remains a solid waste). Commercial chemical products that exhibit a characteristic of hazardous waste or that are listed in Regulation .19 of this chapter are not solid wastes if they are applied to the land and that is their ordinary manner of use. Materials Burned for Energy Recovery. Except as provided in §C(2)(b) of this regulation, materials noted with an asterisk in §G of this regulation, column 2, are solid wastes when they are: Burned to recover energy; Used to produce a fuel; Contained in fuels, in which case the fuel itself remains a solid waste. Commercial chemical products that exhibit a characteristic of hazardous waste or that are listed in Regulation .19 of this chapter are not solid wastes if they are themselves fuels. Materials Reclaimed. Materials noted with an asterisk in §G, column 3 of Table 1 are solid wastes when reclaimed. Materials Accumulated Speculatively. Materials noted with an asterisk in §G, column 4 of Table 1 are solid wastes when accumulated speculatively. Inherently Waste-Like Materials. The following materials are solid wastes when they are recycled in any manner: Hazardous Waste Nos. F020, F021, unless otherwise used as an ingredient to make a product at the site of generation, and F022, F023, F026, and F028. The Secretary shall use the following criteria to add wastes to the list in §D(1): The materials are ordinarily disposed of, burned, or incinerated; The materials contain toxic constituents listed in Regulation .24 of this chapter and these constituents are not ordinarily found in raw materials or products for which the materials substitute, or are found in raw materials or products in smaller concentrations, and are not used or reused during the recycling process; or The materials may pose a substantial hazard to human health and the environment when recycled. Materials That Are Not Solid Waste When Recycled. Materials are not solid wastes when they can be shown to be recycled by being: Used or reused as ingredients in an industrial process to make a product, provided the materials are not being reclaimed; Used or reused as effective substitutes for commercial products; or Returned to the original process from which they are generated, without first being reclaimed. The material shall be returned as a substitute for raw material feedstock, and the process shall use raw materials as principal feedstocks, in order for this paragraph to apply. The following materials are solid wastes, even if the recycling involves use, reuse, or return to the original process, described in §E(1), of this regulation: Materials used in a manner constituting disposal, or used to produce products that are applied to the land; Materials burned for energy recovery, used to produce a fuel, or contained in fuels; Materials accumulated speculatively; or Materials listed in §D(1) of this regulation. Documentation of Claims That Materials Are Not Solid Wastes or Are Conditionally Exempt from Regulation. A respondent in an action to enforce regulations implementing Environment Article, Title 7, Subtitle 2, Annotated Code of Maryland, who raises a claim that a certain material is not a solid waste, or is conditionally exempt from regulation, shall demonstrate that: There is a known market or disposition for the material; and The respondent meets the terms of the exclusion or exemption. To satisfy the requirements of §F(1) of this regulation, a person shall provide appropriate documentation, such as contracts showing that a second person uses the material as an ingredient in a production process, to demonstrate that the material is not a waste, or is exempt from regulation. In addition to meeting the requirements of §F(2) of this regulation, owners or operators of facilities claiming that they actually are recycling materials shall show that they have the necessary equipment to do so. Table 1. Sham Recycling. A hazardous secondary material found to be sham recycled, as defined in §H(2) of this regulation, is considered discarded and a solid waste. “Sham recycling” means recycling that is not legitimate, as determined in accordance with COMAR 26.13.01.04L.

A solid waste which is not excluded from regulation under §A(1) of this regulation becomes a hazardous waste when any of the following events occurs: In the case of a waste listed in Regulations .15—.19 of this chapter, when the waste first meets the listing description set forth in Regulations .15—.19 of this chapter; In the case of a mixture of solid waste and one or more listed hazardous wastes, when a hazardous waste listed in Regulations .15—.19 of this chapter is first added to the solid waste; In the case of any other waste (including a waste mixture), when the waste exhibits any of the characteristics identified in Regulations .10—.14 of this chapter. Unless and until it meets the criteria of §D of this regulation: A hazardous waste will remain a hazardous waste. Any solid waste generated from the treatment, storage, or disposal of a hazardous waste, including any sludge, spill residue, ash, emission control dust, or leachate but not including precipitation runoff, is a hazardous waste, except: As otherwise provided in: §C-1 of this regulation; or §F(1)(c) of this regulation, concerning hazardous wastes listed solely for one or more of the characteristics of ignitability, corrosivity, or reactivity; and Materials that are reclaimed from solid waste and that are used beneficially are not hazardous wastes under this provision unless the reclaimed material is burned for energy recovery or used in a manner constituting disposal.

Except as specified in COMAR 26.13.10.06—.25, the wastes listed in §B of this regulation are exempt from regulation under COMAR 26.13.03—26.13.07, COMAR 26.13.09, and COMAR 26.13.10.01—.05, and, therefore, are not fully regulated as hazardous waste. The following wastes are subject to regulation under COMAR 26.13.10.06.25: Batteries, as described in COMAR 26.13.10.07; Pesticides, as described in COMAR 26.13.10.08; Mercury-containing equipment, lamps, or PCB-containing lamp ballasts, each as described in COMAR 26.13.10.09; and Aerosol cans, as described in COMAR 26.13.10.09-1. The Secretary shall identify and define a characteristic of hazardous waste in Regulations .10—.14 only upon determining that: A solid waste that exhibits the characteristic may: Cause, or significantly contribute to, an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness; or Pose a substantial present or potential hazard to human health or the environment when it is improperly treated, stored, transported, disposed of or otherwise managed; and The characteristic can be: Measured by an available standardized test method which is reasonably within the capability of generators of solid waste or private sector laboratories that are available to serve generators of solid waste; or Reasonably detected by generators of solid waste through their knowledge of their waste. The Secretary shall list a solid waste as a hazardous waste only upon determining that the solid waste meets one of the following criteria: It exhibits any of the characteristics of hazardous waste identified in Regulations .10—.14 of this chapter. It has been found to be fatal to humans in low doses or, in the absence of data on human toxicity, it has been shown in studies to have an oral LD50 toxicity (rat) of less than 50 milligrams per kilogram, an inhalation LC50 toxicity (rat) of less than 2 milligrams per liter, or a dermal LD50 toxicity (rabbit) of less than 200 milligrams per kilogram or is otherwise capable of causing or significantly contributing to an increase in serious irreversible, or incapacitating reversible, illness. Waste listed in accordance with these criteria will be designated Acute Hazardous Waste. It contains any of the toxic constituents listed in Regulation .24 of this chapter and, after considering the following factors, the Secretary concludes that the waste is capable of posing a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed: The nature of the toxicity presented by the constituent. The concentration of the constituent in the waste. The potential of the constituent or any toxic degradation product of the constituent to migrate from the waste into the environment under the types of improper management considered in §A(3)(g), of this regulation. The persistence of the constituent or any toxic degradation product of the constituent. The potential for the constituent or any toxic degradation product of the constituent to degrade into non-harmful constituents and the rate of degradation. The degree to which the constituent or any degradation product of the constituent bioaccumulates in ecosystems. The plausible types of improper management to which the waste could be subjected. The quantities of the waste generated at individual generation sites or on a regional or national basis. The nature and severity of the human health and environmental damage that has occurred as a result of the improper management of wastes containing the constituent. Actions taken by other governmental agencies or regulatory programs based on the health or environmental hazard posed by the waste or waste constituents. Such other factors as may be appropriate. Substances will be listed in Regulation .24 of this chapter, only if they have been shown in scientific studies to have toxic, carcinogenic, mutagenic, or teratogenic effects on humans or other life forms. Wastes listed in accordance with these criteria will be designated Toxic Wastes. The Secretary may list classes or types of solid waste as hazardous waste if he has reason to believe that individual wastes, within the class or type of waste, typically or frequently are hazardous under the definition of hazardous waste found in COMAR 26.13.02. The Secretary will use the criteria for listing specified in this subsection to establish the exclusion limits referred to in Regulation .05C of this chapter. A solid waste, as defined in Regulation .02 of this chapter, which is not excluded from regulation as a hazardous waste under Regulation .04-1 of this chapter is a hazardous waste if it exhibits any of the characteristics identified in this regulation and in Regulations .11—.14 of this chapter. A hazardous waste which is identified by a characteristic in Regulations .10—.14 of this chapter is assigned every EPA Hazardous Waste Number that is applicable as set forth in the respective characteristic. This number or these numbers shall be used in complying with the notification requirement of §3010 of RCRA and with certain record keeping and reporting requirements under COMAR 26.13.03—26.13.07 and 26.13.09. For purposes of Regulations .10—.14 of this chapter, the Secretary will consider a sample obtained using any of the applicable sampling methods specified in Regulation .20 to be a representative sample within the meaning of COMAR 26.13.01. A solid waste exhibits the characteristic of ignitability if a representative sample of the waste has any of the following properties: Except as provided in §A-1 of this regulation, it is a liquid that has a flash point less than 60°C (140°F), as determined by using one of the methods specified in 40 CFR §261.21(a)(1); It is not a liquid and is capable, under standard temperature and pressure, of causing fire through friction, absorption of moisture, or spontaneous chemical changes and, when ignited, burns so vigorously and persistently that it creates a hazard; It is an ignitable compressed gas as described in §C(2) and (3) of this regulation; or It is an oxidizer as defined in §C(4) of this regulation. A liquid that is an alcohol-containing solution that contains less than 24 percent alcohol by volume and at least 50 percent water by weight is not considered to exhibit the characteristic of ignitability under §A(1) of this regulation. A solid waste that exhibits the characteristic of ignitability has the EPA Hazardous Waste Number of D001. For the purposes of this regulation: “Aerosol” means any nonrefillable receptacle that: Contains a gas that has been compressed, liquefied, or dissolved under pressure, the sole purpose of which is to expel a liquid, paste, or powder that is: Nonpoisonous, that is, it is not a poisonous material under 49 CFR §173.132; or A Division 6.1 Packing Group III material under 49 CFR §173.133; and Is fitted with a self-closing release device that allows the contents of the receptacle to be ejected by the gas described in §C(1)(a) of this regulation; “Compressed gas” means: A contained material or mixture that has within the container: An absolute pressure exceeding 40 pounds per square inch at 70°F; or An absolute pressure exceeding 104 pounds per square inch at 130°F regardless of the pressure at 70°F; or Any liquid flammable material having a vapor pressure exceeding 40 pounds per square inch absolute at 100°F as determined by the test method in 40 CFR §261.21(a)(3)(i); A compressed gas shall be characterized as ignitable if any of the following criteria are met: At atmospheric temperature and pressure, using the test method identified in 49 CFR §173.115(a), either: A mixture of 13 percent or less by volume of the gas with air forms a flammable mixture; or The flammable range for mixtures of the gas with air is wider than 12 percent regardless of the lower limit; It meets the definition of “flammable gas (Division 2.1)” under 49 CFR §173.115(a); or It is an aerosol as described in §C(1) of this regulation and the compressed gas meets the definition of “flammable gas (Division 2.1)” under 49 CFR §173.115(a) and (l); “Oxidizer” means a substance such as a chlorate, permanganate, inorganic peroxide, organic peroxide, or a nitrate that yields oxygen readily to stimulate the combustion of organic matter; and “Organic peroxide”: Means an organic compound containing the bivalent -O-O- structure and which may be considered a derivative of hydrogen peroxide where one or more of the hydrogen atoms have been replaced by organic radicals; and Does not include a material that: Meets the definition of a Division 1.1, 1.2, or 1.3 explosive, as defined in 49 CFR §173.50 and 49 CFR §173.53, in which case the material is classed as an explosive; Is forbidden to be offered for transportation by 49 CFR §172.101 or 49 CFR §173.21; Contains an organic peroxide but it is determined that the predominant hazard of the material is other than that of an organic peroxide; or Does not present a hazard in transportation according to data on file with the U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration, or its successor agency. This regulation describes the equipment and procedures that shall be used in evaluating the criteria of Regulation .11C(3)(c)(ii)—(iv) of this chapter to determine whether an aerosol is ignitable. Flame Projection Test. Equipment. The test equipment for the Flame Projection Test consists of a base 4 inches wide and 2 feet long. A 30-inch rule with inches marked is supported horizontally on the side of the base and about 6 inches above it. A plumber's candle of such height that the top third of the flame is at the height of the horizontal rule is placed at the zero point in the base. Procedure. The test is conducted in a draft-free area that can be ventilated and in which the atmosphere can be cleared between each test. The self-pressurized container being tested is placed at a distance of 6 inches from the ignition source and the spray is jetted into the top third of the flame with the valve opened fully for periods of 15 to 20 seconds. The length of the flame projection from the candle position is read on the horizontal scale. Three or more readings are taken on each sample and the average of the readings is taken as the result of the test. Samples are also tested with the container valve in partially open positions to test for “burning back” to the valve. Drum Tests. Equipment. The equipment for the open drum test and the closed drum test consists of a 55-gallon open-head steel drum or similar container that is placed on its side and fitted with a hinged cover over the open end that will open at a pressure of 5 pounds per square inch. The closed or solid end of the container is equipped with one shuttered opening at the top. The shuttered opening is for the introduction of the spray being tested. The opening is approximately 2 inches from the edge of the drum head and is 2 inches in diameter. There is a safety glass or plastic window 6 inches square in the center of the solid end. A lighted plumber's candle is placed inside the drum on the lower side and midway between the ends. Drum Test Procedures. The Open Drum Test and the Closed Drum Test shall be conducted in the open and when the temperature is between 60°F and 80°F. Open Drum Test. This test is conducted with the hinged end of the test equipment in a completely open position and with the shutter closed. The spray from the dispenser of the item being tested, with valve opened fully, is directed into the upper half of the open end and above the ignition source for 1 minute. Any significant propagation of flame through the vapor-air mixture away from the ignition source shall be considered a positive result, except that any minor and unsustained burning in the immediate area of the ignition source is not considered a positive result. Closed Drum Test. This test is conducted with the hinged cover of the test equipment dropped into position to rest freely against the end of the equipment and to close the open end of the drum to make a seal that is reasonably secure, but not necessarily air-tight. The shutter is opened and the spray is jetted into the drum through the shutter with the valve fully opened for 1 minute. After clearing the atmosphere in the drum, the jetting is repeated similarly three times. Any explosion or rapid burning of the vapor-air mixture sufficient to cause the hinged cover to move is considered a positive result. A solid waste exhibits the characteristic of corrosivity if a representative sample of the waste has either of the following properties: It is aqueous and has a pH less than or equal to 2 or greater than or equal to 12.5, as determined by a pH meter using Method 9040 in “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods”, EPA Publication SW-846, as incorporated by reference in COMAR 26.13.01.05A(4); It is a liquid and corrodes steel (SAE 1020) at a rate greater than 6.35 mm (0.250 inch) per year at a test temperature of 55°C (130°F) as determined by the test method specified in NACE (National Association of Corrosion Engineers) Standard TM-01-69* as standardized in “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods”, EPA Publication SW-846, which is incorporated by reference in COMAR 26.13.01.05A(4). * The NACE Standard is available from the National Association of Corrosion Engineers, P.O. Box 986, Katy, Texas 77450. A solid waste that exhibits the characteristics of corrosivity has the EPA Hazardous Waste Number of D002. A solid waste exhibits the characteristic of reactivity if a representative sample of the waste has any of the following properties: It is normally unstable and readily undergoes violent change without detonating; It reacts violently with water; It forms potentially explosive mixtures with water; When mixed with water, it generates toxic gases, vapors, or fumes in a quantity sufficient to present a danger to human health or the environment; 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; It is capable of detonation or explosive reaction if it is subjected to a strong initiating source or if heated under confinement; It is readily capable of detonation or explosive decomposition or reaction at standard temperature and pressure; It is a: Forbidden explosive as defined in 49 CFR §173.54; or Division 1.1, 1.2, or 1.3 explosive as defined in 49 CFR §173.50 and 173.53. A solid waste that exhibits the characteristic of reactivity has the EPA Hazardous Waste Number of D003. A solid waste, except manufactured gas plant waste, exhibits the characteristic of toxicity if, using the Toxicity Characteristic Leaching Procedure, Test Method 1311 in “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods”, EPA Publication SW-846, which is incorporated by reference in COMAR 26.13.01.05A(4), the extract from a representative sample of the waste contains any of the contaminants listed in Table 1 at the concentration equal to or greater than the respective value given in that table. When the waste contains less than 0.5 percent filterable solids, the waste itself, after filtering using the methodology outlined in Test Method 1311, is considered to be the extract for the purpose of this section. A solid waste that exhibits the characteristic of toxicity has the EPA hazardous waste number specified in the following Table 1, which corresponds to the toxic contaminant causing it to be hazardous: Clarification Concerning Manufactured Gas Plant Waste. Manufactured gas plant waste that would exhibit the characteristic of toxicity in the absence of the exception provided in §A of this regulation may not be managed in a landfill that is permitted, licensed, or registered to manage municipal solid waste. A solid waste is a hazardous waste if it is listed in Regulations .16—.19 unless it has been excluded from this list under COMAR 26.13.01.04A and B. The Secretary will indicate his basis for listing the classes or types of wastes listed in Regulations .16—.19 of this chapter by employing one or more of the following hazard codes: Ignitable waste ------------------------------------------(i); Corrosive waste ---------------------------------------- (C); Reactive waste ----------------------------------------- (R); Toxicity characteristic waste ------------------------- (E); Acute hazardous waste -------------------------------- (H); Toxic waste --------------------------------------------- (T). Regulation .23 of this chapter identifies the constituent which caused the Secretary to list the waste as a toxicity characteristic waste (E) or toxic waste (T) in Regulations .16 and .17 of this chapter. Each hazardous waste listed in Regulations .16—.19 of this chapter is assigned a Hazardous Waste Number which precedes the name of the waste. This number shall be used in complying with the notification requirements, and certain record-keeping and reporting requirements under COMAR 26.13.03—26.13.06 and 26.13.09. The following hazardous wastes also listed in Regulations .16 and .17 of this chapter are subject to the exclusion limits for acute hazardous wastes established in Regulation .05 of this chapter: F020, F021, F022, F023, F026, and F027 of Regulation .16 of this chapter; and K991—K999 of Regulation .17 of this chapter. As qualified by §§B and D of this regulation, the solid wastes listed in the “Hazardous Waste” column of Table 1 of this regulation are listed as hazardous wastes from nonspecific sources unless they are excluded under: 40 CFR §260.20 and 40 CFR §260.22, listed in Appendix IX to 40 CFR Part 261, and referenced in Regulation .25 of this chapter; COMAR 26.13.01.04A and C and listed in Regulation .26 of this chapter; or Section C or D of this regulation: *(I,T) should be used to specify mixtures containing ignitable and toxic constituents. Clarifications for Listing of Wastes from Nonspecific Sources — Hazardous Waste Numbers F037 and F038. For the purpose of the F037 and F038 listings in §A of this regulation, “oil/water/solids” means oil, water, or solids, or any combination of these. Aggressive Biological Treatment. For the purposes of the F037 and F038 listings, “aggressive biological treatment units” means units which employ one of the following four treatment methods: Activated sludge; Trickling filter; Rotating biological contactor for the continuous accelerated biological oxidation of wastewaters; or High rate aeration. For the purposes of §B(2)(a) of this regulation, “high rate aeration” means a system of surface impoundments or tanks, in which intense mechanical aeration is used to completely mix the wastes and enhance biological activity, in which the units employ a minimum of 6 horsepower per 1,000,000 gallons of treatment volume, and in which either the: Hydraulic retention time is not longer than 5 days; or Hydraulic retention time is not longer than 30 days and the unit does not generate a sludge that is a hazardous waste by the toxicity characteristic. Generators and treatment, storage, and disposal facilities have the burden of proving that their sludges are exempt from listing as F037 and F038 wastes. If seeking to exempt a sludge from listing as F037 and F038 waste, a person shall maintain, in an operating record or in other on-site records, documents, and data sufficient to prove that the: Unit is an aggressive biological treatment unit as defined in §B(2) of this regulation; and Sludges for which an exemption from the definitions of F037 or F038, or both, is being sought were actually generated in the aggressive biological treatment unit. For the purposes of the F037 listing, sludges are considered to be generated at the moment of deposition in the unit, when “deposition” means at least a temporary cessation of lateral particle movement. For the F038 listing: Sludges are considered to be generated at the moment of deposition in the unit, when “deposition” means at least a temporary cessation of lateral particle movement; and Floats are considered to be generated at the moment they are formed in the top of the unit. Deletion of the F032 Hazardous Waste Code Following Equipment Cleaning and Replacement. Wastes from wood preserving processes at plants that do not resume or initiate use of chlorophenolic preservatives will not meet the listing definition of F032 in §A of this regulation once the generator has met all of the requirements of §C(3) of this regulation. The waste in §C(1) of this regulation, however, may still be regulated as hazardous waste for other reasons under the provisions of this chapter. A generator who seeks to have the F032 waste code deleted from a waste shall: Clean or replace all process equipment that may have come into contact with chlorophenolic formulations or their constituents, including, but not limited to: Treatment cylinders, Sumps, Tanks, Piping systems, Drip pads, Fork lifts, and Trams; Clean or replace all process equipment described in §C(3)(a) of this regulation in a manner that minimizes or eliminates the release of hazardous waste, hazardous waste constituents or decomposition products, leachate, or contaminated drippage to the ground water, surface water, or atmosphere; Do one of the following: Prepare, sign, and follow an equipment cleaning plan that meets the requirements of §C(3)(d) of this regulation and clean equipment in accordance with this section, Prepare, sign, and follow an equipment replacement plan that meets the requirements of §C(3)(h) of this regulation and replace equipment in accordance with this section, or Document that equipment cleaning and replacement carried out after the termination of use of chlorophenolic preservatives, and before June 6, 1991, was performed in accordance with the requirements of this section; Ensure that an equipment cleaning plan prepared under §C(3)(c) of this regulation describes: What equipment will be cleaned, How equipment will be cleaned, What solvent will be used in cleaning, How solvent rinses will be tested, and How cleaning residues will be disposed; Ensure that cleaning performed under §C(3)(c) of this regulation complies with the following requirements: All visible residues are removed from equipment, and Equipment is rinsed with an appropriate solvent until dioxins and dibenzofurans are not detected in the final solvent rinse; Ensure that the following analytical requirements are met: Rinses are tested in accordance with SW-846, Method 8290, which is incorporated by reference in COMAR 26.13.01.05A(4), and If a result is characterized as “not detected”, it is at or below the lower method calibration limit (MCL) in SW-846, Method 8290, Table 1, which is incorporated by reference in COMAR 26.13.01.05A(4); Manage all residues from the cleaning process as F032 wastes; Ensure that an equipment replacement plan prepared under §C(3)(c) of this regulation describes: What equipment will be replaced, How equipment will be replaced, and How equipment will be disposed; Manage as F032 wastes equipment that is discarded as a result of compliance with §C(3)(c) of this regulation; Document that previous equipment cleaning and replacement was performed in accordance with this section and occurred after the cessation of use of chlorophenolic preservatives; and Maintain the following records documenting the equipment cleaning and replacement as part of the facility's operating record: The name and address of the facility, A list of formulations previously used and the date on which their use was terminated in each process at the plant, A list of formulations currently used in each process at the plant, The equipment cleaning or replacement plan, The name and address of the persons who conducted the equipment cleaning and replacement, The dates on which equipment cleaning and replacement were accomplished, The dates of sampling and testing, A description of the sample handling and preparation techniques, including techniques used for extraction, containerization, preservation, and chain-of-custody of the samples, A description of the tests performed, the dates the tests were performed, and the results of the tests, The names and model numbers of instruments used in performing the tests, Quality assurance/quality control (QA/QC) documentation, and The following statement signed by the generator or his authorized representative: “I certify under penalty of law that all process equipment required to be cleaned or replaced under COMAR 26.13.02.16C was cleaned or replaced as represented in the equipment cleaning and replacement plan and accompanying documentation.
