(a) This part identifies those solid wastes which are subject to regulation as hazardous wastes under Parts 262 through 268 and Part 100 and which are subject to the notification requirements of Part

1. 99. In this part:
   1. (1) Subpart A defines the terms "solid waste" and "hazardous waste," identifies those wastes which are excluded from regulation under Parts 262 through 268, 99 and Part 100 of these regulations and establishes special management requirements for hazardous waste produced by very small quantity generators and hazardous waste which is recycled.
      1. (2) Subpart B sets forth the criteria used by the Department to identify characteristics of hazardous waste and to list particular hazardous wastes.
         1. (3) Subpart C identifies characteristics of hazardous waste.
         2. (4) Subpart D lists particular hazardous wastes.

(b) (1) The definition of solid waste contained in this Part applies only to wastes that also are hazardous. For example, it does not apply to materials (such as non-hazardous scrap, paper, textiles, or rubber) that are not otherwise hazardous wastes and that are recycled.

1. (2) This Part identifies only some of the materials which are solid wastes and hazardous wastes under Sections 3007, 3013, and 7003 of RCRA. A material which is not identified or listed in this Part, is still a solid waste and a hazardous waste for purposes of these sections if:
   1. (i) In the case of Sections 3007 and 3013, EPA has reason to believe that the material may be a solid waste within the meaning of Section 1004(27) of RCRA and a hazardous waste within the meaning of Section 1004(5) of RCRA; or (ii) In the case of Section 7003, the statutory elements are established.

(c) An attached statement of basis and purpose for these regulations has been adopted by the Board of Health and is hereby incorporated by reference in these regulations pursuant to C.R.S. 1973, 24-4-103.

(d) For the purposes of §§ 261.2 and 261.6:

1. (1) A “spent material” is 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;
   1. (2) “Sludge” has the same meaning used in § 260.10 of these regulations;
      1. (3) A “by-product” is 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. Examples are process residues such as slags or distillation column bottoms. The term does not include a co-product that is produced for the general public’s use and is ordinarily used in the form it is produced by the process.
         1. (4) A material is “reclaimed” if it is processed to recover a usable product, or if it is regenerated. Examples are recovery of lead values from spent batteries and regeneration of spent solvents.
         2. (5) A material is “used or reused” if it is either:
         3. (i) Employed as an ingredient (including use as an intermediate) in an industrial process to make a product (for example, distillation bottoms from one process used as feedstock in another process). However, a material will 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 (ii) Employed in a particular function or application as an effective substitute for a commercial product (for example, spent pickle liquor used as phosphorous precipitant and sludge conditioner in wastewater treatment).
         4. (6) “Scrap metal” is bits and pieces of metal parts (e.g., bars, turnings, rods, sheets, wire) or metal pieces that may be combined together with bolts or soldering (e.g., radiators, scrap automobiles, railroad box cars), which when worn or superfluous can be recycled.
         5. (7) A material is “recycled” if it is used, reused, or reclaimed.
         6. (8) A material is “accumulated speculatively” if it is accumulated before recycled. A material is not accumulated speculatively, however, if the person accumulating it can show that the material is potentially recyclable and has a feasible means of being recycled; and that–during the calendar year (commencing on January 1)–the amount of material that is recycled, or transferred to a different site for recycling, equals at least 75% by weight or volume of the amount of that material accumulated at the beginning of the period. Materials must be placed in a storage unit with a label indicating the first date that the material began to be accumulated. If placing a label on the storage unit is not practicable, the accumulation period must be documented through an inventory log or other appropriate method. In calculating the percentage of turnover, the 75% requirement is to be applied to each material of the same type (e.g., slags from a single smelting process) that is recycled in the same way (i.e., from which the same material is recovered or that is used in the same way). Materials accumulating in units that would be exempt from regulation under § 261.4(c) are not to be included in making the calculation. Materials that are already defined as solid wastes also are not to be included in making the calculation. Materials are no longer in this category once they are removed from accumulation for recycling, however.
         7. (9) “Excluded scrap metal” is processed scrap metal, unprocessed home scrap metal, and unprocessed prompt scrap metal.
         8. (10) “Processed scrap metal” is 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 (i.e., sorted), and, fines, drosses and related materials which have been agglomerated.

            (Note: shredded circuit boards being sent for recycling are not considered processed scrap metal. They are covered under the exclusion from the definition of solid waste for shredded circuit boards being recycled (§ 261.4(a)(15)).

         9. (11) “Home scrap metal” is scrap metal as generated by steel mills, foundries, and refineries such as turnings, cuttings, punchings, and borings.
         10. (12) “Prompt scrap metal” is scrap metal as generated by the metal working/fabrication industries and includes such scrap metal as turnings, cuttings, punchings, and borings. Prompt scrap is also known as industrial or new scrap metal. § 261.2 Definition of solid waste.

(a) (1) A solid waste is any discarded material that is not excluded by d§ 261.4(a) or that is not excluded by variance granted under § 260.30 and § 260.31.

1. (2) A discarded material is any material which is:
   1. (i) Abandoned, as explained in paragraph (b) of this section; or (ii) Recycled, as explained in paragraph (c) of this section; or (iii) Considered inherently waste-like, as explained in paragraph (d) of this section.

(b) Materials are solid waste if they are abandoned by being:

1. (1) Disposed of; or (2) Burned or incinerated; or (3) Accumulated, stored, or treated (but not recycled) before or in lieu of being abandoned by being disposed of, burned, or incinerated; or (4) Sham recycled, as explained in paragraph (g) of this section.

(c) Materials are solid wastes if they are recycled or accumulated, stored, or treated before recycling as specified in paragraphs (c)(1) through (c)(4) of this section.

1. (1) Used in a manner constituting disposal.
   1. (i) Materials noted with a “*” in column 1 of Table I are solid waste when they are:
      1. (A) Applied to or placed on the land in a manner that constitutes disposal; or (B) Used to produce products that are applied to or placed on the land or are otherwise contained in products that are applied to or placed on the land (in which cases the product itself remains a solid waste).
         1. (ii) However, commercial chemical products listed in § 261.33 are not solid wastes if they are applied to the land and that is their ordinary manner of use.
         2. (2) Burning for energy recovery.
         3. (i) Materials noted with a “*” in column 2 of Table 1 are solid wastes when they are:
         4. (A) Burned to recover energy;
         5. (B) Used to produce a fuel or are otherwise contained in fuels (in which cases the fuel itself remains a solid waste).
         6. (ii) However, commercial chemical products listed in § 261.33 are not solid wastes if they are themselves fuels.
         7. (3) Reclaimed. Materials noted with a “---” in column 3 of Table 1 are not solid wastes when reclaimed. Materials noted with a “*” in column 3 of Table 1 are solid wastes when reclaimed unless they meet the requirements of § 261.4(a)(17).
         8. (4) Accumulated speculatively. Materials noted with a “*” in column 4 of Table 1 are solid wastes when accumulated speculatively.

Note: The terms “spent materials”, “sludges”, “by-products”, “scrap metal”, and “processed scrap metal” are defined in ‘ 261.1.

(d) Inherently waste-like materials. The following materials are solid wastes when they are recycled in any manner:

1. (1) Hazardous Waste Nos. F020, F021 (unless used as an ingredient to make a product at the site of generation), F022, F023, F026, and F028.
   1. (2) Secondary materials fed to a halogen acid furnace that exhibit a characteristic of a hazardous waste or are listed as a hazardous waste as defined in Subparts C or D of this part, except for brominated material that meets the following criteria:
      1. (i) The material must contain a bromine concentration of at least 45%; and (ii) The material must contain less than a total of 1% of toxic organic compounds listed in Appendix VIII; and (iii) The material is processed continually on-site in the halogen acid furnace via direct conveyance (hard piping).
         1. (3) The Department will use the following criteria to add wastes to that list:
         2. (i) (A) The materials are ordinarily disposed of, burned, or incinerated; or (B) The materials contain toxic constituents listed in Appendix VIII of Part 261 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; and (ii) The material may pose a substantial hazard to human health and the environment when recycled.

(e) Materials that are not solid waste when recycled.

1. (1) Materials are not solid wastes when they can be shown to be recycled by being:
   1. (i) Used or reused as ingredients in an industrial process to make a product, provided the materials are not being reclaimed; or (ii) Used or reused as effective substitutes for commercial products; or (iii) Returned to the original process from which they are generated, without first being reclaimed or land disposed. The material must be returned as a substitute for feedstock materials. In cases where the original process to which the material is returned is a secondary process, the materials must be managed such that there is no placement on the land. In cases where the materials are generated and reclaimed within the primary mineral processing industry, the conditions of the exclusion found at § 261.4(a)(17) apply rather than this paragraph.
      1. (2) The following materials are solid wastes, even if the recycling involves use, reuse, or return to the original process (described in paragraphs (e)(1)(i) through (iii) of this section:
         1. (i) Materials used in a manner constituting disposal, or used to produce products that are applied to the land; or (ii) Materials burned for energy recovery, used to produce a fuel, or contained in fuels; or (iii) Materials accumulated speculatively; or (iv) Materials listed in paragraphs (d)(1) and (d)(2) of this section.

(f) (1) Documentation of claims that materials are not solid wastes or are conditionally exempt from regulation. In order to claim that a certain material is not a solid waste or is conditionally exempt from regulation, owners or operators must demonstrate that there is a known market or disposition for the material, and that they meet the terms of the exclusion or exemption. In doing so, they must 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, owners or operators of facilities claiming that they actually are recycling materials must show that they have the necessary equipment to do so. Materials that are not legitimately recycled are discarded and are solid waste. In determining whether their recycling is legitimate, owners or operators must address the requirements below.

1. (2) Reserved.

(g) Sham recycling. A hazardous secondary material found to be sham recycled is considered discarded and a solid waste. Sham recycling is recycling that is not legitimate recycling as defined in § 260.43.

§ 261.3 Definition of hazardous waste.

(a) A solid waste, as defined in § 261.2, is a hazardous waste if it has no commercial use or value and:

1. (1) It is not excluded from regulation as a hazardous waste under § 261.4(b); and (2) It meets any of the following criteria:
   1. (i) It exhibits any of the characteristics of hazardous waste identified in Subpart C of this part. However, any mixture of a waste from the extraction, beneficiation, and processing of ores and minerals excluded under § 261.4(b)(7) and any other solid waste exhibiting a characteristic of hazardous waste under Subpart C is a hazardous waste only if it exhibits a characteristic that would not have been exhibited by the excluded waste alone if such mixture had not occurred, or if it continues to exhibit any of the characteristics exhibited by the non-excluded wastes prior to mixture. Further, for the purposes of applying the Toxicity Characteristic to such mixtures, the mixture is also a hazardous waste if it exceeds the maximum concentration for any contaminant listed in table I to §
      1. 261.24 that would not have been exceeded by the excluded waste alone if the
         1. mixture had not occurred or if it continues to exceed the maximum concentration for any contaminant exceeded by the nonexempt waste prior to mixture.
         2. (ii) It is listed in Subpart D and has not been excluded from the lists in Subpart D under § §260.20 and 260.22.
         3. (iii) Reserved (iv) It is a mixture of solid waste and one or more hazardous wastes listed in Subpart D and has not been excluded from paragraph (a)(2) of this section under § §
         4. 260.20 and 260.22, or paragraph (g) of this section; however, the following

            mixtures of solid wastes and hazardous wastes listed in Subpart D of this part are not hazardous wastes (except by application of paragraph (a)(2)(i) or (ii) of this section) if the generator can demonstrate that the mixture consists of wastewater the discharge of which is subject to regulation under either Section 402 or Section 307(b) of the Clean Water Act (including wastewater at facilities which have eliminated the discharge of wastewater) and:

         5. (A) One or more of the following spent solvents listed in § 261.31 - carbon tetrachloride, tetrachloroethylene, trichloroethylene – provided that the maximum total weekly usage of these solvents (other than the amounts that can be demonstrated not to be discharged to wastewater) divided by the average weekly flow of wastewater into the headworks of the facility’s wastewater treatment or pre-treatment system does not exceed 1 part per million; or (B) One or more of the following spent solvents listed in § 261.31 - methylene chloride, 1,1,1-trichloroethane, chlorobenzene, o- dichlorobenzene, cresols, cresylic acid, nitrobenzene, toluene, methyl ethyl ketone, carbon disulfide, isobutanol, pyridine, spent chlorofluorocarbon solvents - provided that the maximum total weekly usage of these solvents (other than the amounts that can be demonstrated not to be discharged to wastewater) divided by the average weekly flow of wastewater into the headworks of the facility’s wastewater treatment or pre-treatment system does not exceed 25 parts per million; or (C) One of the following wastes listed in § 261.32, provided that the wastes are discharged to the refinery oil recovery sewer before primary oil/water/solids separation - heat exchanger bundle cleaning sludge from the petroleum refining industry (EPA Hazardous Waste No. K050), crude oil storage tank sediment from petroleum refining operations (EPA Hazardous Waste No. K169), clarified slurry oil tank sediment and/or in- line filter/separation solids from petroleum refining operations (EPA Hazardous Waste No. K170), spent hydrotreating catalyst (EPA Hazardous Waste No. K171), and spent hydrorefining catalyst (EPA Hazardous Waste No. K172); or (D) A discarded commercial chemical product, or chemical intermediate listed in § 261.33, arising from de minimis losses of these materials from manufacturing operations in which these materials are used as raw materials or are produced in the manufacturing process. For purposes of this sub-paragraph, “de minimis losses include those from normal material handling operations (e.g. spills from the unloading or transfer of materials from bins or other containers, leaks from pipes, valves or other devices used to transfer materials); minor leaks of process equipment; storage tanks or containers; leaks from well maintained pump packings and seals; sample purgings; relief device discharges; discharges from safety showers and rinsing and cleaning of personal safety equipment; and rinsate from empty containers or from containers that are rendered empty by that rinsing; or (E) Wastewater resulting from laboratory operations containing toxic (T) wastes listed in Subpart D, provided that the annualized average flow of laboratory wastewater does not exceed one percent of total wastewater flow into the headworks of the facility’s wastewater treatment or pre- treatment system, or provided the wastes, combined annualized average concentration does not exceed one part per million in the headworks of the facility’s wastewater treatment or pretreatment facility. Toxic (T) wastes used in laboratories that are demonstrated not to be discharged to wastewater are not to be included in this calculation; or (F) One or more of the following wastes listed in § 261.32 -- wastewaters from the production of carbamates and carbamoyl oximes (EPA Hazardous Waste No. K157)--Provided that the maximum weekly usage of formaldehyde, methyl chloride, methylene chloride, and triethylamine (including all amounts that can not be demonstrated to be reacted in the process, destroyed through treatment, or is recovered, i.e., what is discharged or volatilized) divided by the average weekly flow of process wastewater prior to any dilutions into the headworks of the facility’s wastewater treatment system does not exceed a total of 5 parts per million by weight; or (G) Wastewaters derived from the treatment of one or more of the following wastes listed in § 261.32 -- organic waste (including heavy ends, still bottoms, light ends, spent solvents, filtrates, and decantates) from the production of carbamates and carbamoyl oximes (EPA Hazardous Waste No. K156)--Provided, that the maximum concentration of formaldehyde, methyl chloride, methylene chloride, and triethylamine prior to any dilutions into the headworks of the facility’s wastewater treatment system does not exceed a total of 5 milligrams per liter.
         6. (v) Rebuttable presumption for used oil. Used oil containing more than 1000 ppm total halogens is presumed to be a hazardous waste because it has been mixed with halogenated hazardous waste listed in Subpart D of Part 261 of these regulations. Persons may rebut this presumption by demonstrating that the used oil does not contain hazardous waste (for example, by showing that the used oil does not contain significant concentrations of halogenated hazardous constituents listed in Appendix VIII of Part 261 of these regulations).
         7. (A) The rebuttable presumption does not apply to metalworking oils/fluids containing chlorinated paraffins, if they are processed, through a tolling agreement, to reclaim metalworking oils/fluids. The presumption does apply to metalworking oils/fluids if such oils/fluids are recycled in any other manner, or disposed.
         8. (B) The rebuttable presumption does not apply to used oils contaminated with chlorofluorocarbons (CFCs) removed from refrigeration units where the CFCs are destined for reclamation. The rebuttable presumption does apply to used oils contaminated with CFCs that have been mixed with used oil from sources other than refrigeration units.

(b) A solid waste which is not excluded from regulation under paragraph (a)(1) of this section becomes a hazardous waste when any of the following events occur:

1. (1) In the case of a waste listed in Subpart D, when the waste first meets the listing description set forth in Subpart D.
   1. (2) In the case of a mixture of solid waste and one or more listed hazardous wastes, when a hazardous waste listed in Subpart D is first added to the solid waste.
      1. (3) In the case of any other waste (including a waste mixture), when the waste exhibits any of the characteristics identified in Subpart C.

(c) Unless and until it meets the criteria of paragraph (d):

1. (1) A hazardous waste will remain a hazardous waste.
   1. (2) (i) Except as otherwise provided in paragraph (c)(2)(ii) or (g) of this section, 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 run-off) is a hazardous waste. (However, materials that are reclaimed from solid wastes and that are used beneficially are not solid wastes and hence are not hazardous wastes under this provision unless the reclaimed material is burned for energy recovery or used in a manner constituting disposal).
      1. (ii) The following solid wastes are not hazardous even though they are generated from the treatment, storage, or disposal of a hazardous waste, unless they exhibit one or more of the characteristics of hazardous waste:
         1. (A) Waste pickle liquor sludge generated by lime stabilization of spent pickle liquor from the iron and steel industry (SIC Codes 331 and 332) (B) Wastes from burning any of the materials exempted from regulation by § 261.6(a)(3)(iii)and(iv).
         2. (C) (1) Nonwastewater residues, such as slag, resulting from high temperature metals recovery (HTMR) processing of K061, K062, or F006 waste, in units identified as rotary kilns, flame reactors, electric furnaces, plasma arc furnaces, slag reactors, rotary hearth furnace/electric furnace combinations or industrial furnaces (as defined in § 260.10), that are disposed in subtitle D units, provided that these residues meet the generic exclusion levels identified in the tables in this paragraph, for all constituents, and exhibit no characteristics of hazardous waste. Testing requirements must be incorporated in a facility’s waste analysis plan or a generator’s self-implementing waste analysis plan; at a minimum, composite samples of residues must be collected and analyzed quarterly and/or when the process or operation generating the waste changes. Persons claiming this exclusion will have the burden of proof that the material meets all of the exclusion requirements.

Constituent Maximum for any single composite sample (mg/l) Generic exclusion levels for K061 and K062 nonwastewater HTMR residues Antimony 0.10 Arsenic 0.50 Barium 7.6 Beryllium 0.010 Cadmium 0.050 Chromium (total) 0.33 Lead 0.15 Mercury 0.009 Nickel 1.0 Selenium 0.16 Silver 0.30 Thallium 0.020 Zinc 70 Generic exclusion levels for F006 nonwastewater HTMR residues Antimony 0.10 Arsenic 0.50 Barium 7.6 Beryllium 0.010 Cadmium 0.050 Chromium (total) 0.33 Cyanide (total)(mg/kg) 1.8 Lead 0.15 Mercury 0.009 Nickel 1.0 Selenium 0.16 Silver 0.30 Thallium 0.020 Zinc 70

1. (2) A one-time notification and certification must be placed in the facility’s files and sent to the Department for K061, K062, or F006 HTMR residues that meet the generic exclusion levels for all constituents and do not exhibit any characteristics that are sent to subtitle D units. The notification and certification that is placed in the generator’s or treater’s files must be updated if the process or operation generating the waste changes and/or if the subtitle D unit receiving the waste changes. However, the generator or treater need only notify the Department on an annual basis if such changes occur. Such notification and certification should be sent to the Department by the end of the calendar year, but no later than December 31. The notification must include the following information: The name and address of the subtitle D unit receiving the waste shipments; the EPA Hazardous Waste Number(s) and treatability group(s) at the initial point of generation; and, the treatment standards applicable to the waste at the initial point of generation. The certification must be signed by an authorized representative and must state as follows: “I certify under penalty of law that the generic exclusion levels for all constituents have been met without impermissible dilution and that no characteristic of hazardous waste is exhibited. I am aware that there are significant penalties for submitting a false certification, including the possibility of fine and imprisonment.”
   1. (D) Biological treatment sludge from the treatment of one of the following wastes listed in § 261.32 - organic waste (including heavy ends, still bottoms, light ends, spent solvents, filtrates, and decantates) from the production of carbamates and carbamoyl oximes (EPA Hazardous Waste No. K156), and wastewaters from the production of carbamates and carbamoyl oximes (EPA Hazardous Waste No. K157).
      1. (E) Catalyst inert support media separated from one of the following wastes listed in § 261.32 - Spent hydrotreating catalyst (EPA Hazardous Waste No. K171), and Spent hydrorefining catalyst (EPA Hazardous Waste No. K172).

(d) Any solid waste described in paragraph (c) of this section is not a hazardous waste if it meets the following criteria:

1. (1) In the case of any solid waste, it does not exhibit any of the characteristics of hazardous waste identified in Subpart C of this part. (However, wastes that exhibit a characteristic at the point of generation may still be subject to the requirements of Part 268, even if they no longer exhibit a characteristic at the point of land disposal.) (2) In the case of a waste which is a listed waste under Subpart D, contains a waste listed under Subpart D or is derived from a waste listed in Subpart D, it also has been excluded from paragraph (c) under § § 260.20 and 260.22.

(e) Any material which would be a hazardous waste subject to the provisions of these regulations except for the fact that it has commercial use or value is subject to regulations pursuant to §

1. 261.6 of these regulations.

(f) Notwithstanding paragraphs (a) through (d) of this section and provided the debris as defined in Part 268 of these regulations does not exhibit a characteristic identified at Subpart C of this part, the following materials are not subject to regulation under Parts 260, 261 to 267, 268, or 100:

1. (1) Hazardous debris as defined in Part 268 of these regulations that has been treated using one of the required extraction or destruction technologies specified in Table 1 of § 268.45 of these regulations; persons claiming this exclusion in an enforcement action will have the burden of proving by clear and convincing evidence that the material meets all of the exclusion requirements; or (2) Debris as defined in Part 268 of these regulations that the Director, considering the extent of contamination, has determined is no longer contaminated with hazardous waste.

(g) (1) A hazardous waste that is listed in Subpart D of this part solely because it exhibits one or more characteristics of ignitability as defined under § 261.21, corrosivity as defined under § 261.22, or reactivity as defined under § 261.23 is not a hazardous waste, if the waste no longer exhibits any characteristic of hazardous waste identified in Subpart C of this part.

1. (2) The exclusion described in paragraph (g)(1) of this section also pertains to:
   1. (i) Any mixture of a solid waste and a hazardous waste listed in Subpart D of this part solely because it exhibits the characteristics of ignitability, corrosivity, or reactivity as regulated under paragraph (a)(2)(iv) of this section; and (ii) Any solid waste generated from treating, storing, or disposing of a hazardous waste listed in Subpart D of this part solely because it exhibits the characteristics of ignitability, corrosivity, or reactivity as regulated under paragraph (c)(2)(i) of this section.

K060, K087, K141, K142, K143, K144, K145, K147, and K148, and any wastes from the coke by-products processes that are hazardous only because they exhibit the Toxicity Characteristic (TC) specified in § 261.24 of this part, when, subsequent to generation, these materials are recycled to coke ovens, to the tar recovery process as a feedstock to produce coal tar, or mixed with coal tar prior to the sale or refining of the tar. This exclusion is conditioned on there being no land disposal of the wastes from the point at which they are generated to the point at which they are recycled to coke ovens or tar recovery or refining processes, or mixed with coal tar.
         17. (12) Nonwastewater splash condenser dross residue from the treatment of K061 in high temperature metals recovery units, provided it is shipped in drums (if shipped) and not land disposed before recovery.
         18. (13) (i) Oil-bearing hazardous secondary materials (i.e., sludges, byproducts, or spent materials) that are generated at a petroleum refinery (SIC code 2911) and are inserted into the petroleum refining process (SIC code 2911-including, but not limited to, distillation, catalytic cracking, fractionation, or thermal cracking units (i.e., cokers)) unless the material is placed on the land, or speculatively accumulated before being so recycled. Materials inserted into thermal cracking units are excluded under this paragraph, provided that the coke product also does not exhibit a characteristic of hazardous waste. Oil-bearing hazardous secondary materials may be inserted into the same petroleum refinery where they are generated, or sent directly to another petroleum refinery, and still be excluded under this provision. Except as provided in paragraph (a)(13)(ii) of this section, oil-bearing hazardous secondary materials generated elsewhere in the petroleum industry (i.e., from sources other than petroleum refineries) are not excluded under this section. Residuals generated from processing or recycling materials excluded under this paragraph (a)(13)(i), where such materials as generated would have otherwise met a listing under Subpart D of this part, are designated as F037 listed wastes when disposed of or intended for disposal.
         19. (ii) Recovered oil that is recycled in the same manner and with the same conditions as described in paragraph (a)(13)(i) of this section. Recovered oil is oil that has been reclaimed from secondary materials (including wastewater) generated from normal petroleum industry practices, including refining, exploration and production, bulk storage, and transportation incident thereto (SIC codes 1311, 1321, 1381, 1382, 1389, 2911, 4612, 4613, 4922, 4923, 4789, 5171, and 5172.) Recovered oil does not include oil-bearing hazardous wastes listed in Subpart D of this part; however, oil recovered from such wastes may be considered recovered oil. Recovered oil does not include used oil as defined in § 279.1 of these regulations.
         20. (14) Excluded scrap metal (processed scrap metal, unprocessed home scrap metal, and unprocessed prompt scrap metal) being recycled.
         21. (15) Shredded circuit boards being recycled provided that they are:

         23. (16) Reserved (17) Spent materials (as defined in § 261.1) (other than hazardous wastes listed in Subpart D of this part) generated within the primary mineral processing industry from which minerals, acids, cyanide, water or other values are recovered by mineral processing or by beneficiation, provided that:
         24. (i) The spent material is legitimately recycled to recover minerals, acids, cyanide, water or other values;
         25. (ii) The spent material is not accumulated speculatively;
         26. (iii) Except as provided in paragraph (a)(17)(iv) of this section, the spent material is stored in tanks, containers, or buildings meeting the following minimum integrity standards: a building must be an engineered structure with a floor, walls, and a roof all of which are made of non-earthen materials providing structural support (except smelter buildings may have partially earthen floors provided the spent material is stored on the non-earthen portion), and have a roof suitable for diverting rainwater away from the foundation; a tank must be free standing, not be a surface impoundment (as defined in § 260.10 of these regulations), and be manufactured of a material suitable for containment of its contents; a container must be free standing and be manufactured of a material suitable for containment of its contents. If tanks or containers contain any particulate which may be subject to wind dispersal, the owner/operator must operate these units in a manner which controls fugitive dust. Tanks, containers, and buildings must be designed, constructed and operated to prevent significant releases to the environment of these materials.
         27. (iv) The Regional Administrator or the State Director may make a site-specific determination, after public review and comment, that only solid mineral processing spent material may be placed on pads, rather than in tanks, containers, or buildings. Solid mineral processing spent materials do not contain any free liquid. The decision-maker must affirm that pads are designed, constructed and operated to prevent significant releases of the spent material into the environment. Pads must provide the same degree of containment afforded by the non-RCRA tanks, containers and buildings eligible for exclusion.
         28. (A) The decision-maker must also consider if storage on pads poses the potential for significant releases via groundwater, surface water, and air exposure pathways. Factors to be considered for assessing the groundwater, surface water, air exposure pathways are: the volume and physical and chemical properties of the spent material, including its potential for migration off the pad; the potential for human or environmental exposure to hazardous constituents migrating from the pad via each exposure pathway, and the possibility and extent of harm to human and environmental receptors via each exposure pathway.
         29. (B) Pads must meet the following minimum standards: be designed of non- earthen material that is compatible with the chemical nature of the mineral processing spent material, capable of withstanding physical stresses associated with placement and removal, have run on/runoff controls, be operated in a manner which controls fugitive dust, and have integrity assurance through inspections and maintenance programs.
         30. (C) Before making a determination under this paragraph, the Regional Administrator or State Director must provide notice and the opportunity for comment to all persons potentially interested in the determination. This can be accomplished by placing notice of this action in major local newspapers, or broadcasting notice over local radio stations.
         31. (v) The owner or operator provides notice to the Regional Administrator or State Director, providing the following information: the types of materials to be recycled; the type and location of the storage units and recycling processes; and the annual quantities expected to be placed in land-based units. This notification must be updated when there is a change in the type of materials recycled or the location of the recycling process.
         32. (vi) For purposes of § 261.4(b)(7) of this section, mineral processing spent material must be the result of mineral processing and may not include any listed hazardous wastes. Listed hazardous wastes and characteristic hazardous wastes generated by non-mineral processing industries are not eligible for the conditional exclusion from the definition of solid waste.
         33. (18) Petrochemical recovered oil from an associated organic chemical manufacturing facility, where the oil is to be inserted into the petroleum refining process (SIC code 2911) along with normal petroleum refinery process streams, provided:
         34. (i) The oil is hazardous only because it exhibits the characteristic of ignitability (as defined in § 261.21) and/or toxicity for benzene (§ 261.24, waste code D018); and (ii) The oil generated by the organic chemical manufacturing facility is not placed on the land, or speculatively accumulated before being recycled into the petroleum refining process. An “associated organic chemical manufacturing facility” is a facility where the primary SIC code is 2869, but where operations may also include SIC codes 2821,2822, and 2865; and is physically co-located with a petroleum refinery; and where the petroleum refinery to which the oil being recycled is returned also provides hydrocarbon feedstocks to the organic chemical manufacturing facility. “Petrochemical recovered oil” is oil that has been reclaimed from secondary materials (i.e., sludges, byproducts, or spent materials, including wastewater) from normal organic chemical manufacturing operations, as well as oil recovered from organic chemical manufacturing processes.
         35. (19) Spent caustic solutions from petroleum refining liquid treating processes used as a feedstock to produce cresylic or naphthenic acid unless the material is placed on the land, or accumulated speculatively as defined in § 261.1(c).

(D) Submit to the Regional Administrator or State Director an annual report that identifies the total quantities of all excluded hazardous secondary materials that were used to manufacture zinc fertilizers or zinc fertilizer ingredients in the previous year, the name and address of each generating facility, and the industrial process(s) from which they were generated.
         51. (iv) Nothing in this section preempts, overrides or otherwise negates the provision in § 262.11 of these regulations, which requires any person who generates a solid waste to determine if that waste is a hazardous waste.
         52. (v) Interim status and permitted storage units that have been used to store only zinc- bearing hazardous wastes prior to the submission of the one-time notice described in paragraph (a)(20)(ii)(A) of this section, and that afterward will be used only to store hazardous secondary materials excluded under this paragraph, are not subject to the closure requirements of Parts 264 and 265 of these regulations.
         53. (21) Zinc fertilizers made from hazardous wastes, or hazardous secondary materials that are excluded under paragraph (a)(20) of this section, provided that:
         54. (i) The fertilizers meet the following contaminant limits:
         55. (A) For metal contaminants:

(d) Procedures for demonstrating that dyes and/or pigment nonwastewaters are not K181. The procedures described in paragraphs (d)(1)-(d)(3) and (d)(5) of this section establish when nonwastewaters from the production of dyes/pigments would not be hazardous (these procedures apply to wastes that are not disposed in landfill units or treated in combustion units as specified in paragraph (a) of this section). If the nonwastewaters are disposed in landfill units or treated in combustion units as described in paragraph (a) of this section, then the nonwastewaters are not hazardous. In order to demonstrate that it is meeting the landfill disposal or combustion conditions contained in the K181 listing description, the generator must maintain documentation as described in paragraph (d)(4) of this section.

1. (1) Determination based on no K181 constituents. Generators that have knowledge (e.g., knowledge of constituents in wastes based on prior sampling and analysis data and/or information about raw materials used, production processes used, and reaction and degradation products formed) that their wastes contain none of the K181 constituents (see paragraph (c) of this section) can use their knowledge to determine that their waste is not K181. The generator must document the basis for all such determinations on an annual basis and keep each annual documentation for three years.
   1. (2) Determination for generated quantities of 1,000 MT/yr or less for wastes that contain K181 constituents. If the total annual quantity of dyes and/or pigment nonwastewaters generated is 1,000 metric tons or less, the generator can use knowledge of the wastes (e.g., knowledge of constituents in wastes based on prior analytical data and/or information about raw materials used, production processes used, and reaction and degradation products formed) to conclude that annual mass loadings for the K181 constituents are below the listing levels of paragraph (c) of this section. To make this determination, the generator must:
      1. (i) Each year document the basis for determining that the annual quantity of nonwastewaters expected to be generated will be less than 1,000 metric tons.
         1. (ii) Track the actual quantity of nonwastewaters generated from January 1 through December 31 of each year. If, at any time within the year, the actual waste quantity exceeds 1,000 metric tons, the generator must comply with the requirements of paragraph (d)(3) of this section for the remainder of the year.
         2. (iii) Keep a running total of the K181 constituent mass loadings over the course of the calendar year.
         3. (iv) Keep the following records on site for the three most recent calendar years in which the hazardous waste determinations are made:
         4. (A) The quantity of dyes and/or pigment nonwastewaters generated.
         5. (B) The relevant process information used.
         6. (C) The calculations performed to determine annual total mass loadings for each K181 constituent in the nonwastewaters during the year.
         7. (3) Determination for generated quantities greater than 1,000 MT/yr for wastes that contain K181 constituents. If the total annual quantity of dyes and/or pigment nonwastewaters generated is greater than 1,000 metric tons, the generator must perform all of the steps described in paragraphs ((d)(3)(i)-(d)(3)(xi) of this section) in order to make a determination that its waste is not K181.
         8. (i) Determine which K181 constituents (see paragraph (c) of this section) are reasonably expected to be present in the wastes based on knowledge of the wastes (e.g., based on prior sampling and analysis data and/or information about raw materials used, production processes used, and reaction and degradation products formed).
         9. (ii) If 1,2-phenylenediamine is present in the wastes, the generator can use either knowledge or sampling and analysis procedures to determine the level of this constituent in the wastes. For determinations based on use of knowledge, the generator must comply with the procedures for using knowledge described in paragraph (d)(2) of this section and keep the records described in paragraph (d)(2)(iv) of this section. For determinations based on sampling and analysis, the generator must comply with the sampling and analysis and recordkeeping requirements described below in this section.
         10. (iii) Develop a waste sampling and analysis plan (or modify an existing plan) to collect and analyze representative waste samples for the K181 constituents reasonably expected to be present in the wastes. At a minimum, the plan must include:
         11. (A) A discussion of the number of samples needed to characterize the wastes fully;
         12. (B) The planned sample collection method to obtain representative waste samples;
         13. (C) A discussion of how the sampling plan accounts for potential temporal and spatial variability of the wastes.
         14. (D) A detailed description of the test methods to be used, including sample preparation, clean up (if necessary), and determinative methods.
         15. (iv) Collect and analyze samples in accordance with the waste sampling and analysis plan.
         16. (A) The sampling and analysis must be unbiased, precise, and representative of the wastes.
         17. (B) The analytical measurements must be sufficiently sensitive, accurate and precise to support any claim that the constituent mass loadings are below the listing levels of paragraph (c) of this section.
         18. (v) Record the analytical results.
         19. (vi) Record the waste quantity represented by the sampling and analysis results.
         20. (vii) Calculate constituent-specific mass loadings (product of concentrations and waste quantity).
         21. (viii) Keep a running total of the K181 constituent mass loadings over the course of the calendar year.
         22. (ix) Determine whether the mass of any of the K181 constituents listed in paragraph (c) of this section generated between January 1 and December 31 of any year is below the K181 listing levels.
         23. (x) Keep the following records on site for the three most recent calendar years in which the hazardous waste determinations are made:
         24. (A) The sampling and analysis plan.
         25. (B) The sampling and analysis results (including QA/QC data) (C) The quantity of dyes and/or pigment nonwastewaters generated.
         26. (D) The calculations performed to determine annual mass loadings.
         27. (xi) Nonhazardous waste determinations must be conducted annually to verify that the wastes remain nonhazardous.
         28. (A) The annual testing requirements are suspended after three consecutive successful annual demonstrations that the wastes are nonhazardous. The generator can then use knowledge of the wastes to support subsequent annual determinations.
         29. (B) The annual testing requirements are reinstated if the manufacturing or waste treatment processes generating the wastes are significantly altered, resulting in an increase of the potential for the wastes to exceed the listing levels.
         30. (C) If the annual testing requirements are suspended, the generator must keep records of the process knowledge information used to support a nonhazardous determination. If testing is reinstated, a description of the process change must be retained.
         31. (4) Recordkeeping for the landfill disposal and combustion exemptions. For the purposes of meeting the landfill disposal and combustion condition set out in the K181 listing description, the generator must maintain on site for three years documentation demonstrating that each shipment of waste was received by a landfill unit that is subject to or meets the landfill design standards set out in the listing description, or was treated in combustion units as specified in the listing description.
         32. (5) Waste holding and handling. During the interim period, from the point of generation to completion of the hazardous waste determination, the generator is responsible for storing the wastes appropriately. If the wastes are determined to be hazardous and the generator has not complied with the subtitle C requirements during the interim period, the generator could be subject to an enforcement action for improper management. § 261.33 Discarded commercial chemical products, off specification species, container residues, and spill residues thereof.

The following materials or items are hazardous wastes if and when they are discarded or intended to be discarded as described in § 261.2(a)(2), when they are mixed with waste oil or used oil or other material and applied to the land for dust suppression or road treatment, when they are otherwise applied to the land in lieu of their original intended use or when they are contained in products that are applied to the land in lieu of their original intended use, or when, in lieu of their original intended use, they are produced for use as (or as a component of) a fuel, distributed for use as a fuel, or burned as a fuel, or when they are residues described in § 261.33(d) and are not recycled in accordance with § 261.2(e) within 90 days of the initial spill event.

(a) Any commercial chemical product, or manufacturing chemical intermediate having the generic name listed in paragraphs (e) or (f) of this section.

(b) Any off-specification commercial product or manufacturing chemical intermediate which, if it met specifications, would have the generic name listed in paragraphs (e) or (f) of this section.

(c) Any residue remaining in a container or in an inner liner removed from a container that has held any commercial chemical product or manufacturing chemical intermediate having the generic name listed in paragraph (e) or (f) of this section, unless the container is empty as defined in § 261.7(b) or § 267.507 of these regulations.

1. [Comment: Unless the residue is being beneficially used or reused, or legitimately recycled or reclaimed; or being accumulated, stored, transported or treated prior to such use, re-use, recycling or reclamation, EPA considers the residue to be intended for discard, and thus a hazardous waste. An example of a legitimate re-use of the residue would be where the residue remains in the container and the container is used to hold the same commercial chemical product or manufacturing chemical product or manufacturing chemical intermediate it previously held. An example of the discard of the residue would be where the drum is sent to a drum reconditioner who reconditions the drum but discards the residue.].

(d) 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 commercial chemical product or manufacturing chemical intermediate having the generic name listed in paragraph (a) through (d) of this section, or 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 off-specification chemical product and manufacturing intermediate which, if it met specifications, would have the generic name listed in paragraphs (e) or (f) of this section. Note: Colorado’s regulations are more stringent than the federal regulations of 40 CFR § 261.33(d) with regard to application of P and U-listed waste codes to unused commercial chemical products. Pursuant to the comment at 40 CFR 261.33(d), the listed chemical must be the “sole active ingredient” to meet the listing description. In Colorado, formulations may have more than one active ingredient and still meet the listing description.

(e) The commercial chemical products, manufacturing chemical intermediates or off specification commercial chemical products or manufacturing chemical intermediates referred to in paragraphs

1. (a) through (d) of this section, are identified as acute hazardous wastes (H). [Comment: For the convenience of the regulated community the primary hazardous properties of these materials have been indicated by the letters T (Toxicity), and R (Reactivity). Absence of a letter indicates that the compound only is listed for acute toxicity.] These wastes and their corresponding EPA Hazardous Waste Numbers are: Hazardous Chemical Substance Common Name waste No. abstracts No.

§ 261.35 Deletion of Certain Hazardous Waste Codes Following Equipment Cleaning and Replacement.

(a) 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 once the generator has met all of the requirements of paragraphs (b) and (c) of this section. These wastes may, however, continue to meet another hazardous waste listing description or may exhibit one or more of the hazardous waste characteristics.

(b) Generators must either clean or replace all process equipment that may have come in contact with chlorophenolic formulations or constituents thereof, including, but not limited to: treatment cylinders, sumps, tanks, piping systems, drip pads, fork lifts, and trams in a manner which minimizes or eliminates the escape of hazardous waste or waste constituents, leachate, contaminated drippage, or hazardous waste decomposition products to the ground water, surface water, or atmosphere.

1. (1) Generators shall do one of the following:
   1. (i) Prepare and follow an equipment cleaning plan and clean equipment in accordance with this section;
      1. (ii) Prepare and follow an equipment replacement plan and replace equipment in accordance with this section; or (iii) Document cleaning and replacement in accordance with this section, carried out after termination of use of chlorophenolic preservations.
         1. (2) Cleaning Requirements.
         2. (i) Prepare and sign a written equipment cleaning plan that describes:
         3. (A) The equipment to be cleaned;
         4. (B) How the equipment will be cleaned;
         5. (C) The solvent to be used in cleaning;
         6. (D) How solvent rinses will be tested; and (E) How cleaning residues will be disposed.
         7. (ii) Equipment must be cleaned as follows:
         8. (A) Remove all visible residues from process equipment;
         9. (B) Rinse process equipment with an appropriate solvent until dioxins and dibenzofurans are not detected in the final solvent rinse.
         10. (iii) Analytical requirements.
         11. (A) Rinses must be tested using an appropriate method.
         12. (B) “Not detected” means at or below the following lower method calibration limits (MCLs): The 2,3,7,8-TCDD-based MCL--0.01 parts per trillion (ppt), sample weight of 1000 g, IS spiking level of 1 ppt, final extraction volume of 10-50 µL. For other congeners--multiply the values by 1 for TCDF/PeCDD/PeCDF, by 2.5 for HxCDD/HxCDF/HpCDD/HpCDF, and by 5 for OCDD/OCDF.
         13. (iv) The generator must manage all residues from the cleaning process as F032 waste.
         14. (3) Replacement requirements.
         15. (i) Prepare and sign a written equipment replacement plan that describes:
         16. (A) The equipment to be replaced;
         17. (B) How the equipment will be replaced; and (C) How the equipment will be disposed.
         18. (ii) The generator must manage the discarded equipment as F032 waste.
         19. (4) Documentation requirements.
         20. (i) Document that previous equipment cleaning and/or replacement was performed in accordance with this section and occurred after cessation of use of chlorophenolic preservatives.

(c) The generator must maintain the following records documenting the cleaning and replacement as part of the facilities operating record:

1. (1) The name and address of the facility;
   1. (2) Formulations previously used and the date on which their use ceased in each process at the plant;
      1. (3) Formulations currently used in each process at the plant;
         1. (4) The equipment cleaning or replacement plan;
         2. (5) The name and address of any persons who conducted the cleaning and replacement;

            trichloroethene (TCE)

            “Significant changes” also refers to the appearance of any additional Part 264, Appendix IX hazardous constituents (in either the carbon or the influent) not represented in SACWSD’s October 1990 delisting petition.

f) The Department reserves the right to re-evaluate and, if necessary, revoke this delisting or modify its conditions in the event of any “significant changes” (as defined above) in the carbon or in the influent to SACWSD’s GAC system.

DELISTING #: 002 FACILITY: NTI, A Division of Colorado Springs Circuits, Inc. (“NTI”) ADDRESS: 6035 Galley Road, Colorado Springs, 80915 WASTE: Wastewater Treatment Sludge from Electroplating Operations EPA hazardous waste # F006, generated after August 20, 1996.

The Solid and Hazardous Waste Commission is hereby removing the conditional delisting granted to NTI, a division of Colorado Springs Circuits, Inc. (“NTI”), for its facility located at 6035 Galley Road in Colorado Springs, Colorado (the “Facility”).

NTI was granted a conditional delisting by the Commission on August 20, 1996 for wastewater treatment sludge (F006 hazardous waste) generated from electroplating operations at the Facility. The delisting was granted under conditions that specified sampling, storage, recordkeeping and disposal requirements for the delisted sludge. The conditional delisting of the F006 waste also prohibited any major changes to the electroplating process or wastewater treatment process at the Facility without prior notification, evaluation, and approval by the Division. In January of 2000, Dynamic Details, Inc. (“DDI”), formally known as NTI, announced its plans to consolidate its pre-production manufacturing operations located at the Facility into its Dallas, Texas operation, which would result in the complete closure of the Colorado Springs facility. On June 20, 2000, the Division received formal notice indicating that DDI had officially ceased Operations at the Facility on December 31, 1999, and had completed all closure activities at the Facility as of May 18, 2000. Therefore, NTI’s August 1996 conditional delisting is no longer applicable, and the Commission is removing the delisting.

DELISTING #: 007 FACILITY: Golden Aluminum, Inc.

ADDRESS: 1405 East 14th Street, Fort Lupton, CO 80621 WASTE: Wastewater Treatment Sludge from Aluminum Cleaning and Conversion Coating Operations. EPA Hazardous Waste Code F019 generated after the effective date of this delisting. The Solid and Hazardous Waste Commission is hereby removing the conditional delisting granted to the Golden Aluminum, Inc. (“Golden Aluminum”) facility in Fort Lupton, Colorado (the “Facility”). Golden Aluminum was granted a conditional delisting by the Commission on October 18, 2005 for wastewater treatment sludge (F019 hazardous waste) generated from aluminum cleaning and conversion coating operations at the Facility.

The delisting was granted under conditions that specified disposal, recordkeeping, and storage requirements for the delisted sludge. The conditional delisting of the F019 waste also prohibited any major changes to the chemical conversion coating process or wastewater treatment process without prior notification, evaluation, and approval by the Division. On February 12, 2008, the Division received notification from Golden Aluminum indicating that the Facility would be converting its titanium conversion coating process to a chrome conversion coating process effective February 18, 2008.

Delisting determinations are made on a case-by-case basis with respect to a specific waste generation process. Golden Aluminum’s change to a new chromate conversion coating process using hexavalent chromium is a significant change from the titanium conversion coating process described in the Facility’s April 8, 2005 delisting petition.

Golden Aluminum’s 2005 delisting no longer covers the wastewater treatment sludge generated at the Facility, and the Facility was notified by the Division on March 24, 2008 that wastewater treatment sludge generated from the new chromate conversion coating process at the Facility must be collected and managed as a hazardous waste with the waste code of F019.

e. Disposal Requirements The delisted waste shall be disposed in a landfill meeting the requirements of the Colorado Solid Waste Regulations (6 CCR 1007-2) or recycled at an appropriate metals reclamation facility. Statement of Basis and Purpose Part 261 - Identification and Listing of Hazardous Waste Purpose The fundamental purpose of the Part 261 regulations which are promulgated pursuant to C.R.S. 1973, 25-15-302(2) is to identify those wastes, which, because of the public health and environmental hazards that they may pose in transportation, treatment, storage or disposal, are subject to regulation as hazardous wastes.

Additionally, regulations concerning the identification and listing of hazardous waste are a necessary and required component in conducting a hazardous waste management program; the State intends to obtain EPA authorization for a hazardous waste management program pursuant to C.R.S. 1973, 25-15-302. Such full state authorization to conduct the hazardous waste regulatory program can be granted only upon the determination that the State program is equivalent to that of the EPA. Basis These regulations are based upon a “cradle-to-grave” system of regulation of hazardous waste. Under this system, hazardous waste is tracked and regulated from the point of generation through storage and transportation to the point of treatment and/or disposal. In this manner, a major portion of the hazardous waste generated in the State is regulated and accounted for, thereby minimizing the potential for public health and environmental problems resulting from improper management, handling, transportation and disposal of these wastes. The great potential for public health and environmental problems, including hazards associated with fire, explosion, direct contact, and air, surface water and groundwater contamination resulting from inadequate management of hazardous wastes has been documented at hundreds of sites throughout the nation and has spurred the development of hazardous waste regulations pursuant to the Resource Conservation and Recovery Act (RCRA) of 1976, Public Law 94-580 These regulations are based, for the most part, on those developed by the EPA under Subtitle C of RCRA. This was done for the reasons discussed below. Because the Federal hazardous waste regulations are comprehensive and technically complex, it was felt that adopting the Federal format and amending specific sections to the needs of the State, as opposed to developing State regulations “from scratch”, would save substantial amounts of time and financial resources. Also, it was felt that the process of determination of initial program equivalency would be greatly simplified through adoption of the Federal format. Further, because the Federal regulations are presently subject to frequent amendment, adoption of the Federal format greatly enhances maintaining equivalency of the State regulations to the Federal program.

As stated above, much of the scientific basis for these regulations was developed in the course of EPA research and investigations over a period of several years. Therefore, all information utilized by EPA in developing and proposing these regulations, including that referenced in the Federal Register Volume 45, Number 98, May 19, 1980 p. 33066 et seq. is hereby incorporated in this statement by reference. Pursuant to amendments made to this part 261 effective April 30, 1993, the information contained in the following Federal Registers is incorporated by reference: 55 FR 18726; 56 FR 27300-27330; 55 FR 46354-46397; 56 FR 21955-21960; 55 FR 5340-5342; 55 FR 18496-18506; 54 FR 50968; 53 FR 43881- 43884; 53 FR 43878-43881; and 56 FR 19951.

The basis for these regulations was further developed through a series of twelve public meetings at which comments were received from interested parties. Accordingly, certain changes from the Federal regulations have been incorporated in these regulations where it was deemed advisable as a result of public comment and study of the issues, in order to tailor the regulations more to Colorado’s needs. Such departures from the approach taken in the Federal regulations are discussed in this document under the pertinent topics.

The Regulations These regulations define the terms “solid waste” and “hazardous waste,” and identify those wastes which are excluded from these regulations. This is necessary in order to characterize the universe of materials which are subject to regulation.

Under the definition of hazardous waste, § 261.3, the phrase “if it has no commercial use or value” has been added as a restriction on the EPA definition. The basis for this action was to achieve consistency with the definition of hazardous waste under C.R.S. 1973, 25-15-101(9)(a). Also, under the Exclusions Section — materials which are not solid wastes, the following additions were listed in order to provide consistency with C.R.S. 1973, 25-15-101(9)(a): -inert materials used for construction fill or top soil placement or changing contour for agriculture or mining purposes; -any materials or waste exempted or not regulated as hazardous waste under the Federal Act. Subpart B of these regulations sets forth criteria used to identify characteristics and to list particular hazardous wastes. Since there are hazardous wastes which meet these criteria, but which are not listed under Subpart D nor meet the characteristics under Subpart C, the regulations provide that the Department may identify such a waste as hazardous for purposes of these regulations. This provision is necessary in order to protect public health and the environment by ensuring that all hazardous wastes are adequately managed under these regulations. Hazardous wastes under Subpart C may be subject to regulation based on four characteristics defined in the regulations. These characteristics are ignitability, corrosivity, reactivity and (EP) toxicity. This allows a waste to be characterized as hazardous without specifically listing it by name or waste stream. Additionally, Subpart D lists particular hazardous waste, both by specific industrial process waste streams and as discarded commercial products. The discarded commercial products list is further subdivided into toxic and acutely hazardous wastes. Additionally, these regulations establish special, reduced management requirements for hazardous waste produced by small quantity generators. Small quantity generators are defined as those who generate less than 1,000 kilograms of hazardous waste per month, or less than 1 kilogram of acutely toxic waste within one month. Under this small quantity generator provision, those who treat or dispose of their own waste on-site must have a permit under these regulations or written Departmental approval. This requirement was added by the State in order to clarify the responsibilities of small quantity generators, and to ensure that such activities are conducted in a manner which does not threaten public health or the environment. If hazardous waste is disposed off-site, the waste must be delivered to an interim status or permitted facility, or a state-approved facility.

These regulations also include special requirements for hazardous waste which is used, re-used, recycled or reclaimed. These wastes are subject to reduced regulatory requirements in order to encourage re-use activities. This provision may conflict with C.R.S. 1973, 25-15-101(9)(a) which provides that waste which has commercial use or value is not considered hazardous. EPA is also in the process of revising these re-use regulations and this issue may need to be readdressed in the future. Statement of Basis and Purpose Rule-making Hearing of April 20,1993 Hazardous Waste Management System; Identification and Listing of Hazardous Waste Basis and Purpose.

These amendments to 6 CCR 1007-3, Part 261 are made pursuant to the authority granted to the Hazardous Waste Commission in section 25-15-302(2), C.R.S. Toxicity Characteristic Revisions The Environmental Protection Agency adopted an amendment which exempted from the toxicity characteristic rules certain used chlorofluorocarbon refrigerants which exhibit the toxicity characteristic and which are reclaimed for use. These amendments provide state equivalency with the regulatory requirements of the Environmental Protection Agency.

The amendments also remove the quality assurance requirement found in Method 1311, Toxicity Characteristic Leaching Procedure for correcting measured values for analytical bias. However, this rule retains appropriate quality assurance provisions, including that matrix spike recoveries be calculated and that the method of standard additions be employed as the quantitation method for metallic contaminants when appropriate as specified in the method. These amendments also provide state equivalency with the regulatory requirements of the Environmental Protection Act This Basis and Purpose incorporates by reference the preamble language for the Environmental Protection Agency regulations published in the Federal Register at 55 FR 5910-5915, February 13, 1991, and at 55 FR 55114, November 24, 1992.

Exclusion of Certain Wastes The Environmental Protection Agency amended the federal regulations to exclude from the definition of solid waste those coke by-product residues that are recycled by being returns to coke ovens as a feedstock to produce coke; returned to the tar recovery process as a feedstock to produce coal tar; or mixed with coal tar prior to coal tar refining or sale. The Agency also excluded the similarly-situated hazardous waste K087 when recycled in those ways. These amendments mirror the Agency’s amendments.

The promulgation of these amendments provide state equivalency with the regulatory requirements of the Environmental Protection Agency.

This Basis and Purpose incorporates by reference the preamble language for this amendment published in the Federal Register at 57 FR 27880-27888 on June 22, 1992. _________________________________________________________________________ Editor’s Notes 6 CCR 1007-3 has been divided into smaller sections for ease of use.
