conducted. EPA created a guidance on developing these plans. Some laboratories measure everything out by weight (accounting for the density) to get more accuracy, which is also allowed. Sampling is the physical collection of a representative portion of a universe or whole of a waste or waste treatment residual. What is the correct procedure to meet the ambient temperature requirement for SW-846 Method 1311 (TCLP)? Some forms of treatment are not regulated under RCRA, including treatment of hazardous wastes in an elementary neutralization unit. A lock (LockA locked padlock) or https:// means youve safely connected to the .gov website. (ii) A compressed gas shall be characterized as ignitable if any one of the following occurs: (A) Either a mixture of 13 percent or less (by volume) with air forms a flammable mixture or the flammable range with air is wider than 12 percent regardless of the lower limit. Part 122. Extraction fluid #1 and #2 are supposed to be used for other analytes: Extraction fluid #1 for sites east of the Mississippi River and #2 for sites west of the Mississippi River. Hazardous waste that is destined for land disposal must meet all applicable treatment standards prior to land disposal. On the third item, there are many definitions as to what is a waste or wastewater. (1) A used battery becomes a waste on the date it is discarded (e.g., when sent for reclamation). Clarification on the selection of the extraction fluid for SW-846 Method 1312, SPLP. What test methods are approved for determining if a liquid is ignitable? Therefore, if metals and cyanide analyses are needed, two separate sample aliquots would be extracted with two different fluids. Rather than define those for the method, it is much simpler to just determine if the sample is a soil or not. Memo, Straus to Skoufis; March 6, 1987 (RCRA Online 11224) Memo, Lowrance to Ullrich; June 14, 1990 (RCRA Online #11524). here. (i) The term "compressed gas" shall designate any material or mixture having in the container an absolute pressure exceeding 40 p.s.i. Choosing an item from site when drafting amendatory language for Federal regulations: Comments or questions about document content can not be answered by OFR staff. Keep in mind that this is only a recommendation and use of borosilicate glass is not mandatory. Monthly Call Center Report Question; November 1994 (RCRA Online #13711) ( c) Each hazardous waste listed in this subpart is assigned an EPA Hazardous Waste Number which precedes the name of the waste. In July 1985, EPA issued interim guidance describing certain threshold levels for cyanide- and sulfide-bearing wastes and laboratory methods for evaluating such wastes. In July 1985, EPA issued interim guidance describing certain threshold levels for cyanide and sulfidebearing wastes and laboratory methods for evaluating such wastes. Is the waste stream liable to change such that the other fluid might have to be chosen occasionally? Where can I find guidance on representative sampling? If they meant to analyze by an exact time, the method authors would have put that time into the method. Even though SW-846 Method 9040C (and Method 9045D) are MDP methods and must be followed prescriptively, Section 6.0 of Method 9040C on holding time is not prescriptive. If dilution and internal standards do not work and spike recoveries are still below 50%, then MSA may be the only option left. Memo, Barnes to Fox; May 19, 1988 (RCRA Online #11350). The actual holding time for pH analysis should be specified in the quality assurance plan under which the sample was collected and agreedupon by all stakeholders involved, including those who have to measure the pH (be it in the laboratory or in the field). If other types of glass bottles are providing acceptable blanks for the parameters being monitored, then they are acceptable to use. It is important to note that a generator must still determine if petroleum contaminated media and debris is hazardous for the hazardous waste codes D001 through D017 (Memo, Lowrance to Bevington; November 9, 1990 (RCRA Online #11569)). The second column (Waste Description and Treatment/Regulatory subcategory) describes the waste in more detail. The Hazardous and Solid Waste Amendments (HSWA) to the RCRA prohibitland disposal of restricted hazardous waste. The range of pH allowed is fairly easy to accommodate using regular laboratory glassware and equipment to measure volumes and prepare reagents. This web site is designed for the current versions of (i) 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 must be classed as an organic peroxide unless: (A) The material meets the definition of a Division 1.1, 1.2, or 1.3 explosive, as defined in 261.23(a)(8), in which case it must be classed as an explosive. Environmental Protection Agency. I heard that EPA had withdrawn the method for Reactive Cyanide and Reactive Sulfide as specified in Chapter 7 of SW-846. A liquid and corrodes steel at rate greater than 6.35 mm (approx 1/4 inch) per year at a test temperature of 55 degrees Celsius (40 CFR 261.22). However, there are no specific methods currently available for reactive cyanide and reactive sulfide for reactivity characteristic determination. ( a) A solid waste exhibits the characteristic of ignitability if a representative sample of the waste has any of the following properties: These levels are generally determined by the implementing agency according to risk (57 FR 958, 986; January 9, 1992). In April 1998, EPA withdrew the July 1985 guidance. Can a State determine whether or not soils which contained a listed hazardous waste, but were then treated to below health based concentrations, no longer contain the hazardous waste? A small portion of this table is shown below for purposes of illustration. (4) It is an oxidizer. This attribute of the used oil is irrelevant if the used oil will be burned for energy recovery rather than land disposed. Alternative Treatment Standard for Lab Packs. EPA has not issued guidelines as to when or at what levels environmental media contaminated with hazardous wastes are no longer considered to contain those hazardous wastes. Authority: . For determination of the ignitability characteristic in solid wastes, SW846 Method 1030 should be followed. See 40 CFR section 268.42, Table 1 for a description of hazardous waste treatment technologies. If a waste Characteristic wastes cannot be land disposed until they meet all applicable treatment standards for the waste characteristic and UHCs. Memo, Barnes to Moretta; December 6, 1988 (RCRA Online 11384) Secure .gov websites use HTTPS How is this to be interpreted when analyzing both cyanide and metals on an SPLP extraction? Is it excluded? The codes then dictate the amount and type of treatment a waste needs in order to legally go to a landfill. Read more in the LDR Phase II final rule establishing these debris standards (starting on page 37194 of the August 18, 1992 Federal Register notice (328 pp, 78 MB, About PDF)). "RCRA Waste Sampling and Draft Technical Guidance", updates the information provided in Chapter Nine of SW-846. When a defined term appears in a definition, the defined term is . A lock (LockA locked padlock) or https:// means youve safely connected to the .gov website. Reactive sulfide, formerly described in SW846 Section 7.3.4.2, referred to those sulfide species that could form hydrogen sulfide gas under mildly acidic conditions. Treatment means any method, technique, or process, including neutralization, designed to change the physical, chemical, or biological character or composition of any hazardous waste so as to neutralize such waste, or so as to recover energy or material resources from the waste, or so as to render such waste non-hazardous, or less hazardous; safer to transport, store, or dispose of; or amenable for recovery, amenable for storage, or reduced in volume (40 CFR Section 260.10). Is this true? That is the most conservative approach and should satisfy all auditors or regulators, including NELAC auditors for laboratory certification. Specifically, a waste is classified as an acute hazardous waste if it is any P-listed waste (Section 261.33) or one of the following F-listed wastes: F020, F021, F022, F023, F026, and F027 (Section 261.31). What is a representative sample? Here is a more detailed description of the steps to follow: Nonwastewaters are wastes that do not meet the criteria for wastewaters. Compliance with these numerical standards are based on grab sampling. SW-846 is also available on-line at no cost from the EPA Website. The total surface area of the coupon is the sum of the areas of the two faces of the coupon, plus the area around the outside edge, plus the area around the edge of the hole in the center of the coupon. at 130 F; or any liquid flammable material having a vapor pressure exceeding 40 p.s.i. If the maximum leachable concentration is below the regulatory concentration, the TCLP does not need to be performed. What is meant by a quantity sufficient to present a danger to human health or the environment in 40 CFR 261.23 for the reactivity characteristic for cyanide or sulfide waste? C = Concentration of the analyte in solid portion of the sample (mg/kg) If the total waste analysis data yield a maximum theoretical leachate concentration that equals or exceeds the TC threshold, the data cannot be used to conclusively demonstrate that the waste does not exceed the TC. Additional guidance on the alcohol exclusion is available in the following documents: The equation for the surface area of the stainless steel coupon in Method 1110 is not clear to us. Both Method 1311 and Method 1312 have language specifying the use of an internal calibration quantitation method for each metallic component if the spike recovery for the element is < 50% and the concentration of the contaminant falls in the range from 80 to 100% of the regulatory level. Top eCFR Content 261.21 Characteristic of ignitability. (November, 1999), Pensky-Martens Closed-Cup Method for Determining Ignitability (Method 1010A) (PDF), Setaflash Closed-Cup Method for Determining Ignitability (Method 1020B) (PDF), Ignitability of Solids (Method 1030) (PDF), Corrosivity Towards Steel (Method 1110A) (PDF), Toxicity Characteristic Leaching Procedure (TCLP) (Method 1311) (PDF), Hazardous Waste Characteristics Reference Guide: A User-Friendly Reference Document, October 2009 (PDF), RCRA Training Module - Introduction to Hazardous Waste Identification (PDF), risk assessment described in this document. It should be noted that many organic liquids (even those miscible with water) may interfere with and/or damage pH electrodes. The method indicates that the percent solids be determined as described in Section 7.1 using the nonZHE filtration unit, and if the solids are less than 0.5%, section 7.1.2 directs the user to section 7.3 for volatile compounds. In addition, spent PCE used in dry cleaning is classified as F002 when the spent solvent formulation meets the ten percent (by volume) criterion in the listing (Call Center Monthly Report Question; October 1992,RCRA Online #13565). FAR). (b) A hazardous waste which is identified by a characteristic in this subpart is assigned every EPA Hazardous Waste Number that is applicable as set forth in this subpart. [55 FR 11862, Mar. (2) 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 Method 1110A in Test Methods for Evaluating Solid Waste, Physical/Chemical Methods, EPA Publication SW846, and as incorporated by reference in 260.11 of this chapter. Waste that have not been specifically listed may still be considered a hazardous waste if exhibits one of the four characteristics defined in 40 CFR Part 261 Subpart C - ignitability (D001), corrosivity (D002), reactivity (D003), and toxicity (D004 - D043). I was hoping you could please provide some guidance on Section 7.1.4.1 of the EPA 1311 TCLP method. There are three subcategories of debris: Debris may be comprised of virtually any manufactured object, plant, animal matter or geologic material bigger than a tennis ball. Therefore, the surface area criteria would also apply for the procedure to determine which extraction fluid to use. EPA received many comments regarding the proposed rule for the identification and listing of hazardous waste and the inclusion in the reactivity definition of "any cyanide or sulfide bearing waste which can generate toxic gases, vapors or fumes when exposed to mild acidic or basic conditions.". Memo, Bussard to Wilson; June 14, 1990 (RCRA Online 11523) If it is a waste or solids from wastewater, the pH 4.2 fluid is used by default. This document is available in the following developer friendly formats: Information and documentation can be found in our Since Method 1311 is a Method Defined Parameter (MDP) method, it is exempt from the flexibility clause that is in effect for most of the other SW846 methods. What RCRA hazardous wastes are classified as "acute" hazardous wastes? Is it allowable to increase the strength of the acid solution in SW-846 Method 1311 and use the acid solution to test additional analytes? In particular, SW-846 has been developed by EPA to assist the regulated community in meeting analytical responsibilities under the RCRA program. While these methods have been revised, the regulated community must rely on the older standards specified in the regulation to determine whether or not a waste exhibits the characteristics of ignitability. Sampling is the physical collection of a representative portion of the universe or whole of a waste or waste treatment residual. What is the time limit for filtering the TCLP leachates after completing the tumbling? Choosing an item from There is also an explanation of the ignitability characteristic in Chapter 7 of SW-846, and SW-846 Methods. Sections 7.3.3 and 7.3.4 were amended by the Methods Innovation Rule (SW846 Final Update IIIB) published in the Federal Register, June 14, 2005 (Volume 70, Number 113), to withdraw specific reference to methodologies and threshold concentration levels. What Are the LDR Alternative Treatment Standards? EPA - Energetic Particle Analyzer. Method 9045D may be used to evaluate pH properties of non-aqueous liquids, solids, and sludges, but not for the RCRA characteristic of corrosivity. There are however exceptions. Hazardous organic compounds are converted to ash, carbon dioxide, and water. The first column (waste code) assists the waste handler in locating all the EPA hazardous waste codes applicable to the waste. In April 1998, EPA withdrew the July 1985 guidance in a memo from Bussard and Johnson to Love (RCRA Online #14177 (PDF) (10 pp, 561.3 K, About PDF). (i) The term compressed gas shall designate any material or mixture having in the container an absolute pressure exceeding 40 p.s.i. Consequently, you may not have 1N NaOH, and using the prescribed volumes in the method will give you a pH that is too low. The TCLP Method 1311 is a leaching procedure that is used to evaluate a sample to see if it exhibits the RCRA characteristic of toxicity, as defined in 40 CFR 261.24. The term "alcohol" refers to any alcohol or combination of alcohols (55 FR 22520, 22543; June 1, l990). The inclusion of Method 1110(A) in the regulation was discussed in the original background document. Please do not provide confidential In order for environmental media contaminated with a listed waste to no longer be considered hazardous, the handler of those media must demonstrate to EPA's or the authorized State's satisfaction thatthe mediano longer poses a sufficient health threat to merit RCRA regulation. This requirement applies to all TCLP inorganic analytes and the methods used to determine those analytes, including the current version of ICP Method 6010. ], [45 FR 33119, May 19, 1980, as amended at 51 FR 40636, Nov. 7, 1986; 55 FR 22684, June 1, 1990; 56 FR 3876, Jan. 31, 1991]. According to property (5) under 261.23, a waste is hazardous if it is a cyanide- or sulfide-bearing waste which generates toxic gases or vapors at a quantity sufficient to present a health danger.
