Cite this Code:CFR

To cite the regulations in this volume use title, part and section number. Thus, 40 CFR 266.20 refers to title 40, part 266, section 20. Explanation

The Code of Federal Regulations is a codification of the general and permanent rules published in the Federal Register by the Executive departments and agencies of the Federal Government. The Code is divided into 50 titles which represent broad areas subject to Federal regulation. Each title is divided into chapters which usually bear the name of the issuing agency. Each chapter is further subdivided into parts covering specific regulatory areas.

Each volume of the Code is revised at least once each calendar year and issued on a quarterly basis approximately as follows:

Title 1 through Title 16

as of January 1

Title 17 through Title 27

as of April 1

Title 28 through Title 41

as of July 1

Title 42 through Title 50

as of October 1

The appropriate revision date is printed on the cover of each volume.

LEGAL STATUS

The contents of the Federal Register are required to be judicially noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie evidence of the text of the original documents (44 U.S.C. 1510).

 HOW TO USE THE CODE OF FEDERAL REGULATIONS

The Code of Federal Regulations is kept up to date by the individual issues of the Federal Register. These two publications must be used together to determine the latest version of any given rule.

To determine whether a Code volume has been amended since its revision date (in this case, July 1, 2005), consult the “List of CFR Sections Affected (LSA),” which is issued monthly, and the “Cumulative List of Parts Affected,” which appears in the Reader Aids section of the daily Federal Register. These two lists will identify the Federal Register page number of the latest amendment of any given rule.

 EFFECTIVE AND EXPIRATION DATES

Each volume of the Code contains amendments published in the Federal Register since the last revision of that volume of the Code. Source citations for the regulations are referred to by volume number and page number of the Federal Register and date of publication. Publication dates and effective dates are usually not the same and care must be exercised by the user in determining the actual effective date. In instances where the effective date is beyond the cut-off date for the Code a note has been inserted to reflect the future effective date. In those instances where a regulation published in the Federal Register states a date certain for expiration, an appropriate note will be inserted following the text.

 OMB CONTROL NUMBERS

The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires Federal agencies to display an OMB control number with their information collection request. Many agencies have begun publishing numerous OMB control numbers as amendments to existing regulations in the CFR. These OMB numbers are placed as close as possible to the applicable recordkeeping or reporting requirements.

 OBSOLETE PROVISIONS

Provisions that become obsolete before the revision date stated on the cover of each volume are not carried. Code users may find the text of provisions in effect on a given date in the past by using the appropriate numerical list of sections affected. For the period before January 1, 2001, consult either the List of CFR Sections Affected, 1949-1963, 1964-1972, 1973-1985, or 1986-2000, published in 11 separate volumes. For the period beginning January 1, 2001, a “List of CFR Sections Affected” is published at the end of each CFR volume.

 INCORPORATION BY REFERENCE

What is incorporation by reference? Incorporation by reference was established by statute and allows Federal agencies to meet the requirement to publish regulations in the Federal Register by referring to materials already published elsewhere. For an incorporation to be valid, the Director of the Federal Register must approve it. The legal effect of incorporation by reference is that the material is treated as if it were published in full in the Federal Register (5 U.S.C. 552(a)). This material, like any other properly issued regulation, has the force of law.

What is a proper incorporation by reference? The Director of the Federal Register will approve an incorporation by reference only when the requirements of 1 CFR part 51 are met. Some of the elements on which approval is based are:

(a) The incorporation will substantially reduce the volume of material published in the Federal Register.

(b) The matter incorporated is in fact available to the extent necessary to afford fairness and uniformity in the administrative process.

(c) The incorporating document is drafted and submitted for publication in accordance with 1 CFR part 51.

Properly approved incorporations by reference in this volume are listed in the Finding Aids at the end of this volume.

What if the material incorporated by reference cannot be found? If you have any problem locating or obtaining a copy of material listed in the Finding Aids of this volume as an approved incorporation by reference, please contact the agency that issued the regulation containing that incorporation. If, after contacting the agency, you find the material is not available, please notify the Director of the Federal Register, National Archives and Records Administration, Washington DC 20408, or call 202-741-6010.

 CFR INDEXES AND TABULAR GUIDES

A subject index to the Code of Federal Regulations is contained in a separate volume, revised annually as of January 1, entitled CFR Index and Finding Aids. This volume contains the Parallel Table of Statutory Authorities and Agency Rules (Table I). A list of CFR titles, chapters, and parts and an alphabetical list of agencies publishing in the CFR are also included in this volume.

An index to the text of “Title 3—The President” is carried within that volume.

The Federal Register Index is issued monthly in cumulative form. This index is based on a consolidation of the “Contents” entries in the daily Federal Register.

A List of CFR Sections Affected (LSA) is published monthly, keyed to the revision dates of the 50 CFR titles.

 REPUBLICATION OF MATERIAL

There are no restrictions on the republication of textual material appearing in the Code of Federal Regulations.

 INQUIRIES

These performance specifications apply to carbon monoxide (CO) and oxygen (O<E T="52">2</E>) continuous emission monitoring systems (CEMSs) installed on incinerators, boilers, and industrial furnaces burning hazardous waste. The specifications include procedures which are intended to be used to evaluate the acceptability of the CEMS at the time of its installation or whenever specified in regulations or permits. The procedures are not designed to evaluate CEMS performance over an extended period of time. The source owner or operator is responsible for the proper calibration, maintenance, and operation of the CEMS at all times.</P> <P>2.1.1.2Principle. Installation and measurement location specifications, performance and equipment specifications, test and data reduction procedures, and brief quality assurance guidelines are included in the specifications. Calibration drift, relative accuracy, calibration error, and response time tests are conducted to determine conformance of the CEMS with the specifications.</P> <HD SOURCE="HD3">2.1.2Definitions</HD> <P>2.1.2.1Continuous Emission Monitoring System (CEMS). A continuous monitor is one in which the sample to be analyzed <PRTPAGE P="84"/>passes the measurement section of the analyzer without interruption, and which evaluates the detector response to the sample at least once each 15 seconds and computes and records the results at least every 60 seconds. A CEMS consists of all the equipment used to acquire data and includes the sample extraction and transport hardware, the analyzer(s), and the data recording/processing hardware and software.</P> <P>2.1.2.2Monitoring System Types. The specifications require CEMSs capable of accepting calibration gases. Alternative system designs may be used if approved by the Regional Administrator. There are two basic types of monitoring systems: extractive and in-situ.</P> <P>2.1.2.2.1Extractive. Systems that use a pump or other mechanical, pneumatic, or hydraulic means to draw a sample of the stack or flue gas and convey it to a remotely located analyzer.</P> <P>2.1.2.2.2In-situ. Systems that perform an analysis without removing a sample from the stack. Point in-situ analyzers place the sensing or detecting element directly in the flue gas stream. Cross-stack in-situ analyzers measure the parameter of interest by placing a source beam on one side of the stack and the detector (in single-pass instruments) or a retroreflector (in double-pass instruments) on the other side, and measuring the parameter of interest (e.g., CO) by the attenuation of the beam by the gas in its path.</P> <P>2.1.2.3Instrument Measurement Range. The difference between the minimum and maximum concentration that can be measured by a specific instrument. The minimum is often stated or assumed to be zero and the range expressed only as the maximum.</P> <P>2.1.2.4Span or Span Value. Full scale instrument measurement range.</P> <P>2.1.2.5Calibration Drift (CD). The difference in the CEMS output readings from the established reference value after a stated period of operation during which no unscheduled maintenance, repair, or adjustment takes place. A CD test is performed to demonstrate the stability of the CEMS calibration over time.</P> <P>2.1.2.6Response Time. The time interval between the start of a step change in the system input (e.g., change of calibration gas) and the time when the data recorder displays 95 percent of the final value.</P> <P>2.1.2.7Accuracy. A measure of agreement between a measured value and an accepted or true value, expressed as the percentage difference between the true and measured values relative to the true value. For these performance specifications, accuracy is checked by conducting a calibration error (CE) test and a relative accuracy (RA) test. Certain facilities, such as those using solid waste or batch-fed processes, may observe long periods of almost no CO emissions with brief, high-level CO emission spikes. These facilities, as well as facilities whose CO emissions never exceed 5-10 ppm, may need to be exempted from the RA requirement because the RA test procedure cannot ensure acquisition of meaningful test results under these conditions. An alternative procedure for accuracy determination is described in section 2.1.9.</P> <P>2.1.2.8Calibration Error (CE). The difference between the concentration indicated by the CEMS and the known concentration of the cylinder gas. A CE test procedure is performed to document the accuracy and linearity of the monitoring equipment over the entire measurement range.</P> <P>2.1.2.9Relative Accuracy (RA). A comparison of the CEMS response to a value measured by a performance test method (PTM). The PA test is used to validate the calibration technique and verify the ability of the CEMS to provide representative and accurate measurements.</P> <P>2.1.2.10Performance Test Method (PTM). The sampling and analysis procedure used to obtain reference measurements for comparison to CEMS measurements. The applicable test methods are Method 10, 10A, or 10B (for the determination of CO) and Method 3 or 3A (for the determination of 0<E T="51">2</E>). These methods are found in 40 CFR part 60, appendix A.</P> <P>2.1.2.11Performance Specification Test (PST) Period. The period during which CD, CE, response time, and RA tests are conducted.</P> <P>2.1.2.12Centroidal Area. A concentric area that is geometrically similar to the stack or duct cross section and is no greater than 1 percent of the stack or duct cross-sectional area.</P> <HD SOURCE="HD3">2.1.3Installation and Measurement Location Specifications</HD> <P>2.1.3.1CEMS Installation and Measurement Locations. The CEMS shall be installed in a location in which measurements representative of the source's emissions can be obtained. The optimum location of the sample interface for the CEMS is determined by a number of factors, including ease of access for calibration and maintenance, the degree to which sample conditioning will be required, the degree to which it represents total emissions, and the degree to which it represents the combustion situation in the firebox. The location should be as free from in-leakage influences as possible and reasonably free from severe flow disturbances. The sample location should be at least two equivalent duct diameters downstream from the nearest control device, point of pollutant generation, or other point at which a change in the pollutant concentration or emission rate occurs and at least 0.5 diameter upstream from the exhaust or control device. The equivalent duct diameter is calculated as per 40 CFR part 60, appendix A, method 1, <PRTPAGE P="85"/>section 2.1. If these criteria are not achievable or if the location is otherwise less than optimum, the possibility of stratification should be checked as described in Section 2.1.3.3 to determine whether the location would cause failure of the relative accuracy test.</P> <P>2.1.3.1.1For extractive or point in-situ CEMSs, the measurement point should be within or centrally located over the centroidal area of the stack or duct cross section.</P> <P>2.1.3.1.2For cross-stack CEMSs, the effective measurement path should (1) have at least 70 percent of the path within the inner 50 percent of the stack or duct cross-sectional area or (2) be centrally located over any part of the centroidal area.</P> <P>2.1.3.1.3Both the CO and O<E T="52">2</E> monitors should be installed at the same general location. If this is not possible, they may be installed at different locations if the effluent gases at both sample locations are not stratified and there is no in-leakage of air between sampling locations.</P> <P>2.1.3.2Performance Test Method (PTM) Measurement Location and Traverse Points.</P> <P>2.1.3.2.1Select an accessible PTM measurement point at least two equivalent diameters downstream from the nearest control device, the point of CO generation, or other point at which a change in the CO concentration may occur, and at least a half equivalent diameter upstream from the effluent exhaust or control device. When pollutant concentration changes are due solely to diluent leakage (e.g., air heater leakages) and CO and O<E T="52">2</E> are simultaneously measured at the same location, one half diameter may be used in place of two equivalent diameters. The CEMS and PTM locations need not be the same.</P> <P>2.1.3.2.2Select traverse points that ensure acquisition of representative samples over the stack or duct cross section. At a minimum, establish a measurement line that passes through the centroidal area in the direction of any expected stratification. If this line interferes with the CEMS measurements, displace the line up to 30 cm (or 5 percent of the equivalent diameter of the cross section, whichever is less) from the centroidal area. Locate three traverse points at 17, 50, and 83 percent of the measurement line. If the measurement line is no longer than 2.4 meters and pollutant stratification is not expected, the tester may choose to locate the three traverse points on the line at 0.4, 1.2, and 2.0 meters from the stack or duct wall. This option must not be used at a site located within eight equivalent diameters downstream of a flow disturbance. The tester may select other traverse points, provided that they can be shown to the satisfaction of the Administrator to provide a representative sample over the stack or duct cross-section. Conduct all necessary PTM tests within 3 cm of the selected traverse points. Sampling must not be performed within 3 cm of the duct or stack inner wall.</P> <P>2.1.3.3Stratification Test Procedure. Stratification is defined as a difference in excess of 10 percent between the average concentration in the duct or stack and the concentration at any point more than 1.0 meter from the duct or stack wall. To determine whether effluent stratification exists, a dual probe system should be used to determine the average effluent concentration while measurements at each traverse point are being made. One probe, located at the stack or duct centroid, is used as a stationary reference point to indicate the change in effluent concentration over time. The second probe is used for sampling at the traverse points specified in method 1, appendix A, 40 CFR part 60. The monitoring system samples sequentially at the reference and traverse points throughout the testing period for five minutes at each point.</P> <HD SOURCE="HD3">2.1.4CEMS Performance and Equipment Specifications</HD> <P>Table 2.1-1summarizes the performance specifications for the CEMSs. Two sets of standards for CO are given; one for low-range and another for high-range measurements. The high-range specifications relate to measurement and quantification of short duration high concentration peaks, while the low-range specifications relate to the overall average operating condition of the burning device. The dual-range specifications can be met by using (1) one analyzer for each range, (2) a dual range unit, or (3) a single measurement range instrument capable of meeting both specifications with a single unit. Adjustments cannot be made to the analyzer between determinations of low- and high-level accuracy within the single measurement range. In the second case, when the concentration exceeds the span of the lower range, the data acquisition system recorder shall switch to the high range automatically.</P> <P>2.1.4.1CEMS Span Value. In order to measure high and low concentrations with the same or similar degree of accuracy, the maximum ranges (span values) are specified for low and high range analyzers. The span values are listed in Table 2.1-2.

The owner or operator must choose calibration gas concentrations (or calibration filters for in-situ systems) that include zero and high-level calibration values for the daily calibration checks. For a single measurement range monitor, three CO calibration gas concentrations (or calibration filters for in-situ systems) shall be used, i.e., the zero and high-level concentrations of the low-range CO analyzer and the high-level concentration of the high-range CO analyzer.</P> <P>2.1.4.2.1The zero level for the CO or O<E T="52">2</E> analyzer may be between zero and 20 percent of the span value, e.g., 0-40 ppm for low-range CO analyzer, 0-600 ppm for the high-range CO analyzer, and 0-5 percent for the O<E T="52">2</E> analyzer (for Tier I).</P> <P>2.1.4.2.2The high-level concentration for the CO or O<E T="52">2</E> analyzer shall be between 50 and 90 percent of the span value, i.e., 100-180 ppm for the low-range CO analyzer, 1500-2700 ppm for the high-range CO analyzer, and 12.5-22.5 percent O<E T="52">2</E> for the O<E T="52">2</E> analyzer.</P> <P>2.1.4.3Data Recorder Scale. The strip chart recorder, computer, or digital recorder must be capable of recording all readings within the CEMS's measurement range and shall have a resolution of 0.5 percent of span value, i.e., 1 ppm CO for low-range CO analyzer, 15 ppm CO for high-range CO analyzer, and 0.1 percent O<E T="52">2</E> for the O<E T="52">2</E> analyzer.</P> <P>2.1.4.4Response Time. The response time for the CO or O<E T="52">2</E> monitor shall not exceed 2 minutes to achieve 95 percent of the final stable value.</P> <P>2.1.4.5Calibration Drift. The CEMS must allow the determination of CD at the zero and high-level values. The CD must be determined separately for CO and O<E T="52">2</E> monitors in terms of concentration. The CO CEMS calibration response must not drift or deviate from the reference value of the calibration gas (or calibration filters for in-situ systems) by more than 3 percent of the span value after each 24-hour period of the 7-day test, i.e., 6 ppm CO for the low-range analyzer (Tier I) and 90 ppm for the high-range analyzer, at both zero and high levels. The O<E T="52">2</E> monitor calibration response must not drift or deviate from the reference value by more than 0.5 percent O<E T="52">2</E> at both zero and high -levels.</P> <P>2.1.4.6Relative Accuracy. The result of the PA test of the CO CEMS (which incorporates the O<E T="52">2</E> monitor) must be no greater than 10 percent of the mean value of the PTM results or must be within 10 ppm CO of the PTM results, whichever is less restrictive. The ppm CO concentration shall be corrected to 7 percent O<E T="52">2</E> before calculating the RA.</P> <P>2.1.4.7Calibration Error. The mean difference between the CEMS and reference values at all three test points (see Table 2.1-3) must be no greater than 5 percent of span value for CO monitors (i.e., 10 ppm CO for low range Tier I CO analyzers and 150 ppm CO for high range CO analyzers) and 0.5 percent for O<E T="52">2</E> analyzers.</P> <P>2.1.4.8Measurement and Recording Frequency. The sample to be analyzed shall pass through the measurement section of the analyzer without interruption. The detector shall measure the sample concentration at least once every 15 seconds. An average emission rate shall be computed and recorded at least once every 60 seconds.</P> <P>2.1.4.9Hourly Rolling Average Calculation. The CEMS shall calculate every minute an hourly rolling average, which is the arithmetic mean of the 60 most recent 1-minute average values.</P> <P>2.1.4.10Retest. If the CEMS produces results within the specified criteria, the test is successful. If the CEMS does not meet one or more of the criteria, the necessary corrections must be made and the performance tests repeated.</P> <HD SOURCE="HD3">2.1.5Test Periods</HD> <P>2.1.5.1Pretest Preparation Period. Install the CEMS, prepare the PTM test site according to the specifications in section 2.1.3, and prepare the CEMS for operation and calibration according to the manufacturer's written instructions. A pretest conditioning period similar to that of the 7-day CD test is recommended to verify the operational status of the CEMS.</P> <P>2.1.5.2Calibration Drift Test Period. While the facility is operating under normal <PRTPAGE P="87"/>conditions, determine the CD at 24-hour intervals for seven consecutive days according to the procedure given in section 2.1.6.1. All CD determinations must be made following a 24-hour period during which no unscheduled maintenance, repair, or adjustment takes place. If the combustion unit is taken out of service during the test period, record the onset and duration of the downtime and continue the calibration drift test when the unit resumes operation.</P> <P>2.1.5.3Relative Accuracy Test Period. Conduct the RA test according to the procedure in section 2.1.6.4 while the facility is operating under normal conditions. RA testing for CO and O<E T="52">2</E> shall be conducted simultaneously so that the results can be calculated for CO corrected to 7 percent O<E T="52">2</E>. The RA test shall be conducted during the CD test period. It is emphasized that during the CD test period, no adjustments or repairs may be made to the CEMS other than routine calibration adjustments performed immediately following the daily CD determination.</P> <P>2.1.5.4Calibration Error Test and Response Time Test Periods.

The gas shall pass through all filters, scrubbers, conditioners, and other CEMS components used during normal sampling. If periodic automatic or manual adjustments are made to the CEMS zero and calibration settings, conduct the CD test immediately before these adjustments, or conduct it in such a way that the CD can be determined.

For extractive systems, introduce the calibration gases at the probe as near to the sample location as possible. For in-situ system, introduce the zero gas at a point such that all components active in the analysis are tested. When the system output has stabilized (no change greater than 1 percent of full scale for 30 seconds), switch to monitor stack effluent and wait for a stable value. Record the time (upscale response time) required to reach 95 percent of the final stable value.</P> <P>2.1.6.2.2Next, introduce a high-level calibration gas and repeat the above procedure.

These performance specifications apply to hydrocarbon (HC) continuous emission monitoring systems (CEMSs) installed on incinerators, boilers, and industrial furnaces burning hazardous waste. The specifications include procedures which are intended to be used to evaluate the acceptability of the CEMS at the time of its installation or whenever specified in regulations or permits. The procedures are not designed to evaluate CEMS performance over an extended period of time. The source owner or operator is responsible for the proper calibration, maintenance, and operation of the CEMS at all times.</P> <P>2.2.1.2Principle. A gas sample is extracted from the source through a heated sample line and heated filter (except as provided by section 2.2.10) to a flame ionization detector (FID). Results are reported as volume concentration equivalents of propane. Installation and measurement location specifications, performance and equipment specifications, test and data reduction procedures, and brief quality assurance guidelines are included in the specifications. Calibration drift, calibration error, and response time tests are conducted to determine conformance of the CEMS with the specifications.</P> <HD SOURCE="HD3">2.2.2Definitions</HD> <P>2.2.2.1Continuous Emission Monitoring System (CEMS).

That portion of the system that is used for one or more of the following: Sample acquisition, sample transportation, sample conditioning, or protection of the analyzer from the effects of the stack effluent.</P> <P>2.2.2.1.2Organic Analyzer. That portion of the system that senses organic concentration and generates an output proportional to the gas concentration.</P> <P>2.2.2.1.3Data Recorder. That portion of the system that records a permanent record <PRTPAGE P="92"/>of the measurement values. The data recorder may include automatic data reduction capabilities.</P> <P>2.2.2.2Instrument Measurement Range. The difference between the minimum and maximum concentration that can be measured by a specific instrument. The minimum is often stated or assumed to be zero and the range expressed only as the maximum.</P> <P>2.2.2.3Span or Span Value. Full scale instrument measurement range.</P> <P>2.2.2.4Calibration Gas. A known concentration of a gas in an appropriate diluent gas.</P> <P>2.2.2.5Calibration Drift (CD). The difference in the CEMS output readings from the established reference value after a stated period of operation during which no unscheduled maintenance, repair, or adjustment takes place. A CD test is performed to demonstrate the stability of the CEMS calibration over time.</P> <P>2.2.2.6Response Time. The time interval between the start of a step change in the system input (e.g., change of calibration gas) and the time when the data recorder displays 95 percent of the final value.</P> <P>2.2.2.7Accuracy. A measurement of agreement between a measured value and an accepted or true value, expressed as the percentage difference between the true and measured values relative to the true value. For these performance specifications, accuracy is checked by conducting a calibration error (CE) test.</P> <P>2.2.2.8Calibration Error (CE). The difference between the concentration indicated by the CEMS and the known concentration of the cylinder gas. A CE test procedure is performed to document the accuracy and linearity of the monitoring equipment over the entire measurement range.</P> <P>2.2.2.9Performance Specification Test (PST) Period. The period during which CD, CE, and response time tests are conducted.</P> <P>2.2.2.10Centroidal Area. A concentric area that is geometrically similar to the stack or duct cross section and is no greater than 1 percent of the stack or duct cross-sectional area.</P> <HD SOURCE="HD3">2.2.3Installation and Measurement Location Specifications</HD> <P>2.2.3.1CEMS Installation and Measurement Locations. The CEMS shall be installed in a location in which measurements representative of the source's emissions can be obtained. The optimum location of the sample interface for the CEMS is determined by a number of factors, including ease of access for calibration and maintenance, the degree to which sample conditioning will be required, the degree to which it represents total emissions, and the degree to which it represents the combustion situation in the firebox. The location should be as free from in-leakage influences as possible and reasonably free from severe flow disturbances. The sample location should be at least two equivalent duct diameters downstream from the nearest control device, point of pollutant generation, or other point at which a change in the pollutant concentration or emission rate occurs and at least 0.5 diameter upstream from the exhaust or control device. The equivalent duct diameter is calculated as per 40 CFR part 60, appendix A, method 1, section 2.1. If these criteria are not achievable or if the location is otherwise less than optimum, the possibility of stratification should be investigated as described in section 2.2.3.2. The measurement point shall be within the centroidal area of the stack or duct cross section.</P> <P>2.2.3.2Stratification Test Procedure. Stratification is defined as a difference in excess of 10 percent between the average concentration in the duct or stack and the concentration at any point more than 1.0 meter from the duct or stack wall. To determine whether effluent stratification exists, a dual probe system should be used to determine the average effluent concentration while measurements at each traverse point are being made. One probe, located at the stack or duct centroid, is used as a stationary reference point to indicate the change in effluent concentration over time. The second probe is used for sampling at the traverse points specified in 40 CFR part 60 appendix A, method 1. The monitoring system samples sequentially at the reference and traverse points throughout the testing period for five minutes at each point.</P> <HD SOURCE="HD3">2.2.4CEMS Performance and Equipment Specifications</HD> <P>If this method is applied in highly explosive areas, caution and care shall be exercised in choice of equipment and installation.</P> <P>2.2.4.1Flame Ionization Detector (FID) Analyzer.

The procedure is based on extensive short-term modeling of 11 generic source types and on a set of adjustment factors for estimating annual average concentrations from short-term concentrations.

To ensure a sufficient degree of conservatism, the HWCAQSP may not be used if any of the five screening procedure limitations listed below are true:</P> <P>• The facility is located in a narrow valley less than 1 km wide;</P> <P>• The facility has a stack taller than 20 m and is located such that the terrain rises to the stack height within 1 km of the facility;</P> <P>• The facility has a stack taller than 20 m and is located within 5 km of the shoreline of a large body of water;</P> <P>• The facility property line is within 200 m of the stack and the physical stack height is less than 10 m; or</P> <P>• On-site receptors are of concern, and stack height is less than 10 m.</P> <P>If any of these criteria are met or the Director determines that this procedure is not appropriate, then detailed site-specific modeling or modeling using the “Screening Procedures for Estimating the Air Quality Impact of Stationary Sources,” EPA -450/4-88-010, Office of Air Quality Planning and Standards, August 1988, is required. Detailed site-specific dispersion modeling must conform to the EPA “Guidance on Air Quality Models (Revised)”, EPA 450/2-78-027R, Office of Air Quality Planning and Standards, Research Triangle Park, North Carolina, July 1986.

The methodology is con-serv-a-tive in nature and es-ti-ma-tes dis-pers-ion coefficients <SU>1</SU> <FTREF/> based on facility-specific information.</P> <FTNT> <P> <SU>1</SU> The term dispersion coefficient refers to the change in ambient air concentration (µg/m<SU>3</SU>) resulting from a source with an emission rate of 1 g/sec.</P> </FTNT> <P>The screening procedure can be used to determine emissions limits at sites where the nearest meteorological (STAR) station is not representative of the meteorology at the site. If the screen shows that emissions from the site are adequately protective, then the need to collect site-specific meteorological data can be eliminated.</P> <P>The screening procedure is generally most helpful for facilities meeting one or more of the following conditions:</P> <P>• Multiple stacks with substantially different release specifications (e.g., stack heights differ by >50 percent, exit temperatures differ by >50 °K, or the exit flow rates differ by more than a factor of 2),</P> <P>• Terrain located between 1 km and 5 km from the site increases in elevation by more than the physical height of the shortest stack (i.e., the facility is located in complex terrain), or</P> <P>• Significant distance between the fa-cil-i-ty's stacks and the site boundary [guid-ance on de-ter-min-ing whether a distance is “sig-nif-i-cant” is provided in Step 6(B) of the procedure].</P> <P>Steps 1 through 9 of the screening procedure present a simplified method for determining emissions based on the use of the “worst-case” stack. If the simplified method shows that desired feed rates result in emissions that exceed allowable limits for one or more pollutants, a refined analysis to examine the emissions from each stack can be conducted. This multiple-stack method is presented in Step 10.<PRTPAGE P="100"/> </P> <P>The steps involved in screening methodology are as follows: </P> <FP SOURCE="FP-1">Step 1.

Urban/rural classification is needed because dispersion rates differ between urban and rural areas and thus, the risk per unit emission rate differs accordingly. The combination of greater surface roughness (more buildings/structures to generate turbulent mixing) and the greater amount of heat released from the surface in an urban area (generates buoyancy-induced mixing) produces greater rates of dispersion. The emission limit tables in the regulation, therefore, distinguish between urban and rural areas.</P> <P>EPA guidance (EPA 1986) <SU>1</SU> provides two alternative procedures to determine whether the character of an area is predominantly urban or rural. One procedure is based on land use typing and the other is based on population density. Both procedures require consideration of characteristics within a 3-km radius from a source, in this case the facility stack(s). The land use typing method is preferred because it more directly relates to the surface characteristics that affect dispersion rates. The remainder of this discussion is, therefore, focused on the land use method.</P> <P>While the land use method is more direct, it can also be labor-intensive to apply. For this discussion, the land use method has been simplified so that it is consistent with EPA guidance (EPA 1986; Auer 1978), while streamlining the process for the majority of applications so that a clear-cut decision can be made without the need for detailed analysis. Table 6.0-1 summarizes the simplified approach for classifying areas as urban or rural. As shown, the applicant always has the option of applying standard (i.e., more detailed) analyses to more accurately distinguish between urban and rural areas.

Within These primary classes, subclasses are identified, as shown in table 6.0-1. The goal is to estimate the percentage of the area within a 3-km radius that is urban type and the percentage that is rural type. Industrial and commercial areas are classified as urban; agricultural areas are classified as rural.</P> <P>The delineation of urban and rural areas, however, can be more difficult for the residential type areas shown in table 6.0-1. The degree of resolution shown in table 6.0-1 for residential areas often cannot be identified without conducting site area inspections and/or referring to zoning maps. This process can require extensive analysis, which, for many applications, can be greatly streamlined without sacrificing confidence in selecting the appropriate urban or rural classification.</P> <P>The fundamental simplifying assumption is based on the premise that many applications will have clear-cut urban/rural designations, i.e., most will be in rural settings that can be definitively characterized through a brief review of topographical maps. The color coding on USGS topographical maps provides the most effective means of simplifying the typing scheme. The suggested typing designations for the color codes found on topographical maps are as follows:</P> <FP SOURCE="FP-1"> <E T="03">Green</E>Wooded areas (rural).</FP> <FP SOURCE="FP-1"> <E T="03">White</E>White areas generally will be treated as rural. This code applies to areas that are unwooded and do not have densely packed structures which would require the pink code (house omission tint). Parks, industrial areas, and unforested rural land will appear as white on the topographical maps. Of these categories, only the industrial areas could potentially be classified <PRTPAGE P="115"/>as urban based on EPA 1986 or Auer 1978. Industrial areas can be easily identified in most cases by the characteristics shown in Figure 6.0-1. For this simplified procedure, white areas that have an industrial classification will be treated as urban areas.</FP> <GPH DEEP="470" SPAN="2"> <GID>EC01AU92.037</GID> </GPH> <PRTPAGE P="116"/> <HD SOURCE="HD1">Section 7.0Statistical Methodology for Bevill Residue Determinations</HD> <P>This section describes the statistical comparison of waste-derived residue to normal residue for use in determining eligibility for the Bevill exemption under 40 CFR 266.112.</P> <HD SOURCE="HD2">7.1Comparison of Waste-Derived Residue to Normal Residue</HD> <P>To be eligible for the Bevill exclusion from the definition of hazardous waste under 40 CFR 266.112(b)(1), waste-derived residue must not contain Appendix VIII, Part 261, constituents that could reasonably be attributable to the hazardous waste (toxic constituents) at concentrations significantly higher than in residue generated without burning or processing hazardous waste (normal residue). Concentrations of toxic constituents in normal residue are determined based on analysis of a minimum of 10 samples representing a minimum of 10 days of operation. The statistically-derived concentrations in normal residue are determined as the upper tolerance limit (95% confidence with a 95% proportion of the sample distribution) of the normal residue concentrations. The upper tolerance limit is to be determined as described in Section 7.2 below. If changes in raw materials or fuels could lower the statistically-derived concentrations of toxic constituents of concern, the statistically-derived baseline must be re-established for any such mode of operation with the new raw material or fuel.</P> <P>Concentrations of toxic constituents in waste-derived residue are determined based on the analysis of one or more samples collected over a compositing period of not more than 24 hours. Mulitple samples of the waste-derived residue may be analyzed or subsamples may be composited for analysis, provided that the sampling period does not exceed 24 hours. If more than one sample is analyzed to characterize the waste-derived residue generated over a 24-hour period, the arithmetic mean of the concentrations must be used as the waste-derived concentration for each constituent.</P> <P>The concentration of a toxic constituent in the waste-derived residue is not considered to be significantly higher than in the normal residue (i.e., the residue passes the Bevill test for that constituent) if the concentration in the waste-derived residue does not exceed the statistically-derived concentration.</P> <HD SOURCE="HD2">7.2Calculation of the Upper Tolerance Limit</HD> <P>The 95% confidence with 95% proportion of the sample distribution (upper tolerance limit) is calculated for a set of values assuming that the values are normally distributed. The upper tolerance limit is a one-sided calculation and is an appropriate statistical test for cases in which a single value (the waste-derived residue concentration) is compared to the distribution of a range of values (the minimum of 10 measurements of normal residue concentrations). The upper tolerance limit value is determined as follows: </P> <FP SOURCE="FP-1">UTL = X + (K)(S)</FP> <FP>where</FP> <FP SOURCE="FP-1">X = mean of the normal residue concentrations, X = X <E T="52">i</E>/n,</FP> <FP SOURCE="FP-1">K = coefficient for sample size n, 95% confidence and 95% proportion,</FP> <FP SOURCE="FP-1">S = standard deviation of the normal residue concentrations,</FP> <FP>S = (Σ(X<E T="52">i</E> − X)<SU>2</SU>/(n − 1))<SU>0</SU>.<SU>5</SU>, and</FP> <FP SOURCE="FP-1">n = sample size.</FP> <P>The values of K at the 95% confidence and 95% proportion, and sample size n are given in Table 7.0-1.</P> <P>For example, a normal residue test results in 10 samples with the following analytical results for toxic constituent A:</P> <GPOTABLE CDEF="s10,12" COLS="2" OPTS="L2"> <BOXHD> <CHED H="1">Sample No.</CHED> <CHED H="1">Concentration of constituent A (ppm)</CHED> </BOXHD> <ROW> <ENT I="01">1</ENT> <ENT>10</ENT> </ROW> <ROW> <ENT I="01">2</ENT> <ENT>10</ENT> </ROW> <ROW> <ENT I="01">3</ENT> <ENT>15</ENT> </ROW> <ROW> <ENT I="01">4</ENT> <ENT>10</ENT> </ROW> <ROW> <ENT I="01">5</ENT> <ENT>7</ENT> </ROW> <ROW> <ENT I="01">6</ENT> <ENT>12</ENT> </ROW> <ROW> <ENT I="01">7</ENT> <ENT>10</ENT> </ROW> <ROW> <ENT I="01">8</ENT> <ENT>16</ENT> </ROW> <ROW> <ENT I="01">9</ENT> <ENT>15</ENT> </ROW> <ROW> <ENT I="01">10</ENT> <ENT>10</ENT> </ROW> </GPOTABLE> <P>The mean and the standard deviation of these measurements, calculated using the above equations, are 11.5 and 2.9, respectively.

The Agency is aware that concentration data of this type may not always be distributed normally, particularly when concentrations are near the detection limits. There are a number of procedures that can be used to test the distribution of a data set. For example, the Shapiro-Wilk test, examination of a histogram or plot of the data on normal probability paper, and examination of the coefficient of skewness are methods that may be applicable, depending on the nature of the data (References 1 and 2).<PRTPAGE P="117"/> </P> <P>If the concentration data are not adequately represented by a normal distribution, the data may be transformed to attain a near normal distribution. The Agency has found that concentration data, especially when near detection levels, often exhibit a lognormal distribution. The assumption of a lognormal distribution has been used in various programs at EPA, such as in the Office of Solid Waste Land Disposal Restrictions program for determination of BDAT treatment standards. The transformed data may be tested for normality using the procedures identified above. If the transformed data are better represented by a normal distribution than the untransformed data, the transformed data should be used in determining the upper tolerance limit using the procedures in Section 7.2 above.</P> <P>In all cases where the owner or operator wishes to use other than an assumption of normally distributed data or believes that use of an alternate statistical approach is appropriate to the specific data set, he/she must provide supporting rationale in the operating record that demonstrates that the data treatment is based upon sound statistical practice.</P> <HD SOURCE="HD2">7.4Nondetect Values</HD> <P>The Agency is developing guidance regarding the treatment of nondetect values (data where the concentration of the constituent being measured is below the lowest concentration for which the analytical method is valid) in carrying out the statistical determination described above. Until the guidance information is available, facilities may present their own approach to the handling of nondetect data points, but must provide supporting rationale in the operating record for consideration by the Director.</P> <GPOTABLE CDEF="s10,10" COLS="2" OPTS="L2"> <TTITLE>Table 7.0-1—K Values for 95% Confidence and 95% Proportion</TTITLE> <BOXHD> <CHED H="1">Sample size (n)</CHED> <CHED H="1">K</CHED> </BOXHD> <ROW> <ENT I="01">10</ENT> <ENT>2.911</ENT> </ROW> <ROW> <ENT I="01">11</ENT> <ENT>2.815</ENT> </ROW> <ROW> <ENT I="01">12</ENT> <ENT>2.736</ENT> </ROW> <ROW> <ENT I="01">13</ENT> <ENT>2.670</ENT> </ROW> <ROW> <ENT I="01">14</ENT> <ENT>2.614</ENT> </ROW> <ROW> <ENT I="01">15</ENT> <ENT>2.566</ENT> </ROW> <ROW> <ENT I="01">16</ENT> <ENT>2.523</ENT> </ROW> <ROW> <ENT I="01">17</ENT> <ENT>2.486</ENT> </ROW> <ROW> <ENT I="01">18</ENT> <ENT>2.458</ENT> </ROW> <ROW> <ENT I="01">19</ENT> <ENT>2.423</ENT> </ROW> <ROW> <ENT I="01">20</ENT> <ENT>2.396</ENT> </ROW> <ROW> <ENT I="01">21</ENT> <ENT>2.371</ENT> </ROW> <ROW> <ENT I="01">22</ENT> <ENT>2.350</ENT> </ROW> <ROW> <ENT I="01">23</ENT> <ENT>2.329</ENT> </ROW> <ROW> <ENT I="01">24</ENT> <ENT>2.303</ENT> </ROW> <ROW> <ENT I="01">25</ENT> <ENT>2.292</ENT> </ROW> </GPOTABLE> <HD SOURCE="HD2">7.5References</HD> <P>1.

See certification of precompliance under 40 CFR 266.103(b). This documentation also establishes interim status feed rate and operating limits for the facility. For the initial certification, estimates of emissions and system removal efficiencies (SREs) can be made to establish the operating limits. Subsequently, owners or operators must use emissions testing to demonstrate that emissions do not exceed allowable levels, and to establish operating limits. See 40 CFR 266.103(c). However, initial estimates of emissions for certification of precompliance can be based on estimated or established SREs.</P> <P>The SRE combines the effect of partitioning of the chorine, metals, or PM and the air pollution control system removal efficiency (APCS RE) for these pollutants. The SRE is defined as:</P> <FP SOURCE="FP-1">SRE=(species input—species emitted) / species input</FP> <P>The SRE can be calculated from the partitioning factor (PF) and APCS RE by the following formula: </P> <FP SOURCE="FP-1">SRE=1—[(PF/l00) X (1—APCS RE/100)]</FP> <FP>where:</FP> <FP SOURCE="FP-1">PF=percentage of the pollutant partitioned to the combustion gas</FP> <P>Estimates of the PF and/or the APCS RE can be based on either EPA's default values or engineering judgement.

EPA's default values for partitioning of these pollutants are described in section 9.0.</P> <P>Guidelines for the use of engineering judgement to estimate APCS REs or PFs are described in section 9.4.</P> <HD SOURCE="HD2">8.1APCS RE Default Values for Metals</HD> <P>EPA's default assumptions for APCS RE for metals are shown in Table 8.1-1. The default values in the table are conservative estimates of the removal efficiencies for metals in BIFs, depending on the volatility of the metal and the type of APCS.</P> <P>The volatility of a metal depends on the temperature, the thermal input, the chlorine <PRTPAGE P="118"/>content of the waste, and the identity and concentration of the metal. Metals that do not vaporize at combustion zone temperatures are classified as “nonvolatile”. Such metals typically enter the APCS in the form of large particles that are removed relatively easily. Metals that vaporize in the combustion zone and condense before entering the APCS are classified as “volatile”. Such metals typically enter the APCS in the form of very fine, submicron particles that are rather inefficiently removed in many APCSs. Metals that vaporize in the combustion zone and do not condense before entering the APCS are classified as “very volatile”. Such metals enter the APCS in the form of a vapor that is very inefficiently removed in many APCSs.</P> <P>Typically, BIFs have combustion zone temperatures high enough to vaporize any hazardous metal at concentrations sufficient to exceed risk-based emission limits. For this reason, the default assumption is that there are no nonvolatile metals. Tables 8.1-2 and 8.1-3 are used to determine whether metals are classified as “volatile” or “very volatile” depending on the temperature entering the APCS, the thermal input, and whether the waste is chlorinated or nonchlorinated.</P> <GPOTABLE CDEF="s10,10,10,10" COLS="4" OPTS="L2"> <TTITLE>Table 8.1-1—Air Pollution Control Systems (APCS) and Their Conservatively Estimated Efficiencies for Controlling Toxic Metals (%)</TTITLE> <BOXHD> <CHED H="1">APCS</CHED> <CHED H="1">Metal Volatility</CHED> <CHED H="2">Nonvolatile</CHED> <CHED H="2">Volatile</CHED> <CHED H="2">Very Volatile</CHED> </BOXHD> <ROW> <ENT I="01">WS</ENT> <ENT>40</ENT> <ENT>30</ENT> <ENT>20</ENT> </ROW> <ROW> <ENT I="01">VS-20</ENT> <ENT>80</ENT> <ENT>75</ENT> <ENT>20</ENT> </ROW> <ROW> <ENT I="01">VS-60</ENT> <ENT>87</ENT> <ENT>75</ENT> <ENT>40</ENT> </ROW> <ROW> <ENT I="01">ESP-1</ENT> <ENT>90</ENT> <ENT>75</ENT> <ENT>0</ENT> </ROW> <ROW> <ENT I="01">ESP-2</ENT> <ENT>92</ENT> <ENT>80</ENT> <ENT>0</ENT> </ROW> <ROW> <ENT I="01">ESP-4</ENT> <ENT>95</ENT> <ENT>80</ENT> <ENT>0</ENT> </ROW> <ROW> <ENT I="01">WESP</ENT> <ENT>90</ENT> <ENT>85</ENT> <ENT>40</ENT> </ROW> <ROW> <ENT I="01">FF</ENT> <ENT>90</ENT> <ENT>80</ENT> <ENT>0</ENT> </ROW> <ROW> <ENT I="01">SD/FF</ENT> <ENT>97</ENT> <ENT>90</ENT> <ENT>0</ENT> </ROW> <ROW> <ENT I="01">DS/FF</ENT> <ENT>95</ENT> <ENT>90</ENT> <ENT>0</ENT> </ROW> <ROW> <ENT I="01">IWS</ENT> <ENT>90</ENT> <ENT>87</ENT> <ENT>75</ENT> </ROW> </GPOTABLE> <FP SOURCE="FP-1">WS=Wet Scrubber including: Sieve Tray Tower, Packed Tower, Bubble Cap Tower</FP> <FP SOURCE="FP-1">VS−20=Venturi Scrubber, ca. 20-30 in W.G.

EPA's default assumptions are discussed below for metals, HCl, Cl<E T="52">2</E>, and PM. The default assumptions are used to conservatively predict the partitioning factor for several types of BIFs. Engineering judgement-based partitioning factor estimates are discussed in section 9.4.</P> <HD SOURCE="HD2">9.1Partitioning Default Value for Metals</HD> <P>To be conservative, the Agency is assuming that 100 percent of each metal in each feed stream is partitioned to the combustion gas. Owners/operators may use this default value or a supportable, site-specific value developed following the general guidelines provided in section 9.4.</P> <HD SOURCE="HD2">9.2Special Procedures for Chlorine, HCl, and Cl<E T="52">2</E> </HD> <P>The Agency has established the special procedures presented below for chlorine because the emission limits are based on the pollutants HCl and Cl2 formed from chlorine fed to the combustor. Therefore, the owner/operator must estimate the controlled emission rate of both HCl and Cl<E T="52">2</E> and show that they do not exceed allowable levels.</P> <P>1. The default partitioning value for the fraction of chlorine in the total feed streams that is partitioned to combustion gas is 100 percent. Owners/operators may use this default value or a supportable, site-specific value developed following the general guidelines provided in section 9.4.</P> <P>2. To determine the partitioning of chlorine in the combustion gas to HCl versus Cl<E T="52">2</E>, either use the default values below or use supportable site-specific values developed following the general guidelines provided in section 9.4.</P> <P>• For BIFs excluding halogen acid furnaces (HAFs), with a total feed stream chlorine/hydrogen ratio ≤0.95, the default partitioning factor is 20 percent Cl<E T="52">2</E>, 80 percent HCl.</P> <P>• For HAFs and for BIFs with a total feed stream chlorine/hydrogen ratio >0.95, the default partitioning factor is 100 percent Cl<E T="52">2</E>.</P> <P>3. To determine the uncontrolled (i.e., prior to acid gas APCS) emission rate of HCl and Cl<E T="52">2</E>, multiply the feed rate of chlorine times the partitioning factor for each pollutant. Then, for HCl, convert the chlorine emission rate to HCl by multiplying it by the ratio of the molecular weight of HCl to the molecular weight of Cl (i.e., 36.5/35.5). No conversion is needed for Cl<E T="52">2</E>.</P> <HD SOURCE="HD2">9.3Special Procedures for Ash</HD> <P>This section: (1) Explains why ash feed rate limits are not applicable to cement and light-weight aggregate kilns; (2) presents the default partitioning values for ash; and (3) explains how to convert the 0.08 gr/dscf, corrected to 7% O<E T="52">2</E>, PM emission limit to a PM emission rate.</P> <P> <E T="03">Waiver for Cement and Light-Weight Aggregate Kilns.</E> For cement kilns and light-weight aggregate kilns, raw material feed streams contain the vast majority of the ash input, and a significant amount of the ash in the feed stream is entrained into the kiln exhaust gas. For these devices, the ash content of the hazardous waste stream is expected to have a negligible effect on total ash emissions. For this reason, there is no ash feed rate compliance limit for cement kilns or light-weight aggregate kilns. Nonetheless, cement kilns and light-weight aggregate kilns are required to initially certify that PM emissions are not likely to exceed the PM limit, and subsequently, certify through compliance testing that the PM limit is not exceeded.</P> <P> <E T="03">Default Partitioning Value for Ash.</E> The default assumption for partitioning of ash depends on the feed stream firing system. There are two methods by which materials may be fired into BIFs: Suspension-firing and bed-firing.</P> <P>The suspension category includes atomized and lanced pumpable liquids and suspension-fired pulverized solids. The default partitioning assumption for materials fired by these systems is that 100 percent of the ash partitions to the combustion gas.</P> <P>The bed-fired category consists principally of stoker boilers and raw materials (and in some cases containerized hazardous waste) fed into cement and light-weight aggregate kilns. The default partitioning assumption for materials fired on a bed is that 5 percent of the ash partitions to the combustion gas.</P> <P> <E T="03">Converting the PM Concentration-Based Standard to a PM Mass Emission Rate.</E> The emission limit for BIFs is 0.08 gr/dscf, corrected to 7% 0<E T="52">2</E>, unless a more stringent standard applies [e.g., a New Source Performance Standard (NSPS) or a State standard implemented under the State Implementation Plan (SIP)]. To convert the 0.08 gr/dscf standard to a PM mass emission rate:</P> <P>1. Determine the flue gas 0<E T="52">2</E> concentration (percent by volume, dry) and flue gas flow rate (dry standard cubic feet per minute); and</P> <P>2. Calculate the allowable PM mass emission rate by multiplying the concentration- based PM emission standard times the flue gas flow rate times a dilution correction factor equal to [(21-0<E T="52">2</E> concentration from step 1)/(21-7)].<PRTPAGE P="121"/> </P> <HD SOURCE="HD2">9.4Use of Engineering Judgement To Estimate Partitioning and APCS RE Values</HD> <P>Engineering judgement may be used in place of EPA's conservative default assumptions to estimate partitioning and APCS RE values provided that the engineering judgement is defensible and properly documented. To properly document engineering judgement, the owner/operator must keep a written record of all assumptions and calculations necessary to justify the APCS RE used. The owner/operator must provide this record to the Director upon request and must be prepared to defend the assumptions and calculations used.</P> <P>If the engineering judgement is based on emissions testing, the testing will often document the emission rate of a pollutant relative to the feed rate of that pollutant rather than the partitioning factor or APCS RE.</P> <P>Examples of situations where the use of engineering judgement may be supportable to estimate a partitioning factor, APCS RE, or SRE include:</P> <P>• Using emissions testing data from the facility to support an SRE, even though the testing may not meet full QA/QC procedures (e.g., triplicate test runs). The closer the test results conform with full QA/QC procedures and the closer the operating conditions during the test conform with the established operating conditions for the facility, the more supportable the engineering judgement will be.</P> <P>• Applying emissions testing data documenting an SRE for one metal, including nonhazardous surrogate metals to another less volatile metal.</P> <P>• Applying emissions testing data documenting an SRE from one facility to a similar facility.</P> <P>• Using APCS vendor guarantees of removal efficiency.</P> <HD SOURCE="HD2">9.5Restrictions on Use of Test Data</HD> <P>The measurement of an SRE or an APCS RE may be limited by the detection limits of the measurement technique. If the emission of a pollutant is undetectable, then the calculation of SRE or APCS RE should be based on the lower limit of detectability. An SRE or APCS RE of 100 percent is not acceptable.</P> <P>Further, mass balance data of facility inputs, emissions, and products/residues may not be used to support a partitioning factor, given the inherent uncertainties of such procedures. Partitioning factors other than the default values may be supported based on engineering judgement, considering, for example, process chemistry. Emissions test data may be used to support an engineering judgement-based SRE, which includes both partitioning and APCS RE.</P> <HD SOURCE="HD2">9.5References</HD> <FP SOURCE="FP-1">1.

This is done by determining if the hazardous waste meets the treatment standards in § 268.40, § 268.45, or § 268.49. This determination can be made in either of two ways: testing the waste or using knowledge of the waste. If the generator tests the waste, testing would normally determine the total concentration of hazardous constituents, or the concentration of hazardous constituents in an extract of the waste obtained using test method 1311 in “Test Methods of Evaluating Solid Waste, Physical/Chemical Methods,” EPA Publication SW-846, as referenced in § 260.11 of this chapter, depending on whether the treatment standard for the waste is expressed as a total concentration or concentration of hazardous constituent in the waste's extract. In addition, some hazardous wastes must be treated by particular treatment methods before they can be land disposed and some soils are contaminated by such hazardous wastes. These treatment standards are also found in § 268.40, and are described in detail in § 268.42, Table 1. These wastes, and solids contaminated with such wastes, do not need to be tested (however, if they are in a waste mixture, other wastes with concentration level treatment standards would have to be tested). If a generator determines they are managing a waste or soil contamination with a waste, that displays a hazardous characteristic of ignitability, corrosivity, reactivity, or toxicity, they must comply with the special requirements of § 268.9 of this part in addition to any applicable requirements in this section.</P> <P>(2) If the waste or contaminated soil does not meet the treatment standard: With the initial shipment of waste to each treatment or storage facility, the generator must send a one-time written notice to each treatment or storage facility receiving the waste, and place a copy in the file. The notice must include the information in column <PRTPAGE P="145"/>“268.7(a)(2)” of the Generator Paperwork Requirements Table in § 268.7(a)(4). No further notification is necessary until such time that the waste or facility change, in which case a new notification must be sent and a copy placed in the generator's file.</P> <P>(i) For contaminated soil, the following certification statement should be included, signed by an authorized representative: </P> <EXTRACT> <P>I certify under penalty of law that I personally have examined this contaminated soil and it [does/does not] contain listed hazardous waste and [does/does not] exhibit a characteristic of hazardous waste and requires treatment to meet the soil treatment standards as provided by 268.49(c).</P> </EXTRACT> <P>(ii) [Reserved]</P> <P>(3) If the waste or contaminated soil meets the treatment standard at the original point of generation:</P> <P>(i) With the initial shipment of waste to each treatment, storage, or disposal facility, the generator must send a one-time written notice to each treatment, storage, or disposal facility receiving the waste, and place a copy in the file. The notice must include the information indicated in column “268.7(a)(3)” of the Generator Paperwork Requirements Table in § 268.7(a)(4) and the following certification statement, signed by an authorized representative: </P> <EXTRACT> <P>I certify under penalty of law that I personally have examined and am familiar with the waste through analysis and testing or through knowledge of the waste to support this certification that the waste complies with the treatment standards specified in 40 CFR part 268 subpart D. I believe that the information I submitted is true, accurate, and complete. I am aware that there are significant penalties for submitting a false certification, including the possibility of a fine and imprisonment.</P> </EXTRACT> <P>(ii) For contaminated soil, with the initial shipment of wastes to each treatment, storage, or disposal facility, the generator must send a one-time written notice to each facility receiving the waste and place a copy in the file. The notice must include the information in “268.7(a)(3) of the Generator Paperwork Requirements Table in § 268.7(a)(4).</P> <P>(iii) If the waste changes, the generator must send a new notice and certification to the receiving facility, and place a copy in their files. Generators of hazardous debris excluded from the definition of hazardous waste under § 261.3(f) of this chapter are not subject to these requirements.</P> <P>(4) For reporting, tracking, and recordkeeping when exceptions allow certain wastes or contaminated soil that do not meet the treatment standards to be land disposed: There are certain exemptions from the requirement that hazardous wastes or contaminated soil meet treatment standards before they can be land disposed. These include, but are not limited to case-by-case extensions under § 268.5, disposal in a no-migration unit under § 268.6, or a national capacity variance or case-by-case capacity variance under subpart C of this part. If a generator's waste is so exempt, then with the initial shipment of waste, the generator must send a one-time written notice to each land disposal facility receiving the waste. The notice must include the information indicated in column “268.7(a)(4)” of the Generator Paperwork Requirements Table below. If the waste changes, the generator must send a new notice to the receiving facility, and place a copy in their files.</P> <GPOTABLE CDEF="s100,10C,10C,10C,10C" COLS="5" OPTS="L2"> <TTITLE>Generator Paperwork Requirements Table</TTITLE> <BOXHD> <CHED H="1">Required information</CHED> <CHED H="1">§ 268.7 (a)(2)</CHED> <CHED H="1">§ 268.7 (a)(3)</CHED> <CHED H="1">§ 268.7 (a)(4)</CHED> <CHED H="1">§ 268.7 (a)(9)</CHED> </BOXHD> <ROW> <ENT I="01">1.
