Section 1.0 Introduction
This document presents required methods for demonstrating compliance with the regulations for boilers and industrial furnaces (BIFs) burning hazardous waste in subch. H. Included in this document are:
1. Performance Specifications for Continuous Emission Monitoring (CEM) of Carbon Monoxide, Oxygen, and Hydrocarbons in Stack Gases.
2. Procedures for Estimating the Toxicity Equivalency of Chlorinated Dibenzo-p-dioxin and Dibenzofuran Congeners.
3. Hazardous Waste Combustion Air Quality Screening Procedures (HWCAQSP).
4. Simplified Land Use Classification Procedure for Compliance with Tier I and Tier II Limits.
5. Statistical Methodology for Bevill Residue Determinations.
6. Procedures for Determining Default Values for Air Pollution Control System Removal Efficiencies.
7. Procedures for Determining Default Values for Partitioning of Metals, Ash, and Total Chloride/Chlorine.
8. Alternate Methodology for Implementing Metals Controls.
a. Sampling and analytical methods for multiple metals, hexavalent chromium, HCl and chlorine, polychlorinated dibenzo-pdioxins and dibenzofurans, and aldehydes and ketones can be found in “Test Methods for Evaluating Solid Wastes, Physical/Chemical Methods” (EPA Publication SW– 846). Additional methods referenced in subch. H but not included in this document can be found in 40 CFR parts 60 and 61, and “Test Methods for Evaluating Solid Wastes, Physical/Chemical Methods", SW-846, incorporated by reference in s. NR 660.11.
b. The CEM performance specifications of section 2.0, the relevant sampling Methods 0011, 0023A, 0050, 0051, 0060, and 0061 of SW–846, incorporated by reference in s. NR 660.11, and the toxicity equivalency procedure for dioxins and furans of section 4.0 are required procedures for determining compliance with BIF regulations. For the determination of chloride from HCl/Cl2 emission sampling train, use appropriate methods. For the determination of carbonyl compounds by high-performance liquid chromatography, use appropriate methods. The CEM performance specifications and the S&A methods are interim. The finalized CEM performance specifications and methods will be published in SW-846 or 40 CFR parts 60 and 6l.

Performance Specifications For
Continuous Emission Monitoring Systems
2.l Performance Specifications for Continuous Emission Monitoring of Carbon Monoxide and Oxygen for
Incinerators, Boilers, and Industrial Furnaces
Burning Hazardous Waste
2.1.1 Applicability and Principle
2.1.1.1 Applicability. These performance specifications apply to carbon monoxide (CO) and oxygen (O2) 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 licenses. 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.
2.1.1.2 Principle. 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.
2.1.2 Definitions
2.1.2.1 Continuous Emission Monitoring System (CEMS). A continuous monitor is one in which the sample to be analyzed 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.
2.1.2.2 Monitoring System Types. The specifications require CEMSs capable of accepting calibration gases. Alternative system designs may be used if approved by the department. There are 2 basic types of monitoring systems: extractive and in-situ.
2.1.2.2.1 Extractive. 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.
2.1.2.2.2 In-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.
2.1.2.3 Instrument 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 0 and the range expressed only as the maximum.
2.1.2.4 Span or Span Value. Full scale instrument measurement range.
2.1.2.5 Calibration 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.
