ASTM D7392-07(2013)

5.1 EPA regulations require Portland cement plants that burn hazardous waste to use BLDs or PMDs to provide either a relative or an absolute indication of PM concentration and to alert the plant operator of the need to inspect PM control equipment or initiate corrective action. EPA and others have not established for these applications specific design and performance specifications for these instruments. The design and performance specifications and test procedures contained in this practice will help ensure that measurement systems are capable of providing reliable monitoring data.

5.2 This practice identifies relevant information and operational characteristics of BLD and PMD monitoring devices for Portland cement kiln systems. This practice will assist equipment suppliers and users in the evaluation and selection of appropriate monitoring equipment.

5.3 This practice requires that tests be conducted to verify manufacturer’s published specifications for detection limit, linearity, thermal stability, insensitivity to supply voltage variations and other factors so that purchasers can rely on the manufacturer’s published specifications. Purchasers are also assured that the specific instrument has been tested at the point of manufacture and shown to meet selected design and performance specifications prior to shipment.

5.4 This practice requires that the manufacturer develop and provide to the user written procedures for installation start-up, operation, maintenance, and quality assurance of the equipment. This practice requires that these same procedures are used for a field performance demonstration of the BLD or PMD monitoring equipment at a Portland cement plant.

5.5 The applicable test procedures and specifications of this practice are selected to address the equipment and activities that are within the control of the manufacturer.

5.6 This practice also may serve as the basis for third party independent audits of the certification procedures used by manufacturers of PMD or BLD equipment.

1.1 This practice covers the procedure for certifying particulate matter detectors (PMDs) and bag leak detectors (BLDs) that are used to monitor particulate matter (PM) emissions from kiln systems at Portland cement plants that burn hazardous waste. It includes design specifications, performance specifications, test procedures, and information requirements to ensure that these continuous monitors meet minimum requirements, necessary in part, to monitor reliably PM concentrations to indicate the need for inspection or corrective action of the types of air pollution control devices that are used at Portland cement plants that burn hazardous waste.

1.2 This practice applies specifically to the original manufacturer, or to those involved in the repair, remanufacture, or resale of PMDs or BLDs.

1.3 This practice applies to (Note 1: This practice has been developed based on careful consideration of the nature and variability of PM concentrations, effluent conditions, and the type, configuration, and operating characteristics of air pollution control devices used at Portland cement plants that burn hazardous waste.

1.4 This practice applies to Portland cement kiln systems subject to PM emission standards contained in 40 CFR 63, Subpart EEE.
