BAM-1022 Continuous Particulate Monitor Bid Specifications
This is a bid specification document from the Alabama Department of Environmental Management (ADEM) for the procurement of a BAM-1022 Continuous Particulate Monitor or equivalent. The document establishes comprehensive technical and general specifications for an EPA Class III Federal Equivalency Method (EQPM-1013-209) monitor utilizing beta-attenuation technology to measure PM2.5 particulate matter concentrations. The monitor must operate within relative humidity levels from 0% to 90% non-condensing, collect samples on mechanically-advanced filter tape, automatically measure and collect hourly averages with user-selectable short-term averages of 5 to 60 minutes, and continuously store at least 22,500 hourly averages. The equipment must include a vacuum pump and sample inlet heater, be housed in a weatherproof enclosure with a separable pump box, and transmit data hourly via Ethernet connection using a wireless modem with data accessibility through USB port or remote access via Comet software.
The monitor specifications require a measurement range of -15 to 10,000 micrograms per cubic meter, operating temperature capability from -30 to +50.0 degrees Celsius, and a sample flow rate of 16.7 liters per minute with ±2.0% tolerance. The equipment must achieve a lower detectable limit of less than 1.0 microgram per cubic meter for 24-hour readings and less than 4.8 micrograms per cubic meter for 1-hour readings, with measurement and data resolution of 0.1 and 1.0 micrograms per cubic meter respectively. The monitor requires 115VAC power, includes a 14C beta source of 60±15 Ci, and utilizes a scintillation photomultiplier tube detector. The equipment must meet or exceed US-EPA Class III PM2.5 Federal Equivalency Method standards for both additive and multiplicative bias. Delivery is required to Gina Curvin at 1350 Coliseum Boulevard, Montgomery, AL 36110.

BAM-1022 CONTINUOUS PARTICULATE (PM2.5) MONITOR
General Specifications:
• The monitor must be an Environmental Protection Agency (EPA) Class III Federal Equivalency Method
(EQPM-1013-209) and must include any accessories necessary to maintain this equivalency.
• The monitor must use the Beta-Attenuation process for determining particulate matter (PM) concentrations.
• The monitor must utilize a very sharp cut cyclone to limit PM size to 2.5 microns or smaller.
• The monitor must have the ability to operate during relative humidity levels from 0% to 90% non-condensing.
• The sample must be collected on filter tape; the tape must be mechanically aligned under the sample inlet after completing a beta ray transmission reading to determine the initial filter tape concentration (zero) and a post sample reading must be collected to determine PM2.5 concentrations of the sample.
• Must have the ability to sample continuously with automatic tape advance.
• Must have the ability to automatically measure and collect hourly averages with user selectable short-term averages of 5 to 60 minutes.
• Must have at least one isolated analog output; switch selectable 0 to 1 VDC, 0 to 2.5 VDC or 0-5 VDC.
• Must have the ability to internally store at least 22,500 hourly averages.
• Must be able to transmit data hourly over Ethernet connection using a wireless modem.
• Must have all data files accessible and retrievable via USB port or access files remotely using Comet software.
• Monitor to be supplied with vacuum pump and sample inlet heater.
• Monitor is integrated into its own, weatherproof enclosure and sits on a separable, pump box.
Technical Specifications:
• RANGES: -15 microgram per cubic meter – 10,000 microgram per cubic meter.
• OPERATING TEMPERATURE: -30 to + 50.0 degrees Celsius.
• SAMPLE FLOW RATE: 16.7 liters/minute +/- 2.0%.
• LOWER DETECTABLE LIMIT: < 1.0 microgram per cubic meter for 24-hour readings and <
4.8 micrograms per cubic meter for 1-hour readings.
• SPAN CHECK: Manual audits performed with zero and span foils (included).
• POWER REQUIREMENTS: 115VAC
• MEASUREMENT RESOLUTION: 0.1 micrograms per cubic meter or better
• DATA RESOLUTION: 1.0 micrograms per cubic meter or better
• ACCURACY: Must meet or exceed US-EPA Class III PM2.5 FEM standards for additive and multiplicative bias
• BETA SOURCE: 14C, 60 µCi ± 15 µCi
• DETECTOR TYPE: Scintillation Photomultiplier Tube
• DATA STORAGE: 22,500 records (2.6 years of 1 record/hour).
