Attachment A

Specifications for Continuous Particulate Monitor Beta Attenuation Monitor

Description: Instrumentation requirements for ultra-sensitive continuous monitoring of suspended particulate matter of 2.5 micrometers in diameter (PM2.5) in ambient air by beta attenuation.

MINIMUM GENERAL SPECIFICATIONS

1. Must meet U.S. Environmental Protection Agency (EPA) Federal Equivalent Method

EQPM-1013-209.

2. Monitor must be capable of providing continuous monitoring of PM2.5 data with sample averaging time less than or equal to one hour.

3. Monitor must be capable of running in ambient conditions, specifically must be functional in high ambient temperatures and relative humidity.

A. Must not require collocation with air-conditioning unit in order to function.

B. Must be functional in humid environments without risk of condensation forming in sample lines.

4. Monitor must be self-contained: should not require installation within a secondary shelter. Self-containment should protect instrument from natural elements such as weather (within reason). See item 3 for ambient condition specifications.

5. Monitor must include internal temperature control to maintain the sensor at a constant operating temperature 5-10 degrees above ambient temperature.

6. Monitor must be portable enough to meet the following.

A. Must be able to be located on a rooftop or ground-level B. Must be able to be moved by 1-2 people (within reason) without requiring disassembly

7. Monitor must use polytetrafluoroethylene with polyester backing filter tape for continuous sample measurements.

8. Monitor must be equipped with a BGI very sharp cut cyclone (VSCC) particle size separator.

9. Monitor must meet the following specifications:

A. Operate at a sample flow rate of 16.7 liters per minute.

B. Measurement Range 0 – 10,000 micrograms per cubic meter C. Measurement resolution of 0.1 micrograms per cubic meter D. Lower detection limit of less than 2.4 micrograms per cubic meter E. Operating Temperature -30 degrees to 50 degrees C F: Humidity Range between 0 to 90% relative humidity, non-condensing

10. Monitor must include an ambient temperature, barometric pressure, and relative humidity sensor(s).

ADDITIONAL TERMS AND CONDITIONS

1. All items must be bid new, of current production, and include the manufacturer’s standard parts and accessories.
