About this file
Attachment B is a solicitation specification document for the Texas Commission on Environmental Quality (TCEQ) for a Continuous Particulate Monitor Beta Attenuation Monitor. The document details technical specifications for an environmental monitoring instrument designed to continuously measure suspended particulate matter (PM2.5) in ambient air. The monitor must meet U.S. Environmental Protection Agency (EPA) Federal Equivalent Method EQPM-1013-209 and be capable of providing continuous monitoring with sample averaging times of one hour or less. Key technical requirements include functionality in high ambient temperatures and humidity, self-containment, portability, use of a glass fiber filter tape, operation with a BGI very sharp cut cyclone particle size separator, and a sample flow rate of 16.67 liters per minute.
The solicitation requires all items to be new and of current production, with a minimum two-year warranty covering onsite system, parts, and labor. Additional terms include providing two sets of comprehensive manuals, offering in-house training for TCEQ staff at no additional cost, and providing technical support during standard business hours via telephone and email. The document emphasizes the need for a robust, portable monitoring device that can operate in various environmental conditions without requiring secondary shelters or air conditioning, with specific focus on precise particulate matter measurement capabilities for environmental monitoring purposes.

Solicitation Name: Continuous Particulate Monitor Solicitation Number: 582-25-08654
Attachment B
Specifications for Continuous Particulate Monitor Beta Attenuation Monitor
Description: Instrumentation requirements for 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 a glass fiber filter tape for sample measurements.
8. Monitor must be equipped with a BGI very sharp cut cyclone (VSCC) particle size separator.
9. Monitor must operate at a sample flow rate of 16.67 liters per minute.
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.
Solicitation Name: Continuous Particulate Monitor Solicitation Number: 582-25-08654
2. The warranty period should consist of complete coverage of system onsite, parts, and labor for a minimum of two years from the date of acceptance.
3. Two sets of manuals (styled: Instruction Manual, Operator’s Manual, Operation and Service Manual, etc.) must accompany each instrument. The manuals will include complete operating instructions, circuit descriptions, theory of operation, location of controls and switches, software commands, maintenance, and service instructions. The manual will also include schematic diagrams, pneumatic flow charts, lists of commonly replaced parts, warnings, and safety precautions.
4. In-house training for TCEQ staff should be provided at no additional costs to TCEQ for maintenance and diagnostic repair.
5. Technical support must be available for TCEQ staff between the hours of 8 a.m.
and 5 p.m. Central Standard Time (CST) during regular business days, Mondays through Fridays, via both telephone access and electronic mail (e-mail).
