Determine Necessity for test
- Decide on data required
- Determine what testing is needed to determine required data
Determine the Test Objectives
- Regulatory compliance
- Process design data
- Process evaluation
Design the Test Experiment
- Develop sampling approach
- Select test method(s) to meet test data objectives
- Determine adequate gas sample volumes
- Evaluate possible errors and biases, correct approach if necessary
- Determine time required for test with margin for delays
- Estimate the cost of the test and economize when possible or necessary
Prepare Sampling Location(s)
- Inform plant operators of test objectives and requirements for successful completion
- Determine accessibility to duct.
- Does the location have sampling ports installed? If
not, please see our figure of placement of sampling ports for a Round
duct or for a Rectangular duct.
If the type of sampling you need involves manual (eg. Isokinetic) AND
continuous emissions monitoring, you will need to install
an additional CEM sampling port (see the figure).
- Remove obstructions of beams or guardrails
- Install monorail brackets above each manual sampling port. Please see our drawing
of a monorail bracket for details of what it would look like.
- Check if sampling ports can be opened
- Check for in-stack obstructions, such as an opacity monitor
- Check for sufficient space for personnel AND equipment.
- Check for lighting
- Verify scaffolding meets OSHA requirements
- Is a man-lift available? (when proper or reasonable
access is unachievable by any other means)
- Locate Electrical Power (preferably within 50 feet of the sampling location)
- One 20A 115V circuit for each sampling train operating at the same time.
- One 30A 480V circuit for each sampling trailer. (Note this
is a DEECO specific requirement, other companies will have
- Evaluate safety requirements
- What type of PPE (personal protective equipment) will be necessary?
- Fall protection?
- Protective clothing? (eg. long sleeve shirt, splash protection, safety glasses, hard hat)
- Breathing protection? (eg. dust mask, respirator, supplied air, SCBA)
- Note any special equipment needed
Submit test plan to Agency (if necessary)
- Many States require a 30-day advance submittal of this document.
- There could also be a regulatory requirement (e.g. PC MACT 60 days)
Set test dates
This is a basic outline. Please contact DEECO for more help
