What is the observation interval for a method 203c test?

You must record opacity observations to the nearest 5 percent at 5- second intervals on an observational record sheet. Each observation recorded represents the average of emissions for the 5-second period.

What is EPA method 9?

A Method 9 test involves the determination of plume opacity. Opacity is the amount of light obscured by pollution. A person conducting a Method 9 must be certified. Method 9 can be found in 40 Code of Federal Regulations, Part 60, Appendix A.

What is the EPA method for THM?

EPA 524.2 is used to determine the concentrations of Total Trihalomethanes (TTHMs) in drinking water. Total Trihalomethanes are volatile organic compounds listed in the National Primary Drinking Water Regulations. EPA 524.2 is performed using gas chromatography/mass spectrometry (GC/MS).

What is the EPA method for TCLP metals?

The TCLP Method 1311 is a leaching procedure that is used to evaluate a sample to see if it exhibits the RCRA characteristic of toxicity, as defined in 40 CFR 261.24. As part of the TCLP process, the sample is leached with a specific acidic solution and the resulting liquid leachate is subsequently analyzed.

What is the EPA method 203A?

It is a method of determining the average opacity from a source. For this Method, the readings are taken at 15 second intervals, and +are then averaged over a six minute interval. 2.2 METHOD 203A (to be promulgated) Method 203A is also taken at 15 second intervals.

What is the EPA reference method 203B?
