Chapter 2 - CLANDESTINE LAB TESTING AND REMEDIATION
Section 2-8 - Sampling of ISDS, Soils, and Drain Traps
Current through September 21, 2024
(a) Where an ISDS exists that is connected to the facility being assessed, or may have been used for disposal of production wastes, it shall be tested as follows.
(b) Initial screening shall be performed with a portable Photoionization Detector (PID) with 10.2 eV lamp or greater or portable Flame Ionization Detector (FID) and field pH measurement. If PID or FID readings of 1 ppm or greater are obtained, or pH is measured at 8 or 5, a sludge sample shall be collected for laboratory analysis. Samples shall be collected at the following locations:
|
Type |
Location |
|
One chamber tank with one lid |
under solids layer at lid |
|
One chamber tank with two lids |
under solids layer under second (outlet) lid |
|
Two chamber tank |
under solids layer at baffle in first chamber |
|
Tank with no lid |
any accessible location |
(c) Laboratory analyses shall be performed for hazardous characteristics using the following methods, or equivalent methods approved by the U.S. Environmental Protection Agency and/or Wyoming Department of Environmental Quality:
|
Test |
Standard |
|
Ignitability |
EPA SW846 Method 1010 |
|
Corrosivity |
EPA SW846 Method 1110 |
|
Toxicity for VOCs |
EPA SW846 Method 8260B |
|
Reactivity |
EPA SW846 Method 9014 and 9034 |
(d) Target compound sampling in ISDS is not required. If an ISDS is found to contain waste that is hazardous according to the above tests, or if VOCs are detected, the Wyoming Department of Environmental Quality shall be notified and shall be asked to determine requirements applicable to cleanup of the ISDS-related portion of the site.
(e) The land around the structures in the assessment shall be visually inspected for signs of waste disposal associated with the Clanlab, including residual chemical containers, stained soils or signs of chemical dumping, disposal into wells or surface water, and burn piles. Any signs of such disposal shall be documented. The Wyoming Department of Environmental Quality shall be requested to provide guidance on any soil or groundwater assessment and remediation as appropriate that shall be conducted in relation to the possible disposal.
(f) Sampling of ISDSs, Soils, and Drain Traps - Accessible drain traps in the building shall be screened with the PID or FID and field pH. If PID or FID readings of 1 ppm or greater or pH is measured at 8 or 5, requirements of the Department of Environmental Quality shall be followed.
