On 11/3/2014, we will remove the remaining contaminated soil underneath the skid. We will use a PID, that is set for Ethylene Glycol, to help us determine our clean soil boundary, and also collect confirmation samples.

The number of water wells within a 1/2 mile radius is an estimate based on issued DWR permits. There are 2 domestic water wells and the remaining are groundwater monitoring well permits. Some of DWR permits cover multiple monitoring wells, so there are many more monitoring wells within a 1/2 mile radius. 0 0 0 0 0 0 0 0 0 0 false false 2 1 false false false false false false false false false true false true 15 10 Will remediate remaining contaminated dirt under skid on 11/03/14. 6 400722306 1 2014-11-02T00:00:00-06:00 false true false false On October 24, 2014, an Operator discovered that the packing around the cylinder on a glycol pump at Plant 3 of the Parachute Creek Gas Plant had broke and released approximately 100 gallons of ethylene glycol on the ground.

The contaminated soil that was accessible and not underneath the skid, was immediately cleaned up and placed in a lined containment, ready for disposal. The remaining contaminated soil will be removed on 11/3/2014, and confirmation samples will be taken. Samples will be analyzed to determine that <70 mg/kg has been attained (per Stan Spencer). The packing has been replaced and pump returned to service. Check packing more frequently.
