|CORRECTIVE ACTION PLAN – PARTS A AND B|
A facility that has sustained a confirmed petroleum release at concentrations or volumes exceeding the allowable standards is required to submit a Corrective Action Plan (CAP) - Part A. A CAP - Part A normally includes the installation of three groundwater monitoring wells. During installation of these wells, soil and groundwater samples are collected and assayed for the presence of petroleum constituents. A survey of potential receptors, including drinking water supplies and surface water bodies, is conducted. An estimate of the direction of groundwater flow is calculated to determine whether contamination is likely to impact nearby receptors. If free product is detected during field activities, a program for recovery is immediately implemented, with approval from the owner of the site. Initiating immediate free product recovery reduces the contaminant migration potential and can significantly reduce the final cost of the project. Should contaminant levels require a more aggressive approach, a CAP - Part B will be required.
A CAP - Part B either details completed computer-generated groundwater contaminant fate and transport modeling and monitoring of the site, or proposed active remediation strategies for the contaminant plume. Ranger aggressively utilizes computer modeling to determine whether the contamination is predicted to impact potential receptors. Should groundwater modeling predict that no impact to potential receptors will occur, Ranger will propose groundwater monitoring at the site, to ensure the validity of the computer model. At the end of the monitoring program, and assuming that the model’s predicted results remain valid, a ‘No Further Action’ status will be requested.
If the groundwater model predicts that an impact will occur to potential receptors, Ranger will install and maintain a cost-effective remediation system to reduce contamination to levels that will not cause future impact. Upon achieving site remediation, a ‘No Further Action’ status will be requested for the site.
