9VAC25-580-280: Corrective action plan

A. At any point after reviewing the information submitted in compliance with 9VAC25-580-240, 9VAC25-580-250, and 9VAC25-580-260, the department may require owners and operators to submit additional information or to develop and submit a corrective action plan for responding to contaminated soils and groundwater. If a plan is required, owners and operators must submit the plan according to a schedule and format established by the department. Alternatively, owners and operators may, after fulfilling the requirements of 9VAC25-580-240, 9VAC25-580-250, and 9VAC25-580-260, choose to submit a corrective action plan for responding to contaminated soil and groundwater. In either case, owners and operators are responsible for submitting a plan that provides for adequate protection of human health and the environment as determined by the department and must modify their plan as necessary to meet this standard.

B. In conjunction with the information provided under subdivision A 2 of 9VAC25-580-260 (site assessment, risk (exposure) assessment, and remediation assessment), the corrective action plan must include the following information:

1. Detailed conceptual design including narrative description of technologies and how they will be applied at the site;

2. Projected remediation end points/degree of remediation;

3. Schedule of project implementation;

4. Schedule to achieve projected end points;

5. Operational and post-operational monitoring schedules (to include data submittals);

6. Proposed disposition of any wastes and discharges (if applicable);

7. Actions taken to obtain any necessary federal, state and local permits to implement the plan; and

8. Proposed actions to notify persons directly affected by the release or the planned corrective action.

C. The department will approve the corrective action plan only after ensuring that implementation of the plan will adequately protect human health, safety, and the environment. In making this determination, the department will consider the following factors as appropriate:

1. The physical and chemical characteristics of the regulated substance, including its toxicity, persistence, and potential for migration;

2. The hydrogeologic characteristics of the facility and the surrounding area;

3. The proximity, quality, and current and future uses of nearby surface water and groundwater;

4. The potential effects of residual contamination on nearby surface water and groundwater;

5. The site, risk (exposure), and remediation assessments as required by subdivision A 2 of 9VAC25-580-260; and

6. Any information assembled in compliance with this part.

D. Upon approval of the corrective action plan or as directed by the department, owners and operators must implement the plan, including modifications to the plan made by the department. They must monitor, evaluate, and report the results of implementing the plan in accordance with a schedule and in a format established by the department.

E. Owners and operators may, in the interest of minimizing environmental contamination and promoting more effective cleanup, begin cleanup of soil and groundwater before the corrective action plan is approved provided that they:

1. Notify the department of their intention to begin cleanup and obtain written approval to proceed with an agreed upon activity;

2. Comply with any conditions imposed by the department, including halting cleanup or mitigating adverse consequences from cleanup activities; and

3. Incorporate these self-initiated cleanup measures in the corrective action plan that is submitted to the department for approval.
