AECOM Authors New Remediation Manual for Petroleum Industry — IPIECA AECOM Remediation Experts author new Good Practice Guide for Management and Remediation of Sites in the Petroleum Industry for The International Petroleum Industry Environmental Conservation Association (IPIECA). Management and remediation of sites in the petroleum industry An IPIECA Good Practice Guide Operations Good Practice Series 2014 www.ipieca.org IPIECA is the London-based global oil and gas industry association for environmental and social issues, with membership covering over half of the world’s oil production, and the industry’s principal channel of communication with the United Nations. AECOM senior remediation and environmental engineers Chris Carleo and Kelly Hansel, working closely with experts from major oil and gas companies, co-authored the IPIECA remediation manual which details strategies and practices for managing contaminant releases to soil and groundwater from petroleum refineries, terminals, gas stations, and exploration and production facilities. The new guide summarizes cleanup principles and approaches, provides a globally applicable risk-based framework for identifying and managing impacts and implementing corrective actions, and aligns innovative and proven risk management and site remediation methodologies to industry standards. AECOM has worked extensively with IPIECA to improve environmental performance and natural resource management across the oil and gas industry especially for operations in developing countries and emerging economies. Earlier, M. Venkatesh, AECOM senior vice president, process engineering authored IPIECA’s Manual on Petroleum Refinery Water and Wastewater Use and Management. “According to M. Venkatesh, “The remediation approaches and techniques we‘ve detailed can be successfully applied at facilities to produce positive environmental outcomes and cost savings,” says Venkatesh, “especially where information on standards and good practices is not readily available.” Chris Carleo has 30 years of experience in site remediation for major industries and expertise in investigation, conceptual site model development, feasibility studies, remedial design and remedial action development. Kelly Hansel has 25 years of experience in remediation of petroleum and other contaminant releases to soil, groundwater, surface water, sediment, and indoor air. M. Venkatesh served as study manager and expert reviewer for the Remediation Manual which is a publicly available document. AECOM’s remediation manual will assist a multitude of oil companies with choosing appropriate remediation techniques for the situation, and introduce newer techniques with best uses, benefits and drawbacks for the various treatment systems.

Management and Remediation of Sites in the Petroleum Industry This manual will assist the petroleum industry in implementing “Good Practices” for remediation management at their facilities. AECOM was commissioned to write a manual outlining “good practices” for remediation management for the petroleum industry. This work was contracted to AECOM based on our extensive experience providing remediation consulting services to petroleum companies worldwide. With over 30 years of experience managing remediation projects for the oil and gas industry, AECOM was uniquely qualified to write this manual. Based on our staff’s extensive experience in the industry, the manual contains an introduction, detailed chapters outlining good practices, as well as a references section to help facilities maintain regulatory compliance. Topics covered include: Conceptual Site Model: Basic Elements • Site physical setting, including soil and groundwater properties • Sources of impacts and contaminants of concern (COCs) • Potential primary sources • Potential migration and exposure pathways • Potential receptors • Other considerations Conceptual Site Model: Development • Preliminary site assessment • Imminent hazard evaluation • Comprehensive (Phase II) environmental sessment Risk-Based Corrective Action • Overview of risk assessment • Risk-based corrective action (RBCA) −− RBCA Tier 1 screening level risk assessment −− RBCA Tier 2 site-specific risk assessment and target levels −− RBCA Tier 3: refining the Tier 2 assessment • Identify remedial action objectives Remedial Technologies: Selection and Implementation • • • • • Considerations for selection and screening Screening criteria Sustainability Remediation approaches Implementation of remediation Closeout Remedial Action • Documentation • Regulatory/stakeholder reporting • Site reuse Further Reading and References Appendix A: Standard and Guidance References Appendix B: Site Investigation • Site investigation methodology −− Work plan −− Health and safety plan −− Utility locating −− Soil and bedrock investigation methods −− Groundwater investigation methods −− Soil and groundwater sample laboratory analyses −− NAPL delineation and evaluation −− Soil vapour and indoor air evaluations −− Soil vapour screening −− Decontamination −− Management of investigation-derived waste (IDW) • Comprehensive site assessment documentation Appendix C: Remediation Technologies • Remediation technologies −− Physical impermeable barriers and encapsulation −− Hydraulic containment −− Skimming −− NAPL recovery with water table depression −− Multi-phase extraction −− Enhanced fluid recovery −− MNA and enhanced bioremediation −− Soil vapour extraction (SVE) −− Air sparging −− Phytoremediation • Ex situ treatment technologies −− Biopiling −− Constructed treatment wetlands For information or assistance with site remediation, contact: www.aecom.com [email protected] [email protected] [email protected]
