Multiple Efforts Contributing to BP Water Technology Decisions

Internal ReviewBP and consultants with global refinery and other industry experience are evaluating and designing source control and water treatment options.

Expert AnalysisExpert consultants are conducting detailed analysis of ideas presented by others to determine if they may be applicable at Whiting.

PWI / Argonne ProjectScientific experts are studying emerging technologies and approaches to minimize discharges into Lake Michigan.

Petroleum Environmental Research Forum (PERF)Industry group is researching and developing environmental technologies for the petroleum industry.

Overview

•Collaboration of Purdue Calumet Water Institute and Argonne National Laboratory

•Develop a list of emerging technologies that may provide wastewater treatment options to BP’s Whiting Refinery expansion

•Conduct a comparative analysis of overall discharges into Lake Michigan

•Could have applications for other dischargers around the Great Lakes

•Phase I: November 2007-June 2008•Phase II: Through November 2009

Objectives of the Study

•Screen emerging technologies that could address wastewater treatment challenges along the Great Lakes:

•Ammonia•Total suspended solids•Metals (e.g. mercury)

•Conduct a comparative analysis of related discharge issues that may help policymakers better understand and address environmental concerns.

Definitions of Technology Categories

•Emerging

•Embryonic: technologies in the development stage and/or tested at laboratory or bench scale

• Innovative: technologies that have been…•tested at a full-scale demonstration site•available and implemented on a limited basis

•Established: technologies that are proven and commercially viable

External Reviewers

Report

Review matrix will be used to provide both qualitative and quantitative assessment of the screened technologies.

Status

•Acquired and analyzed data of the current wastewater treatment plant (WWTP) system

•Established a process to maintain integrity of the project

•Determined standard protocols of investigation, Quality Assurance (QA) methodologies and ranking criteria to ensure technical integrity and uniformity in evaluation

•Identified some technologies for the screening process

•Established screening criteria and a review matrix

16

Next Steps for Technology Screening

•Complete search for promising technologies•Inviting technology vendors

•Collate all data in an initial screen•Convene technical review panel•Prepare final report•Continue public outreach and dissemination of information•Move to Phase II

17

Comparative Discharges Study

•Contact Regulators to obtain discharge data- Some information received, other pending

•Search literature for non-point discharge sources (started)•Assemble database frame (started)•Enter and analyze data (started)•Geographic Information System-based report

Phase I – Lower Lake Michigan (June 2008)Phase II – Entire Lake Michigan (November 2009)
