END OF RISK ASSESSMENT

Section 1- INTRODUCTION TO THE RISK ASSESSMENT PROCESS

As directed by contract 19IBWC20C0003 between Veolia Water West Operating Services, Inc.

(“Veolia”) and the United States International Boundary and Water Commission (“USIBWC”), Veolia conducted a risk assessment of the South Bay International Wastewater Treatment Plant (“SBIWTP”) in accordance with OMB Circular A-123. The OMB Circular’s stated purpose is to provide “guidance to Federal managers on improving the accountability and effectiveness of Federal programs and operations by establishing, assessing, correcting, and reporting on internal control...to ensure that Federal programs operate and Federal resources are used efficiently and effectively to achieve desired objectives. Programs must operate and resources must be used consistent with agency missions, in compliance with laws and regulations, and with minimal potential for waste, fraud, and mismanagement.” Veolia’s focus remains on the safety, effectiveness, and efficiency of operations while ensuring compliance with applicable laws and regulations. Veolia considers planning and budgeting to mitigate risks as an essential part of the effectiveness of our operations of the SBIWTP.

The focus of Veolia’s Risk Assessment herein is to provide USIBWC with a summary of known risks and or liabilities for continuity of safe and compliant operations. Some of the risks identified have been shown to be mitigated through human intervention in accordance with developed procedures while others require corrective maintenance actions or plant modification consideration.

The following Veolia employees conducted this assessment:

Jacob Schmidt – Plant Superintendent Calvin Carnegie - Senior Director, Technical & Performance Aaditya Raman - President Operations, Southwest Region Roger Bolton - Asset Management

The risk review process involved both onsite and offsite activities to review material status and history, spare parts inventory, process status and history, and operating procedures.

Veolia’s Asset Management team conducted a comprehensive Criticality Risk Assessment and a completion Condition Assessment of all managed assets. Processes and systems with high risk profiles are highlighted in the sections below as are assets in poorer condition. An asset risk calculation is provided and those assets considered in the high risk profile category with high criticality and in poor condition are highlighted and action plans identified. Attached are the complete documents for the Criticality Analysis Report and Condition Assessment that supported these findings.

A systematic relative criticality analysis review was completed for the USIBWC in December 2020.

This process prioritized and ranked assets using a standardized scale accounting for consequence and likelihood of worst case failure scenarios. Key components used for evaluating and cataloging risk include the System Criticality Analysis review and the Asset Condition Assessment review.

The criticality analysis review was completed in a workshop with local plant staff and the company’s Asset Management team. Systems were evaluated and defined with the hierarchy structure developed and assigned to each asset in the Computerized Maintenance Management System (CMMS). Worst case failure scenarios were set for each system considering consequence and likelihood of failure details. For each scenario, key criteria were evaluated using the following Level of Service categories: Safety, Capacity, Environmental/Water Quality, Operating Cost, Stakeholder Impact, and Collateral Impact. Based on the severity of the failure, consequences were assigned rankings of Unacceptable, Major, Undesirable, or Minor risk for each of the Level of Service categories. After final priorities are established, each system is ranked relative to other connecting or related systems in terms of Criticality. Systems and/or assets with higher Level of Service impacts are rated at a higher Criticality. Each system and asset is assigned a criticality ranking of 1, 2, 3, or 4 as defined below:

1 – Minor Failure Effects 2 - Undesirable Failure Effects 3 – Major Failure Effects 4 – Unacceptable Failure Effects

These ranking results are entered into the CMMS for each asset. Criticality ranking can then be used during the maintenance management, maintenance budgeting, and capital planning processes. By utilizing the Criticality rankings in these processes, the asset investment strategy is prioritized in terms of Level of Service impacts for repair and replacement decisions and timelines.

Updates to the criticality analysis are conducted annually.

System Criticality Analysis Results

The complete Criticality Analysis Report for 2022 is attached in the appendices to this report and contains the detailed analysis results including failure scenarios and consequences of failure. For the purposes of the risk assessment report higher risk systems will be evaluated, i.e. systems that rank a level 3 as having major potential failure effects and systems that rank a level 4 as having unacceptable failure effects.

Section 2- Asset Condition Assessment Review

It is important to understand the current operating condition of the asset towards meeting Level of Service expectations to achieve more accurate maintenance and capital planning. Annual condition assessments are being completed for all assets. The condition assessment is intended to be a “snapshot” of the condition of an asset. A ranking number is assigned to the asset based on a deficiency scoring where 1 is new and 4 is failed.

The basic approach for performing the condition assessment entails the use of three major steps which Are:

1) Data Preparation – Extracting or compiling the asset registry from the

CMMS and adding it to the condition assessment tool.

2) Assessment – A process and set of tools by which field evaluation of assets can be accomplished and the results recorded, based on ranking standards. Where available performance testing is completed. Each asset is ranked in multiple areas such as performance, appearance, vibration, reliability, safety, etc.

3) Review – When the ranking is complete, using filtering to review the final scores and make replacement recommendations.

The summary condition score is an integer value on a scale from 1 to 4. The scale is generally as follows:

1 – Like New Condition

2 – Good Condition, Later in Aging

3 – Indications of Wear, Degradation, or Decrease in Performance

4 4 – Failed or Imminently Failing

Higher numerical values represent worst case conditions based on deficiency scoring. Evidence of defects, excessive wear, or aging warrants higher value condition scores. If an asset is in an advanced state of wear or aging, an “end-of-life” can be predicted. For the remaining assets – those in a condition not indicating near term failure – one can “calibrate” the mean expected lifetimes and better predict probable mean lifetimes for the assets. While this predicted end-of-life rating may not be reliable for any one asset, the statistical aggregate provides for a good budgetary planning means and for any given asset, it provides an indicator gauge to help prevent the early onset of failure probabilities. Applying this process to each asset ensures that maintenance management and capital decisions meet the Level of Service business objectives.

Asset Condition Assessment Results

The complete Condition Assessment Report for 2022 is attached in the appendices to this report and contains the detailed analysis results including the scoring for all assets. For the purposes of the risk assessment report poorer condition assets will be evaluated, i.e. assets that rank a level 3 as having indications of wear, degradation, or decrease in performance and assets that rank a level 4 as having failed or are imminently failing

Section 3- Risk Evaluation

This philosophy of risk management is at the core of asset management. Risks are primarily related to the consequences (criticality) associated with the failure occurring on any process equipment (that may, for instance, adversely impact health & safety, the environment or any financial results), and to the likelihood of failure occurrence (condition). Veolia has developed an overall Risk Score by multiplying the asset criticality score by the asset condition score.

When criticality and condition are expressed as numbers, it is common to express the risk index as the product of both figures.

Figure 1 - The Risk Matrix as defined by the Asset Criticality Score multiplied by Asset Condition Score

Condition

4 3 2 1 4 16 12 8 4

Criticality 3 12 9 6 3 2 8 6 4 2 1 4 3 2 1

Asset Risk Evaluation Results

For the purposes of the risk assessment report, poorer condition assets in higher criticality systems will be identified and reviewed. This evaluation included assets with a Criticality score that ranks a level 3 as having major potential failure effects and a level 4 as having unacceptable failure effects and assets with a Condition score that ranks a level 3 as having indications of wear, degradation, or decrease in performance and and a level 4 as having failed or is imminently failing.
