The CONDITION of each PIECE OF EQUIPMENT is evaluated using five criteria: • Physical condition based on visual inspection – Almost as reliable as predictive maintenance, especially when combined with other factors. • Age factor – Evaluate condition based on useful life, frequency of operation and whether rebuilt. • O&M Protocols – Completeness of manuals, records and SOPs • Repair history – A refinement on Reliability. • Current Operational Status – Out of service and not repairable or operating with no discernible problems? 3/15/2013 4

• The recording should fully document the inspection with suitable quality video and audio. • The inspection should provide an unobstructed view of the entire pipe and use reverse set-ups where necessary to complete the inspection. • Pipe must be adequately cleaned to see any structural defects or construction features. • Care must be exercised to insure acceptable lighting is provided, particularly in larger diameter pipe. 3/15/2013 7
Codes organized into 4 Families: • Structural Defects – 13 groups • Operational and Maintenance Defects – 6 groups • Construction Features – 4 groups • Other 3/15/2013 8
Grade 5 Major Defects that should be reviewed and prioritized for repair or reassessment Grade 4 Significant Defects that will likely change over time and should be monitored Grade 3 Moderate Defects but little change in condition expected Grade 2 Minor Defects Grade 1 Excellent structural condition 3/15/2013 9

• The sustainability plan defines your mission ◦ What are your environmental priorities? ◦ What are the expectations of your customers? ◦ How will you pay for it? • Once you know your mission then the criticality of each asset can be evaluated on a scale of 1 (low importance) to 5 (mission critical) 3/15/2013 16
ASSET RANKING • The Business Risk Score for any given asset is derived by multiplying the condition score by the criticality score. • Results in a score between 1 and 25 3/15/2013 17
