Deputy Director, Utilities Department City of Newport Beach 3300 Newport Blvd. Newport Beach, CA 92658 -8915 PROPOSAL NDE- P891208 Subject: NDE Environmental Corporation Proposal to Perform Leak Pinpointing of Two One -Mile Sections of 3011 Seawater Transmission Line for the City of Newport Beach Dear Mr. Staneart: NDE Environmental Corporation (NDE) is pleased to submit a Plan of Work and Cost Proposal to provide leak pinpointing services for two one -mile sections of 3011 Seawater Transmission Line for the City of Newport Beach. Work will include filling the line with a tracer gas mixture containing Helium up to about 15 psig, tracer detection of Helium using two types of tracer gas detectors in drilled sampling holes spaced 15 feet apart, and acoustic emission measurements using two types of instrumentation. The NDE Cost s based on the following description of the wo•c, planning' of tasks, and schedule. This is a reliable estimate..�f:.major leaks are pinpointed early., and detailed monitoring at 15 ft. intervals is not required. If the 'detailed monitoring..is required, the work will be completed at a ',cosh -no -fo exceed $25;.646: HELIUM TRACER TESTING Once each line section is ready for testing, completely drained and blinded, NDE proposes to fill the section with a mixture of 1% or more Helium in air or Nitrogen. Since the measured leak rates are not small, the apparatus for pressurizing with tracer gas will be mobile so that both lines may be filled from either end. Helium will be detected at other accessible pipeline fittings to assure distribution of tracer throughout the lines. Drawings will be studied prior to work startup to predetermine the most likely locations for leakage along the pipeline. Holes will be bored at 15 ft. spacing above the line in these predetermined "high risk" areas of the pipeline. Additional holes along the remainder of each line will be bored at an initial spacing of thirty feet. The holes will be 1/2 to 1 inch in diameter and 12 to 18 inches deep. Holes will be stabilized and identified by inserting small numbered sticks. Significant readings will be taped to the stick and recorded in data logs.

If no significant leaks were to be found using this strategy, then additional boreholes would be drilled to reduce the spacing to 15 ft. along the entire line length. Detailed monitoring would be continued using all sampling holes. ACOUSTIC EMISSION (AE) TESTING Acoustic emission testing provides additional detection and pinpointing capability. The planned testing strategy is similar to that for tracer testing. Two levels of instrumentation will be used for detection: • Portable Acoustic Emission Leak Gun provides the most sensitive and reliable leak detection possible in a small, hand -held, battery- operated unit • NDE Environmental Corporation's Acoustic Leak /Failure Detection System (ALFDS) - state -of- the -art acoustic emission sensors spectrum analyzers, together with real - time computer data reduction system, allows correction of data for background noise and attenuation. Leak location is calculated from leak signatures at all accessible connections to the pipeline. The portable AE gun will be used for initial rapid survey of "high risk" areas, "listening" through the boreholes, as well as at all accessible fittings to the pipeline. After initial survey, the gun will be used to provide detailed monitoring of the remaining boreholes, augmenting the tracer detection technique. The NDE ALFDS will be mounted in the NDE Test Van. Background and attenuation measurements will be taken prior to pressurizing each line section. once the line section is up to maximum pressure of about 15 psig, acoustic emission spectra will be measured at each accessible fitting. These will be analyzed and compared on site to provide assessment of likely leak locations. • Page Three Jeff Staneart, P.E. 12 December 1989 Y X4L4`f3 The following tasks are identified, scheduled and planned: 1.

Should such extensive testing be required, or other contingencies occur, much more labor will be expended. However, we have estimated full performance within reason, and can perform as stated with a not to exceed price of $25,646. The design test strategy is to locate major leaks early using efficient, reliable tools. Assurance of tightness in other areas is provided by null indications of sensitive instrumentation with sampling at 30 ft. intervals. Cost control will be maintained throughout the project by discussion with the City of Newport Beach Project Engineer at all decision points. The work has been planned, scheduled and estimated based on the following conditions and assumptions: (1) The City Utilities Department will drain both pipeline sections of water Page Six NDE Jeff Staneart, P.E. P, 12 December 1989 (2) Pipeline fittings at both ends of each section are accessible for pressurizing with the Helium gas mixture (3) Ground surface above the line is entirely accessible for drilling small diameter holes (12 to 18 in. deep) into the soil for tracer gas sampling (4) Testing operations may require working long hours into the night because of time required to fill the line and allow for Helium tracer to rise through the soil (5) Cost estimate does not include extensive labor to break frozen pipe fittings, excavate identified leak areas, make repairs to the lines, or retest lines after repair We trust that the approach, plan of work tasks, schedule and estimated costs as described meet your approval. If it is urgent, we could start work within four or five days of the go- ahead. Please call us about any questions or comments. We look forward to meeting your leak pinpointing needs.
