Florida Keys Aqueduct Authority Request for Proposals Project No. 7061518AC

The Florida Keys Aqueduct Authority (FKAA) is seeking Proposals from qualified professional firms to provide expertise and professional services for design, bid package development and construction phase services for repair and improvement of water transmission main cathodic protection (CP) systems.

INTRODUCTION AND BACKGROUND INFORMATION The FKAA is a political subdivision of the State of Florida, established by Special Act, Ch. 76-441, as amended, for purposes of obtaining, supplying and distributing potable water to the Florida Keys. Potable water is primarily produced by the FKAA at the J. Robert Dean Water Treatment Plant, located in Florida City, and transported alongside the Overseas Highway to the FKAA’s customers through approximately 187 miles of water transmission main, crossing 43 bridges, and distributed through approximately 690 miles of smaller-diameter piping. The transmission main ranges in size from 36 inches leaving the water treatment plant in Florida City to 18 inches at the end of the system in Key West. There is an additional section of 12- to 16-inch piping from Key Largo northward to Ocean Reef.

The FKAA maintains an extensive array of cathodic protection (CP) systems for corrosion control of buried sections of steel water transmission main and submerged interior surfaces of steel water storage tanks. The CP systems are located throughout the Florida Keys and have proven essential for reliable delivery of potable water in the corrosive marine environment.

The FKAA operates its CP systems on a continuous basis and periodically monitors each system. Monitoring by FKAA forces is done annually, and engineering evaluations of the CP facilities are contracted when the need arises. The most recent engineering evaluation was completed by CH2M HILL Engineers, Inc. (CH2M) in August 2017. This evaluation provided a thorough understanding of the condition of the FKAA’s CP facilities prior to the arrival of Hurricane Irma in September 2017 and included recommended CP system improvements. The draft Technical Memorandum (Tech Memo), Assessment of Transmission Main Cathodic Protection Systems is included as Exhibit A.

In December 2017, the FKAA surveyed its CP systems to assess conditions after Hurricane Irma. Results indicated that extensive damage and destruction of many facilities had occurred due to storm surge, high winds, and debris cleanup by heavy equipment. CH2M reviewed the results of the FKAA’s field survey and developed Tech Memo, FKAA Cathodic Protection – Restoration of Facilities Damaged or Destroyed by Hurricane Irma is included as Exhibit B.

SECTION 1 Introduction

This Technical Memorandum presents the results of an assessment of certain cathodic protection (CP) systems for corrosion control of buried steel water transmission mains operated by the Florida Keys Aqueduct Authority (FKAA). The assessment was the Predesign Phase of FKAA Project 1511-17. The FKAA will review the results and may elect to proceed with design of improvements for CP systems. CH2M services for the project were authorized by Contract CH6-17. The assessment included inspection, testing, and evaluation of designated CP facilities to assess their condition and identify needs for restoration or improvement. The approach and test methods used for the assessment are described in Section 2. Field investigations were conducted by CH2M with assistance from FKAA electricians and pipeline operators during June-August 2017. The field investigations were completed prior to Hurricane Irma, and any hurricane damage to facilities is not reflected in this document. The FKAA facilities included in the project are described below. The locations and types of CP facilities are identified on the FKAA’s Pictometry software. 1.1 Bridge Crossings There are 42 active bridge crossings in the Overseas Highway (US 1) along the Florida Keys. The scope of this project included 39 bridges where the steel transmission main is installed on the bridge over the water, and the pipeline is buried in the earth adjacent to the channel. The configuration of the buried pipeline can be different on each side of the channel, so there were 78 separate sections of steel pipeline evaluated for CP in this project. Most steel transmission main bridge crossings are 24-inches (in) diameter, with several 30-in crossings, two 36-in crossings, and one 18-in crossing. The length of buried steel pipeline ranges from 6 feet to several hundred feet or more before the transmission main transitions to ductile iron pipe. Galvanic anodes and test stations were originally installed to provide CP for buried pipelines at the crossings when the bridges were built around 1980. The CP facilities were periodically monitored, and an assessment in 1998 led to the installation of new anodes and test stations at some bridge crossings under Phase 1 CP Improvements in 2003. The typical useful life of an anode is 15 years, and the FKAA recognized that another assessment of the facilities was warranted in 2017. Results of the CP evaluation of bridge crossings in 2017 are described in Section 3. 1.2 Key West The steel transmission main on Key West consists of approximately 8,000 feet of 18-in pipeline and a few feet of 12-in pipeline. The CP system has 5 impressed current CP stations and 7 test stations, all of which are in the streets of Key West. The CP facilities were constructed in 2008, under Phase 2 CP Improvements. There were several known issues with CP facilities in Key West. Access is challenging due to heavy traffic and limited space. In 2016, a CP rectifier station was damaged and required repair. One of the test stations was covered with street pavement. The steel transmission main was known to have inadequate CP near the Key West Pump Station, and this was attributed to incomplete electrical isolation of the steel main near the Monroe County Courthouse. A corrosion leak recently occurred in the pipeline on Request for Proposal EXHIBIT A SECTION 1 – INTRODUCTION

Eaton Street, illustrating the need for an assessment of CP facilities in Key West. Results of the CP evaluation in Key West in 2017 are described in Section 4. 1.3 Marathon There are 5 active sections of 24- and 30-in diameter steel pipeline on Marathon, including sections at Seven Mile Bridge and Vaca Cut. The 18-in steel transmission main has been almost entirely deactivated on Marathon, but its CP system provided protection for some active sections of steel transmission main. The FKAA recognized that an assessment of CP was needed to assure continued CP of the 30-in steel main with the 18-in main deactivated. The section of 24-in steel main on Knight’s Key at Seven Mile Bridge had CP from a galvanic anode system installed during Phase 1 CP Improvements in 2003. Recent construction of landscaping improvements cut the anode wires and eliminated CP of the pipeline. The FKAA recognized that an assessment was needed to determine the best way to provide CP for the steel pipeline under present conditions on Knight’s Key. Results of the CP evaluation on Marathon in 2017 are described in Section 5. 1.4 The 18-Mile Stretch MM 121-122 There are two sections of 36-in steel transmission main in the 18-Mile Stretch. One section has an approximate length of 10 miles, from Mile Marker (MM) 106 to 116.5, and it is protected by an impressed current system constructed in 2008. The FKAA monitors the CP system, and it was excluded from the scope of this project. The other section of steel transmission main in the 18-Mile Stretch is located at MM 121-122 and is approximately 3,900 feet in length. CP was originally provided by sacrificial magnesium anodes and 12 test stations installed when the pipeline was constructed in about 1980. In 2008, new anodes were installed and the test stations were modified. Subsequent highway construction destroyed most of the CP facilities. The FKAA repaired several test stations and installed additional anodes in the last few years, but recognized that an assessment of the CP facilities was needed. Results of the CP evaluation at MM 121-122 in 2017 are described in Section 6. 1.5 Recommended Improvements After the field investigations were completed, a list of CP deficiencies was developed with corresponding recommended improvements or corrective actions for each pipeline. Recommended improvements to restore CP at bridge crossings consist mainly of galvanic anodes and test stations. However, other types of work are also required. Recommended improvements and their importance are described in Sections 7 and 8. 1.6 Construction Cost Estimate A preliminary construction cost opinion was prepared for the recommended CP Improvements. This is a Class 4 Estimate as described by AACE International Recommended Practice 18R-97. The cost opinion is preliminary because it is based on elements of work that are anticipated for construction but have not yet been designed. Estimated construction costs are described in Section 8. 1.7 Cathodic Protection CP is an electrochemical method of reducing or preventing corrosion of a metal surface by making it cathodic to its environment. This is accomplished by providing electrical direct current to the metal

surface from expendable or inert materials through the environment with sufficient intensity to suppress any electrochemical corrosion activity that is occurring on the metal surface. The two methods of applying CP are galvanic anodes and impressed current systems. The FKAA’s CP facilities include both types of systems, described in more detail below. CP of pipeline exterior (soil-side) surfaces requires CP facilities in the earth. Exterior CP does not control corrosion that may occur on internal (water-side) surfaces of the pipeline. CP is one of the most widely used forms of corrosion control. It is adaptable to many forms of metallic corrosion, and, when properly used, provides highly effective and economical protection from corrosion damage. The amount of protection applied can be regulated by the specific requirements of the site. The degree of protection applied and obtained can be measured. 1.7.1 Galvanic Anodes Galvanic anodes are made of active metals, usually zinc or magnesium. When an anode is connected to a buried or submerged steel pipeline, electrochemical oxidation (corrosion) occurs at the anode, while electrochemical reduction (protection) occurs at the steel cathode. The anode is attached by wire directly to the pipe or through a junction box called a test station. Figure 1-1 illustrates the typical arrangement of galvanic anodes and test stations constructed during Phase 1 for CP of the steel transmission mains at bridge crossings. Most of the bridge crossings have or had galvanic anodes, which are more efficient for CP of relatively short pipelines. 1.7.2 Impressed Current Impressed current CP systems use an external power source, which is usually a rectifier that converts alternating current (AC) electricity to direct current (DC). The DC positive terminal is electrically connected to a group of anodes called a ground bed. The DC negative terminal is electrically connected to the steel pipe to make it the cathode. The current is adjusted and monitored at the rectifier. Test stations are used to measure the CP effect along the connected pipeline. Impressed current CP stations were constructed during Phase 2 for CP of the 18-in steel transmission main. Some sections of 24- through 36-in steel transmission mains also have CP by impressed current. Figure 1-2 illustrates the arrangement of impressed current CP stations for buried steel transmission mains.

SECTION 2 Test Methods

This section describes the approach and methods of field investigation and testing of CP on buried steel transmission mains. The field tests were essentially electrical in nature and were based on established industry practices for CP testing. Selected photographs of the pipelines and test equipment follow the text in this section. The CP facilities included in the scope of work were visited for inspection and testing. Each site was visually examined to find existing test stations and assess their condition. Test stations are post- mounted or flush-mounted boxes containing wires that are connected to the pipe. Other visible pipeline features, such as flexible couplings at bridge crossings, were also noted. At each test station, the wires were inspected and tested to identify their function. A GPS coordinate was collected for each test station that was not previously documented during Phase 1 and Phase 2 CP Improvements. 2.1 Pipe-to-Soil Potential Measurement The pipe-to-soil potential (PSP) was measured at test stations using an MC Miller LC-4 digital electronic voltmeter and a copper sulfate reference electrode (CSE). If a test station was not found at a bridge crossing, direct contact was made to the steel main on the bridge for measurement of PSP. Values of PSP that are -850 millivolts (mV) or more negative to a CSE indicate adequate CP for buried steel. PSP values in the range of -650 to -850 mV CSE indicate marginal protection. PSP values -650 mV CSE or less negative indicate that CP is not adequate for buried steel. The assessment of CP is most accurate when the PSP is measured with the CP momentarily turned OFF so that the steel is tested in a ‘polarized’ condition. If the CP source cannot be turned OFF, the PSP measurement must be made with the CP source ON, and the assessment of CP is made with the knowledge that the assessment may be less accurate than if would be if the CP could be turned OFF for testing. Ductile iron pipe that is used for most of the buried transmission main does not, by design, have CP under most conditions, and PSP values that are -650 mV CSE or less negative are considered normal. Ductile iron pipe with PSP more negative than -650 mV CSE indicates that it has CP or is in metallic contact with a steel pipeline that has CP. At transitions between ductile iron and steel pipelines, connections were made with transition couplings or, less commonly, insulated flanged joints. Both types of connections were intended to provide electrical isolation between the two pipe materials. Test stations at the transitions were installed with test leads to the steel and ductile iron pipes so that the PSP of both materials could be measured. The difference in PSP between steel and ductile iron pipe provides an indication of the quality of electrical isolation at the transition between the two pipe materials. 2.2 Current Measurement Some test stations have wires from anodes or other pipelines that carry an electrical current for CP purposes. Where this configuration existed, the current was measured using a shunt. Shunts are calibrated resistors that have low values of resistance, such as 0.01 ohm. Measurement of voltage drop across the shunt indicates the current by Ohm’s Law. For example, 1.0 mV measured across a 0.01-ohm shunt indicates a current of 100 mA. Some test stations had shunts installed in anode wire connections, and those shunts were used to measure the anode current to the pipeline. Where shunts were not installed, the wires were temporarily

Request for Proposal EXHIBIT A SECTION 2 – TEST METHODS

disconnected and the current was measured with a portable shunt and voltmeter. All other current measurements were also made using a portable shunt and voltmeter. 2.3 Current Requirement If the measured pipe-to-soil potential indicated that CP was inadequate, a temporary electrical current was applied to determine the ‘current requirement’ of the section of pipeline. The current requirement indicates the amount of direct current (DC) electricity required for CP of the tested pipeline. The magnitude of the current requirement, relative to the length of the tested pipeline, also provides an indication of the quality of electrical isolation of the steel pipeline from the bridge or from adjacent buried ductile iron pipe. The temporary current was applied to the pipe using a battery and a ground such as a metallic cable temporarily submerged in the channel near the bridge. The temporary current was measured and cycled on and off while PSP measurements were made at the test points. The amount of applied current required to change the PSP to -850 mV CSE or more negative is the fundamental design parameter for CP of the tested pipeline. Where test leads to the ductile iron were present at test stations, the PSP of the ductile iron was measured while current was temporarily applied to the steel pipeline. The change in PSP with the test current OFF and ON provides another indication of the quality of electrical isolation between the steel and ductile iron. This test was helpful in situations where the PSP values of steel and ductile iron pipes were similar in their as-found condition, such as when CP of the steel was not adequate. 2.4 Electronic Location A Tinker & Rasor ‘Model PD Pipe and Cable Locator’ was used to electronically locate buried steel transmission mains and assess the length and electrical features of the pipelines. This instrument is an accurate locator or tracer of coated metallic pipelines that are electrically continuous across pipe joints. The Tinker & Rasor Model PD is commonly called a ‘short’ locator. A ‘short’ is a point of unintended electrical conductivity between a buried metallic pipeline and some other metallic pipeline or structure. The short locator can also indicate points where electrical conductivity ends, such as at an insulated joint for electrical isolation of a pipeline. The short locator can be used on electrical cables as well as on pipelines, and for submerged or buried environments. The Tinker & Rasor Model PD uses a separate transmitter and a receiver. One terminal of the transmitter is electrically connected to the pipeline, and the other terminal is connected to a separate, low-resistance grounding electrode such as a metal object submerged in seawater. The transmitter produces an audio frequency AC signal that passes through earth and water between the pipe and the grounding electrode. The receiver is placed over the area where the pipe will be located or traced. As the receiver is moved back and forth in a horizontal plane, a sharp null (silence) occurs in the received signal and indicates the exact location of the pipeline directly below the receiver. A well-coated pipeline can be followed for a considerable distance by this method. A short is indicated when the location of the null departs from the pipeline by another conductive path. Most shorts also reduce the strength of the signal and sharpness of the null over the pipeline on the side of the short furthest from the transmitter. This is due to the energy drained from the pipeline by the short. The short has the same adverse effect on CP of the pipeline. Locating a short allows correction of the condition and improved CP after the short is corrected or ‘cleared.’ Electrical isolation of the traced pipeline is indicated where the signal cannot be detected beyond a certain point, and there is not a short somewhere else along the pipeline. Electrical isolation that is weak or semi-conductive will usually cause a gradual decay in the strength of the signal and null as the

2-2 CH2M HILL INC. 694334.03.30.01 Request for Proposal EXHIBIT A SECTION 2 – TEST METHODS receiver is moved along the pipeline in the affected area. The pattern of decay is determined by several factors, including the weakness of isolation, the quality of the protective coating, and the conductivity of the earth or water around the pipeline. The differences between the Tinker & Rasor Model PD and most other conductive pipe locators are the frequency of the signal, the power of the transmitter, and the sensitivity of the receiver. Other locators are generally unsuitable for location of shorts and electrical isolation. 2.5 Photographs Selected photographs follow.

SECTION 3 Bridge Crossings

This section covers bridge crossings, where the transmission main is installed on the highway bridge over the water. The scope of the project included 39 bridge crossings from Cow Key Channel to Adams Waterway. Bridge crossings that were not included in the project were: Jewfish Creek flyover; Salt Run Bridge in Key West; and an unnamed bridge on North Roosevelt Boulevard near Key West City Hall. At Snake Creek, the steel transmission main has a subaqueous crossing and is not installed on the bridge. 3.1 Background All the bridge crossing pipelines are constructed from steel pipe. The pipeline is exposed on the bridge except in a few locations where it is within a hollow core concrete bridge structure. The steel pipeline is buried in the earth adjacent to the channel. The steel pipe is coated and is intended to be electrically isolated from the bridge and from the ductile iron transmission main. The buried pipeline on each side of the channel is electrically independent from the pipeline on the other side, so there are 78 discrete pipelines for CP purposes. The steel pipelines are buried for varying distances on each side of the bridges before connecting to ductile iron pipe. The diameter of the steel transmission main is 24-in or 30-in at most bridge crossings. Two crossings are 36-in diameter, and one crossing is 18-in diameter. The length of buried steel pipeline ranges from 6 feet to several hundred feet or more before the transmission main transitions to ductile iron pipe. Galvanic anodes and test stations for pipeline CP were originally installed at the crossings around 1980, when the bridges were built. The facilities were periodically monitored, and an assessment in 1998 led to the installation of new anodes and test stations at some bridge crossings under Phase 1 CP Improvements in 2003. In 2016, field tests were made at a few bridge crossings, and results indicated that CP was deficient at some of the tested locations. 3.2 2017 Inspection and Testing In 2017, all 39 bridge crossings from Cow Key Channel (MM 4.2) to Adams Waterway (MM 103.5) were visited for observation and testing of CP facilities on both sides of the channels. The methods of investigation and testing are described in the Test Methods section of this report. In summary, each site was examined to identify existing test stations and their condition. GPS coordinates were recorded for each test station that was found but not previously documented with GPS. The PSP was measured at each test station to assess the adequacy of CP and to identify test station wires. Where test stations were absent, direct metallic contact was made to the exposed steel pipeline for measurement of PSP. If the PSP indicated that CP was inadequate, a temporary test current was applied to the main to determine the cathodic current requirement for CP. An electronic locator was used at most locations to trace the buried steel pipeline and determine the locations of transition couplings and insulated flanges that provided electrical isolation. Steel pipelines without effective electrical isolation from the bridge or adjacent buried ductile iron pipe were identified based on the current requirement and the results of electronic tracing of the pipeline. Some of the bridge crossings also had a crossing under US 1 or an arterial road at some distance from the bridge. These ‘road crossings’ are believed to be steel pipe at all locations. An effort was made identify and, where possible, test the CP of the crossing pipelines.

Only 23 of 78 sections of steel transmission main had adequate CP at bridge crossings. A total of 44 sections had essentially no CP, and 11 sections had marginal CP. Details are presented in Appendix A, which includes test results in Table A-1, followed by descriptions of the history and findings at tested locations. Results indicate that CP is adequate for only 27 percent of the steel pipeline sections west of Marathon, and for only 35 percent east of Marathon. Considering that there are 26 bridges west of Marathon and 13 bridges east of Marathon, there are more crossing pipelines at risk for corrosion in the Lower Keys. Test results suggest that most of the original anodes installed around 1980 have been consumed. Many of the original test stations have been destroyed or damaged by other construction or deteriorated from exposure to the elements. Some of the anodes and test stations installed in 2003 are in similar condition but others are intact and functional. An unexpected finding was the length of the buried steel transmission mains at numerous bridge crossings. Field tests showed that some of the steel pipelines are longer than previously thought. Islands that appear to have significantly longer lengths of buried steel pipeline include: Park, Ohio, Missouri, Indian, Indian Key Fill, Tea Table, and Lower Matecumbe Keys. The total length of pipelines that are known or strongly indicated as being steel by test results was 24,701 feet or 4.7 miles. There may be even longer lengths of steel pipelines in certain areas as noted in the detailed descriptions of the bridge crossings. It will be important to verify the lengths of steel pipelines at all locations so that CP can be provided for effective corrosion control. 3.4 Road Crossings Additional lengths of 24- to 36-in steel transmission main may exist at buried crossings of US 1. There appear to be 13 crossings of US 1 by 24- to 36-in transmission main as listed in Table A-2 of Appendix A. Several of these are known to have steel carrier pipe and casing based on work completed during Phase 1 and 2 CP Improvements. There are also other arterial road crossings with steel pipe in addition to the one shown in the table.

3-2 CH2M HILL INC. 694334.03.30.01 Request for Proposal EXHIBIT A SECTION 3 – BRIDGE CROSSINGS

CP tests were conducted on 4 crossings of US 1 and one arterial road crossing where the transmission main pipe material is steel. Test results indicated that CP was adequate in most cases and marginal at worst. There are 3 additional crossings of US 1 that were not tested but are known to have CP by impressed current from systems constructed in Phase 2 CP Improvements, and these are monitored by the FKAA. There is no information on the transmission main pipe material at 5 other crossings of US 1. They are listed in Table A-2 of Appendix A. Considering that steel pipe is known to exist at several other crossings of US 1, it seems possible that these 5 crossings may also have been constructed from steel pipe. Steel pipe would have had advantages in construction of road crossings, such as the relatively compact size of mitered bends for directional changes in the pipeline and thrust restraint provided by welded joints. It will be important to identify the pipe material at the other crossings and to determine the lengths of steel pipelines so that CP can be provided for effective corrosion control. 3.5 Recommended CP Improvements Recommended CP improvements for the bridges and road crossings are presented in Section 7. Restoration of CP at bridge crossings will require primarily the installation of galvanic anodes and test stations. However, other types of work will also be required at certain locations. It is also recommended that the FKAA verify the pipe material and length of sections of transmission main that are suspected to be constructed of steel pipe, so that CP can be provided for effective corrosion control of all steel pipelines. Similarly, the transmission main pipe material should be identified at 5 crossings of US 1 where the material is unknown, so that CP can be provided for all steel pipelines.

SECTION 4 Key West

This section covers the 18-in buried steel transmission main on Key West. The pipeline extends from the intersection of Eisenhower Drive and North Roosevelt Boulevard to the Key West Pump Station (KWPS). 4.1 Background The 18-in steel transmission main on Key West is nearly 8,000 feet in length. It transitions to PVC pipe at the intersection of Eisenhower Drive and North Roosevelt Boulevard. The 18-in main reduces to 12-in steel pipe near a valve on Whitehead Street at the Monroe County Courthouse. The 12-in steel pipe is thought to transition to cast iron pipe at the valve. The 12-in buried pipeline continues for approximately 240 feet through the Courthouse parking lot to KWPS. CP facilities for the steel pipeline were constructed in 2008 during Phase 2 CP Improvements. The CP facilities consist of 5 impressed current (rectifier) stations and 7 test stations. All CP facilities are in the streets of Key West, where access is challenging due to heavy traffic and limited space. During Phase 2, the construction contractor tested the 18-in pipeline for electrical continuity and installed joint bonds at 17 buried flexible couplings. All but one of the bonded joints were in Whitehead Street. The contractor’s commissioning report indicated that the 12-in and 18-in pipelines were electrically continuous to a test station in the Courthouse parking lot, but not from the test station to KWPS. The report stated that CP was not attained on the 12-in pipeline near KWPS and attributed this condition to incomplete electrical isolation. A magnesium anode was installed at the test station on the 12-in pipeline at the KWPS to supplement CP provided by the impressed current system. The FKAA has periodically monitored the CP system since it was installed in 2008. In 2016, the rectifier station near the Post Office was found damaged and out of service due to impact by a vehicle or equipment. The station was repaired and returned to service. In 2017, a leak occurred on the 18-in pipeline at 400A Eaton Street, which is about 50 feet north of Whitehead Street and 200 feet from the CP station at the Post Office. Inspection of the excavated pipeline by the FKAA indicated that external corrosion was the cause of the leak, which was subsequently repaired. The FKAA took the opportunity provided by the excavation to install a test station on the pipeline at that location. This action provided an 8th test station on the steel pipeline. The locations of CP facilities on the 18-in steel transmission main in Key West are shown in Figure B-1 in Appendix B. 4.2 2017 Inspection and Testing Inspection and testing of the rectifier stations indicated that all 5 of them were operating normally and were in good condition. The oil coolant was light amber in color, which is a normal discoloration compared to new oil. The rectifiers were tested to verify proper operation. Test results are shown in Table 4-1 (next page). All rectifiers except the one at the Post Office were found operating at the same tap settings and approximately the same current outputs as they were when commissioned after construction. Inspection showed that the tap setting of the Post Office rectifier was reduced from its original setting, and tests showed that the current output was 600 mA compared to 3800 mA as commissioned. The tap setting may have been changed when the station was damaged and repaired in 2016. Tests of PSP at nearby test stations indicated that CP levels were low. The taps were reset to the commissioned settings, which increased the current output as expected.

The PSP of the steel pipeline was measured at all test stations and CP stations. The FKAA provided traffic control for access to the test stations on Eaton Street. Test results are presented in Appendix B, which includes test data in Table B-1 and a chart of the data in Figure B-2. Test results indicated that CP was adequate at all locations tested, except those on the pipeline within about 2,500 feet of KWPS and including the location of the recent corrosion leak. Experience suggested that there were 3 possible causes for this condition: A ‘short’ or unintended conductive connection; lack of electrical isolation; or failure of a joint bond and loss of continuity along the pipeline. Extensive diagnostic tests were conducted to try to identify the reason for the apparent inadequate CP of the 2,500 feet of steel pipeline near the KWPS. The electrical continuity of the pipeline was tested, and it was found continuous between the test stations at 400A Eaton Street and at Fleming Street. This indicated continuity of the pipeline through the area of the Post Office CPS. However, continuity of the pipeline did not extend to the valve on Whitehead Street or to test stations at the Courthouse or KWPS. The steel transmission main was electronically traced in both directions from the Post Office CPS. The pipeline was traced along Whitehead Street toward KWPS to a point just before the valve, suggesting that a pipe joint near the valve was not bonded or that a previous bond had failed. Electronic tracing of the pipeline from the Post Office CPS in the opposite direction (away from KWPS) along Whitehead Street showed that the signal departed from the steel pipeline at the intersection with Eaton Street. The electronic trace continued approximately 480 feet north along Whitehead Street and ended at a fire hydrant at 301 Whitehead Street. This result indicated that a ‘short’ to the steel transmission main exists at the intersection and extends along Whitehead Street. A record drawing provided by the FKAA for this location (see Appendix B) suggested that a 12-in ductile iron distribution watermain was apparently the metallic path followed by the electronic signal. Considering the age of the street, it seems possible that the traced pipeline ‘short’ on Whitehead Street could be cast iron with metallic joints and that it is directly connected to the 18-in steel main in the intersection. The record drawing also shows other buried metallic piping in the intersection, and one or more of these pipelines could be shorted to the steel transmission main at this location.

4-2 CH2M HILL INC. 694334.03.30.01 Request for Proposal EXHIBIT A SECTION 4 – KEY WEST 4.3 Conclusions Test results indicated that the steel transmission main in Key West had PSP of -850 mV CSE or more negative, indicating adequate CP, from Eisenhower and North Roosevelt to Eaton Street at Peacon Lane. The length of protected pipeline is approximately 5,600 feet. However, the steel transmission main had PSP less negative than -850 mV CSE, indicating inadequate CP, from around 620 Eaton Street to the KWPS. The length of unprotected pipeline is approximately 2,500 feet and includes the 12-in and 18-in pipelines. The area of inadequate CP is believed to result from a ‘short’ between the 18-in pipeline and one or more metallic distribution mains at the intersection of Eaton and Whitehead Streets. The shorted pipeline drains CP current from the steel pipeline, causing reduced protection of the steel near the short. The recent leak at 400A Eaton Street, which is near the location of the short, was probably a result of inadequate CP. Correction of the CP system deficiencies along Whitehead Street would require the following measures: • Excavation of the pipeline in the intersection of Eaton and Whitehead Streets to locate and clear shorts by installing insulated flexible couplings or flange insulating kits and test stations at the connections found. • Excavation of the valve and adjacent pipeline on Whitehead Street near the Courthouse to bond the joints and install a test station. • Excavation of the 12-in pipeline between the KWPS and the valve on Whitehead Street to locate and bond pipe joints that are not electrically continuous, and to select the point where electrical isolation will be established. In addition, the 3 existing test stations on Eaton Street should be relocated from their present locations in the street to convenient points behind the curb and out of the street. This action will eliminate the need for traffic control during testing and thereby improve safety and encourage monitoring. After this work has been completed, it will be necessary to measure the PSP at all test points and adjust the current outputs from the CP stations if necessary based on the test results. Alternatively, the FKAA could consider replacement of the transmission main with a suitable pipe material between KWPS and Eaton Street. The point of connection to the 18-in main should be located east of the recent corrosion leak to ensure that the corroded pipe is included in the replacement. The length of pipeline would be approximately 1,200 feet including the 12-in pipeline to KWPS. Consideration was reportedly given to replacing the 12-in pipeline during KWPS improvements in 2005, but it was not replaced. Pipeline replacement would require excavation across the Courthouse parking lot or selection of another route around it.

SECTION 5 Marathon

This section covers CP of buried steel transmission mains on Marathon (MM 47-53). There are 5 active sections of steel transmission main on Marathon. One section consists of approximately 1,150 feet of 24-in pipeline on Knight’s Key adjacent to the Seven Mile Bridge. Another section consists of 545 feet of 30-in pipeline that crosses US 1 at Aviation Boulevard. Another section consists of 551 feet of 30-in pipeline near Vaca Cut. The remaining 2 sections are short lengths of 24-in pipeline that connect Marathon Booster Pump Station to the 18-in steel transmission main and the 30-in ductile iron transmission main. The 18-in steel transmission main on Marathon has been deactivated, but its CP system provides protection for certain active sections of steel transmission main. The deactivated steel pipeline may also have residual value as a conduit for other potential uses, and continued operation of the CP system would help maintain integrity of the pipeline. 5.1 Background The 18-in steel transmission main on Marathon is approximately 30,000 feet in length. Before the pipeline was deactivated, it was connected to the Marathon Booster Pump Station, which is located at MM 48.7 or about 8,500 feet from the west end of Marathon. CP facilities for the 18-in pipeline were constructed in 2008 during Phase 2 CP Improvements. They consisted of 7 impressed current (rectifier) stations and numerous test stations. There were also magnesium anode anodes installed on the 30-in steel pipelines that connect Marathon Booster Pump Station to the 18-in and 30-in water transmission mains. The 30-in steel pipeline crossing US 1 at Aviation Boulevard (MM 51.0) was electrically connected to the 18-in pipeline with a bond wire for CP of the 30-in pipeline. The FKAA has periodically monitored the CP system since it was installed in 2008. Deactivation of the 18-in steel transmission main has been done in stages. Along with other events, deactivation has affected the CP system on Marathon as described below. 5.2 2017 Inspection and Testing 5.2.1 Knight’s Key to Marathon Booster Pump Station In 2017, the FKAA cut and capped the 18-in main at Knight’s Key (MM 47.0), but the portion of the pipeline that crosses US 1 was left active to provide water service to Pigeon Key. The active portion of the 18-in main is connected to the 24-in main, which reduces from the 30-in main at Valve Vault S78, located east of 7-Mile Bridge. The FKAA’s work on the 18-in main at Knight’s Key occurred at about the same time as other construction activity cut off CP from 1,153 feet of 24-in steel pipeline on the east side of 7-Mile Bridge. Subsequent activities related to CP are discussed under Bridge Crossings. Test results are presented in Table C-1 in Appendix C. In summary, the impressed current station at Knight’s Key is now used to provide CP for the 24-in steel pipeline to the bridge and for the 18-in steel pipeline crossing US 1. That rectifier station no longer provides CP for any of the 18-in pipeline east of Knight’s Key because the pipeline has been cut and capped. The FKAA plans to cut and cap the 18-in pipeline on the west side of Marathon Booster Pump Station. This action will result in a section of deactivated pipeline about 8,500 feet in length from the pump station to Knight’s Key. This section of pipeline has 2 impressed current stations located at 7-Mile

Marina (MM 47.0) and at the FKAA Customer Service Center (MM 48.7). These stations were inspected and tested to assess CP on the pipeline. Test results are summarized in Table 5.1. Inspection of the rectifier stations discovered that the rectifier at MM 48.7 was OFF due to a tripped secondary breaker. The breaker was reset and the station was returned to service. The rectifier stations were otherwise operating normally and were in good condition. The oil coolant was light amber in color, which is a normal discoloration compared to new oil. Table 5-1.

The results of tests made at rectifier stations and test stations are presented in Table C-2 in Appendix C. Results indicate that PSP is less negative than -850 mV CSE, indicating that CP is not adequate for the entire pipeline. It seems that the pipeline has a high cathodic current requirement that exceeds the maximum current output capacity of the rectifiers. The high current requirement is likely due to deteriorated protective coating on the pipeline or an unknown connection (short) to another buried metal pipeline or structure somewhere along the pipeline. It is possible that protection levels will improve after the FKAA cuts and caps the 18-in pipeline on the west side of Marathon Booster Pump Station. This work is expected to result in complete electrical isolation of the pipeline. If the deactivated 18-in pipeline will be preserved, tests should be conducted after completion of the pipeline work to determine if protection levels improve. 5.2.2 Marathon Booster Pump Station Other recent construction activity along US 1 has destroyed the anodes on the 30-in steel pipelines that connect Marathon Booster Pump Station to the 18-in and 30-in water transmission mains. No tests were conducted due to construction activity around existing test stations. It will be necessary to replace the anodes and conduct tests to verify that CP has been restored on the steel pipelines. 5.2.3 Marathon Booster Pump Station to Vaca Cut The easterly portion of the 18-in steel transmission main on Marathon was deactivated a few years ago, and the impressed current station at MM 53.0 was deactivated along with it. The FKAA removed the rectifier from the station and disconnected the AC power service. In 2017, the FKAA cut and capped the 18-in steel transmission main on the east side of Marathon Booster Pump Station. This action resulted in a section of deactivated pipeline about 21,800 feet in length from the pump station to Vaca Cut. This section of pipeline has 3 impressed current stations located at: 46th Street (MM 49.5); 70th Street (MM 50.9); and 100th Street (MM 52.2). These stations were inspected and tested to assess CP on the

pipeline. Test results are summarized in Table 5-2. It was noted that the rectifier station at MM 50.9 was not shown on Pictometry. Table 5-2.

Inspection and testing of the rectifier stations indicated that they were operating normally and were in good condition. The oil coolant was light amber in color, which is a normal discoloration compared to new oil. Tests made at the rectifier stations and at test stations are presented in Table C-2 in Appendix C. Results showed that the PSP was more negative than -850 mV CSE, indicating adequate CP, for the entire section of pipeline from Marathon Booster Pump Station to Vaca Cut. This includes the 30-in steel pipeline crossing US 1 at Aviation Boulevard, which has a CP bond wire connection to the 18-in pipeline. The flush-mounted test station that houses the bond wire connection was located and recovered after considerable effort by the FKAA. The search for the bond station ultimately found it buried about 1 foot deep, and it was raised to ground level and marked to aid recovery for future monitoring. There is another section of 30-in steel transmission main located near Vaca Cut. The pipeline is 551 feet in length and is connected to a section of 310 feet of buried steel pipeline west of the bridge. Both sections of steel pipeline were tested for CP as discussed in Bridge Crossings. In summary, the entire section (861 feet) of 30-in steel transmission main has galvanic anodes installed during Phases 1 and 2 CP Improvements, and tests show that PSP is more negative than -850 mV CSE, indicating adequate CP. 5.3 Conclusions Test results indicated that all tested steel sections of 24- and 30 transmission main on Marathon have PSP of -850 mV CSE or more negative, indicating adequate CP. This includes the only active section of 18-in steel main that crosses US 1 at Knight’s Key. However, the 24-in steel pipeline sections at Marathon Booster Pump Station could not be tested for CP due to other construction activity and are probably not protected due to destruction of the installed anodes by that same activity. It will be necessary to replace the anodes and conduct tests to verify that CP has been restored on the steel pipelines. The 18-in deactivated steel transmission main has adequate CP from Marathon Booster Pump Station to Vaca Cut. The CP system for this section provides CP for the 30-in steel pipeline crossing US 1 at Aviation Boulevard, which has a bond to the 18-in pipeline. It will be necessary to continue operation of the CP system on the 18-in deactivated steel transmission main to maintain protection for the 30-in steel pipeline. If the CP system for the 18-in pipeline were to be deactivated, it would be necessary to construct a new CP station to provide for the 30-in steel pipeline. Operation of the existing CP system in its present configuration can protect the 30-in steel pipeline without additional construction while maintaining the integrity of the 18-in deactivated steel pipeline at minimal cost until the CP stations reach the end of their useful life (15 to 20 years).

The 18-in deactivated steel transmission main does not have adequate CP between Marathon Booster Pump Station at the end of the pipeline at Knight’s Key. The cathodic current requirement of the pipeline exceeds the capacity of the 2 existing impressed current stations. The high current requirement is likely due to deteriorated protective coating on the pipeline or a short to another buried metal pipeline or structure. Protection may improve after the FKAA cuts and caps the 18-in pipeline on the west side of Marathon Booster Pump Station, because the work will result in complete electrical isolation of the pipeline. If the FKAA (or another party) desires to maintain the integrity of this portion of the deactivated 18-in main, then tests should be conducted after completion of the pipeline work to determine if protection levels improve. Additional impressed current stations would be required to protect the pipeline if isolation does not improve the situation and complete protection of this section of steel pipeline is desired.

SECTION 6 The 18- Mile Stretch MM 121 – 122

This section covers the section of 36-in buried steel transmission main at MM 121-122 in the 18-Mile Stretch. The transmission main is in the Everglades on the Bay side of US 1. The length of the steel pipeline is 3,900 feet. 6.1 Background Construction records indicate that the steel pipeline section at MM 121-122 was protected by magnesium anodes when it was installed around 1982. The pipeline was connected to ductile iron pipe with transition couplings. Test stations were installed at the transition couplings and at intervals of approximately 360 feet along the steel pipeline. The test stations at the transitions had wires connected to both the ductile iron and steel pipes to permit testing of the dielectric isolation provided by the couplings. At each test station, a 50-pound magnesium anode was installed and connected to the steel pipeline through wires and a shunt on the test station terminal board. A total of 12 test stations were originally installed and had reference numbers 7A1 through 7A12, with the first number and letter indicating the pipeline construction contract. Records indicate that the total current output of the anodes was approximately 400 mA when they were new in 1982, and that the PSP was around -1300 mV CSE at all stations. The test stations were periodically monitored for pipe-to-soil potential and anode current output. Around 2005, other construction work began to affect the test stations. A chain link fence was erected along the Everglades. During Phase 2 CP Improvements in 2008, the test stations were moved outside the fence and converted from post-mount to flush-mount, and a new anode was installed at each station. Then a highway paving and improvement project was constructed that destroyed most of the test stations. In 2012, the FKAA found severed wires at 5 of the 12 test station locations. The recovered wires were from test stations on the northerly end of the steel section. The FKAA extended the test wires to post- mounted stations between the Everglades fence and the highway. The FKAA and CH2M HILL tested the stations to identify wires, and identified the approximate location of the southernmost test station at the ductile iron transition. The FKAA subsequently found severed wires at the southernmost test station and at the adjacent test station. The test wires were extended to post-mounted stations between the Everglades fence and the highway. This work was completed around 2015. Subsequent tests by the FKAA at the 7 recovered test stations suggested that the steel pipeline had adequate CP except at the northerly end of the line. 6.2 2017 Inspection and Testing The 7 test stations on this section of steel pipeline were inspected and tested in 2017. Inspection showed that the wiring arrangements differ among stations. Some stations appear to have more wires than the original stations, and the wire insulation colors vary. All these variations have the potential to create confusion, especially since only a few wires are labeled. Tests showed that most of the wires are functional. However, the test wires to the pipe in the station at MM 121.49 are suspect, and there is only 1 functional wire (there should be 2 wires) to the ductile iron pipe at the northerly and southerly transitions. There are also newer and older anodes connected in some stations, and the older ones are mostly depleted.

Test results are summarized in Table 6-1 (next page) and in Table D-1 of Appendix D. Results showed that the PSP of the steel pipeline ranged from -846 to -1066 mV CSE with the anodes connected (‘ON’) at individual test stations and from -795 to -950 mV CSE disconnected (‘OFF’). The pipe test wires in the station at MM 121.49 are suspect, because they had a highly negative potential without the anode connected and the anode had no measurable current output. The current outputs of the other anodes ranged from 24 to 39 mA and totaled 169 mA. Table 6-1. Cathodic Protection Test Results MM 121-122 36-in Steel Transmission Main

The PSP of the ductile iron at the southerly transition indicates that it is electrically isolated from the steel pipeline. However, the ductile iron appears to be shorted to the steel at the northerly transition. These conclusions regarding electrical isolation assume that the single test wire to the ductile iron is functional at both test stations. 6.3 Conclusions Test results indicated that the steel pipeline at MM 121-122 has PSP of -850 mV CSE or more negative at all locations except at the transitions, and particularly at the northerly transition where electrical isolation from ductile iron pipe is incomplete. Taken at face value, these PSP values would suggest adequate CP. However, there is reason for concern about the level of protection which is significantly lower than it was when the pipeline was new. The total anode current is about 42 percent of original; and the PSP is about 300 mV more positive. In addition, there is a significant gap in the spacing of anodes between the test stations at MM 121.15 and 121.49. There is the potential for microbial-induced corrosion or MIC in the Everglades environment in which the pipeline is installed. Environments characterized by decomposition of organic matter present elevated risks of MIC and warrant higher levels of CP. This can be accomplished by increasing the cathodic current by increasing the number of anodes. A current requirement test was conducted on the pipeline, and results indicated that an additional 400 mA of current would boost CP to approximately its original level. This amount of current could be provided by 2 additional magnesium anodes at each existing test station, for a total of 14 anodes. The anodes could be connected in the test stations to avoid excavation of the pipeline in the high groundwater conditions that exist at the site. These improvements are recommended for the section of steel transmission main at MM 121-122.

SECTION 7 Recommended Improvements

This section presents recommended CP improvements for the FKAA pipelines included in the project. A detailed list of recommended CP improvements is presented in Appendix E. The recommended improvements do not include any work that may be necessary to repair damage caused by Hurricane Irma and any other hurricanes that may occur after August 2017. 7.1 Bridge Crossings For most bridge crossing pipelines, CP can be restored by installing new galvanic anodes as indicated in Table E-1 in Appendix E. The pipelines will require anywhere from 1 to 25 anodes as determined by the current requirement of the pipeline. The anodes can be installed in groups of up to 10 anodes joined through a header wire connected to the pipeline at one location. A total of approximately 350 anodes will be required for all bridge crossings that have inadequate CP. Test stations are recommended for many bridge crossing pipelines that do not have them. Test stations are particularly important at buried transitions to ductile iron pipe. These test stations are used for assessment of the level of CP and the quality of electrical isolation from ductile iron pipe at that location. Test stations are not necessarily required for short pipelines if they have a test station at the transition. In the absence of any test stations, however, it will be necessary to contact the exposed pipe with a sharp metal point whenever a CP test is made. A total of 92 new test stations are recommended for the bridge crossing pipelines. There are 2 bridge crossing pipelines with high current requirements that make galvanic anodes impractical, and an impressed current (rectifier) station will be required at each location. These locations are the west side of Tea Table Relief and the east side of Whale Harbor Channel. However, the length of steel pipeline at each location requires confirmation by the FKAA before a final determination can be made. There are also 11 other locations where the length of steel pipeline requires confirmation, because field tests indicated the possibility that long lengths of steel pipeline could be present. These locations are described in Appendix A. Restoration of electrical isolation will be required at approximately 4 locations. Each location will involve repair of a flange insulating kit or installation of an insulating flexible coupling. Testing and repair of electrical continuity will be required at an estimated 6 locations, and these are associated with the steel pipelines with suspected longer lengths described above. 7.2 Other Facilities Recommended CP improvements for other steel transmission mains on Key West, Marathon, and at MM 121-122 in the 18-Mile Stretch were described with the test results in the respective sections of this report. Less construction work will be required for CP improvements at these locations, compared to the combined work required at bridge crossings. Recommended CP improvements for other facilities are presented in Table E-2 in Appendix E. 7.3 Operation and Maintenance Improvements This section presents suggestions for improved efficiency and effectiveness of CP systems for consideration by the FKAA. These suggestions are based on observations made over the course of the CP assessment in 2017 and our understanding of FKAA operations. Request for Proposal EXHIBIT A SECTION 7 – RECOMMENDED IMPROVEMENTS 7.3.1 Organizational Approach to Maintenance of CP Facilities The FKAA’s CP systems are relatively complex because of the mixture and configuration of steel and ductile iron pipe materials in the water transmission system. This complexity adds time and effort required to maintain the systems. At present, monitoring and maintenance of the FKAA’s CP systems are the responsibilities of the FKAA’s electricians. However, the electricians have other responsibilities, and their time is often spent on other more urgent needs that take priority over CP tasks. While CP is important, its priority will tend to slip with this arrangement and especially if electrician staffing shortages occur. The FKAA electricians also have expertise in other areas that are critical to FKAA operations but are not necessarily required for CP. From this perspective, CP maintenance is an inefficient use of the limited and valuable resources of the FKAA electricians. At the same time, the electricians have relatively limited CP training and rely on contract services for advice in situations where they need assistance to manage the complex CP systems for the water transmission mains. The FKAA electricians could benefit from additional CP training if they continue to maintain the CP systems. A better arrangement might be for the FKAA to assign in-house resources specifically to CP maintenance, with 2 levels of expertise: a basic level for routine work; and a higher level for planning and troubleshooting that will inevitably be needed. One challenge of having an in-house center of expertise is the linear arrangement of the transmission system and the inefficiencies of travel to CP facilities over 125 miles of service area. Experience suggests that CP work is favored by certain interests and aptitudes that may not necessarily match capabilities of available resources. Alternatively, the FKAA could consider contracting for CP services using a staff augmentation approach over a prolonged period. This approach has its advantages and disadvantages, but it has been used by other utilities in an effort to improve leverage of internal resources. 7.3.2 Remote Monitoring of Rectifiers At present, the FKAA manually monitors impressed current CP stations by electricians periodically visiting the sites and observing the rectifier panel meters to determine if the equipment is on and operating properly. Maintaining a regular monitoring schedule is challenging due to the limited electrician resources described above. Moreover, this approach does not promptly disclose problems that automatically turn off rectifiers, such as tripped breakers that may occur during electrical power surges or thunderstorms. The FKAA could consider ‘remote monitoring’ to improve the efficiency and effectiveness of maintaining the rectifier stations. Remote monitoring refers to periodic automated collection of CP rectifier operating data. This is similar to automated reading of water meters and wastewater pumping stations that is already in use by the FKAA. There is an industry trend toward remote monitoring of CP rectifiers to reduce labor costs and provide more timely information than manual methods. Reliability of equipment has been a challenge during development of remote monitoring technology, but reliability has improved, and the benefits of remote monitoring far outweigh the costs. There are several manufacturers of remote monitoring equipment for CP applications. Two of them are Borin and Abriox. All manufacturers offer a free trial use of their equipment in hopes of securing a contract for equipment and monitoring service. The remote monitoring units can be purchased and added to existing rectifiers at a cost of around $3,000 per station. The remote unit collects the information per program instructions and transmits it by digital cellular telephone or satellite. There is also a system that utilizes 900 megahertz radio frequency.

The data are downloaded by the remote monitoring manufacturer or service provider and placed on a private website accessed by the customer. In addition to regular monitoring, automated alert messages are sent by e-mail or telephone if the reported parameters are outside the limits set for the station. A monthly subscription costs around $10 per unit. The FKAA could try the remote monitoring approach offered by one or more companies on a trial basis. The rectifiers in Key West or Marathon would be good candidates for a trial evaluation.

SECTION 8 Construction Cost Opinion

This section presents a construction cost opinion for the recommended CP improvements, assuming that the work would be completed under a publicly bid construction contract. The construction cost opinion should be considered preliminary, because it is based on elements of work that are anticipated for construction but have not yet been designed. The cost opinion aligns with a Class 4 Estimate as described by AACE International Recommended Practice 18R-97. Engineer’s cost opinions are based on experience and judgement. Since CH2M has no control over market conditions or bidding procedures, CH2M cannot warrant that bids or ultimate construction costs will not vary from these opinions. Appropriate contingencies should be provided by FKAA. A summary of estimated construction costs is presented in Table 8-1. The total estimated construction cost of the project is $1.4 million, assuming a 20 percent cost premium for the Keys, 5 percent inflation allowance for 2018, and 20 percent project contingency. The cost estimate does not include the cost of additional work that may be needed to mitigate hurricane damage occurring after August 2017, nor does it provide for possible increased construction costs that may result from hurricane damage to property and infrastructure in the Keys. Table 8-1 Class 4 Construction Cost Estimate FKAA CP Improvements FKAA Facility or Location Estimated Construction Cost 2018 Bridge Crossings $1,014,000 Key West 79,000 Marathon 16,000 MM 121-122 47,000 Road Crossings 193,000 Total $1,358,000

The FKAA should also allow for administrative costs associated with construction, including contract management, submittal review, inspection, and documentation such as record drawings. 8.1 Basis for Estimated Costs The cost of construction will be determined by the quantities and types of CP facilities such as test stations and anodes at each pipeline. An itemized list of CP improvements with the estimated cost of construction is presented in Appendix F, Table F-1, and followed by unit cost developments. Elements of work will be essentially the same as those used for Phase 1 and Phase 2 CP Improvements. Estimated costs of the work elements have been updated to reflect current costs. For perspective, the low bid for Phase 1 construction in 2001 was 12 percent less than the Engineer’s cost opinion, and the low bid for Phase 2 construction in 2005 was 18 percent less. Changes during construction of both projects pushed actual costs closer to the Engineer’s cost opinions. The construction costs for CP work at bridge crossings will be affected by the actual lengths of the steel pipelines. The cost estimate is based on pipeline lengths established during Phase 1 or Phase 2 CP Improvements, or on estimated lengths that were strongly indicated by test results in 2017. Costs are not included for lengths of pipeline that may be constructed from steel pipe but could not be tested due

Request for Proposal EXHIBIT A SECTION 8 – CONSTRUCTION COST OPINION

to the absence of test stations. However, costs are included for CP of road crossings, because it is likely that they are all constructed from steel pipe and that CP facilities at all crossings will be like those at other crossings where CP has been installed during Phase 1 or Phase 2 CP Improvements. Design details that have not yet been determined, but will ultimately affect costs, include the exact locations of construction and working conditions at those sites. For example, installation of anodes near bridge abutments will require excavation on sloping ground behind guardrails, and the associated challenges will increase costs compared to work on flat sites with easy access. Bid documents will also include other unit price items that cannot be quantified until construction is underway. Unit price items for this project will likely include exploratory excavations, repair of insulating fittings, installation of continuity bonds on pipe joints, and asphalt pavement repair. 8.2 Cost Savings Some savings in construction cost have already been achieved by actions of the FKAA during the field investigation of the CP systems. The most significant savings resulted from the use of the existing impressed current station at Knight’s Key in Marathon to protect the buried 24-in steel transmission main at Seven Mile Bridge. The FKAA deactivated a section of the 18-in steel transmission main that the station previously protected. The use of the existing station avoided the need to construct new CP facilities for the pipeline and produced estimated construction cost savings of at least $28,000. Cost savings also resulted from the FKAA’s recovery of the bond station on the 30-in steel transmission main at Aviation Boulevard in Marathon. The cost of constructing a new station was avoided, with an estimated savings of approximately $4,000. The FKAA also recovered several other previously buried test stations worth approximately $3,000 per station in replacement cost. The total cost savings achieved by the FKAA through these actions was approximately $40,000. For additional cost savings, the FKAA could consider using its own forces to construct some or all of the recommended CP improvements. Many of the CP improvements are relatively simple, and the FKAA has adequate in-house knowledge and experience necessary to construct them. A CP specialist could be contracted for supplemental technical assistance as needed. The practicality of this approach depends on the priorities and availability of resources within the FKAA. 8.3 Recommendations The current planned CIP funding does not provide adequate budget for the recommended CP system improvements described above. Unlike a typical prioritization of projects, all of the recommended CP systems improvements have more or less the same level of importance – to provide protection of the steel transmission main sections against corrosion and extend their service life. In essence, the CP system serves as insurance to reduce the premature need for costly main emergency repair or replacement. CP is relatively inexpensive in comparison, easy to maintain and proven in its effectiveness. It is strongly recommended that the FKAA formulate a combination of CIP funding and a commitment of internal resources to complete the improvements needed to bring the CP into conformance with the design intent.

Narrative Description of Bridge Crossings

This section describes the history of CP at each bridge crossing of the FKAA’s steel transmission main and the results of an assessment made of the CP status in 2017. The crossings are listed in order of increasing Mile Marker (MM).

Cow Key Channel

West Side ‐ MM 4.2 This section covers the buried 18‐in steel transmission main on Key West at the bridge over Cow Key Channel. The pipeline is in the median of US 1 at this location. There were no CP records found for the buried steel transmission main at this location. In 2017, visual inspection of the site indicated that the pipeline enters the ground near the bridge. No test stations were found. Using direct contact to the exposed steel pipe on the bridge, the pipe‐to‐soil potential (PSP) was ‐540 millivolts (mV) to a copper sulfate reference electrode (CSE), which indicates that the buried steel pipe does not have CP. The cathodic current requirement of the buried steel pipeline was 40 milliamperes (mA), which suggests that it has a short length and is electrically isolated. Electronic location of the buried pipeline indicated that a transition or some other form of electrical isolation occurs within 20 feet of the bridge. East Side – MM 4.3 This section covers the 18‐in buried steel transmission main on Stock Island at the bridge over Cow Key Channel. The pipeline is in the median of US 1 at this location. The CP records show that the PSP of this pipeline was last tested in 1998 at a test station on the east side of the channel. The PSP was ‐780 mV CSE, indicating marginal CP for buried steel. In 2017, visual inspection of the site indicated that the pipeline enters the ground near the bridge. No test stations were found. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐510 mV CSE, indicating that the buried steel pipeline does not have adequate CP. The cathodic current requirement of the pipeline was 161 mA, which suggests that it has limited length and is electrically isolated. The results of electronic location of the buried steel pipeline were not definitive but suggested that it is electrically isolated near the valve vault located 160 feet from the bridge. Boca Chica Channel West Side ‐ MM 6.0 This section covers the 24‐in buried steel transmission main on Stock Island at the bridge over Boca Chica Channel. The pipeline is on the Florida Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the pipeline adjacent to the bridge has a buried length of approximately 230 feet and extends to Valve Vault (VV) S288. A buried Dresser coupling is shown 5 feet from the bridge. A transition coupling is shown 18 inches west VV S288 where the steel pipeline connected to ductile iron pipe. During Phase 1, a test station was installed eat th Dresser coupling near the bridge, and 2 zinc anodes were installed on the 5‐foot section of steel pipe. Two zinc anodes may have been installed on the longer section of steel pipe (the drawings are unclear on this point). A test station was installed at the transition coupling,e and on zinc anode was installed on the 18‐inch long section of steel pipeline near the vault.

In 2017, testing at the test station near the bridge indicated that the PSP of the buried steel pipeline was ‐530 mV CSE on the channel side of the Dresser coupling and ‐363 mV CSE on the other side. These results indicate that both sections of steel pipeline do not have adequate CP but are electrically isolated from each other. Using the test station, the cathodic current requirement of the short pipeline was determined to be approximately 30 mA, which suggests that the steel pipe has a short length and is electrically isolated. A test station was not found at VV S288; it was presumed buried or destroyed, and no tests were conducted. The 225 feet of steel pipeline can be expected to have cathodic current requirement proportionate to its length. East Side ‐ MM 6.5 This section covers the 24‐in buried steel transmission main on Big Coppitt Key at the bridge over Boca Chica Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the buried steel pipeline extends 291 feet from thee bridg to VV S282. A Dresser coupling is shown 7 feet from the bridge, and a buried transition coupling is shown 6 inches from the vault. A cased crossing of US 1 with 24‐in steel pipe is shown upstream from the vault. During Phase 1, a test station was installed at the Dresser coupling near the bridge, and 1 zinc anode was installed on the 7‐foot section of steel pipe. Two zinc anodes may have been installed on the longer section of steel pipe (the drawings are unclear on this point). Test stations were installed at 2 transition couplingsr nea the vault. In 2017, no test stations were found and were presumed missing or destroyed. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐674 mV CSE, which indicates that the buried section of steel pipeline has marginal CP. The cathodic current requirement of the pipeline was 20 mA, which suggests that the steel pipe at the channel does indeed have short length and is electrically isolated from the longer section of steel pipeline. No tests were conducted on the longer section of steel pipeline or on the cased crossing due to the absence of test stations. The 284 feet ofd burie steel pipeline can be expected to have cathodic current requirement proportionate to its length. The steel carrier pipeline will have a cathodic current requirement proportionate to the length of pipe that is buried or submerged, including the portion inside the casing. Rockland Channel West Side ‐ MM 9.8 This section covers the 24‐in buried steel transmission main on Big Coppitt Key at the bridge over Rockland Channel. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 328 feet, and that the transition to ductile iron pipe occurs at a buried insulated flange 12 inches outside VV S274. A test station and 4 zinc anodes were installed on this section of steel pipeline. Another test station was installed 37 feet from the bridge. In 2017, tests made at the test stations showed that the PSP of the steel pipe was ‐960 to ‐995 mV CSE and that of the ductile iron pipe was ‐808 mV CSE. These results indicate that the buried section of steel pipe has adequate CP, although electrical isolation from the ductile pipe is incomplete. East Side ‐ MM 10.0 This section covers the 24‐in buried steel transmission main on Rockland Key at the bridge over Rockland Channel. The pipeline is on the Atlantic Ocean side of US 1 at this location.

There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, no test stations were found by visual inspection. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐383 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. The cathodic current requirement of the pipeline was 47 mA, which suggests that it has limited length and is electrically isolated. Electronic location of the pipeline indicated that the transition or other form of electrical isolation occurs at VV S268, which is located 479 feet from the bridge. Shark Channel

West Side ‐ MM 11.3 This section covers the 24‐in buried steel transmission main in the Shark Key area of Big Coppitt Key at the bridge over Shark Channel. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 391 feet, with a Dresser coupling 53 feet east of VV S266, where the transition to ductile iron pipe is presumed to occur. A test station was installed at the coupling, and 2 magnesium anodes were installed on the steel section of pipeline. In 2017, the test station was not found by visual inspection and was presumed buried or destroyed by construction of the Heritage Trail at that location. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐1,099 mV CSE, which indicates that the buried section of steel pipeline has adequate CP and is electrically isolated. East Side ‐ MM 11.8 This section covers the 24‐in buried steel transmission main on Saddlebunch No. 5 Key at the bridge over Shark Channel. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 699 feet and transitions to ductile iron pipe at VV S260. Test stations were installed near the bridge abutment and at the vault, and a total of 10 magnesium anodes were installed on this section of steel pipeline. In 2017, only the test station at the bridge was found during visual inspection of the site. Using the test station, the PSP was ‐511 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. The cathodic current requirement was very high at 2,800 mA. Electronic location of the pipeline showed that it is shorted to (electrically continuous with) the 18‐in steel transmission main at the valve vault. This result indicates that failure of the electrical isolation of the 18‐in pipeline has occurred at the vault. The 18‐inch main does not have CP, and the anodes on the 24‐in pipeline cannot provide protection for both pipelines. The anodes installed on the 24‐in pipeline may have been consumed by the high current requirement of the 18‐in pipeline. The distance from the bridge abutment to VV S260 was measured at 642 feet and not 699 feet as shown on the record drawing. Saddlebunch No. 5 Channel West Side ‐ MM 12.6 This section covers the 24‐in buried steel transmission main on Saddlebunch No. 5 Key at the bridge over Saddlebunch No. 5 Channel. The pipeline is on the Ocean side of US 1 at this location. There has been no CP work on the 24‐in buried steel transmission main at this location since it was last tested and found protected in 1998. 3

East Side ‐ MM 12.8 This section covers the 24‐in buried steel transmission main on Saddlebunch No. 4 Key at the bridge over Saddlebunch No. 5 Channel. The pipeline is on the Ocean side of US 1 at this location.

A test station was installed at the transition, and 5 magnesium anodes were installed on this section of pipeline. In 2017, the test station was not found and was presumed buried or destroyed. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐1,503 mV CSE, which indicates that the steel pipeline has adequate CP and is electrically isolated. The pipeline was electronically located from the bridge to the anodes installed during Phase 1. Saddlebunch No. 4 Channel West Side ‐ MM 13.1 This section covers the 24‐in buried steel transmission main on Saddlebunch No. 4 Key at the bridge over Saddlebunch No. 4 Channel. The pipeline is on the Ocean side of US 1 at this location.

A test station was installed at the transition, and 4 magnesium anodes were installed on this section of pipeline. In 2017, the test station was not found; the FKAA’s records indicate that it was buried or destroyed in 2016. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐1,417 mV CSE, which indicates that the buried steel pipeline has adequate CP and is electrically isolated. The pipeline was electronically located from the bridge to the anodes that were installed during Phase 1.

Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐979 mV CSE, which indicates that the buried steel pipeline has adequate CP and is electrically isolated. The pipeline was electronically located from the bridge to anodes installed during Phase 1. An old test station was found at this location and appears to be on the 18‐inch steel main, which is not in service at this location. The PSP at the test station was ‐988 mV CSE, indicating adequate CP of the buried steel pipeline. East Side ‐ MM 14.4 This section covers the 24‐in buried steel transmission main on Saddlebunch No. 2 Key at the bridge over Saddlebunch No. 3 Channel.

Saddlebunch No. 2 Channel West Side ‐ MM 14.5 This section covers the 24‐in buried steel transmission main on Saddlebunch No. 2 Key at the bridge over Saddlebunch No. 2 Channel. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 243 feet before it transitions to ductile iron pipe. A test station was installed at the transition, and 5 magnesium anodes were installed on this section of steel pipe. The test station at the transition was found and tested. The PSP of the steel pipeline was ‐1,402 mV CSE and that of the ductile iron was ‐358 mV CSE. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐1,532 mV CSE. These results indicate that the buried steel pipeline has adequate CP and is electrically isolated. East Side ‐ MM 14.8 This section covers the 24‐in buried steel transmission main on Bay Point at the bridge over Saddlebunch No. 2 Channel. The pipeline is on the Ocean side of US 1 at this location.

Lower Sugarloaf Channel West Side ‐ MM 15.2 This section covers the 24‐in buried steel transmission main on Bay Point, on the west side of the bridge over Lower Sugarloaf Channel. The pipeline is on the Ocean side of US 1 at this location. There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, no test stations were found by visual inspection. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐292 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. The cathodic current requirement of the pipe was 60 mA, which suggests that the buried steel pipeline has limited length and is electrically isolated. The results of electronic location of the pipeline were unclear but suggested that the transition or another form of electrical isolation occurs about 143 feet from the bridge abutment and about 125 feet east of VV S238. It is possible that the transition occurs at the vault. East Side ‐ MM 15.5 This section covers the 24‐in buried steel transmission main on an unnamed key on the east side of the bridge over Lower Sugarloaf Channel. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 279 feet. It connects to a buried insulated flange and continues as buried steel pipe for 1 foot before passing through VV S238. On the other side of the vault, the buried steel pipe continues for another 1 foot and then has an insulated flange connection to ductile iron pipe. Test stations were installed at both insulated flanges, and 5 magnesium anodes were installed on the longer section of steel pipe. There is no indication that anodes were installed on the short lengths of buried steel pipe adjacent to the vault. In 2017, tests made at the test station on the channel (west) side of the vault indicated that the PSP of the pipe from the bridge was ‐435 mV CSE and that of the pipe at the vault was ‐455 mV CSE. At the test station on the island (east) side of the vault, the PSP of the steel pipe at the vault was ‐310 mV CSE and that of the ductile iron pipe was ‐370 mV CSE. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐458 mV CSE. These results indicate that the buried steel pipeline does not have adequate CP, although the buried insulated flanges appear to be functional. The cathodic current requirement of the 279 feet of buried steel pipe was 155 mA. This result supports the results of other tests indicating that the pipe is electrically isolated. The cathodic current requirement of the buried pipe adjacent to the vault is minimal but would require an additional anode on each side of the vault for CP. Harris Channel West Side ‐ MM 16.4 This section covers the 24‐in buried steel transmission main on an unnamed key on the west side of the bridge over Harris Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that 2 magnesium anodes were installed on the buried steel pipe near the bridge. No work was done to the existing test station. In 2017, the test station was found near the bridge abutment and was an oxidized ‘Flush Fink’ thermoplastic box. Tests showed that the test leads were not functional. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐292 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. 6 Request for Proposal EXHIBIT A

The cathodic current requirement of the pipe was 110 mA, which suggests that the buried steel pipeline is electrically isolated. Electronic location of the pipeline indicated that the transition or some other form of electrical isolation occurs 571 feet from the bridge abutment. East Side ‐ MM 16.5 This section covers the 24‐in buried steel transmission main on Lower Sugarloaf Key at the bridge over Harris Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 13 feet before its connection to ductile iron pipe at a buried Dresser coupling. A test station was installed at the coupling, and 2 magnesium anodes were installed on this section of pipe. In 2017, the test station was found and tested. The PSP of the steel bridge pipe was ‐587 mV CSE and that of the pipe on the other side of the coupling was ‐545 mV CSE. The cathodic current requirement was 140 mA, which seems high for such a short length of pipe. The high, although manageable, current requirement at this location might be explained by poor quality coating on the pipeline. Tests showed that the Dresser coupling provided electrical isolation of the connecting pipes from each other, and that the pipeline was not electrically continuous across the bridge or ‘shorted’ to it. Electronic location of the pipeline indicated that the coupling was located at the test station and confirmed that it was a functional as an insulator. Harris Gap Channel West Side ‐ MM 17.5 This section covers the 24‐in buried steel transmission main on Lower Sugarloaf Key at the bridge over Harris Gap Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 24 feet before it transitions to ductile iron pipe. A test station was installed at the transition, and 2 magnesium anodes were installed on this section of steel pipeline. In 2017, the test station at the transition was found partially covered by asphalt pavement. It was chipped dout an tested. The PSP of the steel pipeline was ‐723 mV CSE and that of the ductile iron was ‐ 447 mV CSE. The tests results indicate that CP is marginal for the buried steel pipeline, although it is electrically isolated from the ductile iron pipe. The cathodic current requirement for full protection of the buried steel pipeline was 70 mA, which is high but manageable for the short length of pipe at this location. East Side ‐ MM 17.5 This section covers the 24‐in buried steel transmission main on an unnamed key on the east side of the bridge over Harris Gap Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 25 feet before it transitions to ductile iron pipe. A test station was installed at the transition, and 3 zinc anodes were installed on this section of steel pipeline. In 2017, the test station at the transition was found by visual inspection. The PSP of the steel pipe was ‐ 475 mV CSE and that of the ductile iron was ‐361 mV CSE. These test results indicate that the steel pipe does not have adequate CP, although it is electrically isolated from the ductile iron pipe. The cathodic current requirement of the buried steel pipe was 112 mA, which is high, but manageable, for the short length of pipeline.

North Harris Channel West Side ‐ MM 17.8 This section covers the 24‐in buried steel transmission main on an unnamed key on the west side of the bridge over North Harris Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 25 feet before it transitions to ductile iron pipe. A test station was installed at the transition, and 2 magnesium anodes were installed on this section of steel pipe. In 2017, the test station at the transition was found. The PSP of the steel pipeline was ‐477 mV CSE and that of the ductile iron was ‐463 mV CSE. These test results indicate that the steel pipeline does not have adequate CP. The cathodic current requirement of the buried steel pipeline was 138 mA, which is high, but manageable, for the short length of pipeline and confirms that it is electrically isolated. Electronic location of the buried steel pipeline indicated that the transition or another form of electrical isolation occurst at the tes station. An old ‘Flush Fink’ thermoplastic test station was found near the abutment. Inspection of the exposed pipe showed that old test wires were attached to it. However, the wires were cut off a short distance from the pipe and were not functional. East Side ‐ MM 17.8 This section covers the 24‐in buried steel transmission main on Park Key at the bridge over North Harris Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 25 feet before it transitions to ductile iron pipe. A test station was installed at the transition and 3 zinc anodes were installed on this section of steel pipe. In 2017, the test station at the transition was found partially covered by asphalt pavement. It was chipped out and tested. The PSP of the steel pipe was ‐627 mV CSE and that of the ductile iron was ‐502 mV CSE. The tests results indicate that CP is marginal for the buried steel pipe, although it is electrically isolated from the ductile iron pipe. The cathodic current requirement of the buried steel pipe was 51 mA, which is moderately high but manageable for the short length of pipe at this location. An old ‘Flush Fink’ thermoplastic test station was found 10 feet near the bridge abutment. The test wires were traced to the pipeline but were cut off a short distance from it and were not functional. Park Channel West Side – MM 18.7 This section covers the 24‐in buried steel transmission main on Park Key at the bridge over Park Channel. The pipeline is on the Bay side of US 1 at this location. There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, an old, broken ‘Flush Fink’ thermoplastic test station was found 16 feet from the bridge abutment. The test box contained 2 wires from the pipe and 1 wire from an old magnesium anode. The test wires were cut or broken and were not functional. Tests showed that the anode produced only 1 mA of current so it was substantially consumed. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐490 mV CSE, which indicates that the buried section of steel pipeline does not have adequate CP. The cathodic current requirement of the pipe was 45 mA, which suggests that the buried steel pipeline is electrically isolated. Electronic

Request for Proposal EXHIBIT A location of the pipe indicated that the transition or another form of electrical isolation occurs 448 feet from the bridge abutment. The current requirement seems low for the length of steel pipeline indicated by the electronic locator, so the buried pipe material should be confirmed. There may also be other buried steel transmission main on Park Key. The FKAA’s valve vault drawings showed steel pipe on both sides of VV S222. East Side – MM 18.8 This section covers the 24‐in buried steel transmission main on Upper Sugarloaf Key at the bridge over Park Channel. The pipeline is on the Bay side of US 1 at this location.

In 2017, an old test station was found 16 feet near the bridge abutment; it was an old oxidized ‘Flush Fink’ thermoplastic box that broke apart when it was opened. The test station contained 2 test wires to the pipe and 1 wire to a magnesium anode. All wires were functional. One of the pipe wires was connected to the anode wire, and the P/S was ‐967 mV CSE, indicating that CP was adequate. The wires were left connected as they were found. Electronic location of the pipe indicated that the transition or some other form of electrical isolation occurs 18 feet from the bridge abutment and in the immediate vicinity of the test station.

The PSP of the steel pipe was ‐746 mV CSE and that of the ductile iron was ‐557 mV CSE. These test results indicate that the CP is marginal for the buried steel pipe, but that the pipeline is electrically isolated. The cathodic current requirement of the buried steel pipeline was 80 mA, which seems relatively high but confirms electrical isolation. East Side – MM 20.5 This section covers the 24‐in buried steel transmission main on Cudjoe Key at the bridge over Bow Channel. The pipeline is on the Ocean side of US 1 at this location. There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, no test stations were found. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐458 mV CSE, which indicates that the buried section of steel pipe does not have adequate CP.

Test results indicate that the steel pipeline is electrically isolated from the ductile iron pipe. Niles Channel West Side – MM 25.4 This section covers the 24‐in buried steel transmission main on Summerland Key at the bridge over Niles Channel. The Niles Channel bridge is a box girder design with a hollow space where the transmission main is located. After the steel transmission main exits the bridge, the pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 138 feet before it transitions to ductile iron pipe. A test station was installed at the transition, and 3 magnesium anodes were installed on this section of pipeline. Another test station was installed at the bridge with leads to the pipeline inside the concrete bridge. In 2017, the test stations were found. Tests made at the test stations indicated that the PSP of the steel pipeline was ‐638 to ‐705 mV CSE and that of the ductile iron pipe was ‐257 mV CSE. These results indicate that the buried steel pipeline has marginal CP, although it appears to be electrically isolated from the bridge and from the ductile iron pipe. The cathodic current requirement of the buried steel pipeline was 198 mA. East Side – MM 26.3 This section covers the 24‐in buried steel transmission main on Ramrod Key at the bridge over Niles Channel. The Niles Channel bridge is a box girder design with a hollow space where the transmission main is located. After the steel transmission main exits the bridge, the pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 130 feet before it transitions to ductile iron pipe. A test station was installed at the transition, and 10 magnesium anodes were installed on this section of pipeline. Another test station was installed at the bridge with leads to the pipeline inside the concrete bridge. In 2017, the test station at the bridge was found. The site of test station at the transition was covered with trees and brush, and the test station was not found. Tests made at bridge test station indicated

10 Request for Proposal EXHIBIT A that the PSP of the steel pipe was ‐1,100 mV CSE. These results indicate that the buried steel pipeline has adequate CP, and that it is electrically isolated from the bridge and from the ductile iron pipe. Torch Ramrod Channel West Side – MM 27.6 This section covers the 24‐in buried steel transmission main on Ramrod Key at the bridge over Torch Ramrod Channel. The pipeline is on the Bay side of US 1 at this location. There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, an old ‘Flush Fink’ thermoplastic test station was found 16 feet from the bridge abutment. The test box contained 2 wires from the pipe and 1 wire from an old magnesium anode. The test wires to the pipe were functional and the PSP was ‐361 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. Tests showed that the anode produced only 2 mA of current so it was substantially consumed. The cathodic current requirement of the steel pipeline was 47 mA, which suggests that it is electrically isolated. Electronic location of the steel pipeline indicated that the transition or some other form of electrical isolation occurs 16 feet from the bridge abutment and at the location of the test station. East Side – MM 27.7 This section covers the 24‐in buried steel transmission main on Little Torch Key at the bridge over Torch Ramrod Channel. The pipeline is on the Bay side of US 1 at this location. There has been no CP work on the 24‐in buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, an old ‘Flush Fink’ thermoplastic test station was found at the bridge abutment. The test box contained 2 wires from the pipe and 1 wire from an old magnesium anode. The test wires to the pipe were functional Pand the PS was ‐384 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. Tests showed that the anode produced only 3 mA of current so it was substantially consumed. The cathodic current requirement of the pipe was 52 mA, which suggests that the buried steel pipeline is electrically isolated. Electronic location of the pipe indicated that the transition or some other form of electrical isolation occurs 24 to 35 feet from the bridge abutment. Middle Torch Road Crossing MM 27.8 This section covers the 24‐in buried steel transmission main on that crosses Middle Torch Road on Little Torch Key. The pipeline is on the Bay side of US 1 at this location. The crossing of Middle Torch Road is constructed from steel pipe in a steel casing and is approximately 80 feet long. The carrier pipe has a transition to ductile iron pipe outside the casing. A test station was installed at the transition and a zinc anode was installed on the steel carrier pipe at each end of the casing during the Phase 2 Cathodic Protection Improvements. In 2017, the westerly test station was found and tested. The PSP of the steel pipe was ‐737 mV CSE and that of the ductile iron was ‐497 mV CSE. The easterly test station was also found and tested. The PSP of the steel pipe was ‐715 mV CSE and that of the ductile iron was ‐314 mV CSE. These results indicate that the buried section of steel pipe has marginal CP, although the pipeline appears to be electrically isolated from the ductile iron pipe. The cathodic current requirement was 32 mA.

Torch Key Channel West Side – MM 28.0 This section covers the 24‐in buried steel transmission main on Middle Torch Key at the bridge over Torch Channel. The pipeline is on the Bay side of US 1 at this location. There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, an old ‘Flush Fink’ thermoplastic test station was found 16 feet from the bridge abutment. The test box contained 2 wires from the pipe and 1 wire from an old magnesium anode. The test wires were cut off at the pipe and not functional. Using direct contact to the pipe on the bridge, the PSP was ‐349 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. Tests showed that the anode produced only 3 mA of current so it was substantially consumed. The cathodic current requirement of the buries steel pipeline was 8 mA, which suggests that it is electrically isolated. Electronic location of the steel pipeline indicated that the transition or some other form of electrical isolation occurs 14 feet from the bridge abutment. East Side – MM 28.1 This section covers the 24‐in buried steel transmission main on Little Torch Key at the bridge over Torch Channel. The pipeline is on the Bay side of US 1 at this location. There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, an old ‘Flush Fink’ thermoplastic test station was found near the bridge abutment. The test box contained 2 wires from the pipe and 1 wire from an old magnesium anode. Only one of the pipe test wires was functional. Using that ewire, th PSP was ‐380 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. Tests showed that the anode produced only 2 mA of current so it was substantially consumed. The cathodic current requirement of the steel pipeline was 55 mA, which suggests that it is electrically isolated. Electronic location of the steel pipeline indicated that the transition or some other form of electrical isolation occurs approximately 20 feet from the bridge abutment. South Pine Channel West Side – MM 28.6 This section covers the 24‐in buried steel transmission main on Little Torch Key at the bridge over South Pine Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 26 feet before it transitions to ductile iron pipe. A test station was installed at the transition, and 1 magnesium anode was installed on this section of pipe. In 2017, the test station was not found by visual inspection and was presumed missing or destroyed. Test wires were found but were cut off at the pipe. A wire from an anode was also found but was damaged. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐291 mV CSE, which indicates that the buried section of steel pipe does not have adequate CP. The cathodic current requirement of the buried steel pipeline was 69 mA, which suggests that it has a short length and is electrically isolated. East Side – MM 28.8 This section covers the 24‐in buried steel transmission main on a fill area on the east side of the bridge over South Pine Channel. The pipeline is on the Bay side of US 1 at this location. 12

Request for Proposal EXHIBIT A

The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 24 feet before it transitions to ductile iron pipe. A test station was installed at the transition and 1 magnesium anode was installed on this section of pipe. In 2017, the test station was not found and was presumed missing or destroyed. Test wires were found but were attached to the channel side of a flexible coupling on the exposed pipe, which precludes their use in testing the buried pipe. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐424 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. The cathodic current requirement of the pipeline was 35 mA, which suggests that it has a short length and is electrically isolated. North Pine Channel West Side – MM 29.3 This section covers the 24‐in buried steel transmission main on a fill area on the west side of the bridge over North Pine Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 25 feet before it transitions to ductile iron pipe. A test station was installed at the transition, and 2 magnesium anodes were installed on this section of pipeline. In 2017, the test station at the transition was found and tested. The PSP of the steel pipe was ‐703 mV CSE and that of the ductile iron was ‐284 mV CSE. These test results indicate that CP is marginal for the buried steel pipeline, but that the pipeline appears to be electrically isolated. The cathodic current requirement for full CP of the buried steel pipeline was 21 mA. There is a flexible coupling on the exposed pipe at the abutment. Tests showed that the coupling has some resistance across it, so it is neither completely dielectric nor completely conductive. This could change with movement of the pipe as might occur from bridge vibration or thermal changes. East Side – MM 29.5 This section covers the 24‐in buried steel transmission main on Big Pine Key west of the bridge over North Pine Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the buried steel pipeline adjacent to the bridge has a length of 24 feet before it transitions to ductile iron pipe at a Dresser coupling. A test station was installed at the transition, and 3 zinc anodes were installed on this section of pipe. In 2017, the test station at the transition was found and tested. The PSP of the steel pipe was ‐903 mV CSE and that of the ductile iron was ‐911 mV CSE. It is unusual when the steel PSP is less negative than the ductile iron. Further tests indicated that the wire insulation colors were reversed at this station; the blue wires are connected to the ductile iron (instead of steel) and the green wires are connected to steel (instead of ductile iron). The test results indicate that CP is adequate for the buried steel pipeline but that the transition is ‘shorted’ (conductive), and the piece of ductile iron pipe to which the test wires are connected is also protected. This situation does not require correction if adequate CP is maintained on the steel pipeline. There is also a flexible coupling on the exposed pipe at the abutment. Tests showed that the coupling had some resistance across it, so it was neither completely dielectric nor completely conductive. This could change with movement of the pipe as might occur from bridge vibration or thermal changes. Spanish Harbor Channel West Side – MM 33.0 This section covers the 24‐in buried steel transmission main on Big Pine Key at the bridge over Spanish Harbor Channel. The pipeline is on the Ocean side of US 1 at this location. 13 Request for Proposal EXHIBIT A

The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 6 feet before it transitions to ductile iron pipe at a Dresser coupling. A test station was installed at the transition, and 4 zinc anodes were installed on this section of pipe. The CP Phase 1 commissioning report by the construction contractor described the conditions found upon excavation of the pipe. It revealed that a non‐insulating Dresser coupling was used at the transition, and that the pipe was under a cap of flowable fill (i.e., low‐strength Portland cement mortar) that created a dry, unfavorable environment for the anodes. The contractor recommended installation of additional anodes on the ductile iron side of the transition to boost CP, or, alternatively, replace the Dresser coupling with an insulating type. In 2017, the test station at the transition was found and tested. The PSP of the steel pipe was ‐648 mV CSE and that of the ductile iron was ‐592 mV CSE. The test results indicate that CP is marginal for the buried steel pipeline, and that electrical isolation is weak at the transition. The cathodic current requirement for CP of the buried steel pipeline was 250 mA, which is high for the length of the pipeline but not unusual considering weak electrical isolation. East Side – MM 33.6 This section covers the 24‐in buried steel transmission main on West Summerland Key at the bridge over Spanish Harbor Channel. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the buried steel pipeline adjacent to the bridge has a length of 6 feet before it transitions to ductile iron pipe at a Dresser coupling. A test station was installed at the transition, and 4 zinc anodes were installed on this section of pipe.

In 2017, the test station at the transition was found and tested. The PSP of the steel pipeline was ‐708 mV CSE and that of the ductile iron was ‐708 mV CSE. The test results indicate that CP is marginal for the buried steel pipe, and that the transition is ‘shorted’ (conductive) such that the piece of ductile iron pipe to which the test wires are connected is also protected. The cathodic current requirement for CP of the buried steel pipeline was 130 mA, which is high for the length of thet pipeline bu not unusual considering the ‘shorted’ electrical isolation. Bahia Honda Channel West Side – MM 35.3 This section covers the 24‐in buried steel transmission main on West Summerland Key at the bridge over Bahia Honda Channel. The pipeline is in the median of US 1 at this location. The CP Phase 1 redline drawings show that the buried steel pipeline adjacent to the bridge has a Dresser coupling 6 feet west of a thrust block at the bridge. A test station was installed 10 feet from the thrust block, and 2 magnesium anodes were installed on this section of pipe. The anode leads were connected to a pipe lead in the test station. In 2017, the test station was found and tested. It was a ‘Big Fink’ post type that contained 2 wires from the pipe and 2 wires from the anodes. Tests showed that only 1 pipe lead and 1 anode lead were functional. Using the functional pipe test lead, the PSP was ‐196 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. The low value of the potential suggests that the pipe is embedded in the buried concrete thrust block as it appears by inspection.

The cathodic current requirement of the pipe was 2,000 mA which seems high. However, electronic location of the pipe indicated that it is continuous from the test station at the bridge to the test station near VV S122/SA124, located approximately 970 feet from the bridge. The test station at VV S122/SA124 was installed during Phase 2 CP Improvements. Tests showed that the green insulated wires in the test station were connected to the steel pipeline from the bridge. Based on current requirement tests and electronic location, the buried steel pipeline appears to extend 970 feet from the bridge to the east side of VV S122/SA124. East Side – MM 36.6 This section covers the 24‐in buried steel transmission main on Bahia Honda Key at the bridge over Bahia Honda Channel. The pipeline is in the median of US 1 at this location. There was no CP work done on the buried steel transmission main at this location during Phase 1 CP Improvements, because the pipe was tested and found protected in 1998. In 2017, inspection of the site revealed an old ‘Flush Fink’ thermoplastic test station near the bridge abutment in the median. The test box contained 2 wires from the pipe and 1 wire from an old magnesium anode. The wire connections were corroded in the test box so they were disconnected and cleaned. After cleaning, the P/S of the pipe lead was ‐395 mV CSE without the anode connected and ‐ 589 mV CSE with it connected; the anode current was 51 mA. The test results indicate that the buried steel pipeline does not have adequate CP even with the anode connected. Electronic location of the steel pipeline indicated that it was continuous for some distance east of the bridge. Tracing the pipe led to a flush iron test station in the median approximately 500 feet from the bridge. The test station contained two wires to the pipe and 3 wires to old anodes. Only 1 of the pipe leads was functional and was used to measure the P/S at ‐559 mV CSE. The electronic trace continued east beyond the test station, and it became apparent that the steel pipe probably continued all the way to VV S116/SA114, which is located approximately 1,850 feet from the bridge. Test stations were installed at VV S116/SA114 during Phase 2 CP Improvements. A cathodic current requirement test was conducted on the buried steel pipeline at the bridge, and results indicated continuity of the pipeline to the test station 500 feet from the bridge and to the test station on the west side VV S 116 / SA 114. Results indicated that 1000 mA of CP current would be required to protect the buried steel pipeline. Based on current requirement tests and electronic location, the buried steel pipeline appears to extend 1,800 feet from the bridge to the west side of VV S116/SA114. Ohio Bahia Honda Channel West Side – MM 38.5 This section covers the 24‐in buried steel transmission main on Bahia Honda Key at the bridge over Ohio Bahia Honda Channel. The pipeline is on the Bay side of US 1 at this location. There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, visual inspection of the site found 2 test wires attached to the pipe. The wires ran under a fenced area on the Heritage Trail, and it could not be determined if there was test station in the enclosure. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐237 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. The cathodic current requirement of the pipe was 29 mA, which suggests that the buried steel pipeline at the channel has a short length and is electrically isolated. Electronic location of the buried steel pipeline indicated that the transition occurs just outside the bridge abutment.

East Side – MM 38.7 This section covers the 24‐in buried steel transmission main on Ohio Key at the bridge over Ohio Bahia Honda Channel. The pipeline is on the Bay side of US 1 at this location. There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, no test stations were found. The exposed pipe appeared to have Cadweld wire connections under the coating, but the ends of the wires were not found. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐303 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. The cathodic current requirement of the pipeline was 100 mA, which suggests that it has moderate length and is electrically isolated. Electronic location of the pipeline indicated that the transition or some other form of electrical isolation occurs approximately 130 feet east of the bridge, near a service tap and meter. Ohio Missouri Channel West Side – MM 39.0 This section covers the 24‐in buried steel transmission main on Ohio Key at the bridge over Ohio Missouri Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 21 feet before it transitions to ductile iron pipe at a Dresser coupling. A post‐mounted test station was installed at the transition, and 1 magnesium anode was installed on this section of steel pipe. In 2017, the test station at the transition was found and tested. The PSP of the steel pipe was ‐1,286 mV CSE and that of the ductile iron was ‐190 mV CSE. These test results indicate that the buried steel pipeline has adequate CP and is electrically isolated. Electronic location of the buried steel pipeline using the blue (‘steel’) leads at the test stationd indicate that the transition occurs at the same location as the test station. However, there is reason to believe that the transmission main is constructed entirely of steel pipe on Ohio Key. Electronic location using the green (‘ductile iron’) leads at the test station traced the pipe for approximately 1,570 feet to the same area found by testing on the east side of Ohio Bahia Channel (MM 38.7) discussed above. The cathodic current requirement was 430 mA which is not unusual considering the length of the pipeline. Therefore, the ‘transition’ coupling near MM 38.7 is probably a Dresser coupling with steel pipe on each side. East Side – MM 39.3 This section covers the 24‐in buried steel transmission main on Missouri Key at the bridge over Ohio Missouri Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 25 feet before it transitions to ductile iron pipe at a Dresser coupling. A post‐mounted test station was installed at the transition, and 1 magnesium anode was installed on this section of steel pipe. In 2017, the test station at the transition was found and tested. The PSP of the steel pipe was ‐230 mV CSE and that of the ductile iron was ‐216 mV CSE. The cathodic current requirement was 125 mA. These test results indicate that the buried steel pipeline does not have adequate CP, and that isolation from the ductile iron pipe is weak. Electronic location of the pipeline suggested that the transition or other form of electrical isolation occurs at the location of the test station. However, the pipeline trace continued beyond the test station for approximately 125 feet. Considering the results of testing at the west side of Missouri Little Duck Channel (discussed below), it is possible that the transmission main on Missouri Key may be constructed entirely from steel pipe.

Missouri Little Duck Channel West Side – MM 39.6 This section covers the 24‐in buried steel transmission main on Missouri Key at the bridge over Missouri Little Duck Channel. The pipeline is on the Bay side of US 1 at this location. There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, an old ‘Flush Fink’ thermoplastic test station was found near the bridge abutment. The test box contained 2 wires from the pipe and 1 wire from an old magnesium anode. Only one of the pipe test wires was functional. Using that wire, the PSP was ‐280 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. Tests showed that the anode produced only 2 mA of current so it was substantially consumed. The cathodic current requirement of the pipeline was 55 mA, which suggests that it is electrically isolated. Electronic location of the pipe using the blue (‘steel’) leads at the test station indicated that the transition or some other form of electrical isolation occurs at the same location as the test station, approximately 20 feet from the bridge abutment. However, there is reason to believe that the transmission main is constructed entirely of steel pipe on Missouri Key. Electronic location using the green (‘ductile iron’) leads at the test station traced the pipe for approximately 1,350 feet to the same area found by testing on the east side of Ohio Missouri Channel (MM 39.3) discussed above. The cathodic current requirement was 556 mA which is not unusual considering the length of the pipeline. Therefore, the ‘transition’ coupling near MM 39.3 is probably a Dresser coupling with steel pipe on each side. East Side – MM 39.7 This section covers the 24‐in buried steel transmission main on Little Duck Key at the bridge over Missouri Little Duck Channel. The pipeline is on the Bay side of US 1 at this location. There has been no CP work on the buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, an old broken ‘Flush Fink’ thermoplastic test station was found near the bridge abutment. The test box contained 2 wires from the pipe and 1 wire from an old magnesium anode. Only 1 of the pipe test leads was functional. Using the test wire, the PSP was ‐301 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. Tests made using the anode wire indicated that the anode was substantially consumed. The cathodic current requirement of the pipeline was 30 mA, which suggests that it is electrically isolated. Electronic location of the steel pipeline indicated that the transition or some other form of electrical isolation occurs 217 feet from the bridge abutment. The transmission pipeline is probably ductile iron east of this point. The CP Phase 1 redline drawing for the west side of 7 Mile Bridge (discussed below) indicates that the contractor made 10 exploratory excavations about 300 feet east of the indicated location of the transition and found ductile iron pipe at all of them. 7 Mile Bridge West Side – MM 40.0 This section covers the 24‐in buried steel transmission main on Little Duck Key at 7 Mile Bridge. The 7 Mile bridge is a box girder design with a hollow space where the transmission main is located. After the steel transmission main exits the bridge, the pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 87 feet before it transitions to ductile iron pipe at a Dresser coupling. A post‐mounted test station 17

Request for Proposal EXHIBIT A was installed at the transition, and 1 magnesium anode was installed on this section of steel pipeline. Another post‐mounted test station was installed at the abutment with leads to the pipeline inside the concrete bridge. In 2017, the test station at the transition was found and tested. The PSP of the steel pipeline was ‐966 mV CSE and that of the ductile iron was ‐945 mV CSE. These test results indicate that the buried steel pipeline has adequate CP, but the insulating quality of the transition is weak, and the piece of ductile iron pipe to which the test wires are connected is also protected. This situation does not require correction if adequate CP is maintained on the steel pipe. East Side – MM 46.7 This section covers the 24‐in buried steel transmission main on Marathon Key at 7 Mile Bridge. The 7 Mile bridge is a box girder design with a hollow space where the transmission main is located. After the steel transmission main exits the bridge, the pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 1,153 feet before it transitions to 30‐in ductile iron pipe near VV S76/SA78. A flush‐mounted iron test station was installed at the transition, and 30 zinc anodes were installed on this section of steel pipe. Another post‐mounted test station was installed at the abutment with leads to the pipe inside the concrete bridge. During Phase 2 of the CP Improvements, an impressed current CP station was constructed near VV S76/SA78 to provide protection for the 18‐in steel main on Marathon. An additional test station was also installed at the vault. The 18‐in main is connected at the vault and crosses US 1 to Bay side, where it has a service tap to Pigeon Key. The 18‐in main was electrically isolated in the vault at its connection to the 24‐in main during Phase 2 construction. In 2017, all test stations were found and tested. Initial tests showed that the steel pipeline had a PSP of ‐476 mV CSE at the bridge and ‐438 mV CSE at the valve vault. These results indicate that it did not have adequate CP. The FKAA reported that recent landscaping work along US 1 by the City of Marathon cut the wire from the anodes to the pipeline and that the wire had not been repaired. Tests also showed that the flange insulation had failed in the 18‐in main connection in the vault, resulting in the 18‐in and 24‐in steel pipelines ‘shorted’ together. A few days after these tests were completed, the FKAA took the 18‐in main out of service and cut the pipeline on the Bay side of US 1 and a short distance from the service tap for Pigeon Key. Tests were conducted to determine if the impressed current station could be used to provide CP for the 24‐in steel pipeline to the bridge and for the 18‐in steel main crossing US 1. Test results indicated that this approach would be feasible, and that no other construction would be required. Therefore, the output of the impressed current station was adjusted to provide protection to the 18‐ and 24‐in steel pipelines. The rectifier output at the impressed current station at Knight’s Key was left at 2.52 amperes at 3.1 volts DC. The PSP on the 24‐in pipe at the bridge was ‐1,218 mV CSE and ‐924 mV CSE Instant‐Off. Similar values of PSP were measured at test stations at the vault and on the 18‐in steel main near the tap to Pigeon Key. No work other than continued monitoring is required for protection at this location. Vaca Cut West Side – MM 53.2 This section covers the 30‐in buried steel transmission main on Marathon Key at the bridge over Vaca Cut. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 861 feet before it transitions to ductile iron pipe at a buried Dresser coupling. The steel main passes through VV SA38/SA40 at 310 feet from the channel. The pipe material changes to ductile iron pipe in

18

Request for Proposal EXHIBIT A the vault but is steel on both sides of it. The 18‐in steel main was originally connected at the vault, with an insulated flange, but has since been taken out of service by the FKAA. Flush‐mounted iron test stations were installed at VV SA38/SA40 and at the transition. A total of 10 magnesium anodes and 9 zinc anodes were installed on this section of buried steel pipeline. During Phase 2 of the CP Improvements, a total of 6 additional magnesium anodes were installed here. In 2017, the test stations were found and tested. At the valve vault, the PSP of the steel pipe (with green test wires) was ‐896 mV CSE and that of the 18‐in steel main (blue test wires) was ‐900 mV CSE. At the transition, the PSP of the steel pipe was ‐1369 mV CSE and that of the ductile iron was ‐679 mV CSE, with the CSE placed on the grassy curb strip next to US 1. Using direct contact to the exposed pipe on the bridge, the PSP of the steel pipe was ‐1168 mV CSE. These test results indicate that the buried section of steel pipe has adequate CP and is electrically isolated from the ductile iron pipe at the transition. However, the insulating flange on the 18‐in steel main at the vault is not functional, and some of the CP current from the 30‐in main is going to any buried 18‐in main that still has metallic connection at the vault. East Side – MM 53.3 This section covers the 30‐in buried steel transmission main on Grassy Key at the bridge over Vaca Cut. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 996 feet before it transitions to ductile iron pipe. A test station was installed at the transition, and 10 zinc anodes were installed on this section of pipe. In 2017, the test station at the transition was not found and was presumed buried or destroyed. Using direct contact to the steel pipe on the bridge, the PSP was ‐796 mV CSE. The test results indicate that the CP is marginal for the buried steel pipeline. The cathodic current requirement for full protection of the pipeline was 110 mA, which seems reasonable for the length of pipe, and suggests that the pipe is electrically isolated at the transition. A flexible coupling is installed on the exposed pipe adjacent to the bridge abutment. Tests showed that the coupling electrically isolated the buried pipe from the exposed pipe. In addition, the pipe on the channel side of the coupling was electrically continuous with the pipe on the west side of Vaca Cut (described above). The insulating quality of the coupling could change with movement of the pipe as might occur from bridge vibration or thermal changes. US 1 Crossing on Grassy Key MM 59.5 This section covers the 30‐in buried steel transmission main on Grassy Key at Vaca Cut. The pipeline crosses US 1 at this location. The CP Phase 1 redline drawings show that the steel transmission main crossing US 1 at this location has a buried length of 604 feet, with a transition coupling to ductile iron pipe at each end. The actual crossing is the middle one‐third of this length and has a steel carrier pipe in a steel casing. The westerly portion of the steel pipeline is on the Bay side of US 1, and the easterly portion is on the Ocean side. Test stations were installed at each end of the steel pipe where it transitions to ductile iron pipe. A test station was also installed at the angle point on the Bay side of the crossing and had test wires to both the carrier pipe and the casing pipe. A total of 10 magnesium anodes were installed on this section of steel pipe, and they were installed in 2 groups of 5 anodes. In 2017, all 3 test stations were found by visual inspection and tested. The test stations at the easterly transition and at the crossing were damaged by vehicles driving over them. At the easterly transition,

19

Request for Proposal EXHIBIT A the PSP of the steel pipe was ‐642 mV CSE and that of the ductile iron was ‐498 mV CSE. At the westerly transition, the PSP of the steel pipe was ‐655 mV CSE, and that of the ductile iron was ‐571 mV CSE. At the US 1 crossing, the PSP of the steel carrier pipe was ‐693 mV CSE and that of the steel casing was ‐ 645 mV CSE, which indicates weak electrical isolation. An anode wire was found connected to a carrier pipe lead in the test station. With the anode temporarily disconnected, the PSP of the carrier pipe was ‐ 612 mV CSE. The anode current was 200 mA when connected to the pipe. The results indicate that the buried section of steel pipe has marginal CP, although it appears to be electrically isolated from the ductile iron pipe. The cathodic current requirement was 3,000 mA which seems relatively high but could be due to weak electrical isolation between the carrier pipe and the casing, or deterioration of the protective coating on the pipe, or both. Tom’s Harbor Channel West Side – MM 60.5 This section covers the 30‐in buried steel transmission main on Grassy Key at the bridge over Tom’s Harbor Channel. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 411 feet before transitioning to ductile iron pipe. A post‐mounted test station was installed at the bridge, an iron flush‐mounted test station was installed at the transition, and 4 magnesium anodes were installed on this section of steel pipe. In 2017, the test station at the bridge was found and tested. The test station at the transition was found later by the FKAA and subsequently was also tested. The PSP of the steel pipe at the bridge was ‐868 mV CSE. At the transition, the PSP of the steel pipe was ‐1121 mV CSE and that the ductile iron was ‐ 384MV CSE. These test results indicate that the buried steel pipeline has adequate CP and is electrically isolated. Electronic location of the steel pipeline indicated that the transition occurs at the same location as the test station. East Side – MM 60.8 This section covers the 30‐in buried steel transmission main on Duck Key at the bridge over Tom’s Harbor Channel. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 368 feet before transitioning to ductile iron pipe. A flush‐mounted test station was installed at the transition, and 3 zinc anodes were installed on this section of steel pipe. In 2017, the test station was not found and was presumed buried or destroyed. Using direct contact to the steel pipe at the bridge, the PSP of the steel pipeline was ‐890 mV CSE, indicating that the buried steel pipeline has adequate CP. Electronic location of the steel pipeline traced it to the approximate location of the transition, suggesting that the pipeline is electrically isolated at the transition. Tom’s Harbor Cut West Side – MM 61.4 This section covers the 30‐in buried steel transmission main on Duck Key at the bridge over Tom’s Harbor Cut. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 457 feet on Duck Key before transitioning to ductile iron pipe. A flush‐mounted test station was installed at the transition, and 5 magnesium anodes were installed on this section of steel pipe. In 2017, the test station was not found and was presumed buried or destroyed. Using direct contact to the steel pipe at the bridge, the PSP was ‐411 mV CSE, which indicates that the buried steel pipeline

20

Request for Proposal EXHIBIT A does not have adequate CP. The cathodic current requirement of the pipeline was approximately 500 mA. Electronic location of the buried steel pipeline traced it to the location of the transition, which suggests that the steel pipe is probably electrically isolated at the transition. East Side – MM 61.7 This section covers the 30‐in buried steel transmission main on Conch Key at the bridge over Tom’s Harbor Cut. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 507 feet before transitioning to ductile iron pipe at VV S4. A flush‐mounted test station was installed at the transition. A total of 10 magnesium anodes were installed on this section of steel pipe, and they were installed in 2 groups of 5 anodes. In 2017, the test station at the transition was found and tested. The PSP of the steel pipe was ‐470 mV CSE and that of the ductile iron was ‐470 mV CSE. These test results indicate that the buried steel pipeline does not have adequate CP and is not electrically isolated from the ductile iron pipe. Using direct contact to the steel pipe at the bridge, the PSP of the steel pipe at the bridge was ‐443 mV CSE. The cathodic current requirement of the pipe could not be determined, because the pipe line could not be polarized to a protected potential with the maximum available current of 2,700 mA. The test results indicate that the steel pipe is ‘shorted’ (conductive) to a large area of buried metal. It seems possible that the abandoned 18‐in steel main may have a metallic connection at or near VV S4 and will require electrical isolation before CP can be effectively applied to the buried steel pipeline at this location. Long Key Channel West Side – MM 63.1 This section covers the 30‐in buried steel transmission main on Conch Key at the bridge over Long Key Channel. The Long Key bridge is a box girder design with a hollow space where the transmission main is located. After the steel transmission main exits the bridge, the pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 1,244 feet before transitioning to ductile iron pipe near VV N4. A total of 8 magnesium anodes were installed on this section of steel pipeline, and they were installed in 2 groups of 4 anodes. A post‐ mounted test station was installed at the bridge with leads to the pipe inside the bridge. Two flush‐ mounted test stations were installed at 2 transitions near the vault, and 2 magnesium anodes were installed on approximately 20 feet of buried steel pipe west of the vault. In 2017, the test stations near VV N4 were not found and were presumed missing or destroyed. The test station at the bridge was found and tested. The PSP was ‐394 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. The cathodic current requirement of the pipeline was approximately 1,000 mA. Test results suggested that the steel pipeline is electrically isolated at the transition, but isolation cannot be confirmed without recovery or replacement of the test stations near VV N4. East Side – MM 65.5 This section covers the 30‐in buried steel transmission main on Long Key at Long Key Bridge. The Long Key Bridge is a box girder design with a hollow space where the transmission main is located. After the steel transmission main exits the bridge, the pipeline is on the Ocean side of US 1 at this location.

The steel pipeline adjacent to Long Key Bridge has a buried length of 710 feet before transitioning to ductile iron pipe. This length was determined during Phase 2 CP Improvements. There was no CP work done on the 30‐in buried steel transmission main at this location during Phase 1 CP Improvements, because the pipe was tested and found protected in 1998. During Phase 2 CP Improvements, an impressed current CP system was constructed on Long Key for protection for the 18‐in and 30‐in steel transmission mains. The rectifier station nearest to Long Key Bridge is located at MM 66.5. At MM 65.5, the 30‐in steel pipeline receives CP via its connection to the 18‐in steel main in VV N198, located about 200 feet from the bridge. Test stations were installed at VV N198, at the bridge, and at the 30‐in transition to ductile iron pipe. The test station at the bridge was found and tested. It had blue test wires and green test wires with blue tape marked W, presumably for west. This station allowed testing of the insulating quality of the flexible coupling inside the concrete bridge. The PSP using the blue wires was ‐1040 mV CSE and ‐1055 mV CSE using the green wires. These results indicate that the buried steel pipe has adequate CP, but the electrical isolation is weak at the transition. The test station at VV N198 was also found and tested. The PSP was ‐1032 mV CSE, indicating that CP is adequate for the buried steel pipe. The test station at the transition was not found and was presumed buried or destroyed. There has been recent construction work on the Heritage Trail at the location of the test station. Channel 5 West Side – MM 70.8 This section covers the 30‐in buried steel transmission main on Long Key at Channel 5 Bridge. The bridge is a box girder design with a hollow space where the transmission main is located. After the steel transmission main exits the bridge, the pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 154 feet before transitioning to ductile iron pipe. A post‐mounted test station was installed at the transition. A total of 6 magnesium anodes were installed on this section of steel pipe, in a group of 2 and a group of 4. Another test station was installed at the bridge with leads to the pipeline inside the concrete bridge. In 2017, the test station at the transition was found and tested. The PSP of the steel pipe was ‐822 mV CSE and that of the ductile iron was ‐475 mV CSE. The test station at the bridge was found, and tests indicate that the wire connections to the pipe are broken within the bridge. However, tests made at the other station were sufficient to assess CP. These test results indicate that the buried section of steel pipe has marginal CP but is electrically isolated from the ductile iron pipe. The cathodic current requirement for full protection of the buried steel pipeline was 17 mA. East Side – MM 71.1 This section covers the 30‐in buried steel transmission main on Craig Key at Channel 5 Bridge. The bridge is a box girder design with a hollow space where the transmission main is located. After the steel transmission main exits the bridge, the pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 170 feet. A post‐mounted test station was installed at the transition, and 2 magnesium anodes were installed on this section of steel pipeline. Another test station was installed at the bridge with leads to the pipeline inside the bridge.

The test station at the transition was found and tested. The PSP of the steel pipe was ‐186 mV CSE and that of the ductile iron was ‐233 mV CSE. The test station at the bridge was found, and tests indicate that the wire connections to the pipe are broken withine th bridge. However, tests made at the other station were sufficient to assess CP. These test results indicate that the buried section of steel pipe does not have adequate CP and that electrical isolation is weak at the transition to ductile iron pipe. The cathodic current requirement for CP of the buried steel pipeline was 55 mA. Channel 2 West Side – MM 72.6 This section covers the 30‐in buried steel transmission main on Craig Key at Channel 2 Bridge. The pipeline leaves the bridge on the Bay side of US 1 and crosses the highway to the Ocean side at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 231 feet before transitioning to ductile iron pipe. A post‐mounted test station was installed at the transition, which was made at a buried insulated flange. A total of 4 magnesium anodes were installed on this section of steel pipeline. Another magnesium anode was installed on the ductile iron pipe at the insulated flange. In 2017, the test station at the transition was found and tested. The test box was broken off the post and was replaced by the FKAA. The PSP of the steel pipeline was ‐527 mV CSE and thate of th ductile iron was ‐519 mV CSE. These test results indicate that the buried steel pipeline does not have adequate CP and that electrical isolation may be weak at the transition to ductile iron pipe. The cathodic current requirement for CP of the buried steel pipeline was 200 mA. The FKAA recently discovered a corrosion leak in the steel pipe where it passed through the bridge abutment and replaced a short (20 feet) section of the pipe. New test leads and 3 new magnesium anodes were installed while the excavation was open and the pipe was exposed. The new wires from the pipe and anodes had been terminated at a new flush‐mounted test station at the abutment. The new leads were tested, and the PSP was ‐497 mV CSE, consistent with the results of tests made at the transition test station. The anodes were tested and found to be non‐functional. It is possible that the anodes or their wires were damaged during backfilling, or that the anodes were backfilled with flowable fill, rock or some other unfavorable material. East Side – MM 73.0 This section covers the 30‐in buried steel transmission main on Lower Matecumbe Key at Channel 2 Bridge. The pipeline is on the Bay side of US 1 at this location. There has been no CP work on the 24‐in buried steel transmission main at this location since it was last tested and found protected in 1998. In 2017, an old ‘Flush Fink’ thermoplastic test station was found near the abutment. Inspection of the exposed pipe showed that old test wires were attached to it. However, the wires were cut off a short distance from the pipe and were not functional. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐372 mV CSE, which indicates that the buried section of steel pipe does not have adequate CP. The cathodic current requirement of the pipe was 100 mA, which suggests that the buried steel pipeline has limited length and is electrically isolated. Electronic location of the pipe indicated that the transition or some other form of electrical isolation occurs 189 feet from the bridge and at the edge of the parking area. 23

Lignumvitae Channel West Side – MM 77.6 This section covers the 30‐in steel transmission main on Lower Matecumbe Key at the bridge over Lignumvitae Channel. The pipeline is on the Bay side of US 1 at this location. CP work was completed on the pipeline during Phase 1 and Phase 2 CP Improvements. Although the projects were completed by the same construction contractor, the commissioning reports for the 2 projects differ on some points regarding the pipeline. Based on study of the reports, the probable configuration of the pipeline and history of work is summarized as follows: The steel pipeline adjacent to the bridge is buried for a length of 27 feet before transitioning to ductile iron pipe, which continues for 154 feet to a flanged joint on the east side of VV N158. Steel pipe continues from that flanged joint through the vault to another Dresser coupling 64 feet west of VV N158. The 18‐in steel main is mechanically connected in the vault and has an insulated flange at the wye to electrically isolate the 18‐in main from the 30‐in main. The 18‐in main on Lower Matecumbe Key is protected with an impressed current system. During Phase 1, a single magnesium anode was installed on the easterly 27 feet of steel pipe along with a test station at the coupling. A total of 6 magnesium anodes were installed on buried steel pipe just east of the vault, and 1 magnesium anode was installed west of the vault. During Phase 2, it was recognized that the buried flange east of VV N 158 would require installation of a flange insulating kit to achieve CP of the buried steel near the vault. However, flange insulation was not pursued due to perceived risks associated with excavation of the pipe in the steep embankment near the vault. In 2017, the post‐mounted test station 27 feet from the bridge was found and tested. The PSP of the steel was ‐823 mV CSE and that of the ductile iron was ‐708 mV, suggesting that CP is marginal for the buried steel pipe and that it is electrically isolated. The cathodic current requirement for full CP of the buried steel pipe was 30 mA. The post‐mounted test station at VV N158 was also found and tested. The leads marked “30‐in DI Wye” had a PSP of ‐753 mV CSE, and probably represent the steel main on the east side of the vault. The test leads marked “18‐in Steel” were non‐functional; the wire connections may have been made in the vault and may be broken. A test station for the 18‐in steel main on the Ocean side of US 1 was checked and had a PSP of ‐934, indicating adequate CP of the 18‐in steel main by the impressed current system. The post‐mounted test station at the transition west of VV N158 was also found and tested. The leads marked “30‐in Steel” had a PSP of ‐522 mV CSE, indicating that CP is not adequate for buried steel pipe. The leads marked “30‐in DI” had a PSP of ‐269 mV CSE and indicate electrical isolation from the steel pipe. The cathodic current requirement for CP of the buried steel pipe was approximately 300 mA, which seems high and may reflect poor quality coating on the buried steel pipe around the valve vault. East Side – MM 77.8 This section covers the 30‐in steel transmission main on Indian Key at the bridge over Lignumvitae Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 17 feet on before transitioning to ductile iron pipe. A post‐mounted test station was installed at the transition, and 3 magnesium anodes were installed on this section of steel pipe. In 2017, the test station was found and tested. The PSP of the steel pipe at the bridge was ‐49 mV CSE, and that of the ductile iron pipe was ‐36 mV CSE. These values seemed unusually low, so the integrity of the leads to steel pipe was verified by repeating the test with direct contact to the exposed pipe on the

24 Request for Proposal EXHIBIT A bridge, and the values were the same. The value of the PSP indicates that the buried section of steel pipe does not have adequate CP. The cathodic current requirement was approximately 240 mA, which seems very high for the short length of the buried steel pipeline. Electronic location of the pipe traced it to the location of the test station, which is 18 feet east of the abutment and suggests that the steel pipe is electrically isolated at that point. Tests verified that the flexible coupling on the exposed pipe was not highly conductive to the pipe on the bridge. It seems possible that the buried transmission main on Indian Key might be constructed entirely of steel pipe. The following section provides additional evidence for this possibility. Indian Key Channel West Side – MM 77.6 This section covers the 30‐in buried steel transmission main on Indian Key at the bridge over Indian Key Channel. The pipeline is on the Bay side of US 1 at this location. Records indicate that there has been no CP work on the pipeline at this location since it wasd last teste and found protected in 1998. In 2017, a newer post‐mounted test station in good condition was found behind the guardrail near the abutment. The test station had 2 blue wires, and tests confirmed that the wires were electrically connected to the exposed steel pipe on the island eside of th flexible coupling and presumably to the buried steel pipe. The PSP of the test wires was ‐120 mV CSE, which is a low value and not indicative of adequate CP for buried steel pipe. The cathodic current requirement of the buried steel pipe was 423 mA. Electronic location of the pipe using the test station wires traced it to a point 661 feet from the bridge and at the west edge of a large asphalt patch in the bike path. The indicated location has some form of electrical isolation in the pipeline, such as a flexible coupling or transition coupling. The length of Indian Key is approximately 1,400 feet between bridges, and steel pipeline was electronically traced for nearly half of that distance. Considering the low elevation and narrow width of the key, it seems possible that steel pipe might have been used for construction of all the transmission main on Indian Key. East Side – MM 78.4 This section covers the 30‐in buried steel transmission main on Indian Key Fill at the bridge over Indian Key Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 22 feet before transitioning to ductile iron pipe. An existing test station was replaced with a flush‐ mounted test station, and 3 magnesium anodes were installed on this section of steel pipe. In 2017, the test station was not found and was presumed destroyed. Test wires were found on the ground surface and were not continuous with wires that were attached to the pipe, so the wires were severed somewhere along their length. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐853 mV CSE, which indicates that CP is adequate, but barely, on the buried steel pipeline. As discussed in the following section, there is a possibility that the transmission main on Indian Key Fill may be constructed entirely from steel pipe.

Tea Table Key Channel West Side – MM 79.2 This section covers the 30‐in buried steel transmission main on Indian Key Fill at the bridge over Tea Table Key Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that 2 magnesium anodes installed on the pipeline, and an existing test station was replaced with a flush‐mounted test station. The location of the transition to ductile iron pipe was not indicated. In 2017, inspection of the site revealed broken pipe test wires and an anode wire in a saw cut in the shotcrete surfacing near the bridge abutment. The test station was apparently destroyed. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐590 mV CSE, which indicates that the buried steel pipe does not have adequate CP. The cathodic current requirement of the buried steel pipe was 100 mA. Electronic location of the pipe using the test station wires traced it to a point 48 feet from the bridge. The trace continued beyond that point but results were not as clear. It seems possible that the transmission main on Indian Key Fill may be constructed entirely of steel pipe. The length of the key is approximately 2,000 feet and a total of 709 feet of steel pipeline was indicated by electronic location. Because the island is fill at a low elevation, steel pipe with a few flexible couplings might have been used for construction of the transmission main. Confirmation of the pipe material on Indian Key Fill is needed so that CP can be provided if the pipeline is steel. East Side – MM 79.3 This section covers the 30‐in steel transmission main on Tea Table Key at the bridge over Tea Table Key Channel. The pipeline crosses US 1 at this location. The westerly portion of the steel pipeline is on the Bay side of US 1, and the easterly portion is on the Ocean side. The CP Phase 1 redline drawings show that the pipeline had 3 magnesium anodes installed, and an existing test station was replaced with a flush‐mounted test station. The location of the transition to ductile iron pipe was not indicated. In 2017, the test station was not found and appeared to have been destroyed. Severed test wires were found on the ground surface near new guardrail, and only one of leads to the pipe was functional. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐305 mV CSE, which indicates that the buried steel pipeline does not have adequate CP. The cathodic current requirement of the buried steel pipeline was 227 mA. Electronic location of the pipeline traced it to a point 600 feet from the bridge and included a crossing of US 1. The point at which the trace ended is probably a transition coupling or a flexible coupling that has insulating qualities. Tea Table Relief West Side – MM 79.7 This section covers the 30‐in steel transmission main on Tea Table Key at the bridge over Tea Table Relief. The pipeline is on the Ocean side of US 1 at this location. Records indicate that there has been no CP or other corrosion control work on the pipeline at this location since it was last considered in 1998. The steel transmission main is embedded in a concrete thrust block at the end of the bridge. In 2017, using direct contact to the exposed steel pipe outside the thrust block, the PSP was ‐364 mV CSE. This value indicates that the pipe is neither protected by CP nor fully passivated (i.e., made immune to corrosion) by embedment in the concrete. The condition is not significant unless there is buried steel

26 Request for Proposal EXHIBIT A pipe outside of the thrust block. If there is buried pipe, it would have increased risk of corrosion by galvanic action with the embedded pipe. To investigate the possibility of buried steel pipeline beyond the thrust block, the pipeline was electronically located using direct contact to the exposed steel pipe. Electronic location of the pipeline traced it to a point 260 feet from the thrust block. The point at which the trace ended is probably a transition coupling or a flexible coupling that has insulating qualities. The cathodic current requirement of the embedded and buried steel pipeline was greater than 825 mA, the maximum available test current. This value seems high for the length of the pipeline and suggests that the embedded pipe may be bare steel. Further investigation is recommended to develop a better understanding of pipeline conditions at this location and determine the best approach to CP of the buried steel transmission main. Additionally, it seems possible that the transmission main on Tea Table Key may be constructed entirely from steel pipe. Part of the key appears to be a fill area approximately 4,300 feet in length. A total of 860 feet of steel pipeline was indicated by electronic location. Because the island is fill at a low elevation, steel pipe with flexible couplings might have been used for construction of the transmission main. Confirmation of the pipe material on Tea Table Key is needed so that CP can be provided if the pipeline is steel. East Side – MM 79.8 This section covers the 30‐in steel transmission main on Upper Matecumbe Key at the bridge over Tea Table Relief. The pipeline is on the Ocean side of US 1 at this location. Records indicate that there has been no CP or other corrosion control work on the pipeline at this location since it was last considered in 1998. The east side of the Teatable Relief crossing is configured like the west side described above. However, the steel transmission main extends from the concrete thrust block to VV N140/NB142, located 430 feet west of the bridge. The 18‐in steel transmission main is also present in N140/NB142, and it receives CP from the impressed current CP system constructed for this purpose on Upper Matecumbe Key. The nearest rectifier station to Teatable Relief is located near VV N140/NB142, on the Bay side of US 1. The 30‐in steel transmission main crosses USe 1 near th rectifier station. Using direct contact to the exposed steel pipe outside the thrust block, the PSP was ‐806 mV CSE. This value indicated that the pipe was receiving some degree of CP from the impressed current system on Upper Matecumbe Key. For confirmation, the current output of ythe nearb rectifier station was temporarily increased from 1,500 to 3,500 mA. The resulting PSP of the exposed pipe was ‐828 mV CSE, reflecting increased cathodic polarization from the increased current output at the rectifier station. Further tests were not possible, because test stations that were constructed at VV N140/NB142 during the Phase 2 CP Improvements could not be found. The test stations were presumed buried or destroyed. Whale Harbor Channel West Side – MM 83.9 This section covers the 30‐in steel transmission main on Upper Matecumbe Key at the bridge over Whale Harbor Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length of 874 feet before transitioning to ductile iron pipe at VV NB134. A total of 12 magnesium anodes were installed on this section of steel pipeline, and they were installed in 2 groups of 6 anodes. An existing post‐mounted test station was replaced with a flush‐mounted station at the vault. Another existing post‐mount at the bridge was left in place.

In 2017, both test stations were found and tested, along with another test station installed during Phase 2 CP Improvements on the 18‐in steel transmission main at VV NB134. The PSP of the steel pipeline at the vault was ‐863 mV CSE and that of the ductile iron was ‐867 mV CSE. These test results indicate that the buried section of steel pipeline has adequate CP and that electrical isolation is weak at the transition to ductile iron pipe. The PSP of the 18‐in steel main was ‐895 mV CSE and that of the connected vault piping was ‐672 mV CSE. The test station at the bridge was an old ‘Big Fink’ thermoplastic post‐mount station. Tests showed that one of the 2 pipe leads was non‐functional, and the anode was consumed. Using the functional test lead, the PSP of the 30‐in steel main at the bridge was ‐859 mV CSE, indicating that CP is adequate. However, the anodes are probably near the end of their useful life. East Side – MM 84.0 This section covers the 30‐in steel transmission main on Windley Key at the bridge over Whale Harbor Channel. The pipeline is on the Bay side of US 1 at this location. The CP Phase 1 redline drawings show that the steel pipeline adjacent to the bridge has a buried length that exceeds 845 feet. A flush‐mounted test station was installed 845 feet from the bridge and adjacent to VV N130. This vault is under the westbound travel lane of US 1 and requires an FDOT permit for traffic control to access it for more than 5 minutes. The 30‐in transmission main continues east of the vault under the travel lanes of the highway for at least 3,500 feet. The location of the transition from steel to ductile iron pipe, if any, is unknown. The CP Phase 1 redline drawings also show that total of 6 magnesium anodes were installed on this section of steel pipeline, and they were installed in 2 groups of 3 anodes. One group of anodes was installed at VV N130, and the wire connections to the pipe were made in the vault. The wire connections of the test station were also made in the vault. Another existing post‐mount at the bridge was left in place. In 2017, both test stations were found and tested. The test station at the bridge was an old ‘Big Fink’ thermoplastic post‐mount station. Tests showed that both pipe leads were functional, and that the connected anode was consumed. Using the test leads, the PSP of the pipeline at the bridge was ‐583 mV CSE, indicating that CP was not adequate. The PSPs of the 2 test leads at the test station near VV N130 were ‐570 and ‐606 mV CSE. These results indicate that CP was not adequate for buried steel pipeline, and that one or both wire connections were deteriorated. A cathodic current requirement test was conducted using the test station at the bridge. A test current of 860 mA produced only a ‐15 mV change in PSP which was not adequate for CP. Additionally, no effect from the test current was seen at the test station near VV N130. The FKAA identified another old post‐mounted ‘Big Fink’ test station on the 30‐in transmission main approximately 3,100 feet east of the bridge and north of US 1. This test station had 2 pipe leads, and the PSP was ‐679 mV CSE. The leads were electronically traced to the pipeline in the westbound travel lane of US 1. It was not possible to safely trace the pipeline in US 1 due to traffic conditions. A cathodic current requirement test was conducted using the test station at 3,100 feet from the bridge. A test current of 2,550 mA produced only a ‐40 mV change in PSP which was not adequate for CP. Additionally, no effect from the test current was seen at the test station near VV N130 or at test points on the 18‐in steel transmission main further east. None of the test results provided any insights regarding the extent or condition of the 30‐in steel transmission main at this location. Additional investigation is needed to identify the location and extent of steel pipeline so that CP can be applied.

Snake Creek MM 85.6 – 85.8 The 30‐in steel transmission main has a subaqueous crossing of Snake Creek between Windley Key and Plantation Key. The pipeline is protected by an impressed current system, primarily the rectifier station at MM 85.4, that was constructed during the Phase 2 CP Improvements. The FKAA monitors the impressed current systems. The rectifier station at MM 85.4 was checked to verify that it was operating. No other tests were conducted at this location. Tavernier Creek West Side – MM 90.8 This section covers the 36‐in steel transmission main on Plantation Key on the west side of the bridge over Tavernier Creek. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that 2 magnesium anodes were installed on this section of steel pipeline, and an existing test station at the bridge was replaced with a post‐mounted station. The length of the steel pipeline and the location of the transition to ductile iron pipe were not indicated. Another existing post‐mount test station further west of the bridge was left in place. In 2017, both test stations were found and tested. Using the test station wires, the PSP of the 30‐in steel main at the bridge was ‐1014 mV CSE. These test results indicate that the buried steel pipeline has adequate CP. The post‐mounted test station was located 211 feet from the bridge. The cover and terminal board were missing, and the test wires were loose on the post. (The FKAA plans to replace the missing items and terminate the wires.) The two black test leads had a PSP of ‐760 mV CSE and that of the two white leads was ‐501 mV CSE. A single white wire to an old anode was also present. Tests showed that the black test leads were continuous with the test leads at the bridge test station and were therefore connected to the steel transmission main. The test results indicate marginal CP for the buried steel pipeline at this location. The white test leads were not identified as to their connection or purpose. Electronic location of the steel pipeline using the test station wires traced it a point 326 feet from the bridge. This is the indicated location of the transition. There were no signs of a test station at the transition. East Side – MM 91.0 This section covers the 36‐in steel transmission main on Tavernier Key at the east side of bridge over Tavernier Creek. The pipeline is on the Ocean side of US 1 at this location. The CP Phase 1 redline drawings show that the pipeline adjacent to the bridge has a buried length of 783 feet before transitioning to ductile iron pipe. A total of 16 magnesium anodes were installed on this section of steel pipeline, and they were installed in 2 groups of 8 anodes. An existing post‐mounted test station at the bridge was replaced with a similar station. Another flush‐mounted test station was installed at the transition. In 2017, both test stations were found and tested. At the bridge test station, the PSP of the steel main pipeline was ‐1191 mV CSE. At the transition test station, the PSP of the 30‐in steel main was ‐1322 mV CSE and that of the ductile iron was ‐511 mV CSE. These test results indicate that the buried steel pipeline has adequate CP and is electrically isolated from the ductile iron pipe.

Adams Waterway West Side – MM 103.4 This section covers the 36‐in steel transmission main on Key Largo at the west side of the bridge over Adams Waterway (also known as Adams Cut). The pipeline is in the median of US 1 at this location. No CP work was done at this location during Phase 1 CP Improvements. In Phase 2, the 30‐in steel transmission main from the bridge to VV NB 50 was bonded (electrically connected by wires) to the 18‐ in steel main at the vault. The bond wires consist of 2 No. 2 AWG insulated copper cables that are connected between a test station on the 18‐in main and a test station on the 30‐in main. The bond wires are direct buried outside the vault. The length of the connected, buried steel main is 737 feet. The 18‐in steel transmission main receives CP from the impressed current CP system constructed for this purpose on Key Largo. The nearest rectifier station to Adams Waterway is located at MM 104.1, on the Ocean side of US 1. Both test stations near the vault were found by visual inspection. They had test leads to the steel and ductile iron pipe at transitions buried outside the vault. The PSP of the 30‐in steel pipeline was ‐884 mV CSE, and that of the ductile iron was ‐690 mV CSE. The PSP of the 18‐in steel main was ‐912 mV CSE, and that of the ductile iron was ‐647 mV CSE. These test results indicate that both the 18‐ and 30‐in steel transmission mains have adequate CP and are electrically isolated from the ductile iron pipe at the vault. There was no evidence of a test station near the bridge. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐920 mV CSE. These test results indicate that the buried section of steel pipe has adequate CP. The 30‐in steel pipeline was electronically located from the bridge to the vault to confirm that it was electrically continuous to the vault and not beyond it. No CP work is required at this location except for continued monitoring and maintenance of CP facilities. East Side – MM 103.4 This section covers the 36‐in steel transmission main on Key Largo at the east side of the bridge over Adams Waterway (also known as Adams Cut). The pipeline is in the median of US 1 at this location. CP work was done at this location during both Phase 1 and Phase 2 CP Improvements. The CP Phase 1 redline drawings show that the pipeline adjacent to the bridge has a buried length of 308 feet before transitioning to ductile iron pipe at VV N45/NB44. The transition occurs at a buried insulated flange on the west side of the vault. A post‐mounted test station was installed at the insulated flange, and 9 magnesium anodes were installed on this section of pipeline. In Phase 2, the 30‐in steel pipeline from the bridge to VV N45/NB44 was bonded (electrically connected by wires) to the 18‐in steel transmission main at the vault. The bond wires consist of 2 No. 2 AWG insulated copper cables that are connected between a test station on the 18‐in main and a test station on the 30‐in main. The bond wires are direct buried outside the vault. The 18‐in steel transmission main receives CP from the impressed current CP system constructed for this purpose on Key Largo. The nearest rectifier station to Adams Waterway is located at MM 104.1, on the Ocean side of US 1. In 2017, both test stations near the vault were found by visual inspection. They had test leads to the steel and ductile iron pipe at transitions buried outside the vault. The PSP of the 30‐in steel pipeline was ‐996 mV CSE, and that of the ductile iron was ‐694 mV CSE. The PSP of the 18‐in steel main was ‐954 mV CSE, and that of the ductile iron was ‐647 mV CSE. These test results indicate that both the 18‐ and 30 Request for Proposal EXHIBIT A

30‐in steel transmission mains have adequate CP and are electrically isolated, although somewhat weakly, from the ductile iron pipe at the vault. The bond wire was temporarily disconnected to measure the bond current, which was 55 mA returned to the 18‐in from the 30‐in pipeline. With the bond temporarily disconnected, the 30‐in steel pipeline at the vault had a PSP of ‐916 mV CSE and that of the ductile iron was ‐773 mV CSE. The bond was reconnected after the tests were completed. At the bridge, there were test wires attached to the pipe and they went into the earth, but no test station was found. Using direct contact to the exposed steel pipe on the bridge, the PSP was ‐900 mV CSE. These test results indicate that the buried section of steel pipe has adequate CP. The 30‐in steel pipeline was electronically located from the bridge to the vault to confirm that it was electrically continuous to the vault and not beyond it. No CP work is required at this location except for continued monitoring and maintenance of CP facilities.

TECHNICAL MEMORANDUM FKAA Cathodic Protection - Restoration of Facilities Damaged or Destroyed by Hurricane Irma

PREPARED FOR: Florida Keys Aqueduct Authority PREPARED BY: CH2M DATE: January 29, 2018 PROJECT NUMBER: 694334.03.30.03

This Technical Memorandum summarizes restoration needs for cathodic protection (CP) systems operated by the Florida Keys Aqueduct Authority (FKAA). A spreadsheet with a detailed list of CP facilities damaged by Hurricane Irma and cost estimate for restoration was developed under FKAA Project 1511-17. The spreadsheet is a separate, editable Excel file that is transmitted with this report. Background The FKAA maintains an extensive array of CP systems for corrosion control of buried steel water transmission mains and submerged interior surfaces of steel water storage tanks. The CP systems are located throughout the Florida Keys and have proven essential for reliable delivery of fresh water in the corrosive marine environment of the Keys. CP is an electrochemical method of reducing corrosion of a metal surface in contact with earth or water. The FKAA’s CP facilities include galvanic anodes and impressed current systems. Impressed current systems use rectifiers to convert utility AC electrical power to DC electricity for CP. All CP facilities include ‘test stations’ that are essential for monitoring and adjusting system performance. Test stations include wires connected to buried pipe for electrical contact by workers at ground level. The FKAA operates its CP systems on a continuous basis and periodically monitors each system. Monitoring by FKAA forces is done at least annually, and engineering evaluations of the CP facilities are contracted when the need arises. The most recent monitoring of the FKAA CP facilities was done in late 2016, and an engineering evaluation by CH2M was completed in August 2017. These activities provided a thorough understanding of the condition of the FKAA’s CP facilities prior to the arrival of Hurricane Irma in September 2017. Condition Assessment In December 2017, the FKAA surveyed its CP systems to assess conditions after Hurricane Irma. Results indicated that extensive damage and destruction of many facilities had occurred due to storm surge, high winds, and debris cleanup by heavy equipment. This was not surprising because CP facilities are located outdoors and at ground level. Many test stations and rectifiers were destroyed, missing, or damaged beyond repair. CH2M is familiar with the FKAA’s CP facilities from extensive prior work including design and services during construction. CH2M reviewed the results of the FKAA’s field survey and developed a list of restoration needs by location. A total of 237 items were identified, and they were distributed over 35 islands covering 108 miles along the Florida Keys. The restoration needs were grouped in 5 categories of work: 2 types of rectifier replacement; 1 rectifier repair; and 2 types of test station replacement.

CH2M Request for Proposal EXHIBIT B FKAA CATHODIC PROTECTION - RESTORATION OF FACILITIES DAMAGED OR DESTROYED BY HURRICANE IRMA Restoration Cost Estimate CH2M prepared cost estimates for the 5 types of restoration required for CP facilities that were damaged or destroyed by Hurricane Irma. Unit costs used in the estimate were essentially the same as those used for prior CP construction contracts completed by the FKAA and known to be representative of expected costs. Unit cost estimates for the 5 types of work are attached to this report. The cost estimates for restoration of CP facilities were presented using the same spreadsheet format used for other FKAA facilities damaged by Hurricane Irma. However, all CP work was listed on a single worksheet because of the CP facilities are widely distributed throughout the Keys and the types of restoration work are similar in all affected areas. The contents of the spreadsheet columns for CP facilities are described below. Column Title Description A - B Various Not Used C Name of damage/facility Type of CP facility D Address 1 US Highway 1 Mile Marker E Address 2 Not Used F City Island/Key or Location G - L Various As Stated M Approx. Cost ($) Per spreadsheet formula N - R Various Not Used S Asset identifier Restoration Task No. (1-5) T - U Various As Stated V Man-Hours Not Used W Labor Cost per Unit ($) CH2M Estimate X Equipment cost per Unit ($) CH2M Estimate Y Material/ODC/Sub cost Per Unit ($) ODC Commissioning at 10% of Total Unit Cost Z Total Unit Cost ($) Per spreadsheet formula AA Total cost ($) Per spreadsheet formula AB - AD Various Not Used

As shown in the spreadsheet, the total estimated restoration cost for the FKAA CP facilities damaged or destroyed by Hurricane Irma is $2,139,179. This includes an allowance for necessary commissioning and testing, estimated at 10 percent of the associated cost of labor and equipment. We appreciate the opportunity to assist the FKAA in this matter. Please contact us if there are questions or if additional information is required.
