Mr. James Michel Fayetteville Public Works Commission 955 Old Wilmington Road Fayetteville, NC 28301 Reference: Report of Limited Lead-Paint Survey Two Water Towers 818 Bedrock Road and 3414 Well Street

Cumberland County, North Carolina ECS Project No. 22-23499

Dear Mr. Michel: In accordance with ECS Carolinas, LLP (ECS) proposal number 22-19811R dated July 23, 2015 and authorized on October 14, 2015, ECS is pleased to submit this report of our limited lead-based paint survey at the referenced site. This report includes a description of our understanding of the project background information, a description of the scope of work performed, including our findings, conclusions and comments.

PROJECT INFORMATION

The sites are located at 818 Bedrock Drive in Fayetteville, Cumberland County, North Carolina and 3414 Well Street in Hope Mills, Cumberland County, North Carolina. The sites are improved with water towers. The water towers are reportedly each painted one color and are equipped with access ladders with safety cables. ECS was contracted to perform a lead-based paint survey of the two water towers. The project understanding is based on correspondence between Mr. James Michel with Fayetteville PWC and Mr. Braxton Dawson with ECS.

PROCEDURE/METHODOLOGY On November 2, 2015, ECS representative Mr. Braxton Dawson, (NC Accredited Lead Inspector/Risk Assessor No. 120251) visited the site to conduct the limited lead-based paint survey. The weather conditions at the time of the site visits were approximately 60 degrees Fahrenheit and rainy. Due to safety concerns and inclement weather at the time of the assessment, ECS was unable to access surfaces greater than 16 feet above ground level. Access to the elevated tanks required additional fall protection measures which were not included in the project understanding. The surfaces were analyzed from the ground using a ladder. Limited Lead-Based Paint Survey

The purpose of the lead inspection is to identify the general location of lead-based paint surfaces. This process consists of screening various painted surfaces based on color, substrate, phase of construction, etc. for the presence of lead-based paint. The role of the lead inspector is to determine and then report the presence of lead-based paint surfaces. The lead-based paint inspection methodology follows general guidelines published by the EPA and OSHA. This process consists of screening painted surfaces (i.e. walls, ceilings, windows, window frames, doors, etc.) for lead-based paint. The lead-based paint inspection includes

obtaining readings using a calibrated RMD LPA-1 XRF Lead-Based Paint Analyzer assigned to ECS. A reading was taken at each test location as listed in Attachment A. The State of North Carolina (State) defines lead-based paint as having “a lead content of 1.0 mg/cm2 of painted surface or greater than 0.5% lead by weight.”

RESULTS The data summary tables (Attachment A) summarize the surfaces analyzed during ECS’ site visit. The lead figures (Attachment B) and photographs (Attachment C) summarize the locations of lead-based paint. Concentrations of lead in excess of or equal to EPA and State levels (1.0 mg/cm2) were detected on the following components:

The columns, crossbars, and base of the Bedrock Road water tower. The access ladder does not contain lead-based paint. ECS was unable to sample the water tank.

CONCLUSIONS AND RECOMMENDATIONS

Concentrations of lead in excess of or equal to EPA and State levels were detected on the columns, crossbars, and base of the Bedrock Road water tower. Lead-based paint was not detected on the surfaces analyzed at the Hope Mills water tower; however, ECS was unable to analyze the water tank. Please see the attached lead tables and figures for approximate locations. ECS recommends the following in regards to the building components containing lead-based paint being affected by the renovations:

1. Renovations to the materials should be done so that as little dust as possible is released.

2. Only qualified lead-based paint abatement contractors should perform lead-based paint

abatement activities.

3. The following traditional methods of paint removal are unsafe if applied to old paint containing lead because these methods are known to poison children, occupants, and workers:

Open-flame burning or torching. Machine sanding or grinding without a HEPA vacuum exhaust tool. Uncontained hydro-blasting or high pressure washing. Abrasive blasting or sand blasting. Heat guns operating above 1,100 °F

If the lead-based paint containing materials are removed, they should be removed intact and shall be disposed of at an acceptable landfill, provided landfill waste profile requirements are complied with. Disposal must comply with the land disposal restriction notification requirements of 40 CFR 258. This report summarizes our evaluation of the conditions observed at the site. The findings prepared by ECS are based upon testing performed in the buildings. Additional lead-based paint

may exist (undetected) in other areas due to their inaccessibility or due to the limited nature of our testing. Our recommendations are based on the guidelines presented in EPA, North Carolina, and OSHA lead regulations. Please note that this document is not a specification for lead removal. It does not contain means and methods for lead abatement. If you are planning a lead abatement project, please contact ECS to discuss the requirements. Use of this document without the express written consent of ECS is at the sole risk of the user and or/abatement contractor. ECS appreciates the opportunity to provide our lead paint services for this project. If you have questions or need additional information, please contact us at (910) 686-9114.

Scope of Report The scope of the investigation was to perform a visual structural inspection of the telecommunication equipment placement on the elevated water storage tank located at 818 Bedrock Drive in Fayetteville, NC as described in PWC Task Authorization Number 14F&A016. Steve Fleming, PE, John Kells, PE, SE, and Bryan Fleming, EI visited the site on March 05, 2014. Access to the site was provided by the Public Works Commission (PWC) of Fayetteville. The investigation primarily focused on the condition of the handrails at the catwalk and the telecommunication equipment support frame at the top of the tank. The information recorded on site was used to perform preliminary visual structural evaluations of the catwalk and the top steel frame to support loading from both existing and future telecommunications equipment. The investigation included a review of previous structural analysis reports and antenna mappings provided to us by PWC. The investigation did not focus on the condition of the overall tank and its ability to resist global overturning or gravity forces. However, if grossly deficient items outside our scope of work were encountered during our investigation, they were noted and will be presented in this report. Summary of Findings and Recommendations

The Bedrock Drive elevated water storage tank was found to be in fair condition, with the exception of the catwalk.

Moderate corrosion was found on primary or secondary steel members of the steel support frame located at the top of the tank. Frame members appeared to be adequate to support the existing loading; however the top plate of the tank deflected under the load of the frame posts.

Little additional capacity for future antennas currently exists on the steel support frame at the top of the tank. Strengthening and modifications may be required if it is desired for additional telecommunication equipment to be mounted to the frame.

Some newer, heavier equipment mounted to horizontal rails (see photo #2) may be overstressing the frame in localized areas.

The attachment of the steel support frame to the top of the tank is minimal (see photo #3). It appears that the top of the tank shell is overstressed at bearing locations and localized strengthening of the tank shell at bearing points is likely required.

Larger telecommunication equipment is likely overstressing the catwalk handrails in many locations and the catwalk will need to be strengthened to adequately support the equipment.

The catwalk is bouncy under foot traffic and deflected downward at several locations and may require braces to stiffen the walkway, even if existing telecommunications equipment is removed entirely.

The handrails have defected at tall telecommunication equipment mounting locations (see photo #1) and the braces below the walkway do not appear adequate. Additional braces both below the catwalk and at the top of the equipment may be required to enhance the strength of the mounting configuration and reduce deflection.

4

Tripping hazards exist on the tank catwalk and should be eliminated (see photo #4). Tank and Appurtenance Description The Bedrock Drive elevated water storage tank is approximately 118-feet tall (based on a review of previous tower mappings) and is constructed using structural steel. The tank is supported by six equally spaced steel legs and concrete foundations (only the top of the foundation was exposed to view). The tank is laterally braced by diagonal steel rods. There are currently 19 appurtenances located on the perimeter of the tank catwalk (18 antennas). The tank catwalk is constructed as shown in Section 2 Sheet S2.0. The water tank currently has a steel telecommunication equipment support frame mounted to the top of the tank bowl. The frame is constructed as shown in Section 1 Sheet S2.0 which is located in Appendix B. There are currently 9 antennas located on the frame, plus the associated equipment. The frame has little additional capacity for future antennas. Please see Table 1 on Sheet S1.0 in Appendix B for more detailed information on telecommunication equipment currently mounted on the frame and to the tank catwalk. Findings and Recommendations I. Top Frame:

Telecommunication equipment on top of the tank bowl is located on steel support frame at the center of the tank. The frame is generally in good condition. a. The frame footprint is triangular with each flat approximately 13’-4” in length. b. The frame is constructed with galvanized steel angles. c. Two antennas are located at each corner of the frame (six total) and an

additional antenna is located at the midpoint of each flat. The equipment supplying the mid-point antennas is not located at panel points and may require strengthening.

d. The connection between the frame post bases and the top of the tank shell appears to be insufficient. Strengthening of the tank shell and increased connectivity at the frame post based is likely required.

e. It is not possible for the existing frame to support all of the equipment in the existing lease.

II. Catwalk: Telecommunication equipment mounted on the existing catwalk handrails is likely overstressing the handrails and strengthening will be required. a. The catwalk and handrail is framed with structural steel angles and plates.

Telecommunication equipment is typically mounted to vertical steel pipes that are attached to the tank handrails using U-clamps.

b. Strengthening the catwalk may require additional steel support either above or below the catwalk.

5

i. Kickers have been added below the catwalk in an attempt to strengthen the antenna mount to the structure. Because the kickers do not extend to the tank wall (photo #5) they are largely ineffective and should be replaced with properly designed/installed steel kickers.

c. It is likely that strengthening will be required because there are not enough corral posts to relocate all of the existing equipment from the handrails to the frame at the top of the tank.

Limitations Our findings and recommendations are based on visual observation only and no destructive testing was performed. All corrective details provided are schematic in nature and do not represent complete engineered drawings. Complete repair drawings should be provided by a registered Professional Engineer. Although an attempt was made to identify major deficiencies, it is possible that additional deficiencies may be found during the preparation of engineered repair drawings. Conclusions The structure supporting existing telecommunications equipment on the Bedrock Drive elevated water storage tank is generally in fair condition, with the exception of the catwalk handrails. However, the tank shell should be strengthened at post bearing locations. The primary structural concern is the inadequacy of the catwalk and handrails to support much of the telecommunication equipment as currently installed. The handrails and catwalk will need to be strengthened to support the existing equipment. The water tank does not have sufficient additional capacity to support the 33 antennas that have currently been leased without using the catwalk. Consideration should be given to replacing the top frame and catwalk handrail mounts with a properly designed and installed corral at the top of the tank. A standard 24-post

6

corral may not provide capacity for all antennas in the lease; consideration could be given to installing a custom corral with sufficient capacity. A combination of a corral and a strengthened handrail/catwalk could be utilized to adequately support all telecommunication equipment in the lease. The budget provided does not show the cost of a new corral. If you should have any further questions please do not hesitate to contact our office.
