July 12, 2020 Mr. Jeff Musil Project Manager John Burns Construction Company 17601 Southwest Highway Orland Park, IL 60467 RE: Streeterville Thorium Monitoring Results – Small Cell Site

CDPH Permit No.: CDOT1250968 Permit Address: 401 N. McClurg Ct., Chicago, Illinois

AECOM Project No. 60616106 Dear Mr. Musil:

Pursuant to conditions specified in the ROW form (attached) issued by the City of Chicago Department of Public Health (CDPH), radiation monitoring was required to be performed at the above referenced site. AECOM Technical Services, Inc. (AECOM) provided the required radiation surveillance on June 17-19, 22 and 24, 2020 for excavation required to install fiber and power conduit for a small cell site at 401 N. McClurg Ct. (refer to map included with ROW form).

Surveying was performed in an open trench cut into the right of way near the intersection of McClurg Ct. and North Water St. Surveying was also performed in a pole foundation excavation at the southeast corner of the intersection. Refer to the attached photographs and drawing attached to the CDPH form for the approximate location of the excavations. The trench excavation was approximately 3-feet wide, 150-feet long, and excavated to a depth of 32-inches. Screening was performed every 15-feet of trench at 12-inch depth intervals for a total of 14 sections (see attached drawing and the gamma results table). The pole foundation was approximately 3 by 3 feet and excavated to a depth of approximately 10 feet.

The monitoring did not indicate that the fill soils were above the removal action level established by the U.S. Environmental Protection Agency (USEPA) for the Streeterville area of Chicago. The USEPA removal action level for Chicago’s Streeterville area is 7.1 picocuries per gram (pCi/g) total radium (Ra-226 + Ra-228). Gamma radiation count measurements for the project were recorded using a Ludlum Model 2221 survey meter and a shielded 2 x 2 inch Nal probe (Model 44-10). For the instrument used the gamma count threshold indicative of the 7.1 pCi/g removal action level is 6,818 (S/N: 326726) counts per minute (cpm) shielded utilizing a short cord and 4,991 cpm shielded with a long cord. The field instrument fill soil background measured nearby was 2,050 cpm long cord and 2,800 cpm short cord.

Field gamma measurements within the excavation openings did not exceed the instrument thresholds previously stated and ranged from 1,560 cpm to a maximum reading of 3,040 cpm shielded. Based on field observations there was no indication of the presence of radiologically contaminated fill and/or an exceedance of the USEPA removal action level of 7.1 pCi/g total radium. A copy of the CDPH form, photographs and the tabulated gamma results are included as attachments.

As part of the permit conditions, a PDF copy of this letter will be forwarded to Terry Sheahan (CDPH) and Verneta Simon (USEPA) to fulfill the requirements of the CDPH.

Please note that for some locations, additional health and safety procedures may be required by law.

Please complete the following:

I have reviewed and understand the documents, maintained by CDPH, regarding environmental contamination of the site and adjacent right-of­way. Further, I will ensure that all work at the subject site and adjacent right-of-way, and any monitoring required including but not limited to radiation monitoring. wiJI be performed in a manner that is protective of human health and the environment and in compliance with all applicable local, state, and federal laws, rules, and regulations, especially those pertaining to worker safety and waste management. I will ensure that the results of any radiation monitoring and/or surveying conducted shaJI be provided to the CDPH and the United States Environmental Protection Agency within two (2) weeks of their completion. If any elevated levels of radioactive material are detected, I will immediately contact the United States Environmental Protection Agency at (800) 424-8802.
