Final Radiological Survey Plan May 21, 1993 for AMS and Surrounding Areas I.
Purpose The purpose of this radiological survey is to determine whether there exists any contamination from AMS operations that would pose a health and safety concern outside of the AMS facility.
II.
Coordination Meetings have been conducted with concerned Cleveland elected officials, Cleveland City staff and Northeast Ohio Regional Sewer District staff to discuss the AMS facility, review the survey plans and obtain their input.
Their input has been incorporated into this plan.
Assistance has been secured from Northeast Ohio Regional Sewer District and Cleveland City personnel to gain access to sewers, basins and sewage treatment facilities and to assist in performing surveys and sampling those areas.
The AMS Radiation Safety Officer'will provide access to areas under AMS' control and any necessary radiation protection measures for access to those areas.
The Cleveland Public Services, Water Pollution Control and Public Utilities Departments will assist the survey team with access to industrial facilities and roofs, and residential buildings and roofs, and provide secure facilities to support the Mobile Laboratory.
Federal, State and local elected officials will be notified of the survey and close out meeting plans.
Coordination has occurred with the City of Cleveland (elected officials and staff), Cuyahoga County Department of Health, Ohio Department of Health, ar:d Northeast Ohio Regional Sewer District.
Region III Public Affairs and Government Liaison staff will assure appropriate notifications are made.
Federal elected officials will be notified through the Office of Congressional Affairs.
A notification to local residents and businesses will be delivered door to door by Cleveland City personnel to assure that the local neighborhoods are aware of the NRC activities.
Region III has reviewed that notification. A press release will be issued by Region Ill announcing the time and location of the close out meeting for the surveys.

Personnel The personnel conducting the survey will consist of two inspectors and one technician from the Region III staff.
In addition to NRC personnel, the Ohio Department of Health (00H) has committed staff support to the survey team.
A separate inspection effort by two other inspectors will be concurrently conducted (See Attachment) within the AMS facility to evaluate release pathways and radiological conditions.
That effort will l
be assisted by an NMSS Section Leader.
A Region III Branch Chief will conduct the public close out meeting.
IV.
Equipment The Region III Mobile Laboratory will be used for the counting of soil / sludge / water samples collected during this inspection.
MicroR 1
meters, Nal crystals, and pancake GM probes will be used for direct radiation surveys.
Sampling supplies will be obtained from the Region III lab.
Any apparatus necessary to sample sewers will be provided by the NE0RSD and Cleveland City staff.
l V.
Radiological Surveys A.
Direct radiation surveys will be condJcted over the following areas:
- 1. At two locations approximately 0.5 mile west of AMS to establish a local background.
This will include Collinwood High School and one other location identified by the City of Cleveland.
- 2. Along London Road 1/4 mile north and south of the AMS facility.
- 3. Along the railroad tracks 1/4 mile east and west of the AMS facility.
- 4. Along Wickford Court, along Wayside Road between Wickford Court and Roseland Road, and along Roseland Road between Wayside Road and Avalon Road.
5.
Over the on-site grounds of the AMS facility, and at all gutter downspouts.
Particular attention will be paid to the external surfaces of the AMS facility to assure that they will be in compliance with the revised 10 CFR Part 20 (100 mrem / year in unrestricted areas).

- 6. Over the grounds and at the gutter downspouts of representative industrial and residential properties within 500 feet of the AMS hot cell location.
This will in-lude-the first two residences north of Mandalay Avenue or; London Road, Alhambra Road and Rudyard Road.
In addition, the grounds of the followir.g residences will be surveyed:
936 London Road 901 Alhambra Road 928 Alhambra Road 949 Alhambra Road 916 Rudyard Road
- 7. On representative industrial roofs within 500 feet of the AMS hot cell location including any air intake housings.
- 8. On representative residential roofs and gutters within 500 feet of the AMS hot cell location.
- 9. Over the grounds of the park, the swimming pool, the tennis courts, the park facilities, and the baseball field west of AMS on Mandalay Road.
- 10. In the manhole and sewer lines on-site at AMS and in the manholes, road way gutter basins, and sewer lines off-site and downstream of AMS.
This will include two road way gutter basins along London Road north of the rail
.d tracks, two road way gutter basins along London Road south of the railroad tracks, road way gutter basins at the corner of Alhambra Road and Mandalay Avenue and at the corner of Rudyard Road aiid Mandalay Avenue, and three manholes to the London Road sewers downstream (north) of the AMS outfall.
- 11. At the Easterly Plant in areas that the NE0RSD identifies as solids collection points.
Any detected cobalt-60 off the AMS property will result in a revision of the survey plan to address the scope and nature of that finding.
Most surveys will be conducted using microR meters or Nal crystals.
However, GM pancake probes will be employed in those circumstances in which they would be signific -tly easier to handle.
The GM probes may also be used for cc. 'irmation of any areas giving elevated readings with microR meters.
B.
Sample Collection - At this time it is estimated that, as a minimum, the following samples will be collected and counted in the Mobile Lab.
Preliminary tests show that a one hour count of a 500 ml geometry will generate a minimum detectable activity of <1 pCi/ gram.
The NRC safe release level for cobalt-60 in soil is 8 pCi/ gram.
) May 21, 1993:
1.
Two soil samples from the locations approximately 0.5 mile west of AMS ider,tified by the City of Cleveland to establish a local background.
These will be the same locations where background surveys are performed pursuant to.l. above.
2.
Sludge samples from the. basins, manholes, sewers, and sewage treatment systems, at locations described.in-
- 10. and ll 'above.
~
3.
Several soil samples consisting of on-site samples,..
residential samples and samples from the bordering industrial sites.
Samples will also be taken at any-location that yields elevated readings on-the survey-equipment.
4.
A water sample will be taken from the public swimming pool, if it is filled.
If it exists, used swimming pool filter media will be obtained and analyzed.
A soil sample will be taken from the public baseball field.
