SUMMARY

OF REOUEST FOR APPROVAL OF PROCEDURES OF DREDGING SPOILS CONTAINING LOW LEVELS OF RADIOACTIVITY r

In accordance with the requirements of 10 CFR 20.302(a), Big Rock Point requests approval for the procedure of relocating Lake Michigan sediment, which contains low levels of radioactivity, from the plant discharge canal (an unrestricted area) to an onshore area specified by Corps of Engineers Permite No 88-56-143 and 87-56-185. Up to approximately 500 cubic yards of i

spoils would be relocated'each year for a ten year period. Calculated on a conservative basis, uncontrolled use of the proposed relocation sites will j

result in an insignificant dose to any individual member of the public of less than 0.06 mrem in the first year and less than 1.5 mrem integrated over a ten year period of annual dredging. These extremely small doses represent combined. exposure due to inhalation of dust, ingestion via drinking water pathway..and direct shine to persons walking on the spoils.

For reasons discussed in'the report, the dredgings will not support cultivated crops, so the food crop dose pathway 19 not represented.

Consumers Power Company concludes that the proposed relocation of dredged material does not pose a significant radiological hazard to the general public

.and workers. The spoils will be surveyed prior to release for public use in order to verify that radiation levels are not in excess of those calculated.

1.0 INTRODUCTION

l l

Consumers Power Company (CPCo) requests approval, pursuant to 10 CFR 20.302(a), to relocate sediment from the Discharge Canal (unrestricted area) at the Big Rock Point (BRP) Plant to CPCo property upland in a confined disposal area at the BRP site.

The i

500 cubic yards of sediment contains a maximum concentration of l.25 pCi/gm of radioactivity absorbed from liquid radioactive i

releases of licensed material. This application addresses specific E

information requested in 10 CTR 20.302(a).

2.0 WASTE STREAM DESCRIPTION Big Rock Point routinely disposes of liquid waste by discharging to Lake Michigan as allowed by 10 CFR 20.106 within the limits of 10 CFR 20 Appendix B. Table II and as controlled through plant Technical Specifications (Docket No. 50-155 Section 13.1). A fraction of the activity released is adsorbed on the sediment in the Discharge Canal. Due to changing lake level, and natural changes in lake bed contour, it is necessary to dredge the canal to ensure uninhibited flow to Lake Michigan.

The dredging 2)111 involve a ving between 250 and 500 cubic yards v

(191 to 382m of sediment from the canal to a " confined disposal area," as defined in Attachment One, on Consumers Power property at Big Rock Point. Permits No. 88-56-143 and No. 87-56-185 (Attachment One) allow dredging to be repeated on an annual basis as needed.

2.1 PHYSICAL AND CHEMICAL PROPERTIES OF THE SEDIMENT The material to be relocated is wet sand and gravel indigenous to the shoreline of northern Lake Michigan. The sediment is inert solid material composed mainly of silica.

There are no chemical hazards associated with this material.

2.2 RADIOLOGICA1. PROPERTIES OF THE SEDIMENT j

Radiological analysis of surface sediment samples scooped from various areas of the Discharge Canal have been performed by an

~

independent contractor (Teledyne Isotopes) and compiled in Appendix One.

These analyses include samples taken annually from 1985 through 1989 as part of Big Rock Point's Radiological Environmental Monitoring Program as well as ten (10) samples taken in June 1989 to ensure samples are representative of activity distributed throughout the canal. The results of these analyses provide a conservative estimate of the activity which may be contained in the sediment at the time of dredging. The total activity of the sediment is based on the average activity concentration encountered in surface samples (see Appendix One).

mil 289-0470A-BX01-NA01 1

y.

n E

U*

Principal.nuclides identified in the sediment are given in Table One.

Maximum gamma activity of the sediment is 0.9 mci in 500_ cubic yards 8

(382 m ).

Maximum Beta activity in the sediment is 7.1 aci in 500 i

cubic yards (as compared to 6.3 mci natural occurring Beta activity.

in lake sediment samples at the Ludington background sample station).

2.3-OPERATIONAL FACTORS The dredging of the canal is anticipated to take place between June and October 1990 and annually thereafter as necessary.

Dredging will be a two (2) to three (3) day operation occurring on day shif t (between 7 am and 5 pm).

For basis on estimated composition, i

concentrations and total activities, see Table One, its associated notes and Appendix One.

3.0 DESCRIPTION

OF PROPOSED DISPOSAL METHOD Sediment from BRPs Discharge Canal will be dredged by mechanical means and deposited on CPCo property at BRP in a " confined disposal area" above the ordinary high water mark for Lake Michigan as i

stipulated in the dredging permit (Department of the Army Permit Wo. 88-56-143, see Attachment One).

1 l

The potential disposal sites indicated on the maps in Attachment One I

will be well below the level of regulatory concern from a radiological l

standpoint, and will be open to the general public. Recreational fishing is allowed at the discharge canal and plans are being pursued for a nature trail through the woods near one of the disposal areas.

The proximity of the proposed nature trail to the Lake Michigan shoreline invites individuals to cross the disposal area heading

'toward the shore. Neither disposal area is normally frequented by workers, however the proposed addition of a nature trail may result in more use of the one area.

Sediment dredged from the canal will be graded to two (2) to four (4) inches thick in the disposal area. No specist record keeping, sampling or processing of the sediment and no additional quality control requirements will be pursued except that a thorough gamma-sensitive survey will be performed on the graded area prior to I

allowing public access.

Release for public access will be contingent upon confirmation that post-disposal area dose rate has not increased above pre-disposal area background, as defined by a criterion that pre-and post-disposal levels vary by not more than i 25%. The value of 125%

allows for temporal variations observed in monthly environmental TLD background data (reference 1988 Annual Environmental Report, April 17, 1989, for TLD trend plots).

Quality Control surveillance will be performed to ensure the dredge material is deposited in 'the location specified in the permit and graded accordingly. No control preventing future use of the disposal site in addition to present control of the owner controlled area of the BRP site will be pursued.

4.0 EVALUATION OF THE RADIOL 4CICAL IMPACTS OF SEDIMENT DISPOSAL Potential exposure pathways due to dredging and disposing of sediment from the BRP Discharge Canal include:

1) external exposure to the sediment during dredging,

2) groundshine in the disposal area,

3) inhalation of re-suspended isotopes from dried sediment blown by the wind, M11289-0470A-BX01-NA01 3

i L

6-t t

1

4) exposure from assumed infiltration and contamination of f

j groundwater, and

5) internal exposure from ingestion of food grown on the disposal site.

i L

The maximum exposure to workers will be to those workers involved in l

grading the sediment in the disposal area during the dredging o pe ra tion s.

The dose to these workers is determined as groundshine i

in the disposal area (exposure pathway 2).

.i Exposure from assumed infiltration and contamination of groundwater le of minimal concern in this case on the basis of location adjacent to Lake Michigan. There are no wells in either potential disposal area or between the disposal area and Lake Michigan (direction of groundwater flow). Exposure to the general public from activity released to Lake Michigan via this pathway is accounted for in Big Rock Point Semiannual Radioactive Effluent Release Reports based on data at the time of the original liquid radioactive releases from which the dredged activity is derived. The activity adsorbed on the sediment removed from the canal and re-released to Lake Michigan via this pathway will not increase those original exposure estimates.

1 Even though these doses have been accounted for previously, estimates l

due to potential radionuclide release from the spoils is presented in Table Two.

Internal exposure from ingestion of food grown on the disposal site is not of concern due to lack of nutrient content within this washed stone / gravel / sand mixture. The disposal sites also are unprotected from harsh offshore winds. Cultivatable vegetation is not supported in either area.

-t Conservative calculations of external exposure during dredging, j

liquid pathways, groundshine in the disposal area, and inhalation of dried windblown sediment are detailed in Appendix Two and summarized in Table Twn.

5.0 ENVIRONMENTAL IMPACT ASSESSMENT l

Approval of this application is needed to enable BRP to dredge the i

discharge canal ensuring uninhibited flow to Lake Michigan.

Alternatives to the proposed disposal method include return of the sediment to Lake Michigan, an exposure pathway for which radiological impacts have already been assessed. However, the Department of the Army Permit (Attachment One) stipulates the material dredged be deposited on land.

A second disposal alternative on the basis that BRP is receiving radioactive material via dredging in the unrestricted area, is to dispose of the material as radioactive vaste via shipment to a licensed radioactive vaste disposal facility. This is a costly alternative as well as an inefficient use of limited burial space.

Disposal of 500 cubic yards of sediment via this alternative, would require shipment of 1800 55-gallon (7.5 ft*) drums. The weight of l

each full drum of approximately 735 lb (based on the density of 8

excavated sand and gravel, dry of 98 lb/f t ).

With shipment weights limited to 40,000 lb per shipment, at least 34 shipments would be 8

required. Present shipping costs are $58/ft plus $1200 per shipment transportation cost. Therefore, the cost of shipment of canal sediment is approximately $824,000 (not including analytical or packaging cost, or cost of 1800 drums). This is an enormous cost to incur on a yearly basis to dispose of less than 0.9 mci of activity.

A third disposal alternative involves disposing of the sediment as proposed in this application with a esvering of clean sand over the disposal area. This added effort is not warranted on the basis of minimal exposure due to the unburied sediment as presented in Section 4.0.

The most acceptable alternative would be to allow dredged material to settle to the lake bottom beyond the channel area. This alternative has the potential to release up to the approximately 0.9 mci of total activity into the water at time of dredging. Given that this 0.9 mci is approximately 1.2% of normal annual release of similar nuclide mix, doses would be roughly 1.2% of the annual dose for liquida presented in Table Three. Although this is a low dose option, our permits require placement of spoils on dry land.

All work related to dredging and redeposition of the sediment as proposed in this application, will be performed at the BRP site which is relatively secluded (nearest residence 1.1 mile SW; nearest industry 0.6 mile E).

Noise due to this activity will not affect the general public. Big Rock Point is located off a major highway, therefore delivery and release of equipment will have no impact on normal traffic in the area.

SUMMARY

Consumers Power Company is requesting approval, pursuant to 10 CFR 20.302(a), for procedure of locating sediment from the Discharge Canal at the Big Rock Point Plant to property upland for unrestricted public use. Dredging of the Discharge Canal is necessary to ensure uninhibited flow from BRP to take Michigan. The sediment being relocated contains trace amounts of licensed material (Sr 90, Mn 54, Co 60, CS 134 and Cs 137) adsorbed from liquid radioactive releases dispatch in accordance with 10 CFR 20.106 and within the limits of 10 CFR 20 Appendix B. Table II. The relocation and redisposition of activity poses a negligible radiological hazard to the general public or to workers frequenting the area (maximum 0.056 mrem per dredging).

From Mark's standard Handbook for Mechanical Engineers (pg 18-12)

• The amount of suspended matter in normal city air = 1.37 mg/m 3

and the amount of suspended matter in manuf acturing plant =

Using-the value for suspended matter in normal city air would be conservative considering that fresh clean air blows off Lake Michigan across the disposst site to re-suspend isotopes from the dried sediment. Assuming a gentle breeze throughout the year since individuals would not remain in the area if higher winds blowing the sand were present. = For added conservatism the value for suspended matter in a manuf acturing plant is used.
