Dear Mr. Muller:

g g

y The draft environmental impact statement for " Crystal River Unit No. 3 and Supplements No. 2 and 3-to Environmental Report / Volume 5" which accompanied your letter of September 11, 1972, has been received by the Department of Commerce for review and comment.

The Department of Commerce has reviewed the draft environmental statement and has the following comments to offer for your consideration.

The statement adequately describes the expected impact of the proposed project on the aquatic resources.

Our comments are directed to specific areas that require further discussion and/or explanation.

2.6.2.

Aquatic Ecology 2.6.2.1.

The vital role of nursery areas in the con-tinued productivity of these species and shrimp, is well-documented and should be mentioned.

Commercial and Sport Fishing Page 2-54.

Although shrimp are not taken commercially in Citrus County waters for human consumption, there is a commercial bait-shrimp fishery that should be discussed.

Bait-shrimp are not sold by the pound, but as individual shrimp.

Surveys of the bait-shrimp fishery in Florida were not begun until 1963.

Citrus j

County statistics from that year through 1970 are 1

given below:

Num ber of 1

Year Individual Shrimp Value 1963 3,113,030 39,241 1964 3,826,615 43,055 1965 944,347 12,407 1966 549,550 9,192

)

1967 8,079,000 88,746 1968 10,413,450 124,297 1969' 7,824,500 89,078 1970 12,123,000 187,266 Shrimp are the most popular "all-around" bait in Florida, and the rapid growth of salt-water sport fishing is certain to place increased demands on the bait-shrimp fishery.

Considering declining yields of this fishery elsewhere along the coast, caused in great part by man-made alterations of the estuarine habitat to satisfy various desires of a bourgeoning population, the Citrus County fishery should become more important with each passing year.

Page 2-55, In making a comparison between the commercial catches off the west coast of Florida and Citrus County, it should be noted that fish and shellfish (shrimp) originating in the waters of Citrus County move up and down the coast and contribute in varying degree to catches of other coastal counties.

The radiological monitoring program appears to be adequate.

However, considering the data produced by field surveys (pp. 2-24 to 2-56), more details on the selection of species for radiological analysis would be desirable.

Adverse Effects Which Cannot Be Avoided.

Page 7-1.

Seventh paragraph.

Recent studies, made by St. Petersburg Beach Laboratory

's

, biologists, showed the average volume of zooplankton present in Crystal Bay area waters to be 0.25 milliliters per cubic meter.

The present flow of water through the plant is approximately 600,000 gallons per minute.

With the addition of Unit No. 3, the flow will be approximately 1,250,000 gallons per minute.

Assuming total kill of zooplankton, dead organisms will accumulate at a rate of about 2 cubic yards per day.

By weight, this amounts to a daily loss of 1.4 tons of zooplankton.

To more graphically show the magnitude of the volume of water required for the plant's cooling system, a comparison was made of this need with the quantity of water enclosed within natural geographical boundaries south of the site.

Spoil areas adjoining the intake channel extend for slightly more than 4 miles into the Gulf.

Long Point lies 6 miles to the south (see attached chart).

The waters shoreward of a line from Long Point to the outermost spoil bank comprise a semi-enclosed area encompassing oyster bars and the mouth of the Crystal River, and has a volume of about 21 billion gallons. With Unit No. 3, in operation, the plant will require approximately 1,728 million gallons of cooling water per day, or the equivalent of all the waters in this " bay" every 16 days.

In view of the foregoing, we do not agree that the loss of planktonic forms during plant operation will have a negligible effect on the overall productivity of the in-shore marine ecosystem.

The basis for arriving at this conclusion should be thoroughly discussed, together with presentation of substantiating data.

Angs,1 fish Spanish Mackerel Page 5-31 Productivity Considering the proposed location of the plant, it was note-worthy that the potentially overriding hydrometeorological l

impact of storm surge was overlooked.

The statistics cited with regard to hurricane frequency appeared essentially correct.

However, it is suggested that these data be further examined.

Section II, Item D2, indicates a small probability of hurricane occurrence in Florida--ranging from zero to five in individual years and averaging only 1.6 per year during the period 1885 to 1958.

This occurrence index cannot be disputed.

However, a space / time stratification of similar data w uld suggest a higher probability of hurricane produced meteorological impacts.

For example, during the period 1900 to_1969, the United' States (south of 350 N) experienced 19 hurricanes which l

had central pressures <

950 millibars at landfall.

Sugg has. developed a mean profile of these storms with probable 1 ugg,

-5, occurrences of storm surges of 16 feet, although heights up to 23 feet have been recorded.

More important, a rectangular plot of the profile exhibits a roughly normal curve of lateral extent of storm surge versus height.

As an illustration, eight-foot surges would have a hori-

^

zontal extent of approximately 100 NM--mostly south of the hurricane " eye".

Therefore, it is suspected that the frequency of important j

storm surge effects on a plant situated on an outer bank island in southern Florida would be statistically signi-ficant.

This may suggest that the section on Postulated Accidents should consider hydrometeorological effects.

We agree with the AEC staff's computation of the average annual relative concentration as applied to routine releases.

We are unable to evaluate the AEC staff's analysis of the impact of accidental releases of radioactivity because the meteorological ascumptions, the resulting relative concen-tration, and the probability of occurrence of such a concentration is not specified.

We hope these comments will be of assistance to you in the preparation of the final statement.
