Wilgus Vice President, Nuclear Operations Florida Power Corporation P. O. Box 14042 St. Petersburg, Florida 33733 Re: Notice of Violation Florida Pown Corporation-Crystal River NPDES Permit No. FL0000159

Dear Mr. Wilgus:

Your letter dated January 5,1984, cancerning non-compliance with this permit, has lef t unanswered several questions.

Your permit limits the rise in temperature (delta T) to a three hour limit of 17.50F and a one hour limit of 21.00F. The temperature rise problem must have been evident before 2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> December 26, yet no apparent action was taken for over four hours. Also, delta T dropped after 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br />, although cleaning did not start until over two hours later. Finally, the word ' cooling" in paragraph 2, line 4, appears to not belong in the sentence.

Therefore, we request that you provide this office with detailed answers on these questions:

1. Why did it take so long to clean the intake screens af ter the excessive rise in temperature was noticed? What actions did Florida Power Corporation take once the problem was noted?

2. Why did the rise in temperature drop after 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br /> but prior to cleaning?

3. How should the sentence in paragraph 2 read?

In addition to these answers, please provide specifics on any plans to prevent recurrence of these violations in the future.

Until such time as you achieve cmpliance with all conditions of your NPDES permit, you are considered to be in violation of and subject to enforcement action pursuant to Section 309 of the Clean Water Act.
