Northern Indiana Public Service Company Bailly Generating Station Nuclear 1 - Docket No. 50-367

Dear Mr. Boyd:

Please find enclosed forty (40) copies of " Supplementary Infor-mation on Driven H-Pile Foundations. " This information supplements that sent to you on September 26, 1978, in response to RSP 362. 6 contained in Mr. Vassa11o's letter of June 22, 1978.

This supplement includes the results of 18 additional borings, three additional pile load tests, and an extensive study on pile heave.

The driving criteria to be used for the installation of all piles in all areas to assure an acceptable bearing capacity are included.

We would appreciate your early concurrence in our proceeding with production piles.

Very truly yours,

/
