Dear Mr. Davis:

On August 3, 1987, we informed your office through telephone and written followup reports that a portion of the north outside fire protection ring header had been isolated due to what appeared to be a leaking fire hydrant. Upon further investigation, it was determined that the leak was, in fact, in, the potable water supply piping that runs immediately adjacent to the fire protection piping in this area. The fire protection ring header was returned to service at 1218 hours0.0141 days <br />0.338 hours <br />0.00201 weeks <br />4.63449e-4 months <br /> on August 4, 1987.

Respectfully, W.G. Smith, J
