e- NORTHERN STATES POWER COMPANY Director of NRR December 18, 1981 Page 2' As noted in Section 7 of the attached report, exemptions from certain requirements of Section III.G.2 in a small number of cases where compliance would be impractical or imprudent are requested. An additional deviation from the implementation dates in paragraphs (c)(2) and (c)(3) of Section 50.48 for the installation of new automatic fire suppression equipment

'is also requested. We believe these exemptions are justified based on the arguments presented in our report and for other reasons stated in reference (a). We also believe the deviations we have requested from the requirements of Section III.G.2 and the relief from the implementation schedule specified in Section 50.48 will not be detrimental to public health and safety.
