Dear Mr. Strosnider:

On January 16, 2001, representatives from USEC and the NRC Staff met at NRC headquarters todiscuss the Environmental Compliance Status Report (ECSR) contained in Volume 3 of the PGDPand PORTS Certification Applications. As a result of this January meeting, USEC committed (Seethe Reference) to provide copies of the PGDP and PORTS Quarterly Radiological MonitoringDischarge Reports for plant outfalls. Enclosures 1 and 2 provide the first-quarter calendar year 2006reports for PGDP and PORTS, respectively.

Should you have any questions or require additional information, please contact Mark Smith at (301)564-3244. There are no new commitments contained in this submittal.

NOTES

Weekly concentrations and loadings with quartedy summaries are presented for Gross Alpha Activity, Gross Beta Activity, Technetium-99 (beta) Activity and TotalUranium Concentration. These figures are based on seven-day composite samples and measured flows at each outfall except at Outfall 005. Since Outfall 005historically had no discharge, there is no composite sampler there and effluent data is based on grab samples and manual measurements taken when there is anactual discharge.

Quarterly concentrations are presented for Americium-241, Neptunium-237, Plutonium-238, Plutonium 239 and Plutonium 240. (All of these are transuranics.Plutonium 239 and Plutonium 240 activities are reported as a combined activity because they emit substantially identical radiation.) These figures are based onquarterly grab samples.

Weekly concentrations that are below the Minimum Detectable Activity (MDA) or Laboratory Limit of Detection (LLD) are indicated by a "less than" (<) prefix aheadof the numerical MDAILLD. MDAs vary somewhat from day to day and from outfall to outfall depending on interferences present and other conditions.

Weekly loadings that correspond to less then MDA/LLD concentrations are calculated based on the MDAILLD value and prefixed with a "e except as follows:Technetium loadings at Outfalls 002, 004, 005, 009, 010, and 011 are presumed to be zero unless actually detected, based on the historical absence oftechnetium In these outfalls. These loadings are coded as "AA" unless actually detected.

Loadings are not calculated for transuranics because measurable transuranic concentrations are not normally present in any USEC-leased outfall.

AA indicates no detectable concentration.

AL indicates no flow during the sampling period.
