MEMORANDUM FOR: Ross A. Scarano, Chief Uranium Recovery Licensing Branch 9
FROM:
Gregory G. Eadie

P Uranium Recovery Licensing Branch
SUBJECT:
GA0 CLEARANCE OF 40 CFR PART 190 ORDERS On February 20, 1981, Pat Woolley and I met with Norman F. Heyl, U.S.
General Accounting Office (GA0), to resolve the GA0's concern that the 40 CFR Part 190 orders mandated the implementation of Regulatory Guides 4.14 and 4.15.
Upon review of this matter with R. Fonner and K. Cyr of ELD, it was concluded that some of the language of the 40 CFR Part 190 orders had to be changed and are sumarized as follows:
o The quarterly reports shall be submitted using the format in the attached Table, " Sample Format for Reporting Monitoring Date."
o The licensee shall submit, for NRC review and approval, specifica-tions for a quality assurance program following Regulatory Guide 4.15; or the licensee may provide specifications for an equivalent quality assurance program.
o' The licensee shall follow the lower limits of detection (LLD) contained in the attached Table, " Lower Limits of Detection (LLD) for Sample Analysis."
Upon receipt of the revised ordert, a meeting will be scheduled with GA0 to expedite their approval of the issuance of the 40 CFR Part 190 orders.
