June 1, 2006

US-EPA, Region 4, SESD, Athens, Georgia

[ Disclaimers | Copy of Signed Notice ]


The purpose of this notice is to announce interim approval ASTM International Method D 888-05, for measuring dissolved oxygen concentrations under the National Pollution Discharge Elimination System (NPDES) Program. This approval applies only to NPDES discharges which are physically located in EPA Region 4. This approval does not apply to NPDES discharges in other EPA regions. To determine the status of ASTM International Method D 888-05 in other EPA regions, interested parties should contact the appropriate EPA region.


The subject method has been given a thorough review by the Statistics and Analytical Support Branch (SASB) of the US EPA Office of Water for use in the National Pollutant Discharge Elimination System (NPDES). The method was determined to be acceptable and the formal approval process has been initiated. It is anticipated that this process will take between 18-24 months. In view of this delay, the Office of Water issued a memorandum dated January 3, 2006, recommending that each EPA Region grant interim approval for the use of the method (memo attached).


In accordance with 40 CFR 136.5, Approval of Alternate Test Procedures, and the recommendation of the Office of Water, US EPA Region 4 is hereby granting interim approval for the use of ASTM International Method D 888-05 for the measurement of dissolved oxygen. This approval is effective the date of this notice and applies only to laboratories which analyze samples from NPDES discharges within the 8 states of Region 4 (Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, and Tennessee). Laboratories analyzing samples in other Regions must contact the specific Region to determine the approval status of the method within that Region.
