The OMA this week submitted comments regarding the U.S. EPA’s Draft Ambient Water Quality Criteria Recommendations for Lakes and Reservoirs of the Conterminous United States. The OMA outlined serious concerns regarding the proposed use of the draft recommendations, as well as some of the assumptions underlying the recommendations.
The OMA stated that the draft recommendations, if pursued, “should not be issued as Clean Water Act Section 304(a) criteria, but rather as guidance for the limited purpose of evaluating whether nutrients may be a cause of a confirmed use impairment in a lake or reservoir, and only after the models are revised to address their overly conservative assumptions.”
