A March 2001 letter from Water Resources Consulting LLC to the Washington State Department of Ecology raises concerns about a proposed NPDES permit modification for SeaTac Airport, arguing that the draft permit gives the Port of Seattle a 'blank check' to discharge pollutants at unspecified locations into unnamed water bodies without adequate public oversight. The letter also criticizes the airport's stormwater monitoring reports for obscuring potential water quality violations by mishandling hardness data used to evaluate dissolved metals concentrations. The author urges the Department of Ecology to require specific discharge locations and proper concurrent hardness reporting before issuing the modified permit.
