That's unlikely to be true. Standards commonly beget all kinds of bureaucracy and effort downstream. Sensible-sounding regulations (e.g. "we should certify that our city's water systems comply with all relevant EPA standards!") conspire with "no-cost-you're-already-meeting-this" standards to increase the burden of documentation, verification, certification and so on. And maybe that's fine! But the supposition that the EPA setting a standard relevant to tens of thousands of municipal water districts will generate zero costs for those municipalities glosses over how the bureaucratic wheels turn.
