This morning we read that it might take EPA a bit longer than anticipated just a few days ago to bless the new ASTM standard for environmental site assessments. Why? Because at least one of the lawyers who spent countless hours developing the new standard is criticizing EPA's plan to allow adherence to either the old standard or the new standard and that is going to require a more time consuming administrative process than EPA had anticipated.
That lawyer, Larry Schnapf, seems to have a very valid point. If the experts agree that the old standard needed revision, and they did, isn't it counterproductive for EPA to continue to bless the old standard? In fact, if the definition of "standard" is "an idea or thing used as a measure, norm or model" (and it is), how can you have two standards for the same thing?
In any event, regardless of what EPA does, and how long it takes, as I wrote last week (https://insights.mintz.com/post/102hkn3/your-standard-environmental-site-assessment-may-still-be-skipping-over-pfas), you can and should collaborate with your environmental professionals now on the environmental site assessment scope that makes sense for you.
Any environmental professional you should be dealing with will be willing to provide you an environmental site assessment that meets the requirements of both the old standard and the new one.
