Undeveloped property will not have the same exposure possibilities as the site of an oil refinery. A residence will not generate the same volume or type of waste as an auto repair shop. Grazing pastures will not have the pesticide exposures associated with farmland. Historic records provide a means for tracking property usage. A minimal ASTM search goes back to when the property was first developed . agricultural use or to the year 1940 around the time of World War II when technology and the volume of hazardous waste began to esca-late whichever is earlier . further back in time reasonably ascertainable and likely to be most useful. For instance property development may go back to the 1600s. Yet locating historic sources four hundred years back in time is not reasonable nor is it likely to be useful. In these instances it becomes a judgment call. Further complications may occur where historic records are unavailable to the public or are not obtainable within a reasonable time frame . 20 calendar days or cost. If the records have been filed chronologically rather than by property or facility a year-by-year search would be reasonable. Searching records that in context are not likely to provide meaningful information may be a waste of time. Although the All Appropriate Inquiries Rule goes back to when the property was first developed the only mandated search is that of environmental liens which were filed only after the enactment of the 1980 Superfund Act. The Rule also does not require any specific historic documents nor a minimum number of documents be reviewed. The decision as to the extent of a historic usage search is discretionary. A minimum search interval should be no less than five years. Yet in some cases the gap may be greater due to limitations
