Helpful Tips Based on Participation in an Ohio EPA Virtual Site Visit

In our July 2020 newsletter, we included a brief article regarding Ohio EPA’s pilot program on the use of virtual site visits (VSVs) for select categories of inspections. This month, based on our recent participation in an Ohio EPA virtual site visit, we are providing helpful hints for participation in one.

EPA Turns 50 This Year

On December 2, 2020, the Environmental Protection Agency (EPA) will celebrate its 50th birthday. Nearly 50 years ago, on December 2, 1970, President Richard Nixon created EPA by executive order to consolidate in one agency a variety of federal research, monitoring, standard-setting, and enforcement activities to ensure environmental protection across the country. Eight years prior, Rachel Carson, an inveterate birdwatcher published Silent Springs on the indiscriminate use of pesticides and the fear that without control, fewer species of birds would be singing each spring. Who can forget our own Cuyahoga River catching fire in 1969? The first Earth Day took place on April 22, 1970 in what was considered by some the start of the modern environmental movement. Who knows what the next 50 years will bring for EPA and the environmental movement, but no one can argue that the creation of EPA has not been good for this country and the world.

DATA déjà vu?

Have you ever received an agency’s request for additional investigation and thought, “surely we’ve done this before?” You are not alone. Particularly on “lower priority” and long-running sites, involved parties can easily lose track of what has been done orver the years. Client, agency, and consulting staff turnover can make this even more likely. Cox-Colvin’s Data InspectorTM provides a solution to this problem, as demonstrated by several recent projects.

Michigan PFAS Groundwater Cleanup Criteria Revised to Reflect Newly Added State MCLs

With the federal government lagging-behind in the establishment of regulated standards for per- and polyfluoroalkyl substances (PFAS) substances, the Michigan Department of Environment, Great Lakes, and Energy (EGLE) recently promulgated its own state drinking water standards for seven per- and polyfluoroalkyl substances (PFAS). The PFAS drinking water standards, also known as maximum contaminant levels (MCLs), took effect on August 3, 2020. How will the new MCLs effect the Michigan generic groundwater water cleanup criteria?
