The case of the missing well logs
EPA personnel: We don’t have them, and we don’t know if they ever existed

EVART – What is the reason for the Environmental Protection Agency’s refusal to examine drilling logs for 36 deep wells in the vicinity of the proposed Michigan Potash Company facility? That has been one of the more persistent questions being asked about the project.
According to the EPA, the agency isn’t in possession of any such logs, and they may never have existed.
A misunderstanding apparently arose, according to a source within the EPA, during a series of phone conversations between EPA personnel and a caller who was making inquiries regarding the integrity of the layer of rock the that would confine non hazardous liquid waste deep under sources of drinking water.
The operations of Michigan Potash Company will require two types of injection wells: class III wells to inject water into potash deposits, dissolve the potash and carry it to the surface for removal, and class I wells for the disposal of water containing too high a concentration of unwanted solutes for it to be viable for continued potash extraction.
The non hazardous waste – water containing the same minerals currently mixed with the potash deposits – would be injected more than 5,000 feet into the ground, far below the 620-foot depth of the lowest underground source of drinking water.
During the phone conversations with a caller, EPA personnel said that much of its information regarding old wells in the area came from information from the state of Michigan including, possibly, information from well logs. From those conversations the caller, according to the EPA, erroneously concluded that government personnel possessed undisclosed well information. In fact, the EPA has no such well logs in its possession and doesn’t know if such logs exist.
Jennifer Ostermeier, a public affairs specialist with the EPA, said agency personnel identified all wells within a two-mile area of review surrounding the Michigan Potash Company property. All wells were plugged or constructed in such a manner that will prevent waste from breaching the rock confining area and contaminating the drinking water.
Answers to well log inquiries and other questions can be found on the EPA Web site, www.epa.gov and in the EPA’s document Response to Comments on Draft Class I Non-Hazardous Permits in Osceola County, Michigan, Issued to Michigan Potash Operating, LLC (Permit Nnmbers MI-133-11-0004, 0005, 0006).
Also, Michigan Potash will be hosting a town hall meeting March 7 at the Osceola County Fairgrounds in Evart. Company personnel will be on hand to answer questions at the meeting which is slated to run from 6 to 9 p.m.
