In 2013, a workgroup was formed to re-write/edit the original document. This document is the product of the workgroup. The workgroup consisted of representatives from the drilling industry, the major grout manufacturers, and state agencies dealing with ground water. Monthly meetings were held for 13 months to revise the original 1996 technical guidance document. Some of the key changes include:
- A table (Table 1) that lists different types of wells, the regulatory agency, if regulated, and the applicable regulation or guidance (page 2).
- An appendix that contains associated links to the OAC or ORC (Appendix 2).
- An emphasis on hiring or at least consulting a contractor before sealing a well. (Any well owner can seal their own well.)
- The Preparation for Sealing section (pages 13-19) was expanded to include a table of possible concerns and the corresponding state or federal agency that may have information. A new Procedure Planning sub-section (pages 18-19) was created that lists all the items that should be in the plan before the well is sealed.
- The cement-based grouts section (pages 20-26) was expanded to include a discussion on situations where bentonite grouts are not effective due to water quality conditions in the well to be sealed.
- The General Sealing Procedures section (page 31) was expanded and the steps were numbered.
- The specific well sealing procedures for dug wells and bucket auger wells were separated because ODH has different sealing procedures for these types of wells.
