04.01.2009

On March 18, 2009, staff from the IDEM Office of Land Quality (“OLQ”) presented Non-Rule Policy Document (“NPD”) WASTE-0053, Drilling Procedures and Monitoring Well Construction Guidelines to the Solid Waste Management Board. NPD WASTE-0053 may be put into effect by the OLQ 30 days after presentation to the Board. The purpose of NPD WASTE-0053 is to assist drillers, geologists, and contractors to properly drill and construct borings and monitoring wells. NPD WASTE-0053 compiles in one document existing procedures for proper boring and monitoring well installations provided by state statutes and rules (IC 25-17.6, IC 25-39, 312 IAC 12, 312 IAC 13, and 329 IAC 9) as well as OLQ Remediation Services Branch guidance.

NPD WASTE-0053 provides procedures and clarifications for boring and monitoring well installations including: drilling methods; use and installation of bore holes; sampling and analyses of borings and monitoring wells; monitoring well construction including the proper use and installation of well casing, screen, filter pack, filter pack seal, grouting, and finished well casing; proper monitoring well development; proper management of drilling fluids, cuttings, and development water; decontamination of drilling equipment; submission of drilling data to the OLQ; and boring and monitoring well abandonment and plugging procedures.

Additional information regarding NPD WASTE-0053 may be obtained by contacting Larry Studebaker, Section Chief, IDEM OLQ at (317) 234-0991.
