Program Background
In 2005, Ohio legislature enacted ORC 3714.071Established funding mechanism for conducting ground water monitoring at licensed C&DD facilities operating before April 15, 2005.
The fund may not be used to pay for ground water monitoring activities required to comply with rules adopted under
ORC
3714.02
Authorized expenditures include installation of ground water monitoring wells, GW sampling, and laboratory analysis

pHGI ObjectivesEvaluate
the potential for a release of C&DD-derived constituents to ground water downgradient of the limits of debris placement.Evaluate the adequacy of the ground water monitoring network for early detection of a release to ground water.

Use of ORC 3714.071 Funds
Facility has potential to impact GW but no GW monitoring, and thus could benefit from installation and sampling of additional wells using ORC 3714.071 funds.Facility has an
inadequate
GW monitoring network for
early
detection of a release and could benefit from installation and sampling of additional wells using ORC 3714.071 funds.
pHGI - ConclusionsSlide18
No additional action needed
Facility has little or no potential to impact GW and no GW monitoring, and thus no need to install wells using ORC 3714.071 funds.Facility has an adequate
GW monitoring network for early detection of a release but no indication of impact to GW.
pHGI - ConclusionsSlide19
Facility with GW monitoring and may be impacting GW –
Owner/Operator needs to conduct a GW assessment.Consensual or Unilateral Orders to conduct an Assessment
