In 2005, the Legislature passed LD 1643 in 2005 "An Act to Clarify and Harmonize State
Policy on Groundwater Management." In June 2005, the Governor signed this bill into law as
Public Law 2005 c. 452. This law directs the Land and Water Resources Council to conduct a
comprehensive review by November 2006 of Maine's regulations governing ground water
withdrawals through the formation of a work group. The primary charge to the group was to
identify any changes in state law needed to ensure a consistent, integrated and scientifically
sound state policy that ensures that the withdrawal of groundwater does not have an undue
adverse effect on waters of the State. Participants in the group represented a broad spectrum of
interests with regard to ground water activities. (See Appendix 2 - Meeting Participants.)
The group met eleven times through the year. The first few meetings provided an
introduction and background information on Maine's water resources and current regulatory
setting. Discussions during the remaining meetings focused on new approaches to groundwater
regulation. A preliminary analysis of watersheds at risk conducted by the Maine Geological
Survey was instrumental in focusing the recommendations of this report.
This report presents the findings and recommendations developed by the work group
which the Council approved at its December 14, 2006 meeting.
1. Watershed approach.
This group endorsed a watershed approach to addressing water issues.
Scarce resources could be focused on watersheds where there is potential for problems rather
than applying a new approach on a statewide basis.
The watershed approach to addressing water issues should be built on a tiered system:
- Tier 1: Conduct full assessment of water supply and demand, including build-out analysis of
community water needs.
- Tier 2: If Tier 1 analysis indicates need, work with parties to develop a water-use
management plan for the watershed.
- Tier 3: If over-subscription of water use remains after Tier 2 analysis, there may be a need
for a binding dispute resolution process to resolve issues.
2. Ground Water Committee
Establish a Ground Water Committee under the Land and Water
Resources Council. The committee would consist of state agency staff with ground water
responsibilities and expertise and would be advisory to the Land and Water Resources Council.
The Committee would have the following responsibilities:
- Review ground water withdrawal activities.
- Coordinate state ground water information.
- Direct appropriate ground water investigations in "watersheds at risk."
- Convene planning groups of stakeholders as needed to address withdrawals in
"watersheds at risk", in significant local aquifers, or in multi-municipal ground water
- Provide assistance to towns.
- Develop and disseminate educational materials on water resources, regulatory regime.
See the next recommendation.
3. Education on water science and current regulatory rigor.
The Ground Water Committee described in Recommendation 2 would be charged with the
- Develop education materials that clearly describe the various regulations governing
ground water withdrawals and how agencies interact in their implementation.
- Disseminate this information via meetings, conferences, internet resources, and other
4. Changes to regulations
- Drilled Well Reporting: Change definition to include all wells for water withdrawal.
- Natural Resource Protection Act: Modifications to NRPA to address non-agricultural
- Bulk Water: The group recommends that the Legislature review the predicate findings to
see if they are relevant.
- Agricultural wells: High-yield agricultural wells would be reviewed by the Agricultural
Water Management Board under a farm plan.
- Public Water Supplies: No changes are recommended to the regulations governing
public water supplies.
- LURC jurisdiction: LURC will review its standards and rules governing water
withdrawal to identify and make changes as needed to:
- clarify the existing
- assure consistency with DEP and DHHS, where applicable, and
- assure that the Commission's statutory authority over groundwater withdrawal is clearly
Funds for aquifer investigations in watersheds at risk will cost $100,000 annually. The Maine
Geological Survey will contribute an additional $120,000 to this effort by redirecting 1.5 FTE
