Watershed Planning Subcommittee

The Watershed Planning Subcommittee (WPS) meets on the last Monday of a month, approximately four times per year. These meetings include an annual joint meeting with  the Environmental Planning Advisory Committee (EPAC) and a meeting with the Arizona Hydrological Society. WPS is governed by EPAC Bylaws and provides input on EPAC’s Annual Top Environmental Issues list, which guides PAG programs and topics presented at Subcommittee meetings. Water quality issues identified in PAG’s 208 Plan drive WPS meeting topics and the EPAC Top Issues list, in order to enhance regional coordination and planning efforts which address the issues.

The Subcommittee discusses pertinent water-related issues and provides advice to EPAC for regional coordination and planning purposes. For example, WPS may work with PAG staff to draft regional Resolutions and WPS members vote on Amendments to the PAG's Section 208 Areawide Water Quality Management Plan. EPAC reports recommendations to be considered by the PAG Regional Council.  Water-related meeting topics include: water quality issues, stormwater management, wastewater treatment and use, groundwater levels and pumping, riparian ecology, green infrastructure and more.

Members include representatives from jurisdictions and various interest groups, including the University of Arizona and water companies. All interested parties are welcome to attend, participate and suggest pertinent presentation topics. Those interested in participating may contact Mead Mier.

Other related committees include the Stormwater Management Working Group, the Statewide Water Quality Management Working Group and 208 Planning Task Forces, which are formed as needed to provide a public comment venue.

PAG 208 Plan Update

The Regional Council of Pima Association of Governments approved the Areawide Water Quality Management Plan (208 Plan) on Jan. 30, 2020.

The 208 Plan will be further reviewed by the Arizona Department of Environmental Quality and the U.S. Environmental Protection Agency for anticipated approval within approximately three months.

2020 Areawide Water Quality Management Plan, including appendices:

As the region's designated planning agency, PAG is required to update the 208 Plan under Section 208 of the federal Clean Water Act. Plan updates reflect changing water quality conditions, results of implementation actions or new requirements to meet water quality management goals and protect priority water bodies.

The draft was developed with coordination among local jurisdictions and stakeholders and includes the following recommendations:

  • Streamlining permit review procedure for a facility to achieve 208 consistency while maintaining meaningful regional coordination points.
  • Providing updates to the water quality issues and programs inventory.
  • Alignment of the Strategic Action Plan with the goals of local programs in the region that may benefit from water quality funding.

Committee feedback, public comments, and PAG responses are documented in the public participation records included in Appendix B.

To read the PAG 208 Plan adopted in 2006 and to view the discussions at meetings during the update process, please visit the 208 page.

Lower Santa Cruz River Basin Study

Through PAG’s public committees, regional stakeholders representing municipal, agricultural, environmental, industrial and tribal water providers, users and others will have an opportunity to weigh in on the Lower Santa Cruz River Basin Study. The Tucson metro area is one of only two regions which were selected by the U.S. Bureau of Reclamation for the three-year climate-model and scenario-planning study, based on strong local water planning efforts already in place to complement the project. Basin Studies are cost-shared, collaborative studies with the goal of identifying where physical water resources are needed to mitigate climate change impacts and improve water reliability for all sectors.
