Follow-up on Temperature TMDL Presentation: Avis Newell (DEQ) first addressed
comments and questions that had been submitted after last month’s Temperature TMDL
presentation.
Update on Oregon Department of Environmental Quality (DEQ) Toxic Pollutants
Rulemaking: Avis Newell provided the Council with an update on the proposed
rulemaking announcement for toxic pollutants. The DEQ proposes to “revise the water
quality standards regulation to address the human health criteria for toxic pollutants.”
The proposed rule covers 114 different types of toxic pollutants and would change the
estimate for grams of fish consumed by humans from 6.5 grams/day to 175 grams/day. A
Public Comment Hearing will be held on March 7th in Salem; comments on the proposed
changes can be submitted until March 21st at 5:00 p.m.
The Tualatin Phosphorous TMDL – Proposed Allocations: Avis Newell noted that a
Phosphorus TMDL for the Tualatin River basin was first written in 1988 due to water
quality violations. The lower 9 miles of the Tualatin River and the lower reaches of some
tributaries were noted as an area of concern. This low gradient, slow moving portion of
the river was more prone to algal blooms which increased pH and caused a depletion of
dissolved oxygen when the blooms died-off. The TMDL was revised in 2001 and the
target for allowable total phosphorus concentrations for the basin was changed from
0.02–0.07 mg/L (set to control chlorophyll-a concentrations at summer low flow) to
0.04–0.19 mg/L (based on natural background concentrations of phosphorus). As a result
of this revision, the lower river met the target for total phosphorus and the algal blooms
were eliminated. The Phosphorus TMDL is currently being revised to address Clean
Water Services’ proposal to begin discharging during the summer months at the Forest

Grove and Hillsboro treatment plants (summer discharge is currently pumped to the Rock
Creek facility). The 2011 revision of the TMDL will include a bubble allocation for
Clean Water Services (i.e. a combined limit for Forest Grove, Hillsboro, and Rock Creek
facilities of 66 pounds per day) but will keep the same targets for phosphorus and the
same allocations for other existing sources. The bubble allocation will allow for
flexibility in the operations at each plant and protect water quality.
Coordinator Update: April Olbrich noted that the April Council meeting will focus on
committee reports including a discussion of the 2011/2012 work plan for each committee
(to be included in the Council Work Plan). Kate Holleran of Metro will also be giving a
brief presentation on the Chehalem Ridge natural area at the meeting. April also
provided the Council with an update on Measure 76.
TRWC Committee Updates:
 Education and Outreach: The Committee has been working on annual reports,
Council PowerPoint presentations, a hand-out for Clean Water Festival, and an
update of the Council website (summer 2011).
 Restoration and Enhancement: The Committee had a regularly scheduled
monthly meeting and continued on-going discussions from previous meetings.
 Issues Forum: The Committee discussed a number of items including the
following:
o Memo from Jonathan Schlueter in regards to the Temperature TMDL
presentation (February Council Meeting)
o ODF Forest Practices Rules; An independent review committee from the
OSU Institute of Natural Resources (INR) provided input and comments
in regards to current and proposed Forest Practices Rules; the Issues
Forum Committee thanked the INR independent review committee for the
thorough review and noted that TRWC members were asked to review the
findings of the INR committee.
o Climate change in the lower Willamette Basin; Invite authors to an
upcoming Council meeting
