Joint Meeting of the UMRBA Water Quality Task Force
and UMRBA Water Quality Executive Committee
Call to Order
The combined meeting of the Water Quality Task Force (WQTF) and Water Quality Executive Committee (WQEC) was called to order by Chuck Corell at
Recognition of Marvin Hora
On behalf of the UMRBA Board, Todd Ambs thanked Marvin Hora for his service as chair of the Water Quality Task Force and presented Hora with a certificate of recognition from the UMRBA Board.
Designated Uses for the
Corell began the discussion with some observations regarding the effort to examine designated uses for the Upper Mississippi River (UMR). He stated that the goal of the effort to is to better manage the UMR as a single resource, adding that designated uses are the place to start addressing this within the water quality standards framework.
Rob Morrison commented that it will be important not only to be able to identify existing differences in approach, but also to understand and explain why the differences exist. Corell concurred, noting that the UMR is not a homogenous resource.
Gaylen Reetz observed that this type of effort would need to develop incrementally, with goals set along the way, and an overall expectation of 5 to 10 years until completion.
Mohsen Dkhili asked if it would be important to understand why the differences exist between current uses before moving forward in attempt to make uses more compatible. Marvin Hora commented that there is currently a good deal of consistency between the States in their assignment of designated uses, but that differences arise in how the protection of these uses is implemented. He noted that all States have a warm water aquatic life use applied to the UMR, but also observed that not all States had a drinking water designated use in place for the UMR.
Report from the WQTF to the WQEC Regarding Designated Uses
Jim Baumman provided a report to the WQEC summarizing the discussions that had been held by WQTF to date regarding designated uses. His report included the following comments:
§ The goal of today’s discussion is for the WQTF to consult with the WQEC regarding the possibilities for addressing designated uses and, if there is agreement, jointly develop a work plan addressing the following project elements:
o Expected level of effort, and
o Pace of activity
§ There is currently some interstate consistency on certain designated uses – such as the assignment of aquatic life uses – but that the categorizations may be outdated and in need of refinement. There is an opportunity to take a more current approach to designated uses on the UMR.
§ There is a potential for subcategories to be used, such as one for submerged aquatic vegetation.
§ More consistent UMR designated uses are a necessary foundation for applying more consistent UMR water quality criteria.
§ Potential benefits of this effort, as identified by the WQTF include:
o Improved communication both between States and with the public.
o Improved consistency between states in regard to: fish consumption advisories, drinking water use assignment, and biocriteria development.
o Better “fit” for a large river ecosystem through the application of aquatic life use subcategories.
§ Possible obstacles facing this effort include:
o Time and resource intensive nature of the project.
o Lack of “political will” among involved agencies to make the project succeed.
Baumann asked Larry Shepard to review the perspectives from U.S. EPA he had previously shared with the WQTF. Shepard provided a brief summary including the following observations:
§ States have the authority to set designated uses for their waterbodies, but these must include “fishable” and “swimmable” uses.
§ Elements of designated use revisions that U.S. EPA would encourage States to address include:
o A shift in focus from sport fishery-based to ecosystem-based aquatic life use protection.
o Explicit protection for fish consumption
o Consistent protection of whole body contact recreation.
o Protection of the drinking water use for the entire UMR.
Bill Franz added that, in general, U.S. EPA would like to see a shared waterbody such as the UMR addressed as a single resource, rather than through independent State-by-State approaches.
Designated Uses Case Studies
Rich Batiuk, Associate Director for Science with the U.S.
EPA Chesapeake Bay Program Office gave, via conference call and presentation
slides, a summary of the process by which habitat-specific designated use
subcategories were developed for
Batiuk first provided an overview of the
In regard to designated uses, Batiuk described the effort to refine designated uses as critical to the Chesapeake Bay Program, as it allowed for a common vision to be developed among the six States for the implementation of the Clean Water Act in the Bay. He noted that before the effort commenced, 90% of the Bay and its associated tidal rivers were listed as impaired (in the 1998 impaired waters list), States’ water quality standards as applied to the Bay were different, and the threat of lawsuits was apparent.
Batiuk stated that the Chesapeake 2000 agreement sought to restore and protect key species (rockfish, oysters, and crabs), critical habitats, and water quality. He further described three steps set out by Chesapeake 2000 as: 1) measure the existing water quality in the Bay, 2) determine what level of pollution reduction is needed to restore the Bay, and 3) identify actions necessary to achieve reductions in pollution levels, with a goal of achieving many of the desired improvements by 2010.
Batiuk said the water quality standards that were applied by the States to the Bay were not only different, but did not appear to be attainable, even under “natural” conditions and that updated science needed to be applied in revisiting use designations for Bay. He added that the process of revising designated uses began by looking at the habitats to be protected in the Bay.
Batiuk described the outcome of the designated use effort as developing “local zoning” for the Bay to protect key species and habitats. He noted that the habitat-specific use categories developed for the Bay were:
1) Migratory fish spawning and nursery use
2) Shallow water bay grass use
3) Open water fish and shellfish use
4) Deep water seasonal fish and shellfish use
5) Deep channel seasonal refuge use
Batiuk added that dissolved oxygen criteria were developed for all of the use categories, except for the shallow water bay grass use, for which a clarity criterion was established. (There is also a chlorophyll a criterion established for the open water use.) He added that some uses/criteria only applied seasonally and noted that a jointly-developed criteria document was also completed for the Bay and its refined designated uses.
Batuik described some of the advantages of the refined designated uses as follows:
§ Improved communication to the public about how the Clean Water Act is tied to the protection of key resources.
§ Adapted uses and criteria to seasonal conditions and species’ needs.
§ Allowed for explicit protection of bay grasses via a clarity criterion.
Batiuk next provided an overview of a “six-State use attainability analysis” that was completed to both demonstrate that previously assigned uses and criteria were not attainable even under “pristine” conditions and that the revised uses and criteria would be protective of the Bay’s aquatic life. He also noted that the habitat-specific aquatic life uses were designed as subcategories of the States’ overall aquatic life use designation, rather than a replacement for this designation.
In addition to the incorporation of the refined uses into State water quality standards, Batiuk noted that the States also developed an agreement on their approach to 303(d) listings for the Bay. He added that a basin-wide approach to permitting was also an outgrowth of this effort.
Rob Morrison asked how the dissolved oxygen (DO) criteria were developed and, in particular, how a level of DO associated with an “anthropogenic-free environment” was identified. Batiuk replied that both research on conditions existing before development and observation of existing healthy ecosystems provided reference points for estimating pre-settlement DO levels.
Morrison asked what the expenses were in carrying out

Corell asked whether the States amended their standards
narrowly for applicability of uses/criteria just to the Bay, or whether changes
to standards were more broadly applicable. Batiuk replied that the changes have

Holly Stoerker asked what initiated work on the project. Batiuk replied that it was the possibility of a basin-wide TMDL, along with a recognition of the inconsistencies between States that spurred action. Additionally, he noted that the States moved forward together, providing “strength in numbers” and that this eventually led to relatively smooth adoption of changes to States’ water quality standards.
Hora asked what the administrative structure was that supported this effort. Batiuk answered that there was a Water Quality Steering Committee composed of water quality administrators from the States who gave direction to a shared staff that was performing this work.
(At this point, the call with Batiuk ended and was followed by a discussion among the WQTF and WQEC of the material presented by Batiuk.)
Stoerker noted that a goal was first identified for the
Corell observed that the holistic approach taken for the
Hora commented that taking this approach on the UMR would essentially mean applying “tiered aquatic life uses” to the River.
Stoerker asked the group how they wanted to proceed, whether they wanted to simply continue coordinating on designated uses or undertake the broader effort to define a unique set of uses for the UMR.
Frevert commented that an effort to examine unique uses would, at minimum, develop a better understanding by State Clean Water Act staff of the resources to be protected on the UMR.
Morrison suggested that there should also be consideration of how recreational uses would be applied to the UMR in a more coordinated fashion.
Corell asked the group where effort should begin, realizing that there are limited resources to implement activities.
Reetz proposed an approach including:
1) Improved communication by the WQEC and WQTF regarding their goals, obstacles, and progress made to date,
2) Continuing coordination of States’ programs, and
3) Development of “tiered aquatic life uses” for the UMR.
Missouri’s Use Designations for the UMR

Art Spratlin commented that the issue is focused around
whether or not the Metropolitan St. Louis Sewer District will be required to

disinfection would still be required if the use was changed to secondary
contact recreation. Morrison indicated
that disinfection would not be required in that case. Spratlin commented that

Morrison observed that it might be possible to consider “tiered recreational uses” that are analogous to “tiered aquatic life uses.”
Franz noted that restoration plans are being developed for the UMR in the area that is the subject of this discussion.
Frevert commented that a complicating factor here is that questions have been raised regarding EPA’s bacterial criteria guidance.
WQTF/WQEC Approach to Designated Uses
Corell commented that the WQTF and WQEC appear to have an endgame in mind – the development of tiered aquatic life uses for the UMR, but that the question is how that goal is to be reached. Baumann concurred, adding that it is important to consider how this effort will be pursued as a priority in relationship to other water quality work efforts.
Reetz suggested that the goal should be defined regardless of resource constraints, and then resources should be identified/leveraged to meet that goal. He noted that it might be possible to identify a contractor to work on tiered aquatic life uses.
Frevert commented that there is inherent value in understanding the river better, regardless of whether uses are adopted into State rules. John Olson commented that investigating tiered aquatic life uses for the UMR is appealing. Matt Short added that LTRMP and EMAP programs have existing resources that can be referenced in such an effort.
Frevert noted that any outcome must be defensible and communicated to the public. Olson suggested that refined use classifications may help target impairment identifications.
Baumann noted that if progress is to be made in this area, it will be important to engage other individuals/institutions who can provide information and experience. He suggested that the first year of any project to address refining designated uses may simply be able to answer the question of whether a full effort is feasible and likely to be successful.
Water Quality Task Force Report to the Water Quality Executive Committee
Baumann next provided a report to the WQEC from WQTF covering those areas other than designated uses that the WQTF has been addressing, including fish consumption advisories (FCAs), sediment-related water quality criteria, assessment/listing consultations, and perfluorochemicals (PFCs).
Fish Consumption Advisories
Baumann reminded the group that one of the main objectives
of the WQTF’s FCA work has been to improve consistency between States’
advisories in order to help improve consistency in States’ impairment listings.
He noted that since the 2005 WQTF report on FCAs, progress had been evidenced
Baumann characterized options for further action as:
§ No action.
§ Facilitating “steps in the right direction”, including:
existing protocols (
o Encouraging and improve data sharing.
o Hosting an annual meeting of UMR FCA experts.
o Working to develop consistent UMR-wide messages regarding fish consumption.
o Addressing emerging issues such as PFCs.
Baumann stated that the WQTF needed feedback from the WQEC on:
Corell commented that it is important to have another area, aside from designated uses, where progress is being made in coordination. He also asked the group what the connection point(s) were between FCAs and water quality standards.
Baumann replied that in
Spratlin asked whether it was possible for WQEC members to approach State health directors in pursuit of a UMR-specific approach to FCAs. Frevert commented that this was not likely to be a priority for State health departments.
Sediment-Related Water Quality Criteria
Dave Hokanson provided a brief summary of the status of the sediment-related water quality criteria project, noting that the final “issue paper” for the project had been completed in February 2007 and had included the following three recommendations for further action:
1) Development of a guidance document for sediment-related water quality criteria on the UMR, focusing first on suspended sediment in the upper portion of the UMR,
2) Drafting of a white paper to more thoroughly investigate issues related to sedimentation, and
3) Completing a research needs list to identify areas where further information is needed to support progress in developing sediment-related water criteria.
Baumann suggested options for further action as including:
§ Preparing a research needs list/research recommendations.
§ Encouraging States to move ahead with impairment listings related to sediment as they see appropriate.
§ Working on sediment criteria in conjunction with the designated use effort.
Interstate Consultation on 305(b) Assessment and 303(d) Listing
Baumann summarized the most recent consultation, held at the previous day’s WQTF meeting, noting that consistency seems to be increasing over time as the result of increased communication, that States are moving toward an integrated reporting approach, and that further progress is likely to be limited by differences in States’ water quality standards.
Hokanson noted that the “map chart” of impairment listings maintained by UMRBA, while valuable in summarizing impairments, does not necessarily capture the progress that has been made in improving consistency between States.
Corell asked whether the utility of the consultations has “peaked” in terms of their ability to encourage consistency and if a new approach was needed to improve the effectiveness of the consultations. Shepard commented that the designated use effort may open up new areas for cooperation. Olson added that continued conversation is likely to lead to continued improvements in consistency. Baumann noted that there are “peaks and valleys” in the consultation process. Shepard observed that differences in timing of assessment/listing between states also make the consultation more challenging.
Hora provided background information on PFCs, including the following:
§ PFCs were used in the production of many substances, including pesticides and Scotchguard.
At one point, up to 80,000 pounds of PFCs were
discharged annually to the Mississippi River in
§ PFCs are virtually indestructible in the environment.
As a result of the presence of PFCs in fish
tissue, consumption advisories have been issued for the Mississippi River (to
Pool 6) and
It is possible that the fish consumption
advisories may lead to associated impairment listings for the Mississippi River
§ Higher concentrations of PFCs have been found in small bluegills, a pattern opposite of that seen for other compounds.
§ MPCA now has a 26-person team working on PFCs.
§ PFCs are likely to be very prevalent in the environment, so that “if you look for it, you will find it”.
§ There is currently limited lab capacity for PFC fish tissue analysis, with only two labs currently doing the analysis. Analyses are also relatively expensive.
Todd Ambs thanked Baumann for the report, encouraging the WQTF to keep working in areas where there have been successes and encouraging all to “tell the story” of the progress being made in interstate cooperation on the UMR. He suggested that materials could be developed for distribution which summarize the efforts and successes of UMRBA’s water quality programs. Good concurred, suggesting the development of a fact sheet noting successes to date.
Travel Reimbursement Policy
Stoerker reviewed the travel reimbursement policy for UMRBA water quality committees, as adopted by the UMRBA Board, which limits reimbursement to those States who have paid their “water quality assessment” in the current or preceding fiscal year.
