Introduction of Members and Guests:

Those in attendance introduced themselves.

 

Discussion Items:

Magnesium Chloride Studies.† Dale Miller informed the Advisory Board that the County has been working with Betsy Miller and Bill Jacobi from Colorado State University on a research project to examine environmental issues associated with magnesium chloride used for dust suppression and road base stabilization on gravel roads.† The studies have concentrated on mountain area roads in Larimer and Grand Counties.† Betsy Miller presented the results of their study using a power point presentation.† The research objectives were to quantify the effects of magnesium chloride use on vegetation, determine the extent of movement into roadside soils and plants, determine the influence of drainage patterns, determine the extend of leaching into streams, and to test various concentrations of magnesium chloride on select species of evergreen trees in a controlled environment.† †The conclusions from each of these objectives are shown in bullet form on this summary table:

The researchers offered a number of suggestions for best management practices for consideration in addressing these impacts.† They include: the use of non-chloride based products along forested roadways or in areas of steep curves or side slopes, reduction in the application rate of magnesium chloride, timing the application to avoid rainfall events, and the application of techniques to reduce the velocity and sedimentation from stormwater flow off of roadways.† Dale Miller noted that this is an ongoing study, and that the County is currently considering ways to address the negative issues associated with magnesium chloride while still addressing the roadbed stabilization and dust suppression needs on mountain gravel roads.† As an interim step, the County has stopped applying magnesium chloride in those areas with steep slopes and sharp curves that tend to create a situation where the most damage was observed.†

 

EAB 2008 Workplan.† Each year the Advisory Board includes a general workplan for the coming year in its annual report.† Dour Ryan prepared a draft workplan based on the 2007 plan and the list of current projects that the EAB is working on.† Members offered some suggested modifications, including the addition of air quality issues under the current environmental topics category.† Mr. Ryan will incorporate those changes as he prepares the annual report.

 

Chairís Comments:

Dale Lockwood discussed the Advisory Boardís project related to the review of environmental impacts of uranium mining.† A draft outline was distributed, and members discussed important topics that should be incorporated into the report.† Members volunteered to research specific topics, add content, and assist in editing of the report.† Much of this preliminary work will be done by email, with a possible committee meeting in January or February.† Based on the request of Commissioner Eubanks that the report be available by mid-February, the plan is to bring the finished report to the February 12 regular meeting for final review and approval by the full Advisory Board.†

 

Updates:

Tom Sneider passed around two articles from the national press relating to the uranium mining in Weld County.

 

Devin Odell asked about the schedule for releasing the draft Environmental Impact Statement for Glade Reservoir (the NISP water project).† Mr. Ryan reported that the latest news available to the County is that the Army Corps of Engineers plans to release the draft for public comment in mid-February.† If that schedule remains, it is anticipated that the EAB would review the draft and provide comments to the County Commissioners in March.

 

Dave Gilkey noted that one of his students at CSU has completed a paper examining the history of how Horsetooth Reservoir came to be listed under a fish consumption advisory for mercury levels.† Several members indicated an interest in reading the paper.† Dr. Gilkey will email the study for distribution.

 

Doug Ryan gave a brief update on another issue related to mercury emissions.† This case involved the Allnutt funeral homeís request to relocate two crematorium units to the Resthaven Memorial Gardens located on Hwy 287 between Fort Collins and Loveland.† This is a land use case being reviewed under the Countyís Land Use Code.† The County Department of Health and Environment reviewed air dispersion modeling related to mercury emissions originating from dental fillings introduced into the cremation process.† The Department concluded that the potential exposures were a concern, and they recommended installing scrubbers on the crematorium stack to remove mercury.† Allnutt indicated that they could not accept such a requirement as a condition of approval.† The Planning Commission voted 7 to 0 to deny the land use request.††† A final hearing before the County Commissioners will be the next step if Allnutt decides to proceed with the application.†

 

EAB Issue Index:

Doug Ryan will update the Issue Index related to the topics discussed at the meeting

 

Summary of BCC Communication Issues:

Doug Ryan will update Commissioner Eubanks on the schedule for January and February, and the EABís timeline for completing the uranium report.

 

Next Meeting Agenda:

The EAB is not planning to meet in January.† The next regular meeting will be held on February 12, 2008.† Agenda items include the uranium mining report, an update on the North I-24 EIS, and election of officers.

 

Adjourn:

The meeting ended at 8:45 pm.†
