WHATCOM COUNTY COUNCIL Natural Resources Committee September 14, 2004 Committee Chair Sharon Roy called the meeting to order at 9:30 a.m. in the Council Chambers, 311 Grand Avenue, Bellingham, Washington. Present: Absent: Seth Fleetwood None Laurie Caskey- Schreiber Also Present: Barbara Brenner Dan McShane SPECIAL PRESENTATION 1. PRESENTATION ON A USGS STUDY REGARDING THE MERCURY LEVEL IN LAKE WHATCOM (AB2004 -302) Don Vesper, Environmental Health Services manager, stated the study was done by the United States Geological Survey (USGS) to examine sources, historical and potential, of contamination of lakes in the county, including Lake Whatcom. The report was published about a month ago. Anthony Paulson was the principal investigator on the report. He discussed Mr. Paulson's his background, including work experience and curriculum vitae. Dr. Anthony Paulson, USGS Washington Water Science Chief Environmental Hydrologist and Geochemist, stated this is the final report on their mercury study of Lake Whatcom. The objectives were to examine mercury sedimentation and compare the relative importance of global atmospheric sources with local sources, to examine sources of total mercury in Lake Whatcom, and to examine sources that lead to bio- accumulation of mercury in fish, and to identify any data gaps to study in the future. One approach was to examine existing data. He also collected additional samples in five lakes in Whatcom County. Basin one is small, mostly in the City of Bellingham, and has a maximum depth of 25 meters. Basin two is the same, and also has a depth of 25 to 30 meters. Basin three is the largest, with a 300 -meter depth. The freshwater diversion is in basin three. Regarding sediments, most increases in the mercury concentration occurred before the industrial sources of mercury in Whatcom County opened. The most Natural Resources Committee, 9/14/2004, Page 1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 DISCLAIMER: This document contains the Whatcom County Council or Committee minutes, as approved. However, unless an attested signature page is attached, they are not the final approved minutes. significant increases in mercury in the sediment occurred in the early part of the 19th century, as the beginning of the industrial revolution. Atmospheric transport is the only way mercury from major sources in Whatcom County could enter Lake Whatcom. Those industrial sources are not in the Lake Whatcom watershed. Therefore, mercury can't get into Lake Whatcom from those sources by a water path. Mercury is transported in the atmosphere and falls on Lake Whatcom. Regarding enrichment factors, the maximum enrichment rates range from 2.5 to three, which are on the low end of the range found in the United States. Enrichment factors ranging from three to six have been found in other states known to have mercury problems. The pattern of increases follows the deposition of the industrial revolution in the 1900's. Major volcanic eruptions result in the increase in mercury in ice cores. Mercury concentrations began to increase in the early 1900's. It reached a maximum in the 1980's. The ice core sample in recent years shows significantly less mercury than in the 1980's. The decrease is seen in other areas in the United States and Iceland. Sediment study conclusions suggest a global source. The increases in mercury in Lake Whatcom are not unusual for lakes in the United States. The atmospheric deposition model allowed him to estimate the deposition of mercury from local mercury sources. To apply that model, he needed to know wind patterns. Very little wind comes from the north. The dominant pattern is from the southwest or northeast. They also have to look at timelines of mercury emissions from these local sources to understand the impacts from the sources. The Georgia - Pacific plant was modernized in the mid- 1990's, which resulted in improvements in air pollution control devices. It closed in 2002. Two municipal waste incinerators opened in 1974. They were updated because of new federal Environmental Protection Agency (EPA) regulations. The sewage sludge incinerator operated in 1974 and expanded and modernized in 1993. The deposition from an atmospheric source in Bellingham to basin one should be ten times higher than in basin three because of the predominant wind pattern. Because of the lack of advanced air pollution devices in all those devices should result in peak deposition in the 1960's, with significant decreases afterwards. However, the enrichment of mercury in sediment in basins one and three are similar. In addition, basin one and two show no peaks in the 1960's. The peaks actually occur in the 1990's. There was a very small peak in basin three in the 1060's. Atmospheric deposition from mercury from local sources isn't the cause of higher mercury concentration in fish in basin three. The atmospheric deposition of mercury from local sources does not control the mercury concentrations in the sediment in Lake Terrell and Fazon Lake or in the fish in lakes north of Bellingham. To calculate mercury depositing on the surface of Lake Whatcom due to precipitation, he used data from Seattle as part of the mercury network deposition Natural Resources Committee, 9/14/2004, Page 2 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 DISCLAIMER: This document contains the Whatcom County Council or Committee minutes, as approved.

The State Department of Ecology (DOE) total maximum daily load (TMDL) study measured total mercury concentrations in tributaries of ten watersheds. He combined the mercury concentrations in these tributaries with the flow data information. Anderson Creek receives the diversion from the Nooksack middle fork and contributes about 50 percent of the mercury into Lake Whatcom. However, this high load from Anderson Creek is not a result of Anderson Creek being contaminated with mercury. It is a result of the high flow of water from the Nooksack diversion going into Lake Whatcom. The average mercury concentration in Anderson Creek is lower than in many other tributaries. A secondary result of the TMDL study was to calculate suspended concentrations going into Lake Whatcom. A secondary result of the TMDL study was data on suspended matter concentrations and loads going into Lake Whatcom. Tributaries contribute about 59 percent of the known total mercury sources. Non - atmospheric contributions from regional and global sources is 41 percent. He estimates the input from the City of Bellingham sewage sludge incinerator contributes about .1 percent of the total mercury load. However, he cannot verify that these are the only sources of mercury into Lake Whatcom. In order to be convinced these are the only sources, he has to look at mercury output. They need to know the amount of water and sediment are going in and out. The City of Bellingham has a good handle on the water balance of Lake Whatcom. He tried several methods, but could not get the balance of sediments to be consistent with what he's seeing settle into the bottom of Lake Whatcom. There is a large data gap in sediment sources. Regarding biogeochemical mercury concentrations, the fine grain sediments control transport of mercury throughout lake Whatcom. In contrast to total mercury, methyl mercury in sediments is controlled by total organic carbon content in the sediment. Basin one has the highest organic carbon content and the highest methyl mercury concentration due to the eutrophication process. Methyl mercury concentrations in basin three is low because the organic carbon content is low. Mercury concentrations in the upper water column are low. The concentrations are much lower than the drinking water standard. However, the majority of mercury in the lower water column in basins one and two is methylated, which can lead to bio- accumulation. The conclusion on the biogeochemistry component is that the bio- availability of mercury in Lake Whatcom is directly related to the cycling of organic carbon and organic matter. Regarding suggestions for future areas to study, the mercury transport around Lake Whatcom is controlled by the dynamics of the transport of fine sediments. They need to understand sediment dynamics of Lake Whatcom.

Have a better understanding of the bio- accumulation in fish. Concentrate on the habitat of the fish and where the fishermen catch the fish. Caskey- Schreiber asked about the conclusions regarding the lower water column. In basin one and two, he noted a higher degree of accumulation in the exchange to methyl mercury. She asked what they can expect to happen in that area if it's disturbed. She asked if there are precautions the County should take. Paulson stated the information was taken from 2002 when the bottom water was separated from surface layer due to stratification. This was the worst case scenario. The mercury in the methylated form will be mixed in the water column. Mercury is very reactive to the presence of oxygen. The bond between methyl and mercury will break up in the presence of oxygen, when the water column turns over. Caskey- Schreiber asked if they should take precautions about fishing in those areas during the summer months. Paulson stated fish won't be down there. Most organisms will have gotten out of there. There is potential for transformation into the biological food web. Caskey- Schreiber asked if this situation is similar to other lakes, in terms of stratification. Paulson stated stratification is a normal process in many lakes. He hasn't looked into any other lakes. They are sampling other lakes for information on deposition and wind pattern. He didn't look at the geochemistry of those lakes. Roy stated it sounds as if the mercury is transported by sediment into the lake. Paulson stated the atmospheric transport is the most significant. A small component would be the particles released as part of stack emissions. Most of the transport will occur and is associated with rain. The transport of sediment comes from tributaries where mercury may have fallen. About every five years, one centimeter of sediment has come from the tributaries. Fleetwood asked if there is a public health response that is warranted in excess of what they're already doing in light of this study. Paulson stated they already have the fish warnings. The water concentrations in Whatcom County and most of the tributaries are less than the chronic water quality standards. It is much less than the drinking water standards. Caskey- Schreiber asked if Mr. Paulson noticed an upward trend in the methyl mercury in the lower water column. Paulson stated this analysis was done only once, in 2002. It's very expensive to get this level of sensitivity in testing. The regulatory community is only now beginning to use this sensitive technique. The City of Bellingham began looking at the water concentrations at the gatehouse and Nooksack diversion when they saw these results. They realized the importance of doing mercury analysis correctly. Shortly after this data was available, the City of Bellingham initiated monitoring in the lake, diversion, and gatehouse using this sensitive and expensive technique.

However, unless an attested signature page is attached, they are not the final approved minutes. 1 2 Roy asked if the monitoring is something that they need to continue. 3 Paulson stated it fits in with the eutrophication process that the Health Department 4 is looking at. The bioavailability of mercury depends on the transport and cycling 5 of organic carbon and organic matter. If they want to have a handle on the health 6 of basin one, continue these types of studies. 7 8 Bruce Roll, Water Resources Division Manager, stated they have to look at 9 this in the context of nutrient cycling, and the inputs that stimulate the increases in 10 organic matter. The TMDL is going forward because phosphorus being pushed into 11 the lake will stimulate growth, and organic levels go up. This indicates that as they 12 stimulate environments with low oxygen with additional organic matter, they will 13 see an increase in methyl mercury. Deal with the inputs that stimulate 14 development of methyl mercury. Separate the amount and concentration detected 15 here and the detection in drinking water supplies. This is an issue of 16 bioaccumulation. It shouldn't be construed as a worry or threat to the drinking 17 water. Levels are very low levels, which are a thousand -fold less than drinking 18 water standards. Manage differently as fisheries versus as a drinking water 19 manager. 20 21 (Clerk's Note: End of tape one, side A.) 22 23 Al Hanners, retired geologist, stated he studied mercury in this area without 24 access to core data. He came to the conclusion, based on more regional studies, 25 that the source of mercury in Lake Whatcom was atmospheric. It's the same 26 conclusion as Mr. Paulson's conclusion. He complimented USGS and Mr. Paulson on 27 this study. He also complimented the Council and other entities for hiring Mr. 28 Paulson for this study. 29 30 He asked the relationship of water without oxygen as important to methyl 31 mercury. The organic matter is important. The oxygenated water and the water 32 without oxygen gets mixed due to lake turnover. That might not matter as long as 33 the whole basin isn't lacking oxygen. 34 35 Paulson stated once oxygen is used up, the bacteria are looking for other 36 oxygen donors. First they use oxygen, then they use the nitrate in the water to 37 oxidize organic matter. Last, they go after the sulfate. Bacteria are looking for the 38 oxygen in sulfate to oxidize organic matter. Methyl mercury is a byproduct of 39 bacteria transforming the sulfate into hydrogen sulfide, which uses up the oxygen 40 from sulfate. They usually only find methyl mercury in high concentrations when 41 there is little oxygen. 42 43 Hanners asked the relative significance of the formation of methyl mercury in 44 the various basins in accordance with the amounts of organic matter and oxygen. 45 Paulson stated they haven't looked at it enough to put the whole puzzle together. 46 Natural Resources Committee, 9/14/2004, Page 5 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 DISCLAIMER: This document contains the Whatcom County Council or Committee minutes, as approved. However, unless an attested signature page is attached, they are not the final approved minutes. Hanners stated this question has been raised locally. Paulson stated they have only ten pieces of a 50 -piece puzzle. Hanners asked for a comment on the smelter in Tacoma. That could have contributed mercury here. Paulson stated that would be considered part of the global and regional input. The smelter was shut down around 1980. McShane stated the work is well done. He appreciated the USGS stepping in and getting involved. It goes a long ways toward getting rid of the myths around this issue. Paulson stated this work was based upon existing data from the work of the DOE staff, City of Bellingham, and others. COMMITTEE DISCUSSION AND RECOMMENDATION TO COUNCIL 1. DISCUSSION AND BACKGROUND INFORMATION REGARDING THE JORDAN EXPLORATION COMPANY CONTRACTS ON FUTURE PDR PURCHASES AND PERMITTING OF GAS EXPLORATION PROJECTS (AB2004 -306) Kraig Olason, Senior Planner, stated farms from which the County tried to buy development rights all had gas exploration contracts with Jordan Exploration. These contracts allow for a variety of uses on the properties. Rod Thompson, State Department of Ecology (DOE) hydro - geologist, stated the DOE has had a minimal involvement with oil and gas drilling because it is the jurisdiction of the State Department of Natural Resources (DNR). However, in the permitting process, there are water quality concerns about drilling any oil and gas well, which includes this coal bed methane. In the past during permitting processes, the DOE was involved. In the Revised Code of Washington (RCW) and Washington Administrative Code (WAC) for DNR, there are several requirements that address protection of ground and surface water quality. There has been very little drilling that has actually taken place in the state. Because of that, the DOE has not delegated resources to address drilling. He talked with people at DNR. Every time there is a rise in oil and gas prices, there is a flurry of leasing activity. As prices go down again, the leases expire, and little drilling activity occurs. One example was a complaint about a well being drilled by Jordan Exploration north of Lynden. The Bellingham Office of DOE looked into it. He was contacted about a nearby drinking water well. That process spurred a meeting between local and State agencies to look at the permitting process. They noticed that the DOE needs to follow up on reviewing these applications. A process needs to make sure there is a plan designed where the local county is contacted, and DOE is assured that the drilling process is reviewed for potential hazardous effects to human health. It would look at mud pit concentrations and waste, identify primary parameters of potential contamination, and address these issues through the DNR permit.

However, unless an attested signature page is attached, they are not the final approved minutes. Methane gas is normally a shallow gas found in coal beds. He provided handouts that list the information they will require from any drilling (on file). They look at wells that are 500 to 3,000 feet deep, where the coal is found. When the company produces these wells, a lot of water is produced with the gas. The DOE needs to know what happens to this water. The water must be disposed of properly. Brenner asked if there is a potential for the methane getting into someone's house through their well. Thompson stated there is a potential of getting into the water well, but not necessarily into the house. There is a casing to protect the drinking water aquifers. If they are going to explore and do drilling, the DOE needs to keep track of water quality issues. Caskey- Schreiber asked if sensitive salmon habitat ecosystems would be a component in the review of water discharge. Thompson stated it would. Surface water is one of the largest concerns. The plan has been to contain all surface water that could be contaminated. They may get DNR to require that as part of the permit. They are negotiating the permit right now. The DOE gave the DNR recommendations to improve the DNR's water quality protection during the drilling process. The DNR rewrote its permit, and is at the State Attorney General's Office to see how many of the DOE's recommendations can be included in the permit process legally. They will be able to address the major concerns of control over the mud pit systems and production water. Roy asked where the County fits into the permitting process. Thompson stated the issues will be addressed through the DNR permit. The permit will require the applicant to contact the solid waste staff of the county in which the drilling will occur. The health department will look at the plans also. The DNR will stick to that, and doesn't think it will be an issue. Caskey - Schreiber asked if this site on Pangborn Road is one of the first sites in the state. Thompson stated there was drilling that dated back to World War II. Drilling has been scattered around the state. There hasn't been a commercial production field in Washington. Caskey- Schreiber stated there are many lease agreements on a lot of agricultural land. If they draw the water out and leave it contaminated, it would be devastating to the county. Thompson stated they would have to de -water the wells. That is a concern. Caskey- Schreiber stated something like that could derail the water resource inventory area (WRIA) planning process. Fleetwood asked for clarification on the role of the County Health Department.

However, unless an attested signature page is attached, they are not the final approved minutes. Jeff Hegedus, Environmental Health Supervisor, stated his first experience with regulating gas exploration in Lynden was last year. The Health Department investigated a public complaint about a concern with their water quality based on a drilling operation. Jordon Exploration was drilling in violation of State regulations. The DNR wasn't aware of or able to oversee this operation. The permit issued stated the DOE would oversee their waste management, which wasn't the DOE's role. The operators were to develop their own waste management plan. The DOE deals with the polluting of surface or groundwater. As a result of the complaint and investigation, Jordon properly disposed of all their waste and completed their project. The DOE and DNR met to tighten down their permitting process. The DNR feels it is too thin on resources for site specific oversight and that it doesn't have the proper knowledge yet. A local health department can provide some oversight, but it can't carry the weight of the permitting agency, which is the DNR. Caskey- Schreiber stated she's surprised that this company doesn't know how to implement best management practices in their waste management. She asked if their leases could be considered void. Hegedus stated the DNR did say they had to comply with state regulations. Caskey- Schreiber stated that if the citizen hadn't complained, there would have been a catastrophe, and the County would have to clean it up. Hegedus stated that in this case, the catastrophe was averted. The citizen's well met the drinking water standards. Roy asked if the Department of Agriculture is not willing to go forward with purchases of development rights (PDRs) with these drilling leases. Olason stated that the current landowner contract with Jordan Exploration is quite broad. He wants measures to further limit a freely - granted contract that is from the landowner to the exploration company. Limit what's listed in the contract. He will look at the contract amendment that he's proposing. The contract amendment seems to be okay with Jordon and Natural Resources Conservation Service (NRCS). The amendment is between Jordon and the landowner. He suggested that the County require the landowner get this signed and recorded to amend the landowner's contract with Jordan. Items one through five in the lease amendment address several issues and provide for contact with the County prior to drilling. Fleetwood asked what the USDA didn't like about the contract. Olason stated they didn't like how broad the contracts are. The USDA feels the amendment is adequate. A threat bigger than de- watering is if the operator spreads polluted water on the ground. The County will be in the loop on the parcels for which it owns development rights. It may be something the County will have to take a real strong position on. McShane stated he supports the amendment. He asked if they should look at development standards and zoning in terms of the footprint of these operations Natural Resources Committee, 9/14/2004, Page 8 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 DISCLAIMER: This document contains the Whatcom County Council or Committee minutes, as approved. However, unless an attested signature page is attached, they are not the final approved minutes. beyond the lease parcels. The agricultural zoning is to preserve agriculture. However, this use provides a decent return to the landowners. Olason stated he can look into it. The County is preempted from having land use regulations be overly restrictive of oil exploration or drilling. It depends on how intense the company extracts. If they did it, it would maximize its investment by doing a lot of extraction. One limitation locally is there are a lot of gas lines in the ground. McShane stated there is also a lot of water. Roy asked if the councilmembers object to the amendment. Fleetwood moved to approve the amendment. Motion carried unanimously. Caskey- Schreiber asked if there is anything they need to put in the amendment saying the landowners should not renew the leases when they expire in 2008. Olason stated that if the County has an easement on the property, it would have to be involved in any lease. Caskey- Schreiber stated they have to educate the community about signing these leases.
