INTRODUCTION The city of Renton is developing a mosquito abatement program for the Panther Creek wetland . In order to assess any effects of this program to wildlife, baseline data is needed. Earlier wildlife surveys in the Panther Creek wetland provided information on fish , birds , and mammals , but no surveys for amphibians and reptiles have been completed. To complete the baseline data, the Renton Parks and Recreation Department requested Shapiro and Associates , Inc. to survey the Panther Creek wetland for reptiles and amphibians . II . STUDY AREA The survey area is located in the city of Renton in King County, WA. and is bordered on the west by Route 167, on the east by the toe of a wooded slope, on the north by a powerline corridor near South 23rd Street, and on the southside by Valley General Hospital . Panther Creek flows through the southern end of the wetland where an approximately ten-acre forested section is present on the alluvial gravels surrounding the creek. The dominant overstory species are cottonwood (Populus trichocarpa) , willow (Salix sp.) , and bigleaf maple (Acer macrophyllum cattered open areas dominated by herbaceous plant species are found thoroughout this forested reach . The remaining wetland area is dominated by thick , monotypic stands of cattail (Typha latifolia) , reed canarygrass (Phalaris arundinacea) , and buttercup (Ranunculus sp.), with scattered willow stands . During August, open water areas were limited to several small (<10 ft square) areas among dense stands of cattails, and in small stream channels of Panther Creek . A transition zone between upland and wetland is present along the toe of the eastside slope. III. METHODS AND MATERIALS Two types of capture methods were used to survey the Panther Creek wetland for amphibians and reptiles , funnel traps and active searches . Funnel traps were used to census salamanders , and day and evening surveys were completed for both amphibians and reptiles . Funnel traps are a passive capture technique used to survey amphibians (Balgooyen, 1977) . Two funnel traps were installed in the study area (Figure 1) . Each trap consisted of two, one foot high , eight foot long plastic net pannels supported by stakes and a one foot deep plastic pot. The pannels were arranged in a funnel pattern, five feet apart at one end leading towards a plastic bucket sunk in the ground. When a salamander encounters one of the drift nets it follows along the net's base and falls into the bucket. The traps were set one evening per week for three weeks and checked after 3 hours , and again the Lfollowing morning. When not in use, the plastic buckets were covered to prevent amphibians and small mammals from falling in. The traps were set at approximately 8:00 PM and closed by 7:30 AM the next day. The funnel traps I were set during the evenings of August 7, August 15, and August 22, 1989. The trap in the southern section of the wetland was placed four feet from `a branch of Panther Creek and the northern trap was located on a small bench area dominated by horsetail and snowberry at the toe of the slope. Vegetation was too thick, and the water table too high in most sections of the wetland to effectively use funnel traps . 1 - -! ♦-----------_ice \ �t 1 // �� � It 74 n \ 1 I 1!

These searches were three to four hours long and a headlamp was employed after sunset. The search was conducted by looking under debris, in vegetation along open water, under stumps , and in other suitable reptile and amphibian habitats. 3-pecies , time, date, and location were recorded for each amphibian and r-ptile capture. Captured animals were released after the data was recorded. Searches were conducted during the same evenings that the funnel traps were set . In addition , an afternoon survey was conducted on August 22. IV. RESULTS The results of the Panther Creek reptile and amphibian survey are displayed in Table 1. No salamanders were captured in the funnel traps ; all animals were captured by hand. A total of two snakes , nine frogs , and one salamander were captured (Figure 2) . On August 7 three Pacific treefrogs (Hyla reggi—lla) were captured among the several branches of Panther Creek, in the souk part of the wetland. The capture locations were characterized by open sections within the forested wetland dominated by herbacceous plant species. One common garter snake (Thamnophis sirtalis) was captured in the northern section of the wetland along the transitional habitat on the toe of the slope. The vegetation here consists of an overstory of cottonwood and big leaf maple, with a thick understory of snowberry (Symphoricarpos albus) and horsetail (Equisetum sp .) . The temperature had been in the mid 80 s during the day with ,tt e cloud cover. During the August 15 survey no amphibians or reptiles were observed. The temperature was in the low 70' s during the day with overcast skies , and it had rained the previous day. Four red-legged frogs (Rana aurora) , one Pacific treefrog, one western terrestrial garter snake (T. ele ans and one Ensatina or Oregon salamander (Ensatina eschscholtzii ore onensis) were captured during the August 22 survey. The red-legged Fogs were found in the southern section of the wetland, in open grass and other herbaceous species between the branches of Panther Creek. The western terrestrial garter snake was located in a blow-down- stump between branches of Panther Creek. The Pacific treefrog and the Oregon salamander were both found in the northern portion of the wetland. The treefrog was found among a thick stand of horsetails and scattered cattails , and the Oregon salamander was found under a tire at the toe of the slope. The day was sunny with temperatures in the high 70' s and there was a heavy rain the previous evening. 3 Table 1 Amphibians and Reptiles Observed in the Panther Creek Wetland Species Number Common Garter Snake 1 Thamnophis sirtalis Western Terrestrai 1 Garter Snake 1 Thamnophis elegans Pacific Treefrog 4 Hyla regilla Red-Legged Frog 4 Rana aurora Oregon Salamander 1 Ensatina eschscholtzii oregonensis . t l - 4 11 11 '1 71� i 1 7Q',I 1 I I 1 yl, �Q11 II ; , 1 111 �`1 1 I t l�----------- 1 r 1 1 � U 11 1110 (1 (jJI/ 11 tl 11 >h 11 111 1�� QII 11 11 1 1 11 111 CIF- Y11 II 11 1 Ilia V11 11 111 1 LLJ =iI it it 1 1 III Q11 I - 11 11 1 �I 21I 1 1 I 23RD ST f 11 1 1 rr 1/ 11 11 L1,r r/ I' ii 1 off II 1 I 11 1 11 1 11 II 1 1 II 11 m17 1, It -- -- -----------' `------------------ I a'�== ---- OI 1 11 11 1 I I I it II 11 1 1� 1 11 II I cd II 11 1 Jl�i I 11 t 1 ' rll to ,1 Q 1i 1 1 I I 01, I 11 V W I I }I 1 11 Z �i J it I 1� O Wit Jli 1 I 1t > ,1 Qtl I t\ ui 1 I � 11 1 ji I I 1 1 Q11 ,1 11 7 Oil I 36T7j ST "(S.33TTH ST 1 1 1 FIGURE 2 RED LEGGED FROG • WESTERN TERRESTRIAL GARTER SNAKE REPTILE AND AMPHIBIAN PACIFIC TREE FROG ■ ORES GCN SALAMANDER CAPTURE LOCATIONS G COMMON GARTER SNAKE ® WETLAND AREA SI-{APIRO& PANTHER CREEK REPTILE AND AMPHIBIAN SURVEY A-Q,9=kTES�1 `'-xY V. DISCUSSION The two species of frogs , two species of snakes , and one speces of salamander found in the Panther Creek wetland are common to the region. The single western terrestrial garter snake captured is a less than common occurrence in the Puget Sound area, but not unusual . The species is known to inhabit a variety of habitats including wetlands and moist woods . The common garter snake found in the northern portion of the site represents the most common Puget Sound region snake. Both snakes were captured on days that were warm with little cloud cover. Reptiles are most evident on warm days , and more diurnal surveys would probably reveal other individuals of these or other common snake species . The mix of upland and wetland habitat in the study area provides good habitats for snakes. Pacific treefrogs , found throughout the site, are common in a variety of habitats throughout Puget Sound. This species breeds during spring and probably uses seasonal standing water at the site. Pacific treefrogs are commonly found in dense ground vegetation near water. The lack of standing water areas during the summer could limit the Pacific treefrog population in the Panther Creek wetland. A survey competed during the wetter spring season, when the species is more evident, would probably reveal larger numbers of treefrogs at the site. During the summer, Pacific treefrogs may retreat to secluded moist areas of the site. Red-legged frogs are most commonly found in lowlands and foothills near water. They tend to disperse from secluded moist areas after rains (Stebbins, 1985) , and this is probably why the species was not found until the last survey, which followed a heavy rain. The breeding season lasts only two weeks during early spring after which the species can be found in damp woods . Larger numbers of frogs would be encountered during a breeding season survey. The single Ensatina, or Oregon salamander observed at the site is the most common salamander in the region. The Oregon salamander is a subspecies of Ensatina, a species that ranges from southern California to British Columbia. The Oregon salamander is the only Ensatina subspecies present in Washington. This salamander is commonly found under logs , bark, rocks , and other forest floor debris . The species retreats to moister areas underground during dry spells , and was observed at the site the day following a heavy rain. A lack of surface rocks or other suitable ground cover may limit the number of Oregon salamanders at this site. Because salamanders restrict their movements during the dry summer months the funnel traps were not effective in capturing these animals. Salamanders travel more frequently during the spring and are more susceptible to capture by funnel traps . I 6 VI. SUMMARY The reptile and amphibians captured at the Panther Creek wetland are species common to the Puget Sound region. No state or federally listed threatened or endangered species were obsered during the survey period. The amphibian population may be limited by the lack of standing water at the site during the -summer. The monotypic stands of reed canarygrass, buttercup, and cattails do not provide diverse .habitats for reptiles and amphibians. The majority of reptile and amphibians were observed in the forested wetland at the southern end of the study area, which has a variety of plant communities present. A survey conducted during the wetter spring season, when amphimbians are breeding, would probably reveal higher numbers of amphibians than observed during the August survey. The lack of rocks and other forest floor debris may also limit the salamander populations at the site. 1 7 VII. LITERATURE CITED Balgooyen, T. G. 1977. Collecting methods for amphibians and reptiles.

The Department of Ecology permit review process for the 1989 treatment program specifically stated that an EIS would be required of the City in 1990 in order to treat the wetlands. (See attached letter) I also spoke to Don Erickson, Zoning Administrator and he said that is not the Department of Ecology's call. That would be a determination made by the City's environmental staff. It is my intent to contact Mr. Anderson, DOE, to ask for a clarification, but in the meantime, I think we should proceed as if we need the EIS.

The inventory will consist of three sampling efforts during a three-week period. As we discussed, mid-summer may not be the most suitable time period to inventory these animals, but it is necessary in light of your project schedule. For this inventory, we have proposed two different sampling techniques. First, we will establish funnel traps at three different sites within the wetland, and monitor them for an 18-hour period, approximately once every 4-6 hours. Second, we will conduct night searches to locate and inventory the animals. As the attached budget indicates, we estimate the work will cost approximately $5,300. We are prepared to initiate the inventory as soon as we receive notice to proceed. Mr. Jim Keany will serve as project manager for this investigation. Should you have any questions, please feel free to call either Jim or me. We look forward to the opportunity of working with you on this study.

Particular attention was directed to the Hearing Examiner's report of May 31, 1989, which mandated an inventory of fauna existing in the project area and what would be required to carry it out. The Environmental Review Committee agreed that an existing fauna inventory provided by R.W. Beck and Associates/The Coot Company, in May, 1989, in conjunction with another municipal project, would suffice to meet the Hearing Examiner's requirement for a present count of mammals. However, a sample inventory of reptiles/amphibians will need to be provided to supplement the inventory of mammals. This inventory should be provided by a qualified, independent professional biologic services, such as those provided by R.W. Beck, in advance of the implementation of the mosquito abatement program. (Note: In the ERC's opinion, Mr. Whitworth should not conduct this study, since he will be providing the abatement service. A study performed by him could be perceived as a potential conflict of interest.) Such an inventory is estimated to cost between $1500.00 and $3,000.00. I will be pleased to work with you to develop a specific plan for defining the inventory parameters, establishing a consultant selection method, and reimbursing the consultant for this inventory, if you believe it would help. The above-described approach for carrying out a fauna census, as required by the Hearing Examiner, is an ERC interpretation. City Ordinance prescribes that such an administrative may be appealed, in writing, to the City of Renton Hearing Examiner within fourteen (14) days of this decision, or before 5:00 p.m. on July 19, 1989. An appeal must be accompanied by a $75.00 fee. This letter is being sent to all parties of record. 200 Mill Avenue South - Renton, Washington 98055 - (206)235-2550 Facsimile (206) 235-2513 �i CITY OF RENTON PARKS and RECREATION Earl Clymer, Mayor John E.

As you know, the Hearing Examiner placed an additional condition to the ERC Mitigated Determination of Non-Significance (see attached) . The ERC Committee will be meeting on Wednesday, June 28, 1989 to determine the intent of Mr. Kaufman's condition. Depending on the findings by the ERC Committee, the census may be a base line census that our consultant can do in a short timeframe. If the finding is a complete census, then the City of Renton will be faced with hiring a firm that is capable of providing such a census which includes the seasons (one year in length) . I have received some preliminary estimates that could range anywhere from $50,000 to $100,000 to complete. Once the ERC Committee meets on Wednesday, then an action plan can be implemented.

I am sure there are standard methodologies employed to take a census of wildlife in a given area and to assure that seasonal differences are accounted for. This office would find the choice of one of those proven methodologies, or equivalent, acceptable as long as such a system included a census of frogs, toads and other amphibians as well as reptiles since these species provide the higher orders with a source of food. Finally, further correspondence regarding compliance with the decision should be directed to the ERC as that agency is charged with primary authority over assuring compliance with SEPA.

The Committee, on February 22, 1989, decided that your project may be issued a Determination of Non- Significance-:Mitigated with the following conditions: 1. That, in order to ensure viable, safe habitation/use of properties in the area of the Panther Creek Wetland, the applicant, for 1989 and 1990 only, utilize the products Altosid and Scourge for mosquito abatement, as instructed/permitted by the Department of Ecology and the King County Health Department. 2. That, in order to ensure the necessity/efficacy of the 1989 and 1990 abatement program, the applicant shall develop and adhere to a plan by which a licensed entomologist will undertake monitoring and testing of traps at regular intervals to: a) provide a census; b) recommend an application plan, recognizing that more than one application may be necessary to achieve vector control; and c) monitor the application process to ensure that product application is scheduled at times of the day and in weather conditions which maximize the effectiveness of abatement control and minimize impact upon the human/natural environment. 3. That, in order to preserve the natural environment of Panther Creek Wetlands and Springbrook Creek, during the 1989 and 1990 abatement program, the applicant shall: a) consult with the Department of Wildlife; b) invite comment from the Department of Fisheries. These communications shall take place in advance of each product application during 1989 and 1990 to establish the continuing appropriateness of the proposed systems/products to be used and the application schedule in the event that there are changes in the existing habitat which warrant such approval. 200 Mill Avenue South - Renton, Washington 98055 - (206)235-2550 Mosquito Abatement • Sam Chastain, Director March 1, 1989 Page 2 4. That, in order to ensure public health and safety, the applicant shall: a) provide written information which fully describes the abatement program and schedule to all individual homeowners within the proposed project area along Talbot Road; b) provide written information which fully describes the abatement program and schedule to be published in a local newspaper and posted at regular intervals in the vicinity of the project area; and c) provide notification for/conduct a public meeting to inform interested parties about the proposed abatement project. All notifications should include the name and telephone number of a City representative who can,provide further information about the program to interested parties. The City will not conduct mosquito abatement activities on private property without permission of the property owner. Note: Staff recommend that the above-described information programs be implemented prior to the completion of the comment period for the environmental determination. 5. That, in order to protect the human environment and the natural environment: a) the applicant shall reconfirm the suitability of the proposed (Altosid, Scourge) chemical system on an annual basis, over the life (1989-1993) of this project; and b) the applicant shall submit a new application if new chemical systems or products (other than Altosid or Scourge) are selected by the City/suggested by DOE during the life of the project (1989-1993). Note: Unless the Panther Creek Wetlands Habitat is to be developed within the next two years with a wildlife habitat which will provide biological control of mosquitoes, the Public Works and Parks Departments should work together to provide, prior to the end of calendar year 1991, a comparative analysis which explores options for mosquito abatement through biological control systems, natural selection systems, water manipulation, mechanical control and the proposed chemical control system, including a description of the components of those systems, anticipated positive and negative impacts of each system (e.g. feasibility, efficacy, efficiency, safety), and required mitigation measures. Because the Environmental Review Committee imposed specific mitigation measures rather than issue a Determination of Significance, there is a required fifteen (15) day comment period during which comments are solicited from various agencies, jurisdictions or individuals who may have an interest in the Committee's decision. The comment period will end March 14, 1989. Following the end of the comment period, the City will finalize it's Determination unless comments received require a reevaluation. Following the finalization of the Determination, there is a required fourteen (14) day appeal period. In addition, by the end of the comment period, we should be able to establish a tentative public hearing date before the Hearing Examiner, should a public hearing be necessary.

ISSUES: 1. BACKGROUND The Panther Creek Wetlands provide a breeding ground for several species of mosquito. The City considers mosquito control to be necessary when the mosquito population becomes sufficiently large to impact upon health and safety of nearby residents and passers-by using' local roadways as well as major arterials, and to interfere with recreational use of the area. Factors taken into account in making a determination that it is necessary to begin vector control and the selection of systems for doing so include: a) a census which determines that the number and type of mosquitos present pose a health hazard; b) citizen complaints; and c) the availability of approved chemical systems/products to control the mosquito population without significantly endangering human safety, or the natural environment; and d) the efficacy/feasibility of alternatives for abatement -- such as allowing natural control (i.e. when mosquito population becomes too great to be supported by the existing environment the population will abate) ; water manipulation (filling wetlands, cutting back wetland grasses, changing water flow) ; mechanical controls (e.g. traps, "bug" lights) ; or biological controls (introduction of reptiles, gambusia [mosquito fish] , native minnows, bats, and birds to eat the mosquitoes) . The growth of the mosquito population is tied to weather patterns -- moist weather conditions encourage breeding. Because of the weather-related connection, there is no regular interval for vector control activities. The last such project took place at Panther Creek approximately four (4) years ago. No major, coordinated activities have been undertaken on adjacent private properties (where mosquitoes breed in standing water) , nor are such activities planned by property owners either privately or under City aegis. Plans to enter into a mosquito abatement project at this time have been/will be coordinated with and approved by the EPA, the Department of Ecology, the Health Department, the Department of Transportation, the Department of Fisheries and the Department of Game/Wildlife. (See records for more detailed information. ) Technical Advisory Committee Staff Report City of Renton - Parks Department - Mosquito Abatement Page 3 February 15, 1989 2 . ENVIRONMENTAL ELEMENTS a. Whether sufficient evidence exists to support the need to enter into a mosquito abatement program at this time? A series of surveys of the Panther Creek Wetlands by a licensed entomologist employed by the City has indicated that the mosquito population is sufficiently large to cause concern for the welfare of nearby residents and persons engaged in passive recreational activities in the area. Additionally, City offices have logged communications from persons living nearby to Panther Creek Wetlands expressing concern about the density of the mosquito population and requesting abatement services; one resident has objected to City plans for mosquito abatement because he believes that the proposed products would hinder the well- being of birds and animals which he would like to introduce into the wetland area adjacent to his home. b. Whether the type of control system and abatement schedule has been determined to be safe to human and wildlife population and adequate to control the mosquito population? The City has selected two target specific pesticides, Altosid and Scourge. Altosid is an insecticide in a briquet form which controls larvae; it will be placed in the water with a power spreader/backpack blower. It remains viable for a period of approximately thirty (30) days. Scourge (a mixture of SBP-1382 and Piperonyl butoxide) , a low toxicity mosquito adulticide, will be applied by ground spreader into the brush immediately surrounding the wetland. It is a contact control product which remains viable for approximately three to four days. These products are registered with the EPA and both are approved by the Department of Ecology, the Department of Transportation and by the King County Health Department. Altosid and Scourge are reported to be safe for use in areas frequented by people; these products are also reported to be suitable for use within the local ecosystem. The Department of Fisheries has indicated that no Fisheries permits are necessary for this project because there are no fish in the project area. • Technical Advisory Committee Staff Report City of Renton - Parks Department - Mosquito Abatement Page 4 February 15, 1989 Representatives of the Department of Fisheries and the Department of Game/Wildlife suggest that while the proposed chemical control system may be acceptable, abatement through natural selection (reduction of the population when it becomes too great to be supported by the existing environment) , mechanical control, or the introduction of biological controls is preferred over chemical control, where it is feasible to do so. Note is made of several considerations reviewed in exploration of alternatives: 1) the natural selection system which occurs in years in which no chemical control system is used, has not generally met the expectations/desires of local residents for management of the mosquito population; 2) habitat/water manipulation becomes effective over time, as the new system becomes established; immediate significant reduction of mosquito populations should not be expected; 3) the introduction of habitat/water manipulation and/or the introduction of a sufficient range and number of species of fauna to obtain biological control of mosquitoes has the potential for creating other imbalances in the ecological system; and 4) there is limited information concerning the viability of mechanical control systems over large areas, such as the Panther Creek Wetlands. Representatives of the Departments of Game/Wildlife and of the University of Washington Zoology Department, representatives of Washington State University Agricultural Department (Insect Physiology) and a certified local entomologist specializing in toxicology reported that the pesticides (Altosid, Scourge) selected by the City of Renton are target specific; there is no data indicating that the proposed chemical control system has a significant impact on on-site or vicinity (e.g. Springbrook Creek) ecosystems either in the short term or over time. Staff believe that for the present, the proposed chemical control system is determined to be the most effective, safe, efficient method for short-term mosquito control in the Panther Creek Wetlands. Impacts to fish in nearby Springbrook Creek are not expected to be significant because the proposed insecticides are target-specific and because any product residue would be dissipated/diluted well before the water from the wetlands merges with the stream. . -.. -.4T•, •'fir Technical Advisory Committee Staff Report City of Renton - Parks Department - Mosquito Abatement Page 5 February 15, 1989 Therefore, in order to protect the human and natural environments, staff recommend that for 1989, the proposed abatement program be permitted under a system/application schedule which provides for monitoring and control as appropriate, by a licensed entomologist, by the Department of Wildlife, by the Department of Fisheries, by the Department of Ecology, and by the Department of Health. Additionally, local residents and visitors should be provided with complete information about the vector control system and notification of application schedules on a continuing basis. (Specific description of required monitoring, control and information plans is presented below under Section C - Recommendations) Note: The Panther Creek Wetlands Project Study reports upon opportunities to develop a quality wildlife habitat in the area, including the provision of fish channels that would connect Panther Creek to the P-9 Channel. It will likely become necessary (as the City proceeds with its objectives for creating recreational opportunities and developing a wetland/wildlife habitat over) for the Parks Department to employ other than chemical mosquito control measures as outlined in the Panther Creek Report (e.g. water manipulation; the introduction of fish, bats or swallows that eat mosquito larvae) so as not to adversely impact this area. Staff note that the Public Works Department, SCS, the Department of Fisheries and other agencies are now working cooperatively to create a plan for water/habitat modification to develop an ecosystem in the Panther Creek Wetlands Area; it is anticipated that the planning and implementation of this project will take approximately two years. Staff recommend that if the Panther Creek Wetlands Habitat Development Project is not to be implemented within the next two years, the proponent should be required to begin to explore options for mosquito abatement through natural selection, water manipulation, mechanical control and biological control and provide a report comparing the impacts mitigation measures required for these systems, as well as the chemical control system. Results of that comparative analysis recommended by staff should be submitted by the proponent to the City by the end of calendar year 1989. At that time the Environmental Review Committee will review all options for mosquito Technical Advisory Committee Staff Report City of Renton - Parks Department - Mosquito Abatement Page 6 February 15, 1989 abatement and make a determination concerning system(s) to be employed for the years 1990 through 1993 . At the time of that determination, if the chemical control system is permitted, conditions will be established which will require that the applicant reconfirm the suitability of the proposed insecticides annually, over the life (1990-1993) of this project. Staff recommend that if chemical control is permitted, and if new products (other than Altosid or Scourge) are selected by the City/suggested by DOE during this period, a new project application should be required. Note: Staff inquired as to whether recent developments upland of the Panther Creek Wetlands Area would be likely to, in turn, impact the hydrology of those wetlands, and, whether, if changes in hydrology have taken place, these changes have been considered in the selection of an abatement plan. This inquiry was presented to the Public Works Department and staff was informed that there have been no significant changes in area hydrology as a result of recent neighborhood developments. C. RECOMMENDATIONS: Staff recommend that the ERC issue a Determination of Non-Significance - Mitigated, with the following conditions: 1. That, in order to ensure viable, safe habitation/use of properties in the area of the Panther Creek Wetland, the applicant, for 1989 only, utilize the products Altosid and Scourge for mosquito abatement, as instructed/permitted by the Department of Ecology, and the King County Health Department. 2 . That, in order to ensure the necessity/efficacy of the 1989 abatement program, the applicant shall develop and adhere to a plan by which a licensed entomologist will undertake monitoring and testing of traps at regular intervals to: a) provide a census; 2) recommend an application plan, recognizing that more than one application may be necessary to achieve vector control; and 3) monitor the application process to ensure that product application is scheduled at times of the day and in weather conditions which maximize the effectiveness of abatement control and minimize impact upon the human/natural environment. . 3 . That, in order to preserve the natural environment of Panther Creek Wetlands and Springbrook Creek, during the 1989 abatement program, the applicant shall: a) consult with the Department of Wildlife; b) invite comment from the Department of Fisheries. These communications shall ` Technical Advisory Committee Staff Report City of Renton - Parks Department - Mosquito Abatement Page 7 February 15, 1989 take place in ,advance of each product application during this year to establish the continuing appropriateness of the proposed systems/products to be used and the application schedule in the event that there are changes in the existing habitat which warrant such approval. 4 . That, in order to ensure public health and safety, the applicant shall: a) provide written information which fully describes the abatement program and schedule to all individual homeowners within the proposed project area/for a distance 500 feet of the boundaries of that area; b) provide written information which fully describes the abatement program and schedule to be posted at regular intervals in the vicinity of the project area; and c) provide notification for/conduct a public meeting to inform interested parties about the proposed abatement project. All notifications should include the name and telephone number of a City representative who can provide further information about the program to interested parties. Note: Staff recommend that the above- described information programs be implemented prior to the completion of the comment period for the environmental determination. 5. That, unless the Panther Creek Wetlands Habitat is to be developed within the next two years with a wildlife habitat which will provide biological control of mosquitoes, the applicant shall provide, prior to the end of calendar year 1969 , a comparative analysis which explores options for mosquito abatement through biological control systems, natural selection systems, water manipulation, mechanical control and the proposed chemical control system, including a description of the components of those systems, anticipated positive and negative impacts of each system (e.g. feasibility, efficacy, efficiency, safety) , and required mitigation measures. City staff and the Environmental Review Committee will review this information, in order to then select a preferred system and issue a Determination. 6. That, in order to protect the human environment and the natural environment: a) the applicant shall reconfirm the suitability of the proposed (Altosid, Scourge) chemical system on an annual basis, over the life (1989-1993) of this project; and b) the applicant shall submit a new application if new chemical "Technical Advisory Committee Staff Report City of Renton - Parks Department - Mosquito Abatement Page 8 February 15, 1989 systems or products (other than Altosid or Scourge) are selected by the City/suggested by DOE during the life of the project (1989-1993) . D. COMMENTS OF REVIEWING DEPARTMENTS: Various City departments have reviewed and commented upon the project. These comments are as follows: Police Department: Land Use: No impact Fire Prevention Bureau: Land Use: Probable minor impact - public services. Design Engineering: Land Use: Probable minor impacts - earth, air, water, plants, animals. More information necessary - water and animals. Wetlands tributary to Springbrook Creek. Impact on fish and wildlife unknown. Traffic Engineering: Land Use: Probable minor impacts - all elements except animals, environmental health. More information necessary for animals and environmental health. Utility Engineering: Land Use: Probable minor impact - utilities. Panther Creek Wetlands not in APA. Storm Water Drainage: Land Use: No comments received. Parks and Recreation: Land Use: No negative impacts on recreation. Building Division: Land Use: Probable minor impact - housing. Current Planning Division: Land Use: 1) recommend DNS. 2) does any special safety precautions need to be implemented for the abutting homes along the Panther Creek Wetlands? Long Range Planning: Land Use: Probable minor impacts - housing, light & glare, historic & cultural preservation, transportation, public services, and utilities. More information necessary - water and environmental health. Have these products and application processes been recommended and approved by the DOE? Drainage from the Talbot Hill area has been altered and may have a significant impact on the hydrology of the Panther Creek Wetlands. Have these new drainage patterns been studied and have been considered in the selection of an appropriate mosquito abatement product and technique? The mosquito abatement program is a controversial public issue. Due to citizen concerns about public and environmental health and safety, the Long Range Planning Dept. feels that this program should go through a broader public review process. •4A' Cyr CITY OF R I NTON I1 1 l 1 ► : U « ) BUILDING & ZONING DEPAIi 1 ML-N 1• _. i1v,Nrt`c'r�' MASTER APPLICATION IMII.

RECOMMENDATIONS : Issue a Determination of Non- Significance-Mitigated with the following conditions: 1. That, in order to ensure viable, safe habitation/use of properties in the area of the Panther Creek Wetland, the applicant, for 1989 and 1990 only, utilize the products Altosid and Scourge for mosquito abatement, as instructed/permitted by the Department of Ecology and the King County Health Department. 2 . That, in order to ensure the necessity/efficacy of the 1989 and 1990 abatement program, the applicant shall develop and adhere to a plan by which a licensed entomologist will undertake monitoring and testing of traps at regular intervals to: a) provide a census; b) recommend an application plan, recognizing that more than one application may be necessary to achieve vector control; and c) monitor the application process to ensure that product application is scheduled at times of the day and in weather conditions which maximize the effectiveness of abatement control and minimize impact upon the human/natural environment. 3 . That, in order to preserve the natural environment of Panther Creek Wetlands and Springbrook Creek, during the 1989 and 1990 abatement- program, the applicant Kali : a) consult with the Department of Wildlife; b) invite comment from the Department of Fisheries. These communications shall take place in advance of each product application during 1989 and 1990 to establish the continuing appropriateness of the proposed systems/products to be used and the application schedule in the event that there are changes in the existing habitat which warrant such approval. Determination of Non-Significance Mc quico Abatement Page 2 4 . That, in order to ensure public health and safety, the applicant shall : a) provide written information which fully describes the abatement program and schedule to all individual homeowners within the proposed project area along Talbot Road; b) provide written information which fully describes the abatement program and schedule to be published in a local newspaper and posted at regular intervals in the vicinity of the project area; and c) provide notification for/conduct a public meeting to inform interested parties about the proposed abatement project. All notifications should include the name and telephone number of a City representative who can provide further information about the program to interested parties. The City will not conduct mosquito abatement activities on private property without permission of the property owner. Note: Staff recommend that the above-described information programs be implemented prior to the completion of the comment period for the environmental determination. 5. That, in order to protect the human environment and the natural environment: a) the applicant shall reconfirm the suitability of the proposed (Altosid, Scourge) chemical system on an annual basis, over the life (1989-1993) of this project; and b) the applicant shall submit a new application if new chemical systems or products (other than Altosid or Scourge) are selected by the City/suggested by DOE during the life of the project (1989-1993) . Note: Unless the Panther Creek Wetlands Habitat is to be developed within the next two years with a wildlife habitat which will provide biological control of mosquitoes, the Public Works and Parks Departments should work together to provide, prior to the end of calendar year 1991, a comparative analysis which explores options for mosquito abatement through biological control systems, natural selection systems, water manipulation, mechanical control and the proposed chemical control system, including a description of the components of those systems, anticipated positive and negative impacts of each system (e.g. feasibility, efficacy, efficiency, safety) , and required mitigation measures. City staff and the Environmental Review Committee will then review this information, in order to then select a preferred system and issue a Determination. mmdoc �i - CITY OF RENTON PARKS and RECREATION�7 Earl Clymer, Mayor John E. Webley, Director M E M O R A N D U M DATE: July 6, 1988 TO: Ron Nelson, Building & Zoning Director FROM: Sam Chastian, Park Superintendent SUBJECT: Mosquito Abatement - Panther Creek Wetlands ELF-036-88 Since filing the Environmental Checklist on May 3, 1988, Mr. Terry Whitworth, Entomologist Consultant, is recommending the use of an insecticide called Altosid briquets in place of the Bacillus thuringiensis. After researching additional information and reviewing test cases of Bacillus thuringiensis, it was found to be ineffective when treating this particular species of mosquitos found in the Panther Creek Wetlands (Coquillettidia perturbans) . Mr. Whitworth recommends the insecticide Altosid which is EPA registered #20954-13-50809 and is a targeted pesticide which released effective levels of the insecticide over a period of 30 days, and two treatments should be sufficient to control the mosquitos if applied in a timely manner. It is important that we proceed as quickly as possible with the treatment only after the Committee has a chance to review the new material. Mr. Whitworth has been in direct contract with Mr. Andy McMillian of the Department of Ecol- ogy at the regional office in Olympia (459-6774) . Please review the attached label for the product Altosid in which it gives a good description of the pesticide. If your committee concurs with this recommendation, I will forward the necessary data to the appropriate state agencies ammending the Environmental Checklist ELF-036-88 submitted May 3, 1988. Thank you in advance for an expedient decision.

Renton, Wa. 98055 Dear Sam, I have talked extensively with the Department of Ecology about h control problem at the Panther Creek Marsh. My primary contactshave sbeen o Andy McMillan at the regional office in Olympia (459-6774) and Norm Peck of the Redmond office (867-7047) . The department has taken the position that they are going to begin closely scruitinizing all proposals to apply pesticides to water. They seeped inclined to reject any proposals involving applications of broad spectrum, residual chemicals. They first said they were worried about affects on fish and waterfowl. I explained that this marsh had no fish and few waterfowl, and the Washington Game Department had indicated they were not concrened about the use of Dursban 2G. They then said they were worried about the affects of Dursban 2G on non-target insects and other aquatic fauna such as dragonflies or freshwater shrimp. I noted that mosquito populations recover very well each year from previous treatments and it would seem these other organisms would also. They said they would be inclined to approve only target specific pesticides ("biologicals") like Bacillus thuringiensis for mosquito control. I pointed out that biological chemicals have some major disadvantages. They require numerous applications, are usually more costly, and require much more monitoring, making any control program much more expensive overall. They were not concrened about cost and suggested mosquitoes were just a nuisance anyway. I noted that this marsh has produced serious mosquito problems on Renton city and private property above the marsh. I also noted Possible problems with mosquito borne diseases if these pests are not controlled. They said they would require an "Environmental Impact Statement" if we wanted to apply any residual pesticides. Even then they would most likely reject an application to use Dursban 2G. It would probably take a mosquito borne epidemic to get them to change their position on this. am Chastain (2) August 26, 1987 I then contacted Lynden Baum (753-5965) , vector specialist for the State Health Department in Olympia. Lynden consults with mosquito abatement districts throughout the state and is an excellent source of information on currect trends and technology in mosquito control. Lynden reviewed the literature he had on Coquillettidia perturbans and he discovered several recent studies on this species. I have copied the most recent journal article and included it with my letter. Researchers in Saint Paul, Minn. had good success controlling Coquillettidia with a product called Altosid, manufactured by Zoecon Chemical. This product contains methoprene, a hormone mimic that prevents mosquitoes from reaching the adult stage. I talked directly with Darold Batzer who did most of the research on this project. He is now at Berkely working on a Ph.D. They used long-lasting briquets, applied on the ice just before spring thaw and got excellent results. Unfortunately these long-term briquets were experimental and are not commercially available. The only briquets available lasts 30 days. It would probably take at least two applications of this product to control the mosquitoes at the Panther Creek site. If all 50 acres had to be treated, it could cost up to $9000. per application for chemical alone, plus labor. I contacted the Department of Ecology again to discuss their attitude about Altosid. They were unhappy because it might affect some other insects. However, Zoecon has extensive data that indicates it would only affect very similar species such as midges. I believe they could be convinced to allow the use of this product. During this research I gathered many other facts which may be of interest to you, but this highlights the major points. Call me if you need further information. Sincerely, 4! t Terry Whitworth, Ph.D. Entomologist Enclosure WHITWORTH PEST CONTROL INC. 3707 - 96th STREET E. TACOMA, WASHINGTON 98446 (206) 535-1818 23 June 1988 ' Sam Chastain Park Superintendent 200 Mill Ave. South Renton, Wa. 98055 Dear Sam, I inspected the Panther Creek Marsh yesterday (6/12/88) and water levels are quite high for this late in the year. I suspect you will have mosquito problems throughout the summer, unless control measures are taken. Based on my research last fall I would recommend we use Altosid Briquets for mosquito control . This product contains methoprene , a chemical which prevents emergence of adult mosquitoes . Extensive research on this material shows it is especially effective against Coquillettidia perturbans , the primary mosquito in the Renton area. This product will not effect pupae which have already formed, or adults. It has a 30 day residual life and a second application will probably be needed. I would also recommend periodic adulticidal treatments in the brush around the swamp to control adults which have already emerged or those which emerge from untreated areas . The adult control material would be Scourge (a mixture of SBP-1382 and Piperonyl butoxide) , a low toxicity, but highly effective mosquito adulticide. This product would be used on vegetation only and not in the water. The first Altosid application should be made immediately with a follow-up in 30 days . I also would recommend beginning adulticide sprays immediately, and repeating them every 7-10 days until the problem is under control . I believe we can develop pathways through the swamp which will allow us access to breeding and adult resting sites . Once this is done treatments should be routine. I would expect my charges for the summer to be around $5000 . 00 including the cost of the Scourge . The Altosid cost would be extra, around $4000 . 00 per application. It may be possible to achieve control with a single application of Altosid. If you have further questions feel free to call . Sincerely, /M� �j Terry Whitworth,PhD �- CITY OF RENTON "LL PARKS and RECREATION Earl Clymer, Mayor John E. Webley, Director June 28, 1988 Dear Sirs: The Renton Parks and Recreation Department will activate the mosquito abatement program again this summer. The area to be treated is the Panther Creek Wetlands, located just east of SR-167. The program will consist of several applications. The Department of Ecology is currently reviewing the permit application. Once approval is received, treatment will begin immediately and continue throughout the summer months. The treatment will consist of a biological treatment of Altosid, a briquet placed throughout the water which prevents emergence of adult mosquitoes. This product will not effect pupae which have already formed, and treatments of adulticide spray in the brush around the swamp to control adults which have already emerged. The adulticide treatment will be every seven to ten days until the problem is under control. The City is bearing the cost of this treatment program and we are asking that you return the enclosed form giving your permission to spray the property you own in the Panther Creek area.. The treatment will be in the water and brush that immediatly surrounds the wetlands. Again, we will be using a biological treatment called Altosid Briquets and an insecticide adulticide spray called Scourge, a low toxicity highly effective on the adult mosquitoes. Treatment will begin within seven to ten days, so it is important that we receive your authorization and release form by July 7, 1988. Thank you for your cooperation on this matter. ely, Sin Park Superintendent SC:sw Attachment 200 Mill Avenue South - Renton, Washington 98055 - (206) 235-2560 r RENTON PARKS & RECREATION DEPARTMENT Below please find an "AUTHORIZATION AND RELEASE" that, when signed by you, will authorize us to inspect, analyze, and treat your property for the purpose of mosquito abatement in the Panther Creek Wetlands.

City staff and the Environmental Review Committee will then review this information, in order to then select a preferred system and issue a Determination. mmdoc 1 i the VIA o . �`. May 31, 1989 ,,OFFICE OF THE HEARING EXAMINER Ile CITY OF RENTON REPORT AND DECISION APPELLANT: CHRISTOPHER P. CLIFFORD (MOSQUITO ABATEMENT APPEAL - PANTHER CREEK WETLANDS) File No: AAD-035-89 LOCATION: East of SR167 between I-405 and SW 43rd Street. The site is approximately 65 acres. SUMMARY OF REQUEST: Appeal Environmental determination of Non-Significance for use of Altosid in the Mosquito Abatement Program for the Panther Creek Wetlands as proposed by the City of Renton Parks Department. PUBLIC HEARING: After reviewing the Appellant's written letter of appeal and examining available information on file the Examiner conducted a public hearing on the matter as follows: MINUTES The hearing was opened on May 16. 1989 at 1:30 P.M. in Courtroom #3 of the Renton District Court. Parties wishing to testify were affirmed by the Examiner. Throughout the course of the hearing the following exhibits were entered into the record: Exhibit #1 - Yellow File containing application, proof of posting and publication and other documentation pertinent to this request. Exhibit #2 - Printed label from Altosid. Exhibit #3 - Letter from Seattle Audubon Society to City of Renton SEPA officials, dated March 13, 1989. Exhibit #4 - Six-page excerpt from Book #1 of Agricultural Chemicals. Exhibit #5 - Environmental Review Checklist. Exhibit #6 - Technical Advisory Committee Staff Report dated February 15, 1989. Exhibit #7 - Environmental Committee Determination of Non- Significance (Mitigated) dated February 22, 1989. PERSONS IN ATTENDANCE: Lawrence Warren, Renton City Attorney Christopher Clifford, Appellant Lenora Blauman, Senior Planner Opening the hearing the Hearing Examiner clarified for those in attendance that this hearing will only deal with the matter of whether or not the city, through the Environmental Review Committee, made an error in its SEPA determination of Non-Significance for the proposed Mosquito Abatement Program scheduled for the Panther Creek Wetlands. Attorney Warren said after going through the record he realized the original appeal letter of March 10, 1989 contained three issues and the latest letter clarifying that appeal now contains seven issues. He asked that this hearing be limited to the original three issues of the March loth letter. The Examiner stated he would accept the second appeal letter as part of the substantiation for this appeal. Attorney Warren objected to the admission of the second letter just six days before this hearing. He also noted Christopher P. Clifford MOSQUITO ABATEMENT APPEAL (PANTHER CREEK) AAD-035-89 May 31, 1989 Page 2 his objection to the issue of conflict of interest raised in the appeal letter and did not feel it was related to the environmental issue. Mr. Clifford responded to the issue of conflict of interest noting the issue was raised as the city used Mr. Whitworth as a consultant to determine if this project was necessary and also to provide information contained within the environmental checklist. The Examiner stated he feels the information provided by Whitworth is subsidiary as the issue would be whether the information in the checklist is accurate and not whether Mr. Whitworth had a conflict in the preparation of the checklist. The Examiner did not feel the background of the consultant was an issue. Continuing, Attorney Warren referred to Mr. Clifford's letter of May 10, 1989 and two instances he (Warren) feels are hearsay, and stated testimony today will be the recitation of facts relayed from a third party which can not be authenticated. Ile made a motion that this hearsay testimony not be permitted. Mr. Warren also moved that the Examiner inquire of Mr. Clifford whether the testimony he intended to present today would be of a technical or hearsay nature. The Examiner stated because this is an administrative process it will be up to Mr. Clifford or his witnesses to show credibility for the testimony. Responding, Mr. Clifford acknowledged the hearsay information in the letter and stated it was only used to provide the Examiner with notice of where he obtained his information - but said he did not intend to use any witnesses from the Department of Agriculture nor did he plan to quote them, and will present factual, not hearsay information in his presentation today. Presenting an opening statement was appellant Clifford. Mr. Clifford set out the reasons for his appeal and basically reviewed his latest appeal letter which referred to the environmental checklist and the alleged omission or incompleteness of certain questions on that list which refer to the existence of mammals, fish and other animals in the Panther Creek Wetlands. Ile referred to a letter referencing the insecticide to be used and expressed concern about its growth hormone effect. Panther Creek Wetlands is 65 acres, and Mr. Clifford said he felt the amount of insecticide to be used would not be functional or cost-effective due to the size and density of the wetlands. Ile felt much of the area would be left untreated as 100% manual application is almost impossible, and said due to the fact the checklist failed to list the animals it may be in violation of RCW 77.16.120 calling for preservation of the nesting sites of raptors. Mr. Clifford also expressed concerns for possible chemical scourge; unknown effects of the treatment; believes an EIS should be required for the wetlands to determine the effect of the proposed program and provide mitigating conditions; and stated the Department of Ecology has not granted a permit for this program. Attorney Warren advised the permit from DOE is still pending and if the city does not receive the permit then the program will not proceed. Mr. Clifford continued and said a blower device suggested for use to spread the chemical will create a noise level that will disturb nesting animals and the environment. At this point he called for testimony from GERALD ADAMS, Seattle Audubon Society, 619 Joshua Green Building, Seattle 98101. Mr. Adams noted the Exhibit #3 letter was prepared pursuant to a telephone conversation he had with an individual at the National Pesticide Telecommunications Network on March 12, 1989, a service provided by Texas Tech University, and presented a brochure on the 24-hour hotline. The City Attorney objected to the information presented on chemical scourge and its toxicity as hearsay testimony from Mr. Adams because it was obtained from an unknown individual, over the telephone, who is not present and cannot be cross-examined. The Examiner permitted the testimony to continue. Mr. Adams continued stating the information he received from the Network by telephone was followed up by mailings which included information on chemical scourge and Altosid. The information was entered into the record as Exhibit #4. Because of the telephone conversation he said he became aware that there is very little known about chemical scourge, and read instructions for handling and cautions regarding scourge; the Audubon Society is concerned about the effect of scourge on water fowl and birds and it's penetration in the air. Attorney Warren objected to the acceptance of this unpublished information. Adams continued by offering the telephone number for Texas Tech to be used to verify the credibility of the information provided and again restated his objections to the proposed abatement program as contained in the letter of March 13, 1989. He said he spent about 45 minutes recently in the wetlands and relayed part of his observations as to the wildlife and water fowl present (such as Canadian geese, raptors, herons, owls and hawks). He said he tried to venture further into the Wetlands but decided not to disturb and possibly flush the wildlife. At this point Mr. Adams stated his concern regarding the application of insecticide briquets and their possible flushing of the birds and wildlife. Attorney Warren queried Adams about toxicity levels present through the spraying of scourge and Adams replied lie was not an expert and did not.have that information. Adams admitted that in his telephone conversation with Texas Tech he did not inquire about the concentrations or manner in which the chemicals were to be applied and was not sure if he had made such an inquiry. Adams said it was his understanding that scourge was to be applied by the City through the air and he clarified with city staff to be sure this did not mean the city would be making an aerial spraying of the wetlands. Adams stated there is a concern about the toxic effects of scourge on the water fowl because scourge would become present in'the water,if the wetlands were sprayed. j At this point Attorney Warren made.a move to dismiss all portions of the complaint as they relate to the application of altosid or any other method used by the city, with the exception of scourge as it Christclpher P. Clifford MOSQUITO ABATEMENT APPEAL (PANTHER CREEK) AAD-035-89 May 31, 1989 Page 3 related to applications that may get into the water and harm the water fowl. He felt all other testimony about this matter has been speculation and should not be admitted. Appellant Clifford asked the Examiner to refer to the label for Altosid which stated it is not to be placed in known fish habitats, and even if fish are not present, amphibians may be affected. Clifford stated he also believes the concern he expressed as to the omission of replies to questions #5 and Section 7, B (2 & 3) need to be dealt with. Terry"Whitworth Whitworth Pest Control 3707 96th Street East, Tacoma 98446, PYID Entomologist, presented testimony regarding altosid and scourge and described how scourge is suggested to be applied. He stated it is to be applied by using a back-pack sprayer and not to be applied in water. He said it could be possible for songbirds to be exposed to the spraying but when using a sprayer for application the sprayer makes enough noise the birds would disperse - he does not feel the impacts on birds would be significant. fie said most mosquitos tend to stay low in bushy areas so there would really be no reason to spray insecticide up in the air. Scourge is a general insecticide; altosid briquets will be applied one to every 10 sq. ft. and in the Panther Creek Wetlands, due to its denseness, it would not be possible to get 100% coverage - but a substantial reduction in mosquito population can be attained. He explained his process for selecting the Altosid briquets as opposed to using a liquid insecticide; toxic effects to non-target organisms is virtually non-toxic to those organisms at field concentration which is what the city would be applying; the toxicity of the briquets to be used is very low with a slow-release of their materials over a long period of time. Mr. Whitworth explained the effects of the altosid on larva and responded to concerns about possible contamination of non-target organisms such as birds, frogs and tadpoles. Mr. Clifford noted the use of Altosid would effect larva and asked if it would effect the "eggs" and Mr. Whitworth said it takes a very high concentration to have any impact. Mr. Whitworth also stated it is felt about 80% coverage could be attained in the wetlands and that should be good enough to achieve the abatement desires of the city. Upon continued questioning from appellant Clifford Mr. Whitworth replied there is a zone as you come out of the wetlands where the hillside begins to climb and where it first begins to flatten is the area the mosquitos tend to congregate; there is no reason for the insecticide to get into the water as it will be sprayed when there is no wind; the success of this spray on areas of comparable size has been determined to be great enough to justify this product and its use on the subject wetlands. Also called to testify was David Sullivan Zanus Corporation 1259 El Camino Real Suite 134 Menlo Park, California 94025 who, when asked by Attorney Warren for his educational credentials stated he holds a Bachelors Degree in Science and a Masters Degree in Entomology. Upon questioning Mr Sullivan acknowledged familiarity with the application of Altosid in large bodies of water; stated in Minnesota they treat over 4000 sq. miles with Altosid briquets which are of the larger variety that last about 150 days (which are larger than the briquets suggested for use in Panther Creek), with no environmental impact. He reviewed the application rate to be used and referred to Exhibit #4 regarding toxicity levels for fish, frogs and other animals; referred to other charts and information on application levels and their toxicity as compared to the level of application anticipated for this proposal; focusing on scourge - Sullivan said the likelihood scourge could get into the water, based on the rates the city will be using will pose little or no threat to the wetlands as the airborne particles are of such a size they tend to stay above and not drift down into water areas, and therefore is not likely to get into the water of the wetlands. Chemical scourge information has been reviewed by the Environmental Protection Agency who determined it to be safe, and any reference to scourge being toxic could be removed from the label. Ile said the use of scourge is of little or no risk and is considered one of the safest insecticides to be used as its chemicals are gone within four (4) hours. Cross-examined by appellant Clifford Mr. Sullivan stated lie does not feel Altosid would have any impact on the food chain because over the years as a reduction in the application rate has taken place it has been found that the natural predators have remained. I-ie stated lie did not believe scourge would have any impact on adult insects living in the wetlands and if there was an impact it would be minimal because of the way the product is used, the time of application, and how long it is in the environment. He said there is no other pesticide, to his knowledge, that would do the job it was intended to do and remain in the environment for a period of only four (4) hours - therefore the non-target organisms will not be harmed. Lenora Blauman, Senior Planner, City of Renton and Proiect Manager for the Mosquito Abatement Proiect, was called by Attorney Warren, and upon questioning stated with respect to scourge and Altosid she was responsible for contacting a number of sources with respect to the use and safety of those two chemicals. She said the results were placed in a report and also into the record separately at Exhibit #6 (which she read for the audience). Ms. Blauman said the Technical Advisory Committee presented this report to the Environmental Review Committee and after their review the ERC issued a Declaration of Non-Significance (entered as Exhibit #7). Ms. Blauman acknowledged she reviewed the Environmental Checklist for this proposal and if, or whenever a mistake is found every effort is made to correct the record. She did not feel a mistake was made on the checklist being discussed today. There were no more questions of any of the witnesses and the City and Appellant presented closing arguments. Christopher P. Clifford MOSQUITO ABATEMENT APPEAL (PANTHER CREEK) AAD-035-89 May 31, 1989 Page 4 Appellant Christopher Clifford stated he feels the mistakes on the Environmental Checklist need to be rectified, conditions need to be acknowledged and mitigation proposals need to be set forth by the city. The omission of animals, and the blower to be used and it's decibel levels are of concern to him and should be to the city. The density of the wetlands leads him to believe the application of Altosid may not be effective. The wetlands of Renton are the largest in the area and the future plan for this area should be that it be set aside for a greenbelt and a habitat for animal life. He requested that an Environmental Impact Statement be prepared for the Panther Creek Wetlands to recognize any impacts on any!wildlife in the area and definitive mitigating measures should be set forth to correct any impacts. Mr. Clifford expressed the need for the city to proceed as carefully as possible before a chemical treatment approach is used to protect the wildlife in the area that will be adversely affected as a result of this program. Mr. Clifford acknowledged something should be done about the mosquitos in the wetlands area but he is not sure this is the program that should be used. The Hearing Examiner requested Sr. Planner Blauman to read to the audience the ERC mitigation conditions to enlighten them as to the precautions and concerns considered by that Committee. Closing argument from City Attorney Lawrence Warren included his reference to RCW 43.21C.031 which requires an Environmental Statement for all proposals having probable significant, adverse impacts and he felt testimony given today referred to strictly speculative impacts that were of concern. He said speculative impacts would have to be gross speculation in order to arrive at a significant environmental impact. The concentrations of Altosid are 1/2000th of that which would be necessary to have toxic effects on fish. Scourge and the method it is supposed to be applied has a short life of only 4 hours and would not get into the water in significant concentrations and is not a threat to birds whether water fowl or raptors - with no affect on their food source. Mr. Warren feels we-have an improbably, insignificant, non-adverse environmental impact which is the reason the DNS was correct in being issued. Referring to the alleged mistakes or omissions in the Environmental Checklist, Mr. Warren felt that issue was irrelevant as it has been shown by testimony given today that the creatures were not mentioned because staff did not feel they would be harmed. The level of technical information presented in testimony today would show there is no probable negative environmental impacts and the only contrary testimony given was considered hearsay testimony received from an unidentified individual taken by telephone, without reference to methods and concentrations of applications. He feels at the very best this testimony should be considered speculative. Attorney Warren stated the responsible official under SEPA can not base a decision requiring an Environmental Impact Statement on speculative environmental effects. Ile concluded it was his feeling there is no reason to set aside the subject DNS for this proposal. The Examiner called for further testimony regarding this proposal, There was no one else wishing to speak, and no further comments from staff. The hearing closed at 3:50 P.M. FINDINGS, CONCLUSIONS & DECISION: Having reviewed the record in this matter, the Examiner now makes and enters the following: FINDINGS: 1. The appellant, Christopher P. Clifford, challenged a Determination of Non-Significance issued for a Mosquito Abatement Program operated by the City of Renton. The city initially issued a Determination of Non-Significance (DNS) for its Mosquito Abatement Program (MAP) for the Panther Creek Wetlands, the subject proposal, on February 22, 1989, with a publication date of February 27, 1989. The DNS contained mitigating conditions making the DNS, a DNS-M. The publication triggers a comment period and an appeal period. Both the appellant and the Department of Ecology (DOE) submitted comments or requests for additional information. These comments delayed the original appeal period and extended the time for appeals to April 3, 1989, which was fourteen days from the issuance of the DNS-M on March 20, 1989. The appellant filed a timely appeal on April 3, 1989. The Public Hearing was scheduled and held on May 16, 1989. 2. The Panther Creek Wetlands (wetlands) are located east of SR 167 (East Valley Highway), west of Talbot Road, north of S.W. 4.3rd Street and south of 1-405. They can most easily be seen from the northbound lanes of SR 167. Portions of the wetlands and uplands are owned by the City of Renton, with the remainder in the hands of private parties generally owning homes or vacant properties located on the uplands east-of the wetlands. 3. The wetlands are approximately 65 acres in size. Besides being home to a variety of wetland plants and animals, the wetlands are the home of Coquillettidia perturbans, a particularly large variety of mosquito. 'Christopher P. Clifford MOSQUITO ABATEMENT APPEAL (PANTHER CREEK) AAD-035-89 May 31, 1989 Page 5 4. Apparently, responding to public complaints last year and this year, the city determined to abate the problems created by the mosquito population and apply chemical agents to ameliorate the problem. Complaints regarding mosquitos have already been received by the city. 5. While the city had used control measures in the past, for a number of years they had abandoned public efforts to control mosquitos in this area. They had attempted to initiate this program last year but the environmental process was begun late. After the filing of an appeal by this same appellant, the program was abandoned since the time frame of hearing, decision and appeal period would have made the program ineffective as the window for effective application would have passed. 6. The city initiated its application earlier this year in order to fit the program within the effective window. 7. The MAP would require the application of two separate chemical agents to the wetlands or areas surrounding the wetlands. Each agent provides a different form of mosquito control or eradication. One agent retards mosquito maturation, freezing, if you will, development at a stage short of adulthood, the stage when mosquitos bite and reproduce. The second agent actually kills adult mosquitos, effectively preventing biting and reproduction. 8. The first agent is Altosid which is a trade name. It is formulated in a clay briquet. The common name of the active ingredient is Methoprene. The briquets are applied at a rate of approximately one (1) briquet per ten (10) square feet of surface water. The application rate varies for water of greater depth or with varying flow rates. As the clay dissolves•the methoprene is released in a "time-release" fashion. The agent affects the larval stage of the developing mosquito. The larvae develop "normally" to the pupal stage but development is then halted and the pupal stage mosquitos do not develop into adult mosquitos. The pupal stage mosquitos then die. This agent does not halt development once mosquitos reach the pupal stage, and adult mosquitos would emerge from the wetland. It also has no affect on adult mosquitos. 9. The evidence reflects that both the larval stage and the pupal stage mosquitos are available to support the food chain, although adult mosquitos, apparently reduced in numbers by this agent, would not be. Also, if the program were effective no, or substantially reduced, juvenile form mosquitos would be present in the food chain in the future. 10. Persistence studies of Altosid applied to soil in extremely large amounts demonstrates a half-life (the time for the quantity to be reduced by half through chemical or metabolic breakdown) was approximately 10 days. Applications in water under normal conditions of sunlight and temperature shows a half-life of approximately 2 days. Experiments have shown that there is no uptake in plants. Mammaian metabolism converts the substance to ordinary waste products or passes it through. Methoprene is administered to beef and dairy cattle to reduce the fly population around feed yards. 11. The studies have demonstrated low toxicity. It has been shown to have no mutagenic (modified species development) or teratogenic (abnormal fetal development) or other reproductive affects on small mammals. It has shown low or no significant levels of eye or skin irritation in rats, rabbits and domestic pets. It does not appear to affect birds or waterfowl. 12. Altosid is not recommended for bodies of water which support fish habitat. The wetlands apparently do not support fish populations. 13. The applicant proposes applying the Altosid according to standard practices, and physical application will require using sling shots to apply it to interior regions of the wetland. 14. Altosid has been used over large areas in Minnesota where it is applied while wetlands are frozen over in winter. The briquets are simply dropped on the snow or ice overlying wetlands. The briquets enter the water during the thaw and begin dissolving upon entry. 15. The second agent which would be employed in the MAP would be Scourge. Scourge is the brand name of an insecticide containing as its active ingredients a synthetic version of Resmethrin and Piperonyl butoxide. Resmethrin is a natural constituent of some plants. It apparently possesses insecticidal properties. The intent of applying Scourge is to kill any adult :,mosquito which has already emerged from the wetland, having been missed by the Altosid application. 16. Scourge is persistent for approximately four (4) days, although some studies show it breaks down under ultraviolet light in approximately four (4) hours and does not accumulate in the environment. It is an insecticide which kills mosquitos on contact. It begins a natural °} �;,;i-t; kbreakdown upon exposure to sunlight and air. Christopher P. Clifford MOSQUITO ABATEMENT APPEAL (PANTHER CREEK) AAD-035-89 May 31, 1989 Page 6 17. Scourge may be toxic to fish and recommendations for its application suggest that it not be applied when breezy or windy to avoid its drifting over water bodies. It is not to be applied directly over water bodies. It does not demonstrate significant mutagenic or teratogenic properties, nor oncogenic (cancer inducing) properties. 18. Scourge is applied by fogging or spraying vegetation surrounding the wetland. Field investigations have shown that the lower bushes and shrubs surrounding the wetland harbor adult mosquitos. 19. A variety of measurements including LD0 and LCSQ (mean lethal dose and mean lethal concentration, the rate at which half of the tested animals die), ppm (parts per million), and mg/kg (amount per weight) are found in the studies and labels submitted for these two products. The evidence suggests that only in quantities many times, in some cases thousands of times as much as the proposed application are the affects acute, toxic, or lethal. Tile application of Altosid will amount to .0024 to .0098 ppm or approximately .009 - .037 mg/gallon of water. The recommended application of Scourge is 0.007 pounds per acre. The tested lethal doses were from hundreds to thousands of times greater. Of course, some of these potentially harmful doses are still relatively small - measured still as only 5000 parts per million. See Exhibit 4, incorporated by reference. 20. The city's DNS-M contained the following conditions: 1. That, in order to ensure viable, safe habitation/use of properties in the area of the Panther Creek Wetland, the applicant,.for 1989 and 1990 only, utilize the products Altosid and Scourge for mosquito abatement, as instructed/permitted by the Department of Ecology and the King County Health Department. 2. That, in order to ensure the necessity/efficacy of the 1989 and 1990 abatement program, the applicant shall develop and adhere to a plan by which a licensed entomologist will undertake monitoring and testing of traps at regular intervals to: a) provide a census; b) recommend an application plan, recognizing that more than one application may be necessary to achieve vector control; and c) monitor the application process to ensure that product application is scheduled at times of the day and in weather conditions which maximize the effectiveness of abatement control and minimize impact upon the human/natural environment. 3. That, in order to preserve the natural environment of Panther Creek Wetlands and Springbrook Creek, during the 1989 and 1990 abatement program, the applicant shall: a) consult with the Department of Wildlife; b) invite comment from the Department of Fisheries. These communications shall take place in advance of each product application during 1989 and 1990 to establish the continuing appropriateness of the proposed systems/products to be used and the application schedule in the event that there are changes in the existing habitat which warrant such approval. 4. That, in order to ensure public health and safety, the applicant shall: a) provide written information which fully describes the abatement program and schedule to all individual homeowners within the proposed project area along Talbot Road; b) provide written information which fully describes the abatement program and schedule to be published in a local newspaper and posted at regular intervals in the vicinity of the project area; and c) provide notification for/conduct a public meeting to inform interested parties about the proposed abatement project. All notifications should include the name and telephone number of a City representative who can provide further information about the program to interested parties. The City will not conduct mosquito abatement activities on private property without permission of the property owner. Note: Staff recommend that the above-described information programs be implemented prior to the completion of the comment period for the environmental determination. (1/t; oc clic.! !'

That, in order to protect the human environment and the natural environment: a) the applicant shall reconfirm the suitability of the proposed (Altosid, Scourge) chemical system on an annual basis, over the life (1989-1993) of this project; and b) the applicant shall submit a new application if new chemical systems or products (other than Altosid or Scourge) are selected by the City/suggested by DOE during the life of the project (1989-1993). Note: Unless the Panther Creek Wetlands Habitat is to be developed within the next two years with a wildlife habitat which will provide biological control of mosquitoes, the Public Works and Parks Departments should work together to provide, prior to the end of calendar year 1991, a comparative analysis which explores options for mosquito abatement through biological control systems, natural selection systems, water manipulation, mechanical control and the proposed chemical control system, including a description of the components of those systems, anticipated positive and negative impacts of each system (e.g. feasibility, efficacy, efficiency, safety), and required mitigation measures. City staff and the Environmental Review Committee will then review this information, in order.to then Select a preferred system and issue a Determination. 21. Findings 22 through 25 below refer to answers on the Environmental Checklist prepared by the applicant for MAP and the application of the two chemicals to the Panther Creek Wetland. The applicant indicated on the Checklist that it was for the program for the years 1989'to 1993 and for insecticides approved each year by the Department of Ecology. 22. In filling out the checklist the applicant listed waterfowl as the only avian species observed on or near the site or known to be on or near the site, leaving un-checked or un-circled choices including hawk, heron, eagle, and songbirds. The site was not listed as part of a migration route. Similarly, no mammals were identified as being on or near the site. The list names only larger mammals but includes "other" as a fill-in choice. No threatened or endangered species were listed on the checklist.. The appellant demonstrated a variety of birds and raptors live on or frequent the site. 23. Under environmental health which requires identification of health hazards and possible toxic exposure, the applicant identified the two agents - Altosid and Scourge. The Fire Department and Medic One were listed under emergency services which might be required. No particular method was listed to reduce or control environmental health hazards. The applicant indicated the materials.will be used according to label directions. 24. SR 167 was listed as a source of noise as was the backpack blower/applicator used to deliver Scourge. No measures were identified to reduce noise impacts. The applicant stated the background noise of the highway would drown out the backpack blower unit. 25. The site was identified as "environmentally sensitive" containing wetlands, serving as greenbelt gnd;within the .100-year flood plain. CONCLUSIONS 1. The decision of the governmental agency acting as the responsible official is entitled to substantial weight. Therefore, the determination of the.Environmental Review Committee (ERC), the city's responsible official, is entitled to be maintained unless the appellant clearly demonstrates that the determination was in error. 2. The Determination of Non-Significance in this case is entitled to substantial weight and will not be reversed or modified unless it can be found that the decision is "clearly erroneous". (Hayden v. Port Townsend, 93 Wn 2nd 870, 880, 1980). The court in citing Norway Hill Preservation and Protection Association v. King County Council, 87 Wn 2d 267, 274; 1976, stated: "A finding is 'clearly erroneous' when although there is evidence to support it, the reviewing court on the entire evidence is left with the definite and firm conviction that a mistake has been committed." Therefore, the determination of the ERC will not be modified or reversed if it can meet the above test. For reasons enumerated below, the decision of the ERC is affirmed. 3. The clearly erroneous test has generally been applied when an action results in a DNS since the test is less demanding on the appellant. The reason is that SEPA requires a thorough examination of the environmental consequences of an action. The courts have, therefore, made it easier to reverse a DNS. A second test, the "arbitrary and capricious" test is generally applied when a Determination of Significance (DS) is issued. In this second test an appellant would 'Christopher P. Clifford MOSQUITO ABATEMENT APPEAL (PANTHER CREEK) AAD-035-89 May 31, 1989 Page 8 have to show that the decision clearly flies in the face of reason. A Declaration of Significance which results in the preparation of a full disclosure document (an Environmental Impact Statement) is more difficult to overturn since it is more protective of the environment. 4. An action is determined to have a significant adverse impact on the quality of the environment if more than a moderate impact on the quality of the environment is a reasonable probability. (Norway, at 278). Since the Court spoke in Norway, WAC 197-11-794 has been adopted and it defines "significant" as follows: Significant. (1) "Significant" as used in SEPA means a reasonable likelihood of more than a moderate adverse impact on environmental quality. (1) Significance involves context and intensity ...Intensity depends on the magnitude and duration of an impact.... The severity of the impact should be weighed along with the likelihood of its occurrence. An impact may be significant if its chance of occurrence is not great, but the resulting environmental impact would be severe if it occurred. 5. Also redefined since the Norway decision was the term "probable." Probable. "Probable" means likely or reasonably likely to occur, ... Probable is used to distinguish likely impacts from those that merely have a possibility of occurring, but are remote or speculative. (WAC 197-11- 782). 6. Impacts also include reasonably related and foreseeable direct and indirect impacts including short-term and long-term effects. (WAC 197-11-060(4)(c))- In this case consequences of the MAP to the food chain, that is the interdependence of other specifies on insects such as the mosquito as a food source could be reasonably related. The ERC's analysis of the two chemicals, along with the consultants' information, demonstrates that there should be limited impacts upon the food chain. The Altosid works on the juvenile mosquito forms. The larval forms, as well as the pupal forms, will be available as a food source for amphibians and other water feeders. The metamorphosis will stop at the pupal stage so that adult mosquitos will not emerge. Those mosquitos which do emerge due to late or incomplete application of Altosid will be exterminated by the Scourge. Unanswered though is what impacts might result from the elimination of juvenile mosquito forms from the food chain if the process is effective. 7. The proposed MAP will apply very small amounts of two known chemical agents, Altosid and Scourge, to the wetland environment. Altosid will be applied to the water and Scourge will be used at low volumes to spray vegetation adjacent to the wetland. A number of studies have been conducted on those two agents and while they may have harmful affects if applied improperly (a violation of federal law) they have been generally shown to have limited impacts on supposed non-target species. 8. While the applicant, City of Renton, did make some errors in filling out the Environmental Checklist, those errors did not substantially impair the result. Adding a number of birds, small mammals and amphibians to the checklist would not have altered the fact that the chemical agents chosen apparently have little, if any, impact on the species named, or even those omitted from the checklist. 9. Therefore, as defined by SEPA, there appears little likelihood that the MAP will have more than a moderate impact on environmental quality, or that the impact or impacts would be severe. Nor do impacts seem more likely to occur as opposed to less likely, again, given the lawful and proper application of these agents. 10. The appellant did raise some valuable questions regarding possible impacts. Particularly since the program is proposed to be on-going, it seems logical to establish some form of methodology to determine if field studies besr out the clinical observations. The ERC has established a methodology to determine if the agents are effective against mosquitos when clinical evidence demonstrates that it should be without further testing. So while a census of mosquitos will show whether the eradication program is working or not, it will not show if the wetland is in some way altered. It will not show what impact the future loss of juvenile mosquitos will have on other animals which use them as a food source. Chrivopher P. Clifford MOSQUITO ABATEMENT APPEAL (PANTHER CREEK) AAD-035-89 May 31, J1 989 Page 9 IL Therefore, the decision of the ERC should include additional conditions to assure that the wetland environment is not substantially altered. As field observations will be used to determine if the mosquito population has been reduced, field observations should be conducted to determine if fauna relying on the wetland habitat for shelter or food are also in any way adversely affected by the MAP. The city shall be required to conduct a census of birds, fish, amphibians, and small and large mammals prior to treatment of the wetland with any chemical agents. It shall then conduct a similar census in subsequent years to determine what if any impact the treatment has on the existing fauna. 12. The initial census will establish a baseline of existing fauna. Without such baseline information it will be difficult, if not impossible, to determine if the treatment program is harming the wetland or species that depend on the wetland for habitat or food. As staff indicated, the DNS was to be periodically reviewed for subsequent years. If subsequent review is envisioned then that subsequent environmental review would benefit from having sufficient information to conclude what impacts treatment of the wetland has had. 13. Conditions 2 and 5 of the DNS-M both suggest that preservation of the natural environment of the wetlands is also a goal of the city. Therefore, mosquito eradication and wetland preservation should not be handled in such a manner that either goal excludes the other. The issue is not as simplistic as preserving the wetland as a mere holding system for storm water. In order to have a viable wetland the MAP cannot alter the wetland by diminishing or eliminating wetland fauna, its inhabitants or visitors, with the exception of mosquitos and possibly some other non-target, "non-important" insects. If the purpose of the wetland were mere detention, then an EIS would probably be required as that would be a major alteration of the existing habitat and environment. Indirectly causing that result through inadvertent alteration of the wetland would require no less - an EIS. The baseline study will permit monitoring to assure that inadvertent alteration does not continue if it in fact is occurring. 14. The ERC did not simply issue a DNS, it also imposed a series of conditions to assure the health and safety of nearby residents and conditions to avoid unnecessary treatment if other methods prove sufficient. These conditions, supplemented by the additional condition requiring an initial wildlife census and annual census to determine if an impact has occurred, will assure the integrity of the SEPA process. 15. The reviewing body should not substitute its judgment for that of the original body with expertise in the matter, unless the reviewing body has the firm conviction that a mistake has been made. The record does not disclose that there has been sufficient error of substantive value to require reversal of the determination issued by the ERC. There is no doubt that the reviewing agency could have presented a more accurate checklist, but the errors complained of are not significant in light of the apparently limited consequences of applying these chemical agents as specified by their respective labels. The inclusion of the additional condition regarding a baseline wildlife census will insure that if any impacts are revealed future programs will be modified or, in fact, an EIS will be prepared. DECISION The determination of the Environmental Review Committee is affirmed with the following modification: The following condition shall be added to the DNS-M: The city shall be required to conduct a census of birds, fish, amphibians, and small and large mammals prior to treatment of the wetland with any chemical agents. The initial census shall establish a baseline of existing fauna and shall be conducted in a formal, professional manner and shall include the normal m l dology utilized to conduct field observations of species in their native environment. The observations shall also be required to include those species that reside on the wetland and those that utilize it as a source of food. It shall then conduct a similar census in subsequent years to determine what, if any, impact the 5" treatment has on the existing fauna. r \ RADI THIS 31st day of May, 1989. 9 V, FRED J.

Clifford MOSQUITO ABATEMENT APPEAL (PANTHER CREEK) AAD-035-89 May 31, 1989 Page 11 Pursuant to Title IV, Section 3015 of the City's Code, request for reconsideration must be filed in writing on or before 5:00 P.M. June 14, 1989. Any aggrieved person feeling that the decision of the Examiner is ambiguous or based on erroneous procedure, errors of law or fact, error in judgment, or the discovery of new evidence which could not be reasonably available at the prior hearing may make a written request for a review by the Examiner within fourteen (14) days from the date of the Examiner's decision. This request shall set forth the specific ambiguities or errors discovered by such appellant, and the Examiner may, after review of the record, take further action as he deems proper. Any appeal is governed by Title IV, Section 3011, which requires that such appeal be filed with the Superior Court of Washington for King County within twenty (20) days from the date of the Examiner's decision. The Appearance of Fairness Doctrine provides that no ex parte (private one-on-one) communications may occur concerning pending land use decisions. This means that parties to a land use decision may not communicate in private with any decision-maker concerning the proposal. Decision-makers in the land use process include both the Hearing Examiner and members of the City Council. All communications concerning the proposal must be made in public. This public communication permits all interested parties to know the contents of the communication and would allow them to openly rebut the evidence. Any violation of this doctrine would result in the invalidation of the request by the Court. The Doctrine applies not only to the initial public hearing but to all Requests for Reconsideration as well as Appeals to the City Council. r t Nef Ok s j A-90v0`00' R-2100' T-2100' .
